[0007] As mentioned above, the protective layer is opened between the test chamber and the device body, the protective layer is filled with ceramic fiber material, the bottom of the test chamber is fixed to the device body, the fixing seat is fixedly connected to the bottom end of the test chamber, and the fixing seat is symmetrically distributed on both sides of the placement seat.

[0008] As mentioned above, the card slot and the card block are connected by a card engagement, the fixed tooth block is fixed to the inner walls on both sides of the fixed plate, the driven gear and the fixed tooth block are meshed, the guide rod and the slide are connected by a sliding connection, and the slide is opened at the upper and lower ends of the fixed plate.

[0009] As mentioned above, the driven gear and the guide rod are rotationally connected, the connecting block is connected to the driven gear through the guide rod, the connecting block forms a telescopic structure with the fixed plate through the cooperation between the guide rod, the slideway, the driven gear and the fixed gear block, and the connecting block is movably connected to the inside of the fixed plate in the shape of a "convex" character.

[0012] Compared with the prior art, this cylindrical battery testing tool has the following beneficial effects:

[0013] 1. The utility model firstly prevents sparks, high temperature or other potential dangers that may occur during the test from causing damage to the test personnel and the device body through a protective layer.

When the clamping seat clamps the battery, the fixed outer ring can also provide certain support and fixing effects to ensure that the battery remains stable during the test.

[0023] According to the overall structure of the device, safe and stable testing of cylindrical batteries is achieved. The ceramic fiber material filling of the protective layer 101 not only ensures the safety of the testing process, but also improves the durability of the device. The placement seat 103 inside the test chamber 102 provides a stable testing environment for the battery. Then, through the meshing transmission of the driven gear 205 and the fixed gear block 204, the linkage block 208 can accurately realize the telescopic function, so that the internal clamping seat 305 can be in close contact with the battery, ensuring the accuracy of the test. The anti-slip pad 306 on the inner wall of the clamping seat 305 effectively prevents the battery from shaking during the test and ensures the stability of the test. In addition, the design of the telescopic plate 304 enables the clamping seat 305 to adapt to batteries of different diameters, greatly improving the flexibility of the test.

[0024] like Figure 1-4 As shown, the protective layer 101 is provided between the test chamber 102 and the device body 1, and the protective layer 101 is filled with ceramic fiber material. The bottom of the test chamber 102 is fixed to the device body 1, and the fixing seat 2 is fixedly connected to the bottom end of the test chamber 102. The fixing seat 2 is symmetrically distributed on both sides of the placement seat 103. The card slot 201 and the card block 202 are engaged with each other, and the fixed tooth block 204 is fixed to the inner walls of both sides of the fixed plate 203. The driven gear 205 and the fixed tooth block 204 are meshed with each other. There is a sliding connection between the guide rod 206 and the slide 207, the slide 207 is opened at the upper and lower ends of the fixed plate 203, the driven gear 205 and the guide rod 206 are rotationally connected, the connecting block 208 is connected to the driven gear 205 through the guide rod 206, the connecting block 208 forms a telescopic structure with the fixed plate 203 through the cooperation between the guide rod 206, the slide 207, the driven gear 205 and the fixed gear block 204, and the connecting block 208 is in the shape of a "convex" and is movably connected to the inside of the fixed plate 203.

[0025] The protective layer 101 is used to prevent sparks, high temperatures or other potential dangers that may occur during the test from causing damage to the tester and the device body 1. Since the protective layer 101 is filled with ceramic fiber material, it not only has good heat insulation performance, but also can effectively resist chemical corrosion and mechanical impact. The placement seat 103 inside the test chamber 102 is used to place the cylindrical battery to be tested. The fixed seat 2 is connected by the card slot 201 and the card block 202, so that it is convenient for disassembly and maintenance. Then the meshing transmission between the fixed tooth block 204 and the driven gear 205 is the key to realizing the telescopic function of the linkage block 208. When the driven gear 205 is pushed by an external force, it will rotate along the tooth groove of the fixed tooth block 204, thereby driving the linkage block 208 to slide on the guide rod 206. Due to the limitation of the slideway 207, the linkage block 208 can only move up and down inside the fixed plate 203, realizing the telescopic function. In actual applications, the position of the linkage block 208 can be adjusted according to the test requirements, thereby adjusting the distance between the internal clamping seat 305 and the battery to make its contact closer.

[0026] like Figure 1-4 As shown, the fixed outer ring 303 is fixed to the outer wall of the placement rod 301 through the connecting plate 302, the fixed outer ring 303 is arranged in a semicircular shape, a group of fixed outer rings 303 and the vertical center line of the placement seat 103 coincide with each other, the clamping seat 305 forms a telescopic structure with the fixed outer ring 303 through the telescopic plate 304, and the anti-slip pad 306 is evenly distributed on the inner wall of the clamping seat 305, and the anti-slip pad 306 is arranged for silicone material.

[0027] When the cylindrical battery is placed in the placement seat 103, the clamping seat 305 begins to move towards the battery under the action of the telescopic plate 304 and the linkage block 208. At the same time, the inner wall of the clamping seat 305 is evenly distributed with anti-skid pads 306. The anti-skid pads 306 are made of silicone material, which can not only ensure that the surface of the battery is not damaged when clamping it, but also ensure that the battery is firmly fixed to prevent shaking during the test. The telescopic plate 304 enables the clamping seat 305 to further adjust the distance from the battery, so that the clamping seat 305 can better adapt to batteries of different diameters. When the clamping seat 305 clamps the battery, the fixed outer ring 303 can also provide certain support and fixing effects to ensure that the battery remains stable during the test.

[0028] Working principle: First, the protective layer 101 is used to prevent sparks, high temperatures or other potential dangers that may occur during the test from causing damage to the tester and the device body 1. Since the protective layer 101 is filled with ceramic fiber material, it not only has good heat insulation performance, but also can effectively resist chemical corrosion and mechanical impact. The placement seat 103 inside the test chamber 102 is used to place the cylindrical battery to be tested. The fixing seat 2 is connected by the card slot 201 and the card block 202, which makes it easy to disassemble and repair. Then the fixed tooth block 204 and the The meshing transmission between the moving gears 205 is the key to realizing the telescopic function of the linkage block 208. When the driven gear 205 is pushed by an external force, it will rotate along the tooth groove of the fixed tooth block 204, thereby driving the linkage block 208 to slide on the guide rod 206. Due to the limitation of the slideway 207, the linkage block 208 can only move up and down inside the fixed plate 203, realizing the telescopic function. In actual application, the position of the linkage block 208 can be adjusted according to the test requirements, thereby adjusting the distance between the internal clamping seat 305 and the battery to make the contact closer.

[0029] When the cylindrical battery is placed in the placement seat 103, the clamping seat 305 begins to move towards the battery under the action of the telescopic plate 304 and the linkage block 208. At the same time, the inner wall of the clamping seat 305 is evenly distributed with anti-skid pads 306. The anti-skid pads 306 are made of silicone material, which can not only ensure that the surface of the battery is not damaged when clamping it, but also ensure that the battery is firmly fixed to prevent shaking during the test. The telescopic plate 304 enables the clamping seat 305 to further adjust the distance from the battery, so that the clamping seat 305 can better adapt to batteries of different diameters. When the clamping seat 305 clamps the battery, the fixed outer ring 303 can also provide certain support and fixing effects to ensure that the battery remains stable during the test.
