Abstract

This utility model discloses a busbar trunking connection device, including a connecting seat, a busbar trunking body, a cover plate, and a connector. The cover plate is connected to a sealing air cushion and an air cylinder. A first spring is connected inside the air cylinder, and the first spring is connected to a piston plate. The piston plate is connected to a piston rod, and the piston rod is connected to a pressing plate. An air supply pipe is connected to the periphery of the air cylinder, and the air supply pipe is fixedly connected to the sealing air cushion. Several air inlets are opened on the upper surface of the air cylinder. This utility model solves the problem that in existing connection cover plates are fixed to the connecting seat with bolts. Although this ensures the connection strength between the connecting cover plate and the connecting seat, the overall connection sealing strength is insufficient.

Description

Technical Field

[0001] This utility model belongs to the field of busbar trunking technology, and in particular relates to a busbar trunking connection device. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] When connecting busbar trunking, two busbar trunking sections are typically inserted into a connector, and bolts are used to connect and fix the busbar trunking sections and the connector. There is a certain space between the two busbar trunking sections, and a connector is inserted between the two busbar trunking sections. The connector is then secured by the clips between the connector and the busbar trunking sections. Finally, a cover plate is placed on the connector and the bolts are tightened to secure it.

[0004] However, the above-mentioned busbar trunking connection device has the following defects: the existing connection cover is fixed to the connection seat by bolts. Although the connection strength between the connection cover and the connection seat is guaranteed, the overall connection sealing strength is insufficient. Since busbar trunking is needed in many power supply locations, such as reservoirs, the humidity in reservoirs is high. Insufficient sealing can easily allow external moisture to enter the inside of the connector, causing short circuits and reducing the safety of busbar trunking. To solve the above problems, a busbar trunking connection device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a busbar trunking connection device that solves the problem that the existing connection cover is fixed to the connection seat with bolts. Although this ensures the connection strength between the connection cover and the connection seat, the overall connection sealing strength is insufficient. Since busbar trunking is needed in many power supply locations, such as reservoirs, the lack of sealing can easily allow external moisture to enter the connector due to the high humidity in reservoirs, causing short circuits and reducing the safety of busbar trunking.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a busbar trunking connection device, comprising a connecting seat, a busbar trunking body, a cover plate, and a connector. The bottom surface of the cover plate is grooved, and a sealing air cushion is fixedly connected to the bottom surface of the cover plate. An air cylinder is fixedly connected to the upper surface of the cover plate, and a first spring is fixedly connected to the bottom surface of the inner wall of the air cylinder. A piston plate is fixedly connected to the upper end of the first spring, and a piston rod is fixedly connected to the upper surface of the piston plate. A pressing plate is fixedly connected to the upper end of the piston rod. A plurality of air supply pipes are fixedly connected to the circumferential side of the air cylinder, and the bottom end of each air supply pipe is fixedly connected to the sealing air cushion.

[0008] Preferably, the upper surface of the cover plate is provided with a plurality of fixing grooves, and fixing members are installed in the fixing grooves. The fixing members are fixedly connected to the connecting seat. A guide rod is fixedly connected in the fixing member. A second spring and a plurality of guide rings are connected to the peripheral side of the guide rod. A connecting rod is fixedly connected to the peripheral side of the guide rings. A fixing rod is fixedly connected to the upper end of the connecting rod. A push-pull rod is connected to the peripheral side of the fixing rod. A moving block is connected to the upper end of the push-pull rod. A pull rod is fixedly connected to the upper surface of the moving block.

[0009] Preferably, the connector is connected and fixed to the busbar trunking body by a snap-fit.

[0010] Preferably, both the piston plate and the piston rod are slidably engaged with the air cylinder.

[0011] Preferably, a sealing ring is bonded to the connection between the busbar trunking body and the connecting seat.

[0012] Preferably, both the pull rod and the fixing rod are slidably engaged with the fixing component.

[0013] Preferably, the movable block and the fixed rod are both hinged to the push-pull rod, and the guide ring is slidably engaged with the guide rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up an air cylinder and a sealing air cushion, after the cover plate is fixed, press down on the pressing plate. The pressing plate pushes the piston plate downward through the piston rod, and the piston plate forces the gas out. The gas is then transported to the sealing air cushion through the air supply pipe, so that the sealing air cushion is quickly inflated. Under the sealing effect of the sealing air cushion, the sealing strength between the cover plate and the connecting seat is improved, and the short circuit caused by water vapor entering the connecting seat is avoided, thereby improving the safety of the busbar trunking body.

