Abstract

The utility model relates to a self-adjustable spanner for sliding block devices, composed of a fixed frame (1), a sliding block (2), a connecting rod (3), an operating lever (4) and a spring (5), wherein, the sliding block (2) is installed in a sliding block groove (8) of the fixed frame (1), and the operating lever (4) is gripped by hand (pressing looseness and recovery). The sliding block (2) can slide in and out in the sliding block groove (8) for matching with the tension acting of the spring (5) under the push of the connecting rod to achieve the continuously rotating function of the spanner. The utility model has the advantage that the utility model can automatically regulate various (within a definite range) screw nuts (bolts) and can operate continuously, and because the utility model has a directly inserted type front part, the utility model has the advantages of strong working environment adaptability and convenient operation.

Description

Sliding plug block assembly self-adjusted spanners

The utility model belongs to mechanical hardware ﹠ tools.

Before the utility model came out, the spanner that sell in market had Wrench commonly used such as adjustable wrench, back-up wrench, double offset ring spanner.Also owe convenient in the use, thereby spanner is comparatively easily used in the design design.Sliding plug block assembly self-adjusted spanners is than convenient in the use with upper ejector lever.Can regulate all size nut (bolt) of (in the certain limit) automatically, self-regulated is used fully.For realizing this scheme, the outer appearnce of this spanner is like back-up wrench, and the major technique feature is by (1) two identical symmetrical mounting of fixed mount, slip chock (2), and connecting rod (3), action bars (4), spring (5) is formed.Fixed mount (1) feature is that symmetrical two is shaped on different size jaw (7) separately, slide block slot (8), and fixedly clamp (6) is the monolithic molding manufacturing.

Its operation principle: hold tight action bars (4), this moment, action bars was in the pressing state, made slip chock (2) push jaw (7) to by the promotion of connecting rod.Form active clamp (15) state, constituted spanner binding nut (bolt) flame mode.This state energy binding nut (bolt) is arbitrarily along contrary direction rotation, when loosening action bars, since the tension force effect of spring (5), the action bars of upspringing (4), transmission through connecting rod (3), move big disappearance of jaw on the active clamp (15) that slip chock (2) is pulled back make formation.Nut (bolt) space of rotation arbitrarily occurred, nut can not collide reversing during the displacement orientation.Repetitive process is finished the spanner function like this.

Major advantage of the present utility model can be used for the automatic adjusting of the nut (bolt) of different size (in the certain limit), and the operating efficiency height is easy to use, and certain popularizing value is arranged.

Now be described below in conjunction with the accompanying drawings: Fig. 1 is this novel structure chart, made broken section among the figure, slip chock (2) is installed in the loose piece groove (8) of fixed mount (1), connecting rod (3) and action bars (4) are linked, (5) belows that are loaded on action bars (4) of spring, one is contained on the fixed mount (1).Fixedly clamp (6) opposite face is active clamp (15).Fig. 2 is the overall diagram of fixed mount (1), has made broken section among the figure, shown in the jaw (7) of two identical symmetries, slide block slot (8) is gone up connecting rod axis hole (9), lower link axis hole (10), fixedly clamp (6) is the integral body manufacturing.Fig. 3 is the overall diagram of slip chock (2), shown in step patch (14) and slip chock disjunctor make.(11) garden shape activity orientation bar and slip chock disjunctor are made.Connection handle (12) connects delthyrium (13).Fig. 4 is the right view of slip chock overall diagram, shown in step patch (14), garden shape activity orientation bar (11).

Claims

1, sliding plug block assembly self-adjusted spanners, form by fixed mount (1), slip chock (2), connecting rod (3), action bars (4), spring (5), its principal character: fixed mount (1) is provided with the jaw (7) of identical symmetry, fixing clamp (6), slide block slot (8), interior dress slip chock (2) slippage, coupler link (3), action bars (4), spring (5).

2, according to described in the claim 1, sliding plug block assembly self-adjusted spanners is characterized in that fixed mount (1), slip chock (2), connecting rod (3), action bars (4), spring (5) composition, can the single head structure make, can the bipitch structure manufacturing.
