Description

Technical Field

[0001] The invention belongs to the technical field of embedded lamp installation, and in particular relates to an installation device for an embedded lamp with adjustable size. Background Art

[0002] Downlights are a type of lighting fixture embedded in the ceiling that emits light downwards. They have both lighting and decorative functions and are popular among the public because they are easy to install, do not take up space, are generous, durable and cheap. When installing existing downlights, holes must be drilled in the ceiling in advance according to the size of the downlight. When the size of the hole does not correspond to the downlight model, the downlight cannot be installed normally and the downlight needs to be replaced or the size of the hole needs to be adjusted, resulting in high installation costs.

[0003] National Patent Publication No. CN114484341A provides an installation device for an embedded lamp with adjustable size, the installation device comprising: a guide assembly; a sliding assembly slidably connected to the guide assembly, the sliding assembly being provided with a side spring for fixing the embedded lamp to the ceiling; a limit assembly and the guide assembly are both fixedly mounted on the back cover of the embedded lamp, the limit assembly being used to limit the position of the sliding assembly on the guide assembly so that the distance between the two side springs matches the size of the mounting hole on the ceiling; the installation device adjusts the relative position of the two side springs on the sliding assembly by causing the sliding assembly to slide along the guide assembly, and causes the distance between the two side springs to match the sizes of different mounting holes on the ceiling.

[0004] The above patent completes the adjustment of the installation size through the guide component, the sliding component and the limit component. This process is mainly achieved by setting the size on the back cover and adding a limit structure. When in use, only one sliding component can be adjusted first, and then the other sliding component can be adjusted. Synchronous movement cannot be achieved, and the operation is very cumbersome. Moreover, the size set on the back cover is too fixed to achieve adjustment of any size within the range. That is to say, a size of 10.5 cm, for example, cannot be achieved on this device. At the same time, creation is to simplify complex things. This device is provided with a locking block, an adjustment part and a spring in the sliding component. The structure is complex, the production is troublesome, the mold opening cost is high, and it is not practical.

[0005] The above problems are in urgent need of improvement and need to be resolved. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, a mounting device for an embedded lamp with adjustable size is now proposed.

[0007] The technical solution adopted by the present invention is: providing an installation device for an embedded lamp with adjustable size, including a back cover with a dustproof function, an adjustment bracket installed on the back cover, an adjustment device installed on the adjustment bracket, and a pair of sliding components installed on the adjustment device and capable of synchronously moving inward or outward.

[0008] Preferably, the rear cover includes a sealing ring, a cover body for mounting the sealing ring, and a bracket hole provided on the cover body.

[0009] Preferably, the adjustment bracket includes a pair of bracket frames, a rotation hole arranged between two mirror-image combination bracket frames, and sliding holes arranged on both sides of the rotation hole.

[0010] Preferably, the support frame includes a frame body, two semicircular holes provided at two ends of the frame body, slide grooves provided at two sides of the two semicircular holes, and turntable holes connected to the slide grooves at both sides.

[0011] Preferably, the two bracket frames are mirror-imaged by the upper semicircular hole to the lower semicircular hole, the upper slide groove to the lower slide groove, and the upper turntable hole to the lower turntable hole; the upper semicircular hole and the lower semicircular hole are combined to form a turntable hole, and the upper slide groove and the lower slide groove are combined to form a slide hole.

[0012] Preferably, the adjusting device comprises a turntable, screw rods mirror-mounted on both sides of the turntable, and a rotating shaft arranged on the screw rods.

[0013] Preferably, the sliding assembly includes a spring lock, a base for mounting the spring lock, a threaded hole provided on the base for connecting the screw, and sliding blocks arranged on both sides of the threaded hole.

[0014] The beneficial effects of the present invention are:

[0015] The pair of sliding components described in the present invention can move inward or outward synchronously on the adjustment device. During the movement, there is no need to manually wave the sliding components. Only the turntable on the adjustment device needs to be rotated. When the turntable rotates counterclockwise or clockwise, the sliding components on the two screws can be driven to move closer to or away from the turntable. The distance between the two spring locks is adjusted to match the sizes of different mounting holes on the ceiling. The device is not only simple in structure, but also solves the problem that the installation device with adjustable size for embedded lamps provided in Publication No. CN114484341A cannot adjust the two sliding components at the same time. The adjustment accuracy is higher and the movement can be performed at the millimeter level. At the same time, the structure is simple, no limit component is required, the production is simple, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below in conjunction with specific drawings.

[0024] Specifically, a mounting device for an adjustable size of an embedded lamp is provided, including a dustproof back cover 10, an adjustment bracket 20 mounted on the back cover 10, an adjustment device 30 mounted on the adjustment bracket 20, and a pair of sliding components 40 mounted on the adjustment device 30 and capable of synchronously moving inward or outward.

