Take, illegally water meter realizing self disassembling is removed, water meter is caused to cannot achieve function of measuring, to bring economic damage to water supply department
It loses.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, easy for installation, water of effective tamper
Table apparatus preventing water robbing.
To realize above-mentioned technical problem, the solution that the utility model is taken is：A kind of apparatus for water meter of preventing fraudulent use of water, including
Upper annulus and lower annulus opposite can constitute annulus between upper annulus and lower annulus, and the annulus can be set in water meter and pipe
The joint in road further includes lock-screw and anti-theft ring；Locking slot, the lock are offered on the locking end of the lock-screw
It is convexly equipped with antitheft column in tight slot, antitheft card slot is distributed on the circumferential surface of the antitheft column, the side channel wall of the locking slot is in
Inner conical surface is located at the position below inner conical surface on the side channel of locking slot and is equipped with internal thread；Described its circle spacing of anti-theft ring upper edge
Formula is equipped with multiple elastic claws, and multiple antitheft latches, the free end of the elastic claw is distributed on the elastic claw madial wall
Lateral wall be male cone (strobilus masculinus), the straight slot worn for the antitheft column is constituted between each elastic claw madial wall；The upper annulus is equipped with
For the installation perforation that the lock-screw is worn, the position that the lower annulus corresponds to the installation perforation offers mounting groove, institute
It states and is convexly equipped with threaded post in mounting groove, offered in threaded post and supply the fixed embedded groove of anti-theft ring insertion, outside threaded post
Side wall is equipped with external screw thread；The lock-screw is penetrated by installation in mounting groove, the internal thread and threaded post of lock-screw
External screw thread be threadedly coupled, the antitheft column of lock-screw is through in anti-theft ring, and the Anti-theft card tooth engagement of elastic claw is in antitheft column
In antitheft card slot.
Further, being additionally provided with elastic seal ring between the anti-theft ring and the slot bottom of embedded groove；Elastic seal ring pair
Anti-theft ring has elastic shock attenuation cushioning effect, avoids the accidental damage phenomenon of anti-theft ring in transport installation process.
By using preceding solution, the utility model has the beneficial effects that：The water meter safety water designed as described above
Device when installation, constitutes annulus by upper annulus and lower annulus are opposite in the joint of water meter and pipeline, then leads to lock-screw
The installation for crossing annulus penetrates in the mounting groove of lower annulus, at this point, elastic claw is in open state, locking screw in anti-theft ring
The antitheft column of nail unimpeded can be penetrated in anti-theft ring, lock-screw then be rotated, with the internal thread and screw thread of lock-screw
The externally threaded screw thread rotation of column connects, and lock-screw is gradually locked, the inner conical surface of the locking slot of lock-screw also gradually with it is anti-
Matching pushing occurs for the male cone (strobilus masculinus) for stealing the elastic claw of ring so that elastic claw collapses gradually, when the elastic claw of anti-theft ring collapses completely
When fitting is with antitheft column, each antitheft latch can be engaged in each antitheft card slot, the engagement of antitheft latch and antitheft card slot
So that lock-screw can not rotate, the opposite installation of upper annulus and lower annulus is fixed to be completed；And if someone will force to lock
Tight screw carries out continuing rotation dismounting, can once be found by shakedown, management company between antitheft latch and antitheft card slot
The structure is destroyed, then can determine whether that water meter was artificially dismantled；Therefore, the apparatus for water meter of preventing fraudulent use of water be installed on water meter and
The joint of pipeline has effective tamper effect, and then water meter is avoided to be removed once installation can not be removed without destroying, and rises
It is acted on to water meter safety water, and simple in structure, simple installation, practicability is high.
