Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a high-impact HDPE pipe. Background Technology

[0002] Chinese Patent Application No. 202321273213.2 discloses a modified pipe with high impact resistance, comprising: a pipe body, an inner tube installed at the inner end of the pipe body, symmetrical grooves on both sides of the inner wall of the pipe body, a spring installed in the groove, a limit block installed on the surface of the spring, two slots symmetrically opened on both sides of the surface of the inner tube, the grooves being the same size as the slots; groove blocks installed on both sides of the surface of the pipe body, a spring installed in the inner groove of the groove block, a suction block installed on the surface of the spring, an outer protective block slidably installed on the surface of the groove block; an installation sleeve installed on the surface of the pipe body, an anti-collision pad installed on the surface of the installation sleeve, a buffer block installed between the anti-collision pad and the installation sleeve, and a buffer layer installed in the inner cavity of the inner tube.

[0003] The above-mentioned technology, by sliding an inner slider inside the buffer block and setting a rubber layer at the end of the inner slider, has a certain degree of impact resistance. However, in actual use, since the rubber layer is set inside the mounting sleeve and the mounting sleeve does not have corresponding parts for easy disassembly, it is inconvenient to replace the rubber layer when it ages, and the simple rubber layer has weak impact resistance. Therefore, in order to solve the above-mentioned technical defects, we propose a high-impact HDPE pipe. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-impact HDPE pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-impact HDPE pipe includes an HDPE pipe body. The outer circumference of the HDPE pipe body is provided with several annular mounting grooves. Two sets of symmetrical compression springs are provided in the annular mounting grooves. The ends of the two sets of compression springs away from the mounting grooves are respectively provided with a semi-annular main linkage frame and a secondary linkage frame. One end of the main linkage frame and the secondary linkage frame are hinged by a pin, and the other end of the main linkage frame and the secondary linkage frame are connected by a plug rod.

[0007] Preferably, a rotating ring is rotatably installed in the mounting groove. The outer ring surface of the rotating ring and the inner surfaces of the main linkage frame and the auxiliary linkage frame are provided with positioning holes. The two ends of the compression spring are installed between the rotating ring and the main linkage frame and the auxiliary linkage frame through the positioning holes.

[0008] Preferably, the inner sides of the main linkage frame and the auxiliary linkage frame are provided with a plurality of buffer bladders, which are respectively located between adjacent compression springs.

[0009] Preferably, the outer side of the buffer bag is provided with an adhesive layer, and the buffer bag is connected to the main linkage frame and the secondary linkage frame through the adhesive layer.

[0010] Preferably, the width of the mounting groove is greater than the width of the main linkage frame and the auxiliary linkage frame, and the outer diameter of the main linkage frame and the auxiliary linkage frame is greater than the outer diameter of the HDPE pipe body.

[0011] Preferably, a buffer pad is attached to the outer surface of the linkage frame, and the surface of the buffer pad is a smooth surface.

[0012] Preferably, the outer ring surface of one end of the insertion rod is threaded and connected to the ends of the main linkage frame and the auxiliary linkage frame through the thread, and the unthreaded end of the insertion rod is hexagonal prism-shaped.

[0013] The high-impact HDPE pipe proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the linkage frame compresses the inner springs and buffer bladders along the impact direction of the object. This compression and deformation of the springs and buffer bladders absorbs the kinetic energy of the impact, thus reducing damage to the HDPE pipe. Simultaneously, the rotation of the rotating ring causes the impacting object to fly out, further reducing impact damage to the HDPE pipe. In summary, the HDPE pipe proposed in this solution effectively reduces impact damage caused by external objects impacting the HDPE pipe through the arrangement of several springs and buffer bladders. Furthermore, the rotation of the rotating ring applies a deflection force to the impacting object, causing it to deflect and fly out, further reducing impact damage to the HDPE pipe. Through multiple optimizations, this solution offers higher and more comprehensive impact resistance compared to traditional solutions, thus facilitating the application of HDPE pipes.

