Description

Technical Field

[0001] This invention belongs to the field of busbar technology, and specifically relates to a general-purpose busbar. Background Technology

[0002] Busbar trunking is a busbar system consisting of a metal plate as a protective shell, conductive bars, insulating materials, and related accessories. It can be made into a plug-in type enclosed busbar with plug-in junction boxes at intervals, or into a feeder type enclosed busbar without junction boxes in the middle. In the power supply system of high-rise buildings, power and lighting lines are often set up separately, and busbar trunking is installed vertically along the wall in the electrical shaft as the main power supply line, one or more times.

[0003] During the operation of busbar trunking, it is usually necessary to connect the assemblies of two adjacent busbar trunkings to ensure overall conductivity. After connecting the copper busbars of adjacent busbar trunkings, a box must be installed at the connection point of the copper busbars of the busbar trunking for protection. The boxes are usually connected by bolts. However, the busbar trunking will vibrate during operation, causing the bolt connection to become unstable, resulting in more serious problems. Moreover, bolt connection requires tools, which is inconvenient for assembly. Therefore, a universal busbar trunking is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: how to design a bolt that can ensure that it will not become loose due to accidents during long-term use and to ensure that the bolt is easy to assemble.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a universal busbar trunking, comprising a busbar trunking body, a protective cover slidably mounted on one side of the busbar trunking body, a rectangular baffle adapted to the protective cover mounted on the outer side of the busbar trunking body, a connecting frame one fixedly connected to the side of the protective cover away from the busbar trunking body, a connecting frame two fixedly connected to the other side of the busbar trunking body, copper busbars protruding from both sides mounted in the busbar trunking body, side plates mounted on both the front and rear sides of the busbar trunking body, and tightening plates mounted on the two side plates on one side, and the front and rear sides... An intermediate conductive plate is installed between each of the two adjacent copper busbars. A tightening post is installed through the middle of the tightening plate and the intermediate conductive plate. A tightening nut is threaded onto the other side of the tightening post. A rectangular blocking strip is installed on the side of the first connecting frame close to the second connecting frame. A rectangular silicone strip is installed around the outer ring of the rectangular blocking strip. Connecting components are installed at the four corners of the first connecting frame. A limiting component is installed on the side of the connecting component on the first connecting frame. Preliminary connecting parts are installed on both sides of the rectangular blocking strip. An assembly cavity adapted to the rectangular blocking strip is installed on the inner wall of the second connecting frame.

[0007] By adopting the above technical solution, when connecting a pair of adjacent busbar trunking bodies, the intermediate conductive plates are spaced apart between adjacent copper busbars, and a tightening post is installed between the two sets of opposing copper busbars. Through the passage of the tightening post, the tightening nut is tightened onto the tightening post. The tightening post drives the two opposing tightening plates to approach each other, which can tighten the copper busbars and the intermediate conductive plates, ensuring stability. Furthermore, the protective cover is placed over the connection point of the pair of busbar trunking bodies to ensure isolation at the connection point. The protective cover and the first connecting frame are driven to move towards the second connecting frame. In this way, the connecting components allow the first connecting frame and the second connecting frame to be quickly connected without the need for other tools. Moreover, during long-term use, it can completely prevent problems caused by loosening of fasteners, ensuring a firm connection.

[0008] Furthermore, the connecting assembly includes a rotating cavity mounted on the first connecting frame, with a receiving cavity at the bottom of the rotating cavity. The first connecting frame also has a threaded interface first that communicates with the rotating cavity. A bolt is inserted through the threaded interface first, and a cross cavity is provided at the head of the bolt. A recovery support sleeve is provided at the bottom of the receiving cavity. A recovery liner is provided at the connection between the opening of the receiving cavity and the rotating cavity. Several strip-shaped cavities are arranged in a ring shape on the inner wall of the threaded interface first near the head. Recovery strips are fixed in the strip-shaped cavities. The second connecting frame is reserved on one side adjacent to the first connecting frame.

