[0023] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] See Figure 1-2A cable tray splicing assembly includes a connecting frame 1, which is fixed on both sides of the cable tray. The bottom of each of the two connecting frames 1 is provided with an insertion plate 2 and a slot 3. A pad 8 is installed on the upper end of the insertion plate 2 through a groove. The pad 8 is a thermoplastic block. The upper surface of the pad 8 and the lower surface of the insertion plate 2 are tightly connected to the upper and lower side walls of the slot 3. The insertion plate 2 and the slot 3 are connected to complete the docking. When the pad 8 melts, the upper part of the insertion plate 2 loses support, which causes the connection point of the two connecting frames 1 to deflect.

[0025] See Figure 1 , 4 The front end of the insertion plate 2 has a chamfered edge 9 with a semi-circular cross-section. Spring cavities 13 are fixed on both sides of the slot 3. A limiting rod 14 is slidably installed in the spring cavity 13 through a spring mechanism. The limiting rod 14 has a second inclined surface 18 facing the insertion plate 2. A limiting groove 15 is provided on the side of the insertion plate 2 corresponding to the limiting rod 14. A spring ring 16 is fixedly installed in the spring cavity 13 of the limiting rod 14. A support spring 17 is sleeved on the limiting rod 14. The two ends of the support spring 17 are connected to the spring cavity 13 and the spring ring 16, respectively. The limiting rod 14 is pushed into the limiting groove 15 by the support spring 17 to limit the insertion plate 2. A lifting button 6 is fixedly installed on the outside of the spring cavity 13 of the limiting rod 14. Pulling the lifting button 6 releases the insertion plate 2. When the chamfered edge 9 is connected to the bottom of the slot 3, the limiting groove 15 and the limiting rod 14 are aligned.

[0026] See Figure 1-3 The limiting groove 15 is located at the center of the chamfered edge 9. When the insertion plate 2 deflects, the insertion plate 2 rotates upward around the limiting groove 15 until the upper surface of the insertion plate 2 is blocked by the upper side of the slot 3 opening. The vertical wall of the connecting frame 1 is provided with symmetrical protruding frames 4. A dry powder chamber 7 is provided between the two protruding frames 4 on the same side. The dry powder chamber 7 has through strip-shaped openings on both sides. A fragile strip 11 is fixedly provided on the strip-shaped opening to close it. A pressure plate 10 is fixedly provided on the protruding frame 4 corresponding to the fragile strip 11. The pressure plate 10 is a flat plate. The pressure plate 10 presses on the fragile strip 11 through the first inclined surface 12. The structural strength of the fragile strip 11 is such that when the insertion plate 2 rotates around the limiting rod 14, the pressure plate 10 presses the fragile strip 11 to break. When the protruding frame 4 deflects, it squeezes into the dry powder chamber 7. The pressure plate 10 on it squeezes the fragile strip 11 on both sides of the dry powder chamber 7 and releases the dry powder. The top of the connecting frame 1 is provided with a lifting hole 5. Its lifting rope is located in the middle of the two connecting frames 1 and is connected to the lifting hole 5 respectively. When the pad 8 melts, the upper end of the connecting frame 1 narrows under the pull of the lifting rope.

[0027] The cable tray splicing assembly of this utility model is simple and easy to plug in the cable trays. In the event of a fire, it can automatically spray dry powder for fire extinguishing. It is highly safe, practical and suitable for widespread application.

[0028] For specific usage, please refer to... Figure 1 , 4 When the two connecting frames 1 are docked, the insertion plate 2 is inserted into the slot 3. During this process, the chamfered edge 9 at the front end of the insertion plate 2 presses against the second inclined surface 18, causing the limiting rod 14 to retract into the spring cavity 13. When the chamfered edge 9 is in contact with the bottom of the slot 3, the limiting rod 14 springs into the limiting groove 15, thus fixing the insertion plate 2 in the slot 3. At this time, the upper surface of the pad 8 and the lower surface of the insertion plate 2 are tightly connected to the upper and lower side walls of the slot 3, and the cable tray is docked and fixed.

[0029] Reference Figure 1-3 When laying cable trays, a dry powder chamber 7 can be optionally installed. The dry powder chamber 7 is sandwiched between two connecting frames 1. In the event of a fire, the pad 8 melts when heated. Under the action of gravity, the two connecting frames 1 deflect. When the protruding frame 4 above deflects, it presses against the dry powder chamber 7. The pressure plate 10 on it presses against the fragile strips 11 on both sides of the dry powder chamber 7. After the fragile strips 11 break, the dry powder in the dry powder chamber 7 bursts out and rushes towards the cable trays on both sides.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
