[0038] See also Figure 1 Now, the underwater lamp 10 provided in the embodiment of the present application is described. The underwater lamp 10 comprises:

[0039] The gland 2 comprises a first clamping block 21, wherein the first clamping block 21 has a first clamping surface 211;

[0040] The bottom shell 6 includes a second clamping block 61, and the second clamping block 61 has a second clamping surface 611. The pressure cover 2 and the bottom shell 6 are arranged along the first direction, and the pressure cover 2 and the bottom shell 6 can rotate relatively along the first rotation direction so that the first clamping surface 211 moves along the second clamping surface 611 until the first clamping block 21 forms a limit block on the second clamping block 61 in the first direction, so that the pressure cover 2 and the bottom shell 6 are in a clamping state;

[0041] A first waterproof member 4 is provided between the gland 2 and the bottom shell 6;

[0042] Among them, at least one of the first clamping surface 211 and the second clamping surface 611 is an inclined surface relative to the first direction, so that the first clamping surface 211 moves along the second clamping surface 611 in the first direction to produce relative displacement, forcing the pressure cover 2 and the bottom shell 6 to rotate relative to each other in the first rotation direction and press the first waterproof part 4.

[0043] The gland 2 and the bottom shell 6 in this embodiment are both part of the shell of the underwater lamp 10. The connection between the gland 2 and the bottom shell 6 provides a closed waterproof space for the internal structure of the underwater lamp 10. The light source assembly is arranged in the gland 2 and the bottom shell 6. The light source assembly may include various lamp beads, bulbs and their corresponding drive parts. Figure 1 In the illustrated embodiment, the LED light source lamp board 51 and its power driver 52 are installed in the pressure cover 2 and the bottom shell 6 .

[0044] The pressure cover 2 may include a light-transmitting portion itself, or may be provided with an independent light-transmitting panel so that the light emitted by the internal light source assembly can be transmitted. Figure 1 In the embodiment shown, a transparent cover 3 is provided separately, and a window is provided in the middle of the pressure cover 2, and the transparent cover 3 is installed in the pressure cover 2 corresponding to the window. The bottom shell 6 usually does not need to be made of a light-transmitting material, but in some scenarios where the bottom shell 6 needs to be light-transmitting, a light-transmitting material can also be used. The first waterproof component 4 can be made of rubber, silicone and other materials. The first waterproof component 4 is installed between the pressure cover 2 and the bottom shell 6 to prevent water from entering the connection between the pressure cover 2 and the bottom shell 6. The first waterproof component 4 can be an independent waterproof pad, or it can be a flexible structure attached to the pressure cover 2 or the bottom shell 6, and its shape is determined according to the shape of the connection between the pressure cover 2 and the bottom shell 6. In the example Figure 1 In the embodiment shown, the first waterproof member 4 adopts a relatively common waterproof gasket.

[0045] The connection between the gland 2 and the bottom shell 6 of this embodiment is a snap connection. Specifically, a first clamping block 21 is provided on the gland 2, and a second clamping block 61 is provided on the bottom shell 6. When the gland 2 and the bottom shell 6 rotate relative to each other along the first rotation direction, the first clamping surface 211 moves along the second clamping surface 611 to the snap connection position. At the snap connection position, the first clamping block 21 and the second clamping block 61 form a limit block in the first direction to snap the gland 2 and the bottom shell 6, that is, the first clamping block 21 and the second clamping block 61 block each other in the arrangement direction of the gland 2 and the bottom shell 6, so that the gland 2 and the bottom shell 6 will not be separated. The number of the first clamping block 21 and the second clamping block 61 can be one group or multiple groups. The more groups, the higher the stability. If the first clamping block 21 and the second clamping block 61 are multiple groups, it is best to evenly distribute them along the circumferential direction of rotation, so as to ensure that the force of the connection between the gland 2 and the bottom shell 6 is uniform. When connecting the pressure cover 2 and the bottom shell 6, the pressure cover 2 and the bottom shell 6 can be relatively rotated in a first rotation direction, so that the first clamping block 21 and the second clamping block 61 are rotated to block each other to achieve clamping; when disassembling the pressure cover 2 and the bottom shell 6, the pressure cover 2 and the bottom shell 6 can be relatively rotated in a second rotation direction opposite to the first rotation direction, so that the first clamping block 21 and the second clamping block 61 are relatively separated, thereby achieving disassembly of the pressure cover 2 and the bottom shell 6.

