DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Embodiment 1 of the present application provides a reverse locking release structure that can be switched left and right.

[0033] See also Figure 1 and Figure 2 As shown, the reverse-lock release structure 1000 includes a handle 1 with a first connection hole 12, a main body 2 with a bearing hole 23, a reverse-lock key 3 disposed inside the main body 2, a reverse-lock toggle arm 4 disposed below the reverse-lock key 3, and a reset cover 5 inserted into the first connection hole 12 from the inside of the main body 2 through the bearing hole 23. The side of the main body 2 facing the inside of the door is the inner side, and the side of the main body 2 facing the outside of the door is the outer side.

[0034] See also Figure 3 As shown, a through bearing hole 23 is provided at the lower end of the main body 2, a sliding groove 21 is provided on the inner side of the waist of the main body 2, and a cylindrical connecting column 22 is provided on the left side between the sliding groove 21 and the bearing hole 23. The sliding groove 21 is used to guide the anti-lock key 3 to move in the axial direction of the slot. In an optional embodiment, in order to reduce the friction between the inner wall of the bearing hole 23 and the components arranged in the bearing hole 23, so that the rotation between the components is smoother, an oil-free inline bearing 231 is provided in the bearing hole 23.

[0035] See also Figure 4As shown, the anti-lock key 3 arranged on the inner side of the main body 2 includes a groove connector 31 arranged at the head, a partition 32 arranged at the waist, and a connection groove 33 arranged at the tail. The groove connector 31 is used to be embedded in the slide, so that the anti-lock key 3 can move left and right in the slide groove 21. The connection groove 33 is used to connect the anti-lock control component of the door lock to control the anti-lock control component. It should be understood that the volume of the connection groove 33 is not necessarily larger than the volume of the groove connector 31. In order to prevent the anti-lock key 3 from being sunk into the slide groove 21 due to its small volume, so that the connection groove 33 is separated from the anti-lock control component and cannot control the door lock to release the anti-lock, a partition 32 with a width greater than the width of the slide groove 21 is provided between the groove connector 31 and the connection groove 33.

[0036] See also Figure 5 As shown, the anti-locking toggle arm 4 disposed below the anti-locking key 3 includes a second connecting hole 41 disposed at the rear end, an upright trapezoidal toggle member 42 disposed on the upper surface of the front end, and an inverted triangular toggle member 43 disposed on the lower surface of the front end. The connecting column 22 is embedded in the second connecting hole 41, so that the anti-locking toggle arm 4 can pivot around the connecting column 22. The trapezoidal toggle member 42 is disposed below the connecting groove 33, and the trapezoidal toggle member 42 pivots upward to move the connecting groove 33 on the waist of the trapezoidal toggle member 42, thereby pushing the anti-locking key 3 to move axially in the sliding groove 21. In this embodiment, the anti-locking key 3 moves to the left to release the anti-locking of the door lock, so the anti-locking key 3 moves to the left under the drive of the trapezoidal toggle member 42. In another embodiment, the anti-locking key 3 moves to the right to release the anti-locking of the door lock, then the installation position of the anti-locking toggle arm 4 and the position of the connecting column 22 need to be mirrored and set on the right side of the waist of the main body 2.

[0037] See also Figure 6 As shown, the L-shaped handle 1 disposed on the outside of the main body 2 includes a linear grip 11 for rotating the handle 1, and a cylindrical first connection hole 12 disposed at the front end of the grip 11. Among them, four linear guide grooves 121 are disposed on the inner wall of the first connection hole 12, which are used to guide the embedding direction of the reset cover 5 and stabilize the connection between the reset cover 5 and the handle 1. A connection slot 122 is disposed in the middle of each guide groove 121.

[0038] See also Figure 7As shown, the head of the reset cover 5 disposed below the anti-locking toggle arm 4 is designed as a quadrangular prism-shaped handle connector 51, wherein a circular arc-shaped external connector 511 is provided on the rear end of the handle connector 51. The reset cover 5 embeds the handle connector 51 into the first connection hole 12 through the bearing hole 23 from the inner side of the main body 2, and the four edges of the side of the handle connector 51 are respectively embedded in the guide groove 121. When the reset cover 5 is embedded in the correct position, the external connector 511 is inserted into the connecting card slot 122, thereby reinforcing the connection between the reset cover 5 and the handle 1. At the same time, the outer diameter of the external connector 511 is smaller than the inner diameter of the internal bearing 231, so that the head of the handle connector 51 can extend out of the bearing hole 23. The waist of the reset cover 5 is designed as an elliptical reset disk 52 with pointed ends, wherein the upper and lower edges of the reset disk 52 are respectively provided with protrusions 521 for connecting the triangular toggle member 43. When the reset disk 52 rotates to make the convex point 521 rotate accordingly, the convex point 521 moves obliquely upward along the edge of the triangular toggle member 43, thereby pushing the anti-lock toggle arm 4 to pivot. The rear of the reset cover 5 is designed as a cylindrical lock core connection boss 53, wherein a coaxial lock core connection groove 54 is provided in the lock core connection boss 53. The lock core connection boss 53 is connected to the lock core through the lock core connection groove 54, thereby driving the lock core structure to rotate to control the extension and retraction of the lock tongue, thereby realizing the opening and closing of the door lock.

The reset cover is rotated by rotating the handle downward, the rotation of the reset disk drives the convex point to rotate to push the anti-lock toggle arm to pivot upward, and the upward movement of the trapezoidal toggle piece pushes the anti-lock key to move along the axial direction of the sliding groove to realize the release of the door lock. The present application sets two protrusions on the reset disk, and the handle can be rotated downward on the left and right sides to drive the anti-lock key to release the door lock. The door lock can be released by rotating the handle from the left or right side, thereby removing the restriction that the door lock needs to be installed from a fixed side, thereby increasing the applicability of the door lock installation.
