DETAILED DESCRIPTION
[0022] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings.
[0023] Embodiment 1:
[0024] like Figure 1 , Figure 2As shown, the fitness equipment of the present invention comprises a slide rail 3 and a seat cushion 4 movable along the slide rail 3. The slide rail 3 is provided with a mounting groove, and a plurality of groups of pin holes are provided on both sides of the mounting groove. The seat cushion 4 can be fixed in the mounting groove of the slide rail 3 by plugging a conversion handle 3.1 into the pin holes so as to be immovable (i.e., immovable). A rear support seat 2 is provided at the bottom of the rear end of the slide rail 3, and a rear leg tube 2.1 is transversely provided at the bottom of the rear support seat 2. A front support seat 1 is provided at the bottom of the front end of the slide rail 3. A main frame 1.1 is provided forward at the bottom of the front support seat 1, and a front leg tube 1.2 is transversely provided at the front end of the main frame 1.1. A column 1.3 and a stand 1.4 are also vertically provided on the main frame 1.1. The column 1.3 is close to the front leg tube 1.2, and a display 13 is provided on the top. The upper end is inclined toward the slide rail 3, which is more convenient for human operation. The stand 1.4 is close to the slide rail 3 and is shorter than the column 1.3.
[0025] The fitness machine also includes a transmission mechanism, which mainly includes a spring box, a first one-way transmission mechanism, a secondary steering wheel 9 and a second one-way transmission mechanism. Figure 3 , Figure 4 As shown (where Figure 4 It mainly shows the cross-sectional structure of the power transmission part, and the display, pull rod and other components are not drawn on the top).
[0026] The column 1.3 is provided with a webbing pulley frame 6.1, a first spindle support frame 12.1 and a second spindle support frame 14.1 in sequence from top to bottom.
[0027] The webbing 6 passes over the pulley on the webbing pulley frame 6.1, and one end of the webbing 6 is connected to the pull rod 5. When the pull rod 5 is not in use, it is mounted on the pull rod bracket 5.1, and the pull rod bracket 5.1 is welded to the column 1.3 (see Figure 2 , Figure 3 ; Figure 1In order to clearly show the webbing 7, the pull rod bracket 5.1 is not completely drawn. The first core shaft 12 is fixedly arranged on the first core shaft support frame 12.1, and the spring box and the first one-way transmission mechanism are installed on the first core shaft 12. The spring box includes a hollow spring box body 7 in an I-shaped shape. The middle groove of the I-shaped spring box body 7 is a webbing winding groove 7.1. The other end of the webbing 6 is fixed on the webbing winding groove 7.1 and can be wound on the webbing winding groove 7.1. A volute spring 7.4 is arranged in the inner space of one bottom edge of the I-shaped spring box body 7. The inner end of the volute spring 7.4 is fixed on the first core shaft 12, and the outer end is fixed on the spring fixing rod 7.2.1 arranged at the corresponding position in the spring box body 7. The other bottom edge of the I-shaped spring box body 7 forms a webbing baffle for fixing the webbing 7 winding space. A first sleeve 7.5 is also fixed to the inner cavity of the spring box body 7. The first one-way ratchet 7.6 is fixed to the first sleeve 7.5 by riveting. When the first sleeve 7.5 rotates, the first one-way ratchet 7.6 rotates together. The first one-way ratchet 7.6 is unidirectionally clamped with the second sleeve 7.7, that is, when the webbing 6 is stretched under the drive of the pull rod 5, the rotation of the first one-way ratchet 7.6 will drive the rotation of the second sleeve 7.7. However, when the pull rod 5 is released, the spiral spring 7.4 rebounds. At this time, the spring box body 7, the first sleeve 7.5 and the first one-way ratchet 7.6 rotate in the opposite direction. The reverse rotation of the first one-way ratchet 7.6 will not drive the rotation of the second sleeve 7.7, and the rotation of the second sleeve 7.7 will not drive the rotation of the first one-way ratchet 7.6. The second sleeve 7.7 is clamped with the first belt pulley 8. In addition to being clamped with the first one-way ratchet 7.6, the first sleeve 7.5 is also supported by a bearing with the first spindle 12 and the second sleeve 7.7, and the first belt pulley 8 is also connected to the first spindle 12 through a bearing support. Figure 5 shown.
