Description

Technical Field

[0001] This utility model relates to the field of antistatic technology, specifically to an antistatic device worn by personnel. Background Technology

[0002] In chemical production environments such as compound product tank areas, the generation and accumulation of static electricity is a common problem. Static electricity is usually generated by processes such as friction, contact, and separation between objects. For example, during operations such as liquid transportation, stirring, and filling, the interaction between the liquid and equipment such as pipes and containers generates static electricity. In addition, workers' walking and operating activities in the tank area can also generate static electricity on their bodies. If this static electricity is not controlled and eliminated, it may cause serious safety accidents. For example, sparks generated by electrostatic discharge may ignite flammable and explosive gases or liquids, leading to fires or explosions, causing huge losses to personnel and company property. Therefore, how to effectively prevent the accumulation and hazards of static electricity is an urgent problem to be solved in the safety management of compound product tank areas.

[0003] Currently, the common anti-static measures in the chemical production field mainly include the following two types, but both have limitations; 1. Anti-static flooring Antistatic flooring or tiles can be used to reduce the generation and accumulation of static electricity. However, antistatic flooring has some limitations in practical use. First, the installation cost is relatively high, which can be a significant financial burden for small businesses or localized renovations. Second, the antistatic effect of antistatic flooring is affected by factors such as environmental humidity; its antistatic performance may decrease in dry environments. Furthermore, damage or wear to the flooring can also affect its antistatic effectiveness.

[0004] 2. Grounding devices connect equipment or pipes to the ground, allowing static electricity to be released promptly. While grounding is an effective anti-static measure, in practice, its installation and maintenance require professional technicians, resulting in high installation costs. Furthermore, the grounding resistance needs regular testing and maintenance to ensure its effectiveness. Additionally, grounding devices primarily target equipment or pipes, offering limited effectiveness in eliminating static electricity from the human body. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and proposes an anti-static device for personnel to wear.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: An antistatic device for personal wear includes a rubber band strap for fixing to the human body. A contact metal piece is fixedly provided on the inner side of the rubber band strap that contacts the human body. The lower end of the contact metal piece is connected to a grounding mechanism via a wire. The grounding mechanism includes a grounding metal piece, a U-shaped clamp, and a hollow adjusting plate. The U-shaped clamp has its opening facing downward and is used to clamp onto the side of the person's shoe. The hollow adjusting plate slides in conjunction with the U-shaped clamp. The bottom of the hollow adjusting plate is connected to the grounding metal piece. A height adjustment mechanism is provided between the hollow adjusting plate and the U-shaped clamp to adjust the height of the hollow adjusting plate and the grounding metal piece.

[0007] Furthermore, the hollow regulating plate is a hollow rectangular frame structure, and the inner wall of the hollow regulating plate is fitted with the outer wall of the U-shaped clamp.

[0008] Furthermore, the height adjustment mechanism includes a limiting toothed plate and an internal threaded block; the internal threaded block has a U-shaped structure, with both ends of the internal threaded block fixed to the outside of the U-shaped clamping plate, and the limiting toothed plate is slidably connected inside the internal threaded block; the outer wall of the hollow adjustment plate is provided with several limiting tooth grooves from top to bottom; the limiting toothed plate is engaged with the limiting tooth grooves.

[0009] Furthermore, a through groove is formed between the inner side of the internal thread block and the outer wall of the U-shaped clamp; the limiting tooth plate is slidably disposed inside the through groove.

[0010] Furthermore, the inner diameter of the hollow structure of the hollow adjusting plate is adapted to the thickness of the internal thread block, so that the hollow adjusting plate is fitted on the outside of the internal thread block; the two ends of the limiting tooth plate located outside the through groove mesh with the limiting tooth groove.

[0011] Furthermore, the side of the internal threaded block away from the hollow adjustment plate is threaded with a bolt, which is threadedly connected to the limiting tooth plate.

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0023] See Figures 1 to 4This embodiment proposes an anti-static device for personnel, including a rubber band strap 1 and a grounding mechanism 6. One end of the rubber band strap 1 is fixedly provided with a Velcro 2, and the other end is fixedly provided with a Velcro 3. A contact metal piece 4 is fixedly provided on the inner side of the rubber band strap 1. The lower end of the contact metal piece 4 is connected to the grounding mechanism 6 through a wire 5. When workers walk or perform related operations in the compound finished product tank area, static electricity will inevitably be generated between the human body and objects such as the ground and equipment. This static electricity will be conducted through the legs of the human body to the contact metal piece 4 on the inner side of the rubber band strap 1. As the starting point of static electricity conduction, the good conductivity of the contact metal piece 4 can ensure that the static electricity is smoothly transferred from the human body to the contact metal piece 4.

