Description

Technical Field

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

[0002] A stage lighting lens is a key component of stage lighting equipment, mainly used to control and adjust the projection effect of the light. Stage lighting lenses are usually installed in front of various stage lights. It is an optical device composed of multiple lens combinations or special optical structures. The shape, material and arrangement of these lenses will vary according to different design purposes. Its main functions are focusing, diffusion, changing the beam angle and shaping the light spot shape.

[0003] In the existing technology, during the use of stage lighting lenses, the irradiation end of the stage light will continuously generate heat. However, the gap between the lens and the irradiation end is narrow and the air circulation is poor. After prolonged use, the surface temperature of the lens will rise. When the stage lighting is turned off, moisture easily adheres to the lens surface as the lens cools down naturally. This not only affects the subsequent use of stage lighting but also affects the lifespan of the lens. Utility Model Content

[0004] In view of the problems existing in the current stage lighting, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a waterproof stage lighting lens, which solves the problem that during the use of a stage lighting lens, the irradiation end of the stage light will continuously heat up, and the narrow gap between the lens and the irradiation end results in poor air circulation. After long-term use, the surface temperature of the lens will rise, and when the lens cools down naturally after the stage light is turned off, moisture will easily adhere to the surface of the lens, which will not only affect the subsequent use of the stage light, but also affect the service life of the lens.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof stage light lens includes a light housing and a stage light. The stage light is fixedly connected inside the light housing. A connecting ring is fitted at the end of the light housing. A lens is fixedly connected to the inner wall of the connecting ring. A cavity is formed inside the connecting ring. A cooling fan is fixedly connected to the inner wall of the cavity. A ventilated shell is fixedly connected to the top of the cooling fan. The ventilated shell is filled with silica gel desiccant. An air inlet groove is formed on the inner wall of the connecting ring above the cavity. A pressurized exhaust hole is formed on the inner wall of the connecting ring above the cavity. A curved exhaust hole is formed on the inner wall of the bottom end of the connecting ring. An insert plate is fixedly connected to the side wall of the connecting ring. A slot is formed on the inner wall of the light housing. The insert plate is inserted into the slot.

[0008] Preferably, the connection between the ventilated housing and the connecting ring is threaded with multiple bolts.

[0009] Preferably, a fixing rod is fixedly connected to the inner wall of the bottom end of the connecting ring at the curved exhaust hole. A baffle and a first torsion spring are movably sleeved on the wall of the fixing rod. One end of the first torsion spring is fixedly connected to the inner wall of the baffle, and the other end of the first torsion spring is fixedly connected to the inner wall of the connecting ring.

[0010] Preferably, a sealing gasket is fixedly connected to the side wall of the baffle, and the sealing gasket is pressed against the inner wall of the curved exhaust hole.

[0011] Preferably, the inner wall of the insert plate is provided with a rectangular groove, and the insert plate is rotatably connected to the inner wall of the rectangular groove. A retaining plate and a second torsion spring are fixedly sleeved on the rod wall of the rotating rod. One end of the second torsion spring is fixedly connected to the inner wall of the retaining plate, and the other end of the second torsion spring is fixedly connected to the inner wall of the insert plate. The light housing is provided with a retaining groove on the inner wall of the slot, and the retaining plate is clamped to the inner wall of the retaining groove.

[0012] Preferably, a pull rope is fixedly connected to the side wall of the card plate, and a through groove is opened on the inner wall of the connecting ring. The end of the pull rope away from the card plate passes through the through groove and is fixedly connected to a lifting seat.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. In this utility model, the connecting ring is inserted into the slot through the insert plate, which can stably set the connecting ring and the lens at the end of the light housing. Then, the cooling fan can blow the air outside the connecting ring into the interior of the ventilated housing through the air inlet groove. After being dried by silica gel desiccant, it is blown out through the pressurized exhaust hole. This can spray air onto the lens surface to improve the heat dissipation effect, while preventing water droplets from condensing and ensuring that the gap between the lens and the stage light is kept dry and clean, thus ensuring the performance of the stage light.

[0015] 2. In this utility model, gas flows through the curved exhaust hole. When the gas is compressed and placed on the surface of the baffle, the gas pressure will continue to increase and push the baffle to rotate along the wall of the fixed rod, so that the gas can be discharged. When the gas is discharged, it has a certain pressure, which can blow away some impurities and debris, and prevent impurities from accumulating at the position of the connecting ring where the baffle is located. The curved exhaust hole can prevent external water from flowing back into the interior of the connecting ring. The sealing gasket can improve the sealing effect of the baffle on the inner wall of the curved exhaust hole. The first torsion spring can facilitate the baffle to reset.

