[0001] The present invention belongs to the technical field of lighting, and more specifically, relates to a quick disassembly and assembly device and a lamp. Background Art

[0002] A ceiling lamp is a type of lamp. As the name implies, it is called a ceiling lamp because the upper part of the lamp is relatively flat and the bottom is completely attached to the ceiling during installation. The light sources include ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, tungsten halogen lamps, LEDs (Light-Emitting Diodes), etc. Currently, the most popular ceiling lamp in the market is the LED ceiling lamp, which is a frequently selected lamp for various places such as homes, offices, and entertainment venues.

[0003] The existing ceiling lamp includes a lampshade and a lamp base, and the lamp base is installed on the ceiling by screws. Therefore, when disassembling and assembling the ceiling lamp, it is necessary to first remove the lampshade and then turn the screws to fix the lamp base on the ceiling or remove it from the ceiling. It can be seen that the disassembly and assembly of the ceiling lamp with the above structure are complicated, reducing the disassembly and assembly efficiency. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a quick disassembly and assembly device and a lamp to solve the technical problems of complicated disassembly and assembly and low disassembly and assembly efficiency of ceiling lamps in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: providing a quick disassembly and assembly device, including:

[0006] A hanging device, the hanging device is provided with a buckle, the buckle has two states of popping out and retracting in the hanging device, the buckle always has a tendency to pop out in the hanging device, and the buckle is provided with an abutting portion;

[0007] An installation component, rotatably assembled on the hanging device, the installation component is provided with an operation portion and a blocking portion along the assembly direction, and the buckle is located between the operation portion and the blocking portion;

[0008] The installation component and the hanging device can move relative to each other along the assembly direction, so that the operation portion can contact or separate from the abutting portion;

[0009] When the operation portion contacts the abutting portion, the installation component rotates relative to the hanging device, and the operation portion can squeeze the abutting portion and make the buckle switch between the two states of popping out and retracting;

[0010] When the hook is ejected, the blocking portion abuts against the hook to prevent the installation component from detaching from the hook along the assembly direction; when the hook is retracted, the hook avoids the blocking portion to allow the installation component to detach from the hook along the assembly direction.

[0011] In one embodiment, the installation assembly includes a lamp holder and a lamp panel that are assembled in sequence along the assembly direction. The lamp holder and the lamp panel together form an installation groove, and the hanger is assembled in the installation groove.

[0012] In one embodiment, the blocking portion is provided on the lamp panel, and the operating portion is provided on the lamp holder.

[0013] In one embodiment, the quick disassembly and assembly device further comprises an elastic component, which is arranged between the lamp holder and the hanger along the assembly direction, and the elastic component is used to ensure that the lamp holder always tends to move away from the hanger.

[0014] In one embodiment, the elastic component includes a stop ring abutting against the hanger and an elastic member provided between the stop ring and the lamp holder.

[0015] In one embodiment, the stop ring is provided with a stop block protruding radially inward, and the stop block is used to block the abutment portion to limit the rotation of the mounting assembly relative to the hanger.

[0016] In one embodiment, the elastic component further includes a connecting shaft for connecting the stop ring and the lamp holder, the connecting shaft extends along the assembly direction, and the lamp holder can slide along the connecting shaft.

[0017] In one embodiment, when the operating portion contacts the abutting portion, the operating portion is radially disposed outside the abutting portion, and the operating portion is provided with a guiding surface for pressing the abutting portion.

[0018] In one embodiment, the guide surface includes a first guide segment and a second guide segment connected in sequence;

[0019] When the abutting portion moves from the end of the first guide segment away from the second guide segment toward the other end of the first guide segment, the buckle gradually retracts in the hook guide;

[0020] When the second guide section abuts against the abutting portion, the buckle retracts in the hook guide.

[0021] The present invention further provides a lamp, comprising a light-emitting assembly, a lampshade, and the above-mentioned quick disassembly and assembly device, wherein the lampshade is arranged on the mounting assembly, and the light-emitting assembly is arranged between the mounting assembly and the lampshade.

