Technical Field
[0001] This utility model relates to the field of human body static electricity release technology, and in particular to a static-conducting metal chain curtain for an explosion-proof vestibule. Background Technology
[0002] Explosion-proof vestibules are mostly safety protection structures for explosion-proof workshops, which are special workplaces primarily used for the production and processing of explosive and flammable materials. These workshops employ various technologies and safety equipment to control and limit factors that could lead to fires and explosions, thereby ensuring the safety of production operations. Explosion-proof vestibules are mainly used to reduce the impact range of blast shock waves and limit the diffusion of hazardous gases. Through a multi-layered, staggered door design, they reduce the direct damage of blast shock waves to adjacent areas, preventing airflow from breaking through one door and directly entering other areas. The conductive metal chain door curtain is usually made of stainless steel or conductive alloy, forming a hanging chain structure through spiral weaving, combining flexibility and conductivity. The top beam of the curtain is connected to a grounding wire, which is connected to the building's grounding system through a conductor, reducing static electricity carried by people and objects and preventing explosions.
[0003] A search of the Chinese patent "An Antistatic Door Curtain" with publication number "CN214708134U" revealed that the curtain rope made of carbon fiber and metal wire has a gentle discharge effect. However, because the exposed metal ground wire is in the same space as chemical products for a long time, the connection between the ground wire and the beam is easily corroded, which affects the outward conduction of static electricity.
[0004] Therefore, a static-dissipating metal chain curtain for explosion-proof vestibules is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a static-dissipating metal chain door curtain for explosion-proof vestibules in order to solve the above-mentioned problems. This improves the problem that the exposed ground wire metal is in the same space with chemical products for a long time, and the connection between the ground wire and the crossbeam is easily corroded, which affects the outward conduction of static electricity.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a static-dissipating metal chain door curtain for an explosion-proof vestibule, comprising: a crossbeam, one side of which is fixedly connected to a ground wire; a conductive mechanism, which is sleeved on the surface of the ground wire and installed on one side of the crossbeam; wherein, the conductive mechanism includes a protective component installed on one side of the crossbeam, the protective component being sleeved on the surface of the ground wire, and a plurality of conductive components connected to the lower end of the protective component, the conductive components being evenly distributed in a straight line along the lower end of the protective component.
[0007] Preferably, the protective component includes two guide rails fixedly connected to one side of the crossbeam. A rubber block is fixedly connected to one end of the guide rail near the ground wire. A rubber sleeve is embedded in the inner wall of the rubber block and is fitted onto the surface of the ground wire. A cover plate is slidably connected to the surface of the guide rail. A connecting block is fixedly connected to one end of the cover plate away from the rubber block. Two guide strips are fixedly connected to the side of the cover plate near the crossbeam. The guide strips are slidably connected to the surfaces of adjacent guide rails.
[0008] Preferably, the conductive component includes a connecting round block fixedly connected to the lower end of the cover plate, a threaded tube fixedly connected to the lower end of the connecting round block, a threaded cylinder threadedly connected to the inner wall of the threaded tube, and a metal braided tube fixedly connected to the surface of the threaded tube, the metal braided tube being located below the threaded tube.
[0009] Preferably, a fixing block is fixedly connected between the two guide slides, and a connecting film is fixedly connected to the side of the fixing block near the rubber block, and the connecting film is in contact with the surface of the cover plate.
[0010] Preferably, a connecting hole is provided on one side of the connecting block, the connecting hole extends into the interior of the fixing block, and a connecting bolt is threaded onto the inner wall of the connecting hole.
[0011] Preferably, a flexible rope is fixedly connected to the inner wall of the threaded cylinder, and the flexible rope is located inside the metal braided tube.
[0012] Preferably, the metal braided tube is fitted with a plurality of silver-plated metal balls on its outer surface, and the inner wall of the lower silver-plated metal ball is fixedly connected to the surface of the metal braided tube.
[0013] The beneficial effects of this utility model are: The aforementioned anti-static metal chain door curtain for the explosion-proof vestibule, through its protective components, provides protection at the connection between the ground wire and the crossbeam. The crossbeam and cover plate combine to form a protective cavity, preventing the exposed ground wire from being exposed to chemicals in the same space for extended periods. This reduces the corrosion of the ground wire connection by external chemicals. The tight fit between the connecting bolts and fixing blocks ensures a stable connection between the ground wire and the crossbeam inside the cavity, maintaining good conductivity and minimizing the impact on the outward conduction of static electricity.
