DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses an electrical detector for maintaining electrical equipment.

[0026] The utility model provides Figure 1-3 An electrical detector for electrical equipment maintenance shown in the figure comprises a detector body 1 and a protective cover 2 slidably sleeved on the outside of the detector body 1, a joint 3 is connected to the top of the detector body 1, an elastic opening and closing mechanism is provided between the protective cover 2 and the detector body 1, and the elastic opening and closing mechanism comprises a fixed block 9, a sliding hole is provided at the lower end of the outer side of the protective cover 2, the fixed block 9 is fixedly connected to the outer side of the detector body 1 and slidably arranged in the sliding hole, a spring 10 is fixedly arranged between the fixed block 9 and the top of the inner wall of the sliding hole, and a limit plate 21 is fixedly arranged at the lower ends of the front and rear sides of the detector body 1;

[0027] A sleeve 4 is fixedly provided on the back side of the protective cover 2, and an air inlet pipe 5 and an air outlet pipe 6 are connected to both ends of the top of the sleeve 4. The pipe mouth of the air outlet pipe 6 is fixedly penetrated through the side of the joint 3 and is connected to the joint 3. A piston 7 is slidably penetrated through the inner wall of the sleeve 4, and a piston rod 8 is fixedly provided at the bottom of the piston 7. The pipe walls of the air inlet pipe 5 and the air outlet pipe 6 are fixedly sleeved with a gas one-way valve 20.

[0028] When the detector body 1 is placed normally, the protective cover 2 wraps and protects the detector body 1. At this time, the display area on the surface of the detector body 1 is covered. When equipment maintenance is required, the protective cover 2 can be pressed through the elastic cooperation between the fixing block 9 and the spring 10, so that the protective cover 2 moves downward and the display position of the detector body 1 is exposed. During this process, the piston rod 9 drives the piston 7 to move back and forth inside the sleeve 4. When the piston 7 moves downward, the external air is sucked into the sleeve 4 through the air inlet pipe 5. When the piston 7 moves upward, the piston 7 blows the internal air into the connector 3 through the air outlet pipe 5, and blows out the dust inside the connector 3, so as to avoid the occurrence of unstable connection between the external cable and the connector 3 during the detection process, and ensure the use effect of the detector.

[0029] In order to enable the piston rod 8 to move longitudinally, Figure 2-3 As shown, the reciprocating mechanism includes a fixed plate 11, which is fixedly provided with the rear side of the inner wall of the protective cover 2, a reciprocating screw rod 12 is rotatably penetrated inside the fixed plate 11, a moving block 13 is threadedly sleeved on the rod wall of the reciprocating screw rod 12, a connecting plate 14 is fixedly provided on the side wall of the moving block 13, the connecting plate 14 passes through the protective cover 2 and is fixedly connected to the bottom of the piston rod 8, and a limiting hole is opened on the back side of the protective cover 2 to cooperate with the sliding of the connecting plate 14.

[0030] When the protective cover 2 moves downward, the reciprocating screw 12 is driven to push the moving block 13 back and forth. During this process, the moving block 13 can only move longitudinally through the sliding cooperation of the connecting plate 14 and the limiting hole. At this time, under the connection between the connecting plate 14 and the piston rod 8, the piston rod 8 can drive the piston 7 to move back and forth in the sleeve 4, so that the sleeve 4 can frequently inhale and blow out the gas.

[0031] In order to ensure that the reciprocating screw rod 12 can be stably driven when the protective cover 2 moves downward, Figure 2-3 As shown, a rack 15 is fixedly provided on the lower end of the back side of the detector body 1, a cross bar 16 is rotatably provided on the inner lower end of the protective cover 2, a circular gear 17 is fixedly sleeved on the rod wall of the cross bar 16, and the circular gear 17 is fixedly sleeved with the cross bar 16, and a first bevel gear 18 and a second bevel gear 19 are fixedly provided on the reciprocating screw 12 and the cross bar 16 at one end close to each other, and the first bevel gear 18 and the second bevel gear 19 are meshingly arranged.

[0032] When the protective cover 2 moves downward, since the position of the rack 15 is fixed, when the circular gear 17 is engaged with the rack 15, the circular gear 17 is pushed to drive the cross bar 16 to rotate. At this time, under the engagement of the first bevel gear 18 and the second bevel gear 19, the reciprocating screw 12 can be stably driven.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
