Description

Electrician's instrument convenient to twine insulating tape in narrow and small space

Technical Field

The utility model relates to the technical field of electrical tools, in particular to an electrical tool convenient for winding an insulating tape in a narrow space.

Background

The power line hidden in the wall hole (in the wall switch box of the factory building and the residence) at ordinary times is high in insulation failure frequency because of long service time, and the exposed length is limited by cutting through wiring for many times, so that the power line can be normally used only by being connected. Under general conditions, when the wire core is connected, the nipper pliers can extend into the wall hole to complete winding connection of the wire core, but when the insulating tape is wound, the nipper pliers cannot extend into the wall hole due to too small space. Because the power lines are parallel to the zero line and the live line and sometimes are accompanied with the ground line, the zero line and the live line are connected again at the same time at the parallel position of the same length by commonly connecting the power lines, if the winding of the outer insulating tape is disqualified because of the narrow space after the winding of the wire core is completed, the short circuit and the fire of the live line and the zero line are extremely easy to occur, and a plurality of short circuit faults of the power lines occur.

Through searching, the application number is as follows: 202221497899.9, the name of which is a published utility model patent for an insulating winding rod for uninterrupted operation of a developed distribution network. As can be seen from the disclosure, the insulating tape end is tightly clamped with the insulating wire by the insulating clamp, and the insulating tape winder can be assisted in controlling the travelling speed; the last insulating adhesive tape is tightly adhered with the insulating wire through the insulating lock rod, and the non-tight part adhered with the middle part of the insulating adhesive tape can be tightly pressed. However, the width of the winding shaft of the device is longer, so that when the power wire hidden in the wall hole is wound, the winding shaft cannot be fed into the wall hole, the operation of a user is inconvenient, the wall hole can be expanded by an electrician to operate in order to ensure that the insulating tape is wound up to be qualified, the wall surface is damaged, the damage is attractive, and the maintenance cost is increased.

Therefore, it is necessary to provide an electrical tool that facilitates winding an insulating tape in a narrow space to solve the above-mentioned technical problems.

The following describes in detail a new implementation of an electrical tool that facilitates winding insulating tape in a small space in conjunction with specific embodiments.

The utility model provides an electrician tool which is convenient for winding an insulating tape in a narrow space, comprising:

example 1

Referring to fig. 1, an electrical tool for conveniently winding an insulation tape in a narrow space comprises a handle 1 and a winding rod 2, wherein one end of the winding rod 2 is a winding end 201 for winding the insulation tape 7, and the other end of the winding rod 2 is installed inside the handle 1. When the adhesive tape is applied, a section of adhesive tape which is expected to be used is wound on the winding end 201, the end part of the outer end is turned over to expose a section of adhesive surface in the reverse winding direction, then the winding end 201 is extended into a narrow space of the wall hole 8, the outer end of the exposed adhesive surface is stuck and pressed on a region where the exposed core wire is wound, the winding end 201 is made to revolve around the core wire in the region, the winding rod 2 rotates while revolving, and the insulating adhesive tape 7 wound on the winding end 201 is unwound for winding wires. During winding, the winding end 201 can be moved inward or outward while winding so that the exposed core area is entirely covered. Therefore, under the condition that a hand cannot extend into the space of the wall hole 8, qualified winding operation can be performed on the exposed core wire area after winding, in order to facilitate that a rubber ring formed by the insulating tape which is wound on the winding end 201 in advance does not rotate relative to the winding rod 2 during operation, a notch 202 for inserting the initial end of the insulating tape 7 which is wound in advance into the winding is formed in the end part of the winding end 201, and the axial depth of the notch 202 is larger than the width of the insulating tape 7.

As one of the installation modes of the winding rod 2 and the grab handle 1, the winding rod 2 and the grab handle 1 are fixedly installed, and the connection mode is simple in structure and easy to develop and popularize.

Example two

Referring to fig. 2-4, the difference from the first embodiment is that the winding rod 2 and the handle 1 are elastically twisted and installed, and an elastic twisting assembly mechanism is provided, so that the winding rod 2 can twist at a limited angle relative to the handle 1 under elastic resistance, and the adhesive tape after the winding end 201 is unreeled is always in a tight state when the winding end 201 revolves around a core wire and needs to be changed, which is beneficial to tightly winding the insulating adhesive tape on a wire. Specifically:

the elastic torsion assembly mechanism comprises a torsion spring 3 and a sleeve 4, the front end of the grab handle 1 is provided with a sleeve mounting hole 101,

the sleeve 4 is fixed in the sleeve mounting hole 101, the rear end of the winding rod 2 is sleeved in the pipe hole 401 of the sleeve 4, the torsion spring 3 is sleeved at the rear end of the winding rod 2 and is positioned between the periphery of the winding rod 2 and the inner wall of the pipe hole 401, one end of the torsion spring 3 is limited on the winding rod 2, the other end of the torsion spring 3 is limited on the sleeve 4, and the rear section of the pipe hole 401 is an enlarged torsion spring mounting position 4011. When the winding end 201 receives a rotating force, the winding rod 2 is rotated by a certain angle under the elastic resistance of the torsion spring 3 until the torsion spring 3 reaches the torsion limit.

The sleeve 4 has an axial protrusion 402 axially provided on the outer periphery thereof to restrict rotation of the sleeve 4, and an axial groove 1011 for inserting the axial protrusion 402 is provided on the inner wall of the sleeve mounting hole 101, so that the sleeve 4 cannot rotate in the sleeve mounting hole.

Example III

Referring to fig. 5 to 7, it is different from the above embodiment in that the front end surface of the grip 1 around the outer circumference of the winding rod 2 is provided with a flashlight 5 for illuminating the operating environment forward to facilitate the winding operation. In general, even if a light is turned on indoors, there is a problem that the illumination is insufficient in a narrow wall hole 8, and an operator cannot use other illumination tools without his hands. A push button switch 6 for turning on the flashlight 5 is provided on the grip 1.

The flashlight 5 is powered by a battery, and a battery hole 102 for powering the flashlight 5 is arranged in the space at the rear section of the grab handle 1. The battery is preferably a universal battery of a general remote control, so that the battery of the remote control can be used temporarily under the condition that the tool does not have the battery or the battery fails.

The working principle of the electrician tool convenient for winding the insulating tape in a narrow space provided by the utility model is as follows:

a section of adhesive tape to be used is wound on the winding end 201, the end part of the outer end is turned over to expose a section of adhesive surface in the reverse winding direction, then the winding end 201 is extended into a narrow space of a wall hole 8, the outer end of the exposed adhesive surface is pressed on a region where the exposed core wire is wound, the winding end 201 is made to revolve around the core wire in the region, the winding rod 2 rotates while revolving, and the insulating adhesive tape 7 wound on the winding end 201 is unwound for winding wires. During winding, the winding end 201 can be moved inwards or outwards while winding, so that the exposed core wire area is completely covered, and in the case that the hand cannot extend into the wall hole 8, qualified winding operation can be performed on the exposed core wire area after winding.

The circuits and control involved in the present utility model are all of the prior art, and are not described in detail herein.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