[0009] By adopting the above technical solution and utilizing the connecting components, during the connection of adjacent busbar trunking bodies, the copper busbars are first connected. Then, the protective cover is driven to move the first connecting frame, which then mates with the adjacent side of the second connecting frame. At this moment, the initial connection ensures the connection between the second connecting frame and the first connecting frame, ensuring that the connecting components cannot be separated during operation, thus improving assembly efficiency. Initially, the cross magnetic block is inserted into the cross cavity due to the spiral beryllium copper wire, releasing the restriction of the locking component. Then, by rotating the connecting strip and the support strip, the first hollow cylinder is driven to rotate, which in turn drives the second hollow cylinder to rotate, driving the cross magnetic block to rotate. This causes the cross magnetic block to drive the bolt to rotate, so that the bolt is screwed from the first thread interface into the second thread interface. This connects the first connecting frame and the second connecting frame. During continuous screwing, the head of the bolt will gradually penetrate deeper into the rotating mechanism. In the cavity, pressure is applied to the recovery support sleeve and the recovery liner. After tightening to the correct position, the bolt securely connects the first and second connecting frames, thereby securely connecting the two busbar trunking bodies. During long-term use, the bolt head presses against the recovery support sleeve during assembly, causing the central area of ​​the recovery support sleeve to tighten inward. The recovery support sleeve also presses against the recovery liner. Due to the recovery characteristic of the recovery support sleeve itself, and in conjunction with the recovery liner, a force is generated towards the bolt, pushing the bolt outward and making the threaded connection at the threaded joint tighter. After the bolt is screwed into the threaded interface, it will change shape with the recovery strip. The recovery strip is located between the bolt and the strip cavity, tightening the bolt and filling the gap between the bolt and the threaded interface, ensuring the reliability of the bolt assembly. This ensures that the bolt connection is secure and will not loosen over a long period of time.

[0010] Furthermore, one side of the bolt protruding into the second thread interface is connected to the second thread interface and the first thread interface, the head of the bolt is in the rotating cavity, and the orientation of the second thread interface corresponds to that of the first thread interface.

[0011] By adopting the above technical solution, the bolt is inserted into the thread interface one and the thread interface two, which ensures the connection between the connecting frame one and the connecting frame two. The bolt is in the rotating cavity, which allows the bolt to apply pressure to the restoration support sleeve and the restoration liner.

[0012] Furthermore, the restoring liner is located between the restoring support sleeve and the bottom of the rotating cavity. The restoring support sleeve includes a support side and a support piece. The support side extends beyond the bottom of the receiving cavity and is located on one side of the receiving cavity, connected to the bottom of the receiving cavity. The support piece is installed on the other side of the support side. The opening in the middle of the support piece is compatible with the thread interface. The side of the support side is recessed inward in a C-shape.

[0013] By adopting the above technical solution, the orientation of the restoring liner can withstand the pressure of the bolt. With the installation of the restoring support sleeve, after bearing the pressure of the bolt, it can form an opposite counterforce with the restoring properties of the restoring liner. After the bolt is assembled, it can abut against the head of the bolt, making the connection between the bolt and the thread of the thread interface more secure.

[0014] Furthermore, one of the centrally located sides of the recovery strip near the filament interface protrudes beyond the strip cavity.

[0015] By adopting the above technical solution, after the recovery strip is assembled at the thread interface, it will form a compression towards the bolt, which can help to tighten the bolt and fill the gap between the thread interface and the bolt, thus strengthening the reliability of the assembly.

[0016] Furthermore, the limiting component includes a circular track rotatably connected to the connecting frame one. Two support strips are mounted on one side of the circular track, and a connecting strip is mounted on the other side of the two support strips. A hollow cylinder one is fixed to the side of the connecting strip facing the connecting frame one. A hollow cylinder two is slidably connected to the outer side of the hollow cylinder one. A support ring is mounted on the outer circumference of the hollow cylinder two near the end of the hollow cylinder one. A spiral beryllium copper wire one is installed between the support ring and the connecting strip. A cross magnetic block is fixed to the side of the hollow cylinder two near the connecting frame one. A pressure bar is mounted on one side of the cross magnetic block, and a blocking strip is mounted on the other side of the pressure bar. A locking component for locking the circular track is installed on the side of the connecting frame one.

