Wherein the seat frame 10 is a trapezoidal frame and is formed by welding aluminum alloy square tubes, the joint of the backrest is provided with a circular arc transition, a plurality of supporting ribs are arranged inside the backrest, the backrest 30 and the handrails 40 on the left side and the right side are formed by welding aluminum alloy circular tubes in a bending mode, the backrest 30 has gradually backward bending degree and accords with the human engineering principle, the backrest handrails are integrally welded with the seat frame 10, and foot rests 20 in the frame are connected with the seat frame 10 by adopting a detachable connecting structure 100.

In order to facilitate transportation and facilitate installation and disassembly, the frame is configured as a detachable connection structure, wherein fig. 1 shows a configuration position of the detachable connection structure 100, which is disposed at a connection position of the foot rest 20 and the seat frame 10, and the detachable connection structure 100 is used for realizing stable connection and quick disassembly of the foot rest 20 and the seat frame 10.

Fig. 3-9 illustrate specific configurations of the releasable attachment structure 100. The detachable connection structure 100 comprises a first connection part arranged on the seat frame 10, a second connection part arranged on the foot rest 20 and a clamping pin 70, wherein the first connection part is a protrusion 12 arranged below the frame square tube 11 of the seat frame 10, the second connection part is a groove 21 arranged at the upper end part of the foot rest 20, the protrusion 12 is suitable for being inserted into the groove 21 to realize the connection between the foot rest 20 and the seat frame 10, and the protrusion 12 and the groove 21 are arranged at all the connection parts of the foot rest and the seat frame; the engaging pin 70 is used for connecting the first connecting structure and the second connecting structure together in a repeatable assembling and disassembling mode; that is, the engagement pin 70 serves to fixedly connect and detachably remount the protrusion 12 and the groove 21 to ensure the reliability and stability of the connection.

Specifically, as shown in fig. 3, the first connecting structure disposed on the seat frame 10 includes a protrusion 12 disposed on the lower side of the seat frame square tube 11, the protrusion 12 is preferably rectangular, a first through hole 13 is radially disposed on the protrusion 12, and the first through hole 13 is a through groove in the horizontal direction. As shown in fig. 4 and 5, a second through hole 22 and a third through hole 23 are provided at a position of the groove 21 at the upper end of the square tube of the foot rest 20, the second through hole 22 and the third through hole 23 are communicated with the first through hole 13, and the engaging pin 70 can securely engage the protrusion 12 in the groove 21 through the second through hole 22, the first through hole 13 and the third through hole 23 in sequence.

As shown in fig. 6, the engaging pin 70 has the following structure: the engaging pin 70 is formed by bending a metal wire, and includes an end portion 71, an extending portion 72, a bent portion 73, and a removal assisting portion 74. Wherein the head portion 71 abuts against the outer surface of the upper end portion of the foot stand 20, the extending portion 72 is located in the first through hole 13 and the second through hole 22, and the bending portion 73 has a curved shape for engaging with the engaging portion 26 of the third through hole 23 to prevent the engaging pin 70 from being removed from the through hole.

The diameter of the wire of the engagement pin 70 is adapted to be inserted into the first through hole 22, the second through hole 13 and the third through hole 23 (see fig. 7), and can be closely fitted into the first through hole 22, the second through hole 13 and the third through hole 23 after insertion.
