Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge design, in particular to a cable bridge. Background Art

[0002] A cable tray is a device used to protect cables and is commonly used in large offices, industrial workshops, bridges, and public places. Multiple cable trays are connected in series to form a channel for cable routing. Multiple cable trays can also be set up in parallel to route cables according to different types of cables, such as high-voltage and low-voltage cables.

[0003] Since cable trays have a wide variety of application scenarios, the specific installation method of cable trays also needs to be adjusted according to the corresponding application scenarios. For example, common installation methods include hoisting (suspended installation through steel wires or hangers), bridge mounting (installed on the ground or on an object through a bracket), and wall mounting (vertically or obliquely installed close to the wall). Traditional cable trays need to be configured with different support components according to different application scenarios for users to choose from. The drawbacks are: first, manufacturers have to develop a wide variety of accessories, which results in high mold costs and low production efficiency; second, in actual application scenarios, there may be multiple installation methods coexisting. Users need to carefully plan the installation lines in advance and configure the corresponding support components (they need to communicate with the manufacturer several times to determine which support components to use). The preparation work is cumbersome and the operation is difficult. Utility Model Content

[0004] Based on this, the present invention provides a cable tray that utilizes support components with multiple deformation functions to meet the needs of different installation methods, reducing the number of accessory types required, thereby reducing manufacturers' mold opening costs and improving production efficiency. At the same time, it simplifies the user's preliminary installation work planning and reduces the difficulty of the operation.

[0005] A cable tray, comprising:

[0006] The trough body is provided with a wire groove arranged along the length direction;

[0007] A cover plate connected to the trough body; the cover plate covers the wire trough along the length direction of the trough body; and

[0008] A support assembly detachably connected to the trough body; the support assembly comprises: a first swing arm, a crossbar, and a second swing arm hinged in sequence; defining the length of the first swing arm as a, the length of the second swing arm as b, and the length of the crossbar as c, then a=b, a+b>c, and a 2 +b 2 =c 2; The free end of the first rocker arm and the free end of the second rocker arm are both provided with hinge holes; the first rocker arm, the cross bar, and the second rocker arm are all provided with connecting holes; the connecting holes are used to connect the trough body or the cover plate.

[0009] The above-mentioned cable tray is provided with a support assembly that can realize various morphological changes. The first swing arm, the horizontal bar, and the second swing arm of the support assembly are hinged in sequence, and the three meet the side length requirements of an isosceles triangle. Therefore, the first swing arm and the second swing arm can be flipped to adjust the relative angle with the horizontal bar, thereby changing to a straight line, a concave shape, and an isosceles triangle. When hoisting is required, the support assembly can be adjusted to a straight line or a concave shape to support the trough body; when bridge installation is required, the support assembly can be adjusted to an isosceles triangle to support the trough body; when it needs to be against a wall, the installation assembly can be adjusted to a concave shape to laterally clamp and fix the trough body. Through the above design, a support assembly with multiple deformation functions is utilized to meet the needs of different installation methods, reducing the type of accessories required, and achieving the purpose of reducing the manufacturer's mold opening cost and improving production efficiency. At the same time, it simplifies the user's preliminary work planning for installation work and reduces the difficulty of the operation.

[0010] In one embodiment, the trough body has an L-shaped first bend located at the notch of the cable trough; the cover plate has a second bend corresponding to the first bend; the first and second bends form a sealing structure at the connection between the trough body and the cover plate. The sealing structure formed by the first and second bends improves the sealing between the trough body and the cover plate, thereby enhancing the protection of the cable.

[0011] In one embodiment, the tank body and the cover plate are detachably connected, which is beneficial for improving the efficiency of assembly and disassembly.

[0012] In one embodiment, the connection method between the trough body and the cover plate includes: sliding connection, snap connection, screw connection, and magnetic connection.

[0013] In one embodiment, the support assembly further comprises: a plurality of articulated shafts and a plurality of nuts; each end of the articulated shafts is provided with external threads that mate with the nuts; the first swing arm, the horizontal bar, and the second swing arm are sequentially articulated via the articulated shafts and the nuts; and the articulated shafts mate with articulated holes on the free ends of the first and second swing arms. The combination of the articulated shafts and nuts not only enables articulation between the first swing arm, the horizontal bar, and the second swing arm, but also allows the support assembly to be locked in position by adjusting the feed depth of the nuts, resulting in a simple structure and flexible and convenient use.

