Problems solved by technology

[0002] Now there are many heaters connected by iron pipes that have been used for a long time and need to be replaced with PVC plastic pipes for connection. However, the space of these houses is relatively small. Due to the limited indoor space, it is very inconvenient to replace, especially in the corner of the wall. Once there is a leak in the PVC plastic pipe connected by hot melt, because the space is very small, it is inconvenient for people to enter, and the maintenance cannot be completed basically, and the use effect is very unsatisfactory.

Embodiment 1

[0025] A heating and ventilation pipe plastic natural bending support and a fixing device for heating and ventilation pipes. Shaped support plate 2, top arc support plate 3, described top arc support plate is welded positive thread rod 4, described bottom arc support plate is welded reverse thread rod 5, described positive thread rod and described The anti-threaded rods are connected by positive and negative threaded sleeves 6. The positive and negative threaded sleeves are provided with an upper card slot 7 and a lower card slot 8. The upper card slot is set opposite to the lower card slot. The upper card slot is bonded with the upper magnetic sheet 9, the lower card slot is bonded with the lower magnetic sheet 10, and the U-shaped iron frame 11 is inserted and connected between the upper card slot and the lower card slot. One side of the opening end of the U-shaped iron frame snaps into the upper card slot to attract the upper magnetic piece to fix it, and it can be fixed wi...

Embodiment 2

[0028] In the HVAC pipeline plastic natural bending support and HVAC pipe fixing device described in Example 1, a through hole 12 is opened at the closed end of the U-shaped iron frame, and a round rod 13 is inserted into the through hole. The end of the rod is fixedly connected to the fixed plate 14, and the fixed plate is attached to the through hole and fixed by bonding. The round rod has a threaded section 15, and the threaded section is connected to the baffle plate 16. The baffle is provided with a threaded hole, and the threaded hole is connected to the threaded section to adjust the position.

[0029] The round rod can smoothly send the baffle plate and the combined support into the PVC plastic pipe, providing the necessary guarantee for the bending of the PVC plastic pipe, ensuring that the quality of the PVC plastic pipe is good when the pipe is bent at the bend, and the quality of the pipe after bending is good. The use effect of PVC plastic pipe is good.

Embodiment 3

[0031] In the HVAC pipeline plastic natural bending support and HVAC pipe fixing device described in Example 1, the combined support is used in conjunction with the counter baffle 17, the counter baffle is welded with the internal thread pipe 18, and the internal thread The pipe is connected with an externally threaded rod 19 , the externally threaded rod is connected with an external support rod 20 , and the external support rod is connected with a bracelet 21 .

[0032] The baffle plate can block the sand in the bending part of the PVC plastic pipe, so as to ensure less deformation of the PVC plastic pipe during bending, and ensure good use effect of the PVC plastic pipe after bending.

[0033] The length between the internally threaded pipe and the externally threaded rod can be adjusted, and the length of the internally threaded pipe and the externally threaded rod can also be shortened, which can fully meet the requirements of use.

Abstract

The invention discloses a heating and ventilation pipeline plastic natural bending supporting and heating and ventilation pipe fixing device and an operation method. The device comprises a PVC plasticpipe, wherein a combined supporting part is arranged at the position, needing to be bent, of the PVC plastic pipe; the combined supporting part comprises a bottom arc-shaped supporting plate and an arc-shaped supporting plate; the top arc-shaped supporting plate is welded with a positive threaded rod, and the bottom arc-shaped supporting plate is welded with a reverse threaded rod; the positive threaded rod and the reverse threaded rod are connected through a forward and reverse threaded sleeve; an upper clamping groove and a lower clamping groove are oppositely arranged; the upper clamping groove is adhered to an upper magnetic sheet; the lower clamping groove is adhered to a lower magnetic sheet; a U-shaped iron frame is clamped between the upper clamping groove and the lower clamping groove; one side of the opening end of the U-shaped iron frame is clamped into the upper clamping groove to attract and fix the upper magnetic sheet; and the other side of the opening end of the U-shaped iron frame is clamped into the lower clamping groove to attract and fix the lower magnetic sheet. The device is used for a heating and ventilation pipeline.

Description

Technical field: [0001] The invention relates to a plastic natural bending support for a heating and ventilation pipe, a fixing device for the heating and ventilation pipe and an operation method. Background technique: [0002] Now there are many heaters connected by iron pipes that have been used for a long time and need to be replaced with PVC plastic pipes for connection. However, the space of these houses is relatively small. Due to the limited indoor space, it is very inconvenient to replace, especially in the corner of the wall. Once there is a leak in the PVC plastic pipe connected by hot melt, because the space is very small, it is inconvenient for people to enter, and the maintenance cannot be completed basically, and the use effect is very unsatisfactory. Invention content: [0003] The purpose of the present invention is to provide a natural bending PVC plastic pipe to ensure that there will be no water leakage points, and to use a safe natural bending support f...
