Abstract
The invention discloses a character wheel box of a water meter, which comprises a character wheel shaft, a character wheel, a liquid seal chamber containing liquid, a bottom cavity reserved at the bottom of the character wheel box and two photoelectric module circuit boards, wherein one end of the bottom cavity is provided with a side cavity communicated with the bottom cavity; and one of the two photoelectric module circuit boards is arranged in the bottom cavity, while the other is longitudinally arranged in the side cavity. The character wheel box with the structure has the advantages that: 1, as the bottom cavity and the liquid seal cavity are independent from each other and the liquid seal cavity is sealed, air cannot enter to produce bubbles; and 2, compared with the prior art in which the two photoelectric module circuit boards are both horizontally arranged at the bottom of the character wheel box, one of the two photoelectric module circuit boards of the character wheel box is longitudinally arranged in the side cavity to reduce the thickness of the bottom of the character wheel box, so that the character wheel box can be compatible with the movement of the conventional water meter and has an expanded application range.
Description
Technical field
The present invention relates to water meter dial plate technical field, particularly a kind of 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.Through 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, received 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 get into, and will in cavity, produce small bubble like this; Add that this photo-electronic directly reading water meter is that transmission through photoelectric tube light comes recognizing site; And the position of the photoelectric tube position consistency floating with bubble adds that cavity space is narrow and small, is 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 invention 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 each other about being designed with on the described box body central bottom plane; 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, guarantees 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, the 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.
Summary of the invention
Technical matters to be solved by this invention is, to the deficiency of prior art, a kind of water meter character wheel box is provided, and bubble occurs in the fluid-tight chamber of avoiding the box-packed liquid of character wheel and reduces 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; Technical scheme of the present invention is: a kind of 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 each other the setting.
The present invention adopts said structure, has the following advantages: 1, because chamber, the end and fluid-tight chamber are two separate cavitys, the fluid-tight chamber produces bubble for what seal so can avoid air to get into; 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 accompanying drawing and embodiment the present invention is done further detailed explanation;
Fig. 1 is a structural representation of the present invention;
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 water meter character wheel box as shown in Figure 1; 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 each other 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 produces bubble for what seal so can avoid air to get into.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.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
