[0031] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application, obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0032] Please refer to Figures 1 to 3 The present application provides a technical scheme:

[0033] The utility model provides a lead protection device for electrical equipment, including the body 1, be equipped with the clamping component 30 on the left side of body 1, the clamping component 30 includes the shell 4 rotationally installed to the left side of body 1, the inside left side edge of shell 4 is fixedly installed with the inclined inclined plate 5 of position, the number of inclined plate 5 is six, the common fixed installation of one end between a plurality of inclined plate 5 is adjacent with the connecting ring 51, the inside rotation of shell 4 is installed with gear 7, the left side of gear 7 is rotationally installed with extrusion plate 9, extrusion plate 9 is between inclined plate 5 and body 1.

[0034] The circumferential surface of the shell 4 is provided with a through hole, the left side of the body 1 is rotationally installed with a pawl 2, the pawl 2 is engaged with the gear 7, the right end of the shell 4 is fixedly installed with a rotating ring 3, the rotating ring 3 is fixedly installed in the inside of the body 1, a hexagonal slide groove 8 is formed on the left side of the gear 7, slide groove holes 6 are formed on the left side to the right side of the inclined plate 5, slide columns 10 are fixedly installed on the left side of the extrusion plate 9, and the slide columns 10 are slidingly installed in the inside of the slide groove holes 6.

[0035] By adopting the above technical scheme, when in use, the operator needs to separate the pawl 2 and the gear 7, because the pawl 2 will make the gear 7 unable to rotate during use, thereby ensuring that the gear 7 will not cause the extrusion plate 9 to open and close automatically in the subsequent process. In addition, the right end of the shell 4 is fixedly installed with a rotating ring 3, and the rotating ring 3 is fixedly installed in the inside of the body 1, so that the shell 4 and the body 1 are not welded, thereby ensuring that the shell 4 can increase the hardness under the action of external force impact, and ensuring the stability of the shell 4.

[0036] At this time, the gear 7 is rotated, and the gear 7 will rotate synchronously with the hexagonal slide groove 8 during rotation. Because the gear 7 is inside the shell 4 and the right end is attached to the left side of the body 1, and the left side is attached to the inclined plate 5 inside the left side of the shell 4, the gear 7 can maintain good stability.

[0037] During the rotation of the gear 7, the slider 11 inside the hexagonal slide groove 8 slides. Because the slider 11 is fixedly installed on the right side of the extrusion plate 9, it will move synchronously with the connected extrusion plate 9. Because the slide columns 10 on the left side of the extrusion plate 9 are slidingly installed in the slide groove holes 6 formed in the inclined plate 5, the extrusion plate 9 will slide obliquely along the path of the slide groove hole 6 during sliding. In this way, the connecting ring 51 can be opened or closed to allow the wire harness 20 to pass through and fix the end of the wire harness 20, so that the connection end of the wire harness 20 will not loosen when it is pulled in the subsequent process. In this way, the safety of the lead connection is ensured.

[0038] Specifically, as Figures 2 to 5As shown, the right side straight corner of the extrusion plate 9 is fixedly installed with a sliding block 11, and the sliding block 11 is slidingly installed in the corresponding hexagonal sliding groove 8.

[0039] The left side of the shell 4 is fixedly installed with a connecting rod 12, and the inner side of the connecting rod 12 is provided with a reset assembly 40. The reset assembly 40 comprises an air column 13 fixedly installed on the inner side of the corresponding connecting rod 12. The inner side to the right end of the air column 13 is slidingly installed with a sliding rod 14. The left side of the air column 13 and the right end of the sliding rod 14 are fixedly installed with a circular ring 15. The inner side of the circular ring 15 is fixedly installed with a spring 16. The inner side of one end of a plurality of springs 16 is jointly installed with a cavity column 17. The circumferential surface to the inner side of the cavity column 17 is rotationally installed with a screw rod 19. The adjacent end of the adjacent screw rod 19 is rotationally installed with an arc-shaped plate 18 in the inner side of the cavity column 17. The wire harness 20 is inserted between the two arc-shaped plates 18.

[0040] By adopting the above technical scheme, the wire harness 20 passes through the inner side of the cavity column 17 one by one. At this time, the operating personnel manually rotates the screw rod 19 on the circumferential surface of the cavity column 17. The screw rod 19 pushes the adjacent arc-shaped plate 18 to gradually approach in the process of rotation. In this way, the arc-shaped plate 18 can fix the passing wire harness 20. It should be noted that a relatively long wire harness 20 is reserved between the right end of the cavity column 17 and the extrusion plate 9 to facilitate the subsequent pulling of the wire harness 20.

[0041] Then, when the wire harness 20 is inadvertently pulled, the air column 13 will be in a fixed state under the action of the connecting rod 12, and the wire harness 20 will gradually move away from the machine body 1 with the right end of the cavity column 17. In the process of moving away, the cavity column 17 pulls the spring 16, so that the spring 16 is pulled and the cavity column 17 in the inner side of the left and right end circular rings 15 is displaced.

[0042] In the process of pulling the right circular ring 15, the circular ring 15 pushes the sliding rod 14 to slide in the inner side of the air column 13. Because the inner side of the air column 13 contains an appropriate amount of gas, the sliding speed of the sliding rod 14 gradually decreases in the process of sliding, and the movement of the right circular ring 15 is slowed down. In this way, the pulling force of the spring 16 cannot be too large, avoiding the situation that the stress cannot be eliminated for a long time, so as to cause the spring 16 to fail. Under the action of the air column 13, the sliding rod 14 can be pushed to reset, so that the cavity column 17 can reset with the wire harness 20, avoiding the situation that the wire harness 20 and the machine body 1 are in a straight state, and avoiding the situation that there is no buffer between the wire harness 20 and the machine body 1 when the wire harness 20 is pulled.

[0043] Working principle: first, the wire harness 20 passes through the cavity column 17 one by one, and then rotates the screw rod 19 to fix it.

[0044] Then let the pawl 2 and gear 7 separate, rotate the gear 7, drive the extrusion plate 9 under the action of the hexagonal slide 8 to open operation, let the wire harness 20 pass through the connecting ring 51, gear 7 into the inside of the body 1.

[0045] Then reverse rotation gear 7 let the extrusion plate 9 in the closed rotation, fix the wire harness 20 and ensure that the gear 7 will not rotate under the action of the pawl 2. Then under the action of the air column 13, slide rod 14, spring 16 structure to ensure the displacement and reset of the wire harness 20.

[0046] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
