[0019] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0020] Embodiment: A lower pull rod limiting mechanism for a camping vehicle comprises a lower pull rod 1 and a fixing member 2, wherein the lower pull rod is hinged in the fixing member, and a first limiting surface 3 and a second limiting surface 4 are provided on the fixing member, wherein the first limiting surface limits the movement of the upper end surface 5 of the lower pull rod, and the second limiting surface limits the movement of the side end surface 6 of the lower pull rod, and a stop surface 9 is provided at the bottom of the fixing member for limiting the movement of the lower end surface 10 of the lower pull rod.
[0021] The fixing piece is in an X shape, the lower pull rod is in an elongated strip shape, and positioning openings 7 for inserting the lower pull rod are provided at the four corners of the X shape.
[0022] One end of the lower pull rod is hinged in the positioning opening, and the interior of the positioning opening is hollow.
[0023] The positioning opening is open toward the outer side of the fixing member, and is closed toward the inner side of the fixing member. The second limiting surface is located on the inner side surface of the positioning opening.
[0024] The lower end of the positioning port is open and communicated with the outside of the positioning port, the upper end of the positioning port is hollow, the outer edge of the upper end of the positioning port is closed, and the first limiting surface is located at the upper edge of the positioning port.
[0025] A boss 11 is provided on the inner side of the bottom of the positioning opening, extending outward, and the stop surface is located on the boss.
[0026] A cross-shaped reinforcing rib 8 is provided in the middle of the upper end of the fixing member.
[0027] The limiting mechanism for the lower pull rod of the camping vehicle is as follows: when the camping vehicle is fully unfolded, the upper end surface of the lower pull rod contacts the first limiting surface of the fixing member, the side end surface of the lower pull rod contacts the second limiting surface of the fixing member, and the lower end surface of the lower pull rod contacts the stop surface of the fixing member, thereby limiting the downward movement of the lower pull rod as a whole and providing effective support for the lower pull rod, making the bottom unfolding structure of the camping vehicle more secure and preventing accidental folding. When folding is required, the fixing member is pulled upward to release the lower pull rod from the fixing member, and the lower pull rod rotates in the fixing member, causing the lower pull rods located at the four X-shaped corners of the fixing member to move together and move closer to each other, thereby completing the folding of the camping vehicle bottom.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
