Description

Unidirectional cover gauge head structure

Technical field

This utility model relates to flow monitoring device technical field, and specifically, being that one is unidirectional covers gauge head structure。

Background technology

Water meter, as flow detector, is widely used；Along with the development of city size, water meter make consumption also increasing, for solving problems of management such as monitoring, check meter, the intellectual water meter with the function such as monitoring position, remote meter reading just arises at the historic moment；Existing Water meter header structure is that watchcase lower end is covered with bottom mostly, and for convenience of installation and removal, bottom can take off outside gauge outfit, but the water meter of this structure, be applied in outdoor or unserviced local time, frequent appearance artificially sabotages phenomenon；And in the processes such as water meter handling process, water meter bottom also easily comes off。

Utility model content

In view of this; this utility model offer one is unidirectional covers gauge head structure; watchcase and bottom are provided with the clamp being mutually matched and chuck; after making clamp be stuck in chuck bottom water meter; just cannot take off bottom outside watchcase again; protection water meter internal structure, is also prevented from the processes such as carrying, and bottom holds caducous phenomenon。

Concrete technical scheme is as follows:

One is unidirectional covers gauge head structure, and including watchcase, described watchcase front-rear side walls is arranged below flow transducer mounting groove, and the bottom of described watchcase is covered with bottom；It it is critical only that: is provided with chuck on described watchcase medial wall, and described chuck is positioned at described watchcase lower end；Being provided with corresponding clamp on described bottom lateral wall, described clamp is positioned at described bottom sidewall upper；Described clamp flexible clamping is in described chuck。

Based on the design of said structure, in covering process, the clamp angular rim on described bottom is against on the angular rim of described chuck, and owing to chuck maintains static, clamp relies on himself elasticity inwardly to deform upon, until clamp is stuck in chuck, clamp resiles。At this moment, owing to clamp is stuck in chuck in inside, it is impossible to open described bottom from the bottom of described watchcase, it is prevented that water meter is opened by artificial deliberating。

Further, in order to realize chuck and clamp unidirectional button and, described chuck is right angled triangle, and upward, long right-angle side overlaps with the medial wall of described watchcase at its right angle；Described clamp is right angled triangle, and down, long right-angle side overlaps with the lateral wall of described bottom at its right angle；During abutting, the angular rim of clamp is connected on the angular rim of chuck, and moves up, until the right-angle side of clamp overlaps with the right-angle side of chuck；At this moment, bottom is spacing by the limited step of watchcase on the one hand, is stuck in described chuck by clamp on the other hand, it is impossible to take off described bottom outside gauge outfit；Unless inside watchcase, artificially applied inwardly to occur elastically-deformable power to clamp。

In the specific implementation, described chuck and described watchcase are formed in one structure；Described clamp and described bottom are formed in one structure。Described chuck and clamp are provided with two groups, are symmetrically distributed in gauge outfit centrage both sides。

Beneficial effect: non-technical personnel from watchcase external opening bottom, cannot protect water meter internal structure；Prevent bottom in the processes such as carrying easy to fall off。

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail。

One as Figure 1-4 is unidirectional covers gauge head structure, and including watchcase 1, described watchcase 1 front-rear side walls is arranged below flow transducer mounting groove 3, and the bottom of described watchcase 1 is covered with bottom 2；It it is critical only that: is provided with chuck 11 on described watchcase 1 medial wall, and described chuck 11 is positioned at described watchcase 1 lower end；Being provided with corresponding clamp 21 on described bottom 2 lateral wall, described clamp 21 is positioned at described bottom 2 sidewall upper；Described clamp 21 flexible clamping is in described chuck 11。

Based on the design of said structure, in covering process, clamp 21 angular rim on described bottom 2 is against on the angular rim of described chuck 11, owing to chuck 11 maintains static, clamp 11 relies on himself elasticity inwardly to deform upon, until clamp 21 is stuck in chuck 11, clamp 21 resiles。At this moment, owing to clamp 21 is stuck in chuck 11 in inside, it is impossible to open described bottom 2 from the bottom of described watchcase 1, it is prevented that water meter is opened by artificial deliberating。

As shown in Figure 3 and Figure 4, in order to realize chuck 11 and clamp 21 unidirectional button and, described chuck 11 is right angled triangle, and upward, long right-angle side overlaps with the medial wall of described watchcase 1 at its right angle；Described clamp 21 is right angled triangle, and down, long right-angle side overlaps with the lateral wall of described bottom 2 at its right angle；During abutting, the angular rim of clamp 21 is connected on the angular rim of chuck 11, and moves up, until the right-angle side of clamp 21 overlaps with the right-angle side of chuck 11；At this moment, as can be seen from Figure 2, bottom 2 one aspect is spacing by the limited step of watchcase 1, is stuck in described chuck 11 by clamp 21 on the other hand, it is impossible to take off described bottom 2 outside gauge outfit；Unless inside watchcase 1, artificially to clamp 21 to apply inwardly elastically-deformable power to occur。

In the present embodiment, the structure as it is shown in figure 1, described chuck 11 and described watchcase 1 are formed in one；Described clamp 21 and described bottom 2 are formed in one structure。Described chuck 11 and clamp 21 are provided with two groups, are symmetrically distributed in gauge outfit centrage both sides。

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model。
