Abstract
The utility model relates to a tree trunk diameter quick measurer, particularly to an open-close angle square. A graduated scale (2) is connected with a scale channel plate (7) via a rotating shaft (5). The pen-close angle square can be freely opened and closed; a double position pin (8) is connected with an angle fixing hole (6) in order to determine the included angle of the angle square and improve the stability of the angle square. A microcomputer can be installed on the graduated scale (2); the microcomputer can automatically display the numerical value of trunk diameters, and store and process the data of measured trunk diameters. The utility model can be operated by single hand, and the utility model has direct observation and measurement. Therefore, the utility model can greatly enhance the efficiency and the accuracy for measuring diameters.
Description
The utility model relates to a kind of measurer, and outstanding tool relates to a kind of folding angle square of measuring trunk diameter.
Measure now trunk diameter caliper commonly used caliper scale arranged, enclose chi, ruler, Finland's trisquare and Japanese trisquare etc. are also arranged.Their weak point is: operation inconvenience causes malobservation easily.
The purpose of this utility model is, designs a kind of both simple to operate easy to carryly, can observe accurate folding angle square again.
The utility model is achieved in that this angle square mainly is made up of rule (2) and chi frid (7), and links together by rotating shaft (5).Can also link by free folding angle, to determine the angle of angle square, the raising degree of stability with dibit pin (8) and Ding Jiao hole (6).Flute profile and size in the chi frid (7) are identical with rule (2).Rule (2) can be incorporated in the groove.Rule (2) and chi frid (7) away from rotating shaft (5) one ends one involutory chi hole (1) is arranged respectively, getting close to rotating shaft (5) one ends respectively has a Ding Jiao hole (6), dibit pin (8) can insert and close chi hole (1) or Ding Jiao hole (6).The scale value of the diameter division line (4) on the rule (2) is according to L=r/tg(α/2) demarcate.Rule (2) also can be the length transition of L electric signal, and show automatically, store and handle with the numerical value of diameter by dress micro computer (3).Can not adorn yet, observe with eyes.
Good effect of the present utility model is that (1) utilizes angle and the long amplification ratio of determining that improves of chi, the dried diameter of accurate ground velocity assize so its energy is easy because of it.(2) can improve accuracy of observation, because one is the incircle of 2 α at angle, diameter is d, between the length of side L that push up to the angle at its radius r and point of contact, exist L=r/tg(α/2) funtcional relationship, so as 2 α fixedly the time, along with the variation of r, must there be a definite L corresponding with it, thereby can expresses r or d by L.When α/2＜45 °, L then〉r.When α＜26.565 °, inevitable L〉2r〉d, promptly improve amplification ratio, that is enlarged scale spacing, will improve so on length of side L, express the graduation precision of the scale mark of inscribe garden diameter d, also just improved the observation precision.
Fig. 1 is a basic block diagram of the present utility model.
When assize, extract dibit pin (8) and open angle square as shown in Figure 1, again dibit pin (8) is inserted in the pilot hole (6), firmly determine the angle of angle square, increase degree of stability.Then angle square is blocked the position of the section (9) of trunk to be measured.When angle square two inboards are tangent with section (9), can be at place, point of contact observation trunk diameter numerical value.Also can place the place, point of contact to the pointer of micro computer (3), show, store, handle the trunk diameter numerical value of surveying automatically.So measure by strain, simple and convenient.Observation finishes, and extracts dibit pin (8) and shares angle square, dibit pin (8) is inserted close chi hole (1) again.Obviously close behind the chi easy to carryly, chi frid (7) has also just been protected rule (2) and micro computer simultaneously.
Claims (4)
1, a kind of trunk diameter rapidly measuring device-folding angle square, it comprises rule (2) rotating shaft (5), it is characterized in that it also comprises can link to each other by rotating shaft (5) with chi frid (7), can also be connected with Ding Jiao hole (6) by free folding angle with dibit pin (8), to determine the angle of angle square, improve degree of stability.
2, folding angle square according to claim 1 is characterized in that: the scale value of the diameter division line (4) on the rule (2) is according to L=r/tg(α/2) demarcate.
3, folding angle square according to claim 1 is characterized in that: micro computer (3) can be installed on the rule (2) can show the numerical value of trunk diameter automatically and do storage and processing, also can not adorn, observe with eyes.Also can place the place, point of contact to the pointer of micro computer.
4, folding angle square according to claim 1, it is characterized in that: the flute profile in the chi frid (7) is identical with rule (2) with size, rule can be incorporated in the groove, rule (2) respectively has an involutory chi hole (1) with chi frid (7) away from rotating shaft (5) one ends, getting close to rotating shaft (5) one ends respectively has a Ding Jiao hole (6), and dibit pin (8) can insert and close chi hole (1) or Ding Jiao hole (6).
