[0002] With the continuous development of modern stage design, various lighting devices for stage atmosphere creation emerge in an endless stream. These devices not only need to be able to provide light sources of various colors and brightness, but also need to have a certain waterproof function to facilitate use on various stages, especially for large-scale performances held outdoors or in humid environments. Traditional lighting devices often cannot meet the requirements, are prone to failures or low efficiency, and affect the performance effect. Therefore, it is particularly important to develop a lighting device that can effectively handle the stage atmosphere and provide waterproof protection.

[0003] Although the existing waterproof cutting lights have solved the problem of waterproofing of stage lights to a certain extent, the overall waterproof effect is still not ideal. The main problem is that a layer of sealing ring is relied on for waterproof treatment. Since a multi-segment extrusion type tight fit cannot be formed between the sealing ring and the housing, it is difficult to ensure that no moisture penetrates. This single-layer sealing method fails under high pressure or long-term use, resulting in a decline in waterproof performance. Summary of the Invention

[0006] As a preference of the above technical solution, columns are symmetrically and equidistantly embedded and installed at the bottom end of the pressing plate, a vertical plate is fixedly installed at the position inside the lifting strip at the bottom end of the column, and a return spring is arranged between the bottom end of the pressing plate and the top end of the lifting strip and located outside the column.

[0007] As a preference of the above technical solution, an extrusion plate is movably connected up and down inside the sealing cover. Extrusion columns are equidistantly installed at the top end of the extrusion plate, and the extrusion columns are slidably connected inside the sealing cover.

[0008] As a preference of the above technical solution, a diversion groove is formed inside the sealing cover. A partition plate is arranged in the middle of the diversion groove. The extrusion plate is movably installed inside the diversion groove. One end face of the extrusion plate is in mutual fit with the partition plate, and the other three sides of the extrusion plate are all in fit with the inside of the sealing cover.

[0009] As a preference of the above technical solution, rubber rings are sleeved on the outer sides of the extrusion plate and the vertical plates, and the outer sides of the vertical plates are all in fit with the inner wall of the sealing cover.

Detailed implementation manners

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Embodiment 1

[0025] The present invention provides a waterproof cutting lamp for stage atmosphere treatment, as Figures 1 to 6As shown in the figure, it includes: a base 1, a rotating seat 2 is rotatably connected to the top end of the base 1, a waterproof cutting lamp body 3 is rotatably connected inside the rotating seat 2, a sealing cover 4 is installed on the outer side of the waterproof cutting lamp body 3 by screws. The base 1 serves as the support foundation of the entire device, and the rotating seat 2 is installed at its top end in a rotatable connection manner. This rotatable connection structure enables the rotating seat 2 to rotate relative to the base 1 by a certain angle, thus facilitating the adjustment of the irradiation direction of the waterproof cutting lamp body 3. The rotatable connection structure inside the rotating seat 2 enables the waterproof cutting lamp body 3 to also rotate within a certain range, further increasing the flexibility of adjusting the lighting irradiation angle to meet the requirements of different stage scenes for the lighting direction. A waterproof groove 10 is provided at the edge of the inner wall of the sealing cover 4, a sealing gasket 11 is arranged on the inner wall of the waterproof groove 10, adhesive sheets 20 are bonded to both sides of the sealing gasket 11 and the adhesive sheets 20 are bonded inside the sealing cover 4. A lifting strip 14 is vertically movably connected inside the sealing cover 4. The number of the lifting strips 14 is set to four in total. The four lifting strips 14 are mutually attached and combined into the shape of the waterproof groove 10. A pressing plate 15 is vertically movably connected to the middle of the lifting strip 14, and side pressing plates 18 are obliquely movably connected to both sides of the lifting strip 14. The four lifting strips 14 that are vertically movably connected inside the sealing cover 4 are mutually attached and combined into the shape of the waterproof groove 10. This design enables the lifting strips 14 to closely cooperate when moving vertically to form a complete waterproof structure. The pressing plate 15 vertically movably connected to the middle of the lifting strip 14 and the side pressing plates 18 obliquely movably connected to both sides constitute a clever pressing and side pressing mechanism. By moving the pressing plate 15, the lifting strips 14 and the side pressing plates 18 can work together to effectively squeeze the sealing gasket 11, thereby further improving the waterproof effect.

