As shown in fig. 2, the insertion portion includes a first insertion portion 12 with a larger diameter and a second insertion portion 13 with a smaller diameter, and the receiving groove 11 is opened at the outer periphery of the first insertion portion 12. The second insertion portion 13 is provided with two grooves 14 arranged at intervals up and down on the periphery.
The ferrule 20 includes a flexible arc portion 21 having an opening, two ends of the opening of the arc portion 21 are both provided with a fixture block 22 protruding outwards, the arc portion 21 is sleeved in the accommodation groove 11, and the two fixture blocks 22 extend out of the accommodation groove 11.
In this embodiment, the projections of the two blocks 22 on the horizontal plane are in a shape of a Chinese character 'ba'. Alternatively, the two latches 22 may be arranged in parallel, but not limited thereto.
In this embodiment, the diameter of the arc portion 21 is larger than the diameter of the receiving groove 11 when the arc portion is not deformed, so that the arc portion 21 has a sufficient deformation length to change the distance between the two blocks 22 when the two blocks 22 are pinched.
The second pipe body 30 is provided with an inserting part 31, the inserting part 31 is provided with an inserting cavity 32 with an opening at the top end, the inserting cavity 32 is communicated with the inner cavity of the second pipe body 30, a yielding groove 33 is arranged downwards along the top end surface of the inserting cavity 32, two clamping grooves 34 are arranged on two sides of the bottom end of the yielding groove 33, and the two clamping grooves 34 are oppositely arranged and extend along the circumferential direction of the inserting cavity 32; when the insertion portion and the ferrule 20 are inserted into the insertion cavity 32 at the same time, the two latching blocks 22 are close to each other along the arc length direction of the arc portion 21, so that the two latching blocks 22 can simultaneously pass through the receding groove 33, and the two latching blocks 22 are respectively latched into the corresponding latching grooves 34 under the elastic action of the arc portion 21, so as to realize the quick connection between the first tube 10 and the second tube 30.
As shown in fig. 2, a step surface 35 is disposed in the plugging chamber 32, when the insertion portion is inserted into the plugging chamber 32, the bottom end surface of the first insertion portion 12 abuts against the step surface 35 to axially limit the insertion portion, and the top end surface of the first insertion portion 12 is flush with the top end surface of the plugging chamber 32.

In this embodiment, as shown in fig. 1, the length of the arc portion 21 extending from the fixture block 22 is greater than the thickness of the wall of the insertion cavity 32, so that not only the fixture block 22 can be prevented from being separated from the slot 34, but also the fixture block can be conveniently detached, and only the ends of the two fixture blocks 22 need to be pinched simultaneously to reduce the distance between the two fixture blocks 22 and to be lifted upwards to be separated from the abdicating slot 33, so that the first pipe body 10 and the second pipe body 30 can be separated, and the detachment is also convenient.
In this embodiment, when the arc portion 21 is not deformed, the minimum distance between the two blocks 22 is greater than the width of the receding groove 33, so as to prevent the two blocks 22 from coming off from the receding groove 33. If the minimum distance between the two blocks 22 is equal to or less than the width of the receding groove 33 when the arc portion 21 is not deformed, the two blocks 22 can be separated from the receding groove 33 without elastic deformation of the arc portion 21, and the two blocks cannot be clamped with the two clamping grooves 34.
In this embodiment, the quick connection device further includes two sealing rings 40, and the two sealing rings 40 are respectively sleeved in the two grooves 14 and are in sealing fit with the inner wall of the second tube 30.
The quick connection method of the quick connection device comprises the following steps:
firstly, the arc part 21 of the cutting sleeve 20 is sleeved in the accommodating groove 11, and the clamping block 22 extends out of the accommodating groove 11; next, the two fixture blocks 22 are close to each other along the arc length direction of the arc portion 21 to reduce the distance between the two fixture blocks 22, and at this time, the arc portion 21 is elastically deformed and tightly clasps the accommodating groove 11; then, the inserting part and the ferrule 20 are inserted into the inserting cavity 32 at the same time, and the two clamping blocks 22 move downwards along the abdicating groove 33 until moving to the bottom end of the abdicating groove 33; finally, the two clamping blocks 22 are loosened, the two clamping blocks 22 are bounced open in opposite directions under the elastic action of the arc portion 21 and are respectively clamped and matched with the two clamping grooves 34, and therefore the quick connection of the first pipe body 10 and the second pipe body 30 is completed.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
