Description

Technical Field

[0001] The utility model relates to the field of bolts, in particular to a concealed bolt mechanical door bolt structure. Background Art

[0002] Generally, when there is not much traffic and the traffic flow is simple, single-leaf doors (single door leaf) are generally used for interior door installation. However, in most public places, double-leaf doors (two door leaves) are used as the main installation requirement when there is a large traffic flow and the traffic flow is flexible. In the building requirements and regulations of advanced countries or mature markets, the application of escape doors and escape door locks is necessary. Whether it is a single door or a double door, all of them need to be installed with escape doors and escape locks, and some escape doors and escape locks need to have additional fire protection + escape functions.

[0003] There are different actual product installation methods for the product installation and application of double-opening escape doors (one that is often opened is called the main door or primary door, and the one that is not often opened is called the secondary door or secondary door). In addition to installing escape locks on both escape doors (main door and secondary door), some construction units will choose to install hidden bolt-type door bolts as a substitute for the secondary door that is not often opened; but the secondary door installed with a hidden bolt basically no longer has an "escape function" because no matter it is a manual type or an automatic / semi-automatic type hidden bolt door bolt, the secondary door can only be opened manually or passively when the main door is opened.

[0004] The main function of the concealed bolt is that when the construction unit considers "expanding the traffic flow planning when necessary but not needed at other times", the secondary door of the double door will be replaced with a concealed bolt to replace the escape lock. On the one hand, it can retain the purpose of expanding the traffic flow when necessary; on the other hand, it is purely a cost consideration (the cost of the concealed bolt is much lower than that of the escape lock) or a very small consideration can reduce the access control and door control costs of the secondary door (because the manual concealed bolt can only be manually opened when the main door is open).

[0005] At present, during the production of traditional concealed bolts, due to their complex structures, the internal structures of semi-automatic concealed bolts and automatic concealed bolts are usually quite different. In the actual production process, components with different structures need to be produced, which will incur high production costs and is not convenient for material preparation. Utility Model Content

[0006] The utility model provides a concealed latch mechanical bolt structure, which solves the problem that in the actual production process, components with different structures need to be produced, thereby generating a large production cost and being inconvenient for material preparation.

[0011] The above technical solution is adopted: by pressing the button, the button pushes the sliding block, the sliding block pushes the transmission block, the transmission block drives the pushing plate to move, and when the pushing plate drives the hidden latch to move downward, the hidden latch is separated from the secondary door, so that the secondary door is in a state that can be opened. At this time, the tension spring arranged between the pushing plate and the screw positioning frame is in a stretched state, and then the tension spring contracts and drives the pushing plate to move upward. The pushing plate pushes the transmission block and the sliding block to reset, the sliding block pops out the button, and the hidden latch is engaged with the secondary door, so that the secondary door is in a fixed state.

[0012] Preferably, a button is movably inserted into the semi-automatic decorative panel and the fixing seat, and the button is fixedly connected to the sliding block.

[0013] The above technical solution is adopted: after the main door is opened, by pressing the button, the button can control the switch of the semi-automatic concealed bolt mechanical door bolt.

[0015] The above technical solution is adopted: by closing the main door, the lock tongue inside the automatic concealed bolt mechanical bolt is forced to move toward the inside of the mechanism box and squeeze the sliding block. The sliding block pushes the transmission block to rotate and move along the first fulcrum. The second fulcrum on the transmission block drives the push plate to move upward along the mechanism box and compresses the second compression spring, so that the push plate lifts the screw guide sleeve and the concealed bolt, and clamps the concealed bolt inside the secondary door to fix the secondary door. After that, the main door is opened, and the second compression spring extends to push the push plate downward. The push plate drives the screw guide sleeve and the concealed bolt to reset, so that the concealed bolt is separated from the secondary door, so that the secondary door can be opened.

[0016] Preferably, a lock tongue is movably inserted into the automatic decorative panel and the fixed seat, and the lock tongue is movably connected to the sliding block. By allowing the first fulcrum to be slidably connected to the sliding groove and the second fulcrum to be clamped with the inner groove, the first fulcrum cooperates with the second fulcrum, so that the lateral force exerted on the sliding block is transmitted to the push plate through the transmission block, and the push plate moves longitudinally.

[0017] By adopting the above technical solution: by opening the main door, the lock tongue automatically pops out, so that the secondary door can be opened; by closing the main door, the main door squeezes the lock tongue, so that the secondary door is closed.

[0018] Compared with the related art, the utility model has the following beneficial effects:

[0019] 1. Compared with the traditional concealed bolt, the utility model sets a mechanism box and a push plate.
