[0002] Tables are mostly made of wood, with a flat surface on top and supports underneath. People can place things on tables, do things, eat, write, work, and so on.

[0003] A search revealed that Chinese Patent Publication No. CN223111241U relates to the field of table accessories technology, and more specifically to a quick-install structure for table legs and feet. The structure includes a table leg, a foot, and a quick-install component. One end of the table leg has two shafts. The foot includes an insertion hole and two through holes. The end of the table leg with the shaft passes through the insertion hole and abuts against the table leg. The quick-install component includes a connecting plate and two fasteners. Both fasteners are slidably mounted on the connecting plate. Each fastener has an L-shaped groove with a notch at its end facing away from the connecting plate. Each fastener corresponds to a through hole, and each fastener extends into the corresponding through hole, causing the corresponding shaft to extend into the L-shaped groove. This utility model achieves quick installation of the table leg and foot by inserting the fastener into the through hole and engaging the shaft in the L-shaped groove after the table leg and foot abut against each other, offering the advantage of more convenient installation.

[0004] A search revealed that Chinese Patent Publication No. CN214617345U discloses a quick-connect structure for connecting table legs and table feet. The quick-connect structure includes a connector and a threaded end cap. The top surface of the table foot has a connecting hole. One end of the connector is fixedly connected to the table leg, and the other end passes through the connecting hole and is threadedly connected to the threaded end cap.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] refer to Figure 1 A quick-assembly structure for table leg 1, which is an important component of the table, is used to connect with and support the tabletop. The table leg 1 is integrally welded to the tabletop by a connecting block 4, and then connected to the tabletop using screw holes provided on the connecting block 4.

[0031] refer to Figure 1 and Figure 2The metal tube 3 is made of stainless steel, which has good strength and corrosion resistance. The table leg 1 includes the metal tube 3 and a protective sleeve 2 that is fitted over the metal tube 3. The protective sleeve 2 is an insulating rubber protective sleeve that can prevent the user from being injured by colliding with the metal tube 3. At the same time, it can insulate the metal tube 3 and prevent leakage of wires inside the metal tube 3. The inside of the metal tube 3 is hollow, which reduces the overall weight of the metal tube 3 and makes it easy to move.

[0032] refer to Figure 2 and Figure 3 The wire limiting groove 9 is located inside the metal tube 3. The wire limiting groove 9 is used to limit and accommodate the wire. The top of the metal tube 3 is provided with a second round hole 10 directly above the wire limiting groove 9. A connecting block 4 is fixedly connected to the top of the metal tube 3. The connecting block 4 is provided with a first round hole 5 directly above the second round hole 10. The wire is guided to the tabletop through the first round hole 5 and the second round hole 10. Then, by drilling holes in the tabletop, it can be used in multimedia classrooms that need to use computers or other electronic devices. The connecting wire can be set inside the table leg 1, and the wire does not need to be set on the outside, which strengthens the safety.

[0033] refer to Figure 2 and Figure 3 The first round hole 5 passes through the connecting block 4, which facilitates the passage of the wire. The first round hole 5 and the second round hole 10 have the same shape, making it easier and less likely for the wire to pass through the first round hole 5 and the second round hole 10. The first round hole 5 and the second round hole 10 coincide on the horizontal plane along the height direction of the table leg 1, which facilitates the positioning of the wire and makes it easier to pass through the first round hole 5 and the second round hole 10.

[0034] refer to Figure 1 The connecting block 4 is connected to the metal tube 3 by welding. Specifically, the connecting block 4 is welded and fixed to the metal tube 3 during production. The connecting block 4 is used to connect the tabletop, and the metal tube 3 is used to connect the table legs 6. The protective sleeve 2 is fixed to the metal tube 3 by applying glue, so the installation of the protective sleeve 2 is relatively convenient. It is only necessary to apply glue to the metal tube 3 in advance and then attach the protective sleeve 2.

