[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 10 As shown, this embodiment discloses a reserved pipeline for ventilation and smoke exhaust pipe, including a plurality of pipe bodies 1, and the plurality of pipe bodies 1 are connected to form a pipeline. Figure 1 As shown, the tube body 1 is a thin-walled rectangular parallelepiped structure, and a tube body channel 11 is provided in the tube body 1. The tube body channel 11 runs through the tube body 1 in the length direction, and the tube body channels 11 are interconnected to form a ventilation and smoke exhaust pipeline.

[0034] like Figure 1 , Figure 3 As shown, the pipe body 1 is installed with a connecting component 4, and the two pipe bodies 1 are butted together through the connecting component 4 and fixed with bolts. Figure 1 , Figure 2 As shown, the pipe body 1 is fixed to the wall 3 through a bracket 31 , the wall 3 is located above the pipe body 1 , the pipe body 1 passes through the bracket 31 , and the bracket 31 supports the pipe body 1 .

[0035] like Figure 1 As shown, the tube body 1 includes a bottom plate 12 at the bottom, and the bottom plate 12 is provided with a bottom plate through hole 121. The bottom plate through hole 121 is formed along the length direction of the bottom plate 12 (i.e. Figure 1 Two bottom plate through holes 121 are provided (in the middle and left and right directions), and the bottom plate through holes 121 pass through the bottom plate 12 from top to bottom.

[0036] A sealing plate 6 is installed at the bottom of the bottom plate 12 , and the top surface of the sealing plate 6 is in contact with the bottom surface of the bottom plate 12 , so that the sealing plate 6 seals the bottom of the bottom plate through hole 121 .

[0037] Combination Figure 1 , Figure 3, a limit strip 2 is fixedly installed at the bottom of the bottom plate 12, and the limit strip 2 is located on both sides of the length direction of the bottom plate 12, and the limit strip 2 is bent into an L shape. The limit strip 2 is provided with a groove body 21, and the groove body 21 passes through the length direction of the tube body 1. The groove bodies 21 are inserted into the two sides of the sealing plate 6 respectively. The length direction of the sealing plate 6 is arranged along the length direction of the tube body 1, and the minimum distance between the two limit strips 2 is less than the width of the sealing plate 6. The upper and lower heights of the groove body 21 are greater than twice the thickness of the sealing plate 6, and the sealing plate 6 can be pulled out along the length direction of the groove body 21 after moving downward.

[0038] like Fig.10 As shown, there is a height difference between the bottoms of two adjacent slots 21, and the slot 21 with the lower bottom position (i.e. Fig.10 The height difference between the inner bottom surface of the middle right slot body 21 and the bottom surface of the other limiting strip 2 is greater than the thickness of the sealing plate 6. When removing the sealing plate 6, the sealing plate 6 can be moved from the slot body 21 at the higher bottom position to the slot body 21 at the lower bottom position, and then pulled out from the slot body 21 at the lower bottom position to complete the disassembly, so as to facilitate cleaning.

[0039] like Figure 1 As shown, the wall 3 is fixedly installed with a bracket 2 32, and the bracket 2 32 is fixedly installed with a cylinder 1 33, combined with Figure 5 The inner wall of the cylinder 1 33 is slidably connected with a slider 35, and the slider 35 can move up and down. The inner wall of the cylinder 1 33 is provided with a groove, and the outer wall of the slider 35 is provided with a corresponding protrusion, and the protrusion of the slider 35 is inserted into the groove of the cylinder 1 33 to limit the circumferential rotation of the slider 35.

[0040] The slider 35 is fixedly mounted with a fastener 7 , which is inserted into the slider 35 and is a nut. The bottom surface of the fastener 7 fits with the inner bottom surface of the slider 35 . The bottom surface of the slider 35 is provided with a through hole, and the outer diameter of the through hole is larger than the inner hole of the fastener 7 .

[0041] A pressure plate 36 is installed on the top of the slider 35, and the bottom surface of the pressure plate 36 abuts against the top surface of the fastener 7, and the bottom surface of the fastener 7 abuts against the inner bottom surface of the slider 35 to fix the fastener 7. The outer periphery of the fastener 7 is hexagonal, and the slider 35 is correspondingly provided with a hexagonal inner hole. Therefore, after the fastener 7 is inserted into the slider 35, the fastener 7 cannot rotate.

[0042] A cover plate 38 is installed on the top of the cylinder 1 33, and a spring 1 37 is placed in the cylinder 1 33. The spring 1 37 is located above the slider 35, and the upper end of the spring 1 37 abuts the cover plate 38, and the lower end of the spring 1 37 abuts the upper end of the pressure plate 36 to press the slider 35. A spring 2 39 is also placed in the cylinder 1 33, and the spring 2 39 is located below the slider 35. The upper end of the spring 2 39 abuts the bottom of the slider 35, and the lower end of the spring 2 39 abuts the bracket 2 32. The spring 1 37 and the spring 2 39 are both in a compressed state.

