[0026] Example 1

[0027] Reference Figures 1 to 3 , which is the first embodiment of the utility model, provides an impact-resistant reduction gearbox, which includes a reduction assembly 100 and a protection assembly 200, wherein the reduction assembly 100 includes a reduction gearbox 101, an input shaft 102 arranged on the reduction gearbox 101, and an output shaft 103 arranged on the reduction gearbox 101; the protection assembly 200 is arranged outside the output shaft 103, and includes a rotating cylinder 201 connected to the output shaft 103, a clamp 202 sleeved in the rotating cylinder 201, a sliding cylinder 203 sleeved outside the rotating cylinder 201, a rotating ring 204 sleeved outside the sliding cylinder 203, a rotating cylinder 205 fixed to the rotating ring 204, and a fixed cylinder 206 connected to the rotating cylinder 205.

[0028] A connecting rod 103a extends from the center of the output shaft 103, and grooves 103b are equidistantly provided on the side wall of the output shaft 103. The inner wall of the rotating cylinder 201 is rotatably connected to the output shaft 103 through the grooves 103b. The bottom of the clamp 202 is cylindrical, and the end is horn-shaped. A plurality of pressing sheets 202a are provided at the end of the clamp 202, and there are gaps between the pressing sheets 202a. The end of the inner wall of the rotating cylinder 201 is horn-shaped, and the pressing sheets 202a can be embedded in the rotating cylinder 201, and the connecting rod 103a passes through the clamp 202. The sliding cylinder 203 is sleeved on the outside of the rotating cylinder 201, and a through hole 203a is provided in the center of the sliding cylinder 203, and the connecting rod 103a extends from the through hole 203a. The rotating ring 204 is annular, and the rotating ring 204 is rotatably connected to the sliding cylinder 203, and a ball 204a is also provided in the rotating ring 204. The rotating cylinder 205 is fixedly connected to the rotating ring 204. The rotating cylinder 205 is sleeved on the outside of the sliding cylinder 203. The rotating cylinder 205 is also provided with a handle 205a. The fixed cylinder 206 is sleeved on the outside of the rotating cylinder 201. The rotating cylinder 201 is rotatably connected to the fixed cylinder 206. The fixed cylinder 206 is fixed to the side wall of the reduction box 101 by bolts 206a. The outer wall of the fixed cylinder 206 is provided with a thread 206b. The rotating cylinder 205 is rotatably connected to the fixed cylinder 206 by the thread 206b.

[0029] During use, the input shaft 102 provided on the reduction box 101 is a driving shaft connected to other power sources such as a motor, and the reduction box 101 provides high torque rotation through the output shaft 103. The output shaft 103 is connected to other devices through a connecting rod 103a. The connecting rod 103a is the central axis protected in the utility model, and a protection component 200 is provided outside the connecting rod 103a; the connecting rod 103a extends from the output shaft 103 to the outside of the protection component 200. When reinforcing the connecting rod 103a, the outer rotating cylinder 205 is rotated by the handle 205a. Since the fixed cylinder 206 is fixed to the side wall of the reduction box 101 by bolts 206a, the fixed cylinder 206 is stationary, and the rotating cylinder 205 can move back and forth on the fixed cylinder 206 through the thread 206b. When reinforcing, the handle 205a should be operated to make the rotating cylinder 205 close to the fixed cylinder 206. When the fixed cylinder 206 moves to the left, the rotating ring 204 fixedly connected to the rotating cylinder 205 moves to the left synchronously. The rotating ring 204 is sleeved on the outside of the sliding cylinder 203. A limit plate 203b is also provided at the bottom of the sliding cylinder 203. The rotating ring 204 can push the limit plate 203b to make the sliding cylinder 203 move to the left synchronously. The left movement of the sliding cylinder 203 can squeeze the pressing piece 202a at the end of the clamp 202, so that the pressing piece 202a is received in the rotating cylinder 201. Due to the trumpet-shaped inner wall in the rotating cylinder 201, the pressing piece 202a will be tightened inwardly to reinforce the connecting rod 103a, thereby increasing the impact resistance of the output shaft. When the output shaft 103 rotates, since the rotating cylinder 201 is rotatably connected to the output shaft 103 through the groove 103b, the reinforced components will not affect the rotation of the output shaft 103 and the connecting rod 103a. When the reinforcement needs to be released, just reverse the above steps.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
