Detailed description of the invention
Describe the technical solution of the utility model in detail below by way of embodiment, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
As shown in Figures 5 to 7, this patent provides a kind of light card steering column front-and-back adjusting device, includes lock bolt 21, regulates handle 22, jam nut (not shown), mobile screw 24, rail brackets 25, traversing carriage 61 and protective cradle 26;
Be prior art in the structure of the lock bolt 21 of the application, jam nut, mobile screw 24 and protective cradle 26 not improve, therefore, be not described in detail.
Described traversing carriage 61 is fixedly connected with described protective cradle 26; Described rail brackets 25, described traversing carriage 61 and described protective cradle 26 are U-shaped support; Wherein, the opening of traversing carriage 61 and the opening of rail brackets 25 are oppositely arranged, and traversing carriage 61 is arranged in the opening of rail brackets 25; The U-shaped opening upwards of protective cradle 26, upwards referring to herein is vertical with the U-shaped opening of rail brackets 25.In other embodiment of the application, the opening of protective cradle 26 also can be downward.
The first side 251 of described rail brackets 25 is provided with the first guide rail hole 253, and second side 252 is provided with the second guide rail hole 254; Shape and the size of described first guide rail hole 253 and described second guide rail hole 254 are all identical; Described first guide rail hole 253 is waist shaped hole.The first side wall 611 of described traversing carriage 61 is provided with the first perforation 615, second sidewall 612 and is provided with the second perforation 614; Shape, the size of the first perforation 615 and the second perforation 614 are all identical, and in the present embodiment, the first perforation 615 and the second perforation 614 are circular port.
