[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

[0020] Example 1, please refer to Figures 1-4, the present invention provides a technical solution: a protective gear with anti-backward rotation function, including a gear body 1 and a protective component 2.
[0021] Among them, the protective component 2 includes: A protective ring plate 201, which is fixedly connected to the middle of the front and back of the gear body 1. A rotating ring 202 is rotatably connected to the inner wall of the protective ring plate 201.

A rotating circular groove penetrating through the front and back is opened in the middle of the gear body 1, and a ratchet tooth 204 is fixedly connected in the rotating circular groove. By setting the protective ring plate 201, the rotating circular groove inside the gear body 1 can be protected.
[0022] A chute is provided inside the rotating ring 202, and the rotating ring 202 is slidably connected to the protective ring plate 201 through the chute, and the rotating ring 202 can rotate inside the protective ring plate 201.
[0023] By setting that the gear body 1 has the function of preventing backward rotation, in many mechanical devices, such as airplanes, automobiles, ships, and industrial equipment, etc., the backward rotation of the gear may cause serious safety accidents. The function of preventing backward rotation can ensure that these devices are safer during operation and reduce the risks caused by the reverse rotation of the gear.
[0024] Example two, please refer to Figures 1-8 , on the basis of Example one, the present invention provides a technical solution: it further includes a driven component 3, and the driven component 3 is composed of a receiving groove 301, a positioning frame 302, a ratchet block 303, and an extension block 304.
[0025] The receiving groove 301 is opened on the outer wall of the driving cylinder 203, the positioning frame 302 is fixedly connected to the outside of the driving cylinder 203 and is located on the front and back sides of the receiving groove 301. The ratchet block 303 is rotatably connected to the middle of the positioning frame 302, and the extension block 304 is fixedly connected to the bottom of the ratchet block 303. The ratchet block 303 can rotate in the middle of the positioning frame 302.
[0026] It further includes a limiting component 4, and the limiting component 4 is composed of a rotating sleeve 401, a rotating insertion block 402, an adjusting plate 403, a limiting plate one 404, and a limiting plate two 405.
[0027] The rotating sleeve 401 is arranged inside the driving cylinder 203, the rotating insertion block 402 is fixedly connected to the outside of the rotating sleeve 401, the adjusting plate 403 is fixedly connected to the front and back right sides of the rotating insertion block 402, the limiting plate one 404 is fixedly connected to the inner wall of the driving cylinder 203, the limiting plate two 405 is fixedly connected to the inner wall of the driving cylinder 203 and is located on the front and back sides of the receiving groove 301. The limiting plate one 404 and the limiting plate two 405 can limit the adjusting plate 403.
[0028] Both the front and back of the extension block 304 are fixedly connected with limiting arc plates. The cooperation between the limiting arc plates and the extension block 304 can limit the ratchet block 303 and the extension block 304.
[0029] Both the ratchet block 303 and the extension block 304 are located inside the receiving groove 301, and the ratchet block 303 and the extension block 304 can rotate within the receiving groove 301.
[0030] Lubricating oil is provided on the outside of the ratchet block 303, and when the ratchet block 303 rotates, the lubricating oil can be flung onto the surface of the rotating sleeve 401.
[0031] When the device needs to rotate normally, an external rotating rod is inserted into the rotating sleeve 401 to make the rotating sleeve 401 rotate. When the rotating sleeve 401 rotates, the rotating insertion block 402 and the adjusting plate 403 on the rotating sleeve 401 can rotate synchronously. When the adjusting plate 403 rotates, the rotating insertion block 402 can rotate to the lower side of the extension block 304, and the rotating insertion block 402 can arch the extension block 304 upward. At this time, the ratchet block 303 rotates upward around the positioning frame 302 within the receiving groove 301, and can rotate the extension block 304. At this time, the limiting arc plate on the extension block 304 is stuck on the lower side of the receiving groove 301, which can limit the extension block 304 and the ratchet block 303. At the same time, the ratchet block 303 rotates to the outside of the driving cylinder 203, and the adjusting plate 403 on the rotating insertion block 402 contacts the second limiting plate 405. Subsequently, continue to control the rotating sleeve 401 to continue rotating, which can make the adjusting plate 403 on the rotating insertion block 402 squeeze the second limiting plate 405 and make the adjusting plate 403 push the second limiting plate 405. At this time, the rotating sleeve 401, the driving cylinder 203, and the ratchet block 303 rotate synchronously, so that the ratchet block 303 is inserted into the internal ratchet teeth 204 of the gear body 1, and the ratchet block 303 can push the ratchet teeth 204 to rotate, enabling the gear body 1 to rotate.
[0032] When the rotating sleeve 401 rotates in reverse, the rotating insertion block 402 and the adjusting plate 403 on the rotating sleeve 401 can rotate synchronously in the reverse direction, making the rotating insertion block 402 and the adjusting plate 403 rotate in the reverse direction. At this time, the rotating insertion block 402 moves out from below the ratchet block 303. At this time, the ratchet block 303 and the extension block 304 automatically fall back into the receiving groove 301. At the same time, the rotating insertion block 402 and the adjusting plate 403 on the rotating sleeve 401 rotate synchronously, making the adjusting plate 403 contact the first limiting plate 404, and the first limiting plate 404 limits the adjusting plate 403. At the same time, the rotating sleeve 401 can push the driving cylinder 203 to rotate in the reverse direction. Since the ratchet block 303 and the extension block 304 are received inside the driving cylinder 203, when the rotating sleeve 401 rotates in the reverse direction, the ratchet block 303 does not contact the ratchet teeth 204, and the rotating sleeve 401 can push the driving cylinder 203 to rotate idly inside the gear body 1, preventing the gear body 1 from rotating in reverse.
[0033] When the rotating sleeve 401 idles inside the driving cylinder 203, it can throw out the lubricating oil outside the ratchet block 303 and make it swing onto the surface of the ratchet 204, enabling it to have the function of automatic lubrication and maintenance.
[0034] The reverse rotation of the rotating sleeve 401 inside the gear body 1 can prevent the gear body 1 from reversing. The reverse rotation of the gear body 1 may damage the transmission system of the equipment, such as gear wear, bearing damage, etc. The function of preventing reverse rotation can reduce these damages, extend the service life of the equipment, and reduce the maintenance cost.
[0035] When the rotating sleeve 401 idles inside the driving cylinder 203, it can throw out the lubricating oil outside the ratchet block 303 and make it swing onto the surface of the ratchet 204. When the ratchet block 303 rotates in the reverse direction, the lubricating oil can be effectively swung onto the surface of the ratchet 204, which enhances the lubrication effect between the ratchets 204. The presence of the lubricating oil can reduce the friction coefficient between the ratchets 204, reduce wear, and contribute to the smooth transmission of the gear body 1.
