DETAILED DESCRIPTION

[0018] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0021] Example 1

[0022] In this embodiment, a PE corrugated pipe tensile strength testing device is proposed. Figure 1-Figure 4 The PE corrugated pipe tensile strength testing device includes a base 1, and there are two columns above the base 1, which are a screw lifting unit 2 and a limit unit 3. There is a second beam 5 between the screw lifting unit 2 and the limit unit 3. The second beam 5 is driven by the screw lifting unit 2 and constrained by the limit unit 3. The second beam 5 is equipped with a first wedge clamp 7, and the base 1 is equipped with a second wedge clamp 11. The first wedge clamp 7 and the second wedge clamp 11 are responsible for clamping the two ends of the PE corrugated pipe.

[0023] In this embodiment, the screw lifting unit 2 is an existing known technology, which usually has a screw structure and is equipped with a driving part such as a servo motor. The limiting unit 3 is a supporting structure of the screw lifting unit 2. Its function is to constrain the second beam 5 to be limited to up and down movement when the screw structure drives the second beam 5 to move up and down without rotating or other movements.

[0024] See also Figure 1 There is also a first crossbeam 4 between the screw lift unit 2 and the limit unit 3. The first crossbeam 4 is located above the second crossbeam 5. Its function is to cooperate with the base 1 to strengthen the structural strength of the screw lift unit 2 and the limit unit 3 to prevent accidents such as the unit tipping over. In addition, it should be added that the second crossbeam 5 is equipped with a sensor 9. After the first wedge clamp 7 and the second wedge clamp 11 clamp the PE corrugated pipe, the sensor 9 moves the second crossbeam 5 through the screw lift unit 2 to detect the tensile strength of the PE corrugated pipe.

[0025] Please continue reading Figure 1-Figure 4 The first wedge-shaped clamp 7 is installed at the bottom of the second crossbeam 5 through the first fixing part 6, and the second wedge-shaped clamp 11 is fixed on the top of the base 1 through the second fixing part 10. It should be noted that the first fixing part 6 and the second fixing part 10 are sleeve structures, which can be used to fix the corresponding wedge-shaped clamps with the help of the pins. In addition, the axes of the first fixing part 6 and the second fixing part 10 coincide, and their function is to make the PE corrugated pipe clamped by the first wedge-shaped clamp 7 and the second wedge-shaped clamp 11 perpendicular to the horizontal plane.

[0026] See also Figure 2The first wedge clamp 7 and the second wedge clamp 11 are known technologies. Further description: In this embodiment, the wedge clamp consists of a clamp body, two clamping blocks, a T-shaped rack, a gear and a spring. The clamping process can be briefly described as squeezing the spring by rotating the gear to form a space for clamping between the two clamping blocks. After the PE corrugated pipe is clamped, the PE corrugated pipe is fastened between the two clamping blocks based on the pressure provided by the spring and the tensile force generated in the subsequent measurement of tensile strength.

[0027] Please continue reading Figure 2 , personnel hold the handle 8 to rotate the gear. The function of the handle 8 is not limited to holding, but can also cut the PE corrugated pipe. Please refer to Figure 3 and Figure 4 The handle 8 includes a handle body 81, wherein the outward end side of the handle body 81 has a first groove 82 and a second groove 83, and a tool fixing portion 84 is installed in the first groove 82. Of course, the tool fixing portion 84 is equipped with a tool 85; the first groove 82 is connected to the second groove 83, and the second groove 83 has an opening, which gradually narrows to the connection between the first groove 82 and the second groove 83, so that the PE corrugated pipe entering the first groove 82 from the connection is cut in a flat style by the tool 85.

[0028] In this embodiment, the handle 8 can easily cut PE corrugated pipes, with the following advantages: First, the cutter 85 is positioned within the first groove 82, which has a depth. This eliminates the risk of safety hazards even if the cutter 85 is exposed when a person grips the handle body 81. Second, the opening to the junction between the first groove 82 and the second groove 83 gradually narrows. This feature allows PE corrugated pipe within the cutting range of the cutter 85 to be cut flat, thereby improving cutting efficiency and ensuring a smooth and complete cut.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
