DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In this embodiment, referring to Figure 1 , including a fixed base plate 13 fixedly connected to the middle of the support frame, the fixed base plate 13 supports the support plate 2, and a lifting mechanism is also installed on the fixed base plate 13. The lifting mechanism is located at the lower end surface of the support plate 2 and is used to cooperate in adjusting the height of the support plate 2.

[0028] Reference Figure 1 and Figure 4The lifting mechanism includes a welding tube 4 fixed on the fixed base plate 13, a sleeve 5 is fixed in the welding tube 4, a screw 8 is passed through the internal thread of the sleeve 5, and a toothed retaining ring 7 is fixedly sleeved on the lower end of the screw 8. The upper end of the screw 8 in the vertical direction is fixedly connected to the lower end surface of the support plate 2. At the same time, a sealing plate 3 is fixedly provided at the lower end of the support plate 2. The screw 8 is passed through the sealing plate 3 and fixedly connected to the support plate 2, which helps to stabilize the connection of the screw 8. A fixing pin 9 is provided at the connection between the screw 8 and the toothed retaining ring 7. The fixing pin 9 is used to limit the screw 8. By rotating the toothed retaining ring 7, the screw 8 is driven to rotate, and the screw 8 moves along the vertical direction to adjust the height of the support plate 2.

[0029] In order to further lock the screw 8, in this embodiment, refer to Figure 1 The bottom of the fixed base plate 13 is fixedly connected to a lock pin seat 12, and a connecting groove is opened on the lock pin seat 12, which is arranged to be through. A lock pin 11 is slidably arranged in the connecting groove, and the sliding direction of the lock pin 11 points to the toothed retaining ring 7. A spring 10 is sleeved on the lock pin 11, and the bottom end and the open end of the connecting groove are integrally connected with an annular step. The two ends of the spring 10 are fixed on the two annular steps to facilitate the spring 10 to expand and contract along the length direction of the connecting groove. The spring 10 pushes the lock pin 11 tightly against the toothed retaining ring 7 with its own elastic force. A bolt 27 is threaded on the lock pin seat 12. When the bolt 27 is inserted into the connecting groove and tightens the lock pin, the lock pin 11 is tightly fixed, thereby strengthening the locking degree of the toothed retaining ring 7 and avoiding slipping.

[0030] In this embodiment, referring to Figure 1 and Figure 2 , the upper end surface of the support plate 2 is equipped with a lodging mechanism, on which an upper connecting plate is installed, and the lodging mechanism cooperates with the upper connecting plate to realize the cable removal action;

[0031] The upper connecting plate consists of a connecting adjustment plate 19, a connecting seat 20, an adjustment plate fixing screw 22, a plug and a plug connecting screw 21. The connecting seat 20 is installed at the end of the falling mechanism away from the support plate 2. The connecting adjustment plate 19 is installed on the connecting seat 20 through the adjustment plate fixing screw. The plug 25 is installed on the connecting adjustment plate 19 through the plug connecting screw 21. The plug 25 is connected to a socket 24 for easy docking with the upper equipment.

[0032] In this embodiment, referring to Figure 1 、 Figure 2 and Figure 3The falling mechanism includes a support rod 16 hinged on the support plate 2, and a movable rod 1 is provided at one end of the support rod 16 away from the support plate 2, and one end of the movable rod 1 away from the support rod 16 is hinged to the bottom of the connecting seat 20, and a rotating block 26 is fixedly provided on the hinge axis of the support plate 2 and the support rod 16. At the same time, a snap ring 23 is provided at the rotating axis of the support plate 2 and the support rod 16 to prevent the rotating axis of the support plate 2 and the support rod 16 from falling off; a threaded hole is provided on the support plate 2, and a vertical tooling 6 is threaded through the threaded hole, and the vertical tooling 6 is vertically installed on the support plate 2, and the vertical upward end of the vertical tooling 6 abuts against the rotating block 26, and cooperates with the rotating block 26 to drive the hinge shaft to rotate. By rotating the erecting tool 6, the erecting tool 6 moves in the vertical direction, pushing the rotating block 26 to rotate, driving the support plate 2 and the rotating axis of the support rod 16 to rotate, realizing the erection and fallback actions of the support rod 16, thereby realizing the rapid connection and disconnection of the cable.

[0033] Reference Figure 1 A sliding groove is provided at one end of the support rod 16 away from the support plate 2, and the movable rod 1 slides through the sliding groove. A positioning pin 18 is also provided at the open end of the sliding groove, which is used to limit the movable rod 1 in the sliding groove. A compression spring 17 is fixed between the bottom of the sliding groove and the bottom end of the movable rod 1 to ensure that the plug 25 and the socket 24 are always in a crimped state, ensuring that the cable plug 25 can be easily detached, thereby improving the reliability of cable removal.

[0034] Reference Figure 2 A pull ring 14 is fixed on the fixed base plate 13, and a tension spring 15 is buckled on the pull ring 14. The end of the tension spring 15 away from the fixed base plate 13 is buckled on the hinge axis of the movable rod 1 and the connecting seat 20. The tension spring 15 serves as a reset auxiliary, and strengthens the tensioning effect on the structure when the support rod 16 and the movable rod 1 are erected. When the upper equipment is launched, the support rod 16 and the movable rod 1 are quickly collapsed to achieve the removal of the cable.

[0035] The working principle of this embodiment is as follows: the erecting tool 6 is rotated to move the erecting tool 6 upward in the vertical direction, pushing the rotating block 26 to rotate clockwise, driving the support plate 2 and the rotating shaft of the support rod 16 to rotate clockwise, until the support rod 16 and the movable rod 1 are rotated to the erected state with the connecting seat 20, and the erecting tool 6 clamps and supports the rotating block 26, so that the support rod 16 and the movable rod 1 are in a vertical state, and at the same time, the toothed retaining ring 7 is rotated to rotate the screw 8, so that the support plate 2 is moved upward in the vertical direction to a position matching the cable, so that the plug 25 is docked with the plug of the upper equipment through the socket 24, and the cable is connected;

[0036] The reverse rotation of the erecting tool 6 causes the erecting tool 6 to move downward in the vertical direction, and the support rod 16 and the movable rod 1 are moved in the counterclockwise direction through the tension spring 15. The support rod 16 and the movable rod 1 quickly realize the falling action, and the socket 24 and the plug 25 quickly complete the disconnection action with the cable. The overall structure is compact, occupies a small space, has low mechanical cost, simple operation, is reusable, and has high reliability.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
