Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to a fish tank lighting fixture that is leak-proof. Background Technology

[0002] Aquarium lighting fixtures typically include underwater lights and above-water lights. Underwater lights are diving lights. Existing aquarium lighting fixtures are all waterproof and moisture-proof, which makes them reliably leak-proof.

[0003] Currently, some aquarium lights use LED beads as their light-emitting element. These LED beads are mounted on a light panel, which is then housed within a lampshade. A light-transmitting cover is sealed on the front of the lampshade. When the LED beads are powered on, the light passes through the light-transmitting cover to illuminate the inside and outside of the aquarium. Because the LED light panel is typically fixed within the enclosed lampshade, replacing a damaged LED bead or a different color / wattage light panel can be difficult or impossible due to the enclosed design. This usually necessitates replacing the entire light fixture, increasing the user's costs. While some aquarium lights on the market offer replacement options for damaged light panels, removing and replacing these panels is extremely inconvenient.

[0004] Therefore, this invention proposes a fish tank lighting fixture that is leak-proof. Summary of the Invention

[0005] The purpose of this invention is to provide a leakage-proof aquarium lighting fixture in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leakage-proof aquarium lighting fixture includes a positioning rod with two sliding sleeves fitted around its exterior. A turntable connected to the back of the positioning rod is disposed between the two sliding sleeves. Two centrally symmetrical eccentric shafts are fixedly connected to the front of the turntable. The two eccentric shafts are movably connected to one side of the two sliding sleeves via connecting rods. A docking plate assembly is connected to the front of the sliding sleeves, and a lamp plate is detachably connected to the front of the docking plate assembly. A left cover and a right cover are slidably connected to both ends of the positioning rod, and the opposite ends of the left and right covers are sealed together. A transmission rod located on both sides of the turntable is fixedly connected to the inner side of the left and right covers, and the transmission rods mesh with the turntable. A light-transmitting mirror is embedded in the front of both the left and right covers.

[0008] As a further description of the above technical solution:

[0009] The docking plate assembly includes a positioning plate and a disc. One side of the positioning plate is fixedly connected to the front side of the sliding sleeve via a positioning shaft. The positioning plate has several circumferentially distributed through holes on its surface. The disc is sleeved outside the positioning shaft and the two are rotatably connected. The disc has an arc-shaped blocking hole on its surface, and one end of the arc-shaped blocking hole has an enlarged hole. The back of the lamp plate is fixedly connected to a plug shaft that is compatible with the through holes. The outer peripheral wall of the plug shaft has an annular groove near the free end.

[0010] As a further description of the above technical solution:

[0011] A support spring is fixedly connected to the middle of the front side of the positioning plate, and a limiting sleeve opposite to the support spring is fixedly connected to the back of the lamp plate.

[0012] As a further description of the above technical solution:

[0013] A rectangular insert plate is provided at one end of the left cover, and a rectangular slot that is adapted to be inserted into the rectangular insert plate is provided at one end of the right cover. A sealing gasket is nested inside the rectangular slot.

[0014] As a further description of the above technical solution:

[0015] One side of each of the two sliding sleeves is fixedly connected to an arm. One end of the arm is hinged to one side of a connecting rod via an elastic telescopic support. The arm and connecting rod connected at both ends of the elastic telescopic support are connected to different sliding sleeves.

[0016] As a further description of the above technical solution:

[0017] The elastic telescopic support includes a telescopic rod and a spring. A connecting shaft is fixedly connected to one side of the connecting rod and rotatably connected to one end of the inner rod of the telescopic rod. A connecting shaft is fixedly connected to one side of the arm and rotatably connected to one end of the outer tube of the telescopic rod. A baffle is fixedly connected to one side of the inner rod and a baffle is fixedly connected to one side of the outer tube. The baffle and the baffle are connected by a telescopic column. A spring is sleeved on the outside of the telescopic column.

[0018] As a further description of the above technical solution:

[0019] The outer tube is a through-tube structure, the connecting shaft on the connecting rod is located near the eccentric shaft, a magnetic absorbing piece is embedded on one side of the inner rod, and a magnet block opposite to the center of the turntable is fixedly connected to the front side of the positioning rod.

[0020] As a further description of the above technical solution:

[0021] A humidity sensor is fixedly connected to one side inside the right cover.

