CN210714192U - Anti-unlocking lock with double-safety for sliding door and window - Google Patents

Abstract

The utility model discloses a push-pull door and window anti-unlocking lock with double insurance, which comprises a bottom plate, a face cover, a sliding piece and a limit baffle, wherein the front end of the sliding piece is provided with a limit block, when the limit baffle is in a pulling-up vertical state, the limit block is pushed out by the sliding piece to respectively block the two limit blocks outside the two limit baffles, so as to form a blocking structure for preventing the limit baffles from being flattened; when the limiting baffle is in a leveling state, the limiting blocks are pushed out through the sliding parts to enable the two limiting blocks to be respectively blocked on the upper surfaces of the two limiting baffle, and a blocking structure for preventing the limiting baffle from being pulled up is formed. Therefore, the double-safety effect can be achieved, namely, the limiting baffle can be leveled only when the sliding piece slides backwards to the bottom in the opening prevention state, so that children cannot easily learn the opening operation; meanwhile, the limiting baffle can be erected only when the sliding part slides backwards to the bottom in the non-opening-prevention state, and the situation that the door and window cannot be opened due to the fact that the lockset is automatically opened due to accidents when the opening is not required to be prevented can be prevented.

Description

Anti-unlocking lock with double-safety for sliding door and window

Technical Field

The utility model relates to a furniture accessory product technical field, concretely relates to be used for fixing on plug-type door and window in order to prevent that door and window is opened by children prevents opening tool to lock.

Background

The sliding door or the sliding window has the advantages of convenience in use and small occupied space, but has the defect of easiness in opening, and accidents that children climb out of the window to be clamped on the anti-theft net due to unclosed windows are frequently reported in the society. One of the main reasons that sliding doors and windows are not closed frequently is the inconvenience of locking, and for this reason, some locks for preventing children from opening have been invented, for example, a novel sliding door and sliding door limiting device disclosed in patent CN201820511542.9, which is adhered to a door or a window, and when the door or window is not to be opened, the limiting plate is erected to block the door or window on one side, thereby achieving the effect of preventing opening. When the anti-opening is not needed, the two limiting plates are directly leveled. However, this lock has a disadvantage in that, since the child has curiosity and strong imitation ability, when seeing that the adult presses the limit plate and then opens the drawer, the child can easily learn to open the door and window, resulting in loss of the opening prevention effect.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the defect to prior art existence, provide a simple structure, design more reasonable, can prevent more effectively that children from opening door and window, can also prevent more effectively simultaneously when need not prevent opening that the tool to lock is opened the locking state because of the accident and is caused troublesome plug-type door and window with dual fail-safe and prevent unblanking.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a plug-type door and window prevents unblanking with dual fail-safe, including bottom plate, face lid, slider and limit baffle, the slider dress is in the face lid, and the face lid is adorned on the bottom plate together with the slider, and two limit baffle pass through the fixed axle and install the structure that forms rotatable pull-up and tie on the bottom plate with the cooperation of torsional spring, its characterized in that: the front end of the sliding piece is respectively provided with a limiting block extending forwards at two sides, when the limiting baffle is in a pulled-up vertical state, the limiting blocks are pushed out by the sliding piece to respectively block the two limiting blocks at the outer sides of the two limiting baffles, so that a blocking structure for preventing the limiting baffles from being flattened is formed, and at the moment, the door and the window can not be opened; when limit baffle is in the state of leveling, push out the stopper through the slider and make two stoppers keep off respectively at two limit baffle's upper surface, form the block structure that prevents limit baffle pull-up, door and window can normally open and close this moment.

Furthermore, a spring groove seat is arranged on the bottom plate, a spring with the same telescopic direction as the sliding direction of the sliding part is arranged in the spring groove seat, and the sliding part clamps the clamping spring to form a driving structure for automatically pushing the sliding part to slide forwards so as to push the limiting block out.

Furthermore, the front end in the middle of the face cover stretches out forward to form a stop beam, the two limiting baffle plates are symmetrically arranged on two sides of the stop beam, and when the two limiting baffle plates are in a pulled vertical state, the inner side surfaces of the two limiting baffle plates are respectively attached to two sides of the stop beam, so that the vertical state of the limiting baffle plates is more stable, and the blocking effect on doors and windows is better.

Furthermore, the spring groove seat protrudes into the blocking beam, the front end of the middle of the sliding part is provided with a surrounding blocking seat, the surrounding blocking seat and the spring groove seat form a front-back opposite structure, the spring is sleeved in the spring groove formed by the surrounding blocking seat, the front end of the spring abuts against the front end of the surrounding blocking seat, and the rear end of the spring abuts against the spring groove seat. When the sliding part slides backwards, the spring is compressed, the spring has kinetic energy extending forwards, and after the sliding part is loosened, the spring extends to reset the sliding part.

Furthermore, a plurality of studs are arranged on the bottom plate, and the surface cover and the bottom plate are combined and fixed through the studs; the bottom surface of the surface cover is provided with a bottom groove, and the sliding piece is integrally embedded in the bottom groove to form a structure capable of sliding back and forth.

Furthermore, a strip-shaped sliding hole with the same extending direction as the sliding direction of the sliding part is formed in the sliding part, and the stud penetrates through the strip-shaped sliding hole to form a guide structure for the sliding process of the sliding part, so that the sliding part is more stable and smooth in sliding.

Furthermore, a sliding hole is arranged in the surface cover and is communicated with the bottom groove; the surface of the sliding part is provided with a sliding button which protrudes upwards in the sliding hole, and the sliding button is only required to be pressed to slide when the limit baffle is unlocked.

Furthermore, a clamping groove is respectively arranged in the bottom plate and the limiting baffle, and two ends of the torsion spring are respectively clamped in the clamping grooves of the bottom plate and the limiting baffle, so that the assembly structure is simple and effective and is easy to realize.

The utility model discloses a set up two stoppers at the front end of slider, can be used to carry on spacing respectively to two limit baffle when setting up and tie the state, play the effect of dual fail-safe, namely prevent that the open mode can only tie up with the limit baffle when sliding the slider backward to the end, so children are difficult to learn the operation of opening, reach more effective opening prevention function; meanwhile, when the sliding part is not prevented from opening, the limiting baffle plate can be erected only when the sliding part slides backwards to the bottom, so that the problem that the door and window cannot be opened due to the fact that the lockset is automatically opened due to accidents when the sliding part is not prevented from opening can be avoided, and troubles are brought to users.
