The material of the bottom plate 162 can be a high-strength steel plate, and the surface thereof is subjected to phosphating treatment, so as to increase the adhesion and corrosion resistance.

[0048] In order to further improve the positioning accuracy, the movable shaft 152 is provided with a slot 153 extending in the height direction, the slot 153 is arranged on both sides of the movable shaft 152 and corresponds to the side plates 161 one by one, and the guide bolt 163 is arranged through the side plates 161 and the slots 153 and extends into the movable shaft 152. The length of the slot 153 can be changed according to actual conditions, so as to allow the movable shaft 152 to move up and down freely within a certain range and avoid being stuck. The material of the guide bolt 163 can be stainless steel or high-strength alloy steel, and the surface thereof is subjected to heat treatment, so as to increase the hardness and wear resistance.

[0049] As shown in FIG. 1, Figure 5 The positioning assembly 13 further includes an adjusting part 18, the movable shaft 152 is hollow inside and is provided with an elastic part 19, the adjusting part 18 is arranged at the lower end of the fixing base 16 and penetrates the bottom plate 162 upwards into the movable shaft 152 and abuts against one end of the elastic part 19, and the other end of the elastic part 19 abuts against the upper end of the movable shaft 152.

[0050] The adjusting part 18 further includes a nut 183, the nut 183 is sleeved with the adjusting bolt 181 and can lock the adjusting bolt 181. The material of the nut 183 can be stainless steel or copper alloy, and the surface thereof is subjected to nickel plating treatment, so as to increase the rust resistance and aesthetic degree.

[0051] The implementation principle of the embodiment is that when the board 11 moves horizontally on the base 12, one side of the positioning block 111 is in contact with the positioning wheel 14, and as the positioning block 111 continues to move, the positioning wheel 14 is abutted and drives the movable support 151 and the movable shaft 152 to move downward, the elastic member 19 in the movable shaft 152 is compressed, until the positioning wheel 14 reaches the middle part of the positioning block 111, at this time, the elastic member 19 moves upward and drives the movable shaft 152, the movable support 151 and the positioning wheel 14 to move upward, so that the positioning wheel 14 is fixed at the middle part of the positioning block 111, and the elastic member 19 is still in the compressed state, so that the reaction force can tightly press the positioning wheel 14 against the middle part of the positioning block 111, thereby achieving the positioning of the board 11, and preventing the inertia of the automobile from causing the board 11 to be easily shaken. When the board 11 needs to be moved, a very strong force is applied to the board 11 to enable the board 11 to move in the horizontal direction.

[0052] The adjusting bolt 181 can move the height of the elastic member 19, thereby controlling the size of the elastic force, so that the positioning wheel 14 and the positioning block 111 can be more tightly matched, and the positioning accuracy is improved; meanwhile, the nut 183 provided on the adjusting bolt 181 can lock the adjusting bolt 181, so as to prevent the adjusting bolt 181 from suddenly loosening, thereby affecting the cooperation between the positioning wheel 14 and the positioning block 111. The guide bolt 163 passes through the side plate 161 and the slot 153 into the movable shaft 152, thereby playing a guiding and limiting role on the movable shaft 152, the movable support 151 and the positioning wheel 14, preventing them from moving forward and backward and left and right, so that the movable shaft 152 can only drive the movable support and the positioning wheel 14 to move upward and downward. The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
