Description

Technical Field

[0001] This utility model relates to the field of composite fireproof busbar technology, specifically a composite fireproof busbar. Background Technology

[0002] Fire-resistant busbar trunking consists of a shell coated with fire-retardant paint, busbars wrapped with fire-resistant mica tape, and a support frame made of fire-resistant insulating material. The support frame has multiple grooves, into which the busbars are inserted and fixed. There is a busbar trunking connection box at one end of the busbar trunking, and a busbar tap box inside the busbar trunking. Fire-resistant busbar trunking has excellent insulation performance and can be used continuously in normal environments and for more than one hour in fire environments. It is suitable for high-rise buildings and important facilities, replacing fire-resistant cables for power transmission and distribution.

[0003] Currently, when connecting conductors in busbar trunking, connectors are used for bonding and then bolts are used for fixing. This method has poor connection stability. When the conductors are clamped together, they are prone to separation when there is shaking, which affects power transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a composite fireproof busbar to solve the problem mentioned in the background art that the current busbar trunking is connected by connectors and then fixed with bolts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite fireproof busbar, comprising a first busbar trough, a second busbar trough, and a connector. The second busbar trough is located on the right side of the first busbar trough, and a connector is provided at the connection between the second busbar trough and the first busbar trough. The composite fireproof busbar further includes: a transmission mechanism disposed on both sides of the outer wall of the second busbar trough; and a tightening mechanism disposed on the left side of the transmission mechanism. The tightening mechanism can pull the first busbar trough to the right via the transmission mechanism, and the connection via the connector can increase its stability.

[0006] Preferably, a through hole is provided on the left side of the second busbar groove.

[0008] Preferably, the outer side of the protrusion has a diamond-shaped groove.

[0009] Preferably, a limiting block is machined inside the connection between the rotating rod and the slot block.

[0010] Preferably, the tightening mechanism includes: a connecting block, fixedly disposed on the left side of the rotating rod; a screw, fixedly disposed on the left side of the connecting block; and a threaded block, threaded on the outer wall of the screw, with the inner side of the threaded block connected to the outer wall of the first busbar groove; wherein, when the threaded block rotates, it can drive the first busbar groove to be pulled to the right.

[0011] Preferably, the threads on the outer walls of the two screws are opposite.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When this composite fireproof busbar is first used, the coordinated use of the slot block, rotating rod, first bevel gear, second bevel gear, connecting rod, and protrusion achieves the transmission of the tightening mechanism.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See also Figure 1-4 This utility model provides a technical solution: a composite fireproof busbar, including a first busbar trough 1, a second busbar trough 2, and a connector 3. The second busbar trough 2 is provided on the right side of the first busbar trough 1, and the connector 3 is provided at the connection between the second busbar trough 2 and the first busbar trough 1. The composite fireproof busbar also includes: a transmission mechanism 4 provided on both sides of the outer wall of the second busbar trough 2, and a tightening mechanism 5 provided on the left side of the transmission mechanism 4. The tightening mechanism 5 can pull the first busbar trough 1 to the right through the transmission mechanism 4 and connect it through the connector 3 to increase its stability. A through hole is provided on the left side of the second busbar trough 2.

[0020] Specifically, the transmission mechanism 4 includes: a slot block 401, a rotating rod 402, a first bevel gear 403, a second bevel gear 404, a connecting rod 405, and a protrusion 406;

[0021] The slot blocks 401 are fixedly installed on both sides of the outer wall of the second busbar trough 2. The slot blocks 401 are used to support the rotating rod 402. The rotating rod 402 is rotatably installed inside the slot blocks 401. The rotating rod 402 can drive the first bevel gear 403 to rotate. The first bevel gear 403 is fixedly installed on the right side of the rotating rod 402. The second bevel gear 404 is meshed on the bottom end of the outer wall of the first bevel gear 403. The connecting rod 405 is fixedly installed on the inner side of the second bevel gear 404. The connecting rod 405 is used for the simultaneous rotation of the second bevel gears 404 on both sides. The protrusion 406 is fixedly installed on the outer side of the second bevel gear 404. When the protrusion 406 is rotated by a specific tool, it can drive the second bevel gear 404 to rotate. The outer side of the protrusion 406 has a diamond-shaped groove. A limit block is machined inside the connection between the rotating rod 402 and the slot blocks 401.

[0022] More specifically, the tightening mechanism 5 includes: a connecting block 501, a screw 502, and a threaded block 503;

[0023] The connecting block 501 is fixedly installed on the left side of the rotating rod 402, the screw 502 is fixedly installed on the left side of the connecting block 501, and the threaded block 503 is threaded on the outer wall of the screw 502. The inner side of the threaded block 503 is connected to the outer wall of the first busbar groove 1. When the threaded block 503 rotates, it can drive the first busbar groove 1 to the right. The threads on the outer walls of the two screws 502 are opposite.

[0024] Working Principle: When the composite fireproof busbar is first used, after the busbar installation is complete and the two busbar slots need to be connected, the user first inserts connector 3 between the first busbar slot 1 and the second busbar slot 2. Then, the user inserts a diamond-shaped tool into the protrusion 406 and rotates it. The rotation of protrusion 406 drives the second bevel gear 404 to rotate simultaneously. Then, the rotation of the second bevel gear 404 drives the first bevel gear 403 to rotate simultaneously. Then, the rotation of the first bevel gear 403 drives the rotating rod 402 to rotate inside the slot block 401. When the rotating rod 402 rotates inside the slot block 401, it can connect the connector 3. Block 501 drives screw 502 to rotate. Then, through the internal thread engagement between screw 502 and threaded block 503, the rotation of screw 502 drives threaded block 503 to move to the right, indirectly driving the first busbar 1 to move to the right at the same time, tightening the connection between the first busbar 1 and the second busbar 2. After tightening, the user fixes the connection between the first busbar 1 and the second busbar 2 through connector 3. Then, by rotating screw 502 and inserting it into the inside of threaded block 503, the stability of the connection between the first busbar 1 and the second busbar 2 can be effectively increased, preventing the connection from shifting due to vibration or shaking, which would affect power transmission.