[0046] At least one of the first clamping surface 211 and the second clamping surface 611 is an inclined surface relative to the first direction. Specifically, the first clamping surface 211 can be an inclined surface, the second clamping surface 611 can be an inclined surface, or both the first clamping surface 211 and the second clamping surface 611 can be inclined surfaces. In either case, the first clamping block 21 and the second clamping block 61 can be relatively moved in the first direction under the action of the inclined surface, thereby driving the pressure cover 2 and the bottom shell 6 to approach each other, pressing the first waterproof component 4, and thus improving the waterproof performance of the underwater lamp 10.

[0047] Compared with the existing integrated underwater lamps 10, the present application is more conducive to the production and assembly of lamps. Compared with the underwater lamps 10 connected by screws, not only can the connection prevent the shell from breaking due to uneven screw force, effectively improving the waterproof performance, but also it is more convenient to operate. Compared with the underwater lamps 10 connected by glue, it is not prone to aging and leakage problems, and will not affect the water environment due to gluing.

[0048] See also Figure 1 In one embodiment of the present application, the underwater lamp 10 also includes a locking member 1, which is connected between the pressure cover 2 and the bottom shell 6 and is used to prevent the pressure cover 2 and the bottom shell 6 from rotating relative to each other when the pressure cover 2 and the bottom shell 6 are in a snap-fit ​​state.

[0049] Since the gland 2 and the bottom shell 6 in the underwater lamp 10 of this embodiment are connected and disassembled by relative rotation, a locking member 1 is provided in this embodiment to block the gland 2 and the bottom shell 6 from rotating relative to each other when the gland 2 and the bottom shell 6 are connected, so as to prevent the gland 2 and the bottom shell 6 from being separated from each other. The locking member 1 can be a corresponding concave-convex structure provided on the first clamping block 21 and the second clamping block 61. When the first clamping block 21 and the second clamping block 61 are rotated to the connected position, the concave-convex structures are engaged with each other, so as to prevent the two from rotating relative to each other. The locking member 1 can also be a pin or a screw structure, which is inserted between the gland 2 and the bottom shell 6 to prevent the two from rotating relative to each other. Regardless of the method used by the locking member 1, as long as it can block the gland 2 and the bottom shell 6 from rotating relative to each other, the gland 2 and the bottom shell 6 can be kept in the connected state.

[0050] In one embodiment of the present application, the locking member 1 includes a locking column 11, the pressure cover 2 is provided with a first locking hole 22, and the bottom shell 6 is provided with a second locking hole. When the pressure cover 2 and the bottom shell 6 are in a clamped state, the locking column 11 is inserted into the first locking hole 22 and the second locking hole.

[0051] See also Figure 1 In this embodiment, the locking member 1 adopts a locking column 11, and the position of the locking column 11 is determined according to the positions of the first locking hole 22 on the gland 2 and the second locking hole on the bottom shell 6. The positions of the first locking hole 22 and the second locking hole only need to ensure that the locking column 11 can pass through both at the same time. Generally speaking, the first locking hole 22 is preferably opened in the portion of the gland 2 close to the bottom shell 6, and the second locking hole is also arranged in the portion of the bottom shell 6 close to the gland 2, so that the locking column 11 can pass through both at the same time. The locking column 11 can be inserted from one side of the first locking hole 22, and can also be inserted from one side of the first locking hole 22, such as Figure 1 In the embodiment shown, the locking column 11 is inserted from one side of the first locking hole 22. The number of locking columns 11 can be one to achieve its locking function, but multiple locking columns 11 can also be provided to improve the uniformity of force. The locking column 11 passes through the first locking hole 22 on the gland 2 and the second locking hole on the bottom shell 6, thereby preventing the gland 2 and the bottom shell 6 from rotating relative to each other. Especially for water environments such as swimming pools, the locking of the locking member 1 can effectively prevent the gland 2 from loosening due to reasons such as footsteps and water flow impact.

[0052] See also Figure 1 In one embodiment of the present application, the locking member 1 also includes a connecting member 13 and a hook 12, the hook 12 and the locking column 11 are both connected to the connecting member 13, and the pressure cover 2 is provided with a slot; when the locking column 11 is inserted into the first locking hole 22 and the second locking hole, the hook 12 is engaged in the slot to prevent the locking column 11 from moving axially along the first locking hole 22.

