[0020] The injection mechanism 2 includes an injection cylinder 201, a piston 202, a first side tube 203, a first sliding block 204, a first spring 205, a first valve core 206, a first position limiting tube 207, a first valve 208, a second side tube 209, a second sliding block 210, a second spring 211, a second valve core 212, a second position limiting tube 213, a second valve 214, a connecting block 215, an output tube 216 and an injection head 217. The injection cylinder 201 is attached to one end of the inner wall of the barrel body 1, the piston 202 is slidably connected to one side of the inner wall of the injection cylinder 201, the first side tube 203 is fixedly connected to one side of the injection cylinder 201, the first sliding block 204 is slidably connected to one side of the inner wall of the first side tube 203, and one end of the first sliding block 204 is fixedly connected to A first spring 205 is provided, one end of the first sliding block 204 is fixedly connected to a first valve core 206, the other end of the first spring 205 is fixedly connected to a first position limiting tube 207, the other side of the first position limiting tube 207 is fitted with a first valve 208, one side of the injection cylinder 201 is fixedly connected to a second side tube 209, one side of the inner wall of the second side tube 209 is slidably connected to a second sliding block 210, one end of the second sliding block 210 is fixedly connected to a second spring 211, one end of the second sliding block 210 is fixedly connected to a second valve core 212, the other end of the second spring 211 is fixedly connected to a second position limiting tube 213, one side of the second position limiting tube 213 is fitted with a second valve 214, one end of the second side tube 209 is fixedly connected to a connecting block 215, one end of the connecting block 215 is fixedly connected to an output pipe 216, and the other end of the output pipe 216 is fixedly connected to an injection head 217. During use, the lubricant in the barrel body 1 will enter the injection mechanism 2. When the piston 202 moves upward, due to the reduction of the internal pressure of the injection cylinder 201, the air pressure outside the injection cylinder 201 will squeeze the first sliding block 204 and the second valve 214, and the second valve 214 will fit with the second limiting tube 213 and will not move, while the first sliding block 204 will slide in the first side tube 203, and the sliding of the first sliding block 204 will drive the first valve core 206 to move, and the movement of the first valve core 206 will drive the first valve 208 to move, so that the lubricant outside the injection cylinder 201 will be injected from The first limiting tube 207 is sucked into the injection cylinder 201. When the piston 202 moves downward, due to the increase in the internal pressure of the injection cylinder 201, the pressure inside the injection cylinder 201 will squeeze the first valve 208 and the second sliding block 210. The second sliding block 210 will fit with the first limiting tube 207 and will not move, while the second sliding block 210 will slide in the second side tube 209. The sliding of the second sliding block 210 will drive the second valve core 212 to move, and the movement of the second valve core 212 will drive the second valve 214 to move, so that the lubricant inside the injection cylinder 201 will be pushed into the output tube 216 from the second side tube 209 and output from the injection head 217, thereby achieving the purpose of automatic quantitative injection of lubricant.

[0021] Further, the first valve 208 is fitted with the first position-limiting tube 207 through the first side tube 203, the first sliding block 204, the first spring 205, and the first valve core 206.

By setting the first valve 208, the first side tube 203, the first sliding block 204, the first spring 205, the first valve core 206, and the first position-limiting tube 207, the first spring 205 can move the first sliding block 204 , the first valve core 206 and the first valve 208 are reset, thereby ensuring that the injection cylinder 201 can normally absorb the lubricant and improving the efficiency of the lubricant use; through the arrangement of the second valve 214, the second side tube 209, the second sliding block 210, the second spring 211, the second valve core 212 and the second limiting tube 213, the second spring 211 can allow the second sliding block 210, the second valve core 212 and the second valve 214 to be reset, thereby ensuring that the injection cylinder 201 can normally transport the lubricant to the injection head 217 and ensuring that the lubrication effect is just right.

[0022] Furthermore, the material of the first valve 208 and the second valve 214 is rubber, and the first valve core 206 is slidably connected to the first side tube 203. By setting the first valve 208 and the second valve 214 made of rubber material, the sealing performance of the first side tube 203 and the second side tube 209 can be better, thereby ensuring the automatic quantitative injection of lubricant into the injection cylinder 201. By setting the first valve core 206 and the first side tube 203, the lubricant can be smoothly input into the interior of the injection cylinder 201, avoiding the problem of inaccurate injection amount caused by human factors.

