Abstract

The utility model discloses an electric rolling shutter door auto lock comprising an electric lock which is composed of a lock hook plate and a lock body, wherein the lock hook plate is provided with a lock groove, and the lock body consists of an external locking plate, an electromagnet, a locking cam and a locking box; an inclined plane is arranged at the front end of the lock hook plate which is matched with the locking cam of the electric lock and can be installed on the lower end beam of the rolling shutter door; and the included angle between the inclined plane of the lock hook plate of the auto lock and the bottom plane thereof is 5 degrees to 45 degrees. As for the electric rolling shutter door auto lock, even under the condition of power failure, when the door is locked, the inclined plane of the lock hook plate automatically locks the locking cam in the process that the lower end beam of the rolling shutter door drives the lock hook plate to move downwards; and when the lock groove on the lock hook plate reaches the position of the locking cam, the locking cam automatically pops up and is inserted in the lock groove of the lock hook plate, thus automatically completing the action of locking the door. The electric rolling shutter door auto lock not only has the advantage that the locking cam thereof can be automatically inserted in the lock groove of the lock hook plate even under the condition of power failure to complete the action of locking the door, but also has the advantages of simple structure and convenient use.

Description

A kind of electric rolling door automatic locking

Technical field

The utility model relates to a kind of electric rolling door automatic locking, belongs to electric rolling door lock technology field.

Background technology

At present, the lock crook plate of electric rolling door lock of the prior art generally all adopts straight tube shape or linkage type snap close, the greatest problem that the electric rolling door of these structures is latched in is: when closing rolling door, must switch on to electric lock, the tapered end of electric lock could be injected in the locked groove, thereby finish the action of locking a door of electric rolling door lock; If in a single day have a power failure when locking a door, the tapered end of electric lock can not inject in the locked groove, at this moment the lock box cover of electric lock must be opened, and promote tapered end by artificial mode, the tapered end of electric lock could be injected in the locked groove and finish the action of locking a door.If under situation about having a power failure, when locking a door, moving tapered end as the people who locks a door forgets after sending a telegram here again, because tapered end is stuck, when opening the door, is easy to burn the electromagnet of electric lock, causes and door can not be opened.Therefore the result of use of existing electric rolling door lock still is not ideal enough.

The utility model content

The purpose of this utility model is, though provide a kind of simple in structure, easy to use and when having a power failure its tapered end also can inject electric rolling door automatic locking in the lock crook plate automatically, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: electric rolling door automatic locking of the present utility model comprises by the lock crook plate that has locked groove with by exterior lock plate, electromagnet, tapered end and lock box forms the electric lock that lock body constitutes, and the front end of the lock crook plate on the bottom end rail that uses and can be installed in rolling door that matches with the tapered end of electric lock is provided with the inclined-plane.

The angle of the inclined-plane of lock crook plate and the angle of its baseplane is 5～45 degree.

Lock crook plate is fixed on the two ends of bottom end rail respectively by the stopper plate, and also is separately positioned on by the electric lock that electromagnet, tapered end and lock box are formed by the roller shutter gateway groove bottom at bottom end rail two ends.

On electromagnet, be provided with contact-making switch.

Owing to adopted technique scheme, the utility model is by having designed an inclined-plane on the lock crook plate on the bottom end rail that uses and can be installed in rolling door that matches with the tapered end of electric lock, even therefore under situation about having a power failure, when locking a door, drive in the process that lock crook plate moves down at the bottom end rail of rolling door, inclined-plane on the lock crook plate will compress tapered end automatically, reach the position of tapered end when the locked groove on the lock crook plate after, tapered end is under the effect of its spring force, can eject automatically and inject in the locked groove of lock crook plate, thereby finish the action of locking a door automatically.So the utility model is compared with prior art, the utility model not only have can be when having a power failure its tapered end also can inject automatically in the locked groove of lock crook plate and finish the advantage of action of locking a door automatically, but also have advantage simple in structure, easy to use.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of lock crook plate of the present utility model when being installed in the bottom end rail two ends of rolling door.

The specific embodiment

Embodiment of the present utility model: structure of the present utility model such as Fig. 1, shown in Figure 2, by exterior lock plate 3, electromagnet 4, the electric lock that tapered end 5 and lock box 6 are formed lock body can be made by traditional approach, during making, the front end of the lock crook plate that has locked groove 2 on the bottom end rail 1 that uses and can be installed in rolling door that matches with the tapered end 5 of electric lock is made an inclined-plane, the angle of the angle a of the inclined-plane of lock crook plate 2 and its baseplane is controlled at the scopes of 5～45 degree, and lock crook plate 2 is fixed on the two ends of bottom end rail 1, for easy to use, on the two ends of the bottom end rail 1 that is fixed with lock crook plate 2, weld a stopper plate 8 respectively, will be by exterior lock plate 3, electromagnet 4, the lock body that tapered end 5 and lock box 6 are formed is arranged on roller shutter gateway groove 9 bottoms; For control is convenient in use, on electromagnet 4, install contact-making switch 7.

When using the utility model, under the situation that electricity is normally being arranged, close the door lock a door in, press the pass door switch of rolling door, tapered end 5 actions, rolling door descends along roller shutter gateway groove 3, and descends together by bottom end rail 1 drive lock crook plate 2, when bottom end rail 1 arrived the lower end of roller shutter gateway groove 9, tapered end 5 injected in the locked groove of lock crook plate 2 automatically; When opening the door, press the door open switch of rolling door, at this moment electromagnet 4 drives tapered ends 5 actions, and tapered end 5 action backs contacts with contact-making switch 7, rolling door electrical power and drive the rolling door rising like this, thereby realization opening door operation.

When power failure need be locked a door, by rolling door is moved downward, in the process that its bottom end rail 1 drive lock crook plate 2 moves down, inclined-plane on the lock crook plate 2 will compress tapered end 5 automatically, arrive the position of tapered end 5 when the locked groove on the lock crook plate 2 after, tapered end 5 is under the effect of its spring force, and meeting is ejected automatically and injected in the locked groove of lock crook plate 2, thereby finishes the action of locking a door automatically.
