Description

Technical Field

[0001] This invention belongs to the technical field of quick-connect anti-detachment connectors, specifically relating to a quick-connect hose and an anti-detachment connector. Background Technology

[0002] Hoses, as a type of pipeline for conveying media, are commonly used for steam transportation. Currently, hoses basically use two sealing methods: flat gaskets or conical gaskets. Both of these sealing methods require nuts to be tightened on the joints. However, hoses often need to move during use, which can easily cause the hose end joints to loosen and leak. Under high-pressure conditions, there are also safety risks. At the same time, tightening and loosening hose connections with nuts in confined spaces is inconvenient. The torque of the nuts is difficult to control, and threaded installation can easily cause the hose to twist, resulting in a significant reduction in the service life of the hose and the disadvantage of loosening during use. Summary of the Invention

[0003] This invention aims to provide a quick-install hose and anti-detachment connector, which has a good sealing effect and is convenient and quick to install and remove. It solves the problems that both flat gasket and conical head sealing methods require nuts to be tightened on the connector, which are inconvenient to install and remove, easy to loosen, and affect the service life of the hose.

[0004] Therefore, the technical solution adopted by the present invention is as follows: a quick-connect hose and an anti-detachment connector, characterized in that: it includes a hose and an anti-detachment connector, the hose end is provided with a connecting pipe and a locking buckle fitted on the connecting pipe, the outer end of the connecting pipe is provided with a limiting protrusion ring placed in the locking buckle, the outer end of the locking buckle is provided with a toothed structure facing the central axis in a circumferential direction, the tooth width and tooth spacing of the toothed structure are the same, the anti-detachment connector includes a connector body, an elastic element, and a locking ring, the locking ring is fitted on the connector body, the fixed end of the elastic element is fixed on the connector body, and the telescopic end abuts against the locking ring, the inner end of the connector body is circumferentially... A second toothed structure is provided, matching the size of the first toothed structure. The locking buckle can be moved axially by turning, causing the second toothed structure to intersect with the first toothed structure and pass through into the locking buckle. The end of the locking ring away from the elastic element is provided with horizontal insert teeth that match the size of the gap between adjacent teeth of the first and second toothed structures. The second toothed structure and the horizontal insert teeth are interspersed. When the knob is locked until the toothed structure two located in the locking buckle is aligned and overlapped with the tooth shape of the first toothed structure, the horizontal insert teeth can be inserted into the first toothed structure with the help of the elastic element to form a closed surface. The second toothed structure is simultaneously locked by the first toothed structure and cannot be removed.

[0005] As a preferred embodiment of the above scheme, the tooth structure one, tooth structure two, and horizontal insert teeth all adopt a six-tooth structure with uniform circumferential arrangement to fully ensure a tight connection.

[0006] More preferably, the outer end of the connector is fitted with a combined dynamic seal, which includes a guide ring and a sealing ring, thereby satisfying the sealing between the connector and the body of the joint in relative axial sliding and rotational movements, ensuring the reliability of quick hose installation.

[0007] More preferably, the width of the latch cavity matches the sum of the thicknesses of the limiting protrusion and the toothed structure, thereby ensuring that the limiting protrusion and the toothed structure can be simultaneously and tightly placed in the latch cavity.

[0008] More preferably, the elastic element is a spring, with one end fixed to the connector body by an elastic element mounting block, and the other end generating a thrust under pressure to push the horizontal insert of the locking ring into the gap between adjacent teeth of the toothed structure.

[0009] The beneficial effects of this invention are:

[0010] (1) Compared with the two sealing methods of using flat gaskets or cones, both of which require nuts to be tightened on the joint, this application uses a special anti-detachment joint that is connected to the hose. The hose does not need to be tightened with nuts, so there is no possibility of loosening. Moreover, the hose can rotate itself when the equipment moves or during installation, eliminating the generation of torque. The hose is not subject to torque when it moves with the equipment, thereby improving its service life.

