Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for connecting a plurality of superposed members.

[0002]

2. Description of the Related Art Conventionally, when a plurality of members are superposed and joined, a hole is formed through the superposed members, a bolt is inserted into the hole, and a nut is screwed onto the tip of the bolt. The superposed members are clamped and fixed. Further, in order to prevent the superposed members from rotating relative to each other, two or more bolts and nuts are tightened to prevent rotation.

[0003]

In the conventional structure described above, when the thickness of the superposed members is large,
The bolt is also long and large, and the head of the bolt is inevitably large. Further, after the bolt and the nut are tightened, the bolt and the nut are projected on the surface of the superposed members.
Therefore, when the devices are mounted on the surfaces of the superposed members, it is necessary to avoid the positions of the bolts and nuts, so that the mounting position is limited. Further, there is a problem that a bolt and a nut must be added to prevent the rotation.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fixing structure for stacked members in which the protruding portions protruding on the surfaces of the stacked members can be minimized.

[0005]

In the fixing structure for stacked members according to the present invention, a plurality of members are stacked, at least two holes in different directions are formed in these members, and the holes are stacked in each hole. The feature is that a connecting member for connecting the members is inserted.

[0006]

According to the present invention, if the connecting member is inserted into at least two holes formed in the superposed members and having different directions,
Since the superposed members are fixed inseparably, the protruding portions that project on the surfaces of the superposed members can be reduced as much as possible.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. The superposed member 20 includes a first member 1 and a second member 2. These members 1,
2 are overlapped with each other, and holes 3 and 4 having different directions penetrating both are formed. The first hole 3 includes a hole 3a of the first member 1 and a hole 3 of the second member 2 which are concentrically formed.
b and. Similarly, the second hole 4 and the hole 4a of the first member 1 and the second member 2 which are formed concentrically are formed.
And the hole 4b. The axes of the holes 3 and 4 may be formed on the same plane at different intersecting angles α and β with respect to the members 1 and 2, and the holes 3 and 4 may be formed.
The axis 4 may be formed so as to be located on two planes as shown in FIG.

The first connecting member 5 has a cylindrical shape,
It is inserted into the first hole 3 in a press-fitted state and pressed against the inner surfaces of the holes 3a and 3b. The second coupling member 6 has a cylindrical shape, and is inserted into the hole 4 in a press-fitted state so that the hole 4 a and the hole 4
It is pressed against the inner surface of b. A hole 7 penetrating the first coupling member 5 and reaching the first member 1 is formed at an end of the first coupling member 5, and a retaining pin 8 is press-fitted therein. Further, a hole 9 penetrating the second coupling member 6 and reaching the first member 1 is formed at the end of the second coupling member 6,
The retaining pin 10 is press-fitted therein.

The above-described embodiment has the following effects. That is, 1, the first coupling member 5 in the hole 3 of the first member 1
When the second coupling member 6 is inserted into the hole 4 of the second member 2 and the second coupling member 6 is fitted into the hole 4 of the second member 2, the two members are fixed inseparably. Second member 2
No need to tighten. Therefore, the connecting members 5 and 6 do not need a head, and the portions where the connecting members 5 and 6 project from the surfaces of the members 1 and 2 can be made as small as possible, regardless of the positions of the connecting members 5 and 6. The device can be attached to the surfaces of the members 1 and 2.

2, the first member 1 and the second member 2
However, if the first connecting member 5 and the second connecting member 6 are pressed against the inner surfaces of the holes 3a, 3b and 4a, and 4b, respectively, if they try to move in the separating direction, their movement is blocked. , The first member 1 and the second member 2 are never separated.

3. In particular, in the above embodiment, since the retaining pins 8 and 10 are provided between the first member 1 and the first coupling member 5 and the second coupling member 6 as retaining devices,
It is possible to loosen the control of the press-fitting margins of the coupling members 5 and 6 into the holes 3 and 4, and to facilitate the production and assembly of parts.

The above embodiment is not limited to the embodiment shown in the drawings. For example, although the connecting members 5 and 6 are formed in a cylindrical shape, a cylindrical shape, an oval shape, a square shape, or a polygonal shape may be used. Well, as the retaining means for the coupling member, various known means can be applied. Furthermore, if the press-fitting state of the coupling member into the hole is managed, it is not necessary to use the retaining pin. Various modifications are possible without departing from the spirit of the invention.

FIG. 3 shows a second embodiment of the present invention, which differs from the first embodiment in the structure of the holes and the connecting members. Since the structure of the two holes and the connecting member is the same,
On behalf of this, the first hole and the first coupling member will be described. The first hole 21 includes a hole 21 a that penetrates the first member 1 and a hole 2 that is formed in the second member 2 in a non-penetrating state.
1b and. In addition, the first coupling member 22
Is inserted into the first hole 21 in a press-fitted state and pressed against the inner surfaces of the holes 21a and 21b.

FIG. 4 shows a third embodiment of the present invention. The difference from the first embodiment is that the groove 23 is formed in the end portion of the first coupling member 5, and the first member is formed. The recess 24 is formed in the recess 1 and the stop ring 25 inserted into the groove 23 is accommodated in the recess 24.

FIG. 5 shows a fourth embodiment of the present invention, which differs from the first embodiment in that both ends of the first connecting member 5 are caulked to form a head 26. is there. Also in these second to fourth embodiments, the same effect as that of the first embodiment can be obtained.

[0016]

According to the fixing structure for superposed members of the present invention, a plurality of members are superposed, at least two holes in different directions are formed in these members, and the superposed members are connected to the respective holes. Since the coupling member is inserted and fitted, it is possible to minimize the protrusions protruding on the surface of the superposed members, and to add an additional device to the surface of the superposed members regardless of the position of the coupling member. It has a great effect. Further, unlike the case of using bolts and nuts, the head does not project and there is no need to form screws, so the strength can be increased and the manufacturing cost can be reduced. Further, since the members can be joined by inserting the joining member, the working time for facilitating the assembling can be shortened.
