Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a modular lighting fixture quick-plug structure. Background Technology

[0002] Modular luminaires are lighting devices that employ a modular design, allowing for flexible lighting solutions through the combination of independent modules. Their core feature is the separate design of the light source, heat dissipation structure, and driver power supply, facilitating maintenance and functional expansion. Modular luminaires consist of an LED light source, a heat dissipation housing, and an independent driver power supply module. The driver power supply module uses a standardized interface design and can be replaced individually without disassembling the entire luminaire. Compared to traditional integrated luminaires, modular luminaires offer advantages such as convenient maintenance, flexible expansion, and energy efficiency, making them widely used in various scenarios including furniture decoration, commercial lighting, and outdoor scene construction.

[0003] However, existing modular lighting fixtures are often difficult to plug in and unplug, making installation and disassembly very cumbersome for users. Furthermore, these modular fixtures cannot meet the requirements for stable installation, making them very inconvenient for temporary relocation of the entire fixture. Utility Model Content

[0004] In order to improve the structure of modular lighting fixtures, making them easier to install and disassemble while ensuring a stable connection, this application provides a quick-plug structure for modular lighting fixtures.

[0005] The modular lighting fixture quick-plug structure provided in this application adopts the following technical solution:

[0006] A modular luminaire quick-plug structure includes,

[0007] The mounting bracket includes a frame and several horizontal and vertical bars connected to the inner side of the frame. The horizontal and vertical bars are perpendicular to each other and staggered. Two adjacent horizontal bars and two adjacent vertical bars at the same position together form a mounting cavity for placing the lamp body.

[0008] A fixed frame, which is rotatably connected to the mounting frame;

[0009] The sliding plate has symmetrical grooves on two vertical rods on both sides of the mounting cavity, and the two sliding plates slide through the two grooves respectively;

[0010] A telescopic shaft, comprising a sleeve shaft and a core shaft slidably passing through one end of the sleeve shaft, the sleeve shaft being perpendicularly connected to the slide plate, the core shaft passing into the mounting cavity, and a tension spring connecting the core shaft and the sleeve shaft;

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a modular lighting fixture quick-plug structure.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A modular luminaire quick-plug structure, comprising:

[0035] Mounting frame 1 includes a frame 11 and several horizontal bars 12 and vertical bars 13 connected to the inner side of the frame 11. The several horizontal bars 12 and several vertical bars 13 are perpendicular to each other and staggered. Two adjacent horizontal bars 12 and two adjacent vertical bars 13 at the same position together form a mounting cavity 2 for placing the lamp body.

[0036] Fixed frame 3 is rotatably connected to mounting frame 1;

[0037] The sliding plate 4 has symmetrical grooves 131 on the two vertical rods 13 on both sides of the mounting cavity 2, and the two sliding plates 4 slide through the two grooves 131 respectively.

[0038] Telescopic shaft 5 includes a sleeve shaft 51 and a spindle 52 that slides through one end of the sleeve shaft 51. The sleeve shaft 51 is perpendicularly connected to the slide plate 4. The spindle 52 is inserted into the mounting cavity 2. A tension spring 53 is connected between the spindle 52 and the sleeve shaft 51.

[0039] Movable plate 521, which is hinged to the end of spindle 52;

[0040] Sleeve 511, sleeve 511 is slidably fitted with sleeve shaft 51 and abuts against movable plate 521;

[0041] Pressure plate 41 is slidably mounted on slide plate 4 and is connected to slide plate 4 by spring 42;

[0042] Connecting shaft 6 is located on the other side of pressure plate 41 and its end is hinged to movable plate 521.

[0043] The bending plate 7 has two ends located between the slide plate 4 and the sleeve 511 and between the slide plate 4 and the pressure plate 41, respectively, and an adjusting torsion spring 71 is connected between the bending plate 7 and the slide plate 4.

[0044] When the lamp body is not installed, the distance between the end of the connecting shaft 6 and the slide plate 4 is greater than the distance between the end of the spindle 52 and the slide plate 4.

