Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, and more specifically, it relates to a shock-absorbing structure for ventilation pipes. Background Art

[0002] Ventilation ducts are often supported on the roof by hanging brackets. Generally, the hanging brackets usually use bolts to vertically extend into the roof wall body to form a connection with the wall body, so as to support the ventilation duct above the roof.

[0003] The hanging bracket generally forms a vertical and fixed connection with the wall body through bolts. When the ventilation duct shakes and drives the hanging bracket to shake, the stress of the bolts used to connect and fix the hanging bracket and the wall body on the wall body at the connection will increase, which is easy to damage the wall body, resulting in the bolts falling off from the wall body, increasing the possibility of the ventilation duct falling. Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a shock-absorbing structure for ventilation pipes, which reduces the risk of the ventilation duct falling from the roof of the house after shaking.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A shock-absorbing structure for ventilation pipes, including a pipe body and a hanging bracket for supporting the pipe body. The hanging bracket includes a support rod that fits the lower end of the pipe body. The support rod is perpendicular to the length direction of the pipe body, and hanging rods are arranged on both sides of the support rod. A connecting piece is arranged at the end of the hanging rod far away from the support rod. An installation plate is connected to the outside of the hanging rod through the connecting piece. One end of the installation plate facing the support rod is fixedly connected with a surrounding plate. The surrounding plate encloses a buffer groove. The connecting piece is placed in the buffer groove, and a shock-absorbing pad is arranged between the circumferential side of the connecting piece and the groove wall of the buffer groove.

[0006] The utility model is further provided as follows: The connecting piece includes a threaded pipe, a connecting ball, and a locking block whose central axes are on the same straight line. The connecting piece is threadedly connected with the hanging rod through the threaded pipe. The connecting ball is in the shape of a hemisphere and is fixedly connected to the end of the threaded pipe far away from the hanging rod. The locking block is fixedly connected to the end of the connecting ball far away from the threaded pipe.

[0007] The utility model is further provided as follows: The cross-section of the locking block is in the shape of a regular polygon.

[0008] The utility model is further provided as follows: One end of the surrounding plate facing the hanging rod is fixedly connected with a support plate. A spherical ring groove communicating with the buffer groove is opened on the support plate. The groove wall of the spherical ring groove corresponds to the shape of the connecting ball.

[0009] The present utility model is further configured such that at least a part of the connecting ball that penetrates through the end of the spherical ring groove away from the surrounding plate is placed outside the support plate.

[0010] The present utility model is further configured such that the shock-absorbing pad is made of a soft rubber pad, and the shock-absorbing pad is bonded to the groove wall of the buffer groove surrounded by the surrounding plate.

[0011] In summary, the present utility model has the following beneficial effects: Through the design of the connecting member and the buffer groove on the mounting plate, the hanging rod is stably supported on the top of the house. When the hanging rod shakes, the buffer effect of the shock-absorbing pad in the buffer groove reduces the pressure on the mounting plate during connection, thereby reducing the stress between the bolts fixing the hanging bracket and the roof wall, and ensuring the stable connection of the pipe body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0018] Embodiment: A shock-absorbing structure for a ventilation pipe, as Figures 1-4As shown in the figure, it includes a pipe body 1 and a hanger 2 for supporting the pipe body 1. The hanger 2 includes a support rod 21 that fits against the lower end of the pipe body 1. The support rod 21 is perpendicular to the length direction of the pipe body 1, and suspension rods 22 are provided on both sides of the support rod 21. A connecting piece 23 is provided at one end of the suspension rod 22 away from the support rod 21. An installation plate 24 is connected to the outside of the suspension rod 22 through the connecting piece 23. The installation plate 24 can be connected to the roof wall through bolts. One end of the installation plate 24 facing the support rod 21 is fixedly connected with a surrounding plate 241. The surrounding plate 241 encloses a buffer groove. The connecting piece 23 is placed in the buffer groove, and a shock-absorbing pad 243 is provided between the peripheral side of the connecting piece 23 and the groove wall of the buffer groove. The shock-absorbing pad 243 is made of a soft rubber pad and is bonded to the groove wall of the buffer groove enclosed by the surrounding plate 241. Through the setting of the buffer groove and the shock-absorbing pad 243, when the suspension rod 22 is driven by the pipe body 1 to shake, under the action of the shock-absorbing pad 243, the pressure between the connecting piece 23 and the installation plate 24 is reduced, thereby reducing the pressure of the bolt for connecting the installation plate 24 and the wall on the wall, and reducing the damage to the wall caused by the shaking of the pipe body 1 driving the connecting bolt, ensuring the stability of the connection between the hanger 2 and the wall.

