Abstract
The utility model relates to a volume measuring caliper used for measuring and calculating the diameter and the volume of various logs and bamboo woods. The utility model is characterized in that the volume measuring caliper is composed of two bow-shaped ruler sheets (1) (2) which are combined together through a hinged shaft, wherein, the handle part of the ruler sheet (2) is provided with an arc-shaped ruler board with scales (5); the handle part of the other ruler sheet (1) is provided with a scale pointer (4) and a positioning handle (3). The utility model has the advantages that the volume measuring caliper overcomes the defect that a measuring tape has fussy measurement, large estimation error, etc.; the volume measuring caliper provides a measuring tool with simple operation, and visual and accurate measuring conversion for forest employees.
Description
The utility model relates to a kind of measuring appliance, particularly a kind of volume of timber measurement slide calliper rule that are used for all kinds of round logs, bamboo wood are carried out diameter, volume of timber measuring and calculating.
Bamboo and wood in forest farm, the bamboo plantation is in growth, need often carry out the measurement estimation of diameter, girth, area and the volume of timber in order to carry out scientific research and the yield by estimation, and traditional measuring method is calculated, tables look-up, is converted after being mostly to adopt the tape measuring girth, this measuring method is not only time-consuming, and its accuracy is also relatively poor.
The purpose of this utility model provides a kind of easy to use, quick with regard to being to overcome above-mentioned weak point of the prior art, measures the slide calliper rule of volume of timber measurement accurately.
The purpose of this utility model can adopt following measure to realize:
The volume of timber of the present utility model is measured slide calliper rule and is made up of two arc chi sheets that combine by hinge; The shank of one of them chi sheet is provided with the arc chi plate of a band scale, and the shank of another chi sheet is provided with tuning drive gear and position fixing knob.
Be carved with diameter, girth and area, volume of timber conversion scale on the arc chi plate in the utility model.Be carved with diameter, girth scale on the front of its arc chi plate, be carved with at its back side and diameter, the corresponding area of girth scale, volume of timber conversion scale.
Advantage of the present utility model is: overcome and used the loaded down with trivial details of tape measuring in the prior art, the weak point of the big grade of estimation error for the forestry worker provides a kind of easy and simple to handle, is measured the intuitive and accurate survey instrument that converts.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the front view of the utility model under user mode.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in Figure 1 and Figure 2, measurement slide calliper rule of the present utility model are made up of two arc chi sheets (1) (2) that combine by hinge; The shank of one of them chi sheet (2) is provided with the arc chi plate of a band scale (5), be carved with diameter, girth scale on the front of arc chi plate, be carved with at its back side with diameter, the corresponding area of girth scale, volume of timber conversion scale and (when producing this product, also required scale can be set on the chi plate according to actual needs, as shouldn't girth, the area scale, add volume of timber scale at tow sides); The shank of another chi sheet (1) is provided with tuning drive gear (4) and position fixing knob (3).
When using slide calliper rule of the present utility model as using scissors, finger is stretched in the shaking hands of two chi handles, the cutting edge of slide calliper rule is opened, forest or bamboo in the face of growth, block diameter, when degree of tightness is suitable, with position fixing knob under the finger plate, make two chi sheet relative positionings, can read diameter, girth, area and the volume of timber of measured object by pointer.
Claims (3)
