Description

Technical Field

[0001] The utility model relates to a ventilation system, in particular to a building ventilation component. Background Art

[0002] Whether it is an industrial building or a civil building, a ventilation system can be installed inside the building to improve the air circulation inside the building. The ventilation system mainly consists of ventilation ducts and ventilation fans, and the ventilation ducts are composed of several ventilation components connected end to end. The material of the ventilation components can be metal or non-metallic, and generally needs to have fire resistance. The ventilation components need to be docked with each other, and the docking parts need to have good airtightness and be fixed to the building through positioners. At present, the two ends of the ventilation component are respectively provided with a first connecting member and a second connecting member, and the two connecting members are tightly docked by bolts. During actual installation, the two connecting members that need to be docked need to face each other so that the screw holes face each other. Due to the large size of the ventilation components, the alignment process is not easy. Then, nearly ten bolts need to be installed and tightened. Therefore, the installation efficiency is not high and the installation progress rate is slow. Summary of the Invention

[0003] The utility model provides a building ventilation component, which solves the problems in the prior art of low efficiency and great difficulty in the butt-jointing installation of ventilation components.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: a building ventilation component, comprising a ventilation pipe body, a first connecting piece arranged at one end of the ventilation pipe body and a second connecting piece arranged at the other end of the ventilation pipe body, characterized in that: the first connecting piece comprises a first pipe sleeve fixed to the end of the ventilation pipe body and a first docking frame integrally connected to the outer end of the first pipe sleeve, the first docking frame is a hollow frame structure composed of an upper frame piece, a lower frame piece, a left frame piece and a right frame piece, the bottom of the lower frame piece is provided with an upper folding piece folded upwards, the right frame piece is provided with a left folding piece folded leftwards, the left frame piece is provided with a left folding piece folded leftwards, and the left frame piece is provided with a left folding piece folded leftwards. The plate is provided with a left insert, and the number of left opening slots is consistent with the number of left folding tabs and the heights correspond one to one. The second connecting member includes a second pipe sleeve fixed to the end of the ventilation duct body and a second docking frame integrally connected to the outer end of the second pipe sleeve. The second docking frame is also composed of a hollow frame structure consisting of an upper frame piece, a lower frame piece, a left frame piece, and a right frame piece. The top of the upper frame piece is provided with a lower folding tab that folds downward, the left frame piece is provided with a right folding tab that folds rightward, and the right frame piece is provided with a right insert, the number of right inserts is consistent with the number of right folds, and the heights correspond one to one. The number and distribution height of the left and right folding tabs are consistent. It should be noted that the spacing between adjacent left or right folding tabs needs to be greater than the width of the left or right insert.

[0005] The installation method of the present invention is to first dock several ventilation duct bodies on the ground, and then hoist the sections to the corresponding installation positions of the building for fixed installation. When docking two ventilation duct bodies, it is necessary to align the first connector of one ventilation duct body with the second connector of the other ventilation duct body, and then lift the second connector so that the two connectors are staggered a certain distance up and down. At this time, the right folding piece on the second connector is entirely located above the left inserting piece on the first connector, and the right inserting piece on the second connector is entirely located above the left folding piece. Then, the ventilation duct body is moved so that the two adjacent first docking frames abut against the second docking frames. After releasing the folding piece, the second connector falls under gravity, so that the right folding piece and the right inserting piece simultaneously form an insertion with the left inserting piece and the left folding piece, and at the same time, the upper folding piece is inserted into the lower frame piece, and the lower folding piece is inserted into the upper frame piece, so that the first docking frame and the second docking frame are completely fixedly connected. The width of the slot gap formed in all the folding pieces is adapted to the thickness of the corresponding inserting piece, ensuring that after insertion, the first docking frame and the second docking frame are tightly connected, ensuring the airtightness of the docking. The narrower the width of the insert and the fold, the smaller the lifting height of the second connecting member, making the present invention easier to operate in a narrow space, but correspondingly, the number of the insert and the fold needs to be increased to ensure the connection strength.

