[0019] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further specifically described.

[0020] A quick-install PVC elbow, as Figure 1As shown, the angle ruler is a bent PVC round pipe, including an angle ruler body 1 and a mating cover 2. The angle ruler body 1 is the core of the whole structure. It is made of high-quality PVC material, with good chemical corrosion resistance and electrical insulation, ensuring the safety and durability of the wires. The mating cover 2 is used to cover the inspection opening 1.2 of the angle ruler body 1 to protect the internal wires and provide an inspection position for convenient later inspection of the wires. The two ends of the angle ruler pipe are respectively the wire socket a1.3 and the wire socket b1.4. The cross-sectional diameters of the wire socket a1.3 and the wire socket b1.4 are the same, and the planes where they are located are perpendicular to each other. In order to achieve a smooth turn, the bent part of the angle ruler pipe adopts an arc connection design, abandoning the traditional right-angle connection method and instead using a smooth curve to connect the straight part and the bent part. This arc connection not only provides a more fluent line path but also helps to reduce the stress concentration at the turning point of the line, thus protecting the wires from damage and extending the service life of the wires. The arc connection design also makes the threading and future maintenance of the wires easier because the smooth transition of the arc reduces the friction of the wires at the turning point, making the movement and inspection of the wires easier.

[0021] The angle ruler body 1 is provided with a bent part a1.5 and a bent part b at the bent part. The setting of these two bent parts is to form the inspection opening 1.2, providing the installation space for the inspection opening 1.2 and the placement position for the mating cover 2. The bent part a1.5 is located inside the bend of the angle ruler body 1, and the bent part b is located outside the bend of the angle ruler body 1. The bent part a1.5 and the bent part b are arranged in parallel. The bent part a1.5 and the bent part b respectively extend from the outer tangent planes at the topmost and bottommost ends of the angle ruler body 1, forming arc plates with a longitudinal section that is an arc. The bent part a1.5 and the bent part b have the same width and the same position, ensuring the symmetry and uniformity of the angle ruler body 1 when it is bent. This symmetry is crucial for maintaining the stability of the wires at the bent part because it can reduce the pulling or damage of the wires caused by asymmetry.. The longitudinal sections of the bent part a1.5 and the bent part b are concentric arcs. The diameter of the bent part b is larger than the diameter of the bent part a1.5. The diameter difference between the bent part a1.5 and the bent part b is exactly equal to the diameter size of the angle ruler body 1. This precise dimension design ensures the tight fit of the angle ruler body 1 with the bent part a1.5 and the bent part b, forming a smooth transition curve, thus reducing the stress on the wires at the bent part. The thicknesses of the bent part a1.5 and the bent part d form a flat area. The design of this flat area is to cooperate with the flat area of the mating cover 2, providing a placement position. When the mating cover 2 is tightly fitted with the angle ruler body 1, this flat area can ensure the stability of the cover. At the same time, this also helps to improve the sealing performance of the whole angle ruler, protecting the internal wires from the influence of the external environment.

[0022] The arc ends of the bending part a1.5 and the bending part b are respectively connected to form a fan-shaped inspection port 1.2. The connecting part extends towards the main body part of the angle body 1, and the extending surface is perpendicular to the angle body 1. The bending part a1.5, the bending part b and the two connecting and extending surfaces together form the fan-shaped inspection port 1.2. This inspection port 1.2 is closely connected to the main body part of the angle body 1 to form an integral whole. The plane where the inspection port 1.2 is located is parallel to the vertical plane of the circular pipe of the angle body 1. Such a layout enables the inspection port 1.2 to be perfectly aligned with the wall surface or other supporting surfaces during installation, thus ensuring the convenience of installation and inspection. The straight part of the inspection port 1.2, that is, the connecting part of the bending part a1.5 and the bending part b, is a horizontal line and a vertical line, which are respectively parallel to the plane where the wire socket a1.3 and the wire socket are located. The length of the straight part of the inspection port 1.2 is equal to the diameter length of the circular pipe of the angle body 1. The length and width of the inspection port 1.2 do not exceed the main body of the angle body 1.

