Abstract

The utility model relates to a folding door supplementary lock a door mechanism, especially a locking mechanism between folding every. This mechanism is in the binding face top of closing relatively of two folding door leafs do not be equipped with a set of lug of mutually supporting and recess, the cooperation of lug and recess the time initial contact position be located door leaf opposite face moving trajectory, the lug embedding was in the recess when opposite face laminating was opened in the folding door fanning. The utility model discloses door body upper portion when closing the folding door carry on auxiliary fixed, the reinforcing door body to the holding capacity of external force, avoid it to lead to the fact switch men buchang's the circumstances because of external force takes place deformation in, realize supplementary locking through agreeing with of physical arrangement, avoided because of losing the problem that electric power lost efficacy, it is not enough that the while has avoided also that the circuit that connecting wire led to the fact easily decreases, on the other hand does not set up additional mechanism at the positive and negative of door leaf when this locking mechanism is closed, and parts are small and exquisite in addition, do not influence the whole outward appearance of door leaf.

Description

Lockable mechanism between a kind of folding every

Technical field

This utility model relates to a kind of folding door auxiliary lock door mechanism, lockable mechanism between especially a kind of folding every.

Background technology

Vertical hinged door is the one of garden door, and its structure is with on cavity or column by hinged to a fan or multiple leaf door body, realizes switch gate by the rotation of door leaf.In vertical hinged door, there is a kind of expansion relative by two Folding wings and fold and form the split folding door closed the door and open the door, this type of folding door in off position, is normally only provided with in bottom and fastens with a bolt or latch slottingly, owing to vertical hinged door has certain height, after bottom locks with bottom surface, Hen Chang one end, top distance is in free state, it is possible to readily promoted, and after long-term promotion, door leaf is susceptible to deformation, affect the normal of door leaf launch and fold, cause switch gate obstacle.

In order to solve this problem, existing folding door typically installs an electromagnetic attraction lock in the middle and upper part of door leaf, and the ground breech lock removing bottom stops mode, and by electromagnetic attraction as closing the principal organ of gate control, this kind of mode exists following several problem:

1, electromagnetic force lock electromagnetic adsorption and release be all by electric power signal control and electromagnetic action, if once there is the situation of power-off, then electromagnetic attraction lock lose door leaf latch functions, door leaf be in can free switch state, there is potential safety hazard；

2, electromagnetic attraction lock needs to connect external control device by electric wire in use, and barish electric wire is exposed in natural environment for a long time, and after Exposure to Sunlight, rain erosion etc. act on, circuit is as easy as rolling off a log aging；

3 and when folding door works, door body folding stretching repeatedly followed the most accordingly by electric wire, has further speeded up the aging of electric wire, so there is also potential safety hazard in electric connection mode；

4, electromagnetic attraction lock is installed on inner side or the outside of door leaf as attachment device, owing to it needs to produce electromagnetic action, so its internal building block is more, so its volume is relatively large, it is installed on outside door body, causes door body surface texture lofty, affect the outward appearance of door body.

Utility model content

In order to solve above-mentioned technical problem, lockable mechanism between the folding every of the locking that a kind of auxiliary of this utility model offer carries out door leaf top.

To achieve these goals, this utility model adopts the following technical scheme that

This mechanism includes two Folding wings that can relatively launch and draw in, fasten with a bolt or latch with being provided with bottom Folding wing, it is improved by: the relatively closed binding face top of two described Folding wings is respectively equipped with one group of projection cooperated and groove, the initial contact location during cooperation of described projection and groove is positioned on door leaf opposite face running orbit, and when Folding wing launches opposite face laminating, projection embeds in a groove.

Preferably, described projection is a trapezoidal taper type structure；Described groove is a trapezoidal frustum connected in star.

Preferably, edges and corners, the side rounding of described projection.

Owing to have employed said structure, of the present utility model a kind of fold that the lockable mechanism door body top when closing folding door between every assists fixing, strengthen door body to the holding capacity of external force, avoid it to deform upon the situation causing switch gate the most smooth because of external force while, realize assisting locking by agreeing with of physical arrangement, driven by power is need not during locking, avoid the problem lost efficacy because losing electric power, it also avoid the deficiency connecting the circuit rapid wear that electric wire is caused simultaneously；On the other hand, during this lockable mechanism Guan Bi, acting surface binding face between door leaf, the positive and negative at door leaf does not arranges additional mechanism providing additional operation, and parts are small and exquisite, does not affect the overall appearance of door leaf.

Detailed description of the invention

As shown in figures 1 and 3, embodiment of the present utility model a kind of folds lockable mechanism between every and includes two Folding wings 1 that can relatively launch and draw in, 2 are fastened with a bolt or latch with being provided with bottom Folding wing 1, relatively closed binding face 11 and 12 top of two described Folding wings 1 is respectively equipped with one group of projection cooperated 3 and groove 4, the initial contact location during cooperation of described projection 3 and groove 4 is positioned on door leaf opposite face running orbit, and when Folding wing 1 launches opposite face laminating, projection 3 is embedded in groove 4.

Said mechanism is according to the running orbit of the opposite face of Folding wing, the projection 3 matched and groove 4 are set on the top of Folding wing 1, it is fixing that door body top when closing folding door assists, strengthen the door body holding capacity to external force, it is to avoid it deforms upon the situation causing switch gate the most smooth because of external force.

Wherein, as shown in Figure 3 and Figure 4, the initial contact location during cooperation of described projection 3 and groove 4 is positioned on door leaf opposite face running orbit and refers to, before door leaf arrives last fit-state with desired trajectory relative motion, projection 3 contacts in advance with groove 4 and enters, along with the further laminating of door leaf opposite face, and projection 3 being embedded in groove 4 progressively, after treating that door leaf opposite face is fitted completely, projection 3 is completely embedded in groove 4.As it is shown in figure 5, when door leaf completely closes, projection 3 and groove 4 are hidden in two binding faces of door leaf 1, auxiliary locking structure does not exposes, and keeps harmony and the concordance of door body outward appearance.

Projection 3 in the present embodiment and groove 4 are only used as the retaining mechanism of auxiliary and use, main close door lock the most still use bottom ground door bolt.

Abjection during for the ease of coordinating and opening the door, in the present embodiment, described projection 3 is a trapezoidal taper type structure；Described groove 4 is a trapezoidal frustum connected in star.

In the present embodiment, edges and corners, the side rounding of described projection.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
