Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a quick-assembly lighting fixture. Background Technology

[0002] LED (Light Emitting Diode) is a solid-state semiconductor device that converts electrical energy into visible light; it directly converts electricity into light. The heart of an LED is a semiconductor chip, with one end attached to a support, serving as the negative electrode, and the other end connected to the positive electrode of the power supply. The entire chip is encapsulated in epoxy resin. LED lampshades are a type of LED accessory, designed to better focus and soften the light, preventing direct, glaring illumination. With use, dust accumulates on the lampshade's outer shell, and insects can infest the inside, affecting the lighting effect and aesthetics of the lamp.

[0003] Chinese utility model patent application CN202022693357.6 discloses an easy-to-clean LED lampshade, including a mounting base, an LED lamp body, and a lampshade body. The lampshade body includes a spherical shell and a cylindrical neck. The top of the cylindrical neck is detachably threaded to the bottom of the mounting base. A rotatable sleeve is provided between the bottom of the mounting base and the spherical shell, fitted around the outer circumference of the cylindrical neck. The left and right ends of the bottom of the sleeve are respectively hinged to arc-shaped cleaning brushes that can be folded up and down. The cleaning brushes are adapted to the outer surface of the spherical shell and extend to the middle of the bottom of the spherical shell. The cleaning brushes can fit tightly against the outer surface of the spherical shell, and replaceable cleaning swabs are provided on the arc-shaped opposite surface of the spherical shell. By providing a rotatable sleeve on the LED lampshade, and the sleeve being hinged to the foldable cleaning brushes, rotating the sleeve drives the two cleaning brushes to wipe the dust layer on the lampshade body, increasing the cleaning speed and improving the ease of cleaning.

[0004] However, the two cleaning brushes can only wipe the dust on the outside of the lampshade, not the inside. Furthermore, the lampshade is difficult to disassemble, which further complicates cleaning the inside of the lampshade and replacing the light source. Utility Model Content

[0042] Example:

[0043] like Figures 1 to 3 As shown, a quick-assembly lighting fixture includes:

[0044] Ceiling plate 1;

[0045] Linkage assembly 2, the linkage assembly 2 includes a vertical rod 21 connected to the ceiling plate 1 and a mounting plate 22 disposed below the vertical rod 21;

[0046] Lamp cup 3, which is disposed below the mounting plate 22;

[0047] LED light source 4, which is installed inside the lamp cup 3;

[0048] Lamp cover 5, the lamp cover 5 being disposed outside the LED light source 4;

[0049] And a connecting component 6, which connects the lampshade 5 and the connecting rod assembly 2, including a top cover unit 61 that is slidably sleeved on the outside of the vertical rod 21, a number of pressure rod units 62 that are arranged in a circumferential array and rotatably installed at the edge of the mounting plate 22, and an adjustment unit 63 for controlling the contact and separation of the top cover unit 61 and the pressure rod units 62;

[0050] The pressure rod unit 62 is a lever structure. The top cover unit 61 abuts against several sets of pressure rod units 62. The pressure rod unit 62 and the top cover unit 61 abut against the inner wall and outer wall of the lampshade 5 respectively to fix the lampshade 5.

[0051] It should be noted that both the lamp cup 3 and the LED light source 4 are existing technologies and will not be described in detail in this utility model.

[0052] Furthermore, the lampshade 5 is configured as a sphere.

[0053] It should be noted that the lampshade 5 is spherical, and the spherical structure is a symmetrical structure with uniform weight distribution, which makes it easy to lift the lamp with one hand during disassembly and assembly.

[0054] It should also be noted that the length of the vertical rod 21 can be selected according to the customer's needs.

[0055] It is worth mentioning that the top of the lampshade 5 has an opening for the pressure rod unit 62 to enter its interior.

[0056] Furthermore, such as Figure 3 As shown, the top cover unit 61 includes a top cover body 611, a pressure block 612 coaxially disposed below the top cover body 611 and slidably sleeved on the vertical rod 21, a sleeve 613 coaxially disposed above the top cover body 611 and surrounding the vertical rod 21, a baffle 614 disposed on the vertical rod 21 and located inside the sleeve 613, and a spring a615 sleeved on the vertical rod 21 and located between the pressure block 612 and the baffle 614.

[0057] It should be noted that the contact surface between the top cover body 611 and the lampshade 5 is consistent with the outline of the lampshade 5.

[0058] Furthermore, such as Figure 3 As shown, the pressure bar unit 62 includes a mounting shaft 621 disposed at the edge of the mounting plate 22 and a pressure bar 622 rotatably mounted on the mounting shaft 621 and capable of abutting against the pressure block 612.

[0059] Furthermore, the clamping rod 622 includes a power arm 6221 located above the mounting shaft 621 and whose end can abut against the pressure block 612, and a clamping arm 6222 located below the mounting shaft 621 and can abut against the inner wall of the lamp cover 5, wherein the clamping arm 6222 is longer than the power arm 6221.

[0060] It should be noted that the clamping arm 6222 is relatively long, so that after the pressure block 612 disengages from the power arm 6221, the clamping arm 6222 rotates downward, the power arm 6221 tilts up, and the lamp cover 5 can be removed.

[0061] Furthermore, the clamping arm 6222 is elastically configured.

[0062] It should be noted that the clamping arm 6222 is elastically designed so that the clamping arm 6222 fits more tightly against the inner wall of the lampshade 5.