[0014] In one embodiment, clearing zones are provided at both ends of the first swing link, both ends of the horizontal bar, and both ends of the second swing link. These clearing zones enable the first and second swing links to flip clockwise and counterclockwise relative to the horizontal bar. The provision of these clearing zones enhances the swinging flexibility of the first and second swing links, facilitating the support assembly's multi-configuration transformations.

[0015] In one embodiment, the surfaces of the first swing arm, the horizontal bar, and the second swing arm are all provided with anti-slip grooves. The anti-slip grooves are used to increase the friction coefficient between the first swing arm, the horizontal bar, and the second swing arm and the slot body and the cover plate, thereby improving the stability of the installation.

[0016] In one embodiment, the tank body, the cover plate, the first swing arm, the cross bar, and the second swing arm are all metal parts and are covered with a plastic layer. The plastic layer can protect the surface of the metal parts from rust, which is beneficial to extending the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figures 1 to 12 As shown, it is a cable tray 100 according to an embodiment of the present invention.

[0041] like Figures 1 to 3 As shown, the cable tray 100 includes a trough 10, a cover plate 20 connected to the trough 10, and a support assembly 30 detachably connected to the trough 10. The trough 10 is used to carry cables, and the cover plate 20 is used to form a relatively sealed protective space with the trough 10. The support assembly 30 is used to support the trough 10.

[0042] Below, combined Figures 1 to 12 As shown, the above-mentioned cable tray 100 is further explained.

[0043] like Figure 3 As shown, the trough body 10 is provided with a wire groove 11 arranged along the length direction. In this embodiment, the trough body 10 is a U-shaped structure formed by bending a whole piece of metal plate.

[0044] Combine Figure 1 and Figure 3 As shown, the cover plate 20 covers the wire trough 11 along the length direction of the trough body 10. In this embodiment, the cover plate 20 is formed by bending a positive metal plate.

[0045] In order to improve the sealing performance of the connection between the tank body 10 and the cover plate 20, further improvements can be made. Figure 1 As shown, in this embodiment, the trough body 10 has an L-shaped first bend 12 located at the notch of the cable trough 11. The cover plate 20 has a second bend 21 corresponding to the first bend 12. The first bend 12 and the second bend 21 form a sealing structure at the connection between the trough body 10 and the cover plate 20. The sealing structure formed by the first bend 12 and the second bend 21 improves the sealing between the trough body 10 and the cover plate 20, thereby enhancing the protection of the cable.

[0046] In addition, in order to facilitate assembly and disassembly, improve the assembly efficiency of the equipment and reduce the difficulty of subsequent maintenance, in this embodiment, the tank body 10 and the cover plate 20 are preferably detachably connected. The detachable connection method is conducive to improving assembly and disassembly efficiency.

[0047] For example, in this embodiment, the connection between the tank body 10 and the cover plate 20 is a sliding connection. Figure 1 As shown, the cover plate 20 is slidably connected to the trough body 10 along the length direction of the trough body 10. In other embodiments, the trough body 10 and the cover plate 20 may also be connected by snapping, screwing, or magnetic attraction.

[0048] like Figure 4 As shown, the support assembly 30 includes: a first swing rod 31, a cross bar 32, and a second swing rod 33, which are hinged in sequence. The length of the first swing rod 31 is defined as a, the length of the second swing rod 33 is defined as b, and the length of the cross bar 32 is defined as c. Then a=b, a+b>c, and a 2 +b 2 =c 2That is, in this embodiment, the support assembly 30 formed by the first swing arm 31, the horizontal bar 32, and the second swing arm 33 meets the structural requirements of an isosceles triangle. The free ends of the first swing arm 31 and the second swing arm 33 are each provided with a hinge hole. The first swing arm 31, the horizontal bar 32, and the second swing arm 33 are each provided with a connection hole. The connection hole is used to connect to the trough body 10 or the cover plate 20 (both the trough body 10 and the cover plate 20 are pre-set with matching holes, and can be connected in series using screws).

[0049] In order to realize the sequential hinge connection between the first swing rod 31, the cross bar 32, and the second swing rod 33. Figure 4 As shown, in this embodiment, the support assembly 30 may further include: a plurality of articulated shafts 34 and a plurality of nuts 35. Both ends of the articulated shafts 34 are provided with external threads that match the nuts 35. The first rocker arm 31, the horizontal bar 32, and the second rocker arm 33 are articulated in sequence through the articulated shafts 34 and the nuts 35, and the articulated shafts 34 match the articulated holes on the free ends of the first rocker arm 31 and the second rocker arm 33. The combination of the articulated shafts 34 and the nuts 35 not only realizes the articulation between the first rocker arm 31, the horizontal bar 32, and the second rocker arm 33, but also can lock the posture of the support assembly 30 by adjusting the feed depth of the nuts 35. It has a simple structure and is flexible and convenient to use.

