Description

Technical Field

[0001] This utility model relates to the field of stage lighting, specifically to a waterproof sealing structure for stage lighting. Background Technology

[0002] Stage lights, as lighting devices used on stage, serve to provide lighting effects and create atmosphere.

[0003] Existing stage lights generally employ a sealed structure, allowing the lighting components, circuit boards, and wiring to fit seamlessly into the sealed structure. However, the sealing performance of existing stage lights is relatively poor, allowing water droplets to easily enter the lamp body and cause malfunctions. Although some companies have improved the sealing structure to enhance its sealing performance, the cost is high and cannot meet the industry's stringent requirements. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof sealing structure for stage lights, which can improve the sealing effect and reduce costs.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A waterproof sealing structure for a stage light includes a support frame, a baffle, and an elastic seal. The elastic seal is circumferentially rotating, with one end forming a first end and the other end forming a second end. The support frame has a mounting hole, and the elastic seal is embedded in the mounting hole. The circumferential wall of the elastic seal abuts against the side wall of the mounting hole. The first end of the elastic seal is located inside the mounting hole and abuts against the hole wall. The baffle is detachably connected to the support frame. The second end of the elastic seal is located outside the mounting hole and abuts against the baffle. The elastic seal has a through hole for a power supply line, which passes through both the first and second ends of the elastic seal.

[0007] The elastic seal is conical, and the diameter of the first end of the elastic seal is smaller than the diameter of the second end.

[0008] The mounting hole includes a first hole segment and a second hole segment; the first hole segment and the second hole segment are arranged sequentially along the direction away from the baffle, and the diameter of the second hole segment is smaller than the diameter of the first hole segment.

[0009] The first end of the elastic seal abuts against the wall of the hole at the end of the first hole section away from the baffle.

[0010] The elastic sealing element is a silicone ring.

[0011] The baffle is provided with a through hole directly opposite the wire hole.

[0012] One end of the baffle is provided with a first connecting part, and the other end is provided with a second connecting part. The first connecting part is detachably connected to the support frame, and the second connecting part is detachably connected to the support frame.

[0013] The first connecting part and the second connecting part are located on both sides of the through hole.

[0014] The first connecting part is connected to the support frame via a first locking member, and the second connecting part is connected to the support frame via a second connecting member.

[0015] The elastic seal has several through holes around its axis for power supply lines to pass through.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a waterproof sealing structure for a stage light. It combines a support frame, a baffle, and an elastic seal. The circumferential wall of the elastic seal is in contact with the side wall of the mounting hole, while the first end of the elastic seal abuts against the wall of the mounting hole, and the second end of the elastic seal abuts against the baffle. When the wire is threaded through the hole, the side wall of the mounting hole restricts the outward expansion of the elastic seal, forcing the wall of the mounting hole to contract inward, thus ensuring a tight seal between the wire hole and the wall of the mounting hole. This improves the sealing effect between the wall of the mounting hole and the wire. Moreover, the structure is simple, easy to manufacture, and reduces costs. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] like Figure 1-4 As shown, a waterproof sealing structure for a stage light includes a support frame 10, a baffle 20, and an elastic sealing element 30. The elastic sealing element 30 is in the shape of a circumferential rotating body, with one end of the elastic sealing element 30 forming a first end 31 and the other end forming a second end 32. The support frame 10 is provided with a mounting hole 40, and the elastic sealing element 30 is embedded in the mounting hole 40. The circumferential wall of the elastic sealing element 30 abuts against the side wall of the mounting hole 40. The first end 31 of the elastic sealing element 30 is located inside the mounting hole 40 and abuts against the wall of the mounting hole 40. The baffle 20 is detachably connected to the support frame 10. The second end 32 of the elastic sealing element 30 is located outside the mounting hole 40 and abuts against the baffle 20. The elastic sealing element 30 is provided with a wire hole 50 for a power supply line to pass through, and the wire hole 50 passes through the first end 31 and the second end 32 of the elastic sealing element 30.

[0025] This utility model provides a waterproof sealing structure for a stage lamp. It combines a support frame 10, a baffle 20, and an elastic sealing element 30. The circumferential wall of the elastic sealing element 30 abuts against the side wall of the mounting hole 40. Simultaneously, the first end 31 of the elastic sealing element 30 abuts against the wall of the mounting hole 40, and the second end 32 abuts against the baffle 20. When a wire is threaded through the wire hole 50, the side wall of the mounting hole 40 restricts the radial outward expansion of the elastic sealing element 30, forcing the wall of the wire hole 50 to contract inward, ensuring a tight fit between the wire hole and the wall of the wire hole 50. This improves the sealing effect between the wall of the wire hole 50 and the wire. Furthermore, by rationally setting the cooperation relationship between the support frame 10, the baffle 20, and the elastic sealing element 30, the structure is simple, the sealing effect is improved, manufacturing and assembly are convenient, and costs are reduced.

