Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and in particular to a height-adjustable embedded light. Background Technology

[0002] Embedded lights, as recessed lighting devices, are widely used in ceiling lighting scenarios in building decoration. They are highly concealed, have a high space utilization rate, and can be well matched with the decoration style.

[0003] Pre-embedded lights typically consist of a pre-embedded frame and a light fixture inserted into the pre-embedded frame. To meet people's needs for adjustable light, pre-embedded lights with adjustable height have appeared on the market, but adjusting the height of this type of pre-embedded light is usually quite troublesome.

[0004] For example, Chinese patent CN221975151U discloses a frameless snap-fit ​​profile recessed light fixture, including a light body and a recessed frame. The recessed frame is hollow and fits onto the light body. Mounting brackets are provided on opposite sides of the recessed frame for installation inside the ceiling. The mounting brackets have vertically oriented strip-shaped adjustment holes, and the recessed frame has threaded grooves corresponding to these holes. Adjusting bolts for threaded engagement with the threaded grooves pass through the strip-shaped adjustment holes. When installing the recessed light, workers adjust the height of the recessed frame relative to the mounting brackets by adjusting the vertical position of the bolts in the strip-shaped adjustment holes. If the light body needs maintenance or replacement, the bolts must be removed, the repaired light body reinstalled, and reconnected to the recessed frame using bolts, making the process cumbersome.

[0005] In view of this, the present invention proposes a height-adjustable embedded light to address the shortcomings of the prior art. Utility Model Content

[0006] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a height-adjustable embedded light, which can not only adjust the height position of the light fixture, but also makes the installation and disassembly of the light fixture simple and easy to maintain.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable height embedded light includes a hollow embedded frame for fixing to the ceiling and a light fixture inserted into the embedded frame. The light fixture has guide grooves extending downwards from its upper end on both its left and right sides, and multi-level positioning strips located within the guide grooves. Each multi-level positioning strip has multiple guide ramps on its front or rear side, with locking recesses between adjacent guide ramps. The multi-level positioning strips divide the guide grooves into a locking channel and a reset channel, one in front and one behind. The locking channel is located on one side of the guide ramp; the reset channel is located on the side of the multi-level positioning strip without guide ramps. Elastic components are installed on both the left and right inner sides of the embedded frame. These elastic components have locking pins that can slide down the guide ramps to the locking recesses. The locking pins locking into different locking recesses allow for height adjustment of the light fixture. A catapult assembly is also provided between the lamp and the embedded frame. When the lamp is in the highest position, the locking pin is at the lowest point of the multi-level positioning bar. The locking pin can be switched to the reset channel. At the same time, the catapult assembly is used to catapult the lamp downward, so that the locking pin is disengaged from the reset channel upward.

[0009] As a preferred technical solution, the ejection assembly includes a reset spring and a connecting assembly installed in the pre-embedded frame. The reset spring is connected to the lamp through the connecting assembly. The connecting assembly is used to compress the reset spring when the lamp is pressed upward. The restoring force of the compressed reset spring can eject the lamp downward and cause the locking pin to disengage upward from the reset channel.

[0010] As a preferred technical solution, the connecting assembly includes a housing fixedly connected to the inner wall of the pre-embedded frame and a spring mounting component. The housing has a spring groove for accommodating a reset spring. The spring mounting component includes a mounting body, a connecting protrusion integrally formed with the mounting body, and a transmission protrusion. The mounting body is located inside the housing, the connecting protrusion is located inside the spring groove, and the connecting protrusion abuts against the bottom of the reset spring. The transmission protrusion extends out of the housing towards the lamp fixture, and the outer wall of the lamp fixture has a transmission step, on which the transmission protrusion rests.

[0011] As a preferred technical solution, the elastic component includes, from top to bottom, a mounting part for fixed connection with the pre-embedded frame, a zigzag telescopic part, and a locking pin.

[0012] As a preferred technical solution, the lamp is provided with a pair of multi-level positioning strips on both the left and right sides. The multi-level positioning strips in the same pair are symmetrical about the vertical direction, and each multi-level positioning strip is provided with a guide groove.

