Abstract
The utility model relates to a counter of a character wheel type electric energy meter, comprising a step motor, a reducing mechanism, a character wheel frame body and each print wheel. Wheel face of each character wheel is widened, inner gear teeth are arranged on one side of surface of an inner ring of each print wheel, a set of carry teeth are arranged on the other side of the surface of the inner ring, a thin holding frame is arranged among each character wheel, the holding frame is a wafer body the size of which is same with the size of the outer margin of the character wheel, an outer convex sheet is integrally connected with one side of each holding frame, the center of the wafer body of each holding frame and the character wheels are sheathed on a print wheel shaft together, and through holes on the outer convex sheet of each holding frame are all sheathed on a locating shaft which is positioned at a corresponding position of a character wheel frame body. The carry wheels which are engaged with wheel teeth of the inner ring of the corresponding character wheel are movably connected with positions which correspond with the wheel teeth on the surface of the inner ring of each character wheel of each holding frame, and the wheel teeth of each carry wheel are engaged and connected with the carry teeth arranged on the corresponding side of the surface of the inner ring of the next character wheel simultaneously.
Description
The utility model relates to a kind of character wheel formula Electric energy meter KWh counter.
Character wheel structure in the Electric energy meter KWh counter is open at present, its drive mechanism is the structure of hexagonal power wheel in the character wheel outside, because electric energy meter is to the requirement of register volume and the restriction of stepper motor starting torque, so character wheel can not design very greatly, owing to adopt outside hexagonal power wheel structure,, make that the character wheel volume is littler between character wheel and the character wheel so must leave big gap between them, and the volume of character wheel is too little, is restricted to the size that makes character wheel thermoprint character code.Thereby the registration that makes electric energy meter all can need at any time in actual use to check character code becomes comparatively inconvenient.
The purpose of this utility model is exactly in order to address the above problem, and a kind of enclosure-type character wheel Electric energy meter KWh counter that as far as possible increases the character wheel volume under the condition that does not strengthen existing register volume is provided.
Technical solution of the present utility model:
A kind of enclosure-type character wheel Electric energy meter KWh counter, it includes stepper motor, reducing gear, character wheel framework and each character wheel, stepper motor links to each other with the character wheel framework by reducing gear, each character wheel kink is on the print wheel shaft that is arranged at character wheel framework center, the wheel face that it is characterized in that each character wheel is widened, make that the gap is very little between them, each character wheel inner peripheral surface one side is equipped with the interior gear teeth, its inner peripheral surface opposite side is equipped with a group carry tooth, be provided with slim retainer between the little gap between each character wheel, retainer is and the identical wafer body of character wheel outer rim size, the equal integral body of each retainer one side is connected with outer lug, each retainer wafer body center and character wheel together are sleeved on the print wheel shaft, and the through hole on the outer lug of each retainer all is sleeved on the locating shaft that is arranged at character wheel framework correspondence position, the correspondence of each retainer separately the equal activity in position of the character wheel inner peripheral surface gear teeth be connected with rounding wheel with corresponding character wheel inner ring tooth mesh, and the gear teeth of each rounding wheel are connected with a joggle with the carry tooth of the corresponding side of adjacent character wheel inner peripheral surface simultaneously.
The utility model has strengthened the width of character wheel under the situation that does not increase volume of register own and character wheel weight, the interior limited space of Electric energy meter KWh counter is fully utilized, can strengthen character wheel very effectively can make the contradiction of big character code and volume and character wheel weight be able to good solution for the area of thermoprint character code.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A diagrammatic cross-section of Fig. 1;
Fig. 3 is the reverse side synoptic diagram of Fig. 2.
As Fig. 1-3, the utility model includes stepper motor 1, reducing gear 2, character wheel framework 3 and each character wheel 4, stepper motor 1 links to each other with character wheel framework 3 by reducing gear 2, each character wheel 4 kink is on the print wheel shaft 5 that is arranged at character wheel framework 3 centers, characteristics of the present utility model are, the wheel face of each character wheel 4 is widened, make that the gap is very little between them, to increase the stamping face of character wheel 4 numerals, each character wheel 4 inner peripheral surface one side is equipped with the interior gear teeth 6, its inner peripheral surface opposite side is equipped with a group carry tooth 7, be provided with slim retainer 8 between the little gap between each character wheel 4, make them form a hermetically sealed character wheel, retainer 8 is and the identical wafer body of character wheel 4 outer rims size, the equal integral body of each retainer 8 one side is connected with outer lug 9, each retainer 8 wafer body center and character wheel 4 together are sleeved on the print wheel shaft 5, and the through hole on the outer lug 9 of each retainer 8 all is sleeved on the locating shaft 10 that is arranged at character wheel framework 3 correspondence positions, the correspondence of each retainer 8 separately the equal activity in position of the character wheel 4 inner peripheral surface gear teeth 6 be connected with rounding wheel 11 with 6 engagements of the corresponding character wheel 4 inner ring gear teeth, and the gear teeth of each rounding wheel 11 are connected with a joggle with the carry tooth 7 of the corresponding side of adjacent character wheel 4 inner peripheral surface simultaneously.
In the utility model, the rounding wheel 11 that is arranged on the retainer 8 can realize that the correspondence position at each retainer 8 edge is equipped with little minor axis 12 by following structure, each rounding wheel 11 with regard to movable set on little minor axis 12 separately.
Drive mechanism between each character wheel 4 of the utility model be rounding wheel 11 kinks on the retainer 8 that is installed between the character wheel 4, and the transmission gear teeth 6 on the character wheel 4 and carry tooth 7 hidden inboards at character wheel 4.No tangible gap between character wheel 4 and the character wheel 4 forms the enclosure-type character wheel.It is that locating shaft 10 is used for limiting retainer 8 that a fulcrum is arranged in the outside of character wheel 4, makes it can not follow character wheel 4 and rotates.
The utility model principle of work is as follows, when driving the first character wheel 4 by reducing gear 2, stepper motor 1 rotates, when these first place character wheel 4 carries, the carry tooth 7 of its inner peripheral surface one side drives rounding wheel 11 actions on its retainer 8, this rounding wheel 11 is because 6 engagements of simultaneously corresponding with adjacent next bit character wheel 4 an inner peripheral surface side wheel tooth, so its rotation drives the character wheel 4 of adjacent next bit simultaneously and rotates, and finishes the carry action, below analogizes.
