[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example

[0021] Please see Figures 1-4 A novel pressure-resistant housing for an ultrasonic heat meter includes a pipe 1, a first housing 2 and a second housing 3 respectively provided on the front and rear sides of the pipe 1, and an arc-shaped slot matching the diameter of the pipe 1 is opened on the inner side of the first housing 2 and the second housing 3. A top cover 4 is rotatably connected to the upper side of the first opening, and a glass plate 5 is embedded in the middle part of the top cover 4.

[0022] Guide rods 6 are provided on both sides of the upper side of the top cover 4. Scrapers 7 are slidably connected to the guide rods 6. Connecting components are provided on both sides of the first housing 2 and the second housing 3. Insertion block 8 is provided on the lower side of the top cover 4. Slot 9 corresponding to insertion block 8 is provided on the upper side of the second housing 3.

[0023] The connecting assembly includes a first groove 10 and a second groove 11 respectively opened on one side of the first housing 2 and the second housing 3. A strip 12 is rotatably connected inside the first groove 10, and a connecting block 13 is provided on one side of the strip 12. A connecting groove 14 corresponding to the connecting block 13 is opened inside the second groove 11.

[0024] It should be noted that after the ultrasonic heat meter is installed on the pipe 1, the operator can cover the outside of the pipe 1 with the first housing 2 and the second housing 3. At this time, the first housing 2 and the second housing 3 will cover the ultrasonic heat meter located on the pipe 1. Then, the operator rotates the strip 12 inside the first groove 10 and inserts the connecting block 13 into the connecting groove 14. Then, the bolt passes through the second through hole and is threaded into the second threaded hole. Then, with the strip 12, the connection between the first housing 2 and the second housing 3 can be completed. Then, the operator can rotate the top cover 4 and insert the insert 8 on the lower side of the top cover 4 into the corresponding slot 9. The bolt passes through the first through hole and is threaded into the first threaded hole, thereby completing the connection between the top cover 4 and the second housing 3. Finally, a stable connection between the first housing 2, the second housing 3 and the top cover 4 is completed. When the ultrasonic heat meter is running, it can protect it and prevent external pressure impact from damaging the ultrasonic heat meter.

[0025] Meanwhile, a glass plate 5 is embedded on the upper side of the top cover 4. When the ultrasonic heat meter is running, the operator can read the value on the ultrasonic heat meter through the glass plate 5. As the usage time goes by, the glass plate 5 is prone to symmetrical accumulation. At this time, the operator can use the moving handle 15 to slide the scraper 7 along the guide rod 6 to clean the surface of the glass plate 5, which makes it easier to read the value vertically of the transformer ultrasonic heat meter.

[0026] Meanwhile, the operator can remove the bolts at the first through hole and the first threaded hole, and lift the top cover 4. Then, simple maintenance operations can be performed on the ultrasonic heat meter. In this technical solution, only the first housing 2 and the second housing 3 are used as the main body. The overall structure is simple, and the connection between the two is convenient and tight. When the ultrasonic heat meter is subjected to external pressure or impact, the ultrasonic heat meter can be effectively protected.

[0027] A sealing strip 16 is provided on the inner side of the arc-shaped groove to increase the sealing between the first housing 2, the second housing 3 and the pipe 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
