[0012] Compared with the prior art, the present utility model provides an improved waterproof linear module, which has the following
[0013] Beneficial effects:
[0014] 1. In this improved waterproof linear module, when the gear disc rotates, it will drive the arc-shaped groove to rotate together. When the arc-shaped groove rotates, it will contact the sliding rod, but the moving block at the end of the sliding rod away from the arc-shaped groove is located inside the sliding groove, so that the sliding groove limits the moving block. Thus, when the sliding rod is pushed by the arc-shaped groove and slides, the moving block slides inside the sliding groove, and when the moving block slides, it will push the guiding rod to move the positioning block towards the direction of the lead screw. Subsequently, the positioning block will drive the stabilizing roller to fit with the surface of the lead screw. Through the tail plates on both sides of the guide rail and the six groups of positioning blocks arranged in a circumferential array, the axes at both ends of the lead screw can be kept consistent, so that the axes at the front and rear ends of the lead screw are kept consistent when the lead screw rotates, thereby reducing the increased wear caused by the inclination of the axis of the lead screw.
[0015] 2. In the improved waterproof linear module, when the bolt rotates, it will gradually move in the direction of the first rotating shaft. At the same time, when the bolt rotates, it will not only drive the bolt to rotate through the toothed shaft, but also make the toothed shaft gradually insert into the first rotating shaft. When the bolt rotates into the inner side of the U-shaped frame, it has a certain self-locking function, enabling the stabilizing roller in the positioning block to stably maintain the positioning of the lead screw. Moreover, the O-ring seal and the top cover waterproof cover can play a certain waterproof role for the linear module, preventing liquid from seeping in and affecting the use of the linear module.

[0026] AsFigures 1-9 As shown in Figures 1-9 , the present utility model provides a technical solution: an improved waterproof linear module, which includes a guide rail 1, a motor support base 4, a support base protective cover 5, a motor 6, a top cover waterproof cover 7 and a tail plate waterproof cover 8. A rubber waterproof cover 9 and an O-ring seal 10 are arranged between the top cover waterproof cover 7 and the guide rail 1. Inside the guide rail 1, there are a driven part 3 for linear motion and a control part 2 for stable linear motion.
[0027] The control part 2 includes a tail plate 21, a U-shaped frame 22, bolts 23, a toothed shaft 24, a first rotating shaft 25, a first bevel gear 26, a second rotating shaft 27, a second bevel gear 28, a small gear 29, a rotating groove 210, a gear disc 211, an arc-shaped groove 212, a sliding groove 213, a moving block 214, a sliding rod 215, a guiding rod 216, a positioning block 217, a stabilizing roller 218, and a spring 219.
[0028] One side of the tail plate 21 close to the guide rail 1 is fixedly connected to the surface of the guide rail 1. A U-shaped frame 22 is fixedly connected to the bottom surface of the tail plate 21. A bolt 23 is inserted through and threadedly connected to the inside of the U-shaped frame 22. When the bolt 23 rotates, it will gradually move towards the direction of the first rotating shaft 25. At the same time, when the bolt 23 rotates, it will not only drive the bolt 23 to rotate through the gear shaft 24, but also cause the gear shaft 24 to gradually insert into the first rotating shaft 25. When the bolt 23 is inserted into the inside of the U-shaped frame 22, it has a certain self-locking function. The top surface of the bolt 23 is fixedly connected to the gear shaft 24. The gear shaft 24 penetrates through the first rotating shaft 25. Insert the lead screw 33 into the guide rail 1 and make the lead screw 33 pass through the gear disk 211, and then turn the bolt 23. When the bolt 23 rotates, it will drive the first rotating shaft 25 to rotate through the gear shaft 24. The first rotating shaft 25 penetrates through the tail plate 21 and is rotatably connected. One end of the first rotating shaft 25 located inside the tail plate 21 penetrates through and is fixedly connected to a first bevel gear 26. A second rotating shaft 27 is inserted through and rotatably connected to the inside of the tail plate 21. The second rotating shaft 27 penetrates through and is fixedly connected to a second bevel gear 28 and a small gear 29. The first bevel gear 26 meshes with the second bevel gear 28. A rotating groove 210 is formed inside the enclosing plate 21. A gear disk 211 is inserted through and rotatably connected to the inside of the rotating groove 210. The gear disk 211 meshes with the small gear 29. An arc-shaped groove 212 is formed on the surface of the gear disk 211. When the bolt 23 rotates, it will drive the first rotating shaft 25 to rotate through the gear shaft 24. The first rotating shaft 25 will drive the second rotating shaft 27 to rotate through the