Abstract
The utility model relates to a socket wrench with adjustable torque. The utility model comprises a handle, a housing, a ratchet wheel, a ratchet shaft, and a sleeve barrel, wherein, A torque adjusting mechanism which is composed of a butting post with steps, a pressing spring, an adjusting spring, and a screwing spring is arranged behind the ratchet shaft in the housing; a front end of the butting post, which penetrates through a butting post hole on the housing, glidingly contacts the ratchet shaft; the pressing spring is sheathed on the butting post, and the adjusting nut, the screwing nut, and an inner wall of the housing on a back end of the butting post are in screw connection; the housing is provided with a ratchet shaft hole whose cross section forms a long circular shape. The utility model can apply torque which is arranged in advance to a fastener, can guarantee the intensity of a member, and can protect the fastener against being damaged.
Description
The utility model relates to a kind of fastening hand tools that is used for, particularly a kind of box spanner.
A kind of quick box spanner is arranged at present, it is formed and mainly comprises handle, housing, ratchet, sour jujube axle, sleeve, ratchet both sides square toes are connected with two sleeves, a pair of not in the same way ratchet is arranged on the sour jujube axle, sour jujube axle rear side has the locating slot on two band inclined-planes, promote the sour jujube axle, make the location ball of sour jujube axle retainer spring front end fall into different locating slots, just can make the engagement of ratchets different on the sour jujube axle and hook tooth.During work, a side jacket casing is being desired on the fastening nut, only needed the waggle handle, the ratchet on the sour jujube axle is stirred hook tooth, drives sleeve nut is applied moment of torsion, with nut screwing clamping.The effect of two ratchets on the sour jujube axle is to change the direction that sleeve applies moment of torsion.The shortcoming of this quick box spanner is the moment of torsion that is applied to be limited and regulate.Moment of torsion is not enough, and securing member is easily loosening, and moment of torsion is excessive, and securing member is damaged.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned box spanner, provides a kind of moment of torsion adjustable box spanner.
The purpose of this utility model realizes by following technical solution: a kind of moment of torsion adjustable sleeve spanner, its composition comprises handle, housing, ratchet, sour jujube axle and retainer spring thereof, the location ball, sleeve, it is characterized in that sour jujube axle rear side has by fore-set with the level in housing, holddown spring, adjusting nut, the torque adjustment mechanism that fastening screw nut is formed, the fore-set front end passes fore-set hole and the sliding-contact of sour jujube axle on the housing, holddown spring is enclosed within on the fore-set, adjusting nut and fastening screw nut are threaded with fore-set rear end inner walls, and having the cross section on the housing is oblong sour jujube axis hole.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A schematic diagram of Fig. 1.
As depicted in figs. 1 and 2, the composition of the utility model moment of torsion adjustable sleeve spanner comprises handle 8, housing 11, ratchet 1, sour jujube axle 12, sour jujube axle retainer spring 9, location ball 10, sleeve 13,14, have on the sour jujube axle 12 a pair of not in the same way, can with the ratchet 2 of hook tooth engagement, sour jujube axle 12 rear sides have by fore-set 4 with the level in housing 11, holddown spring 5, adjusting nut 6, the torque adjustment mechanism that fastening screw nut 7 is formed, fore-set 4 front ends pass the fore- set hole 3 and 12 sliding-contacts of sour jujube axle on the housing, holddown spring 5 is enclosed within on the fore-set 4, adjusting nut 6 is connected with fore-set rear end housing 11 inner threads with fastening screw nut 7, and having the cross section on the housing is oblong sour jujube axis hole 15.During use; earlier give holddown spring 5 certain pre-pressing force by adjusting nut 6; just define moment of torsion to box spanner; twist moment when reaching predetermined moment of torsion when applying with this box spanner; the ratchet 2 that tooth on the ratchet 1 will promote on the sour jujube axle 12 moves backward; the sour jujube axle will overcome the thrust of the spring of its rear side torque adjustment mechanism this moment; move to Long Circle sour jujube axis hole 15 rear sides; throw off because of the changing of the relative positions up to two engaging tooths; moment of torsion that handle adds will reduce to zero from limit value this moment, reach the effect that limits moment of torsion, protection securing member from face.
Regulate the pre-pressing force of holddown spring 5, also just regulated the qualification moment of torsion of box spanner, it both can guarantee to reach the required moment of torsion of fastening nut, guarantee to be no more than this torque value again, thereby guarantee robustness and rigidity after the member assembling, do not make screw thread impaired, prolonged the service life of fastener constructions because of excessive moment of torsion.
Among the embodiment, sour jujube axle rear side has two torque adjustment mechanisms that structure is identical in the utility model housing, and the sleeves different for specification use.Holddown spring adopts disk spring, to obtain the bigger thrust that presets.In order to make the utility model can pass through long screw rod and fastening nut, further feature is that ratchet 1 is hollow ratchet.
Claims (3)
1, a kind of moment of torsion adjustable sleeve spanner, its composition comprises handle, housing, ratchet, sour jujube axle and retainer spring thereof, location ball, sleeve, it is characterized in that sour jujube axle rear side has the torque adjustment mechanism that is made up of fore-set with the level, holddown spring, adjusting nut, fastening screw nut in housing, the fore-set front end passes fore-set hole and the sliding-contact of sour jujube axle on the housing, holddown spring is enclosed within on the fore-set, adjusting nut and fastening screw nut are threaded with fore-set rear end inner walls, and having the cross section on the housing is oblong sour jujube axis hole.
2, moment of torsion adjustable sleeve spanner according to claim 1 is characterized in that sour jujube axle rear side has two torque adjustment mechanisms that structure is identical in the housing.
