Description

Technical Field

[0001] The utility model relates to the technical field of PE pipes, in particular to an impact-resistant PE pipe. Background Art

[0002] As we all know, PE, the abbreviation for polyethylene, is generally used for water pipes at temperatures below 40°C and cannot be used for hot water distribution. PE pipe is a highly crystalline, non-polar thermoplastic resin. Raw HDPE has a milky white appearance and exhibits a degree of translucency in thin sections. PE exhibits excellent resistance to most household and industrial chemicals. However, certain chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).

[0003] The patent with application number CN202122341871.8 discloses an impact-resistant PE pipe, including a PE pipe core, an insulation layer, a fireproof layer, a corrosion-resistant coating, an external buffer spring, an impact-resistant pad, a turning connection plate, a rotation groove, a rotation protection sleeve, a turning pipe and a corner protection device. The insulation layer is arranged on the PE pipe core, the fireproof layer is arranged on the insulation layer, the corrosion-resistant coating is arranged on the fireproof layer, the external buffer spring is arranged on the corrosion-resistant coating, and the corner protection device includes a protective shell, a filler storage box, a control valve and a connecting pipe.

[0004] Although the anti-impact pad and external buffer spring of the device have a certain effect of buffering impact force, when the foreign object hits the anti-impact pad in a vertical or near-vertical state, causing the anti-impact pad to be subjected to an impact force in a vertical or near-vertical direction, the impact force is completely transferred to the anti-impact pad, and then completely transferred to the corrosion-resistant coating. However, the device is not equipped with a device to change the movement trajectory of the foreign object when it hits the anti-impact pad. Therefore, it is unable to effectively change and disperse part of the impact force. Therefore, the effect of buffering impact force is not very good, and there is room for improvement.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides an impact-resistant PE pipe with the following beneficial effects:

[0015] When a foreign object hits the rolling ball and the buffer roller of this impact-proof PE pipe, the rolling ball will rotate and the buffer roller will rotate at the same time, causing the foreign object to roll over the rolling ball. To a certain extent, the movement trajectory of the foreign object is changed, thereby unloading part of the impact force and dispersing this part of the impact force to the outside. Then, several springs are used to buffer the remaining impact force, thereby improving a certain buffering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4The utility model is an impact-proof PE pipe, comprising a PE pipe body 1, a protective sleeve 2 is provided on the outside of the PE pipe body 1, which plays a protective role on the PE pipe body 1, a plurality of first threaded holes are provided around the protective sleeve 2, and are all threadedly connected with bolts 3, and the outsides of the plurality of bolts 3 are coated with an anti-corrosion coating to improve the anti-corrosion effect, and the outside of the protective sleeve 2 is fitted with a plurality of support plates 4, and the plurality of support plates 4 are provided with a plurality of second threaded holes, and are all threadedly connected with the corresponding bolts 3, and the first threaded holes are connected with the first threaded holes through the bolts 3 and the second threaded holes. The threaded connection method of the perforations fixes the support plate 4 on the protective sleeve 2. The side wall end faces of several support plates 4 fit together to improve the stability between each other. Several support plates 4 are made of metal materials with good quality. Fixed blocks 5 are respectively provided on both sides of several support plates 4. The middle parts of several fixed blocks 5 are provided with slide grooves 6, and are all slidably connected with slide plates 7. The slide plates 7 slide in the slide grooves 6. The upper parts of several slide plates 7 are all connected to buffer rollers 8 through rotating shafts. When foreign objects hit the buffer rollers 8, the buffer rollers 8 are impacted. The force causes the object to roll, changing the direction of movement of the foreign object, thereby effectively changing the direction of the impact force. A gap is set between the two ends of the several buffer rollers 8 and the inner wall of the slide 7 to prevent the buffer rollers 8 from rubbing against the slide 7 when rotating. The exteriors of the several buffer rollers 8 are coated with a wear-resistant smooth coating to improve their wear resistance and reduce their own friction. The several buffer rollers 8 are all provided with several rolling grooves, and are all connected with rolling balls 9. The rolling balls 9 rotate at multiple angles in the rolling grooves, so that foreign objects can hit the buffer rollers 8 at different angles. When the ball 9 is on the sliding plate 7, the moving direction of the foreign object can be changed at multiple angles. The several rolling balls 9 are made of metal materials with good quality. There is a gap between the several rolling balls 9 and the corresponding slide plates 7 to prevent the rolling balls 9 from rubbing against the slide plates 7 as the buffer roller 8 rotates. One end of the several slide plates 7 is provided with several springs 10, and each is connected to the corresponding support plate 4. When the slide plate 7 is impacted by a foreign object, the impact force is transmitted to the slide plate 7, which slides in the slide groove 6, compressing the several springs 10 to shrink and buffer the impact force.

[0023] To sum up, when using the impact-proof PE pipe, the staff can install multiple support plates 4 on the outer wall of the protective sleeve 2, screw the bolts 3 into the second threaded hole and the first threaded hole, and fix the support plates 4 on the protective sleeve 2. After that, when the foreign object hits the buffer roller 8 and the ball 9, the ball 9 rolls in the corresponding direction according to the different impact angles of the object, changing the running trajectory of the object. At the same time, the impact force drives the buffer roller 8 to roll, and further cooperates with the ball 9 to change the running trajectory of the object. At the same time, the impact force received by the buffer roller 8 is transmitted to the slide 7, driving the slide 7 to slide in the slide groove 6, compressing several springs 10 to contract, and buffering the impact force.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
