Abstract

A quick hose connector relates to the technical field of fluid pipeline connection. Including hexagonal double screw connector, the inner tube, lock nut, the chucking cover, the inner tube suit is in the port of hexagonal double screw connector one end, and spacing through the step between them, be provided with the opening ring channel outwards between inner tube and the hexagonal double screw connector, the hose suit is in the ring channel, the chucking cover suit is on the connecting end of hose, lock nut suit is on the chucking cover, and with hexagonal double screw connector threaded connection, chucking cover and lock nut, it is spacing through the step respectively between the hose, thereby realize the axial positioning of chucking cover, the periphery and the chucking cover of inner tube are provided with round annular rib in radial corresponding position, annular rib and the chucking cover cooperation are with the hose chucking on the inner tube. The utility model discloses not only solved among the prior art mechanical vibration occasion fluid pipeline sealing thread and probably produced not hard up problem because of the vibration to through bolt locking hose, have the advantage of connecting convenient, swift.

Description

Quick hose coupler

Technical Field

The utility model relates to a fluid pipeline connects technical field, specifically is a quick hose coupler.

Background

In the prior art, the hose connectors are often mounted on movable and vibrating mechanical equipment through hose connectors, so that the hose connectors are required to be convenient to disassemble, have certain stability and be suitable for vibrating working environments.

At present, various quick-dismantling hose joints are used in industrial application, but the joints have poor stability and cannot be suitable for a vibrating working environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a quick hose coupler has stability height, can adapt to the operational environment's of vibration advantage.

The technical scheme for realizing the purpose is as follows: a quick hose coupling, characterized in that: the inner pipe is sleeved in a port at one end of the hexagonal double-screw connector and is limited by a step, an annular groove with an outward opening is formed between the inner pipe and the hexagonal double-screw connector, the hose is sleeved in the annular groove, the clamping sleeve is sleeved on the connecting end of the hose, the locking nut is sleeved on the clamping sleeve and is in threaded connection with the hexagonal double-screw connector, the clamping sleeve is limited by the step and is axially positioned with the clamping sleeve, the clamping sleeve is axially positioned, the periphery of the inner pipe and the clamping sleeve are provided with a circle of annular ribs at radial corresponding positions, and the annular ribs and the clamping sleeve are matched to clamp the hose on the inner pipe.

Furthermore, a circle of annular ribs are arranged at the radial corresponding positions of the periphery of the inner pipe and the clamping sleeve.

Further, a sealing ring is arranged between the inner end of the inner pipe and the hexagonal double-thread connector.

Furthermore, the middle part of the periphery of the hexagonal double-screw connector is provided with a circle of annular flange, and an elastic pad is clamped between the annular flange and the locking nut.

The utility model has the advantages that:

quick water pipe head not only solved among the prior art not hard up problem that mechanical vibration occasion fluid pipeline sealing thread probably produced because of the vibration to through bolt locking hose, have the advantage of connecting convenient, swift.

Drawings

FIG. 1 is an exploded view of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses a hexagonal double screw joint 1, inner tube 2, lock nut 3,

chucking cover

4, 2 suits of inner tube are in the port of 1 one end of hexagonal double screw joint, and spacing through the step between, be provided with sealing washer 10 between the inner of inner tube 2 and the hexagonal double screw joint 1, be provided with opening ring channel 5 outwards between inner tube 2 and the hexagonal

double screw joint

1, 6 suits of hose are in

ring channel

5, 4 suits of chucking cover are on the connecting end of

hose

6, 3 suits of lock nut are on chucking cover 4, and with 1 threaded connection of hexagonal double screw joint, the middle part of 1 periphery of hexagonal double screw joint is provided with round annular flange 7, it is provided with bullet pad 8 to press from both sides tightly between annular flange 7 and the lock nut 3.

The axial positioning of the clamping sleeve 4 is realized by limiting the clamping sleeve 4 through steps between the clamping sleeve 4 and the locking nut 3 and between the clamping sleeve 6, a circle of annular rib 9 is arranged at the radial corresponding position of the periphery of the inner tube 2 and the clamping sleeve 4, and the annular rib 9 is matched with the clamping sleeve 4 to clamp the hose 6 on the inner tube 2.

As a further explanation of the present embodiment, the hose 6 in the present embodiment is preferably a silicone rubber reinforced tube.

When connecting hose 6, with 6 suit of hose in the ring channel 5 between inner tube 2 and the double thread connector of hexagonal 1, twist lock nut 6, drive chucking cover 5 extrusion hose 6, and realize the locking of hose 6 with the annular rib 9 cooperation of 2 peripheries of inner tube, bounce-back extrusion lock nut 3 under lock nut 3's thrust is filled up to the bullet simultaneously 7, the frictional force of 7 screw threads of lock nut and the double thread connector of hexagonal 1 screw thread has been increased, it is not hard up between 7 and the double thread connector of hexagonal 1 screw threads to have avoided long-time vibration application occasion lock nut, thereby make the utility model discloses can be applicable to and work under the vibration environment.
