The model utility content
In view of above-mentioned existing in prior technology problem, the utility model provides a kind of universal joint, by window is set on screwed pipe, window is provided with the transparent picture that is complementary with it, just can be clear that by this transparent picture whether water pipe is in place like this, reduce the water pipe installation time, increase work efficiency.
In order to reach above-mentioned technique effect, the utility model 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 described pipe of press-offing is connected with described nut, 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 metal back-off ring, described packing ring and described O-ring seal are superimposed in turn and fixed in the cavity of described nut and the formation of described screwed pipe, described metal back-off ring is provided with a plurality of fins with locking back-off near described packing ring side, described screwed pipe is provided with at least one window, is provided with the transparent picture that is complementary with described window in the described window.
As the utility model universal joint preferred implementation, described nut outer installment has screw thread.
As the utility model universal joint preferred implementation, described press-off the pipe and described metal back-off ring be fixed into one.
As the utility model universal joint preferred implementation, described packing ring and described O-ring seal are fixed into one.
Implement the utility model, have following beneficial effect: by window is set on screwed pipe, window is provided with the transparent picture that is complementary with it, just can be clear that by this transparent picture whether water pipe is in place like this, reduce the water pipe installation time, increase work efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment 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 embodiments more of the present utility model, 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 an embodiment's of the utility model universal joint a structural representation.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, Fig. 1 is an embodiment's of the utility model universal joint a structural representation.This universal joint comprises nut 1, screwed pipe 6, press-off pipe 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, the pipe 2 of press-offing is connected with nut 1, 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, and snap ring 21 just can be fixed in the nut 1 like this.Press-off pipe 2, metal back-off ring 3, packing ring 4 and O-ring seal 5 is superimposed in turn and fixed in the cavity that nut 1 and screwed pipe 6 form, 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.Screwed pipe 6 is provided with at least one window 62, is provided with the transparent picture 621 that is complementary with window 62 in the window 62.
Concrete, in order to increase resistance, nut 1 outer installment has screw thread 12, can be easy to nut 1 and screwed pipe 6 are screwed in together by screw thread 12.
Need to prove that this window also can be applied on valve or other pipe fittings.
Metal back-off ring 3, packing ring 4 and O-ring seal 5 are superimposed in turn and fixed in the cavity of nut 1 and screwed pipe 6 formation, 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 push the pipe of press-offing and water pipe and joint can be separated, and this universal joint can reuse simultaneously, help environmental protection, reduce cost.
When needs are installed water pipe, at first the transparent picture 621 that sees through window 62 aligns water pipe with joint, water pipe and joint are in vertical position, then water pipe is pushed in the pipe 2 of press-offing by through hole 11, fin 31 up to metal back-off ring 3 is buckled together water pipe and joint tightly, reaches 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, the utility model universal joint is by being provided with window on screwed pipe, window is provided with the transparent picture that is complementary with it, just can be clear that by this transparent picture whether water pipe is in place like this, reduce the water pipe installation time, increase work efficiency.
Above disclosed only is several preferred embodiments of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
