DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] All features disclosed in this specification, or all steps in any method or process disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0017] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated otherwise, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated otherwise, each feature is only an example of a series of equivalent or similar features.

[0018] According to Figures 1-4As shown in the figure, a push-type safety chuck includes an external shaft body 1 and a chuck 2. An internal shaft body 3 is arranged inside the external shaft body 1, and an adjusting screw rod 11 is further arranged at one end of the external shaft body 1. At both ends of the internal shaft body 3, a transmission block 31 and a screw rod sleeve 32 are respectively fixed. The transmission block 31 is located outside the external shaft body 1 and is fixed to the surface of the internal shaft body 3. The screw rod sleeve 32 is located at one end close to the adjusting screw rod 11 and is fixed to the inner wall of the internal shaft body 3. The screw rod sleeve 32 is in fit connection with the adjusting screw rod 11 for controlling the movement of the internal shaft body 3 and the transmission shaft 4. A transmission shaft 4 is arranged in the internal shaft body 3 through a bearing. At one end of the transmission shaft 4 close to the screw rod sleeve 32, a cavity 41 for accommodating the adjusting screw rod 11 is arranged. At the end of the transmission shaft 4 where the transmission block 31 is arranged, a connecting section 42 is extended for arranging the chuck 2. A through hole 21 is provided at the center of the chuck 2, and a support torque block 22 and a fixing block 23 are fixedly arranged in the through hole 21. An air shaft 5 is arranged between the support torque block 22 and the fixing block 23. The connecting section 42 is embedded in the gap of the through hole 21, and the chuck 2 is arranged on the connecting section 42.

[0019] A fixing cover 12 is further arranged on the external shaft body 1. The fixing cover 12 is fixedly connected with one end of the external shaft body 1 through a bolt. The adjusting screw rod 11 is connected with the fixing cover 12 through a bearing. An adjusting grip 6 is further arranged on the adjusting screw rod 11, which is convenient for rotating the adjusting screw rod 11 to adjust the position of the internal shaft body 3.

[0020] Long oval longitudinal fixing grooves 44 are arranged on both sides of the connecting section 42, and a transverse fixing groove 45 is arranged at the bottom of the connecting section 42. An anti-rotation pin 24 that cooperates with the longitudinal fixing groove 44 is arranged on the chuck 2 for preventing the chuck 2 from shaking during the winding process and preventing the chuck 2 from rotating independently. A safety pin 25 that cooperates with the transverse fixing groove 45 is also arranged. The transverse fixing groove 45 is composed of two semi-circular grooves arranged on the chuck 2 and the connecting section 42 to form a circular hole. The safety pin 25 is in fit with the circular hole to prevent the chuck 2 from falling off.

[0021] On one side of the chuck 2 close to the transmission block 31, a fixing plate 26 is arranged around the through hole 21. A fixing groove 27 is arranged at the position of the fixing plate 26 corresponding to the transmission block 31. A transmission wheel 33 is further arranged on the transmission block 31. The fixing groove 27 is arranged in cooperation with the transmission wheel 33 for driving the chuck 2 to rotate together with the shaft body.

[0022] Connection pieces 51 for installation are arranged at both ends of the air shaft 5, and the connection pieces 51 are arranged in a square structure.

[0023] In the practical process, first, the connecting piece 51 is set between the two chucks 2 on both sides, then the connecting piece 51 is set in one of the chucks 2. Next, by rotating the adjusting grip 6, the inner shaft body 3 and the transmission shaft 4 are pushed forward, so that the chucks on both sides of the chuck 2 can fix the air shaft 5. Finally, check whether the anti-rotation pin 24 and the safety pin 25 are accurately installed to complete the entire setting process.

[0024] This design is ingenious. Through the cooperation of the chuck 2 and the adjusting screw rod 11, users can quickly disassemble and assemble the air shaft 5, which not only simplifies the operation process but also significantly improves production efficiency, especially in the production environment where the material roll needs to be frequently replaced; the setting of the anti-rotation pin 24 and the safety pin 25 ensures the stability of the chuck 2 on the connecting section 42, reducing the risk of chuck displacement caused by vibration or accidental impact; the setting of the fixing groove 27 and the transmission wheel 33 can effectively drive the rotation of the chuck 2. This design ensures the smooth transmission of torque and also helps to reduce energy loss and improve transmission efficiency.

[0025] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