[0024] The elastic band strap 1 has a Velcro 2 and a Velcro 3 fixed at one end. The Velcro 2 and the Velcro 3 can be used to firmly bind the elastic band strap 1 to the worker's calf. This bonding method is not only simple and quick to operate, but also can be flexibly adjusted according to the different calf sizes of different workers to ensure that the elastic band strap 1 fits tightly to the leg, so that the contact metal plate 4 can maintain good contact with the human body, thereby ensuring that static electricity can be efficiently conducted from the human body to the contact metal plate 4.

[0025] Static electricity is conducted from the contact metal plate 4 to the wire 5 and transmitted along the path of the wire 5. The wire 5 serves as the key channel for static electricity transmission, ensuring that static electricity can be transmitted quickly and stably from the contact metal plate 4 to the grounding mechanism 6, avoiding leakage or accumulation of static electricity during transmission, and ensuring that static electricity can be smoothly guided to the grounding mechanism 6.

[0026] As an example of this utility model, the grounding mechanism 6 includes a grounding metal sheet 7, a U-shaped clamp 8, anti-slip teeth 9, and a hollow adjustment plate 16. The U-shaped clamp 8, with its opening facing downwards, is used to clamp onto the side of the worker's shoe, thereby securing the entire grounding mechanism 6. The inner side of the U-shaped clamp 8 is short and thin, and can be fitted with a soft material layer to enhance comfort for the worker's feet. Alternatively, work shoes with a dedicated clamping layer can be used, allowing the U-shaped clamp 8 to be directly clamped onto the outside of the shoe, avoiding any impact on the worker's walking. To improve the anti-slip effect after clamping, anti-slip teeth 9 are fixedly provided on the inner side of the U-shaped clamp 8. When the U-shaped clamp 8 is clamped onto the side of the shoe, the anti-slip teeth 9 can tightly adhere to the surface of the shoe side, increasing friction and preventing the U-shaped clamp 8 from sliding on the side of the shoe, thus ensuring stable contact between the grounding metal plate 7 and the ground.

[0027] The hollow regulating plate 16 is a hollow rectangular frame structure. The inner wall of the hollow regulating plate 16 is fitted to the outer wall of the U-shaped clamp 8. A height adjustment mechanism is provided between the hollow regulating plate 16 and the U-shaped clamp 8 to adjust their relative position. A grounding metal plate 7 is connected to the bottom of the hollow regulating plate 16. The hollow regulating plate 16 is in a vertical position, while the grounding metal plate 7 is in a horizontal position. Static electricity is conducted to the grounding metal plate 7 through the wire 5. The grounding metal plate 7 serves as the terminal for static electricity discharge, and its contact with the ground provides a stable discharge path for the static electricity.

[0028] Because the height of the staff's shoes varies, a height adjustment mechanism is set up to adjust the position of the hollow adjustment plate 16 in order to accommodate different shoe heights, thereby adjusting the height of the grounding metal piece 7.

[0029] The height adjustment mechanism includes a limiting toothed plate 10, a limiting toothed groove 11, a through groove 12, a knob 13, a bolt 14, and an internal threaded block 15. The internal threaded block 15 has a U-shaped structure, and both ends of the internal threaded block 15 are fixed to the outside of the U-shaped clamping plate 8, so that the inner side of the internal threaded block 15 and the outer wall of the U-shaped clamping plate 8 form a through groove 12. A hollow adjusting plate 16 is slidably provided on the outside of the internal threaded block 15: that is, the inner diameter of the hollow structure of the hollow adjusting plate 16 is adapted to the thickness of the internal threaded block 15, so that the hollow adjusting plate 16 can be fitted on the outside of the internal threaded block 15. Several limiting toothed grooves 11 are provided on the outer wall of the hollow adjusting plate 16 from top to bottom. The limiting toothed plate 10 is slidably provided inside the through groove 12, and the limiting toothed plate 10 is engaged with the limiting toothed groove 11. A bolt 14 is threadedly connected to the side of the internal threaded block 15 away from the hollow adjustment plate 16. One end of the bolt 14 is located outside the internal threaded block 15 and is fixedly equipped with a knob 13. The other end of the bolt 14 is threadedly connected to the limiting tooth plate 10. By rotating the knob 13, the bolt 14 is driven to rotate inside the internal threaded block 15. Since the bolt 14 is threadedly connected to the limiting tooth plate 10, the rotation of the bolt 14 will push the limiting tooth plate 10 to slide left and right in the through groove 12. When it is necessary to adjust the height of the hollow adjustment plate 16, the bolt 14 is unscrewed to disengage the limiting tooth plate 10 from the limiting tooth groove 11. At this time, the height of the hollow adjustment plate 16 can be adjusted. After adjustment, the bolt 14 is tightened again to make the limiting tooth plate 10 tightly engage with the limiting tooth groove 11, thereby fixing and limiting the hollow adjustment plate 16. The movement of the hollow adjustment plate 16 will change the position of the grounding metal piece 7, thereby adapting to different shoe heights.