[0025] like Figure 1 As shown, after the ceiling hole is opened, the pair of sliding components 40 mirror-mounted on the adjusting device 30 can be adjusted by the adjusting device 30, and the adjusting device 30 can make the pair of sliding components 40 move inward or outward synchronously, according to the size of the hole diameter. If the hole diameter is larger than the distance between the pair of sliding components 40, the adjusting device 30 is adjusted to make the pair of sliding components 40 move outward synchronously, so that the distance between the pair of sliding components 40 is equal to the hole diameter, and the pair of sliding components 40 can be embedded in the hole to complete the installation; conversely, if the hole diameter is smaller than the distance between the pair of sliding components 40, the adjusting device 30 is adjusted to make the pair of sliding components 40 move inward synchronously, so that the distance between the pair of sliding components 40 is equal to the hole diameter, and the pair of sliding components 40 can be embedded in the hole to complete the installation.

[0026] Furthermore, the back cover 10 includes a sealing ring 11 , a cover body 12 for mounting the sealing ring 11 , and a bracket hole 13 provided on the cover body 12 .

[0027] like Figure 1 and Figure 2As shown, the outer diameter of the sealing ring 11 is the same as that of the cover body 12, and is installed on the upper surface of the cover body 12. When the sliding assembly 40 is embedded in the opening, the cover body 12 is pulled up. At this time, the sealing ring 11 and the ceiling are squeezed and in close contact to achieve a sealing effect, preventing external dust from entering the lamp. At the same time, it also has a certain protective effect on the ceiling to prevent the ceiling from being pressed out by the cover body 12.

[0028] Furthermore, the adjustment bracket 20 includes a pair of bracket frames 21 , a rotation hole 22 disposed between two mirror-image combination bracket frames 21 , and sliding holes 23 disposed on both sides of the rotation hole 22 .

[0029] Furthermore, the support frame 21 includes a frame body 211 , two semicircular holes 212 provided at two ends of the frame body 211 , slide grooves 213 provided at two sides of the two semicircular holes 212 , and turntable holes 214 connected to the slide grooves 213 at both sides.

[0030] Furthermore, the two bracket frames 21 are mirror-imaged by the upper semicircular hole 212 to the lower semicircular hole 212, the upper slide groove 213 to the lower slide groove 213, and the upper turntable hole 214 to the lower turntable hole 214; the upper semicircular hole 212 and the lower semicircular hole 212 are combined to form the turntable hole 22, and the upper slide groove 213 and the lower slide groove 213 are combined to form the slide hole 23.

[0031] Furthermore, the adjusting device 30 includes a turntable 31 , screw rods 32 mirror-mounted on both sides of the turntable 31 , and a rotating shaft 33 disposed on the screw rods 32 .

[0032] Furthermore, the sliding assembly 40 includes a spring lock 41 , a base 42 for mounting the spring lock 41 , a threaded hole 43 provided on the base 42 for connecting with the screw rod 32 , and sliders 44 provided on both sides of the threaded hole 43 .

[0033] like Figure 7 As shown, the two sliders 44 are respectively installed on both sides of the base 42.

[0034] like Figures 1 to 7 As shown, the present invention is simple to manufacture. The adjustment bracket 20 includes a pair of bracket frames 21. According to the manufacturing process, the adjustment device 30 and the sliding assembly 40 can be installed through the pair of bracket frames 21, and then embedded in the bracket hole 13 of the back cover 10. This installation method requires a structure for fixing the pair of bracket frames 21, which is slightly complicated.

[0035] Therefore, one of the bracket frames 21 of the pair of bracket frames 21 can be fixed in the bracket hole 13 of the back cover 10 in an integrally formed manner, and then the sliding component 40 can be screwed onto the screw 32 of the adjusting device 30 through the threaded hole 43, and the sliding components 40 on the left and right sides of the adjusting device 30 are in opposite directions, that is, the spring locks 41 on the sliding components 40 are both facing the cover body 12, and the distance from the inner wall of the base 42 in the two sliding components 40 to the center of the adjusting device 30 is equal.

[0036] After completing the above process, the rotating shafts 33 on the two screws 32 in the adjusting device 30 are respectively embedded in the semicircular holes 212 on the bracket frame 21 fixed in the bracket hole 13. At this time, the turntable 31 in the adjusting device 30 is just embedded in the turntable hole 214 on the bracket frame 21, and the sliders 44 on both sides of the two bases 42 are just embedded in the two slide grooves 213 of the bracket frame 21.

[0037] Finally, by mirroring, another bracket frame 21 is installed up and down in the manner of semicircular hole 212 against semicircular hole 212, turntable hole 214 against turntable hole 214, and slide groove 213 against slide groove 213. After installation, it is fixed with self-tapping screws or the like.

[0038] At this time, the rotating shaft 33 can rotate in the rotating hole 22 formed by splicing the semicircular holes 212 and the semicircular holes 212, and the base 42 installed on the screw rod 32 in a threaded manner, because the slider 44 is stuck in the sliding hole 23 formed by splicing the sliding groove 213 and the sliding groove 213, so that when the rotating shaft 33 rotates, the base 42 is forced to move forward or backward.

[0039] The screw rods 32 on both sides of the turntable 31 are mirror-imaged, so that the bases 42 on the two screw rods 32 can be moved inward or outward synchronously. The distance between the two sliding components 40 can be adjusted by simply rotating the turntable 31. When the turntable 31 does not rotate, the two sliding components 40 cannot move. Therefore, there is no need to set any limit components, the structure is simple, and the manufacturing cost is low.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above and the description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
