[0034] The present invention will now be further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. Figures 1 to 9 Shown is a specific implementation of a quick-disassembly table frame of the present invention.

[0035] Example 1

[0036] like Figure 1 As shown, a quick disassembly table frame includes a column 1 and a footboard assembly 3 connected to the column 1, and a connecting column 2 is pre-installed at the bottom of the column 1. The footboard assembly 3 includes an upper footboard piece 31 and a lower footboard piece 32. The lower footboard piece 32 is provided with a notch, and a slidable disassembly slider 4 is arranged in the notch. A crankshaft 5 is rotatably mounted on the footboard assembly 3, and the crankshaft 5 is clamped on the disassembly slider 4. When the handle of the crankshaft 5 is rotated, the crankshaft 5 drives the disassembly slider 4 to move, and the footboard assembly 3 and the column 1 are tightened by the inclined surface of the disassembly slider 4, so that the footboard assembly 3 is stuck on the column 1, so as to achieve the fixing effect of the column 1 and the footboard assembly 3.

[0037] like Figure 2As shown, the disassembly and assembly slider 4 is provided with a sliding notch 41 and a crankshaft bayonet 42. The sliding notch 41 has a large opening at one end and a small opening at the other end; it is preferably in a gourd shape, and can also be set in a trapezoidal shape or other shapes. The edge of the sliding notch 41 also has an outwardly protruding inclined surface 43, which extends from the large opening end to the small opening end.

[0038] like Figure 3 As shown, the connecting column 2 includes a connecting cap 21, a threaded portion 22, and a connecting rod 22. The connecting column 2 can be pre-installed on the column 1 through threads. In addition, the connecting column 2 can also be installed on the column 1 through other connection methods such as riveting, bonding, and snapping. In order to achieve a better installation effect, the diameter of the connecting cap 21 of the connecting column 2 should be larger than the diameter of the small end of the sliding slot 41, and should be smaller than the diameter of the large end of the sliding slot 41. The diameter of the connecting rod 22 of the connecting column 2 is smaller than the diameter of the small end of the sliding slot 41.

[0039] like Figure 4 As shown, the crankshaft 5 has a curved portion 51 in the middle, and the axis of the curved portion 51 does not coincide with the rotation axis of the crankshaft 5. When the crankshaft 5 rotates around its own rotation axis, the curved portion 51 forms a rotation radius around the rotation axis. Preferably, in order to make the crankshaft 5 rotate more easily, a handle 52 is fixedly provided on the crankshaft 5. In order to prevent the handle 52 from loosening and then reversing in a natural state, the rotation radius of the handle 52 when rotating around the crankshaft 5 is greater than the distance between the rotation axis of the crankshaft 5 and the ground.

[0040] like Figure 5 As shown, the foot plate assembly 3 is composed of a foot plate upper piece 31 and a foot plate lower piece 32, and a mounting hole 311 is provided on the foot plate upper piece 31. The foot plate assembly 3 is formed by integrally forming the foot plate upper piece 31 and the foot plate lower piece 32 or welding or connecting them with fasteners. There is a cavity between the foot plate upper piece 31 and the foot plate lower piece 32, and the disassembly slider 42 and the crankshaft 5 can be hidden in the cavity to avoid exposure.

[0041] Combination Figure 6 and Figure 7 The working principle of the quick disassembly table frame of the present invention is as follows: the foot plate assembly 3 is installed on the column 1, the connecting column 2 passes through the mounting hole 311 and the large end of the sliding slot 41 in sequence, the crankshaft 5 is rotatably connected to the foot plate assembly 3, and the curved portion 51 is clamped in the crankshaft clamping slot 42. When the handle 52 is turned, the curved portion 51 drives the disassembly slider 4 to move toward the connecting column 2, and the inclined surface 43 fills the gap between the foot plate upper piece 31 and the connecting cap 21, thereby achieving the tightening effect of the foot plate assembly 3 and the column 1.

