[0036] In the description of the present invention, unless otherwise specified, the terms "inside", "side", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] like Figure 1-6 As shown, the utility model provides a snap-on lamp holder that can be assembled flexibly, comprising:

[0038] The lamp holder body 1 has an inner cavity provided with an elastic conductive sheet 11 for connecting the power line 3. The conductive sheet 11 is installed in the slot of the lamp holder body 1 and is tightened by a compression spring 12;

[0039] The rear cover 2 includes an outlet 21 for leading out the power cord 3;

[0040] The mica sheet 4 is fixedly mounted on the lamp holder body 1 by hollow rivets 5; the outer end of the power line 3 passes through the side of the mica sheet 4 and is led out through the outlet 21;

[0041] Elastic buckles 22 are respectively provided on both sides of the back cover 2, and the elastic buckles 22 are integrally formed with the back cover 2 and extend toward the lamp holder body 1; the lamp holder body 1 is provided with a snap-fitting buckle position 13 corresponding to the elastic buckle 22; the back cover 2 is deformed and snap-fitted and limited on the snap-fitting buckle position 13 by the elastic buckle 22, so as to be fastened and assembled with the lamp holder body 1; a guide limiting column 23 is provided in the inner cavity of the back cover 2, and the guide limiting column 23 is inserted into the inner hole of the hollow rivet 5.

[0042] The utility model improves the assembly structure of the lamp holder. By arranging an elastic buckle 22 on the back cover 2, which is reversely buckled and connected with the limit hook 14 of the snap-fit ​​buckle position 13 on the lamp holder body 1, the lamp holder can be quickly assembled. The advantage of this design is that the lamp holder can be flexibly selected for shipping. The power cord 3 and the lamp holder body 1 can be assembled first, and then the back cover 2 and other accessories such as the lamp cup can be assembled before use. The utility model can also choose to assemble the assembled power cord 3, the lamp holder body 1 and the back cover 2. Different packaging and shipping requirements are given more convenience, more choices are provided, the restrictions on assembly methods are greatly reduced, and production efficiency is improved.

[0043] At the same time, the utility model adopts a snap-on connection, and no special tools are required for assembly, which reduces the technical difficulty of assembly and reduces labor costs; at the same time, the connection is made through the elastic snap 22, so that the assembly of the two is tighter and the stability of the connection is ensured.

[0044] In this embodiment, the elastic buckle 22 is disposed on the back cover 2 . In other optional embodiments, the elastic buckle 22 may also be disposed on the lamp holder body 1 .

[0045] In this embodiment, the structure of the hollow rivet 5 for fixing the mica sheet 4 and the lamp holder body 1 is combined with the design of the guide limit column 23, so that the guide limit column 23 not only plays a guiding role but also provides additional support for the lamp holder, thus killing two birds with one stone.

[0046] In further details, the outer wall of the lamp holder body 1 is radially concave to form the snap-fit ​​buckle position 13, and a limit hook 14 is extended outward from the snap-fit ​​buckle position 13, and the limit hook 14 is reversely buckled with the elastic buckle 22. The design of the limit hook 14 and the elastic buckle 22 connected in reverse buckle makes it difficult for the elastic buckle 22 to loosen after assembly, thereby improving the assembly stability; at the same time, in order to facilitate the connection between the two, the limit hook 14 is provided with a guide slope 141 that facilitates the elastic buckle 22 to enter the snap-fit ​​buckle position 13; the elastic buckle 22 is provided with a guide slope 221 that matches the guide slope 141.
