In some embodiments of the present invention, as shown in fig. 2 and 3, the outer peripheral wall of the first quick coupling 1 is provided with a mounting hole 13, the mounting hole 13 extends in a radial direction of the first quick coupling 1, and the elastic locking portion 12 includes: the snap arm 121 extends along an axial direction of the first quick connector 1, the snap arm 121 has a first end 1211 and a second end 1212 opposite to each other, the first end 1211 is rotatably connected to an outer peripheral wall of the first quick connector 1, the second end 1212 is adapted to be snapped into the locking groove 23, wherein, in an insertion direction of the first quick connector 1, the second end 1212 is located upstream of the first end 1211, the elastic member 122 is inserted into the mounting hole 13, the elastic member 122 is connected to the second end 1212, and the elastic member 122 is adapted to push the second end 1212 to move in a direction away from the first quick connector 1.
It is understood that the elastic member 122 is inserted in the mounting hole 13 since the mounting hole 13 is provided to extend in the radial direction of the first quick coupling 1. Therefore, the elastic member 122 can be elastically displaced along the radial direction of the first quick connector 1, and the elastic member 122 can be adapted to push the second end 1212 of the snap-in arm 121 to move away from the first quick connector 1, and under the pushing of the elastic member 122, the second end 1212 of the snap-in arm 121 can rotate around the first end 1211, so that the second end 1212 of the snap-in arm 121 is away from the outer peripheral wall of the first quick connector 1 and is snapped in the locking groove 23. When the first quick coupling 1 and the second quick coupling 2 are completely connected, the second end 1212 of the clamping arm 121 can be clamped in the locking groove 23 of the second quick coupling 2 to form a structure similar to a barb shape, so that the separation prevention effect is improved.

Specifically, when the first quick coupling 1 and the second quick coupling 2 start to be butted, the first quick coupling 1 starts to be inserted into the butting slot 22, along with the insertion of the first quick coupling 1, when the second end 1212 of the clamping arm 121 abuts against the inner wall of the butting slot 22, if the first quick coupling continues to move along the insertion direction, under the action of the downward pressure of the inner wall of the butting slot 22, the second end 1212 of the clamping arm 121 can rotate around the first end 1211, so that the second end 1212 is close to the outer circumferential wall of the first quick coupling 1, at this time, the elastic member 122 is compressed under the action of the clamping arm 121, when the first quick coupling 1 and the second quick coupling 2 complete the butting, the second end 1212 of the clamping arm 121 directly faces the locking slot 23, at this time, the inner wall of the butting slot 22 is separated from the second end 1212 of the clamping arm 121, the butting slot 22 no longer applies the downward pressure to the second end 1212 of the clamping arm 121, and the second end of the clamping arm 1212 faces away from the outward action of the first quick coupling 1 under the action of the elastic member 122 The direction of the peripheral wall is rotated and is blocked in the locking groove 23, so that the second end 1212 of the snap arm 121 can be locked in the locking groove 23, and the second end 1212 of the snap arm 121 is prevented from being disengaged from the locking groove 23.
It should be noted that, when the first quick connector 1 and the second quick connector 2 are not butted, the elastic member 122 is in an initial state, and the elastic member 122 is neither compressed nor stretched, and the second end 1212 of the snap arm 121 is supported by the elastic member 122 and is spaced from the outer peripheral wall of the first quick connector 1 by a distance d 1; when the first quick coupling 1 is butted with the second quick coupling 2, the maximum distance between the inner peripheral wall of the butting groove 22 and the outer peripheral wall of the first quick coupling 1 is d2, and the following conditions are met: d1 is larger than d2, and when the first quick connector 1 and the second quick connector 2 are completely mated, the elastic member 122 can be in a compressed state or in an initial state, i.e., the elastic member 122 is neither compressed nor stretched.
For example, in one example of the present invention, the number of the mounting holes 13 is plural, the plural mounting holes 13 are provided at intervals in the circumferential direction of the first quick coupling 1, the number of the elastic members 122 is plural, and the plural elastic members 122 correspond to the plural mounting holes 13 one by one. In addition, a plurality of clamping arms 121 are also provided, and the plurality of clamping arms 121 are matched with the plurality of elastic pieces 122 in a one-to-one correspondence manner.
In some embodiments of the present invention, as shown in fig. 2 and 3, one end of the elastic member 122 adjacent to the snap-in arm 121 is fixedly connected to the second end 1212. It can be understood that, by fixedly connecting the end of the elastic element 122 adjacent to the clamping arm 121 and the second end 1212 of the clamping arm 121, not only the connection strength between the elastic element 122 and the second end 1212 can be improved, but also the consistency of the displacement between the end of the elastic element 122 adjacent to the clamping arm 121 and the second end 1212 can be ensured, thereby avoiding the relative displacement between the elastic element 122 and the clamping arm 121, avoiding the problem of separation between the elastic element 122 and the clamping arm 121, and improving the reliability of the butt locking. For example, in one example of the present invention, the elastic member 122 is a spring, and one end of the spring adjacent to the snap arm 121 is welded to the second end 1212.
In some embodiments of the present invention, as shown in fig. 5 and 6, the outer peripheral wall of the first quick coupling 1 is provided with a mounting hole 13, the mounting hole 13 extends in a radial direction of the first quick coupling 1, and the elastic locking portion 12 includes: the limiting ball 123 and the elastic element 122, the limiting ball 123 is arranged in the mounting hole 13, the elastic element 122 is arranged between the bottom wall of the mounting hole 13 and the limiting ball 123 at intervals, and the elastic element 122 is suitable for pushing the limiting ball 123 to move towards the direction departing from the first quick connector 1, so that part of the limiting ball 123 is clamped in the locking groove 23.
