Description

Two-way automatic sliding-tongue device

Technical field

The utility model relates to a kind of safety device that is used for safe-guard door lock, particularly a kind of two-way automatic sliding-tongue device.

Technical background

Present Safety door lock, often comprise sliding-tongue and dead bolt two parts and eject latch members, its sliding-tongue is the single face squint often, like this, just make it at closing time that lock had Nei Guan, Wai Guan, a requirement that open on a left side, open on the right side of door, then in use, just need the door lock of different directions is selected in not fellow disciple's unlatching, make door lock very easy makeing mistakes when selecting to buy.In present Safety door lock, sliding-tongue just plays the effect of control insurance dead bolt in fact, and when shutting the door after you, dead bolt promptly ejects automatically, so unidirectional sliding-tongue can not satisfy the needs of safety door development, and sliding-tongue also should have more reliable assurance to the control of insuring dead bolt.

The utility model content

The purpose of this utility model is that a kind of branch that makes lock body be regardless of left and right opening door and interior outward opening door is provided for the deficiency that solves above-mentioned technology, and a kind of two-way automatic sliding-tongue device simple in structure, that can control the dead bolt ejection simultaneously.

In order to achieve the above object, a kind of two-way automatic sliding-tongue device that the utility model is designed, it comprises the bi-directional movable sliding-tongue, described bi-directional movable sliding-tongue is made up of two sliding-tongues, between two sliding-tongues, be provided with bi-directional movable sliding-tongue connecting rod, between sliding-tongue, sliding-tongue and bi-directional movable sliding-tongue connecting rod, connect by the sliding-tongue pin, the link of bi-directional movable sliding-tongue connecting rod and movable sliding-tongue can be curved, the other end of bi-directional movable sliding-tongue connecting rod penetrates in the fixing backstop plate hole, at bi-directional movable sliding-tongue connecting rod sleeve stage clip is arranged.Be provided with dead bolt and eject bayonet socket on the sliding-tongue device of two-way bi-directional movable sliding-tongue and bi-directional movable sliding-tongue connecting rod composition, the dead bolt here ejects bayonet socket and can be located on the movable sliding-tongue of sliding-tongue device, also can be located on the bi-directional movable sliding-tongue connecting rod of sliding-tongue device.

The resulting a kind of two-way automatic sliding-tongue device of the utility model, when at closing time, no matter lock is provided in a side of the left and right of door, or the opening to being inside and outside of door, as long as movable sliding-tongue collision doorframe, movable sliding-tongue can take in the lock, and when going into position, sliding-tongue hole, under the effect of stage clip, eject automatically, when sliding-tongue ejects automatically, can eject the ejection that bayonet socket is controlled other dead bolt by dead bolt.
