Description

Technical Field

[0001] The utility model relates to the disassembly and assembly structure design of a pressure gauge quick connector, in particular to a quick disassembly structure for a pressure gauge quick connector. Background Technique

[0002] At present, in the verification of pressure gauges in the prior art, the verification method using an automatic pressure verification bench has become increasingly common. The key component in the pressure gauge verification bench is the pressure gauge quick connector, which mainly functions to quickly clamp the pressure gauge and supply pressure to the pressure gauge. Therefore, the pressure gauge quick connector needs to be installed not only on the automatic verification bench but also connected to the gas circuit. Currently, in the prior art, the connection method between the pressure gauge quick connector and the gas circuit mainly uses a screwed connection method. Although this can ensure airtightness, due to the different types and sizes of the pressure gauges to be inspected, it is often necessary to disassemble and replace the pressure gauge quick connector between the pressure gauge verification bench and the quick connector in the prior art, and different pressure gauge quick connectors are used to adapt to different types of pressure gauges. However, the screwed connection method requires repeated disassembly and assembly between the pressure gauge quick connector and the pipeline, and the operation is extremely cumbersome. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick disassembly structure for a pressure gauge quick connector, which can realize the quick disassembly and assembly between the pipeline and the pressure gauge quick connector while ensuring airtightness.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A quick disassembly structure for a pressure gauge quick connector, including a connection head and an interface part. An air inlet end is provided on the connection head. The interface part is a plug-in interface. The air inlet end is detachably connected to the interface part. A first recessed part is provided in the middle of the air inlet end. The side wall of the interface part abuts against a clamping part through an elastic part, and the clamping part can be clamped with the first recessed part.

[0005] Preferably, a second recessed part is provided at the bottom of the air inlet end, and the second recessed part is clamped with the bottom of the interface part.

[0006] Preferably, a sealing gasket is provided at the bottom of the air inlet end.

[0007] Preferably, the clamping part is a steel ball.

[0008] Preferably, the elastic part can be installed on the side wall of the interface part.

[0009] Preferably, the elastic part can be installed on a socket part. The socket part is slidably matched with the outer wall of the interface part. A through hole is provided on the interface part. The clamping part is located in the through hole, and the elastic part can abut against the clamping part.

[0010] Compared with the prior art, the utility model provides a quick-release structure for a pressure gauge quick connector, which has the following beneficial effects:

[0011] The utility model completes the quick disassembly and assembly with the joint part through the first recessed part provided at the air inlet end, thereby realizing the quick clamping of the quick connector. By making the second recessed part abut against the end face of the interface part, the second recessed part is kept sealed after being clamped with the interface part, thereby effectively realizing the quick clamping and disassembly of the quick connector and ensuring the sealing performance after clamping.
