Abstract
The utility model relates to a quick socket wrench. The utility model comprises a handle, a housing, a sleeve barrel, a ratchet wheel ratchet, a pair of positive ratchet block and reverse ratchet block, a turning cam for a positive ratchet block, a turning cam for a reverse ratchet block, a deflector rod, a return spring, and a movable seat for a ratchet block, wherein, the movable seat is arranged in a cylindrical hole with a step on the back side of the housing; the rotating shaft of the positive ratchet block and the rotating shaft of the reverse ratchet block are inserted on a shaft hole on the bottom of an L-shaped connecting block on the front end of the movable seat and a groove on the lateral surface of the L-shaped connecting block on the front end of the movable seat; a check ring and a spring are sheathed on the movable seat whose back diameter is smaller; the back end of the spring is provided with a regulating nut which is connected with screw threads on the inner wall of the housing. The utility model whose moment of force can be arranged in advance can guarantee that the assembly of members conforms to the requirements of construction and the requirements of an acceptance check standard.
Description
The utility model relates to a kind of fastening hand tools that is used for, particularly a kind of quick box spanner.
In some installing engineerings and manufacturing industry, construction and acceptance specification all have specific requirement to the tightening torque of various securing members.And the various spanners that use at present, mainly be with the user on hand feel to apply moment, do not meet the requirement of standard.A kind of spanner that can show moment is arranged, complex structure, the cost height, pulling will often stop in the process looks at the moment values that shows, and speed of application is slow, and work efficiency is low.
At present, a kind of quick box spanner is arranged, it is formed and mainly comprises handle, housing, sleeve, ratchet (having square toes), a pair of forward and reverse ratchet piece and commutation cam thereof, driving lever, back-moving spring, the rotating shaft of ratchet piece is arranged in the groove of housing, stir the commutation cam by driving lever, make forward ratchet piece or oppositely ratchet piece and hook tooth engagement, only need the waggle handle, just can apply the moment fastening nut or unscrew nut.The shortcoming of this quick box spanner is to preestablish screw-down torque, the standard that can not satisfy construction and check and accept.
The purpose of this utility model is, overcomes the above-mentioned shortcoming of existing box spanner, and a kind of quick box spanner that can preestablish screw-down torque is provided.
The purpose of this utility model realizes by following technical solution: a kind of quick box spanner, its composition comprises handle, housing, sleeve, ratchet, a pair of forward and reverse ratchet piece and commutation cam thereof, driving lever, back-moving spring, it is characterized in that having ratchet piece sliding seat, this sliding seat places housing rear side cylindrical hole with the level, just, oppositely insert in the bottom axis hole and lateral groove of sliding seat front end " L " shape contiguous block on the rotating shaft limit of ratchet piece, sliding seat rear portion diameter is less, be with back-up ring on it, spring, spring rear end has adjusting nut, and adjusting nut is threaded with inner walls.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 looks (analysing and observe) figure for the utility model overall structure master.
Fig. 2 overlooks (analysing and observe) figure for the utility model overall structure.
Fig. 3 is a ratchet piece stereogram of the present utility model.
Fig. 4 is a ratchet piece sliding seat stereogram of the present utility model.
As depicted in figs. 1 and 2, the composition of the quick box spanner of the utility model comprises handle 7, housing 6, sleeve (not drawing among the figure), ratchet 1, a pair of forward and reverse ratchet piece 3,13 and the commutation cam 2, driving lever 8, back-moving spring 12,14, ratchet piece sliding seat 5 places housing rear side cylindrical hole with the level, just, reverse ratchet piece 3, insert in the bottom axis hole of sliding seat 5 front ends " L " shape contiguous block 4 and the lateral groove (referring among Fig. 4 shown in 17 and 16) on 13 rotating shaft limit (referring among Fig. 3 shown in 15), at commutation cam 2, driving lever 8, back-moving spring 12, under 14 the effect, forward and reverse ratchet piece 3,13 can be in the groove of " L " of sliding seat 5 shape contiguous block 4 the certain angle of deflection, not side by side with ratchet 1 on ratchet engagement, sliding seat 5 rear portion diameters are less, be with back-up ring 9 on it, spring 10, spring 10 rear ends have adjusting nut 11, and adjusting nut 11 is connected with housing 6 inner threads.
15 is ratchet piece rotating shaft limit among Fig. 3.
4 is sliding seat front end " L " shape contiguous block among Fig. 4, and the contiguous block bottom has axis hole 17, and the side has groove 16.
During use; earlier give the spring 10 on the sliding seat 5 certain preload pressure by adjusting nut 11; just set moment of torsion to box spanner; when with this box spanner fastening nut; its screw-down torque is by ratchet 1 tooth; ratchet piece 3 is passed to sliding seat 5; spring 10; adjusting nut 11; again to housing 6; handle 7; when screw-down torque is increased to the moment of torsion of being about to surpass to set; tooth on the ratchet 1 will overcome the preload pressure of sliding seat 5 upper springs 10; promoting ratchet piece 3 moves backward together with sliding seat 5; cause the spring on the sliding seat to be compressed certain distance again; tooth tooth top up to ratchet slips over ratchet piece 3 ends; ratchet piece 3 resets to the bottom of next hook tooth under the elastic force of sliding seat upper spring 10 promotes, screw-down torque disappears, thereby reaches the qualification moment of torsion; the effect of protection securing member.
Regulate the preload pressure of sliding seat upper spring 10, also just regulate the moment of torsion that presets of box spanner, like this, both can guarantee to reach the required moment of torsion of fastening nut, guarantee can not surpass the moment of torsion of this setting again, thereby guarantee that the member assembling meets the requirement of construction and acceptance specification.
Among the embodiment, the spring 10 on the sliding seat adopts the disk spring group, and little because of its distortion, elastic force is big, does not increase the volume of box spanner.
Claims (2)
1, a kind of quick box spanner, its composition comprises handle, housing, sleeve, ratchet, a pair of forward and reverse ratchet piece and commutation cam thereof, driving lever, back-moving spring, it is characterized in that having ratchet piece sliding seat, this sliding seat places housing rear side cylindrical hole with the level, insert in the bottom axis hole and lateral groove of sliding seat front end " L " shape contiguous block on the rotating shaft limit of forward and reverse ratchet piece, sliding seat rear portion diameter is less, be with back-up ring, spring on it, spring rear end has adjusting nut, and adjusting nut is threaded with inner walls.
2, quick box spanner according to claim 1 is characterized in that the spring on the sliding seat adopts the disk spring group.
