Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, in particular to a device for detecting the pressure resistance of a water meter shell during production. Background Art

[0002] The water meter housing provides physical protection for the internal components of the water meter, preventing the influence of water flow, dust, corrosion and other external factors. The water meter housing usually has good waterproof performance, ensuring that the internal electronic components can work normally even in humid or water-flowing environments. The water meter housing is usually made of corrosion-resistant materials to resist the chemical components and corrosive substances in the water, thereby extending the service life of the water meter.

[0003] The principles behind testing the compressive performance of water meter housings during production primarily involve mechanical principles and sensor technology. The device applies axial pressure to test the compressive strength of the meter housing, typically using a hydraulic or mechanical system to provide uniform pressure. The device then tests the housing's deformation and damage under specific pressure. The device is typically equipped with a pressure sensor to monitor the pressure applied to the meter housing in real time, ensuring the accuracy and reliability of the test.

[0004] In the existing pressure resistance performance test of water meter housing, most of the water meter housings are placed on a test platform and a driving device is used to perform pressure test on the water meter housing. Such pressure resistance test will cause displacement or deformation during the test due to lack of fixation. This displacement will affect the actual pressure applied to the housing, resulting in inaccurate test results, and thus unable to truly reflect the pressure resistance of the water meter housing. Therefore, to address the above problems, a water meter housing production pressure resistance performance testing device is proposed. Utility Model Content

When the gear 11 rotates, it drives multiple limiting rods 16 provided inside to rotate. The rotation of the multiple limiting rods 16 drives the connecting ring 12 provided at the bottom to rotate. The rotation of the connecting ring 12 drives the connecting rod 13 to rotate. The rotation of the connecting rod 13 drives the clamp 14 to clamp and fix the water meter shell. Then, the cylinder 2 is started. 0 drives the fixed plate 21 to move, and the movement of the fixed plate 21 drives the pressure detector 22 and the pressure detection head 23 provided below to move.
