A magnetic attracting member 110 is provided on the front side of the main body 100. The connecting member 200 includes a connecting portion 220 and a strengthening portion 210. The strengthening portion 210 is provided at the rear end of the connecting portion 220. The connecting structure 300 is provided between the connecting portion 220 and the main body 100. The main body 100 can be installed at the bottom of the connecting portion 220 through the connecting structure 300. Among them, the strengthening portion 210 extends downward and abuts against the rear side of the main body 100. The connecting member 200 can be fixedly connected to the upper part of the door frame, and the main body 100 is connected to the bottom of the connecting portion 220 through the connecting structure 300. By providing the strengthening portion 210, the strengthening portion 210 can abut against the rear side of the main body 100. The front side of the main body 100 is attracted to the door body through the magnetic attracting member 110. The impact generated by closing the door and attracting can be supported by the strengthening portion 210, thereby reducing the impact on the connecting structure 300, making the connecting structure 300 not easily damaged or loosened, and further enabling the magnetic lock to be used stably for a long time.

[0030] Specifically, the connecting member 200 is fixedly connected to the top of the door frame. The main body 100 is installed on the door frame through the connecting member 200, that is, the main body 100 is installed at the bottom of the connecting portion 220 through the connecting structure 300. A magnetic member is provided on the front side of the main body 100. The magnetic member is attracted to the door body under force, so that the main body 100 will be subjected to a lateral force impact. By extending the strengthening portion 210 downward at the rear end of the connecting portion 220, the strengthening portion 210 can extend to the rear side of the main body 100, so that the rear side of the main body 100 can abut against the strengthening portion 210, thereby being able to support the lateral force of the door body attraction, reducing the force on the connecting structure 300, making the connecting structure 300 not easily damaged, and further improving the impact resistance of the lock body.

[0031] Referring to Figures 1 to 4 , in some embodiments of the present utility model, the strengthening portion 210 extends along the length direction of the main body 100, which can improve the lateral support strength of the main body 100. Specifically, the protruding portion 120 and the strengthening portion 210 can extend along the entire length direction of the main body 100, which can expand the support range as much as possible and improve the support strength.

When the rear side surface of the main body 100 abuts against the reinforcing part 210, the first connection hole 320 and the second connection hole 330 can be aligned, so that the fastening bolt 310 can connect the main body 100 to the connecting member 200 through the first connection hole 320 and the second connection hole 330.

[0033] Specifically, the connection part 220 can be a horizontally arranged plate member. The second connection hole 330 can be provided on the connection part 220, and the first connection hole 320 can be correspondingly provided at the top of the main body 100. During installation, the fastening bolt 310 can pass through the first connection hole 320 and be threadedly connected to the second connection hole 330 to connect the main body 100 to the connecting member 200. Without the reinforcing part 210, when the main body 100 is horizontally stressed, only the fastening bolt 310 can bear the force. The fastening bolt 310 is subjected to shear force for a long time and is prone to damage or looseness. After the reinforcing part 210 is provided, on the one hand, the force borne by the fastening bolt 310 can be reduced, and on the other hand, during installation, the abutting and positioning can be carried out through the reinforcing part 210, so as to facilitate the alignment of the first connection hole 320 and the second connection hole 330 and facilitate the installation of the fastening bolt 310.

[0034] Referring to Figures 1 to 4 , in some embodiments of the present utility model, the reinforcing part 210 has a positioning groove 211. The positioning groove 211 has a first abutting surface 2111 and a second abutting surface 2112. The first abutting surface 2111 abuts against and positions the top of the main body 100, and the second abutting surface 2112 abuts against and positions the rear side surface of the main body 100.

[0035] Specifically, the reinforcing part 210 can be machined to form the positioning groove 211.

If water enters, the water can flow into the first guide groove 132 and will not accumulate on the magnetic component and the circuit board. The water can be discharged through the first guide groove 132 in time and it is not easy to form accumulated water inside. At the same time, the first guide groove 132 can also form a heat dissipation air duct to facilitate the heat dissipation of the magnetic attraction component 110 and the circuit board.

[0039] Referring to Figures 3 to 4 , in some embodiments of the present utility model, a protruding portion 120 is provided on the rear side surface of the housing 130. The first guide groove 132 is located at the protruding portion 120, and a second guide groove 400 is defined between the protruding portion 120 and the strengthening portion 210. Specifically, by machining the first guide groove 132 at the protruding portion 120, the occupied space of the housing 130 can be reduced and the structure is more compact. The protruding portion 120 also abuts against the door frame. The protruding portion 120 and the strengthening portion 210 jointly abut against the door frame, so that a second guide groove 400 is formed therebetween. The second guide groove 400 can discharge the accumulated water from both ends of the second guide groove 400, and the second guide groove 400 can form a heat dissipation air duct for the magnetic lock to dissipate heat, and can increase the heat dissipation area of the magnetic attraction component 110, thereby improving the heat dissipation effect.
