Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hose fastening spring ring used for attaching and fastening a hose to a nozzle or the like, which can be particularly easily fastened and is covered with a heat insulating material after fastening. The present invention relates to a hose fastening spring ring that allows easy attachment of members.

[Conventional technology]

Various hose fastening spring rings are used for attaching and fastening elastic hoses such as rubber hoses and plastic hoses to nozzles and the like.

FIG. 7 is a perspective view of a conventional hose fastening spring ring. In the figure, reference numeral 1 denotes a hose fastening spring ring, which is an annular spring ring body 2 for fastening the hose from the surroundings, a bending piece 3 and a notch portion 4 radially formed at one end of the spring ring body 2.
And a protrusion 5 formed at the other end of the spring ring body 2 so as to be inserted into the notch 4, and a bent piece radially formed at the tip of the protrusion 5.

In the conventional hose fastening spring ring 1 as described above, when the hose is attached to the nozzle or the like and fastened, the bending pieces 3 and 6 are sandwiched by a holding tool such as pliers and the spring ring body 2 is opened to spring the hose. Insert the hose into the ring main body 2 and once attach the hose to the nozzle with the clamp removed, then clamp the bending pieces 3 and 6 again with the clamp and open the spring ring main body 2 and move to the hose mounting position. , The spring ring body 2 by removing the clamp
Tighten the hose mounting position from around.

However, in such a conventional hose fastening spring ring, in order to insert the hose into the spring ring main body 2,
It is necessary to open the spring ring main body 2 by sandwiching the bending pieces 3 and 6 with a sandwiching tool such as pliers. In order to fasten the hose with the spring ring main body 2 after attaching the hose to the nozzle etc., fold it again with the sandwiching tool. Since it is necessary to close the spring ring main body 2 with the bending pieces 3 and 6 interposed therebetween, it is troublesome and it is difficult to work in a narrow space. If the fluid flowing in the hose is hot or cold, it is necessary to install an appropriate heat insulating material in the heat affected area. At that time, the bending pieces 3 and 6 interfere with the heat insulating material, and the heat insulating material is attached. There were problems such as problems.

[Problems to be solved by the device]

The purpose of this device is to solve the above problems.
(EN) It is possible to obtain a hose fastening spring ring which does not require a holding tool at any time, facilitates hose attachment and fastening work in a narrow space, and is not an obstacle after attachment.

[Means for Solving the Problems]

The present invention provides an annular spring ring body for fastening a hose from the surroundings, a first protrusion and a notch formed at one end of the spring ring body, and the spring ring so as to be inserted into the notch. A second protrusion formed on the other end of the main body; a stopper elastically sandwiched between the first protrusion and the second protrusion with the spring ring body open; 1
The engaging recess provided in the stopper so as to engage with the tip of the protrusion and the tip of the second protrusion, and the engaging recess so as to engage with the inside of the first protrusion and the second protrusion. A hose fastening spring ring, comprising: an engagement protrusion provided on a stopper.

[Action]

In the hose fastening spring ring of the present invention, the first projecting portion formed at one end of the spring ring body and the second projecting portion formed at the other end of the spring ring body are in a state where the spring ring body is opened. Since the stopper is elastically clamped, the hose can be inserted into the spring ring main body in this state and attached to the nozzle or the like. At this time, the stopper is provided with an engaging concave portion that can engage with the tips of the first and second protruding portions and an engaging convex portion that engages with the inside of the first and second protruding portions. Therefore, the stopper is elastically sandwiched in a stable state, and the mounting work is easily performed. In this state, when the spring ring body is moved to the mounting portion of the hose and the stopper is removed, the second projecting portion is inserted into the cutout portion, the spring ring body is closed, and the hose is fastened from the surroundings.

[Embodiment] Hereinafter, the present invention will be described with reference to an embodiment of the drawings.

FIG. 1 is a perspective view of a hose fastening spring ring of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a perspective view of a fastening state, FIG. 4 is a front view of a stopper, and FIG. 5 is a plan view thereof. , FIG. 6 is a side view.

The hose fastening spring ring 1 is a hose attached to the nozzle 9 or the like.
An annular spring ring body 2 for fastening 10 from the periphery, a first protrusion 11 and a notch portion 4 formed at one end of the spring ring body 2, and a spring ring so as to be inserted into the notch portion 4. A second protrusion 12 formed on the other end of the main body 2, and a first protrusion 11 and a second protrusion 12 with the spring ring body 2 open.
A stopper 13 elastically sandwiched between the first protrusion
11 and the engaging recesses 14a and 14b provided in the stopper 13 so as to engage with the tip portions of the second protrusion 12 and the insides of the first protrusion 11 and the second protrusion 12 So that the engaging protrusions 15a and 15b provided on the stopper 13 are provided.

The spring ring main body 2 is formed by molding a strip-shaped plate material into a ring shape, and has a notch 4 and a first protrusion 11 at one end thereof.
A second protrusion 12 is formed on the other end. The stopper 13 is formed separately from the spring ring main body 2, and the first
Also, engaging recesses 14a and 14b and engaging protrusions 15a and 15b having shapes corresponding to the shapes of the tips of the second protrusions 11 and 12 are formed. First and second protrusions in the opened state of the spring ring body 2
11 and 12, the tips are inserted into the engaging protrusions 14a and 14b, and the insides of the engaging protrusions 15a and 15b contact and engage with each other, and elastically and stably sandwich the stopper 13. Further, the inner diameter of the spring ring main body 2 in the opened state is larger than the outer diameter of the hose.

In the hose fastening spring ring 1 described above, the spring ring body 2 is opened to the first projecting portion 11 formed at one end of the spring ring body 2 and the second projecting portion 12 formed at the other end. Stopper in the state