[0023] Two mating holes 1.1 are symmetrically arranged at the arc ends of the bending part b, on both sides outside the straight part of the inspection port 1.2. The shape of the mating hole 1.1 is a cylinder. The mating holes 1.1 are located at the top of the circular pipe of the main body part of the angle body 1. They extend towards the main body part of the angle body 1 until they reach the topmost part of the angle body 1 and are smoothly connected to the main body of the angle body 1. The upper surface is flush with the two ends of the bending part b, ensuring the overall consistency and coordination. The width is the same as that of the bending part b. The vertical plane of the mating hole 1.1 and the plane where the flat area of the bending part b is located are in the same plane, and together with the bending part a1.5, the bending part b and the straight part, they form an integrally smooth-connected inspection port 1.2. This smooth-connection design not only improves the aesthetics of the angle body but also makes the wire threading and maintenance work more convenient. The mating holes 1.1 are surrounded by a quasi-cylindrical body. This quasi-cylindrical body serves as the placement and protection body of the mating holes 1.1, ensuring the safety and durability of the mating holes 1.1 during use. The length of the part where the mating holes 1.1 are located along the straight part of the inspection port 1.2 does not exceed one-third of the length of the straight part of the inspection port 1.2, which not only ensures the functionality of the mating holes 1.1 but also avoids excessive interference with the overall structure. The end of the mating hole 1.1 close to the wire socket does not exceed the main body part of the angle body 1.

[0024] The mating cover 2 is also fan-shaped, a fan-shaped plate. The fan shape is composed of a long arc, a short arc and a straight part. This fan-shaped design enables the mating cover 2 to perfectly cover the inspection opening 1.2 and provide protection for the wires at the inspection opening 1.2. The straight part is composed of two straight lines respectively connecting the two ends of the long arc and the short arc. The length of the straight part of the fan shape is equal to that of the straight part of the inspection opening 1.2, that is, both are equal to the diameter length of the circular tube of the angle body 1. This precise dimension matching ensures seamless docking between the mating cover 2 and the inspection opening 1.2. The long arc and the short arc are concentric arcs, and the diameter difference between the two arcs is exactly equal to the length of the straight part of the mating cover 2, ensuring that the bent part of the mating cover 2 can closely fit the bent part a1.5 and the bent part b of the angle body 1. The long arc is located on the outer side of the bent part of the mating cover 2, and the short arc is located on the inner side of the bent part of the mating cover 2. The long arc and the short arc are arranged in parallel. The length of the long arc is equal to the outer length of the longitudinal section of the bent part b, and the length of the short arc is equal to the inner length of the longitudinal section of the bent part a1.5. This precise dimension matching not only ensures the perfect fit between the mating cover 2 and the inspection opening 1.2, but also enables the mating cover 2 to be easily aligned during installation, reducing errors and adjustment time during the installation process.

