Description

Technical Field

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

[0002] Metal wire trough is a device used to protect wires. It is often used in small and medium-sized application scenarios where wires need to be sealed and protected, such as commercial buildings, workshops, shopping malls, etc. The difference between metal wire trough and cable tray is that cable tray is used to protect cables and is installed through a combination of brackets and beams and is suspended above the ceiling or fixed to the wall. Metal wire trough is used to protect wires and is usually installed on the wall or ground. It can be surface mounted or buried. In terms of size, metal wire trough is also significantly smaller than cable tray.

[0003] The disadvantages of traditional metal wire troughs are: due to installation requirements, there will be concave-convex structures on the inner wall of the trough or cover (such as installation screws, or the connection between two metal wire troughs is uneven). When pulling the wire, the wire is easily scratched by the concave-convex structure on the inner wall of the trough or cover, causing damage to the wire surface. Utility Model Content

[0004] Based on this, the utility model provides a metal wire trough, in which a guide component for limiting the position of the wire and achieving rolling contact with the wire is arranged in the trough body, thereby reducing the probability of scratching the wire.

[0005] A metal cable duct, comprising:

[0006] Trough body; the trough body is a metal structure; the trough body is used to accommodate the wire;

[0007] A cover connected to the tank body; the cover is a metal structure; the cover covers the tank body; and

[0008] A guide assembly installed on the trough body; the number of guide assemblies is multiple and they are arranged at intervals along the length direction of the trough body; the guide assembly includes: a bracket located in the trough body, and a first transverse roller, a second transverse roller, a first vertical roller, a second vertical roller, and a vertical spring respectively installed on the bracket; the first transverse roller and the second transverse roller are both arranged along the width direction of the trough body; the first transverse roller is located at the bottom of the bracket, and the second transverse roller is slidably arranged along the height direction of the trough body; the first vertical roller and the second vertical roller are both arranged along the height direction of the trough body; the first vertical roller is located on one side of the trough body, and the second vertical roller is located on the other side of the trough body; the vertical spring is located between the second transverse roller and the cover.

[0009] When the above-mentioned metal wire trough is in use, the wire is placed in the trough body and is guided and limited by the guide assembly. Among them, the first horizontal roller, the second horizontal roller, the first vertical roller, and the second vertical roller in the guide assembly form a frame structure around the outer periphery of the wire to prevent the wire from directly contacting the inner wall of the trough body or the cover. When the wire contacts any roller and relative friction occurs, the corresponding roller will roll by itself to adjust its posture, reducing the probability of scratching and damaging the wire. At the same time, after the cover is connected to the trough body, the cover will compress the vertical spring, thereby generating downward pressure on the second horizontal roller, and the second horizontal roller is used to press the guide downward, so that the wire moves more regularly and the probability of scratching and damaging is reduced. Through the above design, a guide assembly for limiting the wire and achieving rolling contact with the wire is set in the trough body to reduce the probability of scratching the wire.

[0010] In one embodiment, the tank body and the cover are detachably connected by screws, which can realize quick installation or removal between the tank body and the cover, with high installation and removal efficiency and strong connection stability.

[0011] In one embodiment, the tops of both sides of the slot body are provided with inwardly extending transverse folds; the transverse folds are in contact with the top of the bracket; the transverse folds are provided with avoidance openings; the avoidance openings are used for the second transverse roller and the vertical spring to pass through. The transverse folds can limit the bracket in the height direction of the slot body, thereby improving the stability of the guide assembly installation. At the same time, after the avoidance openings are provided, the second transverse roller and the vertical spring can be placed into the slot body from the avoidance openings in sequence after the wire is placed, thereby reducing the difficulty of installation.

[0012] In one embodiment, the bracket and the tank body are detachably connected by screws. The screws can realize quick installation or removal between the bracket and the tank body, with high efficiency and strong connection stability.

