Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present embodiment provides a lamp, as shown in fig. 1, which comprises a lamp post 1 and a lamp cap, wherein the lamp post 1 and the lamp cap can be separately transported and sold during transportation and sale, and the lamp cap and the lamp post 1 are assembled together to form the lamp during use. It should be noted that the lamp can be used as a street lamp, and can also be used for other purposes and other places of use. The upper end of the lamp post 1 can be inserted by a lamp holder so as to complete the assembly and the fixation. Referring to fig. 2, the lamp holder includes a lamp holder body 21, an expansion tube 22 and an auxiliary member 23, a threaded section 24 is provided at one end of the lamp holder body 21, the expansion tube 22 is sleeved outside the threaded section 24, the auxiliary member 23 is in threaded connection with the threaded section 24, and the expansion tube 22 is located between the lamp holder body 21 and the auxiliary member 23. It should be noted that the inner wall of the expansion tube 22 does not contact the threaded section 24, the expansion tube 22 and the lamp head body 21 are not fixed together, and the expansion tube 22 and the lamp head body 21 can move relatively. When the lamp is assembled, the threaded section 24 is inserted into the upper end of the lamp post 1, the expansion pipe 22 and the auxiliary part 23 are both located in the lamp post 1, the expansion pipe 22 is in contact with the inner wall of the lamp post 1, the lamp holder body 21 is rotated, the expansion pipe 22 and the auxiliary part 23 do not rotate, the auxiliary part 23 is close to the expansion pipe 22 under the action of the threads and moves and is inserted into the expansion pipe 22, the expansion pipe 22 expands outwards to further abut against the inner wall of the lamp post 1, and the assembly is completed and the lamp is fixed, as shown in fig. 3. When the lamp holder needs to be detached or maintained, the lamp holder body 21 is rotated reversely, the auxiliary piece 23 moves away from the expansion tube 22 under the action of the threads, the expansion tube 22 contracts and does not exert force on the inner wall of the lamp pole 1, and then the lamp holder can be pulled out. The lamp holder can be mounted and dismounted without any tool in the whole process, so that the lamp holder is dismounted without tools, the difficulty of high-altitude operation of a lamp used as a street lamp is reduced, and the risk that the tools fall from the high altitude is avoided.

In the present embodiment, as shown in fig. 1 and 2, the threaded section 24 is provided with a stopper pin 25, and the stopper pin 25 is used for limiting the auxiliary 23 from falling off the threaded section 24, so that the rotation amount does not need to be carefully taken when disassembling. In this embodiment, the expansion tube 22 is provided with the elastic sheet 221, and the auxiliary member 23 is movably inserted into the expansion tube 22 so that the elastic sheet 221 abuts against the inner wall of the lamp post 1. In this embodiment, four elastic pieces 221 are symmetrically disposed to better abut against the inner wall of the lamp post 1, so as to be more stable. In other embodiments, 2n elastic pieces 221 are symmetrically provided, where n is a positive integer, that is, the number of the elastic pieces 221 may be 2, or 6 or more. In the present embodiment, the friction fit between the expansion tube 22 and the inner wall of the lamp pole 1 is mainly that the expansion tube 22 cannot rotate easily. In other embodiments, the outer surface of the expansion tube 22 contacting the inner wall of the lamp post 1 may be designed to be square, and correspondingly, the inner wall of the lamp post 1 is also designed to be square, so as to prevent the expansion tube 22 from rotating during the process of rotating the lamp head body 21.

In this embodiment, as shown in fig. 1 and 2, the outer surface of the auxiliary member 23 is provided with a limiting rib 231, and the limiting rib 231 is caught in the gap between the adjacent spring pieces 221 on the expansion tube 22, so that when the expansion tube 22 is not rotated, the auxiliary member 23 is not rotated, but the auxiliary member 23 can move relative to the expansion tube 22. In this embodiment, the end of the auxiliary 23 close to the end of the expansion tube 22 always extends into the expansion tube 22, and before the auxiliary 23 is assembled and fixed, the end of the auxiliary 23 already extends into the expansion tube 22, so that when the auxiliary 23 moves, more parts can be inserted into the expansion tube 22 to expand the expansion tube 22 outwards to abut against the inner wall of the lamp post 1. In this embodiment, the outer diameter of the end of the auxiliary 23 close to the expansion tube 22 is gradually increased with the distance from the expansion tube 22, so that the auxiliary 23 can be better ensured to make the expansion tube 22 expand outwards to abut against the inner wall of the lamp post 1 with more parts inserted into the expansion tube 22. In this embodiment, the maximum outer diameter of the auxiliary member 23 is smaller than the inner diameter of the upper end of the lamp post 1, that is, after the threaded section 24 is inserted into the upper end of the lamp post 1, the auxiliary member 23 does not contact with the inner wall of the lamp post 1, so that the auxiliary member 23 can move linearly.

The above embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications to the above embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the present invention.
