Bus duct jack box locking device

Abstract

The invention relates to the technical field of bus duct locking, and discloses a bus duct jack box locking device, which comprises a main body, and the bottom of the main body is fixedly connected with a bus duct. When a swing plate moves downwards, a limiting block is pulled to move downwards in a moving groove, and meanwhile, a moving rod is driven by the swing plate to slide in a sliding groove; therefore, when the base plate pulls the swing plate to slide downwards, the side wall of the swing plate can be attached to the side wall of the containing groove, thrust is applied to the side wall of the fixing piece, and the fixing piece is extruded and fixed. Due to the fact that the fixing of the bolt needs time, deviation occurs when the bolt is rotationally connected after the fixing piece makes contact with the outer surface of the bolt, the fixing effect on the fixing piece is enhanced, and the locking quality of an internal device after the bus duct is connected with the main body is improved.

Description

Technical Field

[0001] This invention relates to the field of busbar trunking locking technology, specifically a busbar trunking plug-in box locking device. Background Technology

[0002] A busbar trunking plug-in box locking device belongs to the field of power transmission and distribution equipment technology. It aims to solve the problems of cumbersome installation, easy loosening and safety hazards of traditional plug-in boxes. Its core feature is the integration of a mandatory mechanical-electrical interlocking function. Only after the plug-in box is fully locked in place can the internal circuit breaker be closed and energized, which fundamentally prevents the risk of plugging and unplugging under load and accidental detachment. During the use of this device, first open the door of the plug-in box and the protective cover of the busbar trunking to expose the internal connecting pieces. Then move the plug-in box to align the connecting pieces inside with the connecting pieces on the busbar trunking. After that, use bolts to thread-fix the two aligned connecting pieces. When the connecting pieces are placed inside the plug-in box for thread fixing, since the connecting pieces need to move through the outer surface of the bolt after being fitted onto it, the connecting pieces are subject to friction from the connecting blocks inside the plug-in box during movement, causing the connecting pieces to shift during fixing. This affects the fixing effect of the fixing pieces and the locking quality between the busbar trunking and the plug-in box. Summary of the Invention

[0003] The purpose of this invention is to provide a busbar trunking plug-in box locking device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a busbar trunking plug-in box locking device, comprising a main body, with a busbar trunking fixedly connected to the bottom of the main body, and further comprising: A sliding mechanism is installed inside the main body and is used to move when the main body moves. The pushing mechanism is installed on the outer surface of the sliding mechanism and is used to apply thrust to the main body when the sliding mechanism moves.

[0005] Furthermore, the top of the busbar trunking is fixedly connected with several connecting plates, and the main body also includes: The fixing components are installed inside the main body via auxiliary parts. The auxiliary components include a wiring board that is fixedly connected to the inner wall of the main body; The connecting component is installed inside the fixing component and is used to fix the connecting plate.

[0006] Furthermore, the sliding mechanism includes: Telescopic assembly, which is installed inside the fixed assembly, is used to extend or retract when the connecting assembly moves; The movable component is installed at the bottom of the telescopic component and is used to move when the telescopic component moves.

[0007] Furthermore, the promoting organizations include: A swing assembly is mounted on the outer surface of the moving assembly and is used to push the connecting assembly to move.

[0008] Furthermore, the fixing assembly includes several connecting blocks fixedly connected to the side wall of the terminal block, and the top of the connecting blocks is provided with a placement groove; Among them, the bottom of several connecting blocks is fixedly connected to the inner wall of the main body, and the placement groove is a trapezoid with a large opening.

[0009] Furthermore, inclined grooves are provided on the left and right sides of the side wall of the placement slot, and a movable groove is provided on the side of the inclined groove near the wiring board; The entire moving slot is tilted.

[0010] Furthermore, the connecting assembly includes a fixing plate fixedly connected inside the placement slot, and the fixing plate has bolts connected to its internal threads; The bolts penetrate the fixing plate into the interior of the connecting block.

[0011] Furthermore, the telescopic assembly includes several springs fixedly connected to the inner wall of the inclined groove, and a sliding block is fixedly connected to the bottom of the several springs, with a sliding groove opened at the bottom of the sliding block; The sidewall of the sliding block is slidably connected to the inner wall of the inclined groove.

