Description

Technical Field

[0001] The utility model relates to the technical field of downlight installation, in particular to a downlight installation structure and a downlight device adapted to a large opening. Background Art

[0002] When installing a downlight, you first need to drill a hole in the ceiling, then bend the elastic clip on the downlight backwards to insert the rear end of the downlight into the hole until the distal end of the elastic clip enters the interior of the ceiling. At this time, the elastic clip is released, and the elastic clip rebounds, and the distal end of the elastic clip abuts the inner surface of the ceiling, driving the downlight upward until the front flange of the downlight abuts the outer surface of the ceiling, completing the installation of the downlight. Therefore, when installing a current downlight, the size of the hole in the ceiling must match the size of the downlight, so that the elastic clip of the downlight can abut the inner surface of the ceiling and the front flange of the downlight can be clipped to the outer surface of the ceiling. However, in many cases, the size of the hole in the ceiling is pre-set, and there is a possibility that the hole size is too large, making the downlight impossible to install. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a downlight installation structure and a downlight device adapted to large openings, which can enable a small-sized downlight to be adapted and installed in a large-sized opening.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] Technical Solution 1: A downlight mounting structure suitable for large openings, which is used to install the downlight into an opening pre-opened in a base, and comprises: a first fixing ring, which is an elastic annular sheet with its ends disconnected and adapted to bend and deform so that its ends are separated so as to pass through the opening from the first side of the base to the second side of the base; a second fixing ring, which is an annular sheet connected end to end and adapted to be fastened to the first fixing ring via fasteners so as to be clamped and fixed to the base in cooperation with the first fixing ring; the inner edges of the first and second fixing rings cooperate to form a mounting hole suitable for installation of the downlight.

[0006] Technical solution 2 based on technical solution 1: also includes a face ring, which is suitable for being snap-fitted with the front end flange of the downlight and covering the second fixing ring when the downlight is installed in the mounting hole.

[0007] Technical solution three based on technical solution two: the second fixing ring forms a first abutment portion and a second abutment portion in the axial direction; the first abutment portion is located on the inner side of the second abutment portion and is higher than the second abutment portion to be close to the first fixing ring; the second abutment portion is suitable for abutting to the first side of the base.

[0008] Technical solution four based on technical solution three: the first fixing ring is provided with at least two symmetrically positioned first holes along its axial direction, the second fixing ring is provided with a second hole corresponding to the first hole one by one on the first abutting portion along its axial direction, and the fastener is suitable for fastening the first fixing ring and the second fixing ring through the first hole and the second hole.

[0009] Technical solution five based on technical solution four: the second hole is arc-shaped and includes an expansion section and a reduction section that are interconnected. The size of the expansion section is larger than the reduction section, so that the fastener passes through the second hole from the expansion section and is tightly fitted with the second fixing ring in the reduction section.

[0010] Technical solution six based on technical solution five: the fastener is suitable for threaded engagement with the first hole.

[0011] Technical solution seven based on technical solution six: the first fixing ring and the second fixing ring are made of metal or plastic.

[0012] In addition, the present invention also provides technical solution eight: a downlight device, which includes a downlight, and also includes a first fixing ring, a second fixing ring and a fastener in the downlight mounting structure adapted to the large opening as described in any one of technical solutions one to seven, and is suitable for installing the downlight into an opening pre-opened in the base through the mounting structure.

[0013] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0014] Technical solution 1 provides a downlight mounting structure that is adapted to a large opening, which is used to install the downlight into an opening pre-opened in a base, and includes a first fixing ring, a second fixing ring and a fastener. The first fixing ring is an elastic annular sheet that is disconnected at both ends. Since the first fixing ring is disconnected at both ends, the first fixing ring can be bent and deformed so that the ends are separated from each other, and the head end or tail end of the first fixing ring is inserted into the opening until the first fixing ring passes through the opening from the first side of the base into the second side of the base, at which time the first fixing ring recovers its deformation and becomes annular again; then the second fixing ring is fastened to the first fixing ring by a fastener, thereby fixing the first and second fixing rings on the base, at which time the inner edges of the first and second fixing rings cooperate to form a mounting hole that is adapted to the size of the downlight, and the downlight can be installed on the base through the mounting hole, so that a small-sized downlight can be adapted to a large-sized opening, thereby improving the installation adaptation range of the downlight.