[0013] As a preferred technical solution, the mounting part is provided with a zigzag telescopic part at both the front and rear ends, and the elastic component is provided with two locking pins, which are respectively located below the two zigzag telescopic parts.

[0014] As a preferred technical solution, the elastic component is formed by bending a metal strip, and there is a snap-fit ​​cutout between the mounting part and the zigzag telescopic part. An mounting plate is provided between the elastic component and the multi-level positioning strip. The mounting plate is provided with a connecting block, which is located within the snap-fit ​​cutout and is used to support the elastic component. The mounting plate is fixedly connected to the pre-embedded frame by screws, and the locking pin is located below the mounting plate.

[0015] As a preferred technical solution, the pre-embedded frame is provided with fixing protrusions on both the left and right inner sides for locking and engaging the hollowed-out parts.

[0016] As a preferred technical solution, the embedded frame includes two short frame plates and two long frame plates extending in the left and right directions. The two short frame plates are respectively spliced ​​to the left and right ends of the long frame plates to form the embedded frame. The long frame plates are provided with flanges, and the flanges are provided with countersunk holes.

[0017] As a preferred technical solution, the lamp is provided with transmission steps on both the front and rear sides, and the pre-embedded frame is provided with reset springs and connecting components on both the front and rear inner sides.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model uses an elastic component and multi-level positioning strips to form a press-type height adjustment structure. After the pre-embedded light is installed, simply press the light fixture upwards, and the locking pin will slide along the guide slope into different locking recesses, easily achieving height switching without complicated disassembly steps, making it convenient for users. This utility model can change the light illumination range by precisely adjusting the height of the light fixture, meeting the basic lighting needs of different spaces.

[0020] 2. When disassembling the lamp, the user simply presses the lamp upwards until it reaches its highest position. At this point, the locking pin is at the lowest point of the multi-level positioning bar, allowing it to switch to the reset channel. The ejector assembly then ejects the lamp downwards, causing the locking pin to disengage from the reset channel, allowing the lamp to be removed. When installing the lamp, simply insert it from the bottom of the pre-embedded frame. The locking pin engages in the locking channel, and the lamp slides down the guide ramp to the locking recess, completing the installation. The lamp can be installed and removed without disassembling the pre-embedded frame or elastic components, making the operation simple. Furthermore, during lamp removal, the ejector assembly ejects the lamp downwards, causing the locking pin to quickly disengage from the reset channel, eliminating the need for manual pulling of the lamp and improving the ease of disassembly and user experience.

[0021] 3. The elastic component is formed by bending a metal strip, possessing excellent elasticity and mechanical strength. Compared to materials such as plastic, metal elastic components are less prone to breakage. They can withstand repeated deformation from long-term pressure adjustment. Attached Figure Description

[0031] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0032] Reference Figures 1-8 This utility model provides an embodiment of a height-adjustable pre-embedded light.

[0033] A height-adjustable embedded light, such as Figure 1 As shown, it includes a hollow pre-embedded frame 1 for fixing to the ceiling and a light fixture 2 inserted into the pre-embedded frame 1.

[0034] The lamp 2 has guide grooves 22 extending downward from the top of the lamp 2 on both its left and right sides, and multi-level positioning strips 21 located within the guide grooves 22. Multiple guide ramps 211 are provided on the front or rear side of the multi-level positioning strips 21, with locking recesses 212 between adjacent guide ramps 211. The multi-level positioning strips 21 divide the guide grooves 22 into a locking channel 221 and a reset channel 222, with the locking channel 221 located on one side of the guide ramps 211; the reset channel 222 is located on the side of the multi-level positioning strips 21 without guide ramps 211.

[0035] The pre-embedded frame 1 has elastic components 3 installed on both its left and right inner sides. Each elastic component 3 has locking pins 33. The locking pins 33 can slide down the guide slope 211 to the locking recess 212, such as... Figure 7 As shown, the locking pin 33 can be locked in different locking recesses 212 to achieve height adjustment of the lamp 2. Adjusting the height of the lamp 2 can change the light illumination range and meet the basic lighting needs of different spaces.

