[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, the utility model provides a technical solution: a relay performance testing device, comprising a body 1, a cover plate 2 being slidably connected to one side of the outer wall of the body 1, and the body 1 is located on the inner side of the cover plate 2, one side of the outer wall of the body 1 is connected through the inner side of the cover plate 2, and the inner side of the cover plate 2 is slidably connected to the body 1, a winding roller 3 is rotatably connected to one side of the inner side of the body 1, and a detection wire 301 is sleeved on the outer wall of the winding roller 3, the center of the outer wall of the detection wire 301 passes through one side of the inner wall of the body 1, and the inner side of the body 1 is slidably connected to the center of the outer wall of the detection wire 301, the outer wall of the detection wire 301 is fixedly connected to the negative electrode clamp 4 at one end away from the winding roller 3, and the outer wall of the other end of the detection wire 301 is fixedly connected to the positive electrode clamp 5, the bottom end of the outer wall of the winding roller 3 is fixedly connected to a toothed disc 302, and the top side of the toothed disc 302 is rotatably connected to a limiting tooth 303.

[0027] When storing the device, the user only needs to turn the adjustment knob 204 located on the outer wall of the cover 2. This action will drive the threaded rod 203 to rotate. As the threaded rod 203 rotates, the slide rod 202 and the body 1 will slide horizontally along the inner wall of the slide groove 201 through the outer wall thread. The top of the driving block 205 is fixedly connected to the center of the bottom surface of the body 1. The rotation of the threaded rod 203 further guides the body 1 to slide along the slide groove 201, and finally stores it in the inner center of the cover 2. When the detection wire 301 needs to be stored, the winding knob 308 is pulled out to the outside of the device, and the limiting ball 3011 is locked in one of the limiting grooves 3 When the limiting ball 3011 reaches one of the limiting grooves 305 near the hollow positioning frame 306, the limiting ball 3011 is no longer under the pressure from the inner wall of the limiting tooth 303. The limiting spring 3010 can push the limiting ball 3011 into the limiting groove 305 to limit the winding knob 308. At the same time, the positioning block 309 on the outer wall of the winding knob 308 is disengaged from the positioning groove 307 on the outer wall of the hollow positioning frame 306. The winding knob 308 loses the restriction from the hollow positioning frame 306. The cam 308 is able to rotate, and the winding knob 308 drives the limiting tooth 303 to rotate through the insert block 304 at the inner center of the limiting tooth 303. Since the bottom side of the limiting tooth 303 is meshed with the top side of the toothed disc 302, the winding knob 308 is meshed with the toothed disc 302 through the limiting tooth 303, driving the winding roller 3 to rotate. After the detection wire 301 is wound, the winding knob 308 is pressed toward the side of the machine body 1, so that the positioning block 309 on the outer wall side of the winding knob 308 is embedded in the positioning groove 307 on the inner wall side of the hollow positioning frame 306, and the position of the winding knob 308 is limited by the limiting ball 3011 to fix the limit. The teeth 303, the toothed disc 302 and the winding roller 3 ensure the stability and safety of the detection wire 301 during use. When the winding knob 308 is pressed toward the side of the body 1, the positioning block 309 on one side of its outer wall is tightly combined with the positioning groove 307 on one side of the outer wall of the hollow positioning frame 306, thereby locking the limit teeth 303, the toothed disc 302 and the winding roller 3, so that the detection wire 301 can be properly stored when not in use, preventing the wire from being loose and entangled, reducing the usage space, and also reducing the risk of damage to the wire. In addition, the mechanism is simple and easy to operate, which is convenient for users to quickly complete the wire retraction and release action, thereby improving work efficiency.

[0028] like Figure 1-2As shown, a plurality of sliding grooves 201 are provided at the bottom end of the inner wall of the cover plate 2, and a sliding rod 202 is slidably connected to one end of the inner wall of the sliding groove 201, and the top of the outer wall of the sliding rod 202 is fixedly connected to one side of the bottom surface of the body 1, and the sliding rod 202 is located on both sides of the bottom surface of the body 1, and one end of the outer wall of the sliding rod 202 is connected to one end of the inner wall of the sliding groove 201, and both sides of the inner wall of the sliding rod 202 are slidably connected to one end of the inner wall of the sliding groove 201, and the bottom end of the inner wall of the cover plate 2 is rotatably connected to a threaded rod 203, and one end of the outer wall of the threaded rod 203 penetrates the inner wall of one side of the cover plate 2 and is fixedly connected to the adjusting knob 204, and a driving block 205 is fixedly connected at the center of the bottom surface of the body 1, and the driving block 205 is located at one end of the outer wall of the threaded rod 203, one end of the outer wall of the threaded rod 203 penetrates the outer wall of one side of the driving block 205, and one end of the outer wall of the threaded rod 203 is rotatably connected to the inner center of the driving block 205 through a thread.

[0029] When the device is to be stored, the user only needs to turn the adjusting knob 204 on the outer wall of the cover plate 2. This action will drive the threaded rod 203 to rotate. As the threaded rod 203 rotates, the sliding rod 202 threaded rod 203 will push the sliding rod 202 and the body 1 to slide horizontally along the inner wall of the sliding groove 201 through the outer wall thread. The top of the driving block 205 is fixedly connected to the center of the bottom surface of the body 1. The rotation of the threaded rod 203 further guides the body 1 to slide along the sliding groove 201, and finally stores it in the inner center of the cover plate 2. In this way, the device greatly reduces the possibility of moisture penetrating into the body 1 by making the cover plate 2, threaded rod 203 and sliding rod 202 cooperate with each other, effectively ensuring the safety of the device when it is used next time. When the device needs to be used, the user can smoothly and quickly slide the body 1 outward along the sliding groove 201 by rotating the adjusting knob 204 in the opposite direction, so that the device is quickly ready and easy to operate.

