Abstract
The utility model relates to a novel lattice rule, which belongs to the technical field of the group of straight rulers of the subclass of writing or drawing supplies; writing or drawing auxiliary supplies of the class of writing or drawing appliances; office supplies under the subsection of printing in the section of performing operations and transporting according to the International Patent Classification (IPC). The number is B43L7/00. The utility model is composed of a rule body, a dovetail rail, a sliding plate and a washer. The utility model is characterized in that the sliding plate is arranged on the dovetail rail of the rule body, and the positioning accuracy of the rule is improved. The utility model is a novel lattice rule with practical value.
Description
The utility model relates to a kind of novel lattice chi.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, ruler technical group field.Be numbered B43L 7/00.
At present, the demand about the technology plaid matching chi of ruler existing and that once had was all done very fruitful effort, also once designed many outstanding technical schemes.As being declared by Lin Guixiang of the Decree of Patent Office of China in 1996, Granted publication number is CN2216468Y, and China Patent No. (ZL) is: No. 95208911.4 utility model title is the utility model patent of " line drawing ruler automatically ", the technical scheme that is adopted.At the ruler technical elements is a routine of great value invention, and it has solved the problem that can draw straight line automatically that carries on the chi of utilizing effectively.But still have some deficits, it also is difficult to solve the problem that ruler can move along drawn rectilinear direction exactly.
The purpose of this utility model is to provide a kind of novel lattice chi.To solve the problem that ruler can move along drawn rectilinear direction exactly.
The purpose of this utility model is achieved in that a kind of novel lattice chi of this utility model.Mainly constitute by blade, swallowtail track, slide plate, pad.Its critical part blade, swallowtail track, slide plate are made with the hard plastic material injection moulding.Pad is made with flexible glue.In the utility model, blade and swallowtail track are connected in one, in injection moulding process, in same procedure, make, slide plate is injection molded separately, pad is to form with the cushion compound cutting, pad is sticked on the slide plate, afterwards slide plate is installed on the swallowtail track in the blade, after this just can directly use this utility model.So just realized the purpose of this utility model.
The technology of the utility model and original ruler has been compared three advantages and improvement;
The first, because the utility model has designed the application of swallowtail track in technical scheme,, blade saves materials thereby can being shortened;
The second and since the utility model in technical scheme, designed slide plate and swallowtail track be used blade to move horizontally precision higher;
The 3rd, use and slide plate to be skidded behind the flexible glue on paper to cause error owing to the utility model has designed pad in technical scheme.Thereby just can more effectively solve the problem that ruler can move along drawn rectilinear direction exactly.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the chi body Facad structure synoptic diagram of a kind of novel lattice chi of the utility model:
Fig. 2 is the chi body bottom surface structural representation of a kind of novel lattice chi of the utility model:
Fig. 3 is the chi body section structural representation of a kind of novel lattice chi of the utility model:
The numbering of parts explanation in the synoptic diagram: (1) blade (2) swallowtail track (3) slide plate (4) pad
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of novel lattice chi of the present utility model.Mainly constitute by blade (1), swallowtail track (2), slide plate (3), pad (4).Its critical part blade (1), swallowtail track (2), slide plate (3) are made with the hard plastic material injection moulding.Pad (4) is made with flexible glue.In the utility model, blade (1) is connected in one with swallowtail track (2), in injection moulding process, in same procedure, make, slide plate (3) is injection molded separately, pad (4) is to form with the cushion compound cutting, pad (4) is sticked on the slide plate (3), afterwards slide plate (3) is installed on the swallowtail track (2) in the blade (1), after this just can directly use this utility model.So just realized the purpose of this utility model.Thereby just can solve the problem that ruler can move along drawn rectilinear direction exactly.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, if when drawing straight line, straight length exceeds the length of blade (1), if general ruler, the straight line portion of then mending picture behind mobile ruler again is easy to the off-straight direction, if utilize the utility model, then can direct mobile blade (1), blade (1) will move along former wired direction under the direction positioning action of slide plate (3) and swallowtail track (2) more accurately, thereby guarantee the quality of drawing.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with the duroplasts, utilize the basic equipment of injection moulding factory, take assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
Claims (3)
1. novel lattice chi, it mainly is to be made of blade (1), swallowtail track (2), slide plate (3), pad (4), it is characterized in that swallowtail track (2) is connected in the blade (1).
2. kind one novel lattice chi according to claim 1 is characterized in that the high precision between slide plate (3) and the swallowtail track (2) connects.
3. a kind of novel lattice chi according to claim 1 is characterized in that pad (4) is gluing on slide plate (3).
