Description

Technical Field

[0001] The invention relates to the technical field of bathing chairs, and in particular to a bathing chair. Background Art

[0002] Bath chairs are used for bathing in the bathroom. They look similar to ordinary chairs and are suitable for people with limited mobility, such as the elderly, pregnant women, and the disabled. The difference between bath chairs and ordinary chairs is that bath chairs are used for bathing in the bathroom. They are designed to be more user-friendly in details according to different groups of people and their different needs. Bath chairs can not only allow them to take a bath independently, but also make bathing healthier. CN201921494693.9 discloses a commode chair, which can realize the folding of the toilet bowl frame through the folding storage piece, and realize the folding of the main frame in conjunction with the folding of the armrest frame and the support frame. The commode chair has both the function of a seat and a toilet, and can be conveniently disassembled and assembled for storage, which is easy and convenient. However, there are many problems when using it: when the commode chair is folded, the seat surface will slowly slide down under the action of gravity, resulting in the commode chair being unable to be folded for a long time, affecting the use of the bathing chair; the armrest tube of the commode chair is usually arranged parallel to the seat surface and cannot be adjusted, and the gap between the armrest tube and the support frame is often easy to clamp the user, posing a safety hazard, and the commode chair cannot be used by users with wider bodies, and the users will be clamped on both sides of the armrest tube, and the adaptability is relatively single. When the commode chair is in a folded state, the armrest tube is still in the original position, occupying a large space. Therefore, technical personnel in this field are urgently needed to design a new chair structure. Summary of the invention

[0003] The problem to be solved by the present invention is that a buckle on the connecting rod can hook the boss on the seat surface, and when no external force is applied, the two will remain in a bite state and will not loosen, thereby preventing the seat surface from slowly sliding down when subjected to gravity; when the bathing chair is in use, the anti-pinch sleeve plays the role of limiting the armrest tube, and at the same time can play an anti-pinch role, which can effectively prevent the gap between the armrest tube and the support frame from pinching the user. At the same time, when the user has a wider body, the armrest tube can be lifted so that the user will not be pinched on both sides of the armrest tube, effectively improving the overall comfort of the user, and having a wide range of applicability. When the bathing chair is in a folded state, the armrests are lifted upward, which can greatly reduce the overall space of the bathing chair, making it easy to take and put the bathing chair.

[0004] In order to solve the above problems, the present invention provides a bathing chair, including a support frame assembly, an armrest assembly, a backrest and a seat surface, wherein the seat surface force pillars are fixedly installed between the support frame assemblies, a connecting rod is sleeved on the seat surface force pillars, a swivel pin is provided at the top end of the connecting rod, the swivel pin passes through the seat surface and is axially connected with the seat surface, a seat cushion is provided on the seat surface, the armrest assembly is arranged at the upper side end of the support frame assembly, the backrest is arranged at the upper inner end of the support frame assembly, the support frame assembly includes a front frame and a rear frame, a stabilizing support portion is provided between the front frame and the rear frame of the support frame assembly, an anti-loosening and anti-gravity mechanism is provided between the connecting rod and the seat surface, and the armrest assembly is a movable and adjustable structure.

The stabilizing support part is provided in two parts, including a first stabilizing unit and a second stabilizing unit. The first stabilizing unit is an arc-shaped elastic slot block, which is fixedly provided on the top of the rear frame. One end of the front frame is provided in the arc-shaped elastic slot block so that the rear frame supports the part of the backrest supported by the front frame. The elastic pipe plug can effectively reduce the load force of the front frame on the rear frame, increase the supporting force of the front frame, and at the same time, the backrest is subjected to a stronger supporting force, so that the front frame, the rear frame, and the connecting piece form a stable triangular structure, thereby improving the stability of the bathing chair. Since the part of the front frame on which the backrest is installed is supported by the rear frame, the backrest can withstand a stronger impact force. The second stabilizing unit is a connecting piece and a connecting member. The side ends of the front frame and the rear frame are both provided with connecting pieces, and the connecting member is a pin shaft. The connecting pieces are movably connected by the connecting member. The connecting piece and the connecting member can further ensure the fixity of the front frame and the rear frame, so that the chair remains stable. The two connecting pieces can greatly reduce the size of the bathing chair after folding, and it can stand, and the stability is excellent. BRIEF DESCRIPTION OF THE DRAWINGS
