Abstract

The utility model provides a portable steelyard, which is characterized in that a counterweight forms a rod shape and is assembled in a tubular steelyard beam in a sliding mode; the weighing balance is realized by utilizing the rod-shaped counterweight to slide in the tubular steelyard beam. The weight of an object is read at the corresponding scale of the rod-shaped counterweight extending from the port of the tubular steelyard beam. The portable steelyard has the advantages of compact structure, convenient use and portability.

Description

Portable steelyard

The utility model relates to a kind of portable lever scale, the telescopic portable lever scale of particularly a kind of arm beam of steelyard.

General portable lever is because the sliding weight of steelyard and the arm beam of steelyard respectively are one in the city now, and the arm beam of steelyard is longer again, carries and use inconvenience.

The purpose that this practicality is new: provide a kind of portable lever scale easy to use and carry.

The utility model is achieved in that to making and carries with easy to use, and the arm beam of steelyard is made two sections by one to one length branch, makes tubulose for one section that has the handle steelyard hook, and another section made solid rod-like with the bigger metal of proportion and replaced sliding weight of steelyard, is called shaft-like sliding weight of steelyard.And shaft-like sliding weight of steelyard is fitted in the tubulose arm beam of steelyard with the slip form.Utilize the slippage in the tubulose arm beam of steelyard of shaft-like sliding weight of steelyard, make its distance that changes the portable fulcrum of distance of centre of gravity of shaft-like sliding weight of steelyard, be implemented in when weighing portable fulcrum two end moments and equate, realize weighing balance.

The utility model makes shaft-like sliding weight of steelyard promptly replace the arm beam of steelyard to replace sliding weight of steelyard again because of adopting the telescopic arm beam of steelyard, has not only shortened the length of carrying of the arm beam of steelyard, makes volume little, and is easy to use and carry.

The concrete structure of invention is drawn by following embodiment and accompanying drawing.

Accompanying drawing is the principal section figure and the handle sectional view of the portable portable lever scale that provides according to the utility model.

Describe the concrete structure and the working condition of portable lever scale in detail below in conjunction with accompanying drawing.

In the accompanying drawings, the shaft-like sliding weight of steelyard (1) that indicates the weighing scale is fitted in the tubulose arm beam of steelyard (2) with the slip form, for preventing that shaft-like sliding weight of steelyard (1) from separating with the tubulose arm beam of steelyard (2), on shaft-like sliding weight of steelyard (1), have two symmetrical slideways, and install with last two spacer pins of the tubulose arm beam of steelyard (2) (3) are corresponding one by one.The semi-circular right angle hook of handle (4) and steelyard hook (5) inserts in the corresponding aperture of the tubulose arm beam of steelyard (2), and free to rotate.Handle (4) has a bit of distance with steelyard hook (5).When shaft-like sliding weight of steelyard (1) when steelyard hook (5) direction of the tubulose arm beam of steelyard (2) is pulled out apart from the tubulose arm beam of steelyard (2) port certain-length, make scale arm beam of steelyard when not weighing be in equilibrium state.At this moment shaft-like sliding weight of steelyard (1) is the zero mark of heavily marking with the corresponding scale of the tubulose arm beam of steelyard (2) port.When weighing shaft-like sliding weight of steelyard (1) is pushed in the tubulose arm beam of steelyard (2).Or pull out from an other end of the tubulose arm beam of steelyard (2) and to realize weighing balance.And it is heavy to read thing with the shaft-like sliding weight of steelyard (1) and the corresponding scale of the tubulose arm beam of steelyard (2) port.When shaft-like sliding weight of steelyard (1) all advances the tubulose arm beam of steelyard (2), shaft-like sliding weight of steelyard (1) is the same scale of weighing with the corresponding scale of the tubulose arm beam of steelyard (2) two-port, and the tubulose arm beam of steelyard (2) can be that a joint or more piece are assembled together to be slidingly matched to satisfy the range needs of weighing more greatly.

Claims

1, a kind of portable portable lever scale of being made up of the tubulose arm beam of steelyard (2), shaft-like sliding weight of steelyard (1), handle (4), steelyard hook (5), spacer pin (3) is characterized in that shaft-like sliding weight of steelyard (1) is fitted in the tubulose arm beam of steelyard (2) with the slip form.

2, by the described device of claim 1, it is characterized in that shaft-like sliding weight of steelyard (1) is the solid metal right cylinder.

3, by the described device of claim 2, it is characterized in that the surface of shaft-like sliding weight of steelyard (1) indicates some weighing scales.
