[0027] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0028] Please see Figures 1-9This utility model provides a tri-proof lamp with an easily detachable end cap, including a shell 1, a plug 2, a connecting sleeve 3, an end cap 4, and a light-emitting module 5. The plug 2 and the connecting sleeve 3 are respectively fixedly installed at opposite ends of the shell 1. The two ends of the connecting sleeve 3 are open. The light-emitting module 5 passes through the connecting sleeve 3 and is inserted into the shell 1. The end cap 4 is detachably fitted onto the outside of the connecting sleeve 3. A sliding groove 310 is provided on the outer wall of the connecting sleeve 3. The sliding groove 310 includes a guide groove 311 opened along the axial direction and a locking groove 312 opened along the circumferential direction. The guide groove 311 and the locking groove 312 are interconnected. A locking block 410 is provided on the end cap 4. The locking block 410 can slide along the sliding groove 310 and be locked into the sliding groove 310. A limiting plate 420 is provided inside the end cap 4. One end of the light-emitting module 5 abuts against the plug 2, and the other end of the light-emitting module 5 abuts against the limiting plate 420.
[0029] This utility model of an easily detachable end cap tri-proof lamp is installed by first fixing the plug 2 and the connecting sleeve 3 to the opposite ends of the outer shell 1. Then, the light-emitting module 5 is inserted into the outer shell 1 through the end where the connecting sleeve 3 is located, so that one end of the light-emitting module 5 abuts against the plug 2. Next, the end cap 4 is placed on one side of the connecting sleeve 3, and the locking block 410 is aligned with the guide groove 311. Then, the end cap 4 is moved in the direction close to the connecting sleeve 3, so that the locking block 410 is inserted into the guide groove 311. When the locking block 410 slides to the end of the guide groove 311, the end cap 4 is rotated, and the locking block 410 slides along the slot 312 and finally locks into the end of the slot 312. At the same time, the limiting plate 420 abuts against the other end of the light-emitting module 5. While fixing the end cap 4 and the connecting sleeve 3 to each other, the light-emitting module 5 is also fixed inside the outer shell 1.
[0030] When the light-emitting module 5 malfunctions and needs to be repaired or replaced, the user only needs to rotate the end cover 4 in the opposite direction to drive the locking block 410 to slide along the locking groove 312 to one end of the guide groove 311. Then, move the end cover 4 away from the connecting sleeve 3 to disengage the locking block 410 from the sliding groove 310. At this time, the end cover 4 is removed from the connecting sleeve 3, and the restraining effect of the limiting plate 420 on the light-emitting module 5 is released. Then, the light-emitting module 5 can be pulled out from the outer shell 1 through the opening of the connecting sleeve 3, and then the light-emitting module 5 can be repaired or replaced.
[0031] Compared to existing technologies that use interference fits or bolts for connection, the tri-proof lamp of this invention can be disassembled and assembled with the end cover 4 and the light-emitting module 5 with simple rotation and plugging actions. The end cover 4 is easy to open, which is conducive to maintenance and replacement operations, improves disassembly and assembly efficiency, and greatly enhances the user experience.
[0032] Please see Figure 7 , Figure 8In this embodiment, the connecting sleeve 3 includes a fixing ring 31 and a connecting cylinder 32. The fixing ring 31 matches the outer shape of the outer shell 1 and is interference-fitted with the outer shell 1. The connecting cylinder 32 is fixedly connected to the end face of the fixing ring 31. The fixing ring 31 is an annular structure with both ends through it. A groove 310 is formed on the outer side wall of the fixing ring 31. The groove 310 does not penetrate the inner side wall of the fixing ring 31, which to a certain extent ensures the structural strength of the fixing ring 31. The end cap 4 includes a cap body 41 and a connecting plate 42. The cap body 41 is fixedly connected to the outer shell 1. The cap body 41 has a shell structure with one end open. The outer shape of the cap body 41 matches the fixing ring 31. When the end cap 41 and the connecting sleeve 3 are connected in place, the cap body 41 and the fixing ring 31 are aligned, thereby ensuring the consistency of the overall appearance of the tri-proof lamp and improving its aesthetics. The connecting plate 42 is fixedly connected inside the cover body 41. The inner wall of the connecting plate 42 has an arc-shaped structure. The locking block 410 is fixedly installed on the inner wall of the connecting plate 42. The inner wall of the connecting plate 42 cooperates with the outer wall of the connecting cylinder 32. In this way, when the end cover 4 moves relative to the connecting sleeve 3, the inner wall of the connecting plate 42 and the outer wall of the connecting cylinder 32 are always in contact with each other, and the two have a mutual limiting effect, thereby improving the stability of the end cover 4 and effectively preventing the end cover 4 from moving relative to the connecting sleeve 3.
