Abstract
The utility model relates to a multifunctional triangle, belonging to the technical field of the teaching appliance. The utility model is composed of the triangle, a compasses plate, a dividing ruler, a sliding block, a screw bolt, a nut, a fixing block and the dividing ruler. The center of the set square is provided with a circular slot for putting the compasses plate, and the edge of the compasses plate is provided with the sliding block. One side of the diameter of the compasses plate is provided with a dividing ruler slot, and the dividing ruler having a round hole is arranged in the dividing ruler slot. The dividing ruler can be moved in the compasses plate. One end of the dividing ruler is provided with a screw rod, and the other end is provided with a cap nut. The utility model has advantages of simple structure, strong practicability, convenient operation, convenient carryover and storage and multiple functions.
Description
The utility model belongs to the teaching aid technical field, is a kind of multi-functional triangular ruler.
Set square, compasses, protractor are three kinds of drawing instruments of different purposes, need three kinds of instruments to have during drawing, and be very inconvenient during use.
The purpose of this utility model provide a kind of simple in structure, practical, easy to use, multi-functional triangular ruler.
The purpose of this utility model is achieved in that it is made up of set square, compasses plate, rule, slide block, screw rod, nut, fixed block, rule, there is the circular groove of putting the compasses plate at the center of set square, the compasses panel edges has the slide block that is connected with the set square dovetail groove more than two, fix with slide block between compasses plate and the set square, the compasses plate directly has the rule groove through a side, be placed with the rule of band circular hole in the rule groove, the fixed block bonding with the rule groove arranged below the rule groove, rule one end has screw rod, screw rod one end is fixed with fixed block, and the other end has nut.
The utility model has the advantages that, simple in structure, practical, easy to use, be easy to carry, preservation and function be many.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a planar structure schematic diagram of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1 of the present utility model.
Fig. 3 is the B-B cutaway view of Fig. 1 of the present utility model.
Number in the figure is described as follows: 1, set square, 2, the compasses plate, 3, rule, 4, slide block, 5, screw rod, 6, nut, 7, fixed block, 8, the hole, 9, fixed block, 10, screw slot.
As shown in the figure, utility model is by set square 1, compasses plate 2, rule 3, slide block 4, screw rod 5, nut 6, fixed block 7,9, rule 8 is formed, there is the circular groove of putting compasses plate 2 at the center of set square 1, there is the slide block 4 that is connected with the set square dovetail groove more than two at compasses plate 2 edges, fixing between compasses plate 2 and the set square 1 with slide block 4, compasses plate 2 directly has the rule groove through a side, be placed with the rule 3 of band circular hole in the rule groove, the fixed block 9 bonding with the rule groove arranged below the rule groove, rule 3 can move in the compasses plate, rule 3 one ends have screw rod 5, screw rod 5 one ends are fixing with fixed block 7, the other end has nut 6, and rotary nut, rule 3 just can move in the compasses plate.
The circular groove at set square center can be put into the compasses plate, in order to hold and fixing compasses plate.Slide block is to be connected with dovetail groove with set square, and slide block can slide in dovetail groove, and effect is that the compasses plate on the set square can not be come off from set square.Rotary nut, the rule on the removable compasses plate needs the picture bowlder, at first fixing home position, the centre bore on the rule is aimed at graduation mark, determines the center of circle, adjust nut according to drawn radius then, pin set square, nib is inserted in the circular hole of relevant radii, revolve three-sixth turn, circle promptly is drawn as, and during the expense hornwork, outwards promotes slide block, slide block moves along dovetail groove, and the compasses plate can take off use.
