Description

TECHNICAL FIELD

[0001] The present application relates to the field of air duct installation, in particular to an air duct installation fixing structure. BACKGROUND

[0002] Air duct is a pipe system for air conveying and distribution. According to the cross-sectional shape, air ducts can be divided into circular air ducts, rectangular air ducts, flat round air ducts and the like. Among them, the circular air duct has the smallest resistance but the largest height size, and the production is complex, so the rectangular air duct is usually used as the main one. According to the material, the air duct can be divided into metal air duct, composite air duct and high polymer air duct.

[0003] In the related art, the installation of the air duct with a rectangular cross section is mainly connected with the top of the wall through a hanging bracket, and the end of the air duct is provided with a connecting flange. When the operator connects two adjacent air ducts, the airproof adhesive is usually applied on the connecting flange, and then the two connecting flanges are abutted, and finally the two adjacent air ducts are connected by using bolts.

[0004] For the above-mentioned related technology, the inventors find that when the air speed of the air duct increases, the load at the connection of the two air ducts increases, which easily causes the connection of the two air ducts to be loose, and the airproof adhesive is easily aged after long-term use, thereby causing the phenomenon of air leakage, so it needs to be improved.

[0047] The application will be further described below in conjunction with the accompanying drawings. Figures 1-10 The application will be further described below in conjunction with the accompanying drawings.

[0048] The embodiment of the application discloses a duct mounting and fixing structure. Referring to Figure 1 The duct mounting and fixing structure is used for reinforcing adjacent first and second ducts 1 and 2, and comprises a reinforcing assembly 3 and a control assembly 4 used for controlling the reinforcing assembly 3. The first duct 1 is connected to a wall top through a first support 11, and the second duct 2 is connected to the wall top through a second support 21. A support plate 5 is arranged on the first support 11 and the second support 21. The control assembly 4 and the reinforcing assembly 3 are connected to the support plate 5. A detection assembly 12 used for detecting wind speed is arranged on the first duct 1, and the detection assembly 12 cooperates with the control assembly 4. A first flange 13 is arranged on the first duct 1, and a second flange 22 is arranged on the second duct 2. The first flange 13 and the second flange 22 abut.

[0049] When the first and second ducts 1 and 2 are put into use, the detection assembly 12 detects the wind speed passing through the first and second ducts 1 and 2. At this time, the control assembly 4 controls the reinforcing assembly 3 according to the wind speed, and adjusts the clamping strength of the reinforcing assembly 3 on the first and second flanges 13 and 22, so as to realize the function of changing the reinforcing capacity of the reinforcing assembly 3 according to the wind speed, reduce the possibility of loosening between the first and second ducts 1 and 2 when the wind speed increases, and reduce the phenomenon of air leakage.

[0050] Referring to Figure 1 and Figure 2 The first and second ducts 1 and 2 are connected through bolts (not shown in the figure). In order to facilitate the operation personnel to connect the first and second ducts 1 and 2, the first and second flanges 13 and 22 are connected through pre-fixing assemblies 6. A group of pre-fixing assemblies 6 are arranged on one side of the first flange 13 close to the second flange 22 and one side of the second flange 22 close to the first flange 13.

[0051] The pre-fixing assembly 6 comprises a pre-fixing column 61, a pre-fixing plate 62 and a buckle 63. The pre-fixing plate 62 is rotationally connected to the pre-fixing column 61. Connection holes 64 are formed in the first and second flanges 13 and 22, and the pre-fixing column 61 and the pre-fixing plate 62 pass through the connection holes 64.

The end of the pull rope 164 away from the first roller 161 drives the sensing plate 151 to move towards the first pressure sensor 152, the first connecting spring 153 is in a compressed state, at this time, under the action of the first connecting spring 153, the possibility of the sensing plate 151 directly colliding with the first pressure sensor 152 is reduced, and the possibility of damage to the first pressure sensor 152 is reduced.

[0061] The electric push rod 41 moves the output end thereof according to the detection value of the first pressure sensor 152, at this time, the control rod 42 moves and drives the first control block 421 to move towards the first control column 432, when the first control inclined surface 422 contacts with the first control column 432, the first control column 432 moves along the first control inclined surface 422. The first control column 432 drives the first control plate 43 to move towards the corresponding reinforcing frame 31, the first control plate 43 drives the first rack 431 to move at the same time, the first rack 431 drives the control gear 45 to rotate, the control gear 45 drives the second control plate 44 to move towards the corresponding reinforcing frame 31. After the first control plate 43 and the second control plate 44 contact with the corresponding first reinforcing plate 32 and the second reinforcing plate 33, the first reinforcing plate 32 rotates towards the first flange 13, the second reinforcing plate 33 moves towards the second flange 22, and each reinforcing spring 34 is in a compressed state. Under the action of the elastic force of the reinforcing spring 34, the first reinforcing plate 32 and the second reinforcing plate 33 relatively stably limit the first flange 13 and the second flange 22, improve the connection stability between the first air pipe 1 and the second air pipe 2, and realize the function of changing the reinforcing intensity of the first reinforcing plate 32 and the second reinforcing plate 33 on the first air pipe 1 and the second air pipe 2 in real time according to the wind speed, and reduce the possibility of air leakage between the first air pipe 1 and the second air pipe 2.

