[0033] The following further elaborates on the embodiments of the present utility model in conjunction with the accompanying drawings.

[0034] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the screwless electronic lock is installed on the cabinet door 100. The cabinet door 100 is provided with mounting holes 110. The screwless electronic lock includes a lock body 200 and a panel 300. A first cylinder 210 is provided on the front side of the lock body 200. The first cylinder 210 extends in the front-rear direction, and the first cylinder 210 is provided with a first thread 211. A second cylinder 310 is provided on the rear side of the panel 300. The second cylinder 310 extends in the front-rear direction, and the second cylinder 310 is provided with a second thread 311.

[0035] When it is necessary to install the screwless electronic lock on the cabinet door 100, the panel 300 and the lock body 200 are respectively placed on the front and rear sides of the cabinet door 100. The panel 300 is located on the front side of the cabinet door 100, and the lock body 200 is located on the rear side of the cabinet door 100. The second cylinder 310 passes backward through the mounting hole 110, and the first thread 211 is connected to the second thread 311, so that the lock body 200 and the panel 300 are relatively fixed and cooperate to clamp on the cabinet door 100, thereby fixing the lock body 200, the panel 300, and the cabinet door 100 to each other.

[0036] This screwless electronic lock avoids the need to drill multiple positioning holes on the cabinet door 100, that is, there is no need to accurately align the positioning holes, improves the error tolerance rate, and can quickly and conveniently install the screwless electronic lock on the cabinet door 100, saving time and effort.

[0037] According to some embodiments of the present utility model, referring to Figure 2 and Figure 3, the first thread 211 is an internal thread provided on the inner peripheral wall of the first cylinder 210, and the second thread 311 is an external thread provided on the outer peripheral wall of the second cylinder 310. The second cylinder 310 can be inserted into the first cylinder 210 and then threadedly connected to the first cylinder 210. Preferably, one end of the first cylinder 210 is inserted into the mounting hole 110, and the first cylinder 210 is in interference fit with the mounting hole 110. It can be understood that during the assembly process, the first cylinder 210 is inserted into the mounting hole 110 from the back to the front. The diameter of the first cylinder 210 is larger than the inner diameter of the mounting hole 110, so that the first cylinder 210 is in interference fit with the mounting hole 110, and the lock body 200 is relatively fixed to the cabinet door 100. Then, the second cylinder 310 is passed through the mounting hole 110 from the front to the back and then inserted into the first cylinder 210 and threadedly connected to the first cylinder 210. At this time, the lock body 200 is relatively fixed to the cabinet door 100, that is, just rotate the panel 300, and the lock body 200 will not rotate following the rotation of the panel 300. The installation is convenient and there is no need to apply external force to fix the lock body 200. The diameter of the second cylinder 310 is smaller than the inner diameter of the mounting hole 110 to prevent collision with the hole wall of the mounting hole 110 and damage the second thread 311.

[0038] According to some embodiments of the present invention, the first thread 211 is an external thread provided on the outer peripheral wall of the first cylinder 210, and the second thread 311 is an internal thread provided on the inner peripheral wall of the second cylinder 310. The first cylinder 210 can be inserted into the second cylinder 310 and threadedly connected to the second cylinder 310. The outer peripheral wall of the second cylinder 310 is in contact with the inner wall of the mounting hole 110, so as to prevent external liquid from penetrating into the interior of the lock body 200 through the gap between the second cylinder 310 and the mounting hole 110 and damaging the circuit.

[0039] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the side wall of the first cylinder 210 is provided with a first wire arranging hole 220, and the first wire arranging hole 220 extends in the front-rear direction to facilitate wire routing.

[0040] Further, referring to Figure 1 and Figure 2 , the side wall of the second cylinder 310 is provided with a second wire arranging hole 320. When the lock body 200, the panel 300 and the cabinet door 100 are relatively fixed, the first wire arranging hole 220 is aligned with the second wire arranging hole 320, so that the cable in the second cylinder 310 can extend out through the second wire arranging hole 320 and the first wire arranging hole 220 in sequence and be connected to the control board in the lock body 200.

[0041] According to some embodiments of the present utility model, an induction module 330 is provided inside the second cylinder 310. The induction module 330 is electrically connected to the control board inside the lock body 200. The induction module 330 is snap-connected to the second cylinder 310. The induction module 330 can sense fingerprints and feedback them to the control board of the lock body 200. The induction module 330 is located on the front side of the cabinet door 100 to facilitate fingerprint sensing.

[0042] Further, referring to Figure 2 , two symmetrically arranged flat parts 340 are provided on the outer peripheral wall of the panel 300 to facilitate a person's hand to hold the panel 300 or to clamp it with tools such as tweezers to drive the panel 300 to rotate, so as to facilitate the threaded connection between the panel 300 and the lock body 200.
