Description

Technical Field

[0001] This utility model relates to a lighting fixture, and more particularly to a quick-install tri-proof lighting fixture, suitable for factory warehouses, underground parking garages, corridors and other places. Background Technology

[0002] A lighting fixture is an appliance that transmits, distributes, and alters the distribution of light sources. It includes all components necessary for fixing and protecting the light source, such as the lamp housing, lamp shade, lamp base plate, and the wiring accessories required for power connection, excluding the light source itself. Currently, lamp housings and shades, as well as lamp housings and lamp base plates, are fixed together using screws. This installation process is labor-intensive, time-consuming, and requires a large number of screws, resulting in high costs.

[0003] For example, Chinese utility model patent ZL201720337741.8 (publication number CN206817233U) discloses a tri-proof lamp, including a lamp body, a heat sink, a light source assembly, a lampshade, a driving power supply, and an emergency component. The lamp body is connected to the heat sink, forming a mounting cavity. The light source assembly is located outside the mounting cavity and is mounted on the heat sink. The lampshade is connected to the lamp body and encloses the light source assembly and the heat sink within it. Both ends of the lamp body and the lampshade are open structures, and both ends are sealed by end caps and end cap sealing rings. The end cap sealing rings are positioned between the end caps and the openings. After the lamp body and the lampshade are connected, the end cap sealing rings are placed at both ends of the lamp body, and the end caps press against the end cap sealing rings. The end caps are connected to the lamp body by screws.

[0004] The existing end caps are all fixed with screws, which require hand tools to disassemble and assemble, and there are multiple screws, making disassembly and assembly time-consuming. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a quick-installation tri-proof lamp that does not require screws and can be installed, in view of the above-mentioned technical status.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a quick-install tri-proof lamp, including a lamp body, and end cap assemblies are provided at the left and right ends of the lamp body; characterized in that: the end cap assembly includes a fixed cover, a terminal cover and a movable cover, the fixed cover has a first mounting end and a second mounting end, the first mounting end is sleeved and fixed to the end of the lamp body, the terminal cover is axially inserted and snapped into the fixed cover, and a wiring terminal is installed in the terminal cover, the second mounting end is annular, and an mounting groove is formed on the outer peripheral wall of the second mounting end, and a sealing ring is provided in the mounting groove, the movable cover is sleeved and fixed outside the second mounting end by a screw-on structure, and the sealing ring forms a seal with the inner wall of the movable cover.

[0007] To ensure precise insertion and locking of the terminal cover within the fixed cover, an improvement is made by incorporating a radially protruding guide block at the bottom of the fixed cover, and a locking hole on each of the front and rear sides of the fixed cover. The bottom inner side of the terminal cover has a guide groove that matches the guide block, and a resilient locking foot on each of the front and rear sides of the terminal cover. After the terminal cover is axially inserted into the fixed cover, the guide block aligns with the guide groove, and each of the resilient locking feet engages with its corresponding locking hole. The cooperation between the guide block and the guide groove guides the insertion of the terminal cover, ensuring it is inserted in the correct direction. During insertion, the resilient locking feet retract and deform until they are fully engaged, locking into their respective locking holes, thus completing the installation of the terminal cover within the fixed cover. This assembly is quick and precise, eliminating the need for screws.

[0008] To allow for quick cutting of the terminals without the need for screws, mounting holes are provided inside the terminal cover. The terminals are inserted from the inside out and snapped into the mounting holes.

[0009] Furthermore, the terminal cover has a pre-installed location for external color temperature and power adjustment DIP switches, which are concealed by a movable cover. This design allows for the customization of external color temperature and power adjustment DIP switches. When color temperature or power needs adjustment, simply open the movable cover for adjustment; there is no need to disassemble the entire terminal cover assembly. Moreover, the movable cover is very easy to install and remove, making overall operation more convenient.

[0010] As a specific structure for the detachable connection between the movable cover and the fixed cover, the aforementioned screw-lock structure includes multiple L-shaped locking ribs spaced circumferentially along the inner wall of the movable cover and multiple L-shaped locking grooves on the outer peripheral wall of the second mounting end. The locking ribs have axial ribs extending axially and transverse ribs located at the inner end of the axial ribs and arranged circumferentially. The locking grooves have axial grooves extending axially and transverse grooves arranged circumferentially. The inner ends of the transverse grooves and the axial grooves are interconnected. The width of the axial groove is greater than that of the transverse rib. When the movable cover is fitted onto the second mounting end and moves axially inward, the transverse ribs enter the bottom along the axial groove. When the movable cover is rotated, the transverse ribs enter the transverse groove and complete the fixation of the movable cover on the second mounting end.

