[0025] This utility model features a floor support installation positioning plate, as shown in the example. Figures 1 to 3 As shown, the floor support and seat rail positioning at S15 Y953 consists of a positioning plate 1, a stop block 2, a locking bolt 3, and a positioning pin 4.

[0026] The positioning plate 1 is a T-shaped plate, with a long horizontal plate and a short vertical plate. A step 13 is provided on the positioning plate 1, and positioning holes 11 and mounting holes 12 are distributed on the step 13. The step ensures the relative position between the upper surface of the seat guide rail and the upper surface of the floor support. Two stop blocks 2 are symmetrically fixed to the positioning plate 1 by locking bolts 3 and positioning pins 4. In use, clamping pliers are used to connect the floor support mounting positioning plate and the seat guide rail to the floor support, satisfying the relative position requirements between the floor support and the seat guide rail. The stop blocks on the positioning plate ensure the spacing between the seat guide rail and the floor support.

[0027] Figure 4 and 5 As shown, the positioning plate is a T-shaped aluminum plate with a length of 167±0.1mm. The horizontal plate of the T-shaped aluminum plate is 170mm long and is a long plate. The vertical plate of the T-shaped aluminum plate is 135mm long. Step 13 is set on the long plate, with the same length as the long plate and the same thickness as the vertical plate, which is 13mm. The width of the step is 10.8mm and the height is 3±0.1mm.

[0028] Two positioning holes 11 and two mounting holes are located on the step 13. The two positioning holes 11 are symmetrical to the center line of the longitudinal plate, and the distance between the two positioning holes is 38mm. The two mounting holes 12 are located outside the positioning holes 11, and the distance between the two mounting holes 12 is 57.6mm.

[0029] Stop block structure as follows Figure 6 and 7 As shown, the block has a countersunk through hole 22 and a pin hole 21. The countersunk through hole 22 corresponds to the mounting hole 12 on the positioning plate 1 and is locked in place by a locking bolt 3. The pin hole 21 corresponds to the positioning hole 11 on the positioning plate 1 and is positioned by a positioning pin 4. The thickness of the stop block is 7mm.