[0053] In this embodiment, the function of the connecting member 13 is to connect the hook 12 and the locking column 11. The connecting member 13 can be in various forms, such as a block-shaped, sheet-shaped structure, etc. Its shape is mainly set according to the shape of the insertion position of the locking column 11. For example, the locking column 11 is inserted from one side of the gland 2, and the gland 2 is annular, then the corresponding connecting member 13 can also be set to be annular. The hook 12 cooperates with the slot, and the structures of the two are adapted to each other, so that the hook 12 can be mutually engaged with the slot. When the locking column 11 is inserted into the first locking hole 22 and the second locking hole, the hook 12 can be engaged in the slot to fix the hook 12, and the hook 12 and the locking column 11 are both connected to the connecting member 13. When the hook 12 is fixed, the locking column 11 is also fixed accordingly, so that it cannot move axially along the first locking hole 22 and the second locking hole, thereby preventing the locking column 11 from exiting the first locking hole 22 and the second locking hole.

[0054] See also Figure 1 In one embodiment of the present application, the first waterproof component 4 is provided with a first through hole 41, and the locking column 11 is inserted into the first through hole 41; a positioning column 62 is provided on the side of the bottom shell 6 facing the first waterproof component 4, and the first waterproof component 4 is provided with a second through hole 42, and the positioning column 62 is inserted into the second through hole 42 to position the first waterproof component 4.

[0055] The locking column 11 may or may not pass through the first waterproof member 4. In this embodiment, the first waterproof member 4 is provided with a first through hole 41. When the locking column 11 is inserted into the first locking hole 22 and the second locking hole, the locking column 11 is inserted into the first through hole 41, that is, the locking column 11 passes through the first waterproof member 4. By having the locking column 11 pass through the first waterproof member 4, on the one hand, it is beneficial to simultaneously arrange the first waterproof member 4 and the locking column 11 at the limited position where the gland 2 and the bottom shell 6 are connected to each other, and on the other hand, the locking column 11 can also play a certain positioning role for the first waterproof member 4.

[0056] However, when the locking column 11 passes through the first waterproof part 4, it is necessary to ensure that the position of the first through hole 41 of the first waterproof part 4 can just correspond to the first locking hole 22 and the second locking hole. In this embodiment, the pressure cover 2 and the bottom shell 6 are relatively rotated to press the first waterproof part 4. During the relative rotation of the pressure cover 2 and the bottom shell 6, it is easy to cause the first waterproof part 4 to follow the rotation, thereby causing the first waterproof part 4 to shift, and then causing the first through hole 41 to not be directly opposite the first locking hole 22 and the second locking hole, affecting the insertion of the locking column 11. In view of this situation, in this embodiment, a positioning column 62 is provided on the side of the bottom shell 6 facing the first waterproof part 4, and the first waterproof part 4 is provided with a second through hole 42. The positioning column 62 is inserted into the second through hole 42 to position the first waterproof part 4, thereby preventing the first waterproof part 4 from shifting, ensuring that the locking column 11 can be smoothly inserted and locked, and preventing the problem of reduced waterproof performance due to the displacement of the first waterproof part 4.

[0057] Underwater lamp 10 can be generally installed in a pipe connected to a water body by gluing or wrapping with tape. The gluing method can only be used once, which is not convenient for maintenance and replacement of underwater lamp 10 and is easy to damage the pipe. The tightness of the installation by wrapping with tape is not easy to control. If it is too loose, it is easy to fall off. If it is too tight, it is not easy to replace and is easy to damage the installed pipe.

[0058] See also Figure 2 In one embodiment of the present application, the underwater lamp 10 also includes a first mounting assembly, the first mounting assembly includes a first nut 81, a first connecting portion 63 is provided on the side of the bottom shell 6 facing away from the pressure cover 2, a first thread is provided on the first connecting portion 63, the first nut 81 is threadedly connected to the first thread, and a clamping space for clamping the mounting portion 9 is formed between the first nut 81 and the bottom shell 6.

