Description

Technical Field

[0001] This utility model relates to the field of fluid metering equipment testing technology, and in particular to a fixing fixture for testing the sealing performance of IC card water meters. Background Technology

[0002] As a crucial component of modern intelligent water management systems, the quality of IC card water meters directly impacts the accuracy of metering and the reliability of water supply. Before leaving the factory, IC card water meters must undergo rigorous quality testing, with sealing performance testing being a critical step. This test typically requires applying high water pressure inside the meter to check for leaks in its casing and connections under pressure.

[0003] When conducting such sealing tests, it is usually necessary to connect the IC card water meter to the pressurized pipeline. However, during the pressurization process, the water meter body and the connecting pipeline will be subject to internal pressure, causing them to shake or shift. This instability not only affects the accuracy of the test data but can also lead to loose connections and misjudgments of leaks. Existing operating methods often simply involve placing the water meter on the test bench, lacking stable and reliable fixing measures.

[0004] More seriously, the sealing test itself carries inherent safety risks. If the IC card water meter has manufacturing defects or insufficient material strength, it may suddenly rupture or burst under high pressure, causing the high-pressure water inside to spray out violently, posing a serious threat to the personal safety of surrounding test personnel. Current testing environments generally lack effective safety protection devices for such emergencies, resulting in severely inadequate safety guarantees for operators.

[0005] Therefore, existing technologies for testing the sealing performance of IC card water meters generally fail to simultaneously address the core issue of stable fixation during testing and safety protection during operation. There is an urgent need for a dedicated device that can securely clamp the IC water meter and provide reliable and safe isolation for testing personnel. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides an IC card water meter sealing test fixture, which aims to improve the problems of inaccurate test results due to unstable fixing and lack of safety protection for test personnel. This utility model aims to provide an IC card water meter sealing test fixture with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an IC card water meter sealing test fixture, comprising: a base, and a placement seat disposed on the base; further comprising two oppositely disposed fixing components and a protective component rotatably connected to the base.

[0008] Each of the fixing components includes a threaded rod, a movable plate, and a knob fixed to the base; the movable plate is provided with an elastic pad; the movable plate is sleeved on the threaded rod; the knob is threadedly engaged with the threaded rod, and the knob abuts against and drives the movable plate to move axially along the threaded rod.

[0009] Furthermore, the protective assembly includes two protective covers that can cooperate with each other in a closed position to cover the IC water meter.

[0010] Preferably, the fixing component further includes a connecting rod, one end of which is fixedly connected to the movable plate and the other end of which is fixedly connected to the elastic pad.

[0011] Preferably, the axis of the connecting rod is perpendicular to the axis of the threaded rod.

[0012] Preferably, the movable plate has a through hole for the threaded rod to pass through, and the movable plate is slidably mounted on the threaded rod via the through hole.

[0013] Preferably, the protective assembly further includes a pin and a connecting plate; each of the protective covers rotates about a pin fixed to the base via a connecting plate.

[0014] Preferably, the protective assembly further includes a snap fastener for use at the two protective covers, preferably positioned at the top opposite edges of the two protective covers.

[0015] Preferably, the connecting plate is fixedly connected to the outer wall of the protective cover.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting up symmetrical fixing components, the movable plate with elastic pads is driven by the cooperation of threaded rod and knob to clamp the IC water meter from both sides, which solves the problems of unstable clamping and water meter shaking during testing in the prior art, resulting in inaccurate test results. It achieves the effect of stable and reliable clamping and improved accuracy of sealing test.

[0017] 2. This utility model, by setting two protective covers that can be opened, closed, rotated and locked together by buckles, completely encloses and seals the IC water meter during testing, solving the problem of lack of safety protection in the prior art and the high-pressure water flow generated by leakage or rupture of the water meter during testing, which may injure the test personnel. It achieves the effect of effectively isolating danger and ensuring the personal safety of operators. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 This utility model provides a fixing fixture for testing the sealing performance of IC card water meters, which aims to solve the problems of existing testing fixtures being unstable and prone to shaking when conducting sealing performance tests on IC card water meters, and lacking safety protection for testing personnel.

[0021] like Figure 1 and Figure 2 As shown, an IC card water meter sealing test fixture includes a base 1, two fixing components 4 disposed opposite to each other on the base 1, and a protective component 3 rotatably connected to the base 1. A placement seat 5 for initially positioning the IC water meter 2 is provided on the top surface of the base 1.

[0022] The fixing component 4 is used to clamp the IC water meter 2 placed on the placement base 5 from both sides. Each fixing component 4 includes a threaded rod 402 fixed to the base 1, a movable plate 401 and a knob 403. The movable plate 401 is sleeved on the threaded rod 402 and has a through hole for the threaded rod 402 to pass through. The movable plate 401 is slidably mounted on the threaded rod 402 through the through hole. The knob 403 is threadedly engaged with the threaded rod 402 and the knob 403 abuts against and drives the movable plate 401 to move axially along the threaded rod 402. The movable plate 401 is provided with an elastic pad 405 for abutting against the IC water meter 2.

[0023] To connect the movable plate 401 and the elastic pad 405, the fixing assembly 4 also includes a connecting rod 404. One end of the connecting rod 404 is fixedly connected to the movable plate 401, and the other end of the connecting rod 404 is fixedly connected to the elastic pad 405. The axis of the connecting rod 404 is perpendicular to the axis of the threaded rod 402. When the knob 403 is rotated, the knob 403 moves on the threaded rod 402 and pushes the movable plate 401, thereby driving the connecting rod 404 and the elastic pad 405 to move synchronously, so as to clamp or release the IC water meter 2.

