[0008] The front end of the locking tongue stopper and the end located on the outside is provided with an inclined surface, and the inclined surface can abut against the locking tongue to form a stop structure.

[0009] The long strip through hole is transversely arranged on the locking tongue stopper, and there are two long strip through holes which are symmetrically arranged in the horizontal direction.

[0010] Locking screws are arranged in the two long strip through holes, and correspondingly, two threaded holes are arranged in the locking tongue stopper installation groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model discloses an adjustable lock strike plate for a push-latch type escape door lock. The user can adjust the protruding position of the lock tongue stopper by moving the lock tongue stopper forward and backward to ensure that the lock tongue can be tightly against the lock tongue stopper to prevent the lock tongue from shaking and the door body from loosening when locked with the lock tongue stopper. The adjustable lock strike plate is very flexible in use and the adjustment operation is also very simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0018] like Figures 1 to 4 As shown, the adjustable strike plate for a push-bolt escape door lock provided in this embodiment includes a mounting base 1 and a bolt stopper 2. A bolt stopper mounting groove 3 is provided on the front of the mounting base 1, and the bolt stopper 2 is fixedly mounted in the bolt stopper mounting groove 3. A long strip through hole 5 is provided on the bolt stopper 2, and a locking device 6 is provided in the long strip through hole 5, and the bolt stopper 2 is fixed in the bolt stopper mounting groove 3 through the locking device. One side of the bolt stopper mounting groove 3 is an open end 4. When the locking device 6 is in a loose state, the bolt stopper 2 can slide in the bolt stopper mounting groove 3 toward the open end 4 and thereby adjust the gap between the bolt stopper 2 and the bolt 7.

[0019] As described above, the locking device 6 is a locking screw 61 , and the bolt stopper mounting groove 3 is provided with a threaded hole 31 that can cooperate with the locking screw 61 . The locking screw 61 passes through the long strip through hole 5 and is threadedly connected with the threaded hole 31 .

[0020] As described above, the mounting base 1 is provided with a mounting hole 11 , and the mounting base 1 can be fixedly mounted on the door leaf 8 by screws.

[0021] As described above, the front and outer end of the bolt stopper 2 is provided with an inclined surface 21, which can abut against the bolt 7 and form a stop structure. Such a structural design allows the bolt stopper 2 to better cooperate with the bolt 7. And by turning the handle 9 on the door leaf 8, the bolt 7 can be controlled to retract so that the bolt 7 and the bolt stopper 2 are in an unlocked state, and then the door leaf 8 can be opened.

[0022] As described above, the long strip through hole 5 is transversely arranged on the lock tongue stopper 2, and two long strip through holes 5 are arranged symmetrically in the horizontal direction. Such a structural design makes the lock tongue stopper 2 more stable when fixed in the lock tongue stopper installation groove 3, and can slide more smoothly when the locking screw 61 is in a loose state.

[0023] As described above, the two long strip through holes 5 are each provided with a locking screw 61 , and correspondingly, the bolt stopper installation groove 3 is provided with two threaded holes 31 .

[0024] In summary, when the clearance between the lock tongue 7 and the lock tongue stopper 2 needs to be adjusted, the user can loosen the locking screw 61 and then move the position of the lock tongue stopper 2 to adjust the protruding position of the lock tongue stopper 2, ensuring that the lock tongue 7 can be tightly against the lock tongue stopper 2, so as to prevent the lock tongue 7 from shaking and the door body from loosening when locked with the lock tongue stopper 2. In addition, the adjustable lock plate is very flexible in use, and the adjustment operation is also very simple.

[0025] The above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
