The lighting unit 123 is arranged on the lower surface of the housing 121 . When the rotating rod 111 is rotated, the illumination unit 123 on the lower surface of the casing 121 can change the illumination angle, thus playing an angle adjustment function and providing convenience for use.

Advantageously, in an embodiment of the present invention, the pivot mechanism 13 includes a first end cover 131 , a second end cover 132 , a shaft 133 and an elastic member 135 .

Specifically, the first end cover 131 is fixed on the one end of the pivoting rod 111 . The second end cover 132 is fixed on the upper end of the support rod 112 . For example, in the example shown in FIG. 5 , the first end cover 131 and the second end cover 132 are respectively fixed to the one end of the pivoting rod 111 and the upper end of the supporting rod 112 by screws.

The shaft rod 133 is arranged coaxially with the pivot rod 111 and the support rod 112 and has a positioning section 1331 and a threaded section 1332. The first end cover 131 is circumferentially fixed to the positioning section 1331, and the second end cover 132 is pivotably connected to the positioning section 1331 . That is, the first end cover 131 and the shaft 133 are relatively fixed and can rotate synchronously, and the first end cover 131 is fixed with the pivot rod 111 , therefore, the pivot rod 111 can rotate synchronously with the shaft 133 . The second end cover 132 and the positioning section 1331 can rotate along the axis of the shaft 133 , and the second end cover 132 is fixed to the support rod 112 , so the support rod 112 and the shaft 133 can rotate relative to each other.

A friction ring 134 is sheathed on the positioning section 1331 , the friction ring 134 is located between the first end cover 131 and the second end cover 132 , and a positioning nut 137 is screwed into the threaded section 1332 . That is to say, the friction ring 134 is located between the first end cap 131 and the second end cap 132 , and one side thereof abuts against the first end cap 131 , and the other side abuts against the second end cap 132 . The positioning nut 137 can rotate on the threaded section 1332 to move a certain distance along the axis of the shaft 133 .

The elastic member 135 is sleeved in the positioning section 1331 and is located between the second end cap 132 and the positioning nut 137 and is in a compressed state, so as to provide the first end cap 131 , the second end cap 132 and the There is a positive pressure between the friction rings 134 , so that when the pivot rod 111 and the support rod 112 rotate relative to each other, a friction force is generated between the first end cap 131 , the second end cap 132 and the friction ring 134 .

That is to say, the elastic member 135 is clamped between the second end cover 132 and the positioning nut 137, and the gap between the positioning nut 137 and the second end cover 132 is smaller than the length of the elastic member 135 in a natural state, so that it is elastic. The member 135 is in a compressed state. In this way, the elastic member 135 provides a positive pressure along the axial direction of the shaft 133 in the compressed state. The positive pressure acts on the second end cover 132, so that the second end cover 132 and the friction ring 134 Adherence, the friction ring 134 is in close contact with the first end cover 131, thus, when the pivoting rod 111 rotates, due to the effect of positive pressure, the second end cover 132 and the friction ring 134, and the friction ring 134 and the first A frictional force is formed between the end caps 131, which acts as a resistance when the pivoting rod 111 and the support rod 112 rotate relative to each other, so that the pivoting rod 111 can be reliably stopped at this position after it rotates to a certain angle, thereby , to achieve reliable adjustment of the angle of the lamp.

It should be noted that since the positioning nut 137 can rotate and move on the threaded section 1332 , the compression amount of the elastic member 135 can be adjusted by adjusting the position of the positioning nut 137 on the shaft 133 , and then the adjustment along the axial direction of the shaft 133 can be adjusted. The positive pressure is finally used to adjust the friction between the second end cover 132 and the friction ring 134 , and the friction force between the friction ring 134 and the first end cover 131 . Therefore, if the rotation between the pivoting rod 111 and the supporting rod 112 is required to be tighter, the positioning nut 137 can be rotated with a wrench or the like to make the positioning nut 137 move in a direction close to the elastic member 135 . If the pivoting rod 111 and the supporting rod 112 need to be rotated more easily, the nut can be rotated with a wrench or other tool to move the positioning nut 137 away from the elastic member 135, which is more flexible and convenient to use. In addition, after using for a certain period of time, if the rotation between the pivoting rod 111 and the support rod 112 becomes loose due to wear, the positioning nut 137 can also be rotated to make the positioning nut 137 move closer to the elastic member 135. Move to fix looseness.

It can be understood that the elastic member 135 can be a disc spring or a compression spring, which can be directly sleeved on the shaft 133, and can provide a relatively large elastic effect, thereby increasing the frictional force.

Referring to Figure 6, in one embodiment of the present invention, the cross-section of the positioning section 1331 is non-circular, and correspondingly, the first end cover 131 is provided with a second An assembly hole 1311 , through which the first end cover 131 is interference-fitted on the positioning section 1331 to achieve synchronous rotation with the shaft 133 .

The arc surface cooperates to realize relative pivoting with the shaft 133 .

In this embodiment, the above-mentioned structure can realize the fixing between the first end cover 131 and the shaft 133 and the pivoting between the second end cover 132 and the shaft 133. The structure is simple, the assembly is convenient, and the fixing and pivoting are more reliable.

In one embodiment of the present utility model, the pivot mechanism 13 further includes a limiting member 136, which is fixed to the positioning section 1331, and the limiting member 136 has a notch 1361, the second A protrusion 1322 extending into the notch 1361 is formed on the end cover 132 in the axial direction. Relatively sliding inside.

That is to say, the limiting member 136 and the shaft rod 133 rotate synchronously. When the pivoting rod 111 and the supporting rod 112 rotate relative to each other, the notch 1361 on the limiting member 136 is opposite to the protrusion 1322 on the second end cover 132 slide. The size of the notch 1361 determines the sliding distance of the protrusion 1322 , and the protrusion 1322 is fixed to the second end cover 132 , therefore, the sliding distance of the protrusion 1322 in the notch 1361 defines the distance between the pivoting rod 111 and the supporting rod 112 . Angle range for relative rotation. In this embodiment, the relative rotation angle of the pivoting rod 111 and the supporting rod 112 is limited by the sliding fit between the notch 1361 on the limiting member 136 and the protrusion 1322 on the second end cover 132, and its structure Simple and solid.
