Technical Field

[0001] The utility model relates to the technical field of wheelchairs, in particular to a foldable toilet wheelchair. Background Art

[0002] A commode wheelchair is a special wheelchair that is equipped with a toilet, which allows the user to use the toilet without leaving the wheelchair. This type of wheelchair is very practical for people with limited mobility or who need to sit in a wheelchair for a long time, as it greatly reduces the inconvenience of movement and transfer.

[0003] In the existing toilet wheelchairs, such as the mobile wheelchair toilet disclosed in the Chinese patent with patent application number CN202320777215.9, it includes a wheelchair body and a toilet bowl arranged on the wheelchair body. A through groove is provided in the middle of the seat cushion arranged on the wheelchair body, and connecting brackets are provided on the inner wall edges on both sides of the through groove. The connecting brackets include a connecting block connected to the wall of the through groove, a seat cushion ring block and a toilet bowl block. A seat cushion ring matching its shape is provided in the through groove.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, but the utility model is not limited to the following embodiments.

[0024] like Figures 1 to 5As shown, the present embodiment discloses a foldable toilet wheelchair, comprising a chair frame 1, armrests 2 installed on both sides of the chair frame 1, a seat cushion 3 installed on the top of the chair frame 1 and a backrest 4 installed on the rear side of the chair frame 1, a defecation hole 30 and a cover plate 31 for covering the defecation hole 30 are provided in the middle of the seat cushion 3, the defecation hole 30 is a U-shaped notch with an opening facing forward, a toilet bowl 5 is installed below the seat cushion 3 at a position corresponding to the defecation hole 30, specifically, mounting portions 51 are provided on both sides of the opening of the top of the toilet bowl 5, outer sides of the mounting portions 51 on both sides are provided with outer sliding grooves 511 extending forward and backward, the bottom of the seat cushion 3 is provided on both sides of the defecation hole 30 with guide strips 52 for installing the toilet bowl 5, the guide strips 52 on both sides are parallel to each other and arranged horizontally facing forward, and the toilet bowl 5 is provided with a foldable toilet wheelchair, comprising a seat frame 1, a seat cushion 3 and a backrest 4, wherein the seat cushion 3 is provided with a foldable toilet wheelchair ... The outer slide groove 511 slides and cooperates with the guide strips 52 on both sides to realize the forward and backward sliding function; the mounting portion 51 is also provided with a basin cover 53 for covering the opening of the toilet bowl 5, and the basin cover 53 slides and cooperates with the mounting portion 51. Specifically, the inner side of the mounting portion 51 is provided with an inner slide groove 512 along the length direction for the basin cover 53 to slide. Since the basin cover 53 is located on the mounting portion 51 after covering, it is necessary to extend a connecting portion 531 downward from the bottom of the rear end of the basin cover 53. The two ends of the connecting portion 531 extend outward to have guide columns 532 for cooperating in the inner slide groove 512. The guide columns 532 cooperate with the inner slide groove 512 to enable the basin cover 53 to slide forward and backward along the mounting portion 51. The basin cover 53 is opened when sliding forward and closed when sliding backward.

[0025] In this embodiment, in order to prevent the guide post 532 from sliding out of the inner groove 512 after the basin cover 53 slides forward, blocks 513 for limiting the guide post 532 are provided at both ends of the inner groove 512. At the same time, the thickness H of the block 513 is equal to the length L of the connecting portion 531 on the basin cover 53 extending downward, and the front end of the opening of the toilet bowl 5 is provided with a rotating opening 514 with the same height as the length L of the connecting portion 531 extending. In this way, when the guide post 532 slides forward to the end of the inner groove 512, the basin cover 53 can rotate downward around the guide post 532. After the basin cover 53 rotates downward, the connecting portion 531 abuts against the rotating opening 514, so that the basin cover 53 is suspended in the inner groove 512 through the guide post 532, thereby preventing the basin cover 53 extending out of the outside from interfering with the user.

[0026] Furthermore, when the opened basin cover 53 rotates downward, the corners on the mounting portion 51 will interfere with the basin cover 53, so the corners above the front end of the mounting portion 51 are rounded to make the toilet bowl 5 rotate downward more smoothly.

[0027] Furthermore, when the basin cover 53 is closed, the rotating opening 514 at the front end of the toilet bowl 5 cannot be completely covered, and the sealing effect is poor. Therefore, it is necessary to extend a baffle 533 with the same size as the rotating opening 514 downward from the front end of the basin cover 53. When the basin cover 53 is closed, the rotating opening 514 is completely closed by the baffle 533 to achieve a sealing effect.

[0028] In this embodiment, the cross-section of the guide strip 52 is a U-shaped structure, and the openings of the guide strips 52 on both sides are relatively inwardly arranged. The outer slide groove 511 makes the outer end of the mounting portion 51 form a U-shaped structure. The upper edge of the mounting portion 51 fits in the guide strip 52, and the lower edge of the guide strip 52 fits in the outer slide groove 511, so that there is a distance between the top surface of the mounting portion 51 and the bottom surface of the seat cushion 3, and the distance corresponds to the thickness of the basin cover 53.

[0029] In this embodiment, the top of the basin cover 53 is provided with a push groove 534 for conveniently pushing the basin cover 53 forward, and the push groove 534 is formed by setting an arc-shaped groove on the top of the basin cover 53; the front end of the toilet bowl 5 is provided with a handle 54 for conveniently pulling the toilet bowl 5 outward, and the handle 54 is formed by welding an arc-shaped sheet on the front end surface of the toilet bowl 5.

[0030] In this embodiment, the seat cushion 3 and the backrest 4 are detachably mounted on the chair frame 1. The chair frame 1 includes two groups of wheelchair frames 11 arranged opposite to each other and a folding mechanism 12 arranged between the two groups of wheelchair frames 11. The folding mechanism 12 drives the wheelchair frames 11 on both sides to come together to form a folding. The folding mechanism 12 includes two groups of folding rods 120 with the same structure and cross-hinged to each other, wherein the upper part of one of the folding rods 120 is connected to the upper part of the left wheelchair frame 11, and the lower end is connected to the lower part of the right wheelchair frame 11; the upper part of the other folding rod 120 is connected to the upper part of the right wheelchair frame 11, and the lower end is connected to the lower part of the left wheelchair frame 11, thereby forming a hand folding function. Preferably, when the seat cushion 3 is installed, the upper part of the two groups of cross-folding rods 120 is sufficient to accommodate the toilet bowl 5.

[0031] The above contents described in this specification are merely examples of the present invention. Technicians in the technical field to which the present invention belongs can make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the contents of the present invention specification or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
