Description

Technical Field

[0001] This utility model relates to the field of cable tray accessories, specifically to a cable tray side plate. Background Technology

[0002] There are many types of cable trays, including metal and extruded. Extruded cable trays require a base plate to be installed between the lower slots at the bottom of the two side plates. After fixing, wiring / conduit is installed, and finally, a cover plate is attached to the top of the two side plates to complete the installation. Currently, the cover plate is fixed by matching the slots on the top of the side plates with the hooks on both sides of the bottom width of the cover plate. The two need to be fixed by first bringing the upper parts of the two side plates together, and then installing the cover plate. The elasticity between the two side plates is used to achieve the engagement of the hooks and slots. Therefore, the rigidity of the bottom of the side plates is required to be high. If the installation is not done properly, the lower slot between the bottom of the side plate and the base plate may break or deform, which will affect the reliability of the cover plate.

[0005] The present invention is further configured such that, at the connection between the vertical plate and the horizontal plate, there are a plurality of vertical support pieces that are formed by stamping material from the horizontal plate and extending vertically downward and spaced apart along the length of the reinforcing rib; at the connection between the horizontal plate and the vertical plate, there are a plurality of horizontal support pieces that are formed by stamping material from the vertical plate and extending horizontally outward in the direction of the outward extension of the support pieces and spaced apart along the length of the reinforcing rib; the ends of the vertical support pieces are flush with the lower surface of the lower groove edge, and the ends of the horizontal support pieces are flush with the side of the side plate facing away from the lower groove edge.

[0006] The present invention is further configured such that the inner support plate and the upper support plate are located on the same virtual cross section one of the reinforcing rib plate; and the outer support plate and the lower support plate are located on the same virtual cross section two of the reinforcing rib plate.

[0007] The present invention is further configured such that the vertical support plate is located between adjacent horizontal support plates; the vertical support plate is located on virtual section three between virtual section one and virtual section two, and the horizontal support plate is located on virtual section four between virtual section two and virtual section one.

[0009] The present invention is further configured such that the ends of the vertical support plate and the horizontal support plate are rounded on both sides corresponding to the length direction of the reinforcing rib.

[0010] The present invention is further configured such that the reinforcing rib is made of metal; the vertical plate has a vertical recess extending along the length of the reinforcing rib on its cross section, and the horizontal plate has a horizontal recess extending along the length of the reinforcing rib on its cross section.

By embedding an L-shaped reinforcing rib between the side plate and the lower groove edge, the rigidity between the side plate and the lower groove edge is improved, thereby enhancing the fixing reliability of the upper end of the side plate when installing the cover plate. Since the reinforcing rib is embedded during the extrusion molding of the side plate, its position in the cavity is prone to deviation. Therefore, several inner support plates, outer support plates, upper support plates, and lower support plates are formed on the reinforcing rib by stamping, which are spaced apart along its length. This allows the reinforcing rib to be reliably positioned by using the inner support plates, outer support plates, upper support plates, and lower support plates to abut against the inner wall of the cavity when passing through the cavity. This satisfies the requirement of the reinforcing rib being centrally arranged in the side plate and the lower groove edge, ensuring the uniformity of the extrusion coating. 2. Vertical and horizontal support plates are installed to assist in positioning at the junction of the vertical and horizontal plates, further improving the positioning accuracy of the reinforcing ribs; 3. Virtual section one is located between adjacent virtual section two, so that the inner and upper support plates and the outer and lower support plates in the length direction of the reinforcing rib are arranged alternately; this realizes that after arranging the inner and upper support plates simultaneously in the length direction of the reinforcing rib, the horizontal support plates are arranged, then the outer and lower support plates are arranged simultaneously, and then the vertical support plates are arranged to form a cycle; 4. During the molding process, the reinforcing ribs must move together with the side plate body; rounding can reduce scratches between the ribs and the mold cavity. 5. Vertical and horizontal recesses can be set in several groups at intervals and side by side as needed to improve overall rigidity. Attached Figure Description

[0034] In this embodiment, the ends of the vertical support plate 213 and the horizontal support plate 223 are both rounded 23 on both sides corresponding to the length direction of the reinforcing rib plate 20.

[0035] In the above structure, the reinforcing rib 20 needs to move together with the side plate 10 during molding, and the rounded 23 can reduce the scraping between it and the cavity.