[0016] 2. This utility model, by setting a fixed rod and a second spring, allows for easy installation of the cover plate. When the pull rod is pulled upward, it causes the moving block to move upward. The moving block then pulls the two fixed rods towards each other via a push-pull rod. Due to the limiting effect of the guide ring, the fixed rods can only move horizontally, compressing the second spring and causing it to retract into the fixing component. The fixing component is then inserted into the fixing groove. Releasing the pull rod causes the second spring to reset, pushing the fixed rod out and fixing the cover plate. This eliminates the need for bolt tightening, making the operation simple and quick.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figures 1-4 As shown, this utility model is a busbar trunking connection device, including a connecting seat 1, a busbar trunking body 2, a cover plate 3, and a connector 11. The bottom surface of the cover plate 3 is grooved, and a sealing air cushion 12 is fixedly connected to the bottom surface of the cover plate 3. An air cylinder 4 is fixedly connected to the upper surface of the cover plate 3. A first spring 14 is fixedly connected to the bottom surface of the inner wall of the air cylinder 4. A piston plate 13 is fixedly connected to the upper end of the first spring 14. A piston rod 8 is fixedly connected to the upper surface of the piston plate 13. A pressing plate 7 is fixedly connected to the upper end of the piston rod 8. Several air supply pipes 6 are fixedly connected to the peripheral side of the air cylinder 4. The bottom end of the air pipe 6 is fixedly connected to the sealing air cushion 12. After the cover plate 3 is fixed, the pressing plate 7 is pressed down by setting the air cylinder 4 and the sealing air cushion 12. The pressing plate 7 pushes the piston plate 13 downward through the piston rod 8, and the piston plate 13 pushes the gas out. The gas is delivered to the sealing air cushion 12 through the air pipe 6, so that the sealing air cushion 12 is quickly supported. Under the sealing effect, the sealing strength between the cover plate 3 and the connecting seat 1 is improved, and the short circuit caused by water vapor entering the connecting seat 1 is avoided, thereby improving the safety of the bus trunking body 2.

[0027] The upper surface of the cover plate 3 is provided with several fixing grooves, and fixing parts 9 are installed in the fixing grooves. The fixing parts 9 are fixedly connected to the connecting seat 1. A guide rod 19 is fixedly connected in the fixing part 9. A second spring 21 and several guide rings 20 are connected to the peripheral side of the guide rod 19. A connecting rod 22 is fixedly connected to the peripheral side of the guide rings 20. A fixing rod 18 is fixedly connected to the upper end of the connecting rod 22. A push-pull rod 17 is connected to the peripheral side of the fixing rod 18. A moving block 16 is connected to the upper end of the push-pull rod 17. A pull rod 15 is fixedly connected to the upper surface of the moving block 16. By setting the fixing rod 18 and the second spring 21, a second spring 21 and several guide rings 20 are connected to the peripheral side of the fixing rod 18. When installing the cover plate 3, the second spring 21 is pulled upward by the pull rod 15. The pull rod 15 drives the moving block 16 to move upward. The moving block 16 pulls the two fixed rods 18 to move towards each other through the push-pull rod 17. Due to the limiting effect of the guide ring 20, the fixed rods 18 can only move horizontally, compressing the second spring 21 and thus retracting into the fixing member 9. Then, the fixing member 9 is inserted into the fixing groove, the pull rod 15 is released, the second spring 21 returns to its original position, and pushes the fixing rods 18 to pop out, fixing the cover plate 3. There is no need to tighten the bolts for fixing, and the operation is simple and quick.

[0028] The connector 11 is connected and fixed to the busbar trunking body 2 by a snap-fit.

[0029] Both piston plate 13 and piston rod 8 are in sliding fit with air cylinder 4.

[0030] A sealing ring 10 is bonded to the connection between the busbar trunking body 2 and the connecting seat 1.

[0031] Both the pull rod 15 and the fixing rod 18 are in sliding fit with the fixing part 9.

[0032] Both the movable block 16 and the fixed rod 18 are hinged to the push-pull rod 17, and the guide ring 20 is slidably engaged with the guide rod 19.

[0033] Example:

[0034] like Figures 1-4 As shown, the method of using the busbar trunking connection device of this utility model is as follows: When using this utility model, after the busbar trunking body 2 and connector 11 are installed, the cover plate 3 is then installed and fixed. When installing the cover plate 3, pull the pull rod 15 upward. The pull rod 15 drives the moving block 16 to move upward. The moving block 16 pulls the two fixed rods 18 to move towards each other through the push-pull rod 17. Due to the limiting effect of the guide ring 20, the fixed rods 18 can only move horizontally, compressing the second spring 21 and thus retracting into the fixing member 9. Then, the fixing member 9 is inserted into the fixing groove. The pull rod 15 is released, the second spring 21 is reset, and the fixing rods 18 are pushed out to fix the cover plate 3. It is not necessary to fix it by tightening bolts. It can also be retracted by pressing the fixing rods 18 on both sides. The same principle applies during disassembly and maintenance, which can realize the quick disassembly and assembly of the cover plate 3. After the cover plate 3 is fixed, press the pressing plate 7 downward. The pressing plate 7 pushes the piston plate 13 downward through the piston rod 8, and the piston plate 13 forces the gas out. The gas is then transported to the sealing gas pad 12 through the gas supply pipe 6, causing the sealing gas pad 12 to quickly expand. Under the sealing effect of the sealing gas pad 12, the sealing strength between the cover plate 3 and the connecting seat 1 is improved, preventing short circuits caused by water vapor entering the connecting seat 1. This improves the safety of the busbar trunking body 2. In addition, the setting of the sealing ring 10 makes the connection between the busbar trunking body 2 and the connecting seat 1 more airtight. It should be noted that, in places not shown in the figure, one-way valves are fixedly connected to the periphery of the air cylinder 4 and the gas supply pipe 6, allowing only air to enter. The air inlet valve of the air cylinder 4 is located near the bottom of the air cylinder 4. A plug is threadedly connected to the rear surface of the cover plate 3. One end of the plug extends into the sealing gas pad 12 for releasing the air from the sealing gas pad 12, making it convenient to disassemble the cover plate 3.
