Description

Combined pattern disc for stage lamp Technical Field The utility model belongs to the technical field of stage lamps, and particularly relates to a combined pattern disc for stage lamps. Background Stage lighting is also called "stage lighting", and is one of means for stage art modeling. Modern stage performance is increasingly high to stage lighting and artistic modeling's requirement, in order to strengthen the rendering effect and the infectivity of stage lighting, stage lamps and lanterns often can be equipped with pattern dish subassembly in lamps and lanterns inside and come abundant light effect. At present, pattern discs used by stage lamps are mainly divided into two types, namely a fixed pattern disc and a rotating pattern disc, and a general light-focusing stage lamp is mostly provided with one or two types of pattern discs, which have advantages, but have obvious disadvantages at the same time. The stage lamp fixing pattern disc is typically formed by fixing a plurality of patterns on the same metal plate surface through etching and other processes, wherein the patterns are circumferentially symmetrically arranged. The center of the pattern disc is provided with a rotating device taking the central shaft as the center, and the rotating device drives the whole disc to rotate taking the central shaft as the center, so that the switching among different patterns is realized. As in the prior art, chinese patent publication No. CN204593254U discloses a pattern disc for a lamp, which includes a fixed disc ring and a fixed disc core. However, the fixed pattern disc has the advantages of good temperature resistance, simple structure, large number of patterns and the like, but the fixed pattern disc also has the defects that on one hand, the pattern disc is fixed in effect and is independently used without dynamic effects such as rotation and the like, on the other hand, the pattern cannot be independently replaced, and the whole metal disc needs to be replaced when the pattern is replaced. The stage lamp rotating pattern disc generally comprises a mounting base plate, a driving gear pivoted on the base plate, and a plurality of driven gears pivoted on the mounting plate and distributed on the periphery of the driving gear. The driven gears are meshed with the driving gears, each driven gear is provided with a pattern installation base, patterns can be installed in each base, the rotary pattern disc can rotate to switch patterns like fixed patterns, pattern autorotation can be realized by driving the driven gears to rotate through central driving gear transmission, and the stage light beam autorotation dynamic effect is achieved. For example, chinese patent publication No. CN201180939Y discloses a simple detachable rotary pattern disc, in which it is also mentioned that the pattern piece is fixed in the rotary gear. Although the patterns projected by the stage lamp rotary pattern disc have dynamic and rotary effects and can be independently replaced, the stage lamp rotary pattern disc has the following defects that firstly, the structure of the pattern disc is relatively complex, the occupied space of a lamp body is relatively large, secondly, the number of patterns distributed on the pattern disc is small, and diversified selection of stage lighting effects is limited to a certain extent. Disclosure of Invention Aiming at the problems in the related art, the utility model provides a combined pattern disc for stage lamps, which is used for overcoming the technical problems in the prior art, and the utility model arranges the fixed base in the gap, so that the number of a plurality of patterns is increased on the premise of not increasing the whole space of the disc, the space utilization rate is effectively improved, and the utility model can also quickly and independently replace the fixed pattern sheet and the rotary pattern sheet. The technical scheme of the utility model is realized in such a way that the combined pattern disc for the stage lamp comprises a disc and a plurality of pattern through holes arranged on the disc, wherein the disc is provided with a central shaft; The rotary pattern disc comprises a disc, a rotary mechanism, a gear seat, a plurality of fixed pattern sheets and rotary pattern sheets, wherein the disc is provided with the fixed pattern sheets and the rotary pattern sheets at intervals, the fixed pattern sheets are arranged on the disc through the fixed base, the rotary pattern sheets are movably connected with the rotary mechanism through the gear seat, the rotary mechanism can drive the rotary pattern sheets to rotate relative to the disc, a gap is formed between two adjacent gear seats, the fixed base is arranged in the gap, the fixed pattern sheets are detachably arranged on the fixed base, and the rotary pattern sheets are detachably arranged on the gear seat. The rotary mechanism comprises a driven gear arranged on the gear seat and a driving gear meshed with the driven
