DETAILED DESCRIPTION

[0020] 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.

Based on the embodiments of 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.

[0021] See also Figure 1-6 The utility model provides a novel two-stage linkage flip step: it includes a first stepping board 1 and a second stepping board 2, the top surface of the first stepping board 1 is slidably connected to the second stepping board 2, the outer surface of the first stepping board 1 is rotatably connected to a connecting frame 3, the outer surface of the first stepping board 1 is provided with a linkage flipping mechanism 4, and the inner surface of the first stepping board 1 is provided with a bottom adsorption mechanism 5.

[0022] Furthermore, the linkage flip mechanism 4 includes a connecting column 401, a linkage rod 402, a snap-fit ​​groove 403, a return spring 404 and a protective shell 405. The two ends of the first step plate 1 are fixedly connected to the connecting column 401, the outer surface of the first step plate 1 is rotatably connected to the linkage rod 402, the outer surface of the linkage rod 402 is provided with a snap-fit ​​groove 403, one end of the first step plate 1 is fixedly connected to the return spring 404, and the outer surface of the first step plate 1 is fixedly connected to the protective shell 405. Through the arrangement of the connecting column 401, the linkage rod 402, the snap-fit ​​groove 403, the return spring 404 and the protective shell 405, during use, the first step plate 1 and the second step plate 2 can be rotatably connected to the connecting frame 3 through the connecting column 401 and can rotate around the connection. The first step plate 1 and the second step plate 2 are connected by the linkage rod 402 to form a parallel four-bar system. The structure is such that when one of the treads is flipped, the other tread will be driven to flip synchronously to achieve the effect of linked flipping. Since the locking groove 403 on the linkage rod 402 can just be clamped on the connecting column 401, when the first tread 1 and the second tread 2 are folded, the first tread 1 and the second tread 2 and the linkage rod 402 can be stored in the interior of the connecting frame 3 to reduce the space occupied. When the first tread 1 is flipped, since the return spring 404 is fixedly connected at both ends, the return spring 404 will twist. When the external force for flipping the first tread 1 disappears, the return spring 404 will reverse and drive the first tread 1 to be folded. The return spring 404 is wrapped inside by the external protective shell 405 to prevent the return spring 404 from pinching people or objects during use, so that the treads can be flipped in a linked manner when subjected to sufficient pressure and can be easily folded and folded when not needed.

[0023] Furthermore, connecting columns 401 are fixedly connected at both ends of the second step board 2, the second step board 2 is rotatably connected to the connecting frame 3, the connecting column 401 passes through the connecting frame 3 and is rotatably connected to the connecting frame 3, and the first step board 1 and the second step board 2 can be rotatably connected to the connecting frame 3 through the connecting column 401 and can rotate around the connection.

[0024] Furthermore, the linkage rod 402 is rotatably connected to the outer surface of the second step board 2, the number of the linkage rods 402 is two, the engaging groove 403 is slidably connected to the outer surface of the connecting column 401, and the first step board 1 and the second step board 2 are connected by the linkage rod 402 to form a parallel four-bar structure. In this way, when one of the step boards is flipped, it will drive the other step board to flip synchronously to achieve the effect of linkage flipping.

[0025] Furthermore, the other end of the return spring 404 is fixedly connected to the connecting frame 3, and the return spring 404 is sleeved on the outer surface of the connecting column 401. When the first step plate 1 is flipped, the return spring 404 will twist because both ends are fixedly connected with the return spring 404. When the external force for flipping the first step plate 1 disappears, the return spring 404 will reverse and drive the first step plate 1 to be retracted.

[0026] Furthermore, the bottom adsorption mechanism 5 includes a mounting sleeve 501, a top cover plate 502, an internal knob 503, a threaded screw 504, a threaded sleeve 505, a partition plate 506 and a bottom suction cup 507. The inner surface of the first step plate 1 is fixedly connected with the mounting sleeve 501, the inner surface of the mounting sleeve 501 is slidably connected with the top cover plate 502, the inner surface of the mounting sleeve 501 is slidably connected with the internal knob 503, the bottom surface of the internal knob 503 is fixedly connected with the threaded screw 504, the inner surface of the mounting sleeve 501 is fixedly connected with the threaded sleeve 505, the bottom surface of the threaded sleeve 505 is fixedly connected with the partition plate 506, the bottom surface of the threaded screw 504 is fixedly connected with the bottom suction cup 507, and the mounting sleeve 501, the top cover plate 502, the internal knob 503, the threaded screw 504, the threaded screw 505, the partition plate 506, the bottom surface of the threaded screw 504, the bottom suction cup 507, The arrangement of the knob 503, the threaded pin 504, the threaded sleeve 505, the partition plate 506 and the bottom suction cup 507, during use, the installation sleeve 501 is used to install and protect internal components, the top cover plate 502 can be opened for interaction with the interior, and when not in use, the cover plays a protective effect and prevents external objects from falling into the installation sleeve 501, and the threaded pin 504 can be rotated by the internal knob 503 to drive it to move up and down on the threaded sleeve 505, and drive the bottom suction cup 507 to move, and the partition plate 506 divides the installation sleeve 501 into two parts, and when the first step plate 1 contacts the ground and the bottom suction cup 507 also moves down to contact the ground, the bottom suction cup 507 can adsorb the ground to have a fixing effect and can prevent the linkage flip mechanism 4 from resetting.

[0027] Furthermore, the inner surface of the internal knob 503 is provided with an annularly distributed anti-skid groove, and the threaded screw 504 passes through the threaded sleeve 505 and the partition baffle 506.

[0028] Working principle: A new type of two-stage linkage flip step. During use, the first tread 1 and the second tread 2 can be rotatably connected to the connecting frame 3 through the connecting column 401 and can rotate around the connection. The first tread 1 and the second tread 2 are connected by a linkage rod 402 to form a parallel four-bar structure. In this way, when one of the treads is flipped, it will drive the other tread to flip synchronously to achieve a linkage flipping effect. Since the engaging groove 403 provided on the linkage rod 402 can just be stuck on the connecting column 401, when the first tread 1 and the second tread 2 are folded, the first tread 1 and the second tread 2 and the linkage rod 402 can all be stored in the interior of the connecting frame 3 to reduce space occupied. When the first tread 1 is flipped, since both ends are fixedly connected with the return spring 404, the return spring 404 will twist. When the outer surface of the first tread 1 is flipped After the force disappears, the return spring 404 will reverse and drive the first stepping plate 1 to retract. The return spring 404 is wrapped inside the external protective shell 405. The mounting sleeve 501 is used to install and protect internal components. The top cover 502 on the top can be opened for interaction with the interior. When not in use, the cover plays a protective effect and prevents external objects from falling into the mounting sleeve 501. By rotating the threaded screw 504 through the internal knob 503, it can be driven to move up and down on the threaded sleeve 505, and drive the bottom suction cup 507 to move. The partition plate 506 divides the mounting sleeve 501 into two parts. When the first stepping plate 1 contacts the ground and the bottom suction cup 507 also moves down to contact the ground, the bottom suction cup 507 can adsorb the ground to fix it and prevent the linkage flip mechanism 4 from resetting, thus completing a new type of two-stage linkage flip step.
