Description

Technical Field

[0001] The utility model relates to the technical field of house exhaust, in particular to a novel roof exhaust pipe device which is adjustable, prevents pipe blocking and is easy to construct. Background Art

[0002] The inverted roof is still widely used in building roof construction due to its low cost. However, since the insulation layer of the inverted roof is located under the waterproof layer, the inverted roof completely seals the insulation layer, so an exhaust pipe needs to be installed during construction.

[0003] When arranging the exhaust pipe, it is necessary to drill holes in the insulation layer so that the insulation layer can be exhausted through the exhaust pipe. When arranging the exhaust pipe, the thickness and position of the leveling layer and the insulation layer are often not fixed. Therefore, the drilling position of the exhaust pipe is not easy to determine, and the exhaust pipe may also face the problem of insufficient length. Therefore, an exhaust pipe device is needed to solve the problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a novel roof exhaust pipe device which is adjustable, anti-blocking and easy to construct, and can adapt to leveling layers and insulation layers of different positions and thicknesses, so as to realize the adjustability, anti-blocking and easy construction of the exhaust pipe.

[0005] The technical solution to achieve the purpose of the utility model is: a new type of roof exhaust pipe device which is adjustable, anti-blocking and easy to construct, including an exhaust pipe, a waterproof cover is fixedly connected to the exhaust pipe, a plurality of cutting grooves are opened at the bottom end of the exhaust pipe, a ventilation component is arranged inside the exhaust pipe, the ventilation component includes a swivel, a first through hole and a second through hole, a plurality of swivels are rotatably connected to the interior of the exhaust pipe, a plurality of first through holes are opened on the exhaust pipe, a plurality of second through holes are opened on a plurality of swivels, and a rotating component is arranged inside the exhaust pipe.

[0006] Preferably, the ventilation assembly further includes a limiting ring, two of the limiting rings are fixedly connected to the inner wall of the exhaust pipe, and a plurality of rotating rings are located between the two limiting rings.

[0007] Preferably, the rotating assembly comprises a fixing rod and an elliptical hole, a plurality of the fixing rods are respectively fixedly connected to the inner walls of a plurality of rotating rings, and a plurality of the elliptical holes are respectively opened on the plurality of fixing rods.

[0008] Preferably, the rotating assembly further comprises a vertical rod and an elliptical block, the vertical rod passes through a plurality of elliptical holes, and the elliptical block is fixedly connected to the vertical rod.

[0009] Preferably, the rotating assembly further comprises a cross bar, wherein the cross bar is fixedly connected to the vertical bar, and the cross bar is perpendicular to the vertical bar.

[0010] Preferably, the rotating assembly further comprises a rubber pad and a groove, a plurality of the rubber pads are respectively fixedly connected to a plurality of rotating rings, and a plurality of the grooves are opened on the inner wall of the exhaust pipe.

[0011] Compared with the prior art, the utility model has the following significant advantages:

[0012] First: In the utility model, when installing the exhaust pipe, the waterproof cover on the top is used to prevent rainwater from entering the exhaust pipe when it rains. The exhaust pipe is relatively long and has a plurality of cutting grooves at the bottom. The bottom part can be easily cut along the cutting grooves to shorten the length of the entire exhaust pipe. Therefore, during installation, the exhaust pipe can be shortened by cutting at different cutting grooves according to the layer thickness. After the exhaust pipe is installed, the angle of the exhaust pipe can be adjusted by a spirit level at the top of the exhaust pipe.

[0013] Second: In the utility model, after the exhaust pipe is installed, the position of the insulation layer can be determined according to the building information. According to the position of the insulation layer, the horizontal rod is pulled to move the vertical rod in the multiple elliptical holes, so that the elliptical block is embedded in the elliptical hole on the fixed rod. When the elliptical block is embedded in an elliptical hole, the vertical rod can be rotated to drive the elliptical block to rotate, and then the fixed rod and the swivel can be rotated to make the second through hole on the swivel coincide with the corresponding first through hole on the exhaust pipe. At this time, at the position of the swivel, the inside and outside of the exhaust pipe can be ventilated. Therefore, it is only necessary to determine the position of the insulation layer, and then rotate the swivel at that position to make the first through hole and the second through hole at that position coincide, so that the insulation layer can be exhausted by the exhaust pipe.

[0014] In the utility model, the cutting groove makes the length of the exhaust pipe adjustable, and the insulation layer can be ventilated only when the first through hole and the second through hole overlap, so the other first through holes and the second through holes can avoid being blocked and prevent debris from falling into the exhaust pipe.

