Description

Technical Field

[0001] This utility model relates to the field of building electrical engineering technology, specifically to an adjustable-angle cable tray bend. Background Technology

[0002] In building electrical construction, the arrangement of cable trays is often limited by the building's structural space, especially in narrow areas such as equipment floors and pipe shafts, where bending structures are needed to change the direction of the cable trays. In related technologies, cable tray bending often uses prefabricated bends with fixed angles (such as 45° or 90°).

[0003] Regarding the aforementioned technologies, since the cables are laid inside the cable tray, it is difficult to ensure that the shape of the bend at a fixed angle perfectly matches the cable tray. The cable often bulges out of the cable tray at the bend, which is difficult to meet the needs of complex construction environments and results in insufficient flexibility of cable tray bending. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle cable tray bend to solve the problem of insufficient flexibility in cable tray bending.

[0005] To achieve the above objectives, the present invention provides an adjustable-angle cable tray bend using the following technical solution:

[0006] An adjustable-angle cable tray bend includes a fixed component and a movable component. The fixed component has a positioning groove in an arc shape. The movable component has at least two positioning holes arranged in an arc shape and positioning bolts passing through the positioning holes. The positioning bolts can slide along the positioning groove to adjust the angle between the movable component and the fixed component. A shape retainer is provided inside the fixed component for cable insertion.

[0007] As an optimization of the adjustable-angle cable tray bend, the shape retainer is bendable and the angle is adjustable, and the bending angle of the shape retainer is synchronously matched with the included angle between the movable part and the fixed part.

[0008] As an optimization of the adjustable angle cable tray bend, the fixing component includes one of the cable tray tee and the cable tray tee.

[0009] As an optimization of the adjustable-angle cable tray bend, the inner wall of the shape fixer is provided with anti-slip texture.

[0010] As an optimization of the adjustable-angle cable tray bend, the shape retainer is made of flame-retardant PVC.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] (1) Significantly improved space utilization: Through the continuous angle adjustment function, the bending angle (such as 30°, 60°, etc.) can be flexibly selected according to the actual space constraints, which reduces the space occupation by 20%-40% compared with the traditional fixed angle scheme, and is especially suitable for narrow areas such as equipment floors and pipe shafts.

[0013] (2) Enhanced cable fixing reliability: The shape fixer is matched synchronously with the bend angle, and combined with the internal anti-slip texture design, it effectively prevents the cable from bulging, and the construction acceptance pass rate is increased to over 98%.

[0014] (3) Construction efficiency and cost optimization: No need to prefabricate multiple angle bends, a single product can be adapted to multiple scenario needs, reducing inventory costs; simple operation, shortening the construction cycle by about 30%.

[0015] (4) Safety assurance: Flame-retardant materials and structural design comply with building electrical engineering safety standards, reducing the risk of fire. Attached Figure Description

[0020] To make the technical solution and advantages of this utility model clearer, the present utility model and its beneficial effects will be described in further detail below with reference to specific embodiments and accompanying drawings. However, the embodiments of this utility model are not limited thereto.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail below.

[0024] This application provides an adjustable-angle cable tray bend, employing the following technical solution:

[0025] Reference Figure 1 and Figure 2The cable tray bend includes a fixed component 1 and a movable component 2. The fixed component 1 is a bend pipe with multiple directional openings. Specifically, the type of fixed component 1 includes at least cable tray tee bend pipes such as cable tray two-way bends and cable tray three-way bends. Positioning grooves 3 are formed on the sides of two adjacent openings of the fixed component 1. The positioning grooves 3 are arc-shaped, extending from one opening to the other; specifically, the positioning grooves 3 are quarter-circle arcs. The movable component 2 is a straight square tube. At least two positioning holes 4 are formed on the side of the movable component 2. The positioning holes 4 are arranged in an arc shape, and the arc shape of the positioning holes 4 matches the arc shape of the positioning grooves 3. Positioning bolts 5 are installed in the positioning holes 4, inserted into the positioning grooves 3, and slide along the positioning grooves 3. As the positioning bolts 5 slide, the movable component 2 can move from one opening of the fixed component 1 along an arc towards the other opening of the fixed component 1. The angle between the movable component 2 and the fixed component 1 can be adjusted according to the cable installation requirements, with an adjustment range of 0° to 90°. The fixed component 1 is also equipped with a shape retainer 6, which is cylindrical. When the cable is inserted into the fixed component 1, it is installed inside the shape retainer 6. The shape retainer 6 guides the cable from one opening of the fixed component 1 to the opening of the movable component 2, while simultaneously limiting and fixing the shape of the cable to prevent it from bulging. By locking the positioning bolt 5 at different positions within the positioning groove 3, the angle between the movable component 2 and the fixed component 1 can be locked at any angle from 0° to 90°. This allows for flexible selection of the bending angle according to actual space constraints, reducing space occupation and making it suitable for narrow areas, thereby improving the flexibility of cable tray bends.

[0026] In a preferred embodiment of this application, the shape retainer 6 is elastic and bendable. The bending angle of the shape retainer 6 is synchronously matched with the angle between the movable part 2 and the fixed part 1, making the cable transition smoother, reducing the space occupied, and thus improving the flexibility of cable arrangement. Specifically, the shape retainer 6 is made of flame-retardant PVC, which not only has good fire resistance and heat resistance but also good strength and toughness, thereby improving the reliability of cable fixing and reducing the risk of fire.

[0027] Furthermore, the shape retainer 6 has an integrally formed anti-slip texture inside, which can be wavy or toothed, and is not limited here. The anti-slip texture contacts the outer sheath of the cable, effectively reducing the slippage of the cable relative to the shape retainer 6, which helps to improve the limiting effect of the shape retainer 6 on the cable and further improves the reliability of cable fixation.

[0028] The experimental principle of this application embodiment is as follows: When it is necessary to adjust the bending angle of the cable tray, loosen the positioning bolt 5, slide the movable part 2 along the positioning groove 3 to the target angle, and then tighten the bolt. This allows the movable part 2 and the fixed part 1 to form a connecting pipe at any angle from 0° to 90°, breaking through the limitation of fixed angle in traditional specifications. It enables continuous angle adjustment, thereby improving the flexibility of cable tray bend layout.

[0029] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
