Abstract

The utility model discloses a meter used device capable of adjusting top and bottom limitation indication, which changes the top and bottom limitation indication manner of the traditional meter, and has the function of adjusting the indication position. The device comprises two layers of meter cases and two pointers, wherein the two layers of the meter cases are buckled so as to form a hollow box body; the two pointers are installed in the box body and are movably connected; the pointers and the meter cases are movably connected; two pointer shafts are combined to form a coaxial revolving body in an inner-outer nesting manner; and adjusting ports are arranged on both the two pointer shafts, so that tools such as screwdrivers are used for independently adjusting the positions of the first and the second pointers through the adjusting ports, and the top and bottom limitation indication in different positions are formed.

Description

Instrument scalable bound indicating device

Technical field

The utility model relates to a kind of instrument with scalable bound indicating device, is equipped with in the hollow box that double-deck watchcase, double-deck watchcase form two pointers are installed, and can do the location indication to the bound of instrument, belongs to measure test with instrument accessory field.

Background technology

Thermometric instrument, manometer, degree of depth instrument etc. are measured test and are used instrument, except having indicative function, also have warning function concurrently, when test data reaches upper limit or lower limit, remind the observation personnel to take as early as possible to remedy or the adjustment measure.At present, the upper limit that traditional measurement instrument has or the indication of lower limit generally adopt on index dial mark caution color to represent that the defective of making like this is the indicating range that can not change the upper limit or lower limit, sometimes have to adopt line, paste methods such as warning bar, operate very inconvenient.

The utility model content

The purpose of this utility model is the defective that exists at background technology, design provides a kind of instrument scalable bound indicating device, this device is made of double-deck watchcase and two pointer, double-deck watchcase fastens the box body that forms hollow, two pointers are installed in box body inside, be flexible connection between two pointers, be flexible connection between pointer and the watchcase, two needle pivots are combined into coaxial rotary body by inside and outside nested mode, on two needle pivots, be provided with and adjust mouth, can use instrument such as screwdriver by adjusting mouthful to first, second pointer position is adjusted separately, forms the bound indication of diverse location.

In order to achieve the above object, the utility model is realized by following technological means:

Instrument scalable bound indicating device, constitute by double-deck watchcase and two pointer, be flexible connection between two pointers, be flexible connection between pointer and the watchcase, two needle pivots are combined into coaxial rotary body by inside and outside nested mode, its composition comprises: go up watchcase, following watchcase, second pointer, first pointer, first needle pivot, second needle pivot, O type rubber ring, it is characterized in that: go up the box body that watchcase and following watchcase fasten formation hollow, be provided with through hole at the middle part of last watchcase and following watchcase; Fixedly connected between first pointer and first needle pivot, the upper end cylindrical of first needle pivot is provided with annular slot, is provided with O type rubber ring in annular slot; Fixedly connected between second pointer and second needle pivot, the lower end cylindrical of second needle pivot is provided with annular slot, is provided with O type rubber ring in annular slot; Middle part at first needle pivot is provided with through hole, be provided with horizontal adjustment mouth in the upper end of first needle pivot, be provided with horizontal adjustment mouthful in the upper end of second needle pivot, the upper end of second needle pivot can be interted in the through hole of first needle pivot into, forms the coaxial rotary body of nested combination;

Described O type rubber ring increases damping between needle pivot and watchcase through hole, pointer is temporarily fixed, and plays sealing function;

Described adjustment mouthful can use instrument such as screwdriver mouthful first, second pointer position to be adjusted separately by adjusting, and forms the bound indication of diverse location.

Last watchcase and following watchcase fasten the hollow box that forms, and are installed in the top of meter dial, replace the watchcase of conventional instrument.Last watchcase and following watchcase can be selected transparent materials such as glass, PVC for use.

The utility model mainly has following good effect and technical characterictic:

The instrument that the utility model provides scalable bound indicating device, rational in infrastructure, reliable in function, simple to operate, be mainly used in the bound indication of Displaying Meters such as existing pressure and temp, replace modes of operation such as ancient setting-out, joint strip, solve original setting-out joint strip and come off because of on-the-spot cargo sweat etc., with uncontrollable drawback, this device can not shake because of the scene, humidity, corrosion etc. are former thereby cause the skew of indication.Be widely used in a plurality of industry fields, be applicable to the bound indication of various instrument.
