[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1-Figure 3 ,in, Figure 1A structural schematic diagram of a preferred embodiment of a slide rail mechanism for a car seat provided by the utility model; Figure 2 for Figure 1 The enlarged structural diagram of point A is shown;

[0021] Figure 3 for Figure 1 The schematic diagram of the internal cross-sectional structure of the positioning cylinder shown. A slide rail mechanism for a car seat comprises two positioning seats 1, the inner walls of the two positioning seats 1 opposite to each other are fixed with positioning rails 2, and the number of the positioning rails 2 is two, the outer sides of the two positioning rails 2 are slidably mounted with a sliding frame 5, the sliding frame 5 slides forward and backward along the inner horizontal direction of the two positioning seats 1 through the two positioning rails 2, the upper surfaces of the sliding frame 5 are fixed with positioning blocks 8 on both sides, the outer walls of the two positioning blocks 8 are fixed with rotating shafts 7, the outer sides of the two positioning blocks 8 are rotatably mounted with swing frames 9 through two rotating shafts 7, and the upper surfaces of the swing frames 9 are slidably mounted with auxiliary columns 14 on both sides;

[0022] After the user fixes the two positioning seats 1 at appropriate positions inside the car, the user can install the seat on top of the seat frame 6. Thereafter, when the user needs to adjust the seat position, the user can hold the auxiliary column 14 with both hands, and then press the auxiliary column 14 downward to adjust the position of the seat forward and backward. The auxiliary column 14 allows users with lumbar injuries to adjust the front and rear positions of the seat without bending over, and the user can also adjust the height of the two auxiliary columns 14 by loosening the knobs 11 on both sides of the swing frame 9 so that users of different heights can adjust the front and rear positions of the seat.

[0023] The outer walls of both sides of the swing frame 9 are threadedly connected with knobs 11, and the upper surfaces of the two positioning slide rails 2 are evenly spaced with positioning holes 3;

[0024] The user can slide and adjust the height of the auxiliary column 14 by loosening the knob 11 , and after adjusting to a suitable height, the user can tighten the knob 11 to fix the position of the auxiliary column 14 .

[0025] Positioning cylinders 10 are fixed on both sides of the upper surface of the sliding frame 5 and on the sides of the two positioning blocks 8, and springs 12 are fixed on the top of the inner walls of the two positioning cylinders 10;

[0026] The spring 12 can give the limit block 13 a downward elastic force when the user releases the auxiliary column 14 , and the limit block 13 is inserted downward into the positioning hole 3 by the elastic force of the spring 12 to fix the position of the sliding frame 5 .

[0027] Limiting blocks 13 are placed inside the two positioning cylinders 10 and below the springs 12. One end of each side of the swing frame 9 is respectively engaged with the outer walls of the two limiting blocks 13. When the swing frame 9 is pressed down, it will squeeze the spring 12 upwards through the engagement with the two limiting blocks 13.

[0028] Press the auxiliary column 14 downward. When the auxiliary column 14 is pressed downward, the swing frame 9 located inside the positioning tube 10 will be tilted up, driving the limit block 13 to press the spring 12 upward. At this time, the user can slide and adjust the position of the sliding frame 5 to achieve the effect of adjusting the front and rear position of the seat. After adjusting to the appropriate position, the user releases the auxiliary column 14, and then shakes the seat back and forth. The limit block 13 will be inserted downward into the positioning hole 3 through the elastic force of the spring 12, thereby fixing the position of the sliding frame 5.

[0029] Shock-absorbing rubber pads 4 are fixed on both sides of the inner wall of the two positioning seats 1 on opposite sides and on the outside of both sides of the two positioning slide rails 2;

[0030] When the sliding frame 5 slides to the inner walls of the two positioning seats 1 , the shock-absorbing rubber pad 4 can provide a shock-absorbing effect when the sliding frame 5 contacts the positioning seats 1 .

[0031] A seat frame 6 is fixed on the upper surface of the sliding frame 5 and on the side of the swing frame 9 .

[0032] The working principle of a slide rail mechanism for a car seat provided by the utility model is as follows:

[0033] After the user fixes the two positioning seats 1 at the appropriate positions inside the car, the user can install the seat above the seat frame 6. Thereafter, when the user needs to adjust the seat position, the user can hold the auxiliary column 14 with both hands, and then press the auxiliary column 14 downward. When the auxiliary column 14 is pressed downward, the swing frame 9 located inside the positioning cylinder 10 will be tilted up, driving the limit block 13 to squeeze the spring 12 upward. At this time, the user can slide and adjust the position of the sliding frame 5 to achieve the effect of adjusting the front and rear position of the seat. After adjusting to the appropriate position, the user releases the auxiliary column 14, and then shakes the seat limit block 13 back and forth, and the seat limit block 13 will be inserted downward into the positioning hole 3 through the elastic force of the spring 12, thereby fixing the position of the sliding frame 5.

[0034] Compared with the related art, the slide rail mechanism for a car seat provided by the utility model has the following advantages:

[0035] Beneficial effects:

[0036] After the user fixes the two positioning seats 1 at appropriate positions inside the car, the user can install the seat on top of the seat frame 6. Thereafter, when the user needs to adjust the seat position, the user can hold the auxiliary column 14 with both hands, and then press the auxiliary column 14 downward to adjust the position of the seat forward and backward. The auxiliary column 14 allows users with lumbar injuries to adjust the front and rear positions of the seat without bending over, and the user can also adjust the height of the two auxiliary columns 14 by loosening the knobs 11 on both sides of the swing frame 9 so that users of different heights can adjust the front and rear positions of the seat.
