Abstract

The utility model discloses a reinforcing lock head of a multipoint type escape door lock. The reinforcing lock head of the multipoint type escape door lock comprises a lock shell and a moving wheel which is in rotary connection with one side wall of the lock shell through a first rotating shaft, wherein a second rotating shaft is arranged on the other side wall of the lock shell, a spring bolt is hinged on the second rotating shaft, a moving shaft which is formed integrally is arranged at the tail end of the spring bolt, and the moving end of the moving wheel is arranged below the moving shaft. The bottom of the lock shell is in sliding connection with a sliding plate, a moving block is arranged below the moving wheel, and a clamping groove is correspondingly formed in the position, where the moving block is, of the sliding plate, and when the sliding plate slides along the bottom of the lock shell, the clamping groove pushes the moving block to move. Pulling rod connection plates are arranged on two end portions of the sliding plate. The connection plates at two ends of the sliding plate are respectively connected with a pulling rod at a lock head end of the door lock and a pulling rod at a sky pin/ground pin end of the door lock, when the sliding plate is pulled by the pulling rod of the lock head end of the door lock, the sliding plate drives the spring bolt and the sky pin/the ground pin to retract, locking points between a door leaf and a door frame are increased so as to increase locking force of the door leaf and improve capability of bearing impact of the door leaf, and the reinforcing lock head is safe and reliable in use, and enables an applied range of the escape door lock to be wide.

Description

A kind of reinforcement tapered end of multiple spot type escaping door lock

Technical field

The utility model relates to a kind of escaping door lock, relates in particular to a kind of reinforcement tapered end of multiple spot type escaping door lock.

Background technology

Escaping door lock be widely used in emergency exit, various public place passage the door on, escaping door lock of the prior art can only be realized 3 lockings at most, namely Zhong Bu dead bolt and header and bottom the setting the sky, sell; For some in particular cases, for example on the train of running at high speed, car door need bear very big pneumatic power; Perhaps for higher Men Eryan, because the ability that withstands shocks from a local body of locking point away from more is more poor, then the locking force of 3 lockings is also inadequate, can not satisfy a body to the requirement of locking force, thereby has certain potential safety hazard.Technical problem to be solved in the utility model is how to improve on the basis of existing escaping door lock, make the escaping door lock after the improvement can bear stronger impact, to play the effect that eliminates safe hidden trouble and to make the application of escaping door lock can be more extensive.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of reinforcement tapered end of multiple spot type escaping door lock.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of reinforcement tapered end of multiple spot type escaping door lock, comprise lock housing, be rotatably connected on thumb wheel on lock housing one sidewall by the rotating shaft I, another sidewall of described lock housing is provided with the rotating shaft II, be hinged with dead bolt on the rotating shaft II, the dead bolt end is provided with integrated shifting shaft, the struck side of described thumb wheel is positioned at described shifting shaft below, described lock housing basal sliding is connected with slide plate, described thumb wheel below is provided with shifting block, described slide plate is provided with draw-in groove in described shifting block place correspondence, described slide plate is during along the lock housing basal sliding, and described draw-in groove promotes described shifting block motion, and described slide plate both ends are provided with the pull bar junction plate.

The struck side of described thumb wheel is extended two driving levers of described thumb wheel end face, and described two driving levers lay respectively at the both sides of rotating shaft I.

The beneficial effects of the utility model are: the junction plate at slide plate of the present utility model two ends can be connected with day pull bar of pin/ground pin end with the tapered end pull bar of existing three point latch respectively, when slide plate under the drive of tapered end pull bar when pulled, thumb wheel rotates dead bolt of the present utility model and regains, simultaneously, my god, sell and also follow slide plate and move withdrawal, the door lock release.Reinforcement tapered end of the present utility model has increased the locking point between door leaf and the doorframe, thereby has increased the locking force of door leaf, improves the ability that door leaf withstands shocks, and can satisfy the instructions for use of door leaf in particular cases, improves safety.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is use state diagram of the present utility model;

Fig. 2 is internal construction schematic diagram of the present utility model;

Fig. 3 is that Fig. 2 splits schematic diagram;

Fig. 4 is the schematic diagram of the utility model dead bolt released state.

The specific embodiment

With reference to Fig. 1, reinforcement tapered end of the present utility model is installed at the use state diagram on 3 type escaping door locks of prior art.

With reference to Fig. 2, Fig. 3, the reinforcement tapered end of multiple spot type escaping door lock of the present utility model, comprise lock housing 1, be rotatably connected on thumb wheel 3 on lock housing 1 one sidewalls by rotating shaft 2, another sidewall of described lock housing 1 is provided with rotating shaft 6, be hinged with dead bolt 5 in the rotating shaft 6, dead bolt 5 ends are provided with integrated shifting shaft 51, the struck side of described thumb wheel 3 is positioned at described shifting shaft 51 belows, described lock housing 1 basal sliding is connected with slide plate 4, described thumb wheel 3 belows are provided with shifting block 32, described slide plate 4 is provided with draw-in groove 42 in described shifting block 32 place's correspondences, described slide plate 4 is during along lock housing 1 basal sliding, described draw-in groove 42 promotes described shifting block 32 motions, and described slide plate 4 both ends are provided with pull bar junction plate 41.

As preferred embodiment of the present utility model, the struck side of described thumb wheel 3 is extended two driving levers 31 of described thumb wheel end face, described two driving levers 31 lay respectively at the both sides of rotating shaft I 2, like this, reinforcement tapered end of the present utility model can be applicable between door lock and day pin simultaneously and between door lock and the ground pin, possess versatility.

When the utility model is used in combination with 3 type escaping door locks of prior art, the junction plate 41 at slide plate 4 two ends is connected with day pull bar 8 of pin/ground pin end with the pull bar 7 of existing door lock end respectively, when pressing down door lock pressing plate 9, with reference to Fig. 1, Fig. 4, slide plate 4 is subjected to pull bar 7 pullings of door lock end, and along lock housing 1 basal sliding, thereby make the draw-in groove 42 on the slide plate 4 promote shifting block 32 motions, drive thumb wheel 3 I 2 rotations around the shaft, the driving lever 31 on the thumb wheel 3 is stirred tongue switching axle 51, drives dead bolt 5 and rotates in the withdrawal lock housings 1, at this moment, slide plate 4 also spurs day pull bar 8 of pin/ground pin end, and sky pin/ground pin is regained, and finishes the unlatching of door lock.

Reinforcement tapered end of the present utility model can be as required be used with dissimilar escaping door lock, increases one or more locking points, thereby increases the locking force of door leaf, improves the ability that door leaf withstands shocks, and makes the range of application of escaping door lock wider.

The utility model versatility is good, practical reliable, can be widely used among the various escaping door locks.
