Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically relating to a novel lighting system for various large aquariums. Background Technology

[0002] Aquarium lighting refers to the lighting system used in aquariums (fish tanks), and its core functions encompass two dimensions: ornamental lighting and ecological supplemental lighting. In terms of ornamental value, sufficient light makes the colors of aquatic organisms in the tank more vibrant, significantly enhancing the viewing experience. In terms of ecological benefits, light is essential for aquatic plants to perform photosynthesis, and it is also an indispensable energy source for the growth and reproduction of some fish species—appropriate light can promote fish growth, make their colors more vibrant, and shorten their breeding cycle. With the improvement of people's living standards and the booming development of the aquarium industry, the market has placed comprehensive demands on aquarium lighting equipment, including higher brightness, better spectral matching, lower energy consumption, longer lifespan, and more intelligent control methods.

[0003] Chinese Patent CN218671976U, published on March 27, 2023, discloses a universal light fixture for various large aquariums, including a retaining frame. The retaining frame has several screw holes on one side, and a clamping mechanism is provided on the inner wall of each screw hole. A fixing frame is fixedly connected above the retaining frame. A rotating shaft one and a rotating shaft two are rotatably connected to the inner wall of the fixing frame. A mounting tube is sleeved on the surface of the rotating shaft one, and an electric telescopic rod is fixedly connected to the surface of the mounting tube. When the device is in operation, water from the aquarium splashes onto the light fixture, causing water to accumulate on the surface, increasing the risk of short circuits. Furthermore, when the user turns on the light, the light shines directly into the user's eyes, causing discomfort. Additionally, when the outer wall of the aquarium is sloping, the aforementioned fixing device cannot effectively secure the fixture. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel lighting system applicable to various large aquariums, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a novel lighting fixture applicable to various large aquariums, comprising a base, two sets of fixed plates fixedly connected to the top of the base, a rotating rod rotatably connected between the two sets of fixed plates, a swing plate fixedly connected to the outer side of the rotating rod, and multiple sets of lamps mounted on the inner side of the swing plate. Sliding grooves are formed on both sides of the base, and a moving rod is slidably connected to the inner side of the base and within the two sets of sliding grooves. A threaded rod is threadedly rotatably connected to the inner side of the moving rod. A motor is mounted on the inner side of the base and within one set of sliding grooves. Mounted at the output end of the motor, the base has a fixed rod fixedly connected to the inner side of the base and to the inner side of both sets of sliding grooves. A rotating rod is rotatably connected to both sides of the moving rod. A transmission rod is rotatably connected to the outer side of both rotating rods and the fixed rod. A push rod is rotatably connected to the inner side of both sets of transmission rods. Grooves are provided on both sides of the swing plate. The push rod is slidably connected to the inner side of the swing plate and to the inner side of the groove. A transparent plastic plate is slidably connected to the bottom of the base. An extension plate is fixedly connected to the top of the transparent plastic plate. Three sets of springs are fixedly connected between the extension plate and the base.

[0006] Furthermore, the transparent plastic plate is attached to the movable rod, and the length of the transparent plastic plate is greater than the distance from the rotating rod to the end of the lamp furthest from the rotating rod.

[0007] Furthermore, the height of the extension plate is equal to the height of the base, and the three sets of springs are evenly distributed between the extension plate and the base.

[0008] Furthermore, the depth of the groove is the same as the diameter of the push rod, the height of the moving rod is the same as the height of the base, and a notch is provided above the moving rod.

[0009] Furthermore, the swing plate has two sets of openings on its outer side. A sliding plate is slidably connected to the outer side of the swing plate and the inner side of the openings. A mounting plate is fixedly connected to the outer side of the swing plate and between the two sets of sliding plates. Two sets of springs are fixedly connected between the mounting plate and the sliding plate. A moving plate is slidably connected to the upper part of the base and on both sides of the sliding plate. A guide rod is slidably connected to the inner side of the moving plate and passes through the sliding plate. A transmission rod is rotatably connected to the outer side of the sliding plate and the side near the multiple sets of lamps. A rotating rod is rotatably connected to the inner side of the two sets of transmission rods. A light-shielding plate is fixedly connected to the outer side of the rotating rod. The light-shielding plate is slidably connected to the outer side of the swing plate and on both sides of the multiple sets of lamps. Two sets of pressing plates are slidably connected to the upper part of the base and the lower part of the swing plate. A push plate is fixedly connected to the outer side of the pressing plate and the side near the moving rod.

