Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Reference Figure 1 - Figure 5 , an embodiment provided by the utility model: an ESD assembly limiter, comprising a table leg 3, a fixing component is provided inside the table leg 3, and a height adjustment component is provided outside the table leg 3;
[0034] The height adjustment assembly includes a hollow shell 2, a plurality of plug blocks 9 are fixedly connected to one side of the hollow shell 2, a rack 6 is slidably connected inside the hollow shell 2, a pull rod 7 is fixedly connected to one side of the rack 6, a spring 8 is sleeved on the outside of the pull rod 7, a tooth block 4 is slidably connected inside the hollow shell 2, a connecting column 5 is fixedly connected to one side of the tooth block 4, and a limiting assembly is provided on the end of the connecting column 5 away from the tooth block 4. The table leg 3 serves as the main supporting part of the table and is used to carry the internal fixed assembly and the external height adjustment assembly. The hollow shell 2 is the basis of the height adjustment assembly and carries various components inside. The plug block 9 is used to be inserted into the inside of the table leg 3. Whether the rack 6 is engaged with the tooth block 4 controls whether the tooth block 4 can slide inside the hollow shell 2. The pull rod 7 is used to pull the rack 6 to control whether the rack 6 is engaged with the tooth block 4. The spring 8 is used to ensure that the rack 6 and the tooth block 4 are tightly engaged in the absence of external force.
[0035] Reference Figure 4 and Figure 5 The fixing assembly includes a shell 10, which is fixedly connected to the inside of the table leg 3. A slide 16 is slidably connected to the inside of the shell 10. A circular column 11 is fixedly connected to one side of the slide 16. Both ends of the other side of the slide 16 are rotatably connected to a shaft 15. The shaft 15 is rotatably connected to the end away from the slide 16 with a latch 14. A limit plate 17 is fixedly connected to the inside of the shell 10. A sliding column 12 is fixedly connected to one side of the limit plate 17. A spring 13 is provided on the outside of the sliding column 12. The plug 9 is inserted into the inside of the table leg 3. The latch 14 is inserted into the inside of the plug block 9, and the shell 10 is used to carry the various components inside it to ensure normal operation. The slide 16 controls the rotation of the rotating shaft 15 under the push of the circular column 11, thereby controlling the movement of the latch 14. The spring 2 13 is used to ensure that the slide 16 will be close to the inner wall of the shell 10 when there is no external force, thereby ensuring that the latch 14 will not move. The limit plate 17 and the sliding column 12 work together to limit the slide 16. The latch 14 is used to fix the plug block 9 and the table leg 3.
[0036] Reference Figure 1 - Figure 4 The limit assembly includes a limit hook 1, one end of the connecting column 5 passes through the hollow shell 2 and is fixedly connected to the limit hook 1, one side of the limit hook 1 is slidably connected to the outside of the hollow shell 2. The limit hook 1 is used to limit and fix the table leg 3, and the connecting column 5 is used to connect the limit hook 1 with the tooth block 4, so that the limit hook 1 can also move when the tooth block 4 can move.
[0037] Reference Figure 1 - Figure 3 One end of the spring 8 is fixedly connected to one side of the rack 6, and the other end of the spring 8 is fixedly connected to the inner wall of the hollow shell 2. The spring 8 is used to tightly engage the rack 6 with the tooth block 4 in the absence of external force to ensure the stability of the limit hook 1.
[0038] Reference Figure 3 The pull rod 7 is fixedly connected to one end away from the rack 6 with a pull disc, the rack 6 is engaged with the tooth block 4, and the pull disc is used to facilitate pulling the pull rod 7.
[0039] Reference Figure 5 The sliding column 12 passes through the slide plate 16 and is slidably connected to the inside of the circular column 11. The latch 14 is slidably connected to the inner wall of the shell 10. The sliding column 12 is used to limit the circular column 11.
[0040] Reference Figure 1 - Figure 5 One end of the second spring 13 is fixedly connected to one side of the limit plate 17, and the other side of the second spring 13 is fixedly connected to one side of the slide 16. The second spring 13 is used to ensure that the pin 14 is tightly inserted into the plug block 9 in the absence of external force, thereby ensuring the fixation between the hollow shell 2 and the table leg 3.
[0041] Working principle: When the height of the limit hook 1 needs to be adjusted, pull the pull rod 7, the rack 6 will slide in the hollow shell 2, and the spring 18 will be gradually compressed. When the rack 6 and the tooth block 4 are not engaged, the tooth block 4 can move up and down in the hollow shell 2, thereby achieving the height adjustment of the limit hook 1. When it is adjusted to the appropriate position, release the pull rod 7. Under the action of the spring 18, the rack 6 and the tooth block 4 will re-engage, and the height adjustment of the limit hook 1 is completed. It effectively improves the practicality of the limit hook 1 and improves work efficiency. When it is necessary to remove the device from the table leg 3 When the table leg 3 is removed, the circular column 11 can be pushed to make the slide plate 16 slide inside the shell 10. Then the spring 2 13 is compressed, the sliding column 12 slides in the circular column 11, and the rotating shaft 15 rotates. Therefore, the pin 14 gradually moves closer to the shell 10 until the pin 14 is pulled out from the plug block 9. The whole device can be removed from the table leg 3. When it needs to be installed, it is only necessary to reinsert the plug block 9 into the table leg 3 and then loosen the circular column 11. Under the action of the spring 2 13, the pin 14 will be reinsert into the plug block 9, which facilitates the installation and disassembly of the whole device and improves work efficiency.