[0022] The beneficial effects of the quick disassembly and assembly device and the lamp provided by the present invention are as follows: Compared with the prior art, the hanging device of the present invention is used to be fixed on the bearing target, and the installation component is used to fix the lamp shade and the light-emitting component. When the hanging device and the installation component are assembled, first press the buckle so that the buckle retracts into the hanging device to avoid the blocking part of the installation component. Then, assemble the installation component on the hanging device. When the buckle passes over the blocking part, the buckle pops out in the hanging device and abuts against the blocking part to prevent the installation component from detaching from the hanging device along the assembly direction, thereby completing the assembly between the hanging device and the installation component. When the hanging device and the installation component are disassembled, first move the installation component along the assembly direction and relative to the hanging device until the operating part of the installation component contacts the abutting part of the buckle. Then, rotate the installation component, and the operating part squeezes the abutting part and causes the buckle to retract in the hanging device to avoid the blocking part. Finally, pull the installation component off the hanging device, thereby completing the disassembly between the hanging device and the installation component. Thus, it can be seen that the present invention changes the installation thinking and steps of traditional ceiling lamps. When this quick disassembly and assembly device is applied to lamps, the lamp shade is fixed on the installation component. When disassembling the lamp, it is not necessary to remove the lamp shade, and the lamp can be removed by screwing the installation component. The disassembly and assembly of the hanging device and the installation component of the present invention are simple and convenient, which can effectively save labor and improve the disassembly and assembly efficiency, and can also avoid damaging components during the disassembly process, improving the reliability of the product.

[0039] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 6 An embodiment of the present invention provides a quick disassembly and assembly device, comprising a hanger 100 and a mounting assembly 200. The hanger 100 is used to be fixed to a load-bearing target, which may be, but is not limited to, a ceiling. The mounting assembly 200 is used to fix a light-emitting assembly 400 and a lampshade 500. The lampshade 500 is fixedly connected to the mounting assembly 200. The lampshade 500 and the mounting assembly 200 enclose a light-emitting cavity 600, and the light-emitting assembly 400 is disposed within the light-emitting cavity 600. When using the quick disassembly and assembly device according to the embodiment of the present invention, the light-emitting assembly 400 is fixed to the mounting assembly 200, and then the lampshade 500 is fixed to the mounting assembly 200, so that the light-emitting assembly 400 is disposed in the light-emitting cavity 600 between the mounting assembly 200 and the lampshade 500.

[0040] Further, as a specific embodiment of the present invention, Figure 4 As shown, the hook guide 100 is provided with a buckle 110, which has two states of pop-up and retraction in the hook guide 100. The buckle 110 always has a tendency to pop out in the hook guide 100, and the buckle 110 is provided with an abutment portion 111; Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the mounting assembly 200 can be rotatably assembled to the hanger 100. The mounting assembly 200 is provided with an operating portion 221 and a blocking portion 211 along the assembly direction, and the buckle 110 is located between the operating portion 221 and the blocking portion 211; the mounting assembly 200 and the hanger 100 can move relative to each other along the assembly direction so that the operating portion 221 can contact or separate from the abutting portion 111; when the operating portion 221 contacts the abutting portion 111, the mounting assembly 200 rotates relative to the hanger 100, and the operating portion 221 can press the abutting portion 111 and switch the buckle 110 between the ejection and retraction states; when the buckle 110 ejects the hanger 100, the blocking portion 211 abuts against the buckle 110 to prevent the mounting assembly 200 from separating from the hanger 100 along the assembly direction; when the hanger 100 retracts, the buckle 110 avoids the blocking portion 211, so that the mounting assembly 200 can separate from the hanger 100 along the assembly direction.

[0041] The hanging device 100 is fixed to the ceiling. The mounting assembly 200 is fixedly connected to the light-emitting assembly 400 and the lamp shade 500. The steps of assembling the hanging device 100 and the mounting assembly 200 are as follows: As Figure 6 shown, first press the buckle 110 so that the buckle 110 retracts into the hanging device 100 to avoid the blocking portion 211 of the mounting assembly 200; then, assemble the mounting assembly 200 onto the hanging device 100. When the buckle 110 passes over the blocking portion 211, the buckle 110 pops out in the hanging device 100. Under the action of gravity, the mounting assembly 200 always has a tendency to move downward (in the same direction as the direction of gravity) relative to the hanging device 100, so that the blocking portion 211 abuts against the buckle 110 to prevent the mounting assembly 200 from detaching from the hanging device 100 along the assembly direction, thus completing the assembly between the hanging device 100 and the mounting assembly 200; Obviously, in the above assembly process, there is no need to remove the lamp shade 500, which simplifies the assembly steps, can effectively save labor and improve the assembly efficiency.

