Description
Technical Field
[0001] The utility model belongs to the technical field of wheelchairs, and in particular relates to a folding structure of an airplane wheelchair. Background Art
[0002] A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled to recover at home, be transported around, see a doctor, and go out for activities. Wheelchairs not only meet the needs of the physically disabled and those with limited mobility, but more importantly, they facilitate family members to move and take care of patients, and enable patients to exercise and participate in social activities with the help of wheelchairs.
[0003] The existing aircraft wheelchair is inconvenient to store the seat frame when in use, and the seat frame cannot be folded and stored, which affects the portability of the device, and the applicability is not high, and it is inconvenient to adjust the use angle of the armrest. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides an airplane wheelchair folding structure, which has the characteristics of simple structure and low use cost.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an aircraft wheelchair folding structure, comprising a lower circular gear groove member, a pin is arranged through the interior of the lower circular gear groove member, a spring is arranged in the middle of the interior of the lower circular gear groove member, a gear is arranged on one side of the spring, an upper circular gear groove member is arranged on one side of the gear, and a button is arranged inside the upper circular gear groove member corresponding to the gear.
[0006] Preferably, an annular tooth groove is provided inside the upper circular gear groove member corresponding to the gear, and a limit stop ring is provided on one side of the upper circular gear groove member corresponding to the button.
[0007] Preferably, a placement groove is provided inside the lower circular gear groove corresponding to the spring, and a pin passes through the lower circular gear groove, the spring and the gear and is installed inside the upper circular gear groove.
[0008] Preferably, the surfaces of the lower circular gear groove member and the upper circular gear groove member are passivated, and a non-slip pad is provided on one side surface of the button.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model adopts the method of movably inserting the gear into the placement groove or the annular tooth groove to position it, so that the armrest of the airplane wheelchair can be quickly and stably rotated to fold. The equipment has a simple structure and is easy to use, which saves human resources and the space occupied by the wheelchair, and improves the use effect of the equipment. After the gear is re-inserted into the annular tooth groove inside the upper circular gear groove part, it can be limited to ensure that the lower circular gear groove part and the upper circular gear groove part will not be misaligned, thereby ensuring the convenience and stability of the equipment and improving the use quality.

[0012] Figure 2 It is the structural assembly drawing of the utility model;
[0013] Figure 3 It is a schematic diagram of the structure of the utility model in use state.
[0014] In the figure: 1. pin; 2. lower circular gear groove; 3. spring; 4. upper circular gear groove; 5. button; 6. gear. DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 The utility model provides the following technical solutions: an aircraft wheelchair folding structure, comprising a lower circular gear groove part 2, a pin 1 is arranged through the interior of the lower circular gear groove part 2, a spring 3 is arranged in the middle of the interior of the lower circular gear groove part 2, a gear 6 is arranged on one side of the spring 3, an upper circular gear groove part 4 is arranged on one side of the gear 6, and a button 5 is arranged inside the upper circular gear groove part 4 corresponding to the gear 6.
[0017] Specifically, an annular tooth groove is provided inside the upper circular gear groove member 4 corresponding to the gear 6 , and a limit stop ring is provided on one side of the upper circular gear groove member 4 corresponding to the button 5 .
[0018] By adopting the above technical solution, the gear 6 is ensured to be positioned stably and firmly, misalignment is prevented, and the stability of the equipment is ensured.
[0019] Specifically, a placement groove is provided inside the lower circular gear groove part 2 corresponding to the spring 3 , and the pin 1 passes through the lower circular gear groove part 2 , the spring 3 and the gear 6 and is installed inside the upper circular gear groove part 4 .
[0020] By adopting the above technical solution, the guiding stability of the gear 6 is ensured when it moves, the situation that the gear 6 cannot be inserted due to deviation is prevented, and the stability of the equipment is improved.
