Description

Technical Field

[0001] The present invention belongs to the field of architecture, and in particular to the field of light guide equipment. Background Art

[0002] Light pipes are a lighting system that collects natural light through a skylight and transmits it to indoor spaces through pipes for natural illumination. They are energy-saving, require no maintenance, and are energy-efficient. Natural light is soft, uniform, and full-spectrum, with no flicker, glare, or pollution. Furthermore, the UV-resistant coating on the skylight filter eliminates harmful radiation, offering significant advantages over artificial lighting. They are widely used in factories and underground buildings.

[0003] In practice, ground-level greenery can block light pipes, reducing the amount of light entering them. Rooftop light pipes, being farther from the ground, often offer better clearance. However, ground-level light pipes, especially in environments with extensive ground greenery, such as parks and suburban areas, are susceptible to obstruction by surrounding vegetation, particularly low-lying shrubs and free-growing trees. During early planning stages of light pipes, the size of the vegetation is often fixed, failing to account for the uncontrollable growth of vegetation in practice. Infrequent pruning of shrubs and trees can easily cause their branches and leaves to obstruct or even cover the light pipes. Frequent pruning inevitably increases maintenance and management costs. Furthermore, many areas (such as ground-level greenery in underground sewage treatment plants, factory rooftops, suburban underground facilities, and public land) often go unattended for years after construction.

[0004] The above problems can be avoided to a certain extent by raising and lengthening the light pipe. However, on the one hand, it is easy to increase the loss of light inside the light pipe and reduce the amount of light passing through. On the other hand, the higher light pipe appears very abrupt visually, destroying the overall aesthetic. At the same time, after the light pipe is raised, a lot of reinforcement is needed to avoid overturning and deformation caused by squeezing of green plants, so the cost is relatively high. Summary of the Invention

[0005] The present invention aims to provide a light guide tube to solve the technical problem of ground greening blocking the light shield at the top of the light guide tube.

[0006] In order to solve the above technical problems, the specific technical solutions adopted by the present invention are as follows:

[0007] A light guide tube includes a skylight and a light guide base, wherein the light guide base is arranged on the ground, and the skylight is arranged on the light guide base. The invention is characterized in that a fixing seat is provided around the light guide base, and the fixing seat is provided on the skylight and connected to the light guide base; a plurality of connecting rods are connected to the fixing seat, and a plurality of baffles are connected to the connecting rods.

[0008] Furthermore, the light pipe base is connected to a transverse extension pipe via a flange, and an end of the transverse extension pipe is connected to the light cover.

The outward expansion portion is connected to an expansion plate, and the expansion plate is provided with a plurality of threaded connection holes.

[0012] Furthermore, the baffle includes a first baffle and a second baffle, the first baffle and the second baffle are movably connected, both the first baffle and the second baffle are provided with connecting holes, and at least one connecting hole on the first baffle and the second baffle overlaps.

[0013] Furthermore, the universal screw is movably connected to a rotating base, the rotating base is provided with a fixing collar, and the fixing collar is movably connected to a locking port.

[0014] Furthermore, the fixing seat is provided with a first connecting hole and a second connecting hole, the second connecting hole is provided through-hole on the side of the fixing seat, and a sealing ring is provided on the fixing seat.

[0042] In order to better understand the purpose, structure and function of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figure 1 As shown, a light guide tube includes a light hood 1 and a light guide base 3. The light guide base 3 is set on the ground 2, the light hood 1 is set on the light guide base 3, and a fixing seat 4 is provided around the light guide base 3. The fixing seat 4 is set on the light hood 1 and connected to the light guide base 3.

[0045] like Figure 16 As shown, the fixing base 4 has a first connection hole 41 and a second connection hole 42. The second connection hole 42 is set through the side of the fixing base 4, and the fixing base 4 is provided with a sealing ring 44. The light pipe base 3 is specifically connected to the fixing base 4 by inserting an expansion screw into the concrete of the light pipe base 3 through the second connection hole 42.

