Description

Technical Field

[0001] This utility model relates to a cable tray and a cabinet, and more specifically, it relates to a cable tray structure and a cabinet. Background Technology

[0002] Cable trays, also known as wiring ducts, wiring trunking, or cable management ducts, are used to neatly organize power cords, data cables, and other wires. They are often used in electrical cabinets, and common types include environmentally friendly PVC toothed cable trays.

[0003] For example, in the prior art, Chinese patent document with application number CN201811064066.1, whose patent title is "Multi-purpose Toothed Opening Line Groove," etc. Figure 1 As shown in the image, cover plate 2 is fastened onto the slot teeth. When routing cables in an electrical cabinet, a common problem is that when the cables converge at the main socket, they are squeezed and pressed against the cable slot of the main socket. The main reason for this is that when wiring, in order to ensure that the cables are long enough and to facilitate the electrician's connection of the cables to the main socket, it is necessary to reserve enough spare cables.

[0004] After the wiring at the main socket is completed, the excess wire will be squeezed into the wire groove. Then, the wire groove is covered by a cover plate to conceal the wire. However, due to the excessive excess wire at the main socket, the squeezed wire often pushes open the cover plate, resulting in the wires at the main socket being messy and exposed. Utility Model Content

[0005] The primary objective of this invention is to provide a trough structure that uses a threaded locking method to fix the trough and the cover plate, thereby reducing the occurrence of excessive wires squeezing out of the cover plate inside the trough.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A cable tray structure includes a tray body with grooved teeth on both sides. A cover plate is engaged with the grooved teeth and slides along the length of the tray body. The structure also includes: a bolt threaded to the bottom of the tray body; a through hole in the cover plate for the bolt head to pass through; and a through hole in the cover plate communicating with the through hole. When the cover plate is engaged with the tray body, the bolt head slides into the through hole. When the cover plate slides in the tray body, the threaded portion of the bolt moves along the through hole. When the bolt is tightened, the bolt head abuts against the upper surface of the cover plate.

[0008] Preferably, the upper surface of the cover plate is provided with reinforcing ribs for pressing the caps of bolts together.

[0009] Preferably, the reinforcing ribs are arranged on both sides of the hole.

[0010] Preferably, the reinforcing ribs include long ribs and short ribs, with the short ribs perpendicular to the long ribs and the long ribs located on both sides of the hole.

[0011] Preferably, the bottom of the groove is provided with a threaded part, and the threaded part is connected to the bolt thread.

[0012] Preferably, the threaded portion includes a threaded hole and a cavity, and the bolt is connected to the threaded hole; the bolt is fixed with a stop block located in the cavity to prevent the bolt from disengaging from the threaded portion.

[0013] Preferably, the bottom of the trough has an opening located at the bottom of the cavity to allow the stop block to extend out of the trough.

[0014] The second objective of this utility model is to provide a cabinet in which the groove and the cover are fixed by a threaded locking method, thereby reducing the occurrence of excessive squeezing of the cover by the wires inside the groove.

[0015] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0016] A cabinet includes a shell, the shell being equipped with electrical components and a main socket, and the shell having a cable tray structure inside.

[0017] In summary, this utility model has at least one of the following beneficial effects:

[0018] After the user inserts the cable into the groove, they press the cover plate to press the cable together, so that the cover plate is fastened to the groove. Then, the cover plate is slid and the bolts are tightened. The outer wall of the cover plate and the head of the bolts abut against each other, thus forming a barrier. The cover plate is difficult to detach from the groove, the pressed cable is difficult to push open the cover plate, and the cable is also difficult to be scattered outside the groove.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1, a grooved structure, referring to Figure 1 It includes a trough 11, with grooves 12 on both sides of the trough 11. The grooves 12 are fastened with a cover plate 13. Both the trough 11 and the grooves 12 are made of plastic. There is a gap between adjacent grooves 12 to facilitate the line to extend out of the gap individually.

[0036] The slot tooth 12 is elastic and its top can deform elastically. The two sides of the cover plate 13 and the top of the slot tooth 12 are fastened together, and the fasteners on the top of the slot tooth 12 are arranged at equal intervals to form a slide rail. Therefore, after the cover plate 13 is fastened to the slot tooth 12, the cover plate 13 can slide along the direction of the formed slide rail, that is, the length direction of the groove 11. The fastening and sliding relationship between the cover plate 13 and the slot tooth 12 is the existing technology of wire groove, and will not be described in detail here.

[0037] A hole is made at the bottom of the groove 11, and the hole is fixed to the cabinet with screws.

[0038] Reference Figures 1-3 The bottom of the groove 11 is provided with a threaded part 5, which is a threaded post with internal threads. The threaded part 5 is threaded to the bolt 2.

[0039] Reference Figures 4-5 The head 21 of bolt 2 extends out of cover plate 13, and the head 21 is located above cover plate 13;

[0040] After the cover plate 13 and the groove 11 are fastened together, tighten the bolt 2 so that the head 21 of the bolt 2 presses against the cover plate 13, thereby making the cover plate 13 stably pressed against the groove 11 and reducing the occurrence of the line body opening the cover plate 13.

