[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figure 1 The present invention provides a power supply test fixture, comprising: a base plate 1 and a power supply body 3, wherein a test structure 2 is provided on the upper surface of the base plate 1.

[0030] In the embodiments of this utility model, please refer to Figures 2 to 6The test structure 2 includes a fixed plate 201 and a fixed frame 220. The fixed plate 201 is fixedly connected to the base plate 1, and the fixed frame 220 is fixedly connected to the base plate 1. A second cylinder 224 is fixedly connected to the upper surface of the fixed frame 220. The output end of the second cylinder 224 is slidably connected to the fixed frame 220. A pressing plate 221 is fixedly connected to the output end of the second cylinder 224. Two positioning rods 223 are fixedly connected to the upper surface of the pressing plate 221, and the two positioning rods 223 are slidably connected to the fixed frame 220. Two positioning grooves 218 and two limiting holes 217 are opened on the inner wall of the fixed plate 201. Connecting plates 219 are slidably connected to the inner wall of the positioning grooves 218. Positioning plates 226 are fixedly connected to the upper surface of the two connecting plates 219. Connecting grooves 225 are opened on the inner wall of the positioning plates 226, and the connecting grooves 225 are slidably connected to the power supply body 3. A fixing post 212 is fixedly connected to the upper surface of the fixed plate 201. A rotating plate 213 is rotatably connected to the arc surface of the fixed plate 201. A rod 215 is slidably connected to the inner wall of the rotating plate 213. The rod 215 is slidably connected to the limiting hole 217. A spring 214 is sleeved on the arc surface of the rod 215. The two ends of the spring 214 are fixedly connected to the rod 215 and the rotating plate 213, respectively. A connecting plate 202 is fixedly connected to one side of the fixed plate 201. A limiting groove 203 is formed on the inner wall of the connecting plate 202. A moving block is slidably connected to the inner wall of the limiting groove 203. 204. A lead screw 205 is rotatably connected to the inner wall of the limiting groove 203. The lead screw 205 is rotatably connected to the connecting plate 202 and threadedly connected to the moving block 204. A connecting post 210 is fixedly connected to one end of the lead screw 205. A connecting block 207 is fixedly connected to the side of the moving block 204 away from the fixed plate 201. A first cylinder 208 is fixedly connected to the upper surface of the connecting block 207. A test head 209 is fixedly connected to the output end of the first cylinder 208. This design allows personnel to easily adjust the position of the test head 209 and easily replace the positioning plate 226 when testing other power supply bodies 3, thereby improving work efficiency and increasing the adaptability of the power supply test fixture. Two limiting rods 206 are fixedly connected to the inner wall of the limiting groove 203 and are slidably connected to the moving block 204. The limiting rod 206 can limit the movement block 204, preventing it from shifting during sliding on the inner wall of the limiting groove 203. The connecting column 210 has several anti-slip grooves 211 evenly distributed on its arc surface. These grooves increase friction between the user's hand and the connecting column 210, preventing slippage during rotation. A pull ring 216 with a circular cross-section is fixedly connected to the end of the insertion rod 215 away from the limiting hole 217.The pull ring 216 facilitates the movement of the insertion rod 215, improving operational convenience. A protective pad 222 is fixedly connected to the lower surface of the extrusion plate 221, and the protective pad 222 is slidably connected to the fixing frame 220. The protective pad 222 protects the power supply body 3, preventing direct contact between the power supply body 3 and the extrusion plate 221. The moving block 204 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the moving block 204 during short-term use.

[0031] The working principle of the power supply test fixture provided by this utility model is as follows: When personnel need to test power supply bodies 3 of other sizes, they can first use the pull ring 216 to move the insertion rod 215 away from the limiting hole 217. The pull ring 216 facilitates the movement of the insertion rod 215, improving the ease of operation. Then, the insertion rod 215 drives the spring 214 to stretch until the insertion rod 215 slides out of the inner wall of the limiting hole 217. Then, the personnel rotate the rotating plate 213, causing the rotating plate 213 to move away from the positioning plate 226. The rotating plate 213 drives the spring 214 and the insertion rod 215 to move away from the positioning plate 226 until the rotating plate 213 moves away from the connecting plate 2. The upper surface of 19 is then moved by the operator, who moves the positioning plate 226 upwards. The positioning plate 226 drives the two connecting plates 219 upwards until the connecting plates 219 slide out of the inner wall of the positioning groove 218. After the operator replaces the positioning plate 226 with a suitable one, the operator rotates the rotating plate 213 towards the positioning plate 226 until the spring 214 rebounds, causing the insertion rod 215 to slide into the inner wall of the limiting hole 217. Then the operator rotates the connecting column 210. The anti-slip groove 211 on the arc surface of the connecting column 210 increases the friction between the operator's hand and the connecting column 210, preventing slippage during rotation. During the process, slippage occurs, and then the connecting column 210 drives the lead screw 205 to rotate. The lead screw 205 drives the moving block 204 to slide on the arc surface of the two limit rods 206. The limit rods 206 can limit the moving block 204 to prevent it from misaligning during sliding on the inner wall of the limit groove 203. Then, the moving block 204 drives the connecting block 207 to move, and the connecting block 207 drives the first cylinder 208 to move. The output end of the first cylinder 208 drives the test head 209 to move until the test head 209 corresponds to the test port reserved on the newly replaced positioning plate 226. When personnel need to test the power supply body 3, they can first slide the power supply body 3 into the positioning plate 226. The inner wall is then inspected. The operator activates the second cylinder 224, whose output moves the extrusion plate 221 downwards. The extrusion plate 221 then moves the protective pad 222 downwards. The protective pad 222 protects the power supply body 3, preventing direct contact between the power supply body 3 and the extrusion plate 221, until the protective pad 222 comes into contact with the power supply body 3, thus limiting its movement. Then, the operator activates the first cylinder 208, whose output moves the test head 209 closer to the power supply body 3, until the test head 209 is inserted into the interior of the power supply body 3 for testing. The moving block 204 is made of stainless steel, which has high strength and good wear resistance.This prevents deformation of the moving block 204 during short-term use.
