DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figures 1 to 5 The present invention provides a technical solution: a pedal exercise bike with an adjustable seat, comprising a chassis 1, and two pipe frames 2 fixedly connected thereto, the two pipe frames 2 are arranged in parallel, and a seat 3 is provided on the pipe frames 2, a threaded base 4 is fixedly connected to the bottom of the seat 3, the threaded base 4 is threadedly connected to a locking screw 5, the locking screw 5 is sleeved with two clips 6, the two clips 6 are distributed in upper and lower mirror symmetry, and arc pieces 601 integrally formed therewith are provided on both sides of the clips 6, and the pipe frame 2 is inserted between the two arc pieces 601, and the locking screw 5 is threadedly connected to a locking knob 7.

[0025] In this embodiment, the chassis 1 and the pipe rack 2 are fixedly welded with anti-collision insurance 15 at the front and rear ends. The front end of the anti-collision insurance 15 is fixedly connected to the rubber airbag block 16. The rubber airbag block 16 is a hollow elliptical gas filled with nitrogen and has good impact resistance.

[0026] In this embodiment, the seat 3 adopts an ergonomic design, and a cushion 14 is arranged on the top thereof. The cushion 14 is woven into a double-sided mesh shape with polyester fiber. The mesh is a six-sided breathable hollow three-dimensional structure, and air and water can flow freely, and can form a moist and hot microcirculation air layer. It is moderately soft and hard, can be rolled, and is convenient to carry and store. It is not easy to deform, and does not have any fillers such as sponges, so it has the advantages of being washable, quick-drying, anti-mite, and anti-bacteria, and is suitable for adults, especially children. The bottom of the cushion 14 is fixedly connected to a rubber suction cup, and the rubber suction cup adsorbs the upper surface of the seat 3. The adsorption force provided by the rubber suction cup prevents the relative displacement of the cushion 14 and the seat 3, thereby improving stability. The two sides of the seat 3 are fixedly connected to the support 12, and the support 12 is hinged to the armrest 13 through a 90-degree damping hinge, and can be stored vertically at 90 degrees. On the one hand, the armrest 13 can realize the function of a common armrest; on the other hand, it can protect the user and prevent the user from falling from the seat 3. The surface of the armrest 13 is wrapped with a layer of wear-resistant leather, which feels comfortable. The seat 3 is also provided with a separate movable lumbar support, and the rebound force is concentrated on the movable lumbar support, which provides the user with the closest support. The movable lumbar support can adjust the curvature to relax the entire lower back and fit comfortably to the waist and back, so that the spine can be relaxed, thereby relieving the fatigue of the spine.

[0027] In this embodiment, if Figures 3 to 5 As shown, the threaded base 4 is an inverted frustum structure with a larger upper portion and a smaller lower portion, and an internal threaded hole is provided at its center. The surface of the internal threaded hole is coated with nut anti-loosening liquid. When in use, the nut anti-loosening liquid is first applied to the internal threaded hole, and then the locking screw 5 is screwed on to achieve the anti-loosening effect.

[0028] A groove 602 is provided on one side of the clip 6 close to the pipe rack 2, and limiting grooves 603 formed integrally with the clip 6 are provided on both sides of the groove 602, and the groove 602 is fixedly connected to one end of the elastic element 8, the elastic element 8 is a cylindrical helical compression spring, and the other end of the elastic element 8 is fixedly connected to the roller bracket 9, the length of the roller bracket 9 is less than the depth of the groove 602, and the width of the roller bracket 9 is equal to the width of the groove 602, the roller bracket 9 is connected to the roller 10 by a bearing, and the two outer side walls of the roller bracket 9 are fixedly connected to the limiting blocks 11, and the limiting blocks 11 slide to fit the limiting grooves 603. The top and bottom outer side walls of the pipe rack 2 are both provided with slide rails 201, and the vertical section of the slide rails 201 is in the shape of an arc. When the elastic element 8 reaches the minimum telescopic length, the slide rails 201 roll to fit the roller 10, and the clip 6 abuts against the pipe rack 2.

[0029] In order to increase the stability of the clip 6 on the pipe frame 2, the contact surface between the clip 6 and the pipe frame 2 is set to a rough surface. At the same time, in order to reduce the friction resistance between the clip 6 and the pipe frame 2 during the adjustment of the seat 3, a roller 10 is set on the clip 6. By utilizing the telescopic function of the elastic element 8, the roller 10 can be close to the slide rail 201 on the pipe frame 2, and the original sliding friction is changed into rolling friction, which greatly reduces the resistance encountered when moving the clip 6.

[0030] The process of adjusting the position of the seat 3 is as follows: first, unscrew the locking knob 7, the clip 6 loses the restraint of the locking knob 7, the distance between the two clips 6 becomes larger, and the locking screw 5 can move freely on the pipe frame 2, and the position of the seat 3 can be quickly adjusted by pushing the seat 3. After the adjustment is completed, tighten the locking knob 7, the upper and lower clips 6 are pressed against the pipe frame 2, and finally the elastic element 8 reaches the minimum telescopic length, the roller 10 squeezes the slide rail 201, and the clip 6 abuts against the pipe frame 2. By setting the contact surface between the clip 6 and the pipe frame 2 to a rough surface, the friction between the clip 6 and the pipe frame 2 can be increased, so that the clip 6 is fixed on the pipe frame 2, so that the position of the locking screw 5 and the seat 3 remains unchanged.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