[0028] The second spindle support frame 14.1 is fixedly provided with the second spindle 14, and the second spindle 14 is supported and connected with the secondary steering wheel 9, the first small belt pulley 9.1 and the second small belt pulley 9.2 through the bearing support, and the first small belt pulley 9.1 and the second small belt pulley 9.2 are respectively located on both sides of the secondary steering wheel 9, such as Figure 7As shown, the first small pulley 9.1 and the secondary steering wheel 9 are integrally arranged, and there is no relative movement between them. The first small pulley 9.1 and the first belt disk 8 are connected by the first belt 8.1, and the secondary steering wheel 9 is unidirectionally clamped with the second one-way ratchet 9.3, that is, the rotation of the second one-way ratchet 9.3 can drive the rotation of the secondary steering wheel 9, but the rotation of the secondary steering wheel 9 cannot drive the rotation of the second one-way ratchet 9.3. A crank 11 is arranged on the vertical bracket 1.4, and a second belt disk 10 is fixed on the crank 11. The two ends of the crank 11 are respectively provided with a lazy car left pedal 11.1 and a lazy car right pedal 11.2, and the lazy car left pedal 11.1 and the lazy car right pedal 11.2 can rotate 360 degrees around the connecting end of the crank 11. The second belt disk 10 is connected to the second small pulley 9.2 by the second belt 10.1, and a tensioning belt pressing wheel 9.4 is also arranged between the two connecting ends of the second belt 10.1. An oblique rod 11.4 is connected between the top of the vertical support 1.4 and the second spindle support frame 14.1.
[0029] For ease of use, the back of the seat cushion 4 is provided with a backrest 4.1 and backrest armrests 4.2 extending from the back to both sides of the seat cushion 4.
[0030] When used as a rowing machine, the fixed pin of the conversion handle 3.1 is released, so that the seat 4 can move along the slide rail 3. At this time, the fitness person sits on the seat 4, with his feet placed on the left pedal 15.1 and the right pedal 15.2 of the rowing machine respectively, and pulls the pull rod 5 with both hands to stretch the webbing 6. During the stretching process, the webbing 6 drives the spring box body 7 to rotate. Since the first core shaft 12 is fixed, the spiral spring 7.4 is compressed as the spring box body 7 rotates. The first sleeve 7.5 also rotates as the spring box body 7 rotates. The first sleeve 7.5 drives the first one-way ratchet 7.6 to rotate, and further drives the second sleeve 7.7 and the first belt pulley 8 to rotate in turn. The first belt pulley 8 drives the first small pulley 9.1 and the secondary steering wheel 9 to rotate through the first belt 8.1. The rotation of the secondary steering wheel 9 provides sufficient resistance to the pulling rod 5 to meet the exercise requirements. At this time, the second one-way ratchet 9.3 will not rotate with the rotation of the secondary steering wheel 9, that is, the second belt pulley 9.2, the crank 11, the lazy car left pedal 11.1 and the lazy car right pedal 11.2 are all immobile. When the pull rod 5 is released, due to the rebound effect of the spiral spring 7.4, the spring box body 7 will be driven to rotate in the opposite direction, and the webbing 6 will be rewound onto the spring box body 7. At this time, the first sleeve 7.5 also rotates in the opposite direction, and drives the first one-way ratchet 7.6 to rotate in the opposite direction. However, due to the one-way clamping between the first sleeve 7.5 and the first one-way ratchet 7.6, the reverse rotation of the first one-way ratchet 7.6 does not drive the rotation of the second sleeve 7.7, that is, at this time, the secondary steering wheel 9 is immobile, and the spiral spring 7.4 has a small rebound resistance, and the webbing 6 can be quickly rewound onto the spring box body 7, which is convenient for the next stretching movement.
[0031] When used as a lazy bike, the position of the seat cushion 4 is adjusted, and the fixing pin of the conversion handle 3.1 is fixed in the pin hole of the slide rail 3. After the fitness person sits on the seat cushion 4, the back is leaned against the backrest 4.1, the backrest armrests 4.2 are held with both hands, and the feet are placed on the left pedal 11.1 and the right pedal 11.2 of the lazy bike respectively to step on them. As the feet step on them, the crank 11 is driven to rotate, and the rotation of the crank 11 drives the second belt pulley 10 to rotate. The second belt pulley 10 drives the second small belt pulley 9.2 to rotate through the second belt 10.1, and the second small belt pulley 9.2 further drives the second one-way ratchet 9.3 to rotate, and the second one-way ratchet 9.3 drives the secondary steering wheel 9 to rotate, providing sufficient resistance to the lazy bike function and achieving the purpose of exercise.
[0032] The secondary steering wheel 9 rotates in opposite directions when used as a rowing machine and a lazy bike. The display 13 is used to display some parameters of exercise, such as the number of times the pull rod 5 is stretched and the strength when used as a rowing machine, and the number of times the pedal is stepped on and the speed when used as a lazy bike.