[0017] By adopting the above technical solution, after the first connecting frame and the second connecting frame are attached, the locking component on the circular track is released. The first hollow cylinder can be driven to rotate by rotating the support strip and the connecting strip, which in turn drives the second hollow cylinder to rotate. The rotation of the second hollow cylinder drives the cross magnetic block inserted into the cross cavity to rotate, allowing the bolt to be screwed from the thread interface one into the thread interface two, ensuring a stable connection. During this period, the spiral beryllium copper wire one will continuously apply pressure to the support ring, thereby keeping the cross magnetic block driven by the second hollow cylinder in the cross cavity, ensuring that the bolt will not loosen at will, and ensuring a stable connection between the first connecting frame and the second connecting frame.

[0018] Furthermore, a rotating track groove adapted to the circular track is installed on the wall surface of the first connecting frame. The pressure bar protrudes from the connecting strip through the second hollow cylinder and the first hollow cylinder. A guide bar that slides and connects with the inner wall of the second hollow cylinder is installed on the outer side of the first hollow cylinder.

[0019] By adopting the above technical solution, the hollow cylinder 2 can slide on the hollow cylinder 1 while rotating with the hollow cylinder 1 through the installation of the guide bar. The rotating track groove restricts the circular track to ensure smooth rotation. During the separation of the connecting frame 1 and the connecting frame 2, the pressure bar can drive the hollow cylinder 2 and the cross magnetic block to abut in the cross cavity of the bolt by applying pressure to the blocking bar. This ensures that it will not separate from the bolt when it is unscrewed, and no additional tools are required, ensuring efficiency and convenience.

[0020] Furthermore, the positioning component includes a fixing piece fixed to the connecting frame, a T-shaped displacement bar slidingly passing through the fixing piece, and a spiral beryllium copper wire II installed between the T-shaped displacement bar and the fixing piece.

[0021] By adopting the above technical solution, the locking component can restrict and lock the circular track, thereby restricting and locking the entire system and ensuring reliability during long-term use.

[0022] Furthermore, a bayonet adapted to the T-shaped displacement bar is installed on the outer side of the circular track.

[0023] By adopting the above technical solution, the bayonet can be adapted to the T-shaped displacement bar to lock the rotation of the circular track.

[0024] Furthermore, the preliminary connection includes a receiving cavity installed on a rectangular stop bar. The length of the receiving cavity is half the length of the rectangular stop bar. A blocking plate is rotatably connected in the receiving cavity. The blocking plate is hook-shaped on one side near the second connecting frame. Several resistance strips are installed on the hook-shaped surface of the blocking plate. A locking cavity adapted to the orientation of the blocking plate is installed on the second connecting frame. A metal spring is installed between the blocking plate and the cavity wall of the receiving cavity.

[0025] By adopting the above technical solution, during the initial fitting of the first and second connecting frames, the obstruction piece will be inserted into the assembly cavity of the second connecting frame along with the rectangular plug. The obstruction piece will initially retract into the receiving cavity. When it is in the position of the locking cavity, the metal spring will drive the obstruction piece to be inserted into the locking cavity. This will apply a force to the side, ensuring that the first and second connecting frames cannot be separated arbitrarily during the bolt assembly. The rectangular silicone strip ensures the sealing performance of the connection.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention, through the cooperation of connecting components and limiting components, can connect adjacent busbar trunking bodies without additional tools. Rotating the connecting strip and supporting strip can drive the cross magnetic block to rotate the bolt, so that the bolt can be screwed from thread interface one into thread interface two, eliminating the cumbersome process of carrying and operating traditional tools and improving assembly efficiency.

