Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a downlight housing that is easy to assemble. Background Technology

[0002] Downlights, as commonly used indoor lighting fixtures, not only bear the core function of housing the internal light source and driving components, but their face rings, as the exposed part of the housing, also directly affect the compatibility of the fixture with the interior decoration style. With the diversification of consumer aesthetic demands and the differentiation of decoration scenarios, downlight housings need to be matched with face rings of different styles and sizes to meet the decorative needs of different spaces. However, existing traditional one-piece molded downlight housings cannot have their face rings replaced. If the decoration style needs to be adjusted, the entire fixture must be replaced, resulting in high operating costs and resource waste. On the other hand, most existing detachable downlight housings are fixed with bolts, and the face rings are a fixed matching design with the housing. Replacing the face ring requires tools for disassembly, which is cumbersome. Furthermore, the compatibility between different sizes of face rings and housings is poor, making flexible replacement difficult. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a downlight housing that is easy to assemble.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A downlight housing that is easy to assemble includes a lamp housing and a face ring shell detachably disposed at the front end of the lamp housing. The face ring shell includes a circular baffle. A face ring is disposed on the outer side of the front end of the circular baffle, and a limiting protrusion is disposed on the inner side. The front end of the lamp housing is disposed inside the circular baffle and abuts against the limiting protrusion. There are mounting plates for mounting spring clips symmetrically arranged on the left and right sides of the circular baffle. A flipping hook is rotatably mounted on the mounting plate. A flange seat that cooperates with the flipping hook is disposed on the outer side of the lamp housing. The flipping hook can flip and hook onto the rear end of the flange seat, thereby keeping the front end of the lamp housing abutting against the limiting protrusion.

[0006] In some embodiments, slots are provided on both the left and right sides of the annular baffle, and one end of the mounting plate is inserted into the slot and fixed by a first screw.

[0007] In some embodiments, the flipping hook includes a base plate and a bent plate disposed at one end of the base plate. The other end of the base plate is rotatably connected to the mounting plate by a rivet. The base plate can drive the bent plate to rotate around the rivet so that the bent plate hooks onto the rear end of the flange seat.

[0008] In some embodiments, the rear end face of the flange seat is provided with an arc-shaped positioning groove that cooperates with the bending plate, and the end face of the bending plate that is hooked into the arc-shaped positioning groove has an arc-shaped surface structure.

[0009] In some embodiments, an elastic hook is provided on the annular baffle, and a vertical protrusion that cooperates with the elastic hook is provided on the lamp housing. When the elastic hook is hooked onto the vertical protrusion, the front end of the lamp housing remains against the limiting protrusion.

[0010] In some embodiments, a longitudinal guide groove for guiding the installation of the vertical protrusion is provided on the annular baffle, and the elastic hook is disposed in the longitudinal guide groove.

[0011] In some embodiments, a guide slope is provided at the opening end of the longitudinal guide groove.

[0012] In some embodiments, the annular baffle, face ring, limiting protrusion ring, and elastic hook are integrally formed from plastic material.

[0013] In some embodiments, the lamp housing includes a heat sink shell connected and mounted by a plurality of second screws and a lamp shade cylinder disposed at the front end of the heat sink shell, and the flange seat is disposed on the heat sink shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the cooperation structure between the flip hook and the flange seat enables quick and detachable connection between the face ring shell and the lamp housing. No special tools are required; the face ring shell can be disassembled and assembled simply by manually flipping the hook. Face rings of different styles, materials, and sizes can be precisely matched with the same lamp housing by matching the corresponding face ring shell. Users can change the face ring at any time according to the decoration style and usage needs. The operation is simple and efficient, and there is no need to replace the entire lamp, which greatly reduces the cost of use and meets diverse decoration needs. Attached Figure Description

[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] like Figures 1-7 The diagram shows an easy-to-assemble downlight housing, comprising a lamp housing 1 and a face ring shell 2 detachably disposed at the front end of the lamp housing 1. The face ring shell 2 includes a circular baffle 3, a face ring 4 disposed on the outer side of the front end of the circular baffle 3, and a limiting protrusion ring 5 disposed on the inner side. The front end of the lamp housing 1 is disposed inside the circular baffle 3 and abuts against the limiting protrusion ring 5. There are mounting plates 6 symmetrically arranged on the circular baffle 3 for mounting spring clips 10. A flipping hook 7 is rotatably mounted on the mounting plate 6. A flange seat 8 that cooperates with the flipping hook 7 is disposed on the outer side of the lamp housing 1. The flipping hook 7 can flip and hook onto the rear end of the flange seat 8, thereby keeping the front end of the lamp housing 1 abutting against the limiting protrusion ring 5.

