Description

Technical Field

[0001] This utility model belongs to the field of antistatic equipment technology, specifically relating to a track-type antistatic wrist strap. Background Technology

[0002] Static electricity is the accumulation of stationary electric charge on the surface of an object. It is commonly seen in everyday life scenarios such as the blue light emitted when taking off clothing in dry winter conditions or hair flying when combing. It is formed by the transfer of electrons due to the contact and separation of different objects. Essentially, it is the charge imbalance caused by electrons in atoms being forced out of their orbits by external forces. Triboelectric charging is a process of electron transfer through contact separation. Discharge occurs when a charged body comes into contact with a grounded object. Its applications include electrostatic dust removal, electrostatic spraying, electrostatic flocking, electrostatic copying, and air purification. In the field of architecture, the hazards of static electricity mainly manifest as high-voltage discharge caused by charge accumulation, which may interfere with equipment operation or cause safety accidents. Its main hazards include fire or explosion, electric shock to humans, and industrial damage, especially in flammable and explosive environments (such as gas stations and coal mines).

[0003] Especially in equipment involving electronic components, accumulated static electricity can break down circuits and damage components, causing irreversible damage. Therefore, DC equipment or precision equipment is usually equipped with wearable electrostatic wrist straps. These straps conduct electricity through the human body, allowing static electricity to be discharged via the strap to the equipment's grounding point, thus preventing damage to components or equipment. However, these electrostatic wrist straps require a high level of grounding. Only with proper grounding can electrostatic damage be avoided. If the grounding is interrupted, static electricity from the human body will directly conduct to the equipment's casing and cannot be discharged, thus increasing the risk of electrostatic damage and creating safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the background technology mentioned above, and to provide a track-type anti-static wristband that conducts the static electricity carried by the human body to the grounding device through the wristband, without directly conducting with the equipment, thereby avoiding static damage caused by poor grounding of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a track-type antistatic wristband, comprising a wristband body, an elastic conductive rope, a connecting device, and a grounding body. The wristband body is composed of a braided wrist buckle and a metal block. The metal block is sewn and fixed to the inner surface of the middle part of the braided wrist buckle. One end of the elastic conductive rope is rotatably connected to the metal block, and the other end is inserted into the connecting device to connect the connecting device to the metal block. The grounding body is made of a square steel pipe. A horizontal groove is opened in the middle of the front of the steel pipe, and a placement groove is opened at both ends of the groove. The connecting device includes a limiting plate, a spring, and a connecting ring. The limiting plate is set in the inner cavity of the steel pipe. A set of springs is set on the back of the limiting plate so that the front of the limiting plate fits against the inner wall of the steel pipe. A connecting ring is set at the center of the front of the limiting plate so that the upper and lower limits of the connecting ring are in the groove and can move freely along the direction of the groove.

[0006] Furthermore, the front of the limiting plate is also provided with a set of vertical slots, which are located at the upper and lower ends of the limiting plate, and the length of the slots is not less than the obstruction length between the limiting plate and the steel pipe.

[0007] Furthermore, the connecting ring is made of conductive material, and a tapered insertion hole is opened in the middle of the connecting ring. A fastening nut is connected to the tapered insertion hole, and an elastic conductive rope is connected to the insertion hole for conduction.

[0008] Furthermore, a spiral thread is provided in the center of the front of the limiting plate, and a connecting thread is provided on the outer contour of the corresponding connecting ring, and the connecting ring is threadedly connected to the limiting plate.

[0009] Furthermore, the spring is a conical compression spring, with a limit post in the middle of the spring, and the limit post is fixedly connected to the limit plate.

[0010] The beneficial effects of this utility model are: 1) This utility model is equipped with a connecting device, which is slidably connected to the grounding body through the limiting plate, so that the static electricity carried by the human body can be conducted to the grounding body through the wristband and elastic conductive rope. When in use, the static electricity can be discharged without passing through the equipment, reducing the risk of equipment damage. At the same time, the grounding body is installed separately on the four sides of the wall and connected to the ground. When in use, the position of the connecting device on the grounding body can be moved to achieve all-round static electricity discharge without dead angles. No matter where the equipment is laid out, it can protect the safety of the equipment and has a simple structure and is easy to use. Attached Figure Description

