[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1-4 The utility model discloses a quick-connect joint for a water inlet pipe of a washing machine, comprising a joint body 1, wherein the joint body 1 comprises an inner joint 11, an outer movable sleeve of the inner joint 11 is provided with a locking sleeve 12, at least two locking buckles 13 are symmetrically and movably provided on the surface of the inner joint 11, and the locking buckle 13 is semicircular, a sealing ring 14 located above the locking buckle 13 is nested on the surface of the inner joint 11, and an inner top of the locking sleeve 12 is provided with a flared opening 18 that conflicts with the sealing ring 14. The semicircular locking buckle 13 only needs to install two symmetrical locking buckles 13 to maintain the connection stability between the inner joint 11 and the faucet, and there is no need to install multiple balls, so the processing difficulty and processing cost are greatly reduced.
[0023] Specifically, a spring 15 is movably sleeved on the surface of the inner joint 11. The arrangement of the spring 15 enables the locking sleeve 12 to have the function of automatic spring-back and reset.
[0024] Specifically, a flange 16 located at the bottom of the spring 15 is fixedly arranged on the surface of the inner joint 11. The arrangement of the flange 16 is used to support the bottom of the spring 15.
[0025] Specifically, an avoidance groove 17 which is movably sleeved with the flange 16 and the spring 15 is arranged inside the locking sleeve 12. The arrangement of the avoidance groove 17 is used to avoid the spring 15 and the flange 16. When in use, when pressing down the locking sleeve 12, the top of the inner wall of the avoidance groove 17 cooperates with the flange 16 to compress the spring 15, and at the same time, the flared opening 18 is separated from the contact with the sealing ring 14, so that the flared opening 18 faces the lock catch 13, enabling the lock catch 13 to have a space to retreat. When connecting the inner joint 11 with a faucet, the lock catch 13 retreats into the flared opening 18 due to the contact with the faucet. When the lock catch 13 contacts the concave part of the faucet, release the locking sleeve 12. The spring 15 rebounds to drive the locking sleeve 12 to rise and reset. At the same time, the flared opening 18 abuts against the lock catch 13 to be clamped with the faucet. When the flared opening 18 abuts against the sealing ring 14, at this time, the straight surface of the inner wall of the locking sleeve 12 contacts the outer side surface of the lock catch 13, making the lock catch 13 unable to retreat, ensuring the stability of the clamping between the lock catch 13 and the faucet.
[0026] Specifically, the inner side surface of the lock catch 13 is semi-circular, and the outer side surface is straight. The semi-circular inner side surface of the lock catch 13 can avoid the situation of being stuck when contacting the faucet.
[0027] Specifically, two moving holes 112 are symmetrically arranged on the surface of the inner joint 11. The two lock catches 13 are respectively movably installed inside the two moving holes 112. The moving holes 112 are used to install the lock catches 13.
[0028] Specifically, the bottom surface of the inner wall of the flared opening 18 is conical. The conical design of the bottom surface of the inner wall of the flared opening 18 facilitates the movement of abutting against the lock catch 13. At the same time, when abutting against the sealing ring 14, it can have good sealing performance and reduce the pollution of the spring 15.
[0029] Specifically, a pressing ring 19 is arranged at the bottom of the locking sleeve 12. The arrangement of the pressing ring 19 is used to provide a position for the user's finger to press down the locking sleeve 12, making it more convenient to use.
[0030] Specifically, a water pipe connecting part 111 for connecting a water pipe is arranged at the bottom of the inner joint 11. The water pipe is connected through the water pipe connecting part 111 and tightened by a clamp.
[0031] In summary, for the quick-connect joint of the washing machine water inlet pipe, compared with the joints in the form of steel balls on the market, for the semi-circular lock catches 13, only two symmetrical lock catches 13 need to be installed to maintain the connection stability between the inner joint 11 and the faucet. There is no need to install multiple balls, greatly reducing the processing difficulty and processing cost. Moreover, the process of docking with the faucet is also simpler, which meets the economic benefits and has broad application prospects.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
