Advantageous effects

The invention provides a push-up exercise rack. The method has the following beneficial effects:

(1) when different resistances are needed, the magnetism of the electromagnetic block is controlled by the controller to disappear, at the moment, the electromagnetic block is separated from the magnetic part, the electromagnetic block returns to the resistance groove under the action of the elastic rotation rope, then the turntable is driven to rotate by the turntable driving mechanism, so that the resistance groove relative to the pull rod is changed into another one, the elastic rotation rope in the resistance groove is changed into another one, finally, the magnetism of the electromagnetic block is controlled by the controller to recover, under the action of the magnetic force, the electromagnetic block is adsorbed on the magnetic part, the actions of changing different elastic rotation ropes are completed, the whole process does not need manual operation, only the actions of changing are needed to be reached through the controller and the turntable driving mechanism, the operation is simple, a plurality of resistance groove forces are respectively provided with different elastic rotation ropes, and the requirements of various resistances are met.

(2) The exerciser pulls the handle, and then the drive initiative pull rod moves to the direction that is close to the exerciser along the mobile jib axle sleeve, then make the connecting rod take place corresponding rotation, drive the slider connecting rod at last and move along vertical, and the rotation of pulling elasticity gyration rope leaves the gyration pole, and release the exerciser and release the handle, under the effect of gyration pole, elasticity gyration rope twines in the gyration pole again, and the resistance of exerciser pulling handle is just provided by elasticity gyration rope, so change elasticity gyration rope just can reach the demand of changing different resistances, because the pull rod is generally in the tilt state, can make the carousel be in the state that corresponds the slope equally just can make magnetic part and electromagnetic block relative, but so easily lead to the electromagnetic block to drop from the resistance recess, influence normal resistance to change, so through the initiative pull rod, the articulated in proper order of connecting rod and slider pull rod, when the electromagnetic block loses magnetism, the pull rod unmanned pulling this moment, so under the effect of gyration pole the electromagnetism piece withdraws to resistance recess department, because the carousel is parallel with the horizontal plane, the resistance recess is vertical distribution, so under the effect of gravity, the electromagnetism piece falls into the resistance recess, resumes after the magnetic force when the electromagnetism piece again, is adsorbed by the magnetic part again, leaves resistance recess and moving direction along vertical, is in same straight line with gravity, the phenomenon that can not appear blocking.

(3) The person of exercising needs to temper left hand and right hand simultaneously generally speaking, so set up two resistance mechanism, satisfy the demand, and the setting up of stiffener makes the fuselage temperature more.

(4) When an exerciser needs to reduce weight, a large amount of time is continuously spent for exercising, and only one pull rod is pulled to be too boring, so that assemblies such as air bags are additionally arranged, after the exerciser pulls one of the handles, the handle drives the driving rod to move outwards of the main rod shaft sleeve, the volume of a sealed cavity formed by the piston, the sealing ring and the main rod shaft sleeve is increased, the air pressure in the sealed cavity is reduced, the sealed cavity is communicated with the air bags through air pipes, the air in the air bags moves into the sealed cavity under the action of the air pressure, one air bag in the air bag cavity and the air bag cavity is reduced, the acting force of the two air bags on the chassis is different, the chassis rotates towards the reduced air bag, the impact feeling similar to rowing is simulated, the other handle is rotated in the same way, the chassis rotates towards the other direction, and when the exerciser pulls the two handles respectively at different frequencies, the rotation with different frequencies can occur, thereby increasing the interest of the exerciser and effectively improving the exercise interest of the exerciser.

(5) Because the setting of gasbag for the person taking exercise has the slope of small angle, for guaranteeing person taking exercise's safety, is provided with the annular arch in the both sides of cushion for the person taking exercise is protected, prevents that it from falling from the cushion.

(6) The exerciser places the feet in the placing space during exercise, the arch-shaped pieces prevent the feet from being separated from the foot backing plates, and meanwhile, the friction plates are additionally arranged on the foot backing plates in direct contact with the feet, so that the feet can be prevented from sliding down from the placing space.

(7) Because the space variation degree in the airtight chamber is less for the degree that the gasbag reduces is less, and the power that division board both ends provided the chassis differs less, leads to the upset degree less easily, so set up in the both sides of keeping away from the pivot than the gasbag, can know through lever principle, and the farther away from as the fulcrum pivot, under the same effort, the degree of its upset is bigger, through being fixed in the gasbag and making its amplitude of change be the part in order to reach the effort to the chassis with the chassis contact on the base lateral wall.

(8) When the fuselage is installed, the limiting slide block on the fuselage is aligned with the limiting slide groove and slides in along the limiting slide groove, namely slides in along the dovetail groove, after the corresponding position is slid, the dovetail groove slides in through the two dovetail blocks, the dovetail groove abuts against the two sides of the fuselage along the dovetail groove, the dovetail groove is fixed through the fastening screws, under the action of the dovetail blocks and the limiting slide block, the fuselage is fixed, and the installation and the disassembly are convenient.

(9) When not needing the chassis to rotate, promote the carriage release lever to remove in the shifting chute for the adaptation inclined plane offsets with the shifting chute, then continues to promote the carriage release lever, under the effect of carriage release lever, tensile recovery spring makes the stopper tip stretch into the fixed slot, and the base can't rotate this moment, if needs the chassis to rotate, outwards pulls out the carriage release lever, under the effect of recovery spring, the stopper leaves in the fixed slot, whole income spacing inslot.
