Description

Background Art

[0001] The utility model relates to the technical field of quick-insertion connectors, in particular to a connection and fixing structure for quick-insertion connectors. Technical Field

[0002] Quick-plug connectors have been widely used in various industries. The specific requirements are to achieve the connection between pipes or connectors, and to achieve the purpose of quick plugging when connecting. When quick plugging, it is necessary not only to play a sealing role, but also to achieve a certain tensile strength, so as to ensure an effective connection relationship.

[0003] The connecting and fixing locking member mentioned in the quick-connect connector assembly with application number 2024102382678 and the locking member mentioned in the quick-connect connector with dynamic and static sealing function with application number 2024204005446 will both encounter deformation during use, especially in high temperature environments, that is, the sub-buckle cannot be well docked with the mother buckle, resulting in poor locking. After deformation, the locking member is easy to fall off, thereby causing the entire quick-connect connector to disengage, resulting in poor reliability. Utility Model Content

[0004] In order to solve the reliability problem of the locking piece of the quick-insertion connector, the utility model provides a connection and fixing structure for the quick-insertion connector.

[0005] To this end, the technical solution of the utility model is a connection and fixing structure for a quick-insert connector, including a connector body, a locking female buckle hole is opened on the axial diameter of the connector body, a locking piece is also provided in the connector body, and a locking piece sub-buckle is provided on the locking piece corresponding to the locking female buckle hole. The characteristic is that: the locking female buckle hole is provided with an inclination angle α toward the connector body, and the corresponding locking piece sub-buckle is provided with an inclination angle β, and the inclination angle α and the inclination angle β form a locking relationship.

[0006] The effect is that the inclination angle 1 α and the inclination angle 2 β form a locking relationship. Since they are inclined inward, the deformation of the locking member sub-button will not affect them, thus solving the problem of locking reliability.

[0007] A further improvement is that the locking female buckle hole is a square hole.

[0008] The effect is that the square hole cooperates with the tilt angle α to form a tilted structure, at which time the locking member buckle with the tilt angle β can be firmly stuck in the square hole.

[0009] Finally, the square hole and the tilt angle α form an oblique square hole and form a self-locking relationship with the locking part buckle. As the pulling force increases, the locking force also increases. When assembled in place, you can hear a click (hearing); you can visually check whether the locking part buckle is assembled in place (eyes).

[0010] A further improvement is that a semicircular hole is provided inside the square hole; wherein the square hole and the semicircular hole are connected as a whole.

[0011] The effect is that the semicircular hole serves to locate the ejector pin and the unlocking device of the quick-connect connector, and the locking member can be unlocked by pressing the locking member buckle with a tool, which is convenient and quick. The square hole and the semicircular hole are connected as a whole to form a larger hole, which is convenient and practical.

[0012] A further improvement is that the inclination angle α and the inclination angle β are angles formed with the direction perpendicular to the axial diameter of the joint body, and the angles are between 2° and 30°.

[0013] The effect is that locking can be achieved when the angle is between 2° and 30°. Beneficial Effects

[0014] The utility model adopts a locking mother buckle hole to lock the inclination angle of the sub-buckle of the member, so as to realize the reliability of the locking member of the quick-insertion connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The locking female buckle hole is a square hole 101 .

[0028] The square hole 101 cooperates with the tilt angle α103 to form a tilted structure, at which the tilt angle β202 of the locking member buckle 201 can be firmly stuck in the square hole.

[0029] Finally, the square hole and the inclined angle α103 form an oblique square hole and form a self-locking relationship with the locking member buckle 201. As the pulling force increases, the locking force also increases. When assembled in place, you can hear a click (hearing); you can see whether the locking member buckle 201 is assembled in place (eyes).

[0030] A semicircular hole 102 is further provided inside the square hole 101 , wherein the square hole 101 and the semicircular hole 102 are connected as a whole.

[0031] The semicircular hole 102 serves to position the unlocking device. The locking member can be unlocked by pressing the locking member buckle 201 with a tool, which is convenient and quick.

[0032] The square hole 101 and the semicircular hole 102 are connected as a whole to form a larger hole, which is convenient and practical.
