Description

Technical Field

[0001] The utility model belongs to the technical field of trainers, and particularly refers to a waist stretcher. Background Art

[0002] The waist is an important part of the human body. Bending down to pick up things or carrying heavy objects requires the waist to exert force. If the usual sitting posture is not good or excessive lifting of heavy objects is done, it is very easy to cause damage to the waist. In severe cases, even scientific and technological means in the hospital are needed for treatment and recovery. As the saying goes, it takes a hundred days to recover from a bone injury. To restore the natural state before after hurting the waist, maintenance and recovery training are very crucial. Usually, doctors will recommend moving back and forth before bending down and straightening the chest. However, if a newly treated person does not have a companion to support them all the time, it is very easy for them to be unable to straighten up or even fall, and in severe cases, they may be re-injured. Moreover, it is very time-consuming for the companion to accompany all the time. Therefore, there is a need for a trainer that can replace the companion and help the user complete the process of bending down to straightening up during waist training. Summary of the Invention

[0003] The purpose of the utility model is to provide a trainer with a simple structure that can replace the companion and help the user complete the process of bending down to straightening up during waist training.

[0004] The purpose of the utility model is achieved as follows:

[0005] A waist stretcher includes a vertically arranged connecting pipe, an upper support rod arranged at the upper end of the connecting pipe, and a lower bottom rod arranged at the lower end of the connecting pipe. Foot stepping parts are arranged at both ends of the lower bottom rod. The connecting pipe includes a first connecting pipe and a second connecting pipe. The upper support rod is arranged at the upper end of the first connecting pipe, and the lower bottom rod is arranged at the lower end of the second connecting pipe. The first connecting pipe is arranged outside the second connecting pipe. An elastic member is further arranged inside the second connecting pipe. The lower end of the elastic member is connected to the lower bottom rod, and the upper end of the elastic member is connected to the upper support rod. Holding the upper support rod upward can drive the elastic member to expand. After reducing the force of holding the upper support rod, the elastic member can contract to drive the upper support rod downward, thereby making an up-and-down reciprocating motion.

[0006] Further, a first through hole is formed in the first connecting pipe. The upper support rod passes through the first through hole, and the upper support rod can move horizontally and / or rotate in the first through hole.

[0007] Further, a second through hole is formed in the lower bottom rod. The second connecting pipe passes through the second through hole, and the second connecting pipe can rotate around the lower bottom rod.

[0008] Further, a plurality of annular convex parts are further arranged on the upper support rod.

[0009] Furthermore, the first connecting pipe and the second connecting pipe are hollow inside. An upper sealing cover is also provided above the first connecting pipe, and a lower sealing cover is provided below the second connecting pipe.

[0010] Furthermore, a connecting hole is formed in the foot stepping part, and the foot stepping part is connected to the lower bottom rod through the connecting hole.

[0011] Furthermore, the elastic member is a spring. An upper hook is provided at the upper end of the spring, and a lower hook is provided at the lower end of the spring. The spring is hooked to the upper support rod through the upper hook and hooked to the lower bottom rod through the lower hook.

[0012] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0013] The present utility model is a trainer that can replace accompanying personnel and help the user complete the process of bending down to straightening the waist during waist training. The user can operate this trainer alone relying on his own body. When the user holds the upper support rod with his hand and the human body is in a bent state, when the upper support rod is lifted upward, the upper support rod drives the elastic member to stretch and gradually tighten. The first connecting pipe moves upward with the upper support rod and gradually moves away from the second connecting pipe. At this time, the distance between the two ends of the first connecting pipe and the second connecting pipe is lengthened. Along with the upward movement, the user gradually changes from a bent state to a straight state, and at this time the human body is in a standing state. After the user reduces the force pulling the upper support rod, the upper end of the elastic member pulls the upper support rod downward, and the elastic member gradually contracts from the tightened state. The first connecting pipe moves downward with the upper support rod, and the distance between the two ends of the first connecting pipe and the second connecting pipe will become shorter. Along with the downward movement, the human body gradually changes from a standing state to a bent state. By making reciprocating movements between standing and bending, and bending and standing, it can help with rehabilitation training. Moreover, the user steps on the foot stepping part, the foot stepping part contacts the ground, and the hand holds the upper support rod. There are support points at both the upper and lower ends of the human body, so it will not fall easily and does not require the help of accompanying personnel and can be completed alone. The foot stepping part can also be made in the shape of a foot to fit the user's sole better. An elastic member is also provided on the second connecting pipe of the present utility model, and the elastic force encountered by the user during the pulling process can better help the user recover strength.

[0026] The utility model is a trainer that can replace accompanying personnel and help the user complete the process of bending down to straightening the waist during waist training. The user can operate this trainer alone relying on their own body. The user holds the upper support rod 2 with their hand. At this time, the human body is in a bent state. When the upper support rod 2 is lifted upward, the upper support rod 2 drives the elastic member 7 to stretch and gradually tighten. The first connecting pipe 5 moves upward with the upper support rod 2 and gradually moves away from the second connecting pipe 6. At this time, the distance between the two ends of the first connecting pipe 5 and the second connecting pipe 6 is lengthened. The user also gradually changes from a bent state to a straight state with the upward movement. At this time, the human body is in a standing state. After the user reduces the force pulling the upper support rod 2, the upper end of the elastic member 7 pulls the upper support rod 2 downward, and the elastic member 7 gradually contracts from the tightened state. The first connecting pipe 5 moves downward with the upper support rod 2, and the distance between the two ends of the first connecting pipe 5 and the second connecting pipe 6 will become shorter. The user then gradually changes from a standing state to a bent state with the downward movement. By repeatedly standing up and bending down, and bending down and standing up to make reciprocating movements, it can help with rehabilitation training. Moreover, the user steps on the foot stepping part 4, the foot stepping part 4 contacts the ground, and the hand holds the upper support rod 2. There are support points at both the upper and lower ends of the human body, so it is not easy to fall, and there is no need for the help of accompanying personnel, and it can be completed alone. The foot stepping part 4 can also be made in the shape of a foot to fit the user's sole more conveniently. The second connecting pipe 6 of the utility model is also provided with an elastic member 7, and the elastic force encountered by the user during the pulling process can better help the user recover their strength.

[0027] Preferably, a first through hole 8 is formed in the first connecting pipe 5, and the upper support rod 2 passes through the first through hole 8.
