The utility model relates to fitness equipment, in particular to a counterweight mechanism of a comprehensive training device for fitness.

Background technique

With the improvement of living standards, people pay more and more attention to their body and health. As a result, more and more fitness equipment has entered people's lives.

The popular strength fitness equipment on the market now includes a rack. The rack is connected with two vertical guide bars. The rack is also connected with a plurality of first pulleys and a plurality of second pulleys. The weight piece is arranged on the two guide rods. On the rod, the weight piece is connected to the moving pulley frame, the moving pulley frame is connected to the moving pulley, the middle part of the wire rope is set on the moving pulley, one end of the wire rope is fixed with the frame after passing through a plurality of first pulleys, and the other end of the wire rope passes through the frame. A pull handle is connected behind a plurality of second pulleys.

When exercising, pull the handle, the wire rope drives the moving pulley to move up and down, and the weight-bearing training effect is achieved through the weight plate. The weight piece of this structure has high cost and high noise, and after the weight piece is pulled up and raised, when the pulling force disappears, it cannot fall back to its original position instantly. At this time, the movement is very unsmooth, the synchronization is slow, the recovery is slow, and the training cannot be achieved. Effect.

SUMMARY OF THE INVENTION

The purpose of the utility model is to overcome the deficiencies of the prior art, and to provide a counterweight system for a comprehensive training device that is low in cost, low in noise, smooth in movement, fast in synchronization, and fast in recovery, and conforms to the mechanics of human muscle movement.

The purpose of the present utility model is achieved as follows: the counterweight system of the comprehensive training device includes a frame, on which two vertical guide rods are connected, and each guide rod is respectively connected with a buffer pad, and the two buffer pads are in the same on the horizontal plane; the counterweight system also includes two to six tension bar selection frames, a vertical selection rod and a latch, and the two to six tension bar selection frames are sequentially sleeved on the two guide bars from bottom to top. On the rod, the lowermost tension bar selection frame is arranged above the buffer pad; the middle of each tension bar selection frame is provided with a vertical selection rod socket and a longitudinal outer pin hole, and the selection rod is inserted into each tension rod. In the selection rod jack of the tension bar selection frame, an inner pin hole is arranged on the selection rod, the number of the inner pin hole is equal to the number of the outer pin hole, and each inner pin hole and the corresponding outer pin hole are arranged coaxially, so The bolts are inserted into one group of the outer bolt holes and the inner bolt holes, and the bolts connect the tension bar selection frame with the selection rod; the tension bars are respectively connected at both ends of each tension bar selection frame, and are fixed at the bottom of the rack. Two lower fixing pieces are connected, the lower end of the tension bar at one end of each tension bar selection frame is connected with one of the lower fixing pieces, and the lower end of the tension bar at the other end of each tension bar selection frame is connected with the other lower fixing piece.

Through the above design of the utility model, the counterweight can be quickly selected. When choosing, the weight is gradually increased from small to large. Insert the pin into the top outer pin hole and inner pin hole, and the pin will connect the first tension bar selection frame from top to bottom with the selection rod. At this time, pull the handle, the steel cable drives the moving pulley to move up, the first tension bar selection frame moves up on the guide rod, and the tension bars at both ends of the first tension bar selection frame generate resistance, so as to achieve the effect of exercise.

When the counterweight needs to be increased gradually, retract the pull handle, reset the moving pulley and the first pull bar selection frame, pull out the latch, and then move the latch down and insert it into the second outer latch hole, so that the second A tension bar selection frame is connected with the selection rod. At this time, pull the handle, the steel cable drives the moving pulley to move upward, the first tension bar selection frame and the second tension bar selection frame move up on the guide rod together, the first tension bar selection frame and the second tension bar Choose the tension bars at both ends of the rack to create more resistance, thus achieving the effect of the exercise. If you need to continue to increase the counterweight, move the latch down and insert it into the required outer latch hole.

The utility model selects according to its own needs, is fast and convenient, the tension bar selection frame and the tension bar combined counterweight system have low cost, fast force recovery and fast synchronization.

In order to make the range of the counterweight more reasonable, there are five tension bar selection frames and five inner pin holes.

The tension bar selection frame of the utility model comprises a selection block and two connecting pieces, the two connecting pieces are symmetrically and fixedly connected at both ends of the selection block, the weights of the five selection blocks are equal, and the length of the connecting pieces gradually shortens from top to bottom , easy to connect the tension bar.
