The present invention relates to an attachment structure of the hose connecting member used for piping the hose. The attachment structure of the present invention can be used, for example, in attachment structures such as intermediate support parts for preventing looseness or contact with other parts when attaching a brake hose of an automobile to a vehicle body.

Background Art Conventionally, it is known to use a pair of male and female connecting members which can be screwed together to hold an intermediate portion of a hose. However, in such a connection member, the number of component parts increased and cost was high.

Therefore, Japanese Unexamined Patent Application Publication No. 59-6310 discloses an intermediate support part composed of a flange, a locking support portion, and a cylindrical portion. In this intermediate support part, a cylindrical part is inserted through a through hole provided in a bracket extending from a vehicle body, and the like is caught and positioned by a flange. will be.

According to this intermediate support part, the above-mentioned problem can be solved. However, it is unreasonable to insert the intermediate support part in which the hose is fixed into the through hole of the bracket to work in a narrow work space.

Therefore, as an actual attachment structure, the attachment structure as published in Unexamined-Japanese-Patent No. 60-178690 is used a lot. This attachment structure is provided with the cylindrical sleeve 101 through which the hose 400 is inserted, and the plate-shaped flange part 102 which protrudes radially from the outer peripheral surface of the sleeve 101 as shown in FIG. It consists of a hose connecting member 100, a plate-shaped bracket 200 extending from the skin attachment portion, a bolt 300 and a nut 301, overlapping the bracket 200 and the flange portion 102 bolt 300 ) And the nut 301. This attachment structure is excellent in workability in a narrow work space.

In the attachment structure of the hose connecting member disclosed in Japanese Patent Application Laid-Open No. 60-178690, the flange portion 102 is pivoted about the bolt 300 along the surface of the bracket 200 (Fig. 10). Perpendicular to the ground) is relatively easy. Therefore, the positioning accuracy at the time of attachment falls, and adhesion failure may arise. In addition, it may move slowly due to vibration or the like during use. Therefore, there is a need for a structure for attaching a hose connection member that does not have such a movement and has excellent positioning accuracy.

The present invention solves such a problem, improves the attachment structure disclosed in Japanese Patent Application Laid-Open No. 60-178690, maintains the workability in a narrow working space equally, and simultaneously rotates the hose connecting member. It is to provide a structure with a hose connecting member that can regulate the.

A hose connecting member attachment structure of the present invention includes a hose connecting member having a cylindrical sleeve through which a hose is inserted, a plate-like flange portion projecting in a radial direction from an outer circumferential surface of the sleeve, and a plate-shaped bracket extending from the skin attachment portion. And a fixing member such as a bolt and a nut, and in the attaching structure of the hose connecting member for attaching the hose connecting member to the bracket by fixing the flange portion and the bracket in the overlapping state, the hose connecting member and the bracket At least one side protrudes and has a locking surface which is engaged with the other side and has a locking surface approximately parallel to the plane including the fixing point by the fixing member and the axis of the sleeve, and the locking portion restricts movement along the surface of the bracket of the hose connecting member. It is characterized in that configured to.

Hose connecting member attachment structure of the present invention is composed of a hose connecting member, a bracket and a fixing member, wherein the hose connecting member is composed of a sleeve and a flange. A hose is inserted through the sleeve, and the hose is fixed by caulking, bonding, or the like. In addition, the inner tube may be inserted into the hose, and the hose may be fitted and fixed by the inner tube and the sleeve. This inner tube may be formed as a separate member from the hose connecting member, or may be formed integrally. In addition, only one sleeve may be provided on one side of the flange portion, or may be provided on both sides of the flange portion. Moreover, only one flange part may be sufficient and it can also provide more than one flange part.

As the fixing member, various fixing means known in the art, such as using a bolt and a nut and gripping with a clamp or the like, can be adopted.

The biggest feature of this invention is that it has a latching part in at least one of a bracket and a flange part. The locking portion has a locking surface that is substantially parallel to the plane including the shaft of the sleeve and the fixed point by the fixing member, while contacting the flange portion and the other side without the locking portion of the bracket, whereby the surface of the bracket of the hose connecting member The shape is not particularly limited as long as it is a configuration for restricting the movement according to the configuration.

As shown in the embodiments described later, for example, protruding from the bracket to abut on one or both sides of the flange portion, protruding from the flange to abut one or both sides of the bracket, or to the bracket It can be provided in the notch groove etc. of the width substantially equal to the outer diameter of a sleeve.

In addition, in the hose connecting member, ice may stick to the hose during use, and excessive load may be applied. In such a case, stress may concentrate on the fixed portion fixed by the fixing member, causing deformation of the flange portion. Therefore, in the structure with the hose connection member of the present invention, it is preferable to provide a gripping portion that protrudes from at least one side of the bracket and the flange portion to the other side and returns from the other side surface to the opposite surface. In this way, the grip part restricts the movement of the hose connecting member in the sleeve axis direction, thereby preventing the above irrationality.

In the hose attachment member attachment structure of the present invention, at least one of the hose connection member and the bracket is provided with a protruding locking portion having a locking surface that is in contact with the other side and is substantially parallel to a plane including a fixed point by the fixing member and the shaft of the sleeve, The locking portion restricts movement along the surface of the bracket of the hose connecting member. Therefore, according to the attachment structure of the hose connection member of the present invention, the positioning accuracy at the time of attachment is excellent and the movement to the bracket surface of the hose connection member is surely prevented even during use. Moreover, it can attach easily like a conventional thing, and also the workability in a narrow working space becomes excellent.
