Description

Technical Field

[0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a multifunctional training device. Background Art

[0002] As we all know, in the field of fitness equipment, all current fitness equipment has limitations for muscle group training. For example, the equipment for upper limb and lower limb training is not universal, and users need to set up training equipment separately to complete the training of muscle groups in various parts. Even the upper limb training is divided more finely, and the equipment for biceps, triceps, shoulders, back and chest is also different.

[0003] Furthermore, the driving parts of the training equipment currently on the market cannot be adjusted, that is, the supporting parts are fixed when they are subjected to force, and the upper and lower positions cannot be moved or converted, so the conversion of the training parts cannot be completed. Summary of the invention

[0006] The sliding device includes a positioning plate and a drag plate, the fixing pin is fixed on the positioning plate and passes through the positioning plate; the drag plate is provided with a handle and a limit screw, the limit screw passes through the drag plate and is inserted into the guide limit groove; on the inner side of the column, the positioning plate and the drag plate are fixed together by a drag positioning block, and on the outer side of the column, the positioning plate and the drag plate are fixed together by an outer fixing plate.

[0007] On the swing rod, a limit lever is fixed on the left and right sides of the hinge shaft respectively, and the limit lever is used to block and limit the sliding device when one end of the force application rod swings to the highest point or the lowest point.

[0008] On the sliding device, a pulling steel cable is fixed on the top, and two guide wheels are fixed on the top of the column or the crossbeam corresponding to the pulling steel cable. The pulling steel cable and the counterweight block inside the column are connected together through the guidance of the guide wheels.

DETAILED DESCRIPTION

[0018] Referring to the attached drawings,

[0019] A multifunctional training device comprises a base frame 1, on the top of which upright posts 2 are vertically arranged, and a gantry is formed by connecting the upright posts 2 with cross beams 4 on the tops of the upright posts 2. The above gantry structure constitutes the overall structure of the multifunctional training device.

[0020] There are two columns 2 and they are symmetrically arranged on the left and right. The various parts on the two columns 2 are symmetrically installed and fixed. A cavity is arranged inside the column 2. A first sealing plate 24 is arranged on the front side of the column 2. The first sealing plate 24 is provided with a height scale and a plurality of positioning holes are arranged at corresponding height positions; a second sealing plate 28 is arranged on the rear side of the column, and a guide limit groove 20 is vertically arranged on the second sealing plate 28; a sliding device is arranged on each column 2, and the specific structure of the sliding device is as follows: the sliding device includes a positioning plate 21 and a drag plate 22, the fixing pin 26 is fixed on the positioning plate and penetrates the positioning plate, and the fixing pin 26 is arranged with The corresponding positioning holes are fixed to realize the vertical positioning of the entire sliding device on the column; a handle is provided on the drag plate 22 and a limit screw 35 is provided, and the limit screw 35 passes through the drag plate and is inserted into the guide limit groove 20, and its function is to limit the fixed position of the sliding device on the column to prevent it from being set too high or too low; on the inner side surface of the column 2, the positioning plate 21 and a drag plate 22 are fixed to one body through a drag positioning block 27, and on the outer side surface of the column, the positioning plate 21 and a drag plate 22 are fixed to one body through an outer fixing plate 23. Through this structural setting, the sliding device is designed into a square groove, so as to fix it on the column and realize precise positioning. The inner side surface of the sliding device is a drag positioning block 27, and a swing rod 3 is fixed on the drag positioning block 27 through a hinge shaft 33. It should be noted that when the swing rod is fixed, the middle part is hinged and fixed to the drag positioning block 27 through the hinge shaft 33, and a counterweight rod 31 is provided at both the front and rear ends of the swing rod. In actual use, a counterweight device is fixed on one of the two counterweight rods 31; corresponding to one of the swing rods 31, at least one force rod 32 is provided on its inner side surface, and the training personnel apply force to the force rod 32, so as to realize the lifting and falling of the entire swing rod 3 in the counterweight state.

[0021] Furthermore, when the present multifunctional training device is actually used, its driving principle is to drive the force rod 32 through the legs or upper limbs, and the force rod 32 overcomes the counterweight on the counterweight rod 31 to realize the in-situ hinged swing of the swing rod. In this process, in order to prevent the swing rod from swinging too much or flipping on the hinge axis, a limit lever 34 is fixed on the left and right sides of the hinge axis 33 on the swing rod 3, respectively. When one end of the force rod 32 swings to the highest point or the lowest point, the limit lever 34 realizes the blocking and limiting of the dragging positioning block 27.

[0022] Furthermore, when the device is adjusting the sliding device up and down, a pulling steel cable 44 is fixed to the top of the dragging positioning block 27 of the sliding device, and two guide wheels are fixed to the top of the column 2 or the crossbeam 4 corresponding to the pulling steel cable 44. The two guide wheels are respectively the first guide wheel 41 and the second guide wheel 42. The pulling steel cable 44 and the counterweight block 43 inside the column 2 are connected together through the coordinated guidance of the two guide wheels. When the counterweight block 43 described here is set, the weight of the counterweight block is ≦the weight of the sliding device. When setting in this way, it can be more labor-saving when dragging the sliding device up and down.

[0023] In order to further improve the vertical guiding stability of the device, a guide track 5 is vertically arranged on the column 2. The sliding device realizes the guided movement in the vertical direction through the guide track 5, which can prevent the entire sliding device from tilting during the vertical movement.

[0024] In summary, when using this device, the counterweight devices can be fixed on the counterweight rods at both ends, and the force rods can be lifted in situ by the legs or upper limbs. In summary, the structural design of the present invention is novel and simple, easy to manufacture and implement, and has a low cost, which is beneficial to large-scale promotion in the fitness field. It is an ideal multi-functional trainer.