[0015] In the second technical solution, a face ring is provided, which can be fixed by snapping together with the downlight, and when the downlight is installed in the mounting hole, it covers the second fixing ring, so that the appearance of the entire downlight after installation is more integrated.

[0016] In technical solution three, a first abutting portion and a second abutting portion are provided on the second fixing ring, and the first abutting portion is higher than the second abutting portion. When installing the second fixing ring, the first abutting portion can be inserted into the opening on the base, and the second abutting portion can be abutted against the first side of the base, so as to facilitate positioning the second fixing ring on the base, and also allow the second fixing ring to be closer to the first fixing ring, so as to facilitate fastening the first fixing ring and the second fixing ring by fasteners.

[0017] In technical solution four, a first hole is provided on the first fixing ring, and a second hole is provided on the second fixing ring, and the fastener can fasten the first fixing ring and the second fixing ring by passing through the first hole and the second hole; the second hole is provided on the first abutting portion of the first fixing ring, and the first abutting portion is closer to the first fixing ring, which can reduce the distance between the first hole and the second hole, and can reduce the deformation of the first fixing ring and the second fixing ring when fastened by the fastener.

[0018] In technical solution five, the second hole is arc-shaped and includes a connected expansion section and a reduction section. During installation, the fastener can be locked to the first fixing ring first, and then the first fixing ring can be passed through the opening. At this time, the fastener extends from the first fixing ring. During the installation of the second fixing ring to the opening, the fastener can first enter the expansion section of the second hole, and then the second fixing ring can be rotated to make the fastener enter the reduction section of the second hole. At this time, the end cap of the fastener can be stuck on the second fixing ring, so that the first fixing ring and the second fixing ring can be fastened and connected through the fastener.

[0019] In technical solution six, the fastener is directly threaded into the first hole, making it convenient to fasten the first fixing ring and the second fixing ring together through the fastener.

[0020] In technical solution seven, the first fixing ring and the second fixing ring are made of metal or plastic, and have good elastic deformation performance and structural strength.

[0021] Technical Solution Eight provides a downlight device, which includes the first fixing ring, the second fixing ring and the fasteners in the above-mentioned downlight mounting structure adapted to large openings, and is suitable for installing the downlight into an opening pre-opened in the base through the mounting structure, so that a small-sized downlight can be adapted to a large-sized opening, thereby improving the installation adaptation range of the downlight.

[0034] Example 1

[0035] Reference Figure 1 , the utility model embodiment 1 provides a downlight installation structure adapted to a large opening, which is used to install the downlight 1 into the opening 3 pre-opened in the base 2. Among them, the structure of the base 2 refers to Figure 2 An opening 3 is provided on the base 2. In practical applications, the base 2 is generally a suspended ceiling, and the opening 3 is provided on the suspended ceiling. The first side 5 of the base 2 is the outer side, and the second side 6 of the base 2 is the inner side. Corresponding to the suspended ceiling, the first side 5 is the bottom side, and the second side 6 is the top side.

[0036] Reference Figure 1 The installation structure of the downlight 1 mainly includes a first fixing ring 4, a second fixing ring 7, a fastener 8 and a surface ring 10.

[0037] The first fixing ring 4 is a flexible, annular sheet that is disconnected at both ends and is adapted to bend and deform to separate its ends so as to pass from the first side 5 of the base 2 through the opening 3 and into the second side 6 of the base 2. The second fixing ring 7 is a thin, annular sheet that is connected end to end and adapted to be fastened to the first fixing ring 4 via fasteners 8, thereby cooperating with the first fixing ring 4 to clamp and secure it to the base 2. The inner edges of the first and second fixing rings 4, 7, cooperate to form a mounting hole 9 suitable for mounting the downlight 1. A face ring 10 is adapted to engage with the front flange of the downlight 1 and cover the second fixing ring 7 when the downlight 1 is installed in the mounting hole 9.

