Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , a new type of hinge pin installation device, including a bottom plate 1, a pluggable moving plate 2 is arranged above the bottom plate 1, a through slot 3 is opened at the top of the moving plate 2, fixed slots 4 communicating with each other are opened on the left and right sides of the inner wall of the through slot 3, and a movable limiting roller 5 is arranged inside the fixed slot 4.

[0021] It also includes two electric push rods 6 which are respectively installed on the left and right sides of the moving plate 2. One end of the electric push rod 6 close to the fixed slot 4 penetrates through the fixed slot 4 and extends into it. A moving shell 7 is fixedly connected to the output end of the electric push rod 6. The surface of the moving shell 7 is in sliding contact with the inner wall of the fixed slot 4. An adjusting block 8 is arranged inside the moving shell 7. The surface of the adjusting block 8 is in sliding contact with the inner wall of the moving shell 7. Two positioning rods 9 are fixedly connected to the inner wall of the moving shell 7. One end of the positioning rod 9 close to the adjusting block 8 penetrates through the adjusting block 8 and extends to the outside of it and is fixedly connected to a stop block 10. One side of the stop block 10 close to the adjusting block 8 is in contact with the adjusting block 8. A buffer spring 11 is sleeved on the surface of the positioning rod 9. One side of the limiting roller 5 close to the adjusting block 8 is fixedly connected to the adjusting block 8.

[0022] A support plate 12 is fixedly connected to the left side of the top of the bottom plate 1. A fixing plate 13 is fixedly connected to the top of the support plate 12. A cylinder 14 is fixedly connected to the bottom of the fixing plate 13. A movable plate 15 is fixedly connected to the bottom of the cylinder 14. A connecting block 16 is fixedly connected to the bottom of the movable plate 15. A pressing head 17 is fixedly connected to the bottom of the connecting block 16. Two baffle plates 18 are arranged on the top of the movable plate 15. The bottom of the baffle plate 18 is in contact with the top of the movable plate 15. A mounting block 19 is fixedly connected to the bottom of the baffle plate 18. The bottom of the mounting block 19 penetrates through the movable plate 15 and extends to the outside of it.

[0023] Furthermore, by providing a limiting roller 5 and a buffer spring 11, the limiting roller 5 has a certain contraction effect. When the limiting roller 5 squeezes and fixes the hinge pin, the hinge pin can also move downward through the squeezing force of the pressure head 17. When the hinge pin moves downward, the limiting roller 5 can roll on the hinge pin.

[0024] Furthermore, the electric push rod 6 drives the limiting roller 5 to squeeze and fix the hinge pin in the through groove 3. As long as it is ensured that the hinge pin does not deviate or shake when it moves downward, there is no need to generate a large squeezing force on the hinge pin. After the limiting roller 5 squeezes and fixes the hinge pin, the buffer spring 11 still has a certain telescopic force, which facilitates the movement of the limiting roller 5 due to the downward movement of the hinge pin in the later stage.

[0025] Furthermore, a mounting plate 25 is fixedly connected to the bottom of the mounting block 19, and the side of the mounting plate 25 close to the movable plate 2 is in contact with the movable plate 2. A slot 26 is provided at the bottom of the mounting plate 25, and a block 27 is fixedly connected to the top of the movable plate 2 and corresponding to the position of the slot 26. The top of the block 27 passes through the slot 26 and extends to the inside to contact with the inner wall of the slot 26. A fastening bolt 28 threadedly connected to the block 27 is provided on the top of the mounting plate 25. By arranging the mounting plate 25, the slot 26, the block 27 and the fastening bolt 28, it is convenient to disassemble the movable plate 2 and to maintain and repair the structure on the movable plate 2.

[0026] Specifically, the fastening bolts 28 are loosened, and then the movable plate 2 is pulled downward, and the movable plate 2 drives the clamping block 27 to move downward, so that the clamping block 27 and the clamping slot 26 are separated, and the movable plate 2 can be removed.

[0027] A placement shell 20 is fixedly connected to the top of the bottom plate 1, and a movable block 21 is arranged inside the placement shell 20. The surface of the movable block 21 contacts the inner wall of the placement shell 20, and two fixed rods 22 are fixedly connected to the bottom of the inner wall of the placement shell 20. The top of the fixed rod 22 passes through the movable block 21 and extends to the outside to be fixedly connected to the top of the inner wall of the placement shell 20. A connecting spring 23 is sleeved on the surface of the fixed rod 22, and a plug 24 is fixedly connected to the top of the movable block 21 and the position corresponding to the pressure head 17.

[0028] Through the mutual cooperation of the moving plate 2, the through groove 3, the fixed groove 4, the limiting roller 5, the electric push rod 6, the moving shell 7, the adjusting block 8, the positioning rod 9, the stop block 10, the buffer spring 11, the support plate 12, the fixed plate 13, the cylinder 14, the movable plate 15, the connecting block 16, the pressing head 17, the baffle plate 18, the mounting block 19, the placing shell 20, the movable block 21, the fixed rod 22, the connecting spring 23 and the plug 24, a novel hinge pin installation device is realized, thereby ensuring the stability of the hinge pin during installation, avoiding affecting the quality of installing the hinge pin into the hinge, and improving the practicability.

[0029] During use, the hinge is placed on the top of the placing shell 20, so that the plug 24 passes through the pin hole where the hinge pin needs to be installed on the hinge, and then the hinge pin is inserted into the through groove 3 from top to bottom, as Figure 3 shown in the state. Then, the electric push rod 6 is started. The electric push rod 6 drives the limiting roller 5 to move close to the hinge pin through the moving shell 7, so that the limiting roller 5 moves into the interior of the through groove 3, and the hinge pin is squeezed and fixed by the limiting roller 5. Then, the cylinder 14 is started. The cylinder 14 drives the moving plate 2 to move downward through the movable plate 15, so that the moving plate 2 drives the hinge pin to move downward, making the bottom end of the hinge pin contact the top end of the plug 24. At this time, the movable plate 15 is still moving downward. The movable plate 15 slides downward on the surface of the mounting block 19, and the movable plate 15 drives the pressing head 17 to move downward. When the pressing head 17 contacts the top end of the hinge pin, the pressing head 17 drives the hinge pin to move downward, making the bottom of the moving plate 2 contact the top of the hinge. The moving plate 2 plays the role of pressing and limiting the hinge. Since the shape of the hinge pin is T-shaped, when the hinge pin moves downward, the hinge pin drives the limiting roller 5 to move close to the moving shell 7. The limiting roller 5 squeezes the buffer spring 11 through the adjusting block 8 to move, so that the hinge pin moves downward into the pin hole of the hinge. At the same time, the hinge pin drives the plug 24 to move downward. The plug 24 squeezes the connecting spring 23 through the movable block 21 to move, so that the plug 25 moves into the interior of the placing shell 20, and the hinge pin is completely inserted into the hinge to complete the installation.
