The first hidden groove and the second hidden groove are formed in the left inner wall and the right inner wall of the door frame and hinged to the closed plate through hinges respectively. The multifunctional aluminum alloy door has the advantages of having a daily thievery prevention, wind and rain prevention, cold prevention and sunstroke prevention functions, solving the problem that clothes can not be conveniently hung and aired at home through a stretch type clothes hanging device of the multifunctional aluminum alloy door, greatly saving space by arranging a clothes hanging rod in a wall behind the door frame and being convenient to use.

The invention discloses a surgical instrument for a minimally invasive surgical robot and a minimally invasive surgical robot. The surgical instrument comprises a front-end driving portion, a guide rod portion and a tail-end execution portion in sequential connection. The tail-end execution portion comprises a wrist device and a tail-end execution device in sequential connection. The front-end driving portion comprises a deflection driving device, an opening-closing driving device and a rotation driving device. The deflection driving device is used for driving a deflection angle of the wrist device, and the opening-closing driving device is used for driving openness of the tail-end execution device. By the wrist device of the minimally invasive surgical robot, deflection of degrees of freedom of two sides can be realized so as to drive the tail-end execution device to defect without affecting openness of the tail-end execution device, and accordingly surgical operation flexibility of the robot is improved.

The invention discloses a floating dock for partial repair of ship bottom, which comprises an underwater part, including an operation cabin with an opening facing upwards, and the mouth of the operation cabin is in sealing contact with the bottom of the ship to be repaired; the upper water part is connected with one end of the underwater part and is upward Extended, the water surface is located above the liquid level, the water surface includes the cab, the maintenance personnel room, the maintenance personnel room has a personnel pipeline connected with the operation cabin; the sealing drainage mechanism includes a waterproof pad arranged on the edge of the operation hatch, The waterproof pad protrudes upwards, and the inner ring of the waterproof pad is also provided with a gutter that is not connected with the operation cabin. Adopting this invention, the overall tonnage is small and the cost is low, and a water-proof operation cabin cavity can be partially formed at the bottom of the ship to be repaired, which is convenient for personnel to accommodate and perform maintenance.

The invention relates to an oil seed roasting machine sealing pan cover and pan cover opening and closing device which comprises a pan cover, a feed pipe, an articulated four-link mechanism, a manual operating rod, a transmission shaft, a crank shaft push rod mechanism and an automatic pan cover opening electric control part, wherein a hole where the feed pipe is mounted in a penetrating manner is formed in the center of the pan cover; a bearing is mounted between the feed pipe and the center hole of the pan cover; pan cover hinged shafts are symmetrically mounted on the two sides of the feed pipe; the two ends of the hinged shafts are movably connected with the articulated four-link mechanism symmetrically arranged on the two sides of the pan cover respectively; the transmission shaft connected with the articulated four-link mechanism is arranged at the lower part of the pan cover; the manual operating rod is mounted on the transmission shaft; and the transmission shaft is connected with the crank shaft push rod mechanism arranged at the lower part. According to the device, the pan cover adopts a movable sealed structure, and can be clung to a roller pan port to automatically seal the pan port by the articulated four-link mechanism; the practical effects of flexible pan cover opening and closing, and convenient feeding and discharging can be realized; the pan cover can be opened and closed manually or opened automatically; manual operation and automatic operation do not affect each other; and the device is simple and flexible to operate and convenient to use.

The invention discloses a rotation stopping type door opening and closing speed limiter which is composed of a bracket, a rolling wheel and a pendulum hammer. The bracket comprises a door connecting plate and three rolling wheel connecting plates, an annular baffle is arranged on the inner side of the right side rolling wheel connecting plate, and two baffles are symmetrically arranged in the annular baffle; a rolling wheel main body is a cylinder, the center of the left side of the cylinder is provided with a shaft, the center of the right side of the cylinder is provided with a long shaft, apendulum bob connecting frame is arranged on the top of the long shaft and comprises two rectangular plates, and the rectangular plates are provided with pendulum bob connecting holes; a mass block is arranged at one end of the pendulum bob, and a pendulum bob connecting shaft is arranged at the other end of the pendulum bob; after the speed limiter is installed on the door, the rolling wheel fits the ground; when the door is opened and closed, the friction between the rolling wheel and the ground can drive the rolling wheel to rotate; when the door opening and closing speed exceeds the set speed, the pendulum bob swings outwards under the centrifugal action, the baffles in the annular baffle of the bracket are hooked, the rolling wheel stops rotating, and the door is slowed down. The problem that an existing door is not restricted when the door is half opened / closed is solved.

The present invention relates to the technical field of fast conveying equipment for vertical elevators, in particular to an express storage and delivery device for lift elevators, which includes a main car body, a traction machine, an inclined express storage box, an external delivery box, an external output box and Adjust the motor. An express delivery storage and delivery device for an elevator of the present invention is provided by installing an oblique express storage box for storing and transporting express delivery on the outer wall of the main body, an arc-shaped material guide pipe connected with the oblique express storage box, and a The side-turning guide tube controlled by the adjustable motor is connected with the external delivery box and the external output box on different floors through the side-turning guide tube, so that the express can be automatically delivered to the external output box on different floors. Inside the box, there is no need for couriers to frequently take the elevator and wait for the elevator, and the delivery efficiency is greatly improved; the side-mounted adjustment motor is used to control the turning of the side-turning guide tube, which does not affect the opening and closing of the elevator's inner and outer translation doors, and the structural layout is more reasonable. Applicability is greatly enhanced.

The invention discloses a downward pressing rotation stopping type door opening and closing speed limiter which is composed of a support, a rolling wheel, a pendulum bob, elastic rubber and an installation connecting frame. The main body of the rolling wheel is a cylinder, a shaft is arranged in the center of the left side of the cylinder, a long shaft is arranged in the center of the right side of the cylinder, a pendulum bob connecting frame is arranged at the top end of the long shaft and comprises two rectangular plates, the rectangular plates are perpendicular to the central axis of the long shaft, and pendulum bob connecting holes are formed in the rectangular plates. After the limiter is installed on a door, the rolling wheel is attached to the ground, during door opening and closing, the rolling wheel can be driven to rotate under the friction action with the ground; when the opening and closing speed of the door exceeds a set speed, the pendulum bob swings outwards under the action of centrifugal force to hang a baffle in an annular baffle of the support, the rolling wheel stops rotating, and after the rolling wheel stops rotating, the support rotates around the rotating shaft under the action of friction force, so that the support generates downward pressure, the friction force is increased, and deceleration of the door is achieved. The problem that an existing room door is not limited when the room door is in a semi-opening and semi-closing state is solved.