[0038] Specifically, the first fixing ring 4 will be described first. The first fixing ring 4 is a ring-shaped thin sheet that is disconnected at both ends. The disconnection here means that although the first fixing ring 4 forms a ring-shaped structure in shape, there is a disconnection in the middle of the ring structure. Combined with the elastic deformation ability of the first fixing ring 4 itself, the first fixing ring 4 can be deformed from the original ring shape into a long strip structure by bending its head and tail ends in directions away from each other. At the same time, the width of the first fixing ring 4, that is, the difference between the outer diameter and the inner diameter, is smaller than the original opening 3 on the base 2. At the same time, when the base 2 is used as a ceiling, its thickness is relatively thin. Therefore, after the first fixing ring 4 is bent into a long strip, one end of the first fixing ring 4 is first inserted into the opening 3, and then the first fixing ring 4 is sent from the first side 5 of the base 2 to the second side 6 of the base 2. When the first fixing ring 4 completely enters the second side 6 of the base 2, the first fixing ring 4 will return to a ring structure due to its own elastic deformation ability and just sit at the position of the opening 3. The inner diameter of the first fixing ring 4 is smaller than the diameter of the opening 3, which is equivalent to reducing the diameter of the opening 3 on the second side 6 of the base 2.

[0039] Next, the second fixing ring 7 is described. The second fixing ring 7 is a ring-shaped thin sheet connected end to end. The end to end connection here means that the second fixing ring 7 is a complete ring structure and cannot be disconnected in the middle. Figure 1 The second fixing ring 7 forms a first abutting portion 11 and a second abutting portion 12 in the axial direction; the first abutting portion 11 is located on the inner side of the second abutting portion 12 and is higher than the second abutting portion 12 to be closer to the first fixing ring 4; the second abutting portion 12 is suitable for abutting against the first side 5 of the base 2. Specifically, the second abutting portion 12 of the second fixing ring 7 is located on the outer ring, and the first abutting portion 11 is located on the inner ring, and the two cooperate to form a stepped structure. The first abutting portion 11 enables the second fixing ring 7 to be inserted into the opening 3 of the base 2, facilitating the positioning of the second fixing ring 7; the second abutting portion 12 has a larger area than the first abutting portion 11, which can increase the abutting area with the first side 5 of the base 2, making the connection between the second fixing ring 7 and the first fixing ring 4 more stable.

[0040] The first fixing ring 4 is provided with at least two symmetrically positioned first holes 13 extending axially therethrough. The second fixing ring 7 is provided with second holes 14 extending axially therethrough on the first abutting portion 11, corresponding one-to-one with the first holes 13. The fastener 8 is adapted to securely connect the first fixing ring 4 and the second fixing ring 7 via the first and second holes 13, 14. The second hole 14 is arcuate and includes an interconnected enlarged section 15 and a narrowed section 16. The enlarged section 15 is larger than the narrowed section 16, enabling the fastener 8 to pass through the enlarged section 15, through the second hole 14, and securely engage with the second fixing ring 7 at the narrowed section 16.

[0041] Specifically, the first fixing ring 4 and the second fixing ring 7 are fastened together by a fastener 8. The first fixing ring 4 is located on the second side 6 of the base 2, and the second fixing ring 7 is located on the first side 5 of the base 2. After being fastened together by the fastener 8, the two can cooperate with each other to clamp the base 2, thereby firmly fixing the first fixing ring 4 and the second fixing ring 7 on the base 2, and forming a mounting hole 9 through the inner edges of the first fixing ring 4 and the second fixing ring 7. The aperture of the mounting hole 9 is smaller than the diameter of the original opening 3 on the base 2, and can be adapted to the size of the corresponding downlight 1.

[0042] Two axially penetrating and symmetrically positioned first holes 13 are provided on the first fixing ring 4. Corresponding to the two first holes 13, two second holes 14 are provided on the first abutting portion 11 of the second fixing ring 7. The fastener 8 can fasten the first fixing ring 4 to the second fixing ring 7 through the corresponding first holes 13 and second holes 14. The first hole 13 is a circular hole, and the fastener 8 is suitable for threaded engagement with the first hole 13. Therefore, when locking, the fastener 8 can be directly screwed to the first hole 13. The second hole 14 is arc-shaped and includes an enlarged section 15 and a reduced section 16 that are interconnected. The size of the enlarged section 15 allows the end cap of the fastener 8 to pass through, while the size of the reduced section 16 is smaller than the size of the end cap of the fastener 8. Therefore, when the fastener 8 enters the position of the reduced section 16, the end cap of the fastener 8 can clamp the second fixing ring 7. During installation, the fastener 8 is first screwed to the first fixing ring 4. After the first fixing ring 4 is installed on the second side 6 of the base 2, the fastener 8 will hang down from the first fixing ring 4. At this time, the second fixing ring 7 can be put on the fastener 8. Then the second fixing ring 7 is rotated to make the fastener 8 enter the narrowing section 16 from the enlarged section 15 of the second hole 14. Then the fastener 8 can be tightened.

