Description

Technical Field

[0001] The utility model relates to a fixed lamp, in particular to a fixed lamp which can be quickly installed and disassembled. Background Art

[0002] Existing fixed lamps usually include a mounting plate and a lamp body. During installation, the mounting plate is first fixed to a preset mounting position on the ceiling, and the external power line reserved at the mounting position is led out from the mounting plate. Then, the power line of the lamp body is connected to the external power line through a wiring terminal, or directly connected and insulated. Then, the power line of the lamp body and the external power line are arranged to avoid interfering with the subsequent fixing of the lamp body and the mounting plate. Finally, the lamp body is fixed to the mounting plate. In existing fixed lamps, the lamp body and the mounting plate are fixed by a rotating buckle structure. After the lamp body and the mounting plate are aligned up and down, the lamp body is rotated to the rotating buckle structure to fix it to the mounting plate to complete the installation.

[0003] However, the shape of the lamp body of the above-mentioned fixed lamps that are currently widely used is generally round or square. When the shape of the lamp body is square, it is generally required that the four sides of the lamp body are parallel to the four walls one by one. Since there is no fine-tuning space for the rotating buckle structure, the position of the lamp body cannot be adjusted after the mounting plate is fixed. As a result, the initial installation position of the mounting plate needs to be relatively precise, that is, the initial installation position of the mounting plate has high requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fixed lamp which can be quickly installed and disassembled and can reduce the requirements for the initial installation position of the installation plate when the shape of the lamp body is square.

[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a fixed lamp that can be quickly installed and disassembled, including a mounting plate and a lamp body, m disassembly and assembly mechanisms are evenly arranged along a circle around the mounting plate, m is an even number greater than or equal to 2, and n elastic telescopic mechanisms are evenly distributed along a circle on the lamp body, n is an even number greater than or equal to 2 and not greater than m, the n elastic telescopic mechanisms can correspond one-to-one with n disassembly and assembly mechanisms among the m disassembly and assembly mechanisms, and each elastic telescopic mechanism can first shrink and move from the bottom to the top of a disassembly and assembly mechanism corresponding to it, and then stretch to be supported by the disassembly and assembly mechanism.

[0006] Each of the disassembly and assembly mechanisms comprises an arc-shaped plate and two first guide ribs, the inner arc surface of the arc-shaped plate is fixed to the outer side surface of the mounting plate, and the two are in a fitted state, the two first guide ribs are arranged on the arc-shaped plate at intervals on the left and right, and the bottoms of the two first guide ribs are fixed to the arc-shaped plate, the inner side surface of each of the first guide ribs is an arc-shaped surface, the inner side surface of each of the first guide ribs is fixed to the outer side surface of the mounting plate, and the two are in a fitted state, the opposite side of the two first guide ribs is its disassembly guide surface, the disassembly guide surface of each of the first guide ribs is an inclined surface, and the spacing between the disassembly guide surfaces of the two first guide ribs increases from the inside to the outside; each of the elastic telescopic mechanisms comprises a mounting seat, a spring and a guide portion, the mounting seat is fixed to the lamp body, and a movable passage with an opening at one end is provided in the mounting seat. The guide portion has four end faces, upper, lower, left and right, the upper end face of one end of the guide portion is its installation guide face, the left end face and the right end face are its disassembly guide faces, and the lower end face is a plane. The installation guide face and the two disassembly guide faces of the guide portion are both inclined faces. The spring is located in the moving channel, the other end of the guide portion is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the mounting seat. The guide portion can compress or stretch the spring when subjected to force and move along the moving channel; the installation guide face of the guide portion is used to cooperate with the bottom of the arc-shaped plate of the disassembly and assembly mechanism to squeeze the spring to make the spring contract, and the two disassembly guide faces of the guide portion are used to match the disassembly guide faces of the two first guide ribs of the disassembly and assembly mechanism in a one-to-one manner to squeeze the spring to make the spring contract.

[0007] An electric kettle type coupler male plug is arranged at the center of the lamp body, and the electric kettle type coupler male plug is connected to the power cord of the lamp body. A through hole is arranged at the center of the mounting plate extending upward and downward, and a wiring terminal and an electric kettle type coupler female plug are arranged at the through hole. The wiring terminal is located above the electric kettle type coupler female plug and is connected to the electric kettle type coupler female plug through a metal spring sheet. The wiring terminal is used to plug in an external power cord.

