Detailed Description

The essential features and advantages of the invention will be further described below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to fig. 4, the crankshaft and box combination device of the present embodiment includes a box 1, a mounting bracket 2 and a connecting assembly 3, wherein the box 1 is connected to the mounting bracket 2 through the connecting assembly 3. Coupling assembling 3 includes base 4 and top cap 5, be equipped with spliced pole 6 on the top cap 5, spliced pole 6 is connected through knob portion 7 with top cap 5. The top cover 5 has a recess 51, a support plate 52 is disposed within the recess 51, the support plate 52 is vertically disposed, a plurality of support plates 52 are spaced around the recess 51, and a free end 521 of the support plates 52 extends out of the annular wall 53 of the top cover 5. The base 4 is made of an elastic material, the base 4 is provided with a notch 41, and the support plate 52 is inserted in the notch 41. Among the above-mentioned technical scheme, mounting bracket 2 and automobile body fixed connection, box 1 passes through coupling assembling 3 to be fixed on mounting bracket 2. The position of the connecting column 6 can be adjusted by arranging the knob part 7, so that the position of the box body 1 is adjusted. The top cover 5 can be positioned by combining the support plate 52 with the cutout 41, and is prevented from shaking. Because the base 4 is made of elastic material, when receiving vibration, the base can buffer the vibration and reduce the vibration to be transmitted to the frame, and the base 4 of the embodiment is made of rubber material. By the technical scheme, the box body can be conveniently assembled with the mounting frame, and the box body is convenient to mount; in addition, the vibration transmission generated by the operation of the box body can be reduced.

In this embodiment, an external thread 71 is disposed on an outer side of the knob portion 7, an internal thread 541 is disposed in the mounting hole 54 of the top cover 5, and the internal thread 541 is coupled with the external thread 71. Through the technical scheme, the knob part 7 can move relative to the top cover after rotating, so that the height of the knob part 7 is adjusted, and the position of the box body 1 is adjusted. And a fixing nut 8 is arranged below the knob part 7, and the fixing nut 8 is in threaded connection with the knob part 7, so that the connection is more stable.

In this embodiment, the connecting column 6 is a screw, and the connecting column 6 is vertically arranged, so that the box body and the connecting column can be conveniently assembled.
