2. Description of the Prior Art Pipe racks have been improved from the traditional screw-type to the screw-free, conventional positioning type shown in FIG. The known pipe rack of FIG.
The holding piece 11 is attached to the upright pipe 10, and the fitting ring 15 of the net rack 12 is provided outside the holding piece 11 to hold the holding piece 11.
The mesh rack 12 is positioned by pressing. An inner convex edge 14 is provided on the inner surface of the holding piece 11. The outer diameter of the sandwiching piece 11 is gradually reduced upward.
The inner convex edge 14 of the holding piece 11 is engaged and positioned in one annular groove 13 in which the upright pipe 10 is provided. The net shelf 12
The fitting rings 15 (only one of which is shown in FIG. 1) provided at the four corners of the above are gradually reduced in inner diameter from the bottom to the top. Fitting wheels 15 at each corner of the net rack 12 are provided outside the holding pieces 11 of the corresponding upright pipes 10, and the upright pipes 10 are tightly bundled by restraining the holding pieces 11. Thus, the net rack 12 is positioned.

[0003] Such a well-known pipe rack net rack 12
It is necessary that the fitting wheels 15 provided at each of the four corners are provided from the upper end of the corresponding upright pipe 10 to constrain the outside of the sandwiching piece 11 respectively. Therefore, when it is desired to increase or decrease the number of net shelves 12, the upper layer of the pipe rack has to be removed, which increases the complexity and difficulty of operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A pipe rack shelf positioning device according to the present invention comprises:
As shown in FIGS. The upright pipe 10 of the pipe rack 1 is provided with a horizontal groove 13 or a perforation (not shown), and a sandwiching piece 11 having an outer wall having a small top and a large bottom is provided for positioning. The rack rack shelf positioning device of the present invention includes a fitting wheel seat 20, which is a fitting wheel seat body 21 fixed to a mesh shelf 30 (see FIG. 8) or a rod 40, and the fitting wheel seat body 21.
It includes a pivot member 22 pivotally attached to the. The fitting wheel seat body 21 is formed by connecting one opening fitting wheel 24 to the end of the horizontal rod portion 23, and the opening 241 of the fitting wheel 24 is larger than the outer diameter of the upright pipe 10. The fitting wheel seat body 21 is provided with a vertical shaft 25, and a pair of upper and lower parts installed in the pivot member 22 penetrate through the corresponding perforations 26.
One closing portion 27 is connected to the front end of the pivot member 22,
The fitting ring is joined with the opening-shaped fitting ring 24 of the seat body 21 to jointly form one completed fitting ring. The features of the present invention are as follows. A pair of perforations 26 in the pivot member 22
Is an elongated perforation, and the pivot member 22 is movable back and forth with respect to the fitting wheel seat body 21 and rotatable. A dovetail-shaped projection 271 is provided at the front edge of the closing portion 27 of the pivot member 22, and a groove 242 is provided at a position corresponding to the front edge of the opening-shaped fitting wheel 24 of the fitting wheel seat body 21. The mutual engagement of the projection 271 and the dovetail groove 242 forms a complete fit ring. This is as shown in FIG.

By virtue of the design of the elongated perforations 26, the pivot member 22 can be moved slightly back and forth with respect to the fitting wheel seat body 21, and when the outer end of the elongated perforations 26 contacts the shaft 25 (ie, When the pivoting member 22 moves to the innermost side), the closing portion 27 of the pivoting member 22 forms a surrounding shape aligned with the opening fitting ring 24 of the fitting wheel seat body 21. This is as shown in FIG. When the inner end of the elongated perforation 26 comes into contact with the shaft 25 (that is, when the pivot member 22 moves to the outermost side), the closing portion 27 of the pivot member 22 has the opening-like fit ring of the fit wheel seat body 21. It has a complex shape with 24. This is as shown in FIG.

