Description
Technical field
The utility model relates to mechanical counter, particularly relates to a kind of lever and cam mechanism of counter.
Background technology
Mechanical counter is convenient with its counting, stable performance and be widely used in record and the display of various quantitative value without the need to the feature of electric control, therefore usable floor area is wide, market demand is larger, mechanical counter commercially available both at home and abroad is at present when producing assembling, shell is the ladle bowl shape of an integral molded plastic, be set with mutually with ladle bowl again after intraware assembles, but because its inner structure of existing mechanical counter is complicated, cause wasting time and energy and cost is larger when assembling, and the equipment price of mechanical counter is expensive, increase the cost of the manufacturing, in addition, mechanical counter, owing to lacking suitable counting gear train, cause mechanical counter self structure complexity, complex operation, and the efficiency of work is not high.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, easy to operate and be easy to the lever and cam mechanism of the counter assembled.
To achieve these goals, the utility model provides following technical scheme: the lever and cam mechanism of counter, comprise base and be located at the annular framework on base, the bottom of described annular framework is provided with the pole of reciprocally movement, described pole is hinged with ratchet, described annular framework is hinged with rotating shaft respectively, axle and fork, described rotating shaft is fixedly connected with the first gear and ratchet, described ratchet is connected with ratchet, described first gears meshing is connected with the second gear, described second gear is connected with cam by the axle be hinged on annular framework, described second gear and cam coaxial are arranged, one end of described fork is provided with rotating roller, the other end of fork is connected with counter, described roller and cam paste and touch.
The principle of this programme is such: the pole on annular framework is vertically reciprocating, due to pole being hinged with ratchet, ratchet is connected with ratchet, when pole moves back and forth, ratchet is driven to stir pawl wheel, because ratchet and the first gear are all fixed in rotating shaft, thus drive the first pinion rotation, and then the second pinion rotation of drive and the first gears meshing, because the second gear and the coaxial cam arranged all are fixed in axle, second gear driven central axis, and be with moving cam to rotate, meanwhile, paste with cam the roller touched to rotate under cam driven, make to rotate around hinge with pasting with cam the fork of roller touched, pole move through ratchet, first gear and the second gear reach on the cam affixed with the second gear, cam drives fork again, because fork is connected with counter, counter can carry out record to the number of times that pole promotes.
The utility model has the advantage of: the lever and cam mechanism of this counter, for the gear train of the counting of mechanical counter, its structure is simple, easy to operate, and is easy to the entirety assembling of mechanical counter.
Preferably, described pole is connected with cylinder, and described cylinder is fixed on base, and cylinder is arranged on base, easy installation and removal, and cylinder can drive pole reciprocatingly moving.
Preferably, described fork is connected with the extension spring be fixed on annular framework, and fork swings under the effect of cam and roller force, after turning an angle, drives fork to be returned to initial position by extension spring.
Preferably, described roller is by hinge on fork, and the bottom surface of roller and the outside surface of cam paste and touch, and by pinned connection, easy installation and removal, roller can rotate by the bearing pin on fork, and drives fork to rotate under the promotion of cam.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lever and cam mechanism embodiment of the utility model counter.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Reference numeral in Figure of description comprises: base 1, annular framework 2, pole 3, cylinder 4, ratchet 5, rotating shaft 6, fork 7, the first gear 8, ratchet 9, the second gear 10, cam 11, roller 12, counter 13, extension spring 14.
As shown in Figure 1, the lever and cam mechanism of counter, the annular framework 2 comprising base 1 and be located on base 1, the bottom of annular framework 2 is provided with pole 3, pole 3 is connected with cylinder 4, cylinder 4 is fixed on base 1, pole 3 is hinged with ratchet 5, annular framework 2 is hinged with rotating shaft 6 respectively, axle and fork 7, rotating shaft 6 is fixedly connected with the first gear 8 and ratchet 9, ratchet 9 is connected with ratchet 5, first gear 8 has been connected with a joggle the second gear 10, second gear 10 is connected with cam 11 by the axle be hinged on annular framework 2, second gear 10 and cam 11 are coaxially arranged, one end of fork 7 is provided with rotating roller 12, the other end of fork 7 is connected with counter 13, fork 7 is connected with the extension spring 14 be fixed on annular framework 2, roller 12 by hinge on fork 7, the bottom surface of roller 12 and the outside surface of cam 11 paste and touch.
In the present embodiment, pole 3 on annular framework 2 is vertically reciprocating, due to pole 3 being hinged with ratchet 5, ratchet 9 is connected with ratchet 5, when pole 3 moves back and forth, drive ratchet 5 to stir ratchet 9 to rotate, because ratchet 9 and the first gear 8 are all fixed in rotating shaft 6, thus drive the first gear 8 to rotate, and then drive the second gear 10 engaged with the first gear 8 to rotate, because the second gear 10 and the coaxial cam 11 arranged all are fixed in axle, second gear 10 drives central axis, and be with moving cam 11 to rotate, meanwhile, paste with cam 11 roller 12 touched to rotate under cam 11 drives, make to rotate around hinge with pasting with cam 11 fork 7 of roller 12 touched, pole 3 move through ratchet 9, first gear 8 and the second gear 10 reach on the cam 11 affixed with the second gear 10, cam 11 drives fork 7 again, because fork 7 is connected with counter 13, counter 13 can carry out record to the number of times that pole 3 promotes.
