DETAILED DESCRIPTION

[0025] See Figure 1-Figure 7 As shown, the technical solution adopted in this specific embodiment is: it includes a lifting main frame 6, a bottom mounting plate 5 is installed below the side of the lifting main frame 6, a rear storage rack 4 is provided below the rear end of the lifting main frame 6, and a connecting plate 7 is bolted to the middle of the rear end of the lifting main frame 6, an armrest connecting plate 3 is installed on the outside of the connecting plate 7, a side armrest 2 is installed above the armrest connecting plate 3, and a backrest cushion 1 is installed on the top of the lifting main frame 6.

[0026] More specifically, there are two side armrests 2 and two armrest connecting plates 3, which are symmetrically arranged at both ends of the connecting plate 7. The side armrests 2 facilitate the support of the user's hands and enhance the user's experience, while the armrest connecting plates 3 can be used for folding and storing the side armrests 2.

[0027] More specifically, the main lifting frame 6 includes a lifting shell 63, the inner cavity of which is slidably connected to a lifting column 67. The top of the lifting column 67 is fixedly connected to a connecting lifting bracket 62. The top of the connecting lifting bracket 62 is rotatably connected to a backrest cushion connecting frame 61 via a backrest adjustment assembly 69. The side of the lifting shell 63 is fixedly connected to a side auxiliary frame 64. The outer end of the side auxiliary frame 64 is provided with a bottom plate rotating mechanism 65. Below the bottom plate rotating mechanism 65 is a bottom plate connecting frame 66. The back of the lifting shell 63 is provided with an adjustment cross bar 68. During installation, the operator can install the bottom mounting plate 5, connecting plate 7, backrest cushion 1 and rear storage rack 4 on the main lifting frame 6. The lifting column 67 can be raised and lowered based on the lifting shell 63, and the support angle of the backrest cushion 1 can be adjusted through the backrest adjustment assembly 69. The bottom plate rotating mechanism 65 allows the main lifting frame 6 to be adjusted based on the bottom mounting plate 5, improving the user experience.

[0028] To be more specific, the bottom mounting plate 5 is installed on the lifting main frame 6 through the bottom plate connecting frame 66, the connecting plate 7 is installed on the back of the lifting main frame 6, the backrest cushion 1 is installed on the lifting main frame 6 through the backrest cushion connecting frame 61, and the rear storage rack 4 is installed on the lifting main frame 6 through the adjusting cross bar 68.

[0029] To be more specific, the connecting plate 7 is provided with mounting bolt holes 701 for mounting bolts, and the side of the connecting plate 7 is fixedly connected with a side mounting plate 702 for the handrail connecting plate 3 .

[0030] The working principle of the present utility model is as follows: when it is necessary to install and use the equipment, the staff only needs to use bolts and install the equipment to the designated position through the bottom mounting plate 5. After the installation is completed, the user can use the equipment normally. During use, the user can adjust the backrest cushion 1 to obtain the relative height by lifting the main frame 6, and adjust the support angle of the backrest cushion 1 through the backrest cushion connecting frame 61. The user can fold or unfold the side armrests 2 through the armrest connecting plate 3, and use the side armrests 2 to support and place both hands. During use, the user can also place certain items through the rear storage rack 4, thereby increasing the placement capacity of the riding equipment. Among them, when the user needs to store his equipment, he only needs to loosen the connection between the lifting shell 63 and the bottom mounting plate 5 by adjusting the cross bar 68, and then he can put down his equipment and store the side armrests 2.

[0031] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
