Description

Portable lever scale

Technical Field

The utility model relates to a portable type steelyard.

Background

A steelyard, also called a steelyard, is a kind of steelyard, which is a simple weighing apparatus for weighing mass by using lever principle, and generally consists of a wooden steelyard beam with a star, a metal weight, a handle and the like. It has the advantages of simple structure, convenient use and the like, and is widely used by many people.

But the scale beam is longer and the scale beam and the weight are used separately, so the scale is not easy to carry.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model aims to provide a portable lever scale.

In order to achieve the purpose, the portable lever scale comprises a scale beam and a weight, wherein the front end of the scale beam is pivoted with a handle and a scale hook at intervals; the weight is in a hollow tubular shape, and the upper part or the bottom of the weight is connected with a cover through threads; the scale beam is a telescopic scale beam, and a weight can be placed into the scale beam as a hollow part after the scale beam is contracted.

Furthermore, the scale hook is a folding metal hook and comprises two L-shaped metal hooks hinged on two sides of the front end of the scale beam and arranged in parallel and a connecting section for connecting the two L-shaped metal hooks;

wherein each L-shaped metal hook comprises: the long vertical section is hinged at the front end of the scale beam, the bottom of the long vertical section is connected with the horizontal section forwards, and the front end of the horizontal section is connected with the short vertical section;

the front end of the short vertical section is connected with two L-shaped metal hooks into a whole by a connecting section;

wherein, the length of the horizontal section is equivalent to the length from the lower surface of the scale beam to the articulated shaft of the scale hook.

Furthermore, the handle is a folding metal handle.

The utility model is hollow, the scale beam is a telescopic scale beam, and the scale beam can be placed into the hollow part after being contracted; furthermore, a foldable scale hook is provided, so that the whole scale is small in length and diameter and is suitable for carrying. Can be used for weighing objects with relatively light weight.

Detailed Description

The invention will be further described with reference to the accompanying drawings and examples

As shown in fig. 1-5, the portable steelyard of the present invention comprises a steelyard beam 1 and a steelyard weight 2, wherein a handle 3 and a steelyard hook 4 are pivoted at the front end of the steelyard beam at intervals; the weight is in a hollow tubular shape, and the upper part or the bottom of the weight is connected with a cover 21 through threads; the scale beam 1 is a telescopic scale beam, and a weight can be placed into the scale beam as a hollow part after the scale beam is contracted.

The scale hook is a folding metal hook and comprises two L-shaped metal hooks hinged on two sides of the front end of the scale beam and arranged in parallel and a connecting section for connecting the two L-shaped metal hooks;

wherein each L-shaped metal hook comprises: a long vertical section 41 hinged at the front end of the scale beam, wherein the upper end of the long vertical section 41 is provided with a hinged part, the bottom of the long vertical section is forwardly connected with a horizontal section 42, and the front end of the horizontal section is connected with a short vertical section 43; the front end of the short vertical section is connected with two L-shaped metal hooks into a whole by a connecting section 44;

wherein the length of the horizontal section 42 is equivalent to the length from the lower surface of the scale beam to the articulated shaft of the scale hook.

Similarly, the handle is a folding metal handle. As shown in fig. 1, the scale hook 4 is located at the front end of the scale beam, which is folded back; the handle 3 is positioned behind the scale hook and is folded forwards; therefore, a large amount of space can be saved, the balance hook can be made of metal, the service life is long, and the balance hook is not easy to damage.

Fig. 3 is a schematic structural view of a folded scale beam, a scale hook and a handle, which are placed in a hollow part of a weight.
