Abstract

PURPOSE:To prevent a hose fitting from being deformed, by forming a projecting grip part on at least one of a flange part and a bracket. CONSTITUTION:Two L-like grip parts 20 are formed on one end part of a bracket 2, extending on both sides of a flange part 11 from both sides of the bracket 2 beyond the side surfaces of the flange part 11, and being bent toward the outer surface of the flange part 11 remote from the surface thereof making contact with the bracket 2. With this arrangement, in the case of overload due to ice accretion, the stress acts also upon the grip parts 20 so as to be distributed in part to a hose fitting 1, and accordingly it is possible to prevent the hose fitting from being deformed. Further it is possible to facilitate the attachment of the hose fitting 1, thereby it is possible to make the workability satisfactory even in a narrow working space.

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] 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 7 langes and positioned, the spring clip is sandwiched between the engaging part, and the spring clip and 7 The bracket is clamped and fixed by the lunge. 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. 10, this installation consists of a cylindrical sleeve 101 into which the hose 400 is inserted, and a plate-shaped collar 10 that protrudes radially from the outer peripheral surface of the sleeve 101.
2, a plate-shaped bracket 200 extending from the part to be attached, a bolt 300 and a nut 301, and the bracket 200 and the flange part 1
02 are overlapped and fixed with bolts 300 and nuts 301. 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 of the plane of the paper in FIG.
There is a great possibility that deformation will occur in the second part. Although such problems can be prevented by increasing the strength of the material 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. 10). 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 mounting disclosed in Japanese Utility Model Application Publication No. 60-178690 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.

[, i! Means for Solving the Problem] The structure of the hose fitting of the present invention is that the hose fitting includes a cylindrical sleeve through which the hose is inserted, and a plate-shaped flange projecting in the radial direction from the outer peripheral surface of the sleeve. The object to be attached consists of a plate-shaped bracket extending from the part, and fixing members such as bolts and nuts.By overlapping the collar and the bracket and fixing them with the fixing member, the hose fitting can be attached to the bracket. The structure of the hose fitting is such that at least one of the collar and the bracket has a gripping part that protrudes to the other side and goes over the other side and wraps around the opposite surface. is configured to restrict relative movement of the sleeve in the axial direction with respect to the bracket.

The mounting structure of the hose fitting of the present invention is composed of a hose fitting, a bracket, 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. Also insert the inner tube into the hose,
It is also possible to clamp and fix the hose between the inner pipe 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 most important feature of the present invention is that at least one of the bracket and the collar has a gripping part. This grip protrudes toward the other member of the flange and bracket, and wraps around the side of the other member to the opposite surface, thereby allowing the hose fitting to move relative to the bracket in the axial direction of the sleeve. If the configuration regulates
Its shape is not particularly limited. As shown in the examples described below, for example, it may be protruded from the bracket and gripped from one or both sides of the flange, or it may be protruded from the flange and gripped from one or both sides of the bracket. Can be done. Moreover, it can also be provided on both the bracket and the flange.

Note that it is desirable that one of the hose fitting and the bracket be provided with a locking portion that abuts the other and has a locking surface that is substantially parallel to a plane that includes the fixing point of the fixing member and the axis of the sleeve. 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 surface, 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 at least one of the collar and the bracket has a gripping portion that protrudes toward the other side and extends over the other side and wraps around the opposite surface. The gripping portion restricts relative movement of the hose fitting in the axial direction of the sleeve with respect to the bracket. Therefore, according to the structure of the hose fitting of the present invention, it is difficult to prevent overheating due to icing etc. When a load is applied, the stress also acts on the gripping part, so the stress can be distributed and applied to the hose fitting.This prevents deformation of the hose fitting.Also, when the gripping part is Since the hose fittings are simply installed, weight and cost increases can be kept to a minimum.Furthermore, the hose fittings can be easily installed in the same way as conventional hose fittings, and workability in narrow working spaces is also excellent.

[Examples] Hereinafter, the present invention will be briefly and specifically explained using a plurality of Examples. For convenience, similar parts and parts having similar functions will be described with the same numbers in each embodiment.

(Embodiment 1) FIGS. 1 and 2 show the structure of mounting 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 4 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 4 is attached, such as a vehicle body. A plate-shaped bracket 2 extended further, a bolt 30, a nut 31, and a washer 3
and a fixing member 3 consisting of two parts.

In the hose fitting 1, the sleeve 10 and the collar portion 11 are integrally connected, and the hose 4 is fixed to the hose fitting 1 by caulking the sleeve 10 from the outer periphery. Further, the flange 11 has a bolt hole 12 into which the bolt 30 is inserted.
is drilled.

