Based on the movement, the two limit pins 19 are respectively movably inserted into the corresponding plug blocks 18 to limit the outer lock body 6 from being separated from the mounting plate 9.

[0028] As mentioned above, when using the door body 3, inner lock body 1, outer lock body 6, mounting plate 9 and connecting parts provided by the present invention, when installing the smart lock, the mounting plate 9 is directly fixed to the door body 3 through multiple connecting parts, the outer lock body 6 is snapped onto the mounting plate 9 through the insert block 18 and the limit pin 19, and then the inner lock body 1 is installed on the inner side of the door body 3. At this time, since the insert block 18 and the limit pin 19 are between the outer lock body 6 and the mounting plate 9, the outer lock body 6 cannot be removed from the mounting plate 9 from the outside of the door body 3. In addition, since the strength of the insert block 18 and the limit pin 19 is greater than the strength of the original screw 8 and the screw sleeve, the outer lock body 6 can be prevented from being violently removed from the mounting plate 9.

[0029] Further, in order to facilitate the detachable installation of the mounting plate 9 on the door body 3, refer to Figure 1-3 As shown, the connecting member includes a fastening bolt 7. A plurality of recessed holes 5 are formed on the edge of the mounting plate 9. Each fastening bolt 7 is respectively disposed in a corresponding recessed hole 5, and one end of each fastening bolt 7 extends into the door body 3. The mounting plate 9 is detachably mounted on the door body 3 via the plurality of fastening bolts 7. When the outer lock body 6 is mounted on the mounting plate 9, the fastening bolts 7 cannot be operated, thereby preventing the mounting plate 9 from being separated from the door body 3.

[0030] Further, in order to facilitate the detachable installation of the inner lock body 1 on the mounting plate 9, refer to Figure 2 As shown, the mounting cavity is further provided with two mounting members for connecting the inner lock body 1 and the mounting plate 9. The mounting members include a screw sleeve 2 and a screw rod 8, one end of which is welded to the inner side of the mounting plate 9, and one end of which is detachably mounted on the inner side of the inner lock body 1. The screw sleeve 2 and the screw rod 8 are prior art. In the prior art, the screw rod 8 is mounted on the outer lock body 6, while in the present invention, the screw rod 8 is mounted on the mounting plate 9. When installing the inner lock body 1, reference can be made to the prior art installation method.

[0031] Further, in order to improve the stability of the outer lock body 6 on the mounting plate 9, refer to Figure 2 and Figure 4 As shown, the inner side of the outer lock body 6 is further provided with a groove 4, through which the outer lock body 6 covers the outside of the mounting plate 9. When the insert 18 is restrained by the limit pin 19, the outer lock body 6 covers the mounting plate 9 through the groove 4, and the outer lock body 6 does not shake on the mounting plate 9.

[0032] In this utility model, combined with Figure 1-3 As shown, the mounting plate 9 of this embodiment is further penetrated by an opening 10 communicating with the mounting cavity, and a driving member for driving the limiting pin 19 is further provided in the opening 10 .

[0033] Combine Figure 5-6As shown, a slot 12 for accommodating the insert block 18 is provided on the outside of the mounting plate 9 , a mounting chamber 13 for accommodating the drive member is provided between the slot 12 and the opening 10 , and one end of the limiting pin 19 extends into the mounting chamber 13 .

[0034] Combine Figure 5-6 As shown, the driving member includes a pull ring 11 and a connecting rod 16 installed between the pull ring 11 and the limit pin 19. A mounting plate 9 is provided in the mounting compartment 13. The connecting rod 16 is movably installed on the mounting plate 9. The pull ring 11 is set in the opening 10.

[0035] As mentioned above, when using the driving member provided by the present invention, the slot 12 is used to facilitate the insertion block 18 on the outer lock body 6 to be inserted into the mounting plate 9. At this time, the pull ring 11 and the connecting rod 16 can drive the limit pin 19 in the mounting compartment 13 to be inserted into the latch, so that one end of the limit pin 19 is inserted into the insertion block 18, thereby preventing the outer lock body 6 from being separated from the mounting plate 9. When the outer lock body 6 needs to be removed, the lock core is taken out of the mounting cavity. At this time, the pull ring 11 is adjusted from the inner side of the door body 3 through the mounting cavity, so that the limit pin 19 is separated from the insertion block 18. At this time, the outer lock body 6 can be removed from the mounting plate 9.

[0036] Further, in order to prevent the limit pin 19 from being separated from the insert block 18, refer to Figure 5-6 As shown, the installation chamber 13 is further provided with a pushing mechanism mounted on the connecting rod 16. The pushing mechanism is used to push the limit pin 19 into the slot 12 at all times. The pushing mechanism includes a spring 15 and a retaining ring 17. Both the spring 15 and the retaining ring 17 are mounted in the installation chamber 13, and the retaining ring 17 is welded to the connecting rod 16. The spring 15 is arranged on the side of the installation chamber 13 away from the limit pin 19, and the spring 15 is sleeved on the connecting rod 16. When the pull ring 11 is pulled outward in the opening 10, the limit pin 19 is driven into the installation chamber 13 via the connecting rod 16. At this time, the retaining ring 17 on the connecting rod 16 drives the spring 15 to compress in the installation chamber 13. When the pull ring 11 is released, the elastic force of the spring 15 is released, thereby driving the limit pin 19 to automatically insert into the through hole 14 in the insert block 18. When the pull ring 11 is not pulled, the limit pin 19 will not be separated from the insert block 18.

[0037] Further, in order to facilitate the insertion of the limit pin 19 into the insert block 18, refer to Figure 5As shown, the insert block 18 has a through hole 14 extending therethrough, into which one end of a stop pin 19 can be inserted. The stop pin 19 has a cutout angle on its outer portion near one end of the insert block 18. When the insert block 18 is inserted into the slot 12, the insert block 18 first abuts against the cutout angle, thereby automatically retracting the stop pin 19 into the mounting compartment 13, facilitating insertion of the insert block 18 into the slot 12. When the through hole 14 on the insert block 18 is at the end of the stop pin 19, the stop pin 19 automatically inserts into the through hole 14 under the elastic force of the spring 15, thereby retaining the insert block 18 in the slot 12.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
