Description

The joint of quick joining water pipe

The present invention relates to a kind of water pipe connecting means.

The water pipe purposes is various, such as domestic water, the washing bay, plant husbandry ... or the like, often running into water pipe falls short of, the situations that must be connected with water inlet with another or two, its bridging mode, be that bore with the water pipe two ends pushes socket mutually with axial direction, often get loose because of hydraulic pressure is excessive, or when needs suspend to supply water, must go to water tap and bring in and close current, just can stop to supply water, therefore produce unnecessary waste, because of affecting water pipe in the middle of using or needing pressurization that connected portion is thrown off, at this moment, the user must remove to close water tap again again, to the water pipe two ends connected portion is packaged again, also to run to then turn on the tap, so loaded down with trivial details, can bring inconvenience.

The purpose of this invention is to provide a kind of novel water pipe adapter of constructing, water pipe is not held and binding end can be done firmly closely to be connected fast, and also can end current at once during dismounting, reaches easy to use, installing/dismounting effect rapidly.

According to the joint of a kind of quick joining water pipe of the present invention, mainly comprise a public access seat and reach and the supporting female joint chair of public access seat, wherein:

This public access seat is to connect end by socket end with mesoporous channels and pipe to combine, the mesoporous channels of this socket end extends to form a fore-set forward, and make fore-set and this socket end inner edge form an annular containing space, and this socket end end connects end with pipe and joins, and connects end for this public access seat with pipe and joins with water pipe; Cover T-Ring that this mother's joint chair is also established by the phase intercommunication and pipe connect termination and close and form, this cover T-Ring is to match with the socket end containing space of this public access seat, inserted the location that joins in this containing space for overlapping T-Ring, this pipe connects to be held and this cover T-Ring bolt, the other end then joins with water pipe, and this pipe connects end and establishes a normally closed valve rod with this socket interannular, this valve rod is to extend to be located on the washer of a bearing in this pipe connects end, this washer is provided with hole, and between washer and valve rod, be provided with elastic element, make valve rod become normally off.

By above-mentioned structure, fashionable with female joint chair cover when the public access seat, this socket ring set is gone into the containing space of public access seat, and the fore-set of while by this public access seat backs down normally closed valve rod, and the water pipe of two ends is communicated.

Now lift a preferred embodiment and cooperate the graphic back that is illustrated in:

Figure one is the three-dimensional exploded view of a preferred embodiment of the present invention;

Figure two is the sectional views before a preferred embodiment of the present invention combination;

Figure three is the sectional views after a preferred embodiment of the present invention combination;

Figure four is safety valve effect schematic representation in a preferred embodiment of the present invention.

See also figure one, the joint of quick joining water pipe of the present invention, mainly comprising a public access seat (10) reaches and the supporting female joint chair (20) of public access seat (10), wherein: this public access seat (10) is to connect end (12) by socket end (11) and pipe to be spirally connected mutually and to form, this socket end (11) inside is hollow tubular, and extend into a hollow fore-set (111), this fore-set (111) and a sheathed waterproof washer (112) in the appropriate position to the end; This socket end (12) forms an annular containing space (113) between this fore-set (111), and establishes a locating stud (114) on socket end outer rim, utilizes the female joint chair (20) of this containing space (113) and dowel (114) socket; This socket end (11) connects end (12) with this pipe of screw thread interlocking, connect in socket end (11) and pipe and to establish a safety valve (13) between end (12), this safety valve (13) is by stopper rod (131), spring (132) and the washer (133) with perforation combine, the through hole of this stopper rod (131) end in just can inaccessible socket end (11), and stopper rod (131) tail end penetrates washer (133), makes stopper rod (131) open or to close because of the change of hydraulic pressure under spring (132) elastic force effect; This pipe connects end (12) and is provided with screw section (121) and tapered slope (122), water pipe (14) can be squeezed and be placed on this tapered slope (122), be screwed with the collar (123) that is provided with internal thread and this screw section (121) again, can reach the effect of location water pipe (14); What deserves to be mentioned is that the terminal joint end (124) that matches with this tapered slope (122) that forms of this collar (123) can supply complete packing water pipe (14), and needn't worry that it can come off.

This mother's joint chair (20) comprises a cover T-Ring (21) that matches with the containing space (113) of public access seat (10), this cover T-Ring (21) is screwed into pipe and connects in the end (22), and in through hole between the two axial arrangement one normally closed valve rod (231), spring (232) and washer (233); This normally closed valve rod (231) end is formed with the cupule (235) of plural perforation (234), and valve rod (231) tail end is nested with spring (232) and penetrates washer (233), borrows the elastic force of spring, makes the inaccessible cover of valve rod (231) T-Ring (21); The ora terminalis that this pipe connects end (22) is provided with " it " type locating slot (221) that matches with locating stud (114), the other end also is provided with screw section (222) and tapered slope (223), for engaging with the collar (23) and water pipe (24), and this collar (23) end also is provided with joint end (236), because it is identical with this public access seat (10) that the pipe of female joint chair (20) connects the structure and the mode of end (22) connection water pipe (24), do not repeat them here.

Respectively with public access seat (10) and axially winding of female joint chair (20), see also figure two and be the side view after making up, at this moment, public, female joint chair (10) (20) is fit not as yet, valve rod (231) in female joint chair (20) keeps normally off, and the water in the water pipe (24) can't flow out, when public access seat (10) (sees also figure three) with locating stud (114) when locating slot (221) is inserted in female joint chair (22), this fore-set (111) just can withstand the cupule (235) of this valve rod (231), valve rod (231) is opened, cover T-Ring (21) is then inserted in the interior containing space (113) of socket end (11), simultaneously, current in the water pipe (24) are by the hole of washer (233), flow to the duct of fore-set (111) through the perforation (234) of valve rod (231), following current and the water that comes can back down safety valve (13) is connected water pipe (24) and water pipe (14).

Because, this device just can make water connect along backed down valve rod (231) by fore-set (111), and when backing down valve rod (231), locating stud (114) and locating slot (221) promptly fasten immediately, so not having water when engaging oozes out, also can when separating, make valve rod (231) closure in the time of separately,, not have and engage misgivings difficult and that current leak so effect is excellent in use; Moreover, water pipe (14) is if be subjected to tortuous compressing in use, tend to make the hydraulic pressure in the water pipe (14) too high, and the water of water pipe (24) increases continually, be very easy to make water pipe (14) because the too high and explosion of hydraulic pressure, Gu Benfamingte establishes a safety valve (13) in public access seat (10), if the hydraulic pressure of water pipe (14) is too high, safety valve (13) is because of the hydraulic pressure that is subjected to water pipe (14) and the elastic force effect of spring (132), block to live the interior through hole of socket end (22) and close, and do not cause too high hydraulic pressure to break earth water pipe (14), shown in figure four.

In sum, the present invention is a kind of joint of quick joining water pipe, and its use is quick, easy, firm, and can open and close current at any time.