[0013] In one embodiment, the bracket is provided with a plurality of first columns and a plurality of second columns; the first columns and the second columns are both arranged along the height direction of the trough; the first transverse roller shaft and the second transverse roller shaft are both slidably arranged between the two first columns; the first vertical roller shaft is sleeved on one of the second columns; and the second vertical roller shaft is sleeved on the other second column. The roller shaft is installed by using the columns, which has a simple structure and strong reliability.

[0014] In one embodiment, the first transverse roller, the second transverse roller, the first vertical roller, and the second vertical roller are all roller structures with elasticity. The elastic roller structure can reduce the probability of scratching the wire.

[0015] In one embodiment, the surface of the tank body and the cover are both provided with a zinc coating, which is used to prevent rust.

[0016] In one embodiment, the surface of the tank body and the cover are both covered with a plastic film, which is used for rust prevention and insulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figures 1 to 8 As shown, it is a metal wire duct 100 according to an embodiment of the present invention.

[0037] like Figure 1 system Figure 4 As shown, the metal wire trough 100 comprises: a trough body 10, a cover 20 connected to the trough body 10, and a guide assembly 30 installed on the trough body 10. The trough body 10 is used to accommodate the wires and is sealed by the cover 20 (excluding the two ends in the length direction). The guide assembly 30 is used to limit the wires placed in the trough body 10 and achieve rolling contact, so as to reduce the probability of the wires being scratched and damaged.

[0038] It should be noted that, generally, a plurality of wires are placed in the metal wire duct 100 at the same time, and therefore, the metal wire duct 100 of the present solution can also be understood as being used to protect the wire harness.

[0039] Below, combined Figures 1 to 8 , the above-mentioned metal wire duct 100 is further explained.

[0040] like Figure 4 As shown, the slot body 10 is a metal structure, and the slot body 10 is used to accommodate the wires.

[0041] like Figure 1 and Figure 4As shown, the cover 20 is a metal structure, and the cover 20 covers the tank body 10, thereby forming a cavity for protecting the wire. For example, in this embodiment, the tank body 10 and the cover 20 can be made of aluminum alloy, stainless steel, or other types of metal plates.

[0042] In this solution, there are many specific connection methods between the tank body 10 and the cover 20, such as sliding connection, snap connection, screw connection, etc. Figure 1 As shown, in this embodiment, the tank body 10 and the cover 20 are detachably connected by screws. The tank body 10 and the cover 20 can be quickly installed or disassembled by screws, with high efficiency and strong connection stability.

[0043] In addition, considering the wide variety of usage scenarios of the metal wire duct 100, which may need to face a very harsh working environment, targeted improvements can also be made to improve its anti-rust performance.

[0044] For example, the surface of the tank body 10 and the cover 20 are both provided with a zinc coating, which is used to prevent rust.

[0045] For another example, the surfaces of the tank body 10 and the cover 20 are both covered with a plastic film. The plastic film is used to prevent rust and also to provide insulation.

[0046] like Figure 5 As shown, the number of guide assemblies 30 is multiple and is arranged at intervals along the length direction of the slot body 10. For example, in this embodiment, the number of guide assemblies 30 is two and is arranged close to the ports of the slot body 10 respectively.

[0047] Combination Figure 6 and Figure 7 As shown, the guide assembly 30 includes: a bracket 31 located in the tank 10, and a first transverse roller 32, a second transverse roller 32, a first vertical roller 33, a second vertical roller 34, and a vertical spring 35 respectively mounted on the bracket 31. Figure 6 As shown, the first transverse roller 32 and the second transverse roller 32 are both arranged along the width direction of the trough body 10, and the first transverse roller is located at the bottom of the bracket 31, and the second transverse roller 32 is slidably arranged along the height direction of the trough body 10. Figure 6 As shown, the first vertical roller 33 and the second vertical roller 34 are both arranged along the height direction of the tank body 10. The first vertical roller 33 is located on one side of the tank body 10, and the second vertical roller 34 is located on the other side of the tank body 10. Figure 7 As shown, the vertical spring 35 is located between the second transverse roller 32 and the cover 20 (the vertical spring 35 in the figure is in a compressed state, and before the cover 20 is installed, the vertical spring 35 is in a naturally extended state).

