[0028] like Figure 1-Figure 5 As shown, a high-safety sports equipment includes a bracket 1, the bracket 1 is fixedly connected to a seat cushion 2 and a foot rest 3, a support leg 4 is arranged at the bottom of the bracket 1, the support leg 4 includes a support tube 401 fixedly connected to the bracket 1, an extension rod 402 is coaxially slidably arranged in the support tube 401, a locking screw 404 is radially threaded at the end of the support tube 401, and an auxiliary rod 403 is arranged at the end of the extension rod 402.

[0029] Two extension rods 402 are arranged in the support tube 401 of the above-mentioned Roman chair. When in use, the locking screw 404 is loosened, and the two extension rods 402 can be respectively pulled out from the two ends of the support tube 401, and then the locking screw 404 is tightened to achieve locking between the extension rod 402 and the support tube 401. The setting of the extension rod 402 can increase the overall length of the support leg 4, thereby expanding the support range of the support leg 4 and improving the stability and safety of the Roman chair; and the telescopic length of the extension rod 402 can be adjusted arbitrarily according to the venue, so that the Roman chair is suitable for different venues, thereby improving the practicality of the Roman chair; an auxiliary rod 403 is arranged at one end of the extension rod 402 located outside the support tube 401, and the auxiliary rod 403 can be arranged vertically or horizontally. When it is arranged horizontally, it can further expand the support range of the support leg 4 and further improve the stability and safety of the Roman chair. When it is arranged vertically, it can be used to adjust the balance of the Roman chair and improve the stability of the Roman chair.

[0030] A further improvement is, Figure 6 The end of the extension rod 402 is provided with a plug-in slot 4025 along its radial direction, and the auxiliary rod 403 is distributed along the radial direction of the extension rod 402 and plugged into the plug-in slot 4025. When the auxiliary rod 403 is plugged into the plug-in slot 4025, the auxiliary rod 403 can be adjusted to be distributed horizontally or vertically by rotating the extension rod 402. When the auxiliary rod 403 is distributed horizontally, as shown in FIG. Figure 4 As shown, the support tube 401, the extension rod 402 and the auxiliary rod 403 all play the role of supporting the Roman chair, expanding the support range and improving the stability of the Roman chair; when the auxiliary rod 403 is arranged vertically, as shown in FIG. Figure 2 As shown, the bottom end of the auxiliary rod 403 is in contact with the ground. By adjusting the position of the auxiliary rod 403 and the plug-in slot 4025, the height of the bottom end of the auxiliary rod 403 can be adjusted, so that the horizontal state of the support foot 4 can be adjusted through the auxiliary rod 403, so that the Roman chair can be used on an uneven bottom surface, and can also be adjusted to a horizontal state through the auxiliary rod 403, thereby improving the stability and safety of the Roman chair.

[0031] A further improvement is, Figure 6-Figure 8 As shown, the auxiliary rod 403 is provided with a guide groove 4031 along its own extension direction, and a positioning piece connected to the inner wall of the plug-in groove 4025 is provided inside the guide groove 4031. The positioning piece is fixed in the plug-in groove 4025 and is located inside the guide groove 4031, so that the auxiliary rod 403 can be restricted inside the plug-in groove 4025 by the positioning piece to prevent the auxiliary rod 403 from being separated from the extension rod 402, and the positioning piece is slidably connected with the guide groove 4031, so that the auxiliary rod 403 can slide inside the plug-in groove 4025 to adjust its own position.

