Abstract
The utility model relates to a kind of Telescopic flexible pipe.A kind of Telescopic flexible pipe, is saved by multiple tube unit and connects to form continuously, successively; Each tube unit joint comprises tubulose our department and one can the bending rebate of elasticity bending; Tubulose our department one end external diameter is greater than the other end, and the outside of its other end is provided with the annular protrusion of radially outward protrusion, is embedded with an annular permanent magnet in annular protrusion; Can one end of bending rebate of elasticity bending and the other end of tubulose our department be connected as a single entity; Can the other end of bending rebate of elasticity bending and one end of adjacent next tubulose our department be connected as a single entity; The middle part of bending rebate of elasticity bending can be provided with a steel loop attracting with annular permanent magnet; When the bending of bending rebate, the position of steel loop is corresponding with annular permanent magnet position also can be attracted mutually.The advantage of this Telescopic flexible pipe is: the Telescopic flexible pipe that automatically can extend with hydraulic pressure increasing, applied range, serviceability is good.
Description
Technical field
The utility model belongs to flexible pipe field, particularly relates to a kind of Telescopic flexible pipe.
Background technique
It is all that tube body itself makes fold or multistage folded state realizes that flexible pipe of the prior art stretches, and the corrugations that namely tube wall of its Telescopic flexible pipe is generally coiled by the length direction around described Telescopic flexible pipe is formed.Such Telescopic flexible pipe its when body is stretched or in body, hydraulic pressure is larger, flexible pipe can automatically extend, but the flexible pipe after extending wants manual compression to go back, and therefore causes existing this flexible pipe application area extensively, cannot use in a lot of field.In addition, existing Telescopic flexible pipe is all very thin at bending part, and body itself does not have elasticity, and flexible number of times is very limited.
Summary of the invention
The Telescopic flexible pipe that goal of the invention of the present utility model is to provide a kind of can increasing with hydraulic pressure and automatically extends, this Telescopic flexible pipe applied range, serviceability is good.
In order to realize foregoing invention object, the utility model have employed following technological scheme:
A kind of Telescopic flexible pipe, is saved by multiple tube unit and connects to form continuously, successively; Each described tube unit joint comprises tubulose our department and one can the bending rebate of elasticity bending; Described tubulose our department one end external diameter is greater than the other end, and the outside of its other end is provided with the annular protrusion of radially outward protrusion, is embedded with an annular permanent magnet in described annular protrusion; Describedly can one end of bending rebate of elasticity bending and the other end of described tubulose our department to be connected as a single entity; Describedly can the other end of bending rebate of elasticity bending and one end of the described tubulose our department of the adjacent next one to be connected as a single entity; Describedly the middle part of bending rebate of elasticity bending can be provided with a steel loop attracting with annular permanent magnet; When the bending of bending rebate, the position of described steel loop is corresponding with described annular permanent magnet position also can be attracted mutually.
As preferably, described tubulose our department is made up of rubber material, and described bending rebate is made up of silica gel material.
Have employed the Telescopic flexible pipe of technique scheme, this flexible pipe is provided with the annular protrusion of embedded annular permanent magnet by tubulose our department one end, again by being provided with a steel loop attracting with annular permanent magnet in the middle part of bending rebate, when the bending of bending rebate, due to the attraction force of magnet, make bending rebate be in bending state always.Until hydraulic pressure is greater than a threshold value, overcomes the attraction force between steel loop and annular permanent magnet and impel bending rebate elasticity to stretch.Therefore, this Telescopic flexible pipe is compared with existing flexible pipe, and it can strengthen with hydraulic pressure and automatically extend, stretch because it relies on permanent magnet nature to maintain self, need not make fold shape by flexible pipe self, therefore its resistance to compression, flexible number of times and serviceability are fine, are with a wide range of applications.
Accompanying drawing explanation
Fig. 1: the cross-sectional view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: a kind of Telescopic flexible pipe as shown in Figure 1, this Telescopic flexible pipe is saved by multiple tube unit and connects to form continuously, successively.Wherein, each described tube unit joint comprise tubulose our department 1 and one can the bending rebate 3 of elasticity bending.Tubulose our department 1 is made up of rubber material, and bending rebate 3 is made up of silica gel material.
See as shown in Figure 1, above described tubular our department one end 1a external diameter is greater than the other end 1b, and the outside of its other end 1b is provided with the annular protrusion 2 that radially outward protrudes, and is embedded with an annular permanent magnet 21 in annular protrusion 2.Above-mentionedly can one end of bending rebate 3 of elasticity bending and the other end 1b of tubulose our department 1 to be connected as a single entity; Can the other end of bending rebate 3 of elasticity bending and one end 1a of the described tubulose our department 1 of the adjacent next one be connected as a single entity.The middle part of bending rebate 3 of elasticity bending can be provided with a steel loop 31 attracting with annular permanent magnet 21.When 3 bending of bending rebate, the position of steel loop 31 is corresponding with annular permanent magnet 21 position also can be attracted mutually.
Above-mentioned annular protrusion 2 is side cross sections is similar leg-of-mutton protuberance, and wherein annular protrusion 2 is annular burnishing surfaces near a side of bending rebate 3, and the one side away from bending rebate 3 is an annular slope.Above-mentioned bending rebate 3 side cross section is inverted S-shaped, a bending part position in the middle part of bending rebate 3 is fixed with above-mentioned steel loop 31, when 3 bending of bending rebate, steel loop 31 is attracted by annular permanent magnet 21, and bending rebate 3 bending part is just against by this steel loop 31 on the annular burnishing surface of above-mentioned annular protrusion 2.
During use, when Telescopic flexible pipe intraluminal fluid pressure sharply increases, more than a threshold value, tube unit on this flexible pipe joint will to save land elongations by a joint one, often extends a joint, will increase the pressure that pipe inner volume sharply increases with balance.
In the utility model, the material of above described tubular our department 1 and bending rebate 3 not chooses at random, its rubber selecting tubulose our department 1 to select price inexpensively durable again, and bending rebate 3 adopts silica gel, why like this, be because the bending rebate 3 that silica gel is made can be connected as a single entity with rubber in the fabrication process, and the bending rebate 3 that silica gel is made is after repeatedly folding, elasticity, antifatigue, serviceability are all very good.
