Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the structure of attaching a hose fitting used for piping a hose. The mounting structure of the present invention is, for example, when attaching an automobile brake hose to a vehicle body.
Installation of intermediate holding parts to prevent loosening and contact with other parts can be used in the structure.

[Prior Art 1] Conventionally, as a device for holding the intermediate portion of a hose, a device using a pair of male and female metal fittings that can be screwed together is known. However, this metal fitting has a large number of component parts and is expensive in terms of cost.

Therefore, Japanese Utility Model Publication No. 59-6310 discloses an intermediate holding part that includes a flange, an engaging part, and a cylindrical part.

In this intermediate holding part, the cylindrical part is inserted into a through hole provided in a bracket extending from the vehicle body, etc., and after being locked with the flange and positioned, the spring clip is held between the locking part, and the spring clip and flange are connected. The bracket is clamped and fixed by the brackets. Although this intermediate holding part can solve the above problems, it is difficult to work in a narrow work space by inserting the intermediate holding part with a hose fixed to the through hole of the bracket. There is a problem.

Therefore, the actual installation is as follows:
The mounting structure as seen in the 8690 publication is frequently used. As shown in FIG. 6, this installation consists of a cylindrical sleeve 101 through which the hose 400 is inserted, and a plate-shaped flange 102 that protrudes radially from the outer peripheral surface of the sleeve 101.
A hose fitting 100 is provided with a hose fitting 100, a plate-shaped bracket 200 extends from the attached part, a bolt 300 and a nut 301, and the bracket 200 and the flange part 10
2 are overlapped and fixed with a bolt 300 and a nut 301 via a washer 500.

This mounting structure has excellent workability in narrow work spaces.

[Problems to be Solved by the Invention] For example, brake hoses of automobiles are piped to the vehicle body in a state where they are exposed to the outside. As a result, icing may form on the brake hose during winter. When icing occurs in this manner, an overload is applied to the fixed portion of the hose fitting due to the weight of the adhered ice.

By the way, in the structure of the attachment of the hose fitting disclosed in the above-mentioned Japanese Utility Model Publication No. 60-178690, stress due to the above-mentioned overload acts concentratedly on the fixed portion between the flange 102 and the bracket 200.

In particular, when an overload is applied in the direction shown in FIG.
There is a strong possibility that deformation will occur in 2. Although such problems can be prevented by increasing the material strength of the flange 102, this is not preferable because it increases weight and cost.

In addition, in the structure of the conventional hose fitting, the flange 102
It is relatively easy to rotate the bolt 300 along the surface of the bracket 200 (in the direction perpendicular to the plane of FIG. 6). Therefore, the positioning accuracy during installation is poor, and mistakes may occur during installation. Also, during use, it may gradually move due to vibration or the like.

The present invention solves these problems, and the installation disclosed in Utility Model Application Publication No. 60-17A69O improves the structure, maintains the same workability in a narrow work space, and reduces weight and cost. The attachment of the hose fitting provides a structure that can prevent an increase in the amount of water and prevent deformation of the hose fitting.

[Means for Solving the FIR Problem] The hose fitting installation structure of the present invention includes a cylindrical sleeve into which the hose is inserted, and a plate-shaped flange projecting in the radial direction from the outer peripheral surface of the sleeve. It consists of a hose fitting, a plate-shaped bracket extending from the attached part, a washer, and fixing members such as bolts and nuts, and a flange part.
The hose fitting is attached to the bracket by stacking the bracket and washer and fixing them with a fixing member.The structure of the hose fitting is that the washer has a flange that protrudes toward the bracket and extends beyond the side of the flange and bracket. The sleeve is characterized in that a gripping portion extending around the opposite surface is provided so as to prevent the hose fitting from moving relative to the bracket in the axial direction of the sleeve.

The mounting structure of the hose fitting of the present invention is composed of a hose fitting, a bracket, a washer, and a fixing member.

Among them, the hose fitting consists of a sleeve and a flange. A hose is inserted into the sleeve and fixed by caulking, gluing, etc. It is also possible to insert an inner tube into the hose and clamp and fix the hose between the inner tube and the sleeve. This inner tube may be formed separately from the hose fitting, or may be formed integrally with the hose fitting. Further, the sleeve may be provided only on one side of the collar, or may be provided on both sides of the collar. Further, the number of the flange portions may be one or a plurality of flange portions.

As the fixing member, various conventionally known fixing means can be used, such as one using bolts and nuts, and one gripping with a clamp or the like.

The greatest feature of the present invention lies in the structure of the washer.

That is, the washer used in the mounting structure of the present invention is provided with a protruding grip portion that protrudes toward the flange and the bracket and extends beyond the side surface of the flange and the bracket to the opposite surface. The gripping portion is configured to restrict relative movement of the hose fitting with respect to the bracket in the axial direction of the sleeve.

This washer may be placed in contact with the bracket or may be placed in contact with the flange. Further, the number of gripping parts is not particularly limited.

In addition, it is desirable that the washer is provided with a locking portion having a locking surface substantially parallel to a plane including the fixing point of the fixing member and the axis of the sleeve, in addition to the gripping portion.

In this way, the locking portion can restrict movement of the hose fitting in the direction along the bracket surface. This locking portion can also serve as the gripping portion by using the inner circumferential surface of the gripping portion as a locking portion, or may be formed separately from the gripping portion.

