Description

Technical Field

[0001] This utility model relates to the field of cable trays, and in particular to a convenient cable tray. Background Technology

[0002] Cable trays are metal structural frames used in wiring projects, primarily for supporting and protecting wires, cables, and other wiring. These trays are typically made of metal materials (such as steel or aluminum), possessing good mechanical strength and corrosion resistance. They can be installed on walls, ceilings, or columns, facilitating wiring management and maintenance.

[0003] During the installation of cable trays, there are three types of connections: straight-line connections along the length, angle connections along the length, and connections where one end is connected to a side along the length. The general procedure involves fixing the cable tray with hangers, then cutting or filling the connection point to achieve either a straight-line connection or a connection where one end is connected to a side along the length. Angled connections require additional corner pipes and hanger structures during fixing. All of these connection methods lack convenience, flexibility, and the ability to guarantee connection strength, and the flatness at the connection point is often insufficient. Utility Model Content

[0004] The main purpose of this utility model is to provide a convenient cable tray, which aims to solve the problems of insufficient convenience, lack of flexibility, difficulty in ensuring connection strength, and insufficient flatness at the connection position of the cable tray connection method.

[0005] To achieve the above objectives, this utility model provides a convenient cable tray, comprising:

[0006] A straight cable tray includes a U-shaped frame and a cover plate. The U-shaped frame includes a base plate and side plates connected to both sides of the base plate. The cover plate is snapped between the inner surfaces of the two side plates. The cover plate has two rows of cover ribs arranged side by side in width. Each cover rib group includes cover ribs arrayed in length and protruding outward from the cover plate. The base plate has two rows of bottom ribs arranged side by side in width, corresponding to the cover rib groups in the vertical direction. Each bottom rib group includes bottom ribs arrayed in length and protruding outward from the base plate. Each end of the cover ribs and the bottom ribs has a first hole. The distance between the two first holes in the width direction of the cover plate is the same as the unit length of the cover rib group.

[0007] An angled cable tray is formed at right angles and its two ports correspond to the free ends of the straight cable tray. The surface of the angled cable tray is provided with a plug plate corresponding to the inner surface of the cover rib and the inner surface of the bottom rib. The plug plate is provided with a second hole corresponding to the first hole.

[0008] Multiple T-shaped members are used to connect the straight cable tray to another straight cable tray from the side. Each T-shaped member includes a first plate and a second plate connected to the middle of the first plate. The first plate has a third hole corresponding to the first hole at both ends, and the free end of the second plate has a fourth hole corresponding to the first hole.

[0009] Furthermore, the portable cable tray also includes multiple straight strips, the shape of which matches the inner surface of the cover rib and the inner surface of the bottom rib, and each end of the strip is provided with a fifth hole corresponding to the first hole.

[0010] Furthermore, the material of the strip is selected from either stainless steel or aluminum.

[0011] Furthermore, a protruding plate is provided at the middle of the first plate along its length. When the T-shaped member is combined with the cover rib or the bottom rib, the protruding plate contacts the outer surface of the cover plate or the outer surface of the bottom plate.

[0012] Furthermore, the length of the protruding plate is consistent with the spacing between adjacent bottom protruding ribs.

[0013] Furthermore, the side plate is provided with multiple side recessed structures in an array along its length.

[0014] Furthermore, the side recessed structure and the bottom protruding rib are interposed in the length direction of the U-shaped frame.

[0015] Furthermore, the side recess structure is recessed inward from the outer surface of the cover plate.

[0016] Furthermore, the angle cable tray is fixed to the straight cable tray by means of rivets passing through the first hole and the second hole.

[0017] Furthermore, the materials of the straight cable tray, the corner cable tray, and the T-shaped member are selected from stainless steel and aluminum.

