DE6902667U - TRANSLATION OR COUNTERS, IN PARTICULAR FOR WATER METERS - Google Patents

Description

The "price increase" concerns a translation oäer Gäiil-werl :, especially for water meters, with an upper and a lower plastic bearing plate, -which above decency molded onto one of the "two bearing plates The pillars are connected to each other.

With "known translation and counters" these These are the spacer columns molded onto a bearing plate by means of metal countersunk screws, which mostly serve to center the work cages at the same time, with the other! These The type of mounting is both "for pointer display units" and " also "in the various embodiments Oval display works usual-

The innovation is based on the task of creating a translation or counter especially for water meters to create in which screw connections are largely avoided.

This should not only enable the production of a completely plastic plant, but also a more precise centering of the plates used to support the ■ transmission and indexing wheels are made possible, which at the same time significantly simplifies production.

This object is achieved according to the invention in that the spacer columns molded onto a bearing plate with the other bearing plate by releasable snap. Conclusions are connected.

These snap closures can advantageously Be designed like a push button.

In an advantageous embodiment of the! Inflation is also the known running plate, which determines the axial running play of the ¥ erksräder, by at least a releasable snapper he was set on one of the bearing plates. In this way it is separate from this one Bearing plate set so that they can be solved in a very simple manner when cleaning or repairing can. Usually the snap is like that designed so that the running plate can be reattached in a different position. Suitable for this For example, a central snap lock or several symmetrically arranged, identical snap locks, an offset of the running plate with respect to the bearing plates

enable. This implementation option is desirable since the shaft journals of the "transmission gears can dig more or less deeply into the running plate after a long period of running.

In a further advantageous embodiment of the innovation, the dial is also preferred also made of plastic "consists of at least one releasable snap lock on one of the bearing plates set. In this embodiment, all parts of the translation and metering information can be used Plastic made so that it can be assembled and installed in the simplest possible manner and with simple tools

can be dismantled if necessary.

Preferably, the snap locks are used Parts directly to the plastic spacer columns, Bearing plates, running plates or dials are molded on and are thus in manufactured in one operation. This makes not only the manufacture but also the assembly extraordinary simplified, since no special ones from the plates separate fasteners are more required.

The shaft 6 of a counter drive wheel is mounted in the upper bearing plate 1 and the “lower! one-piece injection-molded, snap-fastener-shaped snap fastener part 10 is provided, which is snapped into a correspondingly shaped recess 11 of the lower bearing plate which forms the other part of the snap fastener ". By releasing the snap lock 10, 11, the running plate 9 can be removed, cleaned and overhauled in a simple manner and can then be snapped in again in a rotated position, thereby extending its service life.

That in the pig. 4-7 shown counting or display mechanism is essentially constructed in the same way as the transmission mechanism shown in FIGS. 1-3. Same or corresponding parts are therefore provided with the same reference numerals. It should be noted that with the The embodiment shown in FIGS. 1-3 shows the snap-button-shaped part 4 or 10 of the snap fasteners is molded in one piece on the lower bearing plate 2 or on the running plate 10, while in contrast to this, the push-button-shaped part 4 in the embodiment shown in FIGS. 4-7 is molded onto the spacer columns 3 in one piece. In the same way, of course, the push-button-shaped snap-lock part 10 could also be used instead of the running plate 9 can be injection-molded in one piece on the lower bearing plate 2.

The dial 13 of this embodiment is connected to the upper bearing plate 12, which has recesses 15 representing the other part of the snap locks, by means of two integrally molded, push-button-shaped locking parts 14.
