[0022] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0023] refer to Figure 1-4 As shown, the utility model discloses a seat sliding adjustment mechanism for a fitness bike, comprising a guide rail 1, a sliding bracket 2, a roller 3, a stopper 4, a handle 5 and a seat 6;
[0024] A slide groove 11 is provided on the side of the guide rail 1;
[0025] At least two rollers 3 are installed on the inner wall of the sliding bracket 2 at intervals in front and back, and are rotatably matched with the limiting member 4;
[0026] The circumferential surface of the limiting member 4 is provided with an elastic arm 41 that abuts against the upper wall or the lower wall of the sliding groove 11 as the limiting member 4 rotates;
[0027] The handle 5 is arranged on the outside of the sliding bracket 2 for easy operation, and the handle 5 is coaxially connected with the rotating shaft 42 of the limiting member 4;
[0028] The seat 6 is mounted on the upper surface of the sliding bracket 2 .
[0029] Through the above scheme, the sliding bracket 2 of the utility model can achieve smooth movement through the rolling cooperation between the roller 3 and the slide groove 11 of the guide rail 1, so as to facilitate stepless adjustment; the locking between the sliding bracket 2 and the guide rail 1 is achieved by relying on the limit member 4 linked with the handle 5. When the limit member 4 is rotated to the point where the elastic arm 41 is against the upper wall or lower wall of the slide groove 11, the purpose of braking and locking is achieved, and the sliding bracket 2 cannot be moved, that is, the seat 6 is relatively fixed at a specific position on the guide rail 1. When the limit member 4 is rotated to the point where the elastic arm 41 is separated from the upper wall or lower wall of the slide groove 11, the sliding bracket 2 can move smoothly and perform position adjustment.
[0030] See also Figure 1-4 , showing the first embodiment of the utility model.
[0031] The upper and lower walls of the above-mentioned slide groove 11 are both provided with a roller groove 111 and a locking step 112 in parallel on the left and right; the roller groove 111 is an arc-shaped groove, which is adapted to the circumferential shape of the roller 3; the elastic arm 41 of the limit member 4 movably abuts against the locking step 112 to realize the braking function.
[0032] The guide rail 1 is provided with a slide groove 11 on both sides; the sliding bracket 2 is a U-shaped structure with an opening facing downward, and two rollers 3 are installed on the inner walls of both sides. The two groups of rollers 3 on the left and right make the sliding cooperation between the guide rail 1 and the sliding bracket 2 more stable.
[0033] Furthermore, the inner walls of both sides of the sliding bracket 2 are both installed with limit members 4, and the limit members 4 on both sides are arranged at the same height; the handle 5 is a U-shaped member, and its two ends are coaxially connected to the rotating shafts 42 of the two limit members 4. The left and right limit members 4 are installed at the same height, which can make the locking of the sliding bracket 2 more secure, and only one handle 5 can control the two limit members 4 synchronously.
[0034] Secondly, the rotating axes of the above-mentioned roller 3 and the limit member 4 are located on the same plane to achieve coplanarity, and the circumference of the limit member 4 is symmetrically provided with two elastic arms 41 180° around its own midpoint. The two elastic arms 41 are movable to abut the upper wall and the lower wall of the slide groove 11 respectively as the limit member 4 rotates.
[0035] A plane 43 is provided on the circumference of the stopper 4 at a position spaced apart from the elastic arm 41 . When the stopper 4 rotates until the plane 43 is parallel to the slide slot 11 , the elastic arm 41 completely separates from the upper wall or the lower wall of the slide slot 11 to avoid interfering with the sliding of the sliding bracket 2 .
[0036] In the first embodiment, the elastic arm 41 is a curved arm.
[0037] See also Figure 5 , shows a second embodiment of the utility model, mainly the limiting member 4 of the second embodiment.
[0038] In the second embodiment, the elastic arm 41 is a straight arm. Since the elastic arm 41 is a straight arm, when the stopper 4 is rotated to the point where the elastic arm 41 contacts the upper wall / lower wall of the slide slot 11, the elastic arm 41 is actually in surface contact with the upper wall / lower wall of the slide slot 11, and the pressure to be overcome when the stopper 4 rotates to disengage from the upper wall / lower wall of the slide slot 11 is greater than the force at the locking position, so the stopper 4 can be effectively prevented from automatically rotating, and the handle 5 must be manually rotated to pass this dead point.
[0039] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
