Description

Technical Field

[0001] This utility model relates to the field of hose testing technology, and in particular to a hose leak detection device. Background Technology

[0002] In numerous industrial manufacturing, automotive, aerospace, medical equipment, and civilian equipment, hoses are widely used as key components for gas or liquid transmission in various fluid systems. The sealing performance and pressure-bearing capacity of hoses are directly related to the operational stability and safety of the entire system. If a hose has leakage defects, it may affect system efficiency at best, and at worst, it may cause safety accidents, resulting in equipment damage or personal injury. Therefore, sealing testing is an indispensable quality control step in the production, manufacturing, use, and maintenance of hoses.

[0003] Patent CN207703419U discloses an airtightness testing device for rubber hoses. This device includes an operating platform, a high-pressure gas collecting bottle, a first conduit, a spherical valve plate, a first through-hole, a connecting rod, an operating handle, a second through-hole, a pressure gauge, a second conduit, a nozzle, a slide, a slider, and a sealing plug. By adjusting the distance between the sealing plug and the nozzle, it can adapt to rubber hoses of different lengths for airtightness testing. While the device has a simple structure and is easy to operate, it still has some shortcomings in practical applications. During hose inflation or testing, the lack of an effective positioning and clamping structure makes the hose ends prone to bending, displacement, and other unstable connections, leading to poor sealing or distorted test results, affecting the accuracy and repeatability of the test.

[0004] Therefore, there is an urgent need to provide a hose leak detection device with positioning and clamping functions. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents where the hose lacks positioning during inflation and testing, which makes the ends of the hose prone to bending or displacement and affects the accuracy of testing, this utility model provides a hose leak detection device with positioning and clamping functions.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a hose leak detection device, comprising a mounting base plate, with symmetrically distributed first cylinders fixedly connected to one side of the top of the mounting base plate, each first cylinder having an air pump module mounted on its movable rod, and symmetrically distributed second cylinders fixedly connected to the other side of the top of the mounting base plate, each second cylinder having a pressure sensing module mounted on its movable rod. The air pump module and the pressure sensing module are respectively sealed to both ends of the hose to achieve pressurization and detection of the internal air pressure of the hose. Symmetrically distributed mounting brackets are fixedly connected to the mounting base plate between the air pump module and the pressure sensing module, each mounting bracket having a positioning clamp fixedly connected to it, and each mounting bracket having a threaded compression screw. One end of the compression screw is fixedly connected to the same positioning clamp, and the other end has an operating handle.

[0007] As a further preferred embodiment, the mounting base plate has a mounting guide groove at its bottom.

[0008] As a further preferred embodiment, the positioning clamp has an overall arc-shaped structure.

[0009] As a further preferred embodiment, the inner arc surface of the positioning clamp is provided with a filling airbag, and adjacent filling airbags are connected together and connected by a three-way air tube.

[0010] As a further preferred embodiment, the remaining end of the three-way vent pipe is provided with a sealing joint.

[0011] As a further preferred embodiment, symmetrically distributed support plates are fixedly connected to the top center of the mounting base plate.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a cylinder to realize the automatic positioning of the air pump module and the pressure sensing module, combined with the clamping structure composed of the positioning clamp and the extrusion screw, the two ends of the hose can be effectively fixed to prevent displacement or deformation during the detection process, thereby significantly improving the stability and reliability of the detection.

[0013] 2. By setting a filling airbag on the inner arc surface of the positioning clamp and connecting it to an external air source through a three-way air pipe, the airbag can be inflated after clamping to fill the gap between the clamp and the hose, thereby enhancing the clamping strength and sealing performance.

[0018] 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.

[0019] Example 1: Please refer to Figure 1 and Figure 2 A hose leak detection device includes a mounting base plate 1. The bottom of the mounting base plate 1 has a mounting guide groove for sliding the entire detection device onto a detection platform or production line guide rail, facilitating device positioning, movement, and integrated application. A first cylinder 2, symmetrically distributed on both sides, is fixedly connected to the front top of the mounting base plate 1. Each first cylinder 2 has an air pump module 3 mounted on its movable rod. A second cylinder 4, symmetrically distributed on both sides, is fixedly connected to the rear top of the mounting base plate 1. Each second cylinder 4 has a pressure sensing module 5 mounted on its movable rod. The air pump module 3 and the pressure sensing module 5 are respectively sealed to both ends of a hose 6 to pressurize and detect the internal air pressure of the hose 6. A mounting bracket 7 is symmetrically distributed front and back on the mounting base plate 1 between module 3 and the pressure sensing module 5. Each mounting bracket 7 is fixed with a positioning clamp 8. The positioning clamp 8 has an overall arc-shaped structure to better fit the outer wall of the hose 6 of different diameter specifications and improve clamping stability. Each mounting bracket 7 is threaded with a compression screw 9. One end of the compression screw 9 is fixed with the same positioning clamp 8, and the other end is provided with an operating handle 10. A receiving plate 14 is symmetrically distributed front and back on the top middle position of the mounting base plate 1 to support the middle section of the hose 6 and prevent the hose 6 from collapsing in the middle due to its own weight or clamping force during the inflation process, thereby affecting the detection accuracy and sealing effect.

[0020] When leak testing of hose 6 is required, first place hose 6 between air pump module 3 and pressure sensor module 5. Then, start the first cylinder 2 and the second cylinder 4 to move air pump module 3 and pressure sensor module 5 to both ends of hose 6 respectively, forming a sealed connection with both ends of hose 6. Next, the operator manually rotates the operating handle 10 to drive the compression screw 9 to rotate, causing the movable positioning clamp 8 to move closer to the fixed positioning clamp 8, thereby clamping and fixing both ends of hose 6 laterally to prevent bending, displacement or loosening during inflation or testing, thus improving the stability and data accuracy of the testing process. After clamping, the air pump module 3 fills the hose 6 with gas at a set pressure, while the pressure sensor module 5 records the initial air pressure value. After maintaining this pressure for a certain period of time, the data from the pressure sensor module 5 is read again. If the air pressure value remains stable, it indicates that hose 6 is well sealed and there is no leakage. If the air pressure value drops, it indicates that hose 6 has a leak point and is judged as a defective product.

[0021] Example 2: Based on Example 1, please refer to... Figure 3 The inner arc surface of the positioning clamp 8 is provided with a filling air bladder 11, which is used to fill the clamping gap between the positioning clamp 8 and the hose 6, thereby improving the clamping stability. The adjacent filling air bladders 11 are connected and communicated with a three-way air pipe 12. The remaining end of the three-way air pipe 12 is provided with a sealing joint 13 for connecting to an inflation / deflation device.

[0022] After the positioning clamp 8 is initially clamped, an external air source injects an appropriate amount of gas into the filling airbag 11 through the sealing joint 13 and the three-way air pipe 12, so that the filling airbag 11 fills the clamping gap between the positioning clamp 8 and the hose 6, thereby improving the clamping stability and achieving the best clamping state. After the test is completed, the gas in the airbag can be released through the sealing joint 13.
