[0002] As one of the more popular lamps nowadays, ceiling lamps are deeply loved by consumers for their energy saving, practicality and simplicity. They are mostly used in homes, offices and other places. However, when installing ceiling lamps, it is necessary to first remove the light cover, pass the bolts through the lamp back plate and fix them with the connecting seat, and then install the light cover after the connection is completed. Such a ceiling lamp structure has the following defects: due to the obstruction of the lamp back plate during installation, it is difficult for people to align the screw holes of the connecting seat when installing the ceiling lamp. During installation, it is necessary to hold the ceiling lamp with one hand and tighten the bolts with the other hand. After tightening the bolts, the light cover must be installed; when disassembling, it is also necessary to remove the light cover first and then unscrew the bolts. When the ceiling is at a high position, it is difficult for people to operate on a ladder, which makes the installation and disassembly of the ceiling lamp very inconvenient and there are safety hazards.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the accompanying drawings, the utility model is a ceiling lamp that is easy to assemble and disassemble, including a mounting base 1 fixedly mounted on the ceiling and a lamp body 2. Figure 1-3As shown, the mounting base 1 is provided with an arc slot 3, and the arc slot 3 includes a first arc segment 31 and a second arc segment 32 which are connected to each other, and the width of the first arc segment 31 is greater than the width of the second arc segment 32. A positioning member 4 slidably connected to the arc slot 3 is provided on the back of the lamp body 2, and an anti-detachment cover plate 40 with a diameter greater than the width of the second arc segment 32 is provided on the top of the positioning member 4. The mounting base 1 also includes an access section located between the first arc segment 31 and the second arc segment 32, and the two side walls of the access section are inclined from the first arc segment 31 to the second arc segment 32, which is conducive to the positioning member 4 to slide into the second arc segment 32 along the first arc segment 31. The anti-detachment cover plate 40 is smaller than the groove width of the first arc segment 31 and larger than the groove width of the second arc segment 32. The area of ​​the first arc segment 31 can be set larger to facilitate the entry of the positioning member 4.

[0020] The utility model discloses a ceiling lamp which is easy to assemble and disassemble. By arranging an arc slot hole 3 on the mounting base 1 and cooperating with a portable structure of a positioning piece 4 arranged on the lamp body 2, the mounting base 1 is first installed, and then the entire lamp body 2 is covered on the mounting base 1, and the positioning piece 4 enters the arc slot hole 3, so that the anti-detachment cover plate 40 passes through the first arc segment 31, and after entering, the lamp body 2 is rotated to make the positioning piece 4 slide along the first arc segment 31 to the second arc segment 32, and continue to rotate until the positioning piece 4 is against the end of the second arc segment 32 away from the first arc segment 31, and the installation is completed. The lamp body 2 is pressed downward due to gravity, so that the anti-detachment cover plate 40 is pressed on the mounting base 1 to fix the ceiling lamp. For disassembly, it is only necessary to rotate the lamp body 2 in the opposite direction to make the positioning piece 4 enter the first arc segment 31 again. The rotation method is used instead of the traditional bolt fixing method, which is convenient for the assembly and disassembly of the ceiling lamp. The overall structure is simple, and the cumbersome operations of people at high altitudes are reduced, thereby reducing safety hazards.

[0021] In this embodiment, the mounting base 1 is provided with a protruding connecting shell 11, and the protruding height of the connecting shell 11 is greater than the thickness of the anti-detachment cover plate 40. The mounting base 1 protrudes the connecting shell 11 upward, and a connecting hole is provided on the connecting shell 11 for connecting to the ceiling. Since the anti-detachment cover plate 40 needs to pass through the arc slot hole 3 to enter the top of the mounting base 1, a protruding connecting shell 11 is provided, and a certain space needs to be reserved for the mounting base 1 for the anti-detachment cover plate 40 to enter and exit.

[0022] In this embodiment, one side wall of the second arc segment 32 is provided with a protrusion 300 for resisting the positioning member 4. The protrusion 300 can be provided on the inner circular side wall or the outer circular side wall of the second arc segment 32, or on both side walls. The straight-line distance from the protrusion 300 to the other side wall is slightly smaller than the diameter of the positioning member 4, approximately less than 1 mm. If it is set too small, it will affect the passage of the positioning member 4. The protrusion 300 is used to clamp the positioning member 4. When the positioning member 4 slides to the protrusion 300, it only needs to continue to rotate the lamp body 2 with a little force, so that the positioning member 4 passes through the protrusion 300 and comes to one end of the second arc segment 32. At this time, the positioning member 4 is restricted in the second arc segment 32 by the obstruction of the protrusion 300, so that the lamp body 2 is fixedly installed.

[0023] In this embodiment, the lamp body 2 includes a back plate 21 and a light-transmitting cover 22 . The light-transmitting cover 22 is fixedly connected to the back plate 21 . The positioning member 4 is disposed on the back plate 21 . Electrical components 200 such as a light source board are also disposed in the lamp body 2 .

[0024] In this embodiment, the back plate 21 is recessed with an annular groove 210, and the mounting base 1 is protruded with a ring 101 matching the annular groove 210 on the side facing the back plate 21. The ring 101 rotates in the annular groove 210. This structure facilitates the positioning of the back plate 21 and the mounting base 1, and at the same time prevents the lamp body 2 from shifting during rotation. The center of the annular groove 210 is the same as the center of the arc slot hole 3, which is beneficial to the sliding of the positioning member 4 and the arc slot hole 3.

[0025] In this embodiment, the back plate 21 is provided with a through hole 221, and the light cover 22 is provided with a screw hole 222. The back plate 21 is provided with a through hole 221, and is connected to the screw hole 222 by a bolt passing through the through hole 221, that is, the bolt enters from the back plate 21 and is connected to the light cover 22. The connecting parts are not visible from the front of the light cover 22, so the surface of the light cover 22 is kept neat. The lamp body 2 is formed into a whole through the fixed connection between the back plate 21 and the light cover 22 and then installed on the ceiling, without the need for people to hold extra objects in their hands at high altitudes.

[0026] In this embodiment, the arc slot holes 3 are provided with two or more, and the number of the positioning members 4 is the same as that of the arc slot holes 3. Figure 2-3 As shown, there are two or four of them, and they are symmetrically arranged in pairs, so that the connection between the ceiling lamp and the mounting base 1 is more stable. The specific size depends on the size of the ceiling lamp. Figure 2 The specifications shown are small and light, and two arc slots 3 and positioning members 4 can be set, such as ceiling lamps. Figure 3 If the size shown is larger and the weight is heavier, four arc slots 3 and four positioning members 4 can be provided to improve the installation stability of the ceiling lamp.

[0027] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
