Referring to fig. 1, 3 and 4, the lock assembly according to the present invention includes a lock housing 100, a buckle 200 mounted on a door frame, the buckle 200 having a lock slot 201 for receiving a bolt 110 when the door is closed, the bolt 110 abutting against a slot wall of the lock slot 201 to achieve a locking function. The inner wall of the locking groove 201 is provided with a first magnet 300. The door lock assembly further includes a latch 110 coupled to a slide bar 112, the slide bar 112 being slidably coupled to the housing 100. it will be appreciated that the latch 110 is retracted when the slide bar 112 slides toward the housing 100, and the latch 110 is extended when the slide bar 112 slides toward the strike 200.

Referring to fig. 3, the sliding rod 112 is provided with an inclined guide block 114, the lock case 100 is slidably connected with a support block 120, the support block 120 is connected with a positioning spring 121, the positioning spring 121 is fixedly connected with the lock case 100, specifically, the lock case 100 is provided with a guide block, the guide block is provided with a guide groove of the sliding rod 112 and a guide groove of the support block 120 to limit the linear motion of the sliding rod 112 and the support block 120, one end of the positioning spring 121 is connected to the support block 120, and the other end is connected to the guide block. The positioning spring 121 is in a compressed state in a normal state, and elastically deforms to generate an elastic force to the support block 120. The upper end of the support block 120 has a front inclined surface and a rear inclined surface, and in the door open state, the elastic force applied by the positioning spring 121 is transmitted to the pushing force of the rear inclined surface to the inclined guide block 114, so that the inclined guide block 114 maintains the position state abutting against the rear inclined surface, and the latch tongue 110 maintains the state of being retracted into the lock case 100.

The bolt 110 is provided with the second magnet 310, when the door is closed, the lock case 100 is close to the buckle plate 200, the second magnet 310 and the first magnet 300 generate magnetic force, and the magnetic force is greater than the thrust of the support block 120 to the inclined guide block 114, the sliding rod 112 moves towards the buckle plate 200 under the influence of the magnetic force, and the bolt 110 extends out and is clamped into the lock slot 201, so that locking is realized. Need not the user and close the door through direct striking door frame and realize locking, reduced the noise when closing the door, also reduced spring bolt 110 because of the loss that the physics striking brought, and then increase spring bolt 110's life-span, reduce spring bolt 110's maintenance, replacement cost, promoted user's use and experienced.

Referring to fig. 3 and 4, the buckle 200 and the bolt 110 are made of nylon plastic. It should be noted that the buckle plate 200 and the latch bolt 110 are respectively provided with the first magnet 300 and the second magnet 310, and the magnets can generate a magnetic field and attract ferromagnetic substances, the ferromagnetic substances generally include metals such as iron, nickel, cobalt, etc., and such metals are generally used as materials in the manufacturing of hardware locks, but the buckle plate 200 and the latch bolt 110 of the embodiment of the present invention are preferably made of nylon plastics, have certain material strength, and are not affected by the magnetic force of the first magnet 300 and the second magnet 310, so as to facilitate installation, and also avoid that the first magnet 300 and the second magnet 310 cannot be attracted to each other when the door is closed, which affects the locking function of the door lock assembly.

Referring to fig. 2 and 3, the latch tongue 110 is provided with an adsorption groove 111, the second magnet 310 is clamped into the adsorption groove 111, and an opening of the adsorption groove 111 faces the buckle 200. Specifically, the latch tongue 110 made of nylon plastic wraps the second magnet 310, physically interferes with the magnetic force field of the second magnet 310, slows down the influence of the second magnet 310 on the lock case 100 or other components, and the opening of the absorption groove 111 faces the position of the first magnet 300 installed on the buckle plate 200, thereby ensuring that the latch tongue 110 can extend out under the action of magnetic force. It should be noted that the magnetic pole of the first magnet 300 facing the latch tongue 110 is different from the magnetic pole of the second magnet 310 facing the buckle 200, and an attractive force is generated between the first magnet 300 and the second magnet 310, and the attractive force drives the latch tongue 110 to extend.

Referring to fig. 1, the lock case 100 is provided with a relief opening 101, and it should be noted that, the size of the relief opening 101 is at least equal to that of the bolt 110, so as to ensure that the bolt 110 can be completely retracted, so as to prevent the bolt 110 from partially extending out, and when a user is scratched or closes a door in daily use, the extended part still collides with a door frame, generates noise, and damages the bolt 110. When the latch 110 retracts, the latch 110 abuts against the sidewall of the docking port 101. Specifically, the arrangement of the abdicating opening 101 can reduce the probability that the second magnet 310 in the bolt 110 is attached to the lock case 100 or other parts in the lock case 100 and cannot extend out, further, the connection relationship between the bolt 110 and the lock case 100 does not need to be tightly matched, interference between parts is reduced, the difficulty of manufacturing and assembling is reduced, and further, the production cost is reduced.

Referring to fig. 1 and 2, the lock case 100 is rotatably connected with an inner square sleeve 130 and an outer square sleeve 140, the inner square sleeve 130 abuts against the outer square sleeve 140, the inner square sleeve 130 is provided with a pulling piece 131, the sliding rod 112 is provided with a driving piece 113, and the pulling piece 131 abuts against the driving piece 113. It can be understood that, here interior side cover 130, outside cover 140 all are connected with handle or circular twisting hand, the user accessible pushes down or the rotatory interior side cover 130 that lets of grip, outside cover 140 is rotatory, and interior side cover 130 is connected with plectrum 131, when interior side cover 130 rotates, drive plectrum 131 and remove, plectrum 131 butt drive plate 113 and drive the slide bar 112 of connecting drive plate 113 and move towards lock shell 100 in, and then drive the withdrawal of spring bolt 110, realize opening the door, in order to make things convenient for the user to open the door.

Referring to fig. 5, the inner square sleeve 130 is provided with a through hole 132, the outer square sleeve 140 is provided with a linkage groove 141, the inner square sleeve 130 is connected with a clutch pin 160, the clutch pin 160 only penetrates through the through hole 132 when locking, the clutch pin 160 penetrates through the through hole 132 and the linkage groove 141 when unlocking, and the inner square sleeve 130 can be driven to rotate by rotating the outer square sleeve 140. It can be understood that, in the locking state, the user rotates or screws the outer square sleeve 140 from the outside of the door, the outer square sleeve 140 can only idle and cannot drive the lock tongue 110 to retract so as to open the door, and in the unlocking state, the user rotates or screws the outer square sleeve 140 from the outside of the door, the outer square sleeve 140 drives the inner square sleeve 130 to rotate through the linkage of the clutch pin 160, and then drives the lock tongue 110 to retract so as to open the door. The anti-theft function of the door lock assembly is added, the used structure is simple, the raw materials are few, and the door lock assembly is easy to produce and manufacture.
