As shown in FIG. 4 , in the part of the slider assembly 1621 including the slider 4 , there are two positioning pin holes 401 in the center of the left and right square cylinders of the slider 4 , which are used to cooperate with the positioning pins 3 in FIG. 3 . The positioning pins The top of the hole 401 is a "conical funnel type" inclined surface pin hole structure. After the positioning pin 3 touches the tapered part, the slider 4 is automatically adjusted to the position under pressure, and the matching between the pin and the hole is completed. Complete the alignment of the quick connector.

One limit pin 5 is fixed on each of the left and right sides of the slider 4 , and two limit pins 5 are fixed on each of the front and rear sides, for a total of six limit pins. A pair of lower quick joints 6 are fixed in the center of the slider 4, and a ferrule 601 is sleeved above the joints. When the docking with the upper quick joint 2 is completed, the ferrule will bounce upwards, and the ferrule can be separated after pressing the ferrule down to reset it. The two ferrules 601 are jointly fixed by the ferrule coupling sleeve 7, so that pressing the ferrule coupling sleeve 7 down can simultaneously drive the two ferrules 601 to press down. The pin 8 is inserted into the hole 403 of the ferrule connecting sleeve 7 and the hole 701 at the bottom of the slider 4, both of which are clearance fit; the top of the pin 8 is fixed from top to bottom with a nut 801, a metal washer 802, a spring 803 and a sliding The metal gasket 804 is pressed on the ferrule coupling sleeve 7 .

The slider seat 9 part of the slider assembly 1621 as shown in FIG. 5, in which the slider 4 can be placed. Six limit pin holes 901 are correspondingly formed on the front, rear, left and right sides of the slider seat 9, and the slider 4 is limited to adjust and move within a certain plane range through the cooperation of the pins and the holes. A square hole 903 is opened on the left and right sides of the bottom surface of the slider base 4 for passing the positioning pin 3 through; a square hole 904 is opened in the center of the bottom surface for passing the lower quick connector 6 therethrough. There are four holes 902 on the front and back of the slider seat, which are used for bolting to the guide rod sleeve 13 .

As shown in the guide rod assembly 1622 in Figure 6, the guide rod seat 11 is fixed on the base 10; the guide rod 12 is sleeved in the guide rod seat 11; the upper end of the guide rod is sleeved in the guide rod sleeve 13 and fixed by bolts; The block base 9 and the guide rod assembly 1622 are fixed by bolts through the guide rod sleeve 13. The function of the guide rod assembly 1622 is to support the slider base 9 to keep it in a horizontal state, and to maintain the vertical position of the slider base 9 during the lifting process. sex.

As shown in the lift cylinder assembly 1623 shown in FIG. 7, the lift cylinder 14 is fixed on the base 10, the oil inlet and outlet holes 1401 at the upper and lower ends of the cylinder are connected to the hydraulic system of the vehicle, and the lift of the cylinder is controlled by the vehicle; the hydraulic rod cap 16 is fixed on the The top of the hydraulic rod 15; the center of the hydraulic rod cap 16 has a hole, which is matched with the pin hole 906 in FIG. 5 and the ferrule 17 in FIG. 2 through the pin 18 in FIG. lift.

Figure 8 is mainly to illustrate the principle of automatic disengagement of the quick connector. The figure includes the slider assembly 1621 and the lift cylinder assembly 1623. The hydraulic rod cap 16 is connected with the vertical pin 8 with a hook-like structure through a metal ring 19, and the purpose of not directly connecting is to reduce the rigid contact during the movement.

The pin 18 and the hole of the hydraulic rod cap 16 are in clearance fit, and the space left is to pull the vertical pin 8 with the hook-like structure, and drive the metal gasket 804 to press down the ferrule coupling sleeve 7, thereby driving the two ferrules 6 Slide down to reset to disengage the two sets of quick connectors. The purpose of adding the spring 803 is to increase the tension tolerance, and also play a certain buffering role.

Because of having the above-mentioned structure, the working principle of the present invention is:

First, the driver starts the lift cylinder in the car, and the hydraulic rod lifts up against the slider seat. During the lifting process, the direction is fixed by the guide rod, so that the movement track is kept vertical.

When the slider seat is raised to a certain height, the positioning pin is in contact with the tapered hole part of the slider, and the slider automatically adjusts its position after being stressed, so that the pin and the pin hole are docked. After the docking of the pin and the pin hole is completed, the upper and lower sets of quick joints are aligned, the oil cylinder continues to rise, the quick joint can complete the jointing, and the box door can be opened for unloading.

After the unloading is completed, the box door is closed, the lifting cylinder is lowered, and at the same time, the joint disengagement mechanism is driven to press down the ferrule coupling sleeve, so that the two pairs of quick joints can be disengaged. The cylinder continues to descend back to its original position, and the work flow is completed.
