Description

Flowmeter reinforcement structure

The invention relates to a flow meter, in particular to a flow meter reinforced structure.

Generally, the structure of the transparent base 11 of the conventional flow meter 1 is as shown in FIG. 1 and FIG. 2 . One side of the transparent base 11 of the flow meter 1 is formed with two opposite plastic connectors 12 and one set. A positioning hole 13 is disposed on one side of the transparent seat body 11. The opposite ends of the positioning plate 13 are respectively provided with a hole 131, and the plurality of plastic sockets 12 on one side of the transparent seat body 11 are respectively provided. The plastic connecting tube 12 is internally provided with a fixing screw hole 121 communicating with the inside of the flow meter 1 to provide a joint 14 to form a screw joint. Each of the joints 14 has a small external thread 141 which is screwed to the fixing screw holes 121 of the plastic connecting tubes 12, and an outer diameter extending toward the ends of the small external threads 141 and an outer diameter larger than the small external threads 141. The large external thread 142 of the diameter, and a locking hole 143 facing the inner side of the large external threads 142 of the joints 14.

In the actual use of the flow meter 1 , please refer to FIG. 3 , the locking holes 143 of the joints 14 in the plastic joints 12 on one side of the transparent seat 11 . In the middle, the external thread segments 151 respectively for the end of one of the pipes 15 are respectively screwed. However, when the field staff has assembled the joints 14 of the plastic nozzles 12 of the flow meter 1 and continue to screw with the pipelines 15, the flowmeter 1 is still incomplete. Where is the details:

Since the transparent base 11 of the flow meter 1 is made of acrylic, the plastic joints 12 on one side of the transparent base 11 are opposite to the inner side of the large external threads 142 of the joints 14 .