[0012] Furthermore, the movable component includes a movable rod slidably connected inside the sliding groove, and a limit block is fixedly connected to the side wall of the movable rod; The outer surface of the limiting block is slidably connected to the inner wall of the moving groove.

[0013] Furthermore, the swing assembly includes a swing plate rotatably connected to the outer surface of the moving rod, and a push plate is fixedly connected to the side wall of the swing plate; A pad is rotatably connected between the two swing plates, and the side wall of the push plate is inclined.

[0014] The present invention has the following beneficial effects: (1) In this invention, when the swing plate moves downward, it will pull the limiting block to move downward inside the moving groove. At the same time, the moving rod will slide inside the sliding groove under the drive of the swing plate. Thus, while the pad pulls the swing plate to slide downward, the side wall of the swing plate will fit against the side wall of the placement groove, thereby applying a pushing force to the side wall of the fixing plate to squeeze and fix it. This reduces the situation where the fixing plate and the outer surface of the bolt will deviate when the bolt rotates after contacting each other when the fixing plate is fixed inside the connecting block by bolts, due to the time required for bolt fixing. This strengthens the fixing effect of the fixing plate and improves the locking quality of the internal device after the busbar is connected to the main body.

[0015] (2) In this invention, when the bolt moves downward and is fixed to the connecting block by the pad, the spring applies an upward pulling force to the pad, causing the bottom of the fixing plate to be pushed upward. At the same time, the top of the fixing plate is pushed downward by the bolt nut, so that the fixing plate as a whole remains horizontal when it is connected and installed. This reduces the instability of the connection caused by the friction of the side wall of the connecting block when the fixing plate is fixed inside the connecting block by the bolt. It improves the stability of the fixing plate when it moves and improves the locking efficiency of the internal device after the busbar is connected to the main body.

[0016] (3) In this invention, while the sliding block slides downward, the moving rod slides in the direction of the placement groove inside the sliding groove. While the moving rod slides, it pulls the limiting block to slide obliquely downward inside the moving groove. When the swing plate slides obliquely downward, its side wall will drive the push plate to move. When the push plate moves, the two opposing push plates will apply an oblique downward thrust to the fixing plate through the oblique surface, thereby assisting in the correction of the fixing plate during the fixing process, so that the fixing effect of the bolt on the fixing plate is enhanced, and further improving the locking quality of the internal device after the busbar groove is connected to the main body.

[0017] (4) In this invention, when the fixing plate is moved downward and connected to the top of the connecting plate by bolts, if the swing plate does not reach the bottom of the placement groove, the swing plate will be subjected to the reverse force of the spring through the sliding block and fit with the nut of the bolt to adapt to the height of the connecting plate. This reduces the situation where the bolts are over-rotated due to height issues when fixing the fixing plate and the connecting plate by bolts, causing the fixing plate and the top of the connecting plate to fit tightly together. This prevents the connecting plate and the fixing plate from being eroded more during operation and further improves the locking efficiency of the internal device after the busbar trunking is connected to the main body.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 As shown, the present invention is a busbar trunking plug-in box locking device, including a main body 1, with a busbar trunking 101 fixedly connected to the bottom of the main body 1, and further including: The sliding mechanism 2 is installed inside the main body 1 and is used to move when the main body 1 moves; The pushing mechanism 3 is installed on the outer surface of the sliding mechanism 2 and is used to apply a thrust to the main body 1 when the sliding mechanism 2 moves.

[0024] The top of the busbar trunking 101 is fixedly connected with several connecting plates 102, and the main body 1 also includes: Fixing component 11 is installed inside the main body 1 via an auxiliary component; The auxiliary components include a wiring board 111 that is fixedly connected to the inner wall of the main body 1; The connecting component 12 is installed inside the fixing component 11 and is used to fix the connecting plate 102.

[0025] The sliding mechanism 2 includes: Telescopic component 21 is installed inside the fixed component 11 and is used to extend or retract when the connecting component 12 moves; The movable component 22 is installed at the bottom of the telescopic component 21 and is used to move when the telescopic component 21 moves.

[0026] The driving body 3 includes: The swing component 31 is mounted on the outer surface of the moving component 22 and is used to push the connecting component 12 to move.

