Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clamp that is wrapped around a member and fastened to fix the member.

[Conventional technology]

As shown in FIG. 4, the plate material 2 is wrapped around the member 4, its both ends are bent outward to form fastening parts 6 and 8, and these fastening parts are tightened with bolts 10 and nuts 12. Clamps are known from the prior art.

[Problem that the invention attempts to solve]

For example, as shown in FIG.
If a tightening margin is provided, the tightening portions 6 and 8 will open from the bent portion 14, resulting in a reduction in the binding force. In addition, as shown in Fig. 4 above, when tightening the entire surfaces of both clamping parts 6 and 8 in close contact, the binding force becomes unstable due to variations in the thickness of the member 4 fixed by this clamp. There were drawbacks such as:

The present invention has been devised to eliminate the above-mentioned drawbacks, and provides a clamp that can securely fix members together with stable clamping force.

[Means for solving problems]

In the clamp according to the present invention, a plate material is wrapped around a member, both ends of which are bent in the same direction to form a clamping part, and the end of one clamping part is moved toward the other clamping part. It is bent and then tightened and fixed with the tip of this bent part in contact with the other tightening part.

[Effect]

In the clamp according to the present invention, the tip of the bent portion is used as a fulcrum and the member is fastened with a stable binding force.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments. FIG. 1 shows a case where a clamp 20 according to an embodiment of the present invention is applied to a power steering device, in which two pipes 24 and 26 of hydraulic piping are fixed to a cylinder 22.

The clamp 20 includes a first clamp member 28 having an arc shape along the circumferential surface of the cylinder 22, and two pipes 2.
4 and 26 against the outer surface of the cylinder 22, and a second clamp member 30 in which a recess 30a for accommodating the pipes 24 and 26 is formed.

At one end of both clamp members 28, 30,
The pawl 30b of the second clamp member 30 is engaged with the notch of the first clamp member 28 to connect both 28 and 30, and the other end has a tightening bolt bent in the same direction. Portions 28a and 30c are formed, and a nut 34 is screwed onto a bolt 32 passing through the holes of both of these tightening portions 28a and 30c, and is tightened and fixed.

The clamping part 28a of the first clamping member 28 has a flat plate shape, and the clamping part 30c of the second clamping member 30 has a tip 30d of the flat plate at an angle of about 90 degrees toward the first clamping member 28. It is bent.

When tightening both the tightening parts 28a and 30c with the bolt 32 and nut 34, as shown in an enlarged view in FIG. , the first
It is brought into contact with the tightening portion 28a of the clamp member 28 and is tightened and fixed. As shown in FIG. 3, when the bent portion 30d is fixed without contacting the mating tightening portion 28a, the tightening force is small, but the bent portion 30d
When the tips are brought into contact, the bending portion 30d is fastened using the tip as a fulcrum, so a strong binding force can be obtained.

Note that this clamp 20 is not limited to use in a power steering device, and can be applied to various other uses. Further, in the above embodiment, the case where the two clamp members 28 and 30 are connected is shown, but the present invention is not limited to this, and the clamp 2
The shape of 0 is not limited to the above-mentioned shape, but may be appropriately determined depending on the outer shape of the members 22, 24, and 26 to be tightened and fixed.

[Effect of idea]

As described above, according to the present invention, members can be reliably fixed with stable binding force.