[0016] 3. In this utility model, after the insert plate is inserted into the slot, the second torsion spring can push the card plate to extend into the slot, so that the insert plate can be stably placed inside the slot. Subsequently, pulling the lifting seat can pull the pull rope to move, so that the card plate can be retracted into the rectangular slot, making it easy to pull out the insert plate and remove the connecting ring.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a waterproof stage lighting lens.

[0026] This utility model provides, for example Figure 1-4The waterproof stage light lens shown includes a light housing 1 and a stage light 2. The stage light 2 is fixedly connected inside the light housing 1. A connecting ring 3 is sleeved on the end of the light housing 1. A lens 4 is fixedly connected to the inner wall of the connecting ring 3. A cavity is opened inside the connecting ring 3. A cooling fan 5 is fixedly connected to the inner wall of the connecting ring 3 in the cavity. A ventilated housing 6 is fixedly connected to the top of the cooling fan 5. The ventilated housing 6 is filled with silica gel desiccant 7. An air inlet groove 9 is opened on the inner wall of the connecting ring 3 above the cavity. A pressurized exhaust hole 10 is opened on the inner wall of the connecting ring 3 above the cavity. A curved exhaust hole 11 is opened on the inner wall of the bottom end of the connecting ring 3. An insert plate 16 is fixedly connected to the side wall of the connecting ring 3. A slot is opened on the inner wall of the light housing 1. The insert plate 16 is inserted into the slot.

[0027] The connection between the vent housing 6 and the connecting ring 3 is connected by multiple bolts 8. The connecting ring 3 is fixedly connected to the inner wall of the bottom end of the curved exhaust hole 11 by a fixing rod 12. A baffle 13 and a first torsion spring 14 are movably sleeved on the wall of the fixing rod 12. One end of the first torsion spring 14 is fixedly connected to the inner wall of the baffle 13, and the other end of the first torsion spring 14 is fixedly connected to the inner wall of the connecting ring 3. A sealing gasket 15 is fixedly connected to the side wall of the baffle 13, and the sealing gasket 15 is pressed tightly against the inner wall of the curved exhaust hole 11.

[0028] In use, the connecting ring 3 is inserted into the slot through the insert plate 16, which allows the connecting ring 3 and the lens 4 to be stably set at the end of the light housing 1. Then, the cooling fan 5 can blow the air outside the connecting ring 3 into the interior of the ventilated housing 6 through the air inlet slot 9. After being dried by the silica gel desiccant 7, the air is blown out through the pressurized exhaust hole 10. This can spray air onto the surface of the lens 4 to improve the heat dissipation effect, while preventing water droplets from condensing. This ensures that the gap between the lens 4 and the stage light 2 remains dry and clean, thus ensuring the performance of the stage light 2.

[0029] The gas then flows through the curved exhaust hole 11. When the gas is compressed and placed on the surface of the baffle 13, the gas pressure will continue to increase and push the baffle 13 to rotate along the wall of the fixed rod 12, thereby allowing the gas to be discharged. The gas has a certain pressure when it is discharged, which can blow away some impurities and debris, and can prevent impurities from accumulating at the position of the connecting ring 3 where the baffle 13 is located. The curved exhaust hole 11 is set in a curved shape to prevent external water from flowing back into the interior of the connecting ring 3. The sealing gasket 15 can improve the sealing effect of the baffle 13 on the inner wall of the curved exhaust hole 11. The first torsion spring 14 can facilitate the reset of the baffle 13.

[0030] In order to ensure that the insert plate 16 is stably positioned inside the slot, such as Figure 1-4As shown, a rectangular groove is provided on the inner wall of the insert plate 16. A rotating rod 17 is rotatably connected to the inner wall of the insert plate 16 in the rectangular groove. A clamping plate 18 and a second torsion spring 19 are fixedly sleeved on the rod wall of the rotating rod 17. One end of the second torsion spring 19 is fixedly connected to the inner wall of the clamping plate 18, and the other end of the second torsion spring 19 is fixedly connected to the inner wall of the insert plate 16. A slot is provided on the inner wall of the slot of the light housing 1. The clamping plate 18 is clamped and set on the inner wall of the slot. A pull rope 20 is fixedly connected to the side wall of the clamping plate 18. A through groove is provided on the inner wall of the connecting ring 3. The end of the pull rope 20 away from the clamping plate 18 passes through the through groove and is fixedly connected to the lifting seat 21.

[0031] After the insert plate 16 is inserted into the slot, the second torsion spring 19 can push the card plate 18 to extend into the slot, so that the insert plate 16 can be stably placed inside the slot. Subsequently, pulling the lifting seat 21 can pull the pull rope 20 to move, so that the card plate 18 can be retracted into the rectangular slot, making it easy to pull out the insert plate 16, thereby removing the connecting ring 3.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
