Description
Technical field
The large and medium-sized equipment in each field that the present invention relates to install and in assembling process for the device of bolt tool for mounting for safeguard function, more specifically, be particularly useful for the spanner of fastening outer-hexagonal bolt or the use of outer-hexagonal nut.
Background technology
Equipment is in installation and assembling process, and majority connects with bolt, the large-sized bolt particularly used in large and medium-sized equipment fastening, usually needs strike spanner.Because the inner hexagonal hole size of hitting spanner is greater than the hexagonal appearance and size of nut, so the stress surface of spanner and nut can not be close together all the time in shots, thus produces following problem:
1, in strike process, if impacted when two stress surfaces are not and are close together, spanner can be ejected by the reaction force of nut because being subject to the power out-of-level with spanner, there is huge potential safety hazard.
2, when the nut that impact appearance and size is larger, if want to allow two stress surfaces be close together, just need a personal hand or pin push-tight spanner (particularly when bolt is not level installation), stress surface is close to, another person hits spanner, there is serious potential safety hazard.
3, the engineering time of extension device installation or assembling, efficiency of construction is reduced.
Summary of the invention
Install for equipment under prior art or need with hitting the problem run in spanner fastening bolt process in assembling, the invention provides a kind ofly to enhance productivity, effectively can protect workmen and device security and reusablely can prevent from hitting the device that spanner rebounds.
In order to achieve the above object, the present invention has the strike wrench set of anti-rebound function, comprises the spanner for fastening bolt or nut, and the bolt that external member of the present invention is suitable for or nut are mainly outer-hexagonal bolt or outer-hexagonal nut.External member of the present invention also comprises the steel cable that a middle part is provided with the locating shim of hexagon ring, an one end is fixed with ball, and a latch offering bolt hole and circular hole.Hexagon ring on locating shim is for being socketed in outer-hexagonal bolt to be tightened or outer-hexagonal nut.In addition, coordinate in the described bolt hole on latch and be equipped with screw bolt and nut; And the rear end of described spanner handgrip part offers a through hole; The outer rim lamellar body of described locating shim has a through wires hole; The thread root of described bolt is provided with a radial hole.Operational phase, described steel cable penetrates described circular hole, then penetrates described through hole, then through described through wires hole, eventually passes through described radial hole; Thus one end that described steel cable arranges ball is stuck in described circular hole place, the other end is fixed on described bolt, and strains.
Under preferred embodiment, the position of the through wires hole on described locating shim will exceed the maximum outside diameter of described spanner spanner; The diameter of described ball will be equal to or greater than the twice of described Circularhole diameter, for being stuck in described circular hole place; Described bolt hole and described circular hole are located on the center line of described latch.In addition, the verge of opening of described circular hole, described through hole, through wires hole and radial hole all with level and smooth arc angling transition, in case steel cable is under tension, by the edge damage in hole.
The invention has the advantages that, anti-rebounding device of the present invention can make the stress surface of nut and spanner be close together all the time in strike process, avoid equipment that the reaction force and ejecting that is subject to nut because hitting spanner causes or personnel come to harm, improve security when hitting nut and efficiency of construction, and save trouble and labor, easy to use, improve efficiency of construction.

Detailed description of the invention
The present invention has the strike wrench set of anti-rebound function, and the spanner 12 of a through hole 14 is offered in the rear end comprising handgrip part, also comprises the locating shim 1 that a middle part is provided with hexagon ring 7.The outer rim lamellar body of locating shim 1 as shown in Figure 1 has a through wires hole 6.As shown in Figure 2, external member of the present invention also comprises the steel cable 2 that an one end is fixed with ball 8; And as shown in Figure 3, a latch 3 offering bolt hole 9 and circular hole 10.As shown in Figures 4 and 5, in described bolt hole 9, cooperation is equipped with bolt 4 and nut 5; The thread root of wherein said bolt 4 is provided with a radial hole 11.
Under preferred embodiment, the position of the through wires hole 6 on locating shim 1 will exceed the maximum outside diameter of described spanner 12 spanner, thus in case interferes.The diameter of the ball 8 of steel cable 2 end will be equal to or greater than the twice of circular hole 10 diameter on described latch 3.In addition, bolt hole 9 and described circular hole 10 are located on the center line of described latch 3.And the verge of opening of above-mentioned circular hole 10, through hole 14, through wires hole 6 and radial hole 11 is all with level and smooth arc angling transition.
Using state as shown in Figure 6 and Figure 7.First locating shim 1 is enclosed within and needs on fastening hex nut 13, then be enclosed within hitting spanner 12 on the fastening hex nut 13 of needs.It is to be noted that be basic point to the center of locating shim 1 and through wires hole 6 line with the circular hole 14 hit on spanner 12, it is large that its angle will be tried one's best, and ensures its more effective tension.Tension steel cable 2 is first penetrated the circular hole 10 on latch 3, then penetrate in the through hole 14 hitting spanner 12 impact place, then again tension steel cable 2 is penetrated in the through wires hole 6 on locating shim 1, finally tension steel cable 2 is passed in the radial hole 11 of set bolt 4 upper end.Set bolt 4 is inserted in the bolt hole 9 in latch 3, drag and strain at tight steel cable 2, and nut 5 is tightened on set bolt 4, so just can the length of fixed strain steel cable, ensure that two stress surfaces hitting spanner and nut are close together.Improve security when hitting nut and efficiency of construction, and time saving and energy saving, easy to use, can the bolt of same size be reused.
Strike spanner of the present invention is provided with anti-rebounding device, comprise locating shim 1, tension steel cable 2, latch 3, locating shim 1 is provided with the hexagon ring 7 that conventional hex nut can be made to penetrate and for straining the circular hole 6 that steel cable penetrates, its appearance and size wants to facilitate penetrating of nut and tension steel cable 2; One end of tension steel cable 2 is provided with fixing ball 8, and its appearance and size is greater than the internal diameter size of the circular hole 10 on latch 3, to ensure the steadiness after straining steel cable 2 tension; One end of latch 3 is provided with the bolt hole 9 for installing set bolt, the other end is provided with the circular hole 10 penetrated for straining steel cable, set bolt 4 supporting with it and nut 5, ensure that bolt hole 9 and circular hole 10 are on a center line, and set bolt upper end is provided with the circular hole 11 penetrated for straining steel cable.Operational phase, described steel cable 2 penetrates described circular hole 10, then penetrates described through hole 14, then through described through wires hole 6, eventually passes through described radial hole 11; Thus one end that described steel cable 2 arranges ball 8 is stuck in described circular hole 10 place, the other end is fixed on described bolt 4, and described steel cable 2 is tightened up.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
