As shown in fig. 1 to fig. 5, the working principle of the adjustable pothole protection structure provided by the embodiment is as follows:
during normal use, installation axle 21 is in the normal state of screwing up, locking axle 2213 passes first locating hole 231, pass locking axle 2213 and adjusting shaft sleeve 2214 round hole in proper order through the bulb fitting pin, the Y of bulb fitting pin is to the freedom of movement and the X is to the draw-in groove restriction of adjusting shaft sleeve 2214 to the freedom of rotation, X is to the freedom of movement and the Y is to the freedom of rotation by the bayonet socket round hole restriction of adjusting shaft sleeve 2214, Z is to the freedom of movement by bulb fitting pin self structural limitation, namely the bulb fitting pin can only be followed Z and is rotated. Under the action of the ball locking pin, 6 degrees of freedom of the locking shaft 2213 are completely limited, at the moment, the locking shaft 2213 and the mounting shaft 21 act simultaneously, and 6 degrees of freedom of the whole pothole protection mechanism are completely limited and are in an open state.
When the ball locking pin needs to be replaced to the retracted state, the button of the ball locking pin is pressed, locking is released, the steel ball is retracted into the ball locking pin, the ball locking pin can be pulled out at the moment, and the limitation of the degree of freedom of the locking shaft 2213 is released. The installation axle 21 still is the normal state of screwing up, rotates whole pot hole protection mechanism under the effect of bearing 2212, until locking axle 2213 can pass second locating hole 241, and rethread bulb fitting pin locking (theory of operation is the same above), changes the state of packing up this moment for more.
When the pothole protection mechanism cannot be used continuously due to falling or collision, the whole mechanism can be replaced quickly by unscrewing the nut on the mounting shaft 21.
The adjustable pothole protection architecture that this embodiment provided compares in prior art, adopts chassis and adjustment mechanism, and adjustment mechanism includes installation axle and pothole protection subassembly, and the hole protection subassembly rotates around the installation axle in order to open or pack up adjustment mechanism to can adjust two kinds of states, be open state (normality) during normal use, if when meeting the unable obstacle that passes through of complicated topography, can change to packing up the state through adjustment mechanism, wait to pass through adjustment mechanism again behind the obstacle and change into the normality. The structure is positioned by two points of a locking shaft and an installation shaft, the installation shaft is fixed by a threaded nut, and the locking shaft is fixed by a ball locking pin; the installation position of the locking shaft is changed by rotating the locking shaft around the installation shaft, so that the switching of two different states of the pit protection mechanism is achieved. The adjustable pit protection structure provided by the embodiment is convenient to replace and maintain; the trafficability characteristic in a complex use place is high, and the adaptability is strong.
