The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1 , an embodiment of the present invention provides a knob including a base 1 , an upper cover 2 attached to the base 1 and fixedly coupled thereto, and a ring for rotating the base 1 and the upper cover 2 . Buckle 3, the buckle 3 is hinged to the upper cover 2. When the knob is not required to be turned, the buckle 3 is turned into a position flush with the upper cover 2, so that the knob does not affect the flatness of the surface of the electric appliance or the machine equipment, and the optimal working state of the knob is not affected by the convexity of the knob; When the knob needs to be turned, the buckle 3 is turned to a position perpendicular to the upper cover 2, and the ring 3 can be rotated to drive the overall rotation of the knob.

Specifically, the upper cover 2 is provided with a fastening component for preventing the buckle 3 from shaking. In this way, the buckle 3 is not arbitrarily shaken by the unexpected vibration of the knob, and the electric appliance or the machine equipment using the knob does not cause the buckle 3 to be turned outward due to its own movement or vibration, thereby affecting the appearance of the electric appliance or the machine, and at the same time It can also prevent the buckle 3 from being pulled out and being subjected to an unexpected force to break.

As a preferred embodiment of the present invention, the upper cover 2 is provided with a receiving slot 21, and the securing assembly includes a spring 4 disposed in the receiving slot 21 and two sets of resisting members 5 respectively located at the ends of the spring 4. Each of the set of resisting elements 5 includes a first rotating shaft 51 and a second rotating shaft 52. One end of the first rotating shaft 51 has a first concave-convex surface 511, and one end of the second rotating shaft 52 has a second concave-convex surface 521, and the first concave-convex surface 511 and The second concave-convex surface 521 is engaged, the other end of the first rotating shaft 51 is fixedly coupled to the buckle 3, and the other end of the second rotating shaft 52 is inserted into one end of the spring 4. Referring to FIG. 2 to FIG. 4, since the first concave-convex surface 511 and the second uneven surface 521 are undulating and uneven, the convex and concave portions of the two are complementaryly fitted, and the concave and convex surfaces serve to hinder the relative rotation of the two rotating shafts. The effect is that only when the buckle 3 is subjected to a certain outwardly flipping force, the first rotating shaft 51 will overcome the resistance between the concave and convex surfaces and rotate accordingly. The position at which the protrusion of the first rotating shaft 51 to the concave-convex surface is opposite to the protrusion of the concave-convex surface of the second rotating shaft 52 is a critical point. It can be understood that the buckle 3 can be turned over when the first rotating shaft 51 rotates beyond the critical point. To the position perpendicular to the upper cover 2, and beyond the critical point, the buckle 3 will automatically turn to the position perpendicular to the upper cover 2 (ie, the ring If the first rotating shaft 51 does not rotate beyond the above critical point, the external force will be automatically restored to the position flat with the upper cover 2 (see Fig. 2). The technical effect of the concave-convex structure is that even if the knob is subjected to an unexpected micro-vibration, the buckle 3 will not be automatically turned outwards without affecting the normal flipping of the buckle 3, and the buckle 3 can be flipped by applying an appropriate force. . The above-mentioned uneven surface is respectively provided with four protrusions and four recesses. When the buckle 3 is turned 45°, the protrusion of the first rotating shaft 51 to the concave-convex surface thereof is opposite to the convex surface of the concave surface of the second rotating shaft 52. (See Figure 3), the critical state. It should be noted that the number of protrusions and depressions may be set to different numbers according to requirements. In this case, there are a plurality of the above-mentioned critical points, and the first rotation shaft 51 needs to rotate all the critical points to make the buckle 3 flip to the upper cover 2 Vertical position or position flat with the upper cover 2.

Specifically, the first uneven surface 511 and the second uneven surface 521 may be a smoothly curved curved surface or a meandering flat surface. It is understood that the concave-convex surface shape may be provided as long as it prevents the relative rotation between the rotating shafts.

Further, the buckle 3 includes a "C"-shaped body and two insertion shafts 31 projecting from opposite ends of the body. The insertion shaft 31 is provided with a stop surface 311, and the other end of the first rotation shaft 51 is provided with a plug. The insertion hole 211 of the shaft 31 is provided with a through hole 211 through which the insertion shaft 31 passes, and each insertion shaft 31 passes through the through hole 211 and is inserted into the insertion hole 512. In this way, the loading and unloading of the fastening component is very convenient, and the loading and unloading buckle 3 is also convenient.

Specifically, the shaft of the second rotating shaft 52 is provided with an anti-rotation edge 522 for preventing the rotation of the second rotating shaft 52 in the accommodating groove 21, and the anti-rotation edge 522 is engaged with the accommodating groove 21. When the first rotating shaft 51 rotates, the second rotating shaft 52 will be subjected to a reaction force due to the obstruction between the concave and convex surfaces, so that the second rotating shaft 52 has a tendency to rotate with it, and the anti-rotation edge 522 is disposed to prevent the second The rotation shaft 52 acts as it rotates.

Specifically, the other end of the second rotating shaft 52 is provided with a convex shaft 523, and the protruding shaft 523 is inserted into the spring 4. In this way, not only can the assembly of the second shaft 52 and the spring 4 be made easier, but also the misalignment of the two can be prevented.

The knob provided by the embodiment of the present invention further includes a filling strip 6 for preventing debris from falling into the knob. Since the insertion shaft 31 of the buckle 3 is inserted into the upper cover 2 from the side wall, it can be seen that the buckle 3 surrounds one side of the upper cover 2. At this time, there is a groove on the other side of the upper cover 2, and if the groove is not filled, debris may easily fall into it. The filling strip 6 serves to fill the groove. The upper cover 2 and the filling strip 6 can be fixedly mounted on the base 1 by bolts, which facilitates the assembly of the knob as a whole.

Referring to Fig. 5, an embodiment of the present invention further provides a massager 7 using the above knob. The massager using the knob provided by the present invention does not affect the comfort of use, and the user barely feels the existence of the knob. When adjusting the knob, it is only necessary to manually lift the flip ring 3 to make it perpendicular to the upper cover 2, and rotate the buckle 3 to adjust the knob.

The above is only the preferred embodiment of the present invention and is not intended to limit the present invention.
