Description

Technical Field

[0001] This utility model belongs to the field of threading technology, specifically relating to a thread groove with a hinge. Background Technology

[0002] Cable trays are widely used cable management devices in construction, industrial, and commercial sectors, primarily for protecting and guiding cable lines. Traditional cable trays typically consist of a base and a cover plate, with the cover plate fixed to the base via clips, sliding, or direct embedding. However, traditional cable tray covers are prone to sliding or detaching during installation and removal, especially in vertical installations or complex wiring environments, causing inconvenience and increasing the difficulty of construction and maintenance. Over time, clip-on or embedded covers may loosen due to vibration or environmental changes, leading to exposed cables and reduced safety. Furthermore, traditional cable tray covers are prone to gaps or deformation during frequent opening and closing or operation, affecting the appearance of the cable tray and the neatness of the wiring. With the increasing demand for parallel installation of high-voltage and low-voltage lines, cable trays require higher reliability and stability to avoid cable interference or safety hazards caused by loose covers.

[0003] For example, there is a Chinese patent with publication number CN220401357U, which relates to a wire trough with a hinge structure, including an integrated wire trough. The integrated wire trough includes a support plate, a first binding plate is fixedly connected to one side of the top of the support plate, and two fasteners are fixedly connected to the bottom of the support plate. An integrated plate cover and the integrated wire trough are used in conjunction with each other. The integrated plate cover includes a sealing cover, which is rotatably connected to the first binding plate through a bending hinge. A second binding plate is fixedly connected to the other side of the top of the support plate, and a sealing strip is fixedly connected to one side of the top of the sealing cover. The sealing strip matches the second binding plate. This utility model utilizes the combined use of an integrated cable tray, an integrated cover, and a bending tie. The integrated cover, in conjunction with the integrated cable tray, can bind and organize the cable harness. Under the action of the bending tie, the integrated cover can rotate relative to the integrated cable tray to open or close, and a loose integrated cover will not fall off or be lost. However, the Chinese patent with publication number CN220401357U is applicable to the automotive parts field and cannot meet the needs of cable management in construction and industry. Furthermore, it requires multiple bends, blocks, and buckles for fixation, resulting in a complex structure, high processing costs, low maintenance efficiency, and lack of ease of installation. Utility Model Content

[0004] To address the issues of low reliability and stability in cable trays, this invention proposes a hinged cable tray. By introducing a hinge structure between the bottom tray and the cover plate, the cover plate can maintain a permanent connection with the bottom tray, thereby significantly improving the ease of installation, structural stability, and service life of the cable tray. This not only improves construction efficiency but also enhances the reliability and aesthetics of the cable tray, meeting the cable management needs in complex environments.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wire groove with a hinge.

[0006] The device includes a cable tray cover and a cable tray bottom. The edge of the cable tray cover is provided with a cantilever buckle head, and the side wall of the cable tray bottom is provided with a limit buckle. The cantilever buckle head and the limit buckle are matched. The first end of the cable tray cover is connected to a hinge, which connects the cable tray cover and the cable tray bottom, so that the cable tray cover can rotate and open relative to the cable tray bottom.

[0007] In this technical solution, a hinge is used to achieve an integrated connection between the cable tray cover and the cable tray bottom, allowing the cable tray cover to rotate freely relative to the cable tray bottom and open and close. This effectively prevents the cable tray cover from separating or being lost during opening, closing, or maintenance. The precise cooperation between the cantilever buckle head and the limit buckle ensures that the cover plate and the bottom groove are tightly connected, preventing loosening or falling off and improving the stability of the structure and the safety of use.

[0008] Preferably, the groove cover includes a rectangular, flat, plate-shaped middle portion, the middle portion having a first side and a second side that are not adjacent, and the first side and the second side of the middle portion extending perpendicularly to the rectangular plate to the same side having a first bend and a second bend to form a semi-enclosed structure.

[0009] Preferably, the cantilever buckle head is an elastic structure, located at the first end of the cable tray cover, and can quickly engage and disengage with the limiting buckle through elastic deformation. The angle between the beam and the wall of the cantilever buckle head on the hook claw side is an acute angle.

[0010] Preferably, the limiting buckle has a groove structure, and the cantilever buckle head is engaged in the limiting buckle, so that the wire groove cover is tightly connected to the bottom of the wire groove.

[0011] Preferably, the hinge is an external hinge, fixedly connected to one end of the cable tray cover and the cable tray bottom. The hinge includes a rotating shaft and two connecting arms, which are fixedly connected to the cable tray cover and the cable tray bottom, respectively.

[0012] Preferably, the hinge is a built-in hinge, hidden inside the cable tray cover and the cable tray bottom, and a hinge mounting groove is provided at the connection between the cable tray cover and the cable tray bottom, and the hinge is installed in the mounting groove.

[0013] Preferably, the cable tray cover and the cable tray bottom are provided with a plurality of cantilever buckle heads and limit buckles along the length direction, and the cantilever buckle heads and limit buckles are evenly distributed along the length direction of the cable tray.

[0014] Preferably, the bottom of the wire trough is provided with a plurality of fixing holes for fixing the wire trough to the mounting surface by bolts.

[0015] Preferably, the first bent portion is connected to a connector, and the connector is fixedly connected to the bottom of the groove.

[0016] Preferably, the outer surface of the cable tray cover is provided with an anti-slip texture, and the inner surface of the bottom of the cable tray is provided with a cable fixing groove for fixing the cable and preventing the cable from shifting.

[0017] The beneficial effects of this utility model are:

[0018] 1) The hinge design enables the cable tray cover to be integrated with the bottom of the cable tray, which simplifies the installation operation and ensures the flexibility of the cable tray cover during opening and closing. It can rotate freely, which facilitates the inspection and maintenance of cables.

[0019] 2) The precise fit between the cantilever buckle head and the limit buckle ensures that the cover plate and the bottom groove are tightly connected, preventing loosening or falling off, and improving the stability of the structure and the safety of use.

[0020] 3) The hinge's anti-loss design effectively prevents the traditional cable tray cover from separating and being lost during opening, closing, or maintenance, significantly improving the product's practicality and reliability. Attached Figure Description
