[0024] Example

[0025] Cooperate Figures 1 to 5 As shown, this utility model discloses a seat locking structure for a rowing machine. This structure is applied to a rowing machine, which has a slide rail 1, including a seat 2, a slide block 3, and a locking member 4. The seat 2 is slidably mounted on the slide rail 1 via the slide block 3. The slide block 3 has an inwardly facing locking wheel 31. The locking member 4 is rotatably mounted on the side wall of the slide rail 1. The locking member 4 has a locking slot 41. When the seat 2 and the slide block 3 slide along the slide rail 1 to the locking member 4, the locking member 4 is pushed to rotate clockwise by the locking wheel 31. After entering the locking slot 41, the locking member 4 resets and locks the locking wheel 31, restricting the movement of the slide block 3 and the seat 2.

[0026] The locking component 4 includes a mounting plate 42, a locking housing 43, an elastic element 44, and a screw 45. The slide rail 1 has a mounting hole 11 on its side wall. The mounting plate 32 is disposed in the mounting hole 11. The locking housing 43 has a mounting part 431 that is adapted to the mounting plate 42. The mounting part 431 and the mounting plate 42 have a rotating hole that aligns with the mounting hole 11. The elastic element 44 is installed in the mounting part 42. The screw 45 passes through the mounting part 431 and the mounting plate 42 from the outside to the inside and is threaded into the mounting hole 11 of the slide rail 1.

[0027] The mounting plate 42 is provided with at least two front limiting blocks 421 facing the locking housing 43. The two front limiting blocks 421 are symmetrically arranged. The mounting part 431 is provided with two limiting protrusions 432 on its inner wall. The elastic member 44 is provided with two protrusions 441 that are engaged with the two limiting protrusions 432 and two concave portions 442 that are engaged with the two front limiting blocks 421. When the locking housing 43 rotates, the limiting protrusions 432 squeeze the elastic member 44, the front limiting blocks 421 restrict the movement of the elastic member 44, and the elastic member 44 pushes the limiting protrusions 432 to drive the locking housing 43 to reset.

[0028] The slide rail 1 has a limiting hole 12 on one side of the mounting hole 11, and the mounting plate 42 has a limiting post 422 on the side facing the slide rail 1 that is inserted into the limiting hole 12.

[0029] The locking housing 43 is provided with an upwardly oriented hook-shaped part 433, which forms a locking structure. The outer side of the end of the hook-shaped part 433 is provided with an inclined surface. After the roller 31 of the slide block 3 abuts against the inclined surface, the roller 31 rolls along the inclined surface and pushes the locking housing 43 to rotate.

[0030] The slide block 3 is provided with two side frames 32 and two rollers 33. The two side frames 32 are located on both sides of the slide rail 1, and the two rollers 33 are located between the two side frames 32 and on the top of the slide rail 1. The bottom of the side frame 32 is provided with an opening, and the chuck 31 is rotatably installed in the opening by a screw and a nut.

[0031] The chuck 31 has two sets and is respectively installed on the two side frames 32. The locking member 4 has two sets and is provided on the two side walls of the slide rail 1.

[0032] The seat 2 is mounted on the two side frames 32 by screws.

[0033] In this embodiment, the sliding seat 3 on the rowing machine slide rail 1 is locked by the locking piece 4. The sliding seat 3 and the seat 2 can be locked quickly by simply pushing them together. To unlock, the locking piece 4 can be pulled down. It is convenient to use and can quickly lock the seat after closing or finishing the exercise, restricting its sliding and reducing the occurrence of misoperation and accidents.
