Description

Technical Field

[0001] The utility model belongs to the technical field of electric power construction, and in particular relates to an insulation wire stripper for high and low voltage distribution network construction. Background Art

[0002] High and low voltage distribution networks are crucial components of the power system, distributing electricity from power plants or substations to consumers. High-voltage distribution networks typically connect power plants and substations, efficiently delivering electricity to key substation facilities. Low-voltage distribution networks typically operate at voltage levels below 1 kV, such as 220 V and 380 V. This portion of the grid ensures that electricity reaches consumers safely and meets daily electricity needs.

[0003] During routine maintenance, electricians are often required to strip the insulation covering cables for inspection and testing. When repairing or replacing cables, the insulation needs to be stripped to access the cable connections, inspect the cable's condition, or make necessary repairs. When connecting the cable's metal shield or ground wire to the grounding system, the insulation must be stripped to ensure proper grounding. The design of insulation strippers makes wire stripping quicker and easier, helping construction workers quickly complete cable processing, improving overall construction efficiency and saving time and costs. However, existing designs are relatively long and take up a lot of space, making them difficult to carry and place. Using larger equipment in small or confined spaces can be inconvenient, impacting construction progress and quality.

[0004] In summary, existing wire strippers have the problem of being large in size and inconvenient to carry. Utility Model Content

[0005] In view of this, the utility model provides an insulated wire stripper for high and low voltage distribution network construction, which can solve the problem that the existing wire strippers are large in size and inconvenient to carry.

[0006] The utility model is achieved in this way:

[0007] The utility model provides an insulated wire stripping pliers for high and low voltage distribution network construction, which includes a metal pliers body, teeth, and a pin shaft. The metal pliers body is rotatably connected to a first handle through the pin shaft. The metal pliers body is provided with a plurality of teeth, and the teeth are used to strip the insulation layer on the distribution network line. A second handle is provided below the first handle, and the second handle is sleeved on the outside of the first handle. The bottom of the first handle is fixedly connected to a fastener, and the second handle is slidably connected to the first handle through the fastener. An insulating sleeve is provided on the outside of the second handle.

[0008] The utility model provides an insulated wire stripper for high- and low-voltage distribution network construction, providing the following technical advantages: By providing a metal pliers body and teeth, the pliers can quickly and efficiently strip the insulation layer of a cable, saving time, improving work efficiency, effectively avoiding damage to the cable's internal conductors, and ensuring cable performance and safety. The teeth increase friction with the cable surface, ensuring that the cable does not slip during stripping, providing better control. By providing a first handle and a second handle, the overall size of the wire stripper can be reduced, making it easier to store in a toolbox or workbench, saving storage space. The slidable design of the first handle makes the tool more convenient to carry. Sliding the first handle inward from the second handle reduces the overall size, minimizing exposure of the metal pliers body, thereby reducing potential damage to the user and surrounding objects. The slidable handle design makes the tool easier to operate and increases flexibility. The insulating sleeve prevents electric shock, ensuring that the operator does not accidentally contact live parts during stripping. The insulating sleeve provides a better anti-slip effect, improving the stability and control of the tool during use.

[0009] On the basis of the above technical solution, the utility model of a high and low voltage distribution network construction insulation stripper can also be improved as follows:

[0010] Wherein, the first handle includes a connecting head and a sliding part, the connecting head is rotationally connected to the metal pliers body through the pin shaft, the connecting head is fixedly connected to the sliding part, and the bottom of the sliding part is fixedly connected with a fastener.

[0011] Furthermore, the second handle includes an outer handle rod, a sliding groove and a fastening cavity. The outer handle rod is sleeved on the outside of the sliding part. The sliding part is slidably connected to the outer handle rod. The sliding groove and the fastening cavity are provided on the inner wall of the outer handle rod.

[0012] Furthermore, the slide groove and the fastening cavity are perpendicular to each other, the slide groove is a linear structure, and the fastening cavity is an annular structure, and both the slide groove and the fastening cavity are adapted to the fastener.

[0013] Furthermore, the fastening cavity is located at the upper end of the inner wall of the outer handle rod, and the sliding groove passes through the fastening cavity.

[0014] Furthermore, an elastic extrusion piece is fixedly connected to the interior of the fastening cavity, and the thickness of the elastic extrusion piece gradually becomes thicker as it moves away from the sliding groove, and the elasticity of the elastic extrusion piece gradually increases as it moves away from the sliding groove.

[0015] Furthermore, the surface of the outer handle is provided with a magnetic coating, and the magnetic coating is used to absorb small metal parts.

[0016] Furthermore, the outer sleeve of the outer handle rod is provided with an insulating sleeve, and the insulating sleeve is made of synthetic rubber.

[0017] Furthermore, the insulating sleeve is provided with a plurality of grooves, and the grooves fit the shape of fingers.

[0018] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing the groove, the handle is more in line with the natural gripping posture of the hand during use, thereby increasing comfort.

[0019] Furthermore, the fastener is made of elastic rubber.

