Description

Technical Field

[0001] This utility model relates to the field of packaging technology for long poles, and in particular to a fixing clip for wrapping long poles. Background Technology

[0002] Long rods, such as drill collars, are quite long and have an external anti-corrosion coating. To prevent damage to the anti-corrosion coating during transportation, they are often wrapped with a cushioning pad and fitted with a protective shell. This prevents damage to the drill collar's exterior caused by shaking or other factors during transport.

[0003] The aforementioned buffer pad is wrapped around the outer periphery of the drill collar. After wrapping, the joint is sealed with tape to ensure the effective wrapping of the buffer pad around the drill collar. However, during the wrapping process, problems often arise such as the other end of the buffer pad falling off while one end is being wrapped, or the joint being difficult to secure during the sealing process. Utility Model Content

[0004] This utility model provides a fixing clip for wrapping long rods, which solves the shortcomings of the prior art and solves the problem that the buffer pad is inconvenient to fix, thus affecting the wrapping efficiency. It has strong practicality.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0006] A fixing clamp for wrapping a long rod includes a pair of side plates. An end plate is fixed between the outer ends of the side plates by bolts. A threaded sleeve seat is welded to the inner wall of the end plate. A threaded rod is threadedly connected to the threaded sleeve seat. The outer end of the threaded rod is provided with an end head. A cross plate is rotatably provided at the inner end of the threaded rod. Movable rods are provided at both ends of the cross plate.

[0007] A pair of rotating shafts are symmetrically arranged on the inner end of the side plate. A pair of constraint arc arms are rotatably mounted on the rotating shafts. An extension arm is formed on the constraint arc arm. An elongated hole is opened on the extension arm, and a moving rod passes through the elongated hole.

[0008] Furthermore, a gripping rod is provided at the end.

[0009] Furthermore, the inner end of the lead screw is connected to a limit nut via a thread, and the limit nut is located inside the cross plate.

[0010] Furthermore, the two ends of the moving rod and the rotating shaft are axially limited by nuts or cotter pins.

[0011] Furthermore, arc plates are formed on both sides of the constraint arc arm, and threaded blocks are formed on the constraint arc arm. A clamping screw is connected to the threaded block by threads. A rotating cap is provided at the outer end of the clamping screw, and an inner top arc plate is rotatably provided at the inner end of the clamping screw. Multiple rubber protrusions are provided on the inner wall of the inner top arc plate, arranged radially along the inner top arc plate. A bearing is fixed on the outer wall of the inner top arc plate, and the inner ring of the bearing is fixed on the inner end of the clamping screw. Multiple guide bars are provided on the inner top arc plate, and the guide bars pass through the arc plate.

[0012] The advantages of the above technical solution are:

[0013] The inner top arc plate provided by this utility model acts on the buffer pad with its inner wall, thereby achieving the purpose of sealing the buffer pad. In addition, during the sealing process, the position of the inner top arc plate can be adjusted according to the diameter of the long rod by the clamping screw, which expands the scope of application and improves the fixing effect of the buffer pad.

[0014] The constraint arc arm, extension arm, and moving rod provided by this utility model can be used for external protective packaging of long rods of the same specifications. By rotating the lead screw, the constraint arc arm can be rotated inward, thereby quickly pressing the inner top arc plate against the buffer pad and thus quickly achieving the purpose of fixing the buffer pad.

[0018] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 3 . Detailed Implementation

[0019] like Figures 1-3As shown, a fixing clamp for the outer sheath of a long rod includes a pair of side plates 2. An end plate 20 is bolted between the outer ends of the side plates 2. A threaded sleeve seat 22 is welded to the inner wall of the end plate 20. A threaded rod 23 is threadedly connected to the threaded sleeve seat 22. An end head 24 is provided at the outer end of the threaded rod 23, and a holding rod 25 passes through the end head 24. A cross plate 26 is rotatably provided at the inner end of the threaded rod 23. A limit nut 33 is threadedly connected to the inner end of the threaded rod 23. The limit nut 33 is located inside the cross plate 26. Moving rods 27 are provided at both ends of the cross plate 26. A pair of rotating shafts 3 are symmetrically provided on the inner ends of the side plates 2. A pair of constraint arc arms 30 are rotatably provided on the rotating shafts 3. An extension arm 31 is formed on the constraint arc arm 30. An elongated hole 32 is opened on the extension arm 31, and the moving rod 27 passes through the elongated hole 32. The moving rod 27 and the two ends of the rotating shafts 3 are axially limited by nuts or cotter pins.

[0020] Arc plates 34 are formed on both sides of the constraint arc arm 30. Threaded blocks 5 are formed on the constraint arc arm 30. A clamping screw 37 is connected to the threaded block 5 by threads. A rotating cap 38 is provided on the outer end of the clamping screw 37. An inner top arc plate 36 is rotatably provided on the inner end of the clamping screw 37. Multiple rubber protrusions are provided on the inner wall of the inner top arc plate 36, arranged radially along the inner top arc plate. Multiple guide bars 35 are provided on the inner top arc plate 36, and the guide bars 35 pass through the arc plate 34.

[0021] In this embodiment, during operation, the operator first adjusts the position of the inner top arc plate 36 according to the diameter of the long rod. During adjustment, the operator connects the rotating cap 38 with tools such as a wrench, and then rotates the rotating cap 38 and the clamping screw 37 with the wrench or other tools. When the clamping screw 37 rotates, it will drive the inner top arc plate 36 inside to move inward along the length direction of the guide bar 35. During the adjustment process, it is necessary to ensure that the two inner top arc plates 36 are always symmetrical or move equal distances. During the movement, the constraint arc arm 30 is in an open state, and the included angle in the length direction of the outer extension arm 31 is minimal, or even parallel to each other.

[0022] The operator then inserts the gripping rod 25, which facilitates rotation, into the hole on the end 24, and rotates the end 24 and the lead screw 23 through the gripping rod 25. When the lead screw 23 rotates, it will drive the horizontal plate 26 to move inward along the axis of the lead screw 23. When the horizontal plate 26 moves, since the outer extension arm 31 passes through the grooves at both ends, the rotation of the lead screw 23 will drive the horizontal plate 26 to move inward. During the movement, the moving rod 27 acts on the inner wall of the elongated hole 32, thereby increasing the included angle between the outer extension arms 31. As the outer extension arm 31 rotates, the constraint arc arm 30 and the inner top arc plate 36 will gradually close. During the closing process, the rubber convex strip will act on the joint of the buffer pad, thereby achieving the purpose of fixing the buffer pad. The buffer pad can then be fixed by tape.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
