Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The foldable movable rule as shown in fig. 1-3 comprises a main rule 1 and an auxiliary rule 2, wherein a flange 11 is arranged at one end of the main rule 1, the auxiliary rule 2 is connected with the main rule 1 through a connecting rod 3, the connecting rod 3 comprises a fixed rod 31 and a movable rod 32, the fixed rod 31 is fixed on the flange 11, the movable rod 32 is rotationally connected with one end of the auxiliary rule 2, the movable rod 32 is inserted into the fixed rod 31, the inserted position of the movable rod 32 and the fixed rod 31 is connected through a spring 33, the auxiliary rule 2 can be horizontally and vertically abutted with the main rule 1 through the rotation of the movable rod 32, the main rule 1 is flush with the bottom surface of the auxiliary rule 2, when the main rule 1 is horizontally abutted with the auxiliary rule 2, the main rule 1 is flush with the front and rear outer surfaces of the auxiliary rule 2, and when the main rule 1 is vertically abutted with the auxiliary rule 2, the main rule 1 is flush with the front and rear outer surfaces of the auxiliary rule 2.
As a preferred embodiment, the main scale 1 is provided with a handle 12, and the handle 12 is convenient for holding and lifting the scale bar on the blackboard surface during line drawing and drawing.
As a preferred embodiment, the free ends of the main ruler 1 and the auxiliary ruler 2 are correspondingly provided with a magnetic layer 4 capable of being magnetically attracted, and the magnetic layer 4 can be magnetically attracted with the main ruler 1 after the auxiliary ruler 2 is folded and contracted by rotation, so that the portable ruler is convenient to carry.
The foldable movable ruler provided by the utility model consists of the main ruler 1 and the auxiliary ruler 2, can be folded and contracted when being carried, and can be rotated and unfolded according to the requirement when being used, so that the two can be horizontally or vertically butted, and the line drawing requirement when drawing is met.
When in carrying, the auxiliary ruler 2 corresponds to the main ruler 1 and is contracted and placed at the rear side of the main ruler 1, thereby being convenient to carry. When the blackboard is used, the auxiliary ruler 2 can be unfolded and butted with the main ruler 1, so that the line drawing operation on the blackboard surface is performed.
The auxiliary ruler 2 is pulled backwards so as to be separated from the main ruler 1 forwards and backwards, and therefore the auxiliary ruler 2 can be adjusted in a free rotation mode. When the auxiliary ruler 2 is turned to a horizontal state, the auxiliary ruler 2 can be contracted under the action of the spring 33, so that the auxiliary ruler 2 is horizontally butted with the main ruler 1 to form an lengthened ruler strip whole.
Correspondingly, the auxiliary ruler 2 is rotated by 90 degrees in the same way, so that the auxiliary ruler 2 is vertically butted with the main ruler 1 to form a right angle ruler for line drawing.
The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