[0027] The fixing component 11 includes a plurality of connecting blocks 112 fixedly connected to the side wall of the terminal block 111, and the top of the connecting block 112 is provided with a placement groove 113; Among them, the bottom of several connecting blocks 112 is fixedly connected to the inner wall of the main body 1. The placement slot 113 is a trapezoid with a large opening. After the main body 1 is opened, the wiring board 111 and connecting blocks 112 located inside the main body 1 can be seen. When the main body 1 is moved, the connecting blocks 112 will be moved to one side of the connecting plate 102.

[0028] The left and right sides of the side wall of the placement slot 113 are provided with inclined slots 114, and the side of the inclined slot 114 near the wiring board 111 is provided with a movable slot 115. The movable groove 115 is inclined. During the process of placing the fixing piece 121 into the placement groove 113, if the fixing piece 121 is aligned with the bottom of the placement groove 113, the fixing piece 121 will contact the side wall of the placement groove 113.

[0029] The connecting assembly 12 includes a fixing piece 121 fixedly connected inside the placement groove 113, and the fixing piece 121 is internally threaded with a bolt 122; The bolt 122 passes through the fixing plate 121 to the interior of the connecting block 112. When the bolt 122 moves downward and is fixed to the connecting block 112 through the pad 313, the spring 211 applies an upward pulling force to the pad 313, causing the bottom of the fixing plate 121 to be pushed upward. At the same time, the top of the fixing plate 121 is pushed downward by the nut of the bolt 122, so that the fixing plate 121 as a whole remains in a horizontal state during the connection and installation.

[0030] The telescopic component 21 includes a plurality of springs 211 fixedly connected to the inner wall of the inclined groove 114, and a sliding block 212 fixedly connected to the bottom of the plurality of springs 211. A sliding groove 213 is provided at the bottom of the sliding block 212. The side wall of the sliding block 212 is slidably connected to the inner wall of the inclined groove 114. During the process of the pad 313 pulling the swing plate 311 downward, the swing plate 311 will pull the sliding block 212 connected to it to slide downward inside the inclined groove 114 through the moving rod 221. At the same time as the sliding block 212 slides downward, the moving rod 221 will slide inside the sliding groove 213 towards the placement groove 113.

[0031] The movable component 22 includes a movable rod 221 that is slidably connected inside the sliding groove 213, and a limit block 222 is fixedly connected to the side wall of the movable rod 221; The outer surface of the limiting block 222 is slidably connected to the inner wall of the moving groove 115. When the moving rod 221 slides, it will pull the limiting block 222 to slide obliquely downward inside the moving groove 115. When the swing plate 311 slides obliquely downward, its side wall will drive the push plate 312 to move.

[0032] The swing assembly 31 includes a swing plate 311 rotatably connected to the outer surface of the moving rod 221, and a push plate 312 is fixedly connected to the side wall of the swing plate 311. A pad 313 is rotatably connected between the two swing plates 311. The side wall of the push plate 312 is inclined. When the fixing plate 121 is moved downward by the bolt 122 to connect with the top of the connecting plate 102, if the swing plate 311 does not reach the bottom of the placement groove 113, the swing plate 311 will be subjected to the reverse force of the spring 211 through the sliding block 212 and will fit against the nut of the bolt 122 to adapt to the height of the connecting plate 102.

[0033] In use, the operator first opens the protective cover on the busbar trough 101 to expose the connecting plate 102 inside the cover. Then, the door of the main body 1 is opened. After the door of the main body 1 is opened, the wiring plate 111 and the connecting block 112 inside the main body 1 will be seen. When the main body 1 is moved, the connecting block 112 will be moved to one side of the connecting plate 102. Then, the fixing plate 121 is placed into the placement slot 113. When the fixing plate 121 moves to the bottom of the placement slot 113, the bottom of its other end will contact the top of the connecting plate 102. At this time, the bolt 122 is placed into the threaded hole at the top of the fixing plate 121. When the bolt 122 is turned, the fixing plate 121 will be fixedly connected to the connecting block 112 and the connecting plate 102, thereby completing the locking process of the busbar trough 101 plug box.