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a novel roof exhaust pipe device that is adjustable, prevents pipe blocking, and is easy to construct through improvement. The technical solution of the utility model is:

[0024] like Figure 1-Figure 4 As shown, a novel roof exhaust pipe device which is adjustable, anti-blocking and easy to construct comprises an exhaust pipe 1, to which a waterproof cover 2 is fixedly connected, a plurality of cutting grooves 3 are provided at the bottom end of the exhaust pipe 1, a ventilation component 4 is arranged inside the exhaust pipe 1, the ventilation component 4 comprises a swivel 41, a first through hole 42 and a second through hole 43, a plurality of swivels 41 are rotatably connected to the inside of the exhaust pipe 1, a plurality of first through holes 42 are provided on the exhaust pipe 1, a plurality of second through holes 43 are provided on a plurality of swivels 41, a rotating component 5 is arranged inside the exhaust pipe 1, a plurality of swivels 41 can block a plurality of first through holes 42, and when the swivel 41 rotates, the first through holes 42 and the second through holes 43 can be overlapped, and at this time the exhaust pipe 1 can be ventilated through the first through holes 42 and the second through holes 43, and therefore the swivel 41 of the corresponding height can be rotated according to the position of the thermal insulation layer so that the thermal insulation layer can be exhausted through the exhaust pipe 1.

[0025] Furthermore, the ventilation component 4 also includes a limiting ring 44, two limiting rings 44 are fixedly connected to the inner wall of the exhaust pipe 1, and multiple swivels 41 are located between the two limiting rings 44. The two limiting rings 44 can clamp the multiple swivels 41 in the middle to prevent the swivels 41 from falling off.

[0026] Furthermore, the rotating assembly 5 includes a fixing rod 51 and an elliptical hole 52. The fixing rods 51 are respectively fixedly connected to the inner walls of the rotating rings 41. The elliptical holes 52 are respectively opened on the fixing rods 51. The elliptical hole 52 is a hole with an elliptical opening in cross section.

[0027] Furthermore, the rotating assembly 5 also includes a vertical rod 53 and an elliptical block 54. The vertical rod 53 passes through a plurality of elliptical holes 52. The elliptical block 54 is fixedly connected to the vertical rod 53. The cross-section of the vertical rod 53 is circular. Therefore, when the vertical rod 53 rotates in the elliptical hole 52, it will not drive the fixed rod 51 to rotate. When the elliptical block 54 is embedded in the elliptical hole 52, the corresponding fixed rod 51 and the swivel 41 will rotate.

[0028] Furthermore, the rotating assembly 5 also includes a cross bar 55, which is fixedly connected to the vertical bar 53. The cross bar 55 is perpendicular to the vertical bar 53. The length of the cross bar 55 is greater than the diameter of the exhaust pipe 1, so the cross bar 55 can prevent the vertical bar 53 from falling into the exhaust pipe 1.

[0029] Furthermore, the rotating assembly 5 also includes a rubber pad 56 and a groove 57. The multiple rubber pads 56 are respectively fixedly connected to the multiple rotating rings 41. The multiple grooves 57 are opened on the inner wall of the exhaust pipe 1. The rubber pad 56 is elastic. Therefore, when the rubber pad 56 rotates with the rotating ring 41, when it is embedded in the groove 57, an obvious sense of pause can be felt, so it can be sensed whether the rotating ring 41 is rotated to the position where the first through hole 42 and the second through hole 43 overlap.

[0030] The specific working method is: when installing the exhaust pipe 1, the waterproof cover 2 on the top is used to prevent rainwater from entering the exhaust pipe 1 when it rains. The exhaust pipe 1 is relatively long and has a plurality of cutting grooves 3 at its bottom. The bottom portion can be easily cut along the cutting grooves 3 to shorten the length of the entire exhaust pipe 1. Therefore, during installation, the exhaust pipe 1 can be shortened by cutting at different cutting grooves 3 according to the layer thickness. After the exhaust pipe 1 is installed, the angle of the exhaust pipe 1 can be adjusted at the top of the exhaust pipe 1 through a level to make the exhaust pipe 1 as vertical as possible. Then, according to the building information, the position of the insulation layer is determined. According to the position of the insulation layer, the horizontal rod 55 is pulled to move the vertical rod 53 in the plurality of elliptical holes 52, thereby making the elliptical block 5 4 is embedded in the elliptical hole 52 on the fixing rod 51. When the elliptical block 54 is embedded in a certain elliptical hole 52, the vertical rod 53 can be rotated to drive the elliptical block 54 to rotate, thereby rotating the fixing rod 51 and the rotating ring 41. When the rotating ring 41 rotates, the rubber pad 56 on it can be embedded from one groove 57 to another groove 57. At this time, the second through hole 43 on the rotating ring 41 will coincide with the corresponding first through hole 42 on the exhaust pipe 1. At this time, the position of the rotating ring 41 is such that the inside and outside of the exhaust pipe 1 can be ventilated. Therefore, it is only necessary to determine the position of the thermal insulation layer, and then rotate the rotating ring 41 at this position to coincide with the first through hole 42 and the second through hole 43 at this position, so that the thermal insulation layer can be exhausted by the exhaust pipe 1.

Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
