Description

Dual-functional treadmill Technical Field The utility model relates to sports equipment, in particular to a difunctional stepper. Background With the increasing awareness of health, the demand for fitness equipment is growing. The stepper is popular as a common indoor body-building device because it can simulate the actions of climbing stairs or walking, help users exercise lower limb muscles, and improve cardiopulmonary function. However, most of the existing treadmills only support a single up-and-down stepping movement mode, have a single function, and cannot meet the requirements of users on diversified movement experiences. In addition, a single movement pattern tends to cause the user to feel boring when using for a long time, and the user cannot exercise the coordination of the core muscle group and the body comprehensively. In recent years, some treadmills have appeared on the market that attempt to introduce a variety of exercise modes, such as by manually adjusting the pedal angle or changing parts to achieve different exercise modes. However, these designs have obvious limitations, including complex operation, manual adjustment or replacement of parts by a user, time and effort waste, and damage or potential safety hazard of equipment due to improper operation, and complex structure, which increases manufacturing cost and maintenance difficulty of equipment. (reference "201420359929.9-a novel stepping machine" utility model patent) In order to solve the problems, the utility model provides a stepping machine with a switching structure for two movement modes of 'stepping up and down' and 'twisting left and right', which realizes quick and convenient switching of the two modes. Disclosure of Invention The utility model discloses a dual-function stepper, which solves the problems of complex mode switching operation and complex structure of the prior stepper. A dual-function pedal apparatus is composed of a base with a rotary axle pivoted to a pedal connecting mechanism for connecting a pair of pedal units and a linking mechanism acting between a pair of pedal units, a left-right twisting pedal mode for said pedal units when said linking mechanism is relative to said base, a vertical pedal mode for said pedal units when said pedal connecting mechanism is relative to said base, The treadmill also comprises a key locking mechanism, wherein the key locking mechanism comprises a fixing part which is connected with the end part of the rotating shaft and keeps fixed relative position with the base, and The limiting pin connecting piece is arranged on the fixing part, the limiting pin connecting piece is movably connected with the fixing part to form a lever structure, limiting pins are respectively arranged at two ends of the limiting pin connecting piece, and one end of each limiting pin is movably connected with the end part of the limiting pin connecting piece; The pedal connecting mechanism is provided with a pedal connecting mechanism, and the pedal connecting mechanism is provided with a pedal connecting mechanism, wherein the pedal connecting mechanism is provided with a pedal connecting mechanism, and the pedal connecting mechanism is provided with a pedal connecting mechanism; In the left-right twisting stepping mode, one limiting pin partially penetrates through the limiting pin moving hole and falls into the first limiting hole, and the other limiting pin leaves the second limiting hole; In the stepping mode, one limiting pin partially penetrates through the limiting pin movable hole and falls into the second limiting hole, and the other limiting pin leaves the first limiting hole. The utility model provides a key locking mechanism for switching the motion modes of a stepping machine, namely 'up and down stepping' and 'left and right twisting stepping'. The fixed part is connected with the rotating shaft and then forms a whole with the base, the limiting pin connecting piece is movably connected with the fixed part to form a lever structure, two ends of the limiting pin connecting piece are provided with limiting pins which are movably connected, one limiting pin is used for limiting the relative rotation between the linkage mechanism and the base, and the other limiting pin is used for limiting the relative rotation between the pedal connecting mechanism and the base. Therefore, the convenient switching between the left-right twisting stepping mode and the up-down stepping mode is realized by pressing the limiting pin connecting sheet. The following provides several alternatives, but not as additional limitations to the above-described overall scheme, and only further additions or preferences, each of which may be individually combined for the above-described overall scheme, or may be combined among multiple alternatives, without technical or logical contradictions.
