Abstract

The utility model discloses an intelligent water meter dismounting-prevention device which is formed by the involution of two semi-box bodies; wherein, one grab is arranged on one semi-box body, and a blocking groove matched with the grab is arranged on the other semi-box body. The clamping surface of the grab is vertical to the side wall of the box body. The dismounting-prevention device is arranged on the outer side of the joint of the water meter and a water pipe, before dismounting the water meter, the water meter is firstly broken, thereby preventing from dismounting the water meter at will and achieving the purpose of preventing water theft.

Description

The intellectual water meter anti-disassembling device

Technical field

The utility model relates to a kind of water meter spare and accessory parts, refers to a kind of intellectual water meter anti-disassembling device especially.

Background technology

Urban water supply all is to measure with water meter, and water meter provides the foundation of charge for Running-water Company.Present most of water meter is a pointer gauge, judges water consumption by the pointer data on the water-meter reading.This mode needs Running-water Company to send the special messenger regularly to check meter to the doorstep, and then pays water rate by the user, not only wastes time and energy, and also wastes a lot of manpowers, and it is very inconvenient that the user also feels, a kind of intellectual water meter occurred for this reason.This intellectual water meter is that the mode by plug-in card obtains water, and the user buys the IC-card (or other card type) of having supplemented with money in advance, is inserted in then on the slot of water meter, by the control of the circuit structure in water meter water outlet.After the amount of money in the IC-card used up, the user can buy neocaine once more, or the former row that sticks into is supplemented with money.This intellectual water meter does not need Running-water Company regularly to check meter to the doorstep, has saved a lot of manpower and materials, and is very convenient concerning the user yet.

Though intellectual water meter is easy to use,, also just brought the stolen water problem because Running-water Company need not call for a long time.Some immoral user directly dismantles water meter, water meter is loaded onto when having the people to check to the doorstep by the time, and this intellectual water meter can't judge whether people's stolen water again, and Running-water Company does not just have the evidence proof that people's stolen water is arranged yet.

At the problems referred to above, the design people concentrates on studies, and has this case to produce finally.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of random intellectual water meter anti-disassembling device that water meter is dismantled that prevents.

For solving the problems of the technologies described above, technical solution of the present utility model is:

A kind of intellectual water meter anti-disassembling device, it is involuted by the two halves box body, and wherein half box body is provided with grab, and second half box body is provided with the draw-in groove that cooperates with grab.

Described two halves box body is identical structure, is provided with relative grab in position and draw-in groove on per half box body.

The snap-latch surface of described grab is perpendicular to the sidewall of box body; Described draw-in groove then is arranged on the interior radially dividing plate of box body.

Described draw-in groove extends to the outside of box body, and the draw-in groove next door has perforate, and one strengthens button is buckled in this draw-in groove and the perforate outside, and this reinforcement button is provided with the coupler body that can engage with perforate or grab.

After adopting such scheme, utilize anti-disassembling device described in the utility model, the joint capping of water meter and water pipe can be got up,, so just can prevent from arbitrarily to dismantle water meter, reach the purpose of anti-stolen water if the dismounting water meter must destroy this device earlier.In other words, if anti-disassembling device described in the utility model is destroyed, just can tentatively judge has the people to tear water meter steathily open, can reach the effect of caution.

Fig. 2 is an assembled sectional view of the present utility model;

Fig. 3 is the left view of Fig. 2;

Fig. 4 is the schematic perspective view that is installed in the watermeter connector place of the present utility model;

Fig. 5 is the assembled sectional view that is installed in the watermeter connector place of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

What the utility model disclosed is a kind of intellectual water meter anti-disassembling device, as Fig. 1,2 and shown in Figure 3, is preferred embodiment of the present utility model.Described anti-disassembling device is involuted by the two halves box body, and wherein half box body is provided with grab 11, and second half box body is provided with the draw-in groove 12 that cooperates with grab 11.

During use, the two halves box body of described anti-disassembling device is buckled in outside the joint 5 of water meter 3 and water pipe 4, and engages mutually with draw-in groove 12, can prevent that like this people from disassembling water meter 3, if rigid dismounting then will certainly destroy this device with grab 11.

And in order to reduce number of molds, reduce cost, described two halves box body can be arranged to identical structure.Shown in embodiment among the figure, on per half box body 1, be provided with two relative grabs 11 of position and draw-in groove 12.During fastening, wherein the grab 11 of half box body 1 engages with the draw-in groove 12 of second

half box body

1, and 11 of the grabs of second half box body 1 engage with the draw-in groove 12 of the first half box body 1.

In addition, the snap-latch surface of described grab 11 can be perpendicular to the sidewall of box body 1, and the reason of She Zhiing is like this: if the snap-latch surface of grab is parallel to box side wall, push box side wall, might make the engaging of grab disengaging draw-in groove and the two halves box body is separated.And in order to cooperate vertically disposed grab 11, described draw-in groove 12 can be arranged on the radially dividing plate 13 in the box body 1.Die sinking for convenience simultaneously, this draw-in groove 12 extends to the outside of box body 1 usually, and this structure can make grab 11 expose, if stretch in the draw-in groove 12 by instrument, just might make grab 11 separate with draw-in groove 12, thereby reduces anti-theft effect., can strengthen button 2 with one then and be buckled in the described draw-in groove 12 and perforate 14 outsides in draw-in groove 12 next door perforates 14, this reinforcement button 2 is provided with the coupler body 21 that can engage with perforate 14 or grab 11 for this reason.Strengthening button 2 can be with described draw-in groove 12 and perforate 14 capping, thereby prevent that described grab 11 from exposing, and in case this reinforcements button 2 be stuck in perforate 14 edges with its coupler body 21 or be stuck on the grab 11 (present embodiment be the coupler body 21 that will strengthen button 2 block on the grabs 11) and be placed on after draw-in groove 12 outsides, do not destroy reinforcement button 2 and just be difficult to it is unloaded from box body 1, thereby can reach better anti-theft effect.
