Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a self-rescue escaping device for an automobile, which is convenient to mount and carry, comprises a disc 1, wherein the front surface of the disc 1 is in threaded connection with a fixing nut 2, the disc 1 can be fixed on a rim of a wheel 12 through the fixing nut 2, one end of an upper supporting column 3 is fixedly connected to the outer part of the disc 1, two sides of the bottom of the upper supporting column 3 are provided with grooves, the middle part of the upper supporting column 3 is provided with a semicircular bulge, the other end of the upper supporting column 3 is rotatably connected with a lower supporting column 4, one side of the lower supporting column 4, which is far away from the upper supporting column 3, is in a circular truncated cone shape, the lower supporting column can be better embedded into a muddy road surface, the friction force between the wheel 12 and the ground when rotating is increased, two sides of the bottom of the lower supporting column 4 are provided with semicircular bulges, the middle part of the, go up the outside of support column 3 and cup jointed thread bush 6, 6 downwardly rotating of thread bush can cover the junction of last support column 3 and bottom suspension mast 4 completely, it is fixed with both, go up the positive bottom of support column 3 and the positive top of bottom suspension mast 4 and seted up through-hole 7, it has connecting axle 8 to peg graft in the through-hole 7, circular slot 9 has been seted up to the bottom of going up support column 3 and the top of bottom suspension mast 4, the top and the bottom fixedly connected with connecting block 10 of circular slot 9, fixedly connected with arc spring 11 between two connecting blocks 10, go up support column 3 and bottom suspension mast 4 when being located same straight line, arc spring 11 is in compression state, arc spring 11 is when not being in balanced state by exogenic action, bottom suspension mast 4 is in right pivoted state, can occupy littleer space, and convenient to carry, the back fixedly connected with wheel 12 of disc 1.

The working principle is as follows: when the wheel 12 falls into a muddy road and slips in place, the disc 1 is fixed on a rim of the slipped wheel 12 by the fixing nut 2, the thread bushing 6 is rotated in the direction far away from the disc 1, the lower support column 4 which is straightened and does not contact with the muddy road is straightened and fixed, then the automobile is started to step on the accelerator, when the lower support column 4 which is straightened and fixed is contacted with the muddy ground, the remaining lower support column 4 is straightened and fixed by the thread bushing 6, the trap is completely arranged, the automobile accelerator is stepped on, the round platform-shaped bottom of the lower support column 4 is embedded into the muddy ground, the friction force with the ground is increased during rotation and does not slip, so that the wheel 12 is driven out of the muddy road, after the use is finished, the thread bushing 6 is rotated to the position where the upper support column 3 is close to the disc 1, the arc-shaped spring 11 in the circular groove 9 gives downward elasticity to the lower support column 4, the lower support column 4 is rotated to the right about the rotation axis 8 and then the fixing nut 2 on the disc 1 is removed.

To sum up, this car ware of getting rid of poverty of saving oneself convenient to installation is carried through fixing disc 1 on the rim of wheel 12, straightens the back through thread bush 6 earlier and does not straighten fixedly with the bottom suspension dagger 4 of muddy ground contact, starts the car and steps on the car throttle, when straightening fixed bottom suspension dagger 4 and muddy ground contact, rethread thread bush 6 straightens remaining bottom suspension dagger 4 fixed to reached and need not jack up the effect that just can install the ware of getting rid of poverty with wheel 12.

Through turning to the position that the upper support column 3 is close to disc 1 with thread bush 6, arc spring 11 in the circular slot 9 gives 4 decurrent elasticity of lower support column, and lower support column 4 can rotate right around axis of rotation 8 to reached automatic effect of withdrawing, portable, application scope is more extensive.

Having shown and described embodiments of the present invention, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
