Abstract

A new movably-folding square, belonging to the stationary supplies, comprises a guide-ruler part, a work-ruler part and a screw nut. The guide-ruler part is provided with an L-shaped guide-fixing chute, and the work-ruler part comprises a slide block, a joint ruler and a work-calibration side. With simple structure, convenient use, folding collection, accurate locating and strong adaptability, the new movably-folding square can be used both in offices and unprofessional drawing offices, the working efficiency of drawing and table-making being improved, providing wide-range application.

Description

The movable square of a kind of novel foldable

Affiliated technical field the invention belongs to drawing tool, and promptly square is a kind of novel T-square.

Background technology up to now, existing T-square generally is made up of two orthogonal limits, one is guide edge, one is working edge, working edge is fixed on guide edge, and scale is arranged on the working edge.Its weak point mainly shows: 1. its both sides maintain static, and both sides are not in a plane; 2. require the chart board of mapping to have the limit of straight line to slide for guide edge when work, this has just limited it and can only better use on draughting board; 3 because influence mapping effect not in a plane, is made troubles on two limits so give when mapping in a plane.4 working edges are to slide with guide edge, though working edge has scale, guide edge is to slide along a limit of chart board, does not generally have scale, and this makes troubles with regard to giving the location of working edge when sliding up and down; At last,, cannot fold, make its appearance and size very big, be inconvenient to carry because it is that both sides are relatively-stationary.

Summary of the invention the objective of the invention is at above-mentioned weak point, and it is strong to design a kind of applicability, easy to operate, the novel T-square of accurate positioning.

For achieving the above object, can realize by following measure: this collapsible movable square comprises work rest blade part, work chi part and a degree of tightness nut composition.Fixed guide groove [1] and scale limit [5], location are arranged on the work rest blade part, and gathering sill [1] is divided into chute A-B (the A-B section is that the A point is high, and the B point hangs down oblique chute) and chute B-C (being horizontal concrete chute) here; Work chi part then is made up of work chi [7], connection chi [4] and the slide block [3] on band scale limit [6].Slide block [3] chute [1] that slides through between work rest blade part and the work chi part is realized sliding, and uses a degree of tightness nut [2] to realize degree of tightness at last.

Description of drawings is below in conjunction with description of drawings one embodiment of the present of invention.

Accompanying drawing 1 is a structural principle schematic diagram of the present invention.

1. gathering sills among the figure, 2. degree of tightness nut, 3. slide block, 4. connection chi, 5. work rest blade scale limit, 6. work chi scale limit, 7. work chi.

The specific embodiment is shown in Figure 1, and this collapsible movable square comprises work rest blade part and work chi part.Owing to adopt round slider, only the work chi need be revolved in use and turn 90 degrees, and can be vertical with work rest blade, the chi [7] of will working pushes inward, allow sliding fast [3] to enter the B-C section along the A-B section, the chi [7] of working simultaneously descends with the contact edge that is connected chi [4] and just in time snaps on the work rest blade scale limit [5], and guarantees in a plane.Like this, work chi part just not only can accurately be slided along fixed guide groove [1], and uses and also need not be confined to use on drawing board, can be used on the general table of office more convenient mapping and do form.

Owing to adopted degree of tightness nut [2], made mobile more convenient; Can collect by rotary folding simultaneously, be convenient for carrying.

Its manufacture method, at first can first-selected stainless steel or other all kinds of high-quality section bars as material, make in proportion according to schematic diagram of the present utility model.When making, the work chi should connect thick many of chi, and connects together, and guarantees that two parts are in conjunction with closely.

Be exactly that this square can be made reduced size as general small-sized stationery use in addition.

Claims (6)

1. the movable square of novel foldable comprises the fixed guide chi, and the active operation chi is characterized in that having on the work rest blade L shaped gathering sill and a scale limit, has slide block and degree of tightness nut can rotate folding storage on the work chi.

2. collapsible movable square according to claim 1 is characterized in that gathering sill is arranged on work rest blade.

3. collapsible movable square according to claim 1 is characterized in that having a location graduation mark on work rest blade.

4. collapsible movable square according to claim 1, it is characterized in that having on the work chi can movable slide block and degree of tightness nut.

5. collapsible movable square according to claim 1 is characterized in that the transition portion of connection chi on the work chi and working portion can just snap on the graduation mark limit, location of fixed guide chi in the time of work.

6. according to claim 1,2,3,4, or 5 said collapsible movable squares, it is characterized in that can sliding relatively between work chi and the work rest blade and accurate location.
