This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As shown in fig. 1 to 7, the present invention provides a joint structure capable of realizing quick connection. The joint structure comprises a first joint 1, a second joint 2 and a movable clamping piece 3 movably arranged on the first joint 1. Wherein, the one end of first connector 1 has and holds chamber 11, activity holder 3 movably allows the one end of second connector 2 stretches into hold chamber 11, and the one end of second connector 2 stretches into hold and keep behind the chamber 11 second connector 2 with the connection status of first connector 1. Further, when the first connector 1 and the second connector 2 are in a connected state, the movable clamping piece 3 movably allows one end of the second connector 2 extending into the accommodating cavity 11 to be quickly separated. As shown in fig. 2 and fig. 3, the second connector 2 can extend into the accommodating cavity 11 of the first connector 1 along the extending direction shown in the figures, and the movable clamping member 3 can hold the second connector partially extending into the accommodating cavity 11 by the cooperation of the clamping portion 32 of the movable clamping member and the clamping block 21 on the second connector, so that the second connector 2 cannot fall off from the first connector 1.

As shown in fig. 7, the movable holder 3 includes a movable holder body 31, a holding portion 32 at one end of the movable holder body 31, a fulcrum portion 31 at the middle of the movable holder body 31, and a movable portion 33 at the other end of the movable holder body 31. The movable holding member 3 is movably connected to the first connector 1 via the fulcrum portion 34, so that the holding portion 32 and the movable portion 33 can move away from or close to the first connector 1 around the fulcrum portion 34.

As shown in fig. 3 and 7, the movable portion 33 is supported by the first joint 1 through a spring 10. In the unstressed condition, the spring 10 supports the movable portion 33 away from the first joint head 1 and the clamping portion 32 close to the first joint head 1. When the movable portion 33 is subjected to a force, for example, when the movable portion 33 is pressed, the movable portion 33 is moved closer to the first connector 1, and the holding portion 32 is moved away from the first connector 1. As shown in fig. 4 and 5, an installation groove 12 is formed on the outer circumference of the first coupling head 1. The mounting groove 12 is used for accommodating and mounting the movable clamping piece 3. The movable clamp 3 can be movably connected with the periphery of the first connector 1 through the fulcrum part 34.

In another case, for example, when the second connector 2 extends into the accommodating cavity 11 of the first connector 1 along the extending direction, since the guiding portion 211 of the second connector 2 is an oblique angle, it will stretch the holding portion 32 along the extending direction, so that the holding portion 32 moves away from the first connector 1. Since the movable portion 33 is moved in the opposite direction to the holding portion 32, in this case, the holding portion 32 moved away from the first connector 1 will bring the movable portion 33 close to the first connector 1. This case is also similar to the case where the movable portion 33 is pressed.

Therefore, through the activity of the movable clamping piece 3, the second connector 2 can conveniently extend into the accommodating cavity 11 to be connected with the first connector 1, and can also conveniently separate from the first connector 1. When the second connector 2 extends into the accommodating cavity 11, in order to maintain the connection state of the second connector 2 and the first connector 1, the clamping portion 32 of the movable clamping member 3 is engaged with the clamping blocks 21 and 22 on the second connector 2. It should be understood that a plurality of latch blocks may be provided on the second connector 2, and the clamping portion 32 may be engaged with a plurality of latch blocks 21, 22 simultaneously, or may be engaged with only a single latch block 21 or 22.

The locking portion 212 can cooperate with the clamping portion 32 of the first connector 1 to maintain the connection state of the first connector 1 and the second connector 2.

Further, as shown in fig. 3 and 7, the spindle portion 34 protrudes from the inner surface 311 of the movable clamp body 31 and is formed with a spindle hole 312. The mounting groove 12 has a through hole 13 corresponding to the spindle hole 312. The fulcrum 9 movably connects the movable clamp 3 to the first connector 1 through the through hole 13 and the fulcrum hole 312. Preferably, the fulcrum part of the movable clamping piece abuts against the bottom of the mounting groove.

Preferably, two movable clamping members 3 are symmetrically disposed on the first connector 1, and the clamping blocks 21 and 22 surround one end of the second connector 2 extending into the accommodating cavity 11, so that the clamping portions 32 of the two movable clamping members 3 can both form a fit with the locking portions 212 on the clamping blocks.

Further, an end of the clamping portion 32 facing the direction in which the second connector extends into the accommodating cavity (i.e., the extending direction shown in fig. 1) has an inclined surface 321 from outside to inside along the radial direction of the accommodating cavity. The inclined surface 321 cooperates with the guiding portion 211 of the latch 21 on the second connector 2 to guide the second connector 2 to extend into the accommodating cavity 11.

The sealing ring 8 can the second connector 2 stretches into hold behind the chamber 11 with the inner wall that holds the chamber 11 forms the contact, in order to seal first connector 1 with the connection of second connector 2.

Further, as shown in fig. 1 to 3, the first to-be-connected component 6 is connected with the first connector 1 through the first sleeve 4, and the second to-be-connected component 7 is connected with the second connector 2 through the second sleeve 5. It is to be understood that the first to-be-connected member 6 and the second to-be-connected member 7 may be pipes, or other similar members. The end of the first connecting head 1 remote from the accommodating cavity 11 is provided with a first adapting structure 13 for the first part to be connected 6. And a second adaptive structure 23 of a second to-be-connected part is arranged at one end of the second connector 2 far away from the direction extending into the first connector 1. When connecting, one end of the first connecting head 1 with the first adapting structure 13 extends into the first connecting cavity of the first part to be connected 6, and the first adapting structure 13 abuts against the inner wall of the first connecting cavity, and the first sleeve 4 is sleeved at the joint of the first connecting head 1 and the first part to be connected 6, so that the first connecting part 6 is held between the first sleeve 4 and the first connecting head 1, as shown in fig. 3. Similarly, the end of the second connector 2 having the second adapting structure 14 extends into the second connecting cavity of the second connector 7, and the second adapting structure 23 abuts against the inner wall of the second connecting cavity, and the second sleeve 5 is sleeved on the second connector 2 and the second connecting part of the second connector 7, so that the second connector 7 is held between the second sleeve 5 and the second connector 2.

As shown in fig. 3, 5 and 6, the first adapting structure 13 may be a protrusion having an adapting inclined surface, and the adapting inclined surface makes the outer diameter of the protrusion gradually decrease in the direction away from the first connector 1, so that one end of the first connector 1 can be conveniently inserted into the first connecting cavity of the first to-be-connected component 6. At the same time, the adapted inclined surface is inclined to one side, so that one end of the first connection head 1 can better maintain the connection with the first connection chamber of the first part to be connected 6. The second adapting structure 23 may be a protrusion having an adapting inclined surface, and the adapting inclined surface makes the outer diameter of the protrusion decrease from large to small along the direction away from the second connector 2, so that one end of the second connector 2 can be conveniently inserted into the second connecting cavity of the second to-be-connected component 7. At the same time, the adapted inclined surface is inclined to one side, so that one end of the second connecting head 2 can better maintain the connection with the second connection cavity of the second to-be-connected component 7.
