[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 5As shown, a combined tubular mold fixing fixture includes a mounting block 1, the right part of the mounting block 1 is fixedly connected to a shaft 11, the outer wall of the shaft 11 is rotatably connected to a splint 12, the outer wall of the shaft 11 is rotatably connected to a splint 2 13, the outer walls of splint 12 and splint 2 13 are both fixedly connected to a clamping mechanism 2, the right end of splint 12 is rotatably connected to a limiting mechanism 3, the clamping mechanism 2 includes a fixed frame 21, the outer wall of the fixed frame 21 is fixedly connected to the outer wall of splint 12, the limiting mechanism 3 includes a rotating plate 31, the top of the rotating plate 31 is rotatably connected to the right end of splint 12.

[0025] The tubular mold is placed on the inner wall of the second splint 13 in sequence, and then the first splint 12 and the second splint 13 are limited by the limiting mechanism 3 so that the first splint 12 and the second splint 13 are closed, and then the tubular mold is clamped and fixed by the clamping mechanism 2.

[0026] like Figure 2 、 Figure 3 As shown, the inner wall of the fixed frame 21 is rotatably connected to the rotating rod 22, the outer wall of the rotating rod 22 is fixedly connected to the worm 23, the bottom of the worm 23 is engaged with a worm gear plate 24, the outer wall of the worm gear plate 24 is slidingly connected to the inner wall of the splint 12, the outer shape of the worm gear plate 24 is arc-shaped, the front and rear ends of the worm gear plate 24 are fixedly connected to the limit plate 25, the outer wall of the limit plate 25 is slidingly connected to the inner wall of the splint 12, and the outer shape of the limit plate 25 is arc-shaped.

[0027] By rotating the rotating rod 22, the worm 23 is driven to rotate, so that the outer wall of the worm 23 is meshed with the outer wall of the worm gear plate 24, so that the worm gear plate 24 drives the limiting plate 25 to slide on the inner wall of the clamping plate 12. The limiting plate 25 restricts the worm gear plate 24, so that the worm gear plate 24 cannot continue to rotate after it rotates to a certain position, and at the same time, the worm gear plate 24 always remains in meshing state with the worm 23.

[0028] like Figure 2-Figure 4 As shown, the inner wall of the worm gear plate 24 is fixedly connected with a protrusion 26, the inner wall of the worm gear plate 24 is overlapped with a pulley 27, the outer wall of the pulley 27 is rotatably connected with a mounting plate 271, the bottom end of the mounting plate 271 is fixedly connected with a connecting rod 272 in a linear array, the outer wall of the connecting rod 272 is slidably connected to the inner wall of the splint 12, and the bottom end of the connecting rod 272 is fixedly connected with a clamping plate 28.

[0029] When the worm gear plate 24 rotates, it drives the protrusion 26 to rotate synchronously, so that the outer wall of the pulley 27 contacts the outer wall of the protrusion 26. As the pulley 27 gradually contacts the highest point of the protrusion 26, the pulley 27 drives the mounting plate 271 and the connecting rod 272 to move synchronously, so that the connecting rod 272 slides on the inner wall of the clamping plate 12, driving the clamping plate 28 to move synchronously.

[0030] like Figure 2 、 Figure 3 As shown, a spring 29 is fixedly connected to the outer wall of the clamping plate 28, and the top of the spring 29 is fixedly connected to the inner wall of the clamping plate 12. The outer shape of the spring 29 is arc-shaped.

[0031] When the clamping plate 28 moves, it drives the spring 1 29 to stretch, so that the outer wall of the clamping plate 28 is in close contact with the outer wall of the tubular mold, thereby clamping the tubular mold and achieving the effect of clamping tubular molds of different sizes.

[0032] like Figure 2 、 Figure 5 As shown, an insert block 32 is fixedly connected to the bottom of the rotating plate 31 , and the outer wall of the insert block 32 is plugged into the inner wall of the right part of the second clamping plate 13 .

[0033] By rotating the rotating plate 31 , the rotating plate 31 drives the inserting block 32 to rotate synchronously, so that the outer wall of the inserting block 32 is inserted into the inner wall of the second clamping plate 13 .

