Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in the figures 1-10, a steering column convenient for replacing a steering wheel comprises a steering column 10, a steering wheel 11 and a steering wheel cover 12, one end of the steering column 10 is arranged as an opening, two clamping rotating shafts 15 are rotationally connected in the steering column 10, a torsion spring is fixedly connected between each clamping rotating shaft 15 and the steering column 10, a clamping block 14 is sleeved on the part of each clamping rotating shaft 15, which is positioned at the opening of the steering column 10, the section of each clamping block 14, which is perpendicular to the central line of the clamping rotating shaft 15, is semicircular, the circumferential side of each clamping block 14 is arranged in a ladder shape, the ladder edge angle of each clamping block 14 is arranged in a fillet shape, two abutting planes are further arranged on the outer circumferential side of the opening of the steering column 10, two sliding grooves penetrating through the steering column 10 are arranged on the abutting planes of the steering column 10, the two sliding grooves are symmetrically arranged about the central line of the steering column 10, and a compression bar 18 is slidably connected in each sliding groove, a spring is arranged between the inner wall of each sliding groove far away from the opening side of the direction column 10 and the pressing rod 18, a limiting shaft 19 is arranged between the end surface of one side of each pressing rod 18 far away from the spring and the clamping block 14, and the limiting shaft 19 can slide in the direction column 10 and the clamping block 14.

Still be equipped with the detaching module in the direction post 10, the detaching module is including pivot 16 that resets, pivot 16 that resets sets up in direction post 10 central line department, 16 one side of pivot that resets extends to in the opening and can be at the internal rotation of direction post 10, the 15 sides of screens axis of rotation of keeping away from of pivot 16 that resets have linked firmly connecting rod 17, connecting rod 17 perpendicular to pivot 16 that resets, connecting rod 17 extends to the external world to keeping away from 16 sides of pivot that resets, the external part of connecting rod 17 links firmly the reset ring cover 13 of cover on direction post 10, connecting rod 17 turned angle is greater than 90 and is less than 180.

When the steering wheel is required to be installed, the hollow part of the steering wheel 11 is directly pressed downwards along the abutting plane on the steering column 10 to the side far away from the opening of the steering column 10, when the steering wheel 11 is abutted against the pressure lever 18 and then is continuously pressed down against the elastic force of the spring until the pressure lever 18 drives the limit shaft 19 to be separated from the limit stop block 14, at the moment, because the torsion spring is in a power storage state, therefore, the position clamping block 14 is rotated outwards to be opened under the action of the elasticity of the torsion spring, the steering wheel 11 is clamped at the step part of the position clamping block 14, then the steering wheel cover 12 is buckled after the corresponding line is installed, and at this time, the installation is finished, because 14 steps of screens piece set up, through the planar difference in height of ladder, make the steering wheel of the different models of cooperation that it can be better, the fillet setting of screens piece 14 makes its cooperation inseparabler, and further fillet setting also can make the steering wheel excessively cooperate, avoids the phenomenon that drops to appear after its long-time use.

When the steering wheel 11 needs to be disassembled, the steering wheel cover 12 is taken out firstly, then a corresponding circuit is disconnected, the reset ring sleeve 13 is rotated, the reset ring sleeve 13 drives the reset rotating shaft 16 to rotate through the connecting rod 17, the reset rotating shaft 16 rotates to drive the clamping rotating shaft 15 to overcome the torsion of the torsion spring to rotate inwards through the pull rope, so that the clamping block 14 is separated from the clamping position of the steering wheel 11, after the limiting groove in the clamping block 14 corresponds to the limiting shaft 19, the limiting shaft 19 enters the limiting groove of the clamping block 14 under the elastic force of the spring to limit the rotation of the clamping block 14, the steering wheel 11 can be directly taken down at the moment to be replaced, and through the arrangement of the abutting plane, on one hand, the installation and disassembly processes of the steering wheel 11 are more convenient, the steering wheel deflection generated during installation is avoided, and on the other hand, because of the tight fit of the abutting plane, the steering wheel cannot be loosened during use.

It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