[0042] The steps of disassembling the hanging device 100 and the mounting assembly 200 are as follows: As Figure 6 shown, first move the mounting assembly 200 along the assembly direction and relative to the hanging device 100. Specifically, press the mounting assembly 200 upward (opposite to the direction of gravity) so that the mounting assembly 200 moves upward relative to the hanging device 100 until the operating portion 221 of the mounting assembly 200 contacts the abutting portion 111 of the buckle 110; then, as Figures 7 to 9 shown, rotate the mounting assembly 200, the operating portion 221 presses against the abutting portion 111 and causes the buckle 110 to retract in the hanging device 100 to avoid the blocking portion 211; finally, pull the mounting assembly 200 off the hanging device 100, thus completing the disassembly between the hanging device 100 and the mounting assembly 200; Obviously, in the above disassembly process, there is no need to remove the lamp shade 500, which changes the installation thinking and steps of the traditional ceiling lamp, simplifies the disassembly steps, can effectively save labor and improve the disassembly efficiency, can make the lamp shade 500 into one body, saves the mold opening cost and the assembly cost, does not need to remove the lamp shade 500 during disassembly, and avoids damaging components during the disassembly work, improving the reliability of the product.

[0043] Thus, it can be seen that the hanging device 100 and the mounting assembly 200 of the present invention are easy to disassemble and assemble, can effectively save labor and improve the disassembly and assembly efficiency.

[0044] Furthermore, as a specific embodiment of the present invention, the hanging device 100 is provided with a pop-up mechanism (not shown in the figure). The pop-up mechanism is connected to the buckle 110 and the hanging device 100, so that the buckle 110 always has a tendency to pop out in the hanging device 100. In this embodiment, the pop-up mechanism can be but is not limited to a spring.

[0045] Further, as a specific embodiment of the present invention, as Figure 3 and Figure 4 shown, the hanger 100 is provided with two buckles 110, and the two buckles 110 are symmetrically arranged on opposite sides of the hanger 100. Correspondingly, the mounting assembly 200 is provided with two operating parts 221, and the operating parts 221 and the buckles 110 are in one-to-one correspondence. Each operating part 221 is used to squeeze the corresponding buckle 110 to make the buckle 110 pop out or retract in the hanger 100. It can be understood that, according to the selection of the actual situation and specific requirements, the number of the buckles 110 and the operating parts 221 can be appropriately adjusted, and this is not uniquely limited here.

[0046] Further, as a specific embodiment of the present invention, as Figure 2 、 Figure 5 and Figure 6 shown, the mounting assembly 200 includes a lamp base 220 and a lamp panel 210 assembled in sequence along the assembly direction. The lamp base 220 and the lamp panel 210 enclose to form a mounting groove 230, and the hanger 100 is assembled in the mounting groove 230. In this embodiment, the lamp panel 210 and the lamp shade 500 are fixedly connected and enclose to form a light-emitting cavity 600. The lamp base 220 can be fixed to the lamp panel 210 by, but not limited to, screws, rivets or pull rivets. The blocking part 211 is arranged on the lamp panel 210, and the blocking part 211 is located at the top of the mounting groove 230; the operating part 221 is arranged on the lamp base 220, and the operating part 221 is located at the bottom of the mounting groove 230. It can be understood that, according to the selection of the actual situation, the specific structure of the mounting assembly 200 can be appropriately modified as long as it is ensured that the mounting assembly 200 is provided with the blocking part 211 and the operating part 221, and this is not uniquely limited here.

