Detailed Description
The invention integrates a lever mechanism which moves along with a knob in four directions in a cover plate, integrates a ratchet wheel anti-loosening mechanism on an operation part, realizes the quick fastening and automatic locking of four sides of the cover plate, and realizes the purpose of quick disassembly by overcoming the resistance of a spring and reversely rotating the knob in the disassembly process, and the specific embodiment is shown in figure 1. A cover plate quick-release mechanism comprises a knob 1, a bolt 2, a first connecting rod 3, a second connecting rod 4, a third connecting rod 5, a first ratchet wheel 8, a second ratchet wheel 9, a spring 10, a bottom cover plate 6, a fixed frame 7 and an outer cover plate 11; an upright post is arranged at the center of the knob 1, the upright post penetrates through the spring 10 and the first ratchet wheel 8 and then is fixedly connected with the second ratchet wheel 9, and the first ratchet wheel 8 is fixed on the bottom cover plate 6; there are 4 pivots on the knob 1 distribution, every pivot is used for controlling the spring bolt motion of corresponding direction, in every control direction, the pivot links to each other with the one end of first connecting rod 3, the other end of first connecting rod 3 links to each other with the one end of second connecting rod 4, there is rotation center at the middle part of second connecting rod 4, this rotation center is located bottom cover plate 6, the other end of second connecting rod 4 is connected with the one end of third connecting rod 5, spring bolt 2 places in bottom cover plate 6's guide slot, can rotate and slide along with knob 1, the other end of third connecting rod 5 links to each other with spring bolt 2, through rotatory knob 1, drive spring bolt 2 and slide in guide slot activity direction, spring bolt 2 stretches out to hold and slides in the recess of inboard on fixed frame 7.
The end that the spring bolt 2 stretches out is provided with the inclined plane, can with the inclined plane contact of inboard on the fixed frame 7, when the spring bolt 2 outwards stretches out, the inclined plane on the fixed frame 7 makes the spring bolt 2 receive the pressure on perpendicular inclined plane to make the end cover board 6 receive this pressure in the opposite direction, thereby realize installing the purpose in fixed frame 7 with end cover board 6 fast.