[0033] In a preferred embodiment, the connecting plate 42 is fixedly connected to the inner bottom wall of the cover body 41. The connecting plate 42 has an arc-shaped plate structure, and both ends of the connecting plate 42 protrude outward to form extensions 421. The extensions 421 are fixedly connected to the inner side wall of the cover body 41. This enhances the connection strength between the connecting plate 42 and the cover body 41, effectively preventing the connecting plate 42 from easily deforming, thereby ensuring the alignment relationship between the locking block 410 and the sliding groove 310 on the connecting plate 42.
[0034] In this embodiment, there are four connecting plates 42, which are evenly distributed on the outside of the connecting cylinder 32 to ensure balanced force distribution and further improve the connection reliability between the end cap 41 and the connecting sleeve 3. In other embodiments not shown, the connecting plate 42 can also be a complete annular structure, with multiple locking blocks 410 evenly distributed on the inner wall of the connecting plate 42.
[0035] Please see Figure 2 , Figure 9The easy-to-remove end cap tri-proof lamp of this utility model also includes a sealing element 6, which is installed between the connecting sleeve 3 and the end cap 4 to achieve a seal. Specifically, the sealing element 6 is installed on the inner bottom wall of the cover body 41, and the side of the connecting cylinder 32 away from the fixing ring 31 abuts against the sealing element 6. As a preferred embodiment, a limiting baffle 411 is fixedly connected to the inner bottom wall of the cover body 41. The limiting baffle 411 is located inside the connecting plate 42, and the sealing element 6 is installed in the space enclosed by the limiting baffle 411 and the connecting plate 42. In addition, a limiting groove 412 is opened on the side wall of the limiting baffle 411, and a limiting protrusion 61 that cooperates with the limiting groove 412 is provided on the inner wall of the sealing element 6. During installation, the limiting groove 412 and the limiting protrusion 61 cooperate with each other, restricting the rotation of the sealing element 6 and improving the installation stability of the sealing element 6. Additionally, the locking block 410 is located on the side of the seal 6 near the connecting sleeve 3. The locking block 410 also acts as a barrier for the seal 6, effectively preventing the seal 6 from detaching from the space enclosed by the limiting baffle 411 and the connecting plate 42. The seal 6 is made of silicone or rubber.
[0036] After the end cap 41 and the connecting sleeve 3 are installed in place, the sealing element 6 is pressed against the inner bottom wall of the cap body 41 by the connecting cylinder 32. The sealing element 6 can deform under pressure, and the elastic force generated after deformation acts on the connecting cylinder 32, so that the connecting cylinder 32 has a tendency to move away from the cap body 41. In this way, the locking block 410 and the groove side wall of the locking groove 312 are more tightly connected, which can prevent the locking block 410 and the locking groove 312 from easily separating.
[0037] As a preferred embodiment, the side of the groove wall of the card slot 312 away from the fixing ring 31, near the guide groove 311, is provided with a slope 313. The slope 313 can guide the card block 410 into the card slot 312, which is conducive to the user quickly and smoothly inserting the card block 410 into the card slot 312.
[0038] The outer casing 1 has a tubular structure that extends through both ends. Slots 11 are provided on opposite sides of the inner wall of the outer casing 1. The opposite sides of the light-emitting module 5 can be slidably inserted into the slots 11 to restrict the position of the light-emitting module 5. In addition, the outer casing 1 is made of aluminum alloy, which not only achieves lightweight production but also provides good heat dissipation.
[0039] Please see Figure 6 In this embodiment, the light-emitting module 5 includes a fixing plate 51, a circuit board 52, and a light strip 53. The fixing plate 51 has a flat plate structure. Both sides of the fixing plate 52 are respectively inserted into the slots 11. The circuit board 52 is fixedly installed on the fixing plate 51. The light strip 53 is installed on the circuit board 52 and is electrically connected to the circuit board 52. The light strip 53 includes, but is not limited to, LED lights.
[0040] Please see Figure 5 In this embodiment, a wire threading bolt 7 is installed at the center of the end of the end cap 4 away from the connecting sleeve 3. A through hole 71 is opened in the center of the wire threading bolt 7. The through hole 71 is used for the wires connected to the circuit board 52 to pass through. A locking nut 72 is installed on the end of the wire threading bolt 7 located inside the end cap 4. A support surface 73 is provided on the outer wall of the wire threading nut 7. The bottom wall of the end cap 4 is sandwiched between the support surface 73 and the locking nut 72.
[0041] The connection between the plug 2 and the connecting sleeve 3 and the outer shell 1 can be an interference fit, a snap-fit connection or a bolt connection, and there is no limitation here.
[0042] This utility model of an easy-to-remove end cap tri-proof light allows for easy disassembly and assembly of the end cap 4 and fixation of the light-emitting module 5 through simple rotation and insertion. The end cap 4 is easy to open, which is beneficial for maintenance and replacement operations, improves disassembly and assembly efficiency, and greatly enhances the user experience.
[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model.