[0030] The teeth of the limiting tooth groove 11 are right-angled, which can ensure the stability of the limiting tooth plate 10 when it is engaged, prevent the hollow adjusting plate 16 from shaking or shifting during movement, and further ensure the stability and reliability of the grounding metal piece 7 in contact with the ground.

[0031] In this embodiment, the wire 5 is connected to the internal thread block 15. The internal thread block 15 and the hollow adjustment plate 16 are made of conductive materials. Static electricity is transferred to the grounded metal plate 7 through the wire 5, the internal thread block 15, and the hollow adjustment plate 16.

[0032] The working principle of an anti-static device worn by personnel is as follows: When in use, when staff walk or perform related operations in the compound finished product tank area, static electricity will inevitably be generated between the human body and objects such as the ground and equipment. This static electricity will be conducted through the legs of the human body to the contact metal plate 4 on the inside of the rubber band strap 1. As the starting point of static electricity conduction, the good conductivity of the contact metal plate 4 can ensure that the static electricity is smoothly transferred from the human body to the contact metal plate 4.

[0033] One end of the elastic band strap 1 is fixed with a Velcro 2, and the other end is fixed with a Velcro 3. Through the adhesion of the Velcro 2 and the Velcro 3, the elastic band strap 1 can be firmly tied to the worker's calf. This adhesion method is not only simple and quick to operate, but also can be flexibly adjusted according to the different calf thicknesses of different workers to ensure that the elastic band strap 1 fits tightly to the leg, so that the contact metal plate 4 can maintain good contact with the human body, thereby ensuring that static electricity can be efficiently conducted from the human body to the contact metal plate 4.

[0034] Static electricity is conducted from the contact metal plate 4 to the conductor 5 and then propagates along the path of the conductor 5. After being transmitted to the grounding mechanism 6, the static electricity finally reaches the grounding metal plate 7. As the terminal for static electricity release, the grounding metal plate 7 provides a stable release path for the static electricity through its contact with the ground. Under the clamping action of the U-shaped clamp 8, the grounding metal plate 7 can firmly contact the side of the shoe, and then safely conduct the static electricity to the ground through the contact between the sole of the shoe and the ground, thus achieving effective release of static electricity.

[0035] Rotating knob 13 causes bolt 14 to rotate inside threaded block 15. Since bolt 14 is rotatably connected to limiting tooth plate 10, the rotation of bolt 14 pushes limiting tooth plate 10 to slide in through groove 12. When the height of hollow adjusting plate 16 needs to be adjusted, unscrew bolt 14 to disengage limiting tooth plate 10 from limiting tooth groove 11. At this time, the height of hollow adjusting plate 16 can be adjusted. After adjustment, tighten bolt 14 to make limiting tooth plate 10 and limiting tooth groove 11 tightly engaged, thus fixing and limiting hollow adjusting plate 16. The movement of hollow adjusting plate 16 will change the position of grounding metal piece 7, thereby adapting to different shoe heights.

[0036] The anti-slip teeth 9 on the inner side of the U-shaped clamp 8 play an important role in preventing slippage during the operation of the device. When the U-shaped clamp 8 is clamped on the side of the shoe, the anti-slip teeth 9 can fit tightly with the surface of the side of the shoe, increasing the friction and preventing the U-shaped clamp 8 from sliding on the side of the shoe, thereby ensuring stable contact between the grounding metal piece 7 and the ground. The right-angle structure of the limiting tooth groove 11 can ensure the stability of the limiting tooth plate 10 when it is engaged, preventing the hollow adjusting plate 16 from shaking or shifting during movement, further ensuring the stability and reliability of the contact between the grounding metal piece 7 and the ground.

[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
