Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more particularly to a ceiling light. Background Technology

[0002] Ceiling lights are a type of lighting fixture. They are called ceiling lights because the top of the fixture is relatively flat and the bottom is completely attached to the ceiling when installed.

[0003] In related technologies, a ceiling light includes a base, a mounting bracket, and two mounting components arranged opposite each other. Specifically, each mounting component includes a pressing plate, an overlapping block, and a spring. The pressing plate is slidably connected to the mounting bracket, with one end located outside the mounting bracket. The overlapping block is located on the mounting plate, and the spring is located between the pressing plate and the mounting bracket to drive the overlapping block out of the mounting bracket. When installing the ceiling light, the base is first fixed to the roof. Then, the two pressing plates are pressed, causing them to slide towards each other, allowing the overlapping block to extend into the mounting bracket. At this point, the upper end of the mounting bracket is inserted into the base, and the pressing of the pressing plates is released, allowing the overlapping block to extend out of the mounting bracket and overlap the inner edge of the lower end of the base, thus completing the installation of the ceiling light.

[0004] However, in practical applications, for some larger ceiling lights, relying solely on two connecting blocks to the chassis results in poor installation stability, thus requiring improvement.

[0005] Practical content

[0006] To ensure the stability of large-sized ceiling lights during installation, this application provides a ceiling light.

[0007] The ceiling light provided in this application adopts the following technical solution:

[0008] A ceiling light includes a base and a mounting bracket. The upper end of the mounting bracket is inserted into the base. The light also includes two opposing mounting components. Each mounting component includes a pressing member, two overlapping blocks, and a first elastic member. The pressing member is slidably connected to the mounting bracket, with its sliding direction aligned with the center of the mounting bracket. One end of the pressing member, away from the center of the mounting bracket, protrudes from the outer periphery of the mounting bracket. The two overlapping blocks are symmetrically arranged on both sides of the pressing member and connected to it. Both overlapping blocks are slidably connected to the mounting bracket, with their sliding direction aligned with the center of the mounting bracket. The first elastic member is located between the pressing member and the mounting bracket to drive the pressing member away from the center of the mounting bracket, thereby causing the pressing member to pull the two overlapping blocks out of the mounting bracket.

[0009] By adopting the above technical solution, in practical applications, the chassis is fixedly connected to the roof. By pressing the pressing parts on both sides, the pressing parts slide towards the center of the hanger. The pressing parts drive the corresponding two overlapping blocks to slide into the hanger, and at this time, the first elastic element is compressed. Then, the hanger is inserted into the base and the pressing parts are released. The first elastic element resets and drives the pressing parts to slide away from the center of the hanger, thereby driving the corresponding two overlapping blocks to extend out of the hanger and overlap with the chassis, so as to realize the installation of the ceiling light. Among them, by having four overlapping blocks overlap with the chassis, it can be used for ceiling lights of both large and small sizes, and can ensure the stability of the installation of large-size ceiling lights as much as possible.

[0010] Preferably, the installation assembly further includes two connecting seats, which are slidably connected to the hanger and the two overlapping blocks are respectively disposed on the two connecting seats, and each of the two connecting seats is provided with a connecting groove; the pressing member includes a connecting plate and a pressing plate, the connecting plate is disposed at one end of the pressing plate near the center of the hanger, and the two sides of the connecting plate away from the pressing plate are respectively engaged with the two connecting grooves.

[0011] By adopting the above technical solution, the connecting seat provides an installation base for the overlapping block, so as to realize the sliding connection of the overlapping block to the hanger, and the connecting plate is snapped into the connecting groove of the two connecting seats, so that the pressing part drives the two connecting seats to slide. The structure is simple and easy to install.

[0012] Preferably, the pressing component further includes an elastic mounting strip, which is positioned on the hanger and has both ends located on both sides of the connecting plate away from the pressing plate.

