[0002] In the field of stage lighting technology, in order to achieve rich stage lighting effects, various optical elements, such as pattern pieces, prism sheets, etc., are usually required. In order to facilitate the maintenance of optical elements, optical elements are generally designed as detachable structures. For example, the existing prism device includes a prism assembly and a prism mount. The prism assembly and the prism mount are clamped on the edge periphery of the two through the baffle of the snap plate. At the same time, positioning protrusions are provided on the snap plate, and positioning holes are provided on the prism mount; when buckled, the positioning protrusions and the positioning holes are matched. The above-mentioned prior art structure can be found in the invention patent with publication number CN107795962B; however, the defect faced by this detachable structure is that due to the principle of matching and engaging the positioning protrusions and the positioning holes, the snap plate is very difficult to break open, which increases the difficulty of disassembly.

[0003] In order to overcome the defect of being difficult to disassemble, a semi-circular spring piece is provided on the prism mount, and a gap is left between the prism mount and the spring piece, and the prism assembly is embedded in the gap so that the prism assembly is clamped in the spring piece, such as the spring piece structure disclosed in publication number CN210035377U; however, although this structure is convenient for disassembly, when the prism assembly is driven to rotate, since the spring piece always has a certain elasticity, the prism assembly shakes slightly when it rotates, resulting in poor stability of the prism assembly rotation, affecting the lighting effect. Summary of the invention

[0004] The present invention is to solve one of the above technical problems and provide a convenient detachable optical device and a stage light thereof, which has the advantages of good stability and quick disassembly or installation.

[0024] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following further elaborates on this application in conjunction with the drawings and specific embodiments.

[0025] As shown in Figure 1 to Figure 7 shown, a portable and disassemblable optical device includes a base 1, a fixing part 2, a spring piece 3, and an effect component 4. A light - passing port 11 for the beam to pass through is provided on the base 1. The spring piece 3 includes an integrally formed fixing part 31 and an elastic engaging part 32. The fixing part 31 is fixedly clamped between the base 1 and the fixing part 2. The fixing part 31, the base 1, and the fixing part 2 together form an installation groove 100 with the notch facing the center of the light - passing port 11. The effect component 4 is adaptively placed in the installation groove 100. The elastic engaging part 32 extends out of one end of the fixing part 2, and the elastic engaging part 32 is clamped on the outer peripheral surface of the effect component 4. Specifically, the base 1, the spring piece 3, and the fixing part 2 are fixedly connected in sequence from bottom to top through a threaded fixing piece, so that the three of them mutually form an installation groove 100 for the effect component 4 to be inserted and matched.

[0026] The installation steps are as follows: first, a force is applied to the elastic snap-fit ​​portion 32 of the spring sheet 3 to slightly bend it longitudinally and slightly open it radially outward. At this time, the elastic snap-fit ​​portion 32 and the installation slot 100 are offset up and down, and then the effect component 4 is inserted into the installation slot 100 from the radial direction. Finally, the spring sheet 3 is released. Due to the elastic action, the spring sheet 3 can maintain contact with the effect component 4, thereby preventing the effect component 4 from escaping from the radial direction; therefore, the installation slot 100 can effectively enhance the stability of the effect component 4, and the spring sheet 3 can improve the efficiency of quick disassembly or installation of the effect component 4.

[0027] As attached Figure 3 As shown, the free end of the elastic clamping portion 32 is provided with a protrusion 321 protruding toward the center of the light opening 11, and the elastic clamping portion 32 abuts against the outer peripheral surface of the effect component 4 through the protrusion 321. The protrusion 321 can increase the clamping force of the elastic clamping portion 32 on the effect component 4, thereby playing a role in preventing loosening.

[0028] As attached Figure 4 To Attachment Figure 6 As shown, the effect component 4 includes an annular base plate 41, an annular shaft seat 42, an annular gear 43 and an optical effect piece 44. The annular shaft seat 42 is fixed on the annular base plate 41, the annular gear 43 is sleeved in the annular shaft seat 42 and can rotate relative to the annular shaft seat 42, the optical effect piece 44 is fixed in the inner ring of the annular gear 43 and rotates therewith. When the effect component 4 is plugged into the mounting groove 100 through the annular base plate 41, the elastic clamping portion 32 is clamped on the circumferential surface of the annular shaft seat 42, and the motor can engage with the annular gear 43 through the transmission gear, thereby driving the rotation of the optical effect piece 44. Specifically, the elastic clamping portion 32 is maintained in contact with the outer circumferential surface of the annular shaft seat 42 through the convex point 321 to ensure the fixation of the effect component 4. Preferably, the optical effect piece 44 is a prism, a pattern piece, etc.

[0029] As attached Figure 7 As shown, a portion of the inner side surface of the fixing member 2 is recessed to form an arc-shaped notch 21, and the arc-shaped notch 21, the base 1, and the fixing portion 31 together form the mounting groove 100, and the inner side surface of the arc-shaped notch 21 is flush with the inner side surface of the spring piece 3, so that the inner side surface of the mounting groove 100 is flat; the other portion protrudes to form an arc-shaped opening 22, and the arc-shaped opening 22 is adapted to the annular shaft seat 42.

[0030] As attached Figure 3As shown, the elastic piece 3 and the fixing piece 2 are both arc-shaped, which facilitates the corresponding matching of these components with the effect component 4 to improve the matching degree among the components. Further, the radian of the elastic piece 3 is greater than π and less than 2π, so that the elastic piece 3 can effectively engage with the annular shaft seat 42. And the radian of the fixing piece 2 is greater than zero and less than or equal to π, so that the annular bottom plate 41 is inserted into the installation groove 100 from the radial direction.

[0031] In this embodiment, the light passing port 11 is a semi-circular arc-shaped port or a circular port. After the effect component 4 is installed, the optical effect piece 44 is directly opposite to the light passing port 11 in the axial direction, and the light beam can pass through the light passing port 11 and the optical effect piece 44 in sequence to achieve the stage lighting effect.

[0032] The present invention also provides a stage lamp, including a light source and the optical device as described above, and the light beam of the light source is emitted through the optical device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various equivalent changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
