Description

Electric rolling door bottom beam is locked automatically

Technical field

Improvement the utility model relates to the lock structure used on shutter door, specifically a kind of electric rolling door bottom beam Automatic lock.

Background technique

Currently, electric rolling door has been widely used in a variety of fields such as retail shop, bank, garage, market, hospital, industrial enterprise Institute.In order to improve the anti-theft pick-proof performance of electric rolling door, the electric rolling door especially used in retail shop, bank is mostly filled There is the ground lock for matching effect with the component for being located at subsurface, electric rolling door is further closed, to prevent from shutter door Door is pried open under door.But locking this kind ofly synchronous with electric rolling door cannot cooperate automatically operation, after closing shutter door, It needs manually to lock ground；Before opening shutter door, it is necessary to first manually lock ground and open, then open shutter door again.It is this The ground of anti-theft pick-proof is locked, first is that structure is more complicated, at high cost, operation troubles is more, poor reliability；Second is that using cumbersome not side Just, when electric rolling door opens or closes, it is necessary to lock with being opened by manual engagement or lockked.Frequent occurrence：Someone forgets It closes ground latching after shutter door, forms security risk；Also someone forgets to lock just starting shutter door with opening, and leads to shut-off Door is mutually pullled with ground locking phase, so that electric rolling door or ground is locked damage, is caused economic loss.

Summary of the invention

The purpose of this utility model be in view of the above deficiencies, provide a kind of structure it is simple, it is at low cost, easy to use, locking Intensity is high, electric rolling door bottom beam reliable for operation is locked automatically.

Realizing the technical solution of the utility model aim is：This electric rolling door bottom beam is locked automatically, by length and shut-off Door is of same size and the outer beam of ∏ shape and inner beam of mutual make-up are constituted, feature be inner beam two sides top it is corresponding be provided with it is vertical Left pilot hole, middle pilot hole and the right pilot hole in direction, the lower part of the two sides Wai Liang be correspondingly provided be each passed through left pilot hole, The left locating rod of middle pilot hole and right pilot hole, middle locating rod and right locating rod；Bottom in inner beam is equipped with a left side along its length The inner end of locking bar and right locking bar, left locking bar and right locking bar has been respectively articulated with left connection board and right connection board, left connection board and right company The other end of fishplate bar and middle locating rod are articulated and connected, and the outer end of left locking bar and right locking bar can stretch out the both ends of inner beam respectively；Outside The top of beam is fixedly connected with the arc-shaped door piece connecting plate being flexibly connected with pieces of roll type door.

Up and down with better balance between outer beam and inner beam in order to make, inner beam two sides top correspondence is provided with perpendicular Histogram to middle pilot hole be located at the middle position of inner beam, left pilot hole and right pilot hole are respectively symmetrically located at middle pilot hole two sides The both ends of inner beam；The two sides Wai Liang lower part is correspondingly provided with the left positioning for being each passed through left pilot hole, middle pilot hole and right pilot hole Bar, middle locating rod and right locating rod.

In order to keep the side-to-side movement in inner beam of left locking bar and right locking bar flexible, reliable, stable, left locking bar is corresponded in inner beam The component that at least a pair of of guide roller, guide rod or guide plate etc. play guiding and positioning function is respectively equipped with the position of right locking bar.

Using the arc-shaped door piece connecting plate above outer beam when use, electric rolling door bottom beam is locked automatically and electric rolling door Nethermost door piece connection.At electric rolling door when opening position, inner beam is fallen by self weight distinguishes left locking bar and right locking bar In inner beam；Outer beam, which moves down, when shutdown position at electric rolling door drops to ground, behind inner beam contact ground makes left locking bar Inner beam both ends are stretched out respectively with right locking bar, are inserted into the doorframe lockhole that two sides doorframe is correspondingly arranged, to lock below electronic Shutter door；Open electric rolling door when, electric rolling door rising lifts outer beam, the middle locating rod on outer beam in middle pilot hole on It mentions, makes to lift in left connection board and right connection board, while driving the beam middle part movement respectively inwards of left locking bar and right locking bar, leave doorframe Lockhole enters inner beam, so that electric rolling door be made to open.

It is larger in electric rolling door width, when the length of corresponding inner beam and outer beam is longer, in order to enhance electric rolling door bottom Intensity, balance and the functional reliability that beam is locked automatically can also divide between the left pilot hole and right pilot hole of inner beam two sides It is not symmetrically arranged at least a pair of of enhancing pilot hole, the increasing for being each passed through enhancing pilot hole is correspondingly provided in the lower part of the two sides Wai Liang Strong fix bar.

There is preferable sealing when in order to close electric rolling door with ground, can also be equipped with sealing strip in the lower part of inner beam.

The raw material such as existing steel plate and universal machine components can be selected in the utility model, and are added using conventional technique Work production is easy to implement.Can effectively replace existing structure is complicated, at high cost, operation troubles is more, the various shutter doors of poor reliability Ground lock, and can automatic running synchronous with electric rolling door, have design uniqueness, structure it is simple, it is at low cost, light-weight, make With convenience, lock intensity high, reliable for operation, easy the advantages that promoting the use of, having a wide range of application.
