TECHNICAL FIELD

[0001] The utility model relates to the field of dense bus duct, more specifically, it relates to a prevent formula dense bus duct connecting device. BACKGROUND

[0002] As a kind of efficient power transmission equipment, dense bus duct plays an important role in modern construction and industrial field. It is mainly composed of copper or aluminum busbar, insulating material, shell and other parts. The busbar in its interior is closely arranged, effectively reducing the volume of bus duct. Compared with traditional cable, it greatly reduces the space occupied under the same load flow requirement, which is extremely beneficial to space-limited places such as electrical shaft of high-rise building. Dense bus duct has the characteristics of high load flow, which can meet the power demand of large power equipment and safely and stably transmit a large amount of electric energy. Moreover, its heat dissipation performance is relatively good. Through reasonable structural design and heat dissipation mode, the heat generated during operation can be effectively dissipated, ensuring long-term reliable operation of equipment.

[0003] Dense bus ducts are usually connected by special connectors to form a complete and effective power transmission system. In actual operating environment, the connection part is easily disturbed by the vibration of the surrounding environment, and then loose, and even the connection part may fall off in severe cases. For example, in some industrial production scenes, there are strong vibrations generated by the continuous operation of a large number of machines and equipment in the factory building. These vibrations are continuously transmitted to the connection part of the bus duct, so that the connector is subjected to repeated impact force for a long time, and the connection part may gradually loosen, and the originally tight engagement state is destroyed.

[0004] Therefore, in order to solve the above technical problems, the present application provides a prevent formula dense bus duct connecting device. UTILITY MODEL CONTENT

[0011] Preferably, the head of the screw rod is fixedly connected with a handle facilitating the rotation of the screw rod, so as to facilitate the rotation of the screw rod by the staff.

[0012] Preferably, the other side of the vertical plate relative to the spring assembly is fixedly connected with a fixed plate at the upper part of the screw rod, and the fixed plate is threadedly connected with a fixing screw, so as to fix the state of the screw rod.

DETAILED DESCRIPTION

[0023] As Figures 1-4 shown, the utility model provides a prevent formula dense bus duct connector, including bottom cover plate 1, both sides of the top of bottom cover plate 1 are fixedly connected with vertical plate 2, all are screw -threaded connection on vertical plate 2 all screw rod 3, and the head of screw rod 3 all installs spring assembly 4, and installs bus duct connector 5 between two spring assemblies 4, spring assembly 4 includes the connecting shell 401 fixed in the side end of bus duct connector 5, the inner surface of connecting shell 401 is connected with connecting plate 403 through a plurality of damping springs 402, the surface of connecting plate 403 is rotatably connected with the screw rod 3 end through bearing 404, both sides of the inside of connecting shell 401 are fixedly connected with the guide rail 405 for sliding block 406 sliding, and connecting plate 403 is fixed between two sliding blocks 406, and the head of screw rod 3 is fixedly connected with handle 9 convenient for its rotation.

[0024] When installing, the plug-in parts of the two dense bus ducts are inserted between the plugs of the connector, after the insertion is completed, the bottom cover plate 1 is fixed with the shells of the two dense bus ducts, the two screw rods 3 are turned clockwise through the handle 9, thereby driving the two spring assemblies 4 to move to the middle part, thereby compressing the two ends of the bus duct connector 5 to realize the connection with the dense bus duct, then the screw rod 3 is turned clockwise (the screw rod 3 follows the rotation of the connecting plate 403), so that the screw rod 3 is pressed to move to the inside of the connecting shell 401, and finally reaches the middle part of the connecting shell 401. The connecting plate 403 will drive the movement of the sliding block 406 during the movement process, and the sliding block 406 slides along the guide rail 405 to maintain the linear movement of the connecting plate 403 and avoid being rotated by the screw rod 3. At this time, the damping spring 402 on the spring assembly 4 is in a compressed state, and through its rebound force, it will continuously apply a pressing force to the two ends of the bus duct connector 5 to avoid loosening of the bus duct connector 5 due to external vibration. At the same time, when the bus duct connector is vibrated by external influence, the damping spring 402 will also stretch and contract, according to Hooke's law, the damping spring 402 will generate a spring force opposite to the direction of the external force. This spring force tries to resist the deformation of the spring, thereby playing a certain role in buffering and reducing the vibration amplitude of the object connected to the spring, and finally achieving the purpose of anti-vibration, which can more effectively avoid the influence of external vibration on the connection part of the connector and the dense bus duct, thereby achieving the purpose of preventing disconnection and loosening. Conversely, by turning the screw rod 3 counterclockwise through the handle 9, the screw rod 3 drives the two spring assemblies 4 to move to both sides, thereby releasing the fastening connection state between the plug-in part of the dense bus duct and the plug of the bus duct connector 5.

[0025] Further, the other side of the vertical plate 2 relative to the spring assembly 4 is fixedly connected with a fixed plate 10 above the upper part of the screw rod 3. The fixed plate 10 is threadedly connected with a fixed screw 11, that is, after the connection between the dense bus duct and the bus duct connector 5 is completed by rotating the screw rod 3, the fixed screw 11 is turned clockwise to move downward along the fixed plate 10, thereby abutting against the outer wall of the screw rod 3 to limit the rotation of the screw rod 3 and avoid the influence of vibration on the connection between the dense bus duct and the bus duct connector 5.

[0026] Meanwhile, the top end of the bottom cover plate 1 is detachably connected with the upper cover plate 6, and the specific structure of the detachable connection is as follows: the top end of the vertical plate 2 is fixedly connected with threaded rods 7 on both sides, and the top end of the upper cover plate 6 is provided with through holes 8 for the threaded rods 7 to pass through, that is, after the bottom cover plate 1 is fixed with the dense bus duct shell and the connector is connected with the connecting part of the dense bus duct, the through holes 8 on the upper cover plate 6 are aligned with the threaded rods 7 on the vertical plate 2 and are inserted, after the insertion, the nuts are rotated clockwise to be installed on the threaded rods 7 and are moved downward along the threaded rods 7 until the top end of the upper cover plate 6 is abutted, so that the upper cover plate 6 is fixed with the vertical plate 2, and thus the bus duct connector 5 is located in the space enclosed by the upper cover plate 6, the bottom cover plate 1 and the two vertical plates 2, and dust can be well blocked.
