Detailed description of the invention

Referring to accompanying drawing, this utility model is further illustrated.

In the present embodiment, including base plate 3, cover plate 1, dead bolt 2 and locking mechanism, cover plate 1 offers the cavity for dead bolt 2 activity, known referring to Figure of description 2, cover plate 1 is overall to be arranged in " several " font, in the middle part of it, projection goes out above-mentioned cavity, and described dead bolt 2 is movably connected in cover plate 1, and namely dead bolt 2 is folded between base plate 3 and cover plate 1. Dead bolt 2 is provided with crotch 24, this crotch 24 is the bending part tilted in the middle part of dead bolt 2, transverse slat 13 it is fixed with in cover plate 1, this transverse slat 13 preferred is welded on cover plate 1, pass through said structure, only needing when assembling this latch to be hooked on crotch 24 by extension spring 22 one end, the other end is fixed on transverse slat 13, very simply, conveniently.

Dead bolt 2 is strip, and described dead bolt 2 is connected to the portion of holding 21 that pushes away, and described cover plate 1 is provided for push away the chute 15 moved in the portion of holding 21, described in push away the portion of holding 21 through chute 15, stretch out outside cover plate 1.

Described locking mechanism includes the lock slots 12 being opened on dead bolt 2, be plugged on cover plate 1 and with the button 6 of lock slots 12 clamping, the spring 5 that hold button 6 ejects; One end that described button 6 is in cover plate 1 is connected to fixture block 61, and the width of this fixture block 61 is more than lock slots 12 width, and described lock slots 12 is provided for fixture block 61 and inserts the hole, location 11 of clamping near one end of extension spring 22. With reference to Figure of description 2 and 3, button 6 snaps in cover plate 1 upper shed, and cover plate 1 is stretched out in the less one end of diameter. The lower end of button 6 has opening, wherein places a spring 5, and when pressing the button 6, button 6 extrusion spring 5, spring 5 is subject to the counteracting force of base plate 3, has the trend of button 6 upwards jack-up, and the lower end that button 6 is relatively large in diameter and lock slots 12 are conflicted. In this condition, pushing away portion of holding 21, dead bolt 2 can along lock slots 12 sliding motion. When button 6 moves to hole place, location in dead bolt 2 sliding tray, button 6 is under the active force of spring 5, and the lower end being relatively large in diameter snaps in locating slot. Under this state, dead bolt 2 is locked, it is impossible to motion. When artificial presses the button 6 from outside, spring 5 compresses, and the less one end of button 6 snaps in lock slots.Unlock, dead bolt 2 return motion state again. Now, extension spring 22 one end connected due to dead bolt 2 is fixed on cover plate 1 transverse slat 13, is subject to a restoring force, and extension spring 22 drives dead bolt 2, and dead bolt 2 is regained original position.

This utility model additionally provides further improvement project, and differing only in of such scheme: the outside (namely deviating from the side of extension spring 22) of described transverse slat 13 offers a breach 131, and extension spring 22 hooks and is located in this breach 131. Thus avoiding preventing extension spring 22 from producing to slide on transverse slat 13, the performance making latch is more stable. When latch is installed, first dead bolt 2 is positioned in cover plate 1, transverse slat 13 is welded on cover plate 1, then extension spring 22 two ends are hooked respectively on the breach 131 and dead bolt 2 crotch 24 of cover plate 1 transverse slat 13. Then button 6 is placed the less one end of diameter stretch out outside cover plate 1 through dead bolt 2 chute 15, be relatively large in diameter one end and be positioned in chute 15. Finally cover base plate 3, by welding or other modes, by base plate 3 and cover plate 1 compact siro spinning technology.

In the present embodiment, the connection of extension spring 22 is simple, it is easy to install. After being connected with cover plate 1 and dead bolt 2 respectively at extension spring 22 two ends, extension spring 22 is in stable condition, stable movement, will not eject in the process of motion or skew. Transverse slat openings at one side 132 is used for fixing extension spring 22, and the motion that openings at one side is extension spring 22 leaves certain space, it is ensured that extension spring 22 is unobstructed in motor process.

Cover plate 1, base plate 3, for fixing box bolt and the position of lock core mechanism, button 6, coordinate the action of lock core mechanism and locking mechanism. On base plate 3, circular hole 31 for being fixed on desired location by latch, and square hole 33 is for securing cover plate 1, and cylindrical protrusion snaps in spring 5, further the position of fixing spring 5 and button 6. Cover plate 1 upper locking groove 12 provides space to the up and down motion of button 6, and the chute 15 on cover plate 1 is that the slip pushing away the portion of holding 21 leaves space.

The present embodiment lock core mechanism is only made up of dead bolt 2 and extension spring 22 energy storage device, it does not have complicated operation principle so that latch open locking action is simple and reliable.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
