Description
Technical field
The present invention relates in each field large and medium-sized equipment install with assembling process in be used for bolt the device that possesses safeguard function be installed, more specifically say, be particularly useful for the spanner of fastening outer-hexagonal bolt or outer-hexagonal nut use.
Background technology
Equipment install with assembling process in, majority is with the bolt connection, the large-scale bolt of using in the particularly large and medium-sized equipment fastening usually need be hit 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 impacting process, thereby produces following problem:
1, in the strike process, if be not to impact under the situation about being close together at two stress surfaces, can there be huge potential safety hazard in spanner because receive with the out-of-level power of spanner and being ejected by the reaction force of nut.
2, when impacting the bigger nut of appearance and size; If want to let two stress surfaces be close together, just need a personal hand or pin push-tight spanner (particularly when bolt is not the level installation), stress surface is close to; Another person hits spanner, has serious potential safety hazard.
3, the engineering time of installation of prolongation equipment or assembling, reduced efficiency of construction.
Summary of the invention
To equipment under the prior art install or assembling in need be with hitting the problem that is run in the spanner fastening bolt process, the present invention provides a kind of and enhances productivity, can effectively protect workmen and device security and device that can reusablely prevent to hit the spanner bounce-back.
In order to achieve the above object, the present invention has the strike spanner external member of anti-rebound function, comprises the spanner that is used for fastening bolt or nut, and bolt or nut that external member of the present invention is suitable for are mainly outer-hexagonal bolt or outer-hexagonal nut.External member of the present invention comprises that also a middle part is provided with the steel cable that the locating shim of hexagon ring, an end are fixed with ball, and a latch that offers bolt hole and circular hole.Hexagon ring on the locating shim is used to be socketed in outer-hexagonal bolt to be tightened or outer-hexagonal nut.In addition, cooperation is equipped with screw bolt and nut in the said bolt hole on the latch; And the rear end of said spanner handgrip part offers a through hole; Have a through wires hole on the outer rim lamellar body of said locating shim; The thread root of said bolt is provided with a radial hole.Operational phase, said steel cable penetrates said circular hole, penetrates said through hole again, then passes said through wires hole, passes said radial hole at last; Thereby said steel cable is provided with an end of ball and is stuck in said circular hole place, and the other end is fixed on the said bolt, and tension.
Under the optimal way, the position of the through wires hole on the said locating shim will exceed the maximum outside diameter of said spanner spanner; The diameter of said ball will be equal to or greater than the twice of said Circularhole diameter, is used to be stuck in said circular hole place; Said bolt hole and said circular hole are located on the center line of said latch.In addition, the verge of opening of said circular hole, said through hole, through wires hole and radial hole is 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 the strike process; Avoided ejecting the equipment or the personnel that cause and coming to harm, improved security and efficiency of construction when hitting nut because of hitting reaction force that spanner receives nut, and the save trouble and labor; Easy to use, improved efficiency of construction.

The specific embodiment
The present invention has the strike spanner external member of anti-rebound function, comprises that the rear end of handgrip part offers the spanner 12 of a through hole 14, comprises that also a middle part is provided with the locating shim 1 of hexagon ring 7.Have a through wires hole 6 on the outer rim lamellar body of locating shim 1 as shown in Figure 1.As shown in Figure 2, external member of the present invention comprises that also one one end is fixed with the steel cable 2 of ball 8; And as shown in Figure 3, a latch 3 that offers bolt hole 9 and circular hole 10.Shown in Figure 4 and 5, cooperate in the said bolt hole 9 to be equipped with bolt 4 and nut 5; The thread root of wherein said bolt 4 is provided with a radial hole 11.
Under the optimal way, the position of the through wires hole 6 on the locating shim 1 will exceed the maximum outside diameter of said spanner 12 spanners, thereby in case interferes.The diameter of the ball 8 of steel cable 2 ends will be equal to or greater than the twice of circular hole 10 diameters on the said latch 3.In addition, bolt hole 9 is located on the center line of said latch 3 with said circular hole 10.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.
Like Fig. 6 and user mode shown in Figure 7.First locating shim 1 is enclosed within needs on the fastening hex nut 13, will hit spanner 12 again and be enclosed within on the fastening hex nut 13 of needs.It should be noted that: the circular hole 14 to hit on the spanner 12 is center and through wires hole 6 lines of basic point to locating shim 1, and it is big that its angle will be tried one's best, and guarantees its more effective tension.Tension steel cable 2 is penetrated the circular hole 10 on the latch 3 earlier; Then penetrating strike spanner 12 impacts in the through hole 14 at place; Then will strain steel cable 2 again and penetrate in the through wires hole 6 on the locating shim 1, will strain at last in the radial hole 11 that steel cable 2 passes set bolt 4 upper ends.Set bolt 4 is inserted in the bolt hole 9 in the latch 3, drag and strain at tight steel cable 2, and nut 5 is tightened on the set bolt 4, length that so just can the fixed strain steel cable, two stress surfaces of assurance strike spanner and nut are close together.Improved security and efficiency of construction when hitting nut, and time saving and energy saving, easy to use, but reuse on the bolt of same size.
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 and can makes hexagon ring 7 that conventional hex nut penetrates and be used to strain the circular hole 6 that steel cable penetrates, and its appearance and size is wanted to make things convenient for penetrating of nut and tension steel cable 2; One end of tension steel cable 2 is provided with fixedly ball 8, and its appearance and size is greater than the internal diameter size of the circular hole 10 on the latch 3, to guarantee the steadiness after tension steel cable 2 is strained; One end of latch 3 is provided with the bolt hole 9 that is used to install and fix bolt; The other end is provided with and is used to strain the circular hole 10 that steel cable penetrates; Supporting with it set bolt 4 and nut 5; Guarantee bolt hole 9 and circular hole 10 on a center line, and the set bolt upper end is provided with and is used to strain the circular hole 11 that steel cable penetrates.Operational phase, said steel cable 2 penetrates said circular hole 10, penetrates said through hole 14 again, then passes said through wires hole 6, passes said radial hole 11 at last; Thereby said steel cable 2 is provided with an end of ball 8 and is stuck in said circular hole 10 places, and the other end is fixed on the said bolt 4, and said steel cable 2 is tightened up.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