[0030] like Figure 1 、 Figure 3 and Figure 4As shown, the inner center of the limiting tooth 303 is fixedly connected to an insert block 304, and the inner center of the limiting tooth 303 is provided with a plurality of limiting grooves 305, one side of the outer wall of the body 1 is fixedly connected to a hollow positioning frame 306, and the outer wall of the hollow positioning frame 306 away from the limiting tooth 303 is provided with a plurality of positioning grooves 307, the outer wall of the hollow positioning frame 306 away from the limiting tooth 303 is slidably connected to a winding knob 308, and one side of the outer wall of the winding knob 308 is fixedly connected to a plurality of positioning blocks 309, and one side of the outer wall of the positioning block 309 is connected to the positioning groove 307. 07 The centers of the inner walls are in contact with each other, one end of the outer wall of the winding knob 308 is connected through the inner center of the hollow positioning frame 306, and one end of the outer wall of the winding knob 308 is in contact with the inner center of the limiting tooth 303, the insert block 304 is slidably connected to the inner end of the winding knob 308, and a plurality of limiting springs 3010 are fixedly connected to the inner end of the winding knob 308, and one end of the outer wall of the limiting spring 3010 is fixedly connected to the limiting ball 3011, and one side of the outer wall of the limiting ball 3011 is in contact with the inner wall of the limiting groove 305.

[0031] When the detection wire 301 needs to be stored, the winding knob 308 is pulled out of the device, and the limiting ball 3011 is pushed into the winding knob 308 by the arc surface inside one of the limiting grooves 305, and the limiting ball 3011 compresses the limiting spring 3010. When the limiting ball 3011 comes to one of the limiting grooves 305 close to the hollow positioning frame 306, since the limiting ball 3011 has no pressure from the inner wall of the limiting tooth 303, the limiting ball 3011 is pushed into the winding knob 308 by the elasticity of the limiting spring 3010. When the cam 308 is in the closed position, the cam 308 is in the closed position, and the cam 308 is in the closed position, so the cam 308 is in the closed position. The limit teeth 303 and the toothed disc 302 are meshed with each other, driving the winding roller 3 to rotate. After the detection wire 301 is wound, the winding knob 308 is pressed toward the side of the body 1, so that the positioning block 309 on the outer wall of the winding knob 308 is embedded in the positioning groove 307 on the inner wall of the hollow positioning frame 306, and the position of the winding knob 308 is limited by the limiting ball 3011, so that the limit teeth 303, the toothed disc 302 and the winding roller 3 can be fixed, thereby ensuring the stability and safety of the detection wire 301 during use. When the winding knob 308 is pressed toward the side of the body 1, the positioning block 309 on one side of its outer wall is tightly combined with the positioning groove 307 on one side of the outer wall of the hollow positioning frame 306, thereby locking the limit teeth 303, the toothed disc 302 and the winding roller 3, so that the detection wire 301 can be properly stored when not in use, preventing the wire from loosening and entanglement, reducing the usage space, and also reducing the risk of wire damage. In addition, the mechanism is simple and easy to operate, which facilitates users to quickly complete the wire retraction and release actions, thereby improving work efficiency.

[0032] Working principle: When storing the device, the user only needs to turn the adjustment knob 204 located on the outer wall of the cover 2. This action will drive the threaded rod 203 to rotate. As the threaded rod 203 rotates, the slide rod 202 and the body 1 will slide horizontally along the inner wall of the slide groove 201 through the outer wall thread. The top of the driving block 205 is fixedly connected to the center of the bottom surface of the body 1. The rotation of the threaded rod 203 further guides the body 1 to slide along the slide groove 201, and finally it is stored in the inner center of the cover 2. When it is needed When the detection wire 301 is to be stored, the winding knob 308 is pulled out of the device, and the limiting ball 3011 is pushed into the winding knob 308 by the arc surface inside one of the limiting grooves 305, and the limiting ball 3011 compresses the limiting spring 3010. When the limiting ball 3011 comes to one of the limiting grooves 305 close to the hollow positioning frame 306, since the limiting ball 3011 has no pressure from the inner wall of the limiting tooth 303, the limiting ball 3011 is pushed into the winding knob 308 by the elasticity of the limiting spring 3010. The inner limit groove 305 limits the winding knob 308. At the same time, the positioning block 309 on the outer wall of the winding knob 308 is disengaged from the positioning groove 307 on the outer wall of the hollow positioning frame 306. The winding knob 308 loses the restriction from the hollow positioning frame 306 and can rotate. The winding knob 308 drives the limiting tooth 303 to rotate through the insert block 304 at the center of the limiting tooth 303. Since the bottom side of the limiting tooth 303 is engaged with the top side of the toothed disc 302, the winding knob 308 is The limiting teeth 303 and the toothed disc 302 engage with each other, driving the winding roller 3 to rotate. After the detection wire 301 is wound, the winding knob 308 is pressed toward the side of the machine body 1, so that the positioning block 309 on the outer wall side of the winding knob 308 is embedded in the positioning groove 307 on the inner wall side of the hollow positioning frame 306, and the position of the winding knob 308 is limited by the limiting ball 3011, so that the limiting teeth 303, the toothed disc 302 and the winding roller 3 can be fixed, thereby ensuring the stability and safety of the detection wire 301 during use.
