Abstract

The utility model discloses an aperture measuring rule which comprises a rule body with a handle. The rule body is of a isosceles trapezoid, guiding beads are respectively arranged in the middle portions of the two lateral sides of the rule body along the axial direction of the rule body, planes where the guiding beads are placed are vertical to the surface of the rule body, an aligning plate is sleeved on the rule body in a sliding fit manner, a locking bolt is mounted in the middle of the aligning plate, the aligning plate is vertical to the rule body, and two edges of the rule body are equipped with scales. The aperture measuring rule is reasonable in design, simple in structure and high in measuring efficiency, and can overcome the problems that a traditional vernier caliper requires measurement for several times and that a traditional plug gauge is not accurate enough in the using process.

Description

Inside diameter measurement chi

Technical field

The utility model is a kind of dip stick, and what be specifically related to is a kind of inside diameter measurement chi.

Background technology

At present, along with industrial fast development, also more and more higher to the accuracy requirement of equipment, therefore measuring aperture seems particularly important, but due to traditional vernier caliper, needs ceaselessly exploratory measurement, make measuring process not only loaded down with trivial details, and the data that record are not accurate enough.

Summary of the invention

The purpose of this utility model is to provide a kind of inside diameter measurement chi, can overcome traditional vernier caliper and need to repeatedly try the in use not accurate enough problem of precision of survey, traditional clearance gauge.

The purpose of this utility model is achieved in that a kind of inside diameter measurement chi, comprise the chi body with handle, chi body is isosceles trapezoid, the middle part, two sides of chi body is respectively along chi axon to guiding fin is being set, plane and the chi surface at guiding fin place are perpendicular, be slidably matched and be set with an alignment plate on chi body, and alignment plate middle part is installed with clamping screw, alignment plate and chi body are perpendicular, on the both sides of the edge of chi body, size scale are being set.

When the utility model is used, directly trapezoidal chi body is filled in the hole of workpiece, trapezoidal chi body must contact parallel with measured object until block, then alignment plate is slided to the parallel contact of port next and workpiece, pin clamping screw, finally catch handle that whole inside diameter measurement chi is taken out, read the scale of position, institute card division, its value is exactly pore size, disposablely can record aperture, greatly improves and measures efficiency and reduced staff's working strength.The utility model is reasonable in design, simple in structure, measures efficiency high, can overcome traditional vernier caliper and need to repeatedly try the in use not accurate enough problem of precision of survey, traditional clearance gauge.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is perspective view of the present utility model.

Fig. 2 is use status architecture schematic diagram of the present utility model.

Embodiment

A kind of inside diameter measurement chi, comprise the chi body 2 with handle 5, as shown in Figure 1 and Figure 2, chi body 2 is isosceles trapezoid, and the middle part, two sides of chi body 2 is respectively along chi axon to guiding fin 3 is being set, and the plane at guiding fin 3 places and chi body 2 surfaces are perpendicular, on chi body 2, be slidably matched and be set with an alignment plate 4, alignment plate 4 middle parts are installed with clamping screw 1, and alignment plate 4 is perpendicular with chi body 2, on the both sides of the edge of chi body 2, size scale is being set.When the utility model is used, directly trapezoidal chi body 2 is filled in the hole of workpiece 6, trapezoidal chi body must contact parallel with measured object until block, then alignment plate 4 is slided to the parallel contact of port next and workpiece 6, pin clamping screw 1, finally catch handle that whole inside diameter measurement chi is taken out, read the scale of position, institute card division, its value is exactly pore size, disposablely can record aperture, greatly improves and measures efficiency and reduced staff's working strength.
