Abstract
The utility model discloses a waterproof mounting structure of water gauge, including watchcase and flow sensor, its key lies in: be provided with the spacing groove under the watchcase on the terminal surface, limiting groove has placed the sealing washer, flow sensor is last be provided with with the corresponding spacing arch of spacing groove, during the installation, spacing arch stretches into the limiting groove butt is in on the sealing washer, the spacing groove with still set up corresponding screw in the spacing arch to through screw fixed connection the watchcase with flow sensor. Beneficial effect: use the sealing washer effectively with in the watchcase with flow buret and keep apart, it rusts to prevent that metal element such as watchcase internal electric circuit board and screw from weing.
Description
Technical field
The utility model relates to flow monitoring device technical field, specifically, is the waterproof assembling structure of a kind of water meter.
Background technology
Water meter, as flow detector, is widely used; Along with the development of city size, the usage quantity of water meter is also increasing, for solving handling problem such as monitoring, check meter, just arises at the historic moment with the intellectual water meter of the function such as monitoring position, remote meter reading; The waterproof assembling structure of existing water meter is mounted with control circuit board mostly in watchcase, it is necessary to building dry environment in watchcase. But existing Water meter header structure, mostly on watchcase and flowtube, it is provided with corresponding screw, with this, flowtube is fixed on watchcase, this kind of mode simply and saves watchcase space, but screw place poor sealing, often makes the globule of condensation on flow tube wall enter in watchcase, causes circuit card to make moist and get rusty, affect circuit card normal operation, and then affect water meter normal operation; And coupling screw is more in watchcase, being in wet environment for a long time, screw makes moist and gets rusty so that water meter housing is not easily opened, and affects technician and keeps in repair water meter etc.
Practical novel content
In view of this, the utility model provides the waterproof assembling structure of a kind of water meter, and by adding sealing-ring at watchcase and flowtube junction, stopping steam, to enter watchcase chamber indoor, prevents the elements such as circuit card from getting rusty damage.
Concrete technical scheme is as follows:
The waterproof assembling structure of a kind of water meter, comprise watchcase and flow sensor, its key is: be provided with spacing groove on described watchcase lower surface, it is placed with sealing-ring in described spacing groove, described flow sensor is provided with the spacing preiection corresponding with described spacing groove, during installation, described spacing preiection stretches in described spacing groove and is connected on described sealing-ring; Described spacing groove and described spacing preiection also offer corresponding screw, and is fixedly connected with described watchcase and described flow sensor through screw.
Based on the design of said structure, described sealing-ring prevents on flow tube wall the globule of condensation to enter in described watchcase, effectively prevents the metal elements such as the control circuit board of described watchcase and screw from making moist and gets rusty, ensures the normal operation of water meter.
Further, the watchcase upper surface at described spacing groove place being also provided with screw and installs groove, the ailhead of described screw is embedded in described screw and installs in groove, effectively saves space in watchcase.
Further, described watchcase is also provided with signal wire through hole, for drawing transducer signal outlet line, and the extraction in described signal wire through hole after gasket of transducer signal outlet line, described gasket is connected to below described signal wire through hole hole wall, it is achieved seal further.
In the specific implementation, the connection structure that described spacing groove and described spacing preiection are formed comprises four, the rectangular medullary ray both sides being distributed in described watchcase.
Useful effect: use sealing-ring effectively to get up in watchcase with flowtube isolation, prevent the metal elements such as watchcase interior circuit board and screw from making moist and get rusty.
Accompanying drawing explanation
Fig. 1 is structure iron of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
The waterproof assembling structure of a kind of water meter as shown in Figure 1 to Figure 3, comprise watchcase 1 and flow sensor 2, its key is: as can be seen from Figure 3, described watchcase 1 lower surface is provided with spacing groove 3, it is placed with sealing-ring 4 in described spacing groove 3, being provided with the spacing preiection 5 corresponding with described spacing groove 3 on described flow sensor 2, during installation, described spacing preiection 5 stretches into and is connected on described sealing-ring 4 in described spacing groove 3; Described spacing groove 3 and described spacing preiection 5 also offer corresponding screw, and is fixedly connected with described watchcase 1 and described flow sensor 2 through screw 6.
Based on the design of said structure, described sealing-ring 4 prevents on flow tube wall the globule of condensation to enter in described watchcase 1, effectively prevents the metal elements such as the control circuit board of described watchcase 1 and screw from making moist and gets rusty, ensures the normal operation of water meter.
By Fig. 1 can Fig. 3 also it can be seen that watchcase 1 upper surface at described spacing groove 2 place is also provided with screw install groove 7, the ailhead of described screw 6 is embedded in described screw and installs in groove 7, effectively saves space in watchcase 1.
As depicted in figs. 1 and 2, described watchcase 1 is also provided with signal wire through hole 8, for drawing transducer signal outlet line, and transducer signal outlet line draws in described signal wire through hole 8 through after gasket 9, described gasket 9 is connected to below described signal wire through hole 8 hole wall, it is achieved seal further.
In the present embodiment, as shown in Figure 1, the connection structure that described spacing groove 3 and described spacing preiection 5 are formed comprises four, the rectangular medullary ray both sides being distributed in described watchcase 1.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all any amendment, equivalent replacement and improvement etc. done within spirit of the present utility model and principle, all should be included within protection domain of the present utility model.
