Abstract
The invention relates to a dual-rubber-ring sealed waterproof structure of a wet-type water meter and aims at providing the dual-rubber-ring sealed waterproof structure of the wet-type water meter which has the advantages that liquid or gas which is filled into a number wheel case of the water meter does not leak, liquid or gas outside the number wheel case does not enter the number wheel case, the reliability and the efficiency are high and the technological operation is simple. The dual-rubber-ring sealed waterproof structure of the wet-type water meter comprises a water meter number wheel set. The water meter number wheel set is arranged in the number wheel case of the water meter. The water meter number wheel set comprises a number wheel shaft. The number wheel shaft penetrates through the inside and the outside of the number wheel case. A conical rubber ring is arranged between the number wheel shaft and the number wheel case. An O-shaped rubber ring is arranged between the number wheel shaft and the number wheel case. An O-shaped ring cover is arranged outside the O-shaped rubber ring. A cross toothed wheel is arranged on the number wheel shaft. The dual-rubber-ring sealed waterproof structure of the wet-type water meter has the advantages of good sliding performance and excellent sealing effect, and is suitable for the wet-type water meters.
Description
Technical field
The present invention relates to a kind of water meter, more specifically say, relate to a kind of two rubber sealing waterproof constructions of wet-type meter.
Background technology
In the prior art; Water meter manufacturer is for after solving the long-time use of small-bore wet type vane wheel water meter counter dial; Occur jaundice, blackening easily, be prone to the defective that tongue green for a long time influences reading, the character wheel group in the water meter counter is placed the character wheel box, around the character wheel box and bottom and tested current separate; Only on the character wheel box, have 4 or 5 character wheel windows supplying reading, avoid the defective that character wheel is stuck by some impurity in the water or the appearance influence is checked meter.In order to guarantee that meter reading keeps clear always, producer pours into liquid or gases such as pure water or glycerine in the character wheel box.But because of print wheel shaft passes the reason that always there is the space character wheel box position, liquid in the character wheel box or gas can exchange with character wheel box outside liquid or gas in long-term use, form seepage, accumulate over a long period, and have influence on the normal use of water meter.There is the technological deficiency of easy seepage in the character wheel box of water meter in the prior art, becomes those skilled in the art's technical matters anxious to be solved.
Summary of the invention
There is the technical matters of easy seepage in the character wheel box that the objective of the invention is to solve water meter; Provide a kind of liquid or gas of the inner embedding of character wheel box of water meter can not leak; Character wheel box outside liquid or gas can not enter in the character wheel box yet, two rubber sealing waterproof constructions of reliable and effective, the simple wet-type meter of technological operation.
For realizing above technical purpose, technical scheme of the present invention is:
A kind of two rubber sealing waterproof constructions of wet-type meter include water meter character wheel group, and said water meter character wheel is mounted in the water meter character wheel box; It is characterized in that: said water meter character wheel group includes print wheel shaft; Said print wheel shaft penetrates inside and outside the character wheel box; Be provided with the cone rubber circle between said print wheel shaft and the character wheel box; Be provided with O shape rubber ring between said print wheel shaft and the character wheel box, said O shape rubber ring is provided with O type circle cover outward, and said print wheel shaft is provided with the cross gear wheel.
Further, said cone rubber circle inboard is provided with projection, and said print wheel shaft is provided with and the inboard projection corresponding groove of cone rubber circle.
Further, said print wheel shaft is provided with and O shape rubber ring corresponding groove.
Further, said O shape rubber ring and cone rubber circle are the magnetic rubber material.
Further, said O shape rubber ring and cone rubber circle are the nitrile rubber material.
Further, said O shape rubber ring and cone rubber circle are silastic material.
The double-deck rubber sealing waterproof construction of cone rubber circle and O shape rubber ring, owing on print wheel shaft, be provided with groove, sliding is good, sealing effectiveness is good.O shape rubber ring and cone rubber circle are that the magnetic rubber material has more strengthened beyond thought sealing effectiveness.Liquid or gas in the character wheel group no longer leak, and character wheel box outside liquid or gas can not infiltrate in the character wheel box, have prolonged the serviceable life of water meter.
Description of drawings
Fig. 1 is the cross-sectional view of one embodiment of the invention.
Fig. 2 is the print wheel shaft synoptic diagram of one embodiment of the invention.
Embodiment
In conjunction with accompanying drawing, specify embodiment of the present invention, but claim is not done any qualification.
In Fig. 1, Fig. 2, include water meter character wheel group 7 in two rubber sealing waterproof constructions of a kind of wet-type meter of the present invention, said water meter character wheel group 7 is located in the water meter character wheel box 6; Said water meter character wheel group 7 includes print wheel shaft 2; Said print wheel shaft 2 penetrates inside and outside character wheel box 6; Be provided with cone rubber circle 5 between said print wheel shaft 2 and the character wheel box 6; Be provided with O shape rubber ring 4 between said print wheel shaft 2 and the character wheel box 6, said O shape rubber ring is provided with O type circle cover 3 outward, and an end of print wheel shaft is provided with cross gear wheel 1.Said cone rubber circle 5 inboards are provided with projection, and said print wheel shaft is provided with and cone rubber circle 5 inboard projection corresponding groove.In force, print wheel shaft 2 is provided with and O shape rubber ring 4 corresponding groove.O shape rubber ring and cone rubber circle adopt the magnetic rubber manufacture of materials, have more strengthened beyond thought sealing effectiveness.In force, O shape rubber ring and cone rubber circle are the nitrile rubber material.O shape rubber ring and cone rubber circle also can adopt silastic material.
Sliding of the present invention is good, and sealing effectiveness is good, has prolonged the serviceable life of water meter.It is the original creation invention in this area.