[0013] By adopting the above technical solution, and by setting an installation strip, the installation strip is positioned and installed on the hanger to achieve the positioning and installation of the connecting plate. Moreover, the installation strip is elastic, which further realizes the reset of the pressing part position, thereby improving the stability of the overlapping block overlapping the chassis.

[0014] Preferably, the connecting plate has a snap-fit ​​block at one end near the pressing plate, and the pressing plate has a snap-fit ​​groove at one end near the connecting plate, and the snap-fit ​​block snaps into the snap-fit ​​groove.

[0015] By adopting the above technical solution, and by setting the snap-fit ​​block and snap-fit ​​groove, the connection plate and the pressing plate are fixed together, so that the connection plate and the pressing plate slide synchronously. The structure is simple and easy to install, so as to facilitate the overall installation of the pressing component.

[0016] Preferably, the hanger is provided with a mounting block, the end of the connecting plate away from the pressing plate is provided with a groove, the connecting plate is provided with a connecting post in the groove, one end of the first elastic member elastically abuts against the mounting block, and the other end is sleeved on the connecting post and elastically abuts against the connecting plate.

[0017] By adopting the above technical solution, by setting an installation block, the two ends of the first elastic element are elastically connected to the grooves of the installation block and the connecting plate respectively, so as to realize the installation of the first elastic element. One end of the first elastic element is sleeved on the connecting post, which can limit the excessive bending and deformation of the first elastic element, thereby improving the service life of the first elastic element. Furthermore, with the cooperation of the connecting post and the groove, the installation stability of the first elastic element is improved.

[0018] Preferably, the end of the connecting post furthest from the connecting plate is chamfered.

[0019] By adopting the above technical solution, the end of the connecting post away from the connecting plate is beveled to facilitate the fitting of the first elastic element onto the connecting post.

[0020] Preferably, the hanger is further provided with four sliding seats, the four connecting seats are respectively slidably connected to the four sliding seats, and the hanger is provided with clearance grooves at each of the four sliding seats for the overlapping block to pass through.

[0021] By adopting the above technical solution, four sliding seats are set to limit the sliding of the four connecting seats, thereby improving the stability of the sliding of the connecting seats. The overlapping block extends out of or into the hanger from the relief groove. At the same time, the sliding seats can strengthen the structural strength of the hanger located at the relief groove, so as to ensure the overall strength of the hanger.

[0022] Preferably, the four sliding seats are evenly spaced along the circumference of the hanger.

[0023] By adopting the above technical solution, and by evenly spacing four sliding seats along the circumference of the hanger, the four overlapping blocks are evenly overlapped on the chassis, so that the ceiling light is subjected to uniform force and the stability of the ceiling light installation is further improved.

[0024] Preferably, the mounting assembly further includes two second elastic members, one end of each second elastic member elastically abutting against each of the sliding seats, and the other end elastically abutting against each of the connecting seats, so as to drive each of the connecting seats away from the center of the hanger.

[0025] By adopting the above technical solution and setting a second elastic element, the second elastic element can drive the connecting seat away from the center of the hanger, so as to drive the overlapping block to slide, and further enable the overlapping block to extend out of the hanger through the relief groove and overlap with the chassis, thereby improving the stability of the ceiling light installation.

[0026] Preferably, the chassis is provided with a guide boss, the guide boss is tapered, and the diameter of the upper end of the guide boss is larger than the diameter of the lower end.

[0027] By adopting the above technical solution, and by setting a guide wire boss, it is possible to insert the hanger into the chassis.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By using four overlapping blocks to connect to the chassis, it can be used for ceiling lights of both large and small sizes, and can ensure the stability of the installation of large ceiling lights as much as possible;

The installation strip is elastic, which further realizes the reset of the pressing part position, thereby improving the stability of the overlapping block overlapping the chassis.

[0031] 3. By setting four sliding seats for the four connecting seats to limit sliding, the stability of the connecting seats sliding is improved, and the overlapping block extends from or into the hanger from the relief groove.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0041] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0043] This application discloses a ceiling light.

