Abstract
Description
Technical Field
[0001] This utility model relates to the field of PP pipe technology, specifically to a PP pipe with pressure resistance and impact resistance. Background Technology
[0002] PP pipes are made of polypropylene and have the characteristics of being non-toxic, corrosion-resistant, high-temperature resistant, lightweight, and easy to install. However, the PP pipes currently in use have poor pressure and impact resistance, making them prone to deformation and breakage in some special environments. This necessitates continuous inspection and replacement of PP pipes during installation and use. Therefore, a new type of pipe is needed to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a modified PP pipe with a quick-connect sealing function to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a PP pipe with pressure and impact resistance, comprising a PP pipe body, a first clamping ring, a fixing bolt, a second clamping ring, and a protective outer sleeve. The first clamping ring and the second clamping ring are mirror-symmetrically distributed at the inner sides of both ends of the PP pipe body. The fixing bolt is threaded between the two ends of the first clamping ring and the second clamping ring. The protective outer sleeve is distributed on both sides of the PP pipe body. The two ends of the protective outer sleeve on one side are fixed between the second clamping rings, and the two ends of the protective outer sleeve on the other side are fixed between the first clamping rings.
[0005] Preferably, a buffer pad is clamped and fixed between the protective jacket and the outer wall of the PP pipe.
[0006] Preferably, both the first clamping ring and the second clamping ring are provided with sliding slots, and an auxiliary sliding cover is slidably inserted into the sliding slot.
[0007] Preferably, the auxiliary sliding cover, protective jacket, and buffer pad are all arranged in a semi-circular shape.
[0008] Preferably, the auxiliary sliding cover and the protective jacket are both made of aluminum alloy with a thickness of 1.5-2mm.
[0009] Preferably, the buffer pad is made of nitrile rubber.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This utility model features a protective outer jacket made of aluminum alloy with a thickness of 1.5-2mm as the first line of defense. Utilizing the high strength and ductility of the metal, it disperses external impact forces, preventing stress concentration that could lead to pipe breakage. A nitrile rubber buffer pad absorbs impact energy through elastic deformation, reducing instantaneous pressure transmission to the PP pipe and preventing brittle fracture. A reinforcing layer with a sliding auxiliary cover enhances the level of protection. The protective outer jacket, buffer pad, and auxiliary cover are all detachable semi-circular structures, allowing for quick assembly via clamping rings and bolts during installation without replacing the entire pipe. The protection level can be freely selected based on the actual impact risk. Mirror-symmetrical clamping rings are secured with bolts to ensure a tight fit between the protective layer and the PP pipe, preventing displacement. The sliding groove design allows for seamless connection between the auxiliary cover and the clamping rings, enhancing overall integrity. The nitrile rubber buffer layer is oil-resistant, aging-resistant, and exhibits excellent elasticity, effectively absorbing vibration energy. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3The present invention provides an embodiment of a PP pipe with pressure and impact resistance, comprising a PP pipe body 2, a first clamping ring 3, a fixing bolt 4, a second clamping ring 5, and a protective outer sleeve 7. The first clamping ring 3 and the second clamping ring 5 are mirror-symmetrically distributed at the inner sides of both ends of the PP pipe body 2. The fixing bolt 4 is threaded between the two ends of the first clamping ring 3 and the second clamping ring 5. The protective outer sleeve 7 is distributed on both sides of the PP pipe body 2. The two ends of the protective outer sleeve 7 on one side are fixed between the second clamping rings 5, and the two ends of the protective outer sleeve 7 on the other side are fixed between the first clamping rings 3.
[0018] A buffer pad 8 is clamped and fixed between the protective jacket 7 and the outer wall of the PP pipe body 2.
[0019] Both the first clamping ring 3 and the second clamping ring 5 are provided with sliding slots 6, and an auxiliary sliding cover 1 is slidably inserted into the sliding slot 6.
[0020] The auxiliary sliding cover 1, the protective jacket 7, and the buffer pad 8 are all semi-circular, which can fully wrap and protect the PP pipe body 2.
[0021] Both the auxiliary sliding cover 1 and the protective jacket 7 are made of aluminum alloy with a thickness of 1.5-2mm, providing adequate protection.
[0022] The buffer pad 8 is made of nitrile rubber. The buffer pad 8 absorbs impact energy through elastic deformation, reduces the instantaneous pressure transmitted to the PP pipe body 2, and prevents the pipe body from cracking due to brittle deformation.
[0023] Working principle: After the buffer pads 8 are attached to both sides of the PP pipe body 2, the buffer pads 8 wrap around the outside of the PP pipe body 2. Then, the symmetrically distributed protective outer sleeves 7 further attach and wrap around the PP pipe body 2 and the buffer pads 8. Then, the fixing bolts 4 securely connect the first clamping rings 3 and the second clamping rings 5 at both ends of the protective outer sleeve 7, so that the protective outer sleeve 7 can firmly wrap and fix the buffer pads 8 and the PP pipe body 2, providing sufficient protection for the PP pipe body 2. The protective outer sleeve 7, which wraps around the PP pipe body 2, serves as the first protective layer. Utilizing the high strength of aluminum alloy, the local impact force is quickly dispersed to the entire tube surface, avoiding tube breakage caused by stress concentration. The buffer pad 8 located between the protective jacket 7 and the PP tube 2 absorbs impact energy through elastic deformation, reducing the instantaneous pressure transmitted to the PP tube 2 and preventing the tube from cracking due to brittle deformation. Furthermore, depending on the protection level, the auxiliary sliding cover 1 can be slid into the interior of the second clamping ring 5 and the first clamping ring 3 through the sliding groove 6, so that the auxiliary sliding cover 1 is located on the outside of the protective jacket 7, further increasing the protection level of the PP tube 2.
[0024] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
