[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The technical solution of the present invention is further explained below in conjunction with the accompanying drawings and embodiments.

[0019] Reference Figure 1-3 In one embodiment, the light shield structure for installation on the stage light includes a base 101, and a plurality of installation positions 102 are provided on the periphery of the base 101, such as Figure 1As shown, there are four mounting positions 102, each mounting position 102 is fixedly connected to the first matching member 201, the first matching member 201 is connected to the first end 302 of the second matching member 301 through a damping shaft, the second matching member 301 includes a first end 302 and a second end 303, the second end 303 of the second matching member 301 is fixedly connected to the blade 401, and a notch 402 is provided on the periphery of the blade 401, the notch 402 is used to avoid the first matching member 201 and the second end 303 of the second matching member 301, the rotation angle of the blade 401 is manually determined, and in this embodiment, the light shielding structure A plurality of mounting positions 102 are provided on the periphery of the base 101, and each mounting position 102 is fixedly connected to the first mating piece 201. The first mating piece 201 is connected to the first end 302 of the second mating piece 301 through a damping shaft, and the second end 303 of the second mating piece 301 is fixedly connected to the blade 401. The blade 401 will not shake when it stops at any angle, and the damping effect is good. In addition, a notch 402 is provided on the periphery of the blade 401. The notch 402 is used to avoid the first mating piece 201 and the second end 303 of the second mating piece 301, so that the blade 401 will not be blocked when rotating.

[0020] Continue to refer to Figure 2 In one embodiment, each mounting position 102 is an outer convex structure on the outer periphery of the base 101, which is conducive to the second matching member 301 not being affected by other structural parts when rotating.

[0021] Specifically, continue to refer to Figure 2 A convex plate 103 is provided on one side of the mounting position 102 away from the base 101. The convex plate 103 is oriented in the opposite direction to the placement direction of the first matching member 201. Figure 2 From the perspective of placement, the placement direction is from top to bottom, so the convex plate 103 protrudes from bottom to top, so that when the first matching member 201 is installed in the installation position 102, it limits the first matching member 201, thereby facilitating installation.

[0022] In one embodiment, the outer convex width of the convex plate 103 is L, the width of the second matching component 301 is D, and L>D, which further ensures that when the blade 401 rotates, combined with the effect of the damping shaft, the second matching component 301 can rotate relative to the first matching component 201 and is not affected by other structural components during rotation.

[0023] In one embodiment, the second end 303 of the second matching member 301 contacts the blade 401 on the side facing the blade 401 , thereby improving the structural compactness of the second matching member 301 and the blade 401 and preventing the final light barrier structure from being too large.

[0024] Furthermore, in one embodiment, one first fitting member 201 corresponds to two second fitting members 301, and the two second fitting members 301 are respectively located at both ends of the first fitting member 201. Since the second fitting members 301 are also fixedly connected to the blade 401, this combination greatly improves the stability of the blade 401 when it is selected.

[0025] In one embodiment, the mounting position 102 is fixedly connected to the first matching member 201 by bolts, and the second end 303 of the second matching member 301 is fixedly connected to the blade 401 by bolts. In other embodiments, the fixed connection method may also include bonding or hot melting.

[0026] In the figure, the description of the positional relationship is only for illustrative purposes and cannot be understood as a limitation of this patent; obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not limitations on the implementation methods of the utility model.
