DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 2-Figure 4 As shown, in the present embodiment, a farm vehicle seat with an anti-collapse function comprises a backrest 1 and a base 4, the backrest 1 is fixedly arranged on the rear side of the base 4, telescopic rods 6 are fixed at the four corners of the upper end of the base 4, a buffer spring 5 is mounted on the outer side of the telescopic rod 6, the upper part of the telescopic rod 6 is fixedly arranged on the lower end of the buffer pad 3, a seat cushion 2 is clamped on the upper side of the buffer pad 3, a slide rod 9 is slidably connected inside the backrest 1, a connecting plate 11 is integrally formed at the rear part of the buffer pad 3, an adjusting rod 7 is fixedly arranged at the bottom of the backrest 1, the adjusting rod 7 passes through the connecting plate 11 and the slide rod 9 in turn, extends to the upper part of the slide rod 9 and is threadedly connected with a nut, and an adjusting spring 10 is mounted on the adjusting rod 7 on the upper and lower sides of the connecting plate 11.

[0022] like Figure 2 and Figure 3 As shown, there are slide grooves on the left and right sides of the inner wall of the backrest 1, and sliders 8 are fixed on the left and right ends of the slide rod 9. The sliders 8 are slidably connected in the slide grooves. The sliders 8 and the slide grooves ensure that the slide rod 9 can move normally and stably. There are two groups of adjusting rods 7 and nuts, and the two groups of adjusting rods 7 and nuts are symmetrically installed on the inner side of the backrest 1 to ensure the stable force of the connecting plate 11. The top of the adjusting rod 7 is processed with threads, and the threads are convenient for the nut to be installed and rotated, thereby facilitating the limiting of the slide rod 9.

[0023] like Figure 4 As shown, the cross-section of the base 4 is rectangular when viewed from above, and fixing holes are provided on all sides of the base 4. The fixing holes can be used to facilitate the cooperation with external bolts 17 to fix it to the driving position. Limit rods 13 are fixed on the left and right sides of the lower end of the buffer pad 3, and hanging rings 12 are connected to the left and right sides of the seat cushion 2 through elastic ropes. The hanging rings 12 are mounted on the limiting rods 13. By mounting the hanging rings 12 on the limiting rods 13, the seat cushion 2 can be limited to avoid left and right movement.

[0024] like Figure 2 and Figure 4As shown, a groove is provided in the middle of the buffer pad 3, and a protrusion is integrally formed at the bottom of the seat cushion 2, which is snapped into the groove. A number of ventilation holes are provided on the buffer pad 3 and the seat cushion 2. The seat cushion 2 can be limited by the protrusion and the groove to prevent movement during riding, which would cause the seat cushion 2 to move and easily fall off.

[0025] like Figure 4 As shown, two groups of clips 16 are symmetrically fixed to the lower end of the buffer pad 3. The cross-section of the clip 16 is L-shaped when viewed from the side. A clip block 15 is clipped inside the clip 16. The clip block 15 is fixed to the side of the fan 14. A bolt 17 is threadedly connected to the lower side of the clip 16.
