SUMMARY

[0003] The utility model provides a kind of open-mounted down lamp with simple structure, easy installation and disassembly and stable assembly.

[0004] The utility model adopts the technical scheme to solve the above technical problems:

[0005] An open-mounted down lamp includes an outer cylinder and a built-in down lamp. The bottom of the outer cylinder is an light outlet opening. The light outlet opening has a vertical positioning lap wall in the form of a ring. The outer side wall of the built-in down lamp is provided with at least two positioning lap components at intervals. The positioning lap components have elastic lap parts that can be positioned and lapped on the positioning lap wall. The positioning lap wall is provided with mounting gaps corresponding to the number and assembly positions of the positioning lap components, through which the elastic lap parts can pass. The mounting gaps divide the positioning lap wall into multiple positioning lap segments. One positioning lap segment corresponds to one mounting gap. The positioning lap segment, from close to the corresponding mounting gap to far, is sequentially a guide portion, a positioning lap portion, and a limiting portion. The built-in down lamp is installed into the outer cylinder from bottom to top. After the elastic lap parts on the positioning lap components pass through the corresponding mounting gaps, the built-in down lamp is rotated. The elastic lap parts enter the positioning lap portion along the guide portion to complete positioning and lapping, and the limiting portion forms installation limiting.

[0006] The guide portion includes an inlet portion and an outlet portion extending from the corresponding mounting notch to the farthest point. The vertical height between the top surface of the inlet portion and the bottom surface of the outer cylinder gradually increases from the corresponding mounting notch to the farthest point, while the vertical height between the top surface of the outlet portion and the bottom surface of the outer cylinder gradually decreases from the corresponding mounting notch to the farthest point. The highest point is formed at the junction of the top surfaces of the inlet portion and the outlet portion.

[0007] The vertical height between the top surface of the positioning overlap portion and the bottom surface of the outer cylinder is the same everywhere and is equal to the minimum vertical height between the outlet portion and the bottom surface of the outer cylinder.

[0008] The vertical height between the top surface of the limiting part and the bottom surface of the outer cylinder is the same everywhere and is greater than the vertical height between the positioning overlap part and the bottom surface of the outer cylinder.

[0009] The positioning and overlapping component includes a mounting part for fixed installation with the outer wall of the built-in downlight. The mounting part includes a vertically arranged mounting plate, which is detachably and fixedly connected to the outer wall of the built-in downlight via a detachable mounting component.

[0010] The mounting component is a mounting screw. The corresponding mounting position of the built-in downlight is provided with a matching mounting screw hole. The mounting plate is screwed into the corresponding mounting screw hole by the mounting screw to achieve a detachable and fixed connection with the outer wall of the built-in downlight.

[0011] The mounting plate is provided with a protrusion that protrudes toward the inner sidewall of the built-in downlight.

[0012] There are three protrusions, which are arranged in a triangular pattern.

[0013] The elastic overlap portion is an overlap plate, the inner end of which is connected to the mounting plate as a fixed end, and the outer end of which is a free end.

[0014] The free end is positioned higher than the fixed end in the vertical direction, and the free end and the horizontal plane containing the fixed end form an acute angle.

[0015] The acute angle is 5°.

[0016] The two opposite sides of the overlapping plate are bent upward to form a side protection section.

[0017] The positioning overlap wall is connected to the outer cylinder through a horizontally arranged annular connecting wall. The annular connecting wall is located inside the light-emitting opening. The annular connecting wall has an installation opening corresponding to the installation notch for the elastic overlap part to pass through. The built-in downlight has a face ring. The elastic overlap part is spaced above the face ring. After installation, the face ring is attached to the bottom of the annular connecting wall.

[0018] The overlapping plate and the mounting plate are an integral part, and the mounting plate is bent to form the elastic overlapping part.

