[0116] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0117] like Figures 1 to 3 As shown, this embodiment provides a ceiling lamp installation structure 100 , including a lamp holder 10 , an elastic structure 20 , a mounting seat 30 , and a limiting member 40 .

[0118] The lamp holder 10 is used to install the lamp 60 , and the lamp holder 10 is provided with a connecting portion 11 . The elastic structure 20 is elastically connected to the outer peripheral surface of the connecting portion 11 , and the elastic structure 20 can be close to or away from the connecting portion 11 .

[0119] The top of the mounting base 30 is used to be fixed to a wall or a ceiling in the room, and the mounting base 30 is fixed by fasteners such as screws, including but not limited to countersunk screws or expansion screws, etc. The lamp holder 10 is detachably connected to the bottom of the mounting base 30 .

[0120] The bottom end surface of the mounting seat 30 is provided with a mounting groove 34, and the connecting portion 11 is rotatably received in the mounting groove 34. A limiting member 40 is provided on the inner circumference of the mounting groove 34, and a limiting groove 41 is provided on the side of the limiting member 40 away from the mounting groove 34. The limiting groove 41 is used to receive and limit the elastic structure 20, so that when the elastic structure 20 is received in the limiting groove 41, the elastic structure 20 is limited to the mounting seat 30, thereby realizing the connection between the lamp holder 10 and the mounting seat 30. Along the rotation direction R of the connecting portion 11, the two opposite ends of the limiting member 40 are provided with guide structures 401, and the guide structures 401 are used to abut against the elastic structure 20 to guide the elastic structure 20 to enter or leave the mounting groove 34.

[0121] In this way, in the ceiling lamp installation structure 100 of the present application, when the connecting part 11 of the lamp holder 10 rotates relative to the mounting seat 30, the elastic structure 20 rotates with the connecting part 11 to the limit member 40, and the guide structure 401 supports the elastic structure 20 so that the elastic structure 20 moves toward the connecting part 11 until it can smoothly enter or leave the mounting groove 34, so that when the elastic structure 20 continues to rotate with the connecting part 11, the elastic structure 20 enters or leaves the mounting groove 34, thereby realizing the assembly or disassembly of the lamp holder 10 and the mounting seat 30, and the assembly and disassembly operations only need to be completed by rotating the lamp holder 10, thereby greatly improving the disassembly efficiency of the lamp holder 10 and the mounting seat 30.

[0122] Please combine again Figures 2 to 4 In one embodiment, the shape of the lamp holder 10 is circular or rectangular. An end surface of the lamp holder 10 close to the mounting base 30 is provided with an empty groove 12, and the shape of the empty groove 12 is circular. The connecting portion 11 is protruded from the bottom wall of the empty groove 12, and the protruding height of the connecting portion 11 is less than the groove depth of the empty groove 12. The connecting portion 11 is a cylindrical structure and is coaxially arranged with the lamp holder 10. The outer circumference of the connecting portion 11 is spaced from the inner circumference of the empty groove 12, so that an active cavity 13 is formed between the two.

[0123] The mounting seat 30 includes a top plate 31 and a side plate 32. The top plate 31 is circular in shape and is coaxially arranged with the connecting portion 11. The side plate 32 surrounds and is connected to the outer peripheral surface of the top plate 31, and a mounting groove 34 is formed by the side plate 32 and the top plate 31. The connecting portion 11 rotates around the central axis of the top plate 31 in the mounting groove 34. The bottom end of the side plate 32 is rotatably received in the movable cavity 13.

[0124] Furthermore, the elastic structure 20 includes an elastic member 22 and a clamping member 21, and the elastic member 22 is a compression spring or the like. A slide groove 111 is provided on the outer peripheral surface of the connecting portion 11, and the extension direction of the slide groove 111 is parallel to the radial direction of the connecting portion 11. The clamping member 21 is partially slidably accommodated in the slide groove 111, and the elastic member 22 is elastically connected between the clamping member 21 and the bottom wall of the slide groove 111, and is used to apply an elastic force to the clamping member 21 away from the connecting portion 11. When the elastic structure 20 is not supported by the guide structure 401 or the like, one end of the clamping member 21 extends out of the slide groove 111 and is located in the active cavity 13, so that the end of the clamping member 21 extending into the active cavity 13 can be supported by the limiting member 40.

