Description
Technical field
The utility model relates to the technical field of medicine equipment, especially a kind of high precision scale.
Background technology
Scale is a kind of instrument utilizing the lever balance theory of Hooke's law or power to measure mass of object, and it forms primarily of load bearing system, power transmission converting system and indicating value system three part.
But usually adopt two springs in the power transmission converting system in existing most scale, the problem faced by reality is: 1, due to material reason, two springs equally in actual production, can not be produced; 2, due to processing aspect, the length of two springs also can not be duplicate.Above 2 problems just may cause two spring stress inequalities under service condition, and the deformation of generation is just inaccurate, cause weighing inaccurate; Also have one often may to use due to unbalance stress, a stressed larger spring is easily tired, cause scale to lose efficacy.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of high precision scale, only adopts a spring in its power transmission converting system.
The utility model solves the technical scheme that its technical matters adopts: a kind of high precision scale, there is scale body base, the upper surface of described scale body base is provided with table top and is positioned at the column in table top front, the top of described column is provided with dial plate seat, described dial plate seat is provided with and looks face index dial, the inside of described scale body base is provided with long bridge and is arranged on the minibridge on long bridge; The inside of described column is provided with transmission rod, is arranged on the spring fixed seat on transmission rod top and is arranged on a spring on spring fixed seat, and the bottom of described transmission rod is connected with the front end of long bridge; The inside of described dial plate seat is provided with tooth bar, by its gear shaft rotated of rack drives and the pointer be arranged on gear shaft, described tooth bar is connected with the top of spring, and described pointer is positioned at the upper surface looking face index dial.
Further, the column described in technique scheme is square tube column or pipe column or oval-shaped upright posts.
The beneficial effects of the utility model are: a kind of high precision scale of the present utility model, only a spring is adopted in power transmission converting system wherein, to overcome in prior art the deformation that two springs produce because of unbalance stress in actual use to be forbidden, and then occur weighing inaccurate problem, also overcoming in prior art two springs because of unbalance stress makes a stressed larger spring easily tired after often using, and then the problem causing scale to lose efficacy, make the measuring accuracy of whole scale more accurate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of power transmission converting system in scale.
Label in accompanying drawing is: 1, scale body base, 2, table top, 3, column, 4, dial plate seat, 5, look face index dial, 6, Chang Qiao, 7, minibridge, 8, transmission rod, 9, spring fixed seat, 10, spring, 11, tooth bar, 12, gear shaft, 13, pointer.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of high precision scale as depicted in figs. 1 and 2, there is scale body base 1, the upper surface of scale body base 1 is provided with table top 2 and is positioned at the column 3 in table top 2 front, column 3 is square tube column or pipe column or oval-shaped upright posts etc., the top of column 3 is provided with dial plate seat 4, dial plate seat 4 is provided with and looks face index dial 5, the inside of scale body base 1 is provided with long bridge 6 and the minibridge 7 be arranged on long bridge 6; The inside of column 3 is provided with transmission rod 8, is arranged on the spring fixed seat 9 on transmission rod 8 top and is arranged on a spring 10 on spring fixed seat 9, and the bottom of transmission rod 8 is connected with the front end of long bridge 6; The pointer 13 that the inside of dial plate seat 4 is provided with tooth bar 11, the gear shaft 12 driving it to rotate by tooth bar 11 and is arranged on gear shaft 12, tooth bar 11 is connected with the top of spring 10, and pointer 13 is positioned at the upper surface looking face index dial 5.
The principle of work of this scale is: stand in the acting force that the body weight of people on table top 2 is downward because gravity produces, this acting force is applied on long bridge 6 and minibridge 7, this acting force be subject to is transferred to spring 10 by the transmission rod 8 being connected to its front end by long bridge 6, the tooth bar 11 that spring 10 top connects produces sagittal motion, the front and back of tooth bar 11 are rotated to Sports band movable gear shaft 12, and the pointer 13 be arranged on immediately on gear shaft 12 realizes digitized weighing under the rotation of rule.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
