Description

A kind of marine fireproof lock

Technical field

The present invention relates to door lock fields, and in particular to be a kind of marine fireproof lock.

Background technology

Door lock is exactly for locking the door the equipment to prevent other people from opening.There are many classification of door lock, in each occasion pair The requirement of door lock is different, and average family generally uses safe-guard door lock, safe and price relatively cheap；In some high-end fields Institute, privacy mechanism can use coded lock, Fingerprint Lock, and safety is very high, expensive；Many public arenas all employ glass Door, therefore can be than wide to glass door lock use.

Wherein, Fire-proof lock is mainly used for fire resistant doorsets, is divided into two major classes, and one kind is common Fire-proof lock, be mainly used for locking and Open fire resistant doorsets；It is another kind of (to be commonly called as special Fire-proof lock：Fire engine access lock), it is mainly used for escape truck escape, plays guarantee The effect of personnel safety.

Currently, for ship door lock application field, it cannot be opened after common door lock is heated, not meet fire protection requirement； Fireproofing door lock is complicated, and volume is larger, and appearance is poor；Although simple keeper meets fire protection requirement, but do not have the work(of lock Energy.

Invention content

In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of both simple in structure, beautiful and generous, user Just, and fire prevention, antitheft marine fireproof are locked.

To achieve the goals above, technical scheme is as follows：A kind of marine fireproof lock, including it is lock core, lock tongue, convex Take turns mechanism, attacker；The cam mechanism includes shaft, block, torsional spring；The lock core is located at outside, and one end is equipped with key hole, One end is connected with cam mechanism；The lock tongue is located inside, is the lock tongue that intermediate recess is open-ended cavity, the cavity of the lock tongue Interior to be equipped with the cam mechanism, the lock tongue connects lock core by cam mechanism；One end of the shaft and the centre bit of lock core Set connected, the other end is connected with the center of block, and the block is set to the external end of shaft, is constituted together with shaft One bascule, the bascule are connected by block with torsional spring, and the controllable bascule of a dynamics is constituted；The button Hand is the embedded attacker that intermediate recess is open-ended cavity.

Further, the attacker includes fixinig plate, articulated shaft, buckle, inner panel；The buckle is located at the cavity of attacker Interior, the buckle includes the first buckle, the second buckle, and the first buckle side within the cavity is horizontally set at the outer of door, Front end is inwardly projecting, and second buckle is connected with the second buckle by articulated shaft perpendicular to the first buckle, first buckle； The fixinig plate is located at the angle of the first buckle and the second buckle；The upper end of the inner panel is connected with the lower end of the second buckle.

Further, the inwardly projecting angle in the front end of first buckle is 0 ° -90 °；The cross section of the inner panel is long Degree is equal to the length of the second buckle, and the cross-sectional width of the inner panel is equal to the width of the second buckle.

Further, the fixinig plate is cuboid fixinig plate, and screw is additionally provided on the fixinig plate.

Preferably, the screw is octagonal side shape.

Further, the block is protruding shaft structure.

Further, the torsional spring is fixed by screws in the cavity of lock tongue.

Preferably, the screw is round end plus screw.

Further, the marine fireproof lock is the marine fireproof lock that all-metal material makes.

The advantage of the invention is that：(1) all-metal material makes, indeformable after being heated, and meets ship fire protection requirement；(2) detain The embedded design of hand getting, simple in structure, elegant shape are applied widely；(3) lock core is connect with lock tongue by cam mechanism, Has the requirement of door lock under the premise of meeting fire protection requirement；(4) self-jacking type lock tongue, it is easy to use.

Specific implementation mode

It elaborates below to the embodiment of the present invention, the present embodiment is carried out lower based on the technical solution of the present invention Implement, gives detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation Example.

Embodiment：In conjunction with Fig. 1, Fig. 2, Fig. 3, a kind of marine fireproof lock, including lock core 1, lock tongue 2, cam mechanism, attacker 3； Cam mechanism includes shaft 4, block 5, torsional spring 6.

Lock core 1 is located at outside, and one end is equipped with key hole, and corresponding with key, one end is connected with cam mechanism.

Lock tongue 2 is located inside, is the lock tongue 2 that intermediate recess is open-ended cavity, cam mechanism is equipped in the cavity of lock tongue 2, Lock tongue 2 connects lock core 1 by cam mechanism, is controlled to realize from the unlocking of key, lock core 1, cam mechanism to lock tongue 2.

One end of shaft 4 is connected with the center of lock core 1, and the other end is connected with the center of block 5；Block 5 has Body is a protruding shaft structure, is set to the external end of shaft 4, a bascule is constituted together with shaft 4；Bascule is logical It crosses block 5 with torsional spring 6 to be connected, constitutes one and 1 degree of rotation of lock core is controlled by torsional spring 6, further control 5 rotation direction of block, To realize the controllable bascule of the dynamics that lock tongue 2 is closed, wherein torsional spring 6 is fixed on lock by a round end plus screw In the cavity of tongue 2.

Attacker 3 is the attacker 3 that intermediate recess is open-ended cavity, including fixinig plate 7, articulated shaft 8, buckle, inner panel 11；Buckle In the cavity of attacker 3, including the first buckle 9, the second buckle 10, wherein 9 side within the cavity of the first buckle is laterally set Be placed in the outer of door 12, front end is inwardly projecting, and specific angle outstanding is 0 ° -90 °, the second buckle 10 perpendicular to the first buckle 9, And it is connected with the first buckle 9 by articulated shaft 8；The angle of first buckle 9 and the second buckle 10 is consolidated by cuboid fixinig plate 7 Calmly, octagonal side shape screw there are one being set on fixinig plate 7；The upper end of inner panel 11 is connected with the lower end of the second buckle 10, wherein inner panel 11 cross-section lengths are equal to the length of the second buckle 10, and the cross-sectional width of inner panel 11 is equal to the width of the second buckle 10；Institute It is simple in structure to state attacker 3, it is applied widely, by pull the first buckle 9, just can drive inner panel 11 rear shifting and lock tongue 2 it is interior Contracting is further completed to unlock；Also, embedded design is used, it is beautiful and generous.

In addition, the marine fireproof lock is made of all-metal material, and it is indeformable after being heated, it remains able to open, meet Ship fire protection requirement.

In conjunction with Fig. 4, Fig. 5, the operation logic of the present embodiment is：

When key is inserted into keyhole, torsion lock core 1, shaft 4 drives the rotation of block 5 to the end for withstanding 2 head of lock tongue, prevents The state that fire lock shows to lock cannot open lock at this point, detaining the first buckle 9；

When Fire-proof lock is the state that do not lock, there are space in block 5 and the end on 2 head of lock tongue, at this point, detaining the first button Plate 9, lock tongue 2 are movable to rear side, and lock is opened.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