[0026] As Figure 3 and Figure 5 shown, columns 16 are symmetrically and equidistantly embedded and installed at the bottom end of the pressing plate 15. A vertical plate 17 is fixedly installed at the position inside the lifting strip 14 at the bottom end of the column 16. A return spring 19 is arranged between the bottom end of the pressing plate 15 and the top end of the lifting strip 14 and at the outer side position of the column 16;

[0027] When the pressing plate 15 moves, it drives the column 16 to move. The movement of the column 16 then drives the vertical plate 17 to move. During the movement of the vertical plate 17, the gas is squeezed. At this time, the pressing plate 15 also drives the return spring 19 to be compressed. After being compressed, the return spring 19 generates a spring force. This spring force is used to squeeze the pressing plate 15 again, so that the position of the pressing plate 15 is fixed. Moreover, since heat is generated inside the waterproof cutting lamp during operation, the gas expands. Under the action of the gas expansion, the extrusion force will be indirectly increased, so that the waterproof effect of the waterproof cutting lamp is more perfect. This structural design with the cooperation of the pressing plate 15, the column 16, the vertical plate 17 and the return spring 19 makes clever use of the principle of gas expansion, further enhances the waterproof performance, and ensures the stable operation of the equipment in various environments.

[0028] As Figure 1 and Figure 3 shown, an extrusion plate 13 is movably connected up and down inside the sealing cover 4. Extrusion columns 12 are equidistantly installed at the top end of the extrusion plate 13. The extrusion columns 12 are slidably connected inside the sealing cover 4;

[0029] When the sealing cover 4 and the waterproof cutting lamp body 3 are assembled, the waterproof cutting lamp body 3 squeezes the extrusion columns 12, causing the extrusion columns 12 to move. When the extrusion columns 12 move, they push the extrusion plate 13 to move, thus changing the moving difficulty of the extrusion plate 13. This design enables the effective extrusion and guidance of the internal gas through the interaction between the extrusion columns 12 and the extrusion plate 13 during the assembly process.

[0030] As Figures 3 to 5 shown, a diversion groove is provided inside the sealing cover 4. A partition plate is arranged in the middle of the diversion groove. The extrusion plate 13 is movably installed inside the diversion groove. One end face of the extrusion plate 13 is in contact with the partition plate, and the other three sides of the extrusion plate 13 are in contact with the inside of the sealing cover 4;

[0031] The design of the diversion groove facilitates the limitation of the movement of the extrusion plate 13, ensuring that the extrusion plate 13 can operate stably along the track of the diversion groove during movement. At the same time, when the extrusion plate 13 moves, it can squeeze the gas inside the diversion groove, causing the gas to flow along the outlet part of the diversion groove, thus realizing the process of promoting gas flow. The setting of the partition plate divides the diversion groove into different areas, further guiding the gas flow direction, making the gas flow more orderly, improving the air flow organization effect inside the waterproof structure, and being conducive to maintaining the pressure balance inside the equipment, thereby enhancing the waterproof performance.

[0032] As Figures 3 to 5 shown, rubber rings are sleeved on the outer sides of both the extrusion plate 13 and the vertical plate 17. The outer sides of the vertical plates 17 are in contact with the inner wall of the sealing cover 4;

[0033] Through the elastic deformation and tight fitting of the rubber ring, the tiny gaps between the extrusion plate 13, the vertical plate 17 and the inner wall of the sealing cover 4 can be filled, ensuring that the sealing performance of the entire waterproof structure reaches the best state, and further improving the waterproof effect of the waterproof cutting lamp.

[0034] As Figures 3 to 5 shown, rounded corners are provided at the top of both the pressing plate 15 and the side pressing plate 18. The number of side pressing plates 18 is set to two in total, and the shapes of the two side pressing plates 18 are both convex;

[0035] Through the convex design, the separation of the side pressing plate 18 from the extrusion plate 13 is prevented. And under the action of the rounded corners, the cutting force of the pressing plate 15 and the side pressing plate 18 on the sealing gasket 11 is reduced, thereby preventing the problem that the pressing plate 15 and the side pressing plate 18 squeeze the inner side of the sealing gasket 11 and cause fracture or damage inside the sealing gasket 11, extending the service life of the sealing gasket 11, and ensuring the long-term stable waterproof performance of the waterproof cutting lamp.

[0036] As Figures 3 to 5 shown, a gas flow groove is provided inside the lifting strip 14. The shape of the gas flow groove is arc-shaped, and the included angle between the topmost part of the gas flow groove and the horizontal line is sixty degrees. A support strip is integrally formed inside the lifting strip 14 within the gas flow groove. The support strip is inclined, and a round hole is provided inside the support strip;

[0037] The function of the support strip is to prevent the lifting strip 14 from breaking, enhancing the structural strength and stability of the lifting strip 14. At the same time, under the action of the round hole, it does not affect the flow of gas along the inside of the lifting strip 14. This design not only ensures the structural reliability of the lifting strip 14 when bearing the pressing force and the side pressure, but also ensures the smoothness of gas flow, enabling the gas inside the waterproof structure to flow and distribute normally, which is beneficial to maintaining the pressure balance inside the equipment and further improving the waterproof effect.

