Abstract
The utility model belongs to a measuring instrument. An expansion device of a drawing instrument is characterized by comprising drawing instrument installation seats, a support seat, a reinforcing rib and an installation hole, wherein the installation hole is arranged in the center of the support seat, the drawing instrument installation seats are arranged at two sides of the installation hole, the reinforcing rib is fixed on the support seat, the drawing instrument installation seat is fixedly connected with one end of the reinforcing rib, and spacing of inner edges of the support seat is 600mm. The expansion device of the drawing instrument enables an original drawing range to be increase to 600mm*600mm, is provided with an expansion tool which is large in testing range, easy and convenient to operate and high in practicality.
Description
Technical field
The utility model relates to a kind of surveying instrument, particularly a kind of drawing instrument measurement range expanding unit.
Background technology
Drawing instrument is in the construction stage, and there is very wide practicality in the stages such as factory's acceptance of materials.For example be used for the strong concrete Non-Destructive Testing; Anchor rod drawing instrument is applicable to the Site Detection of the anchor force of the anchoring bodys such as various anchor poles, reinforcing bar.Drawing instrument with in the digital display Chinese intelligent data processor instrument can directly read the axis force of anchor value, and automatically calculating, peak value maintenance, storage and query function are particularly suitable for testing laboratory and on-the-spot the use, and be simple to operate, is easy to learn and use.But the measurement of drawing instrument is generally less than normal, and the sample that original drawing instrument can only drawing 100mm * 100mm is fast, and it is just helpless soon to surpass the sample of 100mm in test like this.
Summary of the invention
The purpose of this utility model provides the device of an expansion drawing instrument measurement range, solves the less technical matters of existing drawing instrument measurement range.
The technical solution of the utility model: a kind of drawing instrument expanding unit, it is characterized in that: drawing instrument mount pad, bearing, reinforcement, mounting hole, there is mounting hole at the bearing center, the drawing instrument mount pad is in the mounting hole both sides, be fixed with reinforcement on the bearing, the drawing instrument mount pad is fixedly connected with reinforcement one end, and bearing inner edge spacing is 600mm.
Described reinforcement is trapezium structure, and reinforcement is identical with drawing instrument mount pad junction height.
Principle of work: at first experiment product to be measured is settled in the bearing 2, drawing instrument is installed on the drawing instrument mount pad 1, the ground tackle of drawing instrument is connected drawing hole 3 and connects determinand with bolt.Begin at last experiment, reach a conclusion.The utility model provides the device of an expansion drawing instrument measurement range, solves the less technical matters of existing drawing instrument measurement range.The utility model solves because the problem of the insufficient strength of the large bearing of span by reinforcement 4.
