Abstract

The utility model discloses a seal ring for hose coupler, comprising a seal ring body. The outer ring of the seal ring body is provided with a claw, and the diameter which is defined by the axial lead of the claw in the seal ring body is bigger than the inner diameter of a pipe which is to be mounted. The seal ring for hose coupler l has the advantages that the outer ring of the seal ring body is provided with the claw, and the claw is clamped in a special ring groove of the mounting pipe; the claw can be provided with a big size, so that not only the slip out of the seal ring can be avoided, but also the seal ring can be mounted easily. The seal ring for hose coupler has simple structure, convenience and reliability.

Description

The hose coupling seal ring

Technical field

The utility model relates to seal ring, in particular for the seal ring of hose coupling.

Background technique

The flexible pipe Placement of prior art is: with reference to figure 5, Fig. 6, an end that connects the corrugated pipe connector 1 of flexible pipe has step 5, pipe cap 2 is enclosed within on the corrugated pipe connector 1 and can rotates around corrugated pipe connector 1, pipe cap 2 has with the identical screw thread of the pipe joint that need to connect 3, screw thread is generally the pipe pitch thread, pipe cap 2 alignment tube joint 3 and threaded together during installation, at this moment pipe cap 2 docks in pipe cap 2 with pipe joint 3 by step 5 drive corrugated pipe connectors 1, in order to seal, laid seal ring 4 between corrugated pipe connector 1 and pipe joint 3, seal ring 4 is an annular, and external diameter is equal to or slightly less than the aperture of pipe cap internal thread, this kind linkage structure is simple, is adopted widely.But, the hose union of this mode is under the situation of often dismounting, especially manage under the smaller situation of diameter, hose union after the dismounting is in the taking and placing process, seal ring 4 is very easy to eject from pipe cap 2 come off, because seal ring 4 is smaller, usually cause and lose, make troubles for the actual use of hose coupling;

For preventing that seal ring 4 from coming off, also there is thread root to process an annular groove at pipe cap 2, the external diameter of seal ring 4 is slightly larger than the aperture of pipe cap internal thread, seal ring 4 is stuck in mode in the annular groove, but this mode makes seal ring lay up inconvenience, the outer ring of annular groove or seal ring 4 can not be too big, otherwise that seal ring is laid time distortion is just big, unusual effort just when laying.

The model utility content

The purpose of this utility model is: a kind of hose coupling seal ring is provided, solve that above-mentioned prior art exists problem, making seal ring is that difficult drop-off is easy for installation again.

In order to achieve the above object, hose coupling seal ring of the present utility model comprises the seal ring ring body, is provided with hock in the outer rim of seal ring ring body.

The thickness of described hock is less than the thickness of seal ring ring body.

The quantity of described hock is 2-8, and is evenly distributed on the outer rim of seal ring ring body.

The utility model has the advantages that: because hock is established in the outer ring of seal ring ring body, be stuck in hock in the special-purpose annular groove of mounting pipe, the hock external diameter can be done greatlyyer, not only avoid deviating from of seal ring, and it is easy to lay seal ring, simple in structure, very convenient in actual use, reliable.

Embodiment

Referring to accompanying drawing 1-4, hose coupling seal ring of the present utility model comprises seal ring ring body 4, the outer rim of its seal ring ring body 4 is provided with hock 8, the quantity of hock 8 is 6, and is evenly distributed on the outer rim of seal ring ring body 4, and the thickness of hock 8 is less than the thickness of seal ring ring body 4.

Hose coupling seal ring of the present utility model is used as follows in hose union: sleeve cap on the corrugated pipe connector 1, corrugated pipe connector 1 is used for being connected with flexible pipe, pipe cap drives corrugated pipe connector 1 and docks in pipe cap with want mounting pipe 3, pipe cap has interior threaded hole, be used for being connected with want mounting pipe 3, the internal thread root of pipe cap has been processed a special-purpose annular groove 7, seal ring be placed in this annular groove 7 and corrugated pipe connector 1 and between the mounting pipe of wanting 3, hock 8 outer rims are with the internal diameter of the determined diameter in the axle center of seal ring ring body 4 greater than wanted mounting pipe, make seal ring in the special-purpose annular groove of pipe cap, locate and tighten with hock 8, seal ring ring body 4 diameters can be smaller or equal to the internal diameter of the internal thread of pipe cap, only make hock 8 distortion when laying, not only avoid deviating from of seal ring, and it is light to lay seal ring.The thickness of hock 8 makes hock 8 distortion easier less than the thickness of seal ring ring body 4.

Claims

1, a kind of hose coupling seal ring comprises seal ring ring body (4), it is characterized in that: the outer rim at described seal ring ring body (4) is provided with hock (8).
