Detailed Implementation

[0032] 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 1

[0033] See Figures 1 to 3As shown, a spotlight structure with a locking connection includes a lamp body 1, a power supply 2, and a connecting rod 3. In this embodiment, the lamp body is a spotlight body, and the power supply is a conventional structure in the prior art, so it is not described in detail.

[0034] In practical applications, the upper side wall of the lamp body is provided with a connecting groove 4 with an open top surface. The openings on the side and top allow the connecting rod to rotate and adjust within a 90-degree range, meeting different angle adjustment requirements. Simultaneously, a convex shaft 5 is integrally formed on the lower part of the symmetrical inner wall of the connecting groove, and an arc-shaped protrusion 6 is integrally formed on the symmetrical inner wall of the connecting groove. The arc-shaped protrusion is located at both ends of the diameter of the convex shaft. The arc-shaped protrusion is used to cooperate with and press against the arc-shaped groove to limit its position after angle adjustment, ensuring the stability of the angle position. Reliability; and the lower part of the symmetrical sidewall of the connecting rod is integrally formed with a circular protrusion 7, the center of which is provided with a circular hole 8 that mates with the convex shaft; the circular protrusion is radially provided with a plurality of pressing arc-shaped grooves 9; during assembly, the connecting rod is inserted into the connecting strip groove, the convex shaft is inserted into the circular hole, and the arc-shaped protrusion is inserted into the pressing arc-shaped groove; the connecting rod rotates around the convex shaft, and the arc-shaped protrusion jumps in the adjacent pressing arc-shaped groove and is limited by the arc-shaped protrusion and the pressing arc-shaped groove when there is no external force. It is connected by the convex shaft and the circular hole, which reduces the use of screws, and in this embodiment, the width of the connecting strip groove matches the width of the connecting rod; the height of the convex shaft and the circular protrusion are both 5-10mm; the height of the arc-shaped protrusion is less than or equal to the height of the convex shaft. In addition, the connecting rod is a hollow plastic rod or a hollow metal rod. Meanwhile, the lamp housing is also made of plastic. During assembly, it mainly utilizes the slight deformation properties of the lamp body and the connecting rod. When the external force is large, the connecting rod can be forced into the connecting groove and the convex shaft can be locked into the round hole. This not only ensures smooth rotation but also prevents loosening or falling off, improving the stability and effectiveness of use. Furthermore, through the cooperation of the arc-shaped convex strip and the arc-shaped groove, the arc-shaped convex strip will squeeze and jump between adjacent arc-shaped grooves during angle adjustment. After angle adjustment, the two can be used to limit the position, ensuring the stability of angle adjustment.

[0035] In practical applications, the power supply has a through hole 10 on its bottom wall and several hemispherical pressure grooves 11 centered on the through hole on its bottom surface. The top of the connecting rod has two semi-circular snap-fit ​​ears 12, which combine to form a complete cylindrical ear with a buffer gap between them. A ball bearing 13 is located on the top surface of the connecting rod. During assembly, the two semi-circular snap-fit ​​ears are engaged in the through hole for positioning, and the top surface of the ball bearing is engaged in one of the hemispherical pressure grooves. During use, when the connecting rod rotates around the two semi-circular snap-fit ​​ears, the ball bearing bounces within adjacent hemispherical pressure grooves and is positioned by the ball bearing and the hemispherical pressure groove when no external force is applied. This structure allows for relative rotation between the connecting rod and the power supply, enabling lighting in different directions. Furthermore, the ball bearing, in conjunction with the hemispherical pressure groove, provides positioning stability and reliability in the direction of rotation.

[0036] In this embodiment, the arc-shaped protrusion is aligned with the axial direction of the lamp body. Therefore, when the connecting rod is inserted into the connecting groove, the arc-shaped protrusion can abut against the side of the connecting rod to position it, ensuring stability and reliability at the corresponding position.

[0037] Furthermore, in this embodiment, a limiting protrusion 14 is provided on the bottom wall of the through hole, and a limiting stop 15 is provided on the top surface of the connecting rod; when the connecting rod rotates within the through hole, the rotation is limited by the limiting protrusion and the limiting stop. Through this structure, the direction of rotation can be limited, keeping the rotation range between 0 and 355 degrees, thus preventing damage to the wires caused by rotation.

[0038] This utility model has positive effects: The structure of this utility model is reasonably designed. It uses a convex shaft to fit into the round hole of the connecting support rod, and cooperates with the arc-shaped convex strip and the pressing arc-shaped groove. This not only improves the convenience of connection, but also limits the position after rotation through the arc-shaped convex strip and the pressing arc-shaped groove, improving the effectiveness and stability of angle adjustment. It also reduces the use of bolts, which is conducive to improving the convenience of disassembly and assembly, and has strong applicability.

[0039] Furthermore, when the connecting rod rotates around the two semi-circular buckle lugs, it can be limited by the ball and the semi-bead-shaped pressing groove, which can realize the rotation adjustment operation between the connecting rod and the power supply, meet the lighting needs of different angles and directions, and improve its applicability. Moreover, it does not require bolts or screws, which improves the convenience and stability of assembly. Example 2

[0040] See Figures 4 to 5 As shown, this embodiment is basically the same as embodiment 1, except that the arc-shaped protrusion is the same as the radial direction of the lamp body.

[0041] 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.

[0042] 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.