[0024] The protective assembly 3 is used to safely isolate the IC water meter 2 during the sealing test. The protective assembly 3 includes two protective covers 302, which can cooperate with each other in the closed position to form a cover to house the IC water meter 2 inside the cover. The protective assembly 3 also includes a pin 304 and a connecting plate 303. Each protective cover 302 rotates around a pin 304 fixed on the base 1 via a connecting plate 303. The connecting plate 303 is fixedly connected to the outer wall of the protective cover 302, thereby realizing the opening and closing action of the protective cover 302. In order to lock the two protective covers 302 in the closed state, the protective assembly 3 also includes a buckle 301, which is set at the top opposite edges of the two protective covers 302.

[0025] Please refer to the following carefully. Figure 3 and Figure 4The reliable clamping function of the fixed component 4 is achieved through the precise linkage between the threaded rod 402, the knob 403, the movable plate 401, the connecting rod 404, and the elastic pad 405. Specifically, the threaded rod 402 is fixedly connected to the base 1, the movable plate 401 is slidably mounted on the threaded rod 402 through a through hole, and the knob 403 is threadedly engaged with the threaded rod 402. During rotation, the knob 403 can move along the axial direction of the threaded rod 402, and the end face of the knob 403 always abuts against the outer side of the movable plate 401, thereby driving the movable plate 401 to move synchronously in a straight line. The movable plate 401 drives the elastic pad 405 to move through the fixedly connected connecting rod 404. This method of applying clamping force using threaded transmission is not only labor-saving to operate, but also provides accurate and stable clamping force, ensuring that the IC water meter 2 will not displace when subjected to internal water pressure.

[0026] The safety isolation function of the protective component 3 is achieved through the coordinated work of two protective covers 302, a connecting plate 303, a pin 304, and a buckle 301. Specifically, each protective cover 302 is rotatably connected to the base 1 via a connecting plate 303 and a pin 304. The pin 304 provides the rotation axis for the protective cover 302, allowing the protective cover 302 to be easily opened or closed. When the two protective covers 302 are closed, the buckles 301 located at the opposite edges of the top of the two protective covers 302 engage with each other, firmly locking the two protective covers 302 together to form a closed protective space. This fully enclosed protective structure can effectively block the high-pressure water jet generated by the rupture of the IC water meter 2 in extreme cases, thereby providing reliable safety for the test personnel.

[0027] In a preferred embodiment, in order to achieve stable and reliable force transmission between the movable plate 401 and the elastic pad 405, the fixing assembly 4 further includes a connecting rod 404. One end of the connecting rod 404 is fixedly connected to the movable plate 401, and the other end of the connecting rod 404 is fixedly connected to the elastic pad 405. More preferably, the axis of the connecting rod 404 is perpendicular to the axis of the threaded rod 402. This structure ensures that the linear motion of the movable plate 401 can be converted into the radial clamping action of the elastic pad 405 on the IC water meter 2 without deviation.

[0028] As another preferred embodiment, in order to ensure the stability and guidance of the movement of the movable plate 401 on the threaded rod 402, the movable plate 401 is provided with a through hole for the threaded rod 402 to pass through. The movable plate 401 is slidably mounted on the threaded rod 402 through the through hole. This engagement method restricts the degree of freedom of movement of the movable plate 401 to translation along the axial direction of the threaded rod 402, avoiding deflection or jamming when subjected to force.

[0029] As another preferred embodiment, in order to achieve a reliable and flexible opening and closing function of the protective cover 302, the protective component 3 also includes a pin 304 and a connecting plate 303. Each protective cover 302 rotates around a pin 304 fixed on the base 1 via a connecting plate 303. Specifically, the connecting plate 303 is fixedly connected to the outer side wall of the protective cover 302, thereby forming a stable hinge structure.

[0030] As another preferred embodiment, in order to ensure the locking reliability of the two protective covers 302 in the closed state, the protective component 3 also includes a buckle 301. The buckle 301 is provided on the top opposite edges of the two protective covers 302. When the two protective covers 302 are closed, the buckle 301 can conveniently fix the two protective covers 302 together to prevent the protective covers 302 from being accidentally opened due to vibration or accidental impact during the test.

[0031] Working principle: When in use, first rotate the two protective covers 302 of the protective component 3 around the pin 304 to open them, and place the IC water meter 2 on the placement seat 5 on the top of the base 1 to achieve positioning. Then, rotate the knob 403 of the fixing component 4 set on both sides of the base 1. The knob 403 moves axially along the threaded rod 402 and abuts against the movable plate 401, thereby driving the movable plate 401, the connecting rod 404 and the elastic pad 405 to move toward the IC water meter 2 until the elastic pads 405 on both sides firmly clamp the IC water meter 2. After the IC water meter 2 is fixed and the test pipeline is connected, the two protective covers 302 are closed and locked using the buckles 301 located on the opposite edges of the top of the two protective covers 302. At this time, the fixture forms a closed test environment. During the pressure sealing test, the stable clamping effect of the fixing component 4 ensures that the IC water meter 2 does not shake during the test, ensuring the accuracy of the test. At the same time, the protective structure formed by the protective covers 302 can effectively block the high-pressure water flow that may be sprayed due to potential leakage or rupture, providing safety for the operators.
