Description

Technical Field

[0001] The utility model relates to the technical field of air duct support and hanger brackets, in particular to an earthquake-resistant air duct support and hanger bracket. Background Art

[0002] Supports and hangers are the collective name for brackets and hangers. They bear the weight of various accessories and their media, constrain and limit the unreasonable displacement of building components, and control the vibration of components in various construction links. They play an extremely important role in the safe operation of building facilities. Supports and hangers are mainly used in mechanical and electrical engineering facilities such as building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications;

[0003] For example, the public document: CN215981406U, named "A mechanical and electrical air duct hanger fixing device", includes a hanger plate, an upper hanging beam fixed to the bottom of the hanger plate, a lower hanging beam arranged below the upper hanging beam and a hanger rod rotatably arranged on both sides of the bottom surface of the hanger plate, fixed seats are provided on both sides of the top of the hanger plate, stabilizing tubes are provided at both ends of the upper hanging beam and the lower hanging beam, and a transmission assembly for the rotation of the hanger rod is provided in the hanger plate; an anti-seismic mechanism for the installation of the hanger plate is provided on the fixed seat; the utility model has a simple structure, and through the cooperation of the anti-seismic mechanism and the side pull rod, it is convenient to increase the stability of the mechanical and electrical air duct after fixation, and at the same time avoid the hanger shaking due to collision after the installation of the mechanical and electrical air duct, thereby avoiding the damage of the fixing point of the hanger plate; effectively improves the safety of the mechanical and electrical air duct after installation.

[0004] The above-mentioned existing duct anti-seismic support and hanger bracket uses an L-shaped piece to fix the duct on the bracket. When vibration occurs in the left and right directions, the structure is prone to collision and pulling. As the number of vibrations increases, it is easy to cause the connection to loosen over a long period of time, affecting the stability of the duct. When the L-shaped piece loosens and the duct is no longer restricted, the user cannot quickly know it, which poses a safety hazard. Therefore, it does not meet the existing needs. We have proposed an anti-seismic duct support and hanger bracket. Utility Model Content

[0005] The purpose of the utility model is to provide an earthquake-resistant air duct support and hanger bracket which can reduce the vibration force at the air duct fixing point and has a reminder function, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an earthquake-resistant air duct support and hanger, comprising a bottom bracket, a top frame is provided above the bottom bracket, a screw is installed between the top frame and the bottom bracket, and the screw is located on both sides of the bottom bracket and the top frame, and the air duct is installed between the bottom bracket and the top frame;

[0007] Also includes:

[0008] An assembly groove is provided on the outer wall of the adjacent surface of the bottom bracket and the top bracket, and two L-shaped stoppers are installed inside each of the assembly grooves, and the L-shaped stoppers are used to position the air duct;

[0009] A shock absorbing component is mounted on the outer wall of the L-shaped limiter, the shock absorbing component comprises a damping spring which is arranged symmetrically on both sides, a limit plate is mounted on one end of the damping spring, a rubber anti-slip block is bonded to the outer wall of the limit plate, and a pressure sensor is mounted in a groove at the middle position of the rubber anti-slip block for detecting the tightness of the fit between the L-shaped limiter and the air duct;

[0010] The controller is mounted on the outer wall of the front end surface of the bottom bracket, the controller includes a wireless transmission module, and the controller is wirelessly connected to the user terminal through the wireless transmission module, and the input end of the controller is wirelessly connected to the output end of the pressure sensor.

[0011] Preferably, a plurality of assembly holes are arranged on the inner wall of the assembly groove in a transversely spaced arrangement, and the L-shaped limiter is assembled and installed in combination with the assembly holes of the assembly groove by means of bolts.

[0012] Preferably, support hangers are installed on both sides above the top frame, and the upper end of the screw extends through to the top of the support hanger.

[0013] Preferably, a plurality of oblique hangers are installed on the outer wall of the supporting hanger, and the angle between the oblique hangers and the supporting hanger is 45°.

[0014] Preferably, a plurality of slots are arranged vertically at intervals on the outer wall of the support hanger, and an assembly is provided at one end of the oblique hanger close to the support hanger, and a plurality of combination holes are opened on the outer wall of the assembly, and the combination holes are assembled and combined with the slots by bolts.

