When it is necessary to install the lamp on a base such as a roof or a ceiling, the operator only needs to push up the connecting base 2 so that the second receiving cavity 2B of the second main body part 2A of the connecting base 2 accommodates the first body of the fixing base 1 part 1A, and then only by axially rotating the connection seat 2, the mechanical connection between the first joint part of the fixed seat 1 and the second joint part of the connection seat 2 and the connection between the first electrical connection part and the connection of the fixed seat 1 can be realized at the same time. The electrical connection between the second electrical connection parts of the seat 2, and then realize the mechanical connection and electrical connection of the lamp. Wherein, the term "axial direction" used in the preferred embodiment of the present invention refers to the axial direction of the fixing seat 1 . The term "pushing up" used in the preferred embodiment of the present invention refers to pushing the connecting seat 2 toward the direction close to the fixed seat 1 in the axial direction or pushing the connecting seat 2 toward the connecting seat 2 and the fixed seat in the axial direction. The relative distance between 1 is pushed in the direction of decreasing.

When disassembling the lamp, the operator only needs to push up the connecting seat 2 and then rotate the connecting seat 2 in the opposite direction, and then separate the connecting seat 2 from the fixed seat 1, so as to release the connection between the first joint part of the fixed seat 1 and the connecting seat 2 The mechanical connection between the second joint parts and the electrical connection between the first electrical connection part of the fixing base 1 and the second electrical connection part of the connection base 2 allow the lamp to be disassembled.

When the second joint part is connected, an axial force is applied to the bottom end surface of the second receiving cavity. Further, the elastic element 10 can also be arranged on the bottom end surface of the second receiving chamber of the connecting base at a position close to the second joint part (not shown), for connecting the first joint part of the fixing base with the first joint part of the connecting base. When the two joint parts are connected, an axial force is applied to the bottom end surface of the first main body part of the fixing seat. Further, the elastic element 10 may be disposed on the bottom end surface of the first main body portion of the fixing seat and the bottom end surface of the second receiving cavity of the connecting seat (not shown). Further, the elastic element 10 is a structure such as a spring or other metal shrapnel. Preferably, as shown in FIG. The pressing part 102 is fixedly connected with the elastic part 101. When the fixed seat 1 and the connecting seat 2 are connected, the elastic part 101 is pressed by the protective cover, so that the pressing part 102 of the elastic element 10 presses the connecting seat 2 downward. At this time, the elastic part 101 is in a compressed state, and an axial force is generated between the fixing seat 1 and the connecting seat 2, so as to ensure that the connecting seat will not generate any force relative to the fixing seat after the installation of the lamp is completed. Move up, down, left, and right. Further, the elastic element 10 is evenly arranged at a position close to the first joint portion with the center of the bottom end surface of the first main body 1A as the center of a circle, or at a position close to the bottom end surface of the second receiving cavity 2B of the connecting seat 2 . The center is the center of the circle and is evenly arranged at a position close to the second joint part. Further, the number of the elastic elements 10 is consistent with the number of the first joints or the second joints, and the elastic elements 10 and the first joints and the second joints are arranged in a straight line along the radial direction.

The position-limiting structure 52 of the slot 5 is installed in place, that is, the mechanical connection between the first joint portion of the fixing base 1 and the second joint portion of the connecting base 2 is completed.

Preferably, as shown in FIG. 1 , there is a height difference between the limiting structure 52 of the U-shaped installation groove 5 and the opening end 51 , and the limiting structure 52 is higher than the opening end 51 . When installing the lamp, push up the connecting seat 2, overcome the axial force of the elastic element 10 on the connecting seat 2, push the protrusion 3 of the connecting seat 2 to the position near the opening end 51 of the U-shaped installation groove 5, and then push the protrusion 3 enters from the opening end 51 of the U-shaped mounting groove 5, and rotates along the circumferential direction of the inner wall 2B of the second receiving chamber until it abuts against the inner wall of the limiting structure 52. Due to the existence of the axial force of the elastic element 10, the connecting seat 2 will move axially away from the fixed seat 1 until the top surface of the protrusion 3 of the fixed seat 1 and the inner limit structure 52 of the connecting seat 2 The top surfaces are fitted together so as to realize the mechanical connection between the first joint portion of the fixing base 1 and the second joint portion of the connection base 2 . Afterwards, between the fixed seat 1 and the connecting seat 2, since the axial force generated by the elastic element 10 always exists, and under the action of the gravity of the lamp itself, the fixed seat 1 and the connecting seat 2 are engaged with each other more firmly, There will be no shaking of the lamp up and down, left and right.

Preferably, the number of the second joints is in multiples of the number of the first joints, and the number of the second joints is not less than the number of the first joints. Specifically, the number of first joints such as projections 3 is preferably three, the number of second joints such as U-shaped mounting grooves 5 is six, and the three protrusions 3 are spaced at the same angle from each other.

By providing the hooking portion 54 , when disassembling the lamp, the operator needs to push up and then rotate the connecting seat 2 to disassemble the lamp. Specifically, when the fixing base 1 and the connecting base 2 need to be separated, the operator cannot directly separate the fixing base 1 and the connecting base 2 by rotating the connecting base 2 in reverse, because due to the existence of the hook portion 54, the hook The engaging portion 54 will prevent the protrusion 3 from directly moving out of the U-shaped installation groove 5 . At this time, the operator needs to push up the connecting seat 2 first. Since the positions of the fixed seat 1 and the bump 3 are fixed, the upward movement of the connecting seat 2 will cause the top surface of the bump 3 and the U-shaped installation groove that originally fit together The inner top surface of the limiting structure 52 of 5 is separated from each other, and the opening end 51 of the U-shaped mounting groove 5 is also moved to a position equal to the height of the bump 3, and then the connecting seat 2 is reversely rotated to realize the lamp. disassembly.