[0047] Further, as a specific embodiment of the present invention, as Figure 6 shown, the distance between the blocking part 211 and the operating part 221 is greater than the height of the buckle 110, so that the mounting assembly 200 and the hanger 100 can move relative to each other along the assembly direction. It should be noted that the distance between the blocking part 211 and the operating part 221 refers to the dimension in the assembly direction between the blocking part 211 and the operating part 221, and the height of the buckle 110 refers to the dimension of the buckle 110 in the assembly direction.

[0048] Further, as a specific embodiment of the present invention, as Figure 6 shown, when the operating part 221 contacts the abutting part 111, the operating part 221 is arranged radially outside the abutting part 111, and the operating part 221 is provided with a guiding surface 2211 for squeezing the abutting part 111. It should be noted that the axis defined by the mounting assembly 200 rotating relative to the hanger 100 is the rotation axis, and the radial direction refers to the direction perpendicular to and passing through the rotation axis.

[0049] Further, as a specific embodiment of the present invention, as Figure 6 shown, the guiding surface 2211 includes a first guiding segment 2211a and a second guiding segment 2211b connected in sequence. When the abutting portion 111 moves from one end of the first guiding segment 2211a away from the second guiding segment 2211b towards the other end of the first guiding segment 2211a, the buckle 110 gradually retracts in the hanger 100; when the second guiding segment 2211b abuts against the abutting portion 111, the buckle 110 retracts in the hanger 100. In this structure, as Figure 6 and Figure 8 shown, the mounting assembly 200 is moved along the assembly direction and relative to the hanger 100. Specifically, the mounting assembly 200 is pressed upward (opposite to the direction of the action of gravity), so that the mounting assembly 200 moves upward relative to the hanger 100 until the first guiding segment 2211a of the mounting assembly 200 contacts the abutting portion 111 of the buckle 110. Then, the mounting assembly 200 is rotated so that the abutting portion 111 moves from one end of the first guiding segment 2211a away from the second guiding segment 2211b towards the other end of the first guiding segment 2211a, and the buckle 110 gradually retracts in the hanger 100; as Figure 9 shown, when the abutting portion 111 abuts against the second guiding segment 2211b, the buckle 110 is fully retracted in the hanger 100. At this time, the mounting assembly 200 can be directly pulled off the hanger 100.

[0050] Further, as a specific embodiment of the present invention, as Figures 7 to 9 shown, the first guiding segment 2211a is an arc surface or an inclined surface. In this structure, when the abutting portion 111 moves from one end of the first guiding segment 2211a away from the second guiding segment 2211b towards the other end of the first guiding segment 2211a, the buckle 110 gradually retracts in the hanger 100; the second guiding segment 2211b is an arc surface. In this structure, when the abutting portion 111 moves along the second guiding segment 2211b, the buckle 110 always remains in a fully retracted state in the hanger 100.

[0051] Further, as a specific embodiment of the present invention, as Figures 6 to 9 shown, the operating portion 221 further includes a stopper 2212 protruding from the second guiding segment 2211b. The stopper 2212 can be specifically but not limited to being disposed at one end of the second guiding segment 2211b away from the first guiding segment 2211a. The stopper 2212 is used to block the abutting portion 111 to prevent the abutting portion 111 from slipping off from one end of the second guiding segment 2211b away from the first guiding segment 2211a, and to avoid the buckle 110 popping out in the hanger 100.

[0052] Further, as a specific embodiment of the present invention, as Figures 6 to 9As shown, the operation part 221 further includes a third guiding section 2211c connected to one end of the first guiding section 2211a that is far from the second guiding section 2211b. The third guiding section 2211c is used to guide the abutting part 111 to move to the second guiding section 2211b. In this embodiment, the third guiding section 2211c can be an arc surface.

[0053] Further, as a specific embodiment of the present invention, as Figures 6 to 9 shown, the operation part 221 further includes an elastic piece 2213 disposed on the guiding surface 2211. In this structure, when the abutting part 111 moves along the guiding surface 2211, if the abutting part 111 passes through the elastic piece 2213, the elastic piece 2213 will first undergo elastic deformation, and then the elastic piece 2213 will rebound to restore its initial state, emitting a sound and a vibrating tactile sensation to prompt the operator to remove the installation component 200. In this embodiment, the elastic piece 2213 can be, but is not limited to, disposed on the third guiding section 2211c.