[0125] It is understandable that the number of the elastic structures 20 may be multiple, for example, three or more, and the number of the stoppers 40 is the same as the number of the elastic structures 20. The multiple elastic structures 20 are arranged around the outer circumference of the connecting portion 11 at equal intervals.

[0126] Please combine again Figures 2 to 4In one embodiment, the stopper 40 is roughly arc-shaped, and one side surface of the stopper 40 is attached to the inner surface of the side plate 32. A connecting plate 43 is integrally formed at the top of the stopper 40, and the connecting plate 43 is attached to the top plate 31. The connecting plate 43 has a first connecting hole 430, and the top plate 31 has a second connecting hole 310. The first connecting hole 430 and the second connecting hole 310 are used for fasteners such as screws to pass through, so as to fix the connecting plate 43 to the top plate 31.

[0127] Furthermore, the guide structure 401 includes two guide portions 42 connected to opposite ends of the stopper 40 along the rotation direction R of the connection portion 11 . One end of the guide portion 42 is integrally formed with the stopper 40 , and the other end of the guide portion 42 abuts against the side plate 32 .

[0128] The surface of the guide portion 42 on the side away from the side plate 32 is set as a first guide surface P1, and the first guide surface P1 extends obliquely from its end close to the limiting member 40 toward the side of the inner circumferential surface close to the mounting groove 34. The first guide surface P1 is used to press the clamping member 21 to slide toward the connecting portion 11, and in the process of the clamping member 21 sliding toward the connecting portion 11, the elastic member 22 is continuously compressed, so that when the first guide surface P1 no longer presses the clamping member 21, the elastic member 22 is reset and drives the clamping member 21 to slide in the direction away from the connecting portion 11, thereby allowing the clamping member 21 to extend into the limiting groove 41.

[0129] Furthermore, the guiding structure 401 further includes two second guiding surfaces P2 . Along the rotation direction R of the connecting portion 11 , inner walls on opposite sides of the limiting groove 41 are configured as the two second guiding surfaces P2 .

[0130] One end of the second guide surface P2 is connected to one end of the first guide surface P1, and the connection between the second guide surface P2 and the first guide surface P1 is smoothly transitioned. The second guide surface P2 extends obliquely from its end close to the first guide surface P1 toward one side of the inner circumference close to the mounting groove 34, and the second guide surface P2 is used to support the elastic structure 20 close to the connecting portion 11. The second guide surface P2 is arranged at an angle with the first guide surface P1, and the angle is an acute angle.

[0131] In this way, when the clamping member 21 received in the limiting groove 41 is about to leave the limiting groove 41, the second guide surface P2 presses against the clamping member 21, so that the clamping member 21 slides toward the connecting portion 11, so that the clamping member 21 is no longer restricted by the second guide surface P2 and leaves the limiting groove 41. In addition, when the clamping member 21 slides toward the connecting portion 11, the elastic member 22 is continuously compressed, so that when the second guide surface P2 no longer presses against the clamping member 21, the elastic member 22 is reset and drives the clamping member 21 to slide in a direction away from the connecting portion 11.

[0132] In addition, when the clamping member 21 is received in the limiting groove 41 , along the rotation direction R of the connecting portion 11 , the two opposite ends of the clamping member 21 respectively abut against the two second guide surfaces P2 , thereby limiting the clamping member 21 in the rotation direction R of the connecting portion 11 .

[0133] Please combine again Figures 2 to 4 In one embodiment, a support protrusion 33 is provided around the inner circumference of the mounting groove 34 . The support protrusion 33 is integrally formed with the side plate 32 , and the support protrusion 33 is located at one end of the side plate 32 away from the top plate 31 .

