Abstract

The utility model relates to a measuring and marking tool, particularly a vernier for measuring height. The utility model comprises a base which is provided with the basic character of a height gauge and a main gauge which is erected on the base. The vernier for measuring height is characterized in that a size marking measuring device which is composed of a shaped sliding vernier, an inverse gauge needle, a lengthening positive gauge needle, a shaped depth gauge, etc. is arranged on the main gauge. The vernier for measuring height can be used as an ordinary positive ruler needle height gauge, an inverse ruler needle height gauge and a depth gauge, and is especially suitable for the dimensional measurement of the inner side of the concave surface of complex geometric bodies. The vernier for measuring height has the advantages of reasonable design, simplicity and practicality.

Description

Multi-functional vernier height gauge.

The utility model relates to survey instrument.

Common vernier height gauge commonly used by base, stands upright on the main scale on the base, be arranged on the slip vernier on the main scale, be connected single chi pin on the vernier (measurement faces and calls positive chi pin in the following text, and measuring faces up claims anti-chi pin) by clamp, and the micromatic setting that is connected on the slip vernier is formed.This vernier height gauge can be used for apparent size line, the measurement of solid usually, still, in practical operation, has the following disadvantages: 1, need two height gauges at least.Because one only has positive chi pin or a kind of state of anti-chi pin to height gauge, wherein positive chi pin can directly be read reading, and anti-chi pin can not be read reading, can only measure anti-chi pin with positive chi pin, just can draw reading.Operation is loaded down with trivial details like this.2,, measure and line for larger-size solid inconvenience because the positive chi pin of height gauge is shorter.3, especially energy measurement is dark not recessed in the inner structure size on solid surface.

The purpose of this utility model is the deficiency at above-mentioned common vernier height gauge, provide a kind of easy and simple to handle, reading is easy, the solid apparent size can be advantageously used in measuring, the multi-functional vernier height gauge of dark recessed inner structure size in the solid surface can be used to measure again.

The multi-functional vernier height gauge of the utility model comprises base and stands upright on graduated main scale on the base, it is characterized in that: be arranged on the abnormity slip vernier that has scale on the main scale, the one end can connect anti-chi pin, the other end by the long positive chi pin of clamp connection by clamp.And deflect away to one side and to avoid the main scale axis, make long positive chi pin free to advance or retreat.And, on long positive chi pin, be provided with by special-shaped two-dimentional slide block that all indicates scale and the special-shaped pit gauge that feeler lever constituted that in its groove, slides up and down.Key is: after long positive chi pin, anti-chi pin, the combination of special-shaped pit gauge, no matter how special-shaped slip vernier is on the same horizontal line in the measurement face beginning of slip three on the main scale, special-shaped slip vernier is connected with fine-tuning nut by a fine setting screw rod transfers piece.The fine setting piece, special-shaped two-dimentional sliding shoe, all trip bolt in the clamping.A kind of form of the base in the utility model is a medium base, and another kind of form is the base that offers a groove with respect to long positive chi needle axis.But best form is asymmetric base.

The multi-functional vernier height gauge structure of the utility model is simple and direct, reasonable in design, applied range, and one can replace two common height gauges to multi-functional vernier height gauge.Also can pull down special-shaped pit gauge and do common pit gauge use separately.Especially energy measurement is dark recessed in the inner structure size and the big-and-middle-sized solid apparent size on solid surface.Flexible and changeable, improved the utilization rate of measurer greatly, improved work efficiency and work quality, alleviated labour intensity.It is a kind of novel measurer of simple and direct practicality.

The concrete structure of the multi-functional vernier height gauge of the utility model and using method are provided in detail by the following drawings and embodiment.

Fig. 1, be the subjectivity figure of multi-functional vernier height gauge.

Fig. 2, be the vertical view of multi-functional vernier height gauge.

Embodiment: can know the concrete structure of seeing this multi-functional vernier height gauge from Fig. 1 and Fig. 2, each measurer title is among the figure: base (1), main scale (2), special-shaped slip vernier (3), fine-tuning nut (4), fine setting screw rod (6), fine setting piece (5), clamping screw (7), (8), (9), (13), clamp (10), (12), anti-chi pin (11), long positive chi pin (14), special-shaped two-dimentional slide block (15), clamping screw (16), feeler lever (17), clamping screw (18).Base (1) and main scale (2) and the abnormity slip vernier (3) that indicates straight vernier (19) are connected with anti-chi pin (11) by clamp (10), constitute anti-chi pin height gauge; Base (1), main scale (2) and the abnormity slip vernier (3) that indicates straight vernier (19) constitute by clamp (12) and long positive chi pin (14) grows positive chi pin height gauge; The length of the long positive chi pin of clamping screw (13) may command; Constitute the depth of special-shaped pit gauge, clamping screw (16) may command feeler lever by special-shaped two-dimentional slide block (15) that indicates small straight vernier and the feeler lever (17) that indicates scale.Clamping screw (18) can be fixed the position of special-shaped pit gauge on long positive chi pin.

The using method of this multi-functional vernier height gauge is given an example:

One: replace two height gauges to carry out the line of solid apparent size and measure.

Solid is after centering leveling on the platform, its upper dimension is measured with long positive chi pin (14), directly draw reading from main scale and vernier, after lower dimension is measured with anti-chi pin (11), because of positive and negative chi pin measurement face is on the same surface level, so also can directly draw reading from main scale and vernier, then before reading and back reading poor, be the poor of bottom profiled on the solid.

Two, the measurement solid is dark recessed in the inner structure size on surface.

By the small straight vernier (20) on the two-dimentional slide block of abnormity (15), after feeler lever (17) high scale is decided to be a certain numerical value, fastening with clamping screw (16), press special-shaped slip vernier (3) then, make feeler lever (17) go deep into solid inside by geodesic structure from solid top, draw reading by the straight vernier (19) on scale on the main scale (2) and the special-shaped slip vernier (3), deduct previous numerical value with this reading then, be solid inside by geodesic structure place size.

Three, use as common pit gauge.

1, will and indicate the feeler lever (17) of scale and special-shaped pit gauge that clamping screw (16) is formed takes off from long positive chi pin by the special-shaped two-dimentional slide block (15) that indicates small straight vernier (20), and can make common pit gauge separately and use.
