Detailed Description of the Embodiments

[0022] The following will further describe the present utility model in conjunction with the appended Figures 1-4 drawings.

[0023] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not refer only to the direct connection of components, but refer to the composition of a more optimal connection structure by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be interactively combined on the premise of not conflicting with each other.

[0024] Referring to Figure 1 and Figure 2 , the present utility model provides a shaft head fixing structure for reducing the possibility that the winding shaft 4 will jump during installation and affect the winding shaft 4. It includes a support block 1, a clamping block 2 and a bolt-type clamp 3. Among them, the support block 1 is used to support the winding shaft 4. During installation, the support block 1 can be fixedly arranged on the wall panel through fasteners such as screws; the clamping block 2 is rotatably connected to the support block 1. An installation space 11 is formed between the support block 1 and the clamping block 2. The end of the winding shaft 4 is rotatably connected to the installation space 11. The clamping block 2 is used to press the winding shaft 4 and limit the winding shaft 4 in the installation space 11; the bolt-type clamp 3 is used to clamp and fix the support block 1 and the clamping block 2 to improve the bearing capacity of the entire structure, so as to ensure that the winding shaft 4 can rotate stably in the installation space 11.

[0025] In this embodiment, only the support block 1 and the clamping block 2 are arranged at one end of the winding shaft 4 for fixing, that is, one end of the winding shaft 4 is fixed by the shaft head fixing structure of the present utility model, and the other end is fixed by a conventional chuck structure (not shown in the figure). The chuck structure refers to the prior art and will not be elaborated here. The shaft head fixing structure of the present utility model is arranged on one side of the winding shaft 4. During installation, only the chuck structure on the other side of the winding shaft 4 needs to be rotated in place to realize taking the roll. Compared with the situation where chuck structures are arranged on both sides, the requirement for the synchronization of the two chucks is effectively reduced, thereby reducing the waiting time for taking the roll and improving the installation efficiency. In addition, since one side of the winding shaft 4 is locked by the shaft head fixing structure and the other side uses the chuck structure, the locking of the bolt-type clamp 3 is reliable. Compared with the installation of the chuck structure, the winding roll can be effectively prevented from moving during the winding rotation process, ensuring the winding quality.

[0026] Furthermore, the clamping block 2 is provided with a semicircular upper opening, and the support block 1 is provided with a lower opening. The upper opening and the lower opening enclose a circular installation space 11. A bearing 41 is connected to the end of the winding shaft 4. The shape and size of the installation space 11 are adapted to the bearing 41. The winding shaft 4 rotates in the installation space 11 through the bearing 41.

[0027] Furthermore, a limit stopper 12 is fixedly connected to the side of the support block 1 facing the winding shaft 4, and the bearing 41 abuts against the limit stopper 12. The limit stopper 12 limits the bearing 41 to ensure that the limit stopper 12 does not leave the installation space 11 during use.

[0028] Reference Figure 3 and Figure 4 The clamping block 2 is rotatably connected to the support block 1. Specifically, a rotating shaft 13 is provided on one side of the support block 1. A mounting hole is provided on the support block 1. The rotating shaft 13 is passed through the mounting hole and the end of the rotating shaft 13 passes through the mounting hole. A shaft retaining ring 131 is fixedly connected to the end of the rotating shaft 13. The shaft retaining ring 131 limits and fixes the rotating shaft 13. A rotating through hole 21 is correspondingly provided on one side of the clamping block 2. The rotating shaft 13 is rotatably connected to the rotating through hole 21. The clamping block 2 is rotatably connected to the support block 1, which is convenient for opening and closing, and is convenient for the winding shaft 4 (in Figure 1 The installation is marked in the middle) and is locked by a bolt-type clamp 3. The locking strength is high. When the equipment is changing rolls, the connection strength between the clamping block 2 and the supporting block 1 can be ensured when the winding shaft 4 is turned over.

[0029] Furthermore, a fixing pin 14 is provided on the support block 1, a fixing through hole 22 is provided on the side of the clamping block 2 away from the rotating through hole 21, and a connecting through hole 15 is provided on the support block 1. The fixing pin 14 is detachably provided in the connecting through hole 15. When the clamping block 2 is rotated into place, the connecting through hole 15 is aligned with the fixing through hole 22, and the fixing pin 14 is inserted at this time. The ends of the fixing pin 14 are sequentially passed through the connecting through hole 15 and the fixing through hole 22. The fixing pin 14 is provided to further fix the support block 1 and the clamping block 2, and further reduce the possibility of the clamping block 2 and the support block 1 moving during use.

[0030] Furthermore, the support block 1 is detachably provided with an elastic pin 16. Specifically, a limiting hole 17 is provided on the support block 1, and the limiting hole 17 is connected to the connecting through hole 15. A limiting groove 141 is provided on the outer peripheral side of the fixing pin 14. When the limiting pin is inserted into the fixing through hole 22 to limit and fix the support block 1 and the clamping block 2, the limiting groove 141 is aligned with the limiting hole 17. At this time, the elastic pin 16 is inserted into the limiting hole 17, and the end of the elastic pin 16 is inserted into the limiting groove 141 to limit and fix the fixing pin 14. The elastic pin 16 is provided to limit and fix the fixing pin 14 to ensure the connection reliability of the fixing pin 14, and the structure is simple and easy to install and disassemble.

[0031] Reference Figure 4 The bolt-type clamp 3 includes a fixed buckle groove 31 and a manual buckle. The fixed buckle groove 31 is fixedly arranged on the clamping block 2 and is located on the side of the clamping block 2 away from the rotating through hole 21. The manual buckle is fixedly arranged on the support block 1. The manual buckle includes a support seat 32, an operating handle 33 and a U-shaped bolt 34. The support seat 32 is fixedly arranged on the support block 1, the operating handle 33 is rotatably arranged on the support seat 32, and the U-shaped bolt 34 is fixed on the operating handle 33. Since the winding device will perform operations such as changing rolls during the winding process, the rotation of the turntable during the changing of rolls will cause the device to flip over, and after flipping, the stressed parts will change from the support block 1 to the clamping block 2. The bolt-type clamp 3 is provided for locking, which can effectively ensure the connection strength between the support block 1 and the clamping block 2, and can also achieve effective locking after flipping, which effectively improves the bearing capacity of the entire structure.

[0032] When in use, the operator lifts or buckles the operating handle 33 of the bolt-type clamp 3 , thereby driving the U-shaped bolt 34 to move, so that the U-shaped bolt 34 buckles into or out of the fixed buckle groove 31 .

[0033] The implementation of the utility model is as follows:

[0034] Before use, first fix the support block 1 on the wall panel by screws, then place the shaft head of the winding roller on the support block 1, rotate the clamping block 2, so that the clamping block 2 rotates around the rotating shaft 13 to press the bearing 41 at the end of the winding shaft 4, and when the clamping block 2 is rotated into place (that is, the clamping block 2 completely presses the bearing 41 at the end of the winding shaft 4), turn the operating handle 33 so that the U-shaped bolt 34 is buckled into the fixed buckle groove 31 to lock and fix the clamping block 2. Then install the fixed pin 14 to limit the movement of the clamping block 2. When the fixed pin 14 is installed in place, pull the elastic pin 16 so that the elastic pin 16 is stuck in the limit groove 141 of the fixed pin 14, further limiting the axial movement of the fixed pin 14.