[0046] As a preferred method, a connection hole may be reserved on the light pipe base 3 and then a screw may be passed through the second connection hole 42 for connection.

[0047] As a preferred method, a steel bar can be pre-reserved on the light guide base 3, with the end of the steel bar threaded. After the steel bar passes through the second connection hole 42, it is locked with a nut. For ease of installation, the pre-reserved steel bar on the light guide base 3 should be movably mounted on the light guide base 3 to facilitate installation of the fixing base 4.

[0048] like Figures 4 to 11 As shown, a plurality of connecting rods 7 are connected to the fixing seat 4 through a first connecting hole 41 via a universal screw 9 , and a plurality of baffles 8 are connected to the connecting rods 7 .

[0049] Specifically, universal screw 9 is connected to a rotating base 91, which is rotatably connected to universal screw 9 via a disc mounted on universal screw 9. The specific structure is conventional in the prior art and will not be described in detail here. A fixed collar 92 is provided on rotating base 91. One side of fixed collar 92 is open, and a locking opening 93 is movably connected to fixed collar 92 via a coil spring. The coil spring allows locking opening 93 to maintain contact with fixed collar 92, forming a closed loop with the fixed collar 92.

[0050] like Figure 11 As shown, fixed collars 92 are provided on both sides of the rotating base 91 to form two independent connecting rings. At the same time, there is a gap between the fixed collars 92, which can be used to engage with the connecting rod 7 or the baffle 8 to limit the position.

[0051] Specifically, the connecting rod 7 includes a pair of connecting plates 71, which are arranged in parallel. A plurality of auxiliary connecting rods 73 are connected between the connecting plates 71 to increase strength. At the same time, compared with a simple long connecting rod, the structure can reduce weight while ensuring strength. A plurality of threaded connection holes 72 are provided on the connecting plates 71.

[0052] Specifically, the baffle 8 includes a first baffle 81 and a second baffle 82. The first baffle 81 and the second baffle 82 are movably connected at their midpoints by a connecting buckle, allowing the first baffle 81 and the second baffle 82 to rotate relative to each other. The first baffle 81 and the second baffle 82 are each provided with connecting holes 83. The connecting holes 83 are distributed along the edges of the first baffle 81 and the second baffle 82, and at least one connecting hole 83 on the first baffle 81 and the second baffle 82 overlaps.

[0053] like Figure 14 As shown, during use, press the lock 93 to expose the opening of the fixing collar 92, pass the fixing collar 92 through the connecting hole 83, loosen the lock 93 to close the fixing collar 92, and then connect the universal screw 9 to the connecting rod 7 to complete the connection between the baffle 8 and the fixing base 4.

[0054] Specifically, during use, the fixing collar 92 can be passed through the auxiliary connecting rod 73 between the connecting plates 71 , and then the lock 93 can be released to close the fixing collar 92 , thereby completing the connection between the universal screw 9 and the connecting rod 7 .

[0055] The connection between the fixing seat 4 and the connecting rod 7 , and the connection between the connecting rod 7 and the baffle 8 are all connected through universal screws 9 .

[0056] like Figure 12 As shown, specifically, the connection between the connecting rod 7 and the fixing base 4 can be achieved by passing the universal screw 9 through the threaded connection hole 72 and connecting with the first connection hole 41 on the fixing base 4.

[0057] The connection between the connecting rod 7 and the fixing seat 4 can also be achieved by fastening the fixing collar 92 on the universal screw 9 with the auxiliary connecting rod 73 between the connecting plate 71 , and the universal screw 9 is then connected to the first connecting hole 41 on the fixing seat 4 .

[0058] like Figure 15 As shown, the baffle 8 can also be connected to a single connecting rod 7. Two opposite connecting holes 83 are selected on the baffle 8, and the fixing rings 92 are respectively passed through the connecting holes 83. Then, the adjacent auxiliary connecting rod 73 is inserted, and then the lock 93 is released to close the fixing ring 92 to complete the connection.

