Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
Referring to fig. 1-4, the present invention discloses a door frame assembly for cooperating with a latch bolt, which includes a door frame edge strip 10, a roller seat 20 and a roller 30. The door frame edge strip 10 is installed on a door frame, a slot position for the bolt 50 to enter is pre-opened on the door frame, and a lock hole 11 suitable for the bolt 50 to enter and exit is correspondingly formed in the door frame edge strip 10; the roller seat 20 is fixedly connected to the door frame edge strip 10, a seat hole 21 is formed in the roller seat 20, the seat hole 21 is aligned and matched with the lock hole 11, and the bolt 50 penetrates through the seat hole 21 and the lock hole 11 and enters the door frame to be locked; at least one side of the roller seat 20 is provided with a shaft groove 22, and the shaft groove 22 is used for accommodating a roller 30; the roller 30 is cylindrical and is rotatably arranged in the shaft groove 22; the shaft groove 22 is communicated with the seat hole 21, and the bolt 50 interacts with the roller 30 after entering the seat hole 21, so as to drive the roller 30 to rotate.
As can be seen from the above description, when the bolt 50 extends and retracts in the door frame, i.e. locking or unlocking is achieved, the bolt 50 moves in a translational manner and drives the roller 30 to rotate, so that rolling friction is generated between the bolt 50 and the roller 30.
In one embodiment, the roller seat 20 is provided with a shaft groove 22 on each side, a roller 30 is accommodated in each of the two shaft grooves 22, and the two shaft grooves 22 are symmetrically arranged relative to the seat hole 21. The effect of this arrangement is: after the bolt 50 enters the lock hole 11, both contact side surfaces generate sliding friction with the roller 30, so that the generated resistance is further reduced, and the bolt is a better implementation mode.
In a preferred embodiment, the end of the axial slot 22 is provided with a limit stop 23. Since the roller 30 is rotatable in the shaft groove 22 and the roller 30 needs to be fixed in the axial direction, i.e. cannot fall or fall off, at least the lower end of the shaft groove 22 needs to be provided with a limiting stopper 23 to support and limit the roller 30; further, a stopper 23 is provided at the upper end of the shaft groove 22, so that the roller 30 is not disengaged by vibration.
In a preferred embodiment, the roller seat 20 is further provided with a first bolt hole 24, and the roller seat 20 and the door frame edge strip 10 are fixedly connected through a mounting bolt 40. Specifically, the first bolt holes 24 are opened between the two shaft grooves 22, the number of the first bolt holes is 2, and the first bolt holes are respectively located at the upper part and the lower part of the roller seat 20, so that better fixed installation can be realized.
As a preferred embodiment, a counter lock hole 12 is further formed below the seat hole 21, and the counter lock hole 12 is long and is suitable for the counter bolt of the lock to enter and exit. This arrangement is suitable for locks with anti-latch bolts, and typically there are a plurality of anti-latch bolts below latch bolt 50 for a second pass to improve security and safety.
In a preferred embodiment, the door frame edge strip 10 has second bolt holes 13 formed in upper and lower portions thereof for fixing to a door frame, and the door frame edge strip 10 is fixedly connected to the door frame by bolts.
Through the detailed explanation of the above embodiments, it can be understood that, in the present invention, after the bolt 50 enters the lock hole 11, rolling friction is generated between the bolt 50 and the roller 30, compared with sliding friction in the prior art, the resistance generated between the bolt 50 and the door frame assembly is greatly reduced, and the surfaces of the bolt 50 and the door frame are effectively protected; in addition, because the resistance reduces, the load of lock body reduces correspondingly, has reduced the consumption of lock body, makes the economic nature stronger, has improved the reliability of tool to lock simultaneously, has prolonged its life.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
