[0036] See also Figures 1 to 3 , the utility model embodiment discloses a locking structure, such as Figure 2 As shown, it includes a core rod 1, a piston cylinder 2 and a first locking member 5, wherein the piston cylinder 2 is located at one end of the first locking member 5, the core rod 1 is arranged in the first locking member 5 and one section of it extends into the piston cylinder 2, and the end face of the core rod 1 does not contact the piston cylinder 2 to avoid friction caused by contact; the end of the core rod 1 close to the piston cylinder 2 is also sleeved with a force-bearing structure 3, and the piston cylinder 2 is also provided with a first step 201 for limiting the force-bearing structure 3, one end of the force-bearing structure 3 is in contact with the first step 201, and the piston cylinder 2 applies a thrust to the force-bearing structure 3 by pushing the first step 201; when the piston cylinder 2 is driven to move toward the first locking member 5, the piston cylinder 2 pushes the force-bearing structure 3 to move toward the first locking member 5 so that the core rod 1 extends out of the first locking member 5 to open the locking structure. Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 The enlarged part at A in the middle shows that the locking structure of the utility model is applied to the rewinding machine 100. Specifically, the rewinding machine 100 is used to wind the processed pipes, and the pipes are placed on the reel 400 for winding. After the winding work is completed, the reel is unloaded. The unloading process requires the small plate 500 of the rewinding machine 100 to be separated from the reel 400. The locking structure is used to connect / separate the small plate 500 and the reel 400. In addition, the locking structure of the utility model transfers the thrust of the piston cylinder 2 to the core rod 1 to the force-bearing structure 3 to avoid friction between the end of the core rod 1 and the inner wall of the piston cylinder 2.
[0037] Specifically, the piston cylinder 2 pushes oil through the oil pump to pressurize the cylinder, and the oil pressure pushes the piston cylinder 2 to move in the horizontal direction. Further, the first step 201 in the piston cylinder 2 abuts against the force-bearing structure 3, and the force-bearing structure 3 pushes the core rod 1 to move in the horizontal direction.
[0038] In this embodiment, the force-bearing structure 3 includes but is not limited to a bearing, and the piston cylinder 2 pushes the force-bearing structure 3 to push the core rod 1 to move, so as to prevent stress concentration at the end of the core rod 1; in addition, in the prior art, the locking structure is located on one side of the small disk 500 of the rewinding machine 100, and the large disk 300 and the reel 400 of the rewinding machine 100 are connected with the transmission mechanism 200, and the transmission mechanism 200 drives the large disk 300 and the reel 400 to rotate. When the locking structure is locked, the core rod 1 is driven to rotate. However, in the prior art, the piston cylinder 2 abuts against the end surface of the core rod 1, so that When the core rod 1 is driven to rotate by the transmission mechanism 200, the end face rubs against the inner wall of the piston cylinder 2, which is easy to wear; the end face of the core rod 1 of the locking structure of the utility model does not contact the inner wall of the piston cylinder 2, thereby avoiding wear of the core rod during rotation, and at the same time, a force-bearing structure 3 is arranged on the outer side of one end of the core rod 1 close to the piston cylinder 2; wherein the force-bearing structure 3 is preferably a bearing, and when the core rod 1 rotates, the bearing is supported between the core rod 1 and the piston cylinder 2 for easy rotation, which not only avoids the problem of stress concentration at the end of the core rod 1, but also avoids the friction between the end face and the piston cylinder 2 when the core rod 1 rotates.
[0039] like Figure 3 As shown, in this embodiment, a limiting structure 7 is also included. The limiting structure 7 is sleeved on one end of the core rod 1 close to the piston cylinder 2. The inner side of the force-bearing structure 3 is engaged with the limiting structure 7 so that when the piston cylinder 2 presses against the force-bearing structure 3, no displacement occurs, making it more secure.
[0040] In this embodiment, a fixing member 4 is further included for fixing the first locking member 5, and is sleeved on the outer side of the core rod 1. When the piston cylinder 2 is driven to move the core rod 1 in the direction of the first locking member 5, the fixing member 4 fixes the first locking member 5, and the core rod 1 and the first locking member 5 undergo relative displacement.
