Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hose joint that can connect hoses with one touch.

Various types of such hose fittings have been conventionally provided.

Such a known hose joint includes a socket, a spigot that is detachably inserted into the socket, and when the spigot is inserted into the socket, it engages with the engaging part of the spigot to prevent the spigot from coming out. It is composed of a retaining member to prevent the retainer from coming off, and a sliding tube that is fitted to the outside of the receptacle so as to be able to move forward and backward, and the retaining member and the spigot are disengaged by moving the sliding tube. Most of them.

In such known hose joints, the problem is the retaining member.

A ball is used as this retaining member,
It is broadly divided into those using rubber.

Many ball-based tools use steel balls due to their strength, and when steel balls are used, the socket and spigot are often made of metal due to the relationship between strength and hardness.
Additionally, problems arise with the means for holding the steel balls so that they do not fall off.

Also, if rubber is used as the retaining member, there is no problem even if the socket and spigot are made of plastic.
Since the retaining member is elastically deformed, there is a problem in ensuring that it functions reliably.

In view of the above-mentioned problems with conventional hose joints, it is an object of the present invention to provide a hose joint that is securely secured during connection so that there is no risk of it coming off, and that can be easily separated. It is.

In other words, the present invention provides a hose joint having a known configuration as described above, in which a retaining member is fitted into a recess on the outside of a retaining opening provided in a socket, and a main body part that fits into a recess on the outside of a retaining opening provided in a socket; The rear end of the claw protrudes from the retaining opening into the socket and engages with the outer engaging part of the spout inserted into the socket. The rear end of the main body of the retaining member is provided with a shaft portion that rotatably fits into the recess on the outer periphery of the socket, so that the retaining member can swing inward and outward directions around this shaft portion. The sliding tube is pushed forward by a spring, and a pressing surface on the inner periphery of the sliding tube that pushes the retaining member inward when the sliding tube is located forward;
A recess is provided in which the retaining member escapes outward when the sliding tube compresses the spring and retreats rearward.

Since this invention has the above structure, when inserting the spout into the receptacle, the claw portion of the retaining member protruding diagonally rearward from the retaining opening of the socket is pushed into the retaining opening by the outer periphery of the receptacle. This makes it extremely easy to insert the spout.

In addition, when the spout is inserted in this way, the claw part engages with the recessed engagement part on the outside of the spout to prevent it from coming out, and at this time, even if a force is applied to the spout in the direction of pulling it out, Since the outer side of the main body of the retaining member is pressed by the inner circumferential surface of the sliding tube and cannot escape outward, the retaining effect is reliable.

Furthermore, when removing the spout, the outer sliding tube is moved back against the elasticity of the spring, so that the recess of the sliding tube is located outside the main body of the retaining member, and the inner circumferential surface The retainer is released and the retaining member can rotate outward about the shaft at the rear end, making it possible to easily pull out the spigot.

An embodiment of the hose joint of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a socket, 2 is a spigot, and 3 is a sliding tube.

A screw tube 4 is integrally fixed to the rear of the socket 1, and the end of a hose 6 is fitted into a connecting tube 5 at the rear end of the screw tube 4 and fixed with a hose lock nut 7.

A threaded tube 8 and a hose connection tube 9 are also provided at the rear end of the spout 2, and the end of the hose 10 is fitted into the end of the connection tube 9 and fixed with a hose lock nut 11.
However, either the socket 1 or the spigot 2 may be configured to communicate directly with the water faucet.

Reference numeral 14 denotes a retaining member made of an elastic material such as semi-hard rubber, which consists of a main body part 15 and a claw part 16 that engages with the engaging part 12 of the spout 2. A shaft part 17 is integrally provided at the rear part of the member. Both ends protrude from both sides of the main body portion 15.

The socket 1 is provided with a plurality of retaining openings 18, and recesses 19, 20 are formed at the front and rear of the outside of the openings 18.
The front and rear parts of the main body part 15 are fitted into the socket, and the claw part 16 is made to protrude into the socket 1 through the opening 18.

Further, a pair of left and right ribs 21 are provided on both sides of the opening 18 on the outside of the socket 1 as shown in FIGS. Engage as shown in Figure 4.

The inner circumferential surface 22 of the intermediate portion of the sliding tube 3 is provided with ribs 21.
The lower part is a large-diameter inner circumferential surface, and between the upper step 24 and the step 25 at the rear of the outer periphery of the socket 1, there is a coiled spring that pushes the sliding tube 3 forward. Put on 26.

The sliding tube 3 is also made of a semi-hard elastic material, and a plurality of locking pawls 27 are provided diagonally forward on the front side of the inner peripheral surface thereof as shown in FIG.
is provided on the outside of the end of the socket 1 to prevent the sliding tube 3 from coming off.

Reference numeral 29 in FIG. 1 denotes a rubber gasket fitted on the rear inner circumference of the socket 1, which tightly contacts the outer periphery of the tip of the spout 2 inserted into the socket 1 to prevent leakage between the socket 1 and the spout 2.

In the above configuration, as shown in FIG.
When the spigot 2 is inserted into the socket 1 while the locking claw 27 is moving forward until it touches the locking part 28 of the socket 1, the outer periphery of the spigot 2 touches the claw part 1 of the retaining member 14.
6 deeply enters into the socket 1 while pushing it inward, the claw part 16 engages with the engaging part 12, and the outer periphery of the inner end of the spigot 2 comes into close contact with the inner periphery of the gasket 29.

In this state, a downward force is applied to the hose 6, an upward force is applied to the hose 10, and the spigot 2
When the spigot 1 tries to come out of the socket 1, the claw part 16 engages with the engaging part 12 of the spigot 2, as shown in FIG. 1, and prevents the spigot 2 from coming out.

In the above case, the back part of the claw part 16 is supported by the inclined surface a of the opening 18, and the claw part 16 is made of a semi-hard material that does not deform, so that it can sufficiently withstand even a large extraction force. Can be done.

Furthermore, when the pull-out force is applied, the pull-out prevention member 14 tries to rotate outward around the shaft 17, but the member 1
The outer side of the main body part 15 of 4 is received by the inner circumferential surface 22 of the sliding tube 3 to prevent it from rotating outward, and even if the retaining member 14 tries to move outward together with the spigot 2, The engagement between the front end of the main body part 15 and the recess 19 and the engagement between the shaft part 17 and the rib 21 prevents it from moving forward, so that the effect of preventing it from coming off is perfect.

Next, when the sliding tube 3 is moved back against the spring 26 to the position shown in FIG.

In this state, when the socket 1 and the spigot 2 are pulled in opposite directions as shown by the arrows in FIG. Rotates outward around the shaft portion 17. Therefore, the spigot 2 can be easily removed from the socket 1.
