DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a cargo warehouse vehicle for preventing cargo from slipping, comprising two vehicle bodies 1, the two vehicle bodies 1 are connected by a screw structure, the screw structure comprises a ball screw 7 and a connecting sleeve 8, the outer ring of the ball screw 7 is threadedly connected with a ball nut, the ball nut is fixedly connected to the connecting sleeve 8, when the ball screw 7 rotates, the ball nut threadedly connected thereto can move in the direction where the ball screw 7 is located, and when the ball nut moves, it drives the connecting sleeve 8 fixedly connected thereto to connect. The ball screw 7 is movably connected to one vehicle body 1, and the connecting sleeve 8 is fixedly connected to the other vehicle body 1. By setting the screw structure, the distance between the two vehicle bodies 1 can be changed. And when the two vehicle bodies are connected by multiple screw structures, two adjacent ball screws 7 are transmitted by a synchronous belt 13, and the user only needs to rotate one ball screw 7 to make the other ball screws 7 on the cargo warehouse vehicle rotate synchronously, so as to facilitate the adjustment of the distance between the two vehicle bodies 1.

[0023] A blocking rod 9 is provided between the two car bodies 1. A blocking rod 9 is evenly fixed on the inner side of one car body 1, and another blocking rod 9 is evenly fixed on the inner side of the other car body 1. The blocking rod 9 and the other blocking rod 9 are alternately arranged, and the outer diameter of the blocking rod 9 is the same as the outer diameter of the connecting sleeve 8. By setting the blocking rod 9, the goods can be intercepted, which is convenient for the car body 1 to support and limit the goods.

[0024] A supporting platform 2 is provided on the front side of the bottom of the vehicle body 1, a running wheel 4 is provided on the rear side of the bottom of the vehicle body 1, a handle 3 is provided at the other end of the vehicle body 1, and the distance between the side of the running wheel 4 away from the supporting platform 2 and the vehicle body 1 is equal to the distance between the side of the handle 3 away from the supporting platform 2 and the vehicle body 1, that is, when the handle 3 and the running wheel 4 are in contact with the ground at the same time, the vehicle body 1 can be in a horizontal state.

[0025] A fixed structure is provided on the outside of a vehicle body 1, and the fixed structure includes a protective shell 5. The protective shell 5 is a hollow structure. An inlet and outlet 17 is provided on the side of the inner cavity of the protective shell 5 close to the supporting platform 2. A plurality of rotating rods 20 are evenly and movably connected from top to bottom in the inner cavity of the protective shell 5. A coil spring 21 is fixedly connected to the outer ring of the rotating rod 20. The other end of the coil spring is fixedly connected to one end of a strap 16. The strap 16 is wound around the coil spring 21, and the other end of the strap 16 extends to the outside of the protective shell 5 through the inlet and outlet 17. Through the arrangement of the coil spring 21 and the rotating rod 20, under the action of external force, the length of the strap 16 exposed outside the protective shell 5 can be changed, thereby releasing the restriction on the strap 16. Under the action of the rebound force of the coil spring 21, the strap 16 can be rewound around the coil spring 21 to realize automatic storage of the strap 16.

[0026] A group of rollers 18 are respectively provided at both ends of the inner cavity of the inlet and outlet 17, and the strap 16 passes through a group of rollers 18. Through the setting of the rollers 18, the rollers 18 can guide the strap 16, reduce the friction between the strap 16 and the protective shell 5, and extend the service life of the strap 16.

[0027] The other end of the strap 16 is fixedly connected to a handle 11, a pull ring is provided in the middle of the handle 11, and both ends of the handle 11 are provided with limit holes 10. A fixed shell 6 is provided on the outside of the other car body 1, and both ends of the fixed shell 6 away from the support platform 2 are fixed with limit posts 12, which are adapted to the limit holes 10. By setting the limit posts 12, the position of the handle 11 can be fixed by using the limit posts 12. And when the two car bodies 1 are connected by multiple screw rod structures, the fixed shell 6 blocks the synchronous belt 13, separates the synchronous belt 13 from the goods, and facilitates the adjustment of the width of the cargo warehouse.

[0028] A squeezing rod 19 is movably connected to one side of the inlet and outlet, and the squeezing rod 19 is located between the two sets of rollers 18. The squeezing rod 19 is fixedly connected to the protective shell 5 through the electric telescopic rod 14. The end of the output shaft of the electric telescopic rod 14 is fixedly connected to the squeezing rod 19, and the other end of the electric telescopic rod 14 is fixedly connected to the protective shell 5. Through the setting of the electric telescopic rod 14, the extension and retraction of the electric telescopic rod 14 can change the position of the squeezing rod 19 fixedly connected thereto. The squeezing rod 19 can press the strap 16 to fix the exposed length of the strap 16. When the warehouse truck is in use, the strap 16 can be used to tie up the goods to prevent the goods from slipping during transportation. The setting of multiple straps 16 increases the contact area between the strap 16 and the goods, which can improve the cargo tying effect. In some embodiments of the present application, the height value of the squeezing rod 19 is the same as the height value of the inlet and outlet.

[0029] To sum up: before using the cargo storage truck for preventing cargo from slipping, the user rotates the ball screw 7 according to the needs. When the ball screw 7 rotates, the ball nut threadedly connected to the ball screw 7 moves in the direction of the ball screw 7. When the ball nut moves, it drives the connecting sleeve 8 fixedly connected to it to move. The connecting sleeve 8 drives the car body 1 fixedly connected to it to move, and the distance between the two car bodies 1 can be changed until the width of the cargo storage truck meets the needs. After the goods are loaded on the cargo warehouse vehicle, the user pulls the handle 11 outward, and the handle 11 drives the strap 16 fixedly connected thereto to move, and the length of the strap 16 exposed outside changes. The user drives the strap 16 to move through the handle 11 so that the strap 16 contacts the side of the goods away from the material blocking rod 9. After the position of the handle 11 is fixed by the limiting column 12, under the action of the rebound force of the coil spring 21, the strap 16 fits tightly against the goods, and the electric telescopic rod 14 extends, and the electric telescopic rod 14 drives the extrusion rod 19 fixedly connected thereto to move until the extrusion rod 19 fits tightly against the strap 16. At this time, the extrusion rod 19 limits the strap 16 so that the length of the strap 16 exposed outside does not exceed 100%. The strap 16 can be used to quickly bundle the goods, so as to prevent the goods from slipping during transportation and facilitate the transportation of the goods. After the goods are moved to the designated position, the electric telescopic rod 14 contracts to release the restriction of the squeezing rod 19 on the strap 16. The user pulls the handle 11 outward to separate the handle 11 from the limiting column 12, and then separates the strap 16 from the goods. The user moves the handle 11 to gradually approach the protective shell 5. During the movement of the handle 11, the resilience of the coil spring 21 causes the strap 16 to automatically wrap around the coil spring 21 until the handle 11 contacts the protective shell 5, and the strap 16 is completely received in the protective shell 5, so as to prevent the fixed structure from affecting the handling of the goods.
