[0022] 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.

[0023] The utility model provides Figure 1-3A racing wheelchair accessory shown in the figure includes an auxiliary ring 1, and the auxiliary ring 1 includes a hand push ring 101 and a connecting ring 102. The hand push ring 101 is annular in structure, and the hand push ring 101 acts on the manual movement of the racing wheelchair. The connecting ring 102 is fixedly arranged on the outer wall of the hand push ring 101, and the connecting ring 102 acts on the support of the position space of the hand push ring 101. A through hole 104 for installing the connecting ring 102 on the wheelchair is opened in the middle of the connecting ring 102. The connecting ring 102 is circular, and the circular setting of the connecting ring 102 corresponds to the shape of the hand push ring 101, so that the connecting ring 102 can be fixed along one side of the hand push ring 101, thereby enhancing the stability of the fixation with the hand push ring 101, and at the same time, the connecting ring 102 can be supported when the hand push ring 101 is used under force. The force is uniform, thereby strengthening the firmness between the hand push ring 101 and the wheelchair and the flexibility of the hand push ring 101 in rotation. The auxiliary ring 1 also includes a groove 103, which is opened on the outer wall of the connecting ring 102. The groove 103 acts to increase the operating space of the hand push ring 101. The hand push ring 101 and the connecting ring 102 are fixedly arranged. When installed with the racing wheelchair, the connecting ring 102 is between the wheelchair and the hand push ring 101. Between the hand push ring 101 and the connecting ring 102, because the hand push ring 101 is annular, the connecting ring 102 is also circular, and the inner diameter of the hand push ring 101 is larger than the diameter of the connecting ring 102, therefore, the outer wall of the connecting ring 102 protrudes beyond the diameter range of the connecting ring 102, providing an operating space for the user to contact the hand push ring 101. The arrangement of the other structures between the push ring 101 and the connecting ring 102 makes the push ring 101 a simple ring structure. When the user rotates the wheelchair with the help of the push ring 101, it can also avoid collision injuries to the user's hands due to the internal structure of the push ring 101. Through the arrangement of the single ring structure of the push ring 101, when the user pushes the push ring 101, it can avoid slow or cautious use movements caused by the complex structure of the push ring 101, which provides convenience for the use of the push ring 101 and also improves the safety of the use of the push ring 101. The connecting ring 102 has a through hole 104 in the middle, so that the connecting ring 102 can be installed on the wheelchair by bolts or screws, so that the push ring 101 1 can be stably indirectly installed on the wheelchair. Through the fixed contact between one side of the push ring 101 and the connecting ring 102, the connection area of ​​the fixed installation of the push ring 101 is increased, thereby effectively improving the firmness of the position installation of the push ring 101 and the effectiveness of pushing and using. In addition, a groove 103 is provided on the connecting ring 102. The opening of the groove 103 makes the cross section of the connecting ring 102 present an I-shape, so that when the user grasps the push ring 101, the hand grasping space can be increased, thereby adding use space for the use of the push ring 101. When the user pushes the push ring 101, because the user sits on the wheelchair and stretches out his arms to use the push ring 101, the opening of the groove 103 avoids the phenomenon of insufficient force caused by too small extension space for the user's hands.It effectively increases the space for the user's hand to grip and apply force, thereby providing the user with convenience and comfort, and further enhancing the flexibility and practicality of the hand push ring 101;

[0024] Preferably, the outer wall of the hand push ring 101 is provided with a protective structure 2, which includes a protective sleeve 201, which is sleeved on the outer wall of the hand push ring 101, and the protective sleeve 201 acts on the safety of the hand push ring 101. The protective structure 2 also includes a protective block 202, which is trapezoidal and fixedly arranged on the inner wall of the protective sleeve 201 at equal intervals, and the protective block 202 acts on the support of the protective sleeve 201. The protective sleeve 201 and the protective block 202 are either elastic rubber or elastic silicone. The cross-section of the protective sleeve 201 is C-shaped. The C-shaped cross-section of the protective sleeve 201 allows the protective sleeve 201 to be sleeved on the outer wall of the hand push ring 101 through its own elastic tightness, thereby ensuring the stability of the protective sleeve 201 sleeved on the outer wall of the hand push ring 101. The protective sleeve 201 is easy to assemble and disassemble, has high flexibility and low cost of use. The protective sleeve 201 and the protective block 202 are both made of elastic rubber. The setting of the elastic rubber material of the protective sleeve 201 and the protective block 202 can increase the friction resistance with the user's hand, thereby preventing the user's hand from slipping out when the hand push ring 101 is applied with force to rotate, thereby ensuring the effectiveness of the use of the hand push ring 101 and enhancing the safety of the user's hand. The protective blocks 202 are arranged at equal intervals on the inner wall of the protective sleeve 201, and the protective blocks 202 are in contact with the outer wall of the hand push ring 101. When the user uses it, as the user's hand moves against When the protective sleeve 201 applies pressure, the protective block 202 will also be squeezed by the user's hand while the protective sleeve 201 is under pressure. When both the protective sleeve 201 and the protective block 202 are under pressure, as the protective sleeve 201 and the protective block 202 are elastically deformed, the protective block 202 will squeeze the outer wall of the hand pushing ring 101. In this process, the protective block 202 squeezes the outer wall of the hand pushing ring 101 to fill the space between the protective sleeve 201 and the hand pushing ring 101, thereby preventing the protective sleeve 201 from directly squeezing the outer wall of the hand pushing ring 101 when the user applies a large force, thereby causing the user's hand to indirectly collide with the hand pushing ring 101. Under the setting of the protective block 202, when the protective sleeve 201 is under pressure, The protective block 202 can be located between the protective sleeve 201 and the hand push ring 101 to play the role of spacing support, so as to enhance the elastic support performance of the protective sleeve 201, thereby effectively improving the safety and effectiveness of the use of the protective sleeve 201. At the same time, under the setting of the protective block 202, after the protective sleeve 201 is pressed by the user's hand, it can also use the support of the protective block 202 to restore its original shape more quickly, so that the protective sleeve 201 can provide effective support for the user to reuse the hand push ring 101, effectively improving the convenience of using the protective sleeve 201, and also enhancing the efficiency of the user's manual rotation of the racing wheelchair. In addition, under the setting of the protective sleeve 201 and the protective block 202, the use range of the hand push ring 101 is also increased.When the user applies force to the push ring 101, the user can apply force by contacting the protective cover 201 without directly contacting the outer wall of the push ring 101, which further expands the use range of the push ring 101, thereby enhancing the comfort and flexibility of the use of the push ring 101, and also prolongs the service life of the push ring 101, and enhances the practicality of the push ring 101.
