It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0024] Refer to Figures 1-5 , a test fixture for a transformer test platform, including a base 1. On both sides of the inner cavity of the base 1, crossbars 3 are provided. The two ends of the crossbars 3 are respectively slidably connected to the inner side walls of the adjacent bases 1. Two round rods 8 are provided on the outer wall of one side of the crossbars 3. One end of the round rods 8 penetrates through the side wall of the adjacent crossbars 3 and is fixedly connected to a round block 5. And an outer ring of the round block 5 is fixedly connected to a telescopic rod 6. The top of the telescopic rod 6 is fixedly connected to a flat plate 9. One side of the flat plate 9 is rotatably connected to a pressing plate 11. Specifically, when a person uses it, the person first places the transformer into the inner cavity of the base 1. In order to ensure the stability of the transformer during the test, the person can move the crossbar 3 through the slider 4 to one side, close to the transformer. The person rotates the round rod 8 so that the damping rod 12 adapts to the outer surface of the transformer to a suitable angle. The person pulls the pressing plate 11, so that the pressing plate 11 drives the damping rod 12 to deform. When the pressing plate 11 is displaced to the top of the transformer, the person releases the hand. Through the action of the spring 13, the bottom of the pressing plate 11 is brought into contact with the surface of the transformer, achieving the effect of clamping and limiting. Then the person tests the transformer through the connection of the wires. Through the structural design, different-sized transformers within a certain range can be stably limited during the test, thus ensuring the accuracy of the test results, effectively reducing the influence of external force interference during the test, and bringing convenience to the users.
[0025] This solution has the following working process:
[0026] When in use, the operator first places the transformer into the inner cavity of the base 1. To ensure the stability of the transformer during the test, the operator can move the crossbar 3 through the slider 4 to one side, close to the transformer. The operator rotates the round rod 8 to make the damping rod 12 fit the outer wall of the transformer at a suitable angle. The operator pulls the pressure plate 11, causing the pressure plate 11 to drive the damping rod 12 to deform. When the pressure plate 11 is displaced to the top of the transformer, the operator releases the hand. Through the action of the spring 13, the bottom of the pressure plate 11 fits the surface of the transformer, achieving the effect of clamping and limiting. Subsequently, the operator tests the transformer through the connection of the wires.
[0027] According to the above working process, it can be known that:
[0028] Through the structural design, transformers of different sizes within a certain range can be stably limited during the test, thus ensuring the accuracy of the test results, effectively reducing the influence of external force interference during the test, and bringing convenience to the users.
[0029] Furthermore, sliders 4 are fixedly connected to both sides of the crossbar 3, and sliding grooves 2 adapted to the sliders 4 are provided on the inner walls of both sides of the base 1. Specifically, through the settings of the sliding grooves 2 and the sliders 4, the stability of the crossbar 3 during displacement is ensured.
[0030] Furthermore, one end of the round rod 8 passes through the side wall of the adjacent crossbar 3 through a bushing and is fixedly connected to one side of the corresponding round block 5. The other end of the round rod 8 is fixedly connected with a handle. One side of the pressure plate 11 and one side of the adjacent flat plate 9 are rotatably connected through a damping rotating shaft 10. Specifically, through the setting of the flat plate 9, a stable supporting force is provided for the pressure plate 11.
[0031] Furthermore, side plates 7 are fixedly connected to both sides of the outer circle of the telescopic rod 6, and damping rods 12 are fixedly connected to the tops of the side plates 7. The tops of the damping rods 12 are fixedly connected to the bottoms of the adjacent flat plates 9. Specifically, through the setting of the damping rods 12, in cooperation with the spring 13, the telescopic rod 6 can continuously receive the action force of the spring 13.
[0032] Furthermore, a spring 13 is installed on the outer circle of the damping rod 12. One end of the spring 13 is fixedly connected to the top of the adjacent side plate 7, and the other end of the spring 13 is fixedly connected to the bottom of the adjacent flat plate 9. Specifically, through the setting of the side plate 7, the stability of the damping rod 12 is ensured.
[0033] Furthermore, the two corresponding round rods 8 are symmetrically distributed on both sides of the crossbar 3. Specifically, through the setting of the damping rotating shaft 10, the pressure plate 11 has a certain limiting effect during rotation adjustment.
[0034] In summary: When in use, the user first places the transformer into the inner cavity of the base 1. To ensure the stability of the transformer during the test, the user can move the cross bar 3 through the slider 4 to one side, close to the transformer. The user rotates the round rod 8 to make the damping rod 12 adapt to the outer wall of the transformer at a suitable angle. The user pulls the pressing plate 11, causing the pressing plate 11 to drive the damping rod 12 to deform. When the pressing plate 11 is displaced to the top of the transformer, the user releases the hand. Through the action of the spring 13, the bottom of the pressing plate 11 is brought into contact with the surface of the transformer, achieving the effect of clamping and limiting. Subsequently, the user tests the transformer through the connection of the wire. Through the settings of the chute 2 and the slider 4, the stability of the cross bar 3 during displacement is ensured. Through the setting of the flat plate 9, a stable supporting force is provided for the pressing plate 11. Through the setting of the damping rod 12, in cooperation with the spring 13, the telescopic rod 6 can continuously receive the action of the spring 13. Through the setting of the side plate 7, the stability of the damping rod 12 is ensured. Through the setting of the damping rotating shaft 10, the pressing plate 11 has a certain limiting effect during rotation adjustment. Through the structural design, transformers of different sizes within a certain range can be stably limited during the test, thus ensuring the accuracy of the test results, effectively reducing the influence of external force interference during the test, and bringing convenience to the users.
