The advantage of the invention is that：Guide sleeve is mounted in tooth box, is not influenced meter metering, is not had to dimension after water meter frost
Shield, can automatically reset, solve the problems, such as water meter watch crystal bursting by freezing under microthermal climate.
【Detailed description of the invention】
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of exploded view of Anti-freezing water meter of the present invention.
Fig. 2 is a kind of structural schematic diagram of Anti-freezing water meter (partial sectional view) of the present invention.
【Specific embodiment】
A kind of Anti-freezing water meter 100 referring to FIG. 1-2, including water meter body 10 and a dredging discharging mechanism 20, the water meter body
10 include watchcase 101 and machine core gearcase 102；The dredging discharging mechanism 20 includes bleeder pipe 1, guide sleeve 2, piston 3, spring 4 and pressure
Ring 5；The bleeder pipe 1 is integrally connected on watchcase 101, and is connected with the machine core gearcase 102；Before the guide sleeve 2
The machine core gearcase 102 is protruded at end, and the inside of bleeder pipe 1 is fixed in rear end；The front end of guide sleeve 2 is located at machine core gear after installation
Close to the center of water meter in box 102.The piston 3 can be plugged movably in the guide sleeve 2, and the pressure ring 5 is fixedly connected
In the free end of bleeder pipe 1, the spring 4 is arranged between pressure ring 5 and piston 3.
Referring again to Fig. 1-2, the bleeder pipe 1 includes the small diameter tube 11 and a large-diameter pipe 12 being connected to each other, described small
Diameter pipe 11 is connect with watchcase 101, and the inner wall of the small diameter tube 11 is equipped with the first internal screw thread (not shown)；The outer wall of the guide sleeve 2
Corresponding to being equipped with the first external screw thread (not shown) at the small diameter tube 11, the guide sleeve 2 passes through described first with small diameter tube 11
Internal screw thread, the rotation connection of the first external screw thread.The head of the guide sleeve 2 expands outwardly, and forms a convex shoulder 21, and the convex shoulder 21 is stuck in
The inner end of the large-diameter pipe 12, and one first sealing ring 6 is equipped between the convex shoulder 21 and large-diameter pipe 12.2 tail portion of guide sleeve
Inner wall extend to form a path slot 22 to y direction, the outer diameter of the path slot 22 and the piston 3 matches setting；Institute
The tail end for stating piston 3 is equipped with two grooves 31, and one second sealing ring 7 is arranged on the groove 31.The head of the piston 3 has
There is a bulge loop 32, the bulge loop 32 is stuck on the convex shoulder 21, and the tail end of the spring 4 is stuck on the bulge loop 32.It is described to let out
