Abstract
Fast adjustable spanner with high torsion belongs to a hardware tool. The existing adjustable spanner has the disadvantages that the speed of adjusting the fixed blocks is slow, and the torsion bearing capacity is low. The fast adjustable spanner comprises a handle, a fixed block arranged at the front end of the handle and integrated with the handle, a movable block arranged at the front end of the handle and capable of moving relative to the fixed block to adjust the distance with the fixed block, and a rotatable adjusting roller arranged at the front end of the handle, wherein, the adjusting roller and the movable block can realize the regulation and the self locking on the movable block by the adjusting roller through helix teeth respectively arranged on the adjusting roller and the movable block. The utility model is characterized in that the helix teeth respectively arranged on the adjusting roller and the movable block are numbered at least two; the speed of regulating the movable block is improved and the torsion bearing capacity is enhanced through the increase in the numbers of the helix teeth on the adjusting roller and the movable block; and furthermore, due to the adoption of the spring acting on the adjusting roller and exerting force in the direction of keeping the movable block far away from the fixed block, the shifting motion of the adjusting roller is avoided, and the reliable force bearing of the movable block and the adjusting roller can be ensured during the clamping.
Description
Technical field
The utility model belongs to hardware ﹠ tools, a kind of specifically adjustable wrench.
Background technology
Existing adjustable wrench, on adjusting roller and movable block, set up the spiral tooth that cooperatively interacts separately, be used for clamping or unclamping workpiece with the distance of regulating between movable block and the fixed block by the adjusting roller that rolls, and divide the spiral tooth that is located on adjusting roller and the movable block to be single head, a number that is the spiral tooth is at least 1, so causes the speed torsion slow, that bear of existing adjustable wrench adjusting fixed block little.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition be overcome existing adjustable wrench regulate the speed of fixed block slow, bear the little defective of torsion, a kind of big torsion rapid adjustable wrench is provided.For this reason, the utility model is by the following technical solutions:
Big torsion rapid adjustable wrench, comprise handle, be linked as whole fixed block at the handle front end and with handle, be installed in handle front end can relative to described fixed block move with regulate and fixed block between the movable block of distance and the rotating adjusting roller of front end that is installed in handle, described adjusting roller is regulated the adjusting and the self-locking of pair of rollers movable block with movable block by the realization that cooperates of setting up spiral tooth thereon separately, it is characterized in that: divide a number that is located at the spiral tooth on described adjusting roller and the movable block to be at least 2.
The beneficial effects of the utility model are: accelerate to regulate the speed of movable block by increasing a number of regulating the spiral tooth on roller and the movable block, increase and bear torsion; Further, by avoiding regulate roller play to movable block away from the spring of the direction application of force of fixed block in the effect of regulating on the roller, thereby movable block when guaranteeing to clamp, to regulate roller reliably stressed.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the K-K of Fig. 2 is to cutaway view.
Fig. 4 is the another kind of view of structure shown in Figure 3.
Among the figure: the 1-handle, the 2-fixed block, the 3-movable block, 4-regulates roller, 51/52-spiral tooth, 6-bearing pin, 7-spring.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in further details.
Big torsion rapid adjustable wrench shown in Fig. 1-4, but it comprise handle 1, handle 1 front end and and handle 1 is linked as whole fixed block 2, the front end relative fixed piece 2 that is installed in handle 1 move with regulate and fixed block 2 between the movable block 3 of distance and the rotating adjusting roller 4 of front end that is installed in handle 1, adjusting roller 4 is regulated the adjusting and the self-locking of 4 pairs of movable blocks 3 of roller with movable block 3 by the realization that cooperates of setting up spiral tooth 51,52 thereon separately, and dividing a number that is located at the spiral tooth on adjusting roller 4 and the movable block 3 is 2 (being the twin-feed spiral tooth).
As to further the improving and replenishing of technique scheme, the utility model also comprises the technical characterictic that following each section is additional, so that independent or combine arbitrarily and be applied to technique scheme when stating technical scheme on the implementation:
Regulate roller 4 and be installed in the front end of handle 1 by bearing pin 6,6 of this bearing pins are connected by the front end of screw thread with handle 1.
Act on the spring 7 of oriented movable block 3 on the adjusting roller 4, also conflict on the bearing pin 6 in the front end of handle and the helical pressure on the adjusting roller for being enclosed within shown in the figure away from the direction application of force of fixed block 2.
Movable block is slidingly mounted on the handle front end.
Design considerations of the present utility model is:
1, pitch diameter of thread d:d=d1-0.5p
2, lead angle α: tan α=(n*p)/(π * d)
3, screw-down torque M:M=F*d/2=(d/2) * Ctan (α+φ e)
In above-mentioned 3 formulas: P is a pitch, and d1 is the roller external diameter, and φ e is an equivalent friction angle, and F is a horizontal applied force, and Q is the vertical loading, n be number of starts (1,2,3 ...).
With 10 " spanner is an example; under the prerequisite that does not change adjustable wrench work head bulk; the lead angle α of the utility model adjustable wrench=12 °; be 2 times of the lead angle of existing adjustable wrench; so the translational speed of movable block is fast, force-bearing situation good, auto-lock function is intact, increase the cost of manufacturing; after tested, the limit torsion of the existing adjustable wrench of the limit torsion of the utility model adjustable wrench has increased by 15%～20%.