[0063] Furthermore, the adjustment unit 63 includes a guide portion 631 disposed at the lower edge of the baffle 614, a plurality of wedge rods 632 arranged in a circumferential array and reciprocatingly sliding along the sleeve 613 radially, a spring b633 connecting the tail of the wedge rods 632, a top plate 634 mounted on the vertical rod 21 and disposed above the baffle 614, a movable plate 635 slidably disposed on the vertical rod 21 and disposed between the top plate 634 and the baffle 614, and a spring c636 for the movable plate 635 and the top plate 634.

[0064] Furthermore, such as Figure 4 As shown, the wedge-shaped rod 632 is positioned with its wedge-shaped surface facing upwards; the movable plate 635 is a conical structure with a smaller top and a larger bottom, and its bottom surface can be fitted to the upper surface of the baffle 614.

[0065] It should be noted that the diameter of the movable plate 635 is consistent with the diameter of the baffle 614, thereby allowing the wedge rod 632 to pass over the baffle 614.

[0066] Furthermore, the spring constant of spring a615 is greater than that of spring b633, and the spring constant of spring b633 is greater than that of spring c636.

[0067] It should be noted that the wedge-shaped surface of the wedge rod 632 is positioned upwards so that when the sleeve 613 moves upwards, the wedge rod 632 contacts the baffle 614, the spring b633 is compressed, and the wedge rod 632 passes over the baffle 614. At this time, the spring a615 is in a compressed state. Due to the contact between the upper surface of the baffle 614 and the wedge rod 632, the pressure block 612 will not contact the pressure rod unit 62 downwards. The pressure rod unit 62 is in a free state, thus allowing the lampshade 5 to be removed smoothly, and ensuring that the sleeve 613 does not move downwards, facilitating the installation of the lampshade 5.

[0068] It should be further explained that when installing the lampshade 5, the pressure rod unit 62 needs to be inserted into the lampshade 5, then the lampshade 5 is lifted and moved upward to contact the top cover body 611, and the sleeve 613 is moved upward. The spring a615 continues to be compressed, the wedge rod 632 contacts the moving plate 635, the spring c636 is compressed, then the spring c636 is compressed to its limit position, the spring b633 is compressed, the wedge rod 632 passes over the moving plate 635 and contacts the inclined surface of the moving plate 635, and then the lampshade 5 is lifted. With the hand pointing downwards, spring a615 extends, wedge rod 632 drives moving plate 635 downwards, spring c636 extends, then the bottom surface of moving plate 635 abuts against the upper surface of baffle 614, spring b633 is compressed, wedge rod 632 moves below baffle 614, then lampshade 5 continues to move downwards, pressure block 612 abuts against power arm 6221, and drives clamping arm 6222 to move upwards to abut against the inner wall of lampshade 5, finally clamping arm 6222 cooperates with top cover body 611 to fix lampshade 5.

[0069] It is worth mentioning that the lampshade 5 can be disassembled and assembled using only one hand.

[0070] It is important to note that the spring coefficients of the three types of springs are set in accordance with the disassembly and assembly process of the lampshade 5.

[0071] Furthermore, such as Figure 2 As shown, a retractable sleeve 7 is also provided between the top cover unit 61 and the suction plate 1, and the sleeve 7 is located on the outside of the vertical rod 21.

[0072] It should be noted that the sleeve 7 prevents the interior of the sleeve 613 from being exposed and increases the aesthetics of the lamp.

[0073] Work process:

[0074] like Figure 5 As shown, the disassembly process of the lampshade 5 is as follows: Push the lampshade 5 upward with one hand, causing the top cover unit 61 to move upward. When the sleeve 613 moves upward, the wedge-shaped rod 632 is set with its wedge-shaped surface facing upward, so that when the wedge-shaped rod 632 moves upward, it contacts the baffle 614, and the spring b633 is compressed. The wedge-shaped rod 632 passes over the baffle 614. At this time, the spring a615 is in a compressed state. Since the upper surface of the baffle 614 is in contact with the wedge-shaped rod 632, the pressure block 612 will not contact the pressure rod unit 62 downward. The pressure rod unit 62 is in a free state, and the lampshade 5 can be removed smoothly.

[0075] like Figures 6 to 8 As shown, the installation process of the lampshade 5 is as follows: the pressure rod unit 62 is inserted into the lampshade 5, then the lampshade 5 is lifted and moved upward to contact the top cover body 611, and the sleeve 613 is moved upward. The spring a615 continues to be compressed, the wedge rod 632 contacts the moving plate 635, the spring c636 is compressed, then the spring c636 is compressed to its limit position, the spring b633 is compressed, the wedge rod 632 passes over the moving plate 635 and contacts the inclined surface of the moving plate 635, and then the hand lifting the lampshade 5 moves towards... When the spring a615 extends, the wedge rod 632 drives the moving plate 635 to move downward, the spring c636 extends, and then the bottom surface of the moving plate 635 abuts against the upper surface of the baffle 614, the spring b633 is compressed, the wedge rod 632 moves to below the baffle 614, and then the lampshade 5 continues to move downward, the pressure block 612 abuts against the power arm 6221, and drives the clamping arm 6222 to move upward and abut against the inner wall of the lampshade 5. Finally, the clamping arm 6222 cooperates with the top cover body 611 to fix the lampshade 5.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
