Detailed Description
An adjustable spacer for a cable tray according to the present utility model will be described in detail with reference to the accompanying drawings and examples.
The utility model relates to an adjustable spacer for a cable trough box, which is made of metal to meet the electromagnetic interference resistance requirement, and comprises: the device comprises a top plate 1, a vertical plate 2, a plurality of bases 3 and a plurality of fixing bolts 5; the lower surface of the top plate 1 is provided with a mortise A, and the upper surface of the base 3 is provided with a mortise B; the bottom of the vertical plate 2 is joggled with the upper surface of the base 3 through a joggle groove B; the top of the vertical plate 2 is joggled with the lower surface of the top plate 1 through a joggle groove A; each base 3 is provided with an adjusting bolt hole A4 and an adjusting bolt hole B8; the fixing bolt 5 passes through the adjusting bolt hole A4 and the adjusting bolt hole B8 to fix the base 3 on the bottom inner wall of the cable groove box 6.
The top of the vertical plate 2 and the top plate 1 are in a T-shaped joggle structure.
The size of the mortise A is matched with the top size of the vertical plate 2; the dimensions of the mortise B are matched with those of the top of the riser 2.
The upper surface of the base 3 is divided into two parts by the mortise B, namely a base A area and a base B area, and the surface area of the base A area is larger than that of the base B area.
The adjusting bolt hole A4 is formed in the surface of the base A area of the base 3;
the adjusting bolt hole B8 is formed in the surface of the base B area of the base 3.
The adjusting bolt hole A4 and the adjusting bolt hole B8 are long hole diameter structures, and the aperture length of the adjusting bolt hole A4 is larger than that of the adjusting bolt hole B8.
The base 3 is located to function as a fixed riser 2. The adjusting bolt holes A4 and the adjusting bolt holes B8 on the base 3 are two adjusting bolt holes with different lengths, and the fixing bolt 5 integrally fixes the base 3 to the bottom inner wall of the cable groove box 6. When the position of the base 3 needs to be adjusted, the fixing bolt 5 can be adjusted within the aperture length range of the adjusting bolt hole A4 and the adjusting bolt hole B8.
Compared with the conventional partition frame, the base 3 is divided into the base A area and the base B area, and the base A area and the base B area are different in length and area, so that the partition frame can adapt to the use requirements of different installation occasions.
The traditional separation frame is smaller because of the minor face size of bottom and does not possess the required intensity of support more cables, can produce the extrusion to the separation frame under the condition that certain side cable lays more, makes the separation frame produce the deformation and fall to other one side to extrude the space of laying of the cable of other side. And the minor face of traditional separate the frame bottom only can provide minimum position and be used for installing the fixed screw, need manual installation when separating the frame because there is not reserved hole, traditional base once install unable adjustment, otherwise need change cable bridge groove box. According to the bridge frame, the overall size of the base 3 is longer, and the larger-size areas in the base A area and the base B area can ensure the overall strength of the bridge frame and avoid deformation of the bridge frame;
the base 3 on two sides of the bottom of the vertical plate has different sizes, when the number and the volume of the cables arranged on two sides of the vertical plate are large, the base areas with smaller sizes in the base A area and the base B area can meet the use requirements, and the application occasions are wider; the adjusting bolt hole A4 and the adjusting bolt hole B8 which are arranged on the base 3 are used for connecting the fixing bolt 5, the pre-reserved adjusting bolt hole A4 and the pre-reserved adjusting bolt hole B8 can reduce the drilling workload in site construction, the design allows the spacer to be adjusted after the cable is laid, the relative positions of the fixing bolt in the long holes of the adjusting bolt hole A4 and the adjusting bolt hole B8 can be properly adjusted according to the cable arrangement condition after the fixing bolt 5 is unscrewed, and therefore the position of the base 3 in the cable bridge groove box 6 is reasonably arranged. The mortises B on the base 3 are used for mortises when the vertical plates 2 are installed.
The riser 2 plays a role in isolating cables to avoid electromagnetic interference, and meanwhile, the riser can divide the space in the cable bridge groove box to realize the physical isolation of the cables in the groove box.
The top plate and the vertical plate are connected to restrain the cable position and strengthen the integral strength of the partition frame. The traditional cable separates the setting of frame no roof or only has one side minor face, and its ability of isolated cable electromagnetic interference and restraint cable is general, and it is unable to be connected with the cable separates the frame simultaneously structurally, only relies on separating the frame base and is connected realization holistic fixed with cable groove box, and intensity is lower and produces torsional deformation easily.
The top plate and the vertical plate of the partition frame are of T-shaped structures, and when the partition frame is inclined to one side due to the fact that more cables on one side of the bridge frame are extruded, the T-shaped structure on the top of the partition frame forms rigid support on the cable trough box cover plate 7, so that the strength of the partition frame is improved. Compared with the traditional separation frame, the top structure of the scheme surrounds the cable in a larger size, can play a stronger constraint role on the cable, and increases the space distance between air gaps at two sides of the separation frame, so that the electromagnetic infection resistance is better.
A spacer is arranged in the cable tray 6 to distribute the spatial positions of the different types of cables in the tray. First, a cable tray 6 of an appropriate model and a spacer of an appropriate size are selected, and the number of spacer rows to be arranged in the tray 6 is confirmed. As shown in fig. 1, it is assumed that only one column of spacers needs to be arranged in the cable tray 6. The installation position of the partition frame is approximately determined according to the number of cables arranged on two sides of the partition frame.
The embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above examples, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
