Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fixing technology, specifically to a heating, ventilation and air conditioning (HVAC) pipe fixing device. Background Technology
[0002] In existing HVAC duct fixing technologies, most fixing devices use rigid structures to fix the ducts.
[0003] When faced with the thermal expansion and contraction of HVAC ducts due to temperature changes, these rigid fixing devices cannot provide space for the duct to deform when it expands due to heat. This results in a great deal of compressive and binding force on the duct. Under this condition for a long time, the duct is very prone to deformation due to uneven pressure, and in severe cases, it may even break. In addition, the rigid fixing device itself will be excessively stretched when the duct expands, which can easily damage its fixing structure and reduce the service life of the fixing device.
[0004] When the pipe temperature drops and it contracts, gaps will appear between the rigid fixing device and the pipe, causing the pipe to lose effective fixed support and making it prone to shaking under the action of external forces such as fluid impact.
[0005] Therefore, we propose a fixing device for HVAC pipes. Utility Model Content
[0006] The purpose of this utility model is to provide a fixing device for HVAC pipes to solve the above-mentioned shortcomings in the technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a heating, ventilation, and air conditioning (HVAC) pipe fixing device, comprising two arc-shaped sponge columns, wherein two first arc-shaped steel frames and two second arc-shaped steel frames are respectively embedded inside the two arc-shaped sponge columns, and the outer walls at both ends of the two arc-shaped sponge columns are provided with connecting plates. The outer walls at both ends of the two first arc-shaped steel frames and the outer walls at both ends of the two second arc-shaped steel frames are fixedly connected to the outer walls of the connecting plates. The outer walls of the connecting plates are provided with connecting holes, and the inner walls of the connecting holes are equipped with matching bolts. The outer walls of the two arc-shaped sponge columns are fitted with equidistantly distributed fan-shaped fixing blocks, and there is a gap between adjacent fan-shaped fixing blocks, the gap being 4-5mm.
[0008] Preferably, a vertically downward support rod is fixedly welded to the center of the bottom of each of the two first arc-shaped steel frames.
[0009] Preferably, a mounting block is fixed to one bottom end of each of the two support rods by welding, and a base is placed at the bottom of the mounting block.
[0010] Preferably, the top outer wall of the mounting block has two mating grooves, and the top outer wall of the base is fixed with two vertically upward mating blocks by welding. The outer wall contour of the mating block matches the inner wall contour of the mating groove. One side outer wall of the mounting block has a first insertion hole that penetrates the mating groove, and the outer wall of the mating block has a second insertion hole. The central axis of the second insertion hole and the first insertion hole are on the same straight line, and the diameter of the second insertion hole is equal to that of the first insertion hole.
[0011] Preferably, a permanent magnet is fixedly provided at the center of the first socket, and metal rods are inserted into the outer walls of both ends of the first socket. One end of each of the two metal rods passes through the inner wall of the second socket and is attracted to the outer wall of the permanent magnet.
[0012] Preferably, the base has four equally spaced fixing holes at its bottom corners, and the inner walls of the fixing holes are fitted with matching bolts.
[0013] Preferably, the two first arc-shaped steel frames and the two second arc-shaped steel frames are made of spring steel.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: With the fan-shaped connecting plates fitted onto the outer walls of the two arc-shaped sponge columns, the two arc-shaped sponge columns outside the pipe can deform to a certain extent as the pipe expands due to their good flexibility and elasticity. This will not exert excessive squeezing or binding force on the pipe, and will avoid the pipe being deformed or even ruptured due to rigid fixation.
[0015] The 4-5mm gap between adjacent fan-shaped fixing blocks ensures that the present invention will not be excessively stretched or damaged due to pipe expansion. When the pipe temperature drops and shrinks, the arc-shaped sponge column, together with the first arc-shaped steel frame and the second arc-shaped steel frame, will rely on its own elasticity to shrink back and always fit tightly against the pipe surface, preventing the pipe from shaking due to gaps between the pipe and the fixing device.

Connecting holes 5 are opened on the outer walls of the connecting plates 4, and bolts compatible with the connecting holes 5 are provided. Equally spaced fan-shaped fixing blocks 6 are fitted onto the outer walls of the two arc-shaped sponge columns 1, leaving a gap of 4-5 mm between adjacent fan-shaped fixing blocks 6.
[0022] Example 2 Based on Embodiment 1, vertically downward support rods 7 are welded and fixed at the bottom center of the two first arc-shaped steel frames 2. Mounting blocks 8 are welded and fixed at one bottom end of the two support rods 7. Mounting blocks 8 are equipped with bases 9. Two mating grooves 10 are formed on the top outer wall of the mounting blocks 8. Two vertically upward mating blocks 11 are welded and fixed to the top outer wall of the base 9. The outer contour of the mating blocks 11 matches the inner contour of the mating grooves 10. A first insertion hole 12 penetrating the mating groove 10 is formed on one side of the outer wall of the mounting block 8. A second insertion hole 14 is formed on the outer wall of the mating blocks 11, allowing the second insertion hole 14 to... The central axes of the first insertion holes 12 are on the same straight line and have the same diameter. A permanent magnet 13 is fixedly installed in the center of the first insertion hole 12.

[0023] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-8In use, this invention involves first placing two arc-shaped sponge columns 1 around the outside of the HVAC pipe to be fixed, positioning the pipe within the space enclosed by the two arc-shaped sponge columns 1. The fan-shaped connecting plates 6 on the outer walls of the arc-shaped sponge columns 1 are then fitted into the pipe. The connecting plates 4 are located at the outer ends of the two arc-shaped sponge columns 1. Bolts are passed through the connecting holes 5 on the outer walls of the connecting plates 4 and tightened to connect the two arc-shaped sponge columns 1 together, clamping the pipe. The pipe is held in place by the adjacent fan-shaped fixing blocks 6. The 5mm gap, combined with the arc-shaped sponge column 1, can adapt to the deformation of the pipe. Using bolts that match the four corner fixing holes 16 at the bottom of the base 9, the base 9 is installed in the predetermined installation position. Then, the mounting block 8 at the bottom of the support rod 7 welded to the center of the bottom of the two first arc-shaped steel frames 2 is connected to the base 9. The connecting block 11 welded to the outer wall of the top of the base 9 is inserted into the connecting groove 10 on the outer wall of the top of the mounting block 8, so that the first insertion hole 12 is aligned with the second insertion hole 14. Then, the metal insertion rod 15 is passed through the first insertion hole 12 and the second insertion hole 14, so that one end is attracted to the permanent magnet 13 at the center of the first insertion hole 12, thus completing the connection between the mounting block 8 and the base 9.