[0041] Reference Figures 2-3 The cover plate 13 has a through hole 31 and a sliding hole 32. The through hole 31 is a circular hole. The through hole 31 is larger than the cap 21 of the cover plate 13, so the cap 21 can freely enter and exit the through hole 31.

[0042] The row hole 32 is a strip-shaped hole, and the row hole 32 is arranged on both sides of the through hole 31. The width of the row hole 32 is greater than the diameter of the threaded portion 5 of the bolt 2, and the width of the row hole 32 is less than the diameter of the head portion 21 of the bolt 2. Therefore, the threaded portion 5 of the bolt 2 can move smoothly along the row hole 32.

[0043] When the cap 21 of bolt 2 presses against the cover plate 13, the cap 21 will press against the edge of the hole 32 to achieve the pressing action.

[0044] To enhance the structural strength of the pressing position of the cover plate 13, reinforcing ribs 4 are provided. The reinforcing ribs 4 include long ribs 41 and short ribs 42, with the short ribs 42 perpendicular to the long ribs 41. The long ribs 41 are located on both sides of the passage 32. The reinforcing ribs 4 are arranged on both sides of the passage 32.

[0045] Reference Figure 5 When bolt 2 is tightened, the head 21 of bolt 2 will press against the short rib 42. The setting of the reinforcing rib 4 makes the material at the pressing position thicker, which is less prone to cracking, and the reinforcing rib 4 increases the overall structural strength near the pressing position.

[0046] Furthermore, friction stripes are provided on the surface of the short rib 42, and the bolt 2 is pressed into the friction stripes and is not easy to loosen.

[0047] Operating principle:

[0048] 1. First, lay the wiring inside the cable tray;

[0049] 2. Then cover the groove 11 with the cover plate 13. At this time, the cap 21 extends out of the cover plate 13 through the through hole 31, as shown. Figure 3 ;

[0050] 3. Then slide the cover plate 13, and the cover plate 13 and the groove 11 will close together accordingly, as shown. Figure 4 ;

[0051] 4. Then tighten bolt 2 so that bolt 2 presses into the groove 11 of cover plate 13, as shown. Figure 5 .

[0052] The advantages of this embodiment include one of the following:

[0053] (1) The purpose of using bolt 2 to be threaded into the groove 11 is that if the groove 11 is filled with wire and then bolt 2 is inserted into the bottom of the groove 11 through the cover plate 13, the bottom of bolt 2 and the threaded part 5 may be pressed together or even broken during the process of bolt 2 being inserted. At this time, it is difficult for the staff to effectively strip the wire from the groove 11. The setting of bolt 2 installed in the groove 11 can obviously effectively reduce the occurrence of the wire being broken by the bottom of bolt 2.

[0054] (2) The purpose of using a larger perforation 31 and a sliding hole 32 is that the perforation 31 of the cover plate 13 is larger, and the bolt 2 can freely enter and exit the cover plate 13 through the perforation 31. Therefore, the cover plate 13 can be separated from the bolt 2 cap 21 first, so that the cover plate 13 can be completely separated from the tank 11, which is convenient for employees to arrange the line in the tank 11.

[0055] Example 2, a grooved structure, differs from Example 1 in that, referring to... Figure 6 The threaded part 5 includes a threaded hole 51 and a cavity 52. ​​The threaded part 5 is a columnar structure. The threaded part 5 has a threaded hole 51 at its end, which is used for bolt 2 connection.

[0056] The threaded part 5 has a cavity 52 inside. The cavity 52 has a large space. The bottom of the bolt 2 is fixed with a stop 22. The stop 22 is located inside the cavity 52 and can move up and down inside the cavity 52.

[0057] The threaded hole 51 of the threaded part 5 is provided with a stop edge. The stop block 22 is a round disc block. The stop block 22 does not restrict the circumferential rotation of the bolt 2. The purpose of the stop block 22 is to limit the bolt 2 in the axial direction. Specifically, when the stop block 22 moves to the threaded hole 51, the stop block 22 and the stop edge of the threaded hole 51 are in contact, which can prevent the bolt 2 from separating from the threaded part 5.

[0058] An opening 53 is provided at the bottom of the groove 11, and the opening 53 is located at the bottom of the cavity 52 so that the stop block 22 can extend out of the groove 11;

[0059] The design of the groove 11 is to facilitate the installation of the stop block 22 and the bolt 2. Since the groove 11 and the cover plate 13 are injection molded, the bolt 2 and the stop block 22 are later assembly parts. In order to install the two on the groove 11, the stop block 22 can enter the cavity 52 through the opening 53, and the bolt 2 and the stop block 22 can be glued together.

[0060] The purpose of restricting the bolt 2 from detaching from the trench 11 is to prevent, as far as possible, the bolt 2 from detaching from the trench 11 due to the employee's mistaken operation of rotating it in the opposite direction after the cable is laid in the trench 11.

[0061] Example 3, a cabinet, referring to Figure 7 and Figure 8 The cabinet is a control cabinet, which includes a housing 61. The housing 61 has a wire trough structure of embodiment 1 or embodiment 2 installed inside. The trough 11 of the wire trough structure is fixed to the housing 61 by screws. The housing 61 is provided with electrical components 62 and a main socket 63. The wire trough structure at the position of the main socket 63 is tightened with bolts 2 to reduce the dense wires of the main socket 63 from opening the cover plate 13.
