[0039] like Figures 1-6 The butterfly-shaped quick-connect fitting shown can be widely used for connections between cable trays;

[0040] A butterfly-shaped quick-connect fitting includes a first connector 1 and a second connector 2. The first connector 1 includes a first left connecting piece 11 and a first right connecting piece 12, which are staggered and connected. The lower end of the connection between the first left and right connecting pieces 11 and 12 has a first limiting slot 13. The first connector 1 has first connecting holes 14 on both its left and right sides. The second connector 2 includes a second left connecting piece 21 and a second right connecting piece 22, which are staggered and connected. The upper end of the connection between the first connector 1 and the second right connecting piece 22 has a second limiting slot 23, and the left and right sides of the second connector 2 are provided with second connecting holes 24. When the first connector 1 and the second connector 2 are assembled, the first limiting slot 13 coincides with the second limiting slot 23, the first left connecting piece 11 and the second left connecting piece 21 form a left connecting groove 3, and the first right connecting piece 12 and the second right connecting piece 22 form a right connecting groove 4. The left connecting groove 3 and the right connecting groove 4 are respectively used to connect the ends of two adjacent cable trays, and the first connecting hole 14 and the second connecting hole 24 correspond to each other. It should be noted that two adjacent cable trays are connected by two butterfly quick-connect fittings. The two butterfly quick-connect fittings are fixed to the two side walls of the cable trays respectively. Specifically, the first left connecting piece 11 is attached to the outer side wall of the cable tray, the second left connecting piece 21 is attached to the inner side wall of the cable tray, the first right connecting piece 12 is attached to the inner side wall of the other cable tray, and the second right connecting piece 22 is attached to the inner side wall of the other cable tray. The side wall of the cable tray has through holes corresponding to the first connecting hole 14 and the second connecting hole 24. Bolts are then passed through the first connecting hole 14, the through holes, and the second connecting hole 24, and then tightened with nuts to fix the quick-connect fittings to the cable trays. In other words, only two bolts are needed to connect one butterfly quick-connect fitting to two cable trays, and only four bolts are needed to connect two adjacent cable trays, which greatly improves the installation efficiency.

[0041] The beneficial effects of this utility model are as follows: the setting of the first limiting slot 13 and the second limiting slot 23 allows the first connecting piece 1 and the second connecting piece 2 to be interlocked, so that the first connecting piece 1 and the second connecting piece 2 are assembled together, thereby the first left connecting piece 11 and the second left connecting piece 21 cooperate to form the left connecting groove 3, and the first right connecting piece 12 and the second right connecting piece 22 cooperate to form the right connecting groove 4. The ends of two adjacent cable trays extend into the left connecting groove 3 and the right connecting groove 4 respectively. Then, bolts are used to pass through the first connecting hole 14, the side wall of the cable tray and the second connecting hole 24 to fix the cable tray to the first connecting piece 1 and the second connecting piece 2, thereby realizing the docking of two adjacent cable trays, which greatly reduces the cost and complexity.

[0042] Please refer to Figure 1In one possible implementation, the lower end of the first left connecting piece 11 has a first connecting plate 15, which is perpendicular to the first left connecting piece 11; the lower end of the second right connecting piece 22 has a second connecting plate 25, which is perpendicular to the second right connecting piece 22; the end of the first connecting plate 15 is engaged with the end of the second connecting plate 25. It should be noted that the arrangement of the first connecting plate 15 and the second connecting plate 25 can limit and support the cable tray, thereby improving the stability of the cable tray after it extends into the left connecting groove 3 and the right connecting groove 4. In addition, when the first connecting piece 1 and the second connecting piece 2 are assembled, they can be first staggered in an "X" shape and then rotated to ensure that the first connecting piece 1 and the second connecting piece 2 can be smoothly assembled and engaged.

[0043] Please refer to Figure 4 and Figure 5 In one possible implementation, the end of the first connecting plate 15 is provided with a limiting groove 151, and the end of the second connecting plate 25 is provided with a limiting protrusion 251, the limiting protrusion 251 extending into the limiting groove 151. It should be noted that the cooperation between the limiting protrusion 251 and the limiting groove 151 allows the first connecting plate 15 and the second connecting plate 25 to be engaged, which helps to improve the stability of the connection between the first connecting member 1 and the second connecting member 2.

