Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a starter structure in an indicator attached to a liquefied gas cylinder, for example.

[Background of the invention]

For example, as a main structure of an indicator for detecting the amount of liquefied gas, there is a structure as shown in FIG.
Reference numeral 1 denotes a base plate. A support shaft 2 is attached to the base plate 1, and a pointer shaft 4 integrally provided with a rotor 3 is pivotally supported on the support shaft 2. Further, a movable contact plate 5 integrated with the pointer shaft 4 and the rotor 3 is provided, and a movable contact 6 mounted on the free end side of the movable contact plate 5.
Is fixed inside the transparent case 7 and slidably contacts a resistance layer 9 formed on the lower surface (back surface) of the resistance plate 8 having a through hole 8'for inserting a pointer in the central portion. , Is urged by the elasticity of the contact plate 5. A pointer 10 is attached to the tip of the pointer shaft 4, and the pointer 10 is located on the surface of the resistor 9.

In order to assemble the indicator-equipped transmitter having the above structure, the movable contact plate 5 and the pointer 10 fixed to the pointer shaft 4 are assembled.
Case 7 in which resistance plate 8 is assembled
Before the installation, the movable contact plate 5 attached to the pointer shaft 4 is opened by its restoring force, and as shown in FIGS. 5 and 6, the tip of the movable contact plate 5 is assembled. Since the movable contact 6 attached to the pointer 10 is in contact with the pointer 10, the pointer 10 is positioned on the front side of the resistance plate 8 and the movable contact 6 is positioned on the back side of the resistance plate 8 ( It is difficult to guide the resistance plate 8 between the pointer 10 and the contact 6 even if it is desired to assemble it (as indicated by the chain line in FIG. 6), and the movable contact plate 5 and the pointer 10 are assembled. There was a problem that the workability of assembling the inside of the case was poor.

[Purpose of device]

The present invention has been made to solve such a problem, and when the movable contact plate 5 and the pointer 10 are assembled in the case 7, the movable contact 6 provided on the movable contact plate 5 is removed from the pointer 10. Providing a talkable protrusion so that it is easy to position the resistance plate 8 between the protrusions, that is, between the movable contact 6 and the pointer, for ease and quick assembly. The purpose is to provide a transmitter with an indicator.

[Example of device]

Hereinafter, the present invention will be described in detail based on the embodiment shown in FIGS. 1 to 3. The same portions as the structure in the present embodiment and the structure shown in the conventional example are cited in the conventional example. The reference numerals are given and the structural description thereof is omitted.

That is, the feature of this embodiment is that the protrusion 12 extending in the thickness direction of the resistance plate 8 is integrated with the case 7 by being positioned inside the insertion notch 11 of the pointer 10 provided on the resistance plate 8. Further, the protruding end of the protrusion 12 is set to slightly protrude from the back surface of the counter plate 8 (see FIG. 1).

In this way, when assembling the transmitter, use the pointer 8
Since the protrusion 12 protruding from the upper surface to the lower surface of the resistance plate 8 is provided in the notch 11 for passing the resistance plate 8 upward,
When passing the inside of the notch 11 from the lower side to the upper side, the pointer 10 passes through the inside of the notch 11, but the notch 11
Since the tip of the movable contact plate 5 having a width substantially equal to the width of the pointer is locked by the protrusion 12 and is prevented from passing through the notch 11, the pointer 10 as shown in FIG. Only the power is transmitted to the front side of the resistance plate 8, and the contact plate 5 remains positioned on the back side of the resistance plate 8 so that the movable contact 6 of the contact plate 5 is moved.
When the contact plate 5 and the pointer 10 are rotated in the circumferential direction in this state, the pointer 10 is positioned on the front side of the resistance plate 8 as shown by the chain line in FIG. The movable contact 6 can be pressed against the back side of the resistance plate 8, that is, the resistance 9.

Therefore, according to this embodiment, the protrusion 12 is provided, and the movable contact can be widened by the protrusion 12 to widen between the contact and the pointer. Therefore, the movable contact plate 5 and the pointer 10 can be expanded. When assembling the assembly with the resistance plate 8 in the case 7 in which the resistance plate 8 is assembled, the pointer 10 is on the front side of the resistance plate 8 and the movable contact 6 provided on the movable contact 5 is the resistance plate. Since the resistance plate 8 can be located on the resistance layer 9 provided on the back side of the plate 8, and then the resistance plate 8 can be inserted between the movable contact 6 and the pointer 10, the assembly thereof is extremely easy, and the work is completed. Has the effect of significantly improving the property.

[Outline of device]

As described above, according to the present invention, the pointer 10 is fixed to one end of the pointer shaft 4, and the elastic tongue 5 to which the movable contact 6 is fixed is fixed to the pointer shaft 4 substantially in parallel with the pointer 4, 6
And a pointer 10 are provided with a through hole 8'through which the pointer shaft 4 penetrates, and a notch 11 at a peripheral edge of the through hole 8 ', and a display index is provided on the front surface and slidably contacts the movable contact 6 on the back surface. In a transmitter with an indicator, in which an annular resistance plate 8 provided with a sliding resistance layer 9 is disposed and which outputs a value indicated by a pointer 4 as a resistance value on the resistance plate, the resistance plate is passed through the notch 11. 8 extends from the front surface side to the back surface side of the movable contact 6
Is a transmitter with an indicator for restricting the entry into the notch 11.

[Effect of device]

Therefore, according to this transmitter with an indicator, the movable contact is expanded by the action of the projection 12, and the distance between this contact and the pointer is increased.
Since the movable contact plate 5 and the pointer 10 are assembled in the case 7 in which the resistance plate 8 is assembled, the pointer 10 is on the front side of the resistance plate 8, In addition, the movable contact 6 provided on the movable contact plate 5
Can be positioned on the resistance layer 9 provided on the back side of the resistance plate 8, and then the resistance plate 8 can be inserted between the movable contact 6 and the pointer 10, so that the assembling thereof is extremely easy. As a result, workability is significantly improved.
