Description

Technical Field

[0001] This invention belongs to the field of pipe technology, specifically relating to a line protection device for installation at an angle and its installation method. Background Technology

[0002] During the temporary or later installation of electrical equipment, for cost and schedule considerations, conduit is often used to protect and fix the cables. This type of square or round PVC conduit is suitable for most scenarios. However, because it protrudes from the wall, it is not aesthetically pleasing. There are also many safety hazards caused by the conduit being damaged by impacts or scratches, resulting in the conduit or even the cable being broken.

[0003] Patent CN205207917U discloses a multifunctional PVC pipe fitting for wall corners. The pipe body has a right-angled triangular cross-section and is equipped with two partition strips inside. The interior of the pipe body is divided by partition strips one and two to form a water pipe cavity, a threading cavity one, and a threading cavity two. The water pipe cavity is located at the right angle corresponding to the pipe body cross-section, while threading cavities one and two are located at the two acute angles corresponding to the pipe body cross-section. Partition strips one and two intersect at the hypotenuse corresponding to the pipe body cross-section. This fitting is suitable for installation at wall corners. The water pipe cavity is used as a drain pipe or a water inlet pipe, while threading cavities one and two are used as threading conduits. By placing the right angle corresponding to the pipe body cross-section close to the wall corner, threading cavities one and two form a sound-absorbing structure on both sides of the water pipe cavity, which can reduce some water flow noise. The problems with this fitting are that the installation process may damage the water pipe cavity, the water flow noise in a square water pipe cavity will be more obvious, and the square water pipe cavity is difficult to withstand high water pressure, resulting in a shorter lifespan compared to a round water pipe; furthermore, integrating the electrical wires and water into the same pipeline poses certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide an impact-resistant, aesthetically pleasing, and safe line protection device for installation at angles, and its installation method.

[0005] To achieve the above objectives, the present invention discloses a line protection device for installation at a corner. The line protection device is used to protect and fix exposed cables at the right angle of a wall corner, step, or curb. The line protection device includes an external triangular tube and a flexible tube inside the triangular tube. The cross-section of the triangular tube has two right-angled sides and a thickened inclined side. The outer side of the flexible tube is provided with radially evenly distributed protrusions or support plates.

[0006] Preferably, the outer surface of the inclined side is a concave arc surface.

[0007] Preferably, the outer side of the inclined edge is provided with a decorative layer.

[0008] Preferably, the decorative layer is a coating or a sticker.

[0009] Preferably, the height of the protrusion or support piece is not less than 3mm.

[0010] Preferably, the triangular tube is made of an impact-resistant rigid polymer material.

[0011] Preferably, the thickness of the bevel is not less than 2 mm.

[0012] Preferably, the hose is made of insulating material.

[0013] An installation method for a line protection device installed at an angle involves selecting a triangular tube that matches the color of the decorative layer and the installation environment. First, the corner of the building is cleaned, and the triangular tube is fixed by adhesive bonding or by drilling holes near the edge of the bevel and nailing in fasteners. After the triangular tube is fixed, the cable is threaded into a flexible conduit, and then the cable with the conduit is threaded into the triangular tube. Subsequently, both ends of the flexible conduit are sealed, and the gaps created by installing the triangular tube are sealed.

[0014] Preferably, after the cable with the flexible tube is inserted into the triangular tube, the cable is pulled to swing slightly left and right or up and down to prevent the protrusions or support plates of the flexible tube from collapsing when multiple cables or multiple flexible tubes are inserted at the same time, so that the protrusions or support plates support the cable.

[0015] The line protection device and its installation method for installation at angles according to the present invention have at least the following advantages:

[0016] 1. The line protection device adopts an invisible design. Its small size with two right-angled sides and one curved bevel allows it to perfectly utilize the angles of corners, steps, curbs, etc., without leaving any protrusions on flat walls or bricks. The presence of the decorative layer and the concave bevel allow the line protection device to blend well with the surrounding environment without damaging the overall landscape.

[0017] 2. The small cross-sectional size of the triangular tube, placed at the angle, makes it difficult for cars, electric vehicles, or pedestrians to damage it unless intentionally vandalized. In addition, the thickened and concave hypotenuse allows the triangular tube to better withstand impacts and prevent damage.

[0018] 3. The flexible hose provides further buffering, waterproofing, and insulation protection for the cable. Furthermore, due to the presence of protrusions or support plates, there is a certain distance between the cable and the inner wall of the triangular tube in all directions. This not only enhances the insulation effect but also minimizes the contact between the flexible hose and water when the triangular tube is damaged and water enters, thus providing better protection for the cable. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the cross-sectional structure of a line protection device.

[0020] The diagram is labeled as follows: triangular tube 1, curved surface 101, decorative layer 102, right angle side 103, hypotenuse 104, flexible tube 2, and support plate 201. Detailed Implementation

[0021] The present invention will be further described in detail below through embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] like Figure 1 As shown, a line protection device is used for installation at a right angle. The line protection device is used to protect and fix exposed cables at the right angle of a wall corner, step or curb. The line protection device includes an external triangular tube 1 and a flexible hose 2 inside the triangular tube. The cross-section of the triangular tube 1 has two right-angled sides 103 and a thickened hypotenuse 104. The hypotenuse is thickened to be more impact resistant.

[0024] The outer side of the hose 2 is evenly provided with radially distributed protrusions or support plates 201. Currently, it is relatively easier to implement in production to provide support plates throughout the outer side of the hose 2, and the support is also better.

[0025] The outer surface of the hypotenuse is a concave arc surface 101. The concave arc surface can better reduce the probability of the triangular tube 1 being impacted by external forces, and setting the hypotenuse as a curved panel can also better buffer impacts.

[0026] The outer surface of the inclined side is provided with a decorative layer 102, which can be a coating or a sticker. Since only the outer surface of the inclined side is exposed after installation, the decorative layer allows the circuit protection device to blend into the surrounding environment.

[0027] The height of the protrusion or support piece is not less than 3mm, and the triangular tube is made of impact-resistant rigid polymer material. The thickness of the bevel is not less than 2mm, and the specific required thickness depends on the application scenario.

[0028] The hose 2 is made of insulating material.

[0029] An installation method for a line protection device installed at an angle involves selecting a triangular tube 1 that matches the color of the decorative layer and the installation environment. First, the corner of the building is cleaned. The triangular tube is then fixed by adhesive bonding or by drilling holes near the edge of the hypotenuse and inserting fasteners. Nailing directly into the near edge of the hypotenuse, or drilling holes and then fixing a sharp angle portion of the triangular tube with screws, does not affect the space inside the triangular tube used to accommodate the flexible conduit. Furthermore, drilling holes from near the edge of the hypotenuse towards the opposite right-angle side, with the final fixing point near the right angle of the triangular tube, provides a better fixing effect.

[0030] After the triangular tube 1 is fixed, the cable is threaded into the flexible conduit 2, and then the cable with the conduit is threaded into the triangular tube. The ends of the flexible conduit are then sealed, and any gaps created during the installation of the triangular tubes, such as the joints between adjacent triangular tubes, the openings at both ends of the triangular tubes, and gaps created by drilling, are sealed with adhesive. This provides waterproofing and moisture protection, and also prevents insects and rodents from gnawing or drilling in. After the cable and line protection device are installed, before sealing, the cable is pulled slightly left and right or up and down to prevent the protrusions or support plates 201 of some flexible conduits from collapsing when multiple cables or flexible conduits are installed simultaneously. The protrusions or support plates should support the cable.

[0031] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and embodiments shown and described herein.