It is understood that the elastic member 122 is inserted in the mounting hole 13 since the mounting hole 13 is provided to extend in the radial direction of the first quick coupling 1. Therefore, the elastic member 122 can be elastically displaced along the radial direction of the first quick coupling 1, and the elastic member 122 can be adapted to push the limiting ball 123 to move away from the first quick coupling 1, and under the pushing of the elastic member 122, a portion of the limiting ball 123 can protrude out of the mounting hole 13 and be clamped in the locking groove 23. The structure of the limiting ball 123 and the elastic member 122 is simple, so that the complexity of the structure of the elastic locking part 12 can be simplified, the manufacturing difficulty of the elastic locking part 12 is reduced, the production efficiency of the elastic locking part 12 is improved, and the production cost of the elastic locking part 12 is reduced.
It should be noted that the limiting ball 123 only partially protrudes out of the mounting hole 13, and not the whole limiting ball 123 protrudes out of the mounting hole 13, that is, there is a portion of the limiting ball 123 located in the mounting hole 13, and the mounting hole 13 always has a limiting effect on the limiting ball 123, so that the limiting ball 123 can only move along the radial direction of the first quick coupling 1. When the first quick coupling 1 and the second quick coupling 2 are not butted, the elastic member 122 is in an initial state, the elastic member 122 is neither compressed nor stretched, and the spacing distance d3 between the limiting ball 123 and the outer peripheral wall of the first quick coupling 1 is provided under the support of the elastic member 122; when the first quick coupling 1 is butted with the second quick coupling 2, the maximum distance between the inner peripheral wall of the butting groove 22 and the outer peripheral wall of the first quick coupling 1 is d2, and the following conditions are met: d3 is larger than d2, and when the first quick coupling 1 and the second quick coupling 2 are completely mated, the elastic member 122 is in an initial state, i.e., the elastic member 122 is neither compressed nor stretched.
Specifically, when the first quick coupling 1 and the second quick coupling 2 start to be butted, the first quick coupling 1 starts to be inserted into the butting groove 22, along with the insertion of the first quick coupling 1, when the limiting ball 123 abuts against the inner wall of the butting groove 22, if the first quick coupling 1 continues to move along the insertion direction, under the action of the downward pressure of the inner wall of the butting groove 22, the limiting ball 123 can move along the extending direction of the mounting hole 13 toward the direction close to the center of the first quick coupling 1, at this time, the elastic member 122 is compressed under the action of the limiting ball 123, when the first quick coupling 1 and the second quick coupling 2 complete the butting, the limiting ball 123 faces the locking groove 23, at this time, the inner wall of the butting groove 22 is retreated from the limiting ball 123, the butting groove 22 does not apply downward pressure to the limiting ball 123 any more, the limiting ball 123 moves toward the direction away from the first quick coupling 1 under the action of the outward force applied by the elastic member 122, until the part of the limiting ball 123 extends out of the mounting hole 13 and is clamped in the locking groove 23, so that the limiting ball 123 can be locked in the locking groove 23, and the limiting ball 123 is prevented from being separated from the locking groove 23.
For example, in one example of the present invention, the number of the mounting holes 13 is plural, the plural mounting holes 13 are provided at intervals in the circumferential direction of the first quick coupling 1, the number of the elastic members 122 is plural, and the plural elastic members 122 correspond to the plural mounting holes 13 one by one. In addition, a plurality of limiting balls 123 are also arranged, and the plurality of limiting balls 123 are matched with the plurality of elastic pieces 122 in a one-to-one correspondence manner.
In some embodiments of the present invention, the height of the limiting ball 123 extending out of the mounting hole 13 is H, the diameter of the limiting ball 123 is D, and the following requirements are satisfied: H/D is less than or equal to 0.5. It can be understood that the height of the limiting ball 123 extending out of the mounting hole 13 is less than or equal to half of the diameter of the limiting ball 123 itself, so that at least half of the limiting ball 123 can be ensured to be always located in the mounting hole 13, the limiting ball 123 can be ensured to be always located in the limiting range of the mounting hole 13, and the limiting ball 123 can be effectively prevented from being disengaged from the mounting hole 13. For example, in one example of the present invention, the ratio of the height of the check ball 123 protruding out of the mounting hole 13 to the diameter of the check ball 123 may be 0.5, 0.45, 0.4, 0.35, 0.3, or 0.25. Specifically, the height of the limiting ball 123 protruding out of the mounting hole 13 can be selected according to the diameter of the limiting ball 123 and the size of the butt joint 100.
In some embodiments of the present invention, as shown in fig. 5 and 6, one end of the elastic member 122 adjacent to the limiting ball 123 is fixedly connected to the limiting ball 123. It can be understood that, by fixedly connecting the end of the elastic element 122 adjacent to the limiting ball 123 with the limiting ball 123, not only the connection strength between the elastic element 122 and the limiting ball 123 can be improved, but also the consistency of the displacement between the end of the elastic element 122 adjacent to the clamping arm 121 and the limiting ball 123 can be ensured, so that the relative displacement between the elastic element 122 and the limiting ball 123 can be avoided, the problem of separation between the elastic element 122 and the limiting ball 123 can also be avoided, and the reliability of the butt joint locking can be improved. For example, in one example of the present invention, the elastic member 122 is a spring, and one end of the spring adjacent to the catching arm 121 is welded to the stopper ball 123.
In some embodiments of the present invention, the plurality of elastic locking portions 12 are provided, the plurality of elastic locking portions 12 are spaced apart in the circumferential direction of the first quick coupling 1, the plurality of locking grooves 23 are provided, and the plurality of locking grooves 23 are fitted to the plurality of elastic locking portions 12 in a one-to-one correspondence.
