Abstract

The utility model discloses a mistaken-locking prevention device of a casement window, which belongs to the field of hardware fittings, and comprises a sliding rod (5) and a mounting piece (1). A limiting block (6) is arranged on the sliding rod, a through groove (8) is disposed on the mounting piece, and the sliding rod penetrates through the through groove (8). The mistaken-locking prevention device is characterized in that a chute (10) is disposed on the mounting piece, a sliding sheet (2) capable of sliding is arranged in the chute, a bump (7) is disposed on the bottom surface of the sliding sheet, a spring (4) is disposed on the mounting piece, one end of the spring contacts with the sliding sheet, a contact sheet (3) is disposed at the end, which contacts with the spring, of the sliding sheet, and a right angle is formed between the contact sheet and the sliding sheet. By the aid of the mistaken-locking prevention device with the structure, a lock rod on a window sash cannot be shifted by a shifting fork even when a handle is wrenched when the window sash is open, and accordingly the mistaken-locking prevention device can prevent mistaken operation to damage locking points on a window sash when the window sash is collided to a window frame caused by artificial reasons or blowing wind, and effectively protects the window sash.

Description

The anti-error locking device of casement window

Technical field

The utility model relates to the Hardware fitting on a kind of casement window, what be specifically related to is a kind of a kind of device that prevents the handle maloperation.

Background technology

Casement window is used on building a lot, and it can be put down out, and it is big to make sash open scope, ventilates soon with the external world, thereby is subjected to users' welcome.These windows make sash open fully when flat opening; After sash was opened, each lock point on its sash all broke away from the position-limit mechanism on the window frame fully.But sometimes, particularly use the not really user of custom, after opening sash, also will pull handle, this, handle just can rotate shift fork and change lock a little position of sash, if close window this moment, these lock points will bump with the position-limit mechanism on window frame or the window frame, particularly when blowing, more are easy to generate collision, like this, lock point on the sash is easy to be collided and damages, and when serious, incrusted glass also can be collided and shatter on the sash; If the lock point on the sash damages, repair very trouble, serious also will change sash.

Summary of the invention

In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides and a kind ofly can prevent handle malfunction on the sash and cause the flat back of opening to change the lock anti-error locking device of casement window a little of sash.

For this reason, the utility model adopts following technical scheme to realize: a kind of anti-error locking device of casement window, comprise sliding bar and fixing body, described sliding bar is provided with limited block, has the groove that passes for described sliding bar on the described fixing body, it is characterized in that on described fixing body, being provided with chute, in described chute, be provided with the slide that can slide, bottom surface at described slide is provided with projection, on described fixing body, be provided with spring, one end of described spring contacts with described slide, has contact at described slide with the end that described spring contacts, described contact and the slide shape that meets at right angles; One end of described chute is provided with block piece.

This structure of the present utility model; after window is put down and is opened under putting down; because each the lock point on the sash breaks away from the position-limit mechanism on the window frame fully; and the contact of slide upper end moves under the effect of spring; make the projection of slide bottom move, just in time be stuck on the limited block on the sliding bar, because sliding bar links to each other with locking bar on the sash; like this; sash is pulled handle after putting down and opening once more, just can't rotate; also just can't change the lock point on the locking bar; when blowing or when closing window, the lock point on the sash locking bar just can enter the position-limit mechanism on the window frame again, and sash and window frame just can not bump; protected the lock point on the sash effectively, and the whole fan of protection sash.

Description of drawings

Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.

Fig. 1 is overall structure figure of the present utility model; Fig. 2 is an explosive view of the present utility model; Fig. 3 is the structure chart at the utility model Fig. 1 back side; Fig. 4 is the structure chart of the utility model sliding bar;

The specific embodiment

With reference to accompanying drawing, the anti-error locking device of this casement window, comprise sliding bar 5 and fixing body 1, described sliding bar 5 is provided with limited block 6, has the groove 8 that passes for described sliding bar 5 on the described fixing body 1, described fixing body 1 is provided with chute 10, in described chute 10, be provided with the slide 2 that can slide, be provided with projection 7 in the bottom surface of described slide 2, limited block 6 couplings on this projection 7 and the sliding bar 5 are provided with spring 4 on described fixing body 1, one end of described spring 4 contacts with described slide 2, the other end contacts with described projection 7, has contact 3 at described slide 2 with the end that described spring 4 contacts, described contact 3 and slide 2 shape that meets at right angles; One end of described chute 10 is provided with block piece 9.During this anti-error locking device assembling, the block piece 9 of chute 10 1 ends is removed, put into spring 4 on the fixing body 1 after, again slide 2 is inserted chutes 10, then block piece 9 is inserted draw-in grooves 11, like this, slide 2 just can not come off with spring 4.After installing, when being installed in it on sash, its sliding bar 5 is connected with locking bar on the sash, constitutes an anti-error latch mechanism.Pull handle, the pulling locking bar makes sash be in and puts down when opening state, lock point on the locking bar just breaks away from the position-limit mechanism on the window frame, at this moment, because the effect of the spring 4 on the fixing body 1, promote slide 2 and move, make that the projection 7 on the slide 2 just blocks sliding bar 5 upper limit position blocks 6, therefore, at this moment, pull handle again, just can't spur locking bar, also just can't change the lock point on the locking bar, prevent owing to mistake is pulled the position that handle changes lock point, produce collision and cause the sash damage with sash when closing window.And will close window the time, close sash is flat, the lock point on the sash can correctly enter the position-limit mechanism on the window frame, and the contact 3 on the slide 2 since with slide 2 shape that meets at right angles, just, on sash, exert oneself a little, just slide 2 is moved by contact 3 with the window frame coupling, make the limited block 6 that projection 7 on the slide 2 breaks away from the sliding bars 5, at this moment, pull handle once more, just can spur locking bar, make lock point on the locking bar block the position-limit mechanism on the window frame, reach the purpose of closing window.
