In addition, in order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The detailed description and technical contents of the present invention are described below with reference to the drawings, however, the drawings are provided for reference and illustration only and are not intended to limit the present invention; the foregoing and other technical and other features, aspects, and advantages of the present invention will become more apparent from the following detailed description of the embodiments when taken in conjunction with the accompanying drawings, wherein: "upper", "lower", "left", "right", "front", "rear", etc., refer only to the orientation of the appended figures. Accordingly, the directional terminology used is intended to be in the nature of words of description rather than of limitation; further, in the following embodiments, the same or similar components will be denoted by the same or similar component numerals.

Referring to fig. 1 to 7, the improved structure of the ladder chair of the present invention comprises: a ladder chair body 10, the ladder chair body 10 mainly comprises a seat assembly 20 and a crawler belt assembly 30;

the seat assembly 20 is mainly provided with a seating area 21, a pedal 22 and a pair of seat front wheels 23 are arranged at the lower end of the front part of the seating area 21, the seat assembly 20 is provided with a connecting part 24 at the left side and the right side respectively, a pair of connecting seats 31 are arranged at the center of the front part of the track assembly 30, after the connecting parts 24 are inserted, the connecting seats 31 can be matched with a locking part 32 to penetrate and be locked, so that the seat assembly 20 and the track assembly 30 can be fixed and detached for folding;

the track assembly 30 further includes: a telescopic rod 33, a motor component 34, a control box 35, a front handle 36 and a rear handle 36, wherein the telescopic rod 33 is disposed above the track assembly 30, and can be extended to be conveniently held and controlled by a caregiver, the motor component 34 is loaded below the track assembly 30, the control box 35 is disposed at the center of the telescopic rod 33, and is mainly electrically connected to the motor component 34 for control, and the front handle 36 is disposed at the front side of the track assembly 30, and the rear handle 37 is disposed at the rear side of the track assembly 30, so that the caregiver can conveniently move and ride the ladder chair body 10.

Referring to fig. 2, the connection seat 31 and the connection portion 24 are matched with the locking member 32 to form a through-locking connection structure, wherein the locking member 32 is also applied to the rear seat wheel 27 disposed below the track assembly 30 as shown in fig. 6, the rear seat wheel 27 is designed to match the front seat wheel 23 for stable transportation of passengers, the rear seat wheel 27 is further provided with a through hole for the locking member 32 to pass through the seat assembly 20, a welded nut is disposed outside the through hole, the locking member 32 can pass through the rear seat wheel 27 and the seat assembly 20 for locking without using additional tools, the structure of the portion is simple, and the manufacturing and manufacturing workers in the field can clearly understand and therefore will not be described in any additional detail.

As shown in fig. 3, the pedal 22 further includes: a protective frame 221 is made of steel pipe, the inner side of the protective frame 221 is matched with the side edge of a placing piece 222, and the protective frame is locked by a screw 223, so that the central position of the placing piece 222 can be lower than the protective frame 221, thereby limiting the lower limbs of a rider to the inner side of the pedal plate 22 and further preventing the lower limbs of the rider from being rubbed and injured with the ground. Since the side edge of the placement member 222 is formed by an inclined surface and a flat surface after rotating in the direction of fig. 3, the placement member 222 will have a groove design when being mounted on the protection frame 221.

As shown in fig. 4, an auxiliary rod 25 is disposed at the lower center of the seating area 21 to strengthen the structural strength of the seat assembly 20, so that the seat assembly can resist external impact and stabilize the structural shape of the existing seat assembly 20, and an auxiliary wheel 26 is disposed on the auxiliary rod 25, which mainly cooperates with the track assembly 30 to form a shorter track, so that the ladder chair body 10 can be used in a narrow space;

the shorter wheel track means that, originally, when the stair chair body 10 is mainly transported on a flat ground, the connection point with the ground is the front seat wheel 23 and the rear seat wheel 27, which total 4 contact points, but when a passenger is transported in a residential stair or a narrow space, if the rear seat wheel 27 is taken as a supporting point mainly contacting the ground, when the stair chair rotates, the front seat wheel 23 is easily suspended above each step of the stair, so that a caregiver generates a great psychological pressure, because the front seat wheel 23 is suspended, the center of gravity of the chair body is deviated to the part of the stair chair body 10 close to the crawler assembly 27, the caregiver needs to apply a more careful force to perform the rotation and adjustment actions, and if the caregiver is less powerful, the chair body may dare not to rotate alone because the front seat wheel 23 is suspended; the track of the auxiliary wheel 26 and the rear seat wheel 27 is closer than the track of the front seat wheel 23 and the rear seat wheel 27, so the auxiliary wheel 26 is provided to replace the support of the front seat wheel 23 and the ground, if the suspended rotation and adjustment are required in the residential stairway or the narrow space, when the front seat wheel 23 is not yet in contact with the ground, the track of the auxiliary wheel 26 and the rear seat wheel 27 is closer, the auxiliary wheel 26 can replace the front seat wheel 23 to be in contact with the ground, and the rear seat wheel 27 is matched to form three points to support the ladder chair body 10, so that the caretaker can feel relieved to perform the rotation and adjustment.

As shown in fig. 5, the motor assembly 34 is mounted under the track assembly 30, and the motor assembly 34 can be disassembled and replaced; as shown in fig. 7, since the ladder chair body 10 is composed of the seat assembly 20 and the track assembly 30, if the ladder chair body is directly placed in a general automobile, the ladder chair body may not be placed and may not be safely fixed; therefore, the ladder chair body 10 is about 30 kilograms or more, the weight of the ladder chair can be reduced by about half after the seat assembly 20 is detached and folded, and for a common small-sized automobile or a recreational vehicle, the ladder chair can be separately placed in the space in the vehicle for storage, so that the ladder chair is more convenient to store, and the ladder chair can be assembled without additional tools.

To sum up, the utility model discloses can reduce the wheel base through setting up auxiliary wheel 26, let cat ladder chair body 10 outside the action of carrying out unsettled gyration and adjustment that can be more dexterous in stair or narrow and small space, more can be through detachable structure of folding up, let general car also can conveniently accomodate transport outward, when carrying out the reduction equipment, also need not extra instrument just can bare-handed go on.