[0018] This utility model provides a convenient cable tray where the cover ribs and bottom ribs serve as reinforcement and a connection base. The cover and bottom ribs have first holes, allowing the insertion plates on the corner cable tray to connect with their inner surfaces, thus improving structural stability. Straight cable trays are connected from the side to another via T-shaped members, which correspond to the cover and bottom ribs. Both the cover and bottom ribs are outwardly protruding, allowing the T-shaped members to fit snugly and securely. The cover plate snaps between the inner surfaces of the two side plates, providing a foundation for the snug connection of one straight cable tray to the side of another. The array of first holes meets certain heat dissipation requirements while providing great flexibility for connections between straight cable trays and between corner and straight cable trays. Furthermore, the processing of the first holes can be performed simultaneously with the stamping of the cover and bottom ribs, significantly reducing processing complexity.

[0032] Reference Figures 1 to 7 In one embodiment of this utility model, a convenient cable tray includes:

[0033] A straight cable tray 100 includes a U-shaped frame 110 and a cover plate 120. The U-shaped frame 110 includes a base plate 111 and side plates 112 connected to both sides of the base plate 111. The cover plate 120 is snapped between the inner surfaces of the two side plates 112. The cover plate 120 has two rows of cover ribs arranged side by side in width. The cover ribs include cover ribs 121 arrayed in length and protruding outward from the cover plate 120. The base plate 111 has two rows of bottom ribs arranged side by side in width, corresponding to the cover ribs in the vertical direction. The bottom ribs include bottom ribs 113 arrayed in length and protruding outward from the base plate 111. The two ends of the cover ribs 121 and the bottom ribs 113 are respectively provided with first holes 101. The distance between the two first holes 101 in the width direction of the cover plate 120 is the same as the unit length of the cover ribs.

[0034] Angle cable tray 200 is right-angled and its two ports correspond to the free ends of straight cable tray 100. An insertion plate 210 corresponding to the inner surface of the cover rib 121 and the inner surface of the bottom rib 113 is provided on the surface of the angle cable tray 200. A second hole 211 corresponding to the first hole 101 is provided on the insertion plate 210.

[0035] Multiple T-shaped members 300 are used to connect the straight cable tray 100 from the side to another straight cable tray 100. Each T-shaped member 300 includes a first plate 310 and a second plate 320 connected to the middle of the first plate 310. The first plate 310 has a third hole 301 corresponding to the first hole 101 at both ends. The free end of the second plate 320 has a fourth hole 302 corresponding to the first hole 101.

[0036] In the existing technology, the various connection methods of pipe cable trays are not convenient enough, not flexible enough, the connection strength is difficult to guarantee, and the flatness at the connection position is not enough.

[0037] In this utility model, the up-and-down direction of the portable cable tray is fixed during use, thus providing directional indication via up-and-down movement. The straight cable tray 100 includes a U-shaped frame 110 and a cover plate 120. The U-shaped frame 110 includes a base plate 111 and side plates 112 connected to both sides of the base plate 111, thus forming a U-shape. The cover plate 120 is snapped between the inner surfaces of the two side plates 112, ensuring that the cover plate 120 does not extend beyond the side plates 112 in the width direction, facilitating the connection between the length end of the straight cable tray 100 and its side surface. The cover plate 120 has two rows of ribs arranged side-by-side in width, each rib including ribs 121 arrayed in length and protruding outwards from the cover plate 120. The ribs 121 act as reinforcing ribs, thereby improving the structural strength of the cover plate 120. The base plate 111 has two rows of bottom ribs arranged side-by-side in the width direction, corresponding vertically to the top ribs. Each bottom rib group comprises bottom ribs 113 arrayed along its length and protruding outwards from the base plate 111. The bottom ribs 113 act as reinforcing ribs, thereby improving the structural strength of the base plate 111 of the U-shaped frame 110. First holes 101 are provided at both ends of the lengths of the top ribs 121 and the bottom ribs 113, providing a foundation for the subsequent fixing of related components.

