Abstract
The utility model discloses a kind of retractable curved exhaust duct, includes the spring of tube wall and fitting tube wall arrangement, and spring is divided into several sections, and each adjacent springs section can be kept completely separate；Each adjacent springs section can also connect, and gap is blocked on the spring body of separated place, can block unit as spring using a unit spiral, half unit spiral or a quarter unit spiral.Above structure can be axially retractable in reservation Universal pipe and bends indeformable feature simultaneously, handles spring structure, convenient for users to blocking tube body as needed, further facilitates user's use.
Description
Technical field
The utility model is related to a kind of pipe, a kind of particularly retractable curved exhaust duct conveniently blocked.
Background technology
Universal pipe is plumbing installation common in industrial practice and practical experience of life, generally includes support spring structure as branch
Support, and arrange tube wall along spring structure, the retractable curved exhaust duct of such structure can be flexible along axle of spring, is easy to use
And transport, and spring can prop up internal structure, and pipeline may be implemented and bent to all directions, and will not be sent out in bending place
The raw undesirable deformation for influencing using effect.But since the characteristics of production practices, makes the ruler of retractable curved exhaust duct product
Very little incomplete adaptation usage scenario, user usually require to carry out truncation to Universal pipe.The Universal pipe of the prior art it is interior
Portion's spring is typically the spring structure of one, when blocking pipeline and inconvenient.
Utility model content
Universal pipe in order to solve the prior art is not easy the defect blocked, and the utility model provides a kind of retractable curved row
Air hose handles spring structure, and use is conveniently blocked while the advantages of retaining spring structure.
Technical solution adopted by the utility model to solve its technical problems is：A kind of retractable curved exhaust duct, including
The spring of tube wall and fitting tube wall arrangement.
Spring is divided into several sections, and each adjacent springs section can be kept completely separate；Each adjacent springs section can also connect, and divide
Every blocking gap on the spring body at place.
Preferably, it (can be passed through for 360 degree around axle of spring spiral with certain point on spring body with a unit spiral
The spring body crossed is a unit spiral) it is to block unit.
Preferably, can be to block unit with half unit spiral.
Preferably, can be to block unit with a quarter unit spiral.
The material of tube wall can select heat-resisting material, acidproof base material, resistant material according to different use environments
Or antistatic material is made.
The utility model has the beneficial effects that retain Universal pipe can the axially retractable and indeformable feature of bending it is same
When, spring structure is handled, convenient for users to blocking tube body as needed, further facilitates user's use.
Description of the drawings
The utility model is further described below in conjunction with attached drawing.
Fig. 1 is the overall schematic of the utility model；
Fig. 2 is spring one embodiment structure chart；
Fig. 3 is another example structure figure of spring.
In figure, 1. tube walls, 2. springs, 3. block gap.
Specific implementation mode
【Embodiment 1】
A kind of retractable curved exhaust duct includes the spring 2 of tube wall 1 and the fitting arrangement of tube wall 1, and it is several sections that spring 2, which divides,
Each adjacent springs section is kept completely separate (as shown in Figure 3).It is a unit spiral, half unit spiral that spring, which blocks unit,
Or a quarter unit spiral.The making material of tube wall can be heat-resisting material, acid resisting material, alkali resistant materials, corrosion-resistant
Material or antistatic material.
【Embodiment 2】
Each adjacent springs section connection, and gap 3 (as shown in Figure 2) is blocked on 2 body of the spring of separated place.Spring blocks
Unit is a unit spiral, half unit spiral or a quarter unit spiral.The making material of tube wall can be with
For heat-resisting material, acid resisting material, alkali resistant materials, resistant material or antistatic material.
Above-described embodiment is the more excellent way of realization of the utility model, to illustrate the basic structure and base of the utility model
This thought, should not be construed as the absolute limitation to the utility model, and one of ordinary skill in the art is not departing from this
Under the premise of the basic structure and basic thought of utility model, the implementation of the utility model is taken not absolute with above-described embodiment
Identical treatment measures should also be considered as in the rights protection scope of the utility model.
