JP3039156U - Length adjustment device for lightly loaded support pipe - Google Patents

Abstract

(57) [Summary] (Corrected) [Purpose] When the strut 1 is made of pipe, when adjusting the length of the light-load strut pipe finely, a part of the longitudinal direction is added to the end of the strut pipe 1, Or, by forming a concave female screw part 4 without changing the wall thickness to several threads and utilizing it as a female screw,
It is hoped that parts such as nuts and the labor for mounting them will be saved, and that the price will be low and the strength will be maintained. [Structure] This invention, when the strut is made of a pipe, finely adjusts the length of the light-load strut pipe, and changes the wall thickness in a part of the longitudinal direction at the end of the strut 1, or in several lines. By using the female screw part 4, which is recessed without being used, as a female screw, and rotating the handle 6 of the fine adjustment device 2, which is integrated with the male screw 5 that is inscribed and fitted to this, A fine adjustment device for the length of a lightly loaded support pipe that performs fine adjustment by moving the support up and down according to the principle.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 A fine adjustment device for the length of a lightly loaded support pipe.

[0002]

[Prior art]

 Nut 8, which is attached to the end of the support pipe 1 by welding,

[Fig. 1] Or directly a strut Female screw threaded inside the pipe 10,

[Fig. 2] A bolt 7 is set in Fig. 2 and fine adjustment of the length of the support pipe is performed by rotating the head 9 for fine adjustment of the bolt.

[0003]

[Problems to be solved by the device]

 Generally, the nut 8 is joined to the end of the support pipe 1 by welding or the like.

FIG. 1 is a female screw threaded directly inside the support pipe,

[Fig. 2] is adjusted by rotating the bolt head 9 by setting the adjusting bolt 7 on the other hand, but the present invention does not require the nut 8 and welding work for mounting the nut 8. In addition to eliminating it, in order to avoid strength inferiority due to damage to the wall thickness by directly threading the support pipe 1, it was recessed without changing the wall thickness.

FIG. 3

[FIG. 4] A female screw portion 4 is formed and utilized as a female screw.

[0004]

[Means for Solving the Problems]

 Prop pipe 1, a part of the end in the vertical direction or several recessed female screw parts 4,

FIG. 3

[Fig. 4] Depending on the installation, separate parts 8 and their mounting work are not required, and a part of the support pipe is for fine adjustment.

FIG. 7 is used as a female screw for molding.

[0005]

[Action]

 Providing recessed female screw parts 4 in a part of the vertical direction of the column 1, or in the end part, and utilizing it as a female screw.

FIG. 3

[Fig. 4], a fine adjustment device 2, which is integrated with a male screw 5, which is inscribed and fitted in this

By rotating the handle 6 shown in FIG. 5, the strut is moved up and down by the principle of the screw, and the length of the strut tube is finely adjusted.

[0006]

【Example】

 When finely adjusting the length of a lightly loaded strut pipe when the strut is made of pipe, generally, the nut 8 is joined to the end of the strut pipe 1 by welding or the like.

FIG. 1 is a female screw 10, which is directly threaded inside a support pipe,

[Fig. 2] For example, the bolt 7 is set and the head 9 for fine adjustment of the bolt is rotated for adjustment. This product has this nut 8 and welding for mounting it. In addition to eliminating work, etc., in order to avoid strength inferiority due to damage to the wall thickness by directly threading the support pipe 1, the support pipe 1, part of the end in the vertical direction Dented without changing the thickness

FIG. 3

[FIG. 4] Since the female screw portion 4 is formed and used as a female screw, the strength and cost of the conventional fine adjustment device of this type can be boasted.

[0007]

[Effect of the invention]

 Vertically at the end of the support pipe 1, without changing the wall thickness

FIG. 3

[FIG. 4] Since the female screw portion 4 is formed and utilized as a female screw, the strength is first of all, and secondly the price is low.