[0035] refer to Figure 1 and Figure 4 The bottom of the table leg 1 is provided with a table foot 6, which is used to support the table leg 1 and the table board and other components. The top of the table foot 6 is provided with an embedded first groove 11, which is used to accommodate the first limiting block 12 and the second limiting block 13 and other structures. The bottom end of the metal tube 3 is inserted into the first groove 11, so that the first groove 11 can limit the metal tube 3.

[0036] refer to Figure 2The metal tube 3 has a through first limiting groove 7 on both sides of its bottom end. The first limiting groove is used to connect with the first limiting block 12, thereby further improving the stability of the metal tube 3 and the table leg 6 after connection. The metal tube 3 has a through second limiting groove 8 on the side opposite to the wire limiting groove 9 at its bottom end. The second limiting groove is used to connect with the second limiting block 13, thereby further improving the stability of the metal tube 3 and the table leg 6 after connection.

[0037] refer to Figure 2 and Figure 4 The first groove 11 has a first limiting block 12 on both sides inside. The first limiting block 12 is used to connect with the first limiting groove 7. The first limiting block 12 and the first groove 11 are movably connected. Specifically, the first limiting block 12 has a spring structure inside. When the metal tube 3 is inserted into the first groove 11, it can be pressed down to temporarily insert the first limiting block 12 into the first groove 11. When the bottom of the metal tube 3 contacts the bottom of the first groove 11, the first limiting block 12 can pop out and insert into the first limiting groove 7 to lock the metal tube 3. The two first limiting blocks 12 have a second limiting block 13 inside. The second limiting block 13 is movably connected with the first groove 11. Specifically, the second limiting block 13 has a spring structure inside. When the metal tube 3 is inserted into the first groove 11, it can be pressed down to temporarily insert the second limiting block 13 into the first groove 11. When the bottom of the metal tube 3 contacts the bottom of the first groove 11, the second limiting block 13 can pop out and insert into the second limiting groove 8 to lock the metal tube 3.

[0038] More preferably, the two first limiting blocks 12 are inserted into the two first limiting grooves 7, and the second limiting block 13 is inserted into the second limiting groove 8, with the two first limiting blocks 12 and the second limiting block 13 forming a triangular frustum shape.

[0039] refer to Figure 2 and Figure 4 The cross-sectional dimensions of the metal tube 3 are the same as those of the first limiting groove 7. The two first limiting blocks 12 are arranged opposite each other, and the two first limiting grooves 7 are arranged symmetrically with the metal tube 3 as the center. This arrangement makes it easy to position and insert the metal tube 3 into the first groove 11. Simply align the metal tube 3 and the first groove 11, and press down on the metal tube 3 to automatically engage the first limiting block 12 and the first limiting groove 7, and automatically engage the second limiting block 13 and the second limiting groove 8.

[0040] refer to Figure 5 The bottom of the table leg 6 is provided with an embedded second groove 14. The second groove 14 is used to accommodate components such as the connecting rod 15, foot pad 16 and friction ring 17, which can improve space utilization. The connecting rod 15 is fixedly connected inside the second groove 14. The connecting rod 15 is used to connect and fix the foot pad 16. The bottom end of the connecting rod 15 is fixedly connected to the foot pad 16, which is used to support the table leg 1.

[0041] refer to Figure 5 The foot pad 16 is shaped like an inverted funnel. A friction ring 17 is provided at the bottom edge of the foot pad 16. The friction ring 17 is made of rubber. The inverted funnel shape of the foot pad 16 forms a suction cup-like function. By pressing down, the air inside the foot pad 16 is expelled, creating a pressure difference between the inside and outside. The external atmospheric pressure presses the foot pad 16 firmly onto the ground, allowing the foot pad 16 to be stably fixed on the ground. The friction ring 17 at the bottom of the foot pad 16 increases the friction between the foot pad and the ground, providing strong support on the ground, reducing the likelihood of slipping, and enhancing its practicality.
