TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mine lamp, especially relates to a safety type information mine lamp alarm button cap mounting structure. BACKGROUND

[0002] The mine lamp is the short name of mine lamp or industrial and mining lamp, and is the general name of special lighting lamps used in mines. The safety type information mine lamp is also called intrinsically safe mine lamp, and is suitable for places with gas (methane group) and coal dust explosion hazards in coal mine: well bottom mining area tunnel, and can also be used in mine tunnel and chamber with more water. Main use: used for safe lighting, emergency rescue lighting in mine, petroleum, chemical industry and other environments with flammable and explosive combustible gas, especially suitable for coal mine, tunnel and various underground engineering, civil air defense engineering.

[0003] The traditional mine lamp is only an underground lighting tool, and the safety type information mine lamp places the positioning card in the mine lamp battery box to realize two-in-one of personnel positioning and mine lamp lighting, realizes the lighting of underground miners and the accurate positioning of personnel, and is very suitable for the requirements of mine informatization construction.

[0004] According to the relevant regulations of coal safety, the positioning card must have a one-key alarm button to facilitate underground personnel to report the position information when encountering an emergency.

[0005] The existing alarm button mounting structure has the following defects:

[0006] 1. The button cap is usually higher than the surface of the battery shell, is easily extruded by the outside and collided with foreign matters to cause misoperation, causes frequent uploading of alarm information, causes misjudgment of the positioning system, and causes unnecessary trouble to production management;

[0007] 2. The button cap mounting hole is too small, is inconvenient to press with fingers, and cannot report the help signal in time when an emergency occurs. INVENTION CONTENTS

[0008] Therefore, in view of the above technical problems, a safety type information mine lamp alarm button cap mounting structure is provided.

[0009] The technical scheme adopted by the utility model is as follows:

[0010] A safety type information mine lamp alarm button cap mounting structure, comprising a vertical mounting hole formed in the top of a mine lamp battery box and a button cap arranged in the mounting hole, wherein the button cap is connected with an alarm button located inside the mounting hole, and the opening diameter of the mounting hole is greater than the outer diameter of the button cap, the horizontal distance between the two is (D / 2) ± 0.1mm, D represents the outer diameter of the button cap, and the top of the button cap is flush with the opening of the mounting hole.

[0011] The utility model discloses a convenient finger pressing, and the possibility of being misoperated can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0012] The utility model will be explained in detail below in combination with the drawings and specific embodiment:

[0013] Figure 1 It is the structure diagram of the utility model;

[0014] Figure 2 It is Figure 1 A-A section view of the utility model;

[0015] Figure 3 It is Figure 2 B-B section view of the utility model;

[0016] Figure 4 It is Figure 2 The partial enlarged view of the utility model. DETAILED DESCRIPTION

[0017] As Figure 1 The utility model discloses a kind of installation structures of intrinsically safe type information miner lamp alarm button cap, including vertical installation hole 110 and button cap 120.

[0018] Vertical installation hole 110 is formed in the top of miner lamp battery box 2, its cross section is circular, including lower hole section 111 and the upper hole section 112 connected with lower hole section 111, lower hole section 111 is straight hole (vertical section is rectangle), the vertical section of upper hole section 112 is inverted trapezoidal, see Figure 2 And Figure 4 .

[0019] In the embodiment, the hole wall of upper hole section 112 is 120 ° angle with the hole wall of lower hole section 111.

[0020] Button cap 120 adopts silica gel material, cross section is circular, it is integrally formed on indicating lamp cover 21 of miner lamp battery box 2, see Figures 2-4 Wherein, indicating lamp cover 21 is used to protect internal positioning card, simultaneously, its material is also silica gel material and can be light-transmitting (such as adopting white silica gel material), facilitate LED three-color indicating lamp on positioning card indicating the working state of positioning card.

[0021] Button cap 120 is concentrically arranged in installation hole 110, and is connected with alarm button 3 male and female joint located in installation hole 110 inside.

[0022] The opening caliber of the mounting hole 110 is greater than the outer diameter of the key cap 120, and the horizontal distance between the two is (D / 2)±0.1mm, which facilitates finger pressing, and in case of emergency, the signal for help can be reported in time, and the upper hole section 112 is designed as an inverted trapezoid (wide at the top and narrow at the bottom), which increases the contact surface and flexibility of pressing the key cap 120 by fingers, and further improves the operability of the alarm key. At the same time, the top of the key cap 120 is flush with the opening of the mounting hole 110, so that the key cap 120 is not easily pressed by external forces and collided by foreign matters, reducing the possibility of being misoperated, reducing the risk of invalid alarm caused by misoperation, and greatly improving the production management efficiency.

[0023] In the present embodiment, D=5-10mm.

[0024] It can be understood that the cross section of the mounting hole 110 and the key cap 120 can not be circular, and the two can be eccentrically arranged, and in one possible implementation, the lower hole section 111 and the upper hole section 112 of the mounting hole 110 can both be straight holes.

[0025] As can be seen from the above, the application provides an installation structure of an alarm key cap of an intrinsically safe information mining lamp, which is convenient for finger pressing and can reduce the possibility of being misoperated.

[0026] However, those skilled in the art in the technical field should realize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application, as long as the changes and modifications of the above described embodiments are within the scope of the present application, the changes and modifications of the above described embodiments will fall within the scope of the claims of the present application.
