[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-3 The utility model discloses a combined precision fluid quick connector, comprising a driven plug 1, one end of the driven plug 1 is fixedly connected with a connector 3, both side walls of the end of the driven plug 1 away from the connector 3 are provided with a card slot 2, the end of the connector 3 away from the card slot 2 is detachably connected with a pipe 4, a main plug 5 is provided on one side of the driven plug 1, the driven plug 1 is detachably plugged into the main plug 5, both sides of the main plug 5 are provided with a movable slot 6, a driven plate 7 is rotatably connected in the movable slot 6 through a torsion spring, a card plate 13 is fixedly connected to the inner wall of the driven plate 7 and the edge of the end away from the connector 3, the card plate 13 is carded in the card slot 2, and the card plate 13 and the card slot 2 are corresponding conical structures;

[0014] A sealing ring 14 is fixedly connected to the inner wall of the main plug 5, one end of the driven plug 1 is inserted into the main plug 5 and fits against one side wall of the sealing ring 14, and the end of the main plug 5 away from the connector 3 is detachably connected to the pipe 4, and the end of the pipe 4 located in the main plug 5 fits against the other side wall of the sealing ring 14.

[0015] The preferred technical solution of the present scheme is to insert the driven plug 1 into the main plug 5. As the driven plug 1 is inserted, the driven plate 7 can be pulled toward the inside of the main plug 5 through the torsion spring, so that the card plate 13 is carded in the card slot 2, so as to position the driven plug 1 and prevent the driven plug 1 from being detached from the main plug 5, thereby ensuring the stability of the connection. Efficient disassembly and assembly function can be achieved by plugging and unplugging, thereby improving the efficiency of later disassembly and assembly maintenance of the pipeline 4.

[0016] The outer wall of the main plug 5 is fixedly connected with a fixed ring 8, and a positioning column 9 is movably connected with the top side wall of the fixed ring 8. A limiting ring 10 is telescopically inserted in the fixed ring 8. A slot 12 is provided on the top side wall of one end of the limiting ring 10 located in the fixed ring 8, and one end of the positioning column 9 is inserted in the slot 12. A spring 15 is evenly fixedly connected to the side wall at one end of the inner side wall of the fixed ring 8, and one end of the spring 15 is fixedly connected to the side wall of the limiting ring 10 located in the fixed ring 8. A pressing plate 11 is fixedly connected to the inner wall of the end of the limiting ring 10 away from the spring 15, and the top side wall of the driven plate 7 is established as an inclined structure. The driven plate 7 and the pressing plate 11 have corresponding inclination directions, and the pressing plate 11 fits with the top side wall of the driven plate 7.

[0017] The preferred technical solution of the present scheme is that after the driven plug 1 is inserted into the main plug 5, the pressure on the limit ring 10 is released, and the limit ring 10 is pushed outward under the drive of the spring 15. As the limit ring 10 is pushed out, the pressing plate 11 will press the driven plate 7, so as to position the driven plate 7, ensuring that the card plate 13 is stably connected to the card slot 2, avoiding the driven plug 1 from accidentally detaching from the main plug 5, and the automatic card connection function can be realized through the established torsion spring, thereby improving the convenience of connection.

[0018] Specifically, when the utility model is used, the pipe 4 is first connected to the connector 3 and the main plug 5, and then the limiting ring 10 is pressed into the fixing ring 8, so as to separate the limiting ring 10 from the outer wall of the driven plate 7, and then the driven plug 1 is inserted into the main plug 5. As the driven plug 1 moves, the two driven plates 7 can be pushed outward, and as the driven plate 7 is pushed outward, the driven plug 1 continues to be inserted. When the slot 2 is aligned with the card plate 13, the card plate 13 is engaged with the slot 2 under the action of the torsion spring to achieve the function of connection and positioning, and then the pressing of the limiting ring 10 is released, so that the limiting ring 10 is pushed outward under the drive of the spring 15, and then the pressing plate 11 is attached to the outer wall of the driven plate 7 to achieve aligned pressing and ensure that the driven plate 7 is pressed. The plate 7 will not expand outward, and the problem of separation between the driven plug 1 and the main plug 5 is eliminated. When the limit ring 10 is pushed out, the slot 12 is aligned with the positioning column 9, and the positioning column 9 will be inserted into the corresponding slot 12 under the action of gravity, so as to realize the positioning of the limit ring 10 itself. When it is necessary to disassemble, the positioning column 9 is pulled out, and then the limit ring 10 is pressed into the fixed ring 8, so as to separate the driven plate 7 from the pressing plate 11, and then the driven plug 1 is pulled outward. Because the card plate 13 and the card slot 2 are conical structures, when the driven plug 1 is pulled outward with force, the driven plate 7 can be pushed outward, so that the card plate 13 is separated from the card slot 2, and the disassembly function is realized. The above can effectively improve the convenience and speed of disassembly and assembly.

[0019] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0020] Other parts of the present invention not described in detail belong to the prior art and will not be described here.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
