The invention relates to a detachable four-pivot guiding connector used for distributing and collecting diving instruments, comprising a frame and cable-threading holes arranged in the middle of the frame. The detachable four-pivot guiding contact is characterized in that a hanging board is respectively arranged on two sides of the cable-threading holes on the frame, a pin-roll hole is arranged at an upper end of the hanging board, and front and back elastic stabilizers, including two front elastic stabilizer and two back elastic stabilizer, are respectively arranged at four corners of the lower part of the frame; an anti-cross-shaking buffer connecting base is respectively arranged on two sides of the disc-shaped frame, and a connecting pin-hole is respectively arranged at ends of the anti-cross-shaking buffer connecting base. With the invention, not only the hang of the guiding connector and diving instruments becomes so convenient but the support state is also stable; and the buffering capability is excellent with better anti-shaking and anti-swaying effect and higher distributing and collecting security in virtue of the elastic stabilizers and anti-cross-shaking buffers, so as to enhance the adaptability of the diving instruments to sea conditions. The detachable four-pivot guiding connector of the invention enhances the universality and available efficiency of distributing and collecting instruments so as to largely raise the voyage-sequence utilization efficiency of mother ships.

The invention discloses a spliced type ring main unit. The ring main unit comprises a cabinet body and three ring main units. The three ring main units are located in the cabinet body. A shielding cover is arranged at an upper end of the cabinet body. A fan is installed at the upper end of the shielding cover. A protective cover is arranged on the shielding cover above the fan. Two groups of number one sliding grooves are arranged in a bottom end of an internal portion of the cabinet body, two groups of number one sliding rods are fixedly connected to lower ends of the three ring main units, the three ring main units are slidably connected with the bottom end of the cabinet body through the two groups of number one sliding rods and the number one sliding grooves, and a number one buffer device is arranged on one side of each of the three ring main units. By using the spliced ring main unit and the using method thereof, the ring main units of different sizes can be fixedly spliced in the cabinet body, the ring main units can move in one direction in a splicing process, a buffering effect is achieved in a ring main unit moving process, an effect of protecting the ring main units andthe cabinet body can be achieved, and practical performance is achieved.

A fan arrangement of a portable handheld work apparatus is driven by an internal combustion engine and includes a radial fan (1) which includes a fan wheel (5) and a spirally-shaped fan housing (6) which encloses the fan wheel (5) at least partially. A take-out opening (3) is provided in the radial fan (1) in the region of the moved air flow (2) for diverting a combustion air flow (4) for the engine. The combustion air flow (4) is branched off from the air flow (2). In the radial direction outside of the fan wheel (5), there is an aerodynamically formed guide ramp (7) provided in the air flow (2) which rises in the axial direction. The take-out opening (3) is arranged downstream of the guide ramp (7).

The invention discloses an electronic crane scale placing and moving device, which enables the electronic crane scale without bumping a drop hanger when placed. The electronic crane scale is not jolted in moving process and convenient to push. The technical solution is an electronic crane scale placing and moving device comprising a main body connected with a spring adjacent to both sides of the bottom surface. Another end of the spring is connected with a base respectively connected with two directional wheels and at least one universal wheel adjacent to both ends on opposite surface of the spring. The electronic crane scale is placed on the electronic crane scale placing and moving device when stored and moved. The device has simple structure, and is compact, which not only avoids bumping a drop hanger when stored but also convenient to change direction and lighten shake of the crane scale. The device can be applied to occasion that the electronic crane scale is commonly used and moved.

The invention relates to the field of vehicle body parts, and provides a vehicle door structure. The vehicle door structure comprises a vehicle door outer plate, a decorative plate located on the outer side of the vehicle door outer plate, and a decorative strip. The decorative plate comprises a body plate and a doghouse part arranged on the inner surface of the body plate. A first clamping pieceis clamped on the doghouse part, the first clamping piece can be inserted into a clamping hole in the vehicledoor outer plate in the direction from outside to inside so as to be clamped on the lower portion of the vehicle door outer plate, and the decorativestrip is arranged on the outer surface of the body plate. According to the vehicle door structure, the lower portion of the vehicle door outerplate is covered with the decorative plate, the vehicle door outer plate can be protected against collision of splashed sundries through the decorative plate, the decorative plate can be detached, the damaged decorative plate is allowed to be replaced, the whole vehicle door does not need to be replaced, and the maintenance cost is reduced.

The invention discloses an unmanned aerial vehicle with an anti-collision function. The unmanned aerial vehicle comprises a vehicle body. A base is arranged and fixed at the bottom end of the vehiclebody, and the two sides of the base are connected with connecting rods through hinges. One ends of the connecting rods are fixed to one ends of springs in a welded mode, and the other ends of the springs are fixed to the inner wall of a connecting block in a welded mode. The outer wall of the bottom end of the connecting block is fixed to one side of a support in a welded mode, and one end of thesupport is connected with one end of a first supporting rod through a hinge. The other end of the first supporting rod is connected into a second supporting rod in a sleeved mode, and the other end ofthe first supporting rod is connected with one end of a steel wire in a fastened mode. The other end of the steel wire is fixed to one end of the fixing block in a welded mode, and the fixing block is connected and fixed to the middle of a rotary shaft in a sleeving mode. One end of the rotary shaft is fixed to the output end of a motor, and the top end of the motor is fixed to the bottom end ofthe base in a welded mode. According to the unmanned aerial vehicle, during collision, the vehicle body can be more stable, and the anti-collision capacity of the unmanned aerial vehicle is improved.
