Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] like Figures 1 to 19 As shown, this embedded drainage channel linear in-ground light of the present invention includes a drainage channel 1, a linear light fixture 2, a drainage cover 3, and a support assembly 4. The drainage channel 1 is placed in an excavated ditch, the linear light fixture 2 and the drainage cover 3 are mounted on the drainage channel 1, and the support assembly 4 is mounted in a fixing opening 5 provided on the drainage channel 1, supporting the linear light fixture 2 and the drainage cover 3. The linear light fixture 2 or the drainage cover 3 can be laid according to actual needs.
[0021] The drainage trough 1 forms a drainage area 6 in the middle. The drainage area 6 is open at the top and is connected at both ends. The drainage trough 1 has multiple symmetrically arranged fixing ports 5, and fixing rods 7 are installed in the fixing ports 5. An electric wire placement groove 59 is provided on one inner wall of the drainage area 6, which can support the electric wires connecting the linear lamps 2.
[0022] The fixing rod 7 is composed of a first rod body 8, a second rod body 9 and a third rod body 10. The second rod body 9 connects the first rod body 8 and the third rod body 10. The diameter of the second rod body 9 is smaller than the diameter of the first rod body 8 and the third rod body 10. An annular region 11 is formed between the first rod body 8 and the third rod body 10.
[0023] The annular region 11, in conjunction with the laterally positioned limiting body 12, allows the limiting body 12 to be placed within the annular region 11. Since the diameters of the first rod 8 and the third rod 10 are larger than the diameter of the second rod 9, the first rod 8 restricts the position of the limiting body 12, ensuring that the limiting body 12 remains within the annular region 11 when the pushing body 13 is not pushed. When the pushing body 13 is pushed, the annular recess 14 reaches the position of the fixing rod 7, preventing the recessed annular recess 14 from obstructing the first rod 8. When the retaining block 22 is removed from the fixing opening 5, the limiting body 12 is no longer blocked by the first rod 8. Tool-free assembly and disassembly are possible.
[0024] The linear light fixture 2 is installed at the upper end of the drainage area 6, and multiple positioning rods 15 are provided at the lower end of the linear light fixture 2.
[0025] A drainage cover 3 is located at the upper end of the drainage area 6, and the drainage cover 3 has multiple strip grooves 16. A symmetrically arranged insertion plate 17 is located at the lower end of the drainage cover 3, and multiple pushing blocks 18 are located on the outer side of the insertion plate 17. The pushing blocks 18 are used to push the support member 19. The pushing blocks 18 are used to push the second support arm 20, causing the entire support member 19 to rotate around the first hinge rod 21.
[0026] The support assembly 4 is installed inside the fixing port 5. The support assembly 4 is used to support the linear lamp 2 and the drainage cover 3. The support assembly 4 is restricted within the fixing port 5 by the fixing rod 7. The support assembly 4 includes a retaining block 22, a support member 19, a rotating member 23, and a movable member 24. The support member 19, the rotating member 23, and the movable member 24 are all located in the middle of the retaining block 22.
[0027] The retaining blocks 22 are symmetrically arranged and have two locations, which are respectively limited by the fixing rod 7 and the pressing member 25. At the same time, the retaining blocks 22 can be connected to each other by the first hinge rod 21, while the rotating rod 26 is inserted in the middle of the retaining blocks 22.
[0028] The retaining block 22 is also provided with an opening 58, which is used for inserting a hand during installation and removal.
[0029] The middle of the retaining block 22 forms a retaining area 27. The middle of the retaining block 22 is provided with a pressing member 25 that cooperates with the fixing rod 7. A first spring 28 is sleeved on the pressing member 25. The position of the retaining block 22 is restricted by the cooperation between the pressing member 25 and the fixing rod 7.
[0030] The pressing component 25 includes a limiting body 12 and a pushing body 13. The limiting body 12 is composed of a plug 29, a fourth rod 30 and a threaded rod 31. The diameter of the plug 29 is larger than the diameter of the fourth rod 30, and the diameter of the fourth rod 30 is larger than the diameter of the threaded rod 31. An annular notch 14 is formed in the middle of the fourth rod 30. The first spring 28 is sleeved on one end near the threaded rod 31.
[0031] The pusher 13 consists of a sleeve 32 and a pusher disc 33. The diameter of the pusher disc 33 is larger than the diameter of the sleeve 32. The sleeve 32 has a threaded hole 34 in the middle that mates with the threaded rod 31.
[0032] The retaining block 22 has a fixing hole 35 that mates with the fixing rod 7 and a through hole 36 that mates with the pressing member 25 in the middle. The through hole 36 and the fixing hole 35 are connected. The through hole 36 is composed of a first through hole 37, a second through hole 38 and a third through hole 39. The inner diameters of the first through hole 37 and the third through hole 39 are equal. The inner diameter of the second through hole 38 is smaller than the inner diameter of the first through hole 37. The first spring 28 is located in the third through hole 39.
[0033] When the pusher 13 is pushed, the first spring 28 can be compressed. The first spring 28 is blocked by the connection between the second through hole 38 and the third through hole 39, so that it is compressed, ensuring that the pusher 13 can drive the limiter 12 to move, so that the annular notch 14 on the limiter 12 reaches the annular area 11 to achieve correspondence, thereby allowing the retaining block 22 to be installed or removed.