[Operations and Effects of the Invention] The structure of the hose fitting of the present invention is such that the washer has a gripping portion that protrudes toward the flange and the bracket and extends beyond the flange and the side of the bracket to the opposite surface. The grip portion restricts the hose fitting from moving relative to the bracket in the axial direction of the sleeve. Therefore, according to the structure, the installation of the hose fitting of the present invention is as follows:
When an overload is applied due to icing, etc., the stress also acts on the gripping portion, so that the stress can be distributed and applied to the hose fitting. This can prevent deformation of the hose fitting. Furthermore, since only the gripping portion is provided, increases in weight and cost can be minimized. The mounting structure of the present invention can be improved by simply replacing the washer while leaving the hose fittings and brackets as they are in the past. Therefore, resources and man-hours can be saved. Furthermore, the hose fittings can be easily installed in the same way as conventional hose fittings, and workability in narrow work spaces is also excellent.

[Examples] Hereinafter, the present invention will be explained in more detail with reference to a plurality of Examples. It should be noted that similar parts and parts having similar functions will be described with the same numbers as those in the appealed embodiment for convenience.

Embodiment 1 FIGS. 1 and 2 show the structure of a hose fitting according to a first embodiment of the present invention. The structure of this installation consists of a hose fitting 1 consisting of a cylindrical sleeve 10 into which the hose 5 is inserted, a plate-shaped collar 11 that protrudes radially from the outer peripheral surface of the sleeve 10, and a part to which the hose 5 is attached, such as a vehicle body. It is composed of a plate-shaped bracket 2- which is extended, a fixing member 3 consisting of a bolt 30 and a nut 31, and a washer 4 arranged so as to be in contact with the flange 11.

In the hose fitting 1, the sleeve 10 and the collar portion 11 are integrally connected, and the hose 5 is fixed to the hose fitting 1 by caulking the sleeve 10 from the outer periphery. Further, the flange portion 11 is provided with a bolt hole through which a bolt 30 is inserted.

The bracket 2 has a long plate shape, and has bolt holes drilled therein like the flange 11.

Washer p4 has a bolt hole, bracket 2 and flange 1.
Two 1-shaped gripping portions 40 are formed that protrude and extend toward one side, go beyond the flange portion 11 and the side surface of the bracket 2, and wrap around the opposite surface of the bracket 2.

In each component configured as described above, first, the hose 5 is pushed through the hose fitting 1, and the sleeve 10 is caulked from the outer periphery, thereby fixing the hose 5 and the hose fitting 1. Next, the bracket 2, the flange 11, and the washer 4 are stacked in this order and fixed with bolts 30 and nuts 31 so that the grip 40 grips the flange 11 and bracket 2.

In the mounting structure of this embodiment, the grip part 40 is attached to the bracket 2.
It wraps around the opposite surface of the flange 11 and grips the bracket 2. Therefore, the hose 5 is exposed to excess M in the direction of B in FIG.
Even if ffl is applied, the stress is received by the contact surface between the grip part 40 and the bracket 2, and the movement of the collar part 11 in the axial direction is restricted by the washer 4. This prevents concentration of stress and deformation of the flange 11.

Note that it is also preferable that the width of the inner circumferential surfaces of the two gripping parts 40 facing each other be substantially the same as the width of the bracket 2. In this way, the inner circumferential surface of the grip portion 40 acts as a locking surface. That is, when connecting the hose fitting 1 and the bracket 2, the sleeve 10 is attached to the grip part 4.
It is installed guided by the locking surface of 0. Therefore hose 5
Also, the hose fitting 1 can be positioned easily and reliably. Furthermore, even if the fixing part of the fixing member 3 becomes loose due to vibration or the like during use, the movement of the hose fitting 1 along the surface of the bracket 2 is restricted by the locking surface, and problems such as displacement of the position of the boss 5 can be prevented.

(Example 2) In the third example shown in FIG. 3, the mounting of Example 1 is a modification of the structure, and the sleeve 10 is
This is the same as in the first embodiment except that a kerf 23 having a width approximately equal to the outer diameter of is provided.

In this embodiment, the sleeve 1o is fixed in the cut groove 23 and the inner circumferential surface in contact with the sleeve 10 acts as the locking surface 21.

That is, in the mounting structure of this embodiment, the hose fitting 1 is restricted from moving in the axial direction by the gripping part 40, and
The locking surface 21 of the bracket 2 restricts rotational movement along the surface of the bracket 2 about the bolt 30.

(Example 3) In the third example shown in FIG. 4, the washer 4 is
It has two gripping parts 40 as well as the sleeve 1.
A kerf 41 having a width approximately equal to the outer diameter of 0 is formed. Regarding the mounting structure of this embodiment, the grip part 40 functions in the same manner as in the first embodiment, and the rotational movement of the hose fitting 1 along the surface of the bracket 2 is caused by the sleeve 10 locking the inner peripheral surface of the cut groove 41. In addition to contacting the surface, the holding portion 40 is regulated by contacting the side surface of the bracket 2.

(Embodiment 4) FIG. 5 shows the installation structure of the fourth embodiment. Regarding the mounting structure of this embodiment, the bracket 2 has a cut groove 23 as in the second embodiment, and the washer 4 is provided with only one grip portion 40.

In the above embodiments, the hose fitting is an intermediate holding part, but the present invention is not limited to this. It can be applied to intermediate holding parts, etc. Furthermore, the material of each component, the presence or absence of an inner tube within the hose, etc. are not particularly limited.