[0026] The elastic seal 30 is conical in shape, and the diameter of the first end 31 of the elastic seal 30 is smaller than the diameter of the second end 32, so as to increase the contact area between the elastic seal 30 and the mounting hole 40 and improve the compression resilience.

[0027] The mounting hole 40 includes a first hole segment 41 and a second hole segment 42; the first hole segment 41 and the second hole segment 42 are arranged sequentially along the direction away from the baffle 20, and the diameter of the second hole segment 42 is smaller than the diameter of the first hole segment 41. The first end 31 of the elastic seal 30 abuts against the hole wall of the end of the first hole segment 41 away from the baffle 20. By adopting a two-section hole design with decreasing diameter in the mounting hole 40, an axial limiting effect is formed on the elastic seal 30, preventing displacement of the elastic seal 30 under pressure, improving the installation stability of the elastic seal 30, and facilitating manufacturing.

[0028] The elastic seal 30 is a silicone ring. By using a silicone ring for the elastic seal 30, the silicone ring can withstand high and low temperatures, resist aging, and has good elasticity, thus adapting to the temperature changes and long-term compression environment caused by the frequent use of stage lights, and always maintaining good sealing performance and physical stability.

[0029] In addition, the elastic seal 30 can be any existing seal on the market, but using a silicone ring for the elastic seal 30 is the most preferred embodiment of this utility model, which is beneficial to maintaining good sealing performance and physical stability and extending service life.

[0030] The baffle 20 is provided with a through hole 60 directly opposite the wire hole 50. During wire installation, the wire passes through the through hole 60 and is installed in the wire hole 50 and the second hole section 42.

[0031] The elastic seal 30 has a plurality of through holes 50 for power supply wires to pass through around its axis. The design of multiple through holes 50 allows multiple wires to be sealed together through the same elastic seal 30, reducing the number of elastic seals 30, simplifying the overall assembly complexity, reducing the risk of weak waterproofing caused by the dispersion of multiple holes, improving waterproofing efficiency, and further reducing costs.

[0032] The baffle 20 has a first connecting portion 21 at one end and a second connecting portion 22 at the other end. The first connecting portion 21 is detachably connected to the support frame 10, and the second connecting portion 22 is detachably connected to the support frame 10. The first connecting portion 21 and the second connecting portion 22 are located on opposite sides of the through hole 60. By using the first connecting portion 21 and the second connecting portion 22 to detachably connect the baffle 20 to the support frame 10, the stress on the baffle 20 can be distributed, preventing deformation of the baffle 20 due to local stress concentration. Simultaneously, it supports quick assembly and disassembly of the baffle 20, facilitating maintenance or replacement of the baffle 20.

[0033] The first connecting part 21 is connected to the support frame 10 via a first locking member, and the second connecting part 22 is connected to the support frame 10 via a second connecting member. The first connecting part 21 has a first through hole 71, and the support frame 10 has a first threaded hole 72. The first locking member is a first locking screw, which passes through the first through hole 71 and is threadedly connected to the first threaded hole 72. The second connecting part 22 has a second through hole 73, and the support frame 10 has a second threaded hole 74. The second locking member is a second locking screw, which passes through the second through hole 73 and is threadedly connected to the second threaded hole 74. This structure facilitates the assembly and disassembly of the baffle 20 and reduces assembly costs.

[0034] The baffle 20 includes a central portion located between the first connecting portion 21 and the second connecting portion 22. A through hole 60 is disposed on the central portion. The width of the first connecting portion 21 gradually decreases from one end near the central portion to the section away from the central portion. Similarly, the width of the second connecting portion 22 gradually decreases from one end near the central portion to the section away from the central portion. By adopting the above structure for the baffle 20, the connection of the baffle 20 can be facilitated, while the material used for the baffle 20 can be reduced, thus lowering the manufacturing cost of the baffle 20.

[0035] The support frame 10 includes a frame body and a boss 11 disposed on the frame body and protruding relative to the frame body. The first threaded hole 72 and the second threaded hole 74 are both disposed on the boss 11. The mounting hole 40 is disposed on the boss 11 and extends to the frame body. The second end 32 of the elastic seal 30 is spaced apart from the end of the boss 11 near the baffle 20, and the second end 32 of the elastic seal 30 protrudes relative to the boss 11 toward the direction near the baffle 20.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
