[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1, reference Figures 1 to 4, is the first embodiment of the present invention, which provides a docking device, including a fixing mechanism 100, which includes a No. 1 arc buckle 101, and a connecting shaft 103 arranged on the No. 1 arc buckle 101, and the No. 1 arc buckle 101 is movably connected to the No. 2 arc buckle 102 through the connecting shaft 103; in this embodiment, through the setting of the connecting shaft 103, the No. 1 arc buckle 101 and the No. 2 arc buckle 102 can be opened and closed.

[0042] The first arc buckle 101 is provided with a first movable groove 101a, the first arc buckle 101 is provided with a support arm 101d, and the support arm 101d is provided with a support shaft 101e;

[0043] The second arc buckle 102 is provided with a second movable groove 102a, and the second arc buckle 102 is provided with a clamping block 102d;

[0044] The locking extrusion member 200 includes an extrusion wheel 201 rotatably arranged on the outer wall of the support shaft 101e, and an arc groove 202 arranged on the extrusion wheel 201. In the present embodiment, the opening of the No. 1 movable groove 101a and the No. 2 movable groove 102a can accommodate the extrusion wheel 201, so as to facilitate accommodating the extrusion wheel 201 after the No. 1 arc buckle 101 and the No. 2 arc buckle 102 are closed.

[0045] Specifically, the center of the arc groove 202 coincides with the axis center of the support shaft 101e. In this embodiment, the arrangement that the center of the arc groove 202 coincides with the axis center of the support shaft 101e facilitates the rotation of the extrusion wheel 201.

[0046] Furthermore, it also includes a resistance plate 400 arranged on the first arc buckle 101; the extrusion wheel 201 is eccentrically arranged on the outer wall of the support shaft 101e. In this embodiment, due to the eccentric setting, the cable can be compressed when the extrusion wheel 201 rotates.

[0047] The axis of the supporting shaft 101 e is offset from the axis of the connecting shaft 103 .

[0048] Preferably, arc grooves 202 are provided at both ends of the extrusion wheel 201, and the inner wall of the arc groove 202 is slidably connected to the outer wall of the clamping block 102d.

[0049] When in use, align the two ends of the cable and place them between the No. 1 arc buckle 101 and the No. 2 arc buckle 102, then close the No. 1 arc buckle 101 and the No. 2 arc buckle 102, align the clamping block 102d with the arc groove 202, and rotate the extrusion wheel 201. Since the extrusion wheel 201 is eccentrically arranged, the extrusion wheel 201 will squeeze the cable when rotating. Since the center of the arc groove 202 and the support shaft 101e are coaxially arranged, when the extrusion wheel 201 is rotated, the distance between the No. 1 arc buckle 101 and the No. 2 arc buckle 102 will not change, and the cable is compressed by the extrusion wheel 201 to achieve fixation.

[0050] It should be noted that, since the axis of the support shaft 101e is deviated from the axis of the connecting shaft 103 and is arranged on the side away from the contact plate 400, when the extrusion wheel 201 rotates to contact the contact plate 400, the reaction force provided by the cable pressure will push up the extrusion wheel 201, and due to the eccentric setting of the extrusion wheel 201, the extrusion wheel 201 has a tendency to rotate, and the extrusion wheel 201 contacts the contact plate 400 to limit the deflection of the extrusion wheel 201, so that the extrusion wheel 201 can be locked, and the greater the reaction force of the cable on the extrusion wheel 201, the greater the locking strength of the extrusion wheel 201, which also means that the cable is locked. The greater the fixing force, the stronger the stability of the cables after docking. However, after the extrusion wheel 201 is locked, since the clamping block 102d is located in the arc groove 202, the No. 1 arc buckle 101 and the No. 2 arc buckle 102 are squeezed by the cable and have a tendency to open. The No. 1 arc buckle 101 and the No. 2 arc buckle 102 move away from each other, which will increase the distance between the clamping block 102d and the support shaft 101e. Combined with the arc setting of the arc groove 202, the clamping block 102d can be locked, which means that at the same time, the No. 1 arc buckle 101 and the No. 2 arc buckle 102 can be locked to complete the connection and fixation of the cable.

[0051] In summary, the device can quickly connect cables, and has a good fixing effect after being fixed, is not easy to loosen, and can be reused, with high efficiency and low cost.

[0052] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, it also includes a mounting member 300. The mounting member 300 includes a support block 301 arranged at the end of the connecting shaft 103, and a mounting plate 302 arranged on the support block 301. The mounting plate 302 is provided with a fixing hole 303. In this embodiment, the mounting plate 302 is made of insulating material, and the fixing hole 303 is provided to facilitate the installation and fixation of the mounting plate 302.

[0053] Specifically, the outer wall of the No. 1 arc buckle 101 is provided with a No. 1 support plate 101b, and the No. 1 support plate 101b is provided with a No. 1 spring 101c; the outer wall of the No. 2 arc buckle 102 is provided with a No. 2 support plate 102b, and the No. 2 support plate 102b is provided with a No. 2 spring 102c. In this embodiment, multiple No. 1 springs 101c and No. 2 springs 102c are provided, and the setting of the No. 1 spring 101c and the No. 2 spring 102c facilitates the control of the closing of the No. 1 arc buckle 101 and the No. 2 arc buckle 102.

[0054] The rest of the structure is the same as that of Example 1.

[0055] When in use, due to the setting of the No. 1 spring 101c and the No. 2 spring 102c, the No. 1 arc buckle 101 and the No. 2 arc buckle 102 will have a closing movement tendency. When the cable is clamped, the extrusion wheel 201 is pushed by the cable to deflect the No. 1 arc buckle 101, and the cable is pressed between the No. 1 arc buckle 101 and the No. 2 arc buckle 102. At this time, the elastic force of the No. 1 spring 101c and the No. 2 spring 102c makes the No. 1 arc buckle 101 and the No. 2 arc buckle 102 clamped and closed, realizing preliminary limiting, which is convenient for auxiliary limiting in the process of clamping the cable.

[0056] Example 3, reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, is different from the previous embodiment in that it also includes a rotating rod 500 arranged on the extrusion wheel 201.

[0057] Specifically, the rotating rod 500 includes a threaded end 502 threadedly connected to the extrusion wheel 201, and an insulating rod 501 arranged on the threaded end 502. In this embodiment, the setting of the threaded end 502 facilitates the operator to connect the insulating rod 501 and the extrusion wheel 201.

[0058] Furthermore, the first arc buckle 101, the second arc buckle 102, the connecting shaft 103, and the extrusion wheel 201 are all made of copper. In this embodiment, the selection of copper material can enhance the conductive effect of the structure, increase the conductive area, and enhance the load capacity of the cable after docking.

[0059] The rest of the structure is the same as that of Example 2.

[0060] In the initial state, the rotating rod 500 should be on the side where the contact plate 400 is located. Since the rotating rod 500 is longer, according to the lever principle, the No. 1 arc buckle 101 can have a tendency to deflect, that is, an opening will be generated between the No. 1 arc buckle 101 and the No. 2 arc buckle 102. The opening is convenient for the operator to place the cable. The cable is placed between the No. 1 arc buckle 101 and the No. 2 arc buckle 102, and then the extrusion wheel 201 is rotated by the rotating rod 500 to align the arc groove 202 with the clamping block 102d. The No. 1 arc buckle 101 and the No. 2 arc buckle 102 are closed to clamp the cable. When the extrusion wheel 201 is rotated to fit on the contact plate 400, the connection and locking of the cable are completed. Finally, the insulating rod 501 is rotated to disassemble and separate the insulating rod 501 to complete the docking of the cable.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
