Description

Warning pilot lamp illumination button structure

Technical Field

The utility model relates to an alarm indication illumination button, in particular to, alarm indication lamp illumination button structure.

Background

The alarm indication lighting key is one of the core components of the weapon operation device, and the effective display of the alarm indication lighting key plays an important role in improving the weapon operation capability.

The existing warning indication lighting key mainly uses an entity key as a display unit and is structurally limited by a typical key structure, so that the warning indication lighting on the surface of the key is uneven, the rapid identification rate is low, and along with the improvement of the fighting requirement, the rapid identified performance of the fighting equipment is improved, and the key has extremely important significance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the inhomogeneous problem of button illumination among the prior art, and provide a neotype warning indicator illumination button structure.

In order to realize the purpose, the technical scheme of the utility model is as follows: an illumination key structure of an alarm indicating lamp comprises,

the key body is provided with a body bottom wall and a body peripheral wall, the body bottom wall and the body peripheral wall jointly define a stepped blind hole with an upward opening, the stepped blind hole consists of a blind hole upper step and a blind hole lower step, the inner diameter of the blind hole upper step is larger than that of the blind hole lower step, and a ventilation through hole communicated with the blind hole lower step is formed in the body bottom wall;

a cover body disposed on the blind hole upper step, the cover body sealing the blind hole lower step; and the number of the first and second groups,

a dispersion medium disposed at a lower step of the blind hole;

wherein, the body diapire adopts the printing opacity material.

As a preferred scheme of the key structure illuminated by the alarm indicator lamp, the dispersion medium is air.

Compared with the prior art, the beneficial effects of the utility model reside in at least: 1. the key body filled with dispersion medium inside replaces the existing solid key; 2. the effect of uniform illumination can be effectively achieved through the dispersion medium; 3. the air holes are used for balancing the pressure difference between the inside and the outside.

Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 2, an alarm indicator light illumination key structure is shown, which can be used for a control panel of a weapon system such as aviation, aerospace, shipboard, weapons, and the like.

The key structure mainly comprises a key body 1, a seal cover body 2, a dispersion medium 3 and the like.

The key body 1 has a body bottom wall 11 and a body peripheral wall 12. The bottom wall 11 of the body is a plate-shaped structure. The body peripheral wall 12 extends upward from the top surface of the body bottom wall 11. The peripheral wall 12 of the body is of an annular structure. The body bottom wall 11 and the body peripheral wall 12 together define a stepped blind hole 120 with an upward opening. The stepped blind hole 120 is composed of a blind hole upper step 1201 and a blind hole lower step 1202. The inner diameter of the blind hole upper step 1201 is larger than the inner diameter of the blind hole lower step 1202. The bottom wall 11 of the body is formed with a ventilation through hole 110 communicated with the lower step 1202 of the blind hole. By using the ventilation through hole 110, the pressure difference between the inside of the blind hole lower step 1202 and the outside of the key body 1, which is generated under various industrial control conditions, can be balanced.

The closure body 2 is placed on the blind hole upper step 1201. The cover body 2 covers the blind hole lower step 1202. The closure body 2 is imprinted with light-transmitting characters or indicia 20.

The dispersion medium 3 is placed in the blind hole lower step 1202. The dispersion medium 3 includes, but is not limited to, various types of dispersion tablets, colloids, air. And dispersing incident light by using the dispersion medium 3 to achieve the purpose of uniform illumination.

The principle of the key structure is as follows: the bottom wall 11 of the body is made into a light-transmitting surface, so that light enters the stepped blind hole 120. After the light passes through the dispersion medium 3 uniformly, the alarm information to be expressed is displayed through the display characters or the marks.

The above description is only intended to illustrate embodiments of the present invention, and the description is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
