Description

Technical Field

[0001] The utility model relates to a round pipe plug extraction device, belonging to the technical field of plug disassembly. Background Art

[0002] At present, many devices use the method of matching round tubes with round tube plugs. The round tubes and the plugs are generally matched with interference fit.

How to avoid damage to the plugs when removing the round tube plugs is a problem that technicians in this field have not yet solved. Utility Model Content

[0003] The utility model provides a round tube plug extraction device, which solves the problem that it is difficult to separate the round tube plug from the round tube and the conventional extraction method easily causes damage to the plug.

[0004] The utility model relates to a device for extracting a round pipe plug, comprising two clamping blocks 1 for clamping the plug and two clamping blocks 2 for clamping the round pipe, the two clamping blocks 1 are each provided with a clamping groove 1, the front and rear sides of the two clamping blocks 1 are each provided with a threaded hole 1, a locking bolt 1 is arranged in the threaded hole 1, the two clamping blocks 2 are each provided with a semicircular clamping groove 2, the clamping blocks 2 outside the clamping groove 2 are provided with a threaded hole 2, a knockout bolt is arranged in the threaded hole 2, the front and rear sides of the two clamping blocks 2 are provided with a threaded hole 3, a locking bolt 2 is arranged in the threaded hole 3.

[0005] As a preferred embodiment, the clamping groove 1 is a conical structure with a bottom diameter larger than a top diameter. When the height of the plug is small, the clamping block 1 will not clamp the round tube when clamping the plug, making it easier to remove the plug.

[0006] As a preferred embodiment, a blind ejection hole is provided at the bottom of the clamping block 1, and a polished rod section extending into the blind ejection hole is provided at the top of the ejecting bolt, so that the ejecting bolt can better cooperate with the clamping block 1.

When the clamping block clamps the plug, the non-slip rubber layer can prevent slipping and better avoid damage to the plug. In addition, the non-slip rubber layer is more firmly fixed to prevent delamination.

[0008] As a preferred embodiment, a second anti-skid rubber layer is provided in the second clamping groove, two anti-slip flanges are provided at both ends of the second anti-skid rubber layer, two limiting grooves matching the two anti-slip flanges are provided at both ends of the second clamping groove, a second dovetail-shaped anti-slip groove is provided on the inner wall of the second clamping groove, and two anti-slip hooks matching the second anti-slip groove are provided on the inner wall of the second anti-skid rubber layer. When the second clamping block clamps the round tube, the second anti-skid rubber layer can prevent skidding and better avoid damage to the round tube. In addition, the second anti-skid rubber layer is more firmly fixed to prevent delamination.

[0009] The utility model has the following beneficial effects:

[0010] The plug is clamped by the first of the two clamping blocks, and then the round pipe is clamped by the second of the two clamping blocks, and the plug is pushed out by rotating the ejection bolt, so as to better avoid damage to the plug when it is taken out.
