[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] The present application discloses a liftable tricycle seat cushion. Figure 1-Figure 3A liftable tricycle seat cushion comprises a wooden base plate 1, on which a plurality of U-shaped fastening blocks 6 are fixed, and a hand-tightening bolt 8 is screwed on the U-shaped fastening block 6; it also comprises a buffer mechanism and a fixing mechanism; the buffer mechanism is installed on the top of the wooden base plate 1, and is connected to the fixing mechanism; the buffer mechanism is used for buffering and shock absorption, and the fixing mechanism is used to fix the buffer mechanism on the wooden base plate 1, the buffer mechanism comprises an isolation pad 10 and a buffer pad 9 fixed on the top of the wooden base plate 1, the buffer pad 9 is located on the top of the isolation pad 10, a plurality of Velcro 11 are sewn and fixed on the isolation pad 10, and the buffer pad 9 is bonded and fixed on the Velcro 11, the fixing mechanism comprises a covering leather layer 2 and a tightening belt 3 sleeved on the buffer pad 9, the covering leather layer 2 semi-surrounds the buffer pad 9, the tightening belt 3 covers the top of the covering leather layer 2, and the two ends of the tightening belt 3 respectively pass through the U-shaped fastening block 6 and are fixed by the hand-tightening bolt 8.

[0021] When disassembling, the hand-tightening bolts 8 are successively turned counterclockwise to prevent the tightening belt 3 from being squeezed, and then the tightening belts 3 are pulled out respectively. At this time, the upper and lower covering cortexes 2 can be pulled out, and the buffer pads 9 are exposed to the outside. Then the damaged buffer pads 9 can be uncovered and replaced with new ones. By setting the U-shaped fastening block 6, the covering cortex 2, the tightening belt 3, and the hand-tightening bolts 8, when the internal buffer pad 9 is damaged, the setting is convenient for the user to purchase a replacement buffer pad 9 and replace it by himself. It is only necessary to release the fixation of the hand-tightening bolts 8, pull out the tightening belt 3 and remove the covering cortex 2 to remove the buffer pad 9. The operation is simple and easy to use. By setting the isolation pad 10, the problem of traditional buffer 9 pads directly contacting the wooden base plate 1 and causing severe wear is avoided, the service life of the buffer pad 9 is extended, and the practicality is improved.

[0022] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of No. 1 anti-slip grooves 4 are arranged on the top of the covering leather layer 2, and protrusions 7 are fixed at both ends of the tightening belt 3. The protrusions 7 can prevent the tightening belt 3 from accidentally detaching from the U-shaped fastening block 6, and have a limiting effect.

[0023] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of limiting stripes 5 are provided on the top of the covering leather layer 2, and the limiting stripes 5 are located on both sides of the tightening belt 3, and are used to limit and fix the tightening belt 3. Between the two limiting stripes 5 on the tightening belt 3, the user can quickly position the tightening belt 3 during installation, which facilitates the installation operation and improves convenience.

[0024] In this embodiment, if Figure 2 and Figure 3As shown, a plurality of No. 2 anti-skid patterns 12 are provided on both ends of the tightening belt 3, and the No. 2 anti-skid patterns 12 are connected to the hand-tightening bolts 8. When the hand-tightening bolts 8 are pressed on the No. 2 anti-skid patterns 12, the No. 2 anti-skid patterns 12 will be squeezed and deformed, thereby increasing friction and improving stability.

[0025] The implementation principle of the liftable tricycle seat cushion of the embodiment of the present application is as follows: when disassembling, the hand-tightening bolts 8 are successively screwed counterclockwise to prevent the tightening belt 3 from being squeezed, and then the tightening belts 3 are respectively pulled out. At this time, the upper and lower covering cortexes 2 can be pulled out, and the buffer pad 9 is exposed to the outside. Then the damaged buffer pad 9 can be uncovered and replaced with a new one. By setting a U-shaped fastening block 6, a covering cortex 2, a tightening belt 3, and a hand-tightening bolt 8, when the internal buffer pad 9 is damaged, the setting is convenient for users to purchase a replacement buffer pad 9 and replace it by themselves. Only the fixation of the hand-tightening bolt 8 is released, the tightening belt 3 is pulled out, and the covering cortex 2 is removed to remove the buffer pad 9. The operation is simple and easy to use. By setting an isolation pad 10, the problem of traditional buffer 9 directly contacting the wooden base plate 1 and causing severe wear is avoided, the service life of the buffer pad 9 is extended, and the practicality is improved.