[0014] The conductive components are modularly designed, allowing for quick separation from the threaded tube by rotating the threaded cylinder. This modular assembly facilitates the removal of the silver-plated metal balls for oxide layer cleaning, improving the ease of cleaning the metal ball surface and ensuring good conductivity on the silver-plated metal ball surface.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] In practical implementation: such as Figure 1-4 As shown, an anti-static metal chain door curtain for an explosion-proof vestibule includes: a crossbeam 1, with a ground wire 2 fixedly connected to one side of the crossbeam 1; a conductive mechanism 3, which is sleeved on the surface of the ground wire 2 and installed on one side of the crossbeam 1; wherein, the conductive mechanism 3 includes a protective component 31 installed on one side of the crossbeam 1, the protective component 31 being sleeved on the surface of the ground wire 2, and a plurality of conductive components 32 connected to the lower end of the protective component 31, the conductive components 32 being evenly distributed in a straight line along the lower end of the protective component 31; It should be noted that when a person comes into contact with the door curtain, the static charge they carry is released through the conductive chain and grounding system to prevent electrostatic sparks from igniting explosive gases. There is a grounding wire 2 on the conductive metal chain door curtain beam 1, which is connected to the ground. This ensures that the static electricity is very small before the person enters the electrostatic sensitive area, thus playing a protective role and ensuring that the static charge is effectively transferred when the person or equipment comes into contact with it. like Figure 1 , Figure 2 , Figure 3As shown, the protective component 31 includes two guide slides 311 fixedly connected to one side of the crossbeam 1. A rubber block 312 is fixedly connected to one end of the guide slide 311 near the ground wire 2. A rubber sleeve 3121 is embedded in the inner wall of the rubber block 312 and is fitted onto the surface of the ground wire 2. A cover plate 313 is slidably connected to the surface of the guide slide 311. A connecting block 315 is fixedly connected to one end of the cover plate 313 away from the rubber block 312. Two guide strips 3131 are fixedly connected to one side of the cover plate 313 near the crossbeam 1. The guide strips 3131 are slidably connected to the surface of the adjacent guide slide 311. A fixing block 314 is fixedly connected between two guide slides 311. A connecting piece 3141 is fixedly connected to the side of the fixing block 314 near the rubber block 312. The connecting piece 3141 is in contact with the surface of the cover plate 313. A connecting hole 3151 is opened on one side of the connecting block 315. The connecting hole 3151 extends into the interior of the fixing block 314. A connecting bolt 3152 is threaded onto the inner wall of the connecting hole 3151. When the device is in use, the combination of the crossbeam 1 and the cover plate 313 forms a protective cavity, which protects the connection between the ground wire 2 and the crossbeam 1, reducing the corrosion of the metal connection of the ground wire 2 by external chemical materials. The rubber block 312 and the connecting film 3141 can help to form a relatively good sealing effect inside the cavity, reducing the corrosion of the metal connection of the ground wire 2 by external moisture. Furthermore, the cooperation between the connecting bolt 3152 and the fixing block 314 ensures that the connecting block 315 fits tightly against the surface of the fixing block 314, ensuring a stable connection between the ground wire 2 and the crossbeam 1 inside the cavity and maintaining good conductivity. like Figure 1 , Figure 2 , Figure 4 As shown, the conductive component 32 includes a connecting round block 321 fixedly connected to the lower end of the cover plate 313. A threaded tube 323 is fixedly connected to the lower end of the connecting round block 321. A threaded cylinder 322 is threadedly connected to the inner wall of the threaded tube 323. A metal braided tube 324 is fixedly connected to the surface of the threaded tube 323. The metal braided tube 324 is located below the threaded tube 323. A flexible rope 325 is fixedly connected to the inner wall of the threaded cylinder 322. The flexible rope 325 is located inside the metal braided tube 324. A plurality of silver-plated metal balls 326 are sleeved on the outside of the metal braided tube 324. The inner wall of the lower silver-plated metal ball 326 is fixedly connected to the surface of the metal braided tube 324. The device forms a relatively tight connection by inserting the threaded cylinder 322 into the threaded tube 323 through the knob. When a thick oxide layer is formed on the surface of the silver-plated metal ball 326, the threaded cylinder 322 can be quickly separated from the threaded tube 323 by turning the knob, forming a modular assembly effect. This makes it easy to remove the silver-plated metal ball 326 for oxide layer cleaning, ensuring that the surface of the silver-plated metal ball 326 can form good conductivity.
[0019] In use, the crossbeam 1 and the cover plate 313 combine to form a protective cavity, protecting the connection between the ground wire 2 and the crossbeam 1. The rubber block 312 and the connecting film 3141 assist in forming a relatively good sealing effect inside the cavity, reducing the corrosion of the metal connection of the ground wire 2 by external moisture. The connecting bolt 3152 cooperates with the fixing block 314, and the connecting block 315 will fit tightly against the surface of the fixing block 314. When a thick oxide layer is formed on the surface of the silver-plated metal ball 326, the threaded cylinder 322 can be quickly separated from the threaded tube 323 by turning the knob threaded cylinder 322, forming a modular assembly effect. This makes it easy to remove the oxide layer from the silver-plated metal ball 326 for cleaning, ensuring good conductivity on the surface of the silver-plated metal ball 326.
[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