[0028] 2. When the obstruction piece of the preliminary connection part of the present invention is inserted into the assembly cavity of the second connection frame in a rectangular shape, it will be locked into the positioning cavity under the action of the metal spring piece, providing a stable foundation for the subsequent operation of the connection components, avoiding the arbitrary separation of the first connection frame and the second connection frame when the bolt assembly is not completed, and ensuring a continuous and smooth assembly process.

[0029] 3. The bolt head of the present invention presses against the recovery support sleeve and the recovery liner. The two, by virtue of their own recovery characteristics, generate an outward force against the bolt, making the connection between the bolt and the threaded interface closer. The recovery strip fills the gap between the bolt and the threaded interface and squeezes the bolt, further enhancing the stability of the bolt after assembly and effectively avoiding problems caused by fastener loosening during long-term use.

[0030] 4. The rectangular silicone strip on the outer rectangular ring of the first connecting frame of the present invention can fill the gap when the first connecting frame and the second connecting frame are attached, enhance the sealing of the connection, and further prevent the intrusion of harmful substances from the outside. The pressure bar passes through the second hollow cylinder and the first hollow cylinder protrudes from the connecting strip. When separating the first connecting frame and the second connecting frame, applying pressure to the blocking strip can keep the cross magnetic block in contact with the cross cavity of the bolt, ensuring that it does not separate when the bolt is unscrewed.

[0050] Reference Figures 1-11 This invention proposes a universal busbar trunking system, comprising a busbar trunking body 1, a protective cover 2 slidably mounted on one side of the busbar trunking body 1, a rectangular baffle 14 adapted to the protective cover 2 mounted on the outer side of the busbar trunking body 1, a connecting frame 3 fixedly connected to the side of the protective cover 2 away from the busbar trunking body 1, and a connecting frame 4 fixedly connected to the other side of the busbar trunking body 1. Copper busbars 5 protruding from both sides are installed in the busbar trunking body 1, and copper busbars 5 are installed on both the front and rear sides of the busbar trunking body 1. On the side plate 6, tightening plates 7 are installed on both side plates 6 located on one side. Intermediate conductive plates 10 are installed between two adjacent copper busbars 5. A tightening post 8 is installed through the middle of the tightening plate 7 and the intermediate conductive plate 10. A tightening nut 9 is threaded onto the other side of the tightening post 8. A rectangular blocking strip 12 is installed on the side of the connecting frame 1 3 near the connecting frame 2 4. A rectangular silicone strip 13 is installed around the outer ring of the rectangular blocking strip 12. Connecting components are installed at the four corners of the connecting frame 1 3. A limiting component is installed on the side of the component on the connecting frame 1 3. Preliminary connecting parts are installed on both sides of the rectangular plug 12. An assembly cavity adapted to the rectangular plug 12 is installed on the inner wall of the connecting frame 2 4. When connecting a pair of adjacent busbar trunking bodies 1, the intermediate conductive sheet 10 is spaced between adjacent copper busbars 5, and a tightening post 8 is installed between the two opposing sets of copper busbars 5. Through the passage of the tightening post 8, the tightening nut 9 is tightened onto the tightening post 8. The tightening post 8 drives the two opposing installed... The tightening plates 7 approach each other, which can tighten the copper busbar 5 and the intermediate conductive plate 10 to ensure stability. They are also covered by the protective cover 2 at the connection of the two busbar trunking bodies 1 to ensure isolation at the connection. The protective cover 2 and the first connecting frame 3 are driven to move towards the second connecting frame 4. In this way, the connecting components allow the first connecting frame 3 and the second connecting frame 4 to be quickly connected without the need for other tools. During long-term use, it can completely prevent problems caused by the loosening of fasteners and ensure a firm connection.

