Specific embodiment

The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of flexible water pipe and joint design, including：Bellows 100, Front body 200, rear body 300 and spiral cover 250, irrigate for flowers and trees and the field such as carwash, wherein, rear body 300 and spray Rifle or water gun connection, the front end of front body 200 is connected with bellows 100, and the rear end of front body 200 can also It is connected with spray gun or water gun.

The bellows 100 include the elastic outer lining 120 of the inner tube 110 that freely can be stretched and tubulose, described Inner tube 110 is located in the elastic outer lining 120 and both are fixedly connected, and bellows 100 have undulatory fold, can be certainly By stretching.

, on the outer surface of inner tube 110, so as to form the profile of tubulose, and elasticity is outer for 120 uniform fold of elastic outer lining The inner surface of lining 120 is fixed together with the outer surface of inner tube 110, and when inner tube 110 is opened, elastic outer lining 120 can therewith Elongation, while producing elastic force, and still closely binds on the outer surface of the inner tube 110 for having extended, when external force disappears, Inner tube 110 again can in the presence of elastic outer lining 120 retraction original state.

When the water with certain hydraulic pressure is flowed in bellows 100, bellows 100 are automatic according to hydraulic pressure size Elongation, the stroke of bellows 100 are usually 1：3 or 1:3.5, if exceeding the magnification, then bellows 100 It is easily damaged.

200 front end of front body is provided with front port 210, and the external diameter of front port 210 is identical with the internal diameter of inner tube 110, described External screw thread layer 220 is provided with outside front body 200, the end of the external screw thread layer 220 is provided with a ring around the front port 210 claw 230, is formed with annular gap 240, the bellows between the claw 230 and the front port 210 100 are located in the annular gap 240 and are connected with the front port 210.

In simple terms, it is exactly that external screw thread layer 220 is arranged concentrically with front port 210, and connects on the front end of external screw thread layer 220 There is claw 230, when bellows 100 are located in the front end of front body 200, front port 210 is plugged in inner tube 110, block Pawl 230 is clipped on elastic outer lining 120, so as to bellows 100 are fixed on front body 200.

The spiral cover 250 is threaded on the external screw thread layer 220, in order to the claw 230 is pressed in the ripple On telescoping tube 100.

The front end of the rear body 300 is threaded on the front body 200 by the external screw thread layer 220, and front Body 200 is connected with rear body 300；The rear end of body 300 could be arranged to another kind of attachment structure or bore afterwards, for example, live Dynamic set 310 and the snap fit of buckle, so that be adapted to the spray gun of another kind of specification.

As flexible water pipe much regional or national at present is had differences with the specification of joint design, the such as U.S. Joint and spray gun be typically with the form being threadedly coupled, and Europe is typically with the mode of buckle clamping, the company of spray gun Socket part can be located in the rear end of joint, and be snapped and block.

So when actually used, when running into situation for example made in U.S.A, can first by 300 the past of rear body body 200 Separate, the external screw thread layer 220 of front body 200 is directed at the internal thread on spray gun connecting portion then, both is threadedly coupled, is run into For example during the situation in Europe, then directly the connecting portion of spray gun directly can be plugged in rear body 300, can in rear body 300 To be preferably provided with buckle, so that both are reliably connected.

Water pipe when using can automatic telescopic, and convenient and practical, joint design goes for multiple types specification.

As Figure 1 and Figure 4, on the basis of above-mentioned embodiment, the rear end of the rear body 300 is arranged with reset bullet Spring (being not drawn in figure) and the movable sleeve 310 that can be slided on body 300 in the rear, are embedded with buckle on the rear body 300 (being not drawn in figure), the movable sleeve 310 are squeezed on the buckle, and described back-moving spring one end is supported with the movable sleeve 310 Touch the connection other end and contradict with the rear body 300 and be connected.

In simple terms, exactly installing hole is offered in the rear end of rear body 300, be provided with buckle in the installing hole, spray When the connecting portion of rifle is located in rear body 300, movable sleeve 310 extrudes buckle, so as to block the connecting portion of spray gun.

Back-moving spring is socketed on rear body 300, herein it is worthy of note that, back-moving spring is limited in rear body 300 Fixed position on, for for movable sleeve 310 provide reset elastic force.

Crushing block corresponding with buckle can be preferably provided with the inwall of movable sleeve 310, and movable sleeve 310 is by extruding Block is contradicted on buckle, and buckle is pressed to the inside of rear body 300, herein it is worthy of note that, only when crushing block is extruded During on buckle, buckle just can be locked to the connecting portion of spray gun, when movable sleeve 310 slides into other positions, crushing block Separate with buckle, buckle releases locking state, so that the connecting portion of spray gun is separated with the rear end of rear body 300.

As shown in Figure 1, Figure 2, Figure 3 shows, on the basis of above-mentioned embodiment, the end of the spiral cover 250 has opening, institute Spiral cover 250 is stated on external screw thread layer 220 during precession, the inner edge of the opening extrudes the claw 230, so that claw 230 blocks Firmly bellows 100.

As shown in Figure 1, Figure 3, on the basis of above-mentioned embodiment, restraining position ring block is set on the external screw thread layer 220 260, spacing ring 260 is located at the middle part of front body 200, and when the connecting portion of spray gun is internal thread, connecting portion can be screwed into outer spiral shell In lamina 220, the termination for being screwed to connecting portion is contradicted on spacing ring 260, so as to play spacing effect, it is to avoid the connection of spray gun Portion's excess of stroke in connection.

Preferably, the claw 230 is strip, and the claw 230 is arranged towards the one side of the annular gap 240 There are some double wedges 231 in order to strengthen 230 grip of the claw.

As Figure 1 and Figure 4, on the basis of above-mentioned embodiment, the leading section of the rear body 300 be provided with order to Increase the straight-line knulring portion 320 of frictional force, so can conveniently turn rear body 300, it is to avoid produce when turning rear body 300 and beat Sliding.

As shown in figure 1, on the basis of above-mentioned embodiment, said inner tube 110 is with folding wrinkle and telescopic Tubular structure.

As shown in Figure 1, shown in Figure 5, on the basis of above-mentioned embodiment, said inner tube 110 is made up of polypropylene, and polypropylene is just It is PP materials, elastic outer lining 120 is made up of thermoplastic polyester elastomer, and thermoplastic polyester elastomer is exactly TPEE materials, above-mentioned The bellows 100 that bi-material is made, can improve the number of times of stretching, with the difference of the proportioning of bi-material, stretch Number of times can obtain huge lifting, in simple terms, can exactly make bellows 100 more durable, when stretching is opened not Easily burst apart.

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model institute Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