[0045] With the above structural design, during the installation of the lamp body, as the lamp body is continuously inserted into the mounting cavity 2, the movable plate 521 will gradually become more vertical. At this time, one end of the bending plate 7 presses down, while the other end drives the entire movable part to move outward, thus limiting the position of the lamp body.

[0046] Meanwhile, a positioning groove 121 is provided on the crossbar 12 at the position of each mounting cavity 2, and a positioning hole 122 is provided on the bottom side of the positioning groove 121.

[0047] Preferably, the two movable plates 521 located in the same mounting cavity 2 are provided with transverse anti-slip textures 5211 on the side that is close to each other, so as to enhance the limiting effect on the lamp body and prevent slippage.

[0048] Reference Figure 4 and Figure 6 Each mounting cavity 2 on the mounting bracket 1 is equipped with a positioning component 8 for longitudinal positioning of the lamp body. The positioning component 8 specifically includes a positioning block 81 movably disposed in the positioning groove 121 and a connecting rod 82 connected to the positioning block 81. The connecting rod 82 is slidably disposed within the positioning hole 122 and connected to the bottom side of the positioning hole 122 by a compression spring 821. When the lamp body enters the mounting cavity 2, it continuously compresses the positioning block 81, causing it to retract into the positioning hole 122. Due to the action of the compression spring 821, the positioning block 81 applies a reverse force to the lamp body, thereby longitudinally limiting the lamp body.

[0049] Reference Figure 6 Furthermore, an eccentric wheel 811 is rotatably mounted on the positioning block 81, and an anti-slip pad 8111 is installed on the outer surface of the eccentric wheel 811. Simultaneously, the minimum diameter of the eccentric wheel 811 is equal to the distance from its center to the end of the positioning block 81. This ensures that when the lamp body moves into the mounting cavity 2, it drives the eccentric wheel 811 to rotate, causing the distance between the contact point between the eccentric wheel 811 and the lamp body and the center of the eccentric wheel 811 to gradually increase. This ultimately increases the elastic potential energy of the compression spring 821 and provides greater compressive force to the lamp body. A return torsion spring connects the eccentric wheel 811 and the positioning block 81 for the return of the eccentric wheel 811.

[0050] Reference Figure 6 Preferably, the spring force of the compression spring 821 is greater than that of the return torsion spring, and the eccentric wheel 811 and the positioning block 81 can be completely retracted into the positioning groove 121. This design makes it less likely for the eccentric wheel 811 to slip and push the lamp body out of the mounting cavity 2, while also allowing this application to adapt to more lamp bodies of different sizes.

[0051] Reference Figure 5 and Figure 6 Several rollers 9 are rotatably mounted on the crossbar 12 at the position of the mounting cavity 2 relative to the other side of the positioning block 81, and all rollers 9 are tangent to the inner wall of the mounting cavity 2. The function of this structure is to change sliding into rolling, protect the structural integrity of the lamp body, and at the same time improve the convenience of lamp body installation and disassembly.

[0052] The implementation principle of the modular lighting fixture quick-plug structure in this application is as follows:

[0053] In the horizontal direction, when the lamp body enters the mounting cavity 2, the movable frame is compressed and gradually becomes parallel to the side of the lamp body. At this time, the bending plate 7 is compressed by the connecting shaft 6, causing its other end to lift up. Under this action, the sleeve 511 is pushed up by the other end of the bending plate 7, making the movable plate 521 fit tightly against the lamp body. The two movable plates work together to limit the position of the lamp body.

[0054] Vertically, as the lamp body moves continuously into the mounting cavity 2, it continuously drives the eccentric wheel 811 to rotate. The rotation of the eccentric wheel 811 causes the distance between its farthest point and the center to continuously increase, thereby increasing the elastic potential energy of the compression spring 821. Under the action of the compression spring 821, the lamp body is continuously pressed closer.

[0055] 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.
