[0021] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] according to Figure 1 、 2 As shown in Figures 3 and 4, a reel fixing device is proposed in this embodiment, comprising a mounting frame for placing a reel body 1, with fixed shafts 2 provided at both ends of the reel body 1, the mounting frame comprising two side brackets 5, at least two support ribs 6 provided between the two side brackets 5, and both ends of the support ribs 6 being fixedly connected to the side brackets 5;

[0023] A U-shaped bracket 9 for supporting the fixed shaft 2 is provided above the support rib 6, and a lifting bracket is provided between the U-shaped bracket 9 and the support rib 6, and the lifting bracket is detachably connected to the support rib 6;

[0024] There are two U-shaped supports 9. The cylinder body 1 to be assembled is placed between the two side supports 5. The lifting support props up the U-shaped support 9. The U-shaped support 9 supports the fixed shaft 2 from both ends of the cylinder body 1.

[0025] A transmission disk 11 is provided at the upper end of the side bracket 5, and the transmission disk 11 is rotatably connected to the side bracket 5. At least two latch rods 12 are provided through the transmission disk 11, and the latch rods 12 are slidably connected to the transmission disk 11. A positioning disk group is provided at one end of the fixed shaft 2 close to the transmission disk 11, and an adjustment mechanism is provided at the end of the transmission disk 11 away from the fixed shaft 2 for pushing the latch rod 12 and plugging the latch rod 12 into the positioning disk group.

[0026] When the axis of the cylinder body 1 coincides with the axis of the transmission disk 11, the latch rod 12 on the transmission disk 11 is inserted into the positioning disk group fixed on the fixed shaft 2 through the adjustment mechanism, and the latch rod 12 will cooperate with the positioning disk group to connect the transmission disk 11 and the two ends of the cylinder body 1 together. At this time, it is only necessary to control the rotation of the transmission disk 11, and the cylinder body 1 between the two side brackets 5 will also rotate accordingly. The cylinder body 1 is easy to disassemble, and the plug-in latch rod 12 can be moved horizontally to assemble cylinder bodies 1 of different lengths, and has a wide range of applicability.

[0027] About the lifting bracket:

[0028] The lifting bracket includes a movable seat 8, which is slidably connected to the upper end of the support rib 6. A bolt connector is provided at the connection between the movable seat 8 and the support rib 6 for fixing the movable seat 8. Electric push rods 10 are provided at both ends of the movable seat 8. The mounting end of the electric push rod 10 is fixedly connected to the movable seat 8, and the output end of the electric push rod 10 is fixedly connected to the U-shaped support 9.

[0029] The movable seat 8 is fixed to the upper end of the support rib 6 via a bolt connector. The support rib 6 supports the movable seat 8. The height of the U-shaped bracket 9 is controlled by the electric push rod 10. When installing the cylinder body 1, the cylinder body 1 is placed between the two side brackets 5. The fixed shafts 2 at both ends of the cylinder body 1 are mounted on the two U-shaped brackets 9. The electric push rod 10 pushes the U-shaped bracket 9, which raises the cylinder body 1 upward until the positioning disk assembly and the transmission disk 11 are at the same height and the axes of the cylinder body 1, positioning disk assembly, and transmission disk 11 coincide with each other. After the cylinder body 1 is assembled, the U-shaped bracket 9 is lowered and stored.

[0030] It is worth further explaining that a groove 16 is defined at the lower end of the movable seat 8, into which the upper end of the support rib 6 engages and is slidably connected. The bolt connector includes a plurality of positioning holes 7 defined at the upper end of the support rib 6, which are threadedly connected to positioning bolts 17 mounted on the upper end of the movable seat 8. When the positioning bolts 17 are released from the positioning holes 7, the movable seat 8 can slide horizontally along the support rib 6 or be completely removed from the support rib 6. The groove 16 cooperates with the support rib 6 to guide the movable seat 8. By changing the fixed position of the positioning bolts 17 and the positioning holes 7, the position of the movable seat 8 and the U-shaped support 9 can be adjusted, thereby meeting the assembly requirements of cylinder bodies 1 of different lengths, providing high flexibility.

