Abstract
A quick action spanner bearing big torque force is used for tightening or loosing a screw and a nut. The quick action spanner is in a housing. A driving element engages with a spanner main body by the triangle tooth of a bevel gear and the loading force of a spring to enlarge contact area and improve the ability of a bearing force moment. The quick action spanner bearing big torque force solves the defect that other quick action spanners doesn't bear big torque force in prior art.
Description
Affiliated technical field:
The utility model relates to a kind of manual speeder wrench, especially can bear the speeder wrench of big torsion.
Background technology:
Present known ratchet-type speeder wrench because these parts such as ratchet, ratchet, trunnion, tooth can not bear big torsion, thereby causes this spanner not satisfy, and needs hundreds of, several thousand even the construction needs of the king-bolt of a few Wan Niumi torsion.(for example: the tire bolt of cargo vehicle, the flange plate bolt of petroleum chemical enterprise.) these bolts all need very large torsion, if there is not speeder wrench to construct, will waste the quality time of dozens of minutes even several hrs.This shortcoming and the modern production of seizing every minute and second, life are extremely unbecoming, save to be solved.
Summary of the invention:
The ratchet-type speeder wrench can not bear this shortcoming of big torsion in the prior art in order to overcome, and the utility model provides a kind of big torsion speeder wrench, and screw, nut can be tightened or unclamp to this spanner not only fast.Especially can bear the huge torsion that surpasses existing rapid spanner tens, hundred times.Bear this technical problem of big torsion thereby solved.
The technical scheme that its technical problem that solves the utility model adopts is: in the shell that punching press is made, with oval section volute spring with the side of making, two ends tenon, the centre is the driving member of bevel gear, is loaded into an end and makes on the wrench body of bevel gear, other end band handle.(the punching press shell is integral with being threaded with wrench body).The intermeshing tooth of bevel gear on bevel gear on will the driving member vertical with wrench body and the wrench body, making cross section is the lance tooth that acute angle makes progress.The sliding friction face is a slope shape like this, and the field of conjugate action is intilted tiltedly to shape.Thereby make wrench body for driving member, can only dally to a direction, and oppositely must drive driving member rotation along the main shaft of driving member, make torque transmitting that driving member uploads wrench body to extension bar or sleeve on bolt, nut.Thereby make bolt or nut screwing clamping.If want to unclamp bolt, nut, then spanner is exchanged up and down, make another side's feather joint on extension bar or sleeve.At this moment, spanner can only oppositely then can only dally to another direction transmission torque.
The beneficial effects of the utility model are: owing to adopt technique scheme, the utility model can positive and negative both direction, tightens fast or unclamps bolt, nut; Again since between wrench body and driving member area of contact than other ratchet-type speeder wrench ratchet, ratchet contact area increased tens, hundred times, thereby make the utility model can bear huge torsion, solved the technical problem that can not bear too big torsion that in prior art, exists.And the few structure of parts is very simple.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1, be the utility model assembly structure figure.
Fig. 2, be cut-away view of the present utility model.
Fig. 3, be the utility model and extension bar and sleeve, bolt, nut connection layout.
Among the figure, 1, driving member spindle hole 2, punching press shell 3, volute spring 4, driving member side's tenon 5, spacing steel ball 6, driving member main shaft 7, driving member bevel gear 8, screw thread 9, wrench body bevel gear 10, handle 11, wrench body 12, spring 13, driving member umbrella tooth and the wrench body umbrella tooth field of conjugate action 14, extension bar 15, sleeve 16, bolt 17, nut
The specific embodiment:
Fig. 1 is an assembly structure figure of the present utility model.Driving member main shaft (6) is inserted in the driving member spindle hole (1) of wrench body (11) among the figure.Volute spring (3) is enclosed within on the driving member main shaft (6), at last punching press shell (2) is buckled on volute spring (3) and the driving member bevel gear (7), driving member spindle hole (1) on the punching press shell (2) is enclosed within on the driving member main shaft (6), and the screw thread (8) on punching press shell (2) and the wrench body (11) is screwed.Thereby assembly cost utility model---big torsion speeder wrench.
Fig. 2 is a cut-away view of the present utility model.Can clearly recognize by Fig. 2: the situation of the field of conjugate action (13) of the wrench body bevel gear (9) on driving member bevel gear (7) and the wrench body (11).And the load condition of punching press shell (2) and volute spring (3) and driving member bevel gear (7).Also have punching press shell (2) and wrench body (11) to go up the assembling situation of screw thread (8).Spacing steel ball (5) among Fig. 2 is to make driving member side's tenon (4) play the fixedly device of position-limiting action when being connected with extension bar (14) or sleeve (15) with spring (12).
In Fig. 3, the speeder wrench that wrench body (11) handle (10) punching press shell (2) constitutes is connected by the square hole of driving member side's tenon (4) with extension bar (14).Extension bar (14) is connected with sleeve (15), thus the screw thread of can tight a bolt (16) and nut (17).If wanting to unclamp bolt (16) and nut (17) need only exchange lower transmission component side's tenon (4) the speeder wrench upset to get final product.
Claims (5)
1, a kind of big torsion speeder wrench is made of shell, spring, driving member and wrench body.It is characterized in that: the cross section of the tooth of the bevel gear of driving member and wrench body is a triangle.
2, according to right 1 described big torsion speeder wrench, it is characterized in that: driving member is connected with wrench body.
3, according to right 1 described big torsion speeder wrench, it is characterized in that: the shell of bearing spring elastic force, by screw thread or withhold with wrench body and realize being connected.
4, according to right 1 described big torsion speeder wrench, it is characterized in that: cross section is that leg-of-mutton tooth is made one on handle, wrench body and the main body.
5, according to right 1 described big torsion speeder wrench, it is characterized in that: with driving member bevel gear, cross section is that the square tenon of leg-of-mutton tooth, driving member main shaft, transmission torque is made one.