[0048] In order to improve the installation stability of the guide assembly 30 and reduce the installation difficulty, as shown in FIG. Figure 5 As shown, in this embodiment, the tops of both sides of the trough body 10 are provided with inwardly extending transverse folds 11. The transverse folds 11 abut against the top of the bracket 31, and the transverse folds 11 are provided with avoidance openings 111. The avoidance openings 111 are used for the second transverse roller 32 and the vertical spring 35 to pass through. The transverse folds 11 can limit the bracket 31 in the height direction of the trough body 10, thereby improving the stability of the installation of the guide assembly 30. At the same time, after the avoidance openings 111 are provided, the second transverse roller 32 and the vertical spring 35 can be placed into the trough body 10 from the avoidance openings 111 in sequence after the wire is placed, thereby reducing the difficulty of installation.

[0049] It should be noted that, in some other embodiments, the avoidance opening 111 may also be configured as an opening structure into which the entire guide assembly 30 can be placed along the height direction of the slot body 10 . Under this design, the avoidance opening 111 has no limiting effect on the bracket 31 .

[0050] In addition, in this embodiment, there are many ways to connect the bracket 31 and the tank body 10, such as welding, snap connection, screw connection, etc. Figure 5 As shown, in this embodiment, the bracket 31 and the tank body 10 are detachably connected by screws. The bracket 31 and the tank body 10 can be quickly installed or disassembled by screws, with high efficiency and strong connection stability.

[0051] like Figures 6 to 8 As shown, in the present embodiment, the bracket 31 is provided with a plurality of first columns 311 and a plurality of second columns 312. The first columns 311 and the second columns 312 are both arranged along the height direction of the trough body 10. The first transverse roller 32 and the second transverse roller 32 are both slidably arranged between the two first columns 311. The first vertical roller 33 is sleeved on one of the second columns 312. The second vertical roller 34 is sleeved on the other second column 312. The installation of the rollers is realized by using columns, and the structure is simple and the reliability is strong. For example, in the present embodiment, the first column 311 and the second column 312 are both cylinders, and the first transverse roller 32, the second transverse roller 32, the first vertical roller 33, and the second vertical roller 34 are respectively provided with sleeve portions (in the present embodiment, each sleeve portion is a circular arc groove structure of not less than 180°).

[0052] In order to better protect the wire and reduce the probability of scratching the surface of the wire, in this embodiment, the first horizontal roller 32, the second horizontal roller 32, the first vertical roller 33, and the second vertical roller 34 are all elastic roller structures. The elastic roller structure can reduce the probability of scratching the wire. For example, the shaft body of each roller is a metal shaft, and a cylindrical silicone sleeve is sleeved on the metal shaft.

[0053] Brief description of working principle:

[0054] Combination Figure 3 and Figure 5 As shown, when in use, the wire is placed in the trough body 10 and is guided and limited by the guide assembly 30. Among them, the first horizontal roller 32, the second horizontal roller 32, the first vertical roller 33, and the second vertical roller 34 in the guide assembly 30 form a frame structure around the outer periphery of the wire to prevent the wire from directly contacting the inner wall of the trough body 10 or the cover 20. When the wire contacts any roller and relative friction occurs, the corresponding roller will roll by itself to adjust its posture, reducing the probability of scratching and damaging the wire. At the same time, after the cover 20 is connected to the trough body 10, the cover 20 will compress the vertical spring 35, thereby generating downward pressure on the second horizontal roller 32, and use the second horizontal roller 32 to press the guide downward, so that the wire runs more regularly and the probability of scratching and damaging is reduced.

[0055] The metal wire trough 100 is provided with a guide assembly 30 for limiting the position of the wire and achieving rolling contact with the wire in the trough body 10, thereby reducing the probability of scratching the wire.

[0056] The technical features of the above embodiments may 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.

[0057] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