[0019] Compared with the existing technology, the advantages of this utility model are: simple structure, no need for additional tools, can easily and quickly achieve a stable connection and installation between the built-in downlight and the outer cylinder, and the assembly efficiency is improved by at least 50% compared with the traditional structure; the top surface design of the positioning overlap section has a specific screw-in installation curve, and the vibration resistance is significantly better than the traditional structure. In addition, with this structure, when the built-in downlight needs to be maintained or replaced, it is not necessary to disassemble the entire outer cylinder together, making maintenance and replacement more convenient.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] As shown in the figure, a surface-mounted downlight includes an outer cylindrical body 1 and an inner downlight 2. The bottom of the outer cylindrical body 1 is a light-emitting opening 11, and the light-emitting opening 11 has a vertically arranged annular positioning overlapping wall 10. At least two positioning overlapping parts 3 are spaced apart on the outer side wall of the inner downlight 2. The positioning overlapping parts 3 have elastic overlapping portions 30 that can be positioned and overlapped on the positioning overlapping wall 10. The positioning overlapping wall 10 is correspondingly provided with mounting notches 101 that match the number and assembly position of the positioning overlapping parts 3 and allow the elastic overlapping portions 30 to pass through. The mounting notches 101 divide the positioning overlapping wall 10 into multiple Each positioning overlap section 102 corresponds to an installation notch 101. The positioning overlap sections 102, from the closest to the corresponding installation notch 101 to the furthest away, are a guide portion 1021, a positioning overlap portion 1022, and a limiting portion 1023. The built-in downlight 2 is installed into the outer cylinder 1 from bottom to top. After the elastic overlap portion 30 on the positioning overlap component 3 passes through the corresponding installation notch 101, the built-in downlight 2 is rotated so that the elastic overlap portion 30 enters the positioning overlap portion 1022 along the guide portion 1021 to complete the positioning overlap, and is limited by the limiting portion 1023.

[0032] In this specific embodiment, there are two positioning overlap parts 3, which are evenly spaced apart. Considering manufacturing costs, the two evenly spaced positioning overlap parts 1022 are sufficient to ensure stable positioning and installation of the built-in downlight 2 within the outer cylinder 1.

[0033] In this specific embodiment, the guide portion 1021 includes an inlet portion 10211 and an outlet portion 10212 extending from the corresponding mounting notch 101 to the farthest point. The vertical height between the top surface of the inlet portion 10211 and the bottom surface of the outer cylinder 1 gradually increases from the corresponding mounting notch 101 to the farthest point, while the vertical height between the top surface of the outlet portion 10212 and the bottom surface of the outer cylinder 1 gradually decreases from the corresponding mounting notch 101 to the farthest point. The highest point H is formed at the junction of the top surface of the inlet portion 10211 and the top surface of the outlet portion 10212. During installation, by rotating the built-in downlight 2, the elastic overlapping part 30 gradually rises along the top surface of the inlet portion 10211 to the highest point H, and then gradually falls back along the top surface of the outlet portion 10212 until the positioning overlapping part 1022 achieves positioning overlap. The highest point H cooperates with the limiting part 1023 to achieve stable limiting installation. During disassembly, by rotating the built-in downlight 2, the elastic overlapping part 30 gradually rises along the top surface of the outlet portion 10212 to the highest point H, and then gradually falls back along the top surface of the inlet portion 10211. The inlet portion 10211 facilitates inlet installation, the outlet portion 10212 facilitates outlet disassembly, and the highest point H is used to achieve limiting in another direction.

[0034] In this specific embodiment, the vertical height between the top surface of the positioning overlap portion 1022 and the bottom surface of the outer cylinder 1 is the same everywhere and equal to the minimum vertical height between the leading portion 10212 and the bottom surface of the outer cylinder 1. This makes the top surface of the positioning overlap portion 1022 a platform portion that flows smoothly downwards, facilitating the stable overlapping installation of the elastic overlap portion 30.

