Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-7This utility model provides a technical solution: a voltage transformer detection device, including a voltage transformer detector housing 2, a voltage transformer detector body 6 disposed inside the voltage transformer detector housing 2, a voltage transformer detector cover 1 rotatably connected to the upper end of the voltage transformer detector housing 2 via a hinge, a rectangular slide groove 15 opened at the rear end of the voltage transformer detector housing 2, a sliding sealing door 7 slidably connected within the rectangular slide groove 15, a docking clip 9 fixedly connected to the left end of the sliding sealing door 7, a toggle block 8 fixedly connected to the rear end of the sliding sealing door 7, and a fixing assembly disposed at the rear end of the voltage transformer detector housing 2, the fixing assembly including a docking clip box 10, a sliding pull rod 11, a fixed push plate 13, two springs 16, three sliding pull rods 14, and a triangular clip 12. The device is fixedly connected to the rear end of the voltage transformer detector housing 2. The sliding pull rod 11 is slidably connected to the docking card box 10. The fixed push plate 13 is fixedly connected to the front end of the sliding pull rod 11. Two springs 16 are fixedly connected to the rear end of the fixed push plate 13. Three sliding pull rods 14 are fixedly connected to the front end of the fixed push plate 13. The triangular block 12 is fixedly connected to the front end of the three sliding pull rods 14. This design solves the problem that in the original device, during the carrying process, external dust and water can easily enter the voltage transformer detector body 6 through the heat dissipation port of the voltage transformer detector body 6, causing blockage or corrosion of the heat dissipation port of the voltage transformer detector body 6, thereby affecting the heat dissipation effect of the voltage transformer detector body 6 and causing the voltage transformer detector body 6 to easily overheat.

[0024] As the first embodiment of this utility model: the triangular locking block 12 and the docking strip 9 cooperate with each other. When the docking strip 9 slides into the docking box 10, the triangular locking block 12 will lock the docking strip 9 under the elastic force of the spring 16, so that the sliding sealing door 7 can block the heat dissipation area of ​​the voltage transformer detector body 6. A sealing strip 17 is fixedly connected to the left end of the sliding sealing door 7. The sealing strip 17 cooperates with the voltage transformer detector box 2. The sealing strip 17 installed on the left end of the sliding sealing door 7 seals the square hole at the rear end of the voltage transformer detector box 2 to prevent external dust and water from entering the voltage transformer detector body 6. A fixing knob 5 is rotatably connected to the front end of the voltage transformer detector box cover 1, and a rotating pull rod 4 is rotatably connected to the front end of the voltage transformer detector box body 2. The fixing knob 5 installed at the front end of the voltage transformer detector box cover 1 can fix the voltage transformer detector box cover 1 and the voltage transformer detector box body 2, making it convenient for users to fix the voltage transformer detector box cover 1 and the voltage transformer detector box body 2 in place. The rotating pull rod 4 located at the front end of the voltage transformer detector box body 2 allows users to easily lift and move the voltage transformer detector box body 2. The sliding sealing door 7 has a rubber layer on its surface, which can seal the square hole at the rear end of the voltage transformer detector box body 2 to prevent external dust from entering the voltage transformer detector body 6.

[0025] As a second embodiment of this utility model: When the voltage transformer detector body 6 needs to be used, first rotate the fixing knob 5 to loosen the voltage transformer detector box cover 1, then open the voltage transformer detector box cover 1 to expose the voltage transformer detector body 6. Then pull the sliding lever 11 to move it outward, so that the triangular locking block 12 releases the docking locking strip 9. Then pinch the toggle lever 8 to drive the sliding sealing door 7 to slide to the right, exposing the heat dissipation vent of the voltage transformer detector body 6. When the user is using the voltage transformer detector body 6, the voltage transformer detector... The heat dissipation vent of the detector body 6 can dissipate heat inside the voltage transformer detector body 6. When the voltage transformer detector body 6 is idle, the sliding sealing door 7 can be moved to the left by pinching the toggle lever 8, so that the docking strip 9 slides into the docking card box 10. The docking strip 9 pushes the triangular block 12 outward. When the triangular block 12 is aligned with the square hole of the docking strip 9, the triangular block 12 is locked in the docking strip 9 under the elastic force of the spring 16, thereby sealing the square hole at the rear end of the voltage transformer detector box 2 with the sliding sealing door 7.
