TECHNICAL FIELD

[0001] The utility model relates to the technical field of stage lamp, more particularly to a lens seat compatible with multiple sizes of lenses and a stage lamp with the same. BACKGROUND

[0002] In the optical system of stage light, the waterproof sealing performance at the light-emitting lens directly affects the reliability and service life of the lamp in humid, dusty and other harsh environments. For the fixed installation method of the light-emitting lens, as described in the invention CN111750301B, "the lamp barrel further comprises a top cover, the top cover is sleeved on the top of the light-emitting lens fixing seat, and is fixedly connected with the light-emitting lens fixing seat". In the mainstream scheme of the current industry, in order to further improve the waterproof performance, a complete waterproof rubber strip is usually arranged between the light-emitting lens and the fixing seat. Under the bearing of the annular top cover, the waterproof rubber strip deforms to fill the gap between the light-emitting port and the lens, so as to achieve good waterproof effect.

[0003] Although the above scheme can realize basic waterproof, its inherent defects significantly restrict the product competitiveness. For example, the lens sizes matched by each lamp type are not the same, at this time, the top cover or the compression ring of the corresponding size needs to be redesigned to cooperate with the fixing seat, the cost is difficult to reduce, and the compatibility is insufficient. At the same time, the machining precision of the whole top cover or compression ring is high, which increases the material cost, and the matching tolerance control between the top cover or compression ring and the lens is difficult. In addition, such structure needs to uniformly tighten multiple bolts or rotate the whole thread when installing, which is time-consuming and laborious. UTILITY MODEL CONTENTS

[0004] The utility model provides a lens seat compatible with multiple sizes of lenses and a stage lamp with the same to overcome at least one of the defects of the prior art, which can install lenses of multiple sizes and solve the problem of complex lens seat structure that is difficult to disassemble and assemble conveniently.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of a lens seat compatible with multiple sizes of lenses and a stage lamp with the same, wherein the lens seat compatible with multiple sizes of lenses comprises an annular fixing seat for installing a lens, a plurality of installation columns arranged around the periphery of the fixing seat, a sealing strip located between the lens and the fixing seat, and a compression plate detachably installed on the installation column, the compression plate has a connecting end and an abutting portion, when the lens is placed on the fixing seat, the connecting end of the compression plate is connected with the installation column, so that the abutting portion of the compression plate abuts against the lens and clamps the lens together with the fixing seat.

[0006] By placing the lens in the fixed seat, and then connecting the pressing plate with the fixed column, the pressing part of the pressing plate applies a pressing force to the lens towards the fixed seat, so that it is closely attached to the fixed seat. At the same time, the sealing strip between the lens and the fixed seat is squeezed and fills the gap between them, ensuring good waterproof and dustproof performance.

The addition of the elastic member can absorb and reduce the vibration and impact between the pressing part and the lens, and protect the lens surface from scratching. At the same time, the elastic member can compensate for the size error of the mounting column or the pressing plate during manufacturing or installation, ensuring that the pressing plate can more closely press the lens.

[0008] Further, the elastic member has a clamping groove for accommodating the pressing part. By clamping the elastic member on the pressing part to press the lens, the elastic member can avoid misalignment during installation, and the installation method is more convenient.

[0009] Further, the end of the pressing plate forms the connecting end, the side close to the lens forms the pressing part, and the elastic member is clamped and fixed on the pressing plate. The elastic member can be stably clamped on the pressing part and is not easy to come off, improving the stability of the connection and the positioning accuracy of the installation.