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0018] Example: Figure 1-5 As shown, the present invention discloses a track-type antistatic wristband, comprising a wristband body 1, an elastic conductive rope 2, a connecting device 3, and a grounding body 4. The wristband body 1 consists of a braided wrist buckle and a metal block. The metal block is sewn and fixed to the inner surface of the middle part of the braided wrist buckle. One end of the elastic conductive rope 2 is rotatably connected to the metal block, and the other end is inserted into the connecting device 3 to connect the connecting device 3 to the metal block. The grounding body 4 is made of a square steel pipe 5. A horizontal groove 6 is opened in the middle of the front of the steel pipe 5, and a placement groove 7 is opened at both ends of the groove 6. The connecting device 3 includes a limiting plate 8, a spring 9, and a connecting ring 10. The limiting plate 8 is set in the inner cavity of the steel pipe 5. A set of springs 9 is set on the back of the limiting plate 8 so that the front of the limiting plate 8 is attached to the inner wall of the steel pipe 5. A connecting ring 10 is set at the center of the front of the limiting plate 8 so that the upper and lower limits of the connecting ring 10 are in the groove 6 and can move freely along the direction of the groove 6. The placement slot 7 is used to accommodate the entry and exit of the limiting plate 8. When in use, the limiting plate 8 is installed in the placement slot 7 at the corresponding position according to the position of the operating equipment, so that the connecting device 3 and the grounding body 4 can be detachably connected and are easy to carry and move. When in use, the grounding body 4 is embedded in the four walls of the room, and a placement slot 7 is opened on each side of the grounding body 4 to facilitate the quick installation and use of the connecting device 3.

[0019] The front of the limiting plate 8 is also provided with a set of vertical slots 11, which are located at the upper and lower ends of the limiting plate 8. The length of the slots is not less than the blocking length between the limiting plate 8 and the steel pipe 5. The spaced slots 11 can increase the friction force when the limiting plate 8 is connected to the inner wall of the steel pipe 5, and prevent poor contact of the limiting plate 8 due to unevenness of the inner wall of the steel pipe 5, which would affect the electrostatic conduction effect.

[0020] The connecting ring 10 is made of conductive material. A tapered insertion hole 12 is opened in the middle of the connecting ring 10, and a fastening nut 13 is connected to the tapered insertion hole 12. The elastic conductive rope 2 is connected to the insertion hole for conduction. The opening size of the tapered insertion hole can be adjusted by tightening or loosening the fastening nut 13, that is, the internal clamping space can be adjusted and changed to accommodate different sizes and models of elastic conductive ropes 2, thereby improving the practicality of the device. At the same time, the elastic conductive rope 2 can be detachably connected to the connecting ring 10. The split structure can save resources and avoid waste.

[0021] The limiting plate 8 also has a spiral thread 14 in the center of its front side, and a connecting thread 15 is provided on the outer contour of the corresponding connecting ring 10. The connecting ring 10 is threadedly connected to the limiting plate 8. The threaded connection facilitates quick disassembly of the connecting device 3, allowing the wristband and elastic conductive rope 2 to be separated from the connecting device 3. This makes it easy to replace and repair the wristband. Even if the device is damaged, it does not need to be completely discarded. The parts can be replaced through the detachable parts, which can save materials and reduce waste.

[0022] Spring 9 is a conical compression spring 9, with a limiting post 16 in the middle of spring 9, which is fixedly connected to limiting plate 8. In use, three springs 9 (upper, middle, and lower) and limiting posts 16 are used. The limiting posts 16 are fixedly connected to the back of limiting plate 8. The small end of spring 9 is fixed to limiting plate 8, and its long end extends outward to contact the inner wall of steel pipe 5. The conical compression spring 9 supports limiting plate 8 in its normal state, pressing it tightly against the inner wall of steel pipe 5. Spring 9 can be compressed, which facilitates squeezing limiting plate 8 into steel pipe 5 to separate it from the inner wall, thus allowing it to move left and right. After releasing, spring 9 returns to its original position, pressing limiting plate 8 tightly against the inner wall of steel pipe 5. At this time, limiting plate 8 and steel pipe 5 are connected, allowing for static discharge. The structure is simple and the operation is convenient.

[0023] This utility model is equipped with a connecting device that slides between a limiting plate and the grounding body. This allows static electricity carried by the human body to be conducted to the grounding body through a wristband or elastic conductive rope. During use, static electricity can be discharged without passing through the equipment, reducing the risk of equipment damage. At the same time, the grounding body is installed separately on the four sides of the wall and connected to the ground. During use, the position of the connecting device on the grounding body can be moved to achieve all-round static electricity discharge without dead angles. It can protect the equipment safety regardless of where the equipment is located, and the structure is simple and easy to use.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