[0038] The two ports of the angle cable tray 200 correspond to the free ends of the straight cable tray 100. The surface of the angle cable tray 200 is provided with insertion plates 210 corresponding to the inner surfaces of the cover ribs 121 and bottom ribs 113. Four insertion plates 210 are respectively provided on the two ports of the angle cable tray 200; the two insertion plates 210 on the upper surface correspond to the two cover ribs 121, and the two insertion plates 210 on the lower surface correspond to the two bottom ribs 113. The insertion plates 210 are provided with second holes 211 corresponding to the first holes 101. When the angle cable tray 200 needs to connect two straight cable trays 100, the two ports of the angle cable tray 200 are each connected to one straight cable tray 100. During the connection process, the upper surface plug plate 210 is inserted into the inner surface of the cover rib 121, at which point the second hole 211 on the plug plate 210 corresponds to the first hole 101 on the cover rib 121; the lower surface plug plate 210 is inserted into the inner surface of the bottom rib 113, at which point the second hole 211 on the plug plate 210 corresponds to the first hole 101 on the bottom rib 113. The function of the plug plate 210 is to form a connection with the straight cable tray 100. Specifically, after the first hole 101 and the second hole 211 are aligned, the connection is achieved by means of bolts or rivets. After the angle cable tray 200 and the straight cable tray 100 are fixedly connected, a better positional alignment is achieved, making the subsequent installation of the hangers easier and preventing misalignment.

[0039] Multiple T-shaped members 300 are used to connect one straight cable tray 100 to another from the side. Each T-shaped member 300 includes a first plate 310 and a second plate 320 connected to the middle of the first plate 310. The first plate 310 has third holes 301 at both ends corresponding to the first holes 101, and the free end of the second plate 320 has a fourth hole 302 corresponding to the first holes 101. The distance between the two first holes 101 in the width direction of the cover plate 120 is consistent with the unit length of the cover rib assembly (the length of the cover rib 121 plus the spacing). When one straight cable tray 100 is connected to the side of another straight cable tray 100, the two cover ribs 121 on that straight cable tray 100 correspond precisely to the middle of the gap between the cover ribs 121 on the other straight cable tray 100. In this case, the two straight cable trays 100 can be smoothly connected using the T-shaped members 300. The connection between the first hole 101 and the fourth hole 302, and the connection between the first hole 101 and the third hole 301, can be achieved by means of bolts or rivets.

[0040] In summary, the ribs on the top and bottom serve as reinforcement and the basis for connection. The top and bottom ribs 121 and 113 are provided with first holes 101, allowing the insertion plate 210 on the corner cable tray 200 to connect with the inner surfaces of the top and bottom ribs 121 and 113, thus improving structural stability. The straight cable tray 100 is connected from the side to another straight cable tray 100 via a T-shaped member 300. The T-shaped member 300 is positioned corresponding to the top and bottom ribs 121 and 113, and both are outwardly protruding, allowing the T-shaped member 300 to fit snugly and thus form a stable fixation. The cover plate 120 is snapped between the inner surfaces of the two side plates 112, thus providing a basis for the snug connection of one straight cable tray 100 from the side of another straight cable tray 100. The array arrangement of the first hole 101 not only meets certain heat dissipation requirements, but also makes the connection between straight bridges 100 and between the corner bridges 200 and straight bridges 100 very flexible. In particular, the processing of the first hole 101 can be carried out simultaneously during the stamping process of the cover rib 121 and the bottom rib 113, which greatly reduces the complexity of processing.

[0041] In one embodiment, the portable cable tray further includes multiple straight strips, the shape of which matches the inner surface of the cover rib 121 and the inner surface of the bottom rib 113, and each end of the strip is provided with a fifth hole corresponding to the first hole 101.

[0042] In this embodiment, when two straight cable trays 100 are connected in the length direction, a strip-shaped member is used for assistance. Taking the connection on the upper surface as an example, the straight cable tray 100 is cut to expose a suitable cover rib 121 (or it is directly processed into a size that meets the connection conditions during the production process), the strip-shaped member is inserted into the inner surface of the corresponding cover rib 121 of the two straight cable trays 100, and finally the connection is completed by a structure such as bolts or rivets (through the first hole 101 and the fifth hole).

