Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further.
Locking adjustable wrench of the present utility model, as shown in Figure 1, comprise handle 01, form the stationary gripping part 03 of clamp port 02 between, movable clamping part 04, one made by stationary gripping part 03 and handle 01, movable clamping part 04 is slidably assemblied in stationary gripping part 03, movable clamping part 04 is provided with worm-gear toothing 41, the worm screw 51 be assemblied in stationary gripping part 03 realizes loosening for driving movable clamping part 04 to realize clamping or leave stationary gripping part 03 near stationary gripping part 03 by engaging with worm-gear toothing 41, stationary gripping part 03 is provided with the retaining part 06 that to match with worm screw 05, worm-gear toothing 41 when retaining part 06 and worm screw 05 are provided with the backing stop structure that cooperatively interacts in order to clamp on prevention activity clamping part 04 orders about worm screw 05 to loosening direction action.
During use, make worm screw rotate by stirring worm screw 05, driving activity clamping part 04 realizes clamping near stationary gripping part 03 or leaves stationary gripping part realizing loosening.During clamping, especially when pulling handle, movable clamping part is subject to the active force to loosening direction, and this active force is delivered on worm screw by worm-gear toothing, general, utilizes the self-locking of worm and gear that movable clamping part can be stoped to move to loosening direction.Rely on structure of the present utility model, worm-gear toothing on backing stop structure prevention activity clamping part on retaining part and worm screw orders about worm screw to loosening direction action, therefore worm screw is located, even if now the self-lock ability of worm and gear is not enough to prevention activity clamping part and moves to loosening direction, but being located by means of worm screw stops movable clamping part to loosen, keep clamping; And knock the impact that handle causes when using and also can not destroy clamping.
For making structure simple, backing stop structure comprises and is divided into retaining part 06 and the termination, location 61 on worm screw 05 and locating slot 51, as shown in Figure 1, termination 61, location is positioned at the end of retaining part 06, locating slot 51 is located on worm screw 05, and when specifically implementing, the two can transposition, during location, termination 61, location is positioned at locating slot 51 and stops worm screw 05 to be rotated.Locating slot 51 is multiple, and the plurality of locating slot is located at the end face of worm screw and is circularly and evenly distributed.Although termination, illustrated location is one, during concrete enforcement, termination, location can be uniform 2-3.During in order to ensure clamping, worm screw can by flexible operating, and worm screw 05 can axially movablely be assemblied in stationary gripping part 03, thus worm screw 05 can be made to move axially a distance confession backing stop structure get loose when stirring worm screw 05.Further, worm screw 05 acts on the 07(that has elastic component and is illustrated as in one end of worm screw by being supported with spring), the elastic force of flexible member makes backing stop structure be combined together.
Structure of the present utility model is particularly useful for the worm screw of bull number.General, the head number of worm screw is that 2-3(is illustrated as 2).
A worm gear clamping loosening configuration is related in locking adjustable wrench of the present utility model, it is included in the stationary gripping part 03 forming clamp port 02 therebetween, movable clamping part 04, movable clamping part 04 is provided with worm-gear toothing 41, worm screw 05 realizes loosening for driving movable clamping part to realize clamping or leave stationary gripping part near stationary gripping part by engaging with worm-gear toothing 51, retaining part 06 is equipped mutually with worm screw, worm-gear toothing when retaining part 06 and worm screw 05 are provided with the backing stop structure that cooperatively interacts in order to clamp on prevention activity clamping part orders about worm screw to loosening direction action.
Same, backing stop structure comprises and is divided into retaining part 06 and the termination, location 61 on worm screw 05 and locating slot 51.Locating slot is multiple, and the plurality of locating slot is located at the end face of worm screw and is circularly and evenly distributed.Worm screw can axially movable configuration and on described worm screw effect have elastic component 07.Further, the elastic force of flexible member makes backing stop structure be combined together.Movable clamping part, worm screw, retaining part are assemblied in described stationary gripping part.The head number of worm screw is 2-3.