[0041] Furthermore, it also includes an elastic member 6. When the fixing member 4 is sleeved on the outside of the core rod 1, the inner wall of the fixing member 4 and the core rod 1 form a limiting groove 401. The elastic member 6 is arranged in the limiting groove 401, and the other end is fixed on the limiting structure 7. When the piston cylinder 2 is driven to move the core rod 1 in the direction of the first locking member 5, the position of the end of the elastic member 6 fixed to the limiting groove 401 remains unchanged, and the end fixed to the limiting structure 7 is squeezed inward, so that the elastic member 6 is deformed and the locking structure is opened; after that, the piston cylinder 2 returns to its original position, and the elastic member 6 rebounds to drive the limiting structure 7 to move the core rod 1 in the direction of the piston cylinder 2, and the locking structure is closed.
[0042] In this embodiment, the elastic member 6 includes but is not limited to a disc spring, which is in the shape of a conical disk. When squeezed, it stores a certain amount of potential energy and releases the potential energy when relaxed to allow one end of the core rod 1 to return to the piston cylinder 2.
[0043] In this embodiment, if Figure 2As shown, it also includes a second locking member 8, and a convex ring 101 is provided at the end of the core rod 1 away from the piston cylinder 2. When the locking structure is closed, the second locking member 8 and the first locking member 5 are engaged with each other, and the lower side of the first locking member 5 abuts against the convex ring 101 of the core rod 1.
[0044] Specifically, the first locking member 5 has elastic force, and the convex ring 101 abuts against the bottom of the first locking member 5 so that the first locking member 5 is engaged with the second locking member 8 upward, wherein the first locking member 5 is deformed by the abutment of the convex ring 101. Specifically, the first locking member 5 and the second locking member 8 are both hook-shaped, and the convex ring 101 abuts against the first locking member 5 so that the first locking member 5 is deformed in the vertical direction, so that the first locking member 5 is hooked with the second locking member 8 upward, and the locking structure is placed in a closed state. When the core rod 1 extends out of the first locking member 5, the convex ring 101 follows the core rod 1 to extend the first locking member 5, and the convex ring 101 separates from the first locking member 5. Since the first locking member 5 loses the influence of the abutment of the convex ring 101, the first locking member 5 rebounds downward, and the second locking member 8 is always fixed in the reel and its position remains unchanged, thereby separating the first locking member 5 from the second locking member 8 and opening the locking structure.
[0045] In addition, this embodiment also provides a rewinding machine, such as Figure 1 As shown, including the above-mentioned locking structure, the rewinding machine 100 includes a transmission mechanism 200, a large plate 300, a reel 400 and a small plate 500 arranged in sequence from back to front, wherein the second locking member 8 is arranged in the reel 400, and the remaining locking structures are arranged in the small plate 500. The transmission mechanism 200 drives the large disk 300 to rotate, and the large disk 300 and the reel 400 share a rotating shaft. When the locking structure is closed, the large disk 300 drives the small disk 500 to rotate, and the rotating shaft of the small disk 500 is the core rod 1. In the prior art, the end face of the core rod 1 is in contact with the piston cylinder 2, so it is easy to wear during rotation. The utility model makes the end of the core rod 1 not in contact with the inner wall of the piston cylinder 2, and a force-bearing structure 3 is sleeved on the outer side of the core rod 1, wherein the force-bearing structure 3 is preferably a bearing, and the bearing is supported between the core rod 1 and the piston cylinder 2 to reduce resistance and facilitate rotation; after the winding work is completed, the unwinding link is entered, and the piston cylinder 2 resists the force-bearing structure 3, avoiding the problem of stress concentration on the end face of the core rod 1, and concentrating the thrust on the force-bearing structure 3, solving the problem of easy wear and stress concentration of the core rod 1 in the prior art that reduces the service life, and the durability is stronger.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