[0024] During assembly, first align the front end of the lamp housing 1 with the inner side of the annular baffle 3 of the face ring shell 2, and push it axially until the front end of the lamp housing 1 abuts against the limiting protrusion 5. At this time, the limiting protrusion 5 forms an axial limit on the lamp housing 1, ensuring that the relative positions of the two are accurate and avoiding installation misalignment. At the same time, the flange seat 8 on the outer side of the lamp housing is put into place synchronously with the lamp housing 1, and its position corresponds precisely to the mounting plate 6 and the flip hook 7 on the annular baffle 3. Manually flip the flip hook 7 on the mounting plate 6 upward. Since the flip hook 7 and the mounting plate 6 are rotatably connected, during the flipping process, the front end of the hook gradually approaches and engages with the rear end of the flange seat 8. The symmetrical hooking of the two left and right flipping hooks 7 creates a bidirectional locking force, firmly fixing the lamp housing 1 inside the face ring shell 2, ensuring that the front end of the lamp housing 1 always abuts against the limiting protrusion ring 5, achieving a tight fit and fixation between the two; at the same time, the spring clip 10 installation position reserved on the mounting plate 6 allows for the subsequent assembly of spring clips to meet the overall ceiling installation requirements of the lamp, without affecting the connection stability between the face ring shell and the lamp housing.

[0025] When disassembly or maintenance is required, manually flip the hook 7 downwards and in the opposite direction to release it from the constraint of the flange seat 8 and release the locking force on the lamp housing 1. At this time, the lamp housing 1 can be directly pulled out axially from the inner ring baffle 3 to complete the quick separation of the face ring shell 2 and the lamp housing 1 without the need to disassemble other components.

[0026] Furthermore, slots 21 are provided on both the left and right sides of the annular baffle 3, and one end of the mounting plate 6 is inserted into the slot 21 and fixed by the first screw 22.

[0027] When assembling the mounting plate 6 with the ring shell 2, align one end of the mounting plate 6 with the pre-set slots 21 on the left and right sides of the annular baffle 3, and insert it along the axial direction of the slots 21 until the inserted end of the mounting plate 6 fits against the bottom of the slot 21. The shape of the slot 21 precisely matches the end structure of the mounting plate 6, which can provide radial limiting and positioning for the mounting plate 6, ensuring that the installation height and horizontal position of the two mounting plates 6 are completely symmetrical, providing a basis for the precise fit between the flip hook 7 and the flange seat 8. After the mounting plate 6 is inserted into the slot 21, the first screw 22 passes through the pre-set screw holes on the mounting plate 6 and the annular baffle 3 to firmly fix the mounting plate 6 in the slot 21. The tightening force of the first screw 22 makes the mounting plate 6 and the annular baffle 3 form a rigid connection, preventing the mounting plate 6 from loosening, shifting or falling off during use, while ensuring that the position of the pivot hole on the mounting plate 6 for installing the flip hook 7 is accurate, ensuring that the flip hook 7 rotates smoothly and corresponds accurately with the flange seat 8 of the lamp housing 1.

[0028] Of course, before assembling the mounting plate 6 and the face ring shell 2, the spring clip 10 can be pre-installed on the mounting plate 6.

[0029] In this utility model, the flip hook 7 includes a base plate 31 and a bending plate 32 disposed at one end of the base plate 31. The other end of the base plate 31 is rotatably connected to the mounting plate 6 by a rivet 33. The base plate 31 can drive the bending plate 32 to rotate around the rivet 33 so that the bending plate 32 hooks onto the rear end of the flange seat 8. The rear end face of the flange seat 8 is provided with an arc-shaped positioning groove 41 that cooperates with the bending plate 32. The end face of the bending plate 32 hooking into the arc-shaped positioning groove 41 has an arc-shaped surface structure.

