[0018] like Figure 1-4As shown, an elevator car convenient for unloading comprises a load-bearing bottom frame 1, a car wall 2 is arranged on the upper surface of the load-bearing bottom frame 1, a car top 3 is arranged on the upper end of the car wall 2, a useful retaining frame 4 is arranged on the load-bearing bottom frame 1, the car wall 2 and the car top 3 are located inside the retaining frame 4, a mounting frame 5 is symmetrically arranged on the lower end of the load-bearing bottom frame 1, an electric telescopic rod 6 is symmetrically arranged on the mounting frame 5, a bottom plate 7 is arranged at the output end of the electric telescopic rod 6, side plates 8 are symmetrically arranged above the bottom plate 7, a limiting groove is arranged at one end of the two side plates 8 close to each other, a placing plate 9 is arranged between the two side plates 8, and both ends of the placing plate 9 are respectively provided with a A card slot is provided on the upper part of the bottom plate 7, and the placement plate 9 is located above the support plate 10. The side plate 8, the support plate 10 and the bottom plate 7 are connected by a support tube 11. An outlet 12 is provided on one side of the compartment wall 2, and a fixing block 13 with an internal thread is symmetrically provided on the lower surface of one end of the placement plate 9 away from the outlet 12 of the compartment wall 2. The support plate 10 is located between the fixing blocks 13 on both sides. A driving motor 14 is provided on the bottom plate 7, and a screw rod 15 threadedly connected to the fixing block 13 is provided at the output end of the driving motor 14. Two mounting seats 16 are provided on the bottom plate 7, and the screw rod 15 is rotatably connected to the two mounting seats 16.

[0019] The retaining frame 4 is used to ensure the stability of the compartment wall 2 and the compartment roof 3, and improve the anti-collision ability of the compartment wall 2 and the compartment roof 3; the compartment wall 2 is located on the load-bearing bottom frame 1, and the mounting frame 5 is fixed to the load-bearing bottom frame 1 by bolts or welding. The weight of people and goods in the car directly acts on the mounting frame 5; four groups of electric telescopic rods 6 are provided, and the four groups of electric telescopic rods 6 move synchronously. Through the synchronous movement of the four electric telescopic rods 6, the rise or fall of the bottom plate 7 can be controlled; the upper surfaces of the side plates 8 and the placement plates 9 can be used for people to stand, and when transporting goods by elevator, in order to facilitate the delivery of goods to the elevator, Outside, the elevator needs to be placed on the placement plate 9, and the width of the stacked goods should not be wider than the elevator exit 12, so as to prevent the goods from being unable to be transported to the outside of the elevator normally; the support plate 10 is used to support the placement plate 9, and with the cooperation of the support tube 11, the placement plate 9 can move along the upper surface of the support plate 10; when the drive motor 14 rotates, it can drive the screw rod 15 to rotate, and the rotation of the screw rod 15 is coordinated with the fixed block 13 with a threaded hole, and the cooperation of the limit groove on the side plate 8 and the card groove on the placement plate 9 can control the placement plate 9 to move linearly on the support plate 10.

[0020] Working principle: When transporting decoration materials through the elevator, first control the output ends of the four groups of electric telescopic rods 6 to move upward synchronously, push the bottom plate 7 to move upward, and then make the height of the lower surface of the placement plate 9 higher than the ground height of the elevator hall, so that the subsequent placement plate 9 can enter the elevator hall, and then control the drive motor 14 to rotate, and the drive motor 14 drives the screw rod 15 to rotate, and through the cooperation of the screw rod 15 and the fixed seat, the placement plate 9 is driven to move, and the placement plate 9 moves from the inside of the elevator to the outside of the elevator. When most of the placement plate 9 moves to the outside of the elevator, the drive motor 14 stops moving. Due to the large size of the placement plate 9 Part of it is located in the elevator hall, where the space is larger and the workable space is also larger. At this time, the goods can be conveniently placed on the placement plate 9, or the goods on the placement plate 9 can be taken away. When the placement plate 9 needs to enter the elevator, the driving motor 14 is first controlled to reverse, and the screw rod 15 is reversed to drive the placement plate 9 into the elevator. When the placement plate 9 completely enters the elevator, the driving motor 14 stops working, and then the output ends of the four groups of electric telescopic rods 6 are controlled to move downward to lower the position of the placement plate 9, so as to keep the upper surface of the placement plate 9 and the ground of the elevator hall at the same height as much as possible, so as to facilitate smooth entry and exit of the elevator.

[0021] Furthermore, universal balls 17 are evenly arranged on the upper surface of the bottom plate 7 , and the placement plate 9 is located on the upper part of the universal balls 17 . The universal balls 17 can reduce the friction between the placement plate 9 and the support plate 10 , and improve the smoothness of the movement of the placement plate 9 .

[0022] Furthermore, the lower surface of the outlet 12 end of the compartment wall 2, the upper surface of the placement plate 9 and the upper surface of the side plate 8 are all in the same plane, ensuring the safety of entering and exiting the elevator hall and the elevator to prevent false stepping and stumbling.

[0023] Furthermore, the width of the outlet 12 end of the compartment wall 2 is not less than the width of the placement plate 9 , so that the placement plate 9 can normally enter and exit from the outlet 12 end of the compartment wall 2 .

[0024] Furthermore, an oblique support rod 18 is provided between the retaining frame 4 and the load-bearing bottom frame 1 , and the oblique support rod 18 is used to increase the stability of the compartment wall 2 , the compartment roof 3 and the retaining frame 4 .

[0025] The placement board 9 in the device can be moved from the elevator to the elevator hall, and can also be moved from the elevator hall to the elevator. When the placement board 9 is moved to the elevator hall, the space around the placement board 9 is significantly increased relative to the space in the elevator, and the hindrance to personnel activities is reduced, which makes it convenient to neatly stack the decoration materials on the placement board 9 and also to unload the materials on the placement board 9. When the placement board 9 is located in the elevator hall, multiple people can carry the materials on the placement board 9 at the same time, which is convenient to use.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