[0036] A ejector assembly is also provided between the lamp 2 and the pre-embedded frame 1. When the lamp 2 needs to be removed, simply press the lamp 2 upward until it is in the highest position. At this time, the locking pin 33 is at the lowest point of the multi-level positioning bar 21. The locking pin 33 can switch to the reset channel 222. Then the ejector assembly ejects the lamp 2 downward, so that the locking pin 33 disengages from the reset channel 222 and the lamp 2 can be removed. The operation is convenient.

[0037] like Figure 3 As shown, the ejection assembly includes a reset spring 41 installed in the pre-embedded frame 1 and a connecting assembly. The reset spring 41 is connected to the lamp 2 through the connecting assembly. The connecting assembly is used to compress the reset spring 41 when the lamp 2 is pressed upward. The restoring force of the compressed reset spring 41 can eject the lamp 2 downward and cause the locking pin 33 to disengage upward from the reset channel 222.

[0038] like Figure 4 As shown, the connecting assembly includes a housing 42 fixedly connected to the inner wall of the pre-embedded frame 1 and a spring mounting component 43. The housing 42 has a spring groove 421 for accommodating the reset spring 41. The spring mounting component 43 includes a mounting body 433, a connecting protrusion 431 integrally formed with the mounting body 433, and a transmission protrusion 432. The mounting body 433 is located inside the housing 42, the connecting protrusion 431 is located inside the spring groove 421, and the connecting protrusion 431 abuts against the bottom of the reset spring 41. The transmission protrusion 432 extends out of the housing 42 towards the lamp fixture 2. The outer wall of the lamp fixture 2 has a transmission step 23, and the transmission protrusion 432 rests on the transmission step 23.

[0039] The lamp 2 has transmission steps 23 on both its front and rear sides, and the embedded frame 1 has return springs 41 and connecting components on both its front and rear inner sides. Multi-level positioning strips 21 are set on the left and right sides of the lamp 2, and transmission steps 23 are set on the front and rear sides of the lamp 2, making the structural layout of the lamp 2 reasonable.

[0040] The elastic component 3 includes, from top to bottom, a mounting part 31 for fixed connection with the pre-embedded frame 1, a zigzag telescopic part 32, and a locking pin 33. The zigzag telescopic part 32 can extend and retract slightly, allowing the locking pin 33 to move relative to the guide slope 211, the locking recess 212, and the reset channel 222.

[0041] The installation process and working principle of the lamp 2 of this utility model:

[0042] First, the pre-embedded frame 1 is fixedly connected to the ceiling. Then, the light fixture 2 is inserted from the bottom of the pre-embedded frame 1, the locking pin 33 is inserted into the locking channel 221, and slides down the guide slope to the locking recess to realize the installation of the light fixture 2.

[0043] The process and working principle of adjusting the height of the lamp 2 of this utility model:

[0044] After the lamp 2 is installed in the pre-embedded frame 1, the user presses the lamp 2 upwards. The lamp 2 drives the transmission step 23 on the outer wall to move upwards. The transmission step 23 is linked to the protrusion 431, causing the return spring 41 to compress and accumulate restoring force. At the same time, during the upward movement of the lamp 2, the multi-stage positioning strip 21 moves upwards together with the lamp 2. The guide slope 211 on the multi-stage positioning strip 21 contacts the locking pin 33 of the elastic component 3 on the inner side of the pre-embedded frame 1. Due to the inclined guiding effect of the guide slope 211, the locking pin 33 moves downwards relative to the guide slope 211 to the next locking recess 212, stopping the upward pressing of the lamp 2. The locking pin 33 and the locking recess 212 cooperate, locking the lamp 2 at this height. During this upward pressing of the lamp 2, the zigzag telescopic part 32 deforms. By selecting locking recesses 212 of different heights, the height of the lamp 2 can be adjusted step by step. This utility model uses the elastic component 3 and the multi-level positioning strip 21 to form a press-type height adjustment structure. After the pre-embedded light is installed, the light fixture 2 only needs to be pressed upwards, and the locking pin 33 can slide into different locking recesses 212 along the guide slope 211 to easily achieve height switching without complicated disassembly steps, which is convenient for users to operate.

