Description

[Detailed Description of the Invention] The present invention relates to a telescopic rod device for construction such as a house raising machine that can be extended against a load with a simple operation, and its configuration will be explained in detail with reference to the attached drawings. The details are as follows.

Abutment pieces 3 and 4 are attached to the other ends of a small-diameter pipe 1 and a large-diameter pipe 2 whose ends are fitted into each other.

A rectangular tube 5 with an even larger diameter is connected to this large diameter pipe 2.

A row seat plate 7 provided with a fitting hole 6 is fitted into the small-diameter pipe 1 inside this square tube 5 with a little margin.

The drawing shows a row seat plate 7 in which the upper part of the row seat plate 7 does not protrude from the engagement holes 8 and 9, but a protruding rod 10 is provided on the row seat plate 7, and the row seat plate 7 is tilted using the protrusion rod 10 as an operating rod. Raise the small diameter pipe 1
The figure shows a case in which the slide of the screen is enabled.

Both edges of this row seat plate 7 are made to protrude from engaging holes 8 and 9 formed on two sides and having a movement width.

A carded cotton spring 12 is interposed between the row seat plate 7 and the end wall 11 of the square tube 5, and the lower edge of one engagement hole 8 is positioned above the lower edge of the other retaining hole 9. The row seat plate 7 is provided so as to engage the small diameter pipe 1 diagonally and lock the small diameter pipe 1 from being inserted.

The telescoping rod a having the above structure is inserted from the engagement hole 8 side, and the small diameter pipe 1 is slid in the direction of extending the telescoping rod a while pushing the row seat plate 7 by lever action and receiving the load. It consists of a lever operating rod 14 having a bifurcated portion 13 formed at its lower end for movement.

In the drawing, the piece 3 is not attached to the tip of the small-diameter pipe 1, and a joint pipe 12 of a smaller diameter is inserted into the short pipe 1, and the pin 13 is used to lock the joint. The figure shows a case where it is made into a two-part type for convenient carrying during use.

In the figure, reference numeral 7' is a row seat plate, 8' is a retaining hole, 11' is an end wall, 12' is a carded thread, 15 is a locking bolt for tilting the row seat board 7, and 16 is a row seat board 7. 17 is a fitting hole for the bifurcated mold part, and 6' is a fitting hole.

To explain the case where the main business side is used as a house raising machine, the upper and lower contact pieces 3 and 4 are positioned at the diagonal intersections of the pillars as shown in Figure 1, and the slanted corners are Seat board Otsu 7
: Card the protruding end in the direction of the arrow in Figure 3 12.12
If you compress ' and press it by hand (push the protrusion 10), the square seat plate 7.7' (7) and the fitting holes 6, 6' will be large enough to accommodate the small diameter pipe 1. Because there is a small diameter pipe 1
is extendable and retractable, and the upper and lower contact pieces 3 and 4 are stretched out from the small-diameter pipe 1 and brought into close contact with the intersecting corner, and the proposed product is installed diagonally at the intersecting corner of the pillars.

In this state, insert the bifurcated part 13 of the lever operating rod 14 into the engagement hole 8.
When it is inserted into the square tube 5 and the lever operation rod 14 is repeatedly vibrated using the rear end of the engagement hole 8 as a fulcrum, the engagement hole 9 side of the square seat plate 7 is pushed by the lever action and the small diameter pipe 1 is pushed together. It slides in the direction of protrusion by the amount of pressure that is pressed, producing a jacking effect.

Therefore, the construction of the house will be carried out, and the pillars will be able to be properly vertically corrected.

Also, if the pieces 3 and 4 of this product are made into flat plates, they will become telescopic support columns that support the ceiling.

In either case, when the square seat plate 7 is pushed in the direction of the arrow in FIG. 3, the small-diameter pipe 1 can be slid, and the small-diameter pipe 1 is retracted a little and removed from the pillar.

As mentioned above, the present invention is a type in which two pipes are fitted and jointed, so it can be set to any length, and the joint is secured by frictional resistance based on the inclination of the square seat plate created by the carded fibers. It is highly practical as it can withstand a large load while being locked, and the jacking action can be performed reliably as well, and the jacking operation can also be performed reliably by simply vibrating the lever operation lever. It can be used as a telescopic rod device for construction such as house raising machines.