[0034] like Figure 2 、 Figure 5 As shown, the inner wall of the plug block 32 is connected with an insert rod 33, and the part where the insert rod 33 and the plug block 32 are connected is trapezoidal. The outer wall of the insert rod 33 is slidingly connected to the inner wall of the splint 13, and the front end of the insert rod 33 is fixedly connected to the connecting plate 34, and the rear end of the connecting plate 34 is fixedly connected to the spring 2 35, and the rear end of the spring 2 35 is fixedly connected to the front end of the splint 13, and the inner wall of the spring 2 35 is movably sleeved with the outer wall of the insert rod 33.

[0035] When the outer wall of the plug block 32 is inserted into the inner wall of the second splint 13, the outer wall of the plug block 32 contacts the outer wall of the insertion rod 33. Because the rear part of the insertion rod 33 is trapezoidal in shape and inclined to the right, when the outer wall of the plug block 32 contacts the insertion rod 33, it contacts the inclined surface of the insertion rod 33, which causes the insertion rod 33 to slide on the inner wall of the second splint 13, driving the connecting plate 34 to move synchronously, causing the spring 2 35 to stretch. When the outer wall of the plug block 32 is fully inserted into the inner wall of the second splint 13, the insertion rod 33 is inserted into the inner wall of the plug block 32 under the action of the elastic force of the second spring 35, thereby limiting the plug block 32 and preventing the rotating plate 31 from rotating, thereby restricting the first splint 12 and the second splint 13, thereby achieving a limiting effect.

[0036] The working principle of the present invention is as follows: when in use, the tubular mold to be clamped is placed on the inner wall of the second clamping plate 13, and then the first clamping plate 12 is rotated to close the first clamping plate 12 and the second clamping plate 13. After closing, the rotating plate 31 is rotated to make the rotating plate 31 drive the plug 32 to rotate synchronously, so that the outer wall of the plug 32 is plugged into the inner wall of the second clamping plate 13. During the plugging process, the outer wall of the plug 32 contacts the outer wall of the plug rod 33. Because the outer shape of the rear part of the plug rod 33 is trapezoidal and inclined to the right, when the outer wall of the plug 32 is in contact with the inner wall of the second clamping plate 13, the outer wall of the plug 32 is in contact with the outer wall of the plug rod 33. When the plug rod 33 contacts, it contacts the inclined surface of the plug rod 33, which causes the plug rod 33 to slide on the inner wall of the second splint 13, driving the connecting plate 34 to move synchronously, causing the spring 2 35 to stretch. When the outer wall of the plug block 32 is completely inserted into the inner wall of the second splint 13, the plug rod 33 is inserted into the inner wall of the plug block 32 under the action of the elastic force of the second spring 35, thereby limiting the plug block 32 and preventing the rotating plate 31 from rotating, thereby limiting the splint 12 and the second splint 13, playing a limiting effect. The size of each tubular mold is determined by rotating the rotating rod 22, which drives the worm 23 to rotate, so that the outer wall of the worm 23 is engaged with the outer wall of the worm gear plate 24, so that the worm gear plate 24 drives the limiting plate 25 to slide on the inner wall of the splint 12, and the limiting plate 25 limits the worm gear plate 24 so that the worm gear plate 24 cannot continue to rotate after it is rotated to a certain position, and at the same time, the worm gear plate 24 is always kept in meshing with the worm 23, and the worm gear plate 24 drives the protrusion 26 to rotate synchronously, so that the outer wall of the pulley 27 is engaged with the protrusion 26, as the pulley 27 gradually contacts the highest point of the protrusion 26, the pulley 27 drives the mounting plate 271 and the connecting rod 272 to move synchronously, so that the connecting rod 272 slides on the inner wall of the clamping plate 12, drives the clamping plate 28 to move synchronously, and the clamping plate 28 drives the spring 1 29 to stretch, so that the outer wall of the clamping plate 28 is in close contact with the outer wall of the tubular mold, thereby clamping the tubular mold, which has the effect of clamping tubular molds of different sizes, thereby greatly improving the user experience.
