Description

Technical Field

[0001] This application relates to the field of door locks, and more specifically, to a handle for a burglarproof lock. Background Technology

[0002] The most common mechanical security door locks currently in use require the key to be turned from the outside to extend the latch (security lock tongue). If a person inside wants to unlock the door, they must also turn the key to retract the latch. Such locks cannot be opened quickly in an emergency.

[0003] To address the aforementioned security risks, some electronic security door locks on the market currently have an electronic button installed on the back panel. Pressing this button activates the internal control circuitry of the lock body, which drives the clutch to engage the handle and the lock core. Only by turning the handle can the lock be opened; otherwise, the clutch will not engage, and the handle will spin freely. However, electronic lock cores have certain limitations and lack the security of mechanical locks. Summary of the Invention

[0004] The purpose of this application is to provide a handle for an anti-theft lock that can solve the technical problems of door locks.

[0005] This application provides a handle for an anti-theft lock, including a handle body, a transmission rod, and a limiting seat. The handle body has a receiving cavity inside, and the limiting seat is installed in the receiving cavity. One end of the transmission rod passes through the limiting seat and extends into the handle body. An arc-shaped guide rail is provided inside the limiting seat, and a steel ball is provided inside the arc-shaped guide rail. An elastic element is provided between the steel ball and the transmission rod. Deformation components are provided at the upper and lower ends of the limiting seat.

[0006] Preferably, the deformation assembly includes a deformation rod and a fixed seat. One end of the deformation rod is fixedly connected to the limiting seat, and the other end of the deformation rod is connected to the fixed seat. The fixed seat is installed in the receiving cavity.

[0007] Preferably, multiple deformation rods are provided, and the multiple deformation rods are symmetrically distributed in the receiving cavity.

[0008] Preferably, the handle body is provided with a positioning post.

[0009] Preferably, at least two positioning posts are provided.

[0010] Preferably, the handle body, the transmission rod, and the limiting seat are all made of metal.

[0011] Preferably, two steel balls and two elastic elements are provided, and the steel balls and the elastic elements are symmetrically distributed at both ends of the transmission rod.

[0012] Preferably, the elastic element is a spring.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a handle for an anti-theft lock, including a handle body, a transmission rod, and a limiting seat. The handle body has an internal receiving cavity, and the limiting seat is installed within the receiving cavity. One end of the transmission rod extends through the limiting seat into the handle body. An arc-shaped guide rail is provided within the limiting seat, and a steel ball is placed within the arc-shaped guide rail. An elastic element is provided between the steel ball and the transmission rod. Deformation components are provided at the upper and lower ends of the limiting seat. In use, the handle body drives the transmission rod to rotate. During rotation, both the elastic element and the deformation components undergo rotational deformation. When rotation stops, the handle body returns to its original position under the force of the elastic element and the deformation components. This utility model is less prone to fatigue deformation, the elastic element and the deformation components are subjected to uniform force, and the handle returns to its original position well.

[0027] like Figure 1-3As shown, a handle for an anti-theft lock includes a handle body 1, a transmission rod 2, and a limiting seat 3. The handle body 1 has an internal receiving cavity 4, and the limiting seat 3 is installed within the receiving cavity 4. One end of the transmission rod 2 extends through the limiting seat 3 into the handle body 1. An arc-shaped guide rail 5 is provided within the limiting seat 3, and a steel ball 6 is disposed within the arc-shaped guide rail 5. An elastic element 7 is disposed between the steel ball 6 and the transmission rod 2. Deformation components 8 are disposed at the upper and lower ends of the limiting seat 3. In use, the handle body 1 drives the transmission rod 2 to rotate. During rotation, both the elastic element 7 and the deformation components 8 undergo rotational deformation. When rotation stops, the handle body 1 returns to its original position under the force of the elastic element 7 and the deformation components 8. This invention is less prone to fatigue deformation, the elastic element 7 and the deformation components 8 are subjected to uniform force, and the handle returns to its original position well.

[0028] In this embodiment, the deformation component 8 includes a deformation rod 9 and a fixed base 10. One end of the deformation rod 9 is fixedly connected to the limiting seat 3, and the other end of the deformation rod 9 is connected to the fixed base 10. The fixed base 10 is installed in the receiving cavity 4. Multiple deformation rods 9 are provided, and the multiple deformation rods 9 are symmetrically distributed in the receiving cavity 4. The deformation rods 9 of this utility model ensure that the two ends of the transmission rod 2 are evenly stressed, which facilitates subsequent reset.

[0029] In this embodiment, the handle body 1 is provided with positioning posts 11. There are at least two positioning posts 11. The present invention has uniform force distribution, good handle reset, and the two positioning posts 11 limit the positioning and are not prone to deformation.

[0030] In this embodiment, in order to extend the service life of the present invention, the handle body 1, the transmission rod 2, and the limiting seat 3 are all made of metal.

[0031] In this embodiment, two steel balls 6 and two elastic elements 7 are provided. The steel balls 6 and the elastic elements 7 are symmetrically distributed at both ends of the transmission rod 2. The elastic element 7 is a spring. Specifically, during the rotation of the transmission rod 2, the spring twists and deforms. The steel balls 6 are squeezed in the arc-shaped guide rail 5, and then the spring returns to its original position under the force of the steel balls 6.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
