Abstract
The utility model relates to a multi-functional measuring instrument, in particular to a measuring instrument which is mainly used for measuring the radius of the incomplete arc. The multi-functional measuring instrument comprises a frame body, a cross rod, a vertical rod and a digital display screen and is characterized in that the cross rod is a two-stage synchronous reversal extension device and is connected with the frame body in a sliding way; the vertical rod is vertical to the cross rod and connected with the frame body in a sliding way; the two ends of the cross rod respectively extend downward and are provided with a measuring rod respectively; and the digital display screen is fixed on the surface of the frame body. The multi-functional measuring instrument has novel design and simple structure, can carry out precise measurement to the radius of the incomplete arc conveniently, fast and accurately and also can measure the width or the depth of the devices.
Description
Technical field
The utility model relates to a kind of surveying instrument, particularly a kind of measuring instrument of measuring imperfect arc radius that is mainly used in.
Background technology
In machining, to the measurement of non-complete arc radius, generally be to measure to try to achieve after certain some size is calculated again, not only measuring error is big, and calculates loaded down with trivial detailsly, can not adapt to modern production and precision machined demand.
The utility model content
The technical problems to be solved in the utility model is: a kind of measuring instrument that can measure imperfect arc radius comparatively accurately is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of digital display radius chi that holds the grid measuring system that adopts, comprise framework, cross bar, montant and show the number screen, wherein cross bar is a two-part synchronous backward retractor device, cross bar and framework are slidingly connected, montant is slidingly connected perpendicular to cross bar and with framework, cross bar two ends extension downwards respectively respectively are provided with a sounding rod, show the number screen and are fixed on the framework surface.Cross bar two-part synchronous backward retractor device is a hollow structure, and correspondence is provided with a tooth-arranging strip about two sections hollow spaces, and the centre is equipped with and the tooth bar meshed gears.
For serviceable life of prolonging dip stick and widen range of application, measuring head is set to detachable the replacing further, comprises that montant can extract out equally, so that renew or change the special shape measuring head.
The utility model modern design, simple in structure, very convenient, the radius to imperfect circular arc carries out precision measurement fast and accurately, the width or the degree of depth that can also measuring element.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view structural representation of the present utility model.
Fig. 2 is a left view structural representation of the present utility model
Among the figure: 1. framework, 2. cross bar, 3. montant 4. shows the number screen, 5. gear, 6. tooth bar, 7. sounding rod, 8. dismountable measuring head.
Embodiment
As shown in Figure 1, a kind of digital display radius chi that holds the grid measuring system that adopts, comprise framework 1, cross bar 2, montant 3 and show number screen 4, wherein cross bar 2 is a two-part synchronous backward retractor device, cross bar 2 is slidingly connected with framework 1, montant 3 is slidingly connected perpendicular to cross bar 2 and with framework 1, and cross bar 2 two ends extension downwards respectively respectively are provided with a sounding rod 7, shows number screen 4 and is fixed on framework 1 surface.Cross bar 2 two-part synchronous backward retractor devices are hollow structure, and correspondence is provided with a tooth-arranging strip 6 about two sections hollow spaces, and the centre is equipped with and tooth bar meshed gears 5.Sounding rod 7 is provided with dismountable measuring head 8.
School zero at first during use will be carried on the montant 3 and two sounding rods 7 close up to the centre, and two measuring heads, 8 summits are overlapped,, press width L reset button.Open cross bar, depress montant and make 3 same planes of contact of measuring head, press the height H reset button, it is 9999.99 that apparent at this moment number screen is gone up radius demonstration number, the then zero success in school.When measuring then, be opened to suitable width according to measuring the big young pathbreaker's chi of arc, montant stretched out and 3 of measuring heads are vertically acted on the circular arc, this moment, the digital display module was according to the reading H, the L that obtain, wherein H is the distance that montant moves, and L is the distance that single scale moves.The formula of deducing out according to Pythagorean theorem: R=(H
2+ L
2The automatic computing of)/2H draws the radius of circular arc and shows.
In addition, the utility model also can be used as the measuring element width, and the degree of depth of all right measuring element of montant wherein, and metric and English conversion Presentation Function is arranged.