[0059] The first installation assembly of this embodiment is mainly used for installing the underwater lamp 10 on a thinner side wall, such as the installation of the underwater lamp 10 on the thin side wall of a film swimming pool or a small landscape pool. Among them, the size of the first nut 81 is determined according to the size of the first connecting portion 63, and a relatively large size is usually used as much as possible to ensure the stability of the installation. The first connecting portion 63 is connected to the side of the bottom shell 6 away from the gland 2, so that the side of the gland 2 with a more luminous effect faces the water body. The first nut 81 is threadedly connected to the first thread, and a clamping space for clamping the mounting portion 9 is formed between the first nut 81 and the bottom shell 6. The mounting portion 9 is clamped by the clamping space to achieve the installation and fixation of the underwater lamp 10.

[0060] See also Figures 3 to 6During the specific installation, a mounting hole 91 is opened on the mounting portion 9 where the lamp is to be installed. The size of the mounting hole 91 is adapted to the first connecting portion 63 and the first nut 81, so that the first connecting portion 63 can pass through the mounting hole 91, while the first nut 81 and the bottom shell 6 cannot pass through the mounting hole 91. After the mounting hole 91 is opened, the first connecting portion 63 of the underwater lamp 10 passes through the mounting hole 91 from the inside to the outside and is exposed outside the mounting portion 9, and then the first nut 81 is threadedly connected with the first thread of the first connecting portion 63 outside the mounting portion 9, and the first nut 81 is continuously tightened until the first nut 81 and the bottom shell 6 tighten the mounting portion 9, so that the underwater lamp 10 is installed and fixed, and the circuit of the underwater lamp 10 can be directly arranged outside the mounting portion 9. When disassembling the underwater lamp 10, it is only necessary to reversely unscrew the first nut 81 to take out the underwater lamp 10 for replacement or repair.

[0061] See also Figure 2 In one embodiment of the present application, a second waterproof member 82 is sleeved on the first connecting portion 63 , and the second waterproof member 82 is in contact with the side of the bottom shell 6 facing away from the pressure cover 2 , and the clamping space is located between the first nut 81 and the second waterproof member 82 .

[0062] Because the second waterproof member 82 is to be sleeved on the first connection portion 63, the second waterproof member 82 is usually annular, or can be a strip structure wound on the first connection portion 63, and the second waterproof member 82 can be made of rubber, silicone, etc. The second waterproof member 82 is in contact with the side of the bottom shell 6 away from the gland 2, and the first nut 81 and the second waterproof member 82 clamp the mounting portion 9, and the second waterproof member 82 can be used to achieve a waterproof effect, preventing water inside the mounting portion 9 from seeping out from the mounting hole 91 on the mounting portion 9 to the outside.

[0063] See also Figure 7 In one embodiment of the present application, the underwater lamp 10 also includes a second mounting component, the first mounting component includes an elastic card 7, a second connecting portion 64 is provided on the side of the bottom shell 6 facing away from the pressure cover 2, the elastic card 7 is connected to the second connecting portion 64, and the elastic card 7 is used to be inserted into the mounting hole 91 of the mounting portion 9.

[0064] The first installation assembly of this embodiment is mainly used for the method of connecting a pipe on the wall of the pool and installing the underwater lamp 10 through the pipe. This installation method is usually used for the installation of the underwater lamp 10 in a thicker water body such as cement, soil, etc., where the installation part 9 is a second connection part 64. The second connection part 64 is arranged on the side of the bottom shell 6 away from the gland 2, so that the side of the gland 2 with a more luminous effect faces the water body. The elastic card 7 is an elastic clip. The specific structure of the elastic card 7 can be V-shaped, three-claw-shaped, spiral-shaped, etc., and can usually be made of metal or plastic. It can be inserted into the installation hole 91 of the installation part 9, so that the second connection part 64 is connected to the installation part 9, thereby realizing the installation of the underwater lamp 10.