[0043] like Figure 1As shown, it also includes an insertion rod 5, which passes through the tube body 1 from the bottom of the tube body 1 and extends to the top of the tube body 1. Figure 1 , Figure 8 The sealing plate 6 is provided with a through hole 61, which is connected from top to bottom. The through hole 61 is located below the bottom plate 12, and the through hole 61 is staggered with the bottom plate through hole 121 to prevent the two from being connected. Figure 4 , Figure 8 , as shown, the cross-section of the through hole 61 is rectangular, and the insertion rod 5 includes a handle 51, which is a rectangular parallelepiped structure, and the handle 51 can pass through the through hole 61. Specifically, the length dimension of the handle 51 is smaller than the length dimension of the through hole 61, and the width dimension of the handle 51 is smaller than the width dimension of the through hole 61. The length of the handle 51 is greater than the width of the through hole 61, so that when the length direction of the handle 51 is set in the same direction as the width direction of the through hole 61, the handle 51 cannot pass through the through hole 61, so that when the handle 51 is located above the through hole 61, the top of the handle 51 can abut against the sealing plate 6 to support the sealing plate 6. As shown Fig. 9 As shown, when the handle 51 is rotated so that the length direction of the handle 51 is in the same direction as the length direction of the through hole 61, the handle 51 can pass through the through hole 61 to move the sealing plate 6 downwardly away from the insertion rod 5, and then the sealing plate 6 can be taken out.

[0044] like Figure 5 As shown, the insertion rod 5 also includes a rod head 52 at the top and a threaded portion 53 below the rod head 52, and the threaded portion 53 is arranged on the outer wall of the insertion rod 5. A guide hole 361 is arranged at the bottom of the pressure plate 36, and the rod head 52 is inserted into the guide hole 361. The threaded portion 53 is threadedly connected with the fastener 7. The guide hole 361 is arranged to facilitate the connection between the threaded portion 53 and the fastener 7. When the threaded portion 53 and the fastener 7 are just abutted up and down, the rod head 52 is inserted into the guide hole 361.

[0045] When the threaded portion 53 of the insertion rod 5 is screwed into the fastener 7 , since the spring 1 37 is in a compressed state, the spring 1 37 generates a downward pressure on the fastener 7 to facilitate the threaded portion 53 to be screwed into the fastener 7 .

[0046] like Figure 5 As shown, it also includes a second cylinder 34, which is located below the slider 35. A limit plate 341 is installed on the top of the second cylinder 34, and the insertion rod 5 passes through the second cylinder 34 and the limit plate 341. Figure 5 , Figure 6 As shown, the insertion rod 5 is installed with a fixing sleeve 54, which is a cylindrical structure. The fixing sleeve 54 is inserted into the insertion rod 5, and the fixing sleeve 54 is provided with extension bodies 541 on both sides. The limit plate 341 is provided with a through groove 3411, which passes through the limit plate 341 from top to bottom. The through groove 3411 is located on both sides of the limit plate 341, and the extension body 541 can pass through the through groove 3411. Figure 8As shown, when the upper end of the sealing plate 6 is in contact with the bottom plate 12 and the upper end of the handle 51 supports the sealing plate 6, the insertion rod 5 is in this position, and the top of the fixing sleeve 54 is at the same height as the bottom of the limiting plate 341; when the sealing plate 6 is taken out, the insertion rod 5 is moved up until the upper end of the handle 51 abuts against the bottom of the bottom plate 12, and the extension body 541 moves to a position where its bottom is higher than the limiting plate 341. By rotating the insertion rod 5, the extension body 541 can be staggered with the through groove 3411, so that the limiting plate 341 can hang on the insertion rod 5 and maintain the insertion rod 5 at a higher position, thereby facilitating the sealing plate 6 to slide the insertion rod 5 downward.

[0047] A method for assembling a reserved pipeline of a ventilation and smoke exhaust pipe comprises the following assembly steps:

[0048] ① After the pipe body 1 is hung on the bracket 31, it is connected through the connecting component 4 to form a connecting pipeline.

[0049] ② A sealing plate 6 is installed at the bottom of the bottom plate 12, and the sealing plate 6 is connected to the bottom plate 12 by screws.

[0050] ③ The insertion rod 5 passes through the through hole 61 and the tube body 1, and the upper end of the insertion rod 5 extends out of the upper end of the tube body 1. Figure 7 As shown, the rod head 52 is inserted into the guide hole 361, the top of the threaded portion 53 abuts against the bottom of the fastener 7, and the spring 1 37 is in a compressed state.

[0051] ④ Rotate the insertion rod 5. Under the downward pressure of the spring 37, the threaded portion 53 of the fastener 7 is screwed into the fastener 7. The rod handle 51 moves upward to be close to the bottom of the sealing plate 6, and the length direction of the rod handle 51 is set along the width direction of the through hole 61.

[0052] During disassembly, since there is a lot of dust and other debris on the upper end surface of the sealing plate 6, after the screws between the sealing plate 6 and the bottom plate 12 are removed, the sealing plate 6 will not fall immediately because the rod handle 51 can hold the sealing plate 6, thereby preventing injury to the operator, and dust and other debris on the sealing plate 6 will not fall off in large quantities. If the sealing plate 6 is still adhered to the bottom plate 12 after the screws are removed, the sealing plate 6 can be separated from the bottom plate 12 by knocking, and the sealing plate 6 will not accidentally fall during the knocking process, which is highly safe.

[0053] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