As shown in FIG. 4, when the present invention is operated, the pivot member 22 is pushed to the front (outside) and rotated to form a maximum tension angle with the fitting wheel seat body 21. The open fitting ring 24 of the fitting wheel seat body 21 can cover the outside of the upright pipe 10 of the pipe rack 1. Then, the pivot member 22 is rotated to bring the closing portion 27 of the pivot member 22 close to the opening fitting ring 24 of the fitting wheel seat body 21. This is as shown in FIG. Further, when the pivot member 22 is pushed to the rearmost (inward), the dovetail projection 271 of the pivot member 22 fits into the dovetail groove 242 of the fitting wheel seat body 21, and the closing portion 2
7 and the open fitting ring 24 combine to form one complete fitting ring. This is as shown in FIG. Figure 5
As shown in FIG. 5, if the fitting ring is further provided outside the sandwiching piece 11 positioned on the upright pipe 10 and the fitting ring is fixed, the rod 40 connected to the fitting ring seat 20 is connected.
Alternatively, the net rack 30 is positioned on the pipe rack 1. The rod 40 or the net shelf 3 provided with the above-mentioned fitting wheel sheet 20
When it is desired to remove 0 from the pipe rack 1, it can be smoothly removed by the operation in the reverse order of the above assembling process. Therefore, according to the present invention,
It is convenient to remove and can be operated quickly.

Clamping piece 1 in which the fitting ring 24 of the fitting wheel seat body 21 of the present invention and the closing portion 27 of the pivot member 22 are joined to each other to form a complete fitting ring attached to the upright pipe 10.
When restraining 1 and restraining 1, the fitting ring can hold the surrounding shape by the engagement of the dovetail-shaped projection 271 and the dovetail groove 242 among them.

The fitting ring formed by coupling the opening-shaped fitting ring 24 and the closing portion 27 gradually increases in inner diameter upward or downward and is combined with the outer diameter of the holding piece 11 to achieve the effect of tightening the slope. .

When the present invention is assembled to the pipe rack 1, as shown in FIG. 4, the upright pipe 10 is opened from the opening of the opening fitting ring 24 after being brought closer to the upright pipe 10 from the side. The fitting ring 24 is moved into the fitting ring 24, and the closing part 27 and the opening fitting ring 24 are closed to form a perfect fitting ring. .

The fitting wheel seat body 21 is a single rod 4
In addition to being able to be installed at both ends of 0, it can be installed at two corners or four corners of the net shelf 30, as shown in FIGS.

The present invention only needs to achieve the following requirements in manufacturing. 1. Fitting Wheel Opening 2 of Seat Body 21 Opening 2 of Fitting Wheel 24
The width of 41 is made larger than the outer diameter of the upright pipe 10, and a groove 242 is provided at the front edge of the opening-shaped fitting ring 24. 2. By closing the closing portion 27 of the pivot member 22 and the open fitting ring 24, a perfect fitting ring is formed.
In addition, a dovetail-shaped projection 271 is provided on the front edge of the closing portion 27 so that it can engage with the groove 242. 3. A pair of elongated perforations 26 are provided at the inner end of the pivot member 22 so that the shaft 25 of the fitting wheel seat body 21 can pass through.

Therefore, the present invention is manufactured in accordance with the registered No. 30583.
It is easier than the utility model of No. 73 and has more competitiveness in the market. Further, the fitting ring utilizing the engagement of the dovetail groove has a better structural force.

The shape of the fitting ring of the present invention is determined by the shapes of the upright pipe and the holding piece. In the embodiment shown in FIGS. 10 and 11, the upright pipe 10 'is of a two-wire type, and the holding piece 1
1'is provided with two grooves 111 ', and the open fitting ring 24' at the front edge of the fitting wheel seat body 21 'is formed into a flat elongated shape that can be combined with the outer diameter of the sandwiching piece 11'. There is. A convex block 112 is provided at the lower end of the holding piece 11 'so as to be positioned when the holding piece 11' is coupled with the upright pipe 10 '.
