[0002] A door assembly is a functional device used to close or open an opening. It is widely used in residential buildings, office buildings, apartments, hotels, supermarkets, and control cabinets. It consists of a door leaf structure, a door frame structure, and a lock mechanism. The door leaf structure is rotatably connected to the door frame, and the lock mechanism is mounted on the door leaf structure and also snaps into the door frame structure.

[0003] The lock structure of the related technology includes a lock shell, a lock core, a key hole stopper and a key body. The lock shell is provided with a connected storage cavity and a connecting key hole. The lock core is located in the storage cavity and is rotatably connected to the lock shell. A lock tongue portion is provided at the end of the lock core facing away from the connecting key hole. The key hole stopper is located in the storage cavity and is movably connected to the lock shell. The key hole stopper abuts against the lock core. The key body is passed through the connecting key hole so that the key body and the lock core are matched and connected, such as the Chinese patent No. CN201510175566.2.

[0004] However, since the keyhole stopper is located in the storage cavity and is movably connected to the lock shell, the keyhole stopper abuts against the lock core, so that the lock core is separated from the outside world by the combined action of the keyhole stopper and the lock shell; in the process of the operator drilling the lock structure, the drill bit of the drill tool acts on the keyhole stopper to drill the lock structure, and the keyhole stopper is in the shape of a flat plate, so that the drill bit of the drill tool can more easily act on the keyhole stopper, so that the drill bit of the drill tool can more easily drill the keyhole stopper, thereby making it easier for the drill bit of the drill tool to act on the lock core through the keyhole stopper, so that the drill bit of the drill tool can more easily damage the lock core, making the lock structure more likely to fail, and further making the lock structure less stable in use.

[0032] In this embodiment, the key body 300 is respectively connected with the end cover body 210 and the lock core body 220. The lock core body 220 is located in the storage cavity 110 and is rotatably connected to the lock housing 100. The end cover body 210 is located outside the storage cavity 110 and is connected to the lock core body 220, so that the operator drives the lock core body 220 to rotate relative to the lock housing 100 by rotating the key body 300, and at the same time, the end cover body 210 rotates with the lock core body 220 relative to the lock housing 100.

[0033] The lock structure 10 described above has the lock core 220 located in the storage cavity 110 and rotatably connected to the lock housing 100, and the end cover body 210 is located outside the storage cavity 110 and connected to the lock core 220, so that the lock housing 100 and the end cover body 210 act together to cover the lock core 220, that is, the lock core 220 is separated from the outside world by the joint action of the end cover body 210 and the lock housing 100; in the process of the operator drilling the lock structure 10, the drill bit of the drill tool acts on the end cover body 210 to drill the lock structure 10, the first anti-drilling needle 400 is penetrated by the first mounting hole 212 and is rotatably connected to the end cover body 210, and when the drill bit of the drill tool drills through the end surface of the end cover body 210, the drill bit of the drill tool acts on the first anti-drilling needle 400, and the first anti-drilling needle 400 is subjected to force at the first mounting hole The drill bit 400 of the drill tool rotates in the hole 212, so that the drill bit of the drill tool is deflected under the rotation of the first anti-drilling needle 400, thereby making it difficult for the drill bit of the drill tool to continuously act on the first anti-drilling needle 400, so that it is difficult for the drill bit of the drill tool to drill through the first anti-drilling needle 400, and making it difficult for the drill bit of the drill tool to act on the end cover body 210 under the action of the first anti-drilling needle 400, thereby avoiding the problem in the prior art that the drill bit of the drill tool is easy to act on the lock hole stopper, and making it difficult for the drill bit of the drill tool to drill into the end cover body 210 under the action of the first anti-drilling needle 400, thereby making it difficult for the drill bit of the drill tool to act on the lock core 220 through the end cover body 210, so that it is difficult for the drill bit of the drill tool to damage the lock core 220, and making it difficult for the lock structure 10 to fail under the action of the first anti-drilling needle 400, thereby improving the stability of the lock structure 10 in use.

[0034] like Figures 2 to 4 As shown, in one embodiment, the lock core 220 is further provided with a second mounting hole 222, and there is an angle between the extension direction of the connecting groove 221 and the extension direction of the second mounting hole 222, and the second mounting hole 222 is located at the end of the lock core 220 away from the end cover body 210; the lock structure 10 also includes a second anti-drill pin 500, which is passed through the second mounting hole 222 and is rotatably connected to the lock core 220, and the second anti-drill pin 500 is located in the storage cavity 110.

In this embodiment, the operator rotates the key body 300 to drive the lock core 220 to rotate relative to the lock housing 100. The rotation of the lock core 220 is used to drive the bolt portion 600 to slide relative to the lock housing 100.

[0037] like Figures 1 to 4 As shown, in one embodiment, the lock structure 10 further includes an elastic member 700. The lock tongue portion 600 defines a first groove 610, which is in communication with the receiving cavity 110 and the connecting groove 120.

In this embodiment, the elastic member 700 is a spring.

[0038] In one embodiment, the locking tongue portion 600 is an integrally formed structure, so that the locking tongue portion 600 has a higher structural strength.

[0039] like Figures 1 to 4 As shown, in one embodiment, the angle between the extension direction of the connecting lock hole 211 and the extension direction of the first mounting hole 212 is 90°; the angle between the extension direction of the connecting slot 221 and the extension direction of the second mounting hole 222 is 90°.

[0040] In one embodiment, the lock housing 100 is an integrally formed structure, so that the lock housing 100 has a high structural strength.

[0041] In one embodiment, the end cover 210 and the lock core 220 are integrally formed, so that the connection strength between the end cover 210 and the lock core 220 is better, thereby improving the structural stability of the lock body 200.

[0042] like Figure 2 and Figure 4 As shown, in one embodiment, the lock structure 10 further includes a plug body 800, which is located in the storage cavity 110; the lock core 220 further has a second groove 223, which is connected to the storage cavity 110, and the plug body 800 is located in the second groove 223 and connected to the lock core 220.