[0044] Please refer to Figures 3 to 5 In one possible implementation, the lower end of the first left connecting piece 11 is provided with a slot 111, and the side wall of the second connecting plate 25 is provided with a locking head 252, which is inserted into the slot 111. It should be noted that the locking head 252 cooperates with the slot 111 to make the first connecting piece 1 and the second connecting piece 2 snap together, which can prevent the first connecting piece 1 and the second connecting piece 2 from loosening. When the first connecting piece 1 and the second connecting piece 2 are assembled, they can form a mechanical self-locking mechanism, requiring external force to separate the first connecting piece 1 and the second connecting piece 2, thereby further improving the stability of the connection between the first connecting piece 1 and the second connecting piece 2. In addition, the bolt bears the longitudinal shear force, and the locking head resists the lateral vibration. The division of labor is clear and they are redundant backups of each other, which greatly improves the safety factor of the cable tray.

[0045] Please refer to Figure 1 In one possible implementation, a right connecting seam 41 is provided between the first right connecting piece 12 and the second connecting plate 25, and the right connecting seam 41 communicates with the right connecting groove 4. It should be noted that the right connecting seam 41 is used to allow the bottom of the cable tray to pass through. The end of the cable tray located on the right side of the quick connector extends into the right connecting seam 41 and the right connecting groove 4, and the bottom surface of the cable tray contacts the bottom surface of the right connecting seam 41 to limit the cable tray, thereby preventing the cable tray from moving up and down and improving the stability of the connection between the cable tray and the quick connector.

[0046] Please refer to Figure 4In one possible implementation, the lower end of the first right connecting piece 12 is provided with a first guide slope 121, which mates with the right connecting seam 41. It should be noted that the first guide slope 121 can guide the cable tray on the right side of the quick-connect fitting. When the bottom of the cable tray on the right side of the quick-connect fitting extends into the right connecting seam 41, it can smoothly enter under the guidance of the first guide slope 121, which helps improve installation efficiency.

[0047] Please refer to Figure 1 In one possible implementation, a left connecting seam 31 is provided between the second left connecting piece 21 and the first connecting plate 15, and the left connecting seam 31 communicates with the left connecting groove 3. It should be noted that the left connecting seam 31 is used to allow the bottom of the cable tray to pass through. The end of the cable tray located on the left side of the quick connector extends into the left connecting seam 31 and the left connecting groove 3, and the bottom surface of the cable tray contacts the bottom surface of the left connecting seam 31 to limit the cable tray, thereby preventing the cable tray from moving up and down and improving the stability of the connection between the cable tray and the quick connector.

[0048] Please refer to Figure 5 In one possible implementation, the lower end of the second left connecting piece 21 is provided with a second guide slope 212, which mates with the left connecting seam 31. It should be noted that the second guide slope 212 can guide the cable tray on the left side of the quick-connect fitting. When the bottom of the cable tray on the left side of the quick-connect fitting extends into the left connecting seam 31, it can smoothly enter under the guidance of the second guide slope 212, which helps improve installation efficiency.

[0049] Please refer to Figure 1 In one possible implementation, a first connecting portion 16 is provided between the first left connecting piece 11 and the first right connecting piece 12, and the two sides of the first connecting portion 16 are respectively arcuately connected to the first left connecting piece 11 and the first right connecting piece 12, and the first connecting portion 16 extends into the second limiting slot 23; a second connecting portion 26 is provided between the second left connecting piece 21 and the second right connecting piece 22, and the two sides of the second connecting portion 26 are respectively arcuately connected to the second left connecting piece 21 and the second right connecting piece 22, and the second connecting portion 26 extends into the first limiting slot 13. It should be noted that the first connecting part 16 is perpendicular to the first left connecting piece 11 and the first right connecting piece 12, so that the first left connecting piece 11 and the first right connecting piece 12 are misaligned and parallel. The second connecting part 26 is perpendicular to the second left connecting piece 21 and the second right connecting piece 22, so that the second left connecting piece 21 and the second right connecting piece 22 are misaligned and parallel. When the first connecting piece 1 and the second connecting piece 2 are assembled, the end of the first connecting part 16 contacts the end of the second connecting part 26, and the end of the cable tray abuts against the first connecting part 16 and the second connecting part 26.

[0050] Please refer to Figure 1In one possible implementation, the first right connecting piece 12 and the second left connecting piece 21 have the same structure. It should be noted that the volume of the first right connecting piece 12 is smaller than that of the first left connecting piece 11, and the volume of the second left connecting piece 21 is smaller than that of the second right connecting piece 22. This allows the first connecting piece 1 and the second connecting piece 2 to form a left connecting seam 31 and a right connecting seam 41 after assembly, allowing the bottom of the cable tray to pass through. Furthermore, both the first connecting piece 1 and the second connecting piece 2 are integral structures, improving their structural strength. This quick-connect fitting features good compatibility, convenient maintenance, and a reversible disassembly design, supporting the reuse of the cable tray and greatly meeting customer needs.

[0051] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