[0054] Further, as a specific embodiment of the present invention, as Figure 2 and Figure 6 shown, the quick disassembly and assembly device further includes an elastic component 300. The elastic component 300 is disposed between the lamp holder 220 and the hanging device 100 along the assembly direction. The elastic component 300 is used to make the lamp holder 220 always have a tendency to move away from the hanging device 100. In this structure, when an earthquake or other accident causes the installation component 200 to vibrate and rotate relative to the hanging device 100, the elastic component 300 can maintain the distance between the operation part 221 and the abutting part 111, and the installation component 200 will not fall due to an earthquake or other external forces, ensuring the safety of the quick disassembly and assembly device.

[0055] Further, as a specific embodiment of the present invention, as Figure 2 and Figure 6 shown, the elastic component 300 includes a rotation-stopping ring 310 abutting against the hanging device 100 and an elastic member 320 disposed between the rotation-stopping ring 310 and the lamp holder 220. In this structure, both ends of the elastic member 320 respectively abut against the rotation-stopping ring 310 and the lamp holder 220. Under the elastic force of the elastic member 320, the rotation-stopping ring 310 also abuts against the rotation-stopping ring 310. It can be understood that according to the selection of the actual situation and specific requirements, the specific structure of the elastic component 300 can be appropriately modified as long as it is ensured that the installation component 200 is provided with a blocking part 211 and an operation part 221, and no unique limitation is made here.

[0056] Further, as a specific embodiment of the present invention, the elastic member 320 may, but is not limited to, be a spring, and the number of the elastic members 320 may be at least one. Preferably, the number of the elastic members 320 is at least two to ensure that the distance between the operating portion 221 and the abutting portion 111 is stably maintained without manual action. Of course, according to the actual situation and specific requirements, the number of the elastic members 320 can be appropriately adjusted and is not uniquely limited herein.

[0057] Further, as a specific embodiment of the present invention, as Figure 2 and Figure 6 shown, the anti-rotation ring 310 is provided with an anti-rotation block 311 protruding radially inward. The anti-rotation block 311 is used to block the abutting portion 111 to limit the rotation of the mounting assembly 200 relative to the hanging device 100, so as to avoid the wire of the lighting assembly 400 being wound or broken due to the idle rotation of the mounting assembly 200.

[0058] Further, as a specific embodiment of the present invention, as Figure 2 and Figure 6 shown, the elastic assembly 300 further includes a connecting shaft 330 for connecting the anti-rotation ring 310 and the lamp holder 220. The connecting shaft 330 extends along the assembly direction, and the lamp holder 220 can slide along the connecting shaft 330. In this embodiment, one end of the connecting shaft 330 is fixed to the anti-rotation ring 310, and the other end is provided with an anti-detachment head 331. The lamp holder 220 is provided with a through hole 222 for the connecting shaft 330 to pass through. The outer diameter of the anti-detachment head 331 is greater than the aperture of the through hole 222, which can prevent the lamp holder 220 from detaching from the connecting shaft 330 and fix the anti-rotation ring 310 and the lamp holder 220 together.

[0059] Further, as a specific embodiment of the present invention, the connecting shaft 330 may be a screw, a rivet or a pull nail. Of course, according to the actual situation and specific requirements, the connecting shaft 330 may also be other locking elements.

[0060] Further, as a specific embodiment of the present invention, the number of the connecting shafts 330 may be at least one. Preferably, the number of the connecting shafts 330 is at least two. Of course, according to the actual situation and specific requirements, the number of the connecting shafts 330 can be appropriately adjusted and is not uniquely limited herein.

[0061] Further, as a specific embodiment of the present invention, the elastic member 320 is sleeved outside the connecting shaft 330, so that the elastic member 320 is stably arranged between the anti-rotation ring 310 and the lamp holder 220. Of course, according to the actual situation and specific requirements, the elastic member 320 can be arranged between the anti-rotation ring 310 and the lamp holder 220 in other ways and is not uniquely limited herein.
