[0035] In the embodiment of the present disclosure, refer to Figures 1 to 8 as shown
[0036] A set of limit structures 4 is installed between the keyhole panel 1 and the bottom plate 2. The limit structure 4 is jointly composed of a first stabilizing plate 401, a welding block 402 and a limit plate 403. The first stabilizing plate 401 is provided with a rectangular welding block 402 at the upper position, and a limit plate 403 is welded at the upper position of the welding block 402. The material of the limit plate 403 is first the current metal wear-resistant material. After welding, the limit plate 403 and the first stabilizing plate 401 form an integral structure. The limit plate 403 is provided with a rounded corner at the upper position, and the rounded corner plays a role in guiding the movement of the lock tongue. After adjusting the limit plate 403 to the position corresponding to the side of the lock tongue, the first stabilizing plate 401, the welding block 402 and the limit plate 403 cooperate with each other to laterally limit the lock tongue, solving the problem that there is a gap between the current lock tongue and the keyhole panel 1, and it is easy to shake after the door body is closed. By installing the limit structure 4, the problem that the door body is easy to shake after being closed is solved;
[0037] In the embodiment of the present disclosure, refer to Figures 1 to 8 as shown
[0038] Two locking bolts 5 are installed between the threaded connection blocks 3 and the first stabilizing plate 401. A threaded hole is opened at the middle position of the threaded connection blocks 3, and a stepped adjustment hole is respectively opened at both sides of the first stabilizing plate 401. The locking bolts 5 pass through the interior of the adjustment holes and are connected to the threaded holes of the threaded connection blocks 3. The diameter of the adjustment holes is larger than the diameter of the locking bolts 5. Therefore, the first stabilizing plate 401 can be effectively adjusted in the left and right angles, and in addition, the first stabilizing plate 401 can be adjusted laterally in cooperation with the adjustment holes;
[0039] In the embodiment of the present disclosure, refer to Figures 1 to 8 as shown
[0040] A set of adjusting mechanism 6 is installed between the keyhole panel 1 and the first stabilizing plate 401. The adjusting mechanism 6 is jointly composed of a second stabilizing plate 601, a rotating plate 602, and an eccentric point 603. The rotating plate 602 is provided with an eccentric point 603 in the upper position. The eccentric point 603 is close to the edge of the rotating plate 602 and far from the center of the rotating plate 602. A threaded hole is opened at the eccentric point 603. A rotating hole is opened at the middle position of the first stabilizing plate 401. The adjusting bolt 7 passes through the welding of the rotating hole and the eccentric point 603. With the cooperation of the adjusting bolt 7, the effect of firmly connecting the eccentric point 603 and the first stabilizing plate 401 is achieved. An adjusting bolt 7 is installed between the first stabilizing plate 401 and the eccentric point 603. The second stabilizing plate 601 is installed inside the sliding groove of the bottom plate 2. The sliding groove realizes the effect of stabilizing the second stabilizing plate 601 up and down. The second stabilizing plate 601 stably moves horizontally in cooperation with the sliding groove. The second stabilizing plate 601 is provided with a rotating plate 602 in the upper position. The second stabilizing plate 601 and the rotating plate 602 are respectively of a cylindrical structure. Turning the adjusting bolt 7 with a screwdriver drives the adjusting mechanism 6 to rotate. Since the adjusting bolt 7 is welded to the eccentric point 603, when rotating, a part of the rotating plate 602 abuts against the inner wall of the profile, driving the limiting structure 4 to deflect in the opposite direction, realizing the effect of adjusting the angle of the limiting plate 403, so that the limiting plate 403 can be precisely adjusted according to the deviation of the lock tongue.
[0041] Embodiment 2, on the basis of Embodiment 1, referring to Figures 1 to 8 As shown, it is necessary to reserve an installation groove corresponding to the lock body on the door frame, and install the bottom plate 2 in the installation groove of the door frame firmly and hiddenly.
[0042] Embodiment 3, on the basis of Embodiment 1, referring to Figures 1 to 8 As shown, it is necessary to install a lock body corresponding to the keyhole panel 1 on the door leaf.
[0043] The working principle of this embodiment:
[0044] When installing the limiting structure 4, first install a threaded connection block 3 inside the bottom plate 2, then install the second stabilizing plate 601 and the rotating plate 602 in cooperation inside the bottom plate 2, install another threaded connection block 3 inside the bottom plate 2, and then install the first stabilizing plate 401 above the threaded connection block 3 and the rotating plate 602. Install the locking bolt 5 between the threaded connection block 3 and the first stabilizing plate 401, and install the adjusting bolt 7 between the first stabilizing plate 401 and the rotating plate 602. At this time, the limiting structure 4 and the adjusting mechanism 6 are mutually positioned. Install the keyhole panel 1 on the outside of the bottom plate 2 firmly with bolts, and then install the bottom plate 2 inside the door frame to complete the installation of the limiting structure 4;
[0045] When using the limit structure 4, adjust the limit plate 403 according to the lock tongue, loosen the locking bolt 5, then fasten the adjusting bolt 7 and the second stabilizing plate 6012. Rotate the adjusting bolt 7 with a screwdriver. At this time, the adjusting mechanism 6 will rotate inside the bottom plate 2. Driven by the eccentric point, the adjusting mechanism 6 drives the limit plate 403 to swing under force, completing the angle adjustment of the first stabilizing plate 401 and the limit plate 403. In addition, laterally adjust the limit plate 403 in cooperation with the adjustment hole of the first stabilizing plate 401 so that the side surface of the limit plate 403 corresponds to that of the lock tongue. Then fasten the locking bolt 5 to complete the position locking of the limit plate 403. After the door body is closed, the lock tongue moves to the position of the limit plate 403. When the door body is closed, the side surface of the lock tongue contacts the limit plate 403, and the limit plate 403 laterally limits the lock tongue.
