Example Embodiment
[0032] Example 1
[0033] Such as figure 1 A wheel structure is shown, the main body of which is composed of a wheel body 1, a shaft 2 and a support rod 3. A two-way ratchet mechanism 210 is provided at the connection position of the shaft 2 and the support rod 3. The ratchet of the two-way ratchet mechanism 210 Fixed on the shaft 2, the pawl and the adjustment switch for controlling the pawl are set on the support rod 3. Under the action of the bidirectional ratchet mechanism 210, the shaft 2 can be adjusted to rotate in only one direction, and then set on the shaft 2. The wheel body 1 at the end can only rotate in one direction along with the adjustable shaft 2.
[0034] In this embodiment, a backstop rod 220 is provided on the shaft 2. The backstop rod 220 is flexibly arranged on the shaft 2, that is, it is sleeved on the shaft 2 through a ring at one end, and stops when the shaft 2 rotates. The retraction lever 220 will not swing along with it. When in use, one end of the retr...
Example Embodiment
[0044] Example 2
[0045] The difference in this embodiment on the basis of embodiment 1 is that in this embodiment, as image 3 As shown, the wheel structure is arranged on both sides of the hull of the kayak 6 through the connecting piece 4. This connection method is more suitable for the case where there is not enough space at the stern to connect with the base 420, and the two sides of the hull have enough space with the base. The kayak 6 connected by 420; the connection method is specifically: the connecting piece 4 is set on both sides of the hull of the kayak 6 through the base 420, and the base 420 and the hull are installed by sealing screws 470; the support rod 3 of the wheel structure Inserted into one end of the sleeve 410 of the connecting piece 4, and movably connected to the connecting piece 4 through the limit of the spring pin 310 and the positioning hole 411, so that the wheel structure is installed on both sides of the kayak 6 through the connecting piece 4; Wh...
Example Embodiment
[0047] Example 3
[0048] The difference of this embodiment on the basis of embodiment 1 is that in this embodiment, the wheel structure is arranged on the bottom of the kayak 6 through the connecting member 4, such as Figure 5 Shown.
