Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 3, the embodiment provides a multi-construction faucet spring tube, which includes an inner supporting spring 200 and an outer compression spring 100 sleeved outside the inner supporting spring.

In this embodiment, the outer compression spring 100 is a straight spring that is integrally wound and tightly wound.

The internal support spring 200 is a curved spring integrally formed by winding, and sequentially includes a head portion 40, a middle portion 30, and a tail portion 20 along a length direction:

wherein, the head portion 40 and the tail portion 20 are tightly wound, and the inner supporting spring 200 is gradually spirally transited to the middle portion 30 from the head portion 40 and the tail portion 20 to the middle portion 30. The head portion 40 and the tail portion 20 are both straight sections, and the middle portion 30 is arc-shaped, so that the reinforced protection of the connecting end of the inner hose and the free flexible protection of the bent end of the inner hose are realized.

Wherein:

the external dense spring 100 is a straight spring formed by winding a steel wire through a CNC spring automatic forming machine to form dense circles and tight circles, the cross section of a central hole 10 of the spring 100 is circular, and two ends of the spring are ground flat.

The internal support spring 200 is divided into a tail portion 20, a middle portion 30 and a head portion 40 along the length direction thereof, the steel rings of the tail portion 20 are closely arranged, the steel rings 32 of the middle portion 30 have a gap therebetween, and the steel rings 42 of the head portion 40 are closely arranged.

The steel wires are all made of stainless steel, and the specific parameters of the two springs are as follows:

the wire diameter of the external dense spring is 2.2mm, and the wire diameter of the internal supporting spring is 3.0 mm; the outer compression spring 100 has an outer diameter of 23.65mm and an overall length of 480 mm.

In the direction from the head portion 40 to the tail portion 20 of the inner supporting spring 200, the outer diameter of the head portion 40 is reduced to support and fix the outer dense spring 100: the head 40 of the inner supporting spring 200 is formed by 4.25 circles of close-packed inner supporting spring with the outer diameter of 22.85mm and 5 circles of close-packed inner supporting spring with the outer diameter of 18.85 mm. The tail part 20 is tightly connected with 1.5 circles, the outer diameter is 18.85, and the head part of the spring is 27mm in close length.

The gap between the middle steel rings 32 of the middle part 30 is 15 mm. The tail part 20 is transited to a tail steel ring 22 by adopting a progressive spiral space, and the space is 15 mm; the tail steel ring 22 is transited to a transition arc shape through an arc-shaped section 36, and the middle part 30 is connected with the head part 40 through an arc-shaped section 38; the head steel ring 42 is connected to the arc section 38 by a gradually changing spiral distance, and the head steel ring 42 and the spring head 40 are close sections. The head part 40 is composed of 5 circles of close bodies with the outer diameter of 18.85mm and 4.25 circles of close bodies with the outer diameter of 22.85mm, and a structure with a wide outer part and a narrow inner part is formed.

The total height of the spring is 295 mm. The distance from the center of the foremost end of the spring tail 20 to the center of the spring head 40 is 245 mm. The span length of the central circular arc 38 of the foremost end of the spring tail 20 is 220 mm.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