[0044] Reference Figure 1 and Figure 2 The ceiling light includes a base 1, a mounting bracket 2, and two mounting components 3. The base 1 is a hollow disc with an opening at the bottom, and the bottom of the base 1 protrudes inward along its circumference to form an overlapping ring 11. The mounting bracket 2 is also a hollow disc with an opening at the bottom, and the upper end of the mounting bracket 2 is inserted into the base 1.

[0045] Reference Figure 3 and Figure 4Two mounting components 3 are arranged opposite each other and symmetrically about the center of the hanger 2. Specifically, the mounting component 3 includes a pressing member 31, two overlapping blocks 32, and a first elastic member 33. The pressing member 31 is slidably connected to the hanger 2, and its sliding direction is on the same straight line as the center of the hanger 2. The end of the pressing member 31 away from the center of the hanger 2 protrudes from the outer periphery of the hanger 2 for the installer to press and move it. The two overlapping blocks 32 are symmetrically arranged on both sides of the pressing member 31 and are fixedly connected to it. The two overlapping blocks 32 are slidably connected to the hanger 2, and their sliding direction is also on the same straight line as the center of the hanger 2.

[0046] Reference Figure 4 and Figure 5 In this embodiment, the first elastic element 33 is a spring. In other embodiments, the first elastic element 33 can also be an elastic sleeve. The first elastic element 33 is disposed between the pressing element 31 and the hanger 2 to drive the pressing element 31 to slide toward the end away from the center of the hanger 2, so as to drive the two overlapping blocks 32 to extend out of the hanger 2, so that the two overlapping blocks 32 overlap on the upper side of the overlapping ring 11.

[0047] During actual installation, the upper end of the chassis 1 is fixed to the roof with bolts. The installer presses down on one end of the two pressing parts 31 protruding from the hanger 2, so that the two pressing parts 31 slide towards the end closer to the center of the hanger 2. During the sliding process, each pressing part 31 drives the corresponding two overlapping blocks 32 to extend into the hanger 2, and the first elastic element 33 is compressed. At this time, the upper end of the hanger 2 can be inserted into the chassis 1, so that the upper end of the hanger 2 is inserted into the chassis 1. Then, the pressing of the two pressing parts 31 is released, and each first elastic element 33 is reset, so that the two pressing parts 31 slide towards the end away from the center of the hanger 2, thereby driving the corresponding two overlapping blocks 32 to extend out of the hanger 2. Each overlapping block 32 overlaps with the overlapping ring 11 to realize the installation of the ceiling light. It should be noted that at this time, the four overlapping blocks 32 overlap with the overlapping ring 11, which can ensure the stability of the installation of large-size ceiling lights, and at the same time improve the stability of the installation of small-size ceiling lights, thus making it more versatile.

[0048] Reference Figure 2 and Figure 5 In some embodiments, a guide boss 12 protrudes from the chassis 1. The guide boss 12 is narrowed to form a frustum shape, and the diameter of the lower end of the guide boss 12 is smaller than the diameter of the upper end of the guide boss 12. When the hanger 2 is inserted into the guide boss 12, under the guidance of the guide boss 12, it is not necessary to accurately align the hanger 2 with the chassis 1, thereby facilitating the insertion of the hanger 2 into the chassis 1.

[0049] Reference Figure 3 and Figure 4In some embodiments, the pressing member 31 includes a connecting plate 311 and a pressing plate 312. The connecting plate 311 is fixedly connected to the end of the pressing plate 312 near the center of the hanger 2. The hanger 2 has two protruding slide rails 21 corresponding to the two pressing members 31, respectively. The two slide rails 21 are arranged opposite each other and are both on the same straight line as the center of the hanger 2. The connecting plate 311 and the pressing plate 312 are slidably connected to the slide rails 21, thereby enabling the pressing member 31 to be slidably connected to the hanger 2. The end of the pressing plate 312 away from the connecting plate 311 protrudes from the hanger 2 and has an arc-shaped pressing head 312a to facilitate pressing the pressing plate 312.