[0032] A further improvement is, Figure 6 and Figure 7As shown, the positioning member is a bolt 4023, and the inner walls on both sides opposite to the insertion slot 4025 are respectively provided with coaxial stepped holes and threaded holes. The bolt 4023 passes through the stepped hole and the guide slot 4031 in sequence and then is threadedly connected with the threaded hole. The bolt 4023 passes through the guide slot 4031, which can realize the connection between the extension rod 402 and the auxiliary rod 403 to prevent the two from being separated, and the bolt 4023 and the guide slot 4031 are mutually limited, which can guide the movement of the auxiliary rod 403; the head end of the bolt 4023 is connected to the stepped hole, so that the bolt head can sink into the stepped hole, preventing the bolt head from protruding from the surface of the extension rod 402 and affecting the retraction and release of the extension rod 402 inside the support tube 401; the stud part of the bolt 4023 is connected to the threaded hole Then, when the bolt 4023 is tightened, the inner walls on both sides of the plug-in slot 4025 can be brought close to each other through the bolt 4023, so that the auxiliary rod 403 can be clamped by the inner walls on both sides of the plug-in slot 4025, thereby realizing the positioning of the auxiliary rod 403, and improving the firmness of the fixation between the auxiliary rod 403 and the extension rod 402, and ultimately improving the stability of the Roman chair; and when the bolt 4023 is removed from the threaded hole and the step hole, the extension rod 402 and the auxiliary post 403 can also be separated, which improves the convenience of repairing the Roman chair.

[0033] A further improvement is, Figure 6 and Figure 7 As shown, both inner walls opposite to the insertion slot 4025 are provided with anti-skid pads 4024. The anti-skid pads 4024 can be rubber pads, which increase the friction between the extension rod 402 and the support tube 401, thereby improving the firmness of the fixation between the two and improving the stability of the Roman chair.

[0034] A further improvement is, Figure 7 As shown, the extension rod 402 is provided with an inserting hole 4026 along its axial direction for the auxiliary rod 403 to enter, and the end of the inserting hole 4026 is communicated with the inserting groove 4025 .

[0035] When in use, the auxiliary post 403 is slid until the bolt 4023 abuts against the end of the guide groove 4031. At this time, the auxiliary post 403 can be rotated around the bolt 4023 to a direction parallel to the axial direction of the extension rod 402, and then the auxiliary rod 403 is inserted into the plug hole 4026, so that the auxiliary rod 403 can be stored inside the extension rod 402. At the same time, the extension rod 402 can be stored inside the support tube 401, which can reduce the space occupancy rate of the Roman chair when it is stored. Figure 3 and Figure 5 As shown, when the auxiliary rod 403 is axially arranged along the extension rod 402 , it can slide axially along the extension rod 402 , thereby further extending the length of the support leg 4 and further improving the stability of the support leg 4 .

[0036] A further improvement is that the length of the auxiliary rod 403 is less than or equal to the length of the extension rod 402. In this way, the auxiliary rod 403 can be completely stored inside the extension rod 402, which improves the convenience of storing the Roman chair.

[0037] A further improvement is, Figure 6 and Figure 7 As shown, the extension rod 402 is provided with a plurality of first positioning holes 4022 and second positioning holes 4021 along its radial direction for inserting the locking screws 404. The first positioning holes 4022 and the second positioning holes 4021 are arranged at equal intervals along the axial direction of the extension rod 402. The first positioning holes 4022 are arranged parallel to the extension direction of the plug-in slot 4025, and the second positioning holes 4021 are arranged perpendicular to the extension direction of the plug-in slot 4025. The first positioning hole 4022 and the second positioning hole 4021 cooperate with the locking screw 404 to improve the reliability of the connection between the extension rod 402 and the support tube 401. When the locking screw 404 is plugged into the first positioning hole 4022, the auxiliary rod 403 can be locked into a vertical state. At this time, the height of the auxiliary rod 403 can be adjusted by sliding it, thereby adjusting the horizontality of the Roman chair; when the locking screw 404 is plugged into the second positioning hole 4021, the auxiliary rod 403 can be locked into a horizontal state, thereby further expanding the supporting range of the support leg 4 through the auxiliary rod 403, thereby improving the stability of the Roman chair.

[0038] A further improvement is, Figure 3-Figure 5 As shown, the auxiliary rod 403 is detachably connected with an anti-sliding block 405. The anti-sliding block is a rubber block, on which a stud is arranged, the stud passes through the guide groove 4031, and a nut is arranged on the stud, and the anti-sliding block 405 and the auxiliary rod 403 are fixed by the stud and the nut, and the anti-sliding block 405 can increase the anti-slip effect between the auxiliary rod 403 and the ground, thereby improving the anti-slip performance of the Roman chair and improving the safety of the Roman chair.
