Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray connection structure with a self-locking function. Background Technology

[0002] Cable trays are devices used to support and lay cables. The covers of cable trays cover the trays, serving to protect the cables, prevent dust and debris from entering, and improve the appearance. The shape and size of the cover plate match the tray, and screws are usually used to connect the cover plate and the tray. During maintenance, the cover plate and the tray need to be disassembled to confirm that everything is correct before reinstallation. After repeated disassembly and assembly or long-term use, the connection points are prone to damage, and the disassembly and assembly process is relatively cumbersome. Small parts such as screws are also easy to lose during use, causing inconvenience for installation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cable tray connection structure with a self-locking function includes a tray and a cover. The tray includes a base plate and side plates perpendicular to both sides of the base plate. Several locking strips are evenly spaced along the length of the side plates near their upper edges. One end of each locking strip is connected to a side plate, and the other end extends along the length of the tray. A gap exists between the locking strip and the side plate. The cover includes a top plate and downward-facing sidewalls perpendicular to both sides of the top plate. Several slots are evenly spaced along the length of the sidewalls. The spacing between adjacent slots is the same as the spacing between the locking strips. An opening communicating with a slot is provided at the lower edge of the sidewall. The end of the slot away from the opening extends in the same direction as the locking strip. When the cover is placed on the tray, the locking strip enters the slot from the opening. After the cover moves in the opposite direction along the extension direction of the locking strip, the sidewall of the slot edge is embedded in the gap between the locking strip and the side plate.

[0006] Preferably, the side plate has several notches evenly spaced along its length near the upper edge, and the retaining strip is disposed at one end of the notch, and the retaining strip is integrally formed with the side plate.

[0007] Preferably, the card strip is provided with a protrusion that protrudes towards the side plate, and the side wall is provided with an opening corresponding to the protrusion.

[0008] Preferably, the top plate has downwardly extending obstructions on both sides, and the locking strip is located inside the obstructions.

When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0021] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] As attached Figure 1 Appendix Figure 2 The diagram illustrates a cable tray connection structure with a self-locking function according to this invention. It includes a tray 1 and a cover 2. The tray 1 comprises a base plate 11 and side plates 12 perpendicular to both sides of the base plate 11. Several locking strips 13 are evenly spaced along the length of the side plates 12 near their upper edges. One end of each locking strip 13 is connected to the side plate 12, and the other end extends along the length of the tray 1. A gap exists between the locking strip 13 and the side plate 12. In this embodiment, several notches 14 are evenly spaced along the length of the side plates 12 near their upper edges. The locking strips 13 are connected to one end of each notch 14. The locking strips 13 and the side plates 12 are integrally formed, making the structure more reliable, improving the overall integrity of the product, and increasing production efficiency and material utilization.

[0023] The cover 2 includes a top plate 21 and side walls 22 perpendicular to both sides of the top plate 21 and extending downwards. Several slots 23 are evenly spaced along the length of the side walls 22. The spacing between adjacent slots 23 is the same as the spacing between the locking strips 13. An opening 24 communicating with the slots 23 is machined on the lower edge of the side walls 22. The end of the slot 23 away from the opening 24 extends in the same direction as the locking strips 13. When the cover 2 is placed on the tray 1, the locking strips 13 enter the slots 23 from the opening 24. After the cover 2 moves in the opposite direction along the extension direction of the locking strips 13, the side wall 22 at the edge of the slot 23 is embedded in the gap between the locking strips 13 and the side plate 12, so that the cover 2 and the tray 1 can be quickly connected. The cover 2 will not easily fall off the tray 1, and the installation is convenient and quick. Because of the height difference during cable installation, some cable trays need to be installed at an angle. In this case, simply install the tray 1 of this utility model at an angle so that the locking strip 13 points diagonally upward. When the cover 2 is installed, it will be locked at a certain height by the locking strip 13 and will not slip off the tray 1 due to gravity or other reasons. The connection is reliable and practical.

[0024] As attached Figure 3 As shown, in another embodiment, a protrusion 131 protruding towards the side plate 12 is formed on the card strip 13, and an opening 221 corresponding to the protrusion 131 is machined on the side wall 22. When the cover 2 is moved so that the side wall 22 of the edge of the card slot 23 is embedded in the gap between the card strip 13 and the side plate 12, the protrusion 131 is engaged in the opening 221, so that a more reliable connection is formed between the tray 1 and the cover 2. When the cover 2 is removed, only a little force needs to be applied in the opposite direction of the extension direction of the card strip 13, which is convenient for repeated disassembly and assembly.

[0025] As attached Figure 4 As shown, the top plate 21 has downwardly extending baffles 25 on both sides. The baffles 25 and the top plate 21 are connected by an arc, which makes it easy for impurities to slide off the cover 2. The retaining strip 13 is located inside the baffle 25. The baffle 25 covers the retaining strip 13 to prevent it from getting caught on other things and affecting its use, and to make it easier for the hand to grip the cover 2.

[0026] The top of the side plate 12 has an inwardly bent side edge 15, which serves to strengthen the structure and make the tray 1 more stable and less prone to bending. When the upper edge of the locking strip 13 contacts the upper edge of the locking groove 23, there is a gap between the top of the side plate 12 and the top plate 21, which reduces the processing precision requirements and prevents the cover 2 and the top of the side plate 12 from colliding.

[0027] This utility model discloses a cable tray connection structure with a self-locking function. A locking strip 13 is machined on the side plate 12 of the tray 1, and a locking groove 23 is machined on the side wall 22 of the cover 2. After the cover 2 is placed on the tray 1 and the locking strip 13 enters the locking groove 23, the cover 2 is moved along the length direction to make the locking strip 13 and the locking groove 23 engage and connect. No screws or other accessories are required, and the installation and disassembly are convenient and quick. It effectively prevents the cover 2 from falling off and is convenient for maintenance, disassembly and reassembly for repeated use.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