[0035] In this specific embodiment, the minimum vertical height between the top surface of the inlet portion 10211 and the bottom surface of the outer cylinder 1 is less than the vertical height between the top surface of the positioning overlap portion 1022 and the bottom surface of the outer cylinder 1. The height of the positioning overlap portion 1022 is designed to be the optimal positioning and installation height for the built-in downlight 2 and the outer cylinder 1. Therefore, the design makes the minimum vertical height of the top surface of the inlet portion 10211 less than the height of the positioning overlap portion 1022, which facilitates the insertion of the elastic overlap portion 30 after passing through the installation notch 101.

[0036] In this specific embodiment, the vertical height between the top surface of the limiting portion 1023 and the bottom surface of the outer cylinder 1 is the same everywhere and is greater than the vertical height between the positioning overlap portion 1022 and the bottom surface of the outer cylinder 1. This allows the limiting portion 1023 to provide a stable limiting function.

[0037] In this specific embodiment, the positioning and overlapping component 3 includes a mounting portion for fixed installation with the outer wall of the built-in downlight 2. The mounting portion includes a vertically arranged mounting plate 31, which is detachably and fixedly connected to the outer wall of the built-in downlight 2 via a detachable mounting member 4. The structure is simple and easy to manufacture.

[0038] In this specific embodiment, the mounting component 4 is a mounting screw, and the corresponding mounting position of the built-in downlight 2 is provided with a matching mounting screw hole (not shown in the figure). The mounting plate 31 is screwed into the corresponding mounting screw hole by the mounting screw to achieve a detachable and fixed connection with the outer wall of the built-in downlight 2. The structure is simple, the cost is low, and it is easy to install and disassemble.

[0039] In this specific embodiment, the mounting plate 31 is provided with a protrusion 311 that protrudes towards the inner sidewall of the built-in downlight 2. During pre-installation, the protrusion 311 is first attached to the outer sidewall mounting location of the built-in downlight 2, which can effectively prevent the mounting plate 31 from rotating or shifting when the mounting screws are tightened.

[0040] In this specific embodiment, there are three protrusions 311, which are arranged in a triangular pattern. The triangular arrangement of the three protrusions 311 provides more stable pre-installation anti-rotation.

[0041] In this specific embodiment, the elastic overlapping portion 30 is an overlapping plate, with its inner end connected to the mounting plate 31 as a fixed end, and its outer end as a free end. This simple structure ensures that the elastic overlapping portion 30 has stable elasticity.

[0042] In this specific embodiment, the free end is positioned higher than the fixed end in the vertical direction, and the horizontal plane containing the free end and the fixed end forms an acute angle α. This allows for manufacturing errors and facilitates snap-fit ​​installation.

[0043] In this specific embodiment, the acute angle α is 5°. It is set to a 5-degree angle with the horizontal plane, ensuring that the gap during insertion and the interference fit after insertion are close to each other, thus guaranteeing that it can be inserted and locked in place even with a certain margin of error.

[0044] In this specific embodiment, the opposite sides of the overlapping plate are bent upwards to form side protection portions 301. The side protection portions 301 provide side impact protection and strength enhancement.

[0045] In this specific embodiment, the positioning overlapping wall 10 is connected to the outer cylinder 1 via a horizontally arranged annular connecting wall 13. The annular connecting wall 13 is disposed within the light-emitting opening 11. The annular connecting wall 13 has an installation opening 131 corresponding to the installation notch 101, allowing the elastic overlapping portion 30 to pass through. The built-in downlight 2 has a face ring 21, and the elastic overlapping portions 30 are spaced apart above the face ring 21. After installation, the face ring 21 is abutted against the lower part of the annular connecting wall 13. This allows the bottom of the built-in downlight 2 to completely cover the light-emitting opening 11, resulting in a compact and aesthetically pleasing structure.

[0046] In this specific embodiment, the overlapping plate and the mounting plate 31 are an integral piece. The mounting plate 31 is bent to form an elastic overlapping portion 30. This integral piece is made of elastic spring steel. It is easy to manufacture, has stable elasticity, and facilitates the installation of the mounting portion and the positioning and overlapping installation of the overlapping portion.
