Description

Technical Field

[0001] The utility model relates to the field of power detection, in particular to a power test clamp for power detection. Background Art

[0002] Electric power maintenance is mainly divided into the following maintenance parts: power generation part, power supply part, substation part and distribution part. Each part is managed by special personnel, who are mainly responsible for daily equipment installation and maintenance, troubleshooting, line inspection, etc., which are the maintenance of power grids and their ancillary equipment. The power test clamp for power maintenance is a clamp body used to test power lines during power maintenance. However, the existing test clamp has a relatively simple structure, and most of them adopt an integrated structure. This causes the test clamp to be partially damaged during use. The entire test clamp needs to be replaced, and the cost of use is relatively high. Secondly, the power test clamp used has a single clamping method and a fixed opening size. It cannot be reasonably adjusted according to the size of the conductive part of the equipment. If the clamp head clamps the conductive part of the equipment with a large opening, it is easy to disengage, which not only increases the difficulty of the staff's operation, but also poses a greater safety hazard. To solve the above problems, we propose an electric test clamp for power detection. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-5 As shown, an electric power test clamp for electric power detection comprises a test clamp body 1, the outer side of the test clamp body 1 is rotatably connected to a rotating shaft 5, the front end of the test clamp body 1 is fixedly connected to two groups of clamping mechanisms 6, the test clamp body 1 is respectively fixedly connected to protective covers 3 through the two groups of clamping mechanisms 6, the two groups of protective covers 3 are fixedly connected to the opposite sides thereof with test blades 4, the inner side of the test clamp body 1 is fixedly connected to a limiting mechanism 7, and the rear end of the test clamp body 1 is fixedly connected to a power cord 2.

[0020] In this embodiment, the clamping mechanism 6 includes an upper clamping plate 61 and a lower clamping plate 62. The lower end of the upper clamping plate 61 is fixedly connected with four groups of sliding columns 65. The upper end of the lower clamping plate 62 is provided with four groups of sliding grooves 66. The sliding columns 65 are adapted to the sliding grooves 66. The inner side of the upper clamping plate 61 is slidably connected with two groups of bolts 64. The inner side of the lower clamping plate 62 is provided with two groups of holes 67. The bolts 64 are adapted to the holes 67. The bolts 64 pass through the inner side of the holes 67 and are threadedly connected with nuts 68.

[0021] Specifically, through the cooperation of the slide column 65 and the slide groove 66, the upper clamping plate 61 and the lower clamping plate 62 can be conveniently fixed to each other at the bottom, and through the cooperation of the bolt 64 and the nut 68, the upper clamping plate 61 and the lower clamping plate 62 can be conveniently clamped to each other.

[0022] In this embodiment, two sets of limit rods 63 are fixedly connected to the lower end of the upper clamp 61, a limit hole 8 is opened at the upper end of the protective cover 3, the limit hole 8 is adapted to the limit rod 63, and a limit hole 8 is opened at the upper end of the test clamp body 1, the limit rod 63 is adapted to the limit hole 8.

[0023] Specifically, the connection between the protective cover 3 and the test clamp body 1 can be conveniently achieved through the cooperation between the limiting hole 8 and the limiting rod 63 .

[0024] In this embodiment, the limiting mechanism 7 includes a sleeve 72, which is fixedly connected to the test clamp body 1. A disc 74 is slidably connected to the inner side of the sleeve 72. A first spring 73 is fixedly connected to the lower end of the disc 74. The other end of the first spring 73 is fixedly connected to the test clamp body 1. A rack 71 is fixedly connected to the upper end of the disc 74. The upper end of the rack 71 is fixedly connected to the test clamp body 1.

[0025] Specifically, through the cooperation between the first spring 73 and the disc 74 , the rack 71 can conveniently drive the test clamp body 1 to clamp or open.

[0026] In this embodiment, one side of the limiting mechanism 7 is fixedly connected to a connecting box 77, the inner side of the connecting box 77 is slidably connected to a pull rod 78, the outer side of the pull rod 78 is sleeved with a second spring 76, one side of the second spring 76 is fixedly connected to the connecting box 77, the other side of the second spring 76 is fixedly connected to a limiting tooth 75, the limiting tooth 75 is fixedly connected to the pull rod 78, and the limiting tooth 75 is adapted to the rack 71.

[0027] Specifically, the rack 71 can be conveniently limited and fixed by the cooperation between the limiting teeth 75 and the second spring 76 .

[0029] Specifically, the test blade head 4 can be easily replaced through the cooperation between the connecting head 9 and the connecting groove 10 .

[0030] It should be noted that the utility model is an electric power test clamp for electric power detection. The user holds the test clamp body 1 with his hand, and then takes the test blade head 4 to the cable that needs to be tested. At this time, the test clamp body 1 is pressed hard, and the test blade head 4 will be clamped on the cable by force. Pressing the test clamp body 1 will drive the rack 71 to squeeze the disc 74 and the limiting teeth 75 to shrink into the inside of the sleeve 72. At this time, the rack 71 will also squeeze the limiting teeth 75. Through the cooperation of the second spring 76 and the connection box 77, the limiting teeth 75 can always limit and lock the rack 71 to prevent the test clamp body 1 from rebounding, and avoid the loosening of the test blade head 4 to cause inaccurate test data. When the test is completed, the pull rod 78 is pulled, and the pull rod 78 will drive the limiting teeth 75 to squeeze the second spring 76 from The limit on the rack 71 can be released by the elastic force of the first spring 73, and the disc 74 and the rack 71 can be pushed to move. The disc 74 is limited by the abutment against the limiting teeth 75, preventing the rack 71 from sliding out of the inner cavity of the sleeve 72, thereby releasing the clamping of the cable by the test cutter head 4. After a period of use, the test cutter head 4 is easily damaged and needs to be replaced. At this time, the nut 68 can be easily removed from the outside of the bolt 64 by rotating the nut 68, thereby releasing the mutual clamping between the lower clamp 62 and the upper clamp 61, and conveniently separating the lower clamp 62 and the upper clamp 61. The test cutter head 4 can be easily replaced by the cooperation between the connecting head 9 and the connecting groove 10, preventing the waste of resources caused by replacing the entire test clamp, which is more practical.
