Description

Adjustable fire door locks can be installed without pressing

This creation is about a fire door lock, especially a fire door lock that can be installed and adjusted without the need for a press.

According to the existing fire door lock, there is a type of fire door lock that is connected and equipped with two vertical rods (commonly known as the heaven and earth bolts) and one upper and lower lock bolts. This is called the world-style fire protection. The door lock, such as the Republic of China Patent Gazette No. M297398, "Heaven and Earth Fire Door Lock Structure", please refer to the first figure, which includes a main lock portion 10, a pressure pin 11, a first adapter 12, and a lower The pull rod 13 , the lower lock bolt 14 , the second adapter member 15 , the upper pull rod 16 and the upper lock bolt 17 , wherein the first lock portion 10 side is sequentially arranged to vertically connect the first adapter member 12 and the pull rod 13 and the lower locking bolt 14, the other side of the main locking portion 10 is sequentially arranged to the second adapter 15, the upper pull rod 16 and the upper locking bolt 17, and the main locking portion 10 is provided with a body 101, two The pivoting block 102, a resilient member 103, and a sliding block 104, the pivoting block 102 is preferably triangular, and the first corner of the pivoting block 102 is pivotally disposed on the base 101. The pivoting block The second corner of 102 is coupled to the pressure pin 11 , and the third corner of the pivot block 102 is used to push the sliding block 104 for longitudinal displacement. The two ends of the member 103 are respectively coupled to the third corner of each of the pivoting blocks 102. The sliding block 104 is slidably coupled to the base body 101 and has two ends, respectively coupled to the first adapter 12 and the second turn Connector 15.

Please refer to the second and third figures. The principle of operation of the conventional "sky-fired door lock structure" is to pivot the pivot block 102 by pressing the pressure pin 11 to pivot the pivot block 102. The block 102 can push the sliding block 104 up, and the sliding block 104 can pull up the pull rod 16 and the pull rod 13, so that the locking bolts 17 and the locking bolts 171 and 141 of the lower locking bolt 14 can be respectively retracted. In turn, the unlock function is implemented.

After the above-mentioned fire door lock is completed, it is usually checked and confirmed whether the action state and position of the pull rod 16 and the pull rod 13 are correct to ensure the normal operation of the upper and lower lock bolts 17, 14, but the slide block 104 is It is disposed on the seat body 101 of the main lock portion 10 and directly interlocked with the pressure bar 11. Therefore, the conventional "sky-type fire door lock structure" must first be installed with a relatively heavy pressure pin 11 to be able to pull the rod through the pressure pin 11. The inspection of the movement and position is inconvenient in the installation adjustment. In addition, if it is found that the position of the tie rod installation needs to be adjusted after inspection, the components such as the pressure clamp 11 and the main lock portion 10 must be removed and reassembled, which is time consuming. The work is obviously causing troubles for the construction workers. Therefore, how to improve the above-mentioned defects, that is, the technical difficulties that the creators of this case want to solve.

In view of the existing heaven-and-ground fire door locks, the action of each of the tie rods is only linked with the pressure bar, so the pressure bar must be installed before the test can be tested and confirmed, and the working time of the installation adjustment is increased and inconvenient, so the creation is The goal is to develop a fire door lock that greatly enhances the ease of installation adjustment.

In order to achieve the above purpose, the present invention provides a fire door lock that can be installed and adjusted without pressing, and includes: a fire door lock assembly, the fire door lock assembly is provided with a base and a door lock drive member, the door lock The driving member is movably disposed through the base; a latch housing, The first and second ends of the lock bolt housing are open; a latch mechanism is disposed in the bolt housing, and the latch mechanism is provided with a brake in the middle The mechanism and a locking bolt mechanism and a lower locking bolt mechanism respectively connected to the upper and lower sides of the braking mechanism, the braking mechanism comprises a base, a cover body and a sliding mechanism, and the cover body is combined with the base cover The sliding mechanism is disposed inside the space formed by the cover body and the base; an external door lock is respectively provided with a handle on both sides of the outer door lock and a rotating shaft coupled with the handle, the rotating shaft and the rotating shaft driving member Its shaft jack is inserted through the card.

The braking mechanism is disposed inside the bolt housing, instead of being disposed directly on the base of the fire door lock assembly, and the sliding mechanism of the brake mechanism is provided with a rotating shaft driving member, so that the bulk installation is not required to be installed first. Under the premise of the components such as the pressing mechanism, the installation position of the fire door lock is adjusted and confirmed, so that the creation can greatly improve the assembly convenience.
