Abstract

The utility model discloses an effective joint of hydraulic pressure, including a pipe body, the outside lower part of body is equipped with the external screw thread, external screw thread outside spiro union has the nut, the upper portion of body is equipped with ring channel and ring flange, the ring flange is located the upside of ring channel, just the both sides of ring flange are equipped with the through -hole, this effective joint of hydraulic pressure, through the external sleeve with the hydraulic pressure coupling and junction block setting together, when installation hydraulic pressure pipe, will not external sleeve, the nut installs with junction block elder generation post assembling again, and do through the flange dish and connect and sealed acting on, the joint end sets up the sealing washer, effective sealing connection department, preventing leakage. Adopt O type circle can play better sealed effect, the middle part makes the flexibility of this joint stronger through telescopic tube connector simultaneously, and application scope is broader, and through having practiced thrift the equipment time, has improved work efficiency, has also reduced the disqualification rate of product simultaneously, has practiced thrift manufacturing cost.

Description

A kind of joint of hydraulic tube
Technical field
This utility model relates to hydraulic fittings technical field, the joint of a kind of hydraulic tube.
Background technology
Along with economic develops rapidly, the demand of various plant equipment the most constantly rises, and in plant equipment, hydraulic pressure system is under the overall leadership Joint is one of indispensable part.At present conventional hydraulic coupler is that sleeve, junction block, nut independently set mostly Put, first assemble during installation, owing to assembling can take part-time, thus cause inefficiency, also easily produce and do not conform to Lattice product, adds production cost virtually.Hydraulic technique application is widely.Hydraulic technique utilizes hydraulic oil transmission pressure Power.The conveying of hydraulic oil is the most crucial in hydraulic technique.Hydraulic oil has higher pressure.Between pipeline of the prior art Attachment structure complicated, install and use equal inconvenience, and the sealing of junction be poor, easily causes leakage.And motility is poor, Range is little, and in use, some fluid pressure line needs Assembling, and baroque adaptor needs by spy Different instrument, it is impossible to Fast Installation, for this it is proposed that the joint of a kind of hydraulic tube.
Utility model content
The purpose of this utility model is to provide the joint of a kind of hydraulic tube, to solve proposition in above-mentioned background technology Problem.
For achieving the above object, this utility model following technical scheme of offer: the joint of a kind of hydraulic tube, including pipe Body, the left side seam of described body is provided with sealing ring, and the right side of described sealing ring is provided with back-up ring, and the right side of described back-up ring is provided with Strengthening the collar, the connection port left by telescoping tube both sides between described body and described body is socketed, the outside of described body Bottom is provided with external screw thread, is bolted with nut outside described external screw thread, and the top of described body is provided with cannelure and ring flange, described Ring flange is positioned at the upside of cannelure, and the both sides of described ring flange are provided with through hole.
Preferably, described sealing ring is O type circle, and O type circle protrudes from storage tank.
Preferably, the inwall of described through hole is provided with general female thread.
Compared with prior art, the beneficial effects of the utility model are: the joint of this hydraulic tube, by being connect by hydraulic tube The external sleeve of head is set together with junction block, when installing hydraulic tube, it is not necessary to by external sleeve, nut and junction block first group Installing after dress, one end uses bite type to connect again, and the other end uses nut to be detachably spirally connected with external screw thread, it is convenient to will Many tube heads connect and connect, and are done by ring flange and connect and sealing function, and joint end arranges sealing ring, can the effective company of sealing Meet place, prevent from revealing.Use O can play better seal effect, simultaneously in the middle part of connect by telescoping tube, make this joint clever Activity is higher, and the scope of application is broader, and by having saved built-up time, improves work efficiency, also reduce product simultaneously The disqualification rate of product, has saved production cost.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 sealing ring, 2 back-up rings, the 3 reinforcement collar, 4 bodys, 5 telescoping tubes, 6 connection port, 7 ring flanges, 8 through holes, 9 rings Shape groove, 10 external screw threads, 11 nuts.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of technical scheme of this utility model offer: the joint of a kind of hydraulic tube, including body 4, institute The left side seam stating body 4 is provided with sealing ring 1, and the right side of described sealing ring 1 is provided with back-up ring 2, and the right side of described back-up ring 2 is provided with Strengthening the collar 3, the connection port 6 left by telescoping tube 5 both sides between described body 4 and described body 4 is socketed, described body 4 Outer lower portion be provided with external screw thread 10, be bolted with nut 11 outside described external screw thread 10, the top of described body 4 is provided with cannelure 9 and ring flange 7, described ring flange 7 is positioned at the upside of cannelure 9, and the both sides of described ring flange 7 are provided with through hole 8.
Further, described sealing ring 1 is O type circle, and O type circle protrudes from storage tank, can play better seal effect Really, it is ensured that the stability of pipe joint, contrast common joint, more there is advantage.
Further, the inwall of described through hole 8 is provided with general female thread, dismantles more efficient and convenient, when saving certain Between, loosening problem will not be there will be as other mounting means, cause poor stability.
The joint of this hydraulic tube, by being set together with junction block by the external sleeve of hydraulic fitting, is installing During hydraulic tube, it is not necessary to install after external sleeve, nut 11 first being assembled with junction block, one end uses bite type to connect again, The other end uses nut 11 to be detachably spirally connected with external screw thread 10, it is convenient to many tube heads is connected and is connected, and passes through flange Dish 7 does and connects and sealing function, and joint end arranges sealing ring 1, can effectively be tightly connected place, prevents from revealing.O is used to rise To better seal effect, simultaneously in the middle part of connected by telescoping tube 5, make the motility of this joint higher, the scope of application is broader, And by having saved built-up time, improve work efficiency, also reduce the disqualification rate of product simultaneously, saved and produced into This.
Embodiment the most of the present utility model, for the ordinary skill in the art, It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
