Description

The sliding door lockset

The utility model relates to the sliding door lockset.

Always, employed sliding door lockset such as room, window almost major part use as the manufacturing of screw thread convolution.But, the sliding door lockset of this screw thread convolution is through after using for a long time, ridge is understood damaged or is got rusty, the obvious variation of its action meeting, and because be the screw thread combination, so the screwed hole of two fan doors must be consistent, so, its aligning to be located at the screwed hole in the crack between a door and its frame crack that is out of shape through long-time use, just essential sizable strength.

Fig. 1 shows existing a kind of lockset.In Fig. 1, offer on the side wall surface of locking bar 4 and be roughly

The gathering sill 7 of shape, and be provided with along this gathering sill 7 limits and stir the guide peg 8 that moves on the spring limit is provided with hitcher 5 in the right-hand end of locking bar 4, can rotate and hook not shown hook groove.The lockset of this spline structure, swing handle 3, guide peg 8 are at gathering sill 7 internal motions, because the rotation of handle 3, sliding door is finished and locked or unlocking action.

But there are the following problems for above-mentioned lockset, that is, when opening the door, must make handle 3 do full the rotation along the road of gathering sill 7, so, when emergency takes place, just be not easy to finish making handle do full action of rotating.

Problem in view of above-mentioned prior art existence, the purpose of this utility model is, provides a kind of handle that needn't make to do full the rotation, as long as the push switch handle, can open lock easily, can be not nervous when running into disaster such as fire and easily open the sliding door lockset of door or window.

A kind of sliding door lockset that the utility model provides is characterized in that having: the lockset body, described lockset body is provided with and is roughly The gathering sill of shape, this gathering sill are provided with two erection part abreast, and are provided with the rake of the described erection part of connection and the portion of taking refuge of the groove shaped of an end of being located at described erection part; Locking bar, this locking bar cooperates with described lockset body, which is provided with the guide peg that cooperates with described gathering sill, and be connected with described lockset body by helical spring, in an end of described locking bar, can handle be installed rotationally up and down, be provided with rectangular hitcher in the other end.

Brief description:

Fig. 1 is the stereoscopic figure of one of existing sliding door lockset example.

Fig. 2 is stereoscopic figure and the exploded stereogram of the utility model sliding door lockset one embodiment.

Fig. 3 (A) is the open mode lateral view of the utility model sliding door lockset one embodiment.

Fig. 3 (B) is the lateral view of (closing) state of locking of the utility model sliding door lockset one embodiment.

Fig. 3 (C) is the lateral view that the closing motion of the utility model sliding door lockset one embodiment is shown.

Below in conjunction with description of drawings embodiment of the present utility model.

As shown in the figure, the integral unit of the utility model sliding door lockset is arranged to aim at the opening (not shown) of the place ahead door, on the leading flank of the lockset body made from firm materials such as metals 11, be attached with the cover of upholstery 12 that metal or plastics etc. are made, lockset body 11 is roughly columnar ducted body, is formed with in its side to be roughly

The gathering sill 22 of shape.This gathering sill 22 has parallel two erection part 22 ', 22 ", in these two erection part 22 ', 22 " between shown in each figure, be formed with rake 25 and the portion 24 of taking refuge.Leading section side at locking bar 13 uprightly is fixed with guide peg 21.

Locking bar 13 is inserted in the lockset body 11, in an end of locking bar 13, by pivot pin 15 and the mutual axis hole of aiming at 13 " and axis hole 14 ', handle 14 is inserted in the insertion groove 13 ', and can rotate up and down in insertion groove 13 '.

The hitcher 16 of locking bar 13 right-hand end is made microscler, and between locking bar 13 and lockset body 11, strong helical spring 17 combines with its end respectively.Therefore, between locking bar 13 and lockset body 11, the rotating torque effect is arranged.The dog hole 20 that the shape of hitcher 16 and size and fixture with screw and so on are fixed on the hook plate 19 on the outer door is corresponding, swing handle 14 under the hitcher state consistent with the dog hole angle, rectangular hitcher 16 becomes the angle different with dog hole in dog hole 20, promptly be the state of locking.

The rake 25 and the portion 24 of taking refuge of gathering sill 22 play a very important role in the utility model.Below sliding door lockset of the present utility model is described in more detail.

In the time will closing, pushing limit, pull-up handle 14 back makes its rotation, so guide peg 21 moves along gathering sill 22, is introduced into the gathering sill erection part of lower end through rake 25.Hook the hook plate 19 at rear at this state hitcher 16, door promptly is closed.(Fig. 3 B).

When unblanking, as long as squeeze grip, guide peg 21 promptly enters the portion of taking refuge 24, at this state, because the effect of the moment of torsion of upper side in figure of helical spring 17, guide peg 21 turns to rake, the erection part 22 above the guide peg 21 that rake 25 slides is introduced into original section start ", lock promptly is opened.

Be incorporated with on the lockset body 11 of above-mentioned all members, preferably putting the sleeve 10 that material such as metal is made, flowing into advancing of obstruction guide pegs 21 such as foreign matter on body or the door to prevent foreign matter.

Aforesaid sliding door lockset of the present utility model, gone up after the lock, do not need other rotational action just can open lock because only need squeeze grip, so, when emergencies such as breaking out of fire, robber, can be rapidly and open lock exactly, even between dog hole 20 and the hitcher 16 what kind of gap is arranged, can not hinder its action yet, therefore, even sliding door lockset of the present utility model has the advantages that bad, the dog hole 20 of situation of door can not opened lock etc. yet in the tram.