[0134] The support protrusion 33 is substantially parallel to the top plate 31 , and the support protrusion 33 and the top plate 31 are spaced apart from each other, so that an installation gap 35 is formed between the support protrusion 33 and the top plate 31 , and the stopper 40 is received in the installation gap 35 .

[0135] In particular, one end of the limiting groove 41 away from the connecting portion 11 passes through the limiting member 40, so that the bottom end surface of the limiting member 40 received in the limiting groove 41 can contact the supporting protrusion 33. When the clamping member 21 is received in the limiting groove 41, the supporting protrusion 33 abuts against the clamping member 21, so that the clamping member 21 is supported by the supporting protrusion 33.

[0136] In addition, the support protrusion 33 is provided with a plurality of openings 330, and the openings 330 penetrate the support protrusion 33 along the extension direction of the side plate 32. The number of the openings 330 is the same as the number of the limiting members 40, so that each opening 330 can allow a clamping member 21 to enter the installation gap 35 from the opening 330, so that the clamping member 21 can subsequently enter the limiting groove 41 of the limiting member 40.

[0137] like Figure 5 and Figure 6 As shown, the present application also provides a ceiling lamp 200, including a lamp 60, a power connection assembly 70, and the above-mentioned ceiling lamp mounting structure 100. The lamp 60 is mounted on an end of the lamp holder 10 away from the mounting base 30, and the connection method between the lamp 60 and the lamp holder 10 includes but is not limited to a snap connection, a glue connection, or a threaded connection.

[0138] The mounting base 30 is provided with a receiving groove 311, which extends downward from the end surface of the mounting base 30 away from the lamp holder 10 to penetrate the mounting base 30. The power connection assembly 70 is received in the receiving groove 311 and is detachably connected to the mounting base 30. The lamp 60 is electrically connected to the power connection assembly 70, and the power connection assembly 70 is electrically connected to the external power grid through the connection wire, so that the external power grid supplies power to the lamp 60.

[0139] Please combine again Figures 7 to 10 In one embodiment, the power connection assembly 70 includes a power connection socket 71 , a power connection cover 72 , a first conductive member 73 , a second conductive member 74 , and a switching member 75 .

[0140] The power socket 71 is installed in the receiving groove 311, and the outer circumference of the power socket 71 is against the inner circumference of the receiving groove 311. The power socket 71 can be connected to the mounting base 30 by screws or bolts.

[0141] The power connection cover 72 is covered on the top surface of the power connection seat 71, and after the power connection cover 72 and the power connection seat 71 are connected, the two are surrounded by a power connection cavity, and the power connection cover 72 and the power connection seat 71 are both made of insulating materials such as plastic. The power connection cover 72 and the power connection seat 71 can be connected by components such as screws or bolts. The first conductive member 73 and the second conductive member 74 are both made of conductive materials and are both located in the power connection cavity. The connection between the power connection cover 72 and the power connection seat 71 is sealed to protect the first conductive member 73 and the second conductive member 74 located in the power connection cavity.

[0142] Please combine again Figures 7 to 10 In one embodiment, the first conductive member 73 is mounted on the power socket 71 and is used to be electrically connected to the lamp 60. The top surface of the power socket 71 is convexly provided with a first boss 711 and a second boss 712, and the first boss 711 and the second boss 712 are arranged at intervals. The first boss 711 is a cylindrical structure, and the second boss 712 is an annular structure, and the second boss 712 is surrounded to form a first receiving cavity 7121.

[0143] The first conductive member 73 includes a first section 731, a second section 732, and a third section 733 connected in sequence. The first section 731 is bent and roughly U-shaped. One end of the first section 731 is abutted against the first boss 711, and the other end is connected to the second section 732. The second section 732 is flat on the first boss 711, and the second section 732 is provided with a limiting hole 7320. The first boss 711 is convexly provided with a limiting column 7110, and the limiting column 7110 is clamped in the limiting hole 7320. The third section 733 is received in the first receiving cavity 7121.

