Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to fig. 1-3, the protection device of intelligent water meter, including last casing 1 and lower casing 2, a plurality of pillars 4 of upper end fixedly connected with of casing 2 down, a plurality of pillar grooves 3 with pillar 4 complex are seted up to the lower extreme of casing 2 down, and pillar 4 sliding connection is in pillar groove 3, the lateral wall of pillar 4 is seted up and is constructed groove 5, sliding connection has two racks 9 in the mechanism groove 5, guide way 10 has been seted up to two relative inner walls in mechanism groove 5, the lateral wall fixedly connected with guide block 6 of rack 9, guide block 6 sliding connection is in guide way 10.

The bottom in the mechanism groove 5 is rotatably connected with a gear 7 which is engaged with the two racks 9, the inner wall of the pillar groove 3 is provided with two limiting holes 16, and the two racks 9 are respectively connected in the two limiting holes 16 in a sliding manner. It should be noted that, referring to fig. 3, the two racks 9 are symmetrically disposed along the axis of the gear 7, so that when the gear 7 rotates, the two racks 9 move toward or away from each other, and enter the removable limiting hole 16. A plurality of operation holes 11 are formed at the lower end of the lower shell 2, and a driving device for driving the rotation of the gear 7 is installed in the operation holes 11.

Drive arrangement is including rotating pivot 8 of connection in operation hole 11, and installs torsional spring 13 on the pivot 8, torsional spring 13's one end and pivot 8 fixed connection, torsional spring 13's other end fixed connection is at the interior top of operation hole 11, and operating hole 11 is installed to 8 spacing stop gear on the pivot. Stop gear includes the dog 14 of sliding connection on the operation hole 11 inner wall, top fixedly connected with gag lever post 17 in the operation hole 11, and gag lever post 17 run through dog 14 and with dog 14 sliding connection. It should be noted that the stopper 14 can be vertically restricted by providing the stopper rod 17 penetrating the stopper 14 so as to be vertically movable only.

The stopper 14 is elastically connected to the inner top of the operation hole 11 through a spring 15, one end of the spring 15 is fixedly connected to the inner top of the operation hole 11, and the other end of the spring 15 is fixedly connected to the side wall of the stopper 14. A limiting plate 12 is fixedly connected to the side wall of the rotating shaft 8.

When the device is used and needs to be disassembled, fingers can be respectively used for stretching into the operation hole 11 and pushing the stop block 14, so that the stop block 14 moves upwards and is no longer limited on the limiting plate 12, the rotating shaft 8 can be pushed to rotate clockwise under the action of the torsion spring 13, the gear 7 is driven to rotate synchronously, and finally the two racks 9 meshed with the gear 7 move oppositely, so that the racks 9 move back into the mechanism groove 5 from the limiting hole 16, the upper shell 1 can be easily lifted at the moment, and the upper shell 1 is separated from the lower shell 2.

When needs are with last casing 1 and casing 2 installation down, earlier go up casing 1 and casing 2 laminating and make pillar 4 get into corresponding pillar groove 3 down, push away again and press dog 14 to the top, then 8 rounds 8 this moment pivots 8 will make gear 7 reversal of anticlockwise rotation pivot, and make two racks 9 leave and can get into spacing hole 16 in, finally make last casing 1, casing 2 combines down, loosen dog 14, spring 15 will promote dog 14 and move down and reset and block limiting plate 12, can fix the position of countershaft 8, gear 7 and rack 9, make last casing 1 link together with casing 2 down.
