Description

Technical Field

[0001] The utility model relates to the field of speed knobs, in particular to a speed knob with a gear position prompting structure. Background Art

[0002] The knob is a manual component that is turned by hand. According to the functional requirements, it can be divided into continuous multiple rotations, with a rotation angle of up to 360°; it can also be used for positioning rotation, etc. Its shape can be classified into (a) circular knob, (b) polygonal knob, (c) pointer knob, (d) manual dial, etc.

[0003] Many devices use knobs as speed adjustment structures, which are convenient to use. Different speed level marking lines are usually printed on the surface of the equipment. The speed knob can be accurately adjusted according to the position of the marking lines. However, for some sites with poor working environments, the surface of the equipment is easily stained with oil and dust, which will directly cover the marking lines on the surface of the equipment. Therefore, the position of the speed knob indication cannot be directly observed. For old employees, they have been using it for a long time and can remember the corresponding position by themselves. However, for new employees, in the absence of marking line indications, it is easy to make wrong operations, which will lead to adverse consequences.

[0004] Therefore, it is necessary to provide a new speed knob with a gear position prompt structure to solve the above technical problems. Utility Model Content

[0009] Several of the indicator lights are connected in parallel to the circuit to which the speed knob belongs, and the broadcasting speaker is connected in series to the circuit to which the speed knob belongs. The circuit to which the speed knob belongs can be controllably connected to form a path with any indicator light, and any indicator light corresponds to an audio frequency of the broadcasting speaker.

[0010] Preferably, an embedding groove is further provided at the upper end of the twist plate, and a plurality of indicator lights are equidistantly distributed and fixed in an embedded manner at the bottom of the embedding groove.

[0011] Preferably, a transparent plastic plate is placed inside the embedding groove, and a fixing bolt penetrates through the plastic plate near the end thereof, and the fixing bolt extends into the interior of the torsion plate and forms a threaded connection therewith.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 3The speed knob with a gear prompt structure provided by the embodiment of the utility model comprises a speed knob, which comprises a turntable 1 and a twist plate 2 embedded in the upper end of the turntable 1, and a plurality of indicator lights 4 emitting different colors and a broadcasting speaker 7 capable of emitting different audio frequencies are also installed inside the twist plate 2;

[0023] Among them, a contact switch 9 is also fixed on the speed knob, and the contact switch 9 forms a path with the circuit belonging to any indicator light 4 by rotating, and several indicator lights 4 are connected in parallel to the circuit belonging to the speed knob, and the broadcasting speaker 7 is connected in series to the circuit belonging to the speed knob. The circuit belonging to the speed knob can form a path with any indicator light 4 in a controllable manner, and any indicator light 4 corresponds to a single audio frequency of the broadcasting speaker 7.

[0024] It should be noted that the indicator light 4 provided in the speed knob can emit indicator lights of different colors, so the operator can know the speed level corresponding to the speed knob according to the color of the light, thereby adjusting the equipment;

[0025] It should also be noted that the broadcasting speaker 7 can emit different audios, and the types of audios correspond to the different colors of light of the indicator light 4, so it can not only provide the operator with corresponding information visually, but also play an auxiliary role in hearing, so as to ensure that the operator can accurately adjust the speed torque;

[0026] It should also be noted that the contact switch 9 in the device forms a path with one of the indicator lights 4 at one time, and the indicator light 4 that does not form a path is in a power-off state, thereby achieving a single correspondence and a better indication effect.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The upper end of the torsion plate 2 is also provided with an embedding groove 3, and a plurality of indicator lights 4 are evenly distributed and embedded in the bottom of the embedding groove 3;

[0028] At the same time, a transparent plastic plate 5 is placed inside the embedding groove 3, and a fixing bolt 6 penetrates the plastic plate 5 near the end thereof. The fixing bolt 6 extends into the interior of the torsion plate 2 and forms a threaded connection therewith.

[0029] It should be noted that the plastic plate 5 arranged inside the embedding groove 3 for installing the indicator light 4 is a transparent material, so the light emitted by the indicator light 4 can directly penetrate the plastic plate 5, so that the operator can see the color of the light more clearly. At the same time, the plastic plate 5 can also protect the indicator light 4 from being hit by foreign objects.

[0030] In the embodiments of the present invention, please refer to Figure 1 and Figure 2A cavity is added inside the twisting plate 2, and the broadcasting speaker 7 is fixed inside the cavity. A sound hole 8 is also opened at the upper end of the twisting plate 2, and the sound hole 8 is connected to the cavity.

[0031] It should be noted that the broadcasting speaker 7 is installed inside the twist plate 2, so it is more fully protected, and the additional sound hole 8 can be used for sound to be transmitted to the outside, so that the operator can hear the sound clearly.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
