It generally consists of a mounting track, a spotlight body, and a connecting arm, as shown in Chinese Patent 202322499877.7. The connecting arm is rotatably connected to the spotlight body by bolts, and the connecting arm can rotate at a certain angle around the bolts as needed. Although this can meet general usage requirements, the connection arm and the spotlight body are mainly positioned by bolts. After repeated angle adjustments over a long period of time, the friction between the connecting arm and the bolts decreases, making it difficult to ensure the stability of the angle adjustment position and effectively limit the movement. Therefore, its applicability and practicality are limited. Summary of the Invention

[0009] A further preferred embodiment is that the cross-section of the limiting protrusion is semi-circular, and the cross-section of the strip groove is U-shaped;

[0010] A further preferred embodiment is that the height of the limiting protrusion is the same as the depth of the strip groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] See Figures 1 to 3 As shown, a rotating and limiting spotlight structure includes a spotlight body 1, a driver box 2, and a connecting arm 3 connecting the spotlight body and the driver box. A strip-shaped groove 4 is provided at one end of the side wall of the spotlight body. In this embodiment, the spotlight body, driver box, and connecting arm are all conventional structures of the prior art. The spotlight body or connecting arm is a plastic structure, and is simply used, so it is not described in detail. An axial protrusion 5 is integrally formed on the symmetrical inner wall of the strip-shaped groove, and a limiting protrusion 6 is integrally formed on the symmetrical inner wall of the strip-shaped groove. The limiting protrusion is located on the diameter extension line of the axial protrusion. In actual application, the limiting protrusion is vertically or horizontally arranged on the inner wall of the strip-shaped groove in a straight line. Furthermore, the cross-section of the limiting protrusion is semi-circular.

[0028] In this embodiment, a convex ring 7 is integrally formed on the lower symmetrical sidewall of the connecting arm. Several limiting grooves 8 are evenly distributed on the surface of the convex ring, and the cross-section of the strip groove is U-shaped. The symmetrical limiting grooves coincide with the diameter of the convex ring. The number of limiting grooves can be set as needed, and the symmetrical limiting grooves coincide with the diameter of the convex ring, allowing them to engage with the straight limiting protrusion during use. The limiting is achieved through the resistance between the limiting protrusion and the limiting groove; rotation is only possible when the external force exceeds this resistance. Compared to traditional methods relying on friction, this improves the stability and reliability of the limiting adjustment and reduces the likelihood of loosening or damage. In practical applications, the total thickness of the connecting arm plus the convex ring is the same as the width of the strip groove. During assembly, external pressure causes slight deformation of the spotlight body or connecting arm, resulting in the insertion of the shaft protrusion into the central hole of the convex ring. In practical applications, the height of the convex ring and shaft protrusion is typically around 1-2 cm. The above structure not only ensures the stability of the assembly, but also prevents it from loosening or falling off.

[0029] In this embodiment, during assembly, the lower part of the connecting arm is located in the strip groove, the shaft protrusion can be rotatably inserted into the central circular hole of the protrusion ring, and the limiting protrusion is inserted into the limiting groove; an external force drives the connecting arm to rotate around the shaft protrusion, and the limiting protrusion jumps in the adjacent limiting groove.

[0030] In practical applications, the height of the limiting protrusion is the same as the depth of the strip groove.

[0031] Meanwhile, in this embodiment, a circular through hole 9 is provided in the middle of the bottom wall of the drive box, and a plurality of hemispherical abutment grooves 10 are evenly provided on the bottom surface of the drive box. The hemispherical abutment grooves are evenly arranged around the circular through hole. Two arc-shaped snap-fit ​​spring pieces 11 are provided on the top surface of the connecting arm, and the diameter of the circle formed by the two arc-shaped snap-fit ​​spring pieces matches the inner diameter of the circular through hole. A ball 12 is provided on the top surface of the connecting arm. During assembly, the arc-shaped snap-fit ​​spring pieces of the connecting arm are engaged in the circular through hole, and the ball abuts into one of the hemispherical abutment grooves for limitation. When the connecting arm rotates in the circular through hole, the ball bounces in the adjacent hemispherical abutment grooves. The ball is a conventional structure in the prior art, so it is not described in detail. The two arc-shaped snap-fit ​​spring pieces are combined into a circle, and there is a buffer gap between them. During installation, they can be squeezed inward to facilitate the engagement of the two arc-shaped snap-fit ​​spring pieces for connection limitation, thereby improving the stability and reliability of the connection.

[0032] Furthermore, a C-shaped guide groove 13 is provided along the edge of the circular through hole, and a guide protrusion 14 is integrally formed on the top surface of the connecting arm, with the guide protrusion located at the edge of one of the arc-shaped snap-fit ​​spring pieces; the guide protrusion rotates and is limited within the C-shaped guide groove. This structure allows for rotation angle limitation, preventing damage to the wires from excessive rotation and improving stability and reliability during use.

[0033] This utility model has the following positive effects: The structure of this utility model is reasonably designed. One end of the side wall of the spotlight body is provided with a strip-shaped groove. An axle protrusion is integrally formed on the symmetrical inner wall of the strip-shaped groove, and a limiting protrusion is integrally formed on the symmetrical inner wall of the strip-shaped groove. A raised ring is integrally formed on the lower symmetrical side wall of the connecting arm, and the surface of the raised ring has uniformly distributed limiting grooves. The connection between the axle protrusion and the central hole of the raised ring improves the ease of assembly, reduces the use of bolts, and, through the cooperation of the limiting protrusion and the limiting groove, when the connecting arm is rotated by an external force, only when the external force exceeds the resistance between the limiting protrusion and the limiting groove can the limiting protrusion jump and limit itself within adjacent limiting grooves. This prevents damage to the limiting protrusion, improves the stability and reliability of the limiting, and also enhances the convenience of angle adjustment, making it easy to adjust and limit the angle. It has strong applicability.

[0034] Furthermore, a circular through hole is provided in the middle of the bottom wall of the drive box, and there is a hemispherical groove around the circular through hole. Together with the ball on the top surface of the connecting arm, the rotation direction adjustment can be limited, ensuring the effectiveness and reliability of the rotation direction adjustment. In addition, the rotation direction can also be limited by the C-shaped guide groove and guide protrusion to avoid damage to the wires due to excessive rotation, ensuring stable and reliable use, and making it highly applicable.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