[0011] To prevent the installed movable cover from easily loosening, one or more stop protrusions are provided on the outer peripheral wall of the second mounting end. These stop protrusions are located within the axial groove and close to the inner wall of the transverse groove, forming a limiting distance between them. When the movable cover is fixed to the second mounting end, the axial rib overcomes resistance and passes over the stop protrusions into the limiting distance. The engagement of the positioning protrusions and the axial ribs ensures that a certain amount of torque is required to rotate the movable cover during installation and removal.

[0012] In a further improvement, the inner end of the first mounting end is provided with an annular inner mounting groove for the end of the lamp body to be inserted. The end of the lamp body is inserted and fixed in the inner mounting groove with waterproof adhesive. The inner mounting groove provides a certain degree of constraint on the end of the lamp body. The adhesive bonding method has the advantage of reliable bonding, and the waterproof adhesive also provides waterproofing, ensuring a screwless design.

[0013] To ensure the accurate relative installation position of the fixing cover and the lamp body, the front and rear walls of the lamp body are provided with limiting grooves extending along the length direction, and the inner end of the first mounting end is provided with a limiting block embedded in the limiting groove.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: The end cover assembly comprises three main components: a fixed cover, a terminal cover, and a movable cover. The fixed cover has a first mounting end and a second mounting end. The first mounting end is sleeved and fixed to the end of the lamp body. The terminal cover is axially inserted and snapped into the fixed cover. The movable cover is sleeved and fixed to the outside of the second mounting end through a screw-on structure. The sealing ring forms a seal with the inner wall of the movable cover. The entire installation process does not require screws. In particular, the installation of the terminal cover inside the fixed cover and the installation of the movable cover on the fixed cover are both done using a snap-on method. The disassembly of the movable cover is more convenient than screw installation. The overall appearance is simple and elegant. After the movable cover is removed, the end of the lamp body is still covered by the fixed cover and the terminal cover, which protects the internal lamp body. The wiring terminals are exposed under the fixed cover. After the movable cover is removed, wiring operations can be performed. The lamp installation workload is small and time-saving, and it also saves the cost of consumables such as screws, making the lamp cost lower. Attached Figure Description

[0027] The terminal cover 3 has a mounting hole 33, and the wiring terminal 6 is inserted from the inside out and snapped into the mounting hole 33. The terminal cover 3 has a reserved position 34 for DIP switches, which is used to install an external color temperature DIP switch 7 and an external power adjustment DIP switch 8. The DIP switch position 34 is covered by a movable cover 5.

[0028] The locking structure includes multiple L-shaped locking ribs 9a spaced circumferentially along the inner wall of the movable cover 5, and multiple L-shaped locking grooves 9b on the outer circumferential wall of the second mounting end 2b. The locking ribs 9a have axial ribs 9a1 extending axially and transverse ribs 9a2 located at the inner end of the axial ribs 9a1 and arranged circumferentially. The locking grooves 9b have axial grooves 9b1 extending axially and transverse grooves 9b2 arranged circumferentially. The transverse grooves 9b2 are connected to the inner ends of the axial grooves 9b1. The width of the axial grooves 9b1 is greater than that of the transverse ribs 9a2. When the movable cover 5 is fitted onto the second mounting end 2b and moves axially inward, the transverse ribs 9a2 enter the bottom along the axial grooves 9b1. When the movable cover 5 is rotated, the transverse ribs 9a2 enter the transverse grooves 9b2, thus fixing the movable cover 5 on the second mounting end 2b.

[0029] One or more stop protrusions 9c are provided on the outer peripheral wall of the second mounting end 2b. The stop protrusions 9c are located in the axial groove 9b1 and close to the inner side wall of the transverse groove 9b2. A limiting distance is formed between the stop protrusions 9c and the inner side wall of the transverse groove 9b2. When the movable cover 5 is fixed on the second mounting end 2b, the axial rib 9a1 overcomes the resistance and passes through the stop protrusions 9c to enter the limiting distance.

[0030] The inner end of the first mounting end 2a is provided with an annular inner mounting groove 2a1 for the end of the lamp body 1 to be inserted. The end of the lamp body 1 is inserted and fixed in the inner mounting groove 2a1 with waterproof glue. The front and rear walls of the lamp body 1 are provided with limiting grooves 11 extending along the length direction.
