Description

Technical Field

[0001] This utility model relates to the field of antistatic equipment technology, and in particular to an antistatic device for safe production. Background Technology

[0002] Antistatic wrist straps are a common tool for protecting against static electricity. They mainly consist of a conductive elastic band, a snap fastener, a spring PU wire, a protective resistor, and a plug or alligator clip. Depending on their structure, antistatic wrist straps can be divided into corded wrist straps and cordless wrist straps. When using corded wrist straps, the alligator clip needs to be fixed to the ground point for antistatic protection.

[0003] When using antistatic wrist straps, the length of the wire between the alligator clip and the wrist strap is fixed. This limits the user's flexibility and makes it necessary to propose a safe antistatic device. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] The safety production anti-static device proposed according to this utility model includes a base, a support tube fixedly connected to the upper surface of the base, a slider slidably connected to the inner wall of the support tube, a cavity symmetrically opened inside the slider, a limit block slidably connected to the inner wall of each of the two cavities, a pull rope fixedly connected to one side of the outer wall of each of the two limit blocks, and one end of each pull rope extending through a hole to the outside of the slider and fixedly connected to a connecting rope.

[0006] One end of the connecting rope extends to the outside of the support tube and is fixedly connected to an elastic wristband. One end of the elastic wristband is fixedly connected to a shell. A metal sheet is fixedly connected to the inner bottom wall. Several limiting holes are equidistantly opened on the inner wall of the support tube relative to the position of the limiting block, and one end of each of the two limiting blocks extends through into the corresponding limiting hole.

[0007] Preferably, a first spring is fixedly connected to the outer wall of one end of each of the two limiting blocks located in the cavity, and the other end of each of the two first springs is fixedly connected to the slider.

[0008] Preferably, a second spring is fixedly connected to the upper surface of the slider, and the other end of the second spring is fixedly connected to the support tube.

[0009] Preferably, the inner bottom wall of the base is provided with a groove and a grounding wire is fixedly connected thereto, and one end of the grounding wire extends through into the connecting rope and is fixedly connected to the metal sheet.

[0010] Preferably, both limiting blocks are arranged in a triangular shape.

[0011] The beneficial effects of this utility model are as follows: the elastic wristband is fixed to the wrist, the metal plate abuts against the wrist, and the grounding wire provides anti-static protection for the user. Pulling the connecting rope upwards moves the slider to the desired position, adjusting the wristband length. When not in use, pulling the connecting rope upwards moves the limiting block out of the limiting hole, and the second spring pushes the slider to the bottom of the support tube to store the connecting rope, reducing the wristband length. The wristband length can be adjusted, increasing the flexibility of the equipment and preventing the wristband from being too short and affecting its use. At the same time, storing the wristband prevents it from being discarded at will when not in use. Attached Figure Description

[0018] Reference Figure 1-5 The safety production anti-static device includes a base 1, a support tube 2 fixedly connected to the upper surface of the base 1, a slider 3 slidably connected to the inner wall of the support tube 2, a cavity symmetrically opened inside the slider 3, a limit block 4 slidably connected to the inner wall of each of the two cavities, a pull rope 5 fixedly connected to one side of the outer wall of each of the two limit blocks 4, and one end of each pull rope 5 extending through a hole to the outside of the slider 3 and fixedly connected to a connecting rope 6.

[0019] One end of the connecting rope 6 extends to the outside of the support tube 2 and is fixedly connected to an elastic wristband 7. One end of the elastic wristband 7 is fixedly connected to the outer shell 8, and a metal sheet 9 is fixedly connected to the inner bottom wall of the outer shell 8. Several limiting holes 10 are equidistantly opened on the inner wall of the support tube 2 relative to the position of the limiting block 4, and one end of each of the two limiting blocks 4 extends through into the corresponding limiting hole 10. The outer shell 8 is made of PU material.

[0020] Among them, the two limiting blocks 4 are fixedly connected to the outer wall of one end of the cavity with a first spring 11, and the other end of the two first springs 11 are fixedly connected to the slider 3, so as to facilitate the use of the first springs 11 to push the limiting blocks 4 to move.

[0021] The upper surface of the slider 3 is fixedly connected to a second spring 12, and the other end of the second spring 12 is fixedly connected to the support tube 2, so that the slider 3 can be moved by using the second spring 12.

[0022] The base 1 has a groove on its inner bottom wall and a grounding wire 13 is fixedly connected thereto. One end of the grounding wire 13 extends through the connecting rope 6 and is fixedly connected to the metal plate 9. The end of the grounding wire 13 located inside the base 1 is threaded. The grounding wire 13 is made of metal and is wire-shaped, which makes it easy to discharge static electricity using the grounding wire 13.

[0023] Both limit blocks 4 are arranged in a triangular shape.

[0024] When using this device, place the base 1 on the ground, with the grounding wire 13 abutting against the ground. The user pulls the connecting rope 6 outward, and the connecting rope 6 moves outward through the pull rope 5. The pull rope 5 pulls the limiting block 4 out of the limiting hole 10. At the same time, the connecting rope 6 pulls the slider 3 upward and compresses the second spring 12. Adjust the height of the elastic wristband 7 and put it on the user's wrist. The metal piece 9 abuts against the user's wrist. The grounding wire 13 conducts static electricity from the user's body surface through the ground. After moving the slider 3 to the desired position, the first spring 11 pushes the limiting block 4 into the limiting hole 10 to limit and fix the slider 3. When not in use, remove the elastic wristband 7 from the wrist and pull the connecting rope 6 upward. The connecting rope 6 pulls the limiting block 4 out of the limiting hole 10. The second spring 12 pushes the slider 3 into the bottom of the support tube 2 to store the connecting rope 6.
