Description

[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION The present invention relates to a fixture for securing tubes.

[Prior art and problems]

In some types of fixtures for fixing pipes to walls, etc., the basic structure consists of a half-shaped member for fixing the pipe to the wall, etc., and another half-shaped member that is connected to this half-shaped member with screws. It is something. Another type of pipe fixture fixes the pipe by bringing the pipe into direct contact with a wall surface etc. and attaching the pipe fixture to the pipe. This type of pipe fixture consists of a single part, This part surrounds the pipe and is fixed to the wall using fixing devices such as screws.

Fixing a tube using such a conventional tube fixing device is not quick and time-consuming. The first reason is that a large number of screws and other fixing members must be used to secure the pipe fixture, and the second reason is that the pipe to be fixed must be used during the installation work of the pipe fixture. This is because it is difficult to support.

[Purpose of the invention]

The object of the invention is to eliminate the above-mentioned drawbacks and to provide a pipe fixture that is easy to install. Preferably, the structure of the tube fixture is such that one of the constituent members of the tube fixture is fixed at a fixed position on the tube, and the tube is supported by this fixing member.

[Summary of the invention]

The tube fixing device according to the present invention consists of two cooperating components, which are combined to surround the tube to be fixed, and one of which is used to fix the tube to a wall or other surface. This fixing part is of the type that fixes the tube.

According to the invention, the edge portions of the longitudinal (or lateral) parts of the two components have recesses and projections that cooperate to combine the two components. These components have a shape that allows them to be joined to the other component by moving one component in the axial direction, and after the two components are combined, the combined parts It has a structure that does not separate in the radial direction due to action. Each side edge of the structural portion of each component has a protrusion and a recess, the protrusion and the recess extending axially between the ends of the structural portion for engagement. is preferred.

Preferably, the portion of the protruding portion surrounding the tube is shaped so that there is no step so that the tube fixture is aligned with the tube, and the tube fixture does not protrude when the components are assembled. There are no sections so that the inner surface of the tube fixture smoothly surrounds and supports the tube to be secured.

The structural member on the side that is fixed to the wall surface of the pipe fixture has an inner cross-sectional shape of a circular arc with an angle slightly larger than 180°, is made of a material with some elasticity, and the side along the longitudinal direction Preferably, the edges flare away from the longitudinal direction during insertion of the tube. If the diameter of the tube to be fixed is appropriate, the tube can be held by the elasticity of the tube fixture.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.
The pipe fixture according to the invention, as shown, consists of two symmetrical halves 1, 2, one of which is provided with a radially extending projection or sleeve 3. A screw 4 passes through this protrusion or sleeve 3, and this screw 4 is fixed to a surface such as a wall 5, for example.

As can be seen, each half has a channel-shaped portion and a cylindrical portion. One axial end of this groove-shaped portion is deep, and the inner side of the cross-section of this deep portion is circumferential and wider than 180°. As shown in FIG. 2, these parts are the left part of the mold half 1 and the right part of the mold half 2. The remaining portions of each half are shallower and have a circumferential extent of less than 180°. Therefore, the symmetrical half mold members 1 and 2 have a complementary relationship in which the concave and convex portions face each other. This half mold member is
As shown, they are assembled to surround the tube 6 and are aligned with the outer surface of the tube 6.

The longitudinal side edges of the two half-shaped members 1 and 2 have protrusions and recesses, respectively. This one side edge is in a complementary relationship with the other adjacent side edge. Furthermore, the side edge of one of the two half-shaped members 1 and 2 faces the side edge of the opposite half-shaped member. The recess allows the two halves 1, 2 to be combined so that they can move half way relative to each other along the axis (FIG. 2).

More specifically, each of the protrusions includes the half-shaped member 1,
It protrudes like a tongue in the axial direction from the deeper groove of No. 2.
The tongue portion is spaced apart from the shallower channel portion to form an axially truncated recess between the tongue portion and the channel portion. As shown in FIG. 3, the protrusion on the side edge of one mold half engages with the recess on the side edge of the other mold half adjacent thereto.

At the position where the two parts are assembled, the mold halves can be separated by an axial movement;
There is no separation in the radial direction, and there is no separation in the lateral and radial directions after the interocclusion.

As shown in FIGS. 1 and 4, the protruding tongue portion becomes part of a cylindrical portion formed by combining the half-shaped members, and the boundary between the tongue portion and the adjacent portion is Do not create any steps in the area.

Attaching the tube fixture to the tube is extremely simple. After determining the route in which the tube is to be installed, the radial members 1 of the tube fixture are secured at appropriate intervals using screws or other conventional fasteners.

Next, a tube of a predetermined length is pushed into the half mold member 1 from the radial direction. This mold half has a channel-shaped portion whose inner cross-section extends over 180°, as described above. This portion has a certain degree of elasticity, and when the tube is inserted, the side edges widen and can temporarily support the inserted tube. In this way the tube is fixed in place on the mold half 1. Since the side edges of the half-shaped member have elasticity, they can sufficiently frictionally hold the press-fitted tube.

Next, the half mold member 2 is placed over the press-fitted pipe and pushed down, moved in the axial direction, and the half mold member 1,
The recesses 7 and 8 of 2 are engaged. The half mold parts interlocked in this way will not separate unless the mold half parts 2 are moved in the axial direction.

As will be apparent from the foregoing discussion, once the tube fixtures have been engaged and the tube has been aligned in the mold halves as described above, the tube installation is substantially complete.
The tube fixture shown in the figures is extremely simple in construction and allows for a much wider range of tube attachments than previously known fixtures.
