The left end outer wall of the base 1 contacts the turntable 2, and the right end of the turntable 2 is fixedly connected to a bidirectional screw rod 3. The bidirectional screw rod 3 is composed of a shaft with two sections of threads with different rotation directions, one section of the thread is right-handed and the other section is left-handed, which can allow the two sets of connecting blocks 4 to move closer to or separate from each other. The outer wall of the bidirectional screw rod 3 is provided with a connecting block 4, and the middle of the connecting block 4 matches the outer wall thread of the bidirectional screw rod 3, which can meet the requirements of the connecting block 4 to move laterally along the outer wall of the bidirectional screw rod 3, and the bottom end of the connecting block 4 rotates to connect It is connected to an auxiliary wheel 5, which can reduce the friction between the connecting seat 6 and the connecting block 4 on the base 1.

The movable shaft 7 can be moved vertically by the driving device to meet subsequent transportation needs. The existing technology will not be described in detail here. The inner side wall of the connecting seat 6 is slidably connected to the movable shaft 7, and the right end of the movable shaft 7 is fixedly connected to a fixed plate 8. The fixed plate 8 mainly connects or supports the sleeve plate 9 and the movable plate 10. There are two groups of fixed plates 8. The outer walls of the two groups of fixed plates 8 are fixedly connected to the sleeve plate 9 and the movable plate 10 respectively. The sleeve plate 9 and the movable plate 10 are the existing cargo supporting parts. The left end of the turntable 2 is fixedly connected to the positioning sleeve 11. The inner wall of the positioning sleeve 11 is provided with a limiting mechanism, and the inner wall of the base 1 is provided with a contact component.
[0032] Reference Figure 1 、 Figure 4 and Figure 5The contact assembly includes a guide column 14, which can guide the bottom plate 18 vertically. The inner wall of the left end of the guide column 14 is elastically connected to the extrusion plate 16 through a positioning spring 15. The extrusion plate 16 is inclined. When the inclined surface is squeezed, the extrusion plate 16 will slide along the inner wall of the guide column 14. The left end of the extrusion plate 16 is fixedly connected to a pull rod 17, which can be used to move the extrusion plate 16 laterally on the inner wall of the guide column 14 through the pull rod 17. The bottom end of the guide column 14 is fixedly connected to the bottom plate 18. The bottom end of the bottom plate 18 is made of rubber material, which can increase the friction with the ground to ensure the stability of the device. The guide column 14 passes through and is slidably connected to the inner wall of the base 1. The inner wall of the left end of the guide column 14 is fixedly connected to one end of the positioning spring 15. When the extrusion plate 16 moves to the left, it compresses the positioning spring 15, and the device is restored. When the guide post 14 is in the correct position, the elastic force of the positioning spring 15 is used to reset the extrusion plate 16. The other end of the positioning spring 15 is fixedly connected to the left end of the extrusion plate 16. The extrusion plate 16 passes through and is slidably connected to the inner wall of the guide column 14. A notch corresponding to the extrusion plate 16 is provided on the guide column 14, allowing the extrusion plate 16 to slide along the notch. The pull rod 17 passes through and is slidably connected to the inner wall of the guide column 14. The bottom end of the pull rod 17 contacts the top of the base 1. When the extrusion plate 16 is plugged into the notch on the base 1, the pull rod 17 contacts the base 1. The pull rod 17 blocks the guide column 14 from continuing to move downward. The extrusion plate 16 is plugged into the inner wall of the base 1. A notch corresponding to the extrusion plate 16 is provided on the base 1, allowing the extrusion plate 16 to be plugged into the notch to limit the entire guide column 14 and the bottom plate 18 in one direction.
[0033] Reference Figure 1-Figure 3 The limiting mechanism includes a cannula 13, which passes through and is slidably connected to the inner wall of the positioning sleeve 11. The positioning sleeve 11 mainly supports and connects the cannula 13. The inner side wall of the cannula 13 is elastically connected to the positioning sleeve 11 through a return spring 12. The inner side wall of the cannula 13 is fixedly connected to one end of the return spring 12. When the cannula 13 moves to the left, the return spring 12 is stretched. When resetting, the cannula 13 is reset by the elastic force of the return spring 12. The other end of the return spring 12 is fixedly connected to the left end of the positioning sleeve 11. The cannula 13 passes through and is slidably connected to the rotating On the inner wall of the disk 2, the insert tube 13 is inserted into the outer wall of the left end of the base 1. The outer wall of the left end of the base 1 is provided with a circle of notches corresponding to the insert tube 13, which allows the insert tube 13 to be inserted therewith to ensure the stability of the bidirectional screw rod 3. The connecting block 4 is slidably connected to the inner wall of the base 1. A notch is provided on the base 1, which allows the connecting block 4 to move laterally along the notch of the base 1. The connecting seat 6 is slidably connected to the top of the base 1. The bottom end of the auxiliary wheel 5 contacts the inner wall of the top end of the base 1. The sleeve plate 9 and the movable plate 10 slide relative to each other, and the bidirectional screw rod 3 passes through and is rotatably connected to the inner wall of the base 1.
[0034] Working principle: First, when it is necessary to match the conveyor platforms with different diameters, just hold the positioning sleeve 11 with your hand and move it to the left to squeeze the cannula 13 with your hand and move it to the left. At this time, the reset spring 12 is in a compressed state, so that the right end of the cannula 13 is separated from the outer wall groove of the base 1. Then rotate the positioning sleeve 11 to rotate the turntable 2 and the two-way screw 3, so that the two sets of connecting blocks 4 bring the connecting seat 6, the movable shaft 7 and the fixed plate 8 closer to each other, so that the movable plate 10 and the sleeve plate 9 on the fixed plate 8 slide with each other, and adjust according to the conveyor platforms with different diameters. When limiting is required, just loosen the positioning sleeve 11 with your hand, and use the reverse elastic force of the reset spring 12 to reset the cannula 13 to the right, so that the right end of the cannula 13 is plugged into the outer wall of the base 1. When adjusting the distance between the two sets of connecting seats 6 again, just follow the above steps.
[0035] When the device is in use, it is only necessary to step on the guide column 14 with the foot so that the inclined surface of the extrusion plate 16 is squeezed by the top of the base 1, and the extrusion plate 16 moves to the left with the pull rod 17. At this time, the positioning spring 15 is in a compressed state. When the extrusion plate 16 coincides with the notch of the base 1, the reverse elastic force of the positioning spring 15 is used to move the extrusion plate 16 to the right, and the extrusion plate 16 is plugged into the inner wall of the base 1. When the guide column 14 moves downward, the guide column 14 will move the bottom plate 18 downward, allowing the bottom plate 18 to contact the ground to increase the contact area. When the entire device needs to be moved, it is only necessary to move the pull rod 17 by hand to separate the extrusion plate 16 and the notch of the base 1, and then move the guide column 14 upward with the bottom plate 18 to the initial state.