[0015] Preferably, a positioning seat is integrally provided at one end of the oblique hanger away from the supporting hanger, a fixing bolt is installed on the lower surface of the positioning seat, and the positioning seat is assembled and installed with the wall through the fixing bolt.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model can effectively reduce the vibration from the left and right directions through the arrangement of the assembly groove, L-shaped limiter, shock absorbing assembly, damping spring, rubber anti-sliding block, pressure sensor, controller, and wireless transmission module, making the air duct and the L-shaped limiter more stable, and also has a detection reminder function, so that the user terminal can know in real time whether the structure is normal, thereby improving safety;

[0018] Specifically, the assembly groove is set to reduce the weight of the bottom bracket and the top frame, and an L-shaped limiter is installed inside. A shock-absorbing assembly is installed at the L-shaped limiter, and the air duct is located between the shock-absorbing assemblies. When the air duct vibrates left and right, the damping spring reduces the impact of vibration on the air duct. Compared with a rigid connection, it is more shock-resistant. When placed in daily life, the rubber anti-sliding block is in contact with the side wall of the air duct, and the pressure sensor detects the pressure change and feeds back the signal to the controller. The controller then feeds back the signal to the user terminal through the wireless transmission module, so that the user terminal knows that the air duct and the pressure sensor are in a contact state. When the pressure sensor is separated from the air duct, the signal is fed back to the controller, and the controller sets the separation time. When the separation time is less than the set value, the controller will not transmit a reminder. When the separation time is greater than the set value, the controller will wirelessly transmit a reminder to the user terminal, so that the user knows that the air duct is separated from the L-shaped limiter and the place is inspected.

[0019] The problem that the air duct is fixed to the bracket on the existing air duct anti-seismic support and hanger bracket by an L-shaped piece is solved. When vibration occurs in the left and right directions, the structure is prone to collision and pulling. As the number of vibrations increases, it is easy to cause the connection to loosen over a long period of time, affecting the stability of the air duct. Moreover, when the L-shaped piece becomes loose and the air duct is no longer restricted, the user cannot quickly know the problem, which poses a safety hazard.

[0020] 2. Multiple oblique hangers are distributed on different surfaces of two supporting hangers and form oblique angles, so that after the installation of the duct support hanger, the oblique hangers located in different directions can play the role of oblique bracing, which can effectively resist vibrations in different directions and improve the seismic resistance of the support hanger; through the alignment of the slot holes and the combination holes, the assembly and the supporting hanger can be assembled and installed together by bolts, and the slot holes arranged at intervals vertically can facilitate the user to adjust the height of the assembly on the supporting hanger according to on-site installation requirements.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-5 The utility model provides an embodiment: an earthquake-resistant air duct support and hanger, comprising a bottom bracket 1, a top frame 2 is provided above the bottom bracket 1, a screw 3 is installed between the top frame 2 and the bottom bracket 1, and the screw 3 is located on both sides of the bottom bracket 1 and the top frame 2, and the air duct is installed between the bottom bracket 1 and the top frame 2;

[0029] Also includes:

[0030] The assembly groove 5 is formed on the outer wall of the adjacent surface of the bottom bracket 1 and the top bracket 2. Two L-shaped stoppers 7 are installed inside each assembly groove 5. The L-shaped stoppers 7 are used to position the air duct;

[0031] A shock absorbing assembly 8 is mounted on the outer wall of the L-shaped stopper 7. The shock absorbing assembly 8 includes a damping spring 9 that is symmetrically arranged on both sides. A stopper plate 10 is mounted on one end of the damping spring 9. A rubber anti-slip block 11 is bonded to the outer wall of the stopper plate 10. A pressure sensor 19 is mounted in a groove at the middle position of the rubber anti-slip block 11 for detecting the tightness of the fit between the L-shaped stopper 7 and the air duct.

[0032] The controller 4 is mounted on the outer wall of the front end surface of the bottom bracket 1. The controller 4 includes a wireless transmission module 20. The controller 4 is wirelessly connected to the user terminal through the wireless transmission module 20. The input end of the controller 4 is wirelessly connected to the output end of the pressure sensor 19.

[0033] Through the arrangement of the assembly groove 5, the L-shaped limiter 7, the shock absorbing assembly 8, the damping spring 9, the rubber anti-sliding block 11, the pressure sensor 19, the controller 4, and the wireless transmission module 20, the vibration from the left and right directions can be effectively reduced, so that the air duct and the L-shaped limiter 7 are more stable, and the detection reminder function is also provided, so that the user terminal can know in real time whether the structure is normal, thereby improving safety;

[0034] Specifically, the assembly groove 5 is provided to reduce the weight of the bottom bracket 1 and the top bracket 2, and an L-shaped limiter 7 is installed inside. A shock absorbing assembly 8 is installed at the L-shaped limiter 7, and the air duct is located between the shock absorbing assemblies 8. When the air duct vibrates left and right, the damping spring 9 reduces the impact of the vibration on the air duct. Compared with a rigid connection, it is more shock-resistant. When placed in daily life, the rubber anti-slip block 11 is in contact with the side wall of the air duct, increasing the friction with the air duct and improving the anti-slip effect. The pressure sensor 19 detects the pressure change and feeds back the signal to the controller 4. The controller 4 then feeds back the signal to the user terminal through the wireless transmission module 20, so that the user terminal knows that the air duct and the pressure sensor 19 are in contact.

