The seat assembly 400 includes a mounting frame 410, a seat cushion 420, and a backrest 430. The mounting frame 410 is fixedly mounted on one end of the top surface of the movable plate 200. The seat cushion 420 is fixedly mounted on the side of the mounting frame 410 away from the movable plate 200. The side of the mounting frame 410 facing the movable plate 200 is rotatably connected to one end of the backrest 430. The second telescopic component 500 includes a first sleeve 510 and a second sleeve 520. The second sleeve 520 is slidably installed inside the first sleeve 510 along the extending direction of the first sleeve 510. The top end of the first sleeve 510 is rotatably connected to the middle of the bottom surface of the backrest 430. The bottom end of the second sleeve 520 is rotatably connected to the movable plate 200. A second telescopic device 530 is provided inside the second sleeve 520 along the extending direction of the second sleeve 520. The two ends of the second telescopic device 530 are rotatably connected to the inner walls of the ends of the first sleeve 510 and the second sleeve 520, respectively. A second locking component 600 is provided on the outer wall of the first sleeve 510.

[0030] This invention involves placing the base 100 on the ground or a base surface. The first locking assembly 300 unlocks the movable plate 200 from the base 100. Then, the telescopic end of the first telescopic device 210 moves the movable plate 200 on the base 100. After the movable plate 200 reaches a suitable position, the first locking assembly 300 fixes it to the base 100. The second locking assembly 600 unlocks the first sleeve 510 and the second sleeve 520. Then, the second telescopic device 530 moves the first sleeve 510 along the second sleeve 520, using the first sleeve 510 to raise and lower the end of the backrest 430, adjusting the angle of the backrest 430. Finally, the second locking assembly 600 fixes the first sleeve 510 and the second sleeve 520. This invention simplifies the operation process of adjusting the seat position and angle, reduces the difficulty of adjustment, and increases the speed of seat adjustment, making it suitable for fitness enthusiasts.
[0031] Please see Figure 3 In one example of the adjustable seat device for fitness equipment of this utility model, the top of the base 100 is provided with two parallel guide rails 110 along the extending direction of the base 100. The moving plate 200 is slidably mounted on the two guide rails 110. The first locking component 300 cooperates with one of the guide rails 110. The first locking component 300 includes a first control rod 310 and a first connecting plate 320. One end of the first connecting plate 320 is rotatably mounted on the top of the moving plate 200 through a first rotating shaft 330. One end of the first control rod 310 is fixedly connected to the first rotating shaft 330. The other end of the first connecting plate 320 is provided with a first locking rod 340 facing the side of the moving plate 200. The moving plate 200 is provided with a third sleeve 350 that cooperates with the first locking rod 340. The bottom of the first locking rod 340 is elastically connected to the top of the third sleeve 350 through a first spring. One of the guide rails 110 is provided with a plurality of first insertion holes 360 that cooperate with the first locking rod 340. Each guide rail 110 has a limiting block 120 at both ends. When controlling the first locking assembly 300, pulling the first control lever 310 drives the first rotating shaft 330 to rotate. The first rotating shaft 330 drives the first connecting plate 320 to lift upward. The first connecting plate 320 drives the first locking lever 340 to move upward, causing the first locking lever 340 to disengage from the first insertion hole 360, thus unlocking the moving plate 200 from the base 100. After adjustment, releasing the first control lever 310 allows the first locking lever 340 to insert into the corresponding first insertion hole 360 under the action of the first spring, thus fixing the moving plate 200.
[0032] Please see Figure 5In one example of the adjustable seat device for fitness equipment of this utility model, a seat cushion bracket 421 is provided on one side of the top of the mounting frame 410, and the seat cushion 420 is fixedly installed on the top of the seat cushion bracket 421. A backrest bracket 431 is provided at the bottom of the backrest 430, one end of the backrest bracket 431 is rotatably connected to the top of the mounting frame 410, the top end of the first sleeve 510 is rotatably connected to the middle of the bottom surface of the backrest bracket 431, and a sleeve bracket 220 is provided at one end of the moving plate 200 facing the second telescopic component 600, and the bottom end of the second sleeve 520 is rotatably connected to the sleeve bracket 220.
[0033] Please see Figure 4 and Figure 6 In one example of the adjustable seat device for fitness equipment of this utility model, the second locking component 600 includes a fourth sleeve 610, which is fixedly installed on the outer wall of the first sleeve 510. A second locking rod 620 is slidably installed inside the fourth sleeve 610. One end of the second locking rod 620 facing the second sleeve 520 is elastically connected to the end of the fourth sleeve 610 away from the first sleeve 510 by a second spring. The second sleeve 520 is provided with a plurality of second insertion holes that cooperate with the second locking rod 620. The second locking assembly 600 further includes a second control rod 630. A second control box 640 is provided on the movable plate 200. The second control rod 630 is inserted into the second control box 640 and is rotatably connected to the second control box 640. The second control rod 630 is connected to the end of the second locking rod 620 away from the second sleeve 520 via a steel wire rope 660. A protective assembly 670 is sleeved on the outside of the steel wire rope 660. A limiting rod 650 is provided inside the second control box 640. The limiting rod 650 is located above the second control rod 630 and cooperates with the second control rod 630. When controlling the second locking assembly 600, pulling the second control lever 630 causes the wire rope 660 to move. The wire rope 660 then moves the second locking lever 620 along the fourth sleeve 610, causing the second locking lever 620 to disengage from the second insertion hole. This releases the lock between the first sleeve 510 and the second sleeve 520. After adjustment, releasing the second control lever 630 allows the second locking lever 620 to insert into the corresponding second insertion hole under the action of the second spring, thus securing the first sleeve 510 and the second sleeve 520. The limit lever 650 is used to limit the movement of the second control lever 630. The protective assembly 670 can be a rubber hose or similar component used to protect the wire rope 660 and prevent it from being exposed.
[0034] Please see Figure 7In one example of the adjustable seat device for fitness equipment of this utility model, a clamping assembly 540 is fixedly installed on the inner wall of the first sleeve 510, and the clamping assembly 540 is slidably connected to the outer wall of the second sleeve 520. The clamping assembly 540 is located between the first sleeve 510 and the second sleeve 520 to fill the gap, making the first sleeve 510 and the second sleeve 520 more stable and the sliding smoother, and also preventing wear on the first sleeve 510 and the second sleeve 520.
[0035] Please see Figure 5 In one example of the adjustable seat device for fitness equipment of this utility model, a support rod 230 is provided on the movable plate 200, and a support block 240 is provided on the top of the support rod 230. The support block 240 cooperates with the bottom surface of the backrest 430. The first telescopic device 210 and the second telescopic device 530 are both cylinders. Several rubber pads are provided on the bottom surface of the base 100. The support rod 230 and the support block 240 are used to limit and support the backrest 430.
