JP3001776U - Small diameter tube fixing device - Google Patents

Abstract

(57) [Summary] [Purpose] When fixing a small diameter pipe, the conventional bolt tightening requires a long working time, and the problem of loosening the screw after tightening is a problem. Screwless structure for large-scale processing. [Structure] The rectangular support tube 1 supports a small-diameter tube, and has an axial groove on its upper surface. A pair of symmetrical fasteners 2 are inserted and locked in this groove at the lower end, and after bending the upper surface of the small diameter pipe so that they can embrace each other, stand up at appropriate intervals and bend the uppermost end so that they can butt. There is. The scissors metal fitting 3 has a C shape, and the rising portion of the tightening metal fitting can be sandwiched, and is clamped by a crimping tool.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This is a device for fixing small-diameter pipes, which eliminates the use of screws, simplifies work, and eliminates obstacles due to loosening of the screw. Although it is not strictly a small-diameter pipe, it refers to a diameter of about 76.3 mm or less.

[0002]

[Prior art]

 Screws are used for tightening when fixing the small diameter pipe P on the base. 3 and 4 illustrate the case of using the U band a and the U bolt b. However, in power plants and chemical plants, many long small-diameter pipes are often arranged in parallel, and in that case, the number of fixing points required is enormous. Bolting this one by one cannot bear it. Checking and repairing looseness due to vibration requires unexpected time and effort.

[0003]

[Means for solving problems]

 The fixing device shall be without screws. The upper end of the small-diameter pipe is held oppositely by a pair of facing metal fittings whose lower end is locked to the base, the upper part of which is isolated so as to have an appropriate tightening margin, and the end is formed at the abutting edge. Insert a scissors into this part from the pipe axis direction, cover it, and compress it with a crimping tool.

【Example】

 1 and 2 will be described. The support cylinder 1 has a rectangular cross section and is fixedly placed on the floor surface, and has a groove 1a on the upper surface. The fastener 2 consists of a pair of symmetrical tape-shaped members, and has a wide portion 2a at the lower end. When it is turned 90 degrees after being inserted into the groove 1a, it is locked by the wide portion 2a. The fasteners 2 are curved so as to be able to hold the upper surface of the small-diameter pipe P so as to be held, rise up at appropriate intervals, and the ends bend inward to form the butt edges 2b. The scissors metal fitting 3 has a C-shaped cross section, and this rising part is inserted from the axial direction of the pipe to be sandwiched, and the sandwiched product can be compressed by a crimping tool. FIG. 1 shows a state in which the rising portion of the fastener is deformed by this compression and the small diameter pipe P is tightened.

Both the clamp 2 and the scissors 3 are easy to mass produce. It is easy to install and can be tightened with one touch using hydraulic tools.

[0006]

【effect】

 Eliminates the need to tighten bolts and worry about loosening screws. Even small diameter pipes with different diameters can be handled by adjusting the compression amount.

Claims (1)

[Scope of utility model registration request] 1. A rectangular support tube that is fixed to the floor and has a longitudinal groove on the upper surface to support a small diameter pipe in a direction perpendicular to the groove, and a lower end inserted into and locked in the supporting cylinder groove so that the upper surface of the small diameter pipe is opposed to the supporting pipe. A small-diameter pipe consisting of a pair of facing metal fittings that have been bent so that they can be held, then rise up at appropriate intervals and are bent so that the uppermost ends can abut, and scissor metal fittings that can clamp the upper part of the pair of metal fittings.
