Description

Technical Field

[0001] The utility model relates to the technical field of lamp design and manufacturing, in particular to a lamp structure of a fire sign lamp. Background Art

[0002] Fire sign lamps are generally used in various buildings, tunnels and other scenarios. Their display surfaces are generally rectangular and are provided with arrow patterns for direction indication and various fire schematic diagrams. In existing fire sign lamps, the sizes of the lamp boards of the sign lamps and the outer shells need to correspond one by one. For example, a fire safety passage indicator lamp authorized and announced on October 11, 2022 with the Chinese patent authorization announcement number CN217562220U includes a maintenance shell and an indicator lamp board arranged on the front side of the maintenance shell. An installation mechanism is arranged between the maintenance shell and the indicator lamp board, and a heat dissipation mechanism is arranged inside the maintenance shell. The installation mechanism includes a slide bar, a sliding sleeve, a return spring, a clamping rod and a clamping sleeve. The slide bar is fixedly connected to the inner side wall of the maintenance shell. The heat dissipation mechanism includes a heat conducting member and a heat conducting column. The heat conducting member is in a rectangular frame structure and is fixedly arranged inside the maintenance shell. The sizes of its maintenance shell and the indicator lamp board correspond. When the size of the indicator lamp board is smaller than that of the maintenance shell, loosening is likely to occur after installation. Content of the Utility Model

It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0021] Referring to Figures 1-4 As shown, a structure of a fire sign lamp includes an aluminum profile frame 1, a light-emitting component 2 and an indicator lamp board 3. The aluminum profile frame 1 and the indicator lamp board 3 form a cavity, and the light-emitting component 2 is arranged in the cavity. The light-emitting component 2 has a power line connected to an external power supply. The aluminum profile frame 1 includes a first substrate 4 and at least two first side plates 5. The first side plates 5 are perpendicular to the first substrate 4. Inner positioning protrusions 6 are arranged on the inner sides of the first side plates 5. Outer positioning protrusions 7, first positioning depressions 8, second positioning depressions 9, third positioning depressions 10, fourth positioning depressions 11 and limit protrusions 16 are sequentially arranged on the outer sides of the first side plates 5 from the end far from the first substrate 4 to the end close to the first substrate 4. Lamp board positioning protrusions 17 are arranged on the indicator lamp board 3, and the lamp board positioning protrusions 17 correspond to the shapes of the first positioning depression 8 or the second positioning depression 9 or the third positioning depression 10 or the fourth positioning depression 11. The sizes of the first positioning depression 8, the second positioning depression 9, the third positioning depression 10 and the fourth positioning depression 11 are all the same. The first substrate 4 is 25 cm wide and 2 cm high; the first side plates 5 are 1 cm wide and 8 cm high; the inner positioning protrusions 6 are 2 cm away from the first substrate 4, mainly for positioning the light-emitting component 2 in the cavity. The outer positioning protrusions 7 and the limit protrusions 16 are mainly used to indicate the installation range of the indicator lamp board 3 to prevent the indicator lamp board 3 from exceeding the predetermined installation range during installation and causing skewness and other situations. In the attached Figure 3 In the aluminum profile frame 1, the two first side plates 5 are symmetric left and right. A back plate is installed on the left side, and the indicator lamp board 3 is installed on the right side.

[0022] A light-transmitting part 12 in the shape of a safety exit pattern is arranged on the indicator lamp board 3.

[0023] A clamping plate 13 is also arranged on the aluminum profile frame 1. The cross-section of the clamping plate 13 is U-shaped. The two sides of the clamping plate 13 are correspondingly installed on the indicator lamp board 3 on one side of the aluminum profile frame 1 and the back plate installed on the other side of the aluminum profile frame 1. The clamping plate 13 is used to clamp the indicator lamp board 3 and the back plate on the aluminum profile frame 1. The inner width of the clamping plate 13 is slightly smaller than the width of the first substrate 4, and the length of the substrate depends on the installation requirements. Friction areas 14 are arranged on the outer sides of the two sides of the clamping plate 13. The friction areas 14 are composed of a number of staggered protrusions or depressions. In the attached Figure 1 In order to show the outline of the aluminum profile frame 1, the clamping plate 13 is omitted.

[0024] During use, first place the indicator light panel 3 against the first side plate 5, and make the positioning protrusion 17 of the light panel embed into the corresponding recess according to the size of the indicator light panel 3. Then snap the clamping plate 13 onto the aluminum alloy profile frame 1 to press the indicator light panel 3 tightly against the first side plate 5 to complete the installation.

All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
