Abstract
The utility model provides a tool used for cable metal sheath opening expansion, which comprises: a wrench part having a structure suitable for hand holding; an engagement part connected with the wrench part having a gradually contracting flat shape to be clamped between a cable metal casing and a cable insulator. According to the utility model, because an engagement part connected the wrench part is applied, and it has a gradually contracting flat shape to be clamped between a cable metal casing and a cable insulator, the tool used for cable metal sheath expansion joint solves the problem of damage to the cable insulator when expanding opening of the metal sheath of high voltage cable by plier or spanner caused by contacting the cable insulator by the tool by overexerting, and achieves convenience for cable metal sheath opening expansion.
Description
Technical field
The utility model relates to a kind of instrument that is used for bloated mouthful of cable metal sheath.
Background technology
At present in the manufacturing process of high-voltage cable joint, generally the metallic sheath of high-tension cable to be expanded mouthful with pliers or spanner, the workmen need firmly clamp cable metal sheath with pliers or spanner, and then the mouth that expands.
In realizing the utility model process, the inventor finds that there are the following problems at least in the prior art: when using pliers or spanner that the metallic sheath of high-tension cable is expanded mouth, occur instrument touching cable insulation if overexert easily, cause cable insulation impaired.
The utility model content
The utility model aims to provide a kind of instrument that is used for bloated mouthful of cable metal sheath, can solve when using pliers or spanner that the metallic sheath of high-tension cable is expanded mouth, overexerting occurs instrument touching cable insulation easily, causes problems such as cable insulation is impaired.
In embodiment of the present utility model, a kind of instrument that is used for bloated mouthful of cable metal sheath is provided, it comprises: spanner portion has the structure that suitable staff is controlled; Bite, portion is connected with spanner, and it is gradually the flat of shrinking and is stuck between cable metal shell and the cable insulation being suitable for.
Preferably, bite is trapezoidal.
Preferably, the centre of bite has opening.
Preferably, spanner portion is elongated cylindrical.
Preferably, the length of spanner portion is greater than the length of described bite.
Preferably, spanner portion and described bite are integrated.
According to the instrument that is used for bloated mouthful of cable metal sheath of the present utility model, because adopted the bite that is connected with spanner portion, it is the flat of shrinking gradually and is suitable for being stuck in the mouth that expands between cable metal shell and the cable insulation, so overcome when using pliers or spanner that the metallic sheath of high-tension cable is expanded mouth, instrument touching cable insulation appears easily owing to overexert, cause the impaired problem of cable insulation, and then reached and be convenient to the effect that cable metal sheath expands mouthful.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the structure that is used for an embodiment of the instrument that cable metal sheath expands mouthful according to of the present utility model;
Fig. 2 has schematically shown the side-looking structure that is used for another embodiment of the instrument that cable metal sheath expands mouthful according to of the present utility model;
Fig. 3 has schematically shown among Fig. 2 the plan structure that is used for another embodiment of the instrument that cable metal sheath expands mouthful according to of the present utility model.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Fig. 1 has schematically shown according to the power structure that is used for an embodiment of the instrument that cable metal sheath expands mouthful of the present utility model.As shown in the figure, the instrument that is used for bloated mouthful of cable metal sheath of the present utility model comprises: spanner portion 1, and it has the structure that suitable staff is controlled, and can not cause the slippage of instrument when operating like this; Bite 2; be connected with spanner portion 1; its flat that is contraction gradually is to be suitable for being stuck in the mouth that expands between cable metal shell and the cable insulation; for example; as shown in Figure 2, the thickness h of bite 2 reduces gradually, and perhaps the thickness h of bite 2 and width all reduce gradually; when carrying out the bloated mouth of cable metal sheath, can protect cable insulation not to be damaged like this, and be convenient to operation.
As shown in Figure 3, preferably, bite 2 is trapezoidal.Help bite like this and insert between cable metal shell and the cable insulation, certainly bite also can be triangle etc. other be fit to be stuck in shape between cable metal shell and the cable insulation.
Preferably, the centre of bite 2 has opening 3.Opening 3 in the middle of the bite 2 can block the metal shell of cable preferably, thereby is convenient to bloated mouthful of operation of cable cover(ing).
Preferably, spanner portion 1 is elongated cylindrical.Control spanner portion when being convenient to operate so better, spanner portion also can be other shapes that are easy to control certainly.
Preferably, the length of spanner portion 1 is greater than the length of described bite.When expanding the mouth operation, can make the arm of force of the power that is applied to spanner portion bigger like this, thus more laborsaving.
Preferably, spanner portion 1 is integrated with described bite 2.Such sound construction, and be easy to make, spanner portion 1 also can link together by other modes and bite 2 certainly, for example welds together.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
According to the instrument that is used for bloated mouthful of cable metal sheath of the present utility model, because adopted the bite that is connected with spanner portion, its flat that is contraction gradually is to be suitable for being stuck in the mouth that expands between cable metal shell and the cable insulation, so overcome when using pliers or spanner that the metallic sheath of high-tension cable is expanded mouth, instrument touching cable insulation appears easily if overexert, cause the impaired problem of cable insulation, and then reached and be convenient to the cable metal sheath mouthful effect that expands.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
