Abstract

The utility model discloses a balance waterproof mechanism, which comprises a scale pan and a scale body cover, wherein the edge of the scale pan is provided with downward scale pan convex ribs, the edge of the upper end of the scale body cover is provided with upward scale body cover convex ribs, and the scale pan convex ribs and the scale body cover convex ribs are arranged in a staggered way. The mechanism can effectively prevent water and other liquid from entering an inner cavity of a balance, has the advantages of compact structure and low cost, and can be widely used in various balances.

Description

A kind of balance proof mechanism of water

Technical field

The utility model relates to the instrument and meter structure, and more particularly, it relates to a kind of waterproof construction design of balance.

Background technology

In electronic balance, there is certain space between the scale pan and the scale body lid, when use is especially used in the laboratory; regular meeting contacts with liquid, thus the time have liquid to be splashed into or spray into scale body inside, the corrosion instrument; influence the weighing accuracy, even cause the internal wiring short circuit of scale body and frequent the repairing.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of proof mechanism of water of balance is provided, and makes balance suit to use having under water and other liquid environments.

The purpose of this utility model is achieved through the following technical solutions, according to the balance proof mechanism of water that the utility model proposes, comprise the scale pan and scale body lid, scale pan edge is provided with downward scale pan fin, the scale body covers end margin and is provided with the scale body lid fin that makes progress, and scale pan fin and scale body lid fin are crisscross arranged.Scale pan fin does not contact with scale body lid, and scale body lid fin does not contact with the scale pan yet.Scale pan fin and scale body lid fin be arranged in parallel, do not contact mutually, and scale pan fin is arranged on the corresponding scale body lid fin outside, and the upper end of scale body lid fin is higher slightly than the lower end of scale pan fin.

Described scale pan fin is made as ring-type, and corresponding scale body lid fin also is a ring-type.This ring-type generally can be provided with according to scale pan shape, can be circular or other geometric configuratioies.

As optimal way, two or more the scale pan fin of be arrangeding in parallel, corresponding scale body lid fin also be arranged two or more in parallel.Better, scale pan fin is made as three, and corresponding scale body lid fin is made as three, forms inboard groove and outside groove between the adjacent scale body lid fin, is used to compile the liquid that is splashed into.For getting rid of the liquid that is splashed into better, on scale body lid fin, be provided with one or more breach, the breach on the adjacent medial and lateral scale body lid fin should not be oppositely arranged, in order to avoid liquid is splashed into.The comparable outside, inboard groove bottom groove is high slightly, is beneficial to liquid and flows out.

By structural arrangements mode of the present utility model,, can prevent effectively that sealing and other liquid enter the balance inner chamber, in order to the normal use of balance owing to be provided with proof mechanism of water in the balance.The utility model compact conformation, easy to use, low cost of manufacture is with a wide range of applications.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Accompanying drawing 1, Fig. 2, Fig. 3 and Figure 4 shows that preferred embodiment of the present utility model, the balance proof mechanism of water of this embodiment comprises the scale pan 1 and scale body lid 2, scale pan edge 10 is provided with four downward scale pan fins 101 abreast, the scale body covers end margin 20 and is provided with three scale body lid fins 201 that make progress abreast, scale pan fin 101 does not contact with scale body lid 2, and scale body lid fin 201 does not contact with the scale pan 1 yet; Scale pan fin 101 and scale body lid fin 201 are annular, the rectangle that is fillet, scale pan fin 101 is except that the outermost fin, its excess-three bar and scale body lid fin 201 are crisscross arranged abreast, do not contact mutually, scale pan fin 201 is arranged on corresponding scale body lid fin 201 outsides, and the upper end of scale body lid fin 201 is higher slightly than the lower end of scale pan fin 101.Form inboard groove 202 and outside groove 203 between the adjacent scale body lid fin 201, on scale body lid fin 201, evenly be provided with a plurality of breach 204, be used for discharge opeing, the setting of staggering of 204 of breach on the adjacent medial and lateral scale bodies lid fin, inboard groove 202 bottoms are higher slightly than outside groove 203, are beneficial to liquid and flow out.Do not establish breach on the most inboard scale body lid fin, in order to avoid liquid flows into the balance inner chamber.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs within the scope of technical solutions of the utility model any simple modification, equivalent variations or modification that above embodiment did.
