Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a sound-insulating PVC pipe. Background Art

[0002] The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC pipe is made of polyvinyl chloride resin combined with stabilizers, lubricants, etc. and then melt extruded. It is the earliest plastic pipe developed and applied, and is used for water supply and drainage, sheath pipes, etc. The existing PVC pipe fixing method generally uses the high temperature of a hot melt gun to melt the PVC pipe, splicing one end of the melted PVC pipe with another PVC pipe, and fixing the two pipes after the PVC pipe solidifies. Although this method can fix the PVC pipe, this connection method has high requirements on the operator and is not convenient for the installation and fixation of the PVC pipe. Once the PVC pipe is damaged and needs to be replaced, the PVC pipe needs to be completely removed, which will cause a waste of resources.

[0003] To solve the above problems, a Chinese patent discloses a steel belt reinforced PVC pipe (Announcement No.: CN112066099B), which is provided with a fixing device on the outside of the pipe, and a block is slidably connected to the inner cavity of the fixing device. The first and second cross bars are respectively fixed on the left and right sides of the block, and a curved plate is rotatably connected to one end of the second cross bar.

The first bent plate is connected to another PVC pipe, and the two PVC pipes are connected, spliced ​​and fixed, which is easy to operate.

[0004] The existing patent provides a solution to the above problem, but the PVC pipe may vibrate during use, causing slight vibrations between the curved plate and the first bent plate. Long-term use may cause an offset between the two PVC pipes, leading to serious leakage at the pipe joints, resulting in a waste of resources.

[0005] In view of this, in view of the above-mentioned deficiencies, the utility model improves and optimizes the PVC pipe in the prior art and develops a sound-insulating PVC pipe. Summary of the invention

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 6 , the utility model provides a technical solution:

[0029] A soundproof PVC pipe comprises a first pipe body 1 and a second pipe body 2, wherein a fixing piece 3 is fixedly connected to the outer surface of the first pipe body 1, a connecting piece 4 is fixedly connected to the outer surface of the second pipe body 2, a plurality of clamping grooves 9 are equidistantly provided in the inner cavity of the fixing piece 3, a plurality of connecting grooves 15 are equidistantly provided in the inner cavity of the connecting piece 4, a connecting plate 16 is hingedly provided in the inner cavity of the connecting groove 15, a rotating spring 17 is fixedly connected to the bottom of the connecting plate 16, the other end of the rotating spring 17 is fixedly connected to the inner cavity of the connecting groove 15, the connecting piece 4 can be clamped into the gap between the fixing piece 3 and the first pipe body 1, the connecting piece 4 is movably connected to the inner surface of the fixing piece 3, and the fixing piece 3 It is fixed to the connecting member 4 by a fixing device 6, a connecting groove 10 is provided in the inner cavity of the fixing member 3, and a plurality of fixing grooves 11 are equidistantly provided in the inner cavity of the connecting member 4, each fixing groove 11 is located at the circumferential center of the two connecting grooves 15, and the connecting groove 10 is located at the circumferential center of the two clamping grooves 9, a sliding plate 8 is slidably connected to the inner cavity of the fixing device 6, a baffle 13 is provided on one side of the sliding plate 8, a return spring 14 is fixedly connected to one side of the baffle 13, and the other end of the return spring 14 is fixedly connected to the inner cavity of the fixing device 6, a bolt 7 is tightly provided on the top of one side of the fixing device 6, and one end of the bolt 7 passes through the fixing device 6 and contacts with the fixing member 3.

