Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the puncture electricity-testing grounding hanging ring comprises a rectangular ring body 1, an insulating sleeve 2 wraps the outer side of the ring body 1, and a puncture wire clamp 3 is fixedly mounted at the upper end of the ring body 1. The outer side of the puncture wire clamp 3 is sleeved with an insulating sheath 15, and the insulating sheath 15 is detachably connected to the puncture wire clamp 3.

As shown in fig. 1 and 2, the left and right sides of the insulating sleeve 2 are symmetrically sleeved with sleeves 4, and the sleeves 4 are slidably arranged on the insulating sleeve 2 along the vertical direction. All be provided with pendant 5 that 3 directions of upwards facing puncture fastener extend on the lateral wall that two sleeves 4 deviate from each other, and two pendants 5 slope to the direction of keeping away from each other gradually.

As shown in fig. 1 and 2, the hanging member 5 includes a circular tube 7 rotatably connected to the casing 4 at a lower end thereof, and an extension arm 8 screwed into the circular tube 7. The lower end of the circular tube 7 can rotate around one side of the sleeve 4 in the circumferential direction, the upper end of the extension arm 8 penetrates out of the upper end of the circular tube 7, and the hook 6 which is bent downwards is formed at the top of the extension arm 8. The extension arm 8 is attached with a scale 13 along the length direction. The top of the extension arm 8 is also hinged with a hook 9 positioned below the hook 6, and the hook 9 can rotate around the hinged position along the vertical direction. The clamping hook 9 and the hook 6 are oppositely arranged, a through hole 10 for the cable to pass through is formed between the clamping hook and the hook, and a rubber cushion 12 which is circumferentially surrounded is fixedly adhered to the inner side wall of the through hole 10.

As shown in fig. 1 and 3, a spring 11 is fixedly installed in the extension arm 8, and an upper end of the spring 11 faces a lower side wall of the hook 9, and the other end of the spring 11 abuts against the lower side wall of the hook 9. The upper end of the clamping hook 9 is tightly propped against the hook 6 under the action of the elastic force of the spring 11. The outer side wall of the clamping hook 9 is fixedly provided with a pull ring 14 far away from the extension arm 8, and the pull ring 14 is positioned below the hook 6. The two extension arms 8 are respectively located at two sides of the insulating sheath 15, and when the ring body 1 is hung on the cable through the extension arms 8, the left end and the right end of the insulating sheath 15 are in contact with the side walls of the opposite extension arms 8.

The specific effects of the embodiment are as follows:

when installing ring body 1, because extension arm 8 upper end is formed with couple 6, hang ring body 1 on the cable through couple 6 earlier, when the cable passes in following perforation 10, trip 9 can firmly compress tightly the cable in perforation 10 under the effect of spring 11 to just can realize the preliminary fixed to ring body 1. When the staff is pressing from both sides the puncture fastener 3 through the upper end with ring body 1 and pressing from both sides tightly on the cable, owing to carried out preliminary fixed to ring body 1, the staff just need not to hold ring body 1 with the hand again when the installation, has made things convenient for the staff to vacate the hand and has carried out the cable and right straight fixedly. Through rotating extension arm 8 and can realizing adjusting extension arm 8's extension length, through the length adjustment with extension arm 8 to suitable position, enable the cable and stabilize spacing in puncture fastener 3, avoid the cable to break away from in puncture fastener 3. And hang ring body 1 on the cable also can avoid making the condition that ring body 1 falls from the high altitude because of staff's hand slips.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
