[0026] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figure 1 , Figure 3 and Figure 4 , is a door lock assembly proposed by the present invention, including a lock housing 100, a gusset plate 200, which is installed on a door frame, and the gusset plate 200 is provided with a lock slot 201, which is used to insert a lock tongue 110 when closing the door, and the lock tongue 110 abuts against the slot wall of the lock slot 201 to achieve the locking function. The inner wall of the lock slot 201 is provided with a first magnet 300. The door lock assembly also includes a lock tongue 110, which is connected to a slide bar 112, and the slide bar 112 is slidably connected to the lock housing 100. It can be understood that when the slide bar 112 slides toward the lock housing 100, the lock tongue 110 can be driven to retract, and when the slide bar 112 slides toward the gusset plate 200, the lock tongue 110 can be driven to extend.

[0029] Reference Figure 3 , the slide bar 112 is provided with an inclined guide block 114, the lock housing 100 is slidably connected with a support block 120, the support block 120 is connected with a positioning spring 121, and the positioning spring 121 is fixedly connected to the lock housing 100. Specifically, the lock housing 100 is provided with a guide block, and the guide block is provided with a guide groove of the slide bar 112 and a guide groove of the support block 120 to limit the slide bar 112 and the support block 120 to make linear motion, one end of the positioning spring 121 is connected to the support block 120, and the other end is connected to the guide block. Under normal conditions, the positioning spring 121 is in a compressed state, elastically deformed, and an elastic force is generated on the support block 120. The upper end of the support block 120 has a front inclined surface and a rear inclined surface. When the door is opened, the elastic force applied by the positioning spring 121 is transmitted to the rear inclined surface to push the inclined guide block 114, thereby maintaining the position state of the inclined guide block 114 against the rear inclined surface, and the lock tongue 110 remains in the state of retracting the lock housing 100.

[0030] The lock tongue 110 is provided with a second magnet 310. When the door is closed, the lock housing 100 is close to the gusset plate 200. The second magnet 310 and the first magnet 300 generate a magnetic force, and the magnetic force is greater than the thrust of the support block 120 on the inclined guide block 114. The slide bar 112 moves toward the gusset plate 200 under the influence of the magnetic force, and the lock tongue 110 extends and snaps into the lock slot 201 to achieve locking. The user does not need to directly hit the door frame to close the door to achieve locking, which reduces the noise when closing the door and reduces the loss of the lock tongue 110 caused by physical impact, thereby increasing the life of the lock tongue 110, reducing the maintenance and replacement costs of the lock tongue 110, and improving the user experience.

[0031] Reference Figure 3 , Figure 4, the gusset plate 200 and the lock tongue 110 are both made of nylon plastic. It should be noted that the gusset plate 200 and the lock tongue 110 are respectively provided with a first magnet 300 and a second magnet 310, and the magnet can generate a magnetic field and attract ferromagnetic substances. Ferromagnetic substances generally include metals such as iron, nickel, and cobalt. Such metals are generally used as materials in the manufacture of hardware locks. The gusset plate 200 and the lock tongue 110 of the embodiment of the present invention are preferably made of nylon plastic, which has a certain material strength and will not be affected by the magnetic force of the first magnet 300 and the second magnet 310, so as to facilitate installation and avoid the first magnet 300 and the second magnet 310 from being unable to adsorb each other when the door is closed, thereby affecting the locking function of the door lock assembly.

[0032] Reference Figure 2 , Figure 3 , the lock tongue 110 is provided with an adsorption groove 111, the second magnet 310 is inserted into the adsorption groove 111, and the opening of the adsorption groove 111 faces the buckle plate 200. Specifically, the lock tongue 110 made of nylon plastic wraps the second magnet 310, physically interferes with the magnetic field of the second magnet 310, and reduces the influence of the second magnet 310 on the lock case 100 or other components, and the adsorption groove 111 opens toward the position of the first magnet 300 installed on the buckle plate 200, thereby ensuring that the lock tongue 110 can be extended under the action of magnetic force. It should be noted that the magnetic pole of the first magnet 300 facing the lock tongue 110 is different from the magnetic pole of the second magnet 310 facing the buckle plate 200, and an attractive force is generated between the first magnet 300 and the second magnet 310, and the attractive force drives the lock tongue 110 to extend.

[0033] Reference Figure 1 The lock housing 100 is provided with a clearance opening 101. It should be noted that the size of the clearance opening 101 is at least equal to the size of the lock tongue 110, which can ensure that the lock tongue 110 can be fully retracted to prevent the lock tongue 110 from being partially extended. When the user is scratched in daily use or closes the door, the extended part will still hit the door frame, generate noise, and damage the lock tongue 110. When the lock tongue 110 is retracted, the lock tongue 110 abuts against the side wall of the clearance opening 101. Specifically, the provision of the clearance opening 101 can reduce the probability that the second magnet 310 in the lock tongue 110 is adsorbed on the lock housing 100 or other components in the lock housing 100 and cannot be extended. Further, the connection relationship between the lock tongue 110 and the lock housing 100 does not need to be tightly matched, which reduces the interference between components, reduces the difficulty of manufacturing and assembly, and thus reduces the production cost.