[0034] The holding area 27 is provided with a first rotation area 40, a second rotation area 41 and a third rotation area 42. The support member 19 is located in the first rotation area 40, the movable member 24 is located in the second rotation area 41 and the rotating member 23 is located in the third rotation area 42.
[0035] The support member 19 is disposed within the holding area 27 and is hinged within the holding area 27 via the first hinge rod 21. The support member 19 consists of a first support arm 43, a second support arm 20, and symmetrically arranged hinge portions 44. The second support arm 20 is provided with a positioning hole 45 that mates with the positioning rod 15. The linear lamp 2 is positioned and inserted for installation through the engagement of the positioning rod 15 and the positioning hole 45, and the linear lamp 2 is held in place by friction. A hinge area 46 is formed between the hinge portions 44. A first support surface 47 that mates with the first support arm 43 is provided in the first rotation area 40, and a second support surface 48 that mates with the hinge portion 44 is provided in the second rotation area 41. The first support surface 47 is used to limit the position of the first support arm 43, while the second support surface 48 is used to limit the position of the hinge portion 44.
[0036] The rotating component 23 is hinged to the middle of the retaining block 22, and a sliding hole 49 is provided in the middle of the rotating component 23. The rotating component 23 consists of a rotating rod 26 and a rotating body 50. The sliding hole 49 is provided on the rotating body 50, and the rotating rod 26 is provided at both ends of the rotating body 50. The retaining block 22 is provided with a rotating hole 51 that mates with the rotating rod 26, and a first hinge hole 52 that mates with the first hinge rod 21. The hinge part 44 is provided with a second hinge hole 54 that mates with the second hinge rod 53.
[0037] The movable part 24 is hinged to the support part 19. One end of the movable part 24 is inserted into the sliding hole 49, and the other end is hinged to the support part 19 through the second hinge rod 53. The movable part 24 is provided with a second spring 55, and one end of the second spring 55 is kept in contact with the rotating part 23.
[0038] The movable part 24 consists of a hinge end 56 and a sliding rod 57. The sliding rod 57 is disposed in the sliding hole 49, and the hinge end 56 is hinged in the hinge area 46 through the second hinge rod 53.
[0039] The support member 19 can rotate in the middle of the holding block 22 via the first hinge rod 21, while the movable member 24 can rotate around the second hinge rod 53. The movable member 24 can also be kept in a sliding position within the sliding hole 49 of the rotating member 23, and the rotating member 23 can rotate in the middle of the holding block 22 via the rotating rod 26.
[0040] like Figure 16 As shown, at this time, the rotating member 23 keeps the second support arm 20 extended out of the holding area 27, and supports the linear lamp 2 through the second support arm 20, while the first support arm 43 is placed on the first support surface 47. At this time, the second spring 55 is kept in a slightly compressed state, so that the rotating member 23 is pushed by the second spring 55, so that the first support arm 43 is placed on the first support surface 47.
[0041] like Figure 19 As shown, at this time, the rotating part 23 is pushed by the downward moving push block 18 on the drain cover plate 3, which pushes the second support arm 20 downward, thereby causing the entire support part 19 to rotate around the first hinge rod 21. During the rotation of the support part 19, it will drive the movable part 24 to rotate as well, causing one end of the movable part 24 to rotate around the second hinge rod 53 and the other end to rotate around the rotating rod 26, and causing the sliding rod 57 to slide in the sliding hole 49.
[0042] Among them, such as Figure 19 As shown, before rotation, the straight line between the first hinge rod 21 and the rotating rod 26 in the support member 19 is C1, and the straight line between the second hinge rod 53 and the rotating rod 26 in the support member 19 before rotation is C2. After rotation, the straight line between the second hinge rod 53 and the rotating rod 26 in the support member 19 is C3. The length of C1 is H1, the length of C2 is H2, and the length of C3 is H3. H1 > H2 > H3. Since the position of the rotating rod 26 remains unchanged, only rotating, the length of H2 is greater than H3. The length of the second spring 55 before rotation is greater than the length after rotation. Therefore, when the support member 19 rotates around the first hinge rod 21, the second spring 55 can push the second hinge rod 53 to place the hinge part 44 on the second support surface 48, so that the support member 19 cannot reset itself when it is not subjected to external force, thus maintaining the stability of the support member 19. The rotated support 19 causes the first support arm 43 to extend out of the holding area 27, and then the drain cover 3 is placed on the first support arm 43, so that the upper end face of the drain cover 3 is on the same horizontal plane as the upper end face of the holding block 22 and the drain groove 1.
[0043] This application is mainly used in outdoor locations where buried linear light fixtures 2 need to be installed. The advantage of this application is that it can be combined with a drainage system and the linear light fixtures 2 can be installed on the drainage system, avoiding the step of underground excavation. The installation is simple and can be flexibly combined according to actual needs. When used in different locations, the positions of the linear light fixtures 2 and the drainage cover 3 can be interchanged to achieve different combination effects.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
