Abstract

The utility model belongs to a measuring device, in particular to a sliding type portable balance, which comprises a balance bar (1), a balancing counterweight (3), a handle (5) and a suspension hook (6). The technical key point is that the handle (5) and the suspension hook (6) are respectively hinged at the two end parts of a sliding sleeve (4); the balance bar (1) is arranged in the centre hole of the sliding sleeve (4); one end part of the balance bar (1) is fixedly provided with the balancing counterweight (3). The sliding type portable balance has small size and convenient carrying; the sliding type portable balance can also effectively avoid the pin match of the balance bar and the sliding sleeve and prevent illegal management.

Description

Sliding type portable balance

The utility model belongs to measurement instrument, is a kind of beam scale specifically.

The beam scale of producing at present and using all is to be made of the wooden arm beam of steelyard and sliding weight of steelyard, and the wooden arm beam of steelyard is two objects that separate with sliding weight of steelyard, and the length of the arm beam of steelyard is long, carries inconvenience.Because sliding weight of steelyard and weighing lever are separated easily, make some illegal retailers utilize the replacing of sliding weight of steelyard to carry out illegal operation in addition.

Order of the present utility model ground is in order to overcome above-mentioned deficiency, and a kind of accurate measurement that provides, plug-type portable balance easy to carry.

The utility model is achieved in that it comprises the arm beam of steelyard that is carved with the metering degree, counterweight stone roller and handle and the suspension hook that plays the sliding weight of steelyard effect, and its technical requirement is: handle and suspension hook are hinged on the both ends of a sliding sleeve respectively.The arm beam of steelyard just is installed in the center pit of sliding sleeve, can slide in the sliding sleeve center pit.An end of the arm beam of steelyard is installed with the counterweight stone roller.So just constituted plug-type portable balance described in the utility model.The principle of work of this scale is: by the slip of the arm beam of steelyard in sliding sleeve, can effectively take by weighing the weight of object.

Because portable balance of the present utility model, what adopt is the version that slide bar matches with sliding sleeve, a kind of like this scale of model just can be made a kind of slide bar and sliding sleeve fit structure of size, the scale of this version can effectively avoid the pin between the arm beam of steelyard and the sliding sleeve to join, prevent some retailer's illegal operation, in addition, the volume of this scale is little, and is easy to carry and use.

Fig. 1 is: structure principle chart of the present utility model.

The utility model is described in detail the arm beam of steelyard (1) below in conjunction with accompanying drawing: can be right cylinder, also can be square column type, and preferably right cylinder is carved with metering scale on it, so that read the weight of alleged object.The arm beam of steelyard (1) one an end counterweight stone roller of fixed installation (3) is to play the effect of counterweight.In order to enlarge the scope of weighing of this scale, the arm beam of steelyard (1) can be made into cylinder, and an additional arm beam of steelyard (2) is installed in this cylinder, and at this moment counterweight stone roller (3) is fixedly mounted on the end of the additional arm beam of steelyard (2).The inner hole section shape of sliding sleeve (4) should be identical in the cross sectional shape of the arm beam of steelyard (1), and the profile of sliding sleeve (4) can be circular, also can be square.The hinged suspension hook of the leading section of its sliding sleeve (4) (6), the hinged handle of the rearward end of its sliding sleeve (4) (5).Suspension hook (6) is to be used for hooking alleged weight.Handle (5) is the handle of mentioning scale when weighing weight.In order to guarantee the degree of accuracy of this scale, the articulated structure between suspension hook (6) and handle (5) and the sliding sleeve (4) preferably adopts the knife edge type structure.

Claims

1, plug-type portable balance, comprise the arm beam of steelyard (1), counterweight stone roller (3), handle (5), suspension hook (6), it is characterized in that: handle (5) and suspension hook (6) are hinged on the both ends of sliding sleeve (4) respectively, the arm beam of steelyard (1) is installed in the axial center hole of sliding sleeve (4), and an end of the arm beam of steelyard (1) is fixing by adorning a counterweight stone roller (3).

2, according to claim, described plug-type portable balance is characterized in that: an additional weighing lever (2) is housed in the center pit of the arm beam of steelyard (1), and counterweight stone roller (3) is fixed on an end of the additional arm beam of steelyard (2).
