[0021] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1 and 2 As shown, a quick-release structure of the leg tube is arranged at the four corners of the table frame 8, which can quickly fix the leg tube 9 to the table frame 8. The quick-release structure includes a leg tube mounting seat 1 and a locking member 2. Among them, the leg tube mounting seat 1 is fixed at the corner of the table frame 8. The leg tube mounting seat 1 is formed by bending a plate, and a first mounting groove 3 that matches the leg tube 9 is formed at the bottom. The leg tube 9 is inserted into the first mounting groove 3. Locking grooves are provided on both side walls of the leg tube mounting seat 1. Connecting shaft members 7 that match the locking grooves are fixed on both sides of the leg tube 9. The connecting shaft member 7 is inserted into the locking groove, and the leg tube 9 can be locked or unlocked by rotating the connecting shaft member 7.

[0024] like Figure 2 and 3 As shown, the locking slot includes a second mounting slot 5 and a stop slot 6, which are connected in sequence. The outer end of the second mounting slot 5 is open, and its length is inclined, that is, it forms an angle with the line passing through the midpoint of the stop slot 6. A connecting shaft 7 is fixed to the side wall of the leg tube 9, which mates with the second mounting slot 5. The length of the connecting shaft 7 is parallel to the length of the leg tube 9.

[0025] The locking member 2 is rotatably connected to one side of the leg tube mounting base 1. A fastening member 4 that cooperates with the locking member 2 is provided on the leg tube 9. During assembly, the leg tube 9 is plugged into the side of the leg tube mounting base 1 in an inclined shape. The connecting shaft 7 on the leg tube 9 is inserted from the notch of the second mounting groove 5 until it enters the limiting groove 6. By rotating the leg tube 9, the connecting shaft 7 on the leg tube 9 rotates synchronously under the drive of the leg tube 9, so that the connecting shaft 7 deviates from the second mounting groove 5, completing the pre-installation of the leg tube 9. The staff drives the locking member 2 downward to cooperate with the leg tube mounting base 1 to limit the position of the leg tube 9 in the vertical direction.

[0026] like Figure 2 As shown, the locking member 2 is formed by bending a plate and is divided into a limiting section 2-1 and a driving section 2-2. The limiting section 2-1 has a right-angled cross-section and a limiting surface on its outer end that mates with the fastener 4. During assembly, the user presses down on the locking member 2, causing the limiting surface on the locking member 2 to contact the bottom of the fastener 4, locking the position of the leg 9 and the fastener 4, thereby completing the installation and fixation of the leg 9. Furthermore, the outer surface of the fastener 4 is curved.

[0027] Furthermore, arc-shaped guide surfaces are provided at the top and bottom ends of the connecting shaft 7 to facilitate the connecting shaft 7 to be inserted into the second installation groove 5 .

[0028] like Figure 3As shown, the inner wall of the limiting groove 6 is provided with an arcuate surface 6-1 and a limiting flat surface 6-2 that mate with the connecting shaft 7. The arcuate surface 6-1 is aligned with the notch of the second mounting groove 5. When the connecting shaft 7 enters the limiting groove 6 from the second mounting groove 5, its end abuts against the arcuate surface 6-1. When the user rotates the leg 9, the limiting flat surface 6-2 in the limiting groove 6 defines the extreme rotational position of the connecting shaft 7, thereby defining the extreme rotational position of the leg 9.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
