Description

Technical Field

[0001] The present invention relates to the technical field of stage lighting, and in particular to an optical effect device and a stage light that can be quickly disassembled and assembled. Background Art

[0002] In the Chinese utility model patent with the publication number CN221258679U, specifically in paragraph

[0023] of the specification, the following content is disclosed: A quickly disassemblable effect part and an effect module and a stage light having the same. Among them, a quickly disassemblable effect part includes a bracket and an effect sheet. One end of the bracket is provided with a light passing hole for light to pass through, and the effect sheet is located above the light passing hole. A receiving groove for supporting the effect sheet is formed by a depression on the side wall of the light passing hole; it also includes a pressing plate for fixedly installing the effect sheet on the bracket. The pressing plate is movably arranged on the bracket and has a first position allowing the effect sheet to be placed into the receiving groove, and a second position in which the effect sheet is restricted in the receiving groove after being locked with a locking member on the bracket.

[0003] After placing the effect sheet in the receiving groove and moving the pressing plate to the second position, then use the cooperation between the pressing plate and the locking member to fix the effect sheet in the bracket to prevent it from falling during operation; when it is necessary to remove the effect sheet for replacement or maintenance, only need to release the locking state between the locking member and the pressing plate, and then move the pressing plate to the first position to easily take out the effect sheet, realizing quick and more convenient disassembly and assembly of the effect sheet.

[0004] The defects faced by the above technical solutions are: when the effect sheet is locked, first place the effect sheet into the receiving groove from top to bottom, and then rotate the pressing plate to the second position. The pressing plate and the locking member cooperate to fix the effect in the receiving groove; when the effect sheet is unlocked, it is necessary to unlock the pressing plate and the locking member before rotating the pressing plate to the first position, and only then can the effect sheet be taken out of the receiving groove. It can be seen that it is necessary to switch different positions of the pressing plate back and forth, and this operation step is relatively cumbersome. In addition, for the clamping structure in which the pressing plate and the locking member cooperate (that is, the rivet and the clamping notch cooperate to clamp), whether it is locking or unlocking, a relatively large force needs to be applied, which is very unfavorable for disassembly and assembly. Summary of the Invention

[0005] The present invention provides an optical effect device and a stage light that can be quickly disassembled and assembled to solve one of the above technical problems, and the disassembly and assembly of the effect part are more convenient and fast, and the fixing stability is good.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] A quickly disassembled optical effect device comprises a bracket, an effect sheet and an elastic pressure plate, the bracket is provided with a light-through hole for light to pass through, the inner wall of the light-through hole is recessed to form a receiving groove for supporting the effect sheet, the effect sheet is located at the light-through hole, the elastic pressure plate comprises a fixing portion, the elastic pressure plate is fixed to the bracket through the fixing portion and the effect sheet is fixedly installed in the receiving groove, so that the effect sheet is relatively fixed in the axial direction of the light-through hole, the receiving groove has an opening opened in the radial direction of the light-through hole, the effect sheet can be inserted into or withdrawn from the receiving groove through the opening in the radial direction of the light-through hole, the elastic pressure plate also comprises an elastic portion extending from one end of the fixing portion to the opening, the elastic portion is fixedly provided with a stopper for limiting the radial movement of the effect sheet after being inserted into the receiving groove.

[0008] As a preferred embodiment, it is further defined that the stopper is a rivet post, and after the effect sheet is inserted into the receiving groove, the rivet post abuts against the outer peripheral surface of the effect sheet.

[0009] As a preferred embodiment, it is further defined that the effect piece is circular in shape, and the length L1 of the opening is greater than the maximum diameter D of the effect piece.

[0010] As a preferred embodiment, it is further defined that the maximum distance L2 between the stopper and one end of the opening is smaller than the maximum diameter D of the effect sheet.

[0011] As a preferred embodiment, it is further defined that after the effect sheet is inserted into the receiving groove, the inner edge of the elastic pressure plate presses the effect sheet tightly to fix it in the receiving groove.

[0012] As a preferred embodiment, it is further defined that the effect sheet is an atomizing sheet.