[0059] Example 2

[0060] like Figure 2 As shown, in this embodiment, the light guide base 3 is connected to a transverse extension conduit 5 via a flange 6, the end of which is connected to the skylight hood 1. The transverse extension conduit 5 has a Z-shaped side, which enables the skylight hood 1 to translate laterally to avoid obstructions above its original position. While enabling the skylight hood 1 to translate laterally, the flange 6 can also rotate around the original infrastructure, adapting to a variety of practical installation environments.

[0061] Example 3

[0062] like Figure 4 、 Figure 12 and Figure 13 As shown, one section of the connecting plate 71 is provided with an outward expansion portion 76, which increases the gap between the connecting plates 71 after they are assembled into the connecting rod 7. The other end is provided with a slot 74 for connecting with the auxiliary connecting rod 73. The outward expansion portion 76 is connected to an expansion plate 77, which is provided with a plurality of threaded connection holes 72.

[0063] During use, if Figure 6 As shown, the connecting rod 7 is inserted into the outer expansion portion 76 of the other connecting rod, the connecting slot 74 is engaged with the auxiliary connecting rod 73, and the universal screw 9 is screwed in from the side to fix the two connecting rods 7 and achieve the purpose of extending the connecting rod 7.

[0064] In actual use, since a plurality of threaded connection holes 72 are provided on the expansion plate 77 , by fixing the expansion plate 77 on different threaded connection holes 72 through the universal screws 9 , the function of controlling the angle of the two connecting rods 7 after being combined and connected can be achieved.

[0065] In actual use, in addition to being connected to the auxiliary connecting rod 73 in the area of ​​the outward expansion portion 76, the connecting slot 74 can also be engaged with the auxiliary connecting rod 73 in the middle of the other connecting rod 7 when the two connecting rods 7 meet vertically, thereby achieving horizontal limitation.

[0066] In actual use, the outward expansion portion 76 can also be connected to the middle portion of the connecting rod 7 and fixed by a universal screw 9 passing through the threaded connection hole 72 and the connection hole 83.

[0067] Example 4

[0068] like Figure 16 As shown, in this embodiment, a staggered platform 46 is provided on the fixing seat 4, a sealing ring 44 is arranged on the staggered platform 46, a locking ring 43 is provided on the sealing ring 44, and the locking ring 43 is connected to the staggered platform 46 by screws. A drainage hole 45 is provided at the bottom of the staggered platform 46, which is connected to the outside of the fixing seat 4.

[0069] After the fixing base 4 is installed, the locking ring 43 is tightened by screws, and the locking ring 43 squeezes the sealing ring 44, so that the sealing ring 44 is more tightly combined with the light cover 1 and the offset 46, thereby achieving the purpose of waterproofing. When there is rain, the rainwater blocked by the sealing ring 44 flows out through the drainage hole 45.

[0070] Example 5

[0071] like Figure 16 and 17 As shown, in this embodiment, the cross-section of the locking ring 43 is an inverted trapezoid, with one side of the locking ring 43 in close contact with the side wall of the offset 46 and one side in contact with the sealing ring 44. As the locking ring 43 moves downward under the drive of the screw during the locking process, the squeezing force on the sealing ring 44 increases, thereby achieving the purpose of locking.

[0072] The sealing ring 44 has a quadrilateral cross section, with a beveled side on the side in contact with the locking ring 43, and is provided with a plurality of layers of limiting grooves 441. The limiting grooves 441 can ensure that the relative positions of the locking ring 43 and the sealing ring 44 are fixed.

[0073] Example 6

[0074] like Figure 10 As shown, in this example, the fixing collar 92 is provided with a reverse hook 94, and the locking opening 93 is provided with a recess that cooperates with the reverse hook 94. During use, the connection between the fixing collar 92 and the locking opening 93 can be ensured to be more stable.

