[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A foldable wheel skating device comprises a shell, a first wheel frame, a second wheel frame, a linkage frame and a locking mechanism, and a first elastic member, characterized in that: the upper end of the first wheel frame is rotatably arranged on the shell, the lower end of the first wheel frame is provided with a first walking wheel, the upper end of the second wheel frame is rotatably arranged on the shell, and the lower end of the second wheel frame is provided with a second walking wheel, the linkage frame can be movably arranged in the shell between a first position and a second position, one end of the linkage frame is rotatably connected to the first wheel frame, and the other end is rotatably connected to the second wheel frame. When the linkage frame is in the first position, the first wheel frame and the second wheel frame are unfolded relative to the shell and are in a usable state. When the linkage frame is in the second position, the first wheel frame and the second wheel frame are folded close to the shell, the first elastic member drives the linkage frame to move to the first position, the locking mechanism can lock the linkage frame to keep it in the second position, and the locking mechanism can also lock the linkage frame to keep it in the first position.

[0007] By adopting the above scheme, the linkage frame can be movably arranged in the shell between the first position and the second position, and the two ends of the linkage frame are respectively connected to the first wheel frame and the second wheel frame, and the first wheel frame and the second wheel frame can be maintained in the second position through the cooperation between the linkage frame and the locking mechanism, so that the linkage frame can be more stable when maintaining the second position, and the first elastic member drives the linkage frame to move to the first position, so that when the linkage frame is in the first position, the linkage frame and the first wheel frame and the second wheel frame cooperate more stably, thereby increasing reliability during use, and the locking mechanism can also lock the linkage frame to keep it in the first position, which can further increase safety and stability during use.

[0008] The locking mechanism includes a locking piece, which is movably arranged in the shell body up and down, and the bottom of the locking piece is provided with a first locking groove and a second locking groove, and the linkage frame is provided with a first pin shaft which can be locked by the first locking groove or the second locking groove.

[0017] By adopting the above solution, the first wheel frame is rotatably connected to the linkage frame through the first pin shaft, and the second wheel frame is rotatably connected to the linkage frame through the second pin shaft, which can facilitate the unfolding and folding of the first wheel frame and the second wheel frame relative to the shell.

[0018] The second wheel frame is rotatably connected to the housing via a second shaft, and the first elastic member is a tension spring connected between the second shaft and the linkage frame.

[0019] By adopting the above scheme, the second wheel frame is rotatably connected to the shell through the second axis, which can facilitate the expansion and folding of the second wheel frame relative to the shell. Using a tension spring as the first elastic member can not only meet the elastic requirements of the first elastic member, but also make the second wheel frame more stable in the expanded state.

[0020] The housing is formed with an elongated clearance hole for the driving pin to pass through.

[0021] By adopting the above solution, an elongated clearance hole for the driving pin to pass through is formed in the housing, which can further limit the displacement of the locking member.

[0022] The first wheel frame includes two first plate-like swing arms, which are distributed on both sides of the shell in parallel and oppositely, and the two first plate-like swing arms are rotatably connected to the shell through a first axis, the first axis crosses the shell and the two ends are respectively connected to the two first plate-like swing arms, and / or the second wheel frame includes two second plate-like swing arms, which are distributed on both sides of the shell in parallel and oppositely, and the two second plate-like swing arms are rotatably connected to the shell through a second axis, the second axis crosses the shell and the two ends are respectively connected to the two second plate-like swing arms.

One end of the linkage frame 2 is rotatably connected to the first wheel frame 4 through a first pin shaft 21, and the other end is rotatably connected to the second wheel frame 5 through a second pin shaft 22. When the linkage frame 2 is in the first position, the first wheel frame 4 and the second wheel frame 5 are unfolded relative to the shell 1 and are in a usable state. When the linkage frame 2 is in the second position, the first wheel frame 4 and the second wheel frame 5 are folded close to the shell 1. The first elastic member 23 can drive the linkage frame 2 to move to the first position, so that when the linkage frame 2 is in the first position, the linkage frame 2 cooperates with the first wheel frame 4 and the second wheel frame 5 more stably, thereby increasing reliability during use.

[0037] The locking mechanism 3 includes a locking member 31, an operating member 32, and a second elastic member 33. The locking member 31 can be movably arranged in the housing 1 up and down. The locking member 31 includes two parallel opposite side plates 315 and a top plate 316 connected between the upper edges of the two side plates 315. The two side plates 315 and the top plate 316 are integrally stamped and formed by metal plates. The operating member 32 passes through between the two side plates 315. A driving pin 321 is arranged on the operating member 32. The two side plates 315 are formed with oblique holes 313 for the driving pin 321 to pass through. The housing 1 is also formed with an elongated clearance hole 18 for limiting the driving pin 321. The elongated clearance hole 18 can make the driving pin 321 only move horizontally. The lower edges of the two side plates 315 are respectively formed with a first locking groove 311, a second locking groove 312 and The arc-shaped portion 314 protrudes upward between the first locking groove 311 and the second locking groove 312, the linkage frame 2 is provided with a first pin shaft 21 which can be locked by the first locking groove 311 or the second locking groove 312, and the shell 1 is formed with a first arc-shaped limiting hole 111 for the first pin shaft 21 to pass through and a second arc-shaped limiting hole 112 for the second pin shaft 22 to pass through. When the linkage frame 2 is in the first position, the first arc-shaped limiting hole 111 can make the first pin shaft 21 move along the first arc-shaped limiting hole 111, and the second arc-shaped limiting hole 112 can make the second pin shaft 22 move along the second arc-shaped limiting hole 112, so that the first pin shaft 21 moves from the second locking groove 321 through the arc-shaped portion 314 to be embedded in the first locking groove 311 to limit the movement of the linkage frame 2. The wheel frame 4 and the second wheel frame 5 are in an unfolded state. When the linkage frame 2 is in the second position, the first pin shaft 21 moves along the first arc-shaped limiting hole 111, and the second pin shaft 22 moves along the second arc-shaped limiting hole 112, so that the first pin shaft 21 moves from the first locking groove 311 through the arc-shaped portion 314 to be embedded in the second locking groove 312 to limit the movement of the linkage frame 2. At this time, the first wheel frame 4 and the second wheel frame 5 are in a folded state, and the main body 11 of the shell 1 is formed with a clearance hole 17 for one end of the operating member 32 to extend out.
