Technical Field

[0001] The utility model relates to the technical field of door locks, and particularly relates to a hardware door lock convenient for maintenance. Background Technique

[0002] As the name implies, a door lock is a device used to lock a door to prevent others from opening it. There are many classifications of door locks, and the requirements for door locks vary in different occasions. Ordinary families generally use hardware door locks, which have high security and relatively low prices.

[0003] The above-mentioned door locks often have the following defects: during the long-term use of the door lock, water vapor in the air or rain will cause the lock core inside the door lock to rust, making the door lock unable to be opened. Generally, a rusty hardware door lock needs to be removed and rusted by professional personnel, and it is inconvenient to maintain the hardware door lock by oneself. Therefore, a hardware door lock convenient for maintenance is needed. Content of the Utility Model

[0021] Furthermore, four fog nozzles are fixedly installed on the outer surface of the connecting pipe.

[0022] Through the above technical solution, the fog nozzles can spray lubricating oil over a large area on the lock core.

[0023] Furthermore, the filtering mechanism includes multiple-stage filter membranes. A guide plate is fixedly installed on the inner surface of the lock core box cavity. An oil storage shell is welded and installed on the outer surface of the guide plate, and an oil outlet box is fixedly connected to the lower surface of the oil storage shell.

[0024] Through the above technical solution, the guide plate can direct the excess lubricating oil flowing down from the lock core into the oil storage shell.

[0025] Furthermore, a pull plate is slidably connected to the inner surface of the oil storage shell. The pull plate can slide out of the outer side of the handle box, and multiple-stage filter membranes are installed inside the pull plate.

[0046] A filtering mechanism 5, and the filtering mechanism 5 is arranged below the lock core 3 in the inner cavity of the lock core box 1 for filtering and reusing the excess lubricating oil.

[0047] As Figure 2 、 Figure 3 、 Figure 4 And Figure 7 shown, the lubrication mechanism 4 includes an oil storage tank 41 and an injection pipe 42. The oil storage tank 41 is fixedly installed on the surface of the inner cavity of the oil storage tank 41, and the injection pipe 42 is fixedly installed on the surface of the inner cavity of the oil storage tank 41. A circular groove 44 is opened on the outer surface of the handle box 2, and a connecting pipe 48 is fixedly installed on the inner wall of the inner cavity of the lock core box 1. The injection pipe 42 can transport the lubricating oil in the oil storage tank 41 to the connecting pipe 48.
