Abstract

A rapid joint with oil film comprises a female joint parent with a through-hole, a steel ball inlayed in the through-hole and a male joint cylinder, wherein, a concave groove and a cutting ferrule are arranged on the surface of the cylinder. The female joint parent matches with the male joint cylinder by sealing. The steel ball on the parent is clipped into the concave groove on the surface of the cylinder. The cutting ferrule is arranged on the outer surface of the parent. The utility model further comprises a pulling sheath which is arranged on the surface of the male joint cylinder and connected with the cutting ferrule on the female joint by the inner screw of the pulling sheath. An insert retainer is arranged on the male joint cylinder. The tooth-type rotating keys are arranged on the female joint and the pulling sheath. The utility model has the advantages that the joint can not drop off or be vibrated off, thereby increasing secondary insurance and improving safety performance greatly. The insert retainer is arranged on the male joint cylinder. A screw mouth which is screwed by the safety pulling sheath is arranged on the outer loop of the cutting ferrule of the female joint, thereby screwing with the safety pulling sheath and judging whether the female joint is loaded in correct position at the same time. The tooth-type rotating keys are arranged on the female joint to enable the unloading operation to be convenient by rotating, thereby being convenient for operation and tool work.

Description

A kind of oil film rapid pipe joint

Technical field

The utility model relates to a kind of oil film rapid pipe joint.

Background technique

Oil film rapid pipe joint comprises male joint cylinder, female parent, female joint as take place because of drop, collision or extrusion-deformation, the jump ring in the cutting ferrule very easily is out of shape and the evagination ejection, make cutting ferrule can't arrive original position, come off as being easy to after the attaching, and cause a large amount of leakage of oils of bearing, burn out a bearing; Whether put difficult judgement after the female joint attaching fully in place; Producing vibration when rolling very easily shakes joint to take off; And materials such as male joint cylinder, female parent, cutting ferrule all adopt copper material, in dismounting, install or put in the process, drop, collide or push, and are easy to distortion, damage, and can only change joint, expend time in influence production; The operating personnel accomplishes not drop, do not collide, do not push difficulty in operation bigger, because of operation, work condition environment poor, cannot say for sure to demonstrate,prove and be not damaged in its joint operation or be out of shape, if any slight deformation, the operating personnel is difficult to find, oil impregnate, leakage of oil more easily takes place and influence bearing working life and energy water quality; This joint safety reliability is poor, and use in the place that is not suitable for the work condition environment difference, and secondly, the life-span is short, change frequently, and the cost height, the frequency height is produced in influence.

Summary of the invention

The purpose of this utility model is to provide after a kind of attaching or produces and can not come off or shake and take off, operation oil film rapid pipe joint easily in rolling.

For achieving the above object, the utility model comprises a female joint parent, establishes a through hole on the parent, and through hole is embedded with a steel ball; One male joint cylinder, damaged surface is provided with a groove; One cutting ferrule;

Described female joint parent and male joint cylinder are sealed and matched, and the steel ball on the parent snaps in the groove of damaged surface; Described cutting ferrule is set in the parent outer surface, also comprises and helping pull a cart, and this is helped pull a cart and is sheathed on the male connector post surface, and connects with cutting ferrule on the female joint with its internal thread.

On male joint cylinder, be provided with a back-up ring.

Described female joint and help pull a cart on tooth-like rotatable key is housed.

Described female, male joint, cutting ferrule and the material of helping pull a cart adopt steel material.

Advantage of the present utility model is:

1. be equipped with on the male joint cylinder and help pull a cart, female head is tightened helping pull a cart on by male head after the attaching to be rotatably connected with cutting ferrule silk thread mouth on the female head, female head is after attaching or produce and can not come off or shake and take off in rolling, has increased the secondary insurance, and Safety performance improves greatly.

2. tighten with the rotation of helping pull a cart female joint cutting ferrule outer ring, screw-thread fit, make it to tighten with helping pull a cart to dock, simultaneously, also be to judge whether female joint installs to the criterion of position, as it is stubborn not in place or stubborn motionless to help pull a cart, illustrating that female joint not installs or is unkitted puts in place, can remind the operating personnel to reinstall, if determine can't this female joint distortion of installation instructions or damage or snap ring may be out of shape, need to change female joint, therefore, significantly reduced the incidence rate of the accident that burns out because of the bearing that joint comes off or fortuitous event causes.

3. on the female joint tooth-like rotatable key is housed, makes to rotate when removing stage makeup and costume to make operation convenient, be convenient to operation, also be convenient to tool operation.
