Problems solved by technology

[0002] Explosion-proof lamps generally include a light source, a lamp holder and a lamp holder fixing plate. The lamp holder is fixed on the lamp body after being connected by the lamp holder fixing plate and screws. The light source is poorly connected, and the light source is damaged
When the electric spark generated by the light source due to poor contact emerges, it is easy to cause an explosion
In addition, when the light source is frequently replaced due to vibration damage, it is also easy to cause the explosion-proof components of the explosion-proof lamp to fail
[0003] Although some traditional explosion-proof lamps achieve vibration reduction through other structures such as springs, their structures are complex and their reliability is not high

Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an explosion-proof lamp and a lamp holder structure thereof. The lamp holder structure comprises a lamp holder fixing seat, a vibration-damping rubber sleeve, a lamp holder, a threaded fastening component and a threaded locking component, wherein the lamp holder fixing seat is provided with an accommodating opening; the vibration-damping rubber sleeve is of a sleeve body structure of which one end is opened and the other end is closed; the vibration-damping rubber sleeve is arranged in the lamp holder fixing seat through the accommodating opening; the closed end of the vibration-damping rubber sleeve is abutted against the cavity bottom of the lamp holder fixing seat; a lamp holder opening is formed in one end of the lamp holder; the other end of the lamp holder is arranged in the vibration-damping rubber sleeve; the outer diameter of the vibration-damping rubber sleeve is equal to the inner diameter of the lamp holder fixing seat, and the inner diameter of the vibration-damping rubber sleeve is equal to the outer diameter of the lamp holder, so that the vibration-damping rubber sleeve is tightly clamped between the lamp holder fixing seat and the lamp holder; the threaded fastening component penetrates through the lamp holder, the closed end of the vibration-damping rubber sleeve and the bottom of the lamp holder fixing seat; the threaded locking component is screwed with the threaded fastening component, so that the lamp holder, the vibration-damping rubber sleeve and the lamp holder fixing seat are detachably connected. The lamp holder structure is good in vibration-damping effect, is relatively simple in structure and is relatively high in reliability.

Description

technical field [0001] The invention relates to an illumination lamp, in particular to an explosion-proof lamp and its lamp holder structure. Background technique [0002] Explosion-proof lamps generally include a light source, a lamp holder and a lamp holder fixing plate. The lamp holder is fixed on the lamp body after being connected by the lamp holder fixing plate and screws. The light source is poorly connected and the light source is damaged. When the electric spark generated by the light source due to poor contact emerges, it is easy to cause an explosion. In addition, when the light source is frequently replaced due to vibration damage, it is also easy to cause the explosion-proof components of the explosion-proof lamp to fail. [0003] Although some traditional explosion-proof lamps achieve vibration reduction through other structures such as springs, their structures are complex and their reliability is not high.
