Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, in particular to a knob, and more particularly to a knob structure. Background Art
[0002] A knob is a commonly used part in the fields of machinery and electricity and is used to drive the rotation of an input shaft connected coaxially. In the prior art, during use of some knobs, slippage easily occurs between the knob and the input shaft, which is not conducive to accurately inputting signals. Content of the Utility Model
[0003] The purpose of the utility model is to provide a knob structure, and this knob structure is to solve the technical problem that slippage easily occurs during use of some knobs in the prior art.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A knob structure includes an insulating cap body and a core body; the cap body is cylindrical, and a plurality of anti-slip ribs are arranged on the surface of the upper part of the cap body along the circumferential direction, the anti-slip ribs are parallel to the axial direction of the cap body, and a cavity with an opening downward is coaxially arranged inside the lower end surface of the cap body; a first convex ring is arranged on the middle part of the core body along the circumferential direction, a second convex ring is arranged on the lower part of the core body along the circumferential direction, the outer edges of the first convex ring and the second convex ring are both continuous tooth-shaped, and a screw hole is coaxially arranged inside the lower end surface of the core body; the core body is coaxially arranged in the cavity.
[0006] Further, chamfers are arranged on the upper side surface of the first convex ring, the upper side surface of the second convex ring, and the inner side surface of the lower port of the cavity.
[0007] Working Principle:
[0008] The knob of the utility model is composed of a cap body and a core body. A screw hole is arranged on the lower end surface of the middle part of the core body for connecting a control rod. The core body is riveted into the cap body by a cold riveting method. The first convex ring and the second convex ring on the outer surface of the core body adopt a tooth-shaped structure, effectively preventing the phenomenon that the core body rotates in the cap body after riveting.
[0009] Compared with the prior art, the beneficial effect of the utility model is that: through the convex rings with a tooth-shaped structure on the surface of the core body, the rotation of the core body in the cap body is prevented, realizing the functions of anti-rotation and anti-slip.

[0012] Embodiment 1
[0013] Please refer to Figure 1 、 Figure 2 The present utility model provides a technical solution:
[0014] A knob structure includes an insulating cap body 1 and a core body 2; the cap body 1 is cylindrical, and a plurality of anti-slip rib strips 11 are arranged on the upper surface of the cap body 1 along the circumferential direction, and the anti-slip rib strips 11 are parallel to the axial direction of the cap body 1. An accommodation cavity 12 with an opening downward is coaxially arranged inside the lower end surface of the cap body 1; a first convex ring 21 is arranged on the middle part of the core body 2 along the circumferential direction, and a second convex ring 22 is arranged on the lower part of the core body 2 along the circumferential direction. The outer edges of the first convex ring 21 and the second convex ring 22 are both continuous tooth-shaped, and a threaded hole 23 is coaxially arranged inside the lower end surface of the core body 2; the core body 2 is coaxially arranged in the accommodation cavity 12.
[0015] Furthermore, chamfers are arranged on the upper side surface of the first convex ring 21, the upper side surface of the second convex ring 22, and the inner side surface of the lower port of the accommodation cavity 12.
[0016] Working process:
[0017] The core body 2 is riveted into the cap body 1 by a cold riveting method, and then the threaded hole 23 is threadedly connected with the input shaft of the device to be used.
[0018] The anti-slip rib strips 11 on the surface of the cap body 1 can not only prevent slipping but also enhance the strength of the cap body 1.
[0019] Chamfers are arranged on the upper side surface of the first convex ring 21, the upper side surface of the second convex ring 22, and the inner side surface of the lower port of the accommodation cavity 12, which can play a guiding role during the riveting process of the core body 2.
[0020] A barb structure is formed at the lower end of the first convex ring 21 relative to the accommodation cavity 12. After the riveting is completed, it can prevent the core body 2 from axially disengaging from the accommodation cavity 12.
