The purpose of the utility model realizes through following technical scheme: a kind of device balance weight mechanism, comprise underframe, and chassis top surface is connected with the adjusting column through bolt; Regulating column is bending shape, comprises rake and bending part, and the rake of regulating column is provided with a plurality of through holes of arranging up and down; One of them through hole draws pin to be connected with stretch cord through adjusting and regulates seat, and stretch cord is regulated seat and is provided with handle, is connected with first pulley and stretch cord pulley base on the bending part of adjusting column; Place about first pulley and stretch cord pulley base; Also be connected with second pulley on the underframe, second pulley is positioned at the below of regulating the column bending part, and stretch cord is regulated the end that seat is connected with the stretch cord group; The slide-bar that the other end of stretch cord group passes said stretch cord pulley base is connected with an end of first steel wire rope; The other end of first steel wire rope passes second pulley and is connected with support, and support is connected with the 3rd pulley, regulates to run through in the position of column bending part between said first pulley and stretch cord pulley base to be connected with second steel wire rope; One end of second steel wire rope is connected with first wire line hitch; First wire line hitch places the upper surface of regulating the column bending part, and the other end of second steel wire rope passes the 3rd pulley and first pulley is connected with second wire line hitch, and second steel wire buckle is near first pulley.

The further improvement of the utility model is: said stretch cord group comprises two Connection Blocks; Be connected through the multiply stretch cord between two Connection Blocks; One of them Connection Block is regulated seat with stretch cord and is connected; Another Connection Block is connected with first steel wire rope, and the multiply stretch cord passes the slide-bar of stretch cord pulley base.

The utility model compared with prior art has the following advantages: size that can resistance, and it is comparatively convenient to use, and because stretch cord has good buffer capacity; Use safer; Dragulator can be engaged in the combined trainer as on draw, drop-down, row the boat, chest expanding, function such as box use, and can also cooperate other gadget parts as other function of tempering shank, compare with the adjuster that contains balancing weight; Low price, it is comparatively convenient to install.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Label among the figure: 1-underframe, 2-bolt, 3-adjusting column, 4-through hole, 5-regulate and draw pin, 6-stretch cord to regulate seat, 7-handle, 8-first pulley, 9-stretch cord pulley base, 10-second pulley, 11-slide-bar, 12-first steel wire rope, 13-the 3rd pulley, 14-support, 15-second steel wire rope, 16-first wire line hitch, 17-second wire line hitch, 18-Connection Block, 19-stretch cord.

The specific embodiment:

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show the specific embodiment of a kind of device balance weight mechanism of the utility model like Fig. 1, comprise underframe 1, underframe 1 upper surface is connected with through bolt 2 and regulates column 3; Regulate column 3 and be bending shape; Comprise rake and bending part, the rake of regulating column 3 is provided with a plurality of through holes of arranging up and down 4, and one of them through hole 4 draws pin 5 to be connected with stretch cord through adjusting and regulates seat 6; Stretch cord is regulated seat 6 and is provided with handle 7; Be connected with first pulley 8 on the bending part of adjusting column 3 and place, be connected with second pulley 10 on the underframe 1 with stretch cord pulley base 9, the first pulleys 8 and stretch cord pulley base about 9; Second pulley 10 is positioned at the below of regulating column 3 bending parts; Stretch cord is regulated the end that seat 6 is connected with the stretch cord group, and the slide-bar 11 that the other end of stretch cord group passes stretch cord pulley base 9 is connected with an end of first steel wire rope 12, and the preferred stretch cord group of the utility model comprises two Connection Blocks 18; Be connected through multiply stretch cord 19 between two Connection Blocks 18; One of them Connection Block 18 is regulated seat 6 with stretch cord and is connected, and another Connection Block 18 is connected with first steel wire rope 12, and multiply stretch cord 19 passes the slide-bar 11 of said stretch cord pulley base 9; The other end of first steel wire rope 12 passes second pulley 10 and is connected with the support 14 of the 3rd pulley 13; Run through an end that is connected with second steel wire rope, 15, the second steel wire ropes 15 in the adjusting position of column 3 bending parts between first pulley 8 and stretch cord pulley base 9 and be connected with the upper surface that first wire line hitch, 16, the first wire line hitch 16 place adjusting column 3 bending parts; The other end of second steel wire rope 15 passes the 3rd pulley 13 and first pulley 8 is connected with second wire line hitch, 17, the second steel wire buckles 17 near said first pulley 8.