[0075] Use Case 1

[0076] In this use case, if Figure 3 As shown, a universal screw 9 is passed through a threaded connection hole 72 on the connecting rod 7 on the fixing base 4 and connected to the first connection hole 41 on the fixing base 4, so that the connecting rod 7 is horizontally connected to the fixing base 4. A pillow 51 is provided on the connecting rod 7 to support the transverse extension guide 5 without the help of an external structure, thereby maintaining the stability of the light guide's light inlet section.

[0077] Use Case 2

[0078] In this use case, if Figure 18 As shown, in this use case, the transverse extension catheter 5 is not extended horizontally as in Use Case 1, but rather extends diagonally upward. The fixing collar 92 on the universal screw 9 is inserted into the auxiliary connecting rod 73 of the connecting rod 7. The universal screw 9 is respectively connected to the second connecting hole 42 on the side of the fixing base 4 and the first connecting hole 41 on the top. The outer expansion portion 76 of the connecting rod 7 in the second connecting hole 42 is connected to the middle portion of the connecting rod 7 connected to the first connecting hole 41. The two connecting rods form an oblique upward support to support the transverse extension catheter 5.

[0079] The fixing base 4 on the skylight 1 is connected to the connecting rod 7 through a universal screw 9 thread, and the connecting rod 7 is further connected to the connecting rod 7 until it reaches the ground. This further improves the stability of the structure under external force.

[0080] In this use case, the first connecting hole 41 and the second connecting hole 42 on the fixing base 4 can also be connected to multiple sets of connecting rods 7 to further improve the structural stability.

[0081] Use Case 3

[0082] In this use case, the connecting rods 7 are stacked together and connected by screws, and the lowest longitudinal connecting rod 7 is connected to the fixing seat 4, which can replace the pillow 51 in use case 1.

[0083] Use Case 4

[0084] In this use example, the baffles 8 may not be connected between the connecting rods 7, and may be replaced by flexible materials such as nets, curtains, and tarpaulins.

[0085] Use Case 5

[0086] like Figure 12 As shown, the baffle 8 is connected between the connecting rods 7, and the baffle 8 and the connecting rod 7 are on the same horizontal plane. The connecting rod 7 uses the connection structure in Example 2 to form a baffle composed of baffles 8 around the fixed seat 4, which blocks the vegetation on the side and maintains the light-clearing space above the skylight 1.

[0087] Use Case 6

[0088] like Figure 13 and Figure 14 As shown, in this use example, the baffle 8 is connected between the connecting rods 7 perpendicular to the axial direction of the connecting rod 7, the fixing ring 92 passes through the connecting hole 83, and then the adjacent auxiliary connecting rod 73 is inserted to connect the baffle 8 and the connecting rod 7, and finally the universal screw 9 is used to pass through the threaded connection hole 72 on the connecting rod 7 and fix it to the fixing seat 4.

[0089] In actual use, the baffles 8 are perpendicular to the ground, which can reduce the light blocking of the vegetation below. At the same time, the gaps between the baffles 8 can guide the growth direction of the vegetation and keep it between the baffles 8 without affecting the light clearance above the light cover 1 or the growth of the vegetation.

[0090] Use Case 7

[0091] like Figure 20 As shown, the fixing collar 92 passes through the connecting hole 83 on the baffle 8, and the universal screw 9 is connected to the threaded connecting hole 72. The connecting rod 7 is connected to the fixing base 4 through the universal screw 9.

[0092] It is worth emphasizing that, in this use example, the connecting rod 7 can be connected to the first connecting hole 41 or the second connecting hole 42 via a universal screw 9 .

[0093] When the connecting rod 7 is connected to the first connecting hole 41 through the universal screw 9, the baffle 8 is arranged horizontally.

[0094] When the connecting rod 7 is connected to the second connecting hole 42 through the universal screw 9, the baffle 8 is arranged vertically.

[0095] In the above usage examples, the number of connections of the connecting rod 7 and the number of baffles 8 connected to the connecting rod 7 can be adjusted according to actual usage requirements.

[0096] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