[0051] The connecting assembly includes a rotating cavity 111 mounted on the connecting frame 3. A receiving cavity 115 is mounted at the bottom of the rotating cavity 111. A threaded interface 117 communicating with the rotating cavity 111 is also mounted in the connecting frame 3. A bolt 112 is inserted through the threaded interface 117, and a cross cavity 113 is mounted on the head of the bolt 112. A recovery support sleeve 119 is mounted at the bottom of the receiving cavity 115. A recovery liner 1110 is mounted at the opening of the receiving cavity 115 and the rotating cavity 111. Several strip-shaped cavities 114 are arranged in a ring shape on the inner wall of the threaded interface 117 near the head. Recovery strips 116 are fixedly connected to the strip-shaped cavities 114. A threaded interface 118 is reserved on one side of the connecting frame 4 adjacent to the connecting frame 3. Using the connecting assembly, during the connection of adjacent busbar trunking bodies 1, the copper busbars 5 are first connected. Then, the protective cover 2 is driven to move the connecting frame 3, which then mates with the adjacent side of the connecting frame 4. At this moment, the initial connection ensures the connection between the connecting frame 4 and the connecting frame 3, ensuring that they cannot be separated during the operation of the connecting assembly, thus affecting the assembly efficiency. Initially, the cross magnetic block 106 is inserted into the cross cavity 113 due to the spiral beryllium copper wire 108, releasing the restriction of the locking assembly. Then, by rotating the connecting strip 103 and the supporting strip 102, the hollow cylinder 104 is driven to rotate, which in turn drives the hollow cylinder 2 105 to rotate, driving the cross magnetic block 106 to rotate, thus driving the cross magnetic block 106 to rotate. Bolt 112 is rotated, causing it to screw from threaded interface 117 into threaded interface 118. This connects connecting frame 3 and connecting frame 4. During continuous rotation, the head of bolt 112 gradually penetrates into the rotating cavity 111, applying pressure to the restoring support sleeve 119 and the restoring liner 1110. After being fully rotated, bolt 112 securely connects connecting frame 3 and connecting frame 4, thereby securely connecting the two busbar trunking bodies 1. During long-term use, the head of bolt 112 presses against the restoring support sleeve 119 during assembly, causing the central area of ​​the periphery of the restoring support sleeve 119 to tighten inwards. The restoring support sleeve 119 also presses against the restoring liner 1110. The original support sleeve 119 has a self-recoverable characteristic, and together with the recovery liner 1110, the recovery support sleeve 119, the recovery liner 1110, the recovery strip 116, and the rectangular silicone strip 13 are all made of rubber. This can generate a force towards the bolt 112, pushing the bolt 112 outward to make the thread connection at the thread joint tighter. After the bolt 112 is screwed into the thread interface 117, it will change shape with the recovery strip 116. The recovery strip 116 is located between the bolt 112 and the strip cavity 114, tightening the bolt 112 and filling the gap between the bolt 112 and the thread interface 117, ensuring the reliability of the bolt 112 after assembly. This can ensure that the bolt 112 connection is reliable and cannot loosen for a long time.

[0052] Bolt 112 is inserted into one side of threaded interface 118 and threaded interface 117. The head of bolt 112 is in the rotating cavity 111. The orientation of threaded interface 118 corresponds to threaded interface 117. By inserting bolt 112 into threaded interface 117 and threaded interface 118, the connection between connecting frame 3 and connecting frame 4 can be ensured. Bolt 112 is in the rotating cavity 111, which allows bolt 112 to apply pressure to the restoring support sleeve 119 and the restoring liner 1110.

[0053] The restoration liner 1110 is located between the restoration support sleeve 119 and the bottom of the rotating cavity 111. The restoration support sleeve 119 includes a support side 1191 and a support piece 1192. The support side 1191 extends beyond the bottom of the receiving cavity 115 and is connected to the bottom of the receiving cavity 115 on one side. The support piece 1192 is installed on the other side of the support side 1191. The opening in the center of the support piece 1192 is connected to the thread interface 11. 7. They are mutually compatible. The side of the supporting side 1191 is concave inward in a C-shape. The position of the restoring liner 1110 can withstand the pressure of the bolt 112. With the installation of the restoring support sleeve 119, after bearing the pressure of the bolt 112, it can form an opposite counterforce with the restoring property of the restoring liner 1110. After the bolt 112 is assembled, it can abut against the head of the bolt 112, so that the connection between the bolt 112 and the threaded part of the threaded interface 117 is closer and more secure.