[0008] The fixed lamp that can be quickly installed and disassembled also includes a plurality of guide mechanisms evenly distributed along a circle, each of the guide mechanisms includes two second guide ribs, the two second guide ribs are arranged at intervals and are fixed on the lamp body, each of the second guide ribs has a guide surface, and its guide surface is composed of an inclined surface and a vertical plane.

[0009] Compared with the prior art, the utility model has the advantage that n disassembly and assembly mechanisms are evenly spaced around the mounting plate, and m elastic telescopic mechanisms are evenly spaced around the mounting plate. The n elastic telescopic mechanisms can correspond to n disassembly and assembly mechanisms among the m disassembly and assembly mechanisms one by one, and each elastic telescopic mechanism can first shrink and move from the bottom to the top of a corresponding disassembly and assembly mechanism, and then stretch to be supported by the disassembly and assembly mechanism. Because there is no other connection between the elastic telescopic mechanism and the disassembly and assembly mechanism, the lamp body and the mounting plate can rotate relatively. At this time, the rotating lamp The main body can adjust its position. When the lamp body needs to be disassembled, first rotate the lamp body until one end of each elastic telescopic mechanism contacts its corresponding disassembly and assembly mechanism, and continue to rotate the lamp body. At this time, each elastic telescopic mechanism is squeezed by its corresponding disassembly and assembly mechanism and shrinks to contact the outer side of the disassembly and assembly mechanism. Thereafter, the lamp body can be removed by moving it downward. Therefore, the fixed lamp of the utility model can be quickly installed and disassembled, and because the position of the lamp body can be adjusted after installation, when the shape of the lamp body is square, the initial installation position requirements of the mounting plate can be reduced.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Embodiment 1: Figure 1 As shown, a fixed lamp that can be quickly installed and disassembled includes a mounting plate 1 and a lamp body 2, four disassembly and assembly mechanisms 3 are evenly spaced along a circle around the mounting plate 1, and two elastic telescopic mechanisms 4 are evenly spaced along a circle are provided on the lamp body 2, the two elastic telescopic mechanisms 4 can correspond one-to-one with two of the four disassembly and assembly mechanisms 3, and each elastic telescopic mechanism 4 can first shrink and move from the bottom to the top of a corresponding disassembly and assembly mechanism 3, and then stretch to be supported by the disassembly and assembly mechanism 3.

[0022] When the cam 2 is in the closed position, the two elastic retractable mechanisms 4 are in the initial state, and the two elastic retractable mechanisms 4 correspond to the two disassembly and assembly mechanisms 3 one by one. In a corresponding elastic retractable mechanism 4 and a disassembly and assembly mechanism 3, one end of the elastic retractable mechanism 4 extends to the bottom of the disassembly and assembly mechanism 3. At this time, the lamp body 2 is moved upward, and each elastic retractable mechanism 4 moves upward synchronously with the lamp body 2. During the upward movement of each elastic retractable mechanism 4, after contacting the corresponding disassembly and assembly mechanism 3, one end of the elastic retractable mechanism 4 will first be squeezed by the disassembly and assembly mechanism 3 and shrink to contact the outer side of the disassembly and assembly mechanism 3, and then move to separate from the outer side of the disassembly and assembly mechanism 3 and reset to stretch to be supported above the disassembly and assembly mechanism 3. At this time, if the lamp body 2 is rotated, one end of each elastic retractable mechanism 4 can be squeezed by the corresponding disassembly and assembly mechanism 3 again and shrink to contact the outer side of the disassembly and assembly mechanism 3.