[0042] When the handle 52 is rotated in the reverse direction, the disassembly slider 4 can be moved away from the connecting column 2, so that the connecting cap 21 enters the large end of the sliding groove 41, so that the foot plate assembly 3 and the connecting column 2 can be disengaged.

[0043] After locking, the handle 52 cannot be rotated from the locked state to the released state due to the space limitation of the foot plate assembly 3. Therefore, the structure can be kept in the locked state continuously.

[0044] Preferably, in order to achieve a better locking effect between the foot plate assembly 3 and the column 1, a limiting boss 23 is provided on the connecting column 2, and the limiting boss 23 is located in the mounting hole 311. And the diameter of the limiting boss 23 is slightly smaller than the diameter of the mounting hole 311, so that the gap between the foot plate assembly 3 and the connecting column 2 can be effectively reduced, and the shaking amount of the column can be reduced during use.

[0045] Preferably, in order to achieve a better locking effect and prevent the disassembly and assembly slider from rotating, the number of the connecting columns 2 is 2.

[0046] Preferably, if Figure 1 As shown, the disassembling slide block 4 can be pre-installed in the foot plate assembly 3 through the guide connecting column 6 fixed on the foot plate upper plate 31. In addition, the disassembling slide block 4 is slidably connected with the guide connecting column 6 through the guide groove 44.

[0047] Preferably, the crankshaft 5 is rotatably connected to the lower plate 32 of the foot plate. To prevent the crankshaft 5 from axially separating from the lower plate 32 of the foot plate, axial limiting components are provided at both ends of the crankshaft 5. The axial limiting components are pins, retaining rings, retaining springs or nuts.

[0048] like Figure 8 As shown, the quick-disassembly table frame of the present invention includes a column 1 and a footboard assembly 3. A table can be constructed by simply fixing a tabletop on the quick-disassembly table frame. Tables using the quick-disassembly structure disclosed in the present invention are also within the protection scope of the present invention.

[0049] Example 2

[0050] like Fig. 9 As shown, a sliding notch 11' is provided on the bottom cover of the column 1', and an inclined surface protruding inward is formed on the sliding notch 11'. A disassembly slider 4' is slidably connected in the foot plate assembly 3', and a connecting column 2' is fixedly connected to the disassembly slider 4'. The connecting column 2' has a connecting cap 21' and a connecting rod 22' connected to the connecting cap 21'. The connecting cap 21' passes through the foot plate assembly 3' and the cover plate at the bottom of the column 1' in sequence, and the connecting rod 22' is slidably connected to the sliding notch 11'; the disassembly slider 4' also has a crankshaft bayonet 42', and a crankshaft 5 is rotatably installed on the foot plate assembly 3'. The middle curved portion 51 of the crankshaft 5 is clamped in the crankshaft bayonet 42'. The disassembly slider 4' is driven to move by rotating the crankshaft 5 so that the connecting cap 21' presses the inclined surface of the bottom cover of the column 1', so that the column 1' and the foot plate assembly 3' are fixedly connected.

[0051] Combination Figure 1-Figure 7A method for quickly disassembling a table frame includes the following steps: S1, install the end of the column 1 with the connecting column 2 facing upward, install the foot plate assembly 3 on the column 1, and make the connecting column 2 pass through the installation hole 311 of the upper plate 3 of the foot plate and the large end of the sliding groove 41 of the disassembly slider 4 in sequence.

[0052] S2. Turn the handle 52 to rotate the curved portion 51 of the crankshaft 5, thereby driving the disassembly and assembly slider 4 to slide along the connecting column 2 from the large end to the small end, so that the connecting cap 21 of the connecting column 2 presses the convex inclined surface 43 of the sliding groove 41, so that the column 1 and the foot plate assembly 3 are fixedly connected.

[0053] S3. Rotate the handle 52 in the opposite direction to rotate the curved portion 51 of the crankshaft 5, thereby driving the disassembly and assembly slider 4 to slide along the connecting column 2 from the small end to the large end, so that the connecting cap 21 of the connecting column 2 is separated from the protruding inclined surface 43, thereby disengaging the column 1 and the foot plate assembly 3.

[0054] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
