DETAILED DESCRIPTION

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

They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0023] Furthermore, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0024] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0025] In order to solve the technical problems in the background technology, such as Figure 1-3 As shown, the present application provides a technical solution: an adjustable cable duct elbow structure, the features of which are as follows:

[0026] It is mainly composed of a plurality of connection units 1 connected end to end in sequence. Each connection unit 1 includes a first mounting member 2 and a second mounting member 3. The first mounting member 2 is a square shell having two opposite side surfaces 4, a top surface 5 and a bottom surface 6. The two side surfaces 4, the top surface 5 and the bottom surface 6 enclose a space for accommodating cables. Connection holes 7 are respectively provided on the two side surfaces 4 to facilitate the subsequent installation of the connection unit 1. The second mounting member 3 is connected to the first mounting member 2 and consists of two oppositely arranged side panels 8. The two side panels 8 are arranged parallel to the side surfaces 4 of the first mounting member 2 and are located between the two side surfaces 4. Connection blocks 9 are respectively provided on the two side panels 8, and the connection blocks 9 are adapted to the connection holes 7 on the first mounting member 2.

[0027] When in use, the connection block 9 of the next connection unit 1 can be inserted into the connection hole 7 of the previous connection unit 1, so that the two connection units 1 are hinged. This structure allows the angle of the cable duct elbow to be adjusted according to actual needs to adapt to the installation requirements of different environments.

[0028] Furthermore, the end of the side 4 is designed to be an arc, and its arc radius R is half the height of the side 4. The design of the arc-shaped end allows the side 4 to rotate more smoothly around the hinge axis. Compared with the right-angle design, the hinge axis and the rotating edge of the two connected connection units 1 need to be separated by a larger distance so that they will not be hindered by the next connection unit 1 during rotation. The arc-shaped design of the side 4 makes the connection between the connection units 1 more compact, reduces the gap during movement, and improves the stability of the connection. The hinge axis is located at the center of the arc, which ensures the balance of the connection unit 1 during movement and reduces the vibration and uneven force caused by eccentricity.

[0029] It should be noted that, as shown in the figure, the upper surface of the side panel 8 is parallel to the top surface 5. Its upper surface is smooth and flush with the top surface 5, with no gap, ensuring a compact outer profile. The lower surface of the side panel 8 is also parallel to the bottom surface 6 and is also smooth and flat, forming a flat surface with the bottom surface 6, further enhancing the compact outer profile. The side panel 8 is made of a high-strength material, such as stainless steel, with excellent wear resistance, ensuring the stability and durability of the cable trunking device.

[0030] Furthermore, the protrusion 10 is located at the end of the side plate 8, and the protrusion 10 has three sides, namely a first side 12, a second side 13, and a third side 14. Among them, when the two connected connection units 1 are parallel, the first side 12 abuts against the inner wall of the bottom surface 6 of the next connection unit 1. The limit block 11 is set on the inner wall of the side 4 to limit the rotation between the two connection units 1 around the hinge axis. The design of the protrusion 10 and the limit block 11 enables the two connection units 1 to be connected together at the required angle, thereby improving the overall stability. When the two connected connection units 1 are in a horizontal state, the first side 12 of the next connection unit 1 can abut against the inner wall of the bottom surface 6 of the previous connection unit 1; at the third side 14, the limit block 11 is riveted on the inner wall of the side 4, and the limit block 11 plays a limiting role to prevent the protrusion 10 from further rotating around the hinge axis, thereby achieving the limitation between the two connection units 1. When two connected connection units 1 are not horizontal, the first side 12 of the next connection unit 1 cannot abut the inner wall of the bottom surface 6 of the previous connection unit 1 and can only be limited by the stopper 11. In this case, the stopper 11 can be riveted to the inner wall of the side surface 4 at the third side 14. Due to the effect of gravity, the first mounting member 2 of the next connection unit 1 exerts a downward force, and the protrusion 10 exerts an upward force. The stopper 11 restricts the protrusion 10 from further upward movement.

[0031] It should be noted that the angle between the second side 13 and the third side 14 is an obtuse angle, preferably between 120° and 160°. The second side 13 and the third side 14 are adjacent to each other and are both straight segments, forming an obtuse angle. The obtuse angle design provides greater stability to the protrusion 10 when subjected to force.

[0032] Furthermore, the partition 15 is located in the center of the bottom surface 6 and is perpendicular to the bottom surface 6. The size of the partition 15 matches the internal space of the first mounting member 2, ensuring that the partition 15 can effectively divide the internal space. The partition 15 divides the enclosed internal space of the first mounting member 2 into two non-completely independent spaces, namely the left space and the right space. The left space is used for laying one type of cable, such as communication cables; the right space is used for laying another type of cable, such as power cables. By setting the partition 15, different types of cables can be effectively isolated, mutual interference can be reduced, and the operating efficiency and safety of the cables can be improved.

[0033] It should be noted that the bracket 16 is disposed on the inner wall of the top surface 5, specifically in the center of the top surface 5. The bracket 16 has an arc-shaped hook structure, which is similar in shape to the letter "C", so that the bracket 16 can be securely hooked to the inner wall of the top surface 5. The material of the bracket 16 is preferably stainless steel, which has good corrosion resistance and strength. The bracket 16 is generally fixed by a fixed connection, such as welding or bolting, to ensure that it is not easy to fall off. The bracket 16 can be used to fix special cables, such as fire-fighting cables.

[0034] It should be noted that the side surface 4 is the main body part of the first mounting member 2, and its extension length is relatively long in the first direction, and the first direction is the horizontal direction. The extension length of the top surface 5 in the first direction is shorter than that of the side surface 4. Specifically, the length of the top surface 5 is L1, and the length of the side surface 4 is L2, where L1 < L2. The extension length of the bottom surface 6 in the first direction is also shorter than that of the side surface 4, and the length of the bottom surface 6 is L3, where L3 < L2. The shorter designs of the top surface 5 and the bottom surface 6 are equivalent to adopting discontinuous structures, and ventilation holes or ventilation grooves are formed between two top surfaces 5 or two bottom surfaces 6. The settings of these ventilation holes or ventilation grooves contribute to the heat dissipation and ventilation of the cable.

[0035] It is worth noting that the bottom surface 6 is the stress surface, and the extension length of the bottom surface 6 in the first direction is longer than that of the top surface 5 in the first direction. During the cable laying process, the cable is laid on the bottom surface 6. Since the extension length of the bottom surface 6 is relatively long, the stress area is relatively large, which is beneficial to improving the stress performance of the adjustable wire trough elbow. In addition, the shape of the bottom surface 6 is designed as a plane, which is beneficial to the laying and fixing of the cable.

[0036] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
