Description

Technical Field

[0001] This utility model relates to the field of profile technology, and in particular to an aluminum alloy profile with integrated cable trays. Background Technology

[0002] Aluminum alloy profiles are widely used in automated equipment frames, production lines, architectural decoration, and electronic device housings due to their advantages such as light weight, high strength, corrosion resistance, and ease of processing and forming. In these applications, the hollow structure of aluminum alloy profiles is often used as cable trays to house and protect various wires, cables, or data harnesses, thus providing both structural support and wiring functionality.

[0003] When placing wire harnesses inside cable trays in aluminum alloy profiles, effective securing is essential to prevent them from shifting, tangling, or rubbing against the inner wall of the profile due to equipment vibration or their own weight. Currently, methods for achieving this are limited. Technicians typically use plastic cable ties to bundle the wire harnesses in sections before placing them into the cable tray. However, cable ties are usually for single use. When subsequent maintenance, adjustments, or additions / removals of wire harnesses are needed, the old cable ties must be cut and replaced with new ones, making the process cumbersome and difficult to control the binding force.

[0004] To facilitate repeated opening and closing, some improved cable trays employ simple snap-on clamps. Users can place the cable harness inside the clamp and then press to engage the clip. However, this simple snap-on structure often relies solely on the elastic deformation of the material itself for locking, resulting in limited locking force. When faced with thicker, stiffer cable harnesses or under prolonged equipment vibration, the clips are prone to elastic fatigue or accidental loosening, causing the cable harness to become tangled again, losing its reliable securing function and posing a safety hazard.

[0005] Therefore, this utility model proposes an aluminum alloy profile with integrated cable trays to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an aluminum alloy profile with integrated wire trough, which aims to improve the problems of simple wire harness fixing structure, insufficient locking force, easy loosening under vibration environment and low reliability in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy profile with integrated cable tray, comprising an aluminum profile body, the aluminum profile body comprising an aluminum substrate and a top cover, the top cover being slidably fitted to the aluminum substrate, and the aluminum substrate having a limiting plate and a fixing mechanism inside; The fixing mechanism includes a wire harness seat, on one side of the top of which a first protrusion is fixedly connected; the fixing mechanism also includes a buckle plate, which is rotatably connected to the other side of the top of the wire harness seat via a first pivot; the fixing mechanism further includes a right-angle buckle, which is rotatably connected to the end of the buckle plate away from the first pivot via a second pivot, and the right-angle buckle is provided with a second protrusion for engaging with the first protrusion; Furthermore, the fixing mechanism also includes a torsion spring, which is sleeved on the second rotating shaft. The two ends of the torsion spring act on the buckle plate and the right-angle buckle respectively to drive the second protrusion to rotate toward the first protrusion. Preferably, the top of the aluminum substrate is provided with a groove, and a protrusion is fixedly connected to the inner side of the top cover, the protrusion being slidably fitted into the groove; Preferably, the inner wall of the aluminum substrate is provided with a slot for inserting the limiting plate; Preferably, the first protrusion has a snap-fit ​​inclined surface facing the second protrusion, and the second protrusion has a locking surface that engages with the snap-fit ​​inclined surface; Preferably, the top of the wire harness seat is provided with an arc-shaped wire harness receiving groove, and the side of the buckle plate facing the wire harness receiving groove has an arc-shaped pressing surface that is adapted to the wire harness receiving groove; Preferably, the first protrusion is integrally formed from the top sidewall of the wire harness seat and extends outward; Preferably, the second protrusion is integrally formed from the inner sidewall of the right-angle buckle and extends toward the first protrusion; Preferably, the aluminum substrate, the top cover, and the limiting plate are all made of aluminum alloy.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem of fixed internal space of wire trough in the prior art and inability to flexibly adjust according to the number and specifications of wire harnesses by opening slots on the inner wall of the aluminum substrate and cooperating with detachable limiting plates.

