[0002] At present, attachment quick connectors are used for the quick conversion of multi-purpose excavator attachments and the quick connection of oil circuits. There are as many as 60-70 types of replaceable working devices (attachments) on one model of excavator, such as grab buckets, side dump buckets, stone clamps, wood clamps, snowplows, bulldozers, breaker hammers, lifting and fork lifts, etc.

[0003] The traditional hydraulic conversion attachment quick connector adopts hydraulic design and structural design, which is mainly composed of mechanical body, locking device, hydraulic cylinder, pin and other parts; working principle: Grasping part: first buckle pin 1, extend the hydraulic cylinder, push the locking device, lock pin 2, and insert the safety pin. Disengaging part: pull out the safety pin, let the hydraulic cylinder retract (pull open the locking device), release pin 2, and then withdraw pin 1.

[0004] However, the traditional method of replacing accessories requires workers to manually insert or remove the safety pin for subsequent work, which requires special disassembly and installation tools. It takes more than 1 hour for a skilled worker to replace an operating device, which is both time-consuming and labor-intensive. Construction safety cannot be guaranteed. After the locking device is stuck with the pin shaft, it relies entirely on the safety pin for locking. The safety pin is easily damaged, resulting in damage to the secondary quick connector, which increases the difficulty of construction. Utility Model Content

[0025] The locking assembly 101 includes an articulated shaft 10 and a connecting shaft 9, both of which are fixedly connected to the interior of the special-shaped frame 6. A cylinder 12 is installed on the outer circumference of the articulated shaft 10, and an output shaft 13 is installed on the output end of the cylinder 12. The connecting shaft 9 is fixedly connected to the interior of the special-shaped frame 6. A locking jaws 14 is movably sleeved on the outer circumference of the connecting shaft 9, and one end of the output shaft 13 is movably hinged to one side of the locking jaws 14. Through the arrangement of structures such as the cylinder 12 and the safety hook 18, the pin shaft 4 is first clamped through the through groove on the special-shaped frame 6, and then the cylinder 12 is pushed hydraulically, and the cylinder 12 slides forward, and the locking jaws 14 clamps the pin shaft 2 5. At the same time, the safety hook 18 is rotated by the principle of the sliding rod 17 to more safely clamp the pin shaft 4, making it more efficient to use.

[0026] like Figure 2~Figure 3 As shown, the connecting component 20 includes a sliding rod 17 and a fixed shaft 11, the sliding rod 17 is movably hinged on one side of the locking jaws 14, the fixed shaft 11 is fixedly connected to the inside of the special-shaped frame 6, and a safety hook 18 is movably sleeved on the outer peripheral surface of the fixed shaft 11, and the other end of the sliding rod 17 is movably hinged on one side of the safety hook 18. Through the arrangement of structures such as the spring assembly 16 and the limiting shaft 15, after the device is clamped, through the arrangement of the spring assembly 16 and the limiting shaft 15, the elastic element in the spring assembly 16 is in a pop-up state during the pushing process of the locking device, which effectively controls the rebound of the locking assembly 101 and improves the safety of the connection.

[0027] like Figure 2~Figure 4 As shown, the anti-rebound component 30 includes a long axis 8 and a straight axis 7. The long axis 8 is fixedly connected to the inside of the locking jaws 14, and the straight axis 7 is fixedly connected to the inside of the special-shaped frame 6. Two symmetrically arranged limit axes 15 are fixedly sleeved on the outer circumference of the long axis 8, and a spring assembly 16 is movably sleeved on the outer circumferences of the straight axis 7 and the connecting axis 9.

At this time, the locking jaws 14 clamp the pin shaft 2 5. In the process of the locking jaws 14 being connected to the pin shaft 2 5, the hinge shaft 10 is driven to slide, so that the safety hook 18 rotates in the direction of the pin shaft 1 4, so that it clamps the pin shaft 1 4, making its clamping efficiency higher;

[0032] Furthermore, during the use of the device, through the setting of the spring assembly 16 and the limit shaft 15, when the locking device is pushed, the elastic element in the spring assembly 16 is in a pop-up state, and the elastic element prevents the spring from rebounding through the damper, thereby effectively controlling the rebound of the locking assembly 101 and improving the safety of the connection.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