first bevel gear 26 and the second bevel gear 28. The second rotating shaft 27 will drive the gear disk 211 to rotate through the small gear 29. When the gear disk 211 rotates, it will drive the arc-shaped groove 212 to rotate together. A sliding groove 213 is formed inside the rotating groove 210. A moving block 214 is inserted through and slidably connected to the inside of the sliding groove 213. When the arc-shaped groove 212 rotates, it will abut against the sliding rod 215. However, the moving block 214 at one end of the sliding rod 215 away from the arc-shaped groove 212 is located inside the sliding groove 213, so that the sliding groove 213 limits the moving block 214. A sliding rod 215 is fixedly connected to the surface of the moving block 214. The sliding rod 215 penetrates through the arc-shaped groove 212 and is slidably connected. A guiding rod 216 is fixedly connected to the surface of the moving block 214. One end of the guiding rod 216 away from the moving block 214 is fixedly connected to a positioning block 217. A stabilizing roller 218 is inserted through and rotatably connected to the surface of the positioning block 217. The moving block 214 slides inside the sliding groove 213. When the moving block 214 slides, it will push the guiding rod 216 to move the positioning block 217 towards the direction of the lead screw 33. Subsequently, the positioning block 217 will drive the stabilizing roller 218 to fit against the surface of the lead screw 33. A spring 219 is fixedly connected between the moving block 214 and the inside of the sliding groove 213.The driven part 3 includes a synchronous pulley 31. The synchronous pulley 31 is penetrated by the output shaft of the motor 6 and fixedly connected. A lead screw 33 is penetrated and rotatably connected to the inner side of the guide rail 1. The lead screw 33 is penetrated and threadedly connected with a slider 35. A bearing 34 is penetrated by the lead screw 33. Both the lead screw 33 and the output shaft of the motor 6 are penetrated and fixedly connected with synchronous pulleys 31. And the synchronous pulley 31 penetrated by the lead screw 33 and the synchronous pulley 31 penetrated by the output shaft of the motor 6 are drivingly connected by a synchronous belt 32.
[0029] Based on the above embodiment, when installing or replacing the main transmission device, the lead screw 33, in the driven part 3, insert the lead screw 33 into the guide rail 1, and make the lead screw 33 pass through the gear disk 211. Then, turn the bolt 23. When the bolt 23 rotates, it will drive the rotating shaft one 25 to rotate through the gear shaft 24. The rotating shaft one 25 will drive the rotating shaft two 27 to rotate through the bevel gear one 26 and the bevel gear two 28. The rotating shaft two 27 will drive the gear disk 211 to rotate through the pinion 29. When the gear disk 211 rotates, it will drive the arc-shaped groove 212 to rotate together. When the arc-shaped groove 212 rotates, it will abut against the slide bar 215. However, the moving block 214 at one end of the slide bar 215 away from the arc-shaped groove 212 is located in the chute 213, so that the chute 213 limits the moving block 214. Therefore, when the slide bar 215 is abutted by the arc-shaped groove 212 and slides, the moving block 214 slides in the chute 213. When the moving block 214 slides, it will push the guide bar 216 to make the positioning block 217 move towards the lead screw 33. Subsequently, the positioning block 217 will drive the stabilizing roller 218 to fit against the surface of the lead screw 33. Through the end plates 21 on both sides of the guide rail 1 and the six groups of positioning blocks 217 arranged in a circumferential array, the axes at both ends of the lead screw 33 can be kept consistent, so that the axes at the front and rear ends of the lead screw 33 are kept consistent when the lead screw 33 rotates, thereby reducing the increased wear caused by the inclination of the axis of the lead screw 33. And when the bolt 23 rotates, it will gradually move towards the direction of the rotating shaft one 25. At the same time, when the bolt 23 rotates, it will not only drive the bolt 23 to rotate through the gear shaft 24, but also make the gear shaft 24 gradually insert into the rotating shaft one 25. When the bolt 23 turns into the inner side of the U-shaped frame 22, it has a certain self-locking function, so that the stabilizing roller 218 in the positioning block 217 can stably maintain the positioning of the lead screw 33.
[0030] When the linear module is in use, first start the motor 6. The output shaft of the motor 6 will drive the synchronous pulley 31 to rotate. The synchronous pulley 31 penetrated by the motor 6 drives the synchronous pulley 31 penetrated by the lead screw 33 to rotate through the synchronous belt 32, so that the lead screw 33 rotates. The lead screw 33 will drive the threadedly connected slider 35 to move in the guide rail 1.
[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and idea of the present utility model fall within the protection scope of the present utility model.
