Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locks, and in particular to a handle locking structure of a swing door lock. Background Art
[0002] In existing indoor swing door lock designs, the locking mechanism is typically located to the side or below the door handle, using a split twist mechanism to achieve the door's reverse locking function. This traditional locking mechanism requires the user to rotate a separate locking component located next to the handle to activate the internal deadbolt, thereby reverse locking the door. While this design meets basic security requirements to a certain extent, its inherent structural characteristics also bring a series of problems.
[0003] First, the separation of the locking structure from the door lock increases the number of components in the entire lock system, which not only increases manufacturing costs but also makes the lock bulky, which is not conducive to the pursuit of minimalist aesthetics and space utilization in modern homes. Second, during long-term use, users frequently twist the locking components, which can easily cause mechanical wear on the components and their connections. Over time, this wear accumulates and may eventually cause the locking structure to loosen or even fail, seriously affecting the stability and security of the door lock. Currently, no effective solution has been proposed to address these problems in the related art. Utility Model Content
[0004] In view of the problems in the related art, the present invention proposes a handle locking structure for a swing door lock to overcome the above technical problems existing in the existing related art.
[0005] To this end, the specific technical solutions adopted in this utility model are as follows:
[0006] A handle locking structure for a swing door lock comprises two metal rectangular support plates, a lock core is rotatably mounted on the support plates, an adjusting shaft is rotatably mounted inside the lock core through the support plates, both ends of the adjusting shaft are threadedly connected to a telescopic ring, both sides of the surface of the telescopic ring are fixedly connected to a support frame, the end of the support frame is fixedly connected to a positioning column, limiting holes are provided on both sides of the support plates, a rotary handle 1 is fixedly mounted on one side of the lock core, and a rotary handle 2 is fixedly mounted on the other side, a toggle block is slidably mounted inside the rotary handle 1, one side of the toggle block is fixedly connected to a transmission rack, a transmission column is rotatably mounted on one side of the rotary handle 1 and the rotary handle 2, one end of the transmission column is fixedly connected to a transmission gear, connecting grooves are provided at both ends of the adjusting shaft, a sliding groove is provided on one side of the rotary handle 1, and one side of the toggle block is slidably mounted in the sliding groove.
[0007] Furthermore, in order to protect the internal structure of the rotary handle 1 and the rotary handle 2, a positioning block is fixedly connected to the inside of the rotary handle 1 and the rotary handle 2, and an adsorption groove is provided on the surface of the positioning block. A protective plate is slidably installed on one side of the rotary handle 1 and the rotary handle 2, and a magnetic block is fixedly installed on one side of the protective plate and the adsorption groove.
[0008] Furthermore, in order to adjust and unlock the locking structure when it is accidentally locked, one end of the internal transmission column of the rotary handle is fixedly connected to a twisting column, and a twisting groove is opened on the surface of the twisting column, and the thickness of the protective plate matches the twisting groove.
[0009] Furthermore, in order to facilitate the fixed installation of the rotary handle 1 and the rotary handle 2 on the lock core, threaded holes are opened on both sides of the surface of the lock core, and positioning holes are opened on both sides of the interior of the rotary handle 1 and the rotary handle 2.
[0010] Furthermore, in order to limit the rotation of the positioning column and the lock core, the positioning column cooperates with the limiting hole, and the end of the transmission column cooperates with the connecting groove.
[0011] Furthermore, in order to enable the transmission gear to drive the transmission rack to rotate in the rotary handle, the transmission gear is meshed and connected with the transmission rack.
[0012] Furthermore, in order to protect the first and second rotary handles when they are turned, rubber protective pads are provided on both sides of the surfaces of the first and second rotary handles.
[0013] The beneficial effects of the present invention are as follows: the transmission rack drives the transmission gear and the adjusting shaft to rotate by sliding the toggle block in the rotating handle, and the rotating adjusting shaft drives the positioning column to move into the limiting hole, thereby limiting the rotation of the lock cylinder and the two handles, and thus achieving the locking effect. The structure is locked by toggling the toggle block, and the locking method is simple and fast, which reduces the difficulty and fatigue of operation and greatly improves the user experience. The locking structure and the handle are integrated in the way that the volume is also reduced accordingly, which effectively improves the aesthetics of the lock. In addition, the toggle locking method reduces the mechanical wear and loosening problems caused by long-term operation, which greatly extends the service life of the lock and reduces maintenance costs.