[0020] Compared to existing technologies, the present invention provides an insulated wire stripper for high- and low-voltage distribution network construction. The advantages of the present invention include: By providing a metal pliers body and teeth, the stripper can quickly and efficiently strip the insulation layer of a cable, saving time, improving work efficiency, effectively avoiding damage to the cable's internal conductors, and ensuring cable performance and safety.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] like Figure 1-3 As shown, an embodiment of an insulated wire stripping pliers for high and low voltage distribution network construction provided by the utility model is shown. In this embodiment, the pliers include a metal pliers body 10, teeth 11, and a pin 12. The metal pliers body 10 is rotatably connected to a first handle 13 via the pin 12. The metal pliers body 10 is provided with a plurality of teeth 11, and the teeth 11 are used to strip the insulation layer on the distribution network wire. A second handle 14 is provided below the first handle 13, and the second handle 14 is sleeved on the outside of the first handle 13.

An insulating sleeve 15 is provided on the outside of the second handle 14.

[0029] During use, the sliding portion 132 is pulled to slide inside the outer handle 141, and the fastener 18 moves upward along the slide groove 142 as the sliding portion 132 slides upward until the fastener 18 moves to the fastening cavity 143. The sliding portion 132 and the slide groove 142 are slid relative to each other. At this time, the fastener 18 moves in the fastening cavity 143. Since the thickness and elasticity of the elastic extrusion member 19 away from the slide groove 142 gradually increase, the fastener 18 is gradually clamped by the elastic extrusion member 19 in the fastening cavity 143. At this time, the sliding portion 132 and the outer handle 141 no longer move relative to each other, and the finger is stuck in the groove 16. The second handle 14 of Anton performs the insulation wire stripping operation. When some delicate small parts need to be used and accidentally fall off during operation, the magnetic coating 17 can adsorb them to the outer surface of the insulating sleeve 15 to prevent the small parts from falling directly, thereby increasing safety. After use, the sliding part 132 is rotated back so that the fastener 18 slides out of the fastening cavity 143 and returns to the sliding groove 142. At this time, the sliding part 132 is slid downward to the inside of the outer handle rod 141 to reduce the size of the entire wire stripper, and the small-sized wire stripper can be easily stored.

[0030] In the above technical solution, the first handle 13 includes a connecting head 131 and a sliding part 132. The connecting head 131 is rotationally connected to the metal pliers body 10 through a pin shaft 12. The connecting head 131 is fixedly connected to the sliding part 132. The bottom of the sliding part 132 is fixedly connected with a fastener 18.

[0031] Furthermore, in the above technical solution, the second handle 14 includes an outer handle rod 141, a sliding groove 142 and a fastening cavity 143. The outer handle rod 141 is sleeved on the outside of the sliding part 132. The sliding part 132 is slidingly connected to the outer handle rod 141. The sliding groove 142 and the fastening cavity 143 are provided on the inner wall of the outer handle rod 141.

[0032] Furthermore, in the above technical solution, the slide groove 142 and the fastening cavity 143 are perpendicular to each other, the slide groove 142 is a linear structure, and the fastening cavity 143 is an annular structure. Both the slide groove 142 and the fastening cavity 143 are adapted to the fastener 18 .

[0033] Furthermore, in the above technical solution, the fastening cavity 143 is located at the upper end of the inner wall of the outer handle rod 141 , and the sliding groove 142 passes through the fastening cavity 143 .

[0034] Furthermore, in the above technical solution, an elastic extrusion member 19 is fixedly connected to the interior of the fastening cavity 143 , and the thickness of the elastic extrusion member 19 gradually becomes thicker as it moves away from the slide groove 142 , and the elasticity of the elastic extrusion member 19 gradually increases as it moves away from the slide groove 142 .

[0035] Furthermore, in the above technical solution, a magnetic coating 17 is provided on the surface of the outer handle rod 141 , and the magnetic coating 17 is used to absorb small metal parts.

[0036] Furthermore, in the above technical solution, an insulating sleeve 15 is provided on the outside of the outer handle rod 141, and the insulating sleeve 15 is made of synthetic rubber.

[0037] Furthermore, in the above technical solution, a plurality of grooves 16 are provided on the insulating sleeve 15 , and the grooves 16 fit the shape of the fingers.

[0038] Furthermore, in the above technical solution, the fastener 18 is made of elastic rubber.

[0039] Specifically, the principle of the present invention is as follows: when in use, the sliding portion 132 is pulled to slide inside the outer handle 141, and the fastener 18 moves upward along the slide groove 142 as the sliding portion 132 slides upward until the fastener 18 moves to the fastening cavity 143, and the sliding portion 132 and the slide groove 142 slide relative to each other. At this time, the fastener 18 moves in the fastening cavity 143. Since the thickness and elasticity of the elastic extrusion member 19 away from the slide groove 142 gradually increase, the fastener 18 is gradually clamped by the elastic extrusion member 19 in the fastening cavity 143. At this time, the sliding portion 132 and the outer handle 141 no longer move relative to each other, and the finger is stuck in the groove 16. The second handle 14 of Anton performs the insulation wire stripping operation. When some delicate small parts need to be used during operation and accidentally fall off, the magnetic coating 17 can adsorb them to the outer surface of the insulating sleeve 15 to prevent the small parts from falling directly, thereby increasing safety. After use, the sliding part 132 is rotated back so that the fastener 18 slides out of the fastening cavity 143 and returns to the sliding groove 142. At this time, the sliding part 132 is slid downward to the inside of the outer handle rod 141 to reduce the size of the entire wire stripper, and the small-sized wire stripper can be easily stored.