[0006] Furthermore, the ventilation pipe body is a square tube structure or a round tube structure.

[0007] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention is fixed by plugging the insert and the folding piece into each other, and the plugging method is simple, with the effect of efficient disassembly and assembly, which can significantly improve the installation efficiency.

[0015] Example 1: See Figure 1 and Figure 2 A building ventilation component includes a square tubular ventilation pipe body 10, a first connecting piece 100 provided at one end of the ventilation pipe body, and a second connecting piece 200 provided at the other end of the ventilation pipe body. The first connecting piece includes a first pipe sleeve 110 fixed to the end of the ventilation pipe body and a first docking frame 120 integrally connected to the outer end of the first pipe sleeve. The first docking frame is composed of a hollow frame structure consisting of an upper frame piece 130, a lower frame piece 140, a left frame piece 150 and a right frame piece 160. The bottom of the lower frame piece is provided with an upper folding piece 141 folded upward, the right frame piece is provided with a left folding piece 161 folded leftward, and the left frame piece is provided with a left inserting piece 151. The number of the left opening slots is the same as that of the left folding slots. The number of pieces is consistent and their heights correspond one to one. The second connecting member includes a second pipe sleeve 210 fixed to the end of the ventilation pipe body and a second docking frame 220 integrally connected to the outer end of the second pipe sleeve. The second docking frame is also composed of a hollow frame structure consisting of an upper frame piece 230, a lower frame piece 240, a left frame piece 250, and a right frame piece 260. The top of the upper frame piece is provided with a lower folding piece 231 that folds downward, the left frame piece is provided with a right folding piece 251 that folds rightward, and the right frame piece is provided with a right insert piece 261. The number of right insert pieces is consistent with the number of right insert pieces and their heights correspond one to one. The number and distribution height of the left and right fold pieces are consistent, and the number of left and right fold pieces ranges from 2 to 4. It should be noted that the spacing between adjacent left or right fold pieces needs to be greater than the width of the left or right insert piece.

[0016] See Figure 3 、 Figure 4 and Figure 5The installation method of this embodiment is to first dock several ventilation duct bodies on the ground, then hoist the sections to the corresponding installation positions on the building for fixed installation. When docking two ventilation duct bodies, it is necessary to align the first connector of one ventilation duct body with the second connector of the other ventilation duct body. Then, lift the second connector so that the two connectors are staggered a certain distance up and down. At this time, the right folding piece on the second connector is entirely located above the left inserting piece on the first connector, and the right inserting piece on the second connector is entirely located above the left folding piece. Then, move the ventilation duct body so that the two adjacent first docking frames abut against the second docking frames. After releasing the folding piece, the second connector falls due to gravity, causing the right folding piece and the right inserting piece to simultaneously plug into the left inserting piece and the left folding piece. At the same time, the upper folding piece plugs into the lower frame piece, and the lower folding piece plugs into the upper frame piece, thus achieving a completely fixed connection between the first docking frame and the second docking frame. The width of the slots formed in all the folding pieces is adapted to the thickness of the corresponding inserting piece, ensuring that after plugging, the first docking frame and the second docking frame are tightly connected, ensuring airtightness of the docking. The narrower the width of the insert and flap, the smaller the lifting height of the second connector, making this embodiment easier to operate in a narrow space. However, the number of inserts and flaps needs to be increased to ensure the connection strength. The width of the left and right flaps in this embodiment ranges from 3 to 10 cm, preferably about 5 cm.

[0017] See Figure 2 A "mouth"-shaped docking surface is formed on the outer surface of the docking frame, and the docking surface is smooth. In order to enhance the airtightness of the docking point, grease can be applied to the docking surface, which not only improves the sealing of the docking, but also plays a lubricating role, thereby avoiding rust after long-term docking in this embodiment, which makes it difficult to separate.

[0018] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
