Abstract

The utility model discloses a device for securing the latch while bidirectional lock-bolt synchronous shooting, comprising a sliding lock-bolt control unit, a lock-bolt, an upper lock-bolt pull plate and a lower lock-bolt pull plate. The sliding lock-bolt control unit is provided with a lock-bolt releasing clamping mouth, and clamping feet corresponding to the lock-bolt releasing clamping mouth are arranged on the upper and the lower lock-bolt pull plates. The sliding lock-bolt control unit is linkedly connected with a sliding plate shifting block, and a lock-bolt ejection clamping mouth is arranged on the sliding plate shifting block, and a sliding plate clamping foot corresponding to the lock-bolt ejection clamping mouth is arranged on the sliding plate which is fixedly connected with the lock-bolt. For the device for securing the latch while bidirectional lock-bolt synchronous shooting, no matter a door is opened towards the left or the right, as well as inwardly or outwardly, the lock can enter into the sliding lock-bolt position when the door is closed, and a plurality of sets of (upper, lower and side) lock-bolts can be ejected outwardly, automatically and synchronously to the blocking state. While in use, the utility model is safe and reliable, and phenomenon of spurious lock cannot occur; in particular, the problems in the prior art are solved that spurious lock caused by non-targeting lock-bolt occurs when the sliding lock-bolt is pressed into the lock-bolt and the sliding lock-bolt can be ejected outwardly, accordingly, the safe lock is not safe.

Description

Two-way lock tongue synchronous spring out locking 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 lock tongue synchronous spring out locking device.

Technical background

At present the theftproof lock that ejects automatically of dead bolt all is a dead bolt place ejection state when sliding-tongue begins to advance at closing time, and this structural relation is not because dead bolt just is in the ejection state aiming at the duct, very easy dead bolt is damaged, and produces the false phenomenon of locking; Also have at sliding-tongue and the external increase dead bolt of dead bolt control device, can make the complex structure of lock like this, also increased cost.

The utility model content

The purpose of this utility model is that a kind of simple in structure, safe and reliable, two-way lock tongue synchronous spring out locking device of having only when sliding-tongue ejects dead bolt just to eject synchronously is provided for the deficiency that solves above-mentioned technology.

In order to achieve the above object, a kind of two-way lock tongue synchronous spring out locking device that the utility model is designed, it comprises sliding-tongue control module, dead bolt and upper and lower dead bolt arm-tie, the sliding-tongue control module is provided with dead bolt and discharges bayonet socket, upper and lower dead bolt arm-tie is provided with dead bolt and discharges the corresponding card base of bayonet socket, sliding-tongue control module and slide plate shifting block are connected, and the slide plate shifting block is provided with dead bolt and ejects bayonet socket, and the slide plate of fixedlying connected with dead bolt is provided with dead bolt and ejects the corresponding slide plate card base of bayonet socket.Described sliding-tongue control module can be mainly to be made up of bi-directional movable sliding-tongue and sliding-tongue connecting rod, and an end of sliding-tongue connecting rod is connected with the bi-directional movable sliding-tongue, and the other end penetrates in the fixing backstop plate hole, at the sliding-tongue connecting rod sleeve stage clip is arranged.The bi-directional movable sliding-tongue can be single tongue structure, also can be two tongue structures.Dead bolt discharges bayonet socket and can be located on the sliding-tongue connecting rod in the sliding-tongue control module.Also can be located on the bi-directional movable sliding-tongue.On upper and lower dead bolt arm-tie, can be provided with the arm-tie pushing pin, on the fixedly connected slide plate of dead bolt, be provided with the arm-tie that matches with the arm-tie pushing pin and promote groove.

The resulting a kind of two-way lock tongue synchronous spring out locking device of the utility model, lock body can be regardless of left and right opening door and introversion and extroversion opens the door, can enter the sliding-tongue position automatically at closing time, many group (upper and lower and side) dead bolts can outwards eject into blocking synchronously automatically, during use, safe and reliable, and can not produce false lock phenomenon.Particularly, solved and compressed into dead bolt when sliding-tongue in the prior art and occur dead bolt vacation lock not in place with regard to outside bullet, made the unsafe problem of safety lock.

The specific embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment, but following embodiment does not limit content of the present utility model.

Embodiment:

As shown in Figure 1, a kind of two-way lock tongue synchronous spring out locking device that present embodiment is described, it comprises sliding-tongue control module 17, dead bolt 15 and upper and lower dead bolt arm-tie 6, sliding-tongue control module 17 is provided with dead bolt and discharges bayonet socket 5, upper and lower dead bolt arm-tie 6 is provided with dead bolt and discharges the corresponding card base 7 of bayonet socket 5, sliding-tongue control module 17 is connected with slide plate shifting block 10, slide plate shifting block 10 is provided with dead bolt and ejects bayonet socket 11, and the slide plate 16 of fixedlying connected with dead bolt 15 is provided with dead bolt and ejects bayonet socket 11 corresponding slide plate card bases 12.As shown in Figure 1 and Figure 2, described sliding-tongue control module 17 mainly is made up of bi-directional movable sliding-tongue 1 and sliding-tongue connecting rod 4, and an end of sliding-tongue connecting rod 4 is connected with bi-directional movable sliding-tongue 1, and the other end penetrates in fixing backboard 9 holes, is with stage clip 8 outside sliding-tongue connecting rod 4.Sliding-tongue 1 can be two tongue structures as shown in Figure 2, also can be single tongue structure as shown in Figure 3, and dead bolt discharges bayonet socket 5 and can be located at as shown in Figure 4 on the sliding-tongue connecting rod 4 in the sliding-tongue control module 17.Also can be provided in a side of on the bi-directional movable sliding-tongue 1 as shown in Figure 1.For the dead bolt 15 that makes the side passes in and out synchronously with the upper and lower dead bolt, on upper and lower dead bolt arm-tie 6, be provided with arm-tie pushing pin 13, on the fixedly connected slide plate 16 of dead bolt, be provided with the arm-tie that matches with arm-tie pushing pin 13 and promote groove 14.
