[0024] Based on the same inventive concept, the present invention also provides a working method of a docking device having a clamping mechanism, comprising:

[0025] When connecting two net-sealing arms, the plug-in assembly (1) fixed to one of the net-sealing arms via the base is pushed toward the receiving component (2) fixed to the other net-sealing arm;

[0026] The convex butt joint (12) connected to the first base (10) is rotated on the first base (10) of the plug-in assembly (1), and the concave butt joint (12) connected to the second base (20) is rotated on the second base (20) of the receiving member (2) at the same time, so that the convex butt joint (12) and the concave butt joint are aligned; the plug-in assembly (1) is continuously pushed so that the convex butt joint (12) of the plug-in assembly (1) enters the conical claw of the concave butt joint of the receiving member (2) with a variable opening size, and the opening of the conical claw is reduced to achieve the docking of the two sealing arms.

[0027] When the two net-sealing arms are disconnected, the male joint (12) of the plug-in assembly (1) withdraws from the tapered claw with a variable opening size of the female joint of the receiving component (2) as the net-sealing arms shrink, and the opening of the tapered claw increases, and the net-sealing arms continue to shrink until the docking device is completely separated.

[0028] Preferably, the plug-in assembly (1) is continuously pushed so that the male joint (12) of the plug-in assembly (1) enters the tapered claw with a variable opening size of the female joint of the receiving member (2), and the tapered claw opening is reduced to achieve docking of the two sealing arms, which includes:

[0029] The tapered claw has a maximum opening under the elastic force of the spring A (16) and the spring B (17) of the concave joint;

[0030] The plug-in rod (120) of the convex joint (12) enters the position of the horizontal plate (22) of the conical claw under the rounded guide action of the conical claw B (15) of the conical claw, and continues to push and compress the spring B (17) to make the conical claw move horizontally in the direction of reducing the opening of the claw base (19) of the concave joint, and reduces the opening of the conical claw through the claw base (19), and clamps with the convex joint (12) to achieve the docking of the two sealing arms.

[0031] Preferably, the male butt joint (12) of the plug-in assembly (1) withdraws from the tapered claw with a variable opening size of the female butt joint of the receiving member (2) as the sealing arm contracts, and the tapered claw opening increases and continues to contract until the docking device is completely separated.

[0032] The plug-in rod (120) of the convex joint (12) withdraws from the horizontal plate (22) of the conical claw as the sealing arm contracts;

[0033] The pressure of the conical claw decreases, and the conical claw is horizontally displaced in the direction of increasing the opening of the claw base (19) of the concave joint under the elastic force of the spring B (17) of the concave joint. Under the elastic force of the spring A (16) of the concave joint, the opening of the conical claw becomes larger, and the sealing arm continues to shrink until the docking device is completely separated. Compared with the prior art, the beneficial effects of the present invention are:

[0034] (1) A docking device with a clamping mechanism, comprising: a plug-in assembly and a receiving member respectively connected to two network-sealing arms; the receiving member comprises a second base and a concave butt joint, the concave butt joint comprises: a conical claw with a variable opening size; the conical claw is rotatably connected to the second base, and the side wall of the conical claw is inclined toward the bottom; the receiving member is fixed to one network-sealing arm through the second base; the plug-in assembly comprises a first base and a convex butt joint, the first base is rotatably connected to the convex butt joint, and the plug-in assembly is fixed to the other network-sealing arm through the first base. The joints on both sides are hinged to the base and have three degrees of rotational freedom. The docking posture can be adjusted according to the contact conditions of the butt joints, which reduces the adjustment work of the docking arm during the docking operation, improves the fault tolerance of the docking device, and reduces the posture requirements of the network-sealing arm during docking.

[0035] (2) The opening of the conical claw before docking is large, and the convex joint is easier to insert, which reduces the position accuracy requirements of the docking devices on both sides during docking.

[0036] (3) Before docking, the elastic sleeve can keep the two pairs of joints in a horizontal posture; during the docking process, the elastic sleeve is compressed to achieve the posture adjustment function of the joints; when the docking device is disengaged, the compressed elastic sleeve rebounds, so that the convex joints return to their initial state.

[0037] (4) After the docking device is successfully docked, the conical claws clamp the convex joints, and the friction of the docking devices on both sides increases, which can prevent the two pairs of joints from separating when the crossing frame is impacted and vibrated.

[0038] (5) The present invention can be reused after the crossing frame is dismantled, and the system can be quickly and conveniently reset, thereby reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

The convex butt joint 12 can rotate along the spherical surface of the first base 10 with three degrees of freedom, and can rotate according to docking needs, thereby adjusting the docking posture.

