As shown in Figures 1-7, a treadmill includes:

base 1;

Handrail 2, a horizontal bar 21 is installed on the handrail 2;

A rotating shaft 3, the rotating shaft 3 is rotatably connected with the base 1, and the bottom of the armrest 2 is fixed on the rotating shaft 3;

The rotating shaft drive assembly, which is installed on the base 1, is used to drive the rotation of the rotating shaft 3;

The rotating shaft locking assembly is installed on the base 1 to limit the rotation of the rotating shaft 3 .

In this way, the handrail 2 is provided with a horizontal bar 21, and the handrail 2 and the horizontal bar 21 are combined to form a ladder, so that the treadmill can be used as a ladder. Thereby, the inclination angle of the ladder is controlled. During adjustment, the rotating shaft drive assembly urges the rotating shaft 3 to rotate, so that the handrail 2 fixed on the rotating shaft 3 also rotates to a certain extent, and then the rotating shaft locking assembly is used to restrict the rotation of the rotating shaft 3, so that the handrail 2 fixed at a specific angle.

In addition, the rotating shaft drive assembly includes a transmission assembly, the transmission assembly is provided with two groups, and the transmission assembly includes:

The first gear 4, the first gear 4 is fixed on the rotating shaft 3;

The rack 5, the rack 5 is slidably installed on the base 1, and the rack 5 meshes with the first gear 4;

The screw nut 6, the screw nut 6 is fixed on the rack 5, and the screw nut 6 is a ball nut;

The lead screw 7, the lead screw 7 passes through the lead screw nut 6 and cooperates with the lead screw nut 6, and the lead screw 7 is a ball screw;

The support base 8, the screw rod 7 is rotatably mounted on the support base 8, and the screw rod 7 and the support base 8 are axially fixed;

In addition, the rotating shaft drive assembly also includes a motor 9, a pulley 10 and a transmission belt 11. The output shaft of the motor 9 is connected to the lead screw 7 in one of the transmission assemblies, and the motor 9 is fixed on the base 1; the pulley 10 is provided with two, two The pulleys 10 are respectively fixed on the screw rod 7 , and the transmission belt 11 is matched with the pulleys 10 .

In this way, when the angle of the handrail 2 is adjusted, the motor 9 is activated, and the rotation of the output shaft of the motor 9 drives the rotation of the screw 7. Since the pulley 10 and the transmission belt 11 are connected between the two screw rods 7, one of the screws The rotation of the rod 7 drives the rotation of the other screw 7, the rotation of the screw 7 drives the screw nut 6 to move axially along the screw 7, and the movement of the screw nut 6 drives the sliding of the rack 5, and the rack 5 The sliding of the first gear 4 drives the rotation of the first gear 4 , the rotation of the first gear 4 drives the rotation of the rotating shaft 3 , and the rotation of the rotating shaft 3 finally drives the rotation of the armrest 2 , thereby adjusting the angle of the armrest 2 .

In addition, the base is provided with a guide seat 12 , and the rack 5 is slidably matched with the guide seat 12 . Specifically, two guide seats 12 are arranged opposite to each other. A groove is provided, and the protrusion fits in the groove, so that the rack 5 can slide freely.

In addition, the control button 13 is also included. The control button 13 is electrically connected to the motor 9 , and the control button 13 is installed on the base 1 . In this way, the startup and shutdown of the motor 9 can be conveniently controlled.

In addition, the shaft locking assembly includes a second gear 14 and a locking member 15, the second gear 14 is fixed on the screw rod 7, the locking member 15 is installed on one side of the second gear 14, and the locking member 15 faces the second gear 14. One side of the gear 14 is provided with a latching tooth 15 a that engages with the second gear 14 , and the locking member 15 is fixedly connected to the base 1 . In this way, before adjusting the angle of the armrest 2, first disassemble the locking member 15 to keep the locking member 15 away from the second gear 14. After the angle of the armrest 2 is adjusted in place, move the locking member 15 close to the second gear 14 and make the locking member 15 close to the second gear 14. The locking teeth 15a on the locking member 15 are engaged with the second gear 14, and then the locking member 15 is fixed again. In this way, the rotation of the ball screw 7 is restricted. After the screw 7 is fixed, the screw nut 6 will not move, the rack 5 will not move, the first gear 4 will not be able to rotate, and the rotating shaft 3 will be blocked. It is fixed, and finally the armrest 2 is fixed at a specific angle.

In addition, the shaft locking assembly further includes a threaded connection member 16, the base 1 is provided with a fourth through hole and a threaded hole in communication with the fourth through hole, the locking member 15 is slidably installed in the fourth through hole, and the locking member The 15 is provided with a fifth through hole, the threaded connector 16 is installed in the threaded hole, and the threaded connector 16 is inserted into the fifth through hole. In this way, the threaded connecting piece 16 can easily fix the locking piece 15 on the base 1. When disassembling, it is only necessary to turn the threaded connecting piece 16 to pull out the threaded connecting piece 16 from the locking piece 15, and then slide the locking piece 15 to lock it. Piece 15.

In addition, there are two sets of rotating shaft locking assemblies. In this way, the locking strength of the rotating shaft locking assembly on the rotating shaft can be enhanced, and the stability can be increased.

In addition, it also includes a support assembly, the support assembly is fixed on the base 1 , and the base 1 and the support assembly are located on two sides of the armrest 2 respectively. When the armrest 2 rotates to a certain angle, the human body stands on the horizontal bar 21 of the armrest 2, so that the connection between the base 1 and the armrest 2 is rotated due to the force, and the human body cannot stand on the horizontal bar 21 normally, so that the There are security risks. However, when the support components are added, the base 1 will not be able to rotate, thereby avoiding potential safety hazards and increasing stability.

In addition, the support assembly includes a support rod 17 and a connecting piece 18. There are two support rods 17, and a chute is provided on the base 1. The two support rods 17 are slidably installed in the chute respectively. A through hole 17a, there are at least two first through holes 17a, the base 1 is provided with a second through hole 1a that communicates with the first end of the chute, there are at least two second through holes 1a, the connecting piece 18 is inserted into the first through hole 17a and the second through hole 1a, thereby connecting the base 1 and the support rod 17.

In this way, when fixing the support rod, it is only necessary to align the first through hole 17a and the second through hole 1a, and then insert the connecting piece 18, which is convenient for installation and disassembly.

In addition, the base 1 is provided with a third through hole 1b that communicates with the second end of the chute, at least two third through holes 1b are provided, and the connecting piece 18 is inserted into the first through hole 17a and the third through hole at the same time 1b, the support rod 17 is located in the chute. In this way, the support rod 17 can be placed in the base 1, so as to protect the support rod 17 when the support rod 17 is not in use, and at the same time increase the aesthetics.

In addition, a reinforcing rod 19 is also included, and the reinforcing rod 19 is connected between the two supporting rods 17 . In this way, the overall strength of the support rod 17 can be enhanced.

In a word, the above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the present invention. within the scope of protection.
