Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a pipeline fixing structure for building heating and ventilation installation. Background Technique

[0002] The thickness and specification of the heating and ventilation pipeline can be variable according to requirements. Usually, when connecting, both ends of the air duct are always externally connected to fittings (such as elbows and reducers). Generally, there are no grooves at both ends of the heating and ventilation pipeline and it is equipped with sealing rings. The heating and ventilation pipeline has a very wide range of applications and can be used for the supply and return air ducts of purification systems, central air-conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mine gas drainage pipes, mine coated fabric air ducts, etc.

[0003] The utility model patent with the publication number of CN221221727U discloses a pipeline fixing structure for building heating and ventilation installation, belonging to the technical field of pipeline installation, to solve the problem that in the prior art, the inner diameter of the fixing device cannot be automatically adjusted according to the pipeline diameter to maintain a continuous squeezing force on the heating and ventilation pipeline. It includes a top plate, the lower surface of the top plate is fixedly connected with a U-shaped frame, and both sides of the lower surface of the top plate are threadedly penetrated with fixing bolts, and three fixing bolts are in a group and located on both sides of the U-shaped frame. The bottom inner wall of the U-shaped frame is fixedly connected with eight rotating shaft bases and two square frames; and the opposite sides of the eight rotating shaft bases in groups of two are rotationally connected through semi-circular pipe sleeves, and a buffer pad group is movably sleeved in the semi-circular pipe sleeves. A T-shaped seat is slidably connected inside the square frame.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 , the above technical solutions of the present invention will be described in detail through the following embodiments:

[0027] A pipeline fixing structure for building heating and ventilation installation, comprising: a top plate 1; a rectangular frame 2 is fixedly connected to the bottom of the top plate 1, two fixed plates 3 are arranged inside the rectangular frame 2, and two fixed boxes 4 are provided on the top of each fixed plate 3. A support frame 5 is fixedly connected to the bottom of the fixed box 4, and the bottom of the support frame 5 is fixedly connected to the rectangular frame 2 respectively; a clamping mechanism 6 for improving the installation stability of the heating and ventilation pipeline is arranged inside each fixed box 4; buffer mechanisms 7 that can be adjusted are arranged at the four corners of the top plate 1. The user inserts the heating and ventilation pipeline into the fixed box 4, and then clamps and fixes the heating and ventilation pipeline inserted into the fixed box 4 through the clamping mechanism 6, which can clamp and fix heating and ventilation pipelines with different diameters to achieve the purpose of installation.

[0028] Such as Figures 4 to 6As shown in the figure, the clamping mechanism 6 includes: an annular disk 8 is rotatably connected to the inside of the fixed box 4, and six moving blocks 9 are slidably connected to the fixed box 4 near the annular disk 8. A clamping jaw 10 is fixedly connected to the side of each moving block 9 away from the annular disk 8; a cylindrical block 11 is fixedly connected to the side of each moving block 9 near the annular disk 8. An arc-shaped groove 12 is formed in the annular disk 8 near the cylindrical block 11, and the arc-shaped groove 12 is adapted to the cylindrical block 11; a self-locking mechanism 13 for controlling the synchronous rotation of the annular disk 8 is arranged at the center of the inside of the fixed box 4. The user controls the synchronous rotation of the annular disk 8 inside the fixed box 4 through the self-locking mechanism 13. While the annular disk 8 rotates, the cylindrical block 11 is pushed through the arc-shaped groove 12, so that the cylindrical block 11 moves towards the center of the annular disk 8. While the cylindrical block 11 moves, it drives the moving block 9, and the moving block 9 moves through the cooperation of the fixed box 4. While the moving block 9 moves, it drives the clamping jaw 10, so that the six clamping jaws 10 cooperate to clamp and fix the HVAC pipeline at the same time, achieving the purpose of installation, and the HVAC pipeline with different diameters can be firmly fixed inside the device, avoiding the phenomenon that the external part of the device is collided, resulting in the HVAC pipeline shaking inside the device, solving the problem that the existing pipeline fixing structure for building HVAC installation wraps and fixes the pipeline through the self-weight of the HVAC pipeline, but when the external part of the device is collided, the pressure of the HVAC pipeline on the device weakens, and at the same time, the clamping force of the semi-circular pipe sleeve on the pipeline also weakens, resulting in unstable clamping of the HVAC pipeline and shaking inside the device.

[0029] As Figure 2 and Figure 3 shown, the self-locking mechanism 13 includes: a worm 14 is arranged at the center of the inside of the fixed box 4. A rotating shaft 15 is fixedly connected to the center of the worm 14. The top end of the rotating shaft 15 is rotatably connected to the top plate 1, and the bottom end of the rotating shaft 15 penetrates through the rectangular frame 2 and extends to the knob 16. The knob 16 is fixedly connected to the rotating shaft 15. A silica gel pad 17 with concave and convex patterns on the surface is arranged on the outer surface of the knob 16, and the silica gel pad 17 is fixedly connected to the knob 16; a worm gear 18 is meshed on both sides of the worm 14. A hollow tube 19 is fixedly connected to the center of each worm gear 18. Both ends of the hollow tube 19 penetrate through the fixed box 4 and extend to the annular disk 8. The annular disk 8 is fixedly connected to the hollow tube 19 respectively. The user rotates the knob 16, the knob 16 drives the rotating shaft 15, and the rotating shaft 15 drives the worm 14 to rotate. While the worm 14 rotates, it drives the two worm gears 18 on both sides to rotate synchronously. While the worm gears 18 rotate, they drive the hollow tubes 19 respectively, and the hollow tubes 19 drive the annular disk 8, so that the annular disks 8 inside the device rotate synchronously, and the cooperation between the worm 14 and the worm gears 18 can also achieve the self-locking function.

