[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0030] See also Figure 1-Figure 6 , shows a schematic diagram of the structure of a quick disassembly and assembly frame implementation of the utility model, please refer to Figure 1-Figure 6 , a quick disassembly and assembly skeleton is introduced in detail.
[0031] A quick disassembly and assembly frame includes a fixing frame 100, an assembly frame 110 with an outer diameter smaller than the fixing frame 100 is protruding from the top of the fixing frame 100, through holes 120 are symmetrically opened on the left and right side walls of the assembly frame 110, and an assembly opening 130 with an inner diameter larger than the assembly frame 110 is opened at the bottom of the fixing frame 100;
[0032] Insert blocks 200 are symmetrically slidably disposed inside the assembly frame 110. The two insert blocks 200 move simultaneously in opposite directions through a driving assembly. The insert blocks 200 are aligned with the through holes 120, and the ends of the insert blocks 200 pass through the through holes 120 through the driving assembly.
[0033] A circular plate 300 is symmetrically rotated on the inner wall of the assembly port 130, and a slot 310 is opened near one end of the two circular plates 300. The inner diameter of the slot 310 is consistent with the outer diameter of the plug block 200. The plug block 200 is a cube. The inner cavity of the fixing frame 100 is located above the assembly port 130 and has an installation cavity 320. A transverse crossbar 330 is rotatably arranged on the inner wall of the installation cavity 320. Sprockets 340 are respectively arranged on both sides of the rod body of the crossbar 330 and on the outer sides of the two circular plates 300. There are four sprockets 340 in total and they are symmetrically arranged on the left and right. The two sprockets 340 on the same side are linked by a chain 350. A second worm gear 360 is arranged in the middle of the rod body of the installation cavity 320, and a second worm 370 meshing with the second worm gear 360 is rotatably arranged in the inner cavity of the installation cavity 320.
[0034] Furthermore, the driving component includes two transverse positive and negative double-ended screws 210 rotatably arranged in the inner cavity of the assembly frame 110, and a mounting plate 260 is protruding from the side of the plug block 200 away from the through hole 120. The two sides of each mounting plate 260 are respectively penetrated by two sections of threads of the two positive and negative double-ended screws 210, and the threads of the left and right sections of the positive and negative double-ended screws 210 have opposite directions. When the two positive and negative double-ended screws 210 rotate at the same time, the two mounting plates 260 move in opposite directions, thereby driving the two plug blocks 200 to simultaneously explore the through holes 120 or simultaneously be retracted into the inner cavity of the assembly frame 110.
[0035] Furthermore, the driving assembly also includes a rotating rod 220 rotatably arranged in the inner cavity of the fixed frame 100, the rotating rod 220 is located above the middle part of the forward and reverse double-ended screw rod 210 and is arranged perpendicularly thereto, a first worm gear 230 is arranged in the middle part of the rod body of the forward and reverse double-ended screw rod 210, and a first worm 240 meshing with the first worm gear 230 is arranged on the rod body of the rotating rod 220, the front end of the rotating rod 220 extends and rotates through the front side wall of the assembly frame 110, and a first knob 250 is arranged at the front end of the rotating rod 220, and the rotating rod 220 is conveniently driven to rotate by the first knob 250, and then through the first worm gear 240 and the first worm gear 230, the two forward and reverse double-ended screw rods 210 can be driven to rotate at the same time.
[0036] Furthermore, the two sprockets 340 on the same side are in the same vertical plane, the chain 350 passes through the top of the assembly port 130, the inner side of the chain 350 is meshed with the outer teeth of the sprocket 340, and a tensioning device is provided on the inner side of the chain 350. The tensioning device is not shown in the figure and is a common device for preventing the chain 350 from loosening.
[0037] Furthermore, the lead angle of the second worm 370 is smaller than the equivalent friction angle between the teeth of the meshing second worm wheel 360, thereby achieving reverse self-locking, that is, only the second worm 370 can drive the second worm wheel 360, but the second worm wheel 360 cannot drive the second worm 370. When the cross bar 330 stops rotating, the circular plate 300 below it is relatively stable.
[0038] Furthermore, the front end of the second worm gear 370 extends and rotates through the front side wall of the fixing frame 100, and is provided with a second knob 380, which conveniently drives the second worm gear 370 to rotate, and then the cross bar 330 is rotated through the second worm wheel 360, and then the two circular plates 300 are driven to rotate by the sprocket 340 and the chain 350.
[0039] In the specific use process, the device is convenient for quickly installing a temporary skeleton without tools. During assembly, the assembly frame 110 of one fixing frame 100 is inserted into the assembly port 130 of another fixing frame 100, and the through hole 120 and the slot 310 are checked from the side gap to align the two. The first knob 250 at the bottom is turned to make the two mounting plates 260 move in opposite directions, driving the two plug blocks 200 to simultaneously protrude out of the through hole 120 and insert into the groove of the slot 310, thereby realizing the assembly of the two fixing frames 100. The angle of the two fixing frames 100 after assembly can also be adjusted, that is, the second worm 370 is driven to rotate by the second knob 380, and the cross bar 330 is rotated by the second worm wheel 360, and the two circular plates 300 are driven to rotate by the sprocket 340 and the chain 350, so that the angle of the circular plate 300 below changes. In addition, since the second worm 370 and the second worm wheel 360 can realize reverse self-locking, the multiple fixing frames 100 are relatively stable after installation.
[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
