Problems solved by technology
[0002] In the door locks currently on the market, a limiting part is provided on the rotating body. The limiting part is to limit the rotation of the outer rotating body according to the opposite angle of unlocking. When the angle rotation exceeds a certain angle, the door lock can be opened by the limiting part without leaving the pin, which brings hidden dangers to safety. In order to solve this problem, door locks on the market are often provided with another door lock housing A limiting part, the limiting part is to prevent the outer rotation body from rotating beyond a certain angle according to the unlocking angle, for example, to limit the outer rotation body within a 50-degree rotation angle according to the unlocking direction, but when in use, if the outer rotation body is forced to When the body rotates more than 50 degrees according to the unlocking angle, the limit part set on the door lock shell will be damaged, so that the outer rotating body has no rotation angle limit. In this case, the door lock will be opened destructively, resulting in safety hazards. greatly reduced sex

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as Figure 1 ~ Figure 3 As shown, a door lock swivel assembly includes a swivel 4 and an outer swivel 7 and an inner swivel 11 arranged inside the swivel. The swivel 4 is provided with a notch 1, and the notch of the swivel 4 1 is provided with a hinge 3, and the hinge 3 is fixed on one side of the notch 1 of the swivel body 4 by a pin 9, and the outer swivel body 7 is provided with a protrusion 5, and the protrusion 5 and the The leaves 6 of the hinge 3 form a staggered pattern. Through this interlacing, the rotation of the protrusion 5 can drive the cooperation of the leaf 6, and at the same time, there is an elastic member for recovery between the hinge 3 and the swivel 4, and the elastic member can preferably be a torsion spring 2. The hinge 3 is close to one side of the notch 1 of the swivel 4. This setting makes the hinge 3 ...

The invention discloses a door lock swivel component which comprises a swivel as well as an outer swivel and an inner swivel which are arranged inside the swivel, wherein the swivel is provided with a notch; a hinge is arranged at the notch of the swivel; the hinge is fixed on the swivel through a dowel; the outer swivel is provided with a bulge; the bulge and the hinge are arranged in a staggered manner. Due to the arrangement of the hinge, as the hinge is tightly adhered to the inner side of the swivel, when the outer swivel rotates towards a direction opposite to the unlocking direction, a limiting function is achieved, and when the outer swivel rotates towards the direction of a locking angle, the hinge can be bounced off under the action of the bulge of the outer swivel, and is automatically reset through a torsional spring, so that a door lock cannot be unlocked no matter how the outer swivel rotates towards the direction of the locking angle.
