In view of above-mentioned existing in prior technology problem, the invention provides a kind of universal joint, pipe and metal back-off ring just can be closely together water pipe and joint by press-offing.
In order to reach above-mentioned technique effect, the invention provides a kind of universal joint, comprise nut, screwed pipe, the pipe of press-offing, metal back-off ring, packing ring and O-ring seal, described nut is provided with through hole, the diameter of the described Guan Yiduan that press-offs is less than described through-hole diameter, the described pipe the other end of press-offing is provided with snap ring, described snap ring diameter is greater than described through-hole diameter, described screwed pipe is provided with first screw thread, described nut inside is provided with second screw thread that is complementary with described first screw thread, the described pipe of press-offing, described metal back-off ring, described packing ring and described O-ring seal are superimposed in turn and fixed in described nut and the described screwed pipe cavity by described first screw thread and described second screw thread, and described metal back-off ring is provided with a plurality of fins with locking back-off near described packing ring side.
Correspondingly, described screwed pipe two ends are respectively arranged with first screw thread.
Correspondingly, described nut outside also is provided with the 3rd screw thread.
Correspondingly, described press-off the pipe and described metal back-off ring be fixed into one.
Correspondingly, described packing ring and described O-ring seal are fixed into one.
Implement the present invention, has following beneficial effect: be superimposed in turn and fixed in the cavity of nut and screwed pipe by will press-off pipe, metal back-off ring, packing ring and O-ring seal of first screw thread and second screw thread, form a universal joint, can easily water pipe and joint be closely together, simple in structure, easy to operate, good airproof performance, the while convenient disassembly, only need push the pipe of press-offing can separate water pipe and joint, and this universal joint can reuse, and helps environmental protection, reduce cost, meet consumers' demand.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of universal joint of the present invention;
Fig. 2 is the cross-sectional view of Fig. 1 universal joint.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who is obtained under the creative work prerequisite.
Referring to Fig. 1, Fig. 1 is the structural representation of universal joint of the present invention.This universal joint comprises nut 1, screwed pipe 6, press-off and manage 2, metal back-off ring 3, packing ring 4 and O-ring seal 5, nut 1 is provided with through hole 11, press-off the pipe 2 one ends diameter less than through hole 11 diameters, pipe 2 the other ends of press-offing are provided with snap ring 21, snap ring 21 diameters are greater than through hole 11 diameters, snap ring 21 just can be fixed in the nut 1 like this, screwed pipe 6 is provided with first screw thread 61, concrete, when needs prolong universal joint, screwed pipe 6 two ends are respectively arranged with first screw thread 61, just can be according to the required length of determining universal joint of user by first screw thread 61 is set respectively at screwed pipe 6 two ends.Nut 1 inside is provided with the second screw thread (not shown) that is complementary with first screw thread 61, press-off pipe 2, metal back-off ring 3, packing ring 4 and O-ring seal 5 is superimposed in turn and fixed in nut 1 and screwed pipe 6 cavitys by first screw thread 61 and second screw thread, metal back-off ring 3 is provided with a plurality of fins 31 with locking back-off near packing ring 4 sides, in the middle of actual mechanical process, this fin 31 can be iron plate or other rubber-like thin slices, play the back-off effect by this fin 31, water pipe and joint are closely together.
Concrete, in order to increase resistance, nut 1 outside also is provided with the 3rd screw thread 12, can be easy to nut 1 and screwed pipe 6 are screwed in together by the 3rd screw thread 12, the cross-sectional view that nut 1, press-off pipe 2, metal back-off ring 3, packing ring 4, O-ring seal 5 and screwed pipe 6 are combined as shown in Figure 2.
When needs are installed water pipe, at first water pipe is alignd with joint, be in vertical position, then water pipe is pushed into to press-off by through hole 11 and manages in 2, up to the fin 31 of metal back-off ring 3 water pipe and joint are buckled together tightly, reach the connection effect.Simultaneously,, can resist hydraulic pressure, prevent seepage, improve the sealing of universal joint because this universal joint the inside is equipped with O-ring seal 5.
When needs are separated water pipe and joint, only need the applying light pipe 2 of press-offing, the fin 31 of metal back-off ring 3 is opened, again water pipe one is drawn gently, just water pipe and joint can be separated, simple in structure, easy to operate.
In sum, a kind of universal joint that the embodiment of the invention proposes, be superimposed in turn and fixed in the cavity of nut and screwed pipe by will press-off pipe, metal back-off ring, packing ring and O-ring seal of first screw thread and second screw thread, form a universal joint, can easily water pipe and joint be closely together, simple in structure, easy to operate, good airproof performance, convenient disassembly only need be pushed the pipe of press-offing and water pipe and joint can be separated simultaneously, and this universal joint can reuse, help environmental protection, reduce cost, meet consumers' demand.
Above disclosed is several preferred embodiments of the present invention only, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
