Abstract
The utility model provides a simple exerciser for dorsal muscle extension, and belongs to the technical field of sports equipment. The problems that a conventional dorsal muscle extension exerciser is large in size and not suitable for families are solved. The simple exerciser for the dorsal muscle extension comprises a stool, a rear support, two front driving frames and a series of strong springs, wherein the rear support is connected to the stool in an insertion manner, external connection edge wings are arranged on two sides of the rear support and hinged with the two front driving frames respectively; and one end of each strong spring is connected with the rear support in an insertion manner, and the other ends the strong springs are connected with the front driving frames. The simple exerciser for the dorsal muscle extension is small in size and simple in structure; the stretching strength can be adjusted; deltoid muscles and latissimus dorsi muscles can be exercised at the same time; and the simple exerciser for the dorsal muscle extension is very suitable for exercises of common families.
Description
Technical field
The utility model belongs to the sports apparatus technical field, particularly a kind of simple and easy extension of back muscles exercising machine.
Background technology
Existing extension of back muscles hits training aids, the dorsal muscles training device that comprises sliding dorsal muscles training device and upper and lower Straight pull, described sliding dorsal muscles training device is as chest expanding exercise, the variable weights that drives rear portion to stretch reaches the purpose of exercise dorsal muscles, this device is mainly that volume is larger, carrying is inconvenient, has limited using area.
The dorsal muscles training device volume of upper and lower Straight pull is little, features simple structure, but the position of this device training is mainly deltoid muscle, and the training effect of latissimus dorsi is far from the effective of sliding dorsal muscles training device, therefore the sliding dorsal muscles training device of easy, applicable family is only that market lacks.
Summary of the invention
The purpose of this utility model is for existing the problems referred to above, and has proposed a kind of features simple structure, the obvious simple and easy extension of back muscles exercising machine of stretching result of use.
The purpose of this utility model can realize by following technical proposal: a kind of simple and easy extension of back muscles exercising machine, it is characterized in that, it comprises bench, after-poppet, two forerunner's framves and a series of brute spring, described after-poppet is plugged on bench, all there is the outer limit wing that connects in the both sides of after-poppet, and it is hinged with two forerunner's framves respectively to connect the limit wing outward, above-mentioned brute spring one end and after-poppet are pegged graft, and the other end and forerunner's frame are pegged graft.
Described outer to connect the limit wing hinged with forerunner's frame horizontal direction, and forerunner's frame rotates along horizontal plane, the brute spring deformation that bends of rotation forerunner frame.
In above-mentioned a kind of simple and easy extension of back muscles exercising machine, the one-sided same vertical plane of described after-poppet is provided with upper and lower two and connects the limit wing outward.Above-mentioned two connect the limit wing and forerunner's frame composition square structure outward, make its bearing up-down force stable.
In above-mentioned a kind of simple and easy extension of back muscles exercising machine, described forerunner's frame is provided with the grip handle, and grip handle and forerunner's frame are hinged.Due to the arm of human body varying length, therefore can be by the rotation grip comfort level when regulating handle.
In above-mentioned a kind of simple and easy extension of back muscles exercising machine, described bench is provided with slot, and the after-poppet lower end is provided with adjusting screw(rod), and adjusting screw(rod) is provided with two setscrew nuts through slot and at afterbody, and described pair of setscrew nut is folded in the slot bottom.The rotation after-poppet can be realized the up-down adjustment in slot.
In above-mentioned a kind of simple and easy extension of back muscles exercising machine, described brute spring both sides are symmetrical arranged.
In above-mentioned a kind of simple and easy extension of back muscles exercising machine, the described outer even limit wing and forerunner's frame are hinged by detachable nut.Can be according to the different quantity that increase or reduce brute spring of the required strength of individual after the outer even limit wing and the dismounting of forerunner's frame.
Compared with prior art, this device volume is little, simple in structure, the adjustable joint of stretching dynamics, and can train deltoid muscle and latissimus dorsi simultaneously, be applicable to very much the average family Training Practicing.
The accompanying drawing explanation
The overall structure schematic diagram that Fig. 1 is a kind of simple and easy extension of back muscles exercising machine.
The up-down adjustment structural representation that Fig. 2 is a kind of simple and easy extension of back muscles exercising machine.
In figure, 1, bench; 2, brute spring; 3, forerunner's frame; 4, the outer limit wing that connects; 5, after-poppet; 6, detachable nut; 7, grip handle; 9, adjusting screw(rod); 10, two setscrew nuts; 11, slot.
The specific embodiment
As shown in Figure 1, simple and easy extension of back muscles exercising machine comprises bench 1, after-poppet 5, two forerunner's framves 3 and a series of brute spring 2, described after-poppet 5 is plugged on bench 1, all there is the outer limit wing 4 that connects in the both sides of after-poppet 5, the outer limit wing 4 same vertical plane one-sided in after-poppet 5 that connect is provided with upper and lower two, and connect the limit wing 4 outside one-sided two at after-poppet 5 up and down simultaneously by the hinged forerunner's frame 3 of detachable nut 6, described after-poppet 5, the outer limit wing 4 and the square guide frame of forerunner's frame 3 formation of connecting, bearing up-down force balance when square guide frame can make to pull, be equipped with a series of brute springs 2 in guide frame, and brute spring 2 is parallel to the ground, one head grafting after-poppet 5, other end grafting forerunner frame 3.Described brute spring 2 is symmetricly set on the right and left of after-poppet 5, can increase or reduce the quantity of brute spring 2 by dismantling lower forerunner's frame 3, with this, regulates flexible strength.
As shown in Figure 2, on forerunner's frame 3, be provided with grip 7, grip is hinged with forerunner's frame 3 in the horizontal direction 7, due to the arm varying length of human body, therefore can regulate 7 by the rotation grip.Above-mentioned bench 1 is provided with slot 11, and after-poppet 5 lower ends are provided with adjusting screw(rod) 9, adjusting screw(rod) 9 is provided with two bolts through slot 11 and at afterbody, and described pair of setscrew nut 10 is folded in slot 11 bottoms, rotates after-poppet 5 and can realize the up-down adjustment in slot 11.
