[0002] This application claims priority to Chinese Patent Application No. 202421163187.2, filed on May 27, 2024, entitled "Snap-on Structure and Lighting Fixture", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to a snap-fit ​​structure and a lamp, belonging to the field of lighting technology. Background Technology

[0004] Linear lighting fixtures are among the most common types of lighting fixtures on the market. They are installed by snapping together the lamp housing and the diffuser plate.

[0005] Existing linear lighting fixtures typically use a dual-color extrusion process for their diffuser plates, resulting in a transparent or diffuser material as the light-emitting surface. To secure the diffuser plate to the lamp housing, a soft adhesive is used at the clips to facilitate easier connection through its elasticity.

[0006] However, two-color extrusion is more expensive and the extrusion process is more complex. The resulting buckles are not only limited in application, but also have a relatively long and thick size, making packaging and transportation inconvenient.

[0007] In view of this, it is indeed necessary to improve the existing latching structure of lighting fixtures in order to solve the above problems. Summary of the Invention

[0008] The purpose of this application is to provide a snap-fit ​​structure.

[0009] This application provides a snap-fit ​​structure, including a limiting member and a snap-fit ​​member. The limiting member includes an extension arm and a first extension and a second extension extending from one side of the extension arm and spaced apart from each other. The end of the first extension is provided with a first limiting part, and the end of the second extension is provided with a corresponding second limiting part protruding toward the first extension. The first limiting part is recessed with a first receiving cavity, and a second receiving cavity is formed between the first extension and the second limiting part. The first receiving cavity and the second receiving cavity are connected, and the recessed direction of the first receiving cavity is perpendicular to the recessed direction of the second receiving cavity. The snap-fit ​​member is at least partially received in the second receiving cavity and is pressed by the first limiting part and the second limiting part in different directions, so that the snap-fit ​​member is fixedly connected to the limiting member.

[0010] As a further improvement of this application, the vertical distance between the end of the first limiting part away from the extension arm and the extension arm is greater than the vertical distance between the second limiting part and the extension arm, so that the first limiting part and the second limiting part are misaligned with each other in both the vertical and horizontal directions.

[0011] As a further improvement of this application, the end of the snap-fit ​​member is provided with an extension arm and a snap-fit ​​portion formed at the end of the extension arm. The snap-fit ​​portion is V-shaped and has a first snap-fit ​​arm and a second snap-fit ​​arm extending outward from the extension arm. When the snap-fit ​​member and the limiting member snap-fit ​​together, the first snap-fit ​​arm is received in the second receiving cavity and abuts against the second limiting portion, and the end of the second snap-fit ​​arm is received in the first receiving cavity and abuts against the first limiting portion.

[0012] As a further improvement of this application, a third limiting part is also provided at the connection between the first limiting part and the first extension part. When the snap-fit ​​member and the limiting member snap-fit ​​together, the second snap-fit ​​arm simultaneously abuts against the first limiting part and the third limiting part.

[0013] As a further improvement of this application, the first latching arm is defined to have a first positioning point that abuts against the second limiting part, the second latching arm is defined to have a second positioning point that abuts against the third limiting part, the end of the second latching arm is defined as the third positioning point, the first positioning point is close to the extension arm, and the second positioning point is close to the connection point of the first latching arm and the second latching arm.

[0014] As a further improvement of this application, when the snap-fit ​​member and the limiting member snap together, the second limiting portion fits against the extension arm.

[0015] The purpose of this application is to provide a lamp that not only saves costs but is also compatible with a variety of diffusers and is more convenient for packaging and transportation.

[0016] This application provides a lamp, including a lamp housing and a diffuser plate detachably connected to the lamp housing. The lamp housing and the diffuser plate are connected by a snap-fit ​​structure as described above. The limiting member is integrally formed on both opposite sides of the lamp housing, and the snap-fit ​​member is provided at the end of the diffuser plate.

[0017] As a further improvement of this application, the bottom of the lamp housing is provided with an assembly cavity, the diffuser plate is assembled in the assembly cavity, the snap-fit ​​is V-shaped and perpendicular to the diffuser plate, and the snap-fit ​​and the limiting member cooperate with each other so that the diffuser plate and the lamp housing are snapped together.

[0018] As a further improvement to this application, the diffuser plate and the snap-fit ​​component are integrally formed.

[0019] As a further improvement of this application, the bottom of the lamp housing is provided with an assembly cavity, the diffuser plate is assembled in the assembly cavity, the snap-fit ​​member extends along the same plane as the diffuser plate, so that the diffuser plate has a flat plate structure and is inserted into and fixed in the second receiving cavity between the first extension and the second limiting part.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 3. This application discloses a lamp, including a lamp housing 1 and a diffuser plate 2 detachably connected to the lamp housing 1. The bottom of the lamp housing 1 is provided with an assembly cavity 10, and the diffuser plate 2 is assembled in the assembly cavity 10. The lamp housing 1 and the diffuser plate 2 are connected by a snap-fit ​​structure 3.

[0027] The snap-fit ​​structure 3 includes a limiting member 31 and a snap-fit ​​member 32. The limiting member 31 is disposed on opposite sides of the lamp housing 1, and the snap-fit ​​member 32 is disposed at the end of the diffuser plate 2. Preferably, the limiting member 31 is integrally formed with the lamp housing 1, and the snap-fit ​​member 32 is integrally formed with the diffuser plate 2. Of course, in other embodiments, the limiting member 31 and the snap-fit ​​member 32 can be independent components, and this is not limited.

