[0005] The utility model discloses a quick plug-in assembled table, which comprises a supporting assembly and a table leg.

[0006] As a further improvement of the utility model, the inclination angle of the connecting part is 0~5°.

[0007] As a further improvement of the utility model, the connecting frame comprises a plurality of hollow rod-shaped connecting pieces and a supporting rod surrounding a closed frame body, the supporting rod is connected between adjacent connecting pieces, and the locking hole is arranged in the middle part of the connecting piece.

[0008] As a further improvement of the utility model, the connecting frame further comprises an L-shaped fixed connecting piece, through holes are formed in the two sides of the L-shaped fixed connecting piece, and the L-shaped fixed connecting piece is connected with the table plate through screws.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The connecting portion at the top end of the table leg is designed as a tapered structure with the outer diameter increasing from the top end to the bottom end, and the outer diameter of the connecting portion at the connecting position with the rod body is greater than the inner diameter of the locking hole, so that a progressive interference fit is formed during insertion. On the one hand, the radial compression force is generated by the size interference between the tapered connecting portion and the locking hole, so that mechanical self-locking without bolts is realized, and the connection stability is significantly improved. On the other hand, the difference in diameter between the end of the connecting portion and the locking hole forms a retreat limiting stop, preventing the table leg from being axially pulled out when bearing. Compared with the complex structure (such as the comparative document CN201720607493.4) in the prior art which needs to insert the rod member in multiple directions or additional fasteners, the present scheme only needs to be inserted vertically on one side to complete the fixation, which simplifies the installation steps, reduces the processing complexity of the connecting piece, and reduces the production cost. At the same time, the friction force generated by the interference fit can effectively resist the lateral load, solving the defect that the traditional insertion structure is easy to loosen, and realizing the dual optimization of rapid assembly and high stability.

[0019] Specific embodiment one: please refer to Figures 1-4The application discloses a quick-plug assembly table which comprises a table board 1, a connecting frame 2 and a table leg 3.

[0020] Specifically, the connecting frame 2 comprises connecting pieces 21, supporting rods 22 and fixed connecting plates 23. The connecting pieces 21 are vertical hollow rods, and a plurality of the connecting pieces 21 are arranged at the four sides of the table board 1. The middle part of each connecting piece 21 is provided with a locking hole 211 which is used for plugging the table leg 3. The supporting rods 22 are arranged at the adjacent end faces of each connecting piece 21, and four supporting rods 22 are arranged to form a closed frame. The fixed connecting plates 23 are arranged at the two sides of the inner side end of the supporting rods 22, and the fixed connecting plates 23 are L-shaped. The end faces of the L-shaped plates of the fixed connecting plates 23 are provided with through holes, so that the table board 1 and the connecting frame 2 are indirectly connected through screws.

[0021] Specifically, the table leg 3 comprises a rod body 31, a connecting part 32 and a foot pad 33. The table leg 3 is a hollow rod, and the connecting part 32 is arranged at one end of the table leg 3 and is integrally formed with the table leg 3. The foot pad 33 is arranged at the other end of the table leg 3 and is embedded in the hollow rod cavity of the table leg 3. The foot pad 33 is made of anti-skid material. The end of the connecting part 32 close to the connecting piece 21 is inwardly inclined, so that the end of the connecting part 32 close to the connecting piece 21 has an increasing outer diameter from one end to the other end. The inward inclination angle of the connecting part 32 is 0°-5°, and the outer diameter of the connecting part 32 at the connecting position with the rod body 31 is greater than the inner diameter of the locking hole 211, so that the table leg 3 is plugged into the connecting piece 21 of the connecting frame 2, and the interference fit between the connecting part 32 and the connecting piece 21 is realized.

[0022] Working principle: the quick plug-in assembly table of the utility model realizes quick installation and stable connection through the interference fit structure of the supporting assembly and the table leg. Its working principle is specifically shown as follows: when the table leg needs to be installed, the operator vertically inserts the connecting part at the top end of the table leg into the locking hole of the connecting piece in the connecting frame. Since the outer diameter of the connecting part increases by an inclination angle of 0°~5° from the top end to the bottom end, and the outer diameter of the connecting part at the connecting position with the rod body is larger than the inner diameter of the locking hole, the connecting part gradually forms an interference fit with the inner wall of the locking hole as the insertion depth increases when the connecting part is inserted into the locking hole, and finally radial extrusion stress is generated at the transition position of the rod body and the connecting part, thereby forming self-locking fixation between the table leg and the connecting piece. At the same time, the connecting frame fixes the rectangular closed frame body composed of the supporting rods in a stable position below the table plate through the cooperation of the L-shaped fixed connecting sheet and the screw, and the four supporting rods and the multiple connecting pieces jointly constitute a stable supporting frame, which effectively disperses the load on the table top. The hollow cavity at the bottom end of the table leg is embedded with the anti-skid foot pad, and the outer surface of the foot pad is flush with the end of the table leg, which not only guarantees the anti-skid performance, but also avoids the foot pad from falling off during transportation. The structure realizes quick plug-in assembly without additional fasteners through the geometric interference fit of the conical connecting part and the locking hole, and the overall rigid design of the connecting frame, and at the same time ensures the structural stability of the table body under the bearing state.