[0031] The positioning plate group includes a limit plate 3, which is fixedly connected to the end of the fixed shaft 2 away from the cylinder body 1. The axis of the limit plate 3 coincides with the axis of the cylinder body 1 and the fixed shaft 2. A limit hole 4 is provided on the limit plate 3, and the limit hole 4 is plugged into the latch rod 12.

[0032] The limit plate 3 is fixed to the cylinder body 1 via a fixed shaft 2 and can rotate with the cylinder body 1. When assembling the cylinder body 1, the two latch rods 12 on the transmission plate 11 are pushed into the limit holes 4 provided on the limit plate 3. When the transmission plate 11 rotates, the transmission plate 11 will rotate with the limit plate 3 via the latch rods 12, and the cylinder body 1 will also rotate. The rotation of the transmission plate 11 can be controlled by a belt drive, chain drive, or gear drive, which will not be explained in detail here.

[0033] In a preferred embodiment, the diameter of the limiting plate 3 is larger than the diameter of the fixed shaft 2. The advantage of this design is that when the U-shaped brackets 9 support the fixed shaft 2 from both ends of the cylinder body 1, the U-shaped brackets 9 will be stuck between the cylinder body 1 and the limiting plate 3, so that there is no risk of the cylinder body 1 falling off the U-shaped brackets 9, and safety is improved.

[0034] About the regulatory body:

[0035] The adjusting mechanism includes an adjusting block 13 and an adjusting screw 14. The adjusting screw 14 is rotatably connected to the end of the transmission plate 11 away from the U-shaped support 9. The adjusting block 13 is sleeved on the outside of the adjusting screw 14 and is threadedly connected to the adjusting screw 14. The adjusting block 13 is fixedly connected to the end of the latch rod 12 away from the U-shaped support 9.

[0036] The specific adjustment steps are as follows:

[0037] By rotating the adjusting screw 14, the adjusting screw 14 will cooperate with the adjusting block 13, and the adjusting block 13 will move along the rod of the adjusting screw 14. When the adjusting block 13 approaches the transmission disk 11, the latch rod 12 will also approach the limit disk 3 under the push of the adjusting block 13. When the adjusting block 13 moves away from the transmission disk 11, the latch rod 12 fixed to the adjusting block 13 will be pulled out from the limit hole 4 on the limit disk 3.

[0038] In a preferred embodiment, a rubber pad 15 is provided on the side of the adjustment block 13 facing the transmission disc 11. The rubber pad 15 is positioned outside the latch rod 12 and is fixedly connected to the adjustment block 13. By rotating the adjustment screw 14, the adjustment block 13 approaches the transmission disc 11. When the adjustment block 13 is about to contact the transmission disc 11, the rubber pad 15 on the adjustment block 13 will contact the transmission disc 11 first, thus protecting both the transmission disc 11 and the adjustment block 13.

[0039] The working principle of this utility model:

[0040] There are two U-shaped supports 9. The cylinder body 1 to be assembled is placed between the two side supports 5. The lifting support props up the U-shaped support 9, and the U-shaped support 9 supports the fixed shaft 2 from both ends of the cylinder body 1. The axes of the cylinder body 1, the positioning disk assembly, and the transmission disk 11 coincide with each other. After the cylinder body 1 is assembled, the U-shaped support 9 falls down and is put away. When the axis of the cylinder body 1 coincides with the axis of the transmission disk 11, the adjusting screw 14 is rotated, and the adjusting screw 14 cooperates with the adjusting block 13. The adjusting block 13 moves along the rod of the adjusting screw 14. When the adjusting block 13 approaches the direction of the transmission disk 11, the latch rod 12, pushed by the adjusting block 13, will also approach the direction of the limit disk 3. The two latch rods 12 on the transmission disk 11 are pushed into the limit holes 4 opened on the limit disk 3. When the transmission disk 11 rotates, the transmission disk 11 will rotate with the limit disk 3 through the latch rod 12, and the cylinder body 1 will also rotate accordingly.
