Abstract

The utility model discloses a folding pipe fitting. A pipe fitting is mainly provided with a main pipe segment and an auxiliary pipe segment, wherein, a section head which can penetrate and extend with a smaller diameter is arranged at a butting end of the auxiliary pipe segment and the main pipe segment. The upper segment and the lower segment of the section head to be positioned and hidden in the pipe of the main pipe segment in the mode that a groove is clamped by a steel ball. Then, the utility model has the advantage of beautiful appearance. A fixed bolt is tightly bundled by a fast spanner of a pipe bundle. The fast spanner is led to be butted in a chute of the upper segment of the main pipe segment after the fast spanner passes through a through hole which is arranged on the pipe wall of the main pipe segment. Compared with a common article, the strength of a combined segment is stronger. The segmental design of the pipe fitting is favorable for folding, collecting and butting. The utility model has the advantages of space saving and portability.

Description

A kind of Foldable pipe fittings

The utility model relates to a kind of Foldable pipe fittings.

Volume is excessive in use in the design of existing many products, not only is not easy to carry, and also takes up space during collection, so collapsible structure just is used on this series products in a large number, folds the effect that the back reduces volume to reach; Many again collapsible products, its basic framework be with tubular armature as supporter, the extension form of this tubular armature is the main body that quite takes up space, therefore, folding structure is located in this tubular armature mostly; Common is example with the Regular Bicycle; promptly many long, high skeleton places that are connected on vehicle frame that establish by the pivot joint joint; make it fold that the back is shortened or and lean on; be convenient to collect or carry; yet known body framing is merely its pipe fitting to be changed into articulating two sections that fold mutually, this structure regular meeting see fold (pivot joint) locate exposed outside, not only be short of aesthetic property; the intensity at this place is also relatively poor, also can increase psychological sense of insecurity to the user.

The purpose of this utility model promptly will provide a kind of Foldable pipe fittings, utilize the segmentation Dary bending of its pipe fitting to receive the effect of leaning on, and it upright straight can be hidden in joint structure in the pipe fitting after affixed in use, and cooperates a tube bank fix, promptly increases its anchoring strength and is convenient to again operate and carry.

For reaching above-mentioned purpose, what solution of the present utility model adopted is a kind of Foldable pipe fittings, and it mainly is that pipe fitting is made as major and minor pipeline section, wherein:

The main leg establishes a profile groove on axially articulating the tube wall fold end with looped pipeline section corresponding, and the tube bank of noose one band speed wrench, places a gim peg on the ring body of this tube bank, establishes a through hole on main leg's tube wall, and gim peg protrudes out in pipe after passing this through hole;

The looped pipeline section is to establish one than the path and the section header that can stretch through with place, main leg's butt end, and this section header is made of epimere and hypomere pivot joint, and its sidepiece of upper and lower section is respectively established a coaxial chute.

In addition, wearing the knot pivot with a rivet again after the epimere of above-mentioned section header and hypomere can borrow flange and pivot seat to plug connects, and epimere or hypomere one relatively the inner trip is set, another relatively the inner then correspondence be provided with groove, its trip can and hold by a spring contact one steel ball and form in a volumetric cylinder.

Owing to adopt said structure, the utility model in the specific implementation, upper and lower section of its looped pipeline section section header engages groove by steel ball and locatees and be hidden in main leg's the pipe, has aesthetic property, utilizing the speed wrench of restraining to tighten gim peg again supports only in the chute of epimere it, it is strong that the intensity of its adapter section is commonly used product again, and the segment design of pipe fitting then helps bending and receives and be easy to carry again by promptly saving the space.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Fig. 2 is an assembled sectional view of the present utility model;

Fig. 3 cooperates the enforcement scheme drawing of seat cushion for the utility model;

Fig. 4 cooperates the enforcement scheme drawing of handgrip for the utility model;

Fig. 5 is the diagram of work one that folds of the present utility model;

Fig. 6 is the diagram of work two that folds of the present utility model;

At first see also shown in Fig. 1,2, the utility model mainly is that pipe fitting is made as major and

minor pipeline section

1,2, wherein:

Main leg 1 establishes a profile groove 11 at the corresponding tube wall that folds end that articulates with looped pipeline section 2 on axially, and the tube bank 3 of pipe end noose one band speed wrench 31, the spiral shell knot places a gim peg 32 on the ring body of this tube bank 3, and establish a through hole 12 at main leg 1 tube wall, gim peg 32 can pass this through hole 12 and protrude out in pipe;

Looped pipeline section 2 is to establish one than the path and the section header 4 that can stretch through with main leg 1 butt end, section header 4 is articulated with hypomere 42 by epimere 41 and constitutes, on it,

hypomere

41,42 respectively borrow its flange 411 to plant mutually with pivot seat 421, and even with a rivet 43 cross-under pivots, and on,

hypomere

41,42 sidepiece respectively establish one can be involutory on coaxial chute 412,422, not only can for pass tube bank 3 and the gim peg 32 of main leg's 1 tube wall stretch to, its part is all stretched put and in main leg 1, be fastened the location, the inner relatively appearance hole 423 that forms of the epimere 41 of section header 4 or hypomere 42, and be provided with a trip 44 in this appearance hole 423, this trip 44 is by spring 441 contacts, one steel ball 442 and be contained in a volumetric cylinder 443 interior formation, and the flange 411 of epimere 41 is provided with groove 413 at steel ball 442 places of corresponding trip 44.

By above-mentioned design as can be known, when the structure of its major and

minor pipeline section

1,2 was used in the seat cushion structure of Regular Bicycle, as shown in Figure 3, this main leg 1 was a seat cushion

vertical tube

5, and 2 of looped pipeline sections are the interspersed pipe 6 of seat cushion bottom, the seat cushion bendable is folded lean against on the vehicle frame; Or as shown in Figure 4, also can this major and

minor pipeline section

1,2 structures be set in the stage casing of the longer handgrip 7 of Kickboard Scooter, make handgrip 7 bent folding; And for example shown in Figure 2, in the specific implementation, the epimere 41 of section header 4 utilizes the steel ball 442 of trip 44 to engage groove 413 location with hypomere 42 vertical directions and is pressed in main leg 1 interior the hiding of pipe, and restrain 3 gim peg 32 embedding cunnings and support in the chute 412 of epimere 41 that to end group solid, tighten with the speed wrench 31 of tube bank 3 again, combined structure is promptly latent to be put in main leg 1, and the intensity ratio of its adapter section is commonly used the intensity of product and wanted high.

When desiring to fold, can draw back speed wrench 31 earlier makes tube bank 3 no longer tightly restraint main leg 1 and loosens the section header 4 of looped pipeline section 2, shown in Fig. 5,6, these looped pipeline section 2 pulling section headers 4 make the part of epimere 41 expose main leg 1 upper end, make the interspersed pipe of seat cushion bottom or the looped pipeline section 2 of handgrip hypomere be easy to fold, and reduced volume and be easy to carry.
