[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] The utility model provides a door lock, the working principle of which is to stabilize the striker shaft through a locking assembly composed of a rotor, a release rotor, a connecting handle and a recovery member, so as to reduce the shaking of the door panel and improve the stability of the door panel after locking.

[0033] The utility model is further described in detail below in conjunction with embodiments and specific implementation methods.

[0034] like Figure 1-Figure 4 As shown, a door lock comprises a lock body 1 and a striker 2 that cooperate with each other;

[0035] The lock body includes a mounting assembly and a locking assembly arranged in the mounting assembly;

[0036] The installation assembly includes a front support plate 111 and a rear support plate 112 respectively arranged on both sides of the locking assembly. The front support plate and the rear support plate are symmetrically arranged, and the tops of the front support plate and the rear support plate are both provided with a mounting groove 113; the two sides of the front support plate and the rear support plate are bent to form a protective baffle 114, and the four protective baffles protect the locking assembly. A U-shaped rubber block 115 is arranged in the placement groove opened on the front support plate. An auxiliary plate 116 is also arranged on the outer side wall of the rear support plate.

[0037] The locking assembly comprises a rotor 121 arranged in the mounting assembly, a release rotor 122 matched with the rotor, a connecting handle 123 arranged on the release rotor, and a recovery member arranged in the mounting assembly and capable of recovering the rotor and the release rotor; a groove 1211 is arranged on the side wall of the rotor directly facing the release rotor, and in the locked state, the rotor is located at the upper and lower ends of the groove and contacts the side wall of the release rotor; the rotor and the release rotor are planar structures and are located in the same vertical plane;

[0038] The recovery member includes two recovery units, which are respectively mounted on the rotor and the release rotor; the recovery unit includes a through hole 1241 arranged on the rotor or the release rotor, a fixed shaft 1242 matched with the through hole, and a torsion spring 1243 arranged at the head end of the fixed shaft; the tail end of the fixed shaft passes through the through hole and is fixedly connected to the rotor or the release rotor; the tail end of the fixed shaft is also provided with a gasket 1244, which is arranged close to the rear support plate. The protective baffle on the front support plate provides support for the torsion spring.

[0039] The striker includes a striker plate 21 in an inverted U shape and a striker shaft 22 arranged horizontally between two vertical portions of the striker plate; the striker shaft is perpendicular to the rotor and the plane where the release rotor is located.

[0040] The specific use steps of the utility model are as follows: Figure 1-Figure 4 As shown, the rubber block 115 is clamped on the front support plate 111 through the mounting groove 113. The front support plate 111, the rear support plate 112 and the auxiliary plate 116 are connected together through the fixed shaft 1242, the rotor 121 passes through one of the fixed shafts 1242, the release rotor 122 passes through the other fixed shaft, the gasket 1244 passes through the fixed shaft, the torsion spring 1243 passes through the fixed shaft, one end is fixed to the front support plate 111, and the other end is fixed to the rotor 121, the torsion spring 1243 passes through the fixed shaft 1242 and one end is fixed to the protective baffle of the front support plate, and the other end is fixed to the rotor or the release rotor; the connecting handle 123 is riveted to the release rotor 122 through the functional unit rivet, and the striker plate 21 is welded to the striker shaft 22.

[0041] The working principle is as follows: when the rotor 121 and the release rotor 122 in the lock body are in an engaged state, the lock is in a locked state, and the striker 2 is locked. When the connecting handle 123 is pulled, the connecting handle drives the release rotor 122, the rotor 121 is bounced open and is in a non-engaged state, the lock is in an open state, and the striker 2 can escape. And it can automatically return to the initial state under the action of the torsion spring.

[0042] When the lock body 1 locks the striker 2, the rubber block 115 has a shock-absorbing effect, thereby reducing the wear of the lock body and the striker and also reducing noise.

[0043] Through the above method, a door lock provided by the utility model stabilizes the bolt shaft through a locking assembly composed of a rotor, a release rotor, a connecting handle and a recovery piece, and reduces the impact sound of the bolt shaft during operation through a rubber block, thereby achieving the purpose of reducing the shaking of the door panel, reducing the wear of various components of the locking assembly, reducing the wear between the door lock and the lock buckle, and improving the stability of the door panel after locking.

[0044] The above is only a preferred implementation of a door lock disclosed by the present utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present utility model, which all belong to the protection scope of the present utility model.
