Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof lamps, and particularly relates to a safe explosion-proof lamp for industrial and mining use. Background Art

[0002] In the industrial and mining operation environment, due to the dark operation environment, lamps are needed to provide lighting for the workers' operation environment so that miners can work.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number CN202220940058.4 discloses a safe explosion-proof lamp for industrial and mining use, which includes a lamp housing and a lighting lamp arranged at the front end of the lamp housing. An explosion-proof lamp cover for covering the lighting lamp is arranged at the front end of the lamp housing. Four accommodating grooves are evenly arranged around the outer extension of the front section of the lamp housing, and a buffer spring is arranged in each accommodating groove; the explosion-proof lamp cover includes a lamp cover body and an installation ring. A number of special-shaped holes corresponding to the accommodating grooves on the lamp housing are formed in the installation ring. Four extending columns respectively passing through the corresponding special-shaped holes and extending to the rear end of the installation ring are evenly arranged at the rear end of the lamp cover body. A rotating sphere with the front end surface fitting the inner wall of the spherical hole is arranged at the end of each extending column. A limiting rod is arranged at the bottom of the rotating sphere, and a limiting ring is arranged on the rod body of the limiting rod. The installation ring is arranged at the front end of the lamp housing. The explosion-proof lamp cover of this utility model can buffer when being collided, and then can effectively protect the lighting lamp and the explosion-proof lamp cover, but there are still the following defects:

[0004] (1) The installation position of the explosion-proof lamp in the prior art is constant, and it is inconvenient to flexibly adjust the lighting angle according to the underground environment. At the same time, the earthquake resistance performance of the explosion-proof lamp in the prior art is poor. Vibration underground is likely to cause the lamp to resonate, easily leading to damage to the internal parts of the lamp and reducing the service life;

[0005] In the prior art, only the vertical protection of the lamp can be carried out through the explosion-proof lamp cover and the buffer spring. When the explosion-proof lamp cover is laterally impacted, the impact force is likely to be transmitted to the lamp, resulting in damage to the lamp, and the protection performance is poor.

[0033] As shown in Figure 1 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the adjusting structure 6 includes a driven gear 601 fixed on the rotating shaft 5. An engaging shaft 602 is provided on the upper side of the rotating shaft 5. Both ends of the engaging shaft 602 are rotatably connected to two support plates 4 respectively. A driving gear 603 meshing with the driven gear 601 is fixedly connected to the engaging shaft 602. A worm gear 604 is fixedly connected to the center of the engaging shaft 602. Two connecting pieces 605 are symmetrically and fixedly connected between the two support plates 4. A worm 606 meshing with the worm gear 604 is rotatably connected between the two connecting pieces 605. One end of the worm 606 is fixedly connected with a knob 607. By rotating the knob 607 to drive the worm 606 to rotate, the worm gear 604 and the engaging shaft 602 are driven to rotate.

[0037] Specifically, when this industrial and mining safety explosion-proof lamp is in operation / use: First, the fixing ears 11 and the mounting plate 1 are installed at the target position through the mounting components. When it is necessary to adjust the lighting angle, the worm 606 is driven to rotate by rotating the knob 607, and then the worm gear 604 and the connecting shaft 602 are driven to rotate. The driving gear 603 on the connecting shaft 602 meshes with the driven gear 601 on the rotating shaft 5, so as to realize the rotation of the rotating shaft 5. The rotation of the rotating shaft 5 drives the connecting frame 7, the lampshade 8 and the illuminating lamp 9 to rotate, thereby adjusting the irradiation angle of the lamp; when the lamp is vibrated, the first spring 304 and the damping rod 303 work together to absorb and relieve the vibration, protecting the internal components of the lamp from damage. When the explosion-proof cover 1004 receives a vertical impact force, the second spring 1002 can buffer the explosion-proof cover 1004. When receiving a lateral impact force, the third spring 1006 buffers the connecting ring 1003, thereby buffering the explosion-proof cover 1004, and then being able to provide good protection for the illuminating lamp 9.
