Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The plug-in folding mechanism for the foldable vehicle shown in the attached figure 1 comprises a first rod piece 1, a second rod piece 2 and a sleeve body 3; the sleeve body 3 is sleeved on the first rod piece 1; the second rod 2 can be inserted and pulled in the length direction of the first rod 1, so that the end part of the second rod 2 can enter and exit the sleeve body 3, and the second rod 2 can be switched between a fixed state and a foldable state relative to the first rod 1. That is, in a fixed state (as shown in fig. 2-3), the second rod 2 and the first rod 1 are in a relatively close state, at this time, the end of the second rod 2 extends into the sheath 3, and the sheath 3, the first rod 1 and the second rod 2 are fixed as a whole; in a foldable state (as shown in fig. 1), the second rod 2 is away from the first rod 1, and at this time, the end of the second rod 2 is separated from the sheath 3, and at this time, the second rod 2 can rotate relative to the first rod 1. The user can switch the second rod 2 and the first rod 1 between a relatively close state and a relatively far state through the insertion and pulling actions.
In order to realize that the two rod pieces can be relatively inserted and pulled out and can rotate in a relatively far away state, a pin body 4 is arranged on one of two adjacent end parts of the first rod piece 1 and the second rod piece 2, and a straight groove for the pin body 4 to move back and forth is arranged on the other end part. In this embodiment, the pin 4 is mounted on the first rod 1, and the straight groove 22 is formed on the second rod 2, so that the relative movement of the two rods can be realized, and the two rods can not be separated from each other, and can also be rotated relatively.
In one embodiment, as shown in fig. 3, the sheath 3 is fixed in position along the length of the first pin 1. The end of the second rod 2 enters the sheath 3 during the approach of the first rod 1.
In another embodiment, as shown in fig. 4, the sheath 3 can slide in the length direction of the first rod 1, the first rod 1 is provided with a limiting portion 11 for limiting the movement position of the sheath 3, the sheath 3 can only move from the limiting portion 11 to the direction away from the second rod 2, and when the limiting portion 11 limits the position of the sheath 3 so that the two rods are in a fixed state, the second rod 2 cannot drive the sheath 3 to move along the length direction of the first rod 1, so as to achieve relative fixation. In this embodiment, when the second rod 2 is in a foldable state relative to the first rod 1 and a user needs to fix the second rod 2 relative to the first rod 1, the sheath 3 can be fixed to the end of the second rod 2 after the second rod 2 is fed to the first rod 1.
In both embodiments, the fixing manner of the sheath 3 and the second rod 2 may be: the sleeve body 3 is internally provided with an internal thread 31, the end part of the second rod piece 2 is provided with an external thread 21 matched with the internal thread 31, in the fixing mode, the sleeve body 3 can rotate relative to the first rod piece 1, and the internal thread 31 in the sleeve body 3 can be matched with the external thread at the end part of the second rod piece 2 by rotating the sleeve body 3.
The utility model discloses a collapsible automobile-used plug-in folding mechanism can be for the second member of first member plug through setting up to the setting can make the cover body of both relatively fixed, can realize the convenient switching of relative state between the two parts automobile body on the collapsible car, and simple structure is compact, and can not be because the mistake touches unexpected unblock in the use, and the security is high.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
