Description

Technical Field

[0001] This utility model relates to a corrugated pipe, and more particularly to a corrugated cable protection pipe cut at the troughs. Background Technology

[0002] Corrugated pipes can be cut at the crests or troughs. Cutting corrugated pipes at the troughs results in problems such as high noise, high power consumption, high material loss, and difficulty in positioning. In order to position the cutting at the troughs, reduce cutting noise, and reduce material loss, this utility model designs a pipe cutter for corrugated cable protection pipes. The cutting point is located at the trough of the corrugated pipe. A steel blade pierces the corrugated pipe to create a cut. The blade is then rotated along the corrugations, and the cut spreads along the rotating blade, thus creating a smooth cross-section along the corrugations without producing debris. Summary of the Invention

[0003] In order to locate the corrugated cable protection pipe at the trough, reduce cutting noise, and reduce pipe material wear during cutting, this utility model designs a pipe cutter for corrugated cable protection pipes, which can be positioned, has no noise, and causes no pipe material loss.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a corrugated cable protection pipe that is cut at the trough is composed of a corrugated cable protection pipe cutter 1 and a corrugated pipe 2.

[0005] The corrugated cable protection pipe cutter 1 consists of a guide rail 11, a blade 12, and a handle 13;

[0006] The bellows 2 consists of crests 21 and troughs 22, and the crests 21 and troughs 22 are alternately wrapped around the outer wall of the bellows 2;

[0007] The guide rails 11 are a pair, located on the left and right sides of the blade 12. The guide rails 11 are composed of guide angles 111 and guide rail connecting bolts 112. The guide angles 111 are arc-shaped, and the arc of the arc is consistent with the arc of the crest 21 of the bellows 2. The two guide rail connecting bolts 112 are used to pull and connect the guide angles 111 on the left and right sides of the blade 12. The guide rails 11 are connected in series at the end of the handle 13 through the two guide rail connecting bolts 112.

[0008] The blade 12 includes a blade edge 121 and a blade connecting bolt 122. The front of the blade edge 121 points towards the trough 22, and the back points towards the center of the arc of the guide rail 11. The blade connecting bolt 122 is located at the end of the blade 12, and the blade 12 is connected to the end of the handle 13 through the blade connecting bolt 122.

[0009] The guide rail 11 and the handle 13 are made of cast iron; the blade 12 is made of 304 stainless steel.

[0010] When cutting the corrugated pipe 2, the trough 22 to be cut is selected, and the blade 121 is embedded in the trough 22. The two adjacent peaks 21 of the trough 22 are surrounded by the two guide angles 111. The blade 121 pierces one point of the trough 22. The guide angles 111 rotate along the arc of the peaks 21 of the corrugated pipe 2, and the blade 121 cuts the trough 22 along the arc guided by the guide angles 111, forming a slit 23 in the middle of the trough 22. When the handle 13 rotates 360°, the blade 12 separates the corrugated pipe 2 along the slit 23. The guide rail connecting bolt 112 and the blade connecting bolt 122 can be adjusted for tightness, making it easy to detach from the handle for maintenance.

[0011] The advantages of this invention are that the kerf deviation is small, the kerf is flat, and the perpendicularity to the corrugated pipe axis is high, and no noise or cutting debris is generated during cutting. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] Figure 2 This is a perspective view of a pipe cutter for corrugated cable protection pipes. Detailed Implementation

[0015] The implementation process is as follows:

[0016] like Figure 1 and Figure 2 As shown, a corrugated cable protection pipe that is cut at the trough consists of a corrugated cable protection pipe cutter 1 and a corrugated pipe 2.

[0017] The corrugated cable protection pipe cutter 1 consists of a guide rail 11, a blade 12, and a handle 13;

[0018] The bellows 2 consists of crests 21 and troughs 22, and the crests 21 and troughs 22 are alternately wrapped around the outer wall of the bellows 2;

[0019] The guide rails 11 are a pair, located on the left and right sides of the blade 12. The guide rails 11 are composed of guide angles 111 and guide rail connecting bolts 112. The guide angles 111 are arc-shaped, and the arc of the arc is consistent with the arc of the crest 21 of the bellows 2. The two guide rail connecting bolts 112 are used to pull and connect the guide angles 111 on the left and right sides of the blade 12. The guide rails 11 are connected in series at the end of the handle 13 through the two guide rail connecting bolts 112.

[0020] The blade 12 includes a blade edge 121 and a blade connecting bolt 122. The front of the blade edge 121 points towards the trough 22, and the back points towards the center of the arc of the guide rail 11. The blade connecting bolt 122 is located at the end of the blade 12, and the blade 12 is connected to the end of the handle 13 through the blade connecting bolt 122.

[0021] The guide rail 11 and the handle 13 are made of cast iron; the blade 12 is made of 304 stainless steel.

[0022] When cutting the corrugated pipe 2, the trough 22 to be cut is selected, and the blade 121 is embedded in the trough 22. The two adjacent peaks 21 of the trough 22 are surrounded by the two guide angles 111. The blade 121 pierces one point of the trough 22. The guide angles 111 rotate along the arc of the peaks 21 of the corrugated pipe 2, and the blade 121 cuts the trough 22 along the arc guided by the guide angles 111, forming a slit 23 in the middle of the trough 22. When the handle 13 rotates 360°, the blade 12 separates the corrugated pipe 2 along the slit 23. The guide rail connecting bolt 112 and the blade connecting bolt 122 can be adjusted for tightness, making it easy to detach from the handle for maintenance.

[0023] Because corrugated pipes have high strength and toughness, the blades are prone to wear and should be sharpened or replaced regularly.