[0019] As Figures 1-4 shown, the connecting piece 23 includes a threaded pipe 231, a connecting ball 232 and a locking block 233 whose central axes are on the same straight line. The connecting piece 23 is threadedly connected to the suspension rod 22 through the threaded pipe 231. The connecting ball 232 is in the shape of a hemisphere and is fixedly connected to the end of the threaded pipe 231 away from the suspension rod 22. The locking block 233 is fixedly connected to the end of the connecting ball 232 away from the threaded pipe 231. The design of the threaded pipe 231 facilitates the installation between the connecting piece 23 and the suspension rod 22, and also facilitates the installation connection among the installation plate 24, the connecting piece 23 and the suspension rod 22. The cross-section of the locking block 233 is a regular polygon, and correspondingly, the cross-section of the figure enclosed by the shock-absorbing pad 243 is also a regular polygon corresponding to the locking block 233. By the shock-absorbing pad 243 fitting and abutting against the locking block 233, after the suspension rod 22 is connected to the installation plate 24 through the connecting block, the suspension rod 22 will not rotate easily, ensuring the stable support of the suspension rod 22 for the support rod 21.

[0020] As Figures 1-4 shown, one end of the surrounding plate 241 facing the suspension rod 22 is fixedly connected with a support plate 242. A spherical ring groove communicating with the buffer groove is opened on the support plate 242. The groove wall of the spherical ring groove corresponds to the shape of the connecting ball 232. Through the support of the support plate 242, the suspension rod 22 installed with the connecting piece 23 is stably connected to the installation plate 24. At least a part of the connecting ball 232 passes through the end of the spherical ring groove away from the surrounding plate 241 and is placed outside the support plate 242. Through the design of this structure, when the connecting piece 23 is driven by the suspension rod 22 to shake, it is avoided that other parts in the connecting piece 23 abut against the support plate 242, resulting in damage between the connecting piece 23 or the installation plate 24.

[0021] Working principle: When the suspension rod 22 sways along with the pipe body 1, since the suspension rod 22 is supported under the roof through the mounting plate 24, the suspension rod 22 will sway at the connection between the mounting plate 24 and the suspension rod 22. The connection between the mounting plate 24 and the connecting piece 23 is realized by the support of the support plate 242 on the connecting ball 232. Also, because at least a part of the connecting ball 232 passes through the spherical ring groove and the end far away from the surrounding plate 241 is placed outside the support plate 242, the swaying of the suspension rod 22 will not cause direct collision between the connecting piece 23 and the support plate 242 to cause damage. Instead, the connecting ball 232 rubs against the groove surface of the spherical ring groove, minimizing the damage of the connecting piece 23 to the mounting plate 24 when the pipe body 1 sways. At the same time, due to the setting of the shock-absorbing pad 243 and the locking block 233, when the suspension rod 22 drives the connecting piece 23 to sway, the pressure of the locking block 233 on the surrounding plate 241 will be reduced under the action of the shock-absorbing pad 243, thereby reducing the damage of the bolts connecting the mounting plate 24 and the wall to the wall, ensuring the stability of the connection between the hanger 2 and the wall.

[0022] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
