Abstract

The utility model relates to a warning mark structure of a micro differential pressure meter, comprising a meter base, a transparent shell and at least one mark, wherein the inner part of the meter base comprises a pointer which does arc-shaped motion from the axle center and is matched with a scale plate for displaying values; the transparent shell is superimposed outside the meter base; at least one concave part is arranged on the transparent shell in the motion range of the pointer; and the mark is provided with a clamping part which is embedded at the concave part. Therefore, a user can set the mark at the concave part of the corresponding value of the scale plate according to needs so as to be convenient for interpreting whether the pointer and the value are in reasonable interval or exceed the standard value and further be beneficial to carrying out processing instantaneously.

Description

The alert flag structure of little differential pressure gauge

Technical field

The alert flag structure of the little differential pressure gauge of the utility model, the mark additional structure is used in the safety indication that relates to a kind of pointer table tool, particularly mark is additional in the recess default on the transparent shell.

Background technology

Existing gauging table, for example micro-differential pressure gauge or tensimeter have pointer in its table, and pointer can cooperate the digital calibration plate in the table with the pressure status turn, and personnel can be provided visual reading numerical values.Gauging table all is set with security value (s) on the practice, whether be in the safe range for making things convenient for personnel to understand pointer, all should add on gauging table and hang with safety label, for example tw Taiwan invention bulletin I232927 number " the gauging table pointerforsafety structure of tool fixed function " is an example.

The creator finds, comprise the aforementioned case of quoting as proof in interior existing label fixed, all be in the gauging table outer edge, if when chimeric mode need be adopted in the place of these gauging table settings, (for example dig out hole on the flat board at equipment and bury gauging table underground), existing structure because of the gauging table periphery fully and flat board closely cooperate, can't additional marking; For solving this problem, the creator researches and develops this case, and the phase can provide the structure in a kind of not limited use location and place, to satisfy the industry demand.

Summary of the invention

The utility model provides a kind of alert flag structure of little differential pressure gauge, its fundamental purpose is: the additional structure-improved that a kind of security warning mark is provided, its caution is to be arranged in the scope of transparent shell with mark, that is the adjustment mark does not have the situation that exceeds the gauging table circumference, thus, even if gauging table is adopted and chimericly is provided with by the dress mode, mark still can be easy in additional and be convenient to use.

For reaching above-mentioned purpose, the utility model provides a kind of alert flag structure of little differential pressure gauge, and it comprises:

One gauge stand, inside includes pointer, and described pointer carries out arcuate movement by the axle center, cooperates a scaleplate to be used to show numerical value;

One transparent shell is overlapping in outside the described gauge stand, is positioned at described hand motion scope on the described transparent shell, is provided with at least one recess;

At least one mark, described mark has the card division, and described card division embedding group is in described recess.

In the preferred implementation, described recess is to be arranged with on described transparent shell, but does not pass through described transparent shell.

In the preferred implementation, be the packing relation between described recess and described card division.

In the preferred implementation, the shape of described mark is the tip with directive property.

In the preferred implementation, described mark has color, and described color comprises redness.

The utility model since mark be arranged in the circumference range of transparent shell, therefore, quite desirable even if gauging table is adopted the mode that is embedded in the plate body and is embedded also and do not hinder; Moreover, because of mark is to be stacked at pointers outside, so interpretation is also quite clear.

Description of reference numerals: 1-gauge stand; The 20-axle center; The 21-pointer; The 22-scaleplate; The 3-transparent shell; The 31-recess; The 4-mark; The 41-card division.

Embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

See also Fig. 1 and shown in Figure 2, the alert flag structure of the little differential pressure gauge of this case comprises:

One gauge stand 1 can become pointer gauging table behind inner other part of combination, comprises but is not defined as tensimeter or micro-differential pressure gauge; Inside is provided with a pointer 21, and it can carry out arcuate movement according to internal pressure by axle center 20, cooperates scaleplate 22 to show numerical value;

One transparent shell 3, be transparence, be overlapping in outside the gauge stand 1, on the described transparent shell 3, be preset with at least one recess 31, described recess 31 can correspond to the moving section scope of pointer 21 or scaleplate 22, and described recess 31 is to be arranged with suitable distance on transparent shell 3, but can not pass through transparent shell 3; And other includes mark 4, and described mark 4 has card division 41, utilizes card division 41 is embedded at recess 31, can reach mark 4 is bonded to purpose on the transparent shell 3.

Aforementioned recess 31 and card division 41 slightly are the packing relation between the two.

Aforementioned mark 4 is good with the tip with directive property in the shape, and it can have color, and is for example red, to highlight warning function.

As shown in Figure 3, when this case is implemented, make mark 4 be sticked on the recess 31 at required caution numerical value place; utilize two marks 4 just can indicate the security interval and caution critical value of numerical value; if pointer 21 surmounts arbitrary mark 4, the visual discovery quite easily and interpretation can be carried out crisis at once and be handled.

See also Fig. 4 again, because transparent shell 3 is provided with a plurality of recesses 31, the user can change caution numerical value in order to according to specific time and site, to satisfy the needs of extensive or different occasions according to the position that needed any shift sign 4 to add at that time.

The structure of this case, because it is mark 4 is arranged in the circumference range of transparent shell 3,, quite desirable even if therefore gauging table is adopted the mode that is embedded in the plate body and is embedded also and do not hinder; Moreover, because of mark 4 is to be stacked at pointer 21 outsides, so interpretation is also quite clear.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
