Description

Technical Field

[0001] The utility model relates to the technical field of knobs, in particular to a quick-installation knob. Background Art

[0002] A knob is a common mechanical component, usually circular, with protrusions or textures on the periphery for easy manual operation. Generally, it is used to adjust or control the parameters or functions of a device, instrument or system by rotation. The uses of knobs are very extensive. In electronic devices, such as radios and stereos, knobs can be used to adjust volume, frequency band, tone, etc. On household appliances such as stoves and ovens, knobs can control the size of the fire and the height of the temperature. Inside a car, functions such as air-conditioning temperature, wind speed, audio volume, and seat adjustment are also often operated by knobs. In industrial instruments and mechanical equipment, knobs can be used to adjust parameters such as pressure, speed, and flow rate.

[0003] Generally, there is a bushing inside a knob, which matches the shaft rod on the device. Align the bushing with the shaft rod and insert it, and then fix the knob on the shaft rod with screws, snap rings or other fixing parts. This installation method is not convenient enough. Therefore, those skilled in the art propose a quick-installation knob to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a quick-installation knob, aiming to improve the problem that in the prior art, the bushing inside the knob matches the shaft rod on the device, align the bushing with the shaft rod and insert it, and then fix the knob on the shaft rod with screws, snap rings or other fixing parts, and the installation method is not convenient enough.

[0005] To achieve the above object, the utility model provides the following technical solution: A quick-installation knob, including a knob body, a rotating handle is arranged inside the knob body, a threaded body is fixedly connected to the outer circle of the knob body, a chrome-plated plastic front ring is sleeved outside the knob body, a threaded groove is opened inside the chrome-plated plastic front ring, a threaded ring is arranged on the outer circle of the knob body, and a tightening nut is sleeved outside the knob body.

[0006] Further, the outer circle of the threaded body is threadedly connected to the threaded groove.

[0007] Further, the inner circle of the tightening nut is threadedly connected to the outer circle of the threaded ring.

[0008] Further, a communicating vessel is arranged inside the knob body.

[0009] Further, one end of the communicating vessel is electrically connected to the bottom of the rotating handle.

[0010] The utility model has the following beneficial effects:

[0011] 1. In the present utility model, by inserting the knob body into the installation hole on the equipment panel to be assembled and then tightening the compression nut in threaded cooperation, this installation is convenient, relatively fast and stable.

[0012] 2. In the present utility model, by rotating the rotating handle, the internal connecting piece can be made to change its position, so as to be connected to different ports of the communicating vessel, realizing different electrical paths. BRIEF DESCRIPTION OF THE DRAWINGS
