Hidden knob, switch and lockset

Abstract

The invention relates to a hidden knob, a switch and a lockset. The hidden knob comprises a handle (1) and a rotating disc (2), the handle (1) is composed of a left handle body (11) and a right handle body (12) which can rotate towards the two sides respectively, the bottoms of the left handle body (11) and the right handle body (12) are fixed to the rotating disc (2), and the tops of the left handle body (11) and the right handle body (12) form a handle after being vertical. And the tops of the left handle body (11) and the right handle body (12) are overturned towards two sides and then attached to the rotating disc (2) to form a plane parallel to the rotating disc (2). And the knob is used for a switch or a lockset. Compared with the prior art, the hidden knob has the advantages of long service life, safety, reliability, wide application range and the like.

Description

technical field [0001] The invention relates to a knob, in particular to a concealed knob, a switch and a lock. Background technique [0002] Knob is a rotary input device that can be operated by grasping and rotating the knob. Knobs are widely used in industrial or household devices, such as knob switches and knob locks, which are used in automobiles, refrigerators, washing machines, etc. . [0003] The knob structure generally includes a handle and a turntable, and a buckle structure and a spring structure can be arranged under the turntable to form a knob switch or a lock. Since the handle is raised on the surface of the turntable, and the height of the handle is about 35mm, this kind of knob switch or lock with convex features is widely used in different fields, and the cost is low and can be recycled and reused, but it has the following defects: [0004] 1) The position will be changed due to the influence of external force, resulting in the attenuation of the switch ...

AI Technical Summary

Problems solved by technology

[0004] 1) The position will be changed due to the influence of external force, resulting in the attenuation of the switch or lock function to failure;

[0005] 2) Affect the overall appearance and consistency;

[0006] 3) There are impacts and obstructions to other objects

[0008] However, the existing hidden knobs similar to the above-mentioned patents are generally complex in structure, and it is difficult to install and use on a surface with a thinner wall thickness.