[0011] (2) Compared with the operation nut tightening which requires more operating space, this solution only requires aligning the anti-loosening connector with the end of the hose, and then rotating the locking buckle axially to make the second toothed structure inside the connector body pass through the first toothed structure of the locking buckle and enter the locking buckle. Then, the horizontal insert teeth of the locking ring are inserted into the gap between adjacent teeth of the first toothed structure under the boosting force generated by the pressure of the elastic element to reset and form a closed surface. The second toothed structure is simultaneously locked by the first toothed structure and cannot be removed, thus completing the locking. The operation is simple, requires little operating space, and is very quick to install. The toothed locking method also has a foolproof effect in the structural design. The limiting protrusion ring at the outer end of the connector is placed in the locking buckle, thereby axially limiting the locking buckle. The structure is interlocked, with a novel concept and ingenious design.

[0012] In summary, the present invention has the advantages of a stable connection without loosening, extended service life, simple operation, and small installation space requirement. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0017] Combination Figure 1 — Figure 3 As shown, a quick-connect hose and anti-detachment connector are composed of a hose 1 and an anti-detachment connector 2.

[0018] The end of the hose 1 is provided with a connector 11 and a locking buckle 12 fitted on the connector 11.

[0019] The outer end of the connector 11 is provided with a limiting protrusion 111, which is placed inside the latch 12 to limit the axial movement of the latch 12.

[0020] The outer end of the connector 11 is fitted with a combined dynamic seal, which mainly consists of a guide ring 13 and a sealing ring 14.

[0021] The outer end of the latch 12 is provided with a toothed structure 121 facing the central axis.

[0022] The tooth width and tooth spacing of tooth structure 121 are the same.

[0023] The anti-detachment connector 2 consists of a connector body 21, an elastic element 23, and a locking ring 24.

[0024] The locking ring 24 is fitted onto the connector body 21.

[0025] The fixed end of the elastic element 23 is fixed to the connector body 21, and the telescopic end abuts against the locking ring 24.

[0026] The inner end of the connector body 21 has a toothed structure 211 circumferentially arranged on the outer wall, which matches the size of the toothed structure 121.

[0027] The locking buckle 12 can be moved axially by rotating it, so that the toothed structure 211 and the toothed structure 121 intersect and pass through into the locking buckle 12.

[0028] The locking ring 24 has a horizontal insert tooth 241 at one end away from the elastic member 23, which is circumferentially provided with a tooth 241 that matches the gap size between adjacent teeth of tooth structure 121 and tooth structure 211.

[0029] The tooth-shaped structure 211 and the horizontal insert tooth 241 are arranged alternately.

[0030] When the toothed structure 211 located within the knob lock 12 is aligned and overlapped with the toothed structure 121, the horizontal insert 241 can be inserted into the toothed structure 121 under the push of the elastic member 23 to form a closed surface. The toothed structure 211 is simultaneously locked by the toothed structure 121 and cannot be removed.

[0031] The elastic element 23 is preferably a spring, and one end is fixed to the joint body 21 by the elastic element mounting block 22, while the other end can generate a thrust under pressure to push the horizontal insert 241 of the locking ring 24 into the gap between adjacent teeth of the tooth structure 121.

[0032] Tooth structure 121, tooth structure 211, and horizontal insert tooth 241 all adopt a six-tooth structure with uniform circumferential arrangement.

[0033] The length of the horizontal insert 241 is greater than the sum of the tooth thicknesses of tooth structure one 121 and tooth structure two 211.

[0034] The inner width of the latch 12 matches the sum of the thickness of the limiting protrusion 111 and the toothed structure 211.

[0035] When using steam equipment, steam is obtained by connecting to an external pipe through a hose. The parts connected to the hose need to be in a state of relative motion. The installation space for the hose is narrow. When installing the hose in a narrow space, the locking buckle 12 is aligned with the anti-detachment connector 2 and pushed axially. Moreover, the connecting pipe 11 and the connector body 21 have an axial guiding effect. When the locking buckle 12 is pushed to the limit position, the installation can be completed by rotating the locking buckle 12.

[0036] When the equipment is in motion or during installation, the hose 1 can rotate on its own, eliminating the generation of torque. The hose 1 is not subject to torque when it moves with the equipment, thus improving its service life.

[0037] Hose 1 is made of metal hose, hydraulic hose or air hose, and elastic element 23 is made of limit sleeve or snap ring.
