Abstract
The utility model relates to a safety ruler, belongs to mapping and measuring tools, and mainly solves the problem that a conventional ruler is prone to breaking and abrasion on scales. The safety ruler comprises a ruler body, and is characterized in that a transparent explosion-proof film is arranged on the surface of one side, with scales, of the ruler body, and a round suspension hole are respectively reserved at the edge of the ruler body as well as a corresponding position on the explosion-proof film. The scales on the safety ruler can be avoided from being abraded and can be kept clear, breaking of the safety ruler can be reduced, service life of the safety ruler is greatly prolonged; meanwhile, when the safety ruler is broken accidently, the explosion-proof film can bond the breaking positions to prevent a broken ruler or sharp broken positions from splashing to injure people; via the suspension holes, the safety ruler can be hung on one side of the desk or on the wall when not used.
Description
Technical field
The utility model relates to a kind of drawing, survey tool, specifically is a kind of safe ruler.
Background technology
In daily study, work and the life, run into the situation of measurement, setting-out, drawing through regular meeting, for guaranteeing shape, dimensional standard, standard, need be by instruments such as ruler, set squares, the tradition ruler adopts transparent sheet plastic to be made, the wearing and tearing easily of graduation mark part, definition descend and can influence use; In addition, because the fragile frangibility of selected materials, fracture place sharp-pointed on the plastic sheet that splashes after the ruler accident fractures also causes casualty accident easily, has certain potential safety hazard.And existing ruler is inconvenient to hang, though set square inside has the hole, boring ratio is bigger, bumps easily during suspension.
The utility model content
The purpose of this utility model is to provide a kind of safe ruler, and this ruler can effectively prevent the graduation mark wearing and tearing, the convenient suspension, and have the function that is difficult for hurting sb.'s feelings after ruler fractures.
The technical scheme in the invention for solving the technical problem is: a kind of safe ruler, comprise the ruler body, it is characterized in that, described ruler body has on the side surface of graduation mark and posts transparent rupture pressure disc, the edge of described ruler body is provided with circular suppending hole, and the relevant position of described rupture pressure disc also is provided with circular suppending hole.
The beneficial effects of the utility model are: rupture pressure disc can be avoided the wearing and tearing of ruler graduation mark, effectively keep scale clear, also can reduce and fracture, prolonged the service life of ruler greatly, simultaneously, when ruler accident occurs and fractures, but the position of rupture pressure disc adhesion fracture prevents that the disconnected chi that splashes or sharp-pointed fracture position from hurting sb.'s feelings; Suppending hole can be suspended on ruler on one side or wall of desk when not using.The utility model is simple in structure, and use, easy-to-operate do not take up room.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 ruler body, 2 rupture pressure discs, 3 suppending holes.
The specific embodiment
As shown in Figure 1.A kind of safe ruler, comprise ruler body 1, described ruler body 1 is the set square type for to have the laminar of graduation mark, rupture pressure disc 2 is shape and the on all four transparent membrane that has gum of ruler body 1 shape, and rupture pressure disc 2 is attached on the side surface that has graduation mark on the ruler body 1; The edge of described ruler body 1 is provided with circular suppending hole 3, and the opposite position of described rupture pressure disc 2 also is provided with circular suppending hole.
Rupture pressure disc can be avoided the wearing and tearing of ruler graduation mark, effectively keeps scale clear, also can reduce fractureing, prolonged the service life of ruler greatly, simultaneously, when ruler accident occurs and fractures, but the position of rupture pressure disc adhesion fracture prevents that the disconnected chi that splashes or sharp-pointed fracture position from hurting sb.'s feelings; Suppending hole can be suspended on ruler on desk or the wall when not using.