[0023] When the cam 2 is in the closed position, the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 is in the closed position, and the cam The compression on the elastic telescopic mechanism 4 disappears, and the elastic telescopic mechanism 4 stretches and resets to the top of the disassembly and assembly mechanism 3. The disassembly and assembly mechanism 3 serves as a hanging part to suspend and support the lamp body 2. Because there is no other connection between the elastic telescopic mechanism 4 and the disassembly and assembly mechanism 3, the lamp body 2 and the mounting plate 1 can rotate relative to each other. At this time, the position of the lamp body 2 can be adjusted by rotating the lamp body 2. When the lamp body 2 needs to be disassembled, first rotate the lamp body 2 until one end of each elastic telescopic mechanism 4 contacts its corresponding disassembly and assembly mechanism 3, and continue to rotate the lamp body 2. At this time, each elastic telescopic mechanism 4 is squeezed by the corresponding disassembly and assembly mechanism 3 and shrinks to contact the outer side of the disassembly and assembly mechanism 3. After that, the lamp body 2 can be removed by moving the lamp body 2 downward. Therefore, the fixed lamp of the utility model can be quickly installed and disassembled, and because the position of the lamp body 2 can be adjusted after installation, when the shape of the lamp body 2 is square, the initial installation position requirement of the mounting plate 1 can be reduced.

[0024] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that: Figures 2 to 4As shown, in this embodiment, each disassembly and assembly mechanism 3 includes an arc-shaped plate 31 and two first guide ribs 32, the inner arc surface of the arc-shaped plate 31 is fixed to the outer side surface of the mounting plate 1, and the two are in a fitted state, the two first guide ribs 32 are arranged on the arc-shaped plate 31 at intervals on the left and right, and the bottoms of the two first guide ribs 32 are fixed on the arc-shaped plate 31, the inner side surface of each first guide rib 32 is an arc-shaped surface, the inner side surface of each first guide rib 32 is fixed to the outer side surface of the mounting plate 1, and the two are in a fitted state, the opposite side of the two first guide ribs 32 is its disassembly guide surface, the disassembly guide surface of each first guide rib 32 is an inclined surface, and the distance between the disassembly guide surfaces of the two first guide ribs 32 increases from the inside to the outside; each elastic telescopic mechanism 4 includes a mounting seat 41, a spring and a guide portion 42, and the mounting seat 41 is fixed to the lamp body 2 A moving channel with an opening at one end is provided in the mounting seat 41, and one end of the guide portion 42 has four end faces, the upper end face of one end of the guide portion 42 is its installation guide face, the left end face and the right end face are its disassembly guide faces, and the lower end face is a plane. The installation guide face and the two disassembly guide faces of the guide portion 42 are both inclined faces. The spring is located in the moving channel, and the other end of the guide portion 42 is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the mounting seat 41. The guide portion 42 can compress or stretch the spring when subjected to force and move along the moving channel; the installation guide face of the guide portion 42 is used to cooperate with the bottom of the arc-shaped plate 31 of the disassembly and assembly mechanism 3 to squeeze the spring to make the spring contract, and the two disassembly guide faces of the guide portion 42 are used to match the disassembly guide faces of the two first guide ribs 32 of the disassembly and assembly mechanism 3 one by one to squeeze the spring to make the spring contract.

[0025] In this embodiment, when the lamp body 2 is located below the mounting plate 1 and the two are aligned up and down, the two elastic telescopic mechanisms 4 correspond to the two disassembly mechanisms 3 one by one, and in the corresponding elastic telescopic mechanism 4 and one disassembly mechanism 3, the installation guide surface of the guide part 42 of the elastic telescopic mechanism 4 extends to the bottom of the arc plate 31 of the disassembly mechanism 3, and then the lamp body 2 is moved upward, and each elastic telescopic mechanism 4 moves upward synchronously with the lamp body 2. During the upward movement, one end of each elastic telescopic mechanism 4 is blocked by the disassembly mechanism 3 after contacting its corresponding disassembly mechanism 3. During the continued movement, the installation guide surface of the guide part 42 contacts the bottom of the arc plate 31 of the disassembly mechanism 3 and is squeezed by the bottom of the arc plate 31. The guide part 42 begins to squeeze the spring connected to it to shrink the spring. During the spring shrinkage process, the spring drives the guide part 42 to move. When the guide part 42 moves to contact the outer side of the arc plate 31 of the disassembly mechanism 3, the guide part 42 leaves the bottom of the arc plate 31 at this time. The elastic telescopic mechanism 4 is pressed against the outer side of the arc plate 31 and receives the extrusion force from the outer side of the arc plate 31. Then, the elastic telescopic mechanism 4 continues to move upward. When the guide part 42 moves to separate from the outer side of the arc plate 31, the extrusion force of the arc plate 31 on the guide part 42 disappears. At this time, the spring rebounds and stretches to reset, pushing the guide part 42 above the arc plate 31. At this time, the arc plate 31 serves as a suspension member to suspend and support the lamp body 2. The guide part 42 can rotate along the arc plate 31. When it is necessary to disassemble the lamp, When removing the lamp body 2, first rotate the lamp body 2 until a disassembly guide surface of the guide portion 42 of each elastic telescopic mechanism 4 contacts with a disassembly guide surface of a first guide rib 32 of the corresponding disassembly and assembly mechanism 3, and continue to rotate the lamp body 2. At this time, the guide portion 42 of each elastic telescopic mechanism 4 is squeezed by the first guide rib 32 contacting it, and the spring connected to the guide portion 42 contracts until it contacts with the outer side of the guide portion 42 and the first guide rib 32. After that, move the lamp body 2 downward to remove the lamp body 2.

