Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutters, in particular to a PE pipe cutter. Background Art

[0002] PE pipe has good flexibility and chemical resistance. It is widely used in water supply network, irrigation and water diversion projects, agricultural sprinkler projects and other fields. During emergency repair or pipeline maintenance, PE pipe cutters are usually used to temporarily block the gas or water flow in the pipeline. When laying pipelines and repairing broken pipes, PE gas pipes need to be cut. Generally, saw blades are used for cutting, and the cut ends are uneven. However, this method takes a long time to cut and has low work efficiency.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN218462258U proposes a PE pipe cutter, which places the PE pipe to be processed above the triangle of the cutter and between the arc plate, uses a jack to push the balance plate to slide along the bracket, and drives the arc plate to apply downward pressure to the PE pipe, so that the PE pipe is cut off.

[0004] However, although the above-mentioned PE pipe cutter can drive the arc plate through the jack to exert downward pressure on the PE pipe so that the PE pipe is cut by the cutter, when cutting the PE pipe, the PE pipe cutter needs to manually limit the PE pipe to ensure the flatness of the cut surface of the PE pipe. The operation process is time-consuming and labor-intensive, and there is a certain degree of danger. Therefore, the utility model provides a PE pipe cutter to meet the needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a PE pipe cutter.

[0006] The technical problem to be solved by the utility model is to provide a PE pipe cutter to solve the problem that when the existing PE pipe cutter cuts the PE pipe, it is necessary to manually limit the PE pipe to ensure the flatness of the cut surface of the PE pipe, and the operation process is time-consuming, labor-intensive, and there is a certain degree of danger.

[0010] The clamping plate mechanism comprises two clamping plates which are symmetrically and rotatably arranged on the base, and a spring is arranged between the two clamping plates. The clamping plates have an arc-shaped end surface which fits the outer wall of the PE pipe, and a driving component which drives the two clamping plates to rotate relative to each other is arranged on the base.

[0011] Preferably, the drive assembly comprises:

[0012] Two rotating shafts are arranged on the base for relative rotation;

[0014] A driving rod is fixedly connected with the rotating shaft therein.

[0015] Preferably, the clamping plate mechanism is in two groups and is arranged front and back at both ends of the base, and the driving components are also in two groups, and the rotating shafts on the two groups of driving components that are in the same straight line are connected to each other.

[0016] Preferably, the base is provided with a groove for the drive assembly to move.

[0017] Preferably, two limit plates are relatively slidably connected on the base between the driving assembly and the supporting frame, and the opposite end surfaces of the limit plates are arc-shaped surfaces. An adjustment assembly for driving the two limit plates to move relative to each other is provided in the base, and the adjustment assembly includes:

[0018] a threaded rod rotatably disposed on the base;

[0023] In the above scheme, a driving assembly and a clamping plate are provided, and the driving assembly controls the relative rotation of the two clamping plates and the stretching spring. The clamping plate fixes the PE pipe through the tension of the spring, thereby eliminating the need for manual fixation of the PE pipe body, saving time and effort, and reducing the risk of cutting the PE pipe body.

[0024] In the above scheme, by setting an adjustment component, the two sliders are driven to slide relative to each other by rotating the threaded rod, so that the two limit plates move relative to each other and limit the PE pipe body, further improving the stability of fixing the PE pipe body.

[0025] In the above scheme, by providing a rubber pad and a suction cup, the provision of the rubber pad can prevent damage to the PE pipe body when the clamping plate clamps the PE pipe body, and the suction cup can improve the stability between the clamping plate and the PE pipe body.
