Abstract

PROBLEM TO BE SOLVED: To provide a holder whose cylindrical member is neither deformed nor collapsed even if extremely high pressure is applied to a contact section when it is firmly fixed. SOLUTION: The mother member 13 of the holder incorporates elastic members 12 and 12' for holding the cylindrical member 11 and a clamping member 14, and the elastic members 12 and 12' are formed into an arc shape like the outer diameter of the cylindrical member 11, and the inner diameter of the elastic members 12 and 12' is made slightly smaller than the outer diameter of the cylindrical member 11. In attaching the holder to the cylindrical member 11, with the elastic members 12 and 12' held to the cylindrical member 11, the clamping member 14 is clamped. Then the elastic members 12 and 12' are deformed so as to fit to the outer diameter of the cylindrical member 11 and pressed against the cylindrical member 11 at the whole of the internal faces of the elastic members 12 and 12', resulting in the fixing of the holder without deforming the cylindrical member 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for easily and firmly detachably fixing and holding a cylindrical member, and more particularly, to a holding apparatus for fixing to a cylindrical member by a surface. is there.

[0002]

2. Description of the Related Art Conventionally, when attaching or detaching another member to or from a cylindrical member, the member has been fixed by using a U-shaped clamp.

[0003]

However, in the prior art, the shape of the portion sandwiching the cylindrical member of the clamp is
Since it is pressed against the cylindrical member at two or four points or lines, the pressure of the contact portion becomes extremely large when trying to fix more firmly, deforming the cylindrical member and further crushing the cylindrical member. It was easy to cause such problems. Further, in order to solve such a problem, there is an elastic member using rubber or the like in a portion to be sandwiched. In this case, however, the fixing force is insufficient, or the pressure is not sufficiently attenuated, and the cylindrical member is insufficient. It was easy to crush.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a plurality of arc-shaped elastic members having an inner diameter smaller than an outer diameter of a supporting cylindrical member are provided inside the clamp portion. One end or both ends are deformably attached, and when the elastic member is deformed along the cylindrical member at the time of attachment, the elastic member comes into pressure contact with the cylindrical member on the surface of the elastic member, and is further fixed by the elastic force generated by the deformation of the elastic member. It is an object of the present invention to easily and firmly detachably fix and hold the holding device without crushing.

FIG. 3 is a cross-sectional view illustrating a configuration of an example of a holding device when a base material of the holding device is movable, and FIG. 4B is a cross-sectional view illustrating a configuration in which the holding device is attached to a cylindrical member.

In FIG. 1, reference numeral 13 denotes a base material of a holding device, in which elastic members 12 and 12 'for holding a cylindrical member 11 and a fastening member 14 are incorporated. Elastic members 12 and 1
2 ′ is formed in an arc shape like the outer diameter of the cylindrical member 11. Also, the inner diameters of the elastic members 12 and 12 'are set to be somewhat smaller than the outer diameter of the cylindrical member 11.

In order to attach the holding device to the cylindrical member 11, the elastic members 12 and 12 'are aligned with the cylindrical member 11 and the tightening member 14 is tightened as shown in FIG. Since the inner diameters of the elastic members 12 and 12 ′ are set to be somewhat smaller than the outer diameter of the cylindrical member 11, the elastic members 12 and 12 ′ are deformed along the outer diameter of the cylindrical member 11 and pressed against the surface. Therefore, the holding device can be fixed without deforming the cylindrical member 11.

In FIG. 2, reference numeral 23 denotes a base material of the holding device, in which elastic members 22 and 22 'for holding the cylindrical member 21 and a fastening member 24 are incorporated. Elastic members 22 and 2
2 ′ is formed in an arc shape like the outer diameter of the cylindrical member 21,
The elastic members 22 and 22 ′ are fixed to the base material 23 and the tightening member 24 of the holding device as shown in the drawing so as to abut and deform when fixed. Further, the inner diameters of the elastic members 22 and 22 ′ are set to be somewhat smaller than the outer diameter of the cylindrical member 21.

In order to attach the holding device to the cylindrical member 21, the elastic members 22 and 22 'are aligned with the cylindrical member 21 and the tightening member 24 is tightened as shown in FIG. The inner diameters of the elastic members 22 and 22 'are set to be somewhat smaller than the outer diameter of the cylindrical member 21, and the elastic members 22 and 22' are in contact with each other. The holding device can be fixed without deforming the cylindrical member 21.

Next, an example in which the base material of the holding device is made movable is shown.

In FIG. 3, reference numerals 33 and 33 'denote a base material of the holding device, which is movable about a shaft 35.
The elastic members 32 and 32 'for holding the
Is incorporated. The elastic members 32 and 32 ′ are formed in an arc shape like the outer diameter of the cylindrical member 31.
And 32 'are fixed to the base materials 33 and 33' of the holding device as shown in the figure so as to abut and deform when fixed. The elastic member 3 is larger than the outer diameter of the cylindrical member 31.
The inner diameters of 2 and 32 'are set somewhat smaller.

In order to attach the holding device to the cylindrical member 31, as shown in FIG. 3 (b), the elastic members 32 and 32 'are aligned with the cylindrical member 31 and the tightening member 34 is tightened so that the shaft 35 is centered. The holding members 33 and 33 'of the holding device are movable, and the inner diameters of the elastic members 32 and 32' are set to be somewhat smaller than the outer diameter of the cylindrical member 31 as described above, so that the elastic members 32 and 32 'come into contact with each other. Therefore, the elastic members 32 and 32 ′ are deformed along the outer diameter of the cylindrical member 31 and are pressed against each other, so that the holding device can be fixed without deforming the cylindrical member 31.
