Fig. 2 be the A of Fig. 1 to view, mainly express the hinged of the steelyard hook and the arm beam of steelyard;

Fig. 3 be the B of Fig. 1 to view, mainly express the installation position of pointer on the balancing arbor, escapement and hairspring;

Fig. 4 be the C of Fig. 3 to view, mainly express the fixing of hairspring and hairspring and regulate;

Fig. 5 is the D-D sectional view of Fig. 4, and the adjusting ring on expression adjuster bar and hairspring and the adjuster bar is set in the state on the hairspring outer ring.

Fig. 6 is the figure of prior art.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to Fig. 1 and Fig. 2, the arm beam of steelyard 2 right parts tops is connected with scale button 12, and arm beam of steelyard right-hand member is hinged with steelyard hook 3, and steelyard hook 3 lower ends are hinged with hook 6, and time spent hook 6 is not rotatable goes in the shell 14, is held by magnet 13.Arm beam of steelyard left part has semilune tooth plate 1, is meshed with band tooth escapement 4 on the balancing arbor 5.

Referring to Fig. 3-Fig. 5, there is pointer 8 balancing arbor 5 left parts, and there are scale face 7 and the transparent panel 10 that is loaded on the shell 14 in pointer 8 left sides.There is hairspring 9 on the right of balancing arbor 5, plays sliding weight of steelyard.Referring to Fig. 1 and Fig. 2, shell is upper right to be connected with handle 15 by pin joint 19, and handle 15 can be around point 19 half-twists to be flat on the outer casing top surface, in order to collection.After the utility model manufacturing installs, when perhaps finding that in use weighing is inaccurate, should mobile adjuster bar 11 so that the rigidity of hairspring 9 is regulated.The outer end of hairspring 9 is fixed on the stud 16, and stud 16 is fixed on the shell 14, and in the stake 17, interior stake was fixing with balancing arbor 5 in hairspring the inner was fixed in.Adjuster bar 11 left parts are for stirring handle, and middle and interior stake is connected and can be around interior stake rotation, and right-hand member has adjusting ring 18, be placed on the hairspring of outmost turns, rotate the handle of stirring of left part, make the adjusting snare the hairspring outer ring and rotate, to change the rigidity of hairspring, make it to accord with definitely exactness requirement thereby regulate weighing.

When adopting the utility model weighing material, hand-held handle is hung material on the hook 6, and the semilune tooth plate 1 of the arm beam of steelyard is around claiming that button 12 rotates up, drive escapement 4 rotations, pointer 8 counterclockwise rotates, and to indicate the weight for the treatment of the weighing material, reads outside the transparent panel 10 of this weight numerical value from shell 14, weighing finishes when needing collection, handle 15 is gone to horizontal level, and hook 6 goes back to be inhaled in the shell on magnet, can put into pocket and store.

The utility model contrast prior art has following advantage: weighing is accurate, and is easy to carry.