[0010] Furthermore, the height of the light-shielding plate is the same as the thickness of the notch above the moving rod, the light-shielding plate and the notch above the moving rod are on the same vertical plane, and the length of the light-shielding plate is the same as the length of the notch above the moving rod.

[0011] Furthermore, both sides of the movable plate are provided with arc-shaped grooves, the guide rod is slidably connected to the inner side of the two sets of arc-shaped grooves, and the side of the extrusion plate near the movable plate is set as an inclined surface.

[0012] Furthermore, a movable plate is slidably connected to the lower part of the base, and a fixed plate is fixedly connected to the lower part of the base. Multiple sets of rotating screws are rotatably connected to the inner side of the movable plate. The rotating screws are rotatably connected to the outer side of the fixed plate. Two sets of extension plates are fixedly connected to the corresponding side of the movable plate and the fixed plate. Positioning rods are fixedly connected to the outer side of the two sets of extension plates. Three sets of clamping plates are rotatably connected to the outer side of the positioning rods. Multiple sets of springs are fixedly connected between the clamping plates and the movable plate and between the clamping plates and the fixed plate.

[0013] Furthermore, the multiple sets of rotating screws are all located above the multiple sets of clamping plates, and the multiple sets of springs are evenly distributed at the upper and lower ends of the multiple sets of clamping plates.

[0014] The advantages of this application are: (1) When the swing plate needs to be opened, the motor is started so that the two sets of transmission rods can drive the push rod to move upward, so that the push rod can drive the swing plate to gradually open. At the same time, the moving rod squeezes the transparent plastic plate, so that the transparent plastic plate moves towards the extension plate, so as to avoid the extension plate affecting the user's use. When the swing plate is closed, the transparent plastic plate returns to its original position through the spring, so that the transparent plastic plate can cover multiple sets of lamps and prevent the lamps from short-circuiting due to water contact.

[0015] (2) When the swing plate gradually opens, the moving rod pushes the push plate, thereby causing the squeezing plate to squeeze the moving plate. As the moving plate moves, it drives the sliding plate to move, thereby causing the light shield to move downward to block the light of multiple sets of lamps and avoid discomfort caused to the user by the light of multiple sets of lamps. When the swing plate gradually closes, the moving plate can gradually return to its original position through the second spring, thereby ending the blocking of multiple sets of lamps by the light shield and avoiding affecting the illumination of the cylinder by the lamps.

[0016] (3) When it is necessary to fix the base to the fish tank, the outer wall of the fish tank is placed between multiple sets of clamping plates. Then, the rotating screw is turned so that the movable plate gradually approaches the fixed plate. At the same time, the multiple sets of clamping plates are in contact with the inclined outer wall of the fish tank, so that the inclined outer wall of the fish tank squeezes the multiple sets of clamping plates, so that the multiple sets of clamping plates gradually tilt. After the user tightens the rotating screw, the multiple sets of clamping plates can clamp the inclined outer wall of the fish tank to fix the base. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-5 As shown, a novel lighting fixture for various large aquariums includes a base 100. Two sets of fixed plates 101 are fixedly connected to the top of the base 100. A rotating rod 102 is rotatably connected between the two sets of fixed plates 101. A swing plate 103 is fixedly connected to the outer side of the rotating rod 102. The swing plate 103 is used to cover the aquarium. Multiple sets of lights 104 are mounted on the inner side of the swing plate 103. Slide grooves 105 are provided on both sides of the base 100. A moving rod 106 is slidably connected to the inner side of the base 100 and inside the two sets of slide grooves 105. A threaded rod 107 is rotatably connected to the inner side of the base 100. A motor 108 is mounted on the inner side of the base 100 and on the inner side of a set of sliding grooves 105. The threaded rod 107 is mounted at the output end of the motor 108. A fixed rod 109 is fixedly connected to the inner side of the base 100 and on the inner side of both sets of sliding grooves 105. Rotating rods 110 are rotatably connected to both sides of the moving rod 106. Transmission rods 111 are rotatably connected to the outer sides of the rotating rods 110 and the fixed rods 109. Push rods 112 are rotatably connected to the inner sides of the two sets of transmission rods 111. By setting the push rods 112, the push rods 112 are moved upward. When in motion, the swing plate 103 can be pushed to stop the swing plate 103 from covering the fish tank. Grooves 113 are provided on both sides of the swing plate 103, the depth of which is the same as the diameter of the push rod 112. The height of the moving rod 106 is the same as the height of the base 100, and a notch is provided above the moving rod 106. The push rod 112 is slidably connected to the inside of the swing plate 103 and inside the grooves 113. A transparent plastic plate 114 is slidably connected to the bottom of the base 100. By providing the transparent plastic plate 114, multiple sets of lights 104 are shielded to prevent the lights 104 from touching the tank. Water short circuit, transparent plastic plate 114 and moving rod 106 are in contact with each other, the length of transparent plastic plate 114 is greater than the distance from rotating rod 102 to the end of lamp 104 away from rotating rod 102, an extension plate 115 is fixedly connected above transparent plastic plate 114, three sets of springs 116 are fixedly connected between extension plate 115 and base 100, by setting springs 116, transparent plastic plate 114 can be reset by springs 116, the height of extension plate 115 is equal to the height of base 100, and the three sets of springs 116 are evenly distributed between extension plate 115 and base 100.

