Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air bag testing, in particular to a massage belt air bag pressure leakage testing device. Background Art
[0002] A massage belt is a product used to provide waist massage and relief. It usually uses airbag inflation to simulate massage techniques. This product is usually designed with multiple airbags, which are placed in specific positions inside the belt to compress and massage the user's waist when inflated. The massage belt is filled with airbags, and the corresponding massage effect is achieved by changing the air pressure inside the airbags. Therefore, the sealing performance of the airbags directly affects the service life of the massage belt. Therefore, the airbags of the massage belt need to be subjected to corresponding leakage tests after production.
[0003] As disclosed in Chinese Patent Publication No. (CN218470115U), a massage belt airbag leakage tester comprises a shell; an air pressure valve arranged on the shell, used to connect with an external air source and to control the ventilation volume of the test fixture; an electrically controlled pneumatic valve connected to the air pressure valve, used for electrically controlled ventilation; a first pressure gauge and a second pressure gauge connected to one end of the electrically controlled pneumatic valve in sequence; an inflation nozzle connected to the second pressure gauge; and a power supply, wherein the power supply is electrically connected to the electrically controlled pneumatic valve and the second pressure gauge, and the electrical signal is connected to a switch button. The utility model is provided with two pressure gauges, which can, on the one hand, serve as a reference to determine whether the pressure gauges are faulty; on the other hand, the second pressure gauge is electrically connected to the power supply signal, and when the massage airbag reaches the set air pressure value, the electrical signal can be sent to the power supply, and after receiving the signal, the power supply drives the electric pneumatic valve to stop the continued inflow of air, which has the advantage of high test accuracy.
[0004] However, as in the above patent, there is still a problem of poor pressure leakage detection effect for the massage belt airbag. For example, in the above patent, air is directly inflated in the airbag, and the air pressure change is observed during the inflation process to detect whether there is a leakage in the airbag. However, this method can only detect leakage of the airbag in a normal state. The massage belt airbag needs to be worn on the wearer's waist. When inflated, it will be subjected to the dual pressure of waist abutment and fixing part restraint, causing the airbag to be pressurized, which is more prone to leakage. The existing technology cannot effectively simulate massage usage, affecting the leakage detection accuracy of the massage belt airbag. Utility Model Content

[0029] The working principle of the above embodiment is:
[0030] (1) When the massage belt airbag is used for pressure testing, the placement rack 241 is first pulled out to the outside of the test box 1 through the pull plate 243, and then the massage belt airbag is placed on the placement rack 241. The pull plate 243 is further pushed to push the placement rack 241 to slide along the outside of the slide rail through the slider 244 to bring the airbag into the test box 1.

In this way, airbag leakage detection under a pressure environment can detect whether there is a leak in time.
[0031] (2) When the massage belt airbag is used for leakage test, the massage belt airbag is brought into the test box 1 through the supporting member 24. After the airbag is brought in, the slider 244 cooperates with the slide rail to position the inflation tube on the airbag and insert it into the connecting jack, so that the airbag inflation tube can be extended to the outside of the test box 1 for connection and inflation. The connecting tube 33 and the airbag inflation tube are combined and connected through the pipe quick connector 34.
