[0027] Furthermore, the quick docking mechanism includes an insert block 6 fixedly connected to the protective cover 3 and a clamping seat 7 fixedly connected to the protective base 2. The insert block 6 is movably inserted into the inside of the clamping seat 7. The overall structure of the quick docking mechanism is simple, and the protective base 2 and the protective cover 3 are quickly clamped and positioned by utilizing the clamping connection between the insert block 6 and the clamping seat 7.

When the latch 701 is inserted into the locking hole 601 to lock the position of the plug block 6, the spring 703 applies elastic force to the slider 702 and the latch 701, so that the latch 701 is stably inserted and not easy to loosen or come off.

[0029] Furthermore, a screw rod 501 is threadedly connected to the protective cover 3, and the cable clamping cover 5 is rotatably connected to the screw rod 501.

When the cable clamping cover 5 moves, the lateral support rod 502 is synchronously driven to slide along the protective cover 3, and the lateral support rod 502 provides support and limitation for the cable clamping cover 5.

[0030] A rotating handle 503 is fixedly connected to the screw rod 501 , and the rotating handle 503 makes the screw rod 501 easy to rotate and saves effort.

[0031] A flange 102 is fixedly connected to the flow meter body 1 , and the arrangement of the flange 102 facilitates the installation of the flow meter body 1 .

[0032] The turbine flowmeter for water metering can provide protection for the flowmeter body 1 through the design of the protective base 2 and the protective cover 3, so as to avoid the flowmeter body 1 from being damaged by collision and ensure good stability during the water metering process.

After the complete insertion, release the slider 702, the spring 703 resets and pushes the slider 702 and the latch 701 to move, so that the latch 701 is inserted into the lock hole 601, thereby realizing the loading and fixing of the protective base 2 and the protective cover 3;

[0034] After the protective base 2 and the protective cover 3 are fixed, the rotating screw rod 501 can push the cable clamping cover 5 to move, and cooperate with the cable clamping seat 4 to realize the clamping of the cable 101, thereby ensuring the stable clamping of the cable 101.
