Abstract
The utility model discloses a fast charging pipe joint assembly of a lubrication system, comprising a joint, an O-shaped seal ring, a bush, a gasket and a claw card. In the joint that is arranged out of the connected nylon pipe fitting, the arrangement from left to right is as follows: the O-shaped seal ring is arranged, the bush is arranged on the step surface of the internal end of the joint, the claw card that is separated by the gasket and the inner ring of the claw card has an equal divided and outer convex elastic plate is arranged on the end surface of the bush, a joint external port of one end of the claw card is extruded to form a closing-in, a screw thread is arranged on the outer of the joint near one end of the claw card, and the O-shaped seal ring is arranged in a sinking and cutting groove of the screw thread. When a connector is inserted into the nylon pipe, the elastic plate amplexed automatically due to that the external diameter of the nylon pipe is larger than the controlling diameter of the elastic plate in free status, and the connected pipe fitting is firmly jammed by the elastic plate under external force, so the connected pipe fitting can not reversely separate; as external screw thread is arranged on the outer of the joint and is sleeved with the O shaped seal ring, the joint is matched and sealed with the corresponding pipe fitting with inner screw thread. The utility model has the advantages of simple structure, convenient assembly, no oil leakage and uneasy separation.
Description
Affiliated technical field
The utility model relates to a kind of pipe joint, particularly relates to a kind of fast holding pipe joint assembly of lubrication system.
Background technique
At present the pipe joint of lubrication system commonly used is a kind of Bite type fittings, adopts the FERRULETYPE sealing, and the problem of its existence is: adopt the influence of cutting ferrule sealing extruding force when the degree of part (nylon tube) is subjected to nut screwing clamping in succession, the sealability instability; Owing to easy resiliently deformables of connected piece such as nylon tubes, must add the lining of a metallic material system at jointing, the result dwindles the aperture of jointing pipeline, produces disadvantageous damping phenomena when lubricant oil is carried.In addition, also there is assembling inconvenience in this Bite type fittings when as installed, and the installation requirement height in use is prone to leakage of oil, pipe and situation such as deviates from.
Summary of the invention
That the purpose of this utility model provides is simple in structure, sealability stable, connect the fast holding pipe joint assembly of a kind of lubrication system reliable, easy for installation.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise joint, " O " RunddichtringO, lining, pad, pawl card.Be contained in and be connected in the outer joint of nylon pipe, the end face that lining, lining are housed on the step surface of " O " RunddichtringO, joint interior edge face is housed from left to right successively to be equipped with its inner ring of separating with pad and to have five equilibrium outwards to protrude the pawl card of spring sheet, the nylon pipe external diameter is greater than the control diameter of spring sheet free state, the joint external port extruding of pawl card one end is closed up, joint near pawl card one end has screw thread outward, is with Ling Yi Ma " O " RunddichtringO in the undercut groove of screw thread.
The utility model compared with prior art, the useful effect that has is: when connected pieces such as nylon tube insert, because the nylon tube external diameter is greater than the control diameter of spring sheet free state, the spring sheet automatic wrapping, and spring sheet tightly blocks connecting tube under external force, and it can not oppositely be got loose; There is outside thread the outside of joint, is with " O " RunddichtringO, makes it and the pipe fitting fitted seal that has internal thread accordingly.The utlity model has simple in structure, easy for installation, oil-proof, advantage such as be difficult for getting loose.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of pawl card.
Among the figure: the spring sheet of 1 joint, 2 " O " RunddichtringO, 3 " O " RunddichtringO, 4 linings, 5 pads, 6 pawl cards, 7 nylon tubes, 8 pawl cards
Embodiment
As shown in Figure 1 and Figure 2, comprise joint 1, " O " RunddichtringO, lining 4, pad 5, pawl card 6.Be contained in the joint 1 outside the connecting tube 7, the end face that lining 4, lining 4 are housed on the step surface of " O " RunddichtringO 2, joint 1 interior edge face is housed from left to right successively to be equipped with its inner ring of separating with pad 5 and to have five equilibrium outwards to protrude the pawl card 6 of spring sheet 8, nylon pipe 7 external diameters are greater than the control diameter of spring sheet 8 free states, the joint external port extruding of pawl card 6 one ends is closed up, outside the joint 1 near pawl card 6 one ends screw thread is arranged, be with Ling Yi Ma " O " RunddichtringO 3 in the undercut groove of screw thread.
" O " RunddichtringO 2 that is equipped with in the said joint 1 is 2～3; Among Fig. 1 be 2.
The pawl card 6 that the end face of said lining 4 is equipped with its inner ring of separating with pad 5 has five equilibrium outwards to protrude spring sheet 8 is 2～3; Spring sheet 8 is 3 among Fig. 1, and pawl card 6 is 2.
Inside one end of joint 1 is equipped with 2 " O " RunddichtringOs, seals under the extruding of connecting tube (nylon tube) 7; The other end is equipped with lining 4,2 pawl cards 6 are housed on the end face of lining 4, separate with pad between the pawl card 6, the external port extruding of joint 1 is closed up, make pawl card 6 axially locating in joint 1, when pipe joint was installed, the spring sheet 8 on the pawl card 6 tightened connected pieces such as nylon tube under external force, it can not oppositely be got loose, and nylon tube 7 is being vibrated or is being difficult for getting loose during pulling force.There is outside thread the outside of joint 1, and " O " RunddichtringO is arranged, and makes it and the pipe fitting fitted seal that has internal thread accordingly.
