Description

Technical Field

[0001] This utility model relates to the field of protective sleeve technology, specifically a symmetrical split-type pipe protective sleeve. Background Technology

[0002] Pipe protective sleeves are structural sleeves used to protect internal pipes or cables from external environmental damage (such as mechanical impact, corrosion, high temperature, etc.). They typically employ a spiral corrugated design to enhance mechanical properties and environmental adaptability. They are suitable for the protection and fixation of air conditioning condenser pipes, drainage pipes, heating pipes, gas pipelines, and other industrial pipelines. Existing pipe protective devices mostly adopt an integral structure, which has problems such as the need to disassemble the original pipe connectors during installation, complex operation, poor adaptability to later installation on existing pipes, single fixing method, insufficient seismic performance, and limited applicable pipe types. Therefore, it is necessary to change the pipe protective sleeve to a split structure to facilitate installation.

[0003] Patent document CN216430744U discloses a novel gas pipe wall-penetrating anti-corrosion protective sleeve, specifically relating to the field of protective sleeve technology. It includes an inner sleeve with an outer sleeve on its outer side. Both ends of the outer sleeve are provided with annular baffles. A sealing gasket is fixedly provided on the inner wall of the inner sleeve. Protective layers are fixedly provided at the outer ends of both the inner and outer sleeves. This invention separates the gas pipe from the wall by installing the sleeve at the outer end of the pipe when it passes through a wall. Because the sleeve comprises two layers (inner and outer), it provides better protection compared to the single-layer protection of traditional sleeves. The sleeve is also lighter and has higher hardness, resulting in strong impact resistance. Furthermore, the sleeve has stable performance, low recycling value, and good overall economic benefits.

[0004] However, the aforementioned novel gas-fired wall-penetrating anti-corrosion protective sleeve mainly considers the issues of stable performance, low recycling value, good overall economic benefits, and inconvenience in installing the protective sleeve.

[0005] In view of this, it is necessary to develop a split mechanism to facilitate the installation of the protective sleeve. Utility Model Content

[0006] The purpose of this utility model is to provide a symmetrical split-type pipe protective sleeve to solve the technical problem mentioned in the background art of making the pipe protective sleeve easy to install.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a symmetrical split-type pipe protective sleeve, comprising: a first kit and a second kit, wherein the outer wall of the first kit is provided with a split mechanism, the split mechanism being used to facilitate the installation of the protective sleeve;

[0008] The split mechanism includes reinforcing edges and snap-fit ​​fasteners. The outer walls of the first and second kits are provided with reinforcing edges, and the outer walls of the first and second kits are provided with snap-fit ​​fasteners. The outer walls of both the first and second kits are equipped with fasteners. The snap-fit ​​fastener includes an embedded snap-fit ​​body and an external snap-fit ​​body. The embedded snap-fit ​​body includes a latch and a latching plate. The latching plate is located on the outer wall of the latch. The outer wall of the latch has a latching groove. The outer wall of the latching plate is equipped with a latching ear. The outer wall of the latch is equipped with a latching block. The outer wall of the latching plate is equipped with a latching door. The external snap-fit ​​body includes a latching ear and a tongue. The tongue is located on the outer wall of the latching ear. The outer wall of the tongue is equipped with a latching plate. The inner wall of the latching ear has a latching hole.

[0009] Preferably, the first and second kits are symmetrically divided along an axis, and the reinforcing edges are used to enhance structural strength.

[0010] Preferably, the first and second kits are connected by snap-fit ​​fasteners, and the fasteners are used to secure the connection between the first and second kits and to fix the pipe to the mounting bracket.

[0011] Preferably, the latch and the latch engage to form a main connection, the latch groove and the latch ear cooperate to achieve axial positioning, and the latch block achieves radial locking through the elastic deformation of the latch door.

[0012] Preferably, after the latch is inserted into the tongue, it achieves self-locking through the engagement of the latch plate and the bevel of the buckle hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a split-type mechanism for easy installation of the protective sleeve. First, the first and second sleeves are wrapped around the outside of the pipe. Reinforcing fasteners secure the connection between the first and second sleeves. The latch and snap-fit ​​engage, and the latch groove and snap ear cooperate for axial positioning. The latch block achieves radial locking through the elastic deformation of the latch door, or, after the snap ear is inserted into the tongue, self-locking is achieved through the engagement of the latch plate and the bevel of the latch hole. This completes the connection and fixation of the first and second sleeves to the outside of the pipe without disassembling the pipe. The snap-fit ​​structure eliminates the need for welding, allowing for rapid assembly and reducing construction difficulty. The reinforcing fasteners can simultaneously fix the sleeve and pipe, reducing installation accessories and effectively preventing mechanical damage and corrosion to the pipe, thus extending its service life.
