Description

Technical Field

[0001] The utility model relates to the field of apertures of light cutting disks, in particular to an aperture with a simplified structure. Background Art

[0002] Lighting cutting discs are commonly used in stage performances, concerts, plays, dances, and other theatrical performances. They create diverse lighting effects for performers and artists, enhancing the audience's visual impact and sense of engagement. A key component in achieving this function is the aperture, which adjusts the amount of light passing through it, thereby collaborating with other components to achieve different lighting effects.

[0003] The existing aperture structure is relatively complex and not stable enough, which makes it inconvenient to produce, process, assemble and use. Therefore, it is necessary to invent an aperture with a simplified structure, easy processing and assembly, high stability and better durability. Utility Model Content

[0004] The main purpose of the utility model is to provide an aperture with a simplified structure, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A simplified-structured aperture is provided with an aperture drive unit, a shading unit, and a mounting base unit, which are sequentially assembled from top to bottom. The aperture drive unit is provided with an aperture top cover and a bearing ring, the shading unit is provided with a shading module, and the mounting base unit is provided with an aperture base. The aperture drive unit and the shading unit are detachably connected, and the shading unit and the mounting base unit are detachably connected, so that the overall assembly forms an aperture with a simplified structure.

[0007] Furthermore, the aperture top cover is integrally formed.

[0008] Furthermore, the aperture top cover is provided with a fixed layer, a half gear, and an anti-reflection step. The fixed layer is located below the aperture top cover. An inner ring raceway is provided on the outer edge of the fixed layer. The structure of the inner ring raceway is an inwardly concave guide groove structure. A number of fixing holes are provided below the fixed layer. The half gear is provided on one side of the aperture top cover, and the anti-reflection step is provided above the aperture top cover.

[0009] Furthermore, the bearing ring is nested on the outside of the fixed layer, and an outer ring raceway is provided on the inner edge of the bearing ring. The structure of the outer ring raceway is L-shaped, and a number of rolling bodies are provided between the outer ring raceway and the inner ring raceway. The outer ring raceway connects the fixed layer and the bearing ring in the vertical direction by pressing the rolling bodies into the inner ring raceway, thereby combining the aperture drive unit as a whole, and uses the rolling bodies in the horizontal direction to achieve the effect of relative rotation with very little wear. A number of ring locking holes are opened on the bearing ring.

[0010] Furthermore, a shading module is provided below the bearing ring, and an aperture base is provided below the shading module. A number of base locking holes are provided on the aperture base, and the base locking holes correspond to the ring locking holes. A number of locking pins are provided below the aperture base, and the locking pins are inserted into the base locking holes and then inserted into the ring locking holes, thereby realizing a detachable connection, achieving the effect of fixedly connecting the bearing ring and the aperture base, and thereby achieving the effect of combining the aperture drive unit with the shading unit and the mounting base unit.

[0011] Furthermore, the shading module is composed of several superimposed arc-shaped shading sheets, each of which is provided with a middle hole and an outer hole. An upper limit pin is fixedly installed on the middle hole of the shading sheet, which protrudes toward the direction of the aperture top cover and is inserted into the fixed hole. A lower limit pin is fixedly installed on the outer hole of the shading sheet, which protrudes in the opposite direction of the aperture top cover.

[0012] Furthermore, a guide groove is provided on the aperture base, and the lower limit pin is inserted into the guide groove. A plurality of base through holes are provided below the aperture base, and symmetrical base grooves are provided below the aperture base. The base through holes and the base grooves are used to fix the aperture base on other devices.

[0013] The beneficial effects of the utility model are:

[0014] 1. In the present invention, the aperture is composed of only three main structural units, with the aperture top cover of the aperture drive unit being integrally formed. This reduced number of components simplifies the processing and assembly of the aperture components during production. The aperture drive unit and the light shielding unit within the aperture are vertically connected through the outer raceway of the bearing ring, the inner raceway of the fixed layer, and the interaction of the rolling elements, thereby integrating the aperture drive unit. The light shielding unit and the mounting base unit are connected through the fixing holes in the fixed layer and the base locking holes in the aperture base. Locking pins are then inserted and threaded together to conveniently secure the light shielding unit and the mounting base unit. This simple and stable connection makes the aperture assembly process more intuitive and efficient, while significantly reducing quality issues caused by assembly errors and improving overall production efficiency.

[0015] 2. In this utility model, the aperture's simple structure reduces moving parts within the aperture, making the overall design more stable and reliable. Fewer moving parts reduces potential failure points during prolonged use, effectively improving the aperture's durability. This structural design allows it to withstand even harsher operating environments, extending its service life and making it ideal for applications requiring long-term, trouble-free operation.

[0016] 3. The simplified structure and easy assembly of this utility model facilitate routine maintenance and replacement. In the event of a malfunction, on-site disassembly and replacement of parts are quick and easy. Fewer components also reduce weight, making it particularly advantageous for installation in light cutting discs that require constant movement. This also significantly facilitates logistics and transportation, effectively improving cost-effectiveness.

