Abstract
The utility model relates to a pointer swing mechanism of an air-pressure gage movement, which comprises a balance staff which is arranged on the upper portion of a movement base, an upper clip, and a lower clip, a cycloidal gear assemblage which is constituted by a fan gear and a shaft gear is arranged between the upper clip and the lower clip, and the shaft gear is connected with a gear shaft which is equipped with balance springs, and the upper clip which traverses from the gear shaft is connected with the pointer. The balance, the upper clip, the lower clip, the fan gear, and the shaft gear take symmetrical arrangement, positions which are mutually assembled are on the same central line. Because the utility model adopts structures that the he balance, the upper clip, the lower clip, the fan gear, and the shaft gear take symmetrical arrangement, and the positions which are mutually assembled are on the same central line, therefore, errors which are caused by offsets and mounting and adjusting after the relative fitting parts are mutually assembled in the prior art are overcome, the precision and stability of the movement are further improved, and the T-shaped three-point location of the lower clip can assure stability of integral work after being used for a longer time.
Description
Technical field
The utility model relates to a kind of instrument, particularly a kind of beat of pointer mechanism of reflecting the weather atmospheric value with the air pressure meter movement.
Background technology
As everyone knows, air pressure mainly is made up of critical pieces such as core of pressure meter, watchcases, inventor's patent No. is 200420072016.5,200620053520.X, invention and created name is two patents of " a kind of rain glass movement ", though it is different on the structure of integral body table movement, but its main order ground still is for the reliability and the accuracy of the use that improves whole movement, continuous aggravation and popularization and application along with the instrument industry competition, reflect real-time pressure accurately, improving the precision of movement, has been one of the sector technician urgent problem.
The utility model content
Technology to be solved in the utility model is: provide a kind of rationality from each modular construction design of movement to make the movement work beat of pointer more accurate, air pressure meter movement accurately mechanism.
The technical solution of the utility model is: a kind of beat of pointer mechanism of air pressure meter movement, comprise the balance staff that is arranged on the core base top, train wheel bridge, lower plate, last, be provided with between the lower plate by elevating arc, the cycloid tooth wheels that shaft gear is formed, the tail end of this elevating arc and last, set rotating shaft is driven mutually and is connect between the lower plate, above-mentioned shaft gear is connected with the tooth axle that hairspring is housed, the upper end of described tooth axle passes train wheel bridge and links to each other with pointer, be characterized in above-mentioned balance staff, train wheel bridge, lower plate, elevating arc, shaft gear is symmetric configuration, and the position after assembling mutually therebetween is on same center line.
Further: above-mentioned lower plate is the T type of the two ends band wing, is provided with the lower supporting rod that installs mutually with core base at the edge of the two ends wing.
Further: above-mentioned train wheel bridge is made of a pair of U type clamping plate, is respectively equipped with therebetween for the upper supporting column that is connected with lower plate.
The utility model is owing to adopted balance staff, train wheel bridge, lower plate, elevating arc, shaft gear to be set to symmetric configuration and the mutual version that is in its position after the assembling on the same center line; overcome in the prior art each correlated parts and assembled the back mutually because of biasing; the error that Installation and Debugging bring; the precision and the accuracy of movement work have further been improved; and lower plate is the three-point fix of T type, can guarantee the stability of movement overall work after using the long period.In addition, train wheel bridge is made as clamping plate by a pair of U type, can further reduces production costs, in order to the competition in market.
