Abstract
The utility model discloses an electromechanical integrated non-return meter which comprises a frame, print wheel components arranged inside the frame and a carry wheel arranged between the print wheel components, wherein, a shifting block is arranged on the side of the head wheel of the print wheel components connected with the carry wheel. The utility model is an electromechanical integrated non-return meter with simple structure and convenient use; when the head wheel of the print wheel components can not drive a middle wheel to rotate in the process of reverse shifting; the utility model overcomes the disadvantages that in the prior art, the electricity stealer can prizes up the meter cover, reversely shift the head wheel and achieve the aim of electricity stealing.
Description
Technical field
The utility model relates to a kind of electric energy register, the non-return register of especially a kind of electromechanical.
Background technology
The character wheel parts of user's electric energy register (ammeter) are made up of the first run, middle wheel, end wheel and rounding wheel at present, the first run is connected with stepper motor by train of reduction gears, the first run is stirred middle wheel by rounding wheel, and middle wheel is stirred the end wheel by rounding wheel and realized electric energy metrical.The existing first run is to block the moving tooth of rounding wheel by two shifting blocks of side, drives rounding wheel, and wheel was realized carry function successively during the moving tooth of rounding wheel drove again.It has a shortcoming, be exactly to take turns during the first run can drive just to change, wheel reversing in also driving, such design mainly is to be convenient to manufacturer before product export register is tested, regulated, but has given electricity filching person with opportunity, and electricity filching person can be pried open the table lid, fall to dial the first run, reach the stealing purpose,, all can not fundamentally prevent user's stealing though some measures of anti-stealing electricity are arranged.
Summary of the invention
The purpose of this utility model provides the non-return register of a kind of electromechanical simple in structure, easy to use, and it makes the first run of character wheel parts can not drive rounding wheel and the rotation of middle wheel when falling to dial, and has overcome the shortcoming that prior art exists.
The purpose of this utility model is achieved in that it includes framework, is installed in the character wheel parts in the framework, and the rounding wheel between the character wheel parts, and the first run of described character wheel parts is connected a side and is provided with a shifting block with rounding wheel.
Described shifting block is in the side of first run cylindrical.
Described shifting block is cylindrical.
Described shifting block is square.
Described shifting block is an involute profile.
Described shifting block is a cycloidal tooth profile.
Because the utility model has adopted said structure, compared with prior art has the following advantages: simple in structure, reliable operation; Have non-return function, can fundamentally prevent the electricity filching behavior of electricity filching person.

Among the figure: 1. framework; 2. character wheel parts; 3. rounding wheel; 4. the first run; 5. shifting block.
Embodiment
Character wheel parts of the present utility model are made up of the first run, middle wheel, end wheel and rounding wheel, the first run links to each other with stepper motor by train of reduction gears, during use, the rotation of step motor drive train of reduction gears, train of reduction gears drives first run rotation, the first run is stirred middle wheel by rounding wheel, and middle wheel is stirred the end wheel by rounding wheel and realized electric energy metrical.Wherein character wheel parts and rounding wheel all are installed in the framework, the first run of character wheel parts is connected a side and only is provided with a shifting block with rounding wheel, like this, it can stir the gear teeth of rounding wheel when just changeing, but can not touch the gear teeth of rounding wheel during reversing, rounding wheel is rotated, make register play thief-proof function.Wherein shifting block is in the side of first run cylindrical, can make cylindrical, square, involute profile, cycloidal tooth profile or other shape.