[0028] Specifically, the limiting member 31 includes an extension arm 311 and a first extension portion 312 and a second extension portion 313 extending from one side of the extension arm 311 and spaced apart from each other. The end of the first extension portion 312 is provided with a first limiting portion 3121, and the end of the second extension portion 313 is provided with a corresponding second limiting portion 3131 protruding toward the first extension portion 312. The first limiting portion 3121 is recessed with a first receiving cavity 31210, and a second receiving cavity 31310 is formed between the first extension portion 312 and the second limiting portion 3131. The first receiving cavity 31210 and the second receiving cavity 31310 are connected, and the recessed direction of the first receiving cavity 31210 and the recessed direction of the second receiving cavity 31310 are perpendicular. The snap-fit ​​member 32 is at least partially received in the second receiving cavity 31310 and is pressed in different directions by the first limiting portion 3121 and the second limiting portion 3131 respectively, so that the snap-fit ​​member 32 is fixedly connected to the limiting member 31.

[0029] In other words, by providing a first limiting part 3121 at the end of the first extension 312, and a corresponding second limiting part 3131 protruding toward the first extension 312 at the end of the second extension 313, the first receiving cavity 31210 recessed in the first limiting part 3121 is connected to the second receiving cavity 31310 formed between the first extension 312 and the second limiting part 3131, so as to receive and engage the snap-fit ​​member 32.

[0030] In this embodiment, the snap-fit ​​member 32 is V-shaped and perpendicular to the diffuser plate 2. The snap-fit ​​member 32 and the limiting member 31 cooperate with each other to snap the diffuser plate 2 and the lamp housing 1 together. At this time, the snap-fit ​​member 32 is simultaneously housed in the first receiving cavity 31210 and the second receiving cavity 31310.

[0031] Optionally, in other embodiments, the snap-fit ​​member 32 extends along the same plane as the diffuser plate 2, such that the diffuser plate 2 has a flat plate structure and is inserted and fixed in the second receiving cavity 31310 between the first extension 312 and the second limiting part 3131. That is to say, the snap-fit ​​structure 3 of this application can be adapted to various forms of diffuser plates 2.

[0032] The vertical distance between the end of the first limiting part 3121 furthest from the extension arm 311 and the extension arm 311 is greater than the vertical distance between the second limiting part 3131 and the extension arm 311, so that the first limiting part 3121 and the second limiting part 3131 are misaligned with each other in both the vertical and horizontal directions. This allows the limiting member 31 to press and lock the locking member 32 in different directions, ultimately achieving the locking of the lamp housing 1 and the diffuser plate 2.

[0033] Specifically, the end of the latching member 32 is provided with an extension arm 321 and a latching portion 322 formed at the end of the extension arm 321. The latching portion 322 is V-shaped and has a first latching arm 3221 and a second latching arm 3222 extending outward from the extension arm 321. When the latching member 32 and the limiting member 31 are latched together, the first latching arm 3221 is received in the second receiving cavity 31310 and abuts against the second limiting portion 3131. The end of the second latching arm 3222 is received in the first receiving cavity 31210 and abuts against the first limiting portion 3121.

[0034] Preferably, the snap-fit ​​portion 322 is in the shape of "<" or ">" to engage with the limiting member 31.

[0035] A third limiting part 3122 is also provided at the connection between the first limiting part 3121 and the first extension part 312. When the snap-fit ​​member 32 and the limiting member 31 snap-fit ​​together, the second snap-fit ​​arm 3222 simultaneously abuts against the first limiting part 3121 and the third limiting part 3122. In this way, through the limiting and pressing of the first limiting part 3121, the second limiting part 3131 and the third limiting part 3122 in different directions, the diffuser plate 2 is firmly snapped onto the lamp housing 1.

[0036] The first latching arm 3221 is defined to have a first positioning point 3223 that abuts against the second limiting part 3131, the second latching arm 3222 is defined to have a second positioning point 3224 that abuts against the third limiting part 3122, and the end of the second latching arm 3222 is defined to be a third positioning point 3225. The first positioning point 3223 is close to the extension arm 321, and the second positioning point 3224 is close to the connection point of the first latching arm 3221 and the second latching arm 3222.

[0037] Preferably, the second limiting part 3131 is fitted with the extension arm 321 so that the first positioning point 3223 is close to the extension arm 321. This makes the engagement of the diffuser plate 2 and the lamp housing 1 more stable.

[0038] Referring to Figures 4 and 5, when the diffuser plate 2 is installed, the snap-fitting of the snap-fitting member 32 and the limiting member 31 prevents the diffuser plate 2 from falling off due to forceful squeezing. Moreover, when the lamp has been used for a long time and the diffuser plate 2 tends to fall downwards, the presence of the limiting member 31 ensures that the diffuser plate 2 remains snapped onto the lamp housing 1 and will not fall downwards, thus enhancing the connection stability between the lamp housing 1 and the diffuser plate 2 and extending the service life of the lamp.

[0039] In summary, the snap-fit ​​structure 3 and the lamp of this application provide a first limiting part 3121 at the end of the first extension 312 and a second limiting part 3131 protruding toward the first extension 312 at the end of the second extension 313, so that the first receiving cavity 31210 recessed in the first limiting part 3121 is connected to the second receiving cavity 31310 formed between the first extension 312 and the second limiting part 3131, thereby adapting to different snap-fit ​​parts 32 and improving the applicability.

[0040] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
