Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
A four-way oil inlet pipe joint is shown in figures 1 to 4 and comprises an oil inlet pipe 1 and three oil outlet pipes 2 which are integrally formed with the oil inlet pipe 1, wherein the oil inlet pipe 1 and the oil outlet pipes 2 are both made of stainless steel, an annular groove 3 is formed in the outer peripheral wall of the oil inlet pipe 1, a spring gasket 4 is arranged in the annular groove 3, one end of the spring gasket 4 is fixedly connected to the bottom of the annular groove 3, the other end of the spring gasket 4 is fixedly connected with a sleeve 5 made of hard alloy, a chute 8 is formed in the outer peripheral wall of the oil inlet pipe 1, a sliding block 9 for clamping into the chute 8 is arranged on the inner peripheral wall of the sleeve 5, a clamping block 11 is arranged at one end, far away from the inner peripheral wall of the sleeve 5, of the sliding block 9 is perpendicular to the sliding block 9, a clamping groove 10 for inserting the clamping block 11 is formed in the bottom of the chute, the surface, far away from the spring washer 4, of the sleeve 5 is provided with a plurality of pressing parts 6 made of nitrile rubber, the pressing parts 6 are circumferentially arranged by taking the central axis of the sleeve 5 as the center, the pressing parts 6 are in a circular truncated cone shape, and a groove 7 is formed in one surface, far away from the sleeve 5, of the pressing parts 6.
When the metal hose is inserted into the oil inlet pipe 1, the pressing part 6 contacts with the limiting part of the metal hose firstly, the groove 7 is arranged on the pressing part 6, the pressing part 6 is more easily deformed at the groove 7 after being extruded by the limiting part of the metal hose, so that the groove 7 is expanded, two side surfaces of the groove 7 are gradually attached to the bottom of the limiting part of the metal hose, the contact area between the pressing part 6 and the limiting part of the metal hose is increased, further, the friction force is increased, the metal hose is prevented from sliding, after the groove 7 is completely expanded, a certain gap is formed between the inner part of the groove 7 and the limiting part of the metal hose, the air pressure in the gap is lower, so that a certain adsorption force is provided for the limiting part of the metal hose, the metal hose is not easy to loosen, and the sleeve 5 can be extruded by the limiting part to return along with the continuous screwing-in of a, thereby make spring washer 4 receive the extrusion atress of sleeve 5 to retract back, insert into oil pipe 1 back at metal collapsible tube's plug completely, spring washer 4 has an elasticity to sleeve 5 all the time to make sleeve 5 exert the extrusion force to metal collapsible tube's spacing portion, thereby make metal collapsible tube and oil feed joint's threaded connection more stable, thereby prevent that metal collapsible tube is not hard up.
Owing to be equipped with spout 8 and slider 9, thereby insert spout 8 through slider 9 and realized sleeve 5 at advancing the sliding connection on the oil pipe 1 outer wall, simultaneously because spout 8 is spacing to slider 9, sleeve 5 can only take place fore-and-aft slip advancing oil pipe 1 outer wall to make sleeve 5 can not rotate thereupon because of metal collapsible tube's spacing portion is rotatory, thereby avoid the anti-skidding effect of pressing part 6 to receive the influence.
Owing to be equipped with fixture block 11 and draw-in groove 10 for after slider 9 inserts spout 8, through draw-in groove 10 to fixture block 11 spacing, make the connection of slider 9 in spout 8 more stable, prevent that sleeve 5 from taking place to rock.
Because sleeve 5 is made by carbide, carbide has the good performance that hardness is high, wear-resisting, intensity and toughness are better for sleeve 5 intensity, hardness are high, and the support effect that plays after the metal collapsible tube inserts is better and also is difficult to damage when non-deformable.
Because the pressing piece 6 is made of nitrile rubber, the nitrile rubber has the characteristics of high wear resistance and strong bonding force, so that the pressing piece 6 has high wear resistance and strong bonding force, the pressing piece 6 is easy to deform, and the anti-skidding effect is better while the abrasion is not easy to occur.
Because the oil inlet pipe 1 and the oil outlet pipe 2 are both made of stainless steel, the stainless steel has the characteristics of high hardness and excellent corrosion resistance, so that the oil inlet pipe 1 and the oil outlet pipe 2 are not easy to rust and have higher hardness, and the oil inlet pipe and the oil outlet pipe do not need to be periodically cleaned and replaced due to damage or rust, thereby reducing the cost.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