[0144] It is worth noting that there are three first conductive members 73 for connecting the neutral line, the live line, and the ground line respectively. The three first conductive members 73 are arranged in parallel and spaced apart from each other, and the first conductive member 73 for connecting the ground line is located in the middle.

[0145] The first boss 711 is provided with a first through hole 7111, a second through hole 7112 and a third through hole 7113. The second through hole 7112 is located between the first through hole 7111 and the third through hole 7113. The distance between the first through hole 7111 and the second through hole 7112 is smaller than the distance between the third through hole 7113 and the second through hole 7112. One end of the first section 731 of the first conductive member 73 for grounding is inserted into the second through hole 7112, and one end of the first sections 731 of the other two first conductive members 73 are inserted into the first through hole 7111 and the third through hole 7113 respectively.

[0146] The bottom end surface of the power socket 71 is convexly provided with a first mounting platform 715, a second mounting platform 716, and a third mounting platform 717. The first mounting platform 715, the second mounting platform 716, and the third mounting platform 717 are all annular and coaxially arranged. The second mounting platform 716 is arranged around the outer periphery of the first mounting platform 715 at intervals, and the third mounting platform 717 is arranged around the outer periphery of the second mounting platform 716 at intervals.

[0147] The electrical connection assembly 70 further includes a conductive column 781, a first conductive ring 783, and a second conductive ring 784. The conductive column 781 is installed in the cavity formed by the first mounting platform 715, and the cavity is connected to the second through hole 7112, so that the first conductive member 73 extending into the second through hole 7112 contacts the conductive column 781 to form a current channel. The first conductive ring 783 is a circular ring structure, and is installed in the cavity between the first mounting platform 715 and the second mounting platform 716, and the cavity is connected to the first through hole 7111, so that the first conductive member 73 extending into the first through hole 7111 contacts the first conductive ring 783 to form a current channel. The second conductive ring 784 is a circular ring structure, and is installed in the cavity between the third mounting platform 717 and the second mounting platform 716, and the cavity is connected to the third through hole 7113, so that the first conductive member 73 extending into the third through hole 7113 contacts the second conductive ring 784 to form a current channel.

[0161] Please combine again Figures 8 to 10 In one embodiment, the switching member 75 is slidably connected to the power receiving socket 71, one end of the switching member 75 is exposed in the power receiving cavity, and the other end of the switching member 75 is located in the power receiving cavity and movably abuts against the second conductive member 74 to adjust the size of the wire pressing cavity 79 through the switching member 75.

[0162] Specifically, the switching member 75 is a cylindrical structure, and the power socket 71 is provided with a sliding groove 714, the extension direction of the sliding groove 714 is parallel to the axial direction of the power socket 71, and penetrates the power socket 71. The switching member 75 can be slidably accommodated in the sliding groove 714, and the bottom end of the switching member 75 is exposed in the sliding groove 714, so as to facilitate pressing the switching member 75.

The two wedge-shaped portions 751 are used to abut the second conductive member 74, so that when the switching member 75 slides upward, the wedge-shaped portion 751 abuts the second conductive member 74 to move upward and move it away from the first conductive member 73, thereby increasing the size of the wire pressing cavity 79, and the connecting wire can smoothly enter or leave the wire pressing cavity 79, and in this process, the second conductive member 74 is gradually compressed. When the switching member 75 slides downward or the external force driving the switching member 75 to slide upward is removed, the second conductive member 74 approaches the first conductive member 73 under the action of its own elastic reset, thereby reducing the size of the wire pressing cavity 79 and clamping the connecting wire between the first conductive member 73 and the second conductive member 74.

[0164] In particular, a retaining protrusion 752 is provided on the outer surface of the section of the switching member 75 located in the first receiving cavity 7121, and a retaining groove 7122 is provided on the inner wall of the first receiving cavity 7121.
