Description

Technical Field

[0001] The utility model belongs to the field of wheelchairs, and in particular relates to a wheelchair with a limiting function. Background Art

[0002] Nowadays, many people have difficulty in moving due to illness or accidents and need other means of transportation. Wheelchairs are simple in structure and easy to use, so they are the best choice. However, wheelchairs still have certain defects. For example, when a patient sits in a wheelchair and travels on a bad road, there are no safety measures and it is easy for him to fall off the wheelchair.

[0003] The Chinese patent with publication number CN213250509U discloses a wheelchair with a limiting function, including a wheelchair body, a first flap is rotatably connected to the right armrest of the wheelchair body, a first latch parent body is fixed to the right surface of the first flap, a first latch child body fixed to the wheelchair body is arranged at the lower side of the first latch parent body, a second latch child body fixed to the first flap is arranged at the front side of the first latch parent body, a second flap is rotatably connected to the left armrest of the wheelchair body, and a second latch parent body is fixed to the left surface of the second flap. A third latch sub-body fixed on the wheelchair body is arranged at the lower side of the second latch mother body, and a fourth latch sub-body fixed on the second flap is arranged at the rear side of the second latch mother body, which prevents the patient from falling off the wheelchair, solves the inconvenience of the patient when eating or reading and writing, and makes the placement of small objects and holding an umbrella more convenient, thereby avoiding the shortcomings of currently available products on the market. The wheelchair with a limiting function in this application has a fixed flap on the wheelchair. For some thin people, the distance between the flap and the wheelchair is too far, which affects the user's use.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0010] Optionally, an L-shaped slot hole corresponding to the limit pin is provided on one side of the armrest, and the limit pin is an L-shaped plate structure. The limit pin slides in the L-shaped slot hole, and a guide slope is provided on one side of the limit pin, and the limit pin corresponds to the limit slot, so that the limit pin can be elastically inserted into the limit slot, which facilitates quick positioning of the storage box and storage of items through the storage box.

[0011] Optionally, two T-shaped grooves are provided on the upper side of the outer flange, and two T-shaped blocks are provided at the bottom end of the cover plate. The T-shaped blocks are slidably fitted in the T-shaped grooves, and a spring ball is embedded in the bottom end of the T-shaped blocks. A positioning groove is provided at the bottom end of the inner wall of the T-shaped groove, and a plug is provided at the side opening of the T-shaped groove. A back plate is provided on the upper side of the seat plate, and four wheeled support legs are provided at the bottom end of the seat plate, which is convenient for the T-shaped blocks to slide in the T-shaped groove, thereby improving the sliding stability of the cover plate and facilitating the sliding of the T-shaped blocks, so that the spring ball is elastically stuck in the positioning groove.

DETAILED DESCRIPTION

[0023] The utility model will now be described in further detail with reference to the accompanying drawings.

[0024] See also Figure 1-4 As shown, in the present embodiment, a wheelchair with a limiting function is provided, comprising a seat plate 1, two armrests 2 are fixed on the upper side of the seat plate 1, a storage box 3 is horizontally rotatably fitted on the upper side of one armrest 2, a limiting pin 4 corresponding to the storage box 3 is elastically slidably fitted on the other armrest 2, a cover plate 5 is horizontally slidably fitted on the upper side of the storage box 3, a table plate 6 is slidably fitted on the upper side of the cover plate 5, and a positioning handle bolt 7 is threadedly fitted on the table plate 6.

[0025] By rotating the storage box 3, the storage box 3 is rotated to between the two armrests 2, and the storage box 3 is quickly positioned by the limit pin 4, so that items can be stored in the storage box 3. At the same time, the storage box 3 can prevent the user from falling out of the wheelchair. By sliding the cover plate 5, the storage box 3 can be quickly opened to facilitate the quick placement of items. The positioning handle bolt 7 is rotated to release the limit of the table top 6 on the cover plate 5, so that the distance between the table top 6 and the user can be adjusted, so that users of different body shapes can use the table top 6.

[0026] In this embodiment, two first T-shaped grooves 500 are provided on the upper side of the cover plate 5, and two T-shaped protrusions 601 are provided at the bottom end of the table top 6, and the T-shaped protrusions 601 are slidably fitted in the first T-shaped grooves 500. By sliding the T-shaped protrusions 601 in the first T-shaped grooves 500, the stability of the table top 6 sliding on the cover plate 5 is improved, and the sliding of the table top 6 is facilitated.

[0027] In this embodiment, there is a distance between the side surface of the storage box 3 and the inner side of the armrest 2. Two outer flanges 301 are provided on the upper end of the storage box 3, and the storage box 3 is rotatably fitted on the armrest 2 through the outer flanges 301. A limiting groove 302 is provided at the bottom end of the other outer flange 301, which is convenient for elastically inserting the limiting pin 4 into the limiting groove 302, so as to quickly position the storage box 3 and store items through the storage box 3. At the same time, the storage box 3 can reduce the chance of the user falling out of the wheelchair.

[0028] An L-shaped slot 201 corresponding to the limit pin 4 is provided on one side of the armrest 2 of the present embodiment. The limit pin 4 is an L-shaped plate structure. The limit pin 4 slides in the L-shaped slot 201. A guiding slope is provided on one side of the limit pin 4. A spring is provided between the limit pin 4 and the inner wall of the L-shaped slot 201, and the limit pin 4 corresponds to the limit slot 302, so that the limit pin 4 can be elastically inserted into the limit slot 302, which is convenient for quickly positioning the storage box 3 and storing items through the storage box 3. At the same time, the storage box 3 can reduce the chance of the user falling out of the wheelchair.

[0029] The upper side of the outer flange 301 of the present embodiment is provided with two T-shaped slide grooves 303, and the bottom end of the cover plate 5 is provided with two T-shaped blocks 501.

The bottom end of the inner wall of the T-shaped slide groove 303 is provided with a positioning groove 304. A plug 305 is provided at the side opening of the T-shaped slide groove 303. A backing plate 101 is provided on the upper side of the seat plate 1, and four wheel support legs 102 are provided at the bottom end of the seat plate 1, which are convenient for sliding fit in the T-shaped slide groove 303 through the T-shaped blocks 501, thereby improving the sliding stability of the cover plate 5, facilitating the sliding of the T-shaped blocks 501, and making the spring beads 502 elastically snap into the positioning grooves 304, so as to facilitate positioning the cover plate 5 in a shielding state against the storage box 3.

[0030] Working principle: Rotate the storage box 3 to rotate it between the two armrests 2, and elastically insert the limit pin 4 into the limit groove 302 to facilitate quick positioning of the storage box 3, so as to facilitate storing items through the storage box 3. At the same time, the storage box 3 can prevent the user from falling out of the wheelchair. The storage box 3 can be quickly opened by sliding the cover plate 5 to facilitate quick placement of items. The storage box 3 is covered by the sliding cover plate 5 to drive the T-shaped block 501 to slide, so that the spring contact bead 502 is elastically stuck in the positioning groove 304, so as to facilitate the covering state of the positioning cover plate 5 on the storage box 3. Rotate the positioning handle bolt 7 to release the limit of the table board 6 on the cover plate 5, so as to facilitate adjusting the distance between the table board 6 and the user. Then, the table board 6 is positioned on the cover plate 5 by the positioning handle bolt 7, so as to facilitate users of different body shapes to use the table board 6.
