DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 3 , a smart water meter housing that is easy to disassemble and repair, including a housing body 1, a sensing area 101 is arranged on the housing body, and a meter head locking mechanism 2 is arranged at the lower end of the sensing area 101;

[0021] The meter head locking mechanism 2 includes a locking airbag 201, a pressure regulating sleeve 202 and a pressure regulating piston 203. The locking airbag 201 and the pressure regulating sleeve 202 are fixedly installed at the lower end of the sensing area 101. The pressure regulating piston 203 is inserted into the pressure regulating sleeve 202 and is slidably connected thereto. A pressure regulating tube 204 that passes through the locking airbag 201 is provided at the top of the pressure regulating sleeve 202.

[0022] Furthermore, the locking airbag 201 is an annular structure, a first fixing ring 205 is disposed on the top of the locking airbag 201 , and a second fixing ring 206 is disposed on the bottom of the locking airbag 201 .

[0023] The top and bottom of the locking airbag 201 are fixed by the first fixing ring 205 and the second fixing ring 206. When the air pressure inside the locking airbag 201 increases, the middle part of the locking airbag 201 expands laterally, thereby squeezing the head of the water meter to clamp it. The ring structure improves the effect of fixing the equipment and makes the head of the water meter more centered, thereby improving measurement accuracy.

[0024] Furthermore, the diameter of the second fixing ring 206 is greater than the diameter of the first fixing ring 205 .

[0025] The locking airbag 201 is formed into a conical funnel-shaped structure, which facilitates the installation of the smart meter housing on the meter head of the water meter and avoids interference between the meter head and the second fixing ring 206, thereby affecting the installation efficiency.

[0026] Furthermore, a rotatably connected adjusting screw 207 is provided at the bottom of the pressure regulating piston 203 , and a screw hole is provided at the bottom of the pressure regulating sleeve 202 , through which the adjusting screw 207 is rotatably connected to the pressure regulating sleeve 202 .

[0027] The pressure regulating piston 203 is driven to move by rotating the adjusting screw 207, thereby adjusting the air pressure in the locking airbag 201. Slightly tighten the adjusting bolt to increase the air pressure in the locking airbag 201, and the meter head can be held tightly. When slightly loosen the bolt and the airbag pressure is not enough to hold the meter head tightly, the meter case can be removed.

[0028] Furthermore, a vertical plate 208 is provided at the bottom of the adjusting screw rod 207 .

[0029] The adjusting screw rod 207 can be conveniently and quickly rotated through the vertical plate 208 to adjust the pressure of the locking airbag 201, and the installation and removal of the watch case can be quickly completed without the help of external tools.

[0030] Furthermore, a dust cover 102 rotatably connected via a hinge is provided at the upper end of the sensing area 101 .

[0031] The dust cover 102 prevents dust or rain from falling into the sensing area 101 and affecting the accuracy or service life of the device.

[0032] Furthermore, an inner end surface of the first fixing ring 205 is provided with an internal thread, and the first fixing ring 205 is threadedly connected to the shell body.

[0033] The threaded installation structure allows the locking airbag 201 to be removed when it ages, thereby replacing the locking airbag 201 and improving the convenience of equipment maintenance.

[0034] When the water meter is in use, the smart water meter shell is put on the physical water meter, and the sensing area 101 is aligned with the meter head of the water meter, so that the sensing area 101 is put on the top of the meter head. At this time, the locking airbag 201 wraps the meter head, and the locking bolt is rotated clockwise to drive the pressure regulating piston 203 to move, so as to increase the pressure of the locking airbag 201, so that the locking airbag 201 presses and fixes the meter head. When disassembly is required, the locking bolt is rotated counterclockwise to move the pressure regulating piston 203 downward, so as to lock and release the pressure slightly, and the outer shell body can be quickly removed for inspection and maintenance of its internal components.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
