[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A mobile phone self-service rental and return terminal includes a rental terminal body 7 and a base 1 fixed at its lower end. The base 1 has a storage slot, and the bottom of the storage slot has four annularly distributed openings. Lifting blocks 8 are slidably inserted into the inner sidewalls of the openings to drive universal wheels 9 to rise and fall. The lower end of the lifting block 8 has a groove, and the top of the groove is rotatably connected to the universal wheel 9 for easy overall movement. The lower end of the universal wheel 9 passes through the groove.

[0021] In this embodiment, a limiting block 14 is fixedly connected to the outer wall of the lifting block 8 to limit the lifting and lowering stroke of the lifting block 8 in conjunction with the limiting groove. The inner wall of the storage groove is provided with a limiting groove corresponding to the limiting block 14. The end of the limiting block 14 away from the lifting block 8 slides into the limiting groove. The outer wall of the limiting block 14 is provided with an arc-shaped groove. A ball is rolledly connected to the inner wall of the arc-shaped groove to reduce the resistance of the limiting block 14 when it rises and falls with the lifting block 8. The ball passes through the arc-shaped groove. A guide rod 10 is slidably inserted into the upper end of the lifting block 8 to guide the lifting block 8. The upper end of the guide rod 10 is fixedly connected to the inner top of the storage groove. The upper ends of the guide rod 10 and the lead screw 11 are both fitted with fixing rings to improve the firmness of the lead screw 11 and the guide rod 10. The upper end of the fixing ring is fixedly connected to the inner top of the storage groove. The lead screw 11 and the fixing ring are rotatably connected. The guide rod 10 and the fixing ring are fixedly connected.

[0022] In this embodiment, a lead screw 11 is inserted into the upper end of the lifting block 8 to drive the lifting block 8 to rise and fall. The lead screw 11 and the lifting block 8 are connected by a thread. The upper end of the lead screw 11 is rotatably connected to the inner top of the storage slot. A second gear 12 is fixedly sleeved on the upper end of the lead screw 11 to drive the lead screw 11 to rotate. A first gear 6 is provided near the center of the storage slot to mesh with the second gear 12 and to drive the second gear 12 to rotate. A vertically arranged connecting column 4 is fixedly connected inside the first gear 6 to drive the first gear 6 to rotate. The upper and lower ends of the connecting column 4 pass through the first gear 6 and are rotatably connected to the inner sides of the storage slot. A support plate 5 is fixedly sleeved on the connecting column 4 to support the first gear 6. The upper end of the support plate 5 is fixedly connected to the lower end of the first gear 6.

[0023] In this embodiment, a worm gear 3 is fixedly sleeved on the lower end of the connecting column 4 to drive the connecting column 4 to rotate. The helix angle of the worm 2 is smaller than the friction angle of the worm gear 3 and the worm 2, which serves to play a self-locking and anti-loosening role. A worm 2 that meshes with the worm gear 3 is arranged longitudinally in the storage slot to drive the worm gear 3 to rotate. One end of the worm 2 is rotatably connected to the inner side wall of the storage slot, and the other end of the worm 2 passes through the base 1 and is fixedly sleeved with a knob 13 to facilitate the user to rotate the worm 2. The worm 2 and the base 1 are rotatably connected. A rubber strip is fixedly connected to the outer side wall of the knob 13 to play an anti-slip role.

[0024] In this embodiment, the worm gear 2 is first driven to rotate by manually rotating the knob 13. Then, the meshing mechanism between the worm gear 2 and the worm wheel 3 drives the connecting column 4 and the first gear 6 to rotate synchronously. The first gear 6 then drives four meshing second gears 12 to rotate. These second gears 12 further drive their respective lead screws 11 to rotate. The lead screws 11 drive the lifting block 8 to rise and fall through the meshing action of the threads (the rising and falling of the lifting block 8 is controlled by the forward and reverse rotation of the lead screw 11, which is controlled by the user rotating the worm gear 2). When the lifting block 8 falls, it pushes the universal wheel 9 to extend from the opening and contact the ground, thereby supporting the base 1. This allows the user to easily move the rental terminal body 7 through the universal wheel 9, improving the convenience of displacement. When no movement is needed, the universal wheel 9 can be retracted back into the opening by the upward movement of the lifting block 8 to prevent the rental terminal body 7 from shifting due to loosening.

[0025] As described above, the rental terminal body is an existing mature technology, and its working principle and internal structure are known to those skilled in the art. This application only utilizes its functions and does not improve its internal structure, therefore, it will not be described in detail.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