[0030] By adopting the above technical solution, when the operator needs to fix the first tube body 1 and the second tube body 2, the connecting piece 4 is inserted into the gap between the fixing piece 3 and the first tube body 1, so that the inner wall of the fixing piece 3 contacts one end of the connecting piece 4. At this time, the first tube body 1 and the second tube body 2 are in contact with each other, and the operator rotates the second tube body 2, and the second tube body 2 drives the connecting piece 4 to rotate, and the connecting piece 4 drives the connecting plate 16 and the rotating spring 17 to rotate synchronously. The connecting plate 16 in the inner cavity of the connecting piece 4 is restricted by the inner wall of the fixing piece 3, so that the connecting plate 16 is retracted into the connecting groove 15 and squeezes the rotating spring 17. When the connecting plate 16 corresponds to the clamping groove 9, the connecting plate 16 can be reset and pushed into the clamping groove 9 by the rotating spring 17. At this time, the first tube body 1 and the second tube body 2 are clamped and fixed, and the operator presses the sliding plate 8. The sliding plate 8 pushes the baffle 13 to move so that the bottom of the baffle 13 no longer extends out of the bottom outside of the fixing device 6. The baffle 13 squeezes the reset spring 14. The operator puts the bottom of the fixing device 6 into the connecting groove 10 and moves axially along the connecting groove 10 until the bottom of the fixing device 6 contacts the inner cavity of the connecting member 4. The sliding plate 8 is released to reset the reset spring 14 and push the baffle 13 out. The baffle 13 is snapped into the fixing groove 11 to prevent the fixing member 3 and the connecting member 4 from rotating and deviating, and to avoid unstable connection between the first tube body 1 and the second tube body 2 and leakage. The operator turns the bolt 7 again to tightly set the fixing device 6 on the outer surface of the fixing member 3 to prevent people from accidentally touching the sliding plate 8, which causes loosening and leakage between the two tube bodies, so that the first tube body 1 and the second tube body 2 are fixed more tightly.

[0031] Specifically, Figure 1 As shown, the inner sides of the circumferences of the first tube body 1 and the second tube body 2 are fixedly connected with rubber pads 19, the inner sides of the circumferences of the rubber pads 19 are fixedly connected with sound insulation pads 20, and the opposite surfaces of the first tube body 1 and the second tube body 2 are fixedly connected with sealing pads 5.

[0032] By adopting the above technical solution, the rubber pad 19 can reduce the vibration between the first tube body 1 and the second tube body 2 during operation, and reduce damage to the connecting device of the first tube body 1 and the second tube body 2. The sound insulation pad 20 can reduce the noise generated during the operation of the first tube body 1 and the second tube body 2. The sealing pad 5 can prevent liquid from leaking from the connection between the first tube body 1 and the second tube body 2.

[0033] Specifically, Figure 4 , Figure 5 As shown, a labyrinth seal 12 is fixedly connected to the inner side of the circumference of the connector 4 , the inner side of the circumference of the labyrinth seal 12 is fixedly connected to the outer surface of the second tube body 2 , and a plurality of partition plates 18 are fixedly connected to the inner cavity of the labyrinth seal 12 at equal intervals.

[0034] By adopting the above technical solution, the labyrinth seal 12 can slow down the leakage rate of water flow when water leaks at the connection between the first tube body 1 and the second tube body 2, reduce water loss, and avoid waste of resources. At the same time, the partition plate 18 can enhance the stability of the labyrinth seal 12, and when water leaks into the labyrinth seal 12, it can avoid the water flow filling the entire labyrinth seal 12, further reducing the waste of water resources.

[0035] Working principle: When the operator needs to fix the first tube body 1 and the second tube body 2, the connecting piece 4 is inserted into the gap between the fixing piece 3 and the first tube body 1, so that the inner wall of the fixing piece 3 contacts one end of the connecting piece 4. At this time, the first tube body 1 and the second tube body 2 are in contact, and the operator rotates the second tube body 2, and the second tube body 2 drives the connecting piece 4 to rotate, and the connecting piece 4 drives the connecting plate 16 and the rotating spring 17 to rotate synchronously. The connecting plate 16 in the inner cavity of the connecting piece 4 is restricted by the inner wall of the fixing piece 3, so that the connecting plate 16 is retracted into the connecting groove 15 and squeezes the rotating spring 17. When the connecting plate 16 corresponds to the clamping groove 9, the connecting plate 16 can be reset and pushed into the clamping groove 9 by the rotating spring 17. At this time, the first tube body 1 and the second tube body 2 are in contact. The two tube bodies 2 are snap-fitted and fixed, and the operator presses the sliding plate 8 to make the sliding plate 8 push the baffle 13 to move, so that the bottom of the baffle 13 no longer extends out of the bottom outside of the fixing device 6, and the baffle 13 squeezes the reset spring 14. The operator puts the bottom of the fixing device 6 into the connecting groove 10 and moves axially along the connecting groove 10 until the bottom of the fixing device 6 contacts the inner cavity of the connecting member 4, then releases the sliding plate 8 to reset the reset spring 14 and push the baffle 13 out. The baffle 13 is snapped into the fixing groove 11 to prevent the fixing member 3 and the connecting member 4 from rotating and deviating, and to avoid unstable connection between the first tube body 1 and the second tube body 2 and leakage. The operator turns the bolt 7 again to set the fixing device 6 tightly against the outer surface of the fixing member 3.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
