The fixed box is disposed on the door frame, and the lock box body is mounted on the fixed box via a connecting assembly. The lock box body includes a cylindrical lock body, and the lock body has an eccentric keyhole along the axial direction.
[0006] The connecting component is coaxially disposed at the bottom of the lock box body, the lock box body can rotate around its axis, and the lock box body can be fixed by the connecting component after rotation.
[0007] Furthermore, the fixing box is a rectangular box structure with one end open, and the door frame is provided with a clearance hole corresponding to the opening position of the fixing box. The lock box body extends into the fixing box through the clearance hole and the opening of the fixing box.
[0008] Furthermore, the fixing box is provided with stiffening plates, which are fixed to the door frame.
[0009] Furthermore, the stiffening plate is welded and fixed to the door frame.
[0010] Furthermore, the lock box body has a U-shaped cross-section.
[0011] Furthermore, the connecting assembly includes a bolt and a nut, the nut is fixed to the bottom of the fixing box, the axis of the nut coincides with the axis of the fixing box, and the fixing box and the locking box body are respectively provided with through holes coaxial with the nut;
[0012] The bolt is connected to the nut through a through hole.
[0013] Furthermore, the bottom of the lock box body is provided with a countersunk hole, the head of the bolt is disposed in the countersunk hole, and the end face of the bolt head is flush with the bottom surface of the lock box body.
[0014] Furthermore, the lock box body end face is provided with a coaxial retaining ring, the inner diameter of which is larger than the diameter of the clearance hole.
[0015] The beneficial effects of this utility model are:
[0016] The lock box body of this utility model has an adjustable lock hole position. When there is unevenness between the door leaf and the door frame or when the door leaf shakes when closed, the position of the lock box body can be adjusted to ensure that the lock hole and the bolt are aligned, thereby ensuring that the lock body can be used.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] See Figures 1-5 This utility model provides a technical solution:
[0025] Example:
[0026] like Figures 1-5As shown, an adjustable lock box for a door frame main lock includes a fixed box 1 and a lock box body 2. The fixed box 1 is disposed on the door frame 3, and the lock box body 2 is mounted on the fixed box 1 through a connecting component 6. The lock box body 2 includes a cylindrical lock body 4, and the lock body 4 has an eccentric keyhole 5 along the axial direction.
[0027] The connecting component 6 is coaxially disposed at the bottom of the lock box body 2. The lock box body 2 can rotate around its axis, and the lock box body 2 can be fixed by the connecting component 6 after rotation.
[0028] The fixing box 1 is a rectangular box structure with one end open. The door frame 3 is provided with a clearance hole corresponding to the opening position of the fixing box 1. The lock box body 2 extends into the fixing box 1 through the clearance hole and the opening of the fixing box 1.
[0029] The fixing box 1 is provided with a stiffening plate 11, which is fixed to the door frame 3.
[0030] The stiffening plate 11 is welded and fixed to the door frame 3.
[0031] like Figure 4 As shown, the lock box body 2 has a U-shaped cross-section. (In this way, the keyhole 5 does not pass through the lock box body 2, thus ensuring that the lock box body 2 can be connected to the fixing box 1 through its bottom surface and connecting component 6).
[0032] like Figure 4 As shown, the connecting component 6 includes a bolt 10 and a nut 9. The nut 9 is fixed to the bottom of the fixing box 1, and the axis of the nut 9 coincides with the axis of the fixing box 1. The fixing box 1 and the locking box body 2 are respectively provided with through holes coaxial with the nut 9.
[0033] The bolt 10 is connected to the nut 9 through a through hole.
[0034] The bottom of the lock box body 2 is provided with a countersunk hole 7, and the head of the bolt 10 is located in the countersunk hole 7. The end face of the head of the bolt 10 is flush with the inner bottom surface of the lock box body 2.
[0035] The lock box body 2 has a coaxial retaining ring 8 on its end face, and the inner diameter of the retaining ring 8 is larger than the diameter of the clearance hole.
[0036] Among them, 1. The inner diameter of the fixed box 1 is matched with the outer diameter of the lock box body 2, which in turn ensures that the lock box body 2 rotates only around the axis of the lock box body 2 when it rotates.
[0037] Working principle: As shown in the diagram, the keyhole 5 is located near the right side of the door frame 3. When there is a gap in the door leaf, first tighten the bolt 10 (until it disengages from the nut 9). At this time, the lock box body 2 can rotate relative to its axis. The lock box body 2 can then be adjusted according to the position of the door leaf latch. When adjusted to correspond with the position of the latch, the lock box body 2 is fixed to the nut 9 by the bolt 10, ensuring that the position of the lock box body 2 is fixed and the keyhole 5 corresponds to the position of the latch.
[0038] The lock box body of this utility model has an adjustable lock hole position. When there is unevenness between the door leaf and the door frame or when the door leaf shakes when closed, the position of the lock box body can be adjusted to ensure that the lock hole and the bolt are aligned, thereby ensuring that the lock body can be used.
[0039] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
