Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof lamps, and in particular to a quick-install lampshade structure for explosion-proof lamps. Background Art

[0002] Explosion-proof lamps are used in dangerous places where flammable gases and dust exist. They can prevent the arc, sparks and high temperature that may be generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thereby meeting the explosion-proof requirements. In order to improve the focusing ability of the lamp, a lampshade will be added to the lamp.

[0003] After searching, the Chinese patent publication number CN203442748U discloses "an explosion-proof lighting fixture, including a lampshade, a transparent cover, an electrical chamber and a tail cover, wherein the upper opening of the lampshade is provided with a transparent cover, and a basin-shaped reflector is provided inside the transparent cover, the lampshade, the electrical chamber and the tail cover are fixedly connected with explosion-proof bolts in sequence, the light source is placed in the lampshade, a partition is provided between the lampshade and the electrical chamber, a cable introduction hole is provided at the upper end of the tail cover, a sealing rubber plug is provided in the cable introduction hole, a bracket is provided on the lampshade, and a bracket locking device is provided at the connection between the bracket and the lampshade";

[0004] The above patent places the "light source" in the "lampshade", that is, the "lampshade" is connected to the "electrical room" and the "tail cover" to form an integral structure, and the "lampshade" is non-detachable; among them, when explosion-proof lamps are actually used, not all scenes require a "lampshade" for focusing light. When a lampshade is not needed in certain specific usage scenarios, you can only purchase an explosion-proof lamp without a lampshade, which causes unnecessary waste. Utility Model Content

[0029] During installation, the installation sleeve 21 is sleeved on the outer side of the lamp holder 12, and the slot 24 is matched with the corresponding block 14, and then the block 14 is limited to separate from the slot 24 by the limit member 25, so that the installation sleeve 21 is fixed to the outer side of the lamp holder 12, and the installation of the reflector 22 is realized; during disassembly, the restriction on the block 14 is released by the limit member 25, that is, the installation sleeve 21 and the reflector 22 can be directly removed, which realizes the quick disassembly and assembly of the reflector 22, so that the reflector 22 can be installed or removed according to the actual usage scenario, thereby increasing the scope of use of the lamp assembly 1.

[0030] Reference Figure 3-Figure 4 A plurality of guide blocks 23 are fixedly connected to the inner wall of the installation sleeve 21, and the guide blocks 23 are distributed at equal angles around the installation sleeve 21. A plurality of guide grooves 15 matching the guide blocks 23 are provided on the outer wall of the lamp holder 12, and the guide blocks 23 are slidably matched with the corresponding guide grooves 15. The guide blocks 23 cooperate with the guide grooves 15 to guide the installation sleeve 21, so that the clamping block 14 can accurately cooperate with the corresponding clamping groove 24, so that the installation sleeve 21 and the reflector 22 can be quickly installed.

[0031] Reference Figure 5The block 14 is an L-shaped structure, and the bottom area of ​​the horizontal section is equal to the opening area of ​​the corresponding slot 24. The limiting member 25 includes a slide bar 251, which is slidably connected to the bottom end of the side wall of the corresponding slot 24. The slide bar 251 penetrates the side wall of the corresponding slot 24 and extends to the outside of the mounting sleeve 21. One end of the slide bar 251 is fixedly connected with a wedge-shaped limiting block 252, which is located on the inner side of the slot 24.

[0032] Reference Figure 6 A protective component 3 is provided on the outer side of the lamp body 13, and the protective component 3 includes a ring 31, which is sleeved on the top of the lamp body 13, and the top wall of the ring 31 is fixedly connected with a plurality of docking blocks 33, and the plurality of docking blocks 33 are evenly distributed around the ring 31, and the tops of the plurality of docking blocks 33 are slidably connected with the bottom wall of the lamp holder 12, and a metal mesh cover 32 is fixedly connected to the bottom of the ring 31, and the metal mesh cover 32 is sleeved on the outer side of the lamp body 13, and the length of the metal mesh cover 32 is greater than the length of the lamp body 13.

[0033] Reference Figure 7 The outer edge of the bottom wall of the lamp holder 12 is provided with a plurality of docking grooves 16 corresponding to the docking blocks 33, and a plurality of docking blocks 33 are slidably matched with the corresponding docking grooves 16. Both the docking blocks 33 and the docking grooves 16 are L-shaped structures, and the area of ​​the horizontal section of the docking block 33 is equal to the opening area of ​​the vertical section of the docking groove 16.

[0034] The working principle of the utility model is as follows: when installing the reflector 22, the installation sleeve 21 is sleeved on the outer side of the lamp holder 12, and the card slot 24 is matched with the corresponding card block 14, so that the horizontal section of the card block 14 contacts the corresponding wedge-shaped limit block 252 and applies a force to it. After the wedge-shaped limit block 252 is acted upon, it will move into the storage groove 254, and at this time, the return spring 255 is squeezed and accumulates elastic potential energy. When the card block 14 is fully matched with the card slot 24, the wedge-shaped limit block 252 is no longer subjected to the force of the card block 14, and the return spring 255 is pressed into the storage groove 254. 255 releases the potential energy, which makes the wedge-shaped limit block 252 return to the initial position and restrict the horizontal section of the clamping block 14, so that the clamping block 14 can be restricted from being separated from the clamping slot 24, thereby realizing the installation of the mounting sleeve 21 and the reflector 22; when removing the reflector 22, all the pull blocks 253 are pulled outward to make all the slide bars 251 slide outward, so that all the wedge-shaped limit blocks 252 are separated from the corresponding clamping blocks 14, so that the mounting sleeve 21 and the reflector 22 can be directly removed, thereby realizing the rapid disassembly and assembly of the reflector 22;

[0035] When installing the metal mesh cover 3, the ring 31 is sleeved on the outside of the lamp body 13, and the docking block 33 on the top of the ring 31 is matched with the corresponding docking groove 16. Then the ring 31 is rotated to make the horizontal section of the docking block 33 slide into the horizontal section of the docking groove 16. At this time, the horizontal section of the docking block 33 is staggered with the vertical opening of the docking groove 16, which can prevent the docking block 33 from detaching from the docking groove 16, thereby realizing the installation of the metal mesh cover 3. The whole process is simple to operate, which greatly reduces the difficulty of installing the metal mesh cover 3.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
