Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

As shown in Figures 1 to 10, the lamp installation bracket provided by the embodiment of the present invention is used to fix the lamp 100 to an external fixture, and the lamp installation bracket includes a fixture for fixed connection to the external fixture clamp 10, a lamp fixture 20 for clamping the lamp 100, and an angle adjusting device 30 connected between the fixture fixture 10 and the lamp fixture 20 and used for adjusting the angle of the lamp fixture 20; The angle adjustment device 30 includes a limiting housing 31 with a hinged ball groove 312, a hinged ball 32 connected to the lamp fixture 20 and hinged to the hinged ball groove 312, and connected to the fixture fixture 10 for using the The hinged ball 32 is locked to the locking mechanism 33 in the hinged ball groove 312 .

Specifically, in the lamp installation bracket of the embodiment of the present invention, the lamp 100 is clamped by the lamp fixture 20. Since the lamp fixture 20 is connected to the fixture fixture 10 through the angle adjustment device 30, the fixture fixture 10 is fixedly connected to the external The lamp 100 can be fixedly connected to the external fixture on the fixed object; since the hinged ball 32 connected to the lamp fixture 20 is hinged with the hinged ball groove 312 of the limit housing 31 to form a spherical hinge structure, then it can be achieved by applying an external force When it is on the lamp fixture 20, the lamp fixture 20 can realize rotation and swing relative to the limit housing 31, so as to realize the angle adjustment with at least three degrees of freedom in the axial, horizontal and vertical directions in the three-dimensional space, and complete the adjustment of the lamp fixture 20. After adjusting the angle of the hinged ball 32, the hinged ball 32 is locked in the hinged ball groove 312 by the locking mechanism 33, so that the hinged ball 32 is limited, so that the hinged ball 32 is fixed relative to the limit housing 31, thereby completing the alignment. The angle of the lamp 100 clamped on the lamp fixture 20 is adjusted, and the angle-adjusted lamp 100 is fixed; when the lamp 100 clamped by the lamp mounting bracket of the embodiment of the present invention is fixed on an external fixture, It can realize angle adjustment in multiple different directions, increase the operability of the lamp 100 and expand the irradiation range of the lamp 100, thereby increasing the application occasions of the lamp 100 and making the application range of the lamp 100 wider; and the overall The structure is simple and the manufacturing cost is low.

Further explain, the ball hinge structure formed by the hinged ball 32 and the hinged ball groove 312, since any contact point between the hinged ball 32 and the hinged ball groove 312 is a tangent point, the hinged ball 32 and the hinged ball groove 312 can be realized in this way. In theory, relative 360° rotation at any angle; but in this embodiment, since the angle adjustment device 30 also has other components, the hinged ball 32 can still achieve an axial rotation with the hinged ball groove 312 under the interference of other components. 360° rotation and swing in other directions can still adjust the angle of the lamp fixture 20 at multiple angles, so that the lamp 100 clamped on the lamp fixture 20 can be adjusted at multiple angles.

As shown in Figures 1-3 and Figure 9, in this embodiment, the locking mechanism 33 includes a limiting ball seat 331, a moving slider 332 and a driving bolt 333; the limiting housing 31 is provided with A through hole 311, the aperture of the first end of the through hole 311 is smaller than the ball diameter of the hinged ball 32, the aperture of the second end is larger than the ball diameter of the hinged ball 32, the hinged ball groove 312 is located in the through hole In the hole 311 and close to the first end of the through hole 311, the limit ball seat 331 is arranged in the through hole 311 and is fixedly connected with the fixture fixture 10, and the moving slider 332 is arranged in the The through hole 311 is located between the position limiting ball seat 331 and the fixture fixture 10 , and a first threaded hole 313 communicated with the through hole 311 is provided on the side of the position limiting housing 31 . The driving bolt 333 is threadedly connected with the first threaded hole 313 and the end of the driving bolt 333 is mated with the moving slider 332 to drive the moving slider 332 along the length direction of the through hole 311 move. Wherein, the function of the position-limiting housing 31 is to limit the position-limiting ball seat 331 and the hinged ball 32 hingedly connected in the through hole 311, and because the hinged ball 32 is arranged near one end of the through hole 311, the aperture diameter is smaller than that of the hinged ball 32. diameter position, so that the hinged ball 32 can be avoided so that the port of the through hole 311 is out; In the slot 312, part of the structure of the hinged ball 32 protrudes to the outside of the through hole 311 whose aperture is smaller than the end of the hinged ball 32, and is fixedly connected with the lamp fixture 20, and then the limit ball seat 331 is put into the through hole 311 and hinged. The sphere 32 abuts, and the limit ball seat 331 is fixedly connected to the fixture fixture 10 on the other side opposite to the hinged sphere 32, that is, the limit ball seat 331 and the hinged sphere 32 that realize the hinged connection are all limited in the limit housing 31. In the through hole 311 , it can ensure that when the hinge ball 32 rotates relative to the hinge ball groove 312 , it will not fall off, ensuring the reliability of the angle adjustment of the lamp 100 .

As shown in FIGS. 1-3 and FIG. 9 , the specific working process of the angle adjusting device 30 is: loosen the driving bolt 333, and contact the force applied by the driving bolt 333 to the moving slider 332, so that the moving slider 332 is in contact with the limit position. A gap is formed between the ball seats 331, so that a gap is formed between the limit ball seat 331 and the hinged ball 32. Due to the existence of the gap, the hinged ball 32 is in a movable state, that is, the hinged ball 32 is in the hinged ball groove 312. Rotation can be realized inside, the hinged sphere 32 is connected with the lamp fixture 20, then the lamp fixture 20 can be rotated, thereby realizing the angle adjustment of the lamp 100 clamped on the lamp fixture 20; After the angle of 100 is adjusted, the driving bolt 333 is tightened, and the driving bolt 333 drives the moving slider 332 along the length direction of the through hole 311 and moves towards the limit position under the cooperation of the driving bolt 333 at its end and the moving slider 332. Fixed on the external fixture, the limit ball seat 331 is fixedly connected with the fixture fixture 10 and is in a motionless state. At this time, under the action of the limit shell 31, the limit shell 31 moves towards the fixture fixture 10, limiting The position housing 31 then pulls the hinged ball 32 through the hinged ball groove 312 to move towards the direction of the limit ball seat 331 until the hinged ball 32 is tightly attached to the limit ball seat 331, and the limit ball seat 331 realizes the hinged ball. 32 is locked in the hinge ball groove 312, so that the lamp fixture 20 is limited, so that the lamp fixture 20 can be prevented from rotating, and the lamp 100 clamped on the lamp fixture 20 after adjusting the angle is stable and not loose. Realize its directional irradiation function. In this way, the angle adjusting device 30 in this embodiment can not only ensure multiple angle adjustments to the clamped lamp 100 , but also can lock the hinged ball 32 after completing the angle adjustment of the clamped lamp 100 . The positioning of the clamped lamp 100 is realized, the structural design is ingenious, and the practicability is strong.