[0038] As Figure 1 shown, a fixing ring 5 is fixedly installed on the outside of the waterproof cutting lamp body 3. Eight rectangular sleeves 6 are integrally formed on the outside of the fixing ring 5. A clamping strip 8 is slidably connected inside one of the rectangular sleeves 6. An installation seat 7 is sleeved outside the clamping strip 8, and an extrusion bolt 9 is threadedly connected to the top of the installation seat 7;

[0039] When the operator rotates the waterproof cutting lamp body 3, the fixing ring 5 and the rectangular sleeves 6 rotate synchronously when the waterproof cutting lamp body 3 rotates. After the rectangular sleeve 6 rotates forty-five degrees, at this time, the operator slides the clamping strip 8, and the clamping strip 8 enters the rectangular sleeve 6 along the installation seat 7, so that the angle of the waterproof cutting lamp body 3 changes. Furthermore, the angle adjustment operation of the waterproof cutting lamp body 3 is simple and convenient, and accurate angle positioning can be achieved, meeting the requirements for the light angle in different stage scenes.

[0040] As Figure 1 shown, the mounting base 7 is fixedly installed at the top of the rotating base 2, and the bottom end of the pressing bolt 9 is in mutual contact with the top end of the clamping strip 8;

[0041] Through the fixing of the rotating base 2 to the mounting base 7, and under the action of the pressing bolt 9, the clamping strip 8 can be pressed and fixed, changing the difficulty of pressing and fixing the clamping strip 8, so as to ensure that the waterproof cutting lamp body 3 can be stably maintained at the required position after adjusting the angle, and will not deviate in angle due to external force, improving the use reliability and stability of the equipment.

[0042] Working principle: Install the waterproof cutting lamp body 3 inside the rotating base 2 to ensure its stable connection with the rotating base 2 and its ability to rotate within a certain range to increase the flexibility of adjusting the lighting angle. Then place the sealing gasket 11 on the inner wall of the waterproof groove 10, and make the bonding pieces 20 on both sides of it firmly bonded to the inside of the sealing cover 4 to ensure good sealing performance. Then use screws to install the sealing cover 4 on the outside of the waterproof cutting lamp body 3. When installing the sealing cover 4, pay attention to the matching situation between the waterproof groove 10 opened on the inner wall edge of the sealing cover 4 and the waterproof cutting lamp body 3 to ensure that the waterproof groove 10 can function properly;

[0043] When the sealing cover 4 and the waterproof cutting lamp body 3 are assembled, the waterproof cutting lamp body 3 will press the extrusion column 12, causing the extrusion column 12 to move. When the extrusion column 12 moves, it pushes the extrusion plate 13 to move, thus changing the difficulty of moving the extrusion plate 13. When the extrusion plate 13 moves, it effectively squeezes the gas inside the diversion groove, causing the gas to flow along the outlet part of the diversion groove, thus realizing the process of pushing the gas to flow;

[0044] When the gas flows, it pushes the four lifting strips 14 to lift and lower. At this time, the lifting strips 14 drive the pressing plate 15 to press the sealing gasket 11, thus squeezing the middle part of the sealing gasket 11. When the pressing plate 15 is stably attached to the sealing gasket 11 and the pressing plate 15 can no longer press the sealing gasket 11, at this time, the pressing plate 15 moves under the resistance force of the waterproof cutting lamp body 3;

[0045] When the pressing plate 15 moves, it drives the column 16 to move. The movement of the column 16 further drives the vertical plate 17 to move. During the movement of the vertical plate 17, the gas is squeezed. At this time, the pressing plate 15 also drives the return spring 19 to be compressed. After the return spring 19 is compressed, it will generate a spring force. Using this spring force to squeeze the pressing plate 15 again makes the position of the pressing plate 15 remain fixed;

[0046] Moreover, since heat is generated inside the waterproof cutting lamp during operation, which causes the gas to expand, the extrusion pressure will be indirectly increased under the action of the gas expansion, thereby making the waterproof effect of the waterproof cutting lamp more perfect. Since the vertical plate 17 moves to push the gas along the gas diversion groove into the bottom end of the side pressing plate 18, at this time the gas pushes the side pressing plate 18 to move, and when the side pressing plate 18 moves, it obliquely presses the gasket 11. The movement of the pressing plate 15 can drive the side pressing plate 18 to work together to achieve multi-point pressing of the gasket 11, thereby further improving the waterproof effect.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
