The utility model discloses simple structure, can measure width, length, degree of depth, use, convenient to carry are fit for middle and primary school student and use.

Description

Multi-functional ruler

Technical field

The utility model relates to a kind of student and uses measurer, belongs to the stationery field.

Background technology

At present, the ruler that the student uses on the market includes the chi body, and the chi body is provided with scale, and this chi can be measured length, but very inconvenient when the tolerance width and the degree of depth, does not also have the student that can measure the width and the degree of depth easily to use ruler at present; We also know has slide measure can measure height, width, and the precision height, but its price height measure inconvenience, and often the student does not need too high accuracy with ruler yet, uses so trip table slide calliper rule incompatibility regular primary and secondary schools give birth to.

The utility model content

The utility model purpose provides a kind of simple in structure, is fit to the multi-functional ruler that the student uses.

The utility model ground purpose is achieved in that a kind of multi-functional ruler, comprise chi body, width tolerance bar and depth measure bar, described chi body is provided with scale, width tolerance boom end is fixed with the chi head, described chi head matches with chi body end face, the chi body is provided with the chute that matches with width tolerance bar and depth measure bar respectively, and width tolerance bar and depth measure bar are arranged in the chute, and described width tolerance bar and depth measure bar are provided with scale.

In use, scale on the chi body keeps the original function of ruler in the prior art, when needs are measured the width of object, pull out width tolerance bar along the chute direction, institute is surveyed object to be stuck between chi head and the chi body end face, read the scale on the pairing width tolerance of the chi body end face bar, this scale is the pairing size of width of the object of surveying.Correspondingly, pull out the depth measure bar, can measure the object degree of depth; The utility model is simple in structure, can measure width, length, the degree of depth, and use, easy to carry is fit to students in middle and primary schools and uses.

As further improvement of the utility model, the chi body under the chute is provided with locating slot, is fixed with dog screw respectively on depth measure bar and the width tolerance bar, and the end of described dog screw is stretched in the locating slot.This technical scheme can only be moved dog screw in locating slot, can prevent width tolerance bar and the slippage from chute of depth measure bar in measuring process; On the other hand, when measurement needs, dog screw can be locked, the dog screw end is pressed on the chi body of locating slot bottom, at this moment, corresponding width tolerance bar or depth measure bar can not move, and play the effect of memory or default scale.

Chute on the chi body can be dovetail groove or dovetail groove.Such groove is easy to process, and is simple in structure, and cost is low.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is that A-A among Fig. 1 is to view.

1 chi head, 2 chi bodies, 3 width tolerance bar, 4 depth measure bars, 5 trapezoidal chutes, 6 dog screws, 7 locating slots.

The specific embodiment

As figure, multi-functional ruler mainly is made up of chi body 2, width tolerance bar 3 and depth measure bar 4, chi body 2 is provided with scale, width tolerance bar 3 ends are fixed with chi head 1, described chi head 1 matches with the end face of chi body 2, chi body 2 is provided with the trapezoidal chute 5 that matches with width tolerance bar 3 and depth measure bar 4 respectively, and width tolerance bar 3 and depth measure bar 4 are arranged in the trapezoidal chute 5, and described width tolerance bar 3 and depth measure bar 4 are provided with the scale that begins from rod end; Chi body 2 under the described trapezoidal chute 5 is provided with locating slot 7, is fixed with dog screw 6 respectively on depth measure bar 3 and the width tolerance bar 4, and the end of described dog screw 6 is stretched in the locating slot 7.

The utility model is not limited to the foregoing description, and the upper trapezoid groove of above-mentioned chi body also can be dovetail groove; Described width tolerance bar and depth measure bar also can be arranged in parallel.
