Description

The metal steelyard

The utility model belongs to the weighing apparatus of a kind of suitable family and market use.

At present, the employed traditional wood steelyard of people adopts all the time and makes by hand, can not realize standard batch production, when bearing heavier load, is easier to flexural deformation, influence metering sensitivity.Simultaneously, client is when shopping, and arm beam of steelyard displayed value both sides can not see simultaneously that retailer who has even the trick of adopting a scale two to cut or polish jade with an emery wheel tip the customers

The purpose of this utility model is to provide an a kind of scale two stone roller disadvantages, metal steelyard that arm beam of steelyard displayed value master, objective both sides can see simultaneously of preventing.

The utility model is a kind of metal steelyard, mainly by the hook thing edge of a knife, and the portable edge of a knife, sliding weight of steelyard, the arm beam of steelyard, steelyard hook or the scale pan are formed, and the arm beam of steelyard adopts the structure of three grooves, all is inlaid with the metering scale in the groove, and sliding weight of steelyard matches with the arm beam of steelyard, moves about on the arm beam of steelyard.Simultaneously, the metering length of the scale that is positioned at forward and backward groove is equal, the scale correspondence, its graduation apparatus is shown the maximum weighing of zero point to ten/three, be positioned at the metering scale of end face groove, its graduation apparatus is shown 3/10ths to maximum weighing, and the arm beam of steelyard can adopt aluminum alloy materials to make.Sliding weight of steelyard (4) structure then can be divided into upper and lower two parts, between the two by being threaded, and is provided with rivet at the upper and lower two parts of sliding weight of steelyard.

After the arm beam of steelyard described in the utility model adopts three grooves and inlay the structure of metering scale in groove, solved the problem that weighing displayed value master, objective both sides can not see simultaneously effectively, whether the scale of metering scale also or not be not worn simultaneously, and the arm beam of steelyard adopts aluminum alloy materials to make, thereby rigidity is better than wood steelyard, and the metering displayed value is accurate.And sliding weight of steelyard adopts the sliding weight structure that matches with the arm beam of steelyard, moves about on the arm beam of steelyard, simultaneously by the screw thread rotation between the upper and lower two parts of sliding weight of steelyard, can block the arm beam of steelyard in any scale mark position, realizes self-locking.In addition, be provided with rivet, thereby make sliding weight of steelyard be difficult for being removed, solved the disadvantage of a scale two stone rollers at the upper and lower two parts of sliding weight of steelyard.

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

Fig. 1 is the utility model one-piece construction synoptic diagram;

Fig. 2 is an arm beam of steelyard A-A cutaway view Amplified image described in the utility model;

Fig. 3 is that the arm beam of steelyard described in the utility model cooperates cutaway view Amplified image with sliding weight of steelyard B-B.

The utility model is a kind of steelyard, mainly by the hook thing edge of a knife (1), and the portable edge of a knife (2), the portable edge of a knife (3), sliding weight of steelyard (4), the arm beam of steelyard (5), the steelyard hook (9) or the scale pan (10) are formed, and the steelyard hook (9) or the scale pan (10) can be changed at any time according to the body form difference.The arm beam of steelyard (5) can adopt aluminum alloy materials to make, and adopt forward and backward, the top three grooves structure, in the forward and backward groove of the arm beam of steelyard (5), be inlaid with two for marking metering scale (6), (8) of reading value, metering scale (6), (8) equal in length, the calibration of groove is corresponding one by one, and top graduation apparatus is shown the maximum weighing of zero point to ten/three.Then be inlaid with metering scale (7) at the arm beam of steelyard (5) end face, the scale on it then is expressed as 3/10ths weighings to maximum weighing.The maximum weighing of for example whole steelyard is as being decided to be 5 kilograms, and then the metering scale (6) in the groove of front and back, the weight that (8) can show are 0 kilogram to 1.5 kilograms.And the weight that metering scale (7) can show is 1.5 kilograms to 5 kilograms.Sliding weight of steelyard (4) matches with the arm beam of steelyard (5), moves about on the arm beam of steelyard (5).Itself is made up of sliding weight of steelyard (4) upper and lower two parts sliding weight of steelyard again, links by screw thread (11) between the two, after the connection, along screw thread (11) rotation, sliding weight of steelyard (4) can block the arm beam of steelyard (5) at arbitrary scale, realizes self-locking, the negative side rotation, then sliding weight of steelyard (4) can move about in the optional position of the arm beam of steelyard (5) again.In addition, be provided with rivet (12), thereby sliding weight of steelyard (4) can not arbitrarily be taken off from the arm beam of steelyard (5) at the upper and lower two parts of sliding weight of steelyard (4).

During the scale thing, the front end of sliding weight of steelyard (4) aligns with zero graduation on metering scale (6), (8), and the utility model is in equilibrium state.After hanging up weight, mobile sliding weight of steelyard (4) is to the position of required balance again, when weight weight maximum weighing 3/10ths in the time, the scale mark position of sliding weight of steelyard (4) front end of metering scale (6), (8) last correspondence is the reading of weight weight, when weight weight surpasses 3/10ths maximum weighings, by the conversion of the portable edge of a knife (2) or (3), measure scale (7) and go up the reading that the scale mark position of corresponding sliding weight of steelyard (4) front end is weight weight.When needs claim thing by fixed weight, need only move to the arm beam of steelyard (5) position of expression fixed weight reading to sliding weight of steelyard (4), by the upper and lower two-part screw thread of sliding weight of steelyard (4) (11) rotation, block the arm beam of steelyard (5) and get final product then.

Certainly, the utility model scope required for protection is not limited only to the described scope of the foregoing description, and the arm beam of steelyard (5) also can adopt two grooves and inlay the structure of metering scale in groove, and this all belongs to the utility model scope required for protection.
