Description

Technical Field

[0001] The utility model relates to the technical field of waterproof performance testing, in particular to a multifunctional foam waterproof testing device. Background Technique

[0002] The waterproof performance of an automobile is directly related to the driving safety of the vehicle in the face of rainfall, waterlogging, etc. and the service life of mechanical components. Good waterproof performance can effectively prevent water from entering the vehicle interior, avoid problems such as electrical system short circuits and engine water ingress, and improve the reliability and stability of the vehicle in harsh environments.

[0003] As a functional material with shock absorption, sound insulation, sealing and waterproofing, and light weight, foam is widely used in the automotive industry. During the production process of foam, waterproof performance testing is required. In the existing waterproof performance testing devices for foam, it is necessary to pour the test liquid into the foam to be tested. In the prior art, this process is generally completed manually. Since the foam to be tested is clamped and fixed between the clamping plates, and the gap between the clamping plates is small, when pouring the test liquid manually, the test liquid is likely to spill out. Moreover, the existing device lacks a lighting device, and when the light in the test environment is weak, it is inconvenient for the staff to observe the test process. Therefore, we propose a multifunctional foam waterproof testing device. Content of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-7, the present utility model provides a technical solution: a multifunctional foam waterproof testing device, mainly composed of a testing box 1, a lighting device 2, a waterproof testing fixture 3, a base 4, a liquid leakage collection tank 5, a back plate 6, a test liquid filling device 7 and a controller 8. Among them, the number of the lighting device 2, the waterproof testing fixture 3, the base 4, the liquid leakage collection tank 5, the back plate 6 and the controller 8 are all set to four, and they correspond one by one. The lighting device 2 is set as an LED lamp, which can improve the light in the testing environment during operation, facilitating the staff to observe. The waterproof testing fixture 3 is installed inside the base 4, and the liquid leakage collection tank 5 is arranged below the waterproof testing fixture 3. The liquid leakage collection tank 5 is internally provided with absorbent paper for absorbing the leaked ink (test liquid). The back plate 6 is arranged between the waterproof testing fixture 3 and the test liquid filling device 7. The back plate 6 is an opaque structure, and the color can be set to a material or color that is convenient for observing the leakage of the test liquid. The test liquid filling device 7 is located in the middle. The liquid outlet end of the test liquid filling device 7 can rotate (it can be rotated manually or electrically, and the electrical rotation structure is not shown in the figure). After each rotation, the liquid outlet end of the test liquid filling device 7 is located above the test foam 9 in the waterproof testing fixture 3. In this way, one test liquid filling device 7 can provide test liquid for multiple groups of tests, and the test liquid is pumped to the test foam 9 electrically. The controller 8 can control the lighting device 2 and the test liquid filling device 7 to be turned on and off simultaneously;

[0028] Secondly, the testing box 1 includes a bottom plate 11. Multiple columns 12 are installed on the upper part of the bottom plate 11. The lighting device 2 is installed inside the columns 12. A side plate 13 is rotatably connected to the outside of the columns 12. The top ends of multiple columns 12 are jointly slidably connected with a cover plate 16. A handle 14 is installed on the surface of the side plate 13, and a reserved hole 15 (the controller 8 is installed in the reserved hole 15) is penetrated through the bottom of the side plate 13. The side plate 13 in each direction can be rotated and opened, and the cover plate 16 can be slidably opened, so as to facilitate the taking and placing of the waterproof testing fixture 3. The side plate 13 and the cover plate 16 are both transparent structures, which can facilitate the staff to observe the change of the liquid level of the test liquid during the testing process;

[0029] Furthermore, the waterproof testing fixture 3 includes a front clamping plate 31 and a rear clamping plate 32. Fastening holes 33 are reserved inside the front clamping plate 31 and the rear clamping plate 32. A gasket 35 is arranged at the position corresponding to the fastening holes 33 between the front clamping plate 31 and the rear clamping plate 32. The front clamping plate 31 and the rear clamping plate 32 are connected by fastening bolts 34 and fastening nuts 36. When installing the test foam 9, first place the test foam on the rear clamping plate 32, then close the front clamping plate 31, pass the fastening bolt 34 through the fastening hole 33 and the gasket 35, and finally tighten the fastening nut 36. The thickness of the gasket 35 is adapted to the target thickness of the test foam 9 after compression.

[0030] The device 7 for injecting the liquid to be tested includes a storage container 71. A limit seat 72 is connected to the upper part of the storage container 71. A pump body 73 is installed inside the limit seat 72. The liquid inlet end of the pump body 73 is connected with a liquid suction pipe 74. The liquid suction end of the liquid suction pipe 74 extends into the storage container 71. The liquid outlet end of the pump body 73 is rotatably connected with an infusion pipe 75 through a sealing rubber ring. A protective cover 76 is rotatably connected inside the limit seat 72. The infusion pipe 75 is fixedly connected with the protective cover 76. A clamping protrusion 77 is connected to the bottom end of the protective cover 76. The clamping protrusion 77 is clamped inside the limit seat 72. And a ball 78 is arranged below the clamping protrusion 77. Arc grooves adapted to the ball 78 are arranged at the bottom end of the clamping protrusion 77 and the bottom end of the limit seat 72. The ball 78 rolls inside the arc groove.

[0031] When the device 7 for injecting the liquid to be tested is working, the storage container 71 stores the liquid to be tested (distilled water added with dark blue ink). When it is necessary to inject the liquid to be tested into the foam 9 to be tested in the waterproof test fixture 3, the pump body 73 is started through the controller 8. The pump body 73 sucks the liquid to be tested in the storage container 71 through the liquid suction pipe 74 and conveys it through the infusion pipe 75. The outlet of the infusion pipe 75 is located above the foam 9 to be tested (the foam 9 to be tested is prepared in a "U" shape, and the liquid to be tested is located in the "U" - shaped groove). When it is necessary to inject the liquid to be tested into other waterproof test fixtures 3, the infusion pipe 75 is rotated to drive the protective cover 76 to rotate synchronously. The ball 78 arranged between the bottom end of the protective cover 76 and the limit seat 72 rolls, and then the infusion pipe 75 can be rotated until the infusion pipe 75 rotates to the position directly above the waterproof test fixture 3 (that is, between the front clamping plate 31 and the rear clamping plate 32).

[0032] During use, the "U" - shaped foam 9 to be tested is assembled into the waterproof test fixture 3, and then the waterproof test fixture 3 is installed inside the base 4. Through the device 7 for injecting the liquid to be tested, the liquid to be tested is injected into the "U" - shaped foam 9 to be tested. After the liquid level of the liquid to be tested reaches the designed height, the staff observes whether the liquid level of the liquid to be tested drops within the set time. If it drops, it means that the foam 9 to be tested leaks water and the waterproof test is unqualified.