[0030] Specifically, firstly, the other end of the base plate 31 of the flip hook 7 is inserted into the preset hole of the mounting plate 6 through the rivet 33, forming a rotatable movable connection structure, ensuring that the base plate 31 can drive the bending plate 32 to rotate flexibly around the rivet 33, and that the rotation process is free from jamming; at this time, the arc-shaped end face of the bending plate 32 corresponds to the position of the arc-shaped positioning groove 41 on the rear end face of the flange seat 8; after the lamp housing 1 is pushed into the face ring shell 2 and abuts against the limiting protrusion 5, the base plate 31 is manually pushed so that it rotates around the rivet 33 towards the flange seat 8, driving the bending plate 32 to rotate synchronously; due to the hook end face of the bending plate 32 The flange seat 8 has an arc-shaped surface structure, and the rear end face of the flange seat 8 is provided with a matching arc-shaped positioning groove 41. During the rotation of the bending plate 32, the arc-shaped end face can be smoothly inserted into the arc-shaped positioning groove 41 to achieve precise positioning and avoid hook offset. After the bending plate 32 is fully inserted into the arc-shaped positioning groove 41, the arc-shaped surface and the inner wall of the groove are tightly fitted to form a locking structure with surface contact. At the same time, the rotational connection characteristics of the rivet 33 keep the substrate 31 in a stable stress state. With the left and right symmetrical flipping hooks 7, a bidirectional symmetrical locking force is formed on the flange seat 8 to ensure that the lamp housing 1 and the face ring shell 2 are tightly connected.

[0031] See Figure 3 , Figure 5 , Figure 7 As shown, an elastic hook 51 is provided on the annular baffle 3, and a vertical protrusion 52 that cooperates with the elastic hook 51 is provided on the lamp housing 1. When the elastic hook 51 is hooked onto the vertical protrusion 52, the front end of the lamp housing 1 remains against the limiting protrusion 5. A longitudinal guide groove 61 for guiding the installation of the vertical protrusion 52 is provided on the annular baffle 3, and the elastic hook 51 is provided in the longitudinal guide groove 61. A guide slope 71 is provided at the opening end of the longitudinal guide groove 61.

[0032] When assembling the lamp housing 1 and the face ring shell 2, first align the vertical protrusion 52 on the lamp housing 1 with the opening end of the longitudinal guide groove 61 on the circular baffle 3. Since the opening end of the longitudinal guide groove 61 is provided with a guide slope 71, the vertical protrusion 52 will smoothly slide into the longitudinal guide groove 61 under the guidance of the guide slope 71, without the need for deliberate alignment, thus achieving rapid pre-positioning. The longitudinal guide groove 61 forms a radial constraint on the vertical protrusion 52, ensuring that the lamp housing 1 is pushed in smoothly along the axial direction, avoiding left and right deviations during installation, and providing double protection for the precise cooperation between the subsequent flipping hook 7 and the flange seat 8. As the lamp housing 1 is continuously pushed in, the vertical protrusion 52 moves axially along the longitudinal guide groove 61 until the front end of the lamp housing 1 abuts against the limiting protrusion 5. During this process, the vertical protrusion 52 will squeeze the elastic hook 51 in the longitudinal guide groove 61, causing the elastic hook 51 to undergo elastic deformation and avoid the inner side of the guide groove; when the lamp housing 1 is fully in place, the vertical protrusion 52 moves to the engaging position of the elastic hook 51, and the elastic hook 51 resets under its own elastic restoring force, automatically hooking onto the outside of the vertical protrusion 52, forming the first locking fixation; after the elastic hook 51 engages with the vertical protrusion 52, the second locking is achieved by flipping the hook 7 to hook onto the flange seat 8; together, they ensure the all-round stability of the connection between the lamp housing 1 and the face ring shell 2.

[0033] Two sets of elastic hooks 51 and vertical protrusions 52 are provided, respectively located between the two spring clips 10.

[0034] In this invention, the annular baffle 3, the face ring 4, the limiting protrusion 5, and the elastic hook 51 are all integrally formed from plastic material; an integral molding process (preferably injection molding, suitable for plastic material) is adopted to process the annular baffle 3, the face ring 4, the limiting protrusion 5, and the elastic hook 51 in one step; when the plastic material is preferred, a plastic material with good elasticity, toughness, and formability (such as ABS, PC, PP, etc.) is selected.

[0035] In this utility model, the lamp housing 1 includes a heat sink 91 connected and installed by a plurality of second screws 93 and a lamp cover cylinder 92 disposed at the front end of the heat sink 91, and the flange seat 8 is disposed on the heat sink 91.

[0036] The heat sink 91 is dedicated to heat dissipation and can be made of aluminum alloy with excellent thermal conductivity. It can quickly dissipate the heat generated by the light source during operation through heat dissipation fins. The lampshade 92 is used to support the light source mounting position and light transmission structure. It can be made of transparent, frosted or anti-glare material according to lighting needs. The two have clear division of labor and are firmly connected by the second screw 93, which ensures both heat dissipation efficiency and stable lighting function.
