Description

Technical Field

[0001] The utility model belongs to the technical field of lamps and relates to a pattern wheel component of a stage lamp. Background Art

[0002] Depending on the scene requirements, stage lighting sometimes needs to be equipped with a pattern plate on the moving head beam light. The pattern plate is equipped with pattern pieces of various patterns, so that the stage light presents a light with a pattern. The rotating pattern plate is a common component inside the moving head beam light. Driven by the motor, it illuminates the rotating pattern piece through the light, and finally presents a variety of changing forms of light and shadow effects.

[0003] For example, the patent with authorization announcement number CN207455338U discloses a new type of spotlight pattern turntable, including a pattern disk substrate, a driving gear arranged in the center of the pattern disk substrate, and a plurality of pattern gear bearing groups arranged around the driving gear and meshing with the driving gear; the pattern gear bearing group includes a pattern gear for fixing the pattern and a bearing for supporting the rotation of the pattern gear.

[0004] The bearing in the above structure can ensure the smooth rotation of the pattern gear, but there are still some shortcomings: in actual use, the stage light emits light downward and the pattern plate is set roughly horizontally as a whole. The lubricating grease in the ordinary bearing fixed to the pattern gear will leak downward from the gap between the inner and outer rings of the bearing toward the side where the pattern gear is located, resulting in a decrease in lubrication and jamming after a period of use, necessitating the entire bearing to be replaced. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a pattern wheel assembly of a stage light. The technical problem to be solved by the utility model is that the existing pattern wheel assembly has a short service life.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A pattern wheel assembly for a stage light, comprising a pattern gear and a bearing, wherein the pattern gear is annular and has a protruding sleeve portion on one side of the pattern gear, the bearing comprising an outer ring and an inner ring which can rotate relatively to each other, the inner ring being sleeved on the outer periphery of the sleeve portion, and characterized in that the end of the outer ring facing the pattern gear has an annular retaining edge arranged radially inward, a gap is left between the inner edge of the annular retaining edge and the outer peripheral surface of the inner ring, the pattern gear has an annular avoidance groove arranged around the sleeve portion, and the avoidance groove is arranged opposite to the annular retaining edge.

[0008] The pattern gear rotates synchronously with the inner ring, and the outer ring can cooperate with the surrounding components to realize the relative rotation of the pattern gear and thus realize the pattern rotation effect; by setting a radially inward annular retaining edge at one end of the outer ring facing the pattern gear, a gap is left between the inner edge of the annular retaining edge and the embedded outer peripheral surface, so that under the condition of ensuring relative rotation, the interval between the inner ring and the outer ring at this end is greatly reduced, thereby reducing the probability and speed of lubricating oil leakage, which is conducive to extending the service life; and by setting an annular avoidance groove opposite to the annular retaining edge on the pattern gear, the avoidance groove can form an interval to make way for the annular retaining edge added on the outer ring when the outer ring rotates relative to the pattern gear, thereby reducing the interference and scratching between the outer ring and the pattern gear when the outer ring rotates, thereby ensuring the service life.

[0009] In the pattern wheel assembly of the stage light, the root of the sleeve has an annular step portion, and the inner ring abuts against the step portion along the axial direction of the pattern gear, and a gap is left between the end face of the outer ring and the pattern gear. In this way, the step portion can limit the inner ring, thereby ensuring that the end face of the outer ring and the pattern gear do not directly interfere with each other, which is conducive to reducing the friction and resistance received by the outer ring when rotating relative to the pattern gear, and is conducive to ensuring the service life.

[0010] In the pattern wheel assembly of the stage light, the outer edge radius of the outer ring is larger than the outer diameter of the avoidance groove. In this way, the outer ring can effectively shield the avoidance groove, which is beneficial to prevent external dust and dirt from invading and accumulating in the avoidance groove and affecting the relative rotation of the outer ring and the pattern gear, thereby ensuring the service life.

[0011] In the pattern wheel assembly of the stage light, the outer peripheral surface of the outer ring has an annular groove arranged around the circumference, which is conducive to the axial positioning and installation of the outer ring through the cooperation of a limiting member such as a retaining spring and the annular groove.

[0012] In the pattern wheel assembly of the stage light, the pattern gear is provided with a through hole extending axially therethrough, the through hole is connected to the avoidance groove, and a columnar magnet is embedded in the through hole. This facilitates the automatic identification of the rotation position of the pattern gear by the position of the magnet for positioning during use.

[0013] In the pattern wheel assembly of the stage light, the pattern gear is made of aviation aluminum material, which greatly reduces the weight while ensuring sufficient strength, which is conducive to ensuring service life.

[0014] Compared with the prior art, the advantages of the utility model are as follows:

[0015] The pattern wheel assembly of the stage lamp can greatly reduce the speed of lubricating oil loss in the bearing through the annular retaining edge, effectively extending the service life of the entire assembly. BRIEF DESCRIPTION OF THE DRAWINGS
