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 and 2, the embodiment provides a square faucet elbow spring, which includes an integrally-coiled spring body 100, and the spring body 100 includes, in order in the length direction thereof, a head portion 40, a middle portion 30, and a tail portion 20:

in this embodiment, the head portion 40 and the tail portion 20 are both of a parallel-wound structure, the main body of the middle portion 30 is arc-shaped, and the spring main body 100 is of a progressive spiral transition winding structure in the direction from the head portion 40 and the tail portion 20 to the middle portion, and the progressive spiral transition structure gradually transitions from the head portion to the middle portion to the same distance as the middle portion, so as to realize a smooth transition connection; the cross section of the spring main body is square, so that the function of preventing the inner pipe from being bent and extruded is achieved.

In this embodiment, the head portion 40 is a straight segment, and the tail portion 20 and the main portion of the middle portion 30 are arc-shaped, i.e. the tail portion 20 can be used as an extension arc of the middle portion 30, thereby further avoiding the bending of the head portion of the inner hose.

Meanwhile, the winding density of the head part 40 is higher than that of the tail part 20, and preferably, the head part 40 is of a tight-loop tight winding structure, so that the inner pipe is better protected at the connecting position of the head part 40, and the supporting force is stronger.

The spring main body 100 is formed by integrally winding steel wires into an arc shape, the cross section of the central hole 10 of the spring main body 100 is square, the tail steel rings 22 of the tail part 20 of the spring main body 100 are arranged in parallel, the middle steel rings 32 of the spring middle part 30 are arranged with gaps at equal intervals, and the head steel rings 42 of the spring head part 40 are arranged in parallel.

The steel wires of the spring body 100 in this embodiment are stainless steel. The diameter of the steel wire is 4 mm. The cross section of the spring main body 100 is 24.2mm square, and the number of tail steel coils 22 of the spring tail 20 is smaller than that of head steel coils 42 of the spring head 40. The tail 20 is 15mm in length and the head 40 is 72mm in length.

The gap between the middle steel rings 32 of the spring middle 30 is 15 mm. The spring midsection 30 includes an arcuate section 36 and a linear section 38, the arcuate section 36 being connected to the tail section 20, and the linear section 38 being connected to the head section 40 at a progressively helical pitch. The length of straight section 38 is 178 mm.

In this embodiment, the overall spring height is 230mm, and the distance from the center of the forward-most end of the spring tail 20 to the center of the spring head 40 is 110 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.
