Detailed Implementation
[0016] Example 1
[0017] like Figure 1 and Figure 2As shown, a shim for easy assembly includes a shim housing 1. A drive cavity 2 is formed at the top of the shim housing 1, and a screw 3 is installed inside the drive cavity 2. Both ends of the screw 3 are connected to mounting shafts 5, which rotatably connect to the shim housing 1. Insertion pins 4 are coaxially inserted at both ends of the screw 3, and the insertion pins 4 have the freedom to move along the axial direction of the screw 3. A rectangular groove 6 is formed at the end of the mounting shaft 5 near the screw 3, and the insertion pins 4 fit into the rectangular groove 6. A lower wedge block 7 is threaded onto the screw 3, and an upper wedge block 8 fits onto the top inclined surface of the lower wedge block 7. A cover plate 9 is detachably installed on the top of the shim housing 1, and a lifting column 10 slides through the cover plate 9. One end of the lifting column 10 is fixedly connected to the upper wedge block 8, and the other end is detachably connected to a support platform 11. The cover plate 9... The mounting base box 1 is connected by screws. One of the mounting shafts 5 extends from the mounting base box 1 and is connected to a nut. Rotating the nut drives the mounting shaft 5 to rotate, which in turn drives the screw rod 3 to rotate. This causes the lower wedge block 7 to move linearly along the axis of the screw rod 3. The lower wedge block 7 lifts the upper wedge block 8 upward or causes the upper wedge block 8 to move downward under its own weight, thus adjusting the support height of the support platform 11. The screw rod 3 is assembled onto the mounting shaft 5 through the cooperation of the plug post 4 and the rectangular groove 6. During assembly, the lower wedge block 7 is threaded onto the screw rod 3, and then the plug post 4 is moved into the screw rod 3. The two ends of the screw rod 3 are aligned with the two mounting shafts 5, and then the plug post 4 is inserted into the rectangular groove 6 of the mounting shaft 5 to complete the assembly. The assembly is simple and easy to disassemble. The screw rod and the lower wedge block can be replaced separately, reducing the later maintenance cost.
[0018] Example 2
[0019] Based on Example 1, such as Figure 1 As shown, a circular groove 19 is provided at the bottom of the support platform 11, and the top of the lifting column 10 is fitted into the circular groove 19. A countersunk hole 20 is provided at the top of the support platform 11, and the countersunk hole 20 is coaxially connected to the circular groove 19. A fastening screw 21 is provided in the circular groove 19, and the tail of the fastening screw 21 passes through the circular groove 19 and is threaded to the lifting column 10. Positioning is completed by the cooperation between the lifting column 10 and the circular groove 19. Then, the lifting column 10 and the support platform 11 are connected together by the fastening screw 21, so that the support platform 11 can be removed and replaced separately. Furthermore, the fastening screw 21 is hidden by the countersunk hole 20 to avoid interference between the fastening screw 21 and the supported equipment.
[0020] Example 3
[0021] Based on Example 2, such as Figure 1 and Figure 2As shown, both ends of the screw 3 are provided with mounting grooves 12, and springs 13 are installed in the mounting grooves 12. The plug-in post 4 is slidably disposed in the mounting groove 12. The two ends of the spring 13 are respectively connected to the plug-in post 4 and the screw 3. The mounting groove 12 includes a sliding groove 14 and a limiting groove 15 connected sequentially in the direction away from the mounting axis 5. The size of the limiting groove 15 is larger than the size of the sliding groove 14. The plug-in post 4 is slidably adapted to the sliding groove 14. One end of the plug-in post 4 extends into the limiting groove 15 and is fixedly connected to a limiting plate 16. The size of the limiting plate 16 is larger than the size of the sliding groove 14. The spring 13 is connected to the limiting plate 16. When the plug-in post 4 is inserted into the rectangular groove 6, the spring 13 is in a compressed state. Both ends of the screw 3 are provided with levers 17 on the side walls. The levers 17 are connected to the limiting plate 16. The levers 17 have the freedom to move along the axial direction of the screw 3. Both ends of the screw 3 are provided with strip grooves 18 on the side walls. The strip grooves 18 are connected to the mounting axis 15. The limiting groove 15 and the lever 17 are connected to the limiting plate 16 by sliding one end into the strip groove 18. To ensure that the lower wedge block 7 is fitted onto the screw 3, the lever 17 is completely located within the strip groove 18. This prevents interference with the lever 17 when installing or removing the lower wedge block 7. During assembly, a finger is inserted into the strip groove 18 to move the lever 17 closer to the center of the screw 3. This causes the lever 17 to move the limiting plate 16 and compress the spring 13. The limiting plate 16 then moves the insertion post 4 into the slide groove 14. The screw 3 is then aligned with the mounting shaft 5. Finally, the lever 17 is released, and the insertion post 4 is inserted into the rectangular groove 6 under the reaction force of the spring 13. Since the spring 13 is always compressed, the insertion post 4 is pressed tightly against the rectangular groove 6, improving the connection strength. During disassembly, the insertion post 4 is moved into the slide groove 14 using the same method. The operation is simple and convenient for assembly, facilitating future replacement and maintenance.
