Abstract
The utility model discloses a telescopic height measuring ruler, which comprises a main body and at least one telescopic section positioned inside the main body. The inner diameter of a front telescopic section matches with the outer diameter of a rear telescopic section; adjacent telescopic sections are movably connected; and scale marks are arranged on the telescopic sections. The technical scheme of the telescopic height measuring ruler includes that the telescopic sections are arranged inside the main body, and then the height measuring ruler is capable of optionally expanding, bringing convenience for workers to carry and being not easy to be damaged. When in height measuring, an individual can complete operation independently, and the operation is not affected by severe weather such as wind and the like, thereby increasing working efficiency. Besides, the telescopic height measuring ruler adopts stainless steel materials and has the scale marks accurate to mm.
Description
Technical field
The utility model relates to a kind of ruler, specifically relates to a kind of ruler of measuring height.
Background technology
In engineering survey, use steel tape the measuring of surveying instrument (as total powerstation, GPS reference station etc.) height, because steel tape softness, when measuring, need during height of instrument other people to help to pin the ruler bottom and assist to measure, as run into that a people can't independently finish measurement when inclement weather such as blowing at all.When after measuring height of instrument, receiving steel tape,, careless slightlyly will scratch finger because its contraction speed is than very fast.Cracky often appears fractureing, twisting and warping in coil of strip.
Summary of the invention
The purpose of this utility model provides a kind of scalable and height measuring device of frangibility not.
For achieving the above object, the utility model is by the following technical solutions:
At least one joint telescopic joint that the utility model comprises body and is positioned at body interior, the internal diameter of last telescopic joint matches with the external diameter of back one telescopic joint, flexibly connects between the adjacent expansion joint; On telescopic joint, be provided with scale.
Above-mentioned telescopic joint has 50 joints.
Above-mentioned body and telescopic joint all adopt stainless steel.
Adopt the utility model of technique scheme, be provided with telescopic joint in body, height measuring device can stretch arbitrarily like this, make things convenient for the staff to carry and cracky not, in that survey when high can people's independence complete operation, the boisterous influence such as do not blown improved work efficiency.In addition, the utility model adopts stainless steel, and the scale that is accurate to mm is arranged.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Fig. 2 is the annexation figure between the adjacent expansion joint in the utility model.
Embodiment
As shown in Figure 1, at least one joint telescopic joint 2 that comprises body 1 and be positioned at body 1 inside, the internal diameter of last telescopic joint matches with the external diameter of back one telescopic joint, flexibly connects between the adjacent expansion joint 2; On telescopic joint 2, be provided with scale.
The quantity that it is pointed out that telescopic joint 2 can be set according to actual needs, thereby adjusts the length of height measuring device.In the present embodiment, telescopic joint 2 has 50 joints, also can only be a joint, ten joints, 30 joints, 60 joints or the like in addition.
As shown in Figure 2, in the junction of adjacent two telescopic joints, slideway is set cooperates, promptly the afterbody at previous telescopic joint is provided with Ka Tai, boss is set, the telescopic moving in the inner chamber of last telescopic joint of back one telescopic joint at the leading section of back one telescopic joint.
For easy to use, body 1 and telescopic joint 2 all adopt stainless steel, and each telescopic joint scale is divided into 10cm, total length 2.0m.