[0025] On one side of the fan-shaped plate of the mating cover 2, there is a mating step 2.2. The mating step 2.2 is also fan-shaped and is used to closely cooperate with the inspection opening 1.2 and be stuck inside the inspection opening 1.2, so that the mating cover 2 can be more firmly installed on the angle body 1. The mating step 2.2 is also composed of a long arc, a short arc and a straight part, and these elements together form a fan-shaped structure. The straight part is composed of two straight lines respectively connecting the two ends of the long arc and the short arc. The length of the straight part is equal to the length of the straight line inside the straight part of the inspection opening 1.2 and is slightly shorter than the diameter length of the circular tube of the angle body 1. Such a design enables the mating step 2.2 to perfectly embed inside the inspection opening 1.2, providing additional stability and fixity. The long arc and the short arc on the mating step 2.2 are also concentric arcs, and the diameter difference between the two arcs is exactly equal to the length of the straight part of the mating step 2.2. The sides of the fan shape of the mating step 2.2 are parallel to the corresponding sides of the mating cover 2. The length of the long arc of the mating step 2.2 is equal to the arc length inside the bent part b and is less than the length of the long arc of the mating cover 2. The length of the short arc of the mating step 2.2 is equal to the arc length inside the bent part a1.5 and is less than the length of the short arc of the mating cover 2. This size and length setting enables the mating step 2.2 to just be stuck inside the inspection opening 1.2, providing precise fixation. The mating cover 2 is provided with a flat area at the periphery of the mating step 2.2, which is adapted to the flat area of the inspection opening 1.2, enabling the mating cover 2 and the inspection opening 1.2 to be well installed and matched to form a sealed and stable assembly as a whole. It not only improves the convenience of installation, but also enhances the protection function of the mating cover 2 to ensure the safety of the internal wires.

[0026] In the design of the mating cover 2 of a quick - installation PVC elbow, the setting of the two mating columns 2.1 is the key to ensuring the stable connection between the mating cover 2 and the elbow body 1. The two mating columns 2.1 are symmetrically arranged at both ends of the long arc of the mating cover 2, on the outer sides of the straight - line part of the mating cover 2. Such a layout not only provides structural stability but also enables the mating cover 2 to apply pressure evenly during installation, ensuring a tight fit between the mating cover 2 and the elbow body 1. The two mating columns 2.1 are arranged on the fan - shaped annular plate of the mating cover 2 and are on the same surface as the mating step 2.2. The mating cover 2 extends a U - shaped plate at both ends of the long arc. The two U - shaped plates are of the same shape and size and are symmetrically arranged along the axis of symmetry of the fan - shaped annular of the mating cover 2, providing a placement platform for the mating columns 2.1. This not only ensures the stability of the mating columns 2.1 but also enables the mating columns 2.1 to evenly bear the pressure from the mating cover 2. The mating column 2.1 consists of two parts: a cylinder and a hemisphere. The bottom surface of the cylinder is located on the U - shaped plate, providing a stable support point for the mating column 2.1. The hemisphere is located on the top surface of the cylinder, increasing the aesthetics of the mating column 2.1 and also providing additional stability. The mating columns 2.1 are symmetrically arranged along the axis of symmetry of the fan - shaped annular plate of the mating cover 2.

[0027] The height of the mating post 2.1 is less than or equal to the depth of the mating hole 1.1. Such a dimension design ensures that the mating post 2.1 can be fully inserted into the mating hole 1.1, while leaving enough space for easy installation and disassembly. The cross-sectional diameter of the mating post 2.1 is less than or equal to the cross-sectional diameter of the mating hole 1.1. This precise dimension matching not only ensures that the mating post 2.1 can be smoothly inserted into the mating hole 1.1, but also guarantees a tight fit between the two, thus providing a good fixing effect. The shapes and positions of the mating post 2.1 and the mating hole 1.1 are adapted to each other. The mating post 2.1 can be inserted into the corresponding mating hole 1.1 without the need for additional tools or complex operations to achieve the quick installation of the angle cover. The shape and size of the U-shaped plate are the same as the top surface of the cylindrical-like platform of the mating hole 1.1. This design enables the U-shaped plate to perfectly cover the cylindrical-like platform of the mating hole 1.1, thereby providing a stable support point for the mating post 2.1. This design of the U-shaped plate not only enhances the stability of the mating post 2.1, but also simplifies the installation process, allowing users to easily install the angle cover in place. In addition, the design of the U-shaped plate also takes into account the convenience of disassembly and maintenance of the angle cover. Since the U-shaped plate matches the top surface of the cylindrical-like platform of the mating hole 1.1, the angle cover can be easily removed from the angle body 1 by leveraging the U-shaped plate when disassembly is required, facilitating maintenance and inspection. It is not only convenient during installation, but also easy to maintain during long-term use. The design of the mating post 2.1 also considers durability and safety. Since the cross-sectional diameter of the mating post 2.1 is less than that of the mating hole 1.1, the mating post 2.1 will not cause damage to the mating hole 1.1 when inserted, thus ensuring the long-term use of the mating hole 1.1 and the stability of the mating cover 2. At the same time, the height of the mating post 2.1 being less than or equal to the depth of the mating hole 1.1 also ensures that the mating post 2.1 will not protrude after being inserted into the mating hole 1.1, thereby avoiding potential safety hazards.