[0035] The main principle of the pressure sensor 19 detecting pressure changes is as follows: in the normal placement state, the pressure sensor 19 is close to the side wall of the air duct, in which state the pressure sensor 19 is under pressure;

[0036] After the air duct is separated from the pressure sensor 19, the pressure sensor 19 is in a non-pressurized state, and the pressure has changed compared with the previous pressure;

[0037] The user can know whether the pressure sensor 19 is in contact with the air duct by checking whether the pressure sensor 19 is in a pressurized state.

[0038] When the pressure sensor 19 is separated from the air duct, a feedback signal is sent to the controller 4, and the controller 4 sets the separation time. When the separation time is less than the set value, the controller 4 will not transmit a reminder. When the separation time is greater than the set value, the controller 4 will wirelessly transmit a reminder to the user terminal, so that the user knows that the air duct is separated from the L-shaped limiter 7 and repairs the place.

[0039] See also Figure 2 A plurality of assembly holes 6 are arranged on the inner wall of the assembly groove 5 in a transversely spaced arrangement, and the L-shaped stopper 7 is assembled and installed with the assembly holes 6 of the assembly groove 5 by means of bolts;

[0040] The assembly holes 6 arranged at intervals in the transverse direction can facilitate the user to adjust and install the L-shaped limiter 7 to a desired position according to the size of the air duct to be assembled.

[0041] See also Figure 1 , support hangers 12 are installed on both sides above the top frame 2, and the upper end of the screw rod 3 extends through to the top of the support hanger 12;

[0042] The top end of the screw rod 3 is passed through the upper part of the support hanger 12 , so that the top frame 2 , the support hanger 12 , and the bottom bracket 1 are installed together and hung under the wall through the screw rod 3 .

[0043] See also Figure 1 , Figure 2, a plurality of oblique hangers 16 are mounted on the outer wall of the support hanger 12, and the angle between the oblique hangers 16 and the support hanger 12 is 45°;

[0044] Multiple oblique hangers 16 are distributed on different surfaces of the two supporting hangers 12 and form an oblique inclination angle, so that after the air duct support hanger is installed, the oblique hangers 16 located in different directions play the role of oblique support, which can effectively resist vibrations in different directions and improve the seismic resistance of the support hanger.

[0045] See also Figure 1 A plurality of slots 13 are arranged vertically and spaced apart on the outer wall of the support hanger 12, and a combination piece 14 is provided at one end of the oblique hanger 16 close to the support hanger 12, and a plurality of combination holes 15 are provided on the outer wall of the combination piece 14, and the combination holes 15 are assembled and combined with the slots 13 by bolts;

[0046] By aligning the slots 13 with the combination holes 15, the assembly 14 can be assembled and installed together with the support bracket 12 by bolts. The slots 13 arranged at intervals vertically can facilitate the user to adjust the height of the assembly 14 on the support bracket 12 according to on-site installation requirements.

[0047] See also Figure 2 , a positioning seat 17 is integrally provided at one end of the oblique hanger 16 away from the supporting hanger 12, a fixing bolt 18 is installed on the lower surface of the positioning seat 17, and the positioning seat 17 is assembled and installed with the wall through the fixing bolt 18;

[0048] The positioning seat 17 and the oblique hanger 16 are integrally constructed, and the positioning seat 17 is fixed to the wall using fixing bolts 18, which can reduce the difficulty of on-site assembly at this location.

[0049] Working principle: When in use, hang the top of the screw rod 3 on the wall, install the support hanger 12 on the screw rod 3, install the bottom bracket 1 of the air duct and the top bracket 2 at the bottom, adjust the distance between the bottom bracket 1 and the top bracket 2 of the air duct to adapt the distance to the size of the air duct, install the air duct between the bottom bracket 1 and the top bracket 2, install the L-shaped limiter 7 at the required position in the assembly groove 5 according to the size of the air duct, make the L-shaped limiter 7 located on both sides of the air duct, adjust the oblique hanger 16 to a suitable height, install it on the outer wall of the support hanger 12 at the height, and fix the positioning seat 17 to the wall through the fixing bolts 18;

[0050] During daily placement, the oblique hanger 16 resists vibrations from all directions, and the vibrations in the left and right directions are weakened by the damping spring 9 of the shock absorbing assembly 8;

[0051] The rubber anti-slip block 11 is in contact with the side wall of the air duct, increasing the friction with the air duct and improving the anti-slip effect. The pressure sensor 19 detects the pressure change and feeds back the signal to the controller 4. The controller 4 then feeds back the signal to the user terminal through the wireless transmission module 20, so that the user terminal knows that the air duct and the pressure sensor 19 are in a state of contact. When the pressure sensor 19 is separated from the air duct, the signal is fed back to the controller 4. The controller 4 sets the separation time. When the separation time is less than the set value, the controller 4 will not transmit a reminder. When the separation time is greater than the set value, the controller 4 will wirelessly transmit a reminder to the user terminal, so that the user knows that the air duct is separated from the L-shaped limiter 7 at that location and performs maintenance at that location.
