[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or may have an intervening element present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or may have an intervening element present. When an element is referred to as being "fixedly connected to" another element, it can be a common fixing connection method such as welding, bolting, or gluing.

[0029] Please refer to Figure 1-5A preferred embodiment of this utility model discloses a seat adjustment mechanism, including a base assembly 1 and a support frame 2; the base assembly 1 includes a rotating mechanism and a rotating locking mechanism for locking the rotating mechanism; the support frame 2 is slidably disposed on the top of the base assembly 1; a front and rear locking mechanism is provided on one side of the support frame 2 for locking the support frame 2.

[0030] Specifically, the base assembly 1 includes a base 101 and a movable frame; a mounting hole 102 is provided on one side of the base 101; the movable frame is disposed on the top of the base 101; the rotating mechanism includes a rotating nest 103; the rotating nest 103 is embedded in the base 101 from the bottom; an alignment hole is provided on one side of the rotating nest 103; the rotating locking mechanism includes a locking rod 105; the locking rod 105 is movably disposed on one side of the base; one end of the locking rod 105 movably passes through the mounting hole 102 and the alignment hole.

[0031] Specifically, a positioning frame is provided on one side of the rotating nest 103; a limiting plate 106 is provided inside the positioning frame; a limiting space is formed between the limiting plate 106 and the rotating nest 103; an insertion / removal hole 107 is provided on the limiting plate 106; the rotating locking mechanism also includes a handle 108 and a limiting head 109; the handle 108 is provided at one end of the locking rod 105; the locking rod 105 moves through the insertion / removal hole 107 and the limiting space and is inserted into the alignment hole; the limiting head 109 is provided at the other end of the locking rod 105; the limiting head 109 moves through the alignment hole; a limiting groove 110 is provided between the limiting head 109 and the locking rod 105.

[0032] Normally, the locking lever 105 is mounted in the mounting hole 102, the insertion hole 107, and the alignment hole. The limiting head 109 passes through the alignment hole and inserts into the corresponding structure on the seat, locking the rotating nest 103 to the seat. When the seat needs to be adjusted, hold the handle 108 and pull out the locking lever 105, then pull the limiting head 109 into the alignment hole to unlock the rotating nest 103. At this time, the base assembly 1 can be rotated to rotate the seat, making it convenient for people to sit or get up. Afterward, the seat can be rotated back to its original position to re-insert the limiting head 109 into the corresponding structure for locking. If the locking lever 105 is pulled out too far, for example, if the limiting head 109 is pulled out into the limiting space, the limiting head 109 loses its supporting force and falls downward, causing the limiting groove 110 to fall and get stuck on the outside of the insertion hole 107, preventing the locking lever 105 from falling off the base 101.

[0033] Specifically, the movable frame includes a movable plate 111 and a rotating shaft 112; the rotating shaft 112 is integrally disposed on the top of the base 101; the rotating shaft 112 is disposed in the middle of the movable plate 111; a reinforcing connecting plate 113 is provided between the rotating shaft 112 and the movable plate 111; the top of the rotating nest 103 is embedded in the rotating shaft 112. This utility model has high structural strength.

[0034] Specifically, the support frame 2 includes a guide frame 201 and a support plate 202; the guide frame 201 has a guide groove 203 on its inner side; the base assembly 1 includes a slide rail sleeve 113; the slide rail sleeve 113 is sleeved on both sides of the movable plate 111; the slide rail sleeve 113 is slidably disposed in the guide groove 203.

[0035] Specifically, the front and rear locking mechanism includes a fixed claw 114 and a limiting claw 204; the fixed claw 114 is disposed at the bottom of the moving plate 111; the limiting claw 204 is hinged to the bottom of the guide frame 201; part of the claw opening of the limiting claw 204 is movably misaligned and engaged with the claw opening of the fixed claw 114.

[0036] Specifically, the front and rear locking mechanism further includes a wrench 205, two fixing sleeves 206, and a torsion spring 207; one end of the wrench 205 is provided with a rotating rod 208; one side of the limiting claw 204 is provided with a limiting sleeve 209; the limiting sleeve 209 is sleeved on the outside of the rotating rod 208; the two fixing sleeves 206 are rotatably sleeved on both ends of the rotating rod 208; the two fixing sleeves 206 are respectively fixed to the bottom of both ends of the guide frame 201 by two bolts 210; the torsion spring 207 is sleeved on the outside of the rotating rod 208; one end of the torsion spring 207 is engaged with the outside of the guide frame 201.

[0037] When adjusting the seat's fore-and-aft position, hold the wrench 205 and rotate the lever 208 to separate the limiting pawl 204 from the fixing pawl 114. At this time, the seat can be pulled to move the support plate 202 and the guide frame 201 back and forth along the slide rail sleeve 113. When the position is properly adjusted, release the wrench, and the lever 208 will reset under the action of the torsion spring 207, and the limiting pawl 204 will re-engage and fix with the fixing pawl 114.

[0038] Specifically, the tops of the two bolts 210 pass through the guide groove 203 and are fixed inside the movable plate 111; the two bolts 210 respectively intercept both ends of the slide rail sleeve 113. While fixing the fixing sleeve 206, the bolts 210 also serve as limiting ends of the slide rail sleeve 113 to prevent the support frame 2 from falling off the base assembly 1.

[0039] Specifically, the seat adjustment mechanism also includes a seat tube 3; a locking hole 31 is provided on the side of the seat tube 3; the locking hole 31 can be directly aligned and fitted with the alignment hole; the rotating nest 103 is rotatably sleeved on the outside of the seat tube 3; the limiting head 109 moves through the alignment hole and inserts into the locking hole 31. The seat tube 3 is used to be installed on the seat to facilitate the rotation or locking of the rotating nest 103.

[0040] Specifically, the outer side of the seat tube 3 is provided with a positioning hole 32; the side wall of the rotating nest 203 is provided with a positioning opening 204; the base assembly 1 also includes a positioning glass bead 115; the positioning glass bead 115 is fixed to one side of the base 101; the round end of the positioning glass bead 115 passes through the positioning opening 204 and slides into the positioning hole 32.
