[0002] An electrostatic detection device is a device used to detect and measure electrostatic charges or electric field strength. Electrostatic electricity is a phenomenon caused by an imbalance of charges on the surface of an object. Due to the presence of electrostatic charges, many problems can occur, such as electrostatic discharge, fire risks, electronic device failures, etc. Currently, various electronic devices are installed on vehicles, so electrostatic test operations are required during the production of electronic devices used in vehicles;

[0003] The existing electrostatic detection devices are usually EDS detection devices composed of a discharge gun and a high-voltage generator. The discharge gun and the high-voltage generator are connected through a connecting wire and a connecting plug. However, there is no insurance device for the connection between the two. During use, the connection between the discharge gun and the high-voltage generator may become loose due to the dragging of the staff, resulting in deviation of the measurement results. Poor contact may also cause electric leakage, forming a safety hazard. Summary of the Utility Model

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1-5 shown, an electrostatic test device for vehicle inspection includes a discharge gun 1. A connecting wire 2 is connected to the lower end of the handle of the discharge gun 1. One end of the connecting wire 2 is movably connected to a high-voltage generator 3 through a connecting plug 4. An insurance structure 5 is arranged outside the connecting plug 4;

[0025] The insurance structure 5 includes three plugs 7. The three plugs 7 are fixedly installed outside the connecting plug 4. Snap 9 is movably installed inside each of the three plugs 7. The snap 9 is in a "U" shape. Both ends of the snap 9 penetrate through the plug 7. Two springs 8 are fixedly installed at the lower part of the snap 9. One end of each of the two springs 8 is fixedly connected to the plug 7.

[0026] In this embodiment, three jacks are provided at the connection between the high-voltage generator 3 and the connecting plug 4, and the jacks are adaptively matched with the plugs 7. One end of the "U" shape of the snap 9 is wedge-shaped. Grooves are provided in each of the three jacks, and the grooves are adaptively matched with the wedge-shaped end of the snap 9.

[0027] In order to prevent the connecting plug 4 from being accidentally pulled out during use, when the connecting plug 4 is inserted into the high-voltage generator 3, the plug 7 is inserted into the jack of the high-voltage generator 3. When the snap 9 enters the jack, it is snapped into the groove inside the jack under the action of the spring 8. The front end of the snap 9 is wedge-shaped, so that the plug 7 is fixed in the jack. Press the other end of the snap 9, and the snap 9 retracts into the plug 7 under the action of the spring 8, so that the connecting plug 4 can be smoothly pulled out.

[0028] In this embodiment, a protective structure 6 is provided on the outside of the gun head 10 of the discharge gun 1. The protective structure 6 includes a protective sleeve 12 and a protective cover 11. The protective sleeve 12 is slidably installed on the outside of the gun head 10. An external thread 14 is provided at the end of the protective sleeve 12. The inner wall of the protective cover 11 is provided with an internal thread, which is adaptively matched with the external thread 14 at the end of the protective sleeve 12.

[0029] The protective cover 11 is connected to the protective sleeve 12 by threads. When the discharge gun 1 is not in use, the gun head 10 can be protected inside the protective sleeve 12 to isolate the gun head 10 from the outside world, thereby preventing the gun head 10 from being damaged or rusted by the outside world, resulting in inaccurate detection results.

[0030] In this embodiment, a limiting block 15 is fixedly mounted on the bottom end of the protective sleeve 12 , a through slot 13 is provided at the connection between the discharge gun 1 and the gun head 10 , and the through slot 13 is adaptively matched with the limiting block 15 .

[0031] When the discharge gun 1 is used, the protective cover 12 is put into the through groove 13 inside the discharge gun 1 to prevent the protective cover 12 from affecting the detection work of the discharge gun 1. The friction between the limit block 15 and the through groove 13 is greater than the gravity of the protective cover 12, which can prevent the protective cover 12 from sliding under non-human operation.

[0032] In this embodiment, two fixing buckles 16 are fixedly installed on the outside of the protective sleeve 12 near the external thread 14. The fixing buckles 16 are composed of two elastic materials and a magnetic sheet is provided at the inner end. The elastic material is made of elastic plastic.

[0033] In this embodiment, two fixing columns 17 are provided at the end of the discharge gun 1 , and through holes are provided at the ends of the fixing columns 17 , and the diameter of the through holes is greater than the diameter of the magnetic attraction sheet at the end of the fixing buckle 16 .

[0034] After the protective cover 12 is put into the discharge gun 1, in order to prevent the protective cover 12 from slipping out, a fixing buckle 16 and a fixing column 17 are provided to interact with each other. The fixing buckle 16 is composed of two plastic sheets and has flexibility. A magnetic sheet is provided at the end of the plastic sheet. The plastic sheets adsorbed together are pulled apart and aligned with the through hole of the fixing column 17. Then, the plastic sheets are adsorbed together and stuck in the through hole of the fixing column 17, so that the protective cover 12 is fixed and cannot be moved.

[0035] In this embodiment, a non-slip grip pad is provided at the handle of the discharge gun 1, and a handle is installed on the upper part of the high voltage generator 3.

[0036] It should be noted that the utility model is an electrostatic test device for automobile inspection. When in use, the discharge gun 1 and the high-voltage generator 3 are connected through the connecting plug 4. The plug 7 outside the connecting plug 4 is inserted into the jack of the high-voltage generator 3. When the buckle 9 enters the jack, it is clamped into the groove inside the jack under the action of the spring 8. The front end of the buckle 9 is wedge-shaped, so that the plug 7 is fixed in the jack. Press the other end of the buckle 9, and the buckle 9 retracts the plug 7 under the action of the spring 8, so that the connecting plug 4 can be smoothly pulled out;

[0037] When using the discharge gun 1, first unscrew the protective cover 11 of the protective cover 12 outside the gun head 10, and then put the protective cover 12 into the discharge gun 1. The fixing buckle 16 is composed of two plastic sheets and has flexibility. A magnetic sheet is arranged at the end of the plastic sheet. The plastic sheets adsorbed together are pulled apart and aligned with the through hole of the fixing column 17. Then, the plastic sheets are adsorbed together and stuck in the through hole of the fixing column 17, so that the protective cover 12 is fixed and cannot be moved.
