Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in figure 1, figure 2, figure 3, figure 4 and figure 5, a kind of flexible water pipe and joint structure, comprising: bellows 100,
Preceding tube body 200, rear tube body 300 and spiral cover 250, for fields such as flowers and trees irrigation and carwash, wherein rear tube body 300 and spray
Rifle or water gun connection, the front end of preceding tube body 200 connect with bellows 100, and the rear end of preceding tube body 200 can also be with
It is connect with spray gun or water gun.
The bellows 100 include the elastic outer lining 120 of the inner tube 110 and tubulose that can freely stretch, described
Inner tube 110 is located in the elastic outer lining 120 and the two is fixedly connected, and bellows 100 have undulatory fold, can be certainly
By stretching.
Elastic 120 uniform fold of outer lining is on the outer surface of inner tube 110, to form the shape of tubulose, and elasticity is outer
The inner surface of lining 120 and the outer surface of inner tube 110 are fixed together, and when inner tube 110 is opened, elastic outer lining 120 can therewith
Elongation, while generating elastic force, and still closely bonding is on the outer surface of the inner tube 110 extended, when external force disappears,
Inner tube 110 can retract original state under the action of elastic outer lining 120 again.
When flowing into the water with certain hydraulic pressure in bellows 100, bellows 100 are automatic according to water pressure
Elongation, the stroke of bellows 100 is usually 1:3 or 1:3.5, if being more than the magnification, then bellows 100
It is easily damaged.
Preceding 200 front end of tube body is provided with front port 210, and the outer diameter of front port 210 is identical as the internal diameter of inner tube 110, described
It is provided with external screw thread layer 220 outside preceding tube 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 threaded through in the annular gap 240 and are connected to the front port 210.
It in simple terms, is exactly that external screw thread layer 220 is arranged concentrically with front port 210, and is connected on the front end of external screw thread layer 220
There is claw 230, before bellows 100 are threaded through when the front end of tube body 200, front port 210 is plugged in inner tube 110, card
Pawl 230 is clipped on elastic outer lining 120, thus before bellows 100 are fixed on tube body 200.
The spiral cover 250 is threaded on the external screw thread layer 220, the claw 230 is pressed in the ripple
On telescoping tube 100.
The front end of tube body 300 is threaded on the preceding tube body 200 by the external screw thread layer 220 after described, and preceding
Tube body 200 is connected to rear tube body 300；The rear end of tube body 300 can be set to another connection structure or bore afterwards, such as living
The snap fit of dynamic set 310 and buckle, to be adapted to the spray gun of another specification.
Since many areas or the flexible water pipe of country and the specification of joint structure have differences at present, such as the U.S.
Connector and spray gun be usually using the form being threadedly coupled, and Europe is usually the company of spray gun using by the way of buckling and being clamped
Socket part can be threaded through the rear end of connector, and be snapped and block.
So in actual use, it, can be first by rear tube body 300 from preceding tube body 200 when encountering situation for example made in U.S.A
Then the external screw thread layer 220 of preceding tube body 200 is directed at the internal screw thread on spray gun interconnecting piece, the two is threadedly coupled, is encountered by separation
Such as when the case where Europe, then directly the interconnecting piece of spray gun directly can be plugged in rear tube body 300, it can in rear tube body 300
To be preferably provided with buckle, so that the two be made to be reliably connected.
Water pipe when using can automatic telescopic, and convenient and practical, joint structure can be adapted for multiple types specification.
As Figure 1 and Figure 4, on the basis of the above embodiment, the rear end cap of the rear tube body 300, which is equipped with, resets bullet
Spring (being not drawn into figure) and the movable sleeve 310 that can be slided on tube body 300 after described, it is described after on tube body 300 embedded with buckle
(being not drawn into figure), the movable sleeve 310 are extruded on the buckle, and described reset spring one end is supported with the movable sleeve 310
The touching connection other end and the rear tube body 300 are contradicted and are connected.
In simple terms, mounting hole exactly is offered in the rear end of rear tube body 300, buckle is provided in the mounting hole, sprayed
When the interconnecting piece of rifle is threaded through in rear tube body 300, movable sleeve 310 squeezes buckle, to block the interconnecting piece of spray gun.
Reset spring is socketed on rear tube body 300, it is worth noting that, reset spring is limited in rear tube body 300 herein
Fixation position on, for providing the elastic force of reset for movable sleeve 310.
Crushing block corresponding with buckling can be preferably provided on the inner wall of movable sleeve 310, movable sleeve 310 passes through extruding
Block contradicts on buckle, and buckle is pressed to the inside of rear tube body 300, herein it is worth noting that, only when crushing block squeezes
When on to buckle, buckle can just be locked the interconnecting piece of spray gun, when movable sleeve 310 slides into other positions, crushing block
It is separated with buckle, buckle releases locking state, so that the interconnecting piece of spray gun and the rear end of rear tube body 300 be made to separate.
As shown in Figure 1, Figure 2, Figure 3 shows, on the basis of the above embodiment, the end of the spiral cover 250 has opening, institute
Spiral cover 250 is stated in precession on external screw thread layer 220, the inner edge of the opening squeezes the claw 230, so that claw 230 be made to block
Firmly bellows 100.
As shown in Figure 1, Figure 3, on the basis of the above embodiment, restraining position ring block is set on the external screw thread layer 220
260, stop collar 260 is located at the middle part of preceding tube body 200, and when the interconnecting piece of spray gun is internal screw thread, interconnecting piece can be screwed into outer spiral shell
In lamina 220, the end for being screwed to interconnecting piece is contradicted on stop collar 260, to play the role of limit, avoids the connection of spray gun
Portion's excess of stroke in connection.
Preferably, the claw 230 is strip, and the one side of the claw 230 towards the annular gap 240 is arranged
There are several double wedges 231 to enhance 230 grip of claw.
As Figure 1 and Figure 4, on the basis of the above embodiment, after described the front end of tube body 300 be provided with to
The straight-line knulring portion 320 for increasing frictional force, can be convenient turn rear tube body 300 in this way, generates and beats when avoiding turning rear tube body 300
It is sliding.
As shown in Figure 1, on the basis of the above 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 the above embodiment, said inner tube 110 is made up of polypropylene, and polypropylene is just
It is PP material, elastic outer lining 120 is made of thermoplastic polyester elastomer, and thermoplastic polyester elastomer is exactly TPEE material, above-mentioned
Bellows 100 made of two kinds of materials, can be improved the number of stretching, with the difference of the proportion of two kinds of materials, stretch
The available huge promotion of number is to keep bellows 100 more durable, not when stretching is opened in simple terms
Easily burst apart.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