At the end of the bracket 2, there are 2 grooves that protrude and extend from the side surfaces of the bracket 2 to both sides of the flange 11, and that extend beyond the lateral sides of the flange 11 and wrap around the surface of the flange 11 opposite to the surface in contact with the bracket 2. Two L-shaped grip portions 20 are formed. The space surrounded by the grip part 20 and the bracket 2 has a width equal to the width of the flange part 11 and the space between the brackets 2 and 2.
The inner circumferential surface in contact with the side surface constitutes the locking surface 21. That is, the grip portion 20 also serves as a locking portion. Further, the bracket 2 has a bolt hole 22 formed above the grip portion 20 into which a bolt 30 is inserted.

In each component configured as described above, the hose 4 is first inserted into the hose fitting 1, and the sleeve 10 is caulked from the outer periphery, thereby fixing the hose 4 and the hose fitting 1. Next, the flange 11 is inserted into the space surrounded by the grip 20 and the bracket 2, and the flange 11 and the bracket 2 are overlapped so that the two bolt holes 12 and 22 communicate with each other, and the washer 32 is inserted between the flange 11 and the bracket 2. Fix with bolts 30 and nuts 31.

In the mounting structure of this embodiment, the grip part 20 wraps around the surface of the flange part 11 on the side opposite to the bracket 2 and grips the flange part 20. Therefore, even if an overload is applied to the hose 4 in the direction B in FIG. 2, the axial movement of the collar portion 11 is restricted by the bolts 30 and the gripping portion 20, thereby preventing concentration of stress. This prevents the flange 11 from deforming.

Also, when connecting the hose fitting 1 and the bracket 2,
The sleeve 10 is guided and attached to the lock 21 of the grip 20. Therefore, the hose 4 and the hose fitting 1 can be easily and reliably positioned. Furthermore, even if the fixing force of the fixing member 3 is loosened due to photography, etc. during use, the movement of the hose fitting 1 along the surface of the bracket 2 is restricted by the locking part 21, thereby preventing problems such as the hose 4 shifting from its position. .

J3, when the width of the space surrounded by the grip part 20 and the bracket 2 is larger than the width of the collar part 11, the function as a locking part is reduced, but the function as a grip part is maintained.

(Example 2) In the mounting structure of the second example shown in FIG. It is bent and raised to protrude from the surface of the bracket 2 toward the flange 11 side, and then roughly bent at a right angle and wrapped around the surface on the opposite side of the flange 11. This configuration is the same as that of the first embodiment except that two gripping portions 20 are formed. The surfaces of the locking portions 20 that face each other serve as locking surfaces 21.

In terms of structure, the mounting structure of this embodiment provides the same effects as those of the first embodiment, and since the grip portion 20 can be formed by cutting and raising the bracket 2, it is also excellent in weight reduction and yield.

(Embodiment 3) In the third embodiment shown in FIG. 4, the mounting of the embodiment 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, since the sleeve 10 is fixed within the cut groove 23, a locking surface 24 is also formed on the inner peripheral surface of the cut groove 23. That is, in this embodiment, the flange 11 is locked with the locking surface 21 of the gripping part 20, and the sleeve 10 is locked with the cut groove 2.
3, the movement of the hose fitting 1 along the surface of the bracket 2 is further prevented. In addition, the distance from the fixing point of the fixing member 3 to the gripping part 20 can be made longer than in the first embodiment, and the end of the flange 11 can be gripped, so that the moment when an overload is applied becomes smaller.
1 can be further prevented from deforming.

(Example 4) In the fourth example shown in FIG. 5, only one gripping part 20 is formed on one side of the bracket 2, and a cut groove 23 is formed in the bracket 2 as in Example 3. shows.

(Other Embodiments) FIGS. 6 to 9 show mounting structures of other embodiments. 6th
In the mounting structure shown in the figure, a U-shaped grip portion 20 cut and raised from the surface of the bracket 2 protrudes, and a cut groove 23 similar to that in the third embodiment is formed. This example is Example 3
The weight of the bracket 2 can be reduced compared to that of the bracket 2.

The mounting structure shown in FIG. 7 shows an example in which L-shaped gripping portions 20 protrude from both sides of the collar portion 11 to grip the bracket 2. As shown in FIG. Of course, this grip portion 20 may also be U-shaped.

In the mounting structure shown in FIG. 8, the legs on both sides of the cut groove 23 provided on the bracket 2 are bent into a U-shape to form the grip portion 20, and the wing portion 13 formed on the flange portion 11 is bent. I'm holding it. In this example, one inner peripheral side surface of the gripping part 20 is the locking surface 2.
1.

This example has the same functions and effects as the other examples, and is also excellent in weight reduction and varnished surface.

FIG. 9 shows another embodiment of the bracket 2. In this way, the kerf 23 can be formed not only from the end surface but also from the side surface. In this case, the locking surface 24 is attached to the bottom of the beam groove 23.
is formed.

In the above embodiments, the hose fitting is an intermediate holding part, but the present invention is not limited to this, and can be used as a fitting used at the end of a hose, or as a fitting for two hoses as shown in Fig. 10. 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, the shape of the sleeve, etc. are not particularly limited.
