Abstract
The utility model discloses a novel water meter print wheel box comprising a print wheel shaft, a print wheel, a liquid seal cavity, a bottom cavity which is arranged at the bottom of the print wheel box, and two opto-electrical module circuit boards; one end of the bottom cavity is provided with a side cavity which is communicated with the bottom cavity; and one opto-electrical module circuit board is arranged in the bottom cavity, and the other opto-electrical module circuit board is longitudinally arranged in the side cavity. By adopting the structure, the novel water meter print wheel box has the advantages that: 1. because the bottom cavity and the liquid seal cavity are two mutually independent cavities, wherein the liquid seal cavity is sealed and can prevent air from entering and producing bubbles; and 2. compared with the prior art in which the two opto-electrical module circuit boards are horizontally arranged at the bottom of the print wheel box, the longitudinal setting of one opto-electrical module circuit board in the side cavity reduces the bottom thickness of the print wheel box, so that the print wheel box can be compatible with a traditional water meter cassette mechanism, and the applicability is improved.
Description
Technical field
The utility model relates to water meter dial plate technical field, particularly a kind of new water meter character wheel box.
Background technology
At present, the character wheel box of liquid sealing photoelectric direct-reading remote transmitting water meter divides two kinds substantially:
A kind of is that number of patent application is offering in order to the separate sides chamber of optical-electric module to be set in that fluid-tight character wheel box is other of putting down in writing of 200910184220.3 patent document, and optical-electric module is inserted in the separate sides chamber.Be opened in any side of the both sides parallel with fluid-tight character wheel box print wheel shaft in order to the separate sides chamber that optical-electric module is set.By offering the side chamber on fluid-tight character wheel box side, optical-electric module is placed in the separate chamber, make it to break away from fully liquid environment, be subjected to protection effectively; Simultaneously, optical-electric module is arranged on the side position of character wheel box, can make it not influence the demonstration of character wheel box character wheel.This water meter character wheel box, owing to must fill liquid in the cavity of liquid-sealing water meter, and this cavity can't guarantee absolute sealing, has air usually to enter, and will produce small bubble like this in cavity; Add that this photo-electronic directly reading water meter is that transmission by photoelectric tube light comes recognizing site, and the position of the photoelectric tube position consistency floating with bubble, add that cavity space is narrow and small, be easy to cause the bubble retaining between photoelectric tube and character wheel, bubble can cause light refraction, will produce like this and set positional fault, make final error in reading, there is very big hidden danger in this utility model structure.
Another kind is that the patent No. is a kind of direct readable modus ponens character wheel box that 200520013528.9 Chinese patent is put down in writing, the digit wheel and the data collector that are stringed together by print wheel shaft are installed in the box body, the integrated groove that two parts are isolated mutually about on the described box body central bottom plane there being design, the character wheel groove of dress digit wheel in top groove branch is separated with, rounding wheel also is housed between each character wheel, the data collector of being made up of photocoupler and electronic circuit board is housed in the groove of lower part, the wiring board of described photocoupler directly is inserted in the middle of the digit wheel side of top groove, it has rational in infrastructure, easy to install, guarantee characteristics such as signal stabilization.This structure is because the restriction in space, the limitation of wiring board size, cause bottom space to increase downwards, just can guarantee the wiring board sealing is annotated, character wheel box after increasing just can't be compatible mutually with traditional water meter movement, cause the movement and the housing that match with it to customize, cause the increase of cost.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, a kind of new water meter character wheel box is provided, bubble occurs in the fluid-tight chamber of avoiding the box-packed liquid of character wheel and reduce character wheel box bottom thickness to reach, thereby make the widely applicable purpose of character wheel box.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of new water meter character wheel box, comprise print wheel shaft, character wheel, be equipped with liquid the fluid-tight chamber, be arranged on chamber, the end, two optical-electric module wiring boards of character wheel box bottom, one end in chamber, the described end is provided with the side chamber that is connected with chamber, the end, described two optical-electric module wiring boards wherein one be arranged in the chamber, the end, another piece vertically is arranged in the side chamber.
Described side chamber is straight chamber.
Optical-electric module wiring board in the chamber, the described end is for being horizontally disposed with, and described two optical-electric module wiring boards are vertical mutually the setting.
The utility model adopts said structure, has the following advantages: 1, because chamber, the end and fluid-tight chamber are two separate cavitys, the fluid-tight chamber is what seal, so can avoid air to enter the generation bubble; 2, all be horizontally set on the bottom of character wheel box than two optical-electric module wiring boards in the past, vertical setting of an optical-electric module wiring board in the side chamber, reduced character wheel box bottom thickness, thereby made the character wheel box can be compatible mutually, increased its applicable surface with traditional water meter movement.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a structural representation of the present utility model;
In Fig. 1,1, print wheel shaft; 2, character wheel; 3, fluid-tight chamber; 4, chamber, the end; 5, optical-electric module wiring board; 6, side chamber.
Embodiment
A kind of as shown in Figure 1 new water meter character wheel box, comprise print wheel shaft 1, character wheel 2, the fluid-tight chamber 3 of liquid, the chamber, the end 4 that is arranged on character wheel box bottom, two optical-electric module wiring boards 5 are housed, one end in chamber, the end 4 is provided with the side chamber 6 that is connected with chamber, the end 4, two optical-electric module wiring boards 5 wherein one be arranged in the chamber, the end 4, another piece vertically is arranged in the side chamber 6.Side chamber 6 is straight chamber.
Optical-electric module wiring board 5 in the chamber, the end 4 is for being horizontally disposed with, and described two optical-electric module wiring boards 5 are vertical mutually the setting.The module by signal line of optical-electric module wiring board 5 leads to outside the box.
Because chamber, the end 4 is two separate cavitys with fluid-tight chamber 3, the fluid-tight chamber is what seal, so can avoid air to enter the generation bubble.All be horizontally set on the bottom of character wheel box than two optical-electric module wiring boards 5 in the past, vertical setting of side chamber 6 interior optical-electric module wiring boards 5, reduced character wheel box bottom thickness, thereby made the character wheel box can be compatible mutually, increased its applicable surface with traditional water meter movement.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
