Description

The locking device that a kind of curtain rail is used

The utility model relates to the technical field of window shade arrangement, particularly limits the locking device of pulley operational limit position in the guide rail.

When pulley sleeve was loaded on the curtain rail, for anti-limited slip wheel is run out of from the two ends of guide rail, traditional structure was at the two ends of guide rail muzzle envelope plastic end cover.If but curtain is very big, the span of guide rail is very big, be inadequate only in guide rail two ends cover envelope, if do not limit the operational limit position of curtain roller artificially, curtain folds, opens and all becomes very messy, unordered so, and is also not attractive in appearance.How to make things convenient for, limit easily again attractive in appearancely the position of pulley, conventional art is not too many to be noted, only adopts modes such as the most original stitching, buckle that the part pulley is fixed, and causes that curtain is not attractive in appearance, folding is regulated inconvenient.

The purpose of this utility model is the weak point that overcomes conventional art, provide a kind of simple in structure, use easy to adjust, solid and reliable curtain rail locking device.

The technical solution of the utility model is such: the locking device that a kind of curtain rail is used, be plugged in the pulley walking chamber groove of curtain rail, it is characterized in that: form by " U " shape shell fragment and locking bar, " U " shape shell fragment central authorities have the hole, this hole and the assembling of " U " shape shell fragment are passed in locking bar top, with " U " shape shell fragment is the boundary, locking bar is divided into the projection on top and the handle of bottom, and the width of projection should be less than the width of notch of cavity recess, and the length of projection should be a bit larger tham the width of notch of cavity recess, further, two perk ends of " U " shape shell fragment form the chucking lug that can insert in the notch of cavity recess.

In conjunction with the accompanying drawings and embodiments structure of the present utility model and advantage are being elaborated down.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the schematic diagram behind Fig. 1 locking bar half-twist;

Fig. 4 is the schematic perspective view of Fig. 3;

Fig. 5 is the schematic diagram that the utility model and guide rail unclamp assembling;

Fig. 6 is the schematic diagram of the utility model and guide rail locking assembling.

Referring to Fig. 1-Fig. 4, the curtain rail locking device of present embodiment mainly is made up of " U " shape shell fragment 1 and 2 liang of members of locking bar, and locking bar 2 is divided into the projection 21 on top and the handle 22 of bottom, " U " shape shell fragment 1 central authorities have hole 11, and hole 11 is passed on the top of locking bar 2 and " U " shape shell fragment 1 assembles-and be that locking bar 2 can 11 rotations around the hole.Curtain rail 3 is " worker " word groove class guide rails, its notch 31 narrower, inner chamber groove 32 broads, and the width of the projection 21 on locking bar 2 tops is designed to then be slightly larger than less than the width length of notch 31 width of notch 31; Simultaneously, the width of the chucking lug 12 of " U " shape shell fragment 1 two ends perk is also less than the width of notch 31.Like this, as Fig. 1, state shown in Figure 2, locking device just can be by notch 31 vertical insertions in the curtain rail 3, edge 13 until " U " shape shell fragment 1 contacts (promptly shown in Figure 5) with curtain rail 3, the projection 21 of this moment is in the chamber groove 32, as long as turning handle 22 makes projection 21 also rotate 90 ° thereupon, in the rotary course, the hypotenuse friction and Extrusion of one side projection 21 and notch 31 inwalls, the cambered surface 23 of handle 22 is also pushed " U " shape shell fragment 1 on the other hand, because guide rail 1 has been close at the edge 13 of " U " shape shell fragment 1, so just force the distortion of " U " shape shell fragment 1 local elasticity, thereby make locking bar 2 sting tightly on guide rail 3 (as shown in Figure 6), thereby limit the traffic coverage of pulley together with " U " shape shell fragment 1.When getting loose, need only turning handle 22, make projection 21 half-twists, projection 21 disappears with the extruding of the hypotenuse of notch 31 inwalls, and " U " shape shell fragment 1 is replied original shape, then can take off locking device (as shown in Figure 5), and cancellation is to the restriction of pulley in the guide rail.

The utility model has the advantages that:

1, can be directly packs into or unload locking device from the notch of guide rail, be not subjected to the guide rail two ends The restriction of mouth installs, regulates, uses very easy;

2, simple in structure, lock solid and reliablely, be difficult for getting loose;

3, easy to manufacture, production cost is low.

Claims (2)

1, the locking device used of a kind of curtain rail, be plugged in the pulley walking chamber groove of curtain rail, it is characterized in that: form by " U " shape shell fragment and locking bar, " U " shape shell fragment central authorities have the hole, this hole and the assembling of " U " shape shell fragment are passed in locking bar top, are the boundary with " U " shape shell fragment, and locking bar is divided into the projection on top and the handle of bottom, and the width of projection should be less than the width of notch of cavity recess, and the length of projection should be a bit larger tham the width of notch of cavity recess.

2, locking device according to claim 1, its feature forms the chucking lug that can insert in the notch of cavity recess at the two perk ends that are " U " shape shell fragment.
