Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a waterproof detection device for a plug power cord. Background Art

[0002] As a key component connecting power sources to devices, the waterproof performance of power cords directly impacts the product's lifespan and safety. This is especially true for plug-in power devices often used outdoors or in humid environments, where waterproofing requirements are particularly stringent. If the power plug is not properly sealed, moisture can enter, causing a short circuit or other electrical failure, posing a safety hazard. Waterproofing testing ensures that power plugs are properly sealed, preventing moisture intrusion and ensuring the proper functioning of the appliance and user safety.

[0003] Uneven plug surfaces or twisted inserts can easily reduce the waterproof performance of plug cords, compromising safety. Existing testing methods often rely on manual immersion or observation, which is inefficient and difficult to guarantee accurate test results. To address this issue, a device for testing the waterproofness of power cords is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a plug power cord waterproof detection device, comprising a detection box and a gasket, wherein the bottom of the inner wall of the detection box is fixedly connected to a detection seat, the top surface of the detection seat is provided with a groove, the detection seat is provided with a jack, and the jack is located inside the groove, the detection box is provided with a box cover, and a gas flow detector is provided on the top of the box cover;

[0006] The detection seat is hollow, and a ferrule is fixedly connected to the top of the inner wall of the detection seat. A sealing sticker is adhered to the inner wall of the ferrule. An air inlet pipe is fixedly connected to the outer wall of the detection seat. The end of the air inlet pipe away from the detection seat extends to the outside of the detection box. A sealing ring is provided on the outer wall of the air inlet pipe. A sealing groove is opened on the outer wall of the detection box. The sealing ring is fixedly connected to the inner side of the sealing groove.

[0007] Preferably, the top of the detection seat is rotatably connected to a limit block, and there are two limit blocks. The two limit blocks are axially symmetrically arranged along the center line of the detection seat, and the limit block extends from one end of the detection seat to above the groove.

[0008] Preferably, an annular groove is formed at the upper end of the detection box, a rubber pad is bonded to the bottom surface of the box cover, and the rubber pad abuts against the inner wall of the box cover.

[0009] Preferably, the outer wall of the box cover is symmetrically provided with buckle plates, the buckle plates are hinged to the box cover, the outer wall of the detection box is symmetrically connected with buckles, and the buckle plates are buckled with the buckles.

[0010] Preferably, the gasket can be snap-fitted to the inner wall of the groove.

[0011] Preferably, a bottom pad is bonded to the bottom surface of the detection box.

[0012] Compared with related technologies, the plug power cord waterproof detection device provided by the utility model has the following beneficial effects:

[0013] 1. When in use, put the corresponding gasket in the groove and seal the extra jacks to be tested to prevent air leakage during the air tightness test. When plugging the plug wire into the corresponding jack on the test socket, ensure the sealing through the ferrule and the sealing sticker on its inner side to prevent gas leakage from causing errors in the test results. After the connection is completed, connect the air inlet pipe to the inflation port of the external inflation device, and fill a part of the gas into the test socket through the inflation device. Then use the air flow detector to detect the gas content inside the test box. By detecting whether there is gas escape, the waterproof performance of the product is judged. This detection method is not only efficient, but also has a small error and strong practicality.

[0014] 2. When the box cover is pressed against the inner wall of the ring groove through the sealing sticker, a sealed clamping state is formed. Then the buckles on the box cover are clamped with the buckle plates on both sides of the test box to seal the test box to prevent some gas from escaping from the test box and reduce the probability of error. After the gasket is placed in the groove, the gasket can be pressed tightly by the limit block on the test seat so that the gasket can be tightly attached to the inner wall of the groove to prevent air leakage, thereby improving the accuracy of the plug wire sealing test.