[0015] 2. The positioning hole in this utility model facilitates the stable installation of the compression spring between the linkage frame and the rotating ring, thus preventing the compression spring from accidentally falling off during use. The width of the mounting groove is greater than the width of the main linkage frame and the auxiliary linkage frame, allowing the linkage frame to shift not only when the HDPE pipe is impacted vertically, but also when it is impacted horizontally. This enables the HDPE pipe to better cope with impacts from different directions, further improving its impact resistance. The buffer pad further enhances the impact resistance of the HDPE pipe. Since the end of the insertion rod is threaded, it is easy to prevent the insertion rod from detaching from the end of the linkage frame, thus ensuring the stability between the main linkage frame and the auxiliary linkage frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figures 1-6A high-impact HDPE pipe includes an HDPE pipe body 1. The outer ring surface of the HDPE pipe body 1 is provided with several annular mounting grooves 7. Two sets of symmetrical compression springs 2 are provided in the annular mounting grooves 7. The ends of the two sets of compression springs away from the mounting grooves 7 are respectively provided with a semi-annular main linkage frame 3 and a secondary linkage frame 11. One end of the main linkage frame 3 and the secondary linkage frame 11 are hinged by a pin 9, and the other end of the main linkage frame 3 and the secondary linkage frame 11 are connected by a plug rod 4. Example

[0025] Reference Figures 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0026] A rotating ring 5 is rotatably installed in the mounting slot 7. Positioning holes 10 are provided on the outer ring surface of the rotating ring 5 and the inner surfaces of the main linkage frame 3 and the auxiliary linkage frame 11. The two ends of the compression spring 2 are installed between the rotating ring 5 and the main linkage frame 3 and the auxiliary linkage frame 11 through the positioning holes 10. The rotating ring 5 allows for a certain degree of deflection force to be applied to the colliding object as it rotates, preventing the object from being easily deflected by the rotation of the main linkage frame 3 and the auxiliary linkage frame 11 during collision, thus reducing the impact damage to the HDPE pipe body 1. Simultaneously, the positioning holes 10 facilitate the stable installation of the compression spring 2 between the linkage frame and the rotating ring 5, thereby preventing the compression spring 2 from being damaged. The phenomenon of accidental falling during use; the main linkage frame 3 and the auxiliary linkage frame 11 are provided with several buffer bladders 6 on their inner sides. The buffer bladders 6 are located between adjacent compression springs 2. The setting of the buffer bladders 6 means that when the linkage frame is impacted and displaced, that is, when the linkage frame compresses the compression spring 2, the linkage frame also needs to compress the buffer bladders 6. That is, the buffer effect of the linkage frame is further improved under the action of the buffer bladders 6, thereby further improving the impact resistance of the HDPE pipe body 1; the outer side of the buffer bladder 6 is provided with an adhesive layer. The buffer bladder 6 is connected to the main linkage frame 3 and the auxiliary linkage frame 11 through the adhesive layer. The adhesive layer can be an adhesive pad or Velcro, etc., which only needs to serve the purpose of installing and removing the buffer bladder 6 from the linkage frame.

[0027] The width of the mounting groove 7 is greater than the width of the main linkage frame 3 and the auxiliary linkage frame 11, so that the linkage frame can not only be displaced when the HDPE pipe body 1 is impacted in the vertical direction, but also when the HDPE pipe body 1 is impacted in the parallel direction. This allows the HDPE pipe body 1 to better cope with impacts from different directions, thus further improving the impact resistance of the HDPE pipe body 1. The outer diameter of the main linkage frame 3 and the auxiliary linkage frame 11 is greater than the outer diameter of the HDPE pipe body 1. Since the outer surface of the linkage frame 3 is covered with a buffer pad 8, the surface of the buffer pad 8 is a smooth surface. The setting of the buffer pad 8 further enhances the impact resistance of the HDPE pipe body 1. The outer ring surface of one end of the insertion rod 4 is threaded and is connected to the end of the main linkage frame 3 and the auxiliary linkage frame 11 through the thread. The unthreaded end of the insertion rod 4 is hexagonal prism-shaped. Since the end of the insertion rod 4 is threaded, it is easy to prevent the insertion rod 4 from detaching from the end of the linkage frame, thus ensuring the stability between the main linkage frame 3 and the auxiliary linkage frame 11.