[0054] The recovery strip 116 protrudes beyond the strip cavity 114 near the center of the thread interface 117. After the thread interface 117 is assembled, the recovery strip 116 will form a compression towards the bolt 112, which can help to tighten the bolt 112 and fill the gap between the thread interface 117 and the bolt 112, thus strengthening the assembly.

[0055] The limiting component includes a circular track 101 rotatably connected to the connecting frame 3. Two support bars 102 are mounted on one side of the circular track 101, and a connecting bar 103 is mounted on the other side of the two support bars 102. A hollow cylinder 104 is fixed to the side of the connecting bar 103 facing the connecting frame 3. A hollow cylinder 105 is slidably connected to the outer side of the hollow cylinder 104. A support ring 107 is mounted on the outer circumference of the hollow cylinder 105 near the end of the hollow cylinder 105. A spiral beryllium copper wire 108 is installed between the support ring 107 and the connecting bar 103. A cross-shaped magnetic block 106 is fixed to the side of the hollow cylinder 105 near the connecting frame 3. A pressure rod 109 is mounted on one side of the cross-shaped magnetic block 106, and a blocking bar 1010 is mounted on the other side of the pressure rod 109. A locking component is installed on the side of the first frame 3 to lock the circular track 101. After the first frame 3 and the second frame 4 are attached, the locking component on the circular track 101 is released. The first hollow cylinder 104 can be driven by rotating the support bar 102 and the connecting bar 103, which in turn drives the second hollow cylinder 105 to rotate. The rotation of the second hollow cylinder 105 drives the cross magnetic block 106 protruding into the cross cavity 113 to rotate, so that the bolt 112 is screwed from the thread interface 117 into the thread interface 118, ensuring a stable connection. During this period, the spiral beryllium copper wire 108 will continuously apply pressure to the support ring 107, so that the second hollow cylinder 105 drives the cross magnetic block 106 to always be locked in the cross cavity 113, ensuring that the bolt 112 will not loosen at will, and ensuring a stable connection between the first frame 3 and the second frame 4.

[0056] A rotating track groove adapted to the circular track 101 is installed on the wall of the connecting frame 13. The pressure bar 109 protrudes from the connecting bar 103 through the hollow cylinder 2 105 and the hollow cylinder 1 104. A guide bar is installed on the outside of the hollow cylinder 1 104 and slides on the inner wall of the hollow cylinder 2 105. The installation of the guide bar allows the hollow cylinder 2 105 to slide on the hollow cylinder 1 104 while rotating with it. The rotating track groove restricts the circular track 101 to ensure smooth rotation. During the separation of the connecting frame 13 and the connecting frame 2 4, the pressure bar 109 can drive the hollow cylinder 2 105 and the cross magnetic block 106 to abut in the cross cavity 113 of the bolt 112 by applying pressure to the blocking bar 1010. This ensures that the bolt 112 will not separate when it is unscrewed, and no additional tools are required, ensuring efficiency and convenience.

[0057] The positioning component includes a fixing piece 1011 fixed to the connecting frame 3. A T-shaped displacement rod 1012 slides through the fixing piece 1011. A spiral beryllium copper wire 1013 is installed between the T-shaped displacement rod 1012 and the fixing piece 1011. The positioning component can restrict and position the circular track 101, thereby restricting and positioning the whole, ensuring reliability during long-term use.

[0058] The outer side of the circular track 101 is equipped with a bayonet that is compatible with the T-shaped displacement bar 1012. The bayonet can be used to fit the T-shaped displacement bar 1012 and lock the rotation of the circular track 101.

