Description

[Detailed description of the invention] (Field of industrial application) This invention is a hose stopper that is used to clamp the hose from the outside and fix it to the connecting pipe without pulling it out when inserting and connecting the hose into the connecting pipe. It's about the ingredients.

(Prior Art) As a conventional general hose stopper used for such purposes, there is one shown in FIG. 6 or 7. The one in Fig. 6 is a metal strip 1 curved into a ring shape, and small pieces 2 formed at both ends with a width approximately half that of the strip 1.
are arranged in parallel, the tips of both small pieces 2 are bent outward, and a resin operating knob 3 is fixed thereto. By applying pressure to both knobs 3 with fingers in the directions of the arrows, the diameter of the band 1 is expanded, and the hose is inserted through this. In addition, the one in FIG. 7 also has a metal strip 4 curved into a ring shape,
The difference from the one in FIG. 6 is that a small piece 5 protruding from the center of one end of the band 4 is loosely inserted between a pair of small pieces 6, 6 formed at the other end of the band 4, and each small piece 5, 6
The protruding piece 7 is formed by bending the distal end thereof outward.

(Problems to be Solved by the Invention) In each of the hose stops described above, the tabs 1 and 4 are inserted into the hose in a state in which the tabs 1 and 4 are expanded in diameter by pressurizing the knob 3 or the protrusion 7 in the approaching direction. After inserting this hose into the connecting pipe, the stopper is expanded in diameter again and moved to the connecting part of the hose with the connecting pipe, and the pressure on the knob 3 or the protrusion 7 is released.
The strips 1 and 4 clamp the hose to the connecting pipe with their restoring force. When expanding the diameter of the belt-shaped bodies 1 and 4, the sixth
The one shown in the figure has a relatively large knob 3 and can be operated with fingers without using any tools. However, since it has a large knob 3, it is not suitable for tightening a hose in a place where there is almost no extra space, such as the engine room of an automobile.

On the other hand, the one in Figure 7 has a small operating protrusion 7, so it is suitable for use in places with little space, such as the engine compartment of a car.
Because the protrusion 7 is small, it is necessary to pinch it using tools such as pliers and move the stopper to the connecting part of the hose to the connecting pipe while holding it in an expanded state, which is extremely difficult. It requires a lot of work and is inefficient.

(Purpose of the invention) The present invention was made in order to solve the problems of the conventional technology.The projecting part for diameter expansion operation was made as small as possible, and the diameter expansion state was maintained. It is an object of the present invention to provide a hose stopper that can be handled in a flexible manner and that can be released from an enlarged diameter state with a simple means.

(Means for Solving the Problems) In order to achieve the above object, the hose stopper of the present invention is curved into a cylindrical shape with an inner diameter slightly smaller than the outer diameter of the hose that is to hold the elastic strip. At the same time, the small pieces provided at both ends of this band-like body are made parallel to each other so that the diameter can be expanded, and claw portions that engage with each other in the expanded diameter state are formed on each opposing side surface of the two small pieces. The gist is that a gap is provided between the two small pieces on at least one side of both the claw parts in the mated state, and the tips of the two small pieces are bent slightly outward to form protruding pieces. .

(Function) With the above configuration, when the diameter of the band-shaped body is expanded in advance and both claw portions are engaged with each other, the expanded diameter state is maintained.

In this state, the hose is inserted without applying any force and moved to the connection part of the hose with the connecting pipe. When some tool is pressed into the gap between each of the small pieces close to both claws, both small pieces are pushed in the direction of separating from each other, the engagement between both claws is released, and the band-like body tightens the hose with its restoring force. Clamp it in the connecting pipe.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figures 1 to 5 show an embodiment of the hose stopper of the present invention, and Figures 1 to 3 are a perspective view, a plan view, and a front view, respectively, in a tightened state.
FIGS. 4 and 5 are a perspective view and a plan view in the expanded diameter state. In these figures, reference numeral 10 denotes a cylindrically curved band-shaped body, which has an inner diameter slightly smaller than the outer diameter of a hose 12 to be connected to a connecting pipe 11. Small pieces 13 and 14 are formed at both end portions of the band-like body 10, and are parallel to each other and are located on opposite sides with approximately half the width of the band-like body 10, and the tip portions of these small pieces 13 and 14 are Projecting pieces 15 and 16 are formed that are slightly bent outward. Claw portions 17 and 18 that engage with each other in the expanded diameter state are formed on opposing side surfaces of both the small pieces 13 and 14, respectively, as shown in FIGS. 4 and 5, and as shown in FIG. A gap 19 is provided between the small pieces 13 and 14 on one side of the claws 17 and 18 in the engaged state. In addition, each protruding piece 15,1
A space is also provided in the front part of each of the parts 6 and 6.

Next, the operation of the above embodiment will be explained.
First, before use, force is applied to both protrusions 15 and 16 in a direction in which they approach each other to expand the diameter of band-shaped body 10 and to engage both claws 17 and 18. Both claws 17, 1 are pulled together by the restoring force of the elastic band 10.
8 come into pressure contact with each other and reliably maintain the expanded diameter state.
The hose 12 is inserted through the belt-shaped body 10 in an expanded diameter state, the connecting pipe 11 is inserted into the opening of the hose 12, the hose 12 is connected to the connecting pipe 11, and the stopper is then moved to the connecting pipe 11 side. let This work is carried out because the belt-shaped body 10 maintains its expanded diameter state.
This can be done very easily and quickly without using any tools or requiring any force.

Once the stopper is set at a predetermined position on the hose 12, a tool such as a flathead screwdriver is pressed into the gap 19. As a result, a force acts in the direction of separating the small pieces 13 and 14 from each other, and when the engagement between the claws 17 and 18 is released, the restoring force of the band 10 reduces the diameter, that is, returns to the original state. and strip 1
0 tightens the hose 12 and clamps it to the connecting pipe 11, and the hose 12 is connected to the connecting pipe 11 without coming off.

When the claws 17 and 18 are disengaged, the tips of the small pieces 13 and 14 are bent outward to form the projecting pieces 15 and 18.
16, the tips of the small pieces 13 and 14 smoothly slide onto the hose 12 without biting into the hose 12, and the hose 12 is not damaged. Further, when the hose 12 is replaced due to deterioration over time, the diameter of the hose 12 can be expanded using both protrusions 15 and 16, and the hose 12 can be easily removed.

It should be noted that the present invention is not limited to the embodiments described above, and it goes without saying that various embodiments can be considered without departing from the scope of the claims. For example, the material is not limited to metal, and may be molded from synthetic resin.
Further, in the embodiment, both the claw portions 17 and 18 are connected only between the small pieces 13 and 14 on one side of the claw portions 17 and 18 in the engaged state.
18, a gap 19 for the disengagement operation was formed,
It goes without saying that gaps may be provided on both sides.

(Effects of the invention) As detailed above, according to the hose stopper of the invention, a pair of claws that engage with each other in the expanded diameter state;
The structure has a gap for disengaging the claws, and a protruding piece with the tips of both small pieces bent slightly outward, so it can be easily removed without the use of a tool or force when the diameter is expanded in advance. The hose can be inserted and set in a predetermined position without adding any additional pressure, making the work extremely easy and quick. In addition, since the protruding piece is only used when expanding the diameter before inserting the hose and when exchanging the hose, it can be as small as possible and only protrude slightly. Since the hose can be set without using any tools, it can be applied to connect hoses in places where space is severely restricted, such as in automobiles, to achieve remarkable effects.
