Description

Technical Field

[0001] This utility model relates to the field of airtightness testing, specifically to a water tap sealing plug. Background Technology

[0002] An airtightness test plug is a key component used for testing the airtightness of pipelines or containers. It is primarily used to seal openings in pipelines or containers to prevent the entry of external dust and debris, and to ensure the accuracy of the airtightness test. Airtightness testing is a crucial step in ensuring the sealing performance of pipelines or containers and is widely used in the automotive, aerospace, electronics, and chemical industries. By detecting leaks in pipelines or containers, their safety and reliability can be ensured.

[0003] Patent CN222579539U discloses a rapid testing device for the airtightness of a battery pack liquid cooling plate, including a clamping mechanism and an airtight plug. The clamping mechanism includes a control component, a connecting part, and a pressing part. The connecting part and the pressing part are hinged together. Both the connecting part and the pressing part are drivenly connected to the control component. The control component is used to push the connecting part and the pressing part to rotate in opposite directions so that the pressing part abuts against the liquid cooling plate.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0025] See Figure 1-4 The water tap sealing plug shown includes a base 1. The first end of the base 1 is provided with a sliding hole 4, and the upper surface of the second end is provided with a first U-shaped groove 12. The base 1 is also provided with a second U-shaped groove 13 that penetrates the first U-shaped groove 12. The two ends of the second U-shaped groove 13 are connected. An air inlet sealing head 5 is slidably inserted into the sliding hole 4. A tightening sealing head 11 is installed at the front end of the air inlet sealing head 5. The first end of the base 1 is also provided with a vertically penetrating opening 3. Shaft holes are provided on both sides of the opening 3. A pin 2 is inserted into the shaft hole. A clamping cam 9 is sleeved on the pin 2. A pressure arm 10 is fixed to one side of the clamping cam 9. A quick-connect interface 8 is provided on the side of the air inlet sealing head 5. A first air hole 15 communicating with the quick-connect interface 8 is provided at the end of the air inlet sealing head 5 facing the tightening sealing head 11. A second air hole 17 penetrating through is provided on the tightening sealing head 11.

[0026] By implementing the above technical solution, the outer end of the water nozzle with an outer ring 16 can be sealed. In use, the outer ring 16 of the water nozzle is locked in the first U-shaped groove 12, and the water nozzle tube 14 is mounted in the second U-shaped groove 13. The inner end of the water nozzle tube 14 contacts the sealing head 11. By rotating the pressure arm 10 downward, the side with the larger outer diameter of the pressure cam 9 rotates to make tight contact with the outer end of the air inlet sealing head 5. During the process of the air inlet sealing head 5 being pressed, it has a displacement towards the water nozzle tube 14 and pushes the sealing head 11 to press against the inner end of the water nozzle tube 14, making sealing contact with the end face of the water nozzle tube 14 to achieve sealing. Then, a standard quick-connect connector is inserted into the quick-connect interface 8. Air is delivered into the water nozzle through the first air hole 15 and the second air hole 17 by the air pump connected to the standard quick-connect connector, thereby testing the air tightness. The water nozzle sealing plug uses the self-locking feature of the cam to ensure the stability of the pressing connection. The overall structure is simple and convenient to use, disassemble and replace. Since the sealing surface of the top sealing head 11 is the end face of the water faucet pipe 14, it does not contact the inner or outer wall of the water faucet pipe 14. The sealing contact area is small, which allows for the detection of pinhole leakage defects near the port on the water faucet wall, thus ensuring product quality.

[0027] In this embodiment, the second U-shaped groove 13 has a through groove 7 at one end facing the clamping cam 9; the side of the air intake sealing head 5 has a side groove 6 perpendicular to the quick-connect interface 8 at the position of the quick-connect interface 8, the bottom surface of the side groove 6 is flat, and it is through the groove from left to right. This arrangement facilitates the insertion of the standard quick-connect connector.

[0028] In this invention, the quick-connect interface 8 can be provided with an internal thread for threaded installation of a quick-connect female connector. A sealing ring is fitted onto the stud at the lower end of the quick-connect female connector. When the screw is tightened, the sealing ring seals the connection between the female connector and the bottom surface of the side groove 6, preventing air leakage. A quick-connect male connector can then be connected to the quick-connect female connector for rapid insertion.

[0029] In this invention, the intake sealing head 5 has a groove for embedding into the tightening sealing head 11 at one end facing the tightening sealing head 11; the tightening sealing head 11 protrudes from the groove, and the diameter of the tightening sealing head 11 is not greater than the width of the second U-shaped groove 13. This design allows the tightening sealing head 11 to be directly inserted into the groove, enabling quick assembly and facilitating disassembly and replacement.

[0030] In this invention, the bottom cross-section of the base 1 is an isosceles trapezoid 18. This design increases the strength of the base 1.

[0031] In this invention, the first vent 15 and the second vent 17 are coaxially arranged and have the same diameter. Furthermore, the first vent 15 and the second vent 17 are also coaxially arranged with the sliding hole 4.

[0032] In this invention, the width of the opening 3 is smaller than the inner diameter of the sliding hole 4. This arrangement minimizes the disruption of the arc-shaped inner wall structure of the sliding hole 4 caused by the opening 3.

[0033] In this invention, the tightening sealing head 11 is a rubber tightening head. While achieving a seal, the tightening sealing head 11 directly contacts the end face of the water nozzle, ensuring that no scratches are left.

[0034] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0036] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
