Twisting machine structure improvement

This creation is about the improvement of a twisting machine structure, especially a twisting machine driven by a gear set, which has the advantages of strong structural rigidity and easy assembly.

According to the current, there are quite a lot of exercise equipments on the market. For example, treadmills, horse-riding machines, etc. can be used for various fitness or exercise, but the construction of these exercise equipments is quite complicated and bulky, and only sports a single body. Specific parts (such as legs, arms), so these sports equipment are not popular, it is a pity.

In order to solve the above problems, a manufacturer has developed a "twisting type exercise apparatus" such as the new patent No. M453520 of the Republic of China, which includes a base having a spindle for rotatably erecting a handle, and a pulley disposed on the handle and opposite Rotating on the mandrel, a carrier has a rotating shaft that is rotatably mounted on the base, another pulley is disposed on the base and rotatable relative to the rotating shaft, and a connecting member is coupled to the two pulleys, so that the seat and the handle can be In linkage with each other, the connecting member may include two rope bodies arranged in a cross shape such that the handle and the seat body rotate in different directions.

However, the conventional structure has the following disadvantages:

1. The conventional structure mainly produces a back and forth swinging effect by arranging a linked rope body on two pulleys, but the rope body needs to be restrained on the pulley, and the rope body must be pulled to a certain width to be assembled on the pulley, which is not only laborious. It also increases the complexity of assembly.

2. The conventional structure is mainly transmitted through the rope body. It can be understood that the long-term friction between the rope body and the pulley will cause the rope body to gradually relax, and the effect of the synchronous movement of the handle and the seat body is lost, but when the rope body is replaced, the assembly as described above is caused. The problem arises.

Another prior case of the Republic of China, No. 540396, "The Structure of a Swing Machine", is mainly characterized in that the opposite ends of the T-shaped frame have freely rotatable circular pedals, so that the swing machine can select a T-shaped frame. The large circular diameter is twisted, and the small round diameter of the single side circular pedal seat can be synchronously matched with the large circular power double shaft point torsional movement.

However, the disadvantages mentioned above are that the armrest frame is fixed and twisted relative to the T-shaped frame. However, the twisting force and the twisting angle are limited by the strength of the feet, and the twisting is less smooth, and the pedal is free. Rotating, the two circular pedals are also idling under the rotation of the T-shaped frame, so that the rotation angles of the two circular pedals are very small, and the effect of actually twisting the waist cannot be achieved.

Furthermore, the upper body of the body cannot be rotated, so that the feet of the lower body are powered, and the thrust is more difficult. Due to the force applied by the feet, the rotation direction of the circular pedal is the same as the rotation direction of the T-shaped frame. No twisting effect.

The main purpose of this creation is to improve the complexity of the conventional structure assembly and the wear problems caused by the rope body; the main technique is to provide a base, a twisting assembly, a transmission group and a pedal group.

The base of the base is provided with two sets of fixed shafts, one is an active fixed shaft and the other is a fixed fixed shaft, and the two fixed shafts provide the transmission assembly.

The transmission group is composed of a driving gear and a linkage gear, and the transmission group is respectively assembled on the active fixed shaft and the interlocking fixed shaft of the base, and the driving gear and the linking gear respectively have a central hole and a connecting hole, and then The driving gear and the interlocking gear are respectively engaged with each other when the active fixed shaft and the fixed fixed shaft are assembled.

The twisting assembly is assembled above the driving gear, the twisting assembly has a handle and a rod having a bent angle, the handle is combined on the top of the rod, the rod has a flat end, and the rod has a flat end The wing portions are symmetrically arranged on the two sides, and the pivoting effect is achieved by interlocking the rod body with the connecting hole of the driving gear.

The pedal set is mounted above the linkage gear, and a sleeve is disposed under the pedal set, and the sleeve is fixed between the linkage gear and the pedal group through a coupling bolt, so that the pedal group is driven by the linkage gear Produce linkage.

According to this, when the twisting assembly generates the left and right swinging, the driving gear generates a pivoting motion, and the driving gear meshes with the interlocking gear to cause the interlocking gear to rotate relative to the driving gear rotation direction. The interlocking gear drives the pedal gear to generate a synchronous action.

Through the above structure, this creation can obtain the following advantages:

1. The transmission group of the present invention is formed by the driving gear and the interlocking gear, and the transmission effect is achieved by the mutual meshing of the two, since the gear only needs to be directly sleeved on the fixed shaft, Compared with the conventional structure, the creation has the advantages of convenient assembly and long service life.

2. The pedal group is provided with two sets of mutually symmetrical assembly slots, and each of the assembly slots is provided with a shaft hole, and the pedal group further comprises two sets of rotating discs, and an axis is extended below the rotating disc. The shaft hole is assembled in the assembly groove so that the rotating disk is rotated.

4. The driving gear and the central hole of the interlocking gear, and at least one bearing in the sleeve, reduce the friction generated by the driving gear, the interlocking gear and the active fixed shaft and the fixed fixed shaft.