[0045] The disassembly process and working principle of the lamp 2 of this utility model:

[0046] The user presses the lamp 2 upwards until it reaches its highest position, at which point the locking pin 33 is at the lowest point of the multi-stage positioning bar 21. When the locking pin 33 is at the lowest point of the multi-stage positioning bar 21, it can switch from the locking channel 221 to the reset channel 222. With the locking pin 33 switched to the reset channel 222, the user can stop pressing on the lamp 2, and the compressed reset spring 41 will return to its original length. Because the connecting protrusion 431 of the spring mounting member 43 abuts against the bottom of the reset spring 41, the reset spring 41 will drive the spring mounting member 43 to move downwards as a whole. Since the transmission protrusion 432 of the spring mounting member 43 rests on the transmission step 23 of the lamp 2, the lamp 2 and the spring mounting member 43 move downwards together. Simultaneously, the multi-stage positioning bar 21 and the guide groove 22 move downwards along with the lamp 2. For the pre-embedded frame 1, the position of the locking pin 33 of the elastic component 3 remains unchanged; however, for the multi-level positioning bar 21, the locking pin 33 moves upward, moving upward along the reset channel 222 until it disengages from the reset channel 222, that is, the lamp 2 disengages from the pre-embedded frame 1. The installation and removal of the lamp 2 is simple, making it convenient for users to inspect, replace, and install the lamp 2.

[0047] The lamp 2 has a pair of multi-level positioning strips 21 on both the left and right sides. The multi-level positioning strips 21 in the same pair are symmetrical about the vertical axis, and each multi-level positioning strip 21 is provided with a corresponding guide groove 22. Figure 8 As shown ( Figure 8 The dashed lines are used to sequentially distinguish the mounting part, the zigzag telescopic part, and the locking pins of the elastic component. Each end of the mounting part 31 has a zigzag telescopic part 32. The elastic component 3 has two locking pins 33, located below the two zigzag telescopic parts 32. The locking pins 33 face the guide groove 22 and are cylindrical.

[0048] The lamp 2 is more stable when it moves up and down by four evenly distributed locking pins 33 and four multi-level positioning bars 21 on the left and right sides.

[0049] The elastic component 3 is a component formed by bending a metal strip. It has good elasticity and mechanical strength. Compared with materials such as plastic, the metal elastic component 3 is not easy to break and can withstand repeated deformation under long-term pressure adjustment.

[0050] A snap-fit ​​opening 34 exists between the mounting part 31 and the zigzag telescopic part 32. A mounting plate 4 is provided between the elastic component 3 and the multi-level positioning strip 21. The mounting plate 4 has a connecting block 44, which is located within the snap-fit ​​opening 34 and is used to support the elastic component 3. The mounting plate 4 is fixedly connected to the embedded frame 1 by screws, so that the elastic component 3 is installed in the embedded frame 1. The locking pin 33 is located below the mounting plate 4 and can smoothly cooperate with the multi-level positioning strip 21.

[0051] like Figure 2 As shown, the two inner sides of the pre-embedded frame 1 are provided with fixing protrusions 11, which can be snapped into the slotted cutout 34 to reinforce the connection between the pre-embedded frame 1 and the elastic component 3.

[0052] The embedded frame 1 includes two short frame plates 13 and two long frame plates 12 extending in the left-right direction. The two short frame plates 13 are respectively spliced ​​to the left and right ends of the long frame plates 12 to form the embedded frame 1. Specifically, the inner wall of the long frame plate 12 is provided with an elongated hole 121 that runs through the entire long frame plate 12 in the left-right direction, and the short frame plates 13 are connected to the elongated hole 121 by screws. The long frame plate 12 is provided with a flange 14, and the flange 14 is provided with a countersunk hole 141. The countersunk hole 141 can be connected to the ceiling by screws, so that the embedded frame 1 is fixedly connected to the ceiling.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
