Abstract
The utility model relates to a dedicated drawing engineer's scale of engineering cost. A dedicated drawing engineer's scale of engineering cost which has mainly constructed: but chi base, roller cover, chi slat, gyro wheel sight glass, roller bearing, protractor, the chi base on the centre gripping be fixed with the chi slat, chi base one side be roller cover, roller cover embeds the roller bearing, two ends of roller bearing are equipped with the gyro wheel, the chi base inside period number put and be equipped with the protractor, but roller cover on be equipped with the sight glass. The utility model discloses simple structure, low in cost, be applicable to the engineering cost drawing and calculate engineering volume and get the use, abandon traditional triangle proportion chi in the product design, adopted the mode of removable chi slat to replace.
Description
Technical field
The utility model relates to the special drawing scale of a kind of construction costs.
Background technology
Scale is the ratio of the physical length representing the length of a line segment on figure line segment corresponding to ground. Formula is: the ratio of scale=map range and actual range. Scale has three kinds of method for expressing: digital proportional chi, graphicscale and word scale. Generally, large-scale map, content is detailed, geometric accuracy height, can be used for measuring on figure. Small proportion chi map, content summarisation is strong, is unsuitable for and carries out measuring on figure.
Summary of the invention
The purpose of this utility model is to provide the special drawing scale of a kind of construction costs.
The utility model solves its above-mentioned technical problem and is adopted following technical scheme: the drawing scale that a kind of construction costs is special, its major constituents has: chi pedestal, drum sleeve, chi batten, roller, visible mirror, roller bearing, protractor, described chi pedestal has gripped chi batten, described chi pedestal side is drum sleeve, the built-in roller bearing of drum sleeve, roller bearing two end is provided with roller;
In described chi pedestal, middle section position is provided with protractor;
Described drum sleeve is provided with visible mirror.
Above-mentioned chi batten is replaceable.
Above-mentioned roller bearing is wound with scale tape measure.
The beneficial effects of the utility model: structure is simple, cheap, be applicable to construction costs drawing computational engineering amount measures use; Product design is abandoned traditional triangle scale, have employed the mode of replaceable chi batten and replace.
Accompanying drawing explanation
Fig. 1 is the special drawing scale one-piece construction figure of a kind of construction costs of the utility model.
Fig. 2 is the special drawing section of structure of a kind of construction costs of the utility model.
1-chi pedestal in figure, 2-drum sleeve, 3-chi batten, 4-roller, 5-visible mirror, 6-roller bearing, 7-protractor.
Embodiment
Below in conjunction with accompanying drawing 1-2, embodiment of the present utility model is made a detailed explanation.
Embodiment: the drawing scale that a kind of construction costs is special, its major constituents has: chi pedestal 1, drum sleeve 2, chi batten 3, roller 4, visible mirror 5, roller bearing 6, protractor 7, described chi pedestal 1 has gripped chi batten 3, described chi pedestal 1 side is drum sleeve 2, the built-in roller bearing 6 of drum sleeve 2, roller bearing 6 liang of ends are provided with roller 4;
In described chi pedestal 1, middle section position is provided with protractor 7;
Described drum sleeve 2 is provided with visible mirror 5.
Described chi batten 3 is replaceable.
Described roller bearing 6 is wound with scale tape measure.
The utility model have employed the integration of module, it is achieved that a functional lifting, because traditional triangle scale is present in two drawbacks, the first has three angles, the thing that angle is sharp-pointed easily runs into people, and it two is exactly ratio only three kinds, sometimes can not meet the needs of practical application; The problems referred to above are just well avoided in the exploitation of this product.
Specifically say: it one is advanced by the rolling of roller 4 on drawing, and the distance numeral of rolling may be displayed on visible mirror 5, and the mode that this kind measures drawing is applicable to big drawing; It two is exactly that multiple ratio is arbitrarily changed, according to the reality of drawing, it is possible to changed by the chi batten 3 detached on chi pedestal 1. Therefore the design's product is not by the restriction of proportion requirement.
Claims (3)
1. the drawing scale that a construction costs is special, its major constituents has: chi pedestal (1), drum sleeve (2), chi batten (3), roller (4), visible mirror (5), roller bearing (6), protractor (7), it is characterized in that: chi pedestal (1) has gripped chi batten (3), described chi pedestal (1) side is drum sleeve (2), drum sleeve (2) built-in roller bearing (6), roller bearing (6) two end is provided with roller (4);
Described chi pedestal (1) interior middle section position is provided with protractor (7);
Described drum sleeve (2) is provided with visible mirror (5).
2. the drawing scale that a kind of construction costs according to claim 1 is special, it is characterised in that described chi batten (3) is replaceable.
3. the drawing scale that a kind of construction costs according to claim 1 is special, it is characterised in that be wound with scale tape measure on described roller bearing (6).
