Description

electronic hand scales

The alleged invention for an industrial design relates to a sound-technical technique and can be used for manual weighing of goods during trading operations; In this case, arithmetic operations with numbers can be performed. measured weight values. In addition, the proposed device can be used as a conventional glyc calculator,

. Famous household hand-held whole; for example, VBC-10, with a mechanical pointer and a hook for suspension of goods. Differing from oii and cheap, this type of balance does not provide readings after unloading and has disadvantages associated with the presence of a wide measuring device (subjective errors with different viewing angles, inconvenience of reading).

Known manual electronic scales / I /, containing a strain gauge module and an electronic circuit with a digital indicator and battery powered, made in a housing made of hard plastic and having a load receiving platform /.

In these scales, the function of the electronic circuit is limited by the conversion of the measured quantity and the formation of signals on the indicator. The scales of the boards only place the load on the platform.

Known electronic hand scales type steelyard / 2 /, held in the process by the handle of a rectangular shape, which is connected to a housing having a parallelepiped force. An optical digital indicator is located in the upper part of the front panel of the case; under us is a window into which an electric battery is inserted. Inside the casing, there are: two prkhlohHolny-plodn; 1 of the former, one of which is connected about the opera tional forces with a vertical rod. To this, the force-hooking hook exhaled from the bottom of the case has been erased.

Such a construction is preferable if the nature of the load allows it to be suspended directly on the hook, or placed in a container with a suspension device.

This device / 2 / is the closest to the alleged invention and comes from the prototype. Its disadvantage, as well as devices with a platform for the load / I /, remains limited functions.

Microcalculators are known, for example, domestic Electronics (Zh-51, Zh-52 and DO.). They sew indisputable advantages With compactness, accessibility), however, the field of their practical application is limited primarily due to the significantly larger possibilities that weakened personal computers. It seems advisable to find ways to expand the scope of application of Gcal-Calculagoro:

Щ) and the creation of a new device, the task of expanding the function of electronic hand-held scales is solved, namely, the creation of the possibility of using them as a microcalculator itself, as well as the creation of an opportunity to place a weighed body (material) both on a hook and on a load-bearing cup.

This is achieved by the fact that, as a calculator with a keyboard and an indicator, a microcalculator integrated in the housing is used. the interface card of this microcalculate is also tightened,

With load cell. The code / compactness necessary to use the proposed device as a microcalculator is provided by incorporating force measuring plates and a power transmitting rod into the handle. The handle is not located on top (as in the prototype device), but on the side with respect to the body.

The possibility of placing the load on the cup, along with the possibility of hanging it on the oil receiving hook, is provided by the fact that the load set includes a load receptacle, which, if not necessary, is connected to the silt with the operating rod on top, and a stand that is attached from below to the handle of the case, And the cup and The attachment can be easily removed if there is no need for 1-shh.

Comparative analysis with the prototype shows that the load meter in the inventive device is significantly different from the load meter of the prototype in principle and in geometry, and the calculator with the prototype indicator is indented with a calculator. All this allows us to conclude that the claimed device meets the criterion of novelty.

All the previously mentioned components of the proposed electronic 4X weighing plate and the force meter bar-h, a micro calculator, a housing with a handle, a removable lifting bowl are known per se. However, the combination of these components in the claimed design provides a combination of (electronic scales with universal placement of goods and a micro calculator. The relative position of the load cell elements - plates and the rod - and their placement in the handle of the housing are IMPORTANT to achieve the required compactness. Therefore, the claimed device meets the criterion of significant differences .

The invention is illustrated by drawings (figL-Z).

On Fig presents the main image of the design of the proposed device; figure 2,3 - respectively vice from above and left

(without kzhuha).

All parts and components of the scales are fixed inside the case, which in the considered version is prefabricated (but it can also be completely staged). The base of the case is two symmetric parallel steshes I (fIGl-3) and fixing them at a certain distance.

each from the arc-shaped struts 2,3 (Fig 2,3). To the rear posts - upper and lower - there are two flat springs attached to the console

4 (Fig. 2,3) of the load cell with a strain gauge glued on them

5 (figure 2); the springs are located horizontally and parallel to each other, and their ends are rigidly connected to the vertical force-transmitting rod 6 (Fig.Z) so that they form a parallelogram mechanism along with it. Bottom to the vertical rod 6 (Fig.Z) is attached a power-receiving hook 7 (Fig.1),

On the outside of the front wall there is a niche in size of a microcalculator; such a niche with a niche located on the outside of the rear wall. In the indicated recesses of the walls, a calculator 8 (Fig. 1, 2) and a conjugation board 9 are installed and not fixed. The space (cavity) between it serves to place the batteries 10 (Fig. 3).

In the walls of I, holes were made to communicate with the indicated cavity for making electrical connections between the ivmK calculator, the interface board, strain gages, and batteries (not shown).

In the remaining part of each wall there is a through window, sufficient in size for the fingers to pass into it. Thanks to such opposite windows, these parts of the walls are the basis of the handle II (Fig. 1).

Between the walls in the considered part of the body - the handle are the elements of the load meter: flat springs 4 (Fig.2,3) and the rod 6 (Fig.Z).

The kit of the proposed device also includes a load-tightening bowl 12 and a stand 13 (Fig. 3). On the outside of the bottom of the cup 12 И1У1 there is a protrusion with a threaded hole, due to which the cup can be screwed onto the force-transmitting rod 6 (fig.Z). considered weights. The stand 13 is provided with four symmetrically

- -Ztsd1

located 1 / sh. with pins that enter the ear from it up and provide a pairing with the housing. For this, corresponding holes were drilled in the walls of the housing I from the base side.

The device operates as follows.

When determining the weight of the load, it is either suspended on a power-receiving hook (in containers or directly), or located on a removable load-receiving cup on top, in the first case the scales are held by the handle, where a special power switch is sewn, in the second they are mounted on a removable stand. The power of the load cells and the entire electronic part of the device is turned on. Select the weighing result; it is displayed on the digital indicator of the calculator; with a given number autoglathically entered in the operand-free register of the calculator, calculations can be performed in accordance with the capabilities of the microcalculate ora.

When working with the device as with a conventional calculator, the power hook, stand and load cell are removed for convenience.

The above-described scales in a specific design have the following main characteristics:

- measuring range P 04.2 kgf;

- error no more than 0,

-Dimensions 140 x 130 x 40 mm.

IvmKp is integrated into the body of these weights. About 1ZH-51 and six 316 Uranium elements (or their analogues) are built.
