Description

A mechanical lock mechanism for a push-pull door

(1) Technical field

The utility model relates to a lockset, in particular to a mechanical lock mechanism for a push-pull door.

(2) Background Technology

At present, the rotary doors on the market can be equipped with locks very conveniently, but the push-pull doors are not convenient to be equipped with traditional door locks due to the limitation of their movement form, and the traditional door locks are basically single bolts, which have limited security.

(3) Contents of the invention

In order to make up for the deficiencies of the prior art, the utility model provides a mechanical lock mechanism for a push-pull door with high safety.

The utility model is achieved through the following technical solutions:

A mechanical lock mechanism for a push-pull door, comprising a lock case 1 and a lock case 2, characterized in that: the lock case 1 is provided with an active handle and two driven bolts, and the active handle passes through the rotating shaft 1 and the transmission rod 1 It is connected with the sliding rod, and the outside of the sliding rod is provided with a limit block. The sliding rod is connected with the lock tongue through the transmission rod two. .

Therefore, the beneficial effect of the utility model is: the mechanical lock mechanism of the push-pull door can achieve the purpose of self-locking, and only needs to pull the handle when opening the door, and adopts double deadbolt structure, the force is symmetrical, and the performance is better. Good, high safety, extended service life, convenient and practical. the

(4) Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing 1 is the mechanism schematic diagram of the utility model;

Accompanying drawing 2 is the open state schematic diagram of the utility model lockset;

Accompanying drawing 3 is the three-dimensional structure schematic diagram of the present utility model;

Accompanying drawing 4 is the schematic diagram that the utility model is installed on the push-pull type door.

In the figure, 1 lock case 2, 2 deadbolt, 3 rotating shaft 2, 4 transmission rod 2, 5 limit block, 6 transmission rod 1, 7 rotating shaft 1, 8 active handle, 9 sliding rod, 10 lock housing 1, 11 Limit lever, 12 compression springs. the

(5) Specific implementation methods

Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a lock case one 10 and a lock case two 1, and is characterized in that: the lock case one 10 is provided with an active handle 8 and two driven bolts 2, and the active handle 8 passes through the rotating shaft one 7 and the transmission rod one 6 is connected with the sliding rod 9, the outside of the sliding rod 9 is provided with a limit block 5, the sliding rod 9 is connected with the dead bolt 2 through the transmission rod two 4, the dead bolt 2 is fixed with the rotating shaft two 3 and a limit rod 11 is provided for the direction of movement on one side, A compression spring 12 is installed between the two dead bolts 2 .

Adopt the mechanical lock mechanism of the push-pull door of the present utility model, be fixed with on the lock shell one 10 for the rotating shaft one 7 that the driving part and the follower rotate, the rotating shaft two 3 and a pair of limit blocks 5, one that play the position-limiting effect To limit bar 11, active handle 8 and main driving rod are made into one, and active handle 8 is positioned at lock housing one 10 outsides, and main driving rod is positioned at lock housing one 10 inside, when rotating active handle 8, drives the transmission that is hinged with it. Rod one 6, transmission one 6 drives the slide bar 9 that is connected with it, due to the effect of stop block 5, slide bar 9 does linear motion, drives transmission bar two 4 thereupon, and finally transmits motion force on the dead bolt 2, makes The dead bolt 2 rotates a certain angle around the rotating shaft 2 3 to buckle the lock groove in the lock housing 2 1 to achieve the purpose of locking. A compression spring 12 is installed in the middle, and the compression spring 12 is fixed by the short bar on the dead bolt 2, so that the two dead bolts 2 are always in the state of mutual opening. In order to avoid the excessive opening angle of the two dead bolts 2, a limit Position lever 11, when pushing the two doors to close together, the dead bolt 2 can be automatically retracted inwardly by the lock groove of the lock housing 21, and when the end of the stroke is reached, that is, the door is fully closed, due to the action of the spring 12, the dead bolt will 2. Fasten it in the lock slot; when the door needs to be opened, just turn the active handle 8 counterclockwise. Therefore, the beneficial effect of the utility model is: the mechanical lock mechanism of the push-pull door can achieve the purpose of self-locking, and only needs to pull the handle when opening the door, and adopts double deadbolt structure, the force is symmetrical, and the performance is better. Good, high safety, extended service life, convenient and practical. the
