[0002] A door lock is a device installed on a door to lock the door and enable it to open, close, and lock. Its core function is to ensure the safety and privacy of the space inside the door and to control access.

[0003] When replacing door lock batteries using existing technology, first identify the door lock type and prepare a screwdriver and a new battery of the corresponding model. If the door lock has a low battery alarm, it needs to be dealt with promptly. Locate the battery compartment, open the compartment cover with a tool, remove the old battery, insert the new battery according to the positive and negative markings and ensure good contact, and then close the compartment cover to test whether the unlocking functions such as password and fingerprint are working properly.

[0004] Traditional door locks often use screws to secure the battery compartment, requiring users to prepare additional tools such as screwdrivers for disassembly. This process is cumbersome, and users unfamiliar with these tools are prone to stripping screws or having difficulty removing the cover. Therefore, a door lock that facilitates battery replacement is proposed to solve these problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 , Figure 5 The present invention provides an embodiment of a door lock for easy battery replacement, comprising a door lock 1. The outer wall of the door lock 1 is provided with a sealing mechanism 2 and a fitting mechanism 3. The sealing mechanism 2 includes a rotating shaft 211, the outer wall of which is rotatably connected to the inner wall of the door lock 1. The rotating shaft 211 provides a pivot point for a cover plate 212, allowing the cover plate 212 to rotate around it. The cover plate 212 is fixedly connected to the outer wall of the rotating shaft 211. The cover plate 212 is used to close the battery compartment of the door lock 1, providing protection. The cover plate 212 is elastically connected to the door lock 1 via a torsion spring 213. The elastic force of the torsion spring 213 can spring the cover plate 212 open after the latch is released, facilitating the opening of the battery compartment. The bottom of the cover plate 212 is provided with a sliding groove 214, which provides a track for the sliding of the locking block 215, ensuring the stability of the moving direction of the locking block 215. The locking block 215 is slidably connected to the inner wall of the sliding groove 214. The locking block 215 is used to cooperate with the locking groove 217 on the door lock 1 to realize the locking and fixing of the cover plate 212 and the door lock 1. The locking block 215 is elastically connected to the cover plate 212 through a spring 216. The spring 216 can keep the locking block 215 in an extended state when there is no external force, ensuring a firm locking. The inner surface of the door lock 1 is provided with a locking groove 217, which cooperates with the locking block 215 to make the cover plate 212 stably fixed on the door lock 1.

[0033] Reference Figure 2 , Figure 3 , Figure 5 One end of the torsion spring 213 is fixedly connected to the inner wall of the door lock 1, and the other end of the torsion spring 213 is fixedly connected to the outer wall of the cover plate 212. Through the fixed connection at both ends, the torsion spring 213 can generate an elastic force on the cover plate 212. One end of the spring 216 is fixedly connected to the inner wall of the slide groove 214, and the other end of the spring 216 is fixedly connected to the outer wall of the locking block 215, so that the spring 216 can effectively act on the locking block 215. The sealing mechanism 2 also includes a lifting plate 218. The lifting plate 218 is convenient for user operation. By moving the lifting plate 218, the locking block 215 can be moved. The side wall of the lifting plate 218 is fixedly connected to the side wall of the locking block 215 to ensure that the lifting plate 218 can drive the locking block 215 to move synchronously.

[0034] Reference Figure 4 The bonding mechanism 3 includes a cover groove 311, which is used to accommodate the telescopic rod 312, the rubber arc clamp 313, and the second spring 314, so that these components can be reasonably arranged on the cover plate 212. The bonding mechanism 3 also includes the telescopic rod 312, the outer wall of which is fixedly connected to the inner wall of the cover groove 311. The telescopic rod 312 can restrict the movement direction of the rubber arc clamp 313, so that it stably supports the battery. The bonding mechanism 3 also includes the rubber arc clamp 313, the inner rod of which is fixedly connected to the outer wall of the rubber arc clamp 313. The rubber arc clamp 313 is used to contact the surface of the battery and clamp and fix the battery through elastic deformation. The bonding mechanism 3 also includes the second spring 314, one end of which is fixedly connected to the inner wall of the telescopic rod 312, and the other end of which is fixedly connected to the inner rod of the telescopic rod 312. The second spring 314 provides elastic force to the rubber arc clamp 313, so that the rubber arc clamp 313 can adapt to batteries of different sizes and maintain a stable clamping force.

[0035] Working principle: When the battery of door lock 1 needs to be replaced, by pushing the lifting plate 218 upward, the lifting plate 218 moves the locking block 215 fixedly connected to the side wall upward, causing the locking block 215 to slide into the slide groove 214, thereby squeezing the spring 216. The spring 216 is compressed, which can completely disengage the locking block 215 from the inner wall of the groove 217, so that the cover plate 212 is no longer locked to the door lock 1 by the locking block 215. The rebound force of the torsion spring 213 can make the cover plate 212 spring up, thereby exposing the battery compartment on the door lock 1. Then the old battery can be taken out of the battery compartment and the new battery can be put into the battery compartment. The user does not need to prepare screwdrivers or other disassembly tools. He / she can simply push the lifting plate 218 to open the cover plate 212, which reduces the operation threshold of battery replacement.

[0036] After the new battery is replaced, the cover plate 212 can be put back on, so that the clip 215 can be snapped back into the inner wall of the slot 217. After the cover plate 212 is put on, the rubber arc clip 313 can provide elastic support for the battery through the telescopic rod 312 and the spring 314. The contact surface between the rubber arc clip 313 and the battery is made of flexible material, which can effectively prevent the battery surface from being scratched or damaged due to rigid compression, thus ensuring the safety of the battery.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