[0043] In one embodiment, the material of the strip is selected from stainless steel and aluminum.

[0044] In this embodiment, stainless steel and aluminum are commonly used engineering materials, which are excellent in terms of processing difficulty, structural strength and weather resistance.

[0045] In one embodiment, a protruding part is provided at the middle of the first plate 310 along its length. When the T-shaped member 300 is combined with the cover rib 121 or the bottom rib group, the protruding part contacts the outer surface of the cover plate 120 or the outer surface of the bottom plate 111.

[0046] In this embodiment, the protruding surface enhances the fixing effect of the T-shaped member 300 and reduces the possibility of deformation during the fixing process.

[0047] In one embodiment, the length of the protruding plate is consistent with the interval between adjacent bottom protruding ribs 113.

[0048] In this embodiment, the length of the protruding plate is also limited, thereby improving the fixing effect of the T-shaped member 300. The length of the protruding plate is also consistent with the interval between adjacent cover ribs 121.

[0049] Reference Figure 1 In one embodiment, the side plate 112 is provided with a plurality of side recessed structures arranged in an array along its length.

[0050] In this embodiment, the reinforcing rib effect is achieved through a side recess structure. Specifically, the direction of the side recess structure can be from the inner wall outward or from the outer wall inward.

[0051] In one embodiment, the side recessed structure and the bottom protruding rib 113 are interposed in the length direction of the U-shaped frame 110.

[0052] In this embodiment, the inter-cavity arrangement complements each other, thereby improving the overall structural strength of the U-shaped frame 110. Otherwise, structural strength defects are likely to occur in certain parts.

[0053] In one embodiment, the side recess structure is recessed inward from the outer surface of the cover plate 120.

[0054] In this embodiment, the inwardly recessed design ensures that the outer surface of the side plate 112 does not have a protruding structure. Therefore, during the side docking process between the straight cable tray 100 and another straight cable tray 100, the influence of the side recessed structure on the fitting effect does not need to be considered.

[0055] In one embodiment, the angle cable tray 200 is fixed to the straight cable tray 100 by means of rivets passing through the first hole 101 and the second hole 211.

[0056] In this embodiment, due to the presence of the first hole 101 and the second hole 211, the plug plate 210 of the angle cable tray 200 can be connected to the cover rib 121 and the bottom rib 113 of the straight cable tray 100. The connection is achieved by using rivets, which has the advantages of being simple and quick.

[0057] In one embodiment, the straight cable tray 100, the angle cable tray 200, and the T-shaped member 300 are made of either stainless steel or aluminum.

[0058] In this embodiment, stainless steel and aluminum are commonly used engineering materials, which are excellent in terms of processing difficulty, structural strength and weather resistance.

[0059] In summary, the convenient cable tray provided by this utility model, with its cover rib and bottom rib assembly serving as reinforcement and a connection base, provides a convenient cable tray. The cover rib 121 and bottom rib 113 are provided with first holes 101, allowing the insertion plate 210 on the corner cable tray 200 to connect with the inner surfaces of the cover rib 121 and bottom rib 113, thus improving structural stability. The straight cable tray 100 is connected from the side to another straight cable tray 100 via a T-shaped member 300. The T-shaped member 300 is positioned corresponding to the cover rib 121 and bottom rib 113, and both the cover rib 121 and bottom rib 113 are outwardly protruding, allowing the T-shaped member 300 to fit snugly and securely. The cover plate 120 is snapped between the inner surfaces of the two side plates 112, thus providing a foundation for the snug connection of one straight cable tray 100 from the side of another straight cable tray 100. The array arrangement of the first hole 101 not only meets certain heat dissipation requirements, but also makes the connection between straight bridges 100 and between the corner bridges 200 and straight bridges 100 very flexible. In particular, the processing of the first hole 101 can be carried out simultaneously during the stamping process of the cover rib 121 and the bottom rib 113, which greatly reduces the complexity of processing.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
