Description

Technical Field

[0001] The present invention relates to the technical field of stage lamps, and more particularly to a portable waterproof case for stage lamps and a stage lamp having the same. Background Art

[0002] As people's cultural needs increase, outdoor landscape projects and outdoor live performances in the tourism industry develop rapidly, and outdoor waterproof stage moving head lights are increasingly widely used in the market. Among them, lightweight and cost control of outdoor waterproof stage lights are key technologies for achieving wider application of waterproof stage lights. In the prior art, in order to achieve a high protection level (IP65 level) and be suitable for various outdoor situations, most outdoor waterproof lamps design the base chassis into a fully sealed die-cast aluminum structure, resulting in problems such as excessively large product design volume, high cost, excessive weight, and inconvenient transportation and installation. Summary of the invention

[0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a lightweight stage light waterproof chassis and a stage light having the same, which effectively solves the problem of excessive product size, high cost and heavy weight caused by the fully sealed die-cast aluminum structure design of the base chassis of the stage lamp. On the premise of ensuring the stability and durability of the quality of the stage light chassis, the lightweight of the stage light chassis is achieved, and the manufacturing cost of the stage light is controlled within a reasonable range.

[0004] To solve the above problems, the technical solution adopted by the present invention is a lightweight stage light waterproof chassis, including a rotating shaft for controlling the rotation of the stage light, a plastic waterproof chassis cover, a top plate, a bottom plate and a side plate, the waterproof chassis cover is arranged on the bottom plate to form a cavity, the top plate and the side plates are both arranged in the chassis cavity, and the side plates connect the top plate and the bottom plate to separate the chassis cavity into a first space and a second space, the top plate is sealed and fitted with the waterproof chassis cover, the waterproof chassis cover is provided with a first connecting hole, and the top plate is provided with a second connecting hole corresponding to the first connecting hole, and one end of the rotating shaft passes through the first connecting hole and the second connecting hole in sequence and is fixed on the bearing seat in the second space.

[0005] The portable stage light waterproof case of the present invention changes the previous fully sealed die-cast aluminum structure design, and replaces the die-cast aluminum case cover with a waterproof case cover made of plastic. The waterproof case cover sealing cover is arranged on the bottom plate to form a case cavity. In order to improve the stress strength of the waterproof case cover, the waterproof case cover is sealed and connected to the top plate, and four side plates connected to the top plate and the bottom plate are arranged in the case cavity. On the one hand, the side plates provide support for the top plate and the waterproof case cover; on the other hand, the case cavity is divided into two spaces, namely the first space and the second space. The rotating shaft is arranged in the second space, and other driving components of the stage light and its control components can be arranged in the first space or the second space. Since the waterproof chassis cover is sealed and connected to the top plate and the bottom plate, the first space and the second space are both dustproof and waterproof. Moreover, since the waterproof chassis cover is made of plastic material, its weight can be greatly reduced compared with the die-cast aluminum material used in the past, so that the entire stage light chassis can be lightweight. At the same time, the plastic material also ensures that the cost of the entire stage light chassis can be controlled within a relatively low range.

[0006] Furthermore, the side panels and / or the bottom panel are made of metal materials to ensure the structural stability and stress-bearing strength of the portable stage light waterproof case.

[0007] Furthermore, the angle formed by the side plate and the bottom plate is in the range of 60° to 85°, thereby avoiding the problem that the stage light may shake or the positioning may be inaccurate due to the horizontal displacement of the top plate caused by the rotating shaft when running at high speed, thereby ensuring the structural stability of the portable waterproof stage light waterproof case.

[0008] Furthermore, a reinforcing column is included, wherein the reinforcing column is in the second space and the two ends thereof are respectively vertically connected to the top plate and the bottom plate, so as to further increase the stress strength of the top plate and the waterproof chassis cover.

[0009] Furthermore, a first waterproof pad is provided at the connection between the waterproof chassis cover and the top plate to prevent rainwater from flowing into the chassis cavity from the connection between the waterproof chassis cover and the top plate, thereby ensuring the waterproof performance of the portable stage light waterproof chassis.

[0010] Furthermore, the bearing seat is fixed on the top plate and a second waterproof pad is provided at the connection with the top plate, so as to prevent rainwater from flowing into the case cavity from the connection between the top plate and the bearing seat, thereby ensuring the waterproof performance of the portable stage light waterproof case.

[0011] Furthermore, a third waterproof pad is provided at the connection between the waterproof chassis cover and the bottom plate to prevent rainwater from flowing into the chassis cavity from the connection between the waterproof chassis cover and the bottom plate, thereby ensuring the waterproof performance of the portable stage light waterproof chassis.

[0012] Furthermore, a sealing ring is sleeved on the rotating shaft to prevent rainwater from flowing into the bearing seat from the connection between the rotating shaft and the top plate, so as to prevent the bearings and other components installed in the bearing seat from being corroded by rainwater and causing rust and failure.

[0013] Furthermore, a skeleton oil seal is sleeved on the rotating shaft to prevent dust and impurities from entering the bearing seat on the one hand, and to limit the lubricating oil in the bearing from leaking out of the bearing seat to the outside of the waterproof chassis cover on the other hand.

[0014] Furthermore, a handle is included, and a fixing seat is provided on the bottom plate in the first space, and the handle is installed on the fixing seat through a locking member that passes through the waterproof case cover. The handle can facilitate users to carry stage lighting, and the handle is installed on the bottom plate through the fixing seat, avoiding the problem that the waterproof case cover may break due to low force strength caused by directly installing the handle on the waterproof case cover.

[0015] Furthermore, a maintenance port and a sealing plate for covering the maintenance port are provided on the bottom plate, the maintenance port is communicated with the second space, and the sealing plate is sealed and connected to the bottom plate through a fourth waterproof pad. The maintenance port facilitates the later inspection and maintenance of the portable stage light waterproof case.

[0016] Furthermore, a hanging lock assembly for installing a hanging gripper is provided on one side of the bottom plate away from the waterproof chassis cover, so that the stage lamp can be hung on a mounting bracket such as a stage truss.

[0017] The present invention also provides a stage light, comprising a lamp head, a bracket and any one of the aforementioned lightweight stage light waterproof housings, wherein the lamp head is mounted on the bracket, and the bracket is connected to an end of the rotating shaft away from the first space.
