Description

Electric contact type pressure gauge indicator device

The utility model system is relevant with the pressure gauge pointer structure, more detailed it, refer to a kind of easy to operate and electric contact type pressure gauge indicator device that accuracy is high especially, belong to the instrument product of gaging pressure.

As everyone knows, at present general pressure gauge pointer structure, as Fig. 1, shown in Figure 1B, it mainly is to contain a pressure setting apparatus (1), and this pressure setting apparatus (1) is a pipeline (2) air pressure is pressed in the pressure setting apparatus (1), control through internal circuit, the predetermined pressure number how much, drive pointer (4) by the spring (3) of this pressure setting apparatus (1) inside again and on panel (5) scale, show, but this pressure setting apparatus (1) must be used the competence exertion function with a pressure gauge (6) again.In addition, the structure of planting shown in Figure 1A, Fig. 1 C is arranged, it also is to contain a pressure switch device (7), and adds a pressure gauge (6) in addition again, therefore following some drawback occurs by top described structure regular meeting:

1. pressure gauge pointer and pressure setting apparatus pointer are independent separately, increase manufacturing cost.

2. can't single job finish when using, need separate operation, waste man-hour.

3. observe pressure and change situation, can't come into plain view, need check the situation of both sides pressure gauge and pressure setting apparatus.

4. tolerance big (having 15% at least) is adjusted and pointer is difficult, and easy temperature influence.

In view of this, the fundamental purpose of the utility model is: design the electric contact type pressure gauge indicator device that a kind of cost is low, simple to operate, observation is convenient, error is little.

A kind of electric contact type pressure gauge of the utility model indicator device is to include:

One electric contact type pressure gauge gauge outfit, it is the tensimeter of electric contact type control;

One number pressure pointer joins with gauge outfit, establishes a straight-bar above the syringe needle;

One holder is to be long oval lamellar body, establishes two bodies of rod above the lamellar body, and a stator is established in its both sides, and establishes screw and lock fixing for screw;

One connecting rod reed, lamellar body front end are established a reed trace, offer two circular holes on the body, and its side extends an electric wire contact;

One magnetite sheet, lamellar body front end are established a magnetite bar, and a magnetite is established in body of rod below, and a side is extended a flange hole, and the magnetite forward end is established a cross bar, for the reed trace push and block of connecting rod reed, also offers two circular holes in addition on body, and an electric wire contact;

One pressure is set pointer, establishes four circular holes on the body, and front end is established a bending needle body, and needle body is respectively established a straight-bar up and down;

One last slice, establish two circular holes on its lamellar body, join for screw and pressure setting pointer;

A plurality of partitions are established two circular holes on its lamellar body, and its lamellar body has certain thickness, have certain distance for after being separated by;

One lid is established a circular hole on its lid, on the circular hole for locking one remote-control lever that stretches through, and above packing ring, nut and the rotor wheel established;

The mat combinations thereof, by the bipole body of this holder with the combination that stretches through of each element, fix by screw closure again, and by this electric contact type pressure gauge built-in function control, make pointer on graduation apparatus, rotate, and keep out mutually by the straight-bar that its device is gone up and to move, make number pressure pointer and pressure setting pointer cooperatively interact, by display digit on the meter dial, and the size of the number pressure that is effectively controlled.

The utility model has the advantages that:

1. operation easily is not subjected to influence of temperature change.

2. a table can be operated simultaneously, and tolerance is little, accuracy height (in the error 1.5%).

3. stable because of electric current and voltage, so the pointer running is safe and simple.
