[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-2 and Figure 5 As shown, the utility model provides a door lock mounting sleeve body, comprising: a door panel 2 with at least two mounting holes 3 extending therethrough, wherein each mounting hole 3 is sequentially installed with a screw column 4, a mounting sleeve body 13 and a connecting screw 11 from the outside to the inside, and an end of the screw column 4 close to the mounting sleeve body 13 is provided with a connecting column 6 with a quadrilateral cross-section, and an insertion hole 14 for accommodating the connection column 6 is provided at one end of the mounting sleeve body 13, and a clamping piece engaged with the mounting sleeve body 13 is installed on the screw column 4.

[0025] As mentioned above, when using the door panel 2, screw column 4, mounting sleeve body 13 and connecting screw 11 provided by the utility model, the mounting hole 3 on the door panel 2 provides an installation space for the screw column 4, the mounting sleeve body 13 and the connecting screw 11, and the mounting sleeve body 13 is detachably mounted on the screw column 4 through the plug-in hole 14 and the connecting column 6. The cross-section of the connecting column 6 is a quadrilateral. When the connecting screw 11 is tightened on the mounting sleeve body 13, the mounting sleeve body 13 cannot rotate on the connecting column 6, thereby avoiding the connection screw 11 from being unable to be screwed into the mounting sleeve body 13, thereby improving the stability of the connection between the connecting screw 11 and the mounting sleeve body 13.

[0026] Further, in order to connect the connecting screw 11 with the mounting sleeve body 13, refer to Figure 3and Figure 6-7 As shown, a second threaded hole 10 is formed at one end of the mounting sleeve body 13 close to the connecting screw 11, and one end of the connecting screw 11 is screwed into the second threaded hole 10. When the connecting screw 11 is screwed on the mounting sleeve body 13 through the second threaded hole 10, the length of the connecting screw 11 can be adjusted, so that the lock body 1 is easily installed on the door panel 2.

[0027] In the present utility model, combined with Figure 3 As shown, a plurality of slots 8 for adjusting the axial length are provided at equal intervals in the axial direction on both sides of the installation sleeve body 13 of this embodiment, and one end of the clamping member can be clamped in two corresponding slots 8 respectively.

[0028] As mentioned above, when using the multiple card slots 8 provided by the utility model, the installation sleeve body 13 is sleeved on the connecting column 6 through the plug hole 14. At this time, the card block 9 is engaged in the card slot 8 on the side of the installation sleeve body 13 close to the connecting column 6. At this time, the length of the installation sleeve body 13 is the longest. The installation sleeve body 13 passes through the installation hole 3 from one side of the door panel 2, so that the end of the installation sleeve body 13 is on the other side of the door panel 2. At this time, it is convenient for the connecting screw 11 and the installation sleeve body 13 to dock outside the installation hole 3, reducing the connection screw The difficulty of docking the rod 11 with the mounting sleeve is that after the connecting screw 11 is docked with the mounting sleeve body 13, the connecting screw 11 is pressed inwardly, thereby driving the mounting sleeve body 13 to be pushed inwardly on the connecting column 6, thereby shortening the length of the mounting sleeve body 13. When the length of the mounting sleeve body 13 is shortened by a certain length, the clamping block 9 is clamped in the corresponding clamping groove 8 to prevent the mounting sleeve body 13 from moving outward on the connecting column 6. At this time, the connecting screw 11 is tightened, so that one end of the connecting screw 11 is screwed into the mounting sleeve body 13.

[0029] In the present utility model, combined with Figure 7 As shown, the clamping member of this embodiment includes two clamping blocks 9, which are symmetrically installed on both sides of one end of the connecting column 6. The clamping blocks 9 are right-angled triangles, and the inclined surface of the triangle of the clamping blocks 9 faces one side of the mounting sleeve body 13.

[0030] As mentioned above, when using the clamping member provided by the utility model, when the clamping block 9 is on the inner side of the clamping groove 8, part of the clamping block 9 is engaged in the clamping groove 8, and when the mounting sleeve body 13 is pulled toward the side away from the connecting column 6, the mounting sleeve body 13 abuts against the right-angled side on the clamping block 9 through the clamping groove 8. At this time, the mounting sleeve body 13 is restricted on the connecting column 6 by the clamping block 9. When the mounting sleeve body 13 is pushed toward the side close to the connecting column 6, the clamping groove 8 on the mounting sleeve body 13 abuts against the hypotenuse on the clamping block 9. At this time, the clamping block 9 is subjected to force and disengages from the clamping groove 8 inward through the hypotenuse, thereby facilitating the length adjustment of the mounting sleeve body 13 on the connecting column 6.

[0031] Further, in order to allow the card block 9 to be separated from the card slot 8, refer to Figure 2 and Figure 4 As shown, an opening 7 is further provided along the axial direction at one end of the connecting column 6 close to the installation sleeve body 13, and the opening 7 is used for the two clamping blocks 9 to elastically approach or elastically move away inward. The opening 7 can be provided on the connecting column 6 for the two clamping blocks 9 to elastically approach inward, thereby facilitating the clamping blocks 9 to be separated from the clamping groove 8, and at this time, facilitating the installation sleeve body 13 to move axially on the connecting column 6, thereby adjusting the length of the installation sleeve body 13.

[0032] The utility model also provides a door lock, such as Figure 1-2 As shown, it includes a door lock mounting sleeve body 13 disclosed above, a lock body 1 is provided on both sides of the door panel 2, the lock body 1 includes an outer shell and an inner shell, a first threaded hole 5 for accommodating a screw column 4 is opened on the inner side of the outer shell, and an inner hole 12 for accommodating a connecting screw 11 is opened on the inner side of the inner shell.

[0033] As mentioned above, when using the lock body 1 provided by the utility model, the outer shell in the lock body 1 provides an installation position for the screw column 4, and the screw column 4 can be removably installed on the outer shell through the first threaded hole 5. The inner shell in the lock body 1 provides an installation position for the connecting screw 11, and the connecting screw 11 can be removably installed on the inner shell through the recessed hole 12.
