Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hose connection reinforcing member. More specifically, the present invention relates to an improvement in the structure related to the ease of handling of a connection reinforcing member that increases the connection strength when connecting a hose to a connection end of a connection part.

[Prior Art] Conventionally, a caulking tube shown in FIG. 6, for example, is known as a connection reinforcing member for a hose.

This conventional hose connection reinforcing member is made of a deformable metal material and has a cylindrical overall shape.
A mounting hole 2 having a stopper 1 is opened at one end thereof, and an insertion hole 3 is opened at the other end.

This conventional hose connection reinforcing member is externally attached to the connection end B formed on the connection part A, and when the connection end B is attached to the connection part A, the connection end B is attached to the attachment hole 2. It can be installed in advance by inserting the end B through the side and using the stopper 1 to prevent it from coming off, or it can be installed by fitting the attachment hole 2 from the opposite side of the connecting end B to the side to be assembled when the hose C is connected. When connecting the hose C, insert the hose C between the insertion hole 3 and the connection end B, push it in until it reaches the stopper 1, and use a caulking jig or the like from approximately the center of the outside of the circumferential surface 4. The crimping is used to press and fix the hose C to the connection end B at the crimped deformed portion 5.

[Problem to be solved by the invention] In the conventional hose connection reinforcing member described above, when the hose C is inserted, the degree of insertion cannot be visually confirmed from the outside. It was crimped before reaching 1,
This has the problem of causing connection failures such as water leakage and disconnection.

Further, even if the hose C is inserted securely so as to reach the stopper 1, the same problem will occur if the caulking is not performed at an accurate position (substantially at the center of the circumferential surface 4).

In addition, to solve the problem of the hose C being pinched, fit a cylindrical tube with a diameter larger than the outside diameter of the hose C, and connect the hose to the connection end B. It is conceivable to swage the hose C by moving it to the outside of the hose C after it has been fitted, but since the diameter is formed with a margin, the range of deformation of the swage deformation portion 5 due to swage becomes large. This still has the problem of poor connection.

The present invention was devised to solve these problems, and its purpose is to provide a hose connection reinforcing member that can reliably insert the hose. In addition, it is an object of the present invention to provide a hose connection reinforcing member that can be caulked at an accurate position.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the hose connection reinforcing member according to the present invention employs the following means.

That is, in claim 1, the hose is wrapped around the connection end so that the hose can be inserted between the connection end formed in the connection part, and the hose that has been crimped and inserted is pressed and fixed to the connection end. This means is characterized in that in a cylindrical hose connection member, at least one through hole is formed near one end of the cylindrical circumferential surface.

According to a second aspect of the present invention, in the hose connection reinforcing member of the first aspect, an indication indicating a caulking position is provided on the circumferential surface of the cylinder.

[Function] According to the above-mentioned means, in claim 1, it is possible to visually check whether or not the hose has been inserted reliably through the through hole, so that the hose can be reliably inserted. The purpose of doing so is achieved.

Furthermore, in addition to the above-mentioned effect, claim 2 achieves the objective of making it possible to sew at an accurate position because staking can be performed without erroneous positioning according to the instructions on the display. be done.

[Example] Hereinafter, an example of the hose connection reinforcing member according to the present invention will be described with reference to FIGS. 1 to 5.

1 to 3 show a first embodiment of a hose connection reinforcing member according to the present invention, which corresponds to claim 1.

In this embodiment, the basic structure is the same as that of the conventional example, and a through hole consisting of a small round hole is formed at an interval of 180 degrees near the end of the peripheral surface 4 on the mounting hole 2 side. It is characterized by having two 6-hole holes.

In addition, to explain in detail the surrounding members other than this, the connection part A is a nipple-shaped water divider, the connection end B is a multi-stage cylindrical so-called bamboo shoot, and the hose C is a synthetic resin extrusion molded product. .

According to such an embodiment, as shown in FIG. 3A, the through hole 6 is placed on the side of the connection part A, and the attachment hole 2 is fitted into the connection end B for exterior mounting, and the hose is attached as shown in FIG. 3B. Insert C between the insertion hole 3 and the connection end B,
The hose C is pushed in until it is visible through the through hole 6, and then caulked as shown in FIG.

In other words, the fact that the inserted hose C is visible through the through hole 6 means that the hose C has been securely inserted until it reaches the stopper 1, and as a result, even if it is crimped, the connection will not occur. It will not become defective.

In addition, since the through-hole 6 is used to visually recognize the inserted hose C, the shape thereof, such as a square hole or a slit, may be arbitrary, and the number thereof may also be arbitrary.

However, as mentioned above, making the through hole 6 a small round hole has the advantage of saving the opening area and not reducing the strength of the member. Having individual openings has the advantage of being visible from any angle.

FIG. 4 shows a second embodiment of the hose connection reinforcing member according to the present invention, which corresponds to claim 2.

In this embodiment, in addition to the configuration of the first embodiment,
An indication 7 consisting of two lines indicating both sides of the caulking position is provided on the circumferential surface 4.

This indication 7 can be written by any means such as printing, engraving, perforation, bending, etc.

According to this embodiment, by performing crimping by abutting a crimping tool between the indicia 7, the crimping position is not mistaken and connection failure is prevented.

FIG. 5 shows a third embodiment of the hose connection reinforcing member according to the present invention, which corresponds to claim 2.

In this embodiment, the display 7 of the second embodiment is used as a point indicating the center of the caulking position.

According to this embodiment, in addition to achieving the same effects as the second embodiment described above, the peripheral surface 4 is different from the second embodiment.
This has the advantage of being simplified.

In addition to the illustrated embodiment, a simple cylindrical embodiment without the stopper 1 is also possible.

[Effects of the invention] As described above, the hose connection reinforcing member according to the present invention, as common to claims 1 and 2, can securely insert the hose, or in addition, can caulk at an accurate position. Since this can be carried out in the same way, it is possible to reliably connect and reinforce the hose without causing connection failures. Furthermore, this effect improves the durability and pressure resistance of the connecting portion of the hose, thereby increasing the versatility of the hose and the like.

Furthermore, as common to claims 1 and 2, since the structure is simple, it can be manufactured at low cost and easily,
Since the basic structure is substantially the same as that of the conventional example, there is an advantage that existing products can be easily modified.

Furthermore, as only claim 2, since the crimping position is indicated, there is an effect that the crimping operation is facilitated.
