Abstract

The utility model relates to a simple machine, particularly a push type cylinder lock protection device. The utility model mainly solves the problem that an existing lock protection device has inconvenient usage and a protected lock can not be completely covered. An inserting plate is arranged under a case body; the inserting plate, the case body and a bottom plate are provided with circular holes having the same size and corresponding positions; one end of the inserting plate is connected to a handle controlled through spring action; the cylinder provided with a concave opening is threaded through the inserting plate provided with a slide way, and one end is fixed on the case body through a ball spring. The utility model has convenient use and good lock protection effect.

Description

Spring lock protection device

The utility model relates to simple and mechanical, especially a kind of pressing pellet shot from a slingshot lock-protector.

At present, existing several lock-protectors mostly use inconvenience, can not block the lock that needs protection fully, have stayed trouble and worry for users unit.

It is a kind of easy to use that order of the present utility model is to provide, and can block the pressing pellet shot from a slingshot lock-protector of the lock that needs protection fully.

The technical solution of the utility model: shell body underlying one plate, has identical, the corresponding circular hole in position of size on plate, shell body, the base plate, plate one termination has the handle that is subjected to spring pressure control, pellet shot from a slingshot with recess passes the plate of slideway, one end is fixed in base plate through marble spring, the other end is combined with marble sleeve, and marble sleeve is fixed in shell body.

Advantage of the present utility model: technology is simple, and is easy to use, and it is effective to protect lock.

Narrate the utility model embodiment in conjunction with the accompanying drawings.

Fig. 1 the utility model front view.

Fig. 2 the utility model vertical view.

Fig. 3 opens the key lateral view.

During enforcement, a termination of plate 2 pushes away handle 7, and pellet shot from a slingshot 4 can be selected three for use, and recess separately is different to the distance of plate 2.Behind two tapered ends of two circular holes alignings with base plate 3, shell body 1 during use lock-protector is fixed on the door-plate.When lock-protector was closed, plate 2 sheltered from the circular hole of base plate 3, shell body 1.When opening lock-protector, to open key 12 inserts in the pellet shot from a slingshot 4, push pellet shot from a slingshot 4, pellet shot from a slingshot 4 slides along marble sleeve 10, slide into plate 2 positions and horizontal alignment up to three recesses 5, the handle 9 of plate 2 makes the pellet shot from a slingshot recess do relative motion along pellet shot from a slingshot slideway 11 in horizontal slip on slide rail 13 under the effect of spring 6 at this moment, thereby the circular hole on circular hole on the plate and base plate, the shell body coincides, and opens lock-protector.When closing lock-protector, push away handle 7, plate 2 is resetted, pellet shot from a slingshot 4 is upspring under the effect of compression spring 8, and recess 5 leaves plate, and plate 2 resets motionless, base plate, and circular hole is blocked by plate heavily again on the shell body.Present embodiment is aimed at the door with two locks and the double-pore structure of design can be designed to be directed to a tapered end and the single hole structure that is provided with in addition, and the course of work is identical.

Claims