[0059] The preliminary connection includes a receiving cavity 151 mounted on a rectangular plug 12. The length of the receiving cavity 151 is half the length of the rectangular plug 12. A blocking piece 152 is rotatably connected to the receiving cavity 151. The blocking piece 152 is hook-shaped near the connecting frame 4, and several resistance strips are mounted on the hook-shaped surface of the blocking piece 152. A locking cavity 156 adapted to the orientation of the blocking piece 152 is mounted on the connecting frame 4. A metal spring 153 is installed between the blocking piece 152 and the cavity wall of the receiving cavity 151. During the initial fitting of the first connecting frame 3 and the second connecting frame 4, the obstruction piece 152 will be inserted into the assembly cavity of the second connecting frame 4 along with the rectangular plug 12. The obstruction piece 152 will initially retract into the receiving cavity 151. When it is in the position of the locking cavity 156, the metal spring piece 153 drives the obstruction piece 152 to be inserted into the locking cavity 156. This can apply a force towards the side to ensure that the first connecting frame 3 and the second connecting frame 4 cannot be separated arbitrarily during the assembly of the bolts 112. The rectangular silicone strip 13 ensures the sealing performance of the connection.

[0060] The specific implementation method is as follows: When connecting the two busbar trunking bodies 1, firstly, the intermediate conductive plates 10 are installed at intervals between adjacent copper busbars 5, passing through the tightening post 8. The tightening nut 9 is tightened onto the tightening post 8. The tightening post 8 drives the two opposing tightening plates 7 to approach each other, allowing the copper busbars 5 and the intermediate conductive plates 10 to be tightened, ensuring a stable connection. Then, the protective cover 2 and the first connecting frame 3 are driven to move towards the second connecting frame 4, thus completing the connection. When frame 1 3 and connecting frame 2 4 are about to fit together, the obstruction piece 152 will be inserted into the assembly cavity of connecting frame 2 4 along with the rectangular plug 12. The obstruction piece 152 will initially be retracted into the receiving cavity 151. When it is in the position of the locking cavity 156, the metal spring piece 153 drives the obstruction piece 152 to be inserted into the locking cavity 156. This can apply a force to the side, ensuring that connecting frame 1 3 and connecting frame 2 4 cannot be separated arbitrarily during the assembly of the bolts 112.

[0061] Then, the T-shaped displacement bar 1012 is driven to separate from the bayonet on the circular track 101. Rotating the connecting bar 103 and the supporting bar 102 drives the rotation of the hollow cylinder 104, which in turn drives the rotation of the hollow cylinder 105, driving the cross magnetic block 106 to rotate. The cross magnetic block 106 then drives the bolt 112 to rotate, causing the bolt 112 to be screwed from the thread interface 117 into the thread interface 118. This connects the connecting frame 3 and the connecting frame 4, and during the continuous screwing period... During this process, the head of bolt 112 gradually penetrates into the rotating cavity 111, then applies pressure to the restoring support sleeve 119 and the restoring liner 1110. After being tightened to the correct position, bolt 112 securely connects connecting frame 1 3 and connecting frame 2 4, thereby securely connecting the two busbar trunking bodies 1. Furthermore, during long-term use, because the head of bolt 112 presses against the restoring support sleeve 119 during assembly, the central area of ​​the periphery of the restoring support sleeve 119 tightens inwards, and the restoring... The support sleeve 119 presses against the recovery liner 1110. Due to the recovery characteristic of the support sleeve 119 itself, and in conjunction with the recovery liner 1110, this generates a force towards the bolt 112, pushing the bolt 112 outwards and making the thread connection at the threaded joint tighter. Furthermore, after the bolt 112 is screwed into the threaded interface 117, it will change shape with the recovery strip 116. The recovery strip 116 is positioned between the bolt 112 and the strip-shaped cavity 114, tightening the bolt 112. 12. Fill the gap between bolt 112 and threaded interface 117 to ensure the bolt 112 is secure after assembly. This ensures that the bolt 112 connection is secure and will not loosen over a long period of time. During this period, the spiral beryllium copper wire 108 will continuously apply pressure to the support ring 107, thereby causing the hollow cylinder 105 to drive the cross magnetic block 106 to always be stuck in the cross cavity 113, ensuring that the bolt 112 will not loosen at will, and ensuring the stability of the connection between the connecting frame 3 and the connecting frame 4.