[0017] 4. In this invention, the anti-reflection step structure of the aperture top cover can effectively prevent the light from being refracted inward on the aperture top cover after being emitted, thereby affecting the illumination of the main light column. This structure can effectively improve the illumination effect of the light. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example

[0031] like Figure 1-10As shown, a simplified aperture is provided with an aperture drive unit 1, a shading unit 2 and a mounting base unit 3, which are sequentially assembled from top to bottom. The aperture drive unit 1 is provided with an aperture top cover 110 and a bearing ring 120, the shading unit 2 is provided with a shading module 210, and the mounting base unit 3 is provided with an aperture base 310. The aperture top cover 110 is formed as a whole through integral processing. The aperture top cover 110 is provided with a fixing layer 112, a half gear 111 and an anti-reflection step 115. The fixing layer 112 is located below the aperture top cover 110. An inner ring raceway 113 is provided on the outer edge of the fixing layer 112. The structure of the inner ring raceway 113 is an inwardly concave guide groove structure. A plurality of fixing holes 114 are provided below the fixing layer 112. The half gear 111 is provided on one side of the aperture top cover 110, and the anti-reflection step 115 is provided above the aperture top cover 110. The bearing ring 120 is nested on the outside of the fixed layer 112. The inner edge of the bearing ring 120 is provided with an outer ring raceway 121. The structure of the outer ring raceway 121 is L-shaped. 92 rolling elements 122 are provided between the outer ring raceway 121 and the inner ring raceway 113. The outer ring raceway 121 presses the rolling elements 122 into the inner ring raceway 113. The L-shaped structure of the outer ring raceway 121, the concave structure of the inner ring raceway 113, and the ball bearing structure formed by the rolling elements 122 are combined to make the fixed layer 112 and the bearing ring 120 connected to each other in the vertical direction, thereby combining the aperture drive unit 1 as a whole, and using the rolling elements 122 in the horizontal direction to achieve the effect of relative rotation with very little wear. There are four ring locking holes 123 on the bearing ring 120, and a shading module 210 is arranged below the bearing ring 120. An aperture base 310 is arranged below the shading module 210, and four base locking holes 312 are arranged on the aperture base 310. The base locking holes 312 correspond to the ring locking holes 123. Four locking pins 313 are arranged below the aperture base 310. The locking pins 313 are inserted into the base locking holes 312 and then into the ring locking holes 123, thereby realizing a threaded connection, thereby achieving the effect of fixedly connecting the bearing ring 120 and the aperture base 310, and thereby achieving the effect of fixedly connecting the aperture drive unit 1 with the shading unit 2 and the mounting base unit 3. The shading module 210 is composed of 16 stacked arc-shaped shading sheets 211, each of which is provided with a middle hole 212 and an outer hole 213. An upper limit pin 214 is fixedly installed on the middle hole 212 of the shading sheet. The upper limit pin 214 protrudes toward the direction of the aperture top cover 110 and is inserted into the fixing hole 114. A lower limit pin 215 is fixedly installed on the outer hole 213 of the shading sheet. The lower limit pin 215 protrudes in the opposite direction of the aperture top cover 110.A guide groove 311 is provided on the aperture base 310, and the lower limit pin 215 is inserted into the guide groove 311. Four base through holes 314 are provided below the aperture base 310. A pair of symmetrical base grooves 315 are provided below the aperture base 310. The base through holes 314 and the base grooves 315 can be used to clip the aperture base 310 into and fix it to other devices.

[0032] Assembly principle of the aperture:

[0033] During assembly, the bearing ring 120 is inserted into the fixed layer 112 of the aperture top cover 110, and then the rolling body 122 is placed between the inner ring raceway 113 and the outer ring raceway 121. Due to the concave guide groove structure of the inner ring raceway 113 and the L-shaped structure of the outer ring raceway 121, the bearing ring 120 is combined with the aperture top cover 110, and the two are fixed in the horizontal direction and can rotate relative to each other in the vertical direction. Then the arc-shaped light-shielding sheet 211 in the light-shielding module 210 is stacked in sequence and the upper limit pin 214 is inserted into the fixing hole 114. Subsequently, the aperture base 310 is combined with the bearing ring 120, the ring locking hole 123 is matched one by one with the base locking hole 312, and the lower limit pin 215 of the arc-shaped light-shielding sheet 211 is inserted into the guide groove 311. Finally, the locking pin 313 is spirally inserted into the ring locking hole 123 and the base locking hole 312 to fix the bearing ring 120 to the aperture base 310. Since the bearing ring 120 and the aperture top cover 110 are combined with each other, the complete assembly of the entire aperture drive unit 1, the light-shielding unit 2 and the mounting base unit 3 is completed.

[0034] The operating principle of this aperture:

[0035] During use, the aperture is first fixed to the external bottom device through the base groove 315 and the base through hole 314 on the aperture base 310, and then the external rotating device is engaged with the half gear 111. When the external rotating device rotates, the half gear 111 rotates synchronously, and then drives the aperture top cover 110 and the fixed layer 112 to rotate. The inner ring raceway 113, the outer ring raceway 121 and the rolling body 122 form a ball bearing structure. In addition, since the bearing ring 120 and the aperture base 310 are threadedly connected by the locking pin 313, they are fixed to the external bottom device. This allows the aperture top cover 110 and the fixed layer 112 to rotate horizontally relative to the bearing ring 120 and the aperture base 310 with less wear. Since the upper limit pin 214 of the arc-shaped light-shielding sheet 211 in the light-shielding module 210 is inserted into the fixing hole 114 of the fixed layer 112, and the lower limit pin 215 is inserted into the guide groove 311 of the aperture base 310, when the fixed layer 112 rotates, one side of the arc-shaped light-shielding sheet 211 is driven to move by the upper limit pin 214, and the other side is moved along the guide groove 311 by the lower limit pin 214. The 16 stacked arc-shaped light-shielding sheets 211 move at the same time, so that the hole in the middle of the aperture through which light passes is reduced as the arc-shaped light-shielding sheet 211 moves. When the fixed layer 112 rotates in the opposite direction, the arc-shaped light-shielding sheet 211 returns to its original position, so that the hole is expanded. In this way, the width of the light column passing through is controlled.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
