Abstract
The utility model discloses a connecting joint for a hose and a hard pipe. The connecting joint consists of a joint, a locking nut and a rubber sealing ring. A hose interface end, threads matched withthe locking nut and a hard pipe interface end are arranged on the joint, anti-slip convex teeth are formed at the hose interface end, threads are formed on the inner surface of the hard pipe interface end, and a locking hexagon is arranged on the outer surface of the hard pipe nipple end; threads are formed on the inner surface of one end of the locking nut, a locking hexagon is arranged on the outer surface, and a conical surface matched with the cone angel of the anti-slip convex teeth on the hose interface end of the joint is arranged on the inner surface of the other end; and the rubber sealing ring is laid at an inner-cavity end of the hard pipe interface end. When the structure of the utility model is used to connect with the hard pipe, the joint is directly connected with the hardpipe through the inner threads of the hard pipe interface end; and for the connection of the hose, all that is needed is to insert the hose at the hose interface end of the joint and screw the lockingnut tightly. The connecting joint is characterized by convenient assembly and disassembly, firm connection, good sealing performance, beautiful appearance and simple structure.
Description
Technical field
The utility model relates to a kind of joint, more specifically say so a kind of flexible pipe and hard tube jointing.
Background technique
In daily life, usually can run into the problem that flexible pipe is connected with hard tube.At present common Placement is: hose proof is buried with iron wire or larynx on hard tube tighten.But the problem that exists is that the joint sealing is poor, leaks easily, and when the pressure medium that flows through in the pipe was big, threw off easily the joint, and soundness is poor, and flexible pipe also is easy to damage.
The model utility content
At the problems referred to above, the problem that the utility model quasi-solution is determined has provided a kind of flexible pipe and hard tube jointing, can guarantee the soundness of connection, sealing, easy accessibility, beautiful shape.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of flexible pipe and hard tube jointing, it comprises joint, locking nut, rubber seal.Described joint one end is established the hose connection end, and the joint locking screw is established in the centre, and the other end is established the hard tube interface end, the hose connection end is provided with anti-skidding double wedge, anti-skidding double wedge is provided with screw thread along conical surface arrangement setting separated by a distance in the hard tube interface end, and appearance is provided with fastening six sides.Table is provided with the screw thread that is complementary with the joint locking screw in described locking nut one end, and appearance is provided with fastening six sides, and table is provided with the conical surface that is complementary with the anti-skidding double wedge coning angle of joint in the other end.Described rubber seal lining is in the inner, hard tube interface end chamber.Hard tube is directly by being threaded on the hard tube interface end, by the sealing of lining between inner rubber seal realization joint in hard tube interface end chamber and hard tube during connection.As long as flexible pipe is passed locking nut directly to be enclosed within on the hose connection end, to tighten locking nut then and get final product when connecting flexible pipe, the anti-skidding double wedge that is located on the hose connection end both can play anti-skidding effect, can play the effect of sealing again.
Description of drawings
Fig. 1 is a model utility structure sectional view.
Fig. 2 is that schematic representation is partly cutd open in the decomposition of model utility part.
Fig. 3 is that model utility enforcement flexible pipe is connected sectional view with hard tube
Among the figure: 1-joint, 2-locking nut, 3-rubber seal, 4-screw thread, 5-hose connection end, the anti-skidding double wedge of 6-, 7-screw thread, fastening six sides of 8-, fastening six sides of 9-, 10-flexible pipe, 11-hard tube interface end, 12-screw thread, the 13-conical surface, 14-hard tube.
Specific embodiments
As Fig. 1, Fig. 2, shown in Figure 3, joint 1 left end is provided with hose connection end 5, and the centre is provided with the screw thread 7 that is complementary with locking nut 2, and right-hand member is provided with hard tube interface end 11.Hose connection end 5 is provided with anti-skidding double wedge 6, establishes screw thread 12 in the hard tube interface end 11, and appearance is established fastening six sides 9.Fastening six sides 8 of locking nut one end peripheral hardware, in establish screw thread 4, establish the conical surface 13 that is complementary with anti-skidding double wedge 6 coning angles in the other end.Rubber seal 3 linings are in the inner, hard tube interface end 11 chamber.When connecting flexible pipe, at first flexible pipe 10 is passed locking nut 2, be enclosed within on the hose connection end 5, be enclosed within on fastening six sides 9 with a spanner then, another spanner is enclosed within on fastening six sides 8, tighten locking nut 2, owing to the coning angle of the conical surface 13 with anti-skidding double wedge 6 is complementary, along with tightening of locking nut 2, flexible pipe 10 contacts with the conical surface 13, anti-skidding double wedge 6 makes flexible pipe 10 depressions, makes flexible pipe 10 and anti-skidding double wedge 6 that good sealing be arranged, and is connected firmly.When connecting hard tube, as long as hard tube 14 directly is connected with the hard tube interface end 11 of joint 1 by screw thread 12, by the lining sealing that inner rubber seal 3 realizes between joint 1 and the hard tube 14 in hard tube interface end 11 chambeies.