[0065] See also Figures 8 to 12 During the specific installation, a mounting hole 91 can be opened on the mounting part 9 where the lamp is to be installed. The mounting hole 91 can usually be a pipe buried in the mounting part 9 so that the pipe is connected to the water body and the inner hole of the pipe is used as the mounting hole 91. Alternatively, a hole can be directly punched on the mounting part 9 as the mounting hole 91. The size of the mounting hole 91 is adapted to the second connecting part 64 and the elastic card 7 so that the second connecting part 64 can be inserted into the mounting hole 91 and the elastic card 7 can be stably engaged with the mounting hole 91. After the mounting hole 91 is opened, the second connecting part 64 of the underwater lamp 10 with the elastic card 7 installed is directly inserted into the mounting hole 91, and is pressed hard to make the elastic card 7 engage in the mounting hole 91, and the bottom shell 6 of the underwater lamp 10 is flush with and close to the mounting part 9, so that the underwater lamp 10 can be installed and fixed, and the circuit of the underwater lamp 10 can be arranged through the mounting hole 91. When disassembling the underwater lamp 10, it is only necessary to pull it outwards to separate the second connection portion 64 and the elastic clip 7 from the mounting hole 91. This will not cause damage to the mounting hole 91 and the lamp can be reused multiple times.

[0066] The elastic card 7 can be connected to the second connection portion 64 by welding, integral molding, clamping, thread connection and other methods. Figure 1 and Figure 7 In one embodiment of the present application, the underwater lamp 10 also includes a second nut 66, the second connecting portion 64 is provided with a second thread, the second connecting portion 64 is provided with an abutment portion at one end facing the bottom shell 6, the elastic card 7 is connected with a connecting ring 71, the connecting ring 71 is sleeved on the second connecting portion 64, the second nut 66 is threadedly connected to the second thread and the connecting ring 71 is clamped and fixed between the second nut 66 and the abutment portion.

[0067] In this embodiment, the second nut 66 mainly plays the role of fixing the elastic card 7, which is installed on the second thread of the second connecting part 64. The end of the second connecting part 64 facing the bottom shell 6 is provided with an abutment portion, which can be a protrusion structure independently provided on the second connecting part 64, or the bottom shell 6 can be used as the abutment portion. If the first connecting part 63 and the second connecting part 64 are provided at the same time, the first connecting part 63 can also be used as the abutment portion. The elastic card 7 is provided with a connecting ring 71, which can be sleeved on the second connecting part 64, and the second nut 66 is threadedly connected to the second thread. By tightening the second nut 66, the connecting ring 71 can be clamped and fixed between the second nut 66 and the abutment portion.

[0068] In addition to fixing the elastic card 7, the second nut 66 can also be used as a waterproof structure for connecting the circuit of the underwater lamp 10. The circuit passes through the second nut 66, and when the second nut 66 is tightened, it can play a certain waterproof role. Figure 1 In the illustrated embodiment, the second nut 66 is a waterproof nut, and a waterproof rubber plug 65 is arranged inside the second nut 66. By tightening the second nut 66, waterproofing of the line connection can be achieved.

[0069] In one embodiment of the present application, the underwater lamp 10 includes a first mounting component and a second mounting component, the first mounting component includes a first nut 81, a first connecting portion 63 is connected to the side of the bottom shell 6 facing away from the pressure cover 2, the second connecting portion 64 is connected to the end of the first connecting portion 63 away from the bottom shell 6, a first thread is provided on the first connecting portion 63, the first nut 81 is threadedly connected to the first thread, and a clamping space for clamping the mounting portion 9 is formed between the first nut 81 and the bottom shell 6.

[0070] In this embodiment, the bottom shell 6 is sequentially connected with the first connection part 63 and the second connection part 64. This is because the first connection part 63 is inserted into the mounting hole 91 of the mounting part 9, and the sizes are preferably not much different, so as to achieve higher stability. The second connection part 64 needs to be connected to the elastic card 7, and it is necessary to provide a relatively sufficient elastic compression and extension space for the elastic card 7. Therefore, the second connection part 64 has a smaller size relative to the mounting hole 91. That is to say, under normal circumstances, the size of the second connection part 64 is smaller than that of the first connection part 63. At the same time, the first mounting assembly requires the first nut 81 to clamp the mounting part 9 with the bottom shell 6. Therefore, the first connection part 63 is connected to the bottom shell 6, and the second connection part 64 is connected to the first connection part 63, so that both can play their respective functions, and the overall stability of the structure is also better. The bottom shell 6, the first connection part 63, and the second connection part 64 can be an integrally formed structure. Compared with the independent structure, the integrally formed structure can further improve its waterproof performance.

[0071] In this embodiment, the underwater lamp 10 includes both the first mounting assembly and the second mounting assembly, and can take into account two installation methods, and users can freely choose according to different usage scenarios. The two installation methods have been described in detail above, and will not be repeated here.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
