Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in fig. 1 to 9, a novel lock for a safety grid comprises a lock main body 1, wherein the lock main body 1 comprises a panel 2, and the back of the panel 2 is provided with a mounting groove 3. The both ends of mounting groove 3 are provided with buckling parts 4, and the effect of buckling parts 4 is used for tool to lock main part 1 to install on the frame of casement. A sliding block 5 is arranged in the mounting groove 3, and a clamping groove 501 which is convexly displayed outside the mounting groove is arranged on the sliding block 5. A limiting structure is arranged between the mounting groove 3 and the sliding block 5, and the sliding block 5 slides in the mounting groove 3 in a limiting mode. One end of the sliding block 5 is provided with a rebounding structure for the sliding block 5 to return automatically. The locking groove 501 is correspondingly matched with a locking bar for engaging and disengaging the safety grid.

As shown in figure 3, the limiting structure comprises a strip-shaped limiting hole 6 and a limiting block 7, the strip-shaped limiting hole 6 is formed in the side face of the mounting groove 3, the limiting block 7 is connected to the sliding block 5, and the free end of the limiting block 7 is matched in the strip-shaped limiting hole 6, so that the sliding block 5 is limited in sliding.

As shown in fig. 4 and 8, a limit lock 8 is disposed between the resilient structure and the engaging portion 4, and the limit lock 8 is used for limiting the stroke of the slider 5. The limit lock 8 may be any existing key lock, tool lock, combination lock, fingerprint lock, or any lock capable of achieving the above function, without limitation. The resilience structure comprises a spring 9 and an extension part 10, the extension part 10 is connected at the top of the end face of the sliding block 5, one end of the spring 9 is connected with a limiting lock 8, the other end of the spring is connected with the end face of the sliding block 5, and the spring 9 is located below the extension part 10. In the process of pushing the sliding block 5 to slide towards the direction of the limit lock 8, the sliding block 5 compresses the spring 9. When the position-limiting lock 8 is in an unrestrained state, that is, the stopper 801 of the position-limiting lock 8 is rotated to one side, the extension 10 is not blocked, and the spring 9 can be compressed to the maximum. In other words, the maximum moving distance of the stopper 7 from one end to the other end of the strip-shaped stopper hole 6, i.e., the maximum stroke of the slider 5. When the stop 801 of the position lock 8 is in the locked state, i.e. in the position to limit the movement of the extension 10, the slider 5 slides at most until the extension 10 collides with the stop 801, and can not slide any more. Due to the action of the spring 9, the slider 5 will automatically return to the initial position under the action of the spring force after the finger is released.

The finger pushes the slider 5 to slide, with the purpose of bringing the locking bar to slide. The locking bar is arranged in the frame of the window sash in a sliding way or is provided with a sliding groove in which the locking bar can freely slide to realize the locking and unlocking functions. The locking bar comprises a connecting piece 11 and a sliding piece 12, one end of the connecting piece 11 is matched with the clamping groove 501, the other end of the connecting piece 11 is vertically connected to one side face of the sliding piece 12, a locking point 13 is arranged on the other side face of the sliding piece 12, and the locking point 13 is used for buckling a locking hole 14 in the safety grid. While the upper end of the locking bar slider 12 is provided with an upper sliding lock mount 15. The connection of the connecting member 11, the locking point 13, and the upper slide lock holder 15 to the sliding member 12 may be fixed connection by welding or the like, or may be detachable connection as shown in fig. 6 and 7. The advantage of the detachable connection is that it is easy to replace, combine, assemble, maintain, etc. As shown in fig. 5, the detachably connected sliding member 12 may be provided in an i-shape or the like, and the cross-sectional shape thereof is not particularly limited. The slider 12 is provided with a threaded hole, and as shown in fig. 6 and 7, a base plate 16 is provided, and the base plate 16 is also provided with a threaded hole and fixed to the slider 12 by means of a screw. The connecting end of the same locking point 13 is connected to the base plate 16 and the slider 12 by means of a screw thread. The bottom plate 16 increases the thickness of the joint of the slider 12, so that the mounting of the locking point 13 is more secure.

The utility model discloses an operating principle does, under the not spacing circumstances of spacing lock 8, with the directional push slider 5 that pushes down of hand, slider 5 drives slider 12 and slides downwards through the connecting piece 11 of card holding in draw-in groove 501 to make it slide lock seat 15 and break away from going up, the casement can freely slide. When the sliding block 5 slides to the maximum stroke, the locking point 13 on the sliding part 12 can be separated from the locking hole 14, so that the separation of the safety grid and the window sash is realized, and the outdoor operation or the escape and the like are facilitated. After the operation is finished, the fingers are loosened, the sliding block 5 automatically returns under the action of the spring force, and the upper sliding lock seat 15 is contacted with the upper sliding, so that the window sash is locked in real time, and personnel can be prevented from pushing the window sash from the open air. When the limit lock 8 is in the locked state, i.e., the limit state, the stroke of the slider 5 is limited, for example, by half. Similarly, the sliding block 5 is pushed downwards by hand, so that the upper sliding lock seat 15 can be separated from the upper sliding, and the safety grid and the window sash can be moved simultaneously. And releasing the fingers, returning to the original position, and locking the window sash in real time to prevent the window sash from moving. Because the limit lock 8 is in a locking state, the safety lattice and the window sash cannot be separated, and only when the limit lock 8 is opened, the sliding block 5 can continuously slide downwards to separate the safety lattice. The same is true in the process of connecting the safety grid with the window sash, the limiting lock 8 is in an open state, the sliding block 5 is slid to the maximum travel position of the low end by fingers, the safety grid and the window sash are moved together, the locking point 13 can automatically correspond to the locking hole 14, then the fingers are released, and the sliding block 5 returns, so that the connection of the safety grid and the window sash is realized.

The utility model discloses simple structure, reasonable in design, the practicality is stronger, is provided with limit structure, resilience structure and spacing lock 8, under its mutually supporting, firstly can restrict the stroke of slider 5, secondly the stroke of adjustable slider 5, thirdly slider 5 can self return to realize the separation and reunion of locking strip and safety grid, and to the real-time locking of casement, the function is comprehensive, is suitable for popularization and application.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
