[0021] Example 1

[0022] Reference Figures 1-4 This embodiment provides a quick-connect Hall flow meter, including a quick-change structure 100. The quick-change structure 100 includes a support ring 101 and a sealing ring 102. The sealing ring 102 is snapped into one end of the support ring 101, and a retaining ring 103 is provided at the other end of the support ring 101.

[0023] It should be noted that the retaining ring 103 can be fixed together with the support ring 101. The retaining ring 103 can be fixed by the support ring 101 and the metal sleeve 104 pressing and limiting it by snapping.

[0024] The retaining ring 103 includes a reed 103a and a plurality of retaining claws 103b disposed inside the reed 103a, the retaining claws 103b being arranged in an array along the circumference of the reed 103a.

[0025] The support ring 101 includes a fixed ring plate 101a and a hook plate 101b disposed on one side of the fixed ring plate 101a. The inner side of the fixed ring plate 101a is provided with a first conical groove 101c, and the outer side of the fixed ring plate 101a is provided with an outer ring groove 101d.

[0026] The hook plate is L-shaped and is used to connect the support ring 101 to the sealing ring 102.

[0027] The inner wall of the sealing ring 102 is provided with a hook groove 102a, and the hook plate 101b is embedded in the hook groove 102a. The inner side of the sealing ring 102 is provided with a second conical groove 102b, and one end of the sealing ring 102 is provided with a pressure-adjusting ring groove 102c.

[0028] The pressure-adjusting ring groove 102c is set at the thicker end of the sealing ring, that is, facing the inside of the infusion tube 202, so that when the water pressure inside the shell 200 increases, the sealing ring tightly wraps the water tube, further achieving the sealing effect. Therefore, the sealing effect is better as the pressure increases.

[0029] The claw 103b is correspondingly disposed inside the second conical groove 102b. The second conical groove 102b allows the claw 103b to be pressed and expand outwards to approach the inner wall of the second conical groove 102b.

[0030] The quick-change structure 100 also includes a metal sleeve 104, which includes a limiting ring plate 104a and an extension ring plate 104b disposed on one side of the limiting ring plate 104a. The extension ring plate 104b is embedded in the outer ring groove 101d, and a triangular barb fixing mechanism 104c is also provided on the outer side of the extension ring plate 104b.

[0031] The metal sleeve 104 is used to limit and fix the support ring 101 and the sealing ring 102 in the infusion tube 202. The metal sleeve 104 and the infusion tube 202 are fitted and fixedly connected by the triangular barb fixing mechanism 104c. The metal sleeve 104 is set at the end of the infusion tube 202.

[0032] The quick-change structure 100 also includes a button 105, which includes an end plate 105a and a compression ring plate 105b disposed on one side of the end plate 105a. A conical surface 105c is provided on the outer side of the end of the compression ring plate 105b, and a limit block 105d is also provided on the outer side of the compression ring plate 105b.

[0033] The conical surface 105c allows the jaw 103b to have a deformation guide.

[0034] The inner side of the extension ring plate 104b is provided with a first stepped groove 104d and a second stepped groove 104e. The spring 103a is disposed in the first stepped groove 104d, and the limiting block 105d is embedded in the second stepped groove 104e.

[0035] The limiting block 105d is used to prevent the button 105 from falling off. The compression ring plate 105b is embedded inside the limiting ring plate 104a and provides a guiding function for the button 105, so that the button 105 can be pushed axially.

[0036] It also includes a housing 200, which includes a measuring chamber 201 and an infusion tube 202 disposed on the measuring chamber 201. A measuring element 203 is disposed in the measuring chamber 201.

[0037] It should be noted that the measuring component 203 is the main body for realizing the flow measurement function. Its model, working principle and wiring method are irrelevant to the technical problem to be solved in this application, and will not be described in detail here.

[0038] The inner wall of the infusion tube 202 is provided with a fixing ring groove 202a, the extension ring plate 104b, the support ring 101 and the sealing ring 102 are provided in the fixing ring groove 202a, the inner wall of the fixing ring groove 202a is provided with a triangular ring groove 202b, and the triangular barb fixing mechanism 104c is embedded in the triangular ring groove 202b.

[0039] It also includes a water pipe 300, which passes through the button 105, the snap ring 103, the support ring 101, and the sealing ring 102.

[0040] The flow meter interface incorporates a quick-connect structure suitable for PU or nylon tubing, such as... Figure 1 As shown, when it is necessary to connect and install the water pipe 300, simply insert the water pipe 300 into the quick-connect structure 100. Specifically, the water pipe 300 passes through the compression ring plate 105b and the compression claw 103b, and passes through the inner wall of the hook plate 101b to compress the sealing ring 102 for installation. The smooth outer circle of the water pipe contacts the sealing ring 102, which plays a sealing role and ensures that the liquid will not leak. When the water pipe 300 is pulled back, the claw 103b can hold the water pipe 300 to ensure that it will not fall off. When it is necessary to remove the water pipe 300, press the button 105, the compression ring plate 105b compresses the claw 103b outward, release the water pipe 300, and then you can pull out the water pipe 300.

[0041] The advantages of this application are: convenient installation and maintenance, eliminating the need for frequent adjustments to the installation angle to ensure a seal; low cost, requiring no additional auxiliary materials such as raw rubber tape; and excellent sealing performance, with the sealing ring having a special anti-leakage function, where the higher the pressure, the better the sealing effect. This sealing ring is V-shaped, which expands under pressure, thus enhancing the sealing effect.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