[0026] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that: Figures 5 to 10 As shown, in this embodiment, an electric kettle type coupler male plug 5 is arranged at the center of the lamp body 2, and the electric kettle type coupler male plug 5 is connected to the power line of the lamp body 2. A through hole running through the upper and lower parts is arranged at the center of the mounting plate 1, and a wiring terminal 6 and an electric kettle type coupler female plug 7 are arranged at the through hole. The wiring terminal 6 is located above the electric kettle type coupler female plug 7, and is connected to the electric kettle type coupler female plug 7 through a metal spring 8. The wiring terminal 6 is used to plug in an external power line.

[0027] In this embodiment, when installing the mounting plate 1, the external power cord can be directly plugged into the wiring terminal 6, and then the center of the lamp body 2 and the mounting plate 1 are aligned. When the lamp body 2 is installed on the mounting plate 1, the electric kettle type coupler male plug 5 and the electric kettle type coupler female plug 7 are plugged together, thereby connecting the external power cord with the power cord of the lamp body 2. This avoids the problem in the prior art that when installing the lamp body 2, the power cord of the lamp body 2 and the external power cord need to be additionally connected through the wiring terminal 6 or directly connected and then insulated, and then the power cord of the lamp body 2 and the external power cord need to be arranged to avoid interfering with the subsequent fixation of the lamp body 2 and the mounting plate 1, resulting in a complicated installation process and low efficiency.

[0028] Embodiment 4: This embodiment is basically the same as Embodiment 3, with the difference being that in this embodiment, a fixed lamp capable of rapid installation and disassembly further comprises a plurality of guide mechanisms 9 evenly spaced along a circle, each guide mechanism 9 comprising two second guide ribs 91, the two second guide ribs 91 being spaced apart and fixed on the lamp body 2, each second guide rib 91 having a guide surface, and the guide surface being composed of an inclined surface and a vertical plane.

[0029] In this embodiment, when the installation guide surface of each elastic telescopic mechanism 4 extends to the bottom of the arc plate 31 of the disassembly mechanism 3 corresponding thereto, the guide surface of each second guide rib 91 is also located below the arc plate 31 of a disassembly mechanism 3. During the upward movement of the lamp body 2, the inclined surface of the guide surface of each second guide rib 91 first contacts the bottom of the arc plate 31 and moves upward. When the guide portion 42 of each elastic telescopic mechanism 4 moves to contact the outer side of the arc plate 31 of the corresponding disassembly mechanism 3, the vertical plane of the guide surface of each second guide rib 91 also contacts the arc plate 31. 1, during the upward movement of the lamp body 2, the guide surface of the second guide rib 91 maintains contact with the arc plate 31, thereby avoiding jamming caused by twisting of the spring and at the same time keeping the electric kettle type coupler male plug 5 and the electric kettle type coupler female plug 7 coaxial, ensuring the smooth progress of the installation process. Similarly, during the disassembly of the lamp body 2, the guide surface of the second guide rib 91 maintains contact with the arc plate 31, thereby avoiding jamming caused by twisting of the spring and jamming caused by eccentricity of the electric kettle type coupler male plug 5 and the electric kettle type coupler female plug 7.
