Abstract
The utility model relates to a thermometer, which comprises a thermometer shell and a graduated circle which is located in the thermometer shell, and also comprises a zero setting device of the graduated circle. The zero setting device of the graduated circle comprises a driving device which is used to rotate the graduated circle and an adjusting part which is used to drive the driving device, wherein the adjusting part is connected with the driving device, and the driving device is connected with the back of the graduated circle. When an indicating needle on the graduated circle is deviated from a zero point, the indicating needle can be set to the zero point through the adjusting part freely. Errors due to the indicating needle which is not set on the zero point can not be brought to data measurement, and the accuracy of the data measurement can be improved.
Description
(1) technical field
The utility model relates to a kind of thermometer, especially a kind of thermometer that balancing controls are arranged.
(2) background technology
Present thermometer does not all have certain balancing controls, and therefore after having used a period of time, its pointer may depart from the position at zero point because of use repeatedly.Bring very big error can for so later measurement data, greatly reduce the accuracy of data.
(3) utility model content
Can't realize the deficiency of graduation apparatus zeroing for overcoming existing thermometer, the utility model provides a kind of thermometer that balancing controls are arranged that can improve measurement accuracy greatly.
The technical scheme in the invention for solving the technical problem is: a kind of thermometer, the index dial that comprises watchcase and be positioned at described watchcase, wherein also comprise the index dial balancing controls, these index dial balancing controls comprise the adjusting portion that is used to rotate the gearing of described index dial and is used to drive described gearing, described adjusting portion is connected with described gearing, and described gearing is connected with the back side of index dial.After thermometer repeatedly uses, needle deflection during null position, can drive gearing and rotate by the adjusting of adjusting portion, thereby rotary dial reaches the purpose of pointer zeroing.
The above-mentioned gearing that is used to drive can be gear drive comprise driving gear, with the follower gear of described driving gear engagement, the center of described driving gear is provided with adjusting screw(rod), the afterbody of this adjusting screw(rod) is positioned at outside the described watchcase.
The above-mentioned gearing that is used to drive can also be that the belt wheel transmission comprises driving pulley, the driven pulley that is connected with described driving pulley, and the center of described driving pulley is provided with adjusting screw(rod), and the afterbody of this adjusting screw(rod) is positioned at outside the described watchcase.
The beneficial effects of the utility model are: when the pointer on the index dial when departing from zero point, can at will pointer be returned to zero by adjusting portion.The error that bring pointer not make zero can not for the data that will measure and bring has improved the accuracy of measurement data.
(4) description of drawings
Fig. 1 is a side view of the present utility model.
Fig. 2 is the inner structure synoptic diagram of watchcase.
(5) embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, Fig. 2, a kind of thermometer, the index dial 2 that comprises watchcase 1 and be positioned at described watchcase 1, also comprise the index dial balancing controls, these index dial balancing controls comprise the adjusting portion that is used to rotate the gearing of described index dial 2 and is used to drive described gearing, described adjusting portion is connected with described gearing, and described gearing is connected with the back side of index dial 2.In the present embodiment, described gearing comprise driving gear 3, with the follower gear 4 of described driving gear 3 engagements, the center of described driving gear 3 is provided with adjusting screw(rod) 5, and this adjusting screw(rod) 5 constitutes the adjusting portion of gearing, and the afterbody of described adjusting screw(rod) 5 is positioned at outside the described watchcase 1.
When the pointer on the index dial when departing from zero point, thereby can drive driving gears 3 and rotate by rotating adjusting screw(rod) 5, thereby drive follower gear 4 and rotate, index dial 2 is rotated, until zeroing.Certainly, the described gearing that is used for rotary dial can also be taked other feasible modes, reach the purpose that the temperature pointer on the final index dial makes zero, gearing as described comprises driving pulley, the driven pulley that is connected with described driving pulley, the center of described driving pulley is provided with adjusting screw(rod), and the afterbody of this adjusting screw(rod) is positioned at outside the described watchcase.
Claims (3)
1. thermometer, the index dial that comprises watchcase and be positioned at described watchcase, it is characterized in that: also comprise the index dial balancing controls, these index dial balancing controls comprise the adjusting portion that is used to rotate the gearing of described index dial and is used to drive described gearing, described adjusting portion is connected with described gearing, and described gearing is connected with the back side of index dial.
2. a kind of thermometer as claimed in claim 1, it is characterized in that: described gearing comprise driving gear, with the follower gear of described driving gear engagement, the center of described driving gear is provided with adjusting screw(rod), and the afterbody of this adjusting screw(rod) is positioned at outside the described watchcase.
