Description

Technical Field

[0001] This utility model relates to a pressure resistance testing device for plastic water meter housings. Background Technology

[0002] Plastic water meter casings are widely used, offering advantages such as lightweight, environmental friendliness, and resistance to scale buildup. During production, the pressure resistance of finished water meter casings typically needs to be tested to ensure quality. However, current pressure testing methods require the casing to be face-up for frontal pressure testing, followed by rotation by the operator to face side-up for side pressure testing. This process is cumbersome and inconvenient. Therefore, developing a pressure testing device for plastic water meter casings is essential to address these issues. Utility Model Content

[0018] See Figures 1 to 5The device shown is a pressure resistance testing device for plastic water meter housings, including an operating table 11, an L-shaped plate 12 on the operating table 11, a hydraulic cylinder 13 on the L-shaped plate 12, a pressure plate 14 at the bottom of the hydraulic cylinder 13, a pad 15 and a pad 16 on the operating table 11, a motor 17 on the pad 15, a clamping assembly 18 on the output shaft of the motor 17, a mounting assembly 19 on the pad 16, a lifting plate 22 between the pad 15 and the pad 16, a control cavity 20 on the operating table 11, the lifting plate 22 penetrating the top wall of the control cavity 20, a plurality of hydraulic rods 21 between the lifting plate 22 and the bottom wall of the control cavity 20, and a mounting plate 23 on the lifting plate 22.

[0019] Furthermore, the clamping assembly 18 includes a clamping box 24, which is connected to the output shaft of the motor 17. Two sliding plates 25 are slidably arranged inside the clamping box 24. A clamping plate 26 is provided on one side of the sliding plate 25, and a connecting rod 27 is provided on the other side of the sliding plate 25. A spring is provided on the connecting rod 27. One end of the connecting rod 27 passes through the side wall of the clamping box 24, and a pull plate 28 is provided at the end of the connecting rod 27.

[0020] Furthermore, the clamping plate 26 is made of polyurethane rubber; the polyurethane rubber clamping plate 26 is relatively soft, and when the two clamping plates 26 clamp the water pipe port of the plastic water meter shell, it can prevent the clamping plate 26 from being too hard and damaging the plastic water meter shell.

[0021] Furthermore, the mounting component 19 includes an arc plate 29 and a column 30, the column 30 being fixed on the pad 16, and the arc plate 29 being fixed on the top of the column 30.

[0022] Furthermore, a plurality of angle irons 31 are provided between the lifting plate 22 and the mounting plate 23. One side of the angle iron 31 is fixed to the lifting plate 22, and the other side of the angle iron 31 is connected to the mounting plate 23 by bolts. When the mounting plate 23 is damaged due to long-term pressure, the mounting plate 23 can be removed from the lifting plate 22 and replaced by unscrewing the bolts between the angle iron 31 and the mounting plate 23.

[0023] The working principle of this utility model is as follows: When performing a pressure resistance test on a plastic water meter casing, the plastic water meter casing is first placed on the mounting plate 23 with its front side facing up. One water supply pipe port of the water meter casing is placed on the mounting component 19. Then, the pull plate 28 is pulled, causing the sliding plate 25 and the clamping plate 26 to move accordingly, thereby separating the two clamping plates 26 from each other. Then, the other water supply pipe port of the water meter casing is inserted between the two clamping plates 26. The pull plate 28 is released, causing the two clamping plates 26 to clamp the water supply pipe port of the water meter casing under the action of the spring. After that, the hydraulic cylinder 13 is activated to lower the pressure plate 14. The pressure plate 14 presses down on the water meter casing and applies pressure to it, thereby performing a front pressure resistance test on the water meter casing.

[0024] After the front pressure resistance test is completed, the hydraulic cylinder 13 retracts to reset the pressure plate 14, and the hydraulic rod 21 retracts to lower the lifting plate 22, so that the placement plate 23 maintains a certain distance from the water meter housing placed between the clamping assembly 18 and the placement assembly 19, so as not to hinder the subsequent rotation of the water meter housing. Then, the motor 17 is started to rotate the clamping box 24 ninety degrees, so that the side of the water meter housing faces upward. Then, the hydraulic rod 21 is started to extend to raise the lifting plate 22, so that the placement plate 23 is placed on the bottom of the water meter housing. After that, the hydraulic cylinder 13 is started to extend to lower the pressure plate 14, which presses down on the water meter housing and applies pressure to it, thereby performing a side pressure resistance test on the water meter housing.

[0025] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
