Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, it is described be the explanation to the utility model and
It is not to limit.
As shown in Figure 1, a kind of device for measuring downhole orientation orifice angle, including feeler lever 1 and for showing measurement angle
Scale dial plate 2.
Wherein, scale dial plate 2 is semicircle dial plate, and angle index, measurement range are provided on the surface of scale dial plate 2
It is 0 °~180 °.Center symmetric setting of the angle index along scale dial plate, the center line overlap of 0 graduation mark and semicircle dial plate,
Angle index along the circumferential direction extends to 90 ° to two sides centered on 0 graduation mark.Semicircle cunning is additionally provided on scale dial plate 2
Slot, the center of sliding slot and the center of scale dial plate 2 are concentric.
Mounting hole is arranged in the center of scale dial plate 2, and the middle part of feeler lever 1 is connect by fastener 3 with mounting hole, and feeler lever
1 can be rotated centered on fastener 3, carry out angle measurement.
As shown in Fig. 2, as one embodiment, in order to guarantee the accuracy of measurement, while existing convenient for observation feeler lever end
Direction on scale dial plate 2 should make feeler lever 1 and 2 keeping parallelism of scale dial plate, therefore circular arc type is arranged on scale dial plate 2
Sliding slot, the center of sliding slot and scale dial plate 2 are concentric, bolt 4 are arranged in the end vertical of feeler lever 1, bolt 4 passes through sliding slot, passes through
Nut 5 connect the end of feeler lever 1 with sliding slot, and the diameter of nut is greater than the width of sliding slot, in measurement process, the end of feeler lever 1
