DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1 and 2As shown, the footstool of the utility model includes a stool surface 2 and stool legs 1 detachably mounted on the stool surface 2, the stool legs 1 include a group of support frames 3 arranged relatively parallel, a group of connecting rods 4-1 for connecting the support frames 3 to strengthen the supporting strength of the stool legs 1 are installed between the support frames 3, the connecting rods 4-1 are strip profiles, preferably hollow tubes with a square cross-section, the profiles are easy to purchase and process, and the production cost is greatly reduced.

[0022] The surfaces of the two ends of the connecting rod 4-1 are in contact with the outer surface of the support frame 3 and are provided with a first connecting piece for fixing the connecting rod 4-1 and the support frame 3. A limiting assembly that is plugged in and matched with each other is also provided between the ends of the connecting rod 4-1 and the support frame 3 to limit the movement of the connecting rod 4-1. In the utility model, if Figure 2 As shown, the first connecting member is a threaded hole 5 opened at the end of the connecting rod 4-1 and a locking bolt 6 passing through the support frame 3 and threadedly connected to the threaded hole 5. The locking bolt 6 passes through the support frame 3 from the side away from the connecting rod 4-1 and is connected to the threaded hole 5 through a thread. Both ends of the connecting rod 4-1 are fixed to the corresponding support frame 3 by the above method, so that the connecting rod 4-1 is installed between the support frames 3; specifically, refer to the attached Figure 4 As shown, the connecting rod 4-1 is a hollow tubular structure, and connecting pieces 11 are provided on the inner sides of both ends of the connecting rod 4-1, and the threaded hole 5 is opened at the center position of the inner side of the connecting piece 11. Welding feet 12 are provided around the connecting piece 11, which are bent toward the inner wall of the connecting rod 4-1 and fit with the inner wall of the connecting rod 4-1. When processing the connecting rod 4-1, the connecting piece 11 is welded to the hollow tubular connecting rod 4-1 through the welding feet 12. The welding part is set away from the threaded hole 5 to avoid deformation of the threaded hole caused by welding. At the same time, the contact area of ​​the welding part is increased, so that the welding of the connecting piece 11 is more firm.

[0023] like Figure 3 and 4 As shown, the limiting component includes a socket 7 opened on the side of the support frame 3 close to the connecting rod 4-1, a pin 8 protruding from the connecting rod 4-1 and arranged corresponding to the socket 7, the pin 8 is preferably a polygonal shape, and the pin 8 is a rectangular structure arranged on the end face of the protruding square tube. Before the connecting rod 4-1 is installed through the locking bolt 6, the pin on the connecting rod 4-1 is first inserted into the socket 7 on the supporting rod 4-1, so that after the locking bolt 6 fixes and locks the connecting rod 4-1, the connecting rod 4-1 cannot rotate under the action of external force, and the movement of the connecting rod 4-1 after installation and fixation is avoided by the limiting component, thereby avoiding the situation where the locking bolt 6 is disengaged or loosened due to the rotation of the connecting rod 4-1, thereby making the installation of the footstool more stable.

[0024] Similarly, the limiting component can also be a screw hole and locking bolt structure that is the same as the first connecting member, that is, two threaded holes are opened on the connecting plate 11 of the connecting rod 4-1, and then the connecting rod 4-1 is locked and fixed by two locking bolts, which can also achieve the above-mentioned function of preventing the connecting rod 4-1 from rotating.

[0025] Preferably, if Figure 1 and 2 As shown, in order to enhance the stability of the footstool, two pairs of reinforcing rods 4 are provided between the support frames 3, which are respectively located on the upper and lower sides of the connecting rod 4-1. The end surface of the reinforcing rod 4 is in contact with the surface between the support frames 3 and a second connecting piece for fixed connection is provided. The structure of the second connecting piece can be arranged in the same way as the structure of the first connecting piece. In order to avoid the rotation of the reinforcing rod 4, a limit assembly can also be provided at the end of the reinforcing rod 4, or a first limit surface in contact with the stool surface 2 is provided at the upper end of the upper reinforcing rod 4, and a second limit surface in contact with the ground is provided at the lower end of the lower reinforcing rod 4. In this embodiment, the reinforcing rod 4 is restricted in rotation by a limit surface, and the reinforcing rod 4 is also a square tube structure. During installation, one of the outer surfaces of the square tube is the above-mentioned limit surface, and the outer surface of the square tube is limited to the stool surface or the ground to prevent the reinforcing rod 4 from rotating, thereby preventing the reinforcing rod 4 from loosening and falling out.

[0026] like Figure 2 As shown, the support frame 3 includes a pair of vertical rods 3-1 for connecting the connecting rods 4-1 and a plurality of cross rods 3-2 welded between the vertical rods 3-1 in sequence from top to bottom. In order to realize the detachable and quick installation of the stool surface, the upper reinforcing rod 4 is detachably connected to the stool surface 2; specifically, a first through hole 9 is provided on the upper reinforcing rod 4, which passes through the upper and lower sides of the reinforcing rod 4, and a first fixing bolt 10 is provided on the upper reinforcing rod 4, which passes through the first through hole 9 from bottom to top and is threadedly connected to the stool surface 2; similarly, the upper cross rod 3-2 is also detachably connected to the stool surface 2; specifically, the upper cross rod 3-2 is arranged in contact with the stool surface 2, and a second through hole 13 is provided on the upper cross rod 3-2, and a second fixing bolt 14 is also provided on the upper cross rod 3-2, which passes through the second through hole 13 from bottom to top and is threadedly connected to the lower end of the stool surface 2.