[0030] As Figure 5 and Figure 6As shown, sliding grooves 20 are formed on both sides of the moving block 9, and limiting sliding bars 21 are fixedly connected to the fixing box 4 near the sliding grooves 20. The moving block 9 is slidably connected to the limiting sliding bars 21 through the sliding grooves 20, which can limit the moving block 9 and enable the moving block 9 to slide flexibly inside the fixing box 4.

[0031] As Figure 1 and Figure 2 As shown, the buffer mechanism 7 includes: through holes are formed at the four corners of the top plate 1, screw rods 22 are arranged inside the through holes, mounting plates 23 are fixedly connected to the tops of the screw rods 22, and four mounting holes 24 are formed inside the mounting plates 23; limiting plates 25 are fixedly connected to the bottoms of the screw rods 22, springs 26 are arranged between the limiting plates 25 and the top plate 1, the springs 26 are respectively sleeved on the outer surfaces of the screw rods 22, adjusting nuts 27 are arranged at the four corners of the top of the top plate 1, the adjusting nuts 27 are threadedly connected to the screw rods 22 respectively, rubber pads are fixed to the bottoms of the adjusting nuts 27. When the outside of the device is collided, the device moves downward due to its own gravity, driving the top plate 1. The top plate 1 moves downward on the surface of the screw rod 22. While the top plate 1 moves, the springs 26 are compressed through the cooperation of the limiting plates 25. The springs 26 buffer the device through their own elasticity. The user can rotate the adjusting nuts 27 to make the adjusting nuts 27 move up and down on the surface of the screw rods 22, so as to adjust the distance between the top plate 1 and the limiting plates 25, and further achieve the purpose of adjusting the softness and hardness of the springs. It can not only buffer the release of force on the HVAC pipeline when the outside of the device is collided, but also adjust the buffer performance inside the device according to the needs of the user, improving the practicability of the pipeline fixing structure for building HVAC installation.

[0032] As Figure 1 As shown, mounting bolts 28 are arranged at the four corners of the top of the fixing plate 3. The bottoms of the mounting bolts 28 penetrate through the fixing plate 3 and extend into the inside of the rectangular frame 2. The mounting bolts 28 are threadedly connected to the rectangular frame 2, which not only facilitates the user to install the device, but also improves the stability of the device after installation.

[0033] As Figure 5 As shown, damping pads 29 are arranged on one side of the clamping jaws 10 close to the center of the fixing box 4. The damping pads 29 are fixedly connected to the clamping jaws 10 respectively, increasing the friction force of the contact surface between the clamping jaws 10 and the HVAC pipeline, and thus improving the stability of the HVAC pipeline installation.

[0034] Working principle: The user rotates the knob 16, the knob 16 drives the rotating shaft 15, the rotating shaft 15 drives the worm 14 to rotate. While the worm 14 rotates, it drives the two-sided worm wheels 18 to rotate synchronously. While the worm wheels 18 rotate, they drive the hollow tubes 19 respectively. The hollow tubes 19 drive the annular disc 8, so that the annular disc 8 inside the device rotates synchronously. And the cooperation between the worm 14 and the worm wheels 18 can also achieve the function of self-locking. While the annular disc 8 rotates, it pushes the cylindrical block 11 through the arc-shaped groove 12, so that the cylindrical block 11 moves towards the center of the annular disc 8. While the cylindrical block 11 moves, it drives the moving block 9. The moving block 9 moves through the cooperation of the fixed box 4. While the moving block 9 moves, it drives the clamping jaws 10, so that the six clamping jaws 10 cooperate to clamp and fix the HVAC pipeline at the same time, achieving the purpose of installation. HVAC pipelines with different diameters can be firmly fixed inside the device, avoiding the phenomenon that the external part of the device is collided, resulting in the HVAC pipeline shaking inside the device. It solves the problem that the existing pipeline fixing structure for building HVAC installation uses the gravity of the HVAC pipeline itself to control the semi-circular pipe sleeve to wrap and fix the pipeline. However, when the external part of the device is collided, the pressure of the HVAC pipeline on the device weakens, and at the same time, the clamping force of the semi-circular pipe sleeve on the pipeline also weakens, resulting in unstable clamping of the HVAC pipeline and shaking inside the device.

[0035] When the external part of the device is collided, the device moves downward due to its own gravity and drives the top plate 1. The top plate 1 moves downward on the surface of the screw rod 22. While the top plate 1 moves, it squeezes the spring 26 through the cooperation of the limiting plate 25. The spring 26 buffers the device through its own elasticity. The user can rotate the adjusting nut 27, so that the adjusting nut 27 moves up and down on the surface of the screw rod 22, achieving the purpose of adjusting the distance between the top plate 1 and the limiting plate 25, and further achieving the purpose of adjusting the soft hardness of the spring. It can not only relieve the force and buffer the HVAC pipeline when the external part of the device is collided, but also adjust the buffering performance inside the device according to the needs of the user, improving the practicability of the pipeline fixing structure for building HVAC installation.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