[0021] In practical use, the above-mentioned equipment is first started by starting the motor 108, causing its output end to rotate in the forward direction. This rotation drives the threaded rod 107 to rotate. When the threaded rod 107 rotates, it drives the moving rod 106 to move along the threaded rod 107 towards the fixed rod 109. The moving rod 106 then drives the rotating rod 110 to move. The movement of the rotating rod 110 causes the transmission rod 111 to rotate, allowing the two sets of transmission rods 111 to drive the push rod 112 to move diagonally upward. This allows the push rod 112 to push the swing plate 103 to stop obstructing the fish tank. At the same time, the moving rod 106 pushes the transparent plastic plate 114, causing it to move towards the extension plate 115 to avoid... This affects the user's ability to feed the fish or clean debris in the aquarium. When the user finishes feeding the fish or cleaning debris, the output end of the motor 108 rotates in the opposite direction, causing the moving rod 106 to move along the threaded rod 107 toward the motor 108. While the swing plate 103 covers the aquarium, the moving rod 106 stops blocking the transparent plastic plate 114, allowing the spring 116 to pull the extension plate 115 toward the transparent plastic plate 114. The extension plate 115 then moves the transparent plastic plate 114 toward the motor 108, allowing the transparent plastic plate 114 to cover multiple sets of lights 104 to prevent the lights 104 from coming into contact with water and short-circuiting.

[0022] Example 2, as Figures 5-7 , Figure 1As shown, based on Embodiment 1, two sets of openings 201 are provided on the outer side of the swing plate 103. A sliding plate 202 is slidably connected to the outer side of the swing plate 103 and inside the openings 201. A mounting plate 204 is fixedly connected to the outer side of the swing plate 103 and between the two sets of sliding plates 202. Two sets of springs 203 are fixedly connected between the mounting plate 204 and the sliding plates 202. A movable plate 205 is slidably connected above the base 100 and on both sides of the sliding plates 202. A movable plate 205 allows the sliding plate 202 to swing within it, enabling the movable plate 205 and the sliding plate 202 to move together. A guide rod 206 is slidably connected to the inner side of the movable plate 205, passing through the sliding plate 202. A transmission rod 207 is rotatably connected to the outer side of the sliding plate 202, near the side of the multiple sets of lamps 104. A rotating rod 208 is rotatably connected to the inner side of the two sets of transmission rods 207. A light shield is fixedly connected to the outer side of the rotating rod 208. Plate 209, by setting a light-shielding plate 209, achieves the effect of shielding multiple sets of lamps 104. The height of the light-shielding plate 209 is the same as the thickness of the notch above the moving rod 106. The light-shielding plate 209 and the notch above the moving rod 106 are on the same vertical plane. The length of the light-shielding plate 209 is the same as the length of the notch above the moving rod 106. The light-shielding plate 209 is slidably connected to the outside of the swing plate 103 and on both sides of the multiple sets of lamps 104. The base 100 is on the upper Two sets of extrusion plates 210 are slidably connected below the swing plate 103. By setting the extrusion plates 210, the extrusion plates 210 can extrude the moving plate 205, thereby moving the moving plate 205. Arc-shaped grooves are provided on both sides of the moving plate 205. The guide rod 206 is slidably connected to the inner side of the two sets of arc-shaped grooves. The side of the extrusion plate 210 near the moving plate 205 is set as an inclined surface. A push plate 211 is fixedly connected to the outer side of the extrusion plate 210 and the side near the moving rod 106.