[0009] 2.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-4This utility model provides an embodiment of an aluminum alloy profile with integrated cable trays, comprising an aluminum profile body 1. The aluminum profile body 1 has a limiting plate 105 for separating space and a fixing mechanism 2 for fixing cable bundles inside. The aluminum profile body 1 is composed of an aluminum substrate 101 and a top cover 102. The top cover 102 is slidably fitted onto the aluminum substrate 101. Specifically, a groove 104 is formed on the top of the aluminum substrate 101, and a protrusion 103 is fixedly connected to the inner side of the top cover 102. 103 can slide along the length direction inside the groove 104, thereby realizing the assembly and separation of the top cover 102 and the aluminum base 101. To ensure the lightweight and strength of the structure, the aluminum base 101, the top cover 102 and the limiting plate 105 are all made of aluminum alloy. In order to realize the flexible division of the internal space of the aluminum base 101, the inner wall of the aluminum base 101 is provided with a slot for inserting the limiting plate 105. The user can insert the limiting plate 105 into the slots located in different positions as needed. The fixing mechanism 2 includes a wire harness base 201, a buckle plate 204, a right-angle buckle 206, and a torsion spring 208. The wire harness base 201 serves as the mounting base for the entire fixing mechanism 2. The top of the wire harness base 201 has an arc-shaped wire harness receiving groove, and on one side of the top of the wire harness base 201, a first protrusion 203 is integrally formed from the top sidewall of the wire harness base 201 and extends outward. The buckle plate 204 is rotatably connected to the other side of the top of the wire harness base 201 via a first rotating shaft 202, and the side of the buckle plate 204 facing the wire harness receiving groove has an arc-shaped pressing surface that matches the curvature of the wire harness receiving groove. The right-angle buckle 206 is connected via a second rotating shaft 208. 05 is rotatably connected to the end of the buckle plate 204 away from the first rotating shaft 202. On the inner side wall of the right-angle buckle 206, a second protrusion 207 is integrally formed and extends toward the first protrusion 203. To achieve a stable snap-fit, the first protrusion 203 has a snap-fit ​​inclined surface facing the second protrusion 207, and the second protrusion 207 has a locking surface that cooperates with the snap-fit ​​inclined surface. The torsion spring 208 is sleeved on the second rotating shaft 205, and the two ends of the torsion spring 208 act on the buckle plate 204 and the right-angle buckle 206 respectively to drive the second protrusion 207 to rotate toward the first protrusion 203, thereby providing a continuous locking force for the right-angle buckle 206. The wire harness seat 201, the buckle plate 204, and the right-angle buckle 206 form a double-pivot lever locking system via the first pivot 202 and the second pivot 205. The buckle plate 204 serves as a connecting lever, with one end rotatably connected to the wire harness seat 201 via the first pivot 202, and the other end rotatably connected to the right-angle buckle 206, which serves as a locking element, via the second pivot 205. To achieve the self-locking function, a torsion spring 208 is sleeved on the second pivot 205, and both ends of the torsion spring 208 act on the buckle plate 204 and the right-angle buckle 206, respectively. This structure allows the torsion spring 208 to continuously apply a torsional load to the right-angle buckle 206, which drives the second protrusion 207 to rotate toward the first protrusion 203, thereby providing preload for maintaining the locking state. Meanwhile, the harness holder 201 and the right-angle buckle 206 are respectively provided with interlocking locking structures. The first protrusion 203 on the harness holder 201 has a snap-fit ​​inclined surface facing the second protrusion 207, and the second protrusion 207 on the right-angle buckle 206 has a locking surface that cooperates with the snap-fit ​​inclined surface. During the closing of the buckle plate 204, the second protrusion 207 slides along the snap-fit ​​inclined surface of the first protrusion 203. After passing the engagement point, under the force of the torsion spring 208, the locking surface of the second protrusion 207 will quickly snap into the rear of the first protrusion 203, forming a stable and reliable mechanical locking state. This snap-fit ​​structure, which includes inclined surface guidance and spring loading, ensures the convenience of the harness fixing operation and the high stability of the fixing state, and can effectively resist accidental loosening under vibration environment. To achieve a convenient and stable connection between the top cover 102 and the aluminum substrate 101, a groove 104 is formed along the length of the top of the aluminum substrate 101. A protrusion 103, which matches the shape and size of the groove 104, is fixedly connected to the inner side of the top cover 102. During assembly, the protrusion 103 can slide within the groove 104. A slot for inserting a limiting plate 105 is formed on the inner wall of the aluminum substrate 101. This slot extends along the vertical direction of the aluminum substrate 101, allowing multiple limiting plates 105 to be inserted to form wiring channels of different widths. The first protrusion 203 has a snap-fit ​​inclined surface facing the second protrusion 207, while the second protrusion 207 has a locking surface that matches it. This structure of the inclined surface and the flat surface is a perfect match. When closed, the second protrusion 207 can easily slide past the first protrusion 203, while providing a reliable vertical locking interface after locking. The top of the wire harness seat 201 is provided with an arc-shaped wire harness receiving groove. Correspondingly, the side of the buckle plate 204 facing the wire harness receiving groove also has an arc-shaped pressing surface. The two arc-shaped surfaces together form a near-circular receiving space. The first protrusion 203 is preferably integrally formed from the top sidewall of the wire harness seat 201 and extends outward. Similarly, the second protrusion 207 is also integrally formed from the inner sidewall of the right-angle buckle 206 and extends towards the first protrusion 203. The integral design improves the overall reliability. The aluminum base 101, the top cover 102 and the limiting plate 105 are all made of aluminum alloy.

[0015] Working principle: When in use, firstly, according to the wiring requirements, insert the limiting plate 105 into the slot opened on the inner wall of the aluminum base 101 to divide the interior of the aluminum base 101 into the wire groove of the required size. Then, place the fixing mechanism 2 in the wire groove and arrange the wire harness in the arc-shaped wire harness receiving groove at the top of the wire harness seat 201. When it is necessary to fix the wire harness, press down on the buckle plate 204. The buckle plate 204 rotates downward around the first pivot 202. The arc-shaped pressing surface of the buckle plate 204 gradually approaches and presses the wire harness. During this process, the right-angle buckle 206 connected to the other end of the buckle plate 204 moves toward the first protrusion 203 of the wire harness seat 201. The locking surface of the second protrusion 207 on the right-angle buckle 206 contacts and slides along the snapping slope of the first protrusion 203. This sliding process will cause the right-angle buckle 206 to rotate slightly outward around the second pivot 205, thereby overcoming the preload of the torsion spring 208. When the second protrusion 207 completely passes the first protrusion 203, the torsional force previously stored in the torsion spring 208 is released instantaneously. The two ends of the torsion spring 208 act on the buckle plate 204 and the right-angle buckle 206 respectively, driving the second protrusion 207 to rotate toward the first protrusion 203, causing the right-angle buckle 206 to quickly rotate inward. Finally, the locking surface of the second protrusion 207 is firmly engaged behind the first protrusion 203, forming a stable self-locking state and firmly fixing the wire harness. After all the wire harnesses are fixed by the fixing mechanism 2, the protrusion 103 of the top cover 102 is aligned with the groove 104 of the aluminum substrate 101 and slid in along the length of the aluminum substrate 101, finally completely covering the opening of the aluminum substrate 101, forming a neat and closed wire trough structure.
