Description

Flexible pressure-resistant polytetrafluoroethylene corrugated pipe

Technical Field

The utility model particularly relates to a flexible withstand voltage polytetrafluoroethylene bellows.

Background

The flexible corrugated pipe is a ventilating, exhausting and draining element with wide application, and is an essential important part for bath heaters, ventilators, water tanks, washing machines, range hoods and the like. The flexible corrugated pipe has the important characteristics of being capable of extending, contracting and bending under the action of external force so as to meet various requirements. For example, air conditioners, refrigerators and the like, bellows are often used to connect the compressor to the circulation line.

However, the existing flexible plastic corrugated pipe cannot be shaped by itself after being stretched or bent due to the elasticity, so that the existing flexible plastic corrugated pipe has the disadvantages of low structural strength, poor pressure resistance and the like, and is easy to break or crack during extrusion or twisting.

Disclosure of Invention

In view of this, the present invention provides a polytetrafluoroethylene corrugated pipe with high structural strength, good pressure resistance, and less breakage and cracking during extrusion or twisting.

In order to solve the technical problem, the technical scheme of the utility model is that:

a flexible pressure-resistant polytetrafluoroethylene corrugated pipe comprises a corrugated pipe body and corrugated pipe joints which are positioned at two ends of the corrugated pipe body and are integrally formed with the corrugated pipe body; the corrugated pipe body includes the bellied ripple end of surface, reinforcing corrugated pipe body compressive capacity to and the smooth and flat pipe wall of internal surface, inside reinforcing corrugated pipe body structural strength's that still is provided with of corrugated pipe body, and with corrugated pipe body integrated into one piece's buffering support, the buffering support is including the inner chamber pipe that is used for carrying the material to and one end and inner chamber pipe integrated into one piece, the other end and corrugated pipe body integrated into one piece's support bar, the support bar is provided with more than one, and distributes around inner chamber pipe annular array.

Preferably, an isolation cavity is further arranged between the supporting bars.

Preferably, the two side faces of the supporting bar are arranged in an arc shape, and the middle part of the supporting bar is inwards sunken.

Preferably, the corrugated end is arranged in a semicircular shape.

Preferably, the pipe wall is arranged in an inward concave mode.

The utility model discloses technical effect mainly embodies in following aspect: through being provided with the buffering support that is used for buffering the extrusion force in the bellows body, under the flexibility that does not influence the polytetrafluoroethylene bellows, carry the material through inner chamber pipe, a bearing structure is constituteed at the bellows body to the cooperation support bar, receive to twist reverse or can resume the original state rapidly according to elasticity after the extrusion when using, in addition, can also strengthen the structural strength of the bellows body through the buffering support, effectively prevent the bellows body because of the extrusion or twist reverse the condition that appears the rupture and burst.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

Examples

A flexible pressure-resistant polytetrafluoroethylene corrugated pipe is shown in figures 1-3 and comprises a corrugated pipe body 1 and corrugated pipe joints 2 which are positioned at two ends of the corrugated pipe body 1 and are integrally formed with the corrugated pipe body 1; the corrugated pipe body 1 comprises a corrugated end 11 with a convex outer surface and used for enhancing the pressure resistance of the corrugated pipe body 1, and a pipe wall 12 with a smooth and flat inner surface, wherein the corrugated end 11 is arranged in a semicircular shape. The pipe wall 12 is arranged in a concave manner, so that the buffer space of the isolation cavity 33 is increased, the pressure resistance and elasticity of the corrugated pipe body 1 are enhanced, and the corrugated pipe body 1 can be recovered through the elasticity existing in the corrugated pipe body 1 after being extruded.

Inside 1 structural strength's of reinforcing bellows body, and with 1 integrated into one piece's of bellows body buffering support 3 of bellows body still being provided with of bellows body, buffering support 3 is including the inner chamber pipe 31 that is used for carrying the material to and one end and inner chamber pipe 31 integrated into one piece, the other end and the support bar 32 of 1 integrated into one piece of bellows body, support bar 32 is provided with more than one, and distributes around inner chamber pipe 31 annular array for buffering support 3 reinforcing bellows body 1's structural strength. Still be provided with between support bar 32 and the support bar 32 and keep apart chamber 33, keep apart the extrusion force that the chamber is used for buffering corrugated pipe body 1 to receive to do not influence the interior chamber pipe 31 material transport condition. The both sides face of support bar 32 sets up for the arc, and the middle part is inside sunken, can increase the buffer space who keeps apart chamber 33 to effectively protect inner chamber pipe 31.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