[0034] When the fixing plate 121 is placed into the placement groove 113, since the pad 313 is located at the bottom of the placement groove 113, the fixing plate 121 will contact the pad 313 as it moves towards the bottom of the placement groove 113. Then, the operator connects the threaded hole on the fixing plate 121 to the threaded hole inside the connecting block 112 using bolt 122. Afterwards, the bolt 122 is rotated. As the bolt 122 rotates and moves towards the inside of the connecting block 112, the nut on the bolt 122 pushes the pad 313 downward through the fixing plate 121. As the pad 313 slides downward, it simultaneously pulls the swing plate 311 downward. As the swing plate 311 moves downward, it pulls the limit block 222. The interior of the groove 115 moves downward, and at the same time, the moving rod 221 slides inside the sliding groove 213 under the drive of the swing plate 311. As the pad 313 pulls the swing plate 311 downward, the side wall of the swing plate 311 will fit against the side wall of the placement groove 113, thereby applying a pushing force to the side wall of the fixing piece 121 and squeezing and fixing it. This reduces the situation where the fixing piece 121 is offset after contacting the outer surface of the bolt 122 when the fixing piece 121 is fixed inside the connecting block 112 by the bolt 122 because the fixing of the bolt 122 requires movement. This strengthens the fixing effect of the fixing piece 121 and improves the locking quality of the internal device after the busbar 101 is connected to the main body 1.

[0035] When the fixing plate 121 is pushed by the nut of bolt 122, causing the pad 313 to move downward, the pad 313 will pull the sliding block 212 downward inside the inclined groove 114 via the swing plate 311. When the sliding block 212 slides, it will pull the spring 211 connected to it to extend and accumulate potential energy. Then, as the nut of bolt 122 continues to push the pad 313 downward through the fixing plate 121, the spring 211 will apply an upward pulling force to both sides of the pad 313 through the sliding block 212 and the swing plate 311, thereby causing the bolt 122 to move downward through the pad 313 and connect to the groove 114. When block 112 is fixed, the spring 211 applies an upward pulling force to the pad 313, causing the bottom of the fixing piece 121 to be pushed upward. At the same time, the top of the fixing piece 121 is pushed downward by the nut of the bolt 122, so that the fixing piece 121 as a whole remains in a horizontal state during connection and installation. This reduces the instability of the connection when the fixing piece 121 is fixed to the inside of the connecting block 112 by the bolt 122 due to the friction of the side wall of the connecting block 112. This improves the stability of the fixing piece 121 during movement and improves the locking efficiency of the internal device after the busbar 101 is connected to the main body 1.

[0036] During the process of the pad 313 pulling the swing plate 311 downward, the swing plate 311 will pull the sliding block 212 connected to it through the moving rod 221 to slide downward inside the inclined groove 114. At the same time as the sliding block 212 slides downward, the moving rod 221 will slide inside the sliding groove 213 towards the placement groove 113. At the same time as the moving rod 221 slides, it will pull the limiting block 222 to slide obliquely downward inside the moving groove 115. When the swing plate 311 slides obliquely downward, its side wall will drive the push plate 312 to move. When the push plate 312 moves, the two opposing push plates 312 will apply an oblique downward thrust to the fixing plate 121 through the inclined surface, thereby assisting in the correction of the fixing plate 121 during the fixing process, which enhances the fixing effect of the bolt 122 on the fixing plate 121 and further improves the locking quality of the internal device after the busbar 101 is connected to the main body 1.

[0037] During the process of placing the fixing plate 121 into the placement groove 113, if the fixing plate 121 is aligned with the bottom of the placement groove 113, it will contact the side wall of the placement groove 113. Guided by the side wall, it will gradually move towards the bottom of the placement groove 113, thus contacting the top of the swing plate 311. Then, when the fixing plate 121 is moved downwards by the bolt 122 to connect with the top of the connecting plate 102, if the swing plate 311 has not reached the bottom of the placement groove 113, the swing plate 311... The spring 211, through the sliding block 212, acts as a counterforce to the bolt 122, thus fitting the nut of the bolt 122 to adapt to the height of the connecting plate 102. This reduces the possibility of the bolt 122 over-rotating due to height issues when fixing the fixing plate 121 to the connecting plate 102 with the bolt 122, causing the fixing plate 121 to fit tightly against the top of the connecting plate 102. This prevents the connecting plate 102 and the fixing plate 121 from being further eroded during operation, and further improves the locking efficiency of the internal device after the busbar 101 is connected to the main body 1.