[0028] Operating Principle and Advantages: During use, when an external object is launched towards the HDPE pipe 1, i.e., when the object impacts the HDPE pipe 1, the outer side of the linkage frame protrudes beyond the outer side of the HDPE pipe 1, causing the object to first impact the surface of the linkage frame. At this time, the linkage frame compresses the inner compression spring 2 and buffer bladder 6 along the impact direction of the object. This compression deformation of the spring 2 and buffer bladder 6 absorbs the kinetic energy of the impact, thereby reducing the damage caused by the impact on the HDPE pipe 1. Simultaneously, the rotation of the rotating ring 5 applies a certain degree of deflection force to the colliding object, making it easier for the object to deflect due to the rotation of the main linkage frame 3 and the auxiliary linkage frame 11 upon impact. Ultimately, this causes the colliding object to fly out, thereby reducing the impact damage to the HDPE pipe body 1 to a certain extent. In summary, the HDPE pipe proposed in this solution, through the setting of several compression springs 2 and buffer bladders 6, effectively reduces the impact damage caused by external objects colliding with the HDPE pipe body 1. At the same time, by rotating the rotating ring 5, a certain degree of deflection force is applied to the colliding object, causing the colliding object to deflect and fly out, thereby further reducing the impact damage to the HDPE pipe body 1. Thus, through multiple optimizations, this solution has higher and more complete impact resistance compared with traditional solutions, which is beneficial to the application of HDPE pipe body 1.

[0029] It should be further explained that the rotating ring 5 allows the compression spring 2, main linkage frame 3, and auxiliary linkage frame 11 to rotate along the axis of the HDPE pipe body 1 during use. This allows external objects to collide with the main linkage frame 3 and auxiliary linkage frame 11. Specifically, when the main linkage frame 3 and auxiliary linkage frame 11 move in the direction of the collision and compress the compression spring 2, the rotation of the rotating ring 5 can apply a certain degree of deflection force to the colliding object. This ensures that the object is easily deflected by the rotation of the main linkage frame 3 and auxiliary linkage frame 11 during collision, ultimately leading to a deflection of the colliding object. The object flies out, thus reducing the impact damage to the HDPE pipe 1 to a certain extent. At the same time, the positioning hole 10 makes it easy to stably install the compression spring 2 between the linkage frame and the rotating ring 5, thereby avoiding the phenomenon of the compression spring 2 accidentally falling off during use. The buffer bladder 6 means that when the linkage frame is displaced by impact, that is, when the linkage frame compresses the compression spring 2, the linkage frame also needs to compress the buffer bladder 6. That is, under the action of the buffer bladder 6, the buffering effect on the linkage frame is further improved, thereby further improving the impact resistance of the HDPE pipe 1.

[0030] The width of the mounting groove 7 is greater than the width of the main linkage frame 3 and the auxiliary linkage frame 11, so that the linkage frame can not only be displaced when the HDPE pipe body 1 is impacted in the vertical direction, but also when the HDPE pipe body 1 is impacted in the parallel direction. This allows the HDPE pipe body 1 to better cope with impacts from different directions, thus further improving the impact resistance of the HDPE pipe body 1. The setting of the buffer pad 8 further enhances the impact resistance of the HDPE pipe body 1. Since the end of the insertion rod 4 is threaded, it is easy to prevent the insertion rod 4 from detaching from the end of the linkage frame, thus ensuring the stability between the main linkage frame 3 and the auxiliary linkage frame 11.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