[0022] As a further description of the above technical solution:

[0023] Both sides of the left and right covers are fixedly connected to ear plates located at the mating surfaces, and the ear plates of the left and right covers are connected by screws.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, a positioning frame, a turntable, a sliding sleeve, a connecting rod, a left cover, and a right cover are provided. The front side of the sliding sleeve is detachably connected to a lamp panel via a mating plate assembly. When the lamp panel needs to be replaced, the left cover and the right cover are pulled in opposite directions to remove them. The lamp panels on the two sliding sleeves will move towards each other and disengage from the inner cavities of the corresponding left cover and right cover. This arrangement makes the lamp panel replacement operation more convenient and quick.

[0026] 2. In this invention, an elastic telescopic support is provided, which is movably connected to the arm on the connecting rod and the sliding sleeve. The elastic telescopic support applies an elastic thrust to both the sliding sleeve and the connecting rod. This elastic thrust makes the sliding of the sliding sleeve, the swing of the connecting rod, and the rotation of the turntable smoother. Here, "smooth" specifically means that there is no jamming. This design prevents the lamp panel from shaking when the lamp panel is replaced, thus improving the safety of lamp panel replacement.

[0027] 3. In this invention, magnetic absorbing sheets and magnetic blocks are provided. After the left and right covers are pulled apart in opposite directions, the magnetic blocks limit the elastic telescopic support by adsorbing the magnetic absorbing sheets, so that the elastic telescopic support can apply a reliable rotational thrust to the turntable. This rotational thrust makes the left and right covers stay stably after being separated, further improving the convenience of lamp panel replacement. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1-11A leakage-proof aquarium lighting fixture, which is submersible, includes a positioning rod 1. Two sliding sleeves 2 are fitted around the positioning rod 1, and the sliding sleeves 2 and the positioning rod 1 are slidably connected. A turntable 3 connected to the back of the positioning rod 1 is provided between the two sliding sleeves 2. Specifically, a support shaft is fixedly provided in the middle of the back of the positioning rod 1, and a sleeve fitted around the support shaft is fixedly provided in the middle of the turntable 3. The sleeve and the support shaft are rotatably connected.

[0044] Two centrally symmetrical eccentric shafts 31 are fixedly connected to the front of the turntable 3. The two eccentric shafts 31 are movably connected to one side of the two sliding sleeves 2 through the connecting rods 4 respectively. When the turntable 3 rotates, the two sliding sleeves 2 can be driven to slide along the positioning rod 1 through the two connecting rods 4 respectively. The sliding directions of the two sliding sleeves 2 are synchronously opposite and opposite, and the sliding sleeves 2 can slide to the position in front of the front of the turntable 3.

[0045] Among them, the sliding sleeve 2 is connected to the docking plate group 5 on the front side, and the docking plate group 5 is detachably connected to the lamp plate 6 on the front side. The lamp plate 6 is equipped with LED lamp beads. When the sliding sleeve 2 slides along the positioning rod 1, it can drive the lamp plate 6 to move together. The detachable structure of the lamp plate 6 makes the lamp plate 6 easy to replace.

[0046] The positioning rod 1 has a left cover 7 and a right cover 8 slidably connected to its two ends. Specifically, the bottom walls of the left cover 7 and the right cover 8 are fixedly connected to guide rods fitted onto both ends of the positioning rod 1. Specifically, sliding holes are provided at both ends of the guide rods for slidable connection. Both the left cover 7 and the right cover 8 are square shell structures with one open end. The open ends of the left cover 7 and the right cover 8 face each other, and the opposite ends of the left cover 7 and the right cover 8 are sealed together. After the left cover 7 and the right cover 8 are sealed together, they form a waterproof and moisture-proof space. Meanwhile, the turntable 3, the positioning rod, the sliding sleeve 2, and the light... All structures, including plate 6, are located within the aforementioned waterproof and moisture-proof space. Specifically, one end of the left cover 7 has a rectangular insert plate 71, and one end of the right cover 8 has a rectangular slot 81 that fits into the rectangular insert plate 71. A sealing gasket 106 is nested inside the rectangular insert plate 71. The sealing gasket 106 is a common rubber ring with good water and moisture isolation properties. When the rectangular insert plate 71 is inserted into the rectangular slot 81 and the sealing gasket 106 is compressed, the left and right covers 7 and 8 form a waterproof and moisture-proof space, thus providing the lamp with leakage protection. The inner sides of the left and right covers 7 and 8 are fixedly connected to transmission rods 9 located on both sides of the turntable 3. The transmission rods 9 mesh with the turntable 3. Specifically, a ring of teeth is fixedly provided on the outer circumference of the turntable 3, and a groove is provided on one side of the transmission rod 9 to mesh with the teeth. When the turntable 3 rotates, the meshing action drives the left and right covers 7 and 8 to move synchronously in opposite directions. A guide plate can be provided on one side of the transmission rod 9, and the opposite sides of the left cover 7 and the right cover 8 are fixedly connected to one end of the corresponding guide plate. At the same time, slides adapted to the sliding of the corresponding guide plates are opened on the opposite sides of the left cover 7 and the right cover 8, in order to further improve the smoothness of the sliding of the left cover 7 and the right cover 8.

