Description

Technical Field

[0001] This utility model relates to the field of explosion-proof lighting technology, specifically to a quick-installation explosion-proof lighting fixture. Background Technology

[0002] Explosion-proof lamps are lighting fixtures used in hazardous locations where flammable gases and dust may be present. They are designed to prevent potential arcs, sparks, and high temperatures generated inside the lamp from igniting the surrounding flammable gases and dust, thus meeting explosion-proof requirements. They are also known as explosion-proof lighting fixtures or explosion-proof lamps. Different flammable gas mixtures require different explosion-proof ratings and types of explosion-proof lamps.

[0003] Chinese Patent Publication No. CN222278358U discloses a quick-installation explosion-proof lighting fixture, including a mounting base. A connecting block is fixedly provided on the lower end face of the mounting base at the middle position. The lower end face of the connecting block has an installation hole, and the mounting block is provided inside the installation hole. A lamp holder is fixedly provided on the lower end face of the mounting block, and an explosion-proof lamp body is movably provided at the lower end of the lamp holder. Pins are slidably provided on both sides of the outer wall of the connecting block, and corresponding insertion holes are provided on the outer wall of the mounting block. One end of each pin is located inside the insertion hole, and the other end of each pin is fixedly provided with a pull block. A first spring is fixedly provided between the pull block and the connecting block, so that the mounting block can be inserted into the installation hole and pressed, allowing the pin to enter the insertion hole through the action of the first spring for easy installation. For disassembly, simply pull the pull block outward to disengage the pin from the insertion hole, facilitating maintenance of the explosion-proof lighting fixture body.

[0004] However, the existing light bulbs mentioned above require constant twisting and rotating many times during installation to completely fix the bulb in the mounting bracket, which takes a certain amount of time. Therefore, there is an urgent need for a quick-installation explosion-proof light fixture. Utility Model Content

[0005] The purpose of this invention is to provide a quick-installation explosion-proof lighting fixture to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-installation explosion-proof lamp, including a mounting plate, a lamp holder installed at the bottom of the mounting plate, and an explosion-proof lamp body provided at the bottom of the lamp holder;

[0007] A docking ring is fixedly connected to the outer side of the lamp holder. A ring groove is opened inside the docking ring. Multiple first springs are fixedly connected to the inner top wall of the ring groove. The bottom of the multiple first springs is fixedly connected to the same pressure ring. Multiple first slots are opened at the bottom of the docking ring. Multiple first L-shaped brackets are opened at the top of the explosion-proof lamp body.

[0008] Preferably, the plurality of the first L-shaped brackets are arranged in a circular array, and the plurality of the first slots are adapted to the first L-shaped brackets.

[0009] During installation, use an electric drill or screwdriver to drill holes at the installation location and install expansion plugs or anchors. Fix the mounting plate to the expansion plugs or anchors with screws. Align the top of the explosion-proof lamp body with the mating ring of the lamp holder to ensure that the first L-shaped bracket can be smoothly inserted into the first slot. Gently press the explosion-proof lamp body to fully insert the first L-shaped bracket into the first slot and squeeze the first spring to compress it, so that the first L-shaped bracket is inserted into the ring groove.

[0010] Preferably, the plurality of first springs are arranged in a ring array, and the pressure ring is slidably disposed within the ring groove.

[0011] Preferably, the outer side of the mounting plate is fixedly connected with multiple mounting ears, and the multiple mounting ears are arranged in a ring array.

[0012] Rotate the explosion-proof lamp body to move the first L-shaped bracket from the first slot into the annular groove, then release the explosion-proof lamp body, and under the action of the first spring, press the multiple first L-shaped brackets together, thus completing the installation of the explosion-proof lamp body and the lamp holder.

[0013] Preferably, a protective cover is fixedly connected to the bottom of the mounting plate, a transparent cover is provided at the bottom of the protective cover, a mounting ring is fixedly connected to the top of the transparent cover, and a plurality of second L-shaped brackets are fixedly connected to the outer side of the mounting ring, with a limit groove provided on one side of each second L-shaped bracket.

[0014] Preferably, a plurality of insert blocks are fixedly connected to the outer side of the protective cover, and each of the plurality of insert blocks has a movable groove on its outer side. A limit block is slidably arranged inside each movable groove. A second spring is fixedly connected to one end of each limit block, and the end of each second spring away from the limit block is fixedly connected to the inner wall of the movable groove.

[0015] Align the mounting ring of the transparent cover with the insert of the protective cover to ensure that the second L-shaped insert can be smoothly inserted into the second slot of the insert. Gently press the transparent cover to fully insert the second L-shaped insert into the second slot. Under the action of the second spring, the limiting block slides in the movable groove and springs into the limiting groove of the second L-shaped insert, thereby achieving fixation.

[0016] Preferably, each of the insert blocks has a second slot on its front side that communicates with the movable slot, each of the second slots is adapted to the second L-shaped insert, and each of the limiting blocks is adapted to the limiting slot.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] Firstly, in this utility model, multiple mounting ears on the outer side of the mounting plate are used to install the lamp holder in the required position. During installation, holes are drilled at the installation position using an electric drill or screwdriver, and expansion plugs or anchors are installed. The mounting plate is then fixed to the expansion plugs or anchors with screws. The top of the explosion-proof lamp body is aligned with the mating ring of the lamp holder, ensuring that the first L-shaped bracket can be smoothly inserted into the first slot. The explosion-proof lamp body is gently pressed to fully insert the first L-shaped bracket into the first slot, and the first spring is squeezed to contract, causing the first L-shaped bracket to insert into the annular groove. Then, the explosion-proof lamp body is rotated to allow the first L-shaped bracket to move from the first slot into the annular groove. The explosion-proof lamp body is then released, and the multiple first L-shaped brackets are pressed together under the action of the first spring. At this point, the installation of the explosion-proof lamp body and the lamp holder is completed. When it is necessary to remove the explosion-proof lamp body, the explosion-proof lamp body is pressed to contract the first spring, and the explosion-proof lamp body is rotated to allow the first L-shaped bracket to rotate out of the first slot, thus greatly saving the efficiency of disassembling and assembling the explosion-proof lamp body.

[0019] Secondly, in this utility model, the mounting ring of the transparent cover is aligned with the insert block of the protective cover to ensure that the second L-shaped insert can be smoothly inserted into the second slot of the insert block. The transparent cover is gently pressed to make the second L-shaped insert fully inserted into the second slot. Under the action of the second spring, the limiting block slides in the movable groove and springs into the limiting groove of the second L-shaped insert, thereby achieving fixation. When it is necessary to remove the transparent cover, the limiting blocks are pressed to make the second spring contract, releasing the limiting of the second L-shaped insert, and it can be removed, achieving the effect of convenient removal of the transparent cover.
