Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

Referring to fig. 1, 2, 3 and 5, a body-building stick comprises a stick body 1, two holding sleeves 2 are slidably sleeved on the stick body 1, a limiting sliding groove 5 is arranged on the side wall of the stick body 1 along the axial direction of the stick body, a limiting sliding block 4 corresponding to the limiting sliding groove 5 is fixedly connected on the inner wall of each holding sleeve 2, the limiting sliding block 4 is slidably connected in the limiting sliding groove 5, a piston cavity 6 is arranged in each holding sleeve 2, an air bag 3 is fixedly sleeved on the side wall of each holding sleeve 2 and communicated with the piston cavity 6, a piston rod 7 capable of horizontally moving is slidably connected in each piston cavity 6, a mounting groove 12 arranged along the axial direction of the stick body 1 is arranged on the side wall of the stick body 1, a plurality of straight teeth 11 are fixedly connected on the inner wall of the mounting groove 12 at equal intervals, the straight teeth 11 are integrally formed with the stick body 1, a containing groove 9 is arranged on one side wall of the piston rod 7 close to the stick body 1, run through on the inner wall of piston chamber 6 and be equipped with the bar trompil 13 that corresponds with pressing the mechanism position, the equal threaded connection in both ends of barred body 1 has the stop collar, can carry on spacingly to barred body 1, prevents that barred body 1 roll-off when taking exercise from gripping the cover 2.

According to the invention, the abutting mechanism comprises an abutting rod 10 which is rotatably connected to the inner wall of the accommodating groove 9, the abutting rod 10 is obliquely arranged, a first spring 8 is fixedly connected to the side wall of the abutting rod 10, the other end of the first spring 8 is fixedly connected to the inner wall of the accommodating groove 9, the end part of the abutting rod 10 penetrates through the strip-shaped opening 13 and abuts against the straight tooth 11, the bar body 1 is abutted and pressed through the abutting mechanism, the bar body 1 is further pushed to move, the gravity center of the bar body 1 is shifted to one side, further, the loaded arm is fully pressed, and the arm is subjected to load exercise.

Further, the middle part of the holding sleeve 2 is provided with an annular groove, the air bag 3 is wrapped outside the annular groove, and the surface of the air bag 3 is provided with anti-skid lines, so that the holding sleeve can effectively prevent skidding and is more comfortable to hold.

According to the invention, when an exerciser uses the body building bar, the two holding sleeves 2 are moved to the middle part of the bar body 1, two hands respectively hold the two holding sleeves 2, the arm is lifted to keep the bar body 1 horizontal, the holding sleeves 2 are tightly held by one hand to fully extrude the air bag 3, so that the piston rod 7 moves to a limit distance, the bar-shaped opening 13 limits the abutting rod 10, the abutting rod 10 rotates to be accommodated in the accommodating groove 9, the straight teeth 11 are not abutted any more, and the movement of the bar body 1 is not influenced, and the hand corresponds to the stressed arm.

At the moment, the hand on the other side extrudes the air bag 3 to push the piston rod 7 to move, when the air bag 3 is not extruded when the hand is loosened, the air bag 3 expands and recovers, so that the piston rod 7 moves and resets, the elastic force of the first spring 8 abuts against the abutting rod 10, the end part of the abutting rod 10 abuts against the straight teeth 11, the abutting rod 10 drives the bar body 1 to move for a certain distance, the gravity center of the bar body 1 is shifted to one side, and the hand corresponds to an operating arm.

The bar body 1 moves to one side to fully exert pressure on the stress arm, the stress arm is subjected to weight bearing exercise, namely, when the operation arm completes one-time grip training, the bar body 1 is pushed to move towards the operation arm for a distance, so that the gravity center of the bar body 1 deviates to one side, the weight bearing of the stress arm can be increased, the stress arm is fully exercised, the bar body 1 can move to one side continuously by repeatedly extruding the operation arm and loosening the air bag 3 until the bar body 1 is limited and can not move, so that the weight bearing of the stress arm reaches the maximum value, at the moment, the hand of the operation arm fully holds the holding sleeve 2 and fully extrudes the air bag 3, the hand of the stress arm can be repeatedly extruded and loosened to release the air bag 3, the bar body 1 can be reversely moved in the same way, namely, the hand grip of the arms and the hands at two sides can be alternately exercised, the movement of the bar body is realized by adopting the way of repeatedly extruding and loosening the air bag, and, the rocking of arm and health is very little when taking exercise, and then can not influence the balance of arm, and the exercise effect is better.

Example two

Referring to fig. 4, the difference between the second embodiment and the first embodiment is that in the present embodiment, a second spring 14 is disposed in the piston cavity 6, one end of the second spring 14 abuts against the end of the piston rod 7, an opening for placing the second spring 14 is disposed on the sidewall of the piston cavity 6, a sealing plug 15 is connected to the opening through an internal thread, and the sealing plug 15 abuts against the second spring 14.

When extrusion gasbag 3 promoted piston rod 7 and removed, the resistance that piston rod 7 removed can be increased to the elasticity of second spring 14, increase extrusion gasbag 3's resistance, make better training grip, and set up the training needs that sealing plug 15 can be according to different grip sizes, take out the second spring 14 of changing different elasticity, it is more nimble to use, it is better to temper the effect, when gasbag 3 resets the inflation and drives piston rod 7 and remove and reset, the elasticity through second spring 14 supports and presses piston rod 7, make piston rod 7 more fast reset, the supplementary excellent body 1 that promotes removes.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
