Description

Technical Field

[0001] The utility model relates to the technical field of chemical lighting lamps, in particular to a chemical explosion-proof lighting device. Background Technique

[0002] Inevitably, electric sparks or hot surfaces will be generated when lighting lamps are working. Therefore, explosion-proof lighting lamps are required in chemical environments. An explosion-proof lamp is a special lighting lamp that can prevent electric arcs, sparks and high temperatures that may be generated inside the lamp from igniting combustible gases and dust in the surrounding environment, so as to meet the explosion-proof requirements.

[0003] In the prior art, a wire frame is also provided outside the explosion-proof lamp. If the bulb breaks, the wire frame can effectively prevent the fragments from flying and can better resist external physical impacts and damages, thereby improving the durability and service life of the lamp.

[0004] However, the applicant found that when the external impact force is too large, the wire frame will be deformed and squeeze the explosion-proof lamp cover. For this reason, we propose a chemical explosion-proof lighting device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a chemical explosion-proof lighting device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A chemical explosion-proof lighting device includes a lamp housing and an explosion-proof net. A lamp body and an explosion-proof lamp cover are arranged at the bottom of the lamp housing, and the lamp body is located inside the explosion-proof lamp cover;

[0007] The explosion-proof net is located outside the explosion-proof lamp cover, and the top of the explosion-proof net is connected to a connecting ring;

[0008] A first spring is uniformly arranged horizontally on the outer side of the connecting ring. The first spring is arranged in an installation box, and a second spring connected to the installation box is uniformly arranged circumferentially at the bottom of the connecting ring;

[0009] Screws connected to the lamp housing are uniformly arranged at the top of the outer wall of the installation box.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By horizontally arranging a first spring on the side of the connecting ring and vertically arranging a second spring at the bottom, when the explosion-proof net is subjected to an external physical impact, the explosion-proof net drives the connecting ring to stretch the first spring and the second spring, which can buffer the impact force and prevent a large impact force from directly acting on the explosion-proof net, causing the explosion-proof net to deform and squeeze the explosion-proof lamp cover.

[0016] 2. By uniformly arranging third springs vertically on the top of the connecting ring, the third springs can not only support the explosion-proof net but also improve the buffering ability.

[0017] 3. By providing a buffer ring located inside the explosion-proof net on the inner wall of the connecting ring, when the explosion-proof net moves and buffers under impact, the buffer ring can first contact the explosion-proof lamp cover, preventing the explosion-proof net from directly contacting the explosion-proof lamp cover after moving and buffering, thus avoiding damage to the explosion-proof lamp cover.

[0023] Embodiment 1

[0024] Referring to Figures 1 to 2 , a chemical explosion-proof lighting device includes a lamp housing 1 and an explosion-proof net 4. A lamp body 2 and an explosion-proof lamp cover 3 are arranged at the bottom of the lamp housing 1, and the lamp body 2 is located inside the explosion-proof lamp cover 3;

[0025] The explosion-proof net 4 is located outside the explosion-proof lamp cover 3, and the top of the explosion-proof net 4 is connected to a connecting ring 7;

[0026] A first spring 8 is uniformly and horizontally arranged on the outer side of the connecting ring 7. The first spring 8 is arranged in an installation box 5. A second spring 9 connected to the installation box 5 is uniformly and circumferentially arranged at the bottom of the connecting ring 7;

[0027] The top of the outer wall of the installation box 5 is uniformly provided with screws 6 connected to the lamp housing 1 for fixing the installation box 5.

[0028] By arranging the first spring 8 horizontally on the side of the connecting ring 7 and the second spring 9 vertically at the bottom, when the explosion-proof net 4 is subjected to an external physical impact, hard collision can be avoided. The explosion-proof net 4 drives the connecting ring 7 to stretch the first spring 8 and the second spring 9, which can buffer the impact force, prevent a large impact force from directly acting on the explosion-proof net 4, making the explosion-proof net 4 not easily deformed, and thus avoiding the explosion-proof net 4 from deforming and squeezing the explosion-proof lamp cover 3, which affects the use of the lamp body 2.

[0029] A third spring 10 is uniformly and circumferentially arranged at the top of the connecting ring 7, and the tops of the third springs 10 are all connected to the inner wall of the installation box 5. The top third springs 10 can support the connecting ring 7 and can be stretched when subjected to forces in the vertical or horizontal directions, thereby improving the buffering ability of the explosion-proof net 4.

[0030] A first through groove 11 is arranged at the bottom of the installation box 5, and a second through groove 12 is arranged at the top of the installation box 5. The explosion-proof lamp cover 3 is located in the first through groove 11 and the second through groove 12 for the explosion-proof lamp cover 3 to pass through. The explosion-proof net 4 is located in the first through groove 11, so that the explosion-proof net 4 has space for movement and buffering.

[0032] Referring to Figure 2, a buffer ring 13 located outside the explosion-proof lamp cover 3 is provided on the inner wall of the connecting ring 7, and the buffer ring 13 is located inside the explosion-proof net 4. The buffer ring 13 is made of rubber, so that when the explosion-proof net 4 moves and is about to contact the explosion-proof lamp cover 3, the buffer ring 13 can contact the explosion-proof lamp cover 3 first, avoiding the situation that the explosion-proof net 4 directly contacts the explosion-proof lamp cover 3 after moving and buffering, resulting in damage to the explosion-proof lamp cover 3.

[0033] The rest of the structure is the same as that of Embodiment 1.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
