Description

Technical Field

[0001] This utility model relates to the field of hose testing technology, and specifically to a sealing hose testing device. Background Technology

[0002] Water hoses used to be straight-ended, but with the upgrading of water hose products, tapered-ended hoses are now more commonly used. Regardless of whether they are straight-ended or tapered-ended, the airtightness of the hose must be tested. The airtightness testing fixture for straight-ended hoses involves sealing the inner wall of the hose, then injecting gas at a certain pressure using external equipment to test the airtightness.

[0003] Current air tightness testing devices often encounter air leakage problems at both ends of the inlet pipe when testing water pipes, which affects the accuracy of the air tightness test; the testing equipment can usually only test a single type of water pipe, and its versatility is not strong.

[0021] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0022] Example 1

[0023] A sealant hose detection device, comprising: a detection pool 1 and detection mechanisms arranged on both sides of the detection pool 1. The detection mechanisms include a fixed detection module 21 and a movable detection module 22. The fixed detection module 21 includes a lifting cylinder 211 arranged at one end of the detection pool 1 and a mounting plate 212 arranged at the end of the piston rod of the lifting cylinder. The movable detection module 22 includes a lifting cylinder 221 arranged at the other end of the detection pool 1 and a mounting plate 222 arranged at the end of the piston rod of the lifting cylinder 221. Sealing detection components 3 are arranged on both the mounting plate 212 and the mounting plate 222. The sealing detection component 3 of the fixed detection module 21 is fixedly arranged at the lower end of the mounting plate 212. The sealing detection component 3 of the movable detection module 22 is slidably arranged at the lower end of the mounting plate 222 and is locked by a limiting member. The sealing detection component 3 includes a fixing plate 31, a mounting seat 32 arranged on the fixing plate 31, a sealing housing 33 threadedly connected to the mounting seat 32, a support air inlet rod 34 arranged in the middle of the sealing housing 33, a sealing airbag 35 arranged in the sealing housing 33, and an air inlet pipe 36 connected to the support air inlet rod 34 and the sealing airbag 35 through a pipeline.

[0024] As Figures 1-4 shown, in the actual use process of the present utility model, first, according to the length of the hose to be detected, slide the sealing detection component 3 of the movable detection module detection mechanism 22 to adjust the distance between the two detection components to match the hose length, and lock the position through the limiting member.

[0025] Secondly, respectively put the two ends of the hose onto the outer ends of the sealing housings 33 of the sealing detection components 3 of the two detection mechanisms, and ensure that the insertion depth meets the standard.

[0026] Thirdly, inflate the sealing airbags 35 on both sides through the air inlet pipe detection mechanism 36. After the airbags expand, they closely adhere to the inner wall of the hose and the outer wall of the sealing housing 33 to form seals at both ends. At this time, the inside of the hose is isolated from the water body in the detection pool, and only communicates with the external air source through the support air inlet rod detection mechanism 34.

[0027] Subsequently, simultaneously start the lifting cylinder 211 of the detection mechanism and the lifting cylinder 221 of the detection mechanism. The piston rods extend to drive the mounting plate 212 of the detection mechanism and the mounting plate 222 of the detection mechanism to descend, so that the hose is completely immersed in the clear water of the detection pool 1 of the detection mechanism and remains stable. Compressed air is introduced into the hose through the support air inlet rod detection mechanism 34 and kept under pressure, and observe the surface state of the hose in the water:

[0028] No bubbles: The sealing performance of the hose is qualified;

[0029] Bubbles present: The location where bubbles are generated is the leak point. Record the location and determine that the product is unqualified.

[0030] This invention can be adapted to sealing tubes of different lengths and inner diameters, achieves reliable sealing through an airbag, provides intuitive and accurate water immersion testing, and reduces manpower through automated operation, thereby improving testing efficiency and accuracy.

[0031] As a further preferred embodiment, an adjustment groove 2221 is provided through the mounting plate 222, and the upper end of the fixing plate 31 of the moving detection module 22 is slidably adapted to the adjustment groove 2221 and locked by a limiting bolt.

[0032] Specifically, the adjustment groove detection mechanism 2221 has symmetrical scale lines on both sides, and the fixed plate detection mechanism 31 has an indicator arrow on its side, which can intuitively read the adjustment distance and facilitate quick matching of rubber tubes of different lengths. When the position is adjusted to the correct position, it is locked by the limit bolt that passes through the slider. The end of the bolt is tightly attached to the upper surface of the mounting plate detection mechanism 222, generating friction to fix the slider position.

[0033] As a further preferred embodiment, the mounting base 32 includes a base body 321, which is provided with a threaded portion 322, a strip-shaped air inlet groove 323 and a circular air inlet hole 324 from the outside to the inside. The air inlet pipe 36 includes an air inlet pipe 361 connected to the supporting air inlet rod 34 and an air inlet pipe 362 connected to the sealing airbag 35. The air inlet pipe 361 communicates with the circular air inlet hole 324 and the air inlet pipe 362 communicates with the strip-shaped air inlet groove 323.

[0034] Specifically, the mounting base 32 supports quick replacement according to the hose diameter. When replacing, simply tighten the thread to complete the adaptation, without the need to adjust the air circuit structure.

[0035] After replacement, when the second intake pipe detection mechanism 362 is ventilated first, the gas is evenly filled into the sealing airbag detection mechanism 35 through the annular flow of the strip-shaped intake groove detection mechanism 323 of the mounting base detection mechanism 32. This ensures that the airbag expands synchronously along the circumference and fits tightly against the outer wall of the hose, matching the airbag size of the corresponding pipe diameter. After the seal is stable, the first intake pipe detection mechanism 361 is ventilated, and the gas enters the support intake rod detection mechanism 34 with the matching pipe diameter through the circular intake hole detection mechanism 324, and is stably filled into the hose.

[0036] As a further preferred embodiment, the detection pool 1 is provided with at least two sets of arc-shaped support members 4.

[0037] Specifically, when the hose is immersed in water, its bottom fits against the curved plate, forming multi-point support. This prevents the long hose from bending in the middle due to its own weight, ensuring that the hose remains horizontal and that all parts of its surface are covered by water. This prevents air bubbles from accumulating in blind spots caused by bending, thus improving the completeness of leak detection.

[0038] As a further preferred embodiment, the fixing plate 31 includes a first fixing plate 311 and a second fixing plate 312. The first fixing plate 311 is disposed below the first mounting plate 212 or the second mounting plate 222. The second fixing plate 312 is slidably mounted inside the first mounting plate 212, and the mounting base 32 is fixed to the second fixing plate 312. (Detection mechanism)

[0039] As a further preferred embodiment, a sealing gasket 37 is provided between the supporting air intake rod 34 and the sealing housing 33.

[0040] Specifically, the sealing gasket testing mechanism 37 can fill the assembly gap between the two, preventing the testing gas from leaking from the connection.

[0041] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