[0062] Referring to Figure 6 and Figure 7In order to improve the limiting ability of the first reinforcing plate 32 and the second reinforcing plate 33 to the first air pipe 1 and the second air pipe 2, a damping groove 35 is formed on the side of the first reinforcing plate 32 close to the first flange 13 and the side of the second reinforcing plate 33 close to the second flange 22, a damping plate 36 is arranged in each damping groove 35, the damping plate 36 is connected with the groove bottom of the corresponding damping groove 35 through a damping spring 37, and the damping plate 36 is in sliding connection with the inner wall of the corresponding damping groove 35. The damping plate 36 corresponding to the first reinforcing plate 32 is in abutment with the first flange 13, and the damping plate 36 corresponding to the second reinforcing plate 33 is in abutment with the second flange 22.

[0063] When the first control plate 43 and the second control plate 44 control the corresponding first reinforcing plate 32 and the second reinforcing plate 33, the damping plate 36 is retracted into the corresponding damping groove 35, and the damping spring 37 is in a compressed state. At this time, under the action of the elastic force of the damping spring 37, the limiting ability of the damping plate 36 to the corresponding first flange 13 and the corresponding second flange 22 is improved. At the same time, the damping plate 36 and the damping spring 37 play a damping role, reducing the possibility of separation of the first reinforcing plate 32 and the second reinforcing plate 33 from the first air pipe 1 and the second air pipe 2 when the first air pipe 1 and the second air pipe 2 vibrate when the wind speed increases.

[0064] Referring to Figure 1 and Figure 3 When the wind flows from the second air pipe 2 into the first air pipe 1, a plurality of second air guide grooves 125 are formed on the side of the wind plate 121 close to the second air pipe 2, each second air guide groove 125 is inclined towards the central axis of the first air pipe 1 to guide the wind. A second pressure sensor 154 is embedded on the sensing seat 15, the second pressure sensor 154 is arranged on the side of the sensing plate 151 away from the first pressure sensor 152, the sensing plate 151 is connected with the second pressure sensor 154 through a second connecting spring 155, and the elastic potential energy of the first connecting spring 153 is greater than that of the second connecting spring 155.

[0065] Referring to Figure 5 , and the second control block 423 is fixed on the side of the control rod 42 away from the first control block 421, the second control plate 44 is fixed with a second control column 442 in the vertical direction, and the second control block 423 is provided with a second control inclined surface 424 matched with the second control column 442.

[0066] When the wind direction changes, the wind plate 121 rotates under the action of the second wind guide groove 125, and the wind plate 121 further drives the connecting disc 122, the connecting plate 123 and the connecting column 163 to rotate. At this time, the connecting column 163 rotates towards the direction close to the sensing seat 15. Since the elastic potential energy of the first connecting spring 153 is greater than that of the second connecting spring 155, the sensing plate 151 moves towards the second pressure sensor 154. The electric push rod 41 controls the output end thereof through the measurement value of the second pressure sensor 154, so that the control rod 42 drives the second control block 423 to move towards the second control column 442, so that the first control plate 43 and the second control plate 44 still control the first reinforcing plate 32 and the second reinforcing plate 33 according to the wind speed when the wind direction changes.

[0067] With reference to Figure 6 and Figure 8 , in order to further improve the connection stability between the first wind pipe 1 and the second wind pipe 2, a plurality of first support ribs 17 are arranged between the first flange 13 and the first wind pipe 1, and a plurality of second support ribs 23 are arranged between the second flange 22 and the second wind pipe 2.

A second moving spring 223 is arranged between the second moving block 222 and the inner wall of the corresponding second moving groove 221. A plurality of second sliding grooves 24 are arranged on the second wind pipe 2, and a second sliding block 241 is slidingly connected in each second sliding groove 24.

One end of the second support rib 23 is hingedly connected to the corresponding second moving block 222, and the other end is hingedly connected to the corresponding second sliding block 241.

[0070] With reference to Figure 6 and Figure 10 , the support plate 5 is provided with a first adjusting member 7 for controlling the movement of each first support rib 17 and a second adjusting member 8 for controlling the movement of each second support rib 23, the first control plate 43 is matched with the first adjusting member 7, and the second control plate 44 is matched with the second adjusting member 8.

The adjusting rod 71 corresponding to the first adjusting member 7 is rotationally connected with the inner wall of the first adjusting hole 51, and the adjusting rod 71 corresponding to the second adjusting member 8 is rotationally connected with the inner wall of the second adjusting hole 52.

[0073] When the first control plate 43 and the second control plate 44 move towards the corresponding reinforcing frame 31, the first control plate 43 and the second control plate 44 are in contact with the corresponding adjusting rod 71 synchronously, the adjusting rod 71 rotates and drives the corresponding adjusting plate 72 to move away from the support plate 5. The adjusting plate 72 moves with the corresponding first support rib 17 and the corresponding second support rib 23, so that the first support rib 17 and the second support rib 23 move away from the support plate 5. At this time, the first moving block 132 and the first sliding block 181 move, and the first moving spring 133 and the first sliding spring 182 are both in a compressed state; the second moving block 222 and the second sliding block 241 move, and the second moving spring 223 and the second sliding spring 242 are both in a compressed state, and the inclination angles of the first support rib 17 and the second support rib 23 are changed, thereby improving the support ability of the first support rib 17 to the first flanging 13 and the support ability of the second support rib 23 to the second flanging 22, that is, the connection stability between the first air pipe 1 and the second air pipe 2 is improved.
