[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a built-in explosion-proof lighting fixture for use in a test chamber, comprising:

[0026] Explosion-proof lighting fixtures 11;

[0027] Explosion-proof lighting fixture 11 provides the necessary lighting inside the test chamber.

[0028] The convenient installation mechanism includes a mounting bracket 21 that is threadedly fixed to the top of the test chamber and a positioning bracket 22 that is slidably connected to the middle of the lower end of the mounting bracket 21. The middle of the lower end of the positioning bracket 22 is threadedly fixed to the upper end of the explosion-proof lamp 11. One end of the mounting bracket 21 is fixed with a positioning hole block 25, and one side end of the positioning bracket 22 is fixed with a protruding post 26. The protruding post 26 and the opening on the positioning hole block 25 are fitted together. The other side of the positioning bracket 22 is provided with a movable handle 27.

[0029] Mounting bracket 21 supports the positioning bracket 22 for installation. The positioning bracket 22 is used to install and fix the explosion-proof lamp 11. By sliding the positioning bracket 22 within the mounting bracket 21, the explosion-proof lamp 11 can be easily moved to the outside of the test chamber by applying force from the outside. This allows for close-range external inspection and maintenance of the explosion-proof lamp 11, saving time and effort. The engagement between the protruding post 26 and the opening on the positioning hole block 25 can structurally fix the explosion-proof lamp 11 when it is moved into the test chamber. The movable handle 27 applies force to disassemble and assemble the explosion-proof lamp 11.

[0030] One end of the movable handle 27 is fixed with a threaded post 29, and the middle of the other side of the positioning frame 22 is provided with a threaded tube 28, with the threaded post 29 extending into the threaded tube 28.

[0031] The threaded connection between the threaded tube 28 and the threaded post 29 connects the movable handle 27 and the positioning bracket 22 for installation.

[0032] The other end of the handle 27 is fitted with an anti-slip sleeve 210;

[0033] The anti-slip sleeve 210 increases contact friction, which helps to control the structure of the movable handle 27.

[0034] The mounting bracket 21 has guide grooves in the middle of its front and rear ends, and the positioning bracket 22 has guide blocks fixed on the upper part of its front and rear ends. The guide blocks and guide grooves are slidably connected to each other and extend outward.

[0035] The sliding of the guide block in the guide groove guides the position of the positioning frame 22, which slides in the same way.

[0036] Working principle: When the explosion-proof lamp 11 is installed at the top inside the test chamber, the movable handle 27 is installed on the positioning frame 22 by means of the threaded connection between the threaded tube 28 and the threaded post 29. The movable handle 27 is then gripped by the anti-slip sleeve 210, and an inward pushing force is applied to the positioning frame 22. By sliding the positioning frame 22 in the mounting frame 21 and by guiding the sliding of the limiting block 24 in the limiting groove 23, the positioning frame 22 is gradually moved into the test chamber. Then, the positioning frame 22 is structurally fixed by the interlocking of the protruding post 26 and the positioning hole block 25, thus installing the explosion-proof lamp 11 inside the test chamber. For subsequent disassembly, inspection and maintenance, the reverse steps are applied.

[0037] This solution allows for the disassembly, assembly, and maintenance of the explosion-proof lighting fixture 11 without entering the test chamber, saving time and effort, and is simple, convenient, and improving the effectiveness of use.

[0038] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0039] It also includes an auxiliary wiring mechanism, which includes a first movable frame 32, a second movable frame 33, a third movable frame 34 and a fourth movable frame 35 arranged sequentially through the middle of the top of the test chamber. The first movable frame 32, the second movable frame 33 and the third movable frame 34 are symmetrically provided with movable springs in the middle cavity, and are respectively fixed to one end of the second movable frame 33, the third movable frame 34 and the fourth movable frame 35. The other end of the fourth movable frame 35 is provided with a docking hole 37, which is opposite to the wiring hole of the explosion-proof lamp 11.

[0040] The auxiliary wiring mechanism also includes a sealing strip 36, which symmetrically fills the connection gaps between the second movable frame 33, the third movable frame 34 and the fourth movable frame 35 and the top of the test chamber;

[0041] The movable springs connect the first movable frame 32, the second movable frame 33, the third movable frame 34, and the fourth movable frame 35 in sequence. The cavity allows for the movement and extension of the first movable frame 32, the second movable frame 33, the third movable frame 34, and the fourth movable frame 35. With the use of the sealing strip 36, the top of the test chamber can be sealed and the movement of the explosion-proof lamp 11 can be accommodated. The mating hole 37 is used for the wiring of the explosion-proof lamp 11.

[0042] The auxiliary wiring mechanism also includes a fixing block 31 fixedly connected to one side of the middle of the top of the test chamber, and one end of the fixing block 31 is fixed to the first movable frame 32.

[0043] The fixing block 31 is used to install and fix the first movable frame 32.

[0044] Working principle: During the maintenance and repair of the explosion-proof lamp 11, as the positioning frame 22 moves outward, the force acts on the fourth movable frame 35 and is transmitted sequentially to the third movable frame 34 and the second movable frame 33. At this time, the movable spring, after being compressed by the force, moves the fourth movable frame 35 inward toward the third movable frame 34, the third movable frame 34 toward the second movable frame 33, and the second movable frame 33 toward the first movable frame 32. This allows the positioning frame 22 to move smoothly to the outer side of the test chamber. When the force is released, the second movable frame 33, the third movable frame 34, and the fourth movable frame 35 return to their original positions, and then the sealing strip 36 is used to re-seal the area.

[0045] This solution, while allowing for the relocation, disassembly, and wiring of the explosion-proof lighting fixture 11, ensures the airtightness of the test chamber structure, facilitates use, and meets the requirements.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
