[ detailed description ] embodiments

The invention relates to a universal door bolt, as shown in figures 1 to 7, comprising a main body 1, a locking plate 2 and a locking plate return spring 3, wherein:

the main body 1 comprises a sheet-shaped clamp plate 11 clamped at a door gap between the door frame 4 and the door 5, and a pair of hanging lugs 12 positioned at the front end of the clamp plate 11; the splint 11 is provided with a latch bolt access hole 111 for a latch bolt of a door lock to slide in at a position between the pair of hangers 12, and a locking plate hole 112 for the locking plate 2 to swing in and out is arranged at the middle position; when in use, the latch can be positioned by hooking the pair of hangers 12 in the latch sliding holes 41 of the doorframe 4;

the lock plate 2 is connected to the rear end of the main body 1 in a swinging manner, and under the action of the lock plate reset spring 3, the top door 21 at the front end of the lock plate 2 is obliquely exposed out of the lock plate hole 112 after being reset in a swinging manner; the top door position 21 of the locking tab 2 and the suspension loop 12 are located on each side of the clamping plate 11 (i.e. they are on different sides of the clamping plate).

When the invention is used, as shown in fig. 5, a pair of hanging lugs 12 of the bolt are hooked in the latch bolt sliding hole 41 of the doorframe 4, and at the moment, the top door position 21 of the locking piece 2 is positioned at the side close to the door; when the door is closed, the door 5 touches the top door 21 of the lock plate 2, so that the lock plate 2 swings into the lock plate hole 112 of the clamping plate 11 after overcoming the acting force of the lock plate reset spring 3, and the door can be closed; once the door 5 is closed, when the outer end of the latch bolt of the lock slides into the latch bolt sliding hole 41 of the door frame 4 from the latch bolt access hole 111 of the clamping plate 11, the locking plate 2 swings to reset under the action of the locking plate resetting spring 3, so that the top door 21 is exposed out of the locking plate hole 112 again and is obliquely propped on the inner surface of the door, and thus, the door can be prevented from being pushed open by an illegal person outside the door, and the purposes of door bolting and burglary prevention can be achieved. When the door is opened, the door can be opened only by swinging the locking plate 2 into the locking plate hole 112 after overcoming the acting force of the locking plate reset spring 3, and then the door bolt is taken out. It can be seen from the above that, because the structure of the keeper is simple, the keeper can be carried around for use when going out at any time, so that when a user needs to lock a door, the keeper can be used by hooking a pair of lugs 12 of the keeper in the latch bolt sliding holes 41 of the door frame 4; and because the clamping plate 11 and the hanging lug 12 are in a sheet shape, the door bolt can be used by utilizing a door gap between the door and the door frame and the gap allowance (the upper and lower rest positions except the oblique bolt) of the oblique bolt sliding hole on the door frame as long as the door with the door lock is installed, so that the door bolt is reasonable in structure and convenient to use, is suitable for all doors with door locks, and achieves the effect of a universal door bolt.

In order to facilitate carrying and make the bolt look more beautiful, the first and second embodiments are better implemented by making the bolt into a box shape, as shown in fig. 1 and 6, the box can be square, round, etc. For this purpose, a box body 6 is fixedly sleeved at the tail end of the main body 1; a button 7 which can act on the tail end of the locking plate 2 to make the locking plate 2 swing to the locking plate hole 112 of the clamping plate 11 is arranged on the box body 6; the front end of the main body 1 is sleeved with a box cover 8 which is buckled with the box body 6 (positioned by an elastic sheet or a convex point or a concave position) or screwed (in an inner thread mode or an outer thread mode). The box of the universal door bolt can be square, round, oval and the like, and when the box is round, the box body and the box cover can be screwed together in a screwing mode.

In order to better mount the main body on the door frame, in the first and second embodiments, the clamping plate 11 is provided with a magnet placing hole 113 for installing a magnet (not shown) at a position between the latch access hole 111 and the locking plate hole 112, so that the main body is attracted to the metal striker 9 of the door frame 4 by the magnet. In the present embodiment, there are two magnet placing holes 113 to place the magnets, respectively.

The lugs 12 are perpendicular to the clamping plate 11, and in the first and second embodiments, the main body 1 is formed by stamping, so that when a pair of lugs are formed by stamping, the latch bolt access hole 111 is formed by the way, thereby greatly reducing the production cost.

In the first and second embodiments, the locking plate return spring 3 is a torsion spring, and the torsion sleeve hole 31 at the middle part thereof is sleeved on the swing shaft 22 of the locking plate 2, and the stressed parts at the rear two ends are respectively contacted with the clamping plate 11 and the locking plate 2. Of course, the locking plate return spring 3 may be a tension spring, a compression spring, or the like, as long as the locking plate can swing outward and the top door is exposed obliquely.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made herein without departing from the principles and spirit of the invention as defined by the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the remainder of the disclosure, but rather to limit the scope of the disclosure to the full extent set forth in the appended claims.