[0034] Reference Figure 1 , Figure 2The lock housing 100 is rotatably connected with the inner square sleeve 130 and the 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 paddle 131, the slide bar 112 is provided with a driving plate 113, and the paddle 131 abuts against the driving plate 113. It can be understood that the inner square sleeve 130 and the outer square sleeve 140 are both connected with a handle or a round screw handle, and the user can rotate the inner square sleeve 130 and the outer square sleeve 140 by pressing down or rotating with grip force, and the inner square sleeve 130 is connected with the paddle 131. When the inner square sleeve 130 rotates, the paddle 131 is driven to move, the paddle 131 abuts against the driving plate 113 and drives the slide bar 112 connected to the driving plate 113 to move toward the lock housing 100, thereby driving the lock tongue 110 to retract, and realize opening the door, so as to facilitate the user to open the door.

[0035] Reference Figure 5 1. The inner sleeve 130 is provided with a through hole 132, the outer sleeve 140 is provided with a linkage groove 141, and the inner sleeve 130 is connected with a clutch pin 160. When locking, the clutch pin 160 is only penetrated in the through hole 132, and when unlocking, the clutch pin 160 is penetrated in both the through hole 132 and the linkage groove 141. At this time, rotating the outer sleeve 140 can drive the inner sleeve 130 to rotate. It can be understood that when in the locked state, the user rotates or twists the outer sleeve 140 from outside the door, and the outer sleeve 140 can only rotate idly and cannot drive the lock tongue 110 to retract to open the door. When unlocking, the user rotates or twists the outer sleeve 140 from outside the door, and the outer sleeve 140 drives the inner sleeve 130 to rotate through the linkage of the clutch pin 160, and then drives the lock tongue 110 to retract to open the door. The anti-theft function of the door lock assembly is increased, and the structure used is simple, the raw materials are small, and it is easy to produce.

[0036] Reference Figure 1 , Figure 6The lock housing 100 is fixedly connected to a base 150, and the base 150 is connected to a movable touch slider 151. The top surface of the touch slider 151 is an inclined surface, and the inclined surface abuts against the support block 120 and fits with the top surface of the touch slider 151. Under the state of force, the touch slider 151 can slide along the inclined surface. It can be understood that when the lock tongue 110 is retracted, the inclined guide block 114 pushes the support block 120 to move toward the touch slider 151. Further, the support block 120 pushes the touch slider 151 to move in the direction of the inclined surface, and the surface of the touch slider 151 facing the clutch pin 160 is only provided with a boss 152 on one side. Further, under the push of the support block 120, the boss 152 can abut against the clutch pin 160 and press the clutch pin 160 into the linkage groove 141, thereby realizing the conversion between locking and unlocking. It should be noted that when the user closes the door from the outside, the lock tongue 110 retracts into the lock shell 100 under the gravitational force of the first magnet 300 and the second magnet 310, and the above steps are realized, and the door lock enters the unlocked state. Even if the user does not have a key to open the door, the door can be opened directly by rotating or twisting the outer square sleeve 140 to drive the inner square sleeve 130 to rotate, thereby improving the user experience.

[0037] Reference Figure 6 The base 150 is connected to a limit spring 153, and the end of the limit spring 153 is connected to a limit bead 154 to increase the contact area and stability of the limit spring 153, and prevent the spring from slipping and losing its limit function due to excessive pressure and smooth contact surface. A limit groove is set on the other side of the touch slider 151, and the limit bead 154 is inserted into the limit groove to further ensure the stability of the limit spring 153. It can be understood that when the boss 152 of the touch slider 151 abuts against the clutch pin 160, the limit spring 153 abuts against the touch slider 151, so that the touch slider 151 remains in the current position and abuts against the clutch pin 160, thereby maintaining the unlocked state, so that even if the user forgets to bring the key when closing the door, the clutch pin 160 always links the inner square sleeve 130 and the outer square sleeve 140, and the user can open the door from outside the door, and the linkage effect will not be lost due to the free movement of the touch slider 151, thereby improving the user's experience.

[0038] Reference Figure 2, a clutch reset spring 161 is connected in the linkage groove 141, and the clutch reset spring 161 abuts against the clutch pin 160. It can be understood that the linkage groove 141 is arranged in the outer square sleeve 140. When the touch slider 151 does not abut against the clutch pin 160, the clutch pin 160 pops out of the linkage groove 141 under the elastic force of the clutch reset spring 161. At this time, the rotation of the outer square sleeve 140 cannot drive the inner square sleeve 130 to rotate, that is, it is in a locked state at this time, and the user cannot open the door from the outside. Optionally, the touch slider 151 is fixedly connected with a clutch button, the outer end of the clutch button is located outside the lock housing 100, and the clutch button is used to drive the touch slider 151. With the setting of the clutch return spring 161, when the user needs to lock the door, he only needs to move the touch slider 151 through the clutch button, which facilitates the user's locking method and improves the user's usage experience. When the user wants to unlock the door indoors, he can also directly use the clutch button to move the touch slider 151 to the position abutting the clutch pin 160 to achieve unlocking, enriching the user's usage options.

[0039] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