[0013] A stage lamp comprises a light source and the optical effect device, wherein the light of the light source is emitted through the optical effect device.

[0014] After adopting the above technical solution, the invention has at least the following beneficial effects: when installing, first press the stopper to move it longitudinally, the stopper is staggered with the opening position of the receiving groove, then the effect sheet is inserted into the receiving groove through the opening, and finally the stopper is released. Since the elastic part has a certain elasticity, the elastic part is reset to the initial position. At this time, the stopper and the effect sheet remain against each other, thereby completing the fixation of the effect sheet; when disassembling, press the stopper again to move it longitudinally, and after the stopper and the opening position of the receiving groove are staggered, the effect sheet is pulled out to complete the disassembly. The optical effect device created by the invention can complete the disassembly or installation of the effect sheet only by pressing the stopper. The installation step is convenient and quick, and the fixing stability is good. Description of the Drawings

[0018] 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 describes this application in detail with reference to the drawings and specific embodiments.

[0019] As shown in the attached Figures 1 to 3 figures, an optical effect device that can be quickly disassembled and assembled and a stage light thereof. Among them, an optical effect device that can be quickly disassembled and assembled includes a bracket 1, an effect sheet 2, and an elastic pressing plate 3. The effect sheet 2 is an atomizing sheet. A light passing hole 10 for the light of the light source of the stage light to pass through is formed on the bracket 1. A receiving groove 11 for supporting the effect sheet 2 is recessed on the inner wall of the light passing hole 10. The effect sheet 2 is located at the light passing hole 10. The elastic pressing plate 3 includes a fixing portion 31. The elastic pressing plate 3 is fixed on the bracket 1 through the fixing portion 31 and fixes and installs the effect sheet 2 in the receiving groove 11, so that the effect sheet 2 is relatively fixed in the axial direction of the light passing hole 10. The receiving groove 11 has an opening 100 opened in the radial direction of the light passing hole 10. The effect sheet 2 can be inserted into the receiving groove 11 or withdrawn from the receiving groove 11 through the opening 100 in the radial direction of the light passing hole 10. The elastic pressing plate 3 further includes an elastic portion 32 extending from one end of the fixing portion 31 to the opening 100. A stop member 4 for restricting the radial movement of the effect sheet 2 after being inserted into the receiving groove 11 is fixedly arranged on the elastic portion 32.

[0020] Specifically, the steps are as follows. During installation, first press the stop member 4 to move it longitudinally so that the stop member 4 is offset from the position of the opening 100 of the receiving groove 11. Then insert the effect sheet 2 into the receiving groove 11 through the opening 100. Finally, release the stop member 4. Since the elastic portion 32 has a certain elasticity, the elastic portion 32 returns to its initial position. At this time, the stop member 4 abuts against the effect sheet 2, thus completing the fixing of the effect sheet. During disassembly, press the stop member 4 again to move it longitudinally. After the stop member 4 is offset from the position of the opening 100 of the receiving groove 11, the effect sheet 2 can be withdrawn to complete the disassembly. The optical effect device of the present invention can complete the disassembly or installation of the effect sheet only by pressing the stop member 4. The installation steps are convenient and fast, and the fixing stability is good.

[0021] As shown in the appendix Figure 3 As shown, the effect piece 2 is circular in shape, and the length L1 of the opening 100 is greater than the maximum diameter D of the effect piece 2, so that there is enough space for the effect piece to be inserted into the opening 100.

[0022] In this embodiment, the stopper 4 is a rivet post. After the effect piece 2 is inserted into the receiving groove 11, the rivet post abuts against the outer peripheral surface of the effect piece 2. Specifically, as shown in the appendix Figure 3 As shown, the maximum distance L2 between the stopper 4 and one end of the opening 100 is less than the maximum diameter D of the effect piece 2, so that the stopper 4 plays a blocking role, thereby completing the radial fixation of the effect piece 2.

[0023] In this embodiment, after the effect piece 2 is inserted into the receiving groove 11, the inner edge of the elastic pressing plate 3 tightly presses the effect piece 2 to fix it in the receiving groove 11, thereby completing the axial fixation of the effect piece 2.

[0024] 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
