[0038] The working principle of the present utility model is:

[0039] As Figures 3 - 4As shown in the figure, this is a state diagram of the lamp post 2 and the connecting rod 1 before assembly. Taking the example that there are two limiting grooves 5 provided on the outer periphery of the lamp post 2, during assembly, one end of the lamp post 2 extends into the first installation cavity 4 opened in the connecting rod 1. In the initial state, one end of the positioning block 6 is located at the first end portion 51 of the limiting groove 5. Then, the lamp post 2 is rotated. The lamp post 2 drives the limiting groove 5 to rotate synchronously, and then the positioning block 6 will slide from the first end portion 51 of the limiting groove 5 to the second end portion 52. Similarly, the other positioning block 6 will also slide from the first end portion 51 to the second end portion 52 on the corresponding limiting groove 5. When the positioning blocks 6 on the connecting rod 1 all move to the second end portions 52 of the corresponding limiting grooves 5 respectively, since the second end portion 52 has a blocking effect on the positioning block 6, so when the lamp post 2 is continuously rotated in the same direction, the lamp post 2 cannot be rotated. At this time, one end of the lamp post 2 is already limited in the first installation cavity 4. In order to prevent the lamp post 2 from rotating in the opposite direction under the action of external force, at this time, the connecting rod 1 and the lamp post 2 are connected and fixed by the locking member 3. As Embodiment 1, the locking member 3 can be selected as a screw. In the above technology, the limiting groove 5 can be set to include an extension section 53 and a vertical section 54. The second end portion 52 is located at one end of the extension section 53 away from the vertical section 54, and the first end portion 51 is located at one end of the vertical section 54 away from the extension section 53.

[0040] For the lamp post fastening structure of the present application, the entire assembly process can be completed only by rotating the lamp post 2 and then using the locking member 3. The operation is simple, the connection is convenient, and it is convenient for consumers to operate. Secondly, since the first end portion 51 and the second end portion 52 on the limiting groove 5 can limit the rotation range of the lamp post 2, the rotation amplitude of the lamp post 2 is consistent each time it is installed. If there is an integral pattern on the outer parts of the lamp post 2 and the connecting rod 1, the patterns of the lamp post 2 and the connecting rod 1 can be aligned.

[0041] On the basis of the above technical solution, the present application takes a folding lamp as an example, such as Figures 2 - 3As shown, the lamp post fastening structure is applied to the lamp; as embodiment 1, a fixed sleeve 21 can be provided at the upper end of the lamp post fastening structure, and a rotating sleeve 22 can be rotatably matched on the fixed sleeve 21, and a plug-in 14 can be provided on the rotating sleeve 22. The plug-in 14 can be plugged with the bracket 13 to achieve the installation between the rotating sleeve 22 and the bracket 13, and the lower end of the connecting rod 1 is connected to the base 12. The present application has threading holes on both the fixed sleeve 21 and the rotating sleeve 22, that is, the wires on the lamp body 11 can pass through the bracket 13 through the threading holes on the rotating sleeve 22, and pass through the second installation groove 221 and the first installation groove 211 in turn, and then pass through the threading hole 220 on the fixed sleeve 21, and then the wires continue to pass through the connecting rod 1 until they are connected to the base 12, thereby realizing the hidden installation of the wires; in order to further realize the combing of the wires, a wire management shaft 7 can also be installed in the second installation cavity formed by the first installation groove 211 and the second installation groove 221, and a wire management channel 71 is provided on the wire management shaft 7, that is, when the wires are rotated, the wires can be arranged in the second installation cavity. When the threading hole on the sleeve 22 enters the second installation cavity, the wires will pass through the wire management channel 71 and then through the threading hole on the fixed sleeve 21; the above-mentioned wire management shaft 7 can realize the combing of the wires to prevent the wires from being entangled when the rotating sleeve 22 rotates; the specific installation method of the wire management shaft 7 is that a fixed plate 8 can be fixed at one end of the wire management shaft 7, and a movable plate 9 can be rotatably arranged at the other end, the fixed plate 8 can be fixed in the first installation groove 211 by bolts, and the movable plate 9 can be fixed in the second installation groove 221 by bolts; according to this arrangement, when the rotating sleeve 22 rotates relative to the fixed sleeve 21, the movable plate 9 can be driven to rotate along the outer periphery of the wire management shaft 7. In the above technology, in order to make the overall appearance more beautiful, a decorative cover 10 is provided on the relatively opposite side of the rotating sleeve 22 and the fixed sleeve 21, and the decorative cover 10 is used to cover the components in the rotating sleeve 22 and the fixed sleeve 21.

Figure 4 As shown, a wire management shaft 7, a fixed sheet 8, a movable sheet 9 and other structures may be provided between the fixed sleeve 21 and the rotating sleeve 22. Figure 5 is a schematic diagram of the assembly between the fixed sleeve 21, the rotating sleeve 22, and the cable management shaft 7; in the embodiment 2 of the present application, the fixed sleeve 21 and the rotating sleeve 22 on the lamp pole fastening structure can refer to Figure 5 As shown, a wire management shaft 7, a fixing plate 8 and other structures are arranged between the fixing sleeve 21 and the rotating sleeve 22, so that the wire management effect is better.