[0047] In summary, during the process of controlling the left cover 7 and the right cover 8 to move in opposite directions to separate, the turntable 3 will be driven to rotate. When the turntable 3 rotates, it will drive the two sliding sleeves 2 to move in opposite directions through the connecting rod 4. At this time, the two sliding sleeves 2 moving in opposite directions will drive the lamp plate 6 to move closer to the axis of the turntable 3. At the same time, the lamp plate 6 will leave the inner cavity of the corresponding left cover 7 and right cover 8. At this time, the operable space around the lamp plate 6 will increase, making it easier to replace and handle.

[0048] In this embodiment, the docking plate assembly 5 includes a positioning plate 51 and a disc 52. One side of the positioning plate 51 is fixedly connected to the front side of the sliding sleeve 2 via a positioning shaft 511. The surface of the positioning plate 51 has several circumferentially distributed through holes 512. In this embodiment, there are three through holes 512. The disc 52 is sleeved on the outside of the positioning shaft 511 and the two are rotatably connected. The surface of the disc 52 has an arc-shaped blocking hole 521. One end of the arc-shaped blocking hole 521 has an enlarged hole 5211. The diameter of the enlarged hole 5211 is larger than that of the arc-shaped blocking hole 5211. The back of the lamp panel 6 is fixedly connected with a shaft 61 that is compatible with the through hole 512. The number of shafts 61 is the same as the number of through holes 512 and they correspond one-to-one. The outer peripheral wall of the shaft 61 is provided with an annular groove 611 near the free end. The diameter of the bottom circle of the annular groove 611 is less than or equal to the width of the arc-shaped stop hole 521. After the shaft 61 passes through the through hole 512 and the enlarged hole 5211, when the disc 52 is rotated, the arc-shaped stop hole 521 will enter the annular groove 611. As a result, the disc 52 will limit the shaft 61, and thus limit the lamp panel 6.

[0049] Furthermore, a support spring 513 is fixedly connected to the middle of the front side of the positioning disk 51, and a limiting sleeve 62 opposite to the support spring 513 is fixedly connected to the back of the lamp plate 6. After the lamp plate 6 and the positioning disk 51 are connected, the support spring 513 will exert an elastic thrust on the lamp plate 6 for a period of time. This elastic thrust prevents the lamp plate 6 from shaking.

[0050] Both the left cover 7 and the right cover 8 have a light-transmitting mirror 108 embedded in their front surfaces. Specifically, the front surfaces of the left cover 7 and the right cover 8 have circular holes, and the light-transmitting mirror 108 is installed inside these holes using sealant. The light-transmitting mirror 108 reflects the light emitted by the LED beads on the lamp panel 6, thus increasing the illumination range of the lamp. It should be noted that when the left cover 7 and the right cover 8 are joined and sealed, the lamp panel 6 will be located behind the corresponding light-transmitting mirror 108.

[0051] In this embodiment, one side of each of the two sliding sleeves 2 is fixedly connected to an arm 21. One end of the arm 21 is hinged to one side of the connecting rod 4 via an elastic telescopic rod support 101. The arm 21 and the connecting rod 4 connected at both ends of the elastic telescopic rod support 101 are connected to different sliding sleeves 2. The elastic telescopic rod support 101 indirectly applies a circumferential rotational thrust to the turntable 3 through the connecting rod 4. This thrust causes the turntable 3 to rotate, which in turn drives the left cover 7 and the right cover 8 to move in opposite directions, causing the left cover 7 and the right cover 8 to press against each other, making the insertion operation of the left cover 7 and the right cover 8 smoother. At the same time, the connecting rod 4 is also subjected to the elastic thrust of the elastic telescopic rod support 101, so that the connecting rod 4 and the sliding sleeve 2 will not shake randomly, making the sliding of the sliding sleeve 2 smoother. In other words, the setting of the elastic telescopic rod support 101 makes the movement of the movable parts on the positioning rod 1 smoother.

