Problems solved by technology

Due to the complex ground and underground conditions at the construction site, the pre-designed buried depth is inconsistent with the actual excavation depth, resulting in the problem of returning the extended transmission rod to the manufacturer for re-production, which delays the progress of the project

Embodiment

[0020] Such as figure 1 , figure 2 As shown, a transmission rod that is convenient to be shortened includes a transmission cap assembly and a transmission pipe 1, wherein the transmission cap assembly includes a nut 2, a compression plug 3, a transmission cap 4, and a screw 5. The transmission pipe 1 is a square pipe, and its length can be determined after calculation according to the predetermined buried depth of the valve. Described nut 2 is square, and the center is provided with threaded hole. The compression plug 3 is a square rubber block with a V-shaped slope 7 on the top, toothed sides 6 on both sides, and a through hole 8 in the middle. One end of the transmission cap 4 is square-conical, the other end is square, and a countersunk bolt hole is arranged in the middle. The screw 5 is a countersunk screw with a flat groove at the end. The screw 5 passes through the transmission cap 4, the nut 2 is screwed on the other end, and the compression plug 3 is clamped in th...

Abstract

The present invention relates to a transmission rod convenient for truncating; the transmission rod comprises a transmission cap assembly and a transmission tube, wherein the transmission cap assembly comprises a nut, a bulging plug, a transmission cap and a bolt, wherein the bolt passes through the transmission cap; the nut is threaded to the bolt; the bulging plug is disposed between the nut and the bolt; the transmission cap assembly is inserted into an inner hole of the transmission tube. Compared with the prior technology, the transmission rod of the present invention has the advantages that the assembling and disassembling of the transmission cap assembly are performed only by turning the bolt, and the operations can be performed repeatedly and at any time, and the length adjustmentof the transmission rod at site is realized; the structure is simple, and the construction is convenient.

Description

technical field [0001] The invention relates to a transmission rod, in particular to a transmission rod which is convenient for shortening. Background technique [0002] In my country's urban water supply and drainage pipe network, most of the valves are directly buried in the ground, and the transmission rod needs to be lengthened to the ground level. The existing extended transmission rod is made into a fixed length by the manufacturer according to the pre-designed buried depth of the valve, and then installed and constructed on the site. Due to the complex ground and underground conditions at the construction site, the pre-designed buried depth was inconsistent with the actual excavation depth, resulting in the problem that the extended transmission rod was returned to the manufacturer for re-production, which delayed the progress of the project. Contents of the invention [0003] The object of the present invention is to provide a transmission rod with adjustable leng...