[0023] Furthermore, the second valve core 212 is slidably connected to the second side tube 209. Through the setting of the second valve core 212 and the second side tube 209, it can be ensured that the injection cylinder 201 can output the lubricant smoothly, ensure that the lubricant is injected according to the set amount, and avoid waste or shortage of lubricant.

[0024] Furthermore, the loading and unloading mechanism 3 includes a cover 301, a fixed block 302, a cylinder 303 and a transmission shaft 304. The cover 301 is threadedly connected to one side of the surface of the barrel body 1, one end of the cover 301 is fixedly connected to the fixed block 302, one side of the fixed block 302 is fixedly connected to the cylinder 303, and the output end of the cylinder 303 is fixedly connected to the transmission shaft 304. During use, when lubricant needs to be injected, the lubricant can be poured into the barrel body 1 first, and then the cover 301 together with the injection mechanism 2 is placed into the barrel body 1. After determining the position, the cover 301 and the barrel body 1 are rotated and tightened to ensure the normal injection of the lubricant.

[0025] Furthermore, the piston 202 is slidably connected to the injection cylinder 201 via the transmission shaft 304. Through the arrangement of the piston 202, the transmission shaft 304 and the injection cylinder 201, the cylinder 303 can drive the piston 202 to move, thereby ensuring that the automated quantitative lubricant injection device can accurately inject lubricant according to the set amount.

[0026] Working principle: During use, when it is necessary to inject lubricant, the lubricant can be first poured into the barrel body 1, and then the cover 301 together with the injection mechanism 2 can be placed into the barrel body 1. After the position is determined, the cover 301 and the barrel body 1 are rotated and tightened to ensure the normal injection of the lubricant. The lubricant in the barrel body 1 will enter the injection mechanism 2. When the piston 202 moves upward, due to the reduction of the internal pressure of the injection cylinder 201, the air pressure outside the injection cylinder 201 will squeeze the first sliding block 204 and the second valve 214, and the second valve 214 will fit with the second limiting tube 213 and will not move, and the first sliding block 204 and the second valve 214 will fit with the second limiting tube 213 and will not move. The first sliding block 204 will slide in the first side tube 203, and the sliding of the first sliding block 204 will drive the first valve core 206 to move, and the movement of the first valve core 206 will drive the first valve 208 to move, so that the lubricant outside the injection cylinder 201 will be sucked into the injection cylinder 201 from the first limit tube 207. When the piston 202 moves downward, due to the increase in the pressure inside the injection cylinder 201, the pressure inside the injection cylinder 201 will squeeze the first valve 208 and the second sliding block 210, and the second sliding block 210 will fit with the first limit tube 207 and will not move, and the second sliding block 210 The first valve 208, the first side tube 203, the first sliding block 204, the first spring 205, the first valve core 206 and the first limit tube 207 are configured so that the first sliding block 205 can move the first sliding block 209, and the second valve core 212 can move. The movement of the second valve core 212 can drive the second valve 214 to move, so that the lubricant in the injection cylinder 201 can be pushed into the output pipe 216 from the second side tube 209 and output from the injection head 217, thereby achieving the purpose of automatic quantitative injection of lubricant. Through the arrangement of the first valve 208, the first side tube 203, the first sliding block 204, the first spring 205, the first valve core 206 and the first limit tube 207, the first spring 205 can move the first sliding block 209. 4. The first valve core 206 and the first valve 208 are reset, thereby ensuring that the injection cylinder 201 can normally absorb the lubricant, thereby improving the efficiency of lubricant use. Through the arrangement of the second valve 214, the second side tube 209, the second sliding block 210, the second spring 211, the second valve core 212 and the second limiting tube 213, the second spring 211 can reset the second sliding block 210, the second valve core 212 and the second valve 214, thereby ensuring that the injection cylinder 201 can normally transport lubricant to the injection head 217, ensuring that the lubrication effect is just right, and greatly improving the efficiency of lubricant use.
