Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.

As shown in fig. 1 and 2:

The structure of the invention is composed of a frame group 1, a sliding seat group 2, a seat cushion group 3, a pull rope group 4 and the like.

The frame set 1 is attached to the ground by a base 101 with an I-shaped structure, so that the self-weight rowing machine can move more stably and firmly, a left guide rail 102 and a right guide rail 103 are obliquely and symmetrically arranged on two sides of the base 101 with the I-shaped structure, and the tail ends of the left guide rail 102 and the right guide rail are connected with the base 101 through a connecting rod set 105.

one end of a pull rope 401 in the pull rope group 4 is fixed at the rear end of the right guide rail 103, and a pulley 406 is arranged at the rear end of the left guide rail 102. A connecting rod group 104 is fixed at the middle position of the front end of the frame group 1, a pull handle 411 connected with a pull rope 401 on the pull rope group 4 is arranged at the position of the connecting rod group 104, a pulley 402 is arranged on the connecting rod group 104, and the pull handle 411 is connected with the end part of the pull rope 401 passing through the pulley 402.

Two moving wheels 106 are symmetrically arranged at the bottom of the front end of the frame group 1, so that the position of the rowing machine can be moved conveniently.

The slide seat group 2 consists of a slide rail group 20 and a pedal group 21. The slide rail set 20 has a slide rail 201 and a support rod 202, and the slide rail 201 is fixed on the support rod 202. Two cross bars 205 are fixed at the front end of the support bar 202, and two rollers 203 are respectively arranged at two sides of each cross bar 205. The two rollers 203 on one side are placed in the left guide rail 102, and the two rollers 203 on the other side are placed in the right guide rail 103 and reciprocate in the guide rail direction. The upper side of the front end of the support rod 202 is provided with a pedal group 21, and feet are placed during movement and slide up and down along the guide rail along with the whole sliding seat group 2. The pulley 407 and the pulley 410 are symmetrically arranged on both sides of the front end of the slide rail set 20.

the seat cushion group 3 shown in fig. 3 is composed of a seat cushion 301, two sets of rollers 302, two sets of stopper rollers 303, and the like. The seat cushion group 3 moves on the slide rail 201 through the roller 302 and along the direction of the slide rail 201 to realize the forward and backward movement of the rowing machine seat cushion 301, and the stop roller 303 cooperates with the slide rail 201 to locate the moving range of the seat cushion 301 by the front and back two stop rods 206 arranged on the same side of the slide rail.

The included angle between the slide rail 201 and the base 101 is smaller than the included angle between the guide rail (the left guide rail 102 or the right guide rail 103) and the base 101, that is, the slide seat set 2 can move up and down along the direction of the guide rail, and the moving direction of the slide seat set 2 and the moving direction of the seat cushion 301 form an included angle, the moving direction of the seat cushion 301 is closer to the horizontal, and the moving direction of the whole body formed by the slide seat set 2 and the seat cushion set 3 is more inclined.

The pull rope group 4 is composed of a pull rope 401, a pull handle 411 and a plurality of pulleys, after the pull rope 401 is led out from the pull handle 411, the pull rope sequentially passes through a pulley 402, a pulley 403, a pulley 404, a pulley 405 and a pulley 406 on the frame group 1, a pulley 407 on the slide seat group 2, pulleys 408 and 409 on the frame group 1, a pulley 410 on the slide seat group 2, and finally the tail end of the pull rope is fixed at the position A at the rear end of the right guide rail 103. The pulley 407 and the pulley 410 on the pulley group 2 are left-right symmetrical to balance the forces. When the pull handle 411 is pulled, the pull rope 401 drives the pulleys to rotate or move, and the sliding seat group 2 and the seat cushion group 3 do synchronous motion through the length change of the pull rope 401, so that the motion function of the rowing machine is realized.

The invention is composed of a frame group 1, a sliding seat group 2, a seat cushion group 3 and a pull rope group 4. The frame set 1 is provided with an inclined guide rail, and the sliding seat set 2 is provided with a sliding rail set 20, a pedal set 21 and the like. The trainer can move back and forth along the sliding rails 201 while sitting on the seat cushion 301, and the sliding seat group 2 can move up and down along the inclined rails on the frame group 1. One end of the pull rope 401 is arranged at the front end of the frame set 1, the pull handle 411 is connected with the end, the pull rope 401 bypasses all pulley blocks on the frame set 1 and the pulley block set 2, and finally the tail end of the pull rope 401 is fixed at the rear end of the frame set 1. When a trainer sits on the seat cushion 301 to apply force to pull the pull handle, the trainer performs ascending motion along the inclined guide rail along the sliding seat group 2 as a load, when the trainer does not apply force to the pull handle any more after the pull handle is pulled out, the trainer performs descending motion along the inclined guide rail along the sliding seat group 2 under the action of gravity to recover to an initial point, and meanwhile, the trainer performs front-and-back motion close to the horizontal motion along the sliding rail 201 of the sliding seat group 2 on the seat cushion 301, so that the complete motion of the rowing machine body building is realized.

the invention relates to a fitness equipment with a rowing function, which can fully utilize the self weight condition of a trainer to achieve an ideal training effect.

in addition, a resistance adjusting structure may be added to the foregoing example.

This example uses a latex tube to provide resistance as shown in fig. 4:

Latex tube 501 is mounted on slide assembly 2. The upper end of the latex tube 501 is fixed with the support bar 202 through a fixing piece 507, and the lower end of the latex tube 501 is hung at the lower end of the sliding seat group 2 through a selection piece 502. The adjusting knob 505 is fixed on the frame assembly 1 through a bracket 506. The latch 503 is mounted to the frame set 1. The adjusting knob 505 is rotated to drive the latch 503 to move up and down by adjusting the cable 504, so as to connect or disconnect the selecting piece 502 to achieve the function of adjusting the resistance. In the connected state, the lower end of latex tube 501 is fixed with frame set 1 and the upper end is fixed with slide set 2, and when slide set 2 moves, latex tube 501 is stretched, thereby generating resistance. In this case, the latex tube 501 may be replaced by other elastic parts such as a spring, a stretch cord, etc., or even by an electromagnetic control system.