[0050] See also Figure 5 As shown, in this embodiment, both ends of the first swing link 31, both ends of the crossbar 32, and both ends of the second swing link 33 may be provided with a clearance zone 36. The clearance zone 36 is used to enable the first and second swing links 31, 33 to flip clockwise and counterclockwise relative to the crossbar 32. The provision of the clearance zone 36 can improve the swing flexibility of the first and second swing links 31, 33, and facilitate the support assembly 30 to achieve multiple configuration changes.

[0051] To ensure a more stable and reliable connection between the support assembly 30, the trough body 10, and the cover plate 20, in other embodiments, the surfaces of the first swing arm 31, the horizontal bar 32, and the second swing arm 33 may be provided with anti-slip grooves. The anti-slip grooves are used to increase the coefficient of friction between the first swing arm 31, the horizontal bar 32, and the second swing arm 33 and the trough body 10 and the cover plate 20, thereby improving installation stability.

[0052] Furthermore, considering that the cable tray 100 is often used in harsh environments, the trough 10, cover 20, first swing arm 31, crossbar 32, and second swing arm 33 are all metal components and are coated with a plastic layer. The plastic layer can protect the surface of the metal components from rust, thereby extending the service life of the equipment.

[0053] Brief description of working principle:

[0054] In this solution, a support assembly 30 is provided that can achieve various morphological changes. The first rocker arm 31, the horizontal bar 32, and the second rocker arm 33 of the support assembly 30 are hinged in sequence, and the three meet the side length requirements of an isosceles triangle. Therefore, the first rocker arm 31 and the second rocker arm 33 can be flipped to adjust the relative angle with the horizontal bar 32, thereby transforming into a straight line shape, a concave shape, and an isosceles triangle shape.

[0055] When hoisting is required, the support assembly 30 can be adjusted to a straight or concave shape to support the tank body 10. For example, Figure 5 and Figure 6 As shown, the support assembly 30 is adjusted to a straight line. When in use, the horizontal bar 32 is attached to the bottom of the trough 10, the hinged ends of the first swing arm 31 and the second swing arm 33 are locked, and the free ends of the first swing arm 31 and the second swing arm 33 are connected to steel wires or suspension rods. Figures 2 to 4 As shown, during use, the horizontal bar 32 is adjusted to a horizontal position, while the first and second swing arms 31, 33 are vertically upward, thereby forming a concave-shaped bracket structure with the opening facing upward. The free ends of the first and second swing arms 31, 33 are respectively connected to steel wires or suspension rods. Compared to the straight-line structure, this structure adds the function of lateral positioning on both sides of the trough body 10. In addition, the support assembly 30 can be adjusted to an inverted concave-shaped position and connected to the trough body 10 in an inverted manner. Then, the middle of the horizontal bar 32 is connected to the suspension rod or steel wire to achieve hoisting.

[0056] When a bridge is required, the support assembly 30 can be adjusted to an isosceles triangle to support the tank body 10. For example, Figures 7 to 9 As shown, when in use, the free end of the first rocker arm 31 and the free end of the second rocker arm 33 are connected together to form an isosceles right triangle structure. At this time, any one of the first rocker arm 31, the horizontal bar 32, and the second rocker arm 33 can be selected to be connected to the bottom of the trough body 10 (in this embodiment, the connection between the second rocker arm 33 and the trough body 10 is shown as an example).

[0057] When it is necessary to lean against a wall, the mounting assembly can be adjusted to a concave shape to laterally clamp and fix the tank body 10. For example, Figures 10 to 12 As shown, when in use, the first swing arm 31 and the second swing arm 33 are adjusted to a horizontal posture, and the cross bar 32 is vertically upward, thereby forming a concave bracket structure with an open side, and the free ends of the first swing arm 31 and the second swing arm 33 are locked together with the wall.

[0058] The cable tray 100 utilizes a support assembly 30 with multiple deformable functions to accommodate various installation requirements, reducing the number of required accessories, thereby lowering mold costs and improving production efficiency. Furthermore, it simplifies the user's initial installation planning and reduces the complexity of the installation.

[0059] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
