Detailed Description
As shown in fig. 1-3, a folding frame for reducing a gap comprises a main frame 1 and an auxiliary frame 2 which are relatively rotated and folded, wherein a cavity chamber is arranged in the main frame 1, and a notch 3, an opening 4, a first mounting hole 5 and a second mounting hole 6 which are communicated with the outside are respectively arranged on the cavity wall of the cavity chamber. The cavity chamber is provided with an opening or a hole for installing other parts and moving or rotating related parts.
The mounting hole I5 is communicated with the mounting hole II 6 in the cavity chamber, the mounting hole I further comprises a driving piece 7, a locking piece 8, a linkage piece 9, a tension spring 10 and a positioning rod 11, the driving piece 7 is arranged at the opening 4, the locking piece 8 is arranged in the mounting hole I5, the positioning rod 11 and the linkage piece 9 are arranged in the mounting hole II 6, two ends of the tension spring 10 are respectively connected with the locking piece 8 and the positioning rod 11, the locking piece 8 and the driving piece 7 as well as the driving piece 7 and the linkage piece 9 are in clamping linkage, the auxiliary frame 2 is inserted into the opening 3, a blocking state and a moving state are arranged between the linkage piece 9 and the auxiliary frame 2, and when in the blocking state, the linkage piece 9 and the auxiliary frame 2 are embedded and rotated for limiting; in the active state, the link 9 is separated from the sub-frame 2. When the blocking state is switched to the active state, the driving piece 7 is pushed, so that the locking piece 8 and the linkage piece 9 are driven to move back to the side away from the auxiliary frame 2, meanwhile, the tension spring 10 stretches to have an elastic recovery trend, and the linkage piece 9 is separated from the auxiliary frame 2, so that the auxiliary frame 2 can be rotated and folded; when the active state is switched to a gear shifting connection state, the driving piece 7 is loosened to enable the locking piece 8 and the linkage piece 9 to automatically reset, and the linkage piece 9 is in spacing fit with the auxiliary frame 2.
The auxiliary frame 2 is provided with a first embedding opening 12 and a second embedding opening 13 which are arranged at intervals along the direction of a rotating path, so that the auxiliary frame 2 has a gear position for relative folding/rotating and is provided with various folding angles.
The driving piece 7 and the locking piece 8 are both provided with a first clamping part 14, the first clamping part 14 is of a wave-shaped structure, the clamping matching structure of the shape utilizes continuous curved surface contact to increase the contact area, multiple points are increased relatively to block and connect positions, and the structural stability is improved.
The driving part 7 and the linkage part 9 are both provided with a second clamping part 15, and the second clamping part 15 is of a square wave structure. Simple structure, stable in structure satisfies the design user demand.
The locking piece 8 is provided with a groove 16 for hooking the tension spring 10, the tension spring 10 is provided with a lantern ring 17 sleeved on the positioning rod 11, and the tension spring 10 is ensured to be stable in use.
The upper part of the driving part 7 is provided with a flat plate part 18, and the outer edge of the flat plate part 18 exceeds the lower part of the driving part 7, so that the driving part is convenient to push and use.
The side wall of the mounting hole II 6, which is close to the mounting hole I5, is provided with a curved arc groove 19 for mounting the positioning rod 11, so that the stability of the position of the positioning rod 11 is improved, and the position deviation in the use process or the action process is avoided.
The installation method comprises the following steps: 1. the auxiliary workpiece frame 2 is arranged in the hole position of the notch 3 of the main frame 1; 2. the tension spring 10 and the locking piece 8 are arranged in a cavity chamber of the main frame 1 together; 3. then the positioning rod 11 passes through the main frame 1 and the tension spring 10; 4. the driving piece 7 is buckled up by hand and is fixed with the buckle of the locking piece 8; 5. finally, the coupling element 9 is slid laterally into the grooves of the main frame 1 and the blocking element 8.
