Referring to fig. 1 and 2, the first embodiment provides a self-locking device for a gas pipe joint, which includes a gas pipe joint 100 and a self-locking assembly; the outer wall of the air pipe connector 100 is provided with a clamping groove 110, and the air pipe connector 100 is used for being inserted into an air pipe connecting hole of a component to be connected; the self-locking assembly is used for being installed on the to-be-connected part and comprises a clamping structure capable of generating elastic deformation, and the clamping structure can be clamped into the clamping groove 110 under mutual extrusion with the outer wall of the air pipe connector 100.

In the self-locking device for the air pipe connector provided by the embodiment, when the self-locking device is used specifically, the self-locking assembly is installed on a to-be-connected component, the air pipe connector 100 is inserted into an air pipe connecting hole of the to-be-connected component, in the process, the clamping structure can generate mutual extrusion acting force with the outer wall of the air pipe connector 100, and the clamping groove 110 is formed in the outer wall of the air pipe connector 100, so that after the air pipe connector 100 is inserted in place, the clamping structure can be clamped into the clamping groove 110 to form self-locking, and the connection reliability of the air pipe connector 100 on the air pipe connecting hole of the to-be-connected component is improved; meanwhile, when the clamping structure of the self-locking assembly is clamped into the clamping groove 110, sound is generated due to mutual extrusion acting force between the clamping structure and the clamping structure, a prompt effect is achieved, and therefore user experience is improved.

In an embodiment of the present application, referring to fig. 3, the clamping structure includes an elastic member 210, a first end of the elastic member 210 is fixed relative to the component to be connected, and a second end of the elastic member 210 is provided with a clamping portion 220; the elastic member 210 is compressed or released, so that the locking portion 220 can be separated from or slid into the locking slot 110.

Alternatively, the elastic member 210 may be a spiral spring, and the spring has a first end and a second end along two ends of the spiral line.

In brief, taking a spring as an example, when the spring is compressed, since the first end of the spring is fixed relative to the component to be connected, that is, the position is not changed, at this time, the length of the spring is shortened, so that the clamping portion 220 at the second end of the spring can be separated from the clamping slot 110; conversely, when the spring returns to the initial length, the length of the spring is extended when the spring is compressed, and at this time, the engaging portion 220 of the second end of the spring can slide into the engaging groove 110. In this embodiment, the elastic deformation direction of the clamping structure is perpendicular to the insertion and extraction direction of the air pipe joint 100, and the clamping portion 220 of the elastic member 210 can be conveniently separated from the slot 110 or slide into the slot 110, and meanwhile, when the clamping portion 220 of the elastic member 210 slides into the slot 110, a force in the radial direction can be applied to the slot 110 of the air pipe joint 100, so that the connection stability of the air pipe joint 100 is good.

The installation hole 231 is used for limiting the elastic deformation of the elastic element 210, so that the elastic element 210 can be compressed or released along the axial direction of the elastic element, and the elastic element is not deviated in the process.

In brief, when the elastic member 210 is compressed, at least a portion of the clamping portion 220 is retracted into the mounting hole 231; on the contrary, when the elastic member 210 is released, at least a portion of the clamping portion 220 protrudes out of the mounting hole 231 and can slide into the clamping slot 110.

Alternatively, the elastic member 210 and the clamping portion 220 may adopt an integral structure; alternatively, the elastic member 210 and the clamping portion 220 are separate structures.

In the embodiment, the elastic member 210 and the clamping portion 220 are selected to be in a split structure, and referring to that the clamping portion 220 is in a spherical structure, the diameter of the spherical structure is greater than the diameter of the hole opening of the mounting hole 231, so that the spherical structure can be limited in the mounting hole 231 in a rolling manner and cannot be separated from the mounting hole 231.

Alternatively, the spherical structure may be a sphere.

In this embodiment, the wall surface of the slot 110 is a concave spherical surface adapted to the spherical structure, but may be other types of surfaces capable of realizing snap-fit.

On the basis of the above embodiment, a pressing member is arranged at one end of the mounting hole 231, which is far away from the clamping portion 220, and the pressing member is detachably connected with the mounting hole 231; the elastic member 210 is disposed between the pressing member and the clamping portion 220, wherein the elastic member 210 can be conveniently and fixedly mounted by the additional pressing member.
