[0009] Further, the output shaft of the motor is fixedly connected to one of the sprockets. Both edges at the top ends of the movable ladder are fixedly connected to the chain, and the two sprockets are meshed and driven by the chain.

[0010] Further, anti-slip structures are fixedly arranged on the surfaces of the steps inside the fixed ladder.

[0011] Further, the motor is used to drive the sprocket to rotate, and the sprocket drives the chain to drive the movable ladder to lift and lower.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] In a concealed type climbing device for an automobile container, a transmission member is provided. The movable ladder is fixedly installed on the transmission member. When the transmission member moves, it drives the movable ladder to move up and down synchronously. The transmission member includes a chain and sprockets at both ends of the chain. The motor drives the sprocket to rotate, and drives the movable ladder to lift and lower by driving the chain, so as to realize the lowering use or concealed storage of the movable ladder.

[0020] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects of the present utility model as follows.

[0021] Please refer toFigures 1 - 4 As shown in the figure, the purpose of this embodiment is to provide a retractable climbing device for a vehicle container, which includes a fixed ladder 1. On both sides of the fixed ladder 1, there are fixedly connected shells 2. The shells 2 are used to hide and store a movable ladder 4. At the upper ends of the shells 2, there are fixedly arranged top covers 3. Inside the shells 2, there is a movable ladder 4 movably arranged. Inside the shells 2, there is a transmission member, which is used to realize the up and down movement of the movable ladder 4. The movable ladder 4 is fixedly installed on the transmission member. When the transmission member moves, it drives the movable ladder 4 to move up and down.

[0022] The shell 2 is fixedly installed at the top edge of one side of the container. The shell 2 is composed of a metal frame. On both sides of the shell 2, there are opened rectangular troughs, which provide space for the movement of the movable ladder 4.

[0023] At the lower end of the left side of the top cover 3, there is a motor 21. The motor 21 is fixedly installed at the upper end inside the left rectangular trough. At the top of the motor 21, there is a dust-proof protective cover fixedly arranged.

[0024] The transmission member is arranged inside the rectangular trough, which is used to realize the protection and hidden storage of the transmission member. The transmission member includes a chain 22 and sprockets 23 at both ends of the chain 22. At the center of each sprocket 23, there is a fixed shaft 24 rotatably installed, and the other end of the fixed shaft 24 is fixedly installed on one side of the fixed ladder 1. At the horizontal position of the top sprocket 23 at the edge of the rectangular trough, there is a fixed limit block 25, which is used to block the movable ladder 4 and provide limit and shielding for it.

[0025] The output shaft of the motor 21 is fixedly connected to one of the sprockets 23. At both ends of the top edge of the movable ladder 4, they are both fixedly connected to the chain 22. The two sprockets 23 are meshed and driven by the chain 22. When the output shaft of the motor 21 rotates, it drives one of the sprockets 23 to rotate. Due to the transmission of the chain 22, it drives the other sprocket 23 to rotate synchronously, and drives the movable ladder 4 fixed on the chain 22 to move.

[0026] On the surface of each step inside the fixed ladder 1, there is a fixedly arranged anti-slip structure, and the anti-slip structure is preferably raised anti-slip particles, which are used to increase the friction force of the surface of each step.

[0027] The motor 21 is used to drive the sprocket 23 to rotate, and then drives the chain 22 to move through the rotation of the sprocket 23, and drives the movable ladder 4 to lift by driving the chain 22.

[0028] Working principle: When the motor 21 starts, it drives the transmission member, makes the chain 22 move, and makes the movable ladder 4 move downward. The movable ladder 4 stops when it reaches the lower end of the chain 22. Similarly, when the motor 21 rotates in the reverse direction, the movable ladder 4 moves upward and retracts.

[0029] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content without departing from the technical solution scope of the present utility model. However, as long as it does not depart from the technical solution content of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
