[0027] Figure 1-4 The following is a schematic diagram of a high-voltage explosion-proof device according to the present invention. Figure 1-Figure 4 A high-voltage explosion-proof detection device of this embodiment includes a base 100 , a splint 200 , an explosion-proof box 300 and a limit assembly 400 .

[0028] A first slide groove 110 is provided at the top of the base 100, and a forward and reverse threaded rod 120 is rotatably connected inside the first slide groove 110. One end of the forward and reverse threaded rod 120 extends out of the side wall of the base 100 and is installed with a first knob 130. A second slide groove 150 is provided at the top of the base 100, and a threaded rod 160 is rotatably connected to the inner wall of the second slide groove 150. One end of the threaded rod 160 extends out of the side wall of the base 100 and is installed with a second knob 170. A T-slot 180 is provided at the top of the base 100, and a T-plate 340 is installed at the bottom of the explosion-proof box 300, and the T-plate 340 is located inside the T-slot 180.

[0029] There are two splints 200 symmetrically located on the top of the base 100, and the bottom of the splint 200 extends into the first slide groove 110. A first threaded hole 210 is provided on the side wall of the splint 200, and the positive and negative threaded rod 120 rotates and passes through the first threaded hole 210. A guide rod 140 is installed inside the first slide groove 110, and a guide hole 220 is provided on the side wall of the splint 200. The guide rod 140 passes through the guide hole 220, and an anti-slip pad 230 is installed on the inner wall of the splint 200. By placing the workpiece between the two splints 200 and rotating the first knob 130 to drive the positive and negative threaded rod 120 to rotate, when the positive and negative threaded rod 120 rotates, the screw structure is used to push the two splints 200 close to each other and clamp the workpiece. The anti-slip pad 230 converts the hard contact between the splint 200 and the workpiece into elastic contact, preventing the splint 200 from causing damage to the workpiece and increasing the friction between the splint 200 and the workpiece.

[0030] The explosion-proof box 300 slides on the top of the base 100, and the inner wall of the explosion-proof box 300 is wrapped with a layer of polyurethane foam. An observation window 310 is provided on the side wall of the explosion-proof box 300, and explosion-proof glass is provided inside the observation window 310. A fixing plate 320 is installed at the bottom of the explosion-proof box 300, and a second threaded hole 330 is provided on the side wall of the fixing plate 320. The threaded rod 160 rotates through the second threaded hole 330. After clamping the workpiece with the clamping plate 200, the second knob 170 is rotated to drive the threaded rod 160 to rotate. When the threaded rod 160 rotates, the screw structure is used to push the fixing plate 320 and the explosion-proof box 300 to move toward the workpiece until the workpiece is located inside the explosion-proof box 300. The polyurethane foam inside the explosion-proof box 300 plays an explosion-proof role during detection.

[0031] The limit assembly 400 includes a fixed frame 410 installed on the side wall of the base 100, a slide 420 slidingly located inside the fixed frame 410, a spring 430 installed on the side wall of the slide 420, and a slot 440 opened on the other side wall of the slide 420. What is not shown in the figure is that the outer wall of the first knob 130 is provided with a circle of dense teeth, and the inner wall of the slot 440 is provided with dense teeth that cooperate with the teeth. When the position of the two splints 200 needs to be adjusted, the slide 420 is pulled toward the fixed frame 410. The fixed frame 410 moves and squeezes the spring 430, and the first knob 130 is separated from the inside of the slot 440. The first knob 130 is rotated to adjust the position of the splint 200. After the adjustment is completed, the slide 420 is released, and the spring 430 rebounds and pushes the slide 420 toward the first knob 130 until the first knob 130 is embedded in the slot 440. The teeth on the outer wall of the first knob 130 and the teeth inside the slot 440 engage with each other to limit the rotation direction of the first knob 130.

[0032] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