[0028] The usage and inspection process of a quick-install PVC angle.

[0029] During the construction process, the design of this quick-install PVC angle pipe allows construction workers to install it quickly without complex fixing procedures. The connection between the mating cover 2 and the angle body 1 adopts a quick-locking mechanism. When the mating post 2.1 is installed in the corresponding mating hole 1.1, it means that the mating cover 2 and the angle body 1 are locked successfully, making the installation process more efficient. At the same time, it also reduces the possible dropping of screws and the need to tighten screws during the construction process. Workers can install the angle quickly and simply without using extra tools, which can greatly improve the construction efficiency and effectively reduce the installation cost. Thereby saving valuable construction time and labor.

[0030] The worker inserts the wire into the wire socket a1.3, bypasses the arc elbow, and threads the wire out from the wire socket b1.4. The design of the arc elbow has three advantages. First, it reduces wire damage and increases service life: The design of the arc elbow avoids the bending of the wire at the turning point, thus reducing the physical damage to the wire and extending its service life. Second, the wiring method is more flexible: Compared with straight wiring and traditional right-angle bends, the wiring method of the arc elbow is more flexible, providing more operating space and possibilities for electricians during wiring. Third, wire threading is easier: The design of the arc elbow makes wire threading easier because its arc-shaped structure reduces the resistance of the wire at the turning point, allowing the wire to pass through the elbow more smoothly.

[0031] When it is necessary to inspect or maintain the internal wire, the worker can easily remove the mating cover 2 from the angle body 1. This process does not require any additional tools. Simply hold the U-shaped plate and use the force of the fingers or a slight lever action to disengage the mating post 2.1 from the mating hole 1.1. After the mating cover 2 is removed, the worker can directly observe the condition of the wire through the inspection port 1.2. The inspection port 1.2 provides a clear line of sight, enabling the worker to carefully check the state of the wire, including but not limited to the connection condition of the wire, and whether there are signs of damage or aging. This direct observation method not only improves the inspection efficiency but also enables any potential problems to be promptly discovered and solved. Once the inspection work is completed, the process of re-closing the mating cover 2 onto the inspection port 1.2 is equally simple and quick. The worker only needs to accurately insert the mating post 2.1 into the mating hole 1.1 to complete the installation and reset. This step also does not require any tools, ensuring that the mating cover 2 can quickly and firmly return to its original position. The precise fit between the mating post 2.1 and the mating hole 1.1 ensures a tight connection between the mating cover 2 and the angle body 1, thus guaranteeing the safety of the wire and the overall sealing of the angle. It greatly reduces the time required for maintenance and inspection, allowing the worker to conduct wire inspections more frequently, thereby improving the safety of the electrical system. Secondly, since no tools are used, the risk of damage to the angle body 1 or the mating cover 2 during the operation is also reduced.

[0032] In addition, the material selection and manufacturing process of the angle pipe have also been carefully considered to ensure its durability and reliability in the home decoration environment. PVC material is an ideal choice for manufacturing the angle pipe due to its chemical corrosion resistance, wear resistance, and easy processing characteristics. The inner wall of the angle pipe is smooth, which helps to reduce the friction of the wire during threading and is also convenient for future cleaning and maintenance.

[0033] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