[0043] The first fixing ring 4 and the second fixing ring 7 are made of metal or plastic. They can have good elastic deformation performance and structural strength. Preferably, the first fixing ring 4 can be made of metal, such as iron, and the second fixing ring 7 can be made of plastic, such as high-strength engineering plastic.

[0044] Then refer to Figure 1 , Figure 1 The structure of the face ring 10 is shown in FIG. The face ring 10 is also annular, and its outer edge extends upward to form a sidewall. At its inner edge, it also rises upward to form a step-like structure. A groove for the second fixing ring 7 to be installed is formed between the outer sidewall of the face ring 10 and the inner step of the face ring 10. The face ring 10 can cover the second fixing ring 7 through this groove. At the same time, the step-like structure at the inner edge of the face ring 10 can adapt to the front flange of the downlight 1. After the downlight 1 passes through the hole in the middle of the face ring 10 from bottom to top with its rear end, the front flange of the downlight 1 just falls into the step-like structure at the inner edge of the face ring 10, thereby preventing the face ring 10 from falling and preventing the front flange of the downlight 1 from protruding from the surface of the first side 5 of the base 2.

[0045] Reference Figure 3 and Figure 4 When installing the downlight 1, first install the first fixing ring 4 into the second side 6 of the base 2, and then fasten the second fixing ring 7 to the first fixing ring 4 through the fastener 8, then put the face ring 10 into the downlight 1, so that the face ring 10 is stuck on the front end flange of the downlight 1, and then bend the elastic buckle on the downlight 1 backward, and install the downlight 1 into the smaller mounting hole 9 formed by the first fixing ring 4 and the second fixing ring 7, and then release the elastic buckle. Under the action of the elastic buckle, the downlight 1 moves up, and the face ring 10 is clamped on the first side 5 of the base 2. At the same time, the elastic buckle is buckled into the second side 6 of the base 2 or the first fixing ring 4, and the installation of the downlight 1 is completed.

[0046] The utility model provides a downlight installation structure adapted for a large opening, which is used to install a downlight 1 into an opening 3 pre-opened in a base 2, and includes a first fixing ring 4, a second fixing ring 7 and a fastener 8. The first fixing ring 4 is a ring-shaped sheet with an elasticity that is disconnected at both ends. Since the first fixing ring 4 is disconnected at both ends, the first fixing ring 4 can be bent and deformed so that the ends are separated from each other, and the head end or tail end of the first fixing ring 4 is inserted into the opening 3 until the first fixing ring 4 passes through the opening 3 from the first side 5 of the base 2 and enters the base 2. On the second side 6 of the base 2, the first fixing ring 4 recovers its deformation and becomes ring-shaped again; then the second fixing ring 7 is fastened to the first fixing ring 4 by the fastener 8, thereby fixing the first fixing ring 4 and the second fixing ring 7 on the base 2. At this time, the inner edges of the first fixing ring 4 and the second fixing ring 7 cooperate to form a mounting hole 9 that is adapted to the size of the downlight 1. The downlight 1 can be installed on the base 2 through the mounting hole 9, so that the small-sized downlight 1 can be adapted to the large-sized opening 3, thereby improving the installation adaptation range of the downlight 1.

[0047] Example 2

[0048] Embodiment 2 of the present invention provides a downlight device, which includes a downlight 1, and also includes a first fixing ring 4, a second fixing ring 7 and a fastener 8 in the downlight installation structure adapted to the large opening as described in Embodiment 1, and is suitable for installing the downlight 1 into an opening 3 pre-opened in the base 2 through the installation structure.

[0049] The downlight device can conveniently install the downlight 1 into the opening 3 with a larger size through the first fixing ring 4, the second fixing ring 7 and the fastener 8, thus having a wider installation adaptation range.