[0050] Meanwhile, the mounting assembly 3 also includes two connecting seats 34, and two overlapping blocks 32 are integrally connected to the two connecting seats 34 respectively. The two connecting seats 34 are slidably connected to the hanger 2 to achieve the sliding connection of the overlapping blocks 32 to the hanger 2. The connecting seats 34 are provided with arc-shaped connecting grooves 341, which are concentric with the hanger 2 and have rounded corners 342 at their edges. Correspondingly, the two sides of the connecting plate 311 at the end away from the pressing plate 312 extend along the circumference of the hanger 2 and are respectively engaged in the two connecting grooves 341 to achieve the connection between the pressing member 31 and the two overlapping blocks 32. The structure is simple and easy to install. It should be noted that the connecting plate 311 has a certain degree of elasticity, so that the connecting plate 311 has a certain amount of deformation to avoid interference during sliding and ensure that the connecting seats 34 can slide normally.

[0051] Reference Figure 4 and Figure 6 In some embodiments, the pressing member 31 further includes an installation strip 313. The installation strip 313 is generally arranged in a "V" shape and is elastic. The two ends of the installation strip 313 are integrally connected to the two sides of the connecting plate 311 away from the pressing plate 312, so as to improve the overall strength of the connecting plate 311. A positioning post 22 is protruding on the hanger 2. The middle position of the installation strip 313 is inserted into the positioning post 22 to realize the positioning installation of the installation strip 313, thereby realizing the positioning installation of the connecting plate 311, which makes it easier for the connecting plate 311 to be inserted into the two connecting slots 341. In particular, since the installation strip 313 is elastic, the installation strip 313 can cooperate with the first elastic member 33 to drive the pressing member 31 to further reset, so that each overlapping block 32 extends stably from the hanger 2, thereby making the overlapping block 32 stably overlap the overlapping ring 11, and thus improving the stability of the ceiling light installation.

[0052] In some embodiments, a snap-fit ​​block 311a protrudes from one end of the connecting plate 311 near the pressing plate 312. The snap-fit ​​block 311a is T-shaped. Correspondingly, a snap-fit ​​groove 312b is provided at one end of the pressing plate 312 near the connecting plate 311. The snap-fit ​​block 311a snaps into the snap-fit ​​groove 312b to achieve a detachable connection between the connecting plate 311 and the pressing plate 312, so that the connecting plate 311 and the pressing plate 312 can slide synchronously. The structure is simple and easy to install.

[0053] In some embodiments, a mounting block 23 protrudes from the hanger 2 and is connected to the positioning post 22 to ensure support strength. Simultaneously, a groove 311b is formed at the end of the connecting plate 311 away from the pressing plate 312, and a connecting post 311c protrudes from the groove 311b on the connecting plate 311. One end of the first elastic member 33 elastically abuts against the mounting block 23, and the other end is fitted onto the connecting post 311c and elastically abuts against the connecting plate 311, thus enabling the installation of the first elastic member 33. The fitting of one end of the first elastic member 33 onto the connecting post 311c limits excessive bending deformation of the first elastic member 33, thereby improving its service life. Furthermore, the cooperation between the connecting post 311c and the groove 311b enhances the stability of the first elastic member 33's installation. It should be noted that the end of the connecting post 311c away from the connecting plate 311 is chamfered to facilitate fitting the first elastic member 33 onto the connecting post 311c.

