The invention discloses a double-layer multi-hole dust-retention barrier based on the elastic splaying of leaf surfaces of rice. A rigid multi-hole dust-retention net with hollow round meshes and a limiting hole is arranged on the outer side of the barrier, a flexible super-hydrophobic cleaning net with four-leaf solid meshes and a limiting hole is arranged on the inner side of the barrier, the hollow round meshes, four-leaf solid meshes and the limiting holes are formed in a one-to-one correspondence manner, central points in pairs coincide, and net pieces on the inner and outer sides are limited by limiting-fixing components and are fixedly connected. The meshes of the flexible super-hydrophobic cleaning net of the double-layer multi-hole dust-retention barrier are of a four-leaf solid mesh design, the passive adjustment of the porosity is realized by virtue of elastic splaying of leaves, and the size of incoming wind resistance can be effectively adjusted, so that the contact area between the meshes and fine particulate matters is increased; and the barrier is woven by virtue of high-strength polyester fiber silk yarns, the surface of the barrier is processed by virtue of a Nano-Sphere coating technique, a rice-leaf-similar super-hydrophobic surface is formed, and the self-cleaning property of the surface of the barrier is utilized, so that the fine particulate matters can be effectively adsorbed and captured, and the dust retention effect is improved.

The invention discloses a picking device for fresh wolfberry fruits. The device comprises chassises, a fruit collecting plate, major arms, branch-collecting arm mounting seats, a chain-bucket elevator, baffle plates, side frames, a power unit, a holding handle, a fruit collecting box, wheels, feather hands, branch-collecting arms, a control box and top supporting frames. The invention also discloses an application method for the picking device. According to the method, the whole picking device is driven to straddle on a ridge of a wolfberry field under the driving force provided by the power unit and longitudinally moves forward along the ridge of the wolfberry field; a wolfberry tree passes through the interior of a door-shaped structure under the picking device; when the branch-collecting arms on the picking device move forward, fruit-bearing branches are drawn out from the feather hands; and mature fruits picked by the feather hands are collected into the fruit-collecting box through the fruit collecting plate. The picking device provided by the invention can replace manual picking, has high picking efficiency, good quality and low fruit breakage rate, can adapt to different terrains and different wolfberry crown diameters, and has wide application range.

The invention provides an exercise bicycle switch blade resistance regulating mechanism, which comprises a fixed mount, a regulation rod and a stay wire with a casing pipe, wherein the middle of the regulation rod is in rotation connection with the fixed mount; the lower end of the regulation rod is provided with a first hook; the end part of the stay wire is connected with the first hook; the fixed mount is also provided with a second hook; the casing pipe of the stay wire is connected and locked with the second hook; one surface, which is near the fixed mount, of the regulation rod is provided with spacing bulges; the fixed mount is provided with a plurality of spacing grooves matched with the spacing bulges; when the regulation rod rotates, the spacing bulges are embedded into one of the spacing grooves. The exercise bicycle switch blade resistance regulating mechanism has the advantages of high safety, simpleness and quickness in operation and high regulation accuracy.

The invention provides a vehicular limit gemel, which comprises a gemel shaft, a gemel fixing hinge fixedly connected with a vehicular body, a gemel movable hinge fixedly connected with a vehicular door, a spring, a fixing sleeve, a movable plate and a ball, wherein the gemel fixing hinge is fixedly connected with the gemel shaft; the gemel movable hinge is rotationally connected with the gemel shaft; the movable plate, the fixing sleeve and the spring are arranged sequentially along the axial direction of the gemel shaft; the movable plate is fixedly connected with the gemel movable hinge; the fixing sleeve is fixedly connected with the gemel shaft; the spring is sleeved on the gemel shaft and squeezes the fixing sleeve towards the movable plate; at least one spherical pit is formed on the movable plate; at least one arc-shaped groove corresponding to the spherical pit is formed on the fixing sleeve; and the ball is positioned between the spherical pit and the arc-shaped groove. The vehicular limit gemel has a compact structure, and can enhance the flexibility of vehicular arrangement.

The invention discloses a multifunctional exercise bike, comprising a handlebar, a seat cushion, a flywheel, a pedal and a body, as well as a magnetic resistance adjustment system, a water resistance adjustment system and a locking mechanism. The seat cushion and the body pass through a first elastic component Connection, through the reluctance adjustment system, the resistance of the exercise bike is initially adjusted by the user's own body weight; the locking mechanism is set so that when the user steps on the switch on the pedal, the reluctance adjustment system is locked to prevent the user from adjusting the riding. The sudden change of resistance during posture causes danger; a water resistance adjustment system is set up, so that the exercise bike can automatically adjust the water resistance according to the speed of the user's pedal rotation, so that the water resistance can be adjusted with the user's physical strength.

The invention relates to the technical field of a control valve and specifically discloses an automobile engine oil control valve. In comparison with an engine oil control valve of the prior art, the automobile engine oil control valve disclosed by the invention is capable of realizing sealing by virtue of a sealing sleeve, reducing the surface machining precision and assembly precision of a valve core and a valve body and lowering the production cost; an elastic part for providing pre-tightening force is arranged between the sealing sleeve and a sealing nut; the pre-tightening force can be adjusted by rotating the sealing nut so as to adjust the resistance in the motion process of the valve core; after the sealing sleeve is slightly abraded, the sealing nut can be rotated to press down the sealing sleeve so as to make the sealing sleeve again play a sealing effect, so the service life of the engine oil control valve is prolonged, and the frequency for replacing the engine oil control valve is reduced; the sealing sleeve can just be replaced even after being abraded seriously; in comparison with the engine oil control valve, which is replaced directly, of the prior art, the automobile engine oil control valve disclosed by the invention is lower in replacement cost.
