The structure of this type of street lamp holder is relatively complicated, and it is inconvenient to assemble and install components such as LED modules, and it is also not convenient for the maintenance and replacement of street lamps; moreover, the heat dissipation fins are mainly arranged on the outside of the upper shell, which is relatively concentrated. Relatively speaking, the heat dissipation effect is not optimal. Moreover, multiple LED modules are installed in contact with the same integral heat sink at the same time, that is, an LED street lamp usually has only one integral heat sink. Although this structure is relatively simple, since all high-power LED modules are installed on the same heat sink, if one of the LED modules fails, the entire heat sink needs to be removed before the faulty LED module can be repaired. Maintenance or replacement is very cumbersome to operate, which is obviously not conducive to the maintenance and replacement of LED lamps, and also easily affects the work of other LED modules.

In addition, the existing connecting shaft and the LED lamp holder are generally hinged, and the existing hinges usually do not have a self-locking function, or the way to realize the self-locking function is complicated, the operation is cumbersome, the cost is high, the rotation is not flexible enough, and the self-locking function is not flexible enough. gender issues.

As shown in Figures 3-6, the rotary self-locking connector includes a hollow shaft sleeve 1 and a shaft 4 that matches the shaft sleeve 1. The shaft sleeve 1 is connected to the fixed mounting seat 20, and the shaft 4 is connected to the lamp holder body 30. The inner wall of the sleeve 1 is provided with a strip-shaped shaft sleeve convex tooth 2 parallel to the axis, and the surface of the rotating shaft 4 is evenly distributed with several strip-shaped rotating shaft convex teeth 5 parallel to its axis to mesh with the shaft sleeve convex teeth 2 on the inner wall of the shaft sleeve 1. It is tightly embedded in the cylindrical cavity of the shaft sleeve 1 and rotates freely and realizes self-locking due to the engagement of the convex teeth.

The sleeve 1 is preferably made of elastomer material, which has a certain elastic deformation capacity. The sleeve 1 is provided with an open groove 3 parallel to the axis of the sleeve and running through both ends of the sleeve, so that the sleeve 1 is approximately "C" when viewed from the side. When the rotating shaft 4 rotates in the inner cavity of the sleeve 1, when the convex teeth 2 and the convex teeth 5 are in contact with the tops of the teeth, the inner diameter of the sleeve 1 will be slightly increased due to the effect of pressure. The elastomer material selected by the shaft sleeve and the design of the opening groove 3 can effectively reduce the friction of the hinge mechanism during the rotation process, making its rotation more flexible.

One side of the rotating shaft 4 has a relief groove 6, one of the side walls of the relief groove 6 is the first connecting rod 7 narrower than the sleeve opening groove 3, and the other side wall of the relief groove 6 is The second connecting rod 12 which is wider than the shaft sleeve opening slot 3, the relief slot 6 is used for the shaft sleeve opening slot 3 to pass through the first connecting rod 7 and set on the rotating shaft to make space for the shaft sleeve and rotate therein. The rotating shaft 4 and the sleeve 1 are connected together through the meshing of the convex teeth. Both the rotating shaft 4 and the sleeve 1 can rotate around the axis to change the position of the convex teeth to adjust the angle and position, and use the meshing force of the convex teeth to self-lock. To realize the fixation of the angle of the fixture, no additional operation is required, the use is convenient, and the manufacturing process and cost are reduced.

Preferably, as shown in Figure 5, it is another embodiment of the present utility model, the main structure includes a shaft sleeve 1 and a rotating shaft 4, and an adapter is connected between the shaft sleeve 1 and the rotating shaft 4, as shown in Figure 5, the adapter includes The shaft sleeve 21 and the rotating shaft 24 are vertically connected to each other, the shaft sleeve 21 and the rotating shaft 24 are connected by the first connecting rod 27 and the second connecting rod 28, and there is a gap between the first connecting rod 27 and the second connecting rod 28 26.
