Abstract

The utility model relates to a pulley positioning structure, comprising a pulley rotary arranged on the lateral face of the base by the pin roll, and a moving part body used for locating the base. The utility model is characterized in that: a projection is arranged on the other lateral face of the base, and a through hole is arranged on the moving part body corresponding to the projection, and the projection is clamped with the connection block through the through hole. Compared with the prior art, the utility model has the advantages of enabling to rapidly achieve the location by using the projection clamped with the connection block after penetrating the through hole and without using other tools, therefore having convenient, easy and rapid assembling. A spring is positioned between the side of the via hole and the projection, enabling the base and the connection block move against the side of the via hole; thus the pulley can regulate the height in moving by the compression or extension of the spring, so as to overcome the movement disorders resulting from the various errors and finally make the push-drawing movement of the moving part more flexible.

Description

A kind of pulley location structure

Technical field

The utility model relates to a kind of pulley location structure, specifically refer to a kind of should be in the pulley location structure on the moving members such as sliding door, window.

Background technology

At present, on moving members such as sliding door, window, need move by pulley usually, as Chinese notice of authorization number for " the sliding door Hanging roller " of 2366535Y just disclosed so a kind of pulley gear, this pulley is arranged on the pulley base by bearing pin rotationally, the lower end of pulley base is provided with junction plate, and this junction plate is connected by mounting screw and sliding door again.During use, utilize pulley slip in orbit, can realize the purpose that moving members such as sliding door, window easily slide.

But find after its structural analysis, locate such pulley and realize, can waste time and energy by this operating type that inefficiency is difficult to realize the demand of assembling fast by screwing or unscrew mounting screw.Simultaneously, such location structure also can't make pulley regulate height voluntarily in sliding process.Therefore in actual use, under the influence of foozle and rigging error, above-mentioned defective will cause that the push-and-pull feel is heavy, push pull maneuver underaction drawback freely, when serious even stuck phenomenon takes place.

Summary of the invention

First technical problem to be solved in the utility model is the situation at prior art, provides a kind of easy to assembly, the pulley location structure that packaging efficiency is high.

Second technical problem to be solved in the utility model is the situation at prior art, provides a kind of both easy to assembly, can regulate the pulley location structure of pulley height again in slipping voluntarily.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this pulley location structure comprises by bearing pin and is arranged on the pulley on pedestal one side rotationally and is used for the moving member body of positioning pedestal, it is characterized in that: also have a projection on the another side of described pedestal, and to should having through hole on the above-mentioned moving member body of projection, described projection runs through behind this through hole and contiguous block clamping mutually.

As further improvement of the utility model, between described through hole edge and projection, can also be provided with and make pedestal and contiguous block have the spring of this through hole edge side shifting trend dorsad all the time.The location of this spring can be realized in the following manner: described projection is provided with the locating hole that stretches into for above-mentioned spring one end, and extends the reference column that is inserted in for the above-mentioned spring other end at edge, described logical limit.Also can on projection, be provided with same reference column and realize the location.In this scheme, can also on contiguous block, be provided with the baffle plate that offsets with moving member body edge simultaneously, can make spring be in compressive state like this, be integral to guarantee that contiguous block and projection are close to.

In such scheme, described projection cross section can be designed to horizontal T word shape, and described contiguous block is provided with the draw-in groove that matches with this T font projection.Also can be designed to other interface arrangment.

As another kind of improvement the of the present utility model, both sides, described pedestal another side can also be provided with guide strip, then is provided with the gathering sill that is complementary with each limiting plate on described moving member body, to guarantee that pedestal can move up and down reposefully.

Compared with prior art, because the utility model tool free,, just can realize the location apace as long as utilize projection on the pedestal to run through behind the through hole and the contiguous block clamping, therefore assemble up conveniently, easily, quick.The spring of setting up simultaneously makes pulley in sliding process, by means of the compression or the stretching, extension of spring, can automatically regulate the height of self, thereby has overcome the dyskinesia that various error is brought preferably, and the push-and-pull campaign that finally makes moving member more nimbly and freely.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, this shower house comprise by profile structure get on the right track 1, lower railway 2, left column 3, right column 4 and pulley location structure and waterproof film 5, wherein, waterproof film 5 one sides are wound on the spring shaft, and be hidden in the right column 4, the opposite side of waterproof film 5 is pulled out from the cannelure of right column, and is connected mutually with mobile column 6.Described pulley location structure is positioned at the upper and lower end of this mobile column, because two cover pulley location structures are identical, be that example is illustrated now with the pulley location structure that is positioned at the mobile column upper end, this pulley location structure comprises pedestal 8, pulley 9, contiguous block 7 and spring 10, pulley 9 is arranged on the side of pedestal 8 rotationally by bearing pin, have a projection 81 on the another side of pedestal 8, the cross section of this projection is horizontal T font.Described contiguous block 7 is provided with the draw-in groove 71 that matches with this projection 81, simultaneously on should the moving member body of projection, promptly has through hole 61 on the mobile column 6, and projection 81 runs through draw-in groove 71 clamping mutually on these through hole 61 backs and the contiguous block.

In sliding process, regulate height up and down voluntarily in order to make pulley, in the present embodiment, also be provided with between through hole upper edge and the projection and make pedestal and contiguous block have the spring 10 of this through hole upper edge side shifting trend dorsad all the time, consider the location of spring, here, projection is provided with the locating hole 82 that stretches into for above-mentioned spring one end, and extends the reference column 62 that is inserted in for the above-mentioned spring other end on logical 61 upper edges, limit.On contiguous block, also be provided with simultaneously the baffle plate 72 that offsets with the mobile column edge.By compression spring 10, guarantee that contiguous block 7 is tight against mutually with projection 81, is integral and both are close to like this.

Simultaneously also be respectively equipped with guide strip 83, on mobile column 6, then be provided with the gathering sill 63 that is complementary with each guide plate, utilize guide strip moving in gathering sill, make moving up and down of pedestal more steady in both sides, top, pedestal 8 another side.

During assembling, earlier spring 10 1 ends are inserted in the locating hole 82 of projection, the other end with spring 10 is enclosed within outside the reference column 62 of through hole upper edge then, simultaneously projection 81 is inserted in the through hole 61, with doing the inserting action after 71 alignment bumps 81 of the draw-in groove on the contiguous block, can finish assembling at last.
