A sleeve 1321 with a hollow interior and two open ends is arranged on the front clamping plate 132, the length direction of the sleeve 1321 is the longitudinal direction relative to the turning plate 120, and the inner diameter of the sleeve 1321 is larger than the outer diameter of the inserted rod 1341. The push plate 1342 is fixed at one end of the insert rod 1341 and located right above the flap 120, and the other end of the insert rod 1341 extends to the outside of the flap 120 through the sleeve 1321. Through the arrangement of the sleeve 1321 and the plug 134, a worker can conveniently push the plug 134, and the sleeve 1321 limits the plug 134 to generate transverse deviation when moving longitudinally relative to the turning plate 120, so that the smoothness of pushing the plug 134 is ensured. The design of the plug 134 structure can also facilitate the simultaneous connection of the two linkage plates 133.

The push plate 1342 and the ball nut 1343 are respectively installed at both ends of the insert rod 1341, and the push plate 1342 and the ball nut 1343 are respectively located at both ends of the sleeve 1321. The width of the push plate 1342 is greater than the inner diameter of the sleeve 1321, and the width of the ball nut 1343 is greater than the inner diameter of the sleeve 1321; when the plug 134 is pushed, the ball nut 1343 is mounted at one end of the push rod, so that the ball nut 1343 does not enter the sleeve 1321, and the plug 134 does not endlessly move longitudinally relative to the flap 120. The structural design of the plug 134 can ensure the stability of the whole structure, the plug 134 can not fall off in the using process, and workers do not need to consider how much force to push the plug 134 when using, so that the use is more convenient. In addition, the inserting rod 1341 is provided with external threads which are matched with the internal threads of the ball nut 1343, so that the ball nut 1343 is convenient to assemble and disassemble, and the plug 134 is also convenient to install on the turning plate 120 and the front clamping plate 132; the end of the plug 134 remote from the push plate 1342 is passed through the sleeve 1321 and then the ball nut 1343 is tightened onto the end of the plug 134.

In the initial state, the turning plate 120 and the locking mechanism 130 fall down to a certain position due to the self weight; in this position, the side wall of the mounting hole 112 abuts against the fastening member 123, so that the fastening member 123 is at a certain level. The flap 120 and the locking mechanism 130 are also at this level and the trolley is not moved onto the pallet. The flap 120 is located at a lower horizontal position, at this time, the limiting portion 1311 is not inserted into the limiting hole 111, and one end of the limiting portion 1311 close to the limiting hole 111 is not pressed by the longitudinal beam 1172, so that the spring 136 is in an extended state, and one end of the limiting portion 1311 protrudes out of the accommodating groove 1351.

When the logistics vehicle needs to be locked by the tray, the worker pushes the logistics vehicle right above the tray, and the wheels on two sides of the logistics vehicle slide along the first rail 113 and the second rail 1192 respectively. When the wheels of the logistics cart contact the tailgate 114, or the logistics cart contacts the stop 115, it is indicated that the logistics cart is moving into position. The worker then lifts flap 120 by hand, or lifts flap 120 by foot, or lifts flap 120 using other mechanisms. As the flap 120 moves upward, the synchronous locking mechanism 130 is raised. During the ascending process, one end of the limiting part 1311 is pressed by the longitudinal beam 1172, the limiting part 1311 retracts into the accommodating groove 1351 relative to the initial state, and the limiting part 1311 compresses the spring 136 and contracts the spring 136 when retracting. The turning plate 120 continuously moves upward, when the turning plate moves to the position where the position-limiting portion 1311 is aligned with the position-limiting hole 111, the position-limiting portion 1311 is not pressed by the side of the bottom frame 110 due to the position-limiting hole 111, and the position-limiting portion 1311 is inserted into the position-limiting hole 111 under the resilient force of the spring 136. At this moment, the turning plate 120 cannot continuously ascend or descend, the turning plate 120 and the front clamping plate 132 are located at the positions with higher heights, and the front clamping plate 132 can clamp the logistics vehicle to lock the logistics vehicle and prevent the logistics vehicle from moving randomly.

When it is desired to unlock the lock, the operator pushes the plug 134 by hand or foot, or other mechanism is provided to push the plug 134, and the plug 134 moves longitudinally relative to the flap 120. The plug 134 drives the linkage plate 133 to rotate, the linkage plate 133 drives the connecting part 1312 to move in the direction away from the limiting hole 111 when rotating, and the limiting part 1311 and the connecting part 1312 move synchronously; the stopper 1311 is pulled out of the stopper hole 111. After the limiting part 1311 is pulled out, the flap 120 and the locking mechanism 130 move downward to the initial state under the action of gravity because there is no limitation of the limiting member 131 by the limiting hole 111. At this time, the front card 132 also synchronously descends to the initial state, so that the front card 132 no longer clamps the logistics vehicle, and the logistics vehicle is unlocked and can be moved away from the tray.

When the logistics vehicle tray 100 is used for locking the logistics vehicle, only the turning plate 120 needs to be lifted; when the locking is released, the plug 134 is pushed. Therefore, the logistics vehicle tray 100 is very convenient to lock or unlock, and has strong practicability and simpler overall structure.

The locking mechanism 130 is arranged in such a way, the locking and unlocking can be realized by utilizing the self elasticity of the spring 136, the operation is convenient, and the structure is simple; and turn over board 120 and preceding cardboard 132 and rise to a take the altitude after, the spacing hole 111 that the underframe 110 was seted up can restrict spacing portion 1311, prevents to continue to rise, guarantees overall structure's stability, and the staff also can judge whether accomplish the locking very directly perceivedly when using.

As can be seen from the foregoing description, the stop portion 1311 is pressed by the longitudinal beam 1172 during the raising process. In the embodiment, the inclined surface 1314 is arranged at one end of the limiting part 1311, and the longitudinal beam 1172 extrudes the limiting part 1311 and is specifically contacted with the inclined surface 1314, so that the inclined surface 1314 is obliquely extended towards the side where the limiting hole 111 is located from top to bottom, when the limiting part 1311 is extruded, the extrusion force is gradually increased, the spring 136 is gradually compressed, and the limiting part 1311 is gradually contracted towards the inside of the accommodating groove 1351; the staff is more laborsaving, more smooth and easy when lifting the turnover plate 120.
