Description

Hand pulse producer

Technical field

The utility model relates to hand pulse producer technical field, especially a kind of hand pulse producer of long service life.

Background technology

At present, hand pulse producer on the market is varied, wherein the range of application of hand pulse producer is also very extensive, yet the inner core screw of the hand wheel handle of existing hand pulse producer leaks outside, and people are seen, influences integrally-built attractive in appearance, especially handwheel fine setting ring gear is old outer ring gear of tradition and spring leaf combination always, the long-term structure problem of receiving spring leaf that uses can not return to the position of former designing requirement, thereby makes the lost of life of machinery.

The utility model content

The technical problems to be solved in the utility model is: the hand pulse producer that a kind of long service life is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of hand pulse producer, has handwheel, hand wheel handle, main body, main shaft, handwheel is provided with index dial, the main shaft that is driven by handwheel interts on the center pit of main body, cavity between handwheel and the main body partly is provided with locating device, main shaft is fixed with grating away from an end of handwheel, locating device comprises the ring gear that is fixed on the main body, be fixed with rotary disk on the main shaft in the ring gear, offer radial hole on the rotary disk, be provided with spring in the radial hole, the spring front end is provided with the ball that is partially submerged into the ring gear teeth groove, and hand wheel handle comprises the shell of an end opening, gib screw and lining, gib screw pass bush threads and are connected on the handwheel, the inner ring clearance fit of gib screw and lining, the outer ring of lining and shell inner ring closely cooperate, and main body is provided with annular guard ring near the position of index dial, and long-term use can return to intrinsic requirement, increase the service life, practical and convenient.

The beneficial effects of the utility model are, hand pulse producer of the present utility model, and good looking appearance is generous, its long service life.