[0052] Specifically, the elastic telescopic support 101 includes a telescopic rod 1011 and a spring 1012. A connecting shaft 41 is fixedly connected to one side of the connecting rod 4 and rotatably connected to one end of the inner rod 10112 of the telescopic rod 1011. A connecting shaft 211 is fixedly connected to one side of the arm 21 and rotatably connected to one end of the outer tube 10111 of the telescopic rod 1011. The inner rod 10112 is sleeved inside the outer tube 10111, and the inner rod 10112 and the outer tube 10111 are slidably connected. A second baffle 101121 is fixedly connected to one side of the inner rod 10112, and a first baffle 101111 is fixedly connected to one side of the outer tube 10111. The first baffle 101111 and the second baffle 101121 are connected by a telescopic column 102. The telescopic column 102 is a two-section telescopic structure. A spring 1012 is sleeved on the outside of the telescopic column 102. The spring 1012 allows the telescopic rod 1011 to extend through the first baffle 101111 and the second baffle 101121.

[0053] Furthermore, the outer tube 10111 has a through-tube structure, and the inner rod 10112 can pass through the outer tube 10111 when it moves. The connecting shaft 41 on the connecting rod 4 is set close to the eccentric shaft 31. A magnetic absorbing piece 103 is embedded on one side of the inner rod 10112. A magnet block 104 opposite to the center of the turntable 3 is fixedly connected to the front side of the positioning rod 1. When the left cover 7 and the right cover 8 are separated to the maximum distance between them, the elastic telescopic rod support 101 is in the maximum compression state and will also change its orientation. After changing its orientation, it will apply a reverse rotation thrust to the turntable 3. This thrust allows the left cover 7 and the right cover 8 to be unfolded and in a stable state, which is convenient for manual disassembly and assembly of the lamp panel 6. When the magnet block 104 and the magnetic absorbing piece 103 are magnetically connected, they can effectively prevent the elastic telescopic rod support 101 from swinging back.

[0054] In this embodiment, a humidity sensor 105 is fixedly connected to one side inside the right cover 8. The humidity sensor 105 is used to monitor the humidity of the waterproof and moisture-proof space in real time. In use, a cable sleeve is installed on the rear wall of the left cover 7. One end of the cable passes through the cable sleeve and enters the waterproof and moisture-proof space. One end of the cable is provided with a plug. The light board 6 is connected to the plug and the plug is plugged into a matching electrical socket. The other end of the cable is connected to a plug. A control adapter is connected in series on the cable. The control adapter is provided with buttons, a display screen and a buzzer. The control circuit board in the controller is electrically connected to the humidity sensor 105. The display screen shows the humidity inside the waterproof and moisture-proof space. When the humidity is greater than the safe humidity, the buzzer sounds an alarm.

[0055] In this embodiment, ear plates 107 located at the mating surface are fixedly connected to both sides of the left cover 7 and the right cover 8. The ear plates 107 of the left cover 7 and the right cover 8 are connected by screws. In specific implementation, threaded holes are opened on the ear plates 107 on the left cover 7, and through holes are opened on the ear plates 107 on the right cover 8 opposite to the threaded holes. Connecting the two ear plates 107 with screws can improve the connection strength between the left cover 7 and the right cover 8.

[0056] In this embodiment, an L-shaped plate can be fixedly installed on the rear wall of the left cover 7. Two suction cups are provided on the back of the L-shaped plate to facilitate the adsorption of the lamp onto the aquarium wall.

[0057] Working principle: When using the lamp panel 6, first remove the lamp from the fish tank. Then, use a tool to unscrew the screws connecting the two ear plates 107. Next, manually pull the right cover 8 and the left cover 7 in opposite directions. During the separation of the right cover 8 and the left cover 7, the turntable 3 will rotate relative to the positioning rod 1 through their respective connected transmission rods 9. When the turntable 3 rotates, it will pull the two sliding sleeves 2 in opposite directions through the connecting rod 4, thereby driving the two lamp panels 6 to move in opposite directions. During this process, the connecting rod 4 will compress the elastic telescopic support 101 and simultaneously compress the elastic telescopic support 101. The telescopic rod 101 will change angle. When the magnet block 104 and the magnetic plate 103 are attached, they are magnetically attracted, and the telescopic rod 101 cannot swing. At the same time, it uses elasticity to prevent the turntable 3 from rotating. At this time, manually first separate the plug on the electrical connection on the lamp board 6 from the plug on the cable, and then manually rotate the disc 52 to make the enlarged hole 5211 enter the annular groove 611. At this time, the lamp board 6 can be easily pulled out, and then a new lamp board 6 can be replaced. After reversing the above operation steps, the right cover 8 and the left cover 7 can move in opposite directions and close again.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
