Description

Technical Field

[0001] The utility model relates to the technical field of anti-static detection devices, in particular to an anti-static grounding device for safe production of fireworks. Background Art

[0002] During the production, handling, loading and unloading of fireworks and firecrackers, drugs or operators may generate accumulation of static electricity. When the accumulated charge triggers static discharge, the energy of the generated electric spark is greater than the minimum ignition energy of the fireworks or black powder, which will cause them to burn and explode. Therefore, an anti-static grounding device must be installed in the fireworks and firecracker processing and production workplace. It prevents the generation of static electricity and limits the static electricity that has been generated so that it does not reach a dangerous level. Secondly, the generated charge is leaked or conducted away as quickly as possible, thereby eliminating a large amount of charge accumulation. When a person enters the anti-static area, he directly touches the static electricity elimination ball, and the current is directly conducted into the ground through the static electricity metal wire.

[0003] At present, during the use of anti-static grounding devices for safe production of fireworks, the hands of relevant personnel may be contaminated with dust during the handling and loading and unloading process. After long-term use, dust is easily adhered to the surface of the static elimination ball, which affects the static elimination effect. Based on this, we propose an improved anti-static grounding device for safe production of fireworks. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, an anti-static grounding device for safe production of fireworks includes a base 1, a static elimination ball 2, a support plate 4 and a connecting plate 10, both sides of the upper end surface of the support plate 4 are fixedly connected with side plates 5, the static elimination ball 2 is rotatably connected between the two side plates 5 through a rotating shaft, a cleaning plate 14 is arranged on the outer wall of the lower end of the static elimination ball 2, a sponge brush 15 is fixedly arranged on the upper end of the cleaning plate 14, a sleeve rod 13 is fixedly connected to the lower end surface of the cleaning plate 14, a cylindrical groove is provided in the sleeve rod 13, a static conductive spring 16 is fixedly connected in the cylindrical groove, a static conductive block 17 is fixedly connected to the upper end of the static conductive spring 16, the upper end of the static conductive block 17 penetrates the sponge brush 15 and is slidably pressed on the surface of the static elimination ball 2.

[0022] In this embodiment, sliders 8 are slidably provided in the two side panels 5, a connecting plate 10 is fixedly connected between the two sliders 8, a mounting cap 11 is fixedly connected to the lower end of the connecting plate 10, a mounting hole 12 is opened in the middle of the connecting plate 10 and the mounting cap 11, a sleeve rod 13 is movably sleeved in the mounting hole 12, and the cleaning plate 14 and the sponge brush 15 can be conveniently disassembled for cleaning by movably sleeved in the mounting hole 12 by the sleeve rod 13.

[0023] In this embodiment, a slide groove 6 is provided on the opposite side of the two side panels 5, and a slide rod 7 is fixedly connected between the upper and lower inner walls of the two slide grooves 6. Two sliders 8 are respectively slidably sleeved on the outer walls of the two slide rods 7. Support springs 9 are fixedly connected between the lower ends of the two sliders 8 and the inner walls of the slide grooves 6. The two support springs 9 are respectively movably sleeved on the outer ends of the two slide rods 7. The support springs 9 can be compressed when the sleeve rod 13 is conveniently disassembled, thereby facilitating the downward pressing of the connecting plate 10.

[0024] In this embodiment, a static conductive metal wire 18 is fixedly connected to the lower end of the mounting cap 11, and a vertical pole 3 is fixedly connected between the base 1 and the support plate 4. The lower end of the static conductive metal wire 18 passes through the vertical pole 3 and the base 1 in sequence, and static electricity is conducted into the ground through the static conductive metal wire 18.

[0025] In this embodiment, the connecting plate 10, the mounting cap 11 and the sleeve rod 13 are all made of copper metal, and the support plate 4 and the two side plates 5 are all made of hard plastic, which reduces the weight of the upper end of the device and improves the stability of the device.

[0027] It should be noted that the utility model is an anti-static grounding device for safe production of fireworks. When in use, since the static elimination ball 2 is rotatably connected to the side plate 5, it will inevitably rotate when a person touches it. When the static elimination ball 2 rotates, the sponge brush 15 arranged at its lower end can be used to clean it, so there is no need to additionally remove dust from the static elimination ball 2, which is convenient and saves trouble. At the same time, due to the elastic force of the static conductive spring 16, the static conductive block 17 can be driven to penetrate the middle of the sponge brush 15 and be pressed on the surface of the static elimination ball 2, so that static electricity can be discharged to avoid affecting the static elimination function of the static elimination ball 2. After using it for a period of time, when it is found that the cleaning effect of the sponge brush 15 has deteriorated, due to the telescopic performance of the support spring 9, the sleeve rod 13 can be removed from the mounting hole 12 by pressing the connecting plate 10, thereby facilitating the cleaning of the sponge brush 15, and then it can be installed on the connecting plate 10 in the same way for use.
