Abstract

The utility model discloses a multi-use measuring ruler. The multi-use measuring rule is provided with two ruler rods which are like a divider. One end of a graduation ruler which is transversely arranged between the two ruler rods and whose upper surface are marked with length reticles and angle reticles is connected with a main ruler rod, and the other end of the graduation ruler is placed on the sheave of a bracket on the other main ruler rod. The graduation follows the rotation of the main ruler rods to slide inside the sheave. The read number of the length reticle of the length between measuring heads on two ends of a measuring ruler rod reflected onto the graduation ruler is a measured length. The two ruler rods form an angle which is overlapped on a measured angle. The read number of the angle reticle reflected onto the graduation ruler is a measured angle.

Description

Multi-use Measuring rule

The utility model relates to a kind of comprehensive dip stick that can measure certain-length and angle easily, and it can also be as divider, the use of planing.

In the existing survey instrument, measure the ordinary measring tool of length and angle, all be separately to use, often running in routine duties not only needs to measure the length while but also needs to take measurement of an angle, this just needs a length chi and angulometer, if will need segmentation again or make an arc, draw garden etc., that just also needs divider and instrument such as plan.It is just inconvenient to work together like this.When especially current public security department reconnoitres the scene and measures footwork, need often to measure length and angle, but currently also do not use comprehensive dip stick, it is very inconvenient to work together.

Task of the present utility model is the simple and easy quick survey instrument that a kind of multi-purpose will be provided, it can measure certain-length and angle rapidly easily, can also be as planing and the divider use, remote walking is carried and can also be done the walking stick use, this chi is particularly suitable for public security department and reconnoitres the scene, comprehensive uses such as footwork measurement.

Task of the present utility model is finished as follows: can make different size according to measurement range needs ruler, bigger ruler chi bar also can make pull and convertible, more than two joints or two save, when measuring length rule opened in the groove that lower limb is placed on the support sheave, make the pointed gauge head of two pairs of chi bar lower ends aim at tested length, observe a calibration indicator sign note of rotating primary division rod side, length number of division on the indicated rule of this mark, be exactly the length of measured object, but continuous coverage.According to the proportional principle of similar triangles corresponding sides, length between two gauge heads, all corresponding is reflected on the rule that lies across on the primary division rod, take measurement of an angle: the rotation axis of open dip stick primary division rod is placed on the summit of measured angle, the center line of dip stick bar or two corresponding crest lines of two chi bars are overlapped in respectively on two limits of measured angle, calibration indicator sign on the observation main scale face is remembered the angle number on the indicated rule, the angle that will survey exactly, but continuous coverage.Segmentation and the method for making an arc, drawing the garden are with to use divider usually the same with the method for planing.

Below with reference to accompanying drawing invention is described in further detail.

Is the measuring head (1) of HRC48-52 has the plating of chute (22) in the centre with rivet (2) riveting two pairs of chi bars of channel-section steel (3) one ends (other material such as pair chi and main scale available copper, aluminium, steel, duroplasts) with reference to two of Fig. 1 through Quenching Treatment hardness, a bolt compact heap (5) that is connected with primary division rod (4a) (4b) is arranged respectively in the middle chute of two pairs of chi bars (3), by the wing nut on compact heap (5) bolt can with pay chi (3) respectively and main scale (4a) (4b) tighten together.The screw rod of the compact heap (5) on the primary division rod (4b) also plays an effect here and will pay chi bar (3) exactly and pull out the longest position-limiting action.Fixedly screw (14) screw (14) one ends and the rule riveting of the band wing nut of rule (8) are one to have one on the top of the close compact heap (5) of primary division rod (4a), shank of screw is fixed by wing nut and primary division rod, and it is rotatable arbitrarily angled to unclamp the wing nut rule.Screw (14) also plays one pair of chi bar (3) here and pulls out the longest position-limiting action.There are two kinds of scales in rule (8) front, with reference to Fig. 3, top scale mark is to be datum line with primary division rod (4b) outer edge line, marks with graphing method according to the proportional principle of similar triangles corresponding sides.Rule bearing support (6) is being arranged with reference to Fig. 2 on primary division rod (4b) lateral surface and on the corresponding position of gib screw (14) of rule (8), support (6) uses rivet (16) riveting on main scale (4b) lateral wall, half dollar head screw (18) is fixed on copper sheave (17) on the support (6), adjust degree of tightness with nut (19), copper wheel (17) can be rotated flexibly be as the criterion.Also with reference to Fig. 1, during measurement rule (8) feather edge is placed in the groove of copper sheave (17), in primary division rod (4b) lateral surface rule top two kinds of scale mark cue marks (not drawing among the figure) are arranged, a kind of sensing length scale mark, a kind of orientation angle scale mark, primary division rod (4b) and primary division rod (4a) can be fixed the position of two primary division rods by wing nut (7).Have one with screw (10) cushion block (12) contiguous block (9) and primary division rod (4a) to be fixed together in primary division rod (4b) top, on contiguous block (9), be equipped with one and locate the opening angle that screw (13) (not drawing among the figure) limits two main scales with the cushion block (12) of the identical material of bar.Bakelite handle (11) is spun on the bolt of contiguous block.

During measurement, pull out two pairs of chis (3) two measuring heads (1) and must move to greatest extent fixingly, otherwise influence measuring accuracy.Primary division rod (4a) (4b) and two pairs of chi bars (3) glade plane space are as far as possible little, otherwise also influence measuring accuracy.

During operation: measure length, two pairs of chis (3) are moved to use compact heap (5) fixing to greatest extent, two measuring heads (1) are aimed at tested length, by the number of division on the rule (8) of cue mark (20) indication, are exactly measured length.Take measurement of an angle: primary division rod axle (7) is placed on the measured angle summit, two limits that the center line or the corresponding sides crest line of two primary division rods (4a) (4b) is overlapped in measured angle, by the angle index number on the rule (8) of cue mark (21) indication, be exactly tested angle.
