Description

Technical Field

[0001] The invention mainly relates to the technical field of luminous knobs, and in particular to a luminous knob that can be reliably installed. Background Art

[0002] At present, there is no structural design for the key light guide plate to reinforce the illuminated knob. The illuminated knob is generally made of plastic. For the key light guide plate where the knob needs to be illuminated, the most difficult problem to deal with is the problem of fixing the knob with the luminous material. The current common design idea for the illuminated knob is to insert a wire screw sleeve in the fixing hole of the illuminated knob. Such a design will cause the illuminated knob to be too large. If the design is unreasonable, it will also cause the knob to crack and the gap between the knob and the panel to fluctuate during rotation. Similarly, simple reinforcement methods often cannot solve the problem of the knob. In the face of extremely harsh environments, the reliability of the knob cannot be guaranteed.

[0003] In important locations or military fields, the use environment of light-emitting knobs on key light guide plates is relatively harsh, and the fixing method of light-emitting knobs directly affects the reliability of military systems. In military key light guide plate products, knobs often need to be debugged, and the design of the knobs must be convenient for installation, disassembly and debugging, and at the same time, the structure must be simple, reliable, and easy to process.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Summary of the invention

[0011] 3. Beneficial effects: Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention has a reasonable design, a simple structure and a low processing cost. In a high-intensity vibration environment, most of the impact force will be absorbed by the internal insert block, so the outer knob shell is not easily damaged, thereby reducing the risk of cracking on the entire luminous knob; the structural cost is saved, and it is connected to the operating table button through multiple locking screws, which is more reliable, more practical, and easy to disassemble and maintain.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and can adopt the existing technologies known to those skilled in the art. Example

[0020] See attached Figure 1-3 , a reliably mounted illuminated knob comprising A knob housing 1, wherein a first connecting hole 2 is formed on one side of the knob housing 1, a receiving space 3 is formed on the inner side of the bottom of the knob housing 1, and a light-emitting block 4 is formed on the knob housing 1; An insert block 5 is arranged in the accommodating space 3, and a first threaded hole 6 is opened at a corresponding position of the insert block 5, and the first threaded hole 6 and the first connecting hole 2 are in a straight line. A device mounting hole 7 is opened in the middle of the insert block 5, and the first connecting hole 2 is matched with the first threaded hole 6 through a first locking screw; when the present device is used, the insert block 5 is first placed in the accommodating space 3, and then the device mounting hole 7 is aligned with the rotary button on the operation panel and inserted, and the first connecting hole 2 and the first threaded hole 6 are inserted through the first locking screw, and the first threaded hole 6 is threadedly connected with the hole on the side of the rotary button, so that the entire knob housing 1 can be combined with the rotary button. When in use, the knob housing 1 is rotated to perform a rotating operation, and the force generated during rotation is mainly applied to the insert block 5, thereby increasing the service life of the knob housing 1.

[0021] The knob housing 1 is a convex structure, which is convenient for users to perform rotation operations.

[0022] The other two sides of the knob housing 1 are symmetrically provided with second connecting holes 11, and the corresponding positions of the insert block 5 are provided with second threaded holes 12. The second connecting holes 11 are matched with the second threaded holes 12 to be connected with second locking screws. If the rotating button of the device mounting hole 7 is fixed only by the locking screws in the first threaded hole 6, the actual machining of the relevant materials will be different from the model, and it will be difficult to make the machined device mounting hole 7 and the rotating button fit completely, which will cause a gap between the rotating button and the device mounting hole 7. When there is only one screw to limit the rotating button, the guide column knob housing 1 will be unevenly stressed and will tilt toward the screw side. In order to further improve the stability of the knob housing 1 during rotation, in this embodiment, the rotating button is additionally fixed by two second locking screws.

[0023] The insert block 5 is made of aluminum alloy or stainless steel, which has high stability, thereby increasing the service life of the entire device.

[0024] A sawtooth structure 51 is distributed in an annular manner on the outer side of the insert block 5, and the outer diameter of the sawtooth structure 51 is larger than the diameter of the accommodating cavity. The insert block 5 is connected to the accommodating space 3 by hot pressing. When installing the insert block 5, the sawtooth structure 51 is heated, and then the entire insert block 5 is inserted into the accommodating cavity of the knob housing 1 to complete the hot pressing. The sawtooth structure 51 can increase the contact area between the insert block 5 and the accommodating space 3, thereby improving the reliability.

[0025] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