[0054] During installation, the mounting component 3 is first inserted and slidably connected to the slide rail 21 at one end. Then, the mounting strip 313 is aligned with the positioning post 22. At this point, both sides of one end of the connecting plate 311 are aligned with the two connecting slots 341. The pressing plate 312 is then pressed down to slide it, aligning the snap-fit ​​block 311a with the snap-fit ​​groove 312b. The mounting strip 313 is then inserted into the positioning post 22, allowing the connecting plate 311 to snap into the two connecting slots 341 and the snap-fit ​​block 311a to snap into the snap-fit ​​groove 312b. This enables rapid positioning and installation of the mounting component 3, improving the assembly efficiency of the ceiling light. The structure is simple and easy to manufacture. It should be noted that a first fixing plate 24 is fixedly connected to the slide rail 21 to prevent the connecting plate 311 and the pressing plate 312 from detaching from the slide rail 21.

[0055] Reference Figure 6 and Figure 7In some embodiments, the hanger 2 is arranged in a stepped shape as required, and four sliding seats 25 protrude from the steps. The four connecting seats 34 are slidably connected to the four sliding seats 25, thereby achieving a limited sliding connection of the four connecting seats 34 to the hanger 2, which improves the stability of the sliding of the overlapping blocks 32. Limiting grooves 251 are opened on both sides of the sliding seats 25 to limit the sliding position of the connecting plate 311 and avoid excessive elastic deformation and damage due to excessive sliding. At the same time, four relief grooves 26 are opened at the steps of the hanger 2 corresponding to the four sliding seats 25, so that the four overlapping blocks 32 can extend or extend into the hanger 2. Since the structural strength of the steps of the hanger 2 is low and the relief grooves 26 are opened, the yield rate is low in injection molding. The sliding seats 25 can strengthen the structural strength of the hanger 2 at the relief grooves 26 to ensure the overall strength of the hanger 2 and improve the quality of production.

[0056] In some embodiments, four sliding seats 25 are evenly spaced along the circumference of the hanger 2, so that the four overlapping blocks 32 are evenly overlapped on the base plate 1, so that the ceiling light is subjected to uniform force and further improves the stability of the ceiling light installation.

[0057] In some embodiments, the mounting assembly 3 further includes two second elastic members 35, each corresponding to one of the two connecting seats 34. Each second elastic member 35 is also a spring; one end of each second elastic member 35 elastically abuts against the connecting seat 34, and the other end elastically abuts against the mounting groove 252 of the sliding seat 25. This drives the connecting seat 34 to slide away from the center of the hanger 2, further allowing the overlapping block 32 to extend out of the hanger 2 through the relief groove 26 and overlap with the chassis 1. This improves the stability of the ceiling light installation and requires increased pressure on the pressing plate 312 to allow it to slide, minimizing the risk of misoperation of the pressing plate 312. Furthermore, the sliding seat 25 is fixedly connected to the second fixing plate 27 to prevent the connecting seat 34, the second elastic members 35 from disengaging from the sliding seat 25.

[0058] The implementation principle of this embodiment is as follows: During the actual installation process, the upper end of the chassis 1 is fixedly connected to the roof by bolts. The installer presses two pressing parts 31 protruding from one end of the hanger 2, so that the two pressing parts 31 slide towards the end closer to the center of the hanger 2. During the sliding process, each pressing part 31 drives the corresponding two overlapping blocks 32 to extend into the hanger 2, and the first elastic element 33 is compressed. At this time, the upper end of the hanger 2 can be inserted into the chassis 1, so that the upper end of the hanger 2 is inserted into the chassis 1. Then, the pressing of the two pressing parts 31 is released, and each first elastic element 33 is reset, so that the two pressing parts 31 slide towards the end away from the center of the hanger 2, thereby driving the corresponding two overlapping blocks 32 to extend out of the hanger 2. Each overlapping block 32 overlaps with the overlapping ring 11 to realize the installation of the ceiling light. It should be noted that at this time, the four overlapping blocks 32 overlap with the overlapping ring 11, which can ensure the stability of the installation of large-size ceiling lights, and at the same time improve the stability of the installation of small-size ceiling lights, thus making it more versatile.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