[0023] In practical use, when the swing plate 103 stops covering the fish tank, the moving rod 106 pushes the push plate 211, causing the push plate 211 to move towards the pressing plate 210. This push plate 211 then pushes the pressing plate 210 towards the extension plate 115, allowing the pressing plate 210 to press the moving plate 205. This causes the two sets of moving plates 205 to gradually approach each other. As the two sets of moving plates 205 approach each other, the moving plate 205 drives the sliding plate 202, causing the two sets of sliding plates 202 to gradually approach each other. This gradual approach of the two sets of sliding plates 202 causes the two sets of transmission rods 207 to swing, which in turn drives the rotating rod 208 to move towards the rotating rod 102. This allows the rotating rod 208 to drive the light-shielding plate 209 towards the rotating rod 102. The direction of 102 moves so that the light shield 209 can block the light of multiple sets of lamps 104 to prevent the light of multiple sets of lamps 104 from shining on the user and causing discomfort. When the swing plate 103 covers the fish tank again, the extension plate 115 moves towards the pressing plate 210, so that the extension plate 115 can push the pressing plate 210 towards the moving rod 106, so that the pressing plate 210 ends its blocking of the moving plate 205. The sliding plate 202 can be moved away from the two sliding plates 202 by the elastic force of the second spring 203, so that the second rotating rod 208 gradually moves away from the rotating rod 102, so that the second rotating rod 208 can drive the light shield 209 to end the blocking of multiple sets of lamps 104 to prevent the multiple sets of lamps 104 from shining on the fish tank.

[0024] Example 3, as Figures 8-9 As shown, based on Embodiment 1 or Embodiment 2, a movable plate 301 is slidably connected to the lower part of the base 100, and a fixed plate 302 is fixedly connected to the lower part of the base 100. Multiple sets of rotating screws 303 are rotatably connected to the inner side of the movable plate 301. The rotating screws 303 are rotatably connected to the outer side of the fixed plate 302. Two sets of extension plates 304 are fixedly connected to the corresponding side of the movable plate 301 and the fixed plate 302. Positioning rods 305 are fixedly connected to the outer side of the two sets of extension plates 304. Three sets of clamping plates 306 are rotatably connected to the outer side of the positioning rods 305. By setting the positioning rods 305, the clamping plates 306 are... 06 can rotate around the positioning rod 305, and multiple sets of clamping plates 306 can clamp the inclined outer wall of the fish tank. Multiple sets of springs 307 are fixedly connected between the clamping plate 306 and the movable plate 301 and between the clamping plate 306 and the fixed plate 302. By setting the springs 307, when the inclined outer wall of the fish tank presses the clamping plate 306, the clamping plate 306 can be pressed against and clamped by the force of the springs 307. Multiple sets of rotating screws 303 are all above the multiple sets of clamping plates 306, and multiple sets of springs 307 are evenly distributed at the upper and lower ends of the multiple sets of clamping plates 306.

[0025] In practical use, when encountering an inclined outer wall of the fish tank, the above-mentioned equipment moves multiple sets of clamping plates 306 to both sides of the outer wall of the fish tank. Then, by turning the rotating screw 303, the rotating screw 303 drives the movable plate 301 to move closer to the fixed plate 302. The movable plate 301 drives the extension plate 304 to move, and the extension plate 304 drives the positioning rod 305 to move. The positioning rod 305 drives the multiple sets of clamping plates 306 to move, so that the multiple sets of clamping plates 306 come into contact with the outer wall of the fish tank. Since the outer wall of the fish tank is inclined, while the clamping plates 306 are in contact with the outer wall of the fish tank, the outer wall of the fish tank squeezes the clamping plates 306, causing the clamping plates 306 to rotate until the clamping plates 306 are completely in contact with the outer wall of the fish tank. When the user fully tightens the rotating screw 303, the multiple sets of clamping plates 306 can clamp the outer wall of the fish tank through the elasticity of multiple sets of springs 307, thereby achieving the purpose of fixing the base 100.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
