Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 7, an embodiment of the present invention provides a training bicycle, including a frame 1, the frame 1 is provided with a front wheel and a rear wheel 2, a pedal 3 is rotatably provided in the middle of the frame 1, the pedal 3 is connected to a first chain wheel 4, the rear wheel 2 is connected to a second chain wheel 5, a chain 6 is provided between the first chain wheel 4 and the second chain wheel 5, and a person steps on the pedal 3 to drive the rear wheel 2, the present invention is an improvement of the existing bicycle structure, and is characterized in that the invention is on the front wheel, the front wheel includes an axle 7 fixed on the frame 1, a worm rod part 8 is fixed on the axle 7, a disc 9 is also fixed on the axle 7, a round rod 10 is vertically provided on the disc 9, the disc 9 is perpendicular to the axle 7, the round rod 10 is parallel to the axle 7, a baffle 11 is provided at the outer end of the round rod 10, a first axle seat 12 is also fixed on the disc 9, the first rotating shaft seat 12 is rotatably provided with a first rotating shaft 13, the first rotating shaft 13 is fixedly connected with a worm wheel 14, the axis of the worm wheel 14 is perpendicular to the axis of the axle 7, the worm wheel 14 is vertically meshed with the worm rod part 8 for transmission, the first rotating shaft 13 is also fixedly connected with a cam 15, the outer edge of the disc 9 is slidably sleeved with a wheel rim 16, a first connecting rod 17 is radially arranged in the wheel rim 16, the end part of the first connecting rod 17 is slidably sleeved on the axle 7 through a shaft sleeve 18, the first connecting rod 17 is provided with a second rotating shaft seat 19, the second rotating shaft seat 19 is rotatably provided with a second rotating shaft 20, the second rotating shaft 20 is fixedly provided with a round wheel 21, the wheel rim 16 is further provided with a baffle plate 22 along the radial direction, the baffle plate 22 and the first connecting rod 17 are arranged at intervals and are not in the same plane any more, one end of the baffle plate 22 is provided with a round hole 23, the round rod 10, the round rod 23 is sleeved with a pressure spring 24, and two end faces of the pressure spring 24 respectively abut against the space between the baffle 22 and the baffle 11.
The round rods 23 are 3, and 3 round rods 23 are uniformly distributed along the circumferential direction of the disc 9.
The outer side of the baffle plate 11 is provided with a screw cap 25, and the screw cap 25 is rotated to adjust the distance between the baffle plate 11 and the baffle plate 22.
A tire (not shown) is mounted on the rim 16.
When the rear wheel is driven by manpower to drive the frame to move forwards, the rim rotates around the axle, the rim drives the disc to rotate, the worm part is fixed on the axle due to the meshing transmission of the worm wheel and the worm part, the worm wheel is connected with the first rotating shaft seat on the disc in a rotating way, so that the worm wheel can rotate around the axle along with the disc, the worm wheel can also rotate (namely the worm wheel can rotate around the first rotating shaft), a cam rotating synchronously with the worm wheel can periodically apply force on the circular wheel, due to the existence of a pressure spring on the circular rod, the rim can perform reciprocating translational motion (namely the rim slides relative to the disc and the axle, the sliding direction is the axial direction of the axle), therefore, when a person rides, the gravity center position of the frame is changed, the front wheel is difficult to keep linear motion, the person needing to ride can balance through core force and adjustment of the gravity center position to avoid falling down, the difficulty, therefore, the training of the overall balance force and coordination ability, the training of the core strength and the interest are achieved.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
