Detailed Description

The present invention will be further explained with reference to the following drawings and examples:

in the embodiment, as shown in fig. 1 and 2, the pressure gauge with an improved structure comprises a panel 1, wherein a spring tube 2 and a sector gear 3 are installed on the panel 1, a connecting portion 4 is arranged at one end of the spring tube 2, a waist hole 5 is arranged on the connecting portion 4, and a connecting column 6 matched with the waist hole 5 is arranged at one end of the sector gear 3. Through the cooperation of the connecting column 6 and the waist hole, the spring tube 2 is connected with the sector gear 3, and a connecting rod connecting piece is omitted, so that the assembly is simple, the realization of automatic assembly is facilitated, and meanwhile, the production cost is reduced.

In the embodiment, the connecting portion 4 and the spring tube 2 are in welded fit. The connecting part 4 and the spring tube 2 are integrated, the overall performance is good, and meanwhile the sealing performance of the joint of the connecting part 4 and the spring tube 2 is good.

In an embodiment, the connecting column 6 and the sector gear 3 are in riveted fit. The process is simple, the connection between the connecting column 6 and the sector gear 3 is reliable, and meanwhile, the connecting column 6 has better shock resistance.

In the embodiment, as shown in fig. 2, the gear ratio of the sector gear 3 to the sun gear 7 is 7. The gear ratio 74 of the existing sector gear and sun gear, the optimal gear ratio 82 of the sector gear 4 and sun gear 7 of the present application, is used to reduce the displacement of the spring tube 2 and improve the service life of the spring tube 2.

In the embodiment, as shown in fig. 2, 3 and 4, the watch further comprises a dial plate 8 mounted on the face plate 1, the face plate 1 is provided with a hollow column 9, and the back of the dial plate 8 is provided with a plug-in part 10 matched with the hollow column 9. Dial plate 8 need not to be connected with panel 1 through the connecting piece, 8 easy dismounting of dial plate.

In the embodiment, as shown in fig. 2 and 3, the hairspring further comprises a hairspring 11 mounted on the face plate 1, the hollow columns 9 are located on two sides of the hairspring 11, and the hollow columns 9 are provided with clamping grooves 12 matched with the hairspring 11. Be equipped with the interval between draw-in groove 12 and panel, draw-in groove 12 is used for fixed hairspring 11 to make hairspring 11 and panel 1 leave the determining deviation simultaneously, guarantees the stability of hairspring 11 structure, ensures the rotatory stability of pointer on the manometer.
