Abstract
The utility model relates to a numeral wheel type counter for gas meters, which comprises a counter rack 1, a numeral wheel 6, a counter seat 10, a shaft gear 2, a gear 3, and a transmission gear 4, wherein, the numeral wheel comprises a premier numeral wheel 5; one end of a transmission shaft of the transmission gear is in an open elastic clamping form, the transmission gear is in expanding-joint with the gear, and the gear can be conveniently discharged to change to fit gas of different specifications. The utility model has the advantages of simple structure, strong versatility, etc. The utility model is suitable to use with gas meters in the series of 2.5 < 3 >-250 <3>.
Description
The utility model relates to a kind of counter, particularly a kind of mechanical character wheel formula counter.
Existing character wheel formula counter, because its gear and power wheel are to be fixed on one by power axle, thereby the gear ratio of gear and axle tooth immobilizes, after so counter is carried out, just determined to adapt to the gas meter of much flows relatively, and because two positioning ports of its counter seat be the closed type structure entirely, also influence it and install, dismantle and the versatility of each gas meter.
The purpose of this utility model designs a kind of simple in structure exactly, and is easy for installation, can adapt to 2.5
3～250
3The character wheel formula counter of gas meter series.
The purpose of this utility model realizes by following structure: gas meter includes counter frame and character wheel and axle tooth, gear, driving cog etc. with character wheel formula counter, its principal character is: it also includes counter seat, in character wheel, include the first character wheel, and the transmission shaft end of driving cog is an opening elasticity card shape, make gear and rotary shaft end form expanded joint, so that can be convenient for changing gear according to the gear needs of different size gas meter.
The utility model compared with prior art has advantage simple in structure, easy to use, especially can be convenient for changing gear to satisfy the requirement of different size gas meter to gear, has enlarged the usable range of this counter.
Description of drawings of the present utility model is as follows:
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is a sectional side view of the present utility model.
Among the figure: 1, counter, 2, the axle tooth, 3, gear, 4, power wheel, 5, the first character wheel, 6, character wheel, 7, steamboat, 8, print wheel shaft, 9, back-up ring, 10, counter seat, 11, steady arm, 12, power axle, 13, the opening positioning port, 14, scale.
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1: the utility model includes counter frame 1 and character wheel 6, axle tooth 2, gear 3, driving cog 4, it is characterized in that: further comprising has counter seat 10, includes the first character wheel 5 in character wheel, and the axle head of the power axle 12 of driving cog is an opening elasticity card shape, make gear and transmission axle head expanded joint, as shown in Figure 2; More convenient for this counter is installed, to adapt to the installation requirement of different size gas meter, a positioning port of counter seat is an opening positioning port 13.For the precision that makes gas meter is higher, drawing on the first character wheel has scale 14.
