Technical Field

[0002] A gear mechanism is a device designed to prevent a mechanical device from accidentally rotating or reversing under certain circumstances. This mechanism is often used in engineering and mechanical design to ensure the safety and reliability of the system.
[0003] However, traditional anti-rotation and anti-return mechanisms usually use brakes and clutches to stop rotation, which makes the rotation ability invalid. However, this method will cause wear after long-term use, resulting in performance degradation, and the friction plate needs to be constantly replaced. At the same time, there will be a certain temperature rise during operation, which affects long-term use and overall safety. Therefore, in response to the above problems, a anti-rotation and anti-return gear mechanism is proposed. Utility Model Content

[0007] Furthermore, a proximal side of the blocking rod is in contact with the outer teeth of the second gear.
[0008] Furthermore, the limiting assembly includes two springs, and the two springs are arranged inside the movable column. The inner walls on both sides of the movable column are slidably connected to the limiting plate.
[0009] Furthermore, one end of the spring is fixedly connected to the left and right inner walls of the movable column, and the other end of the spring is fixedly connected to the far side of the limiting plate.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Reference Figures 1 to 4The utility model provides an embodiment: a gear mechanism for preventing rotation and retreating, including a mold 1, an opening 2 is provided in the middle of the mold 1, the setting of the opening 2 is convenient for placing the gear and the gear shaft, the middle of the opening 2 is rotatably connected with a gear 1 3, the front end of the gear 1 3 is fixedly connected to the outside with a gear 2 4, the gear 2 4 and the gear 1 3 are a whole, so that they rotate synchronously, the left and right inner walls of the mold 1 are fixedly connected with mounting plates 5, the inner wall of the adjacent side of the mounting plate 5 is rotatably connected with a rotating column 6, the outer side of the rotating column 6 is fixedly connected with a gear 3 7, the adjacent side of the rotating column 6 is fixedly connected with a movable column 8, the movable column 8 rotates on the mounting plate 5, the left and right sides of the movable column 8 are respectively rotatably connected to the adjacent side of the mounting plate 5, and the adjacent side of the movable column 8 is slidably connected with a blocking rod 9, The adjacent side of the blocking rod 9 is in contact with the external teeth of the gear 2 4. After the gear 2 4 rotates, one side of the blocking rod 9 is a slope, so that the external teeth of the gear 2 4 can rotate through the slope, and the other side of the blocking rod 9 is stuck with the teeth, so that the gear 2 4 will not move in the opposite direction. A limiting assembly is arranged inside the movable column 8, and the limiting assembly includes two springs 1001. The two springs 1001 are arranged inside the movable column 8, and the inner walls on both sides of the movable column 8 are slidably connected to the limiting plate 1002. One end of the spring 1001 is fixedly connected to the left and right inner walls of the movable column 8, and the other end of the spring 1001 is fixedly connected to the far side of the limiting plate 1002. The setting of the spring 1001 makes the movement of the blocking rod 9 more stable, and the limiting plate 1002 prevents the blocking rod 9 from leaving the inside of the movable column 8.
[0021] Working principle: when the gear shaft is rotating, gear 1 3 and gear 2 4 rotate synchronously. As gear 2 4 rotates, one side of the blocking rod 9 contacts the external teeth of gear 2 4. Under the rotation of gear 2 4, the blocking rod 9 moves backward continuously after being acted upon, thereby causing the spring 1001 to be squeezed. At the same time, after the rotation stops, in order to prevent gear 2 4 from reversing, the other side of the blocking rod 9 is engaged with the external gear of gear 2 4, so that gear 2 4 no longer moves in the opposite direction, thereby controlling the rotation of the shaft, thereby ensuring that the gear shaft no longer moves. In addition, the movable column 8 can also be rotated to reverse the direction of the blocking rod 9. At that time, the rotation direction of gear 2 4 can be changed, thereby conveniently preventing the gear from rotating in the opposite direction, thereby ensuring the stability of the gear.
[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