[0049] The female joint also includes a spring A16, a spring B17, and a claw base 19. The conical claw is connected to one end of the claw base 19 via spring B17, and the other end of the claw base 19 is rotatably connected to a second base 20. Spring A16 is vertically positioned at the end where the conical claw connects to the claw base. The end of the claw base 19 where it connects to the conical claw is a conical structure that matches the structure of the conical claw, with the tapered sidewalls inclined toward the bottom. A stepped hole is provided between the conical claw and the claw base 19 and connected via spring B17. A second spherical cover 21 is fixedly connected to the second base 20 and has a spherical shape that matches the second base 20. The claw base 19 is positioned between the second base 20 and the spherical cover 21. A sleeve is defined in the second spherical cover 21, which is fitted with a second elastic sleeve 18. The female joint is horizontally inserted through the second elastic sleeve 18. The diameter of the male butt joint 12 is smaller than the opening diameter of the tapered jaws.

[0050] like Figure 2 As shown, the tapered jaws include: tapered jaws A14 and B15, which are connected by a horizontal plate 22 and a slot 23. The openings of the tapered jaws are rounded. The second base 20 is a spherical structure, and the end connecting the jaw base 19 to the second base 20 is a structure that mates with the spherical protrusion.

[0051] like Figure 3 As shown, the first base 10 is a spherical structure with a flange formed along its left side. The flange is provided with a plurality of first nail holes 111. Bolts 3 are threaded through the first nail holes 111 and are connected to the first spherical base 10, thereby connecting the first spherical cover 11 to the first base 10. One end of the male connector 12 is a structure that mates with the spherical protrusion, and the other end is a plug-in rod 120. The first spherical cover 11 is provided on the first base 10 and is fixedly connected to the first base 10. The first spherical cover 11 is spherically shaped to mate with the first base 10. The structure that mates with the spherical protrusion of the male connector 12 is an arcuate plate 121, which is located between the base and the spherical cover. The first spherical cover 11 is provided with a sleeve, and the sleeve is provided with a first elastic sleeve 13. The male connector 12 is horizontally inserted into the first elastic sleeve 13.

[0052] Example 2:

[0053] like Figure 4As shown, the present invention provides a docking device with a clamping mechanism, comprising two opposing frames 4, a net-sealing arm 5, a drive device 6 fixedly mounted on the frames 4, and the docking device with a clamping mechanism provided in Example 1.

Multiple rigid net-sealing bars 7 are connected to the bottom of the net-sealing arms 5 for protection.

[0054] like Figure 5 As shown, the plug assembly 1 and the receiving assembly 2 are respectively fixedly connected to the sealing arms 5 on both sides. The sealing arms 5 slide relative to each other, so that the plug assembly 1 and the receiving assembly 2 complete the docking action, and the two side frames 4 are docked. The docking device that can automatically adjust the docking posture realizes automatic correction of the docking posture, reduces the docking posture accuracy requirement, and improves docking efficiency.

[0055] When the docking device is removed, the plug-in component 1 and the receiving component 2 slide opposite to each other as the sealing arm 5 contracts, and the plug-in component 1 is separated from the receiving component 2 and can be reused after the crossing frame is removed. The system is quickly and conveniently reset, reducing the cost of use.

[0056] Example 3:

[0057] Based on the same inventive concept, the present invention also provides a working method of a docking device with a clamping mechanism, such as Figure 6 Shown, including:

[0058] Step 1: When connecting two net-sealing arms, push the plug-in component 1 fixed on one of the net-sealing arms through the base toward the receiving component 2 fixed on the other net-sealing arm;

[0059] Step 2: Rotate the male butt joint 12 connected to the first base 10 on the first base 10 of the plug assembly 1, and simultaneously rotate the female butt joint connected to the second base 20 on the second base 20 of the socket 2, so that the male butt joint 12 and the female butt joint are aligned;

[0060] Step 3: The plug-in rod 120 of the convex joint 12 enters the horizontal plate 22 of the conical claw under the rounded guide action of the conical claw B15 of the conical claw, and continues to push the compression spring B17 to make the conical claw move horizontally in the direction of reducing the opening of the claw base 19 of the concave joint. The opening of the conical claw is reduced through the claw base 19, and the convex joint 12 is clamped to achieve the docking of the two sealing arms;

[0061] Step 4: When the two net sealing arms are disconnected, the connecting rod 120 of the convex joint 12 withdraws from the horizontal plate 22 of the conical claw as the net sealing arm contracts; the pressure of the conical claw decreases, and the conical claw is horizontally displaced in the direction of increasing the opening of the claw base 19 of the concave joint under the elastic force of the spring B17 of the concave joint. Under the elastic force of the spring A16 of the concave joint, the opening of the conical claw becomes larger, and the net sealing arm continues to contract until the docking device is completely separated.
