The output end of the plug is electrically connected to a plug.

[0010] Optionally, the connector includes a second insulating partition, and the second insulating partition is provided with abutting conductive pieces on both sides near the power transmission part.

[0014] Compared with the prior art, the present invention has the following advantages and technical effects:

Simultaneously, the invention forms a power-collecting channel through two spaced-apart power transmission sections within the same insulating sleeve. This channel is connected to the external space, facilitating the insertion of a power-collecting device into the channel to contact the two power transmission sections. Furthermore, since the two power transmission sections have opposite polarities, they can be connected to the electrical circuit of the power-consuming equipment via the power-collecting device, ensuring the completion of power collection. Furthermore, the power extraction channel in this invention extends in the same direction as the busbar body and is connected to the external space, making it convenient to install the power extraction device at different locations on the busbar body. In addition, this invention detachably connects adjacent busbar bodies through body connectors and electrically connects the corresponding power transmission parts in adjacent busbar bodies through power transmission part connectors, ensuring that the corresponding power transmission parts in adjacent busbar bodies are in an electrically conductive state. This allows the power extraction device to be plugged into the power extraction channel at any location on the busbar body to complete the power extraction work without needing to rearrange the workshop's power distribution system, thus adapting to situations such as the addition, reduction, or relocation of workshop equipment.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Referring to the accompanying drawings, the present invention provides a power transmission bus, including a bus body 1 and an end connection assembly; the bus body 1 is provided with several sets, and a number of conductive cavities 11 are provided inside the bus body 1. An insulating sheath 12 is detachably connected to the conductive cavity 11, and a power transmission section 13 is detachably connected to the insulating sheath 12 and arranged oppositely and at intervals. A power extraction channel 14 is provided between two power transmission sections 13 arranged at intervals. The power extraction channel 14 extends in the same direction as the bus body 1 and is connected to the external space. The two power transmission sections 13 in the same conductive cavity 11 have opposite polarities; the end connection assembly includes a body connector and a power transmission section connector. Adjacent bus bodies 1 are detachably connected through the body connector, and the power transmission sections 13 arranged correspondingly in adjacent bus bodies 1 are electrically connected through the power transmission section connector.

[0040] When the present invention is in operation, the insulating sleeve 12 insulates the power transmission section 13 from the busbar body 1, and the insulating sleeve 12 detachably connects the power transmission section 13 to the conductive cavity 11 of the busbar body 1, thereby realizing the connection between the power transmission section 13 and the busbar body 1. At the same time, the present invention forms a power extraction channel 14 through two spaced power transmission sections 13 arranged in the same insulating sleeve 12. The power extraction channel 14 is connected to the external space, which facilitates the insertion of the power extraction device into the power extraction channel 14 and abutting against the two power transmission sections 13. Since the two power transmission sections 13 have opposite polarities, the two power transmission sections 13 can be connected to the electrical circuit of the electrical equipment through the power extraction device, ensuring the completion of the power extraction work. Furthermore, the power supply channel 14 in this invention extends in the same direction as the busbar body 1, which facilitates the power supply device to draw power at different locations on the busbar body 1. In addition, this invention detachably connects adjacent busbar bodies 1 through body connectors and electrically connects the corresponding power transmission parts 13 in adjacent busbar bodies 1 through power transmission part connectors, ensuring that the corresponding power transmission parts 13 in adjacent busbar bodies 1 are in an electrically conductive state. This allows the power supply device to be plugged into the power supply channel 14 at any location on the busbar body 1 to complete the power supply operation without the need to rearrange the workshop's power distribution system, thus adapting to situations such as the addition, reduction, or relocation of workshop equipment.

[0041] In this embodiment, the power transmission section connector can be implemented using various methods such as conductive wire connection and conductive plate connection. Preferably, a first insulating partition 21 is provided between adjacent power transmission sections 13 on the side near the end connection assembly. The power transmission section connector includes a power transmission clamp 22, which is disposed between the first insulating partition 21 and the power transmission section 13, and both ends of the power transmission clamp 22 abut against the corresponding power transmission section 13 in the adjacent busbar body 1. In this embodiment, the power transmission section connector uses the power transmission clamp 22 for power transmission. One power transmission clamp 22 is provided on each side of each power transmission section 13, and the adjacent power transmission clamps 22 are insulated by the first insulating partition 21, ensuring that the corresponding power transmission sections 13 in the adjacent busbar body 1 are in a conductive state, but adjacent power transmission sections 13 in the same busbar body 1 are in an insulated state.

[0042] In a further optimized design, the main body connector includes a first clamping plate 23 and a second clamping plate 24. The first clamping plate 23 and the second clamping plate 24 are respectively located on both sides of the busbar body 1 near the end connection assembly. Both the first clamping plate 23 and the second clamping plate 24 are detachably connected to the adjacent busbar body 1. The first clamping plate 23, the second clamping plate 24, the power transmission section 13, the first insulating partition 21, and the power transmission clamping plate 22 are parallel to each other and fastened together by bolts and nuts. In this embodiment, the power transmission section 13, the first insulating partition 21, and the power transmission clamping plate 22 are connected together using the first clamping plate 23, the second clamping plate 24, and the bolts and nuts. Both ends of the first clamping plate 23 are detachably connected to the adjacent busbar body 1, and both ends of the second clamping plate 24 are detachably connected to the adjacent busbar body 1, thereby achieving a detachable connection between adjacent busbar bodies 1 and an electrical connection between the corresponding power transmission sections 13 within adjacent busbar bodies 1.

[0043] In this embodiment, the first clamping plate 23, the second clamping plate 24, the first insulating partition 21, and the power transmission clamping plate 22 are all provided with through holes at corresponding positions in the middle, and these through holes are located between the power transmission sections 13 correspondingly arranged within adjacent busbar bodies 1. The bolts and nuts include bolts 25 and nuts 26. An insulating sleeve 27 is fitted on the outside of the bolt 25. The bolt 25 and the insulating sleeve 27 pass through the corresponding through holes. The two ends of the bolt 25 are fastened by the nuts 26. That is, by rotating the nuts 26, a compressive force is applied to the first clamping plate 23 and the second clamping plate 24, thereby connecting the first clamping plate 23, the second clamping plate 24, the power transmission section 13, the first insulating partition 21, and the power transmission clamping plate 22 together. In some embodiments, the first clamping plate 23 and the second clamping plate 24 are C-shaped structures. The two side wings of the first clamping plate 23 and the two side wings of the second clamping plate 24 are correspondingly arranged, and the corresponding side wings are detachably connected with the first plate and the second plate. The first plate and the second plate are arranged on the other two sides of the assembly (transmission part 13, first insulating partition 21 and transmission clamping plate 22). The first clamping plate 23, the second clamping plate 24, the first plate and the second plate are enclosed to form a complete shell. The shell surrounds the assembly (transmission part 13, first insulating partition 21 and transmission clamping plate 22), leaving only two ports to ensure that the end of the busbar body 1 is inserted into the shell.

[0044] In this embodiment, the busbar body 1 is divided into a straight busbar body and a bent busbar body. The straight busbar body has a straight structure, and the bent busbar body has a bent structure. That is, the bent busbar body includes two fixedly connected separate busbar bodies, which are arranged at a certain angle. Preferably, the angle between the two separate busbar bodies is 90 degrees, that is, the two separate busbar bodies are arranged perpendicularly to achieve the turning of the transmission busbar. By combining the straight busbar body, the bent busbar body, and the end connection components, a complete transmission busbar is formed, which can adapt to workshops or other application spaces with different structures.

[0045] In a further optimized design, a sealing plate 15 is detachably connected to the side of the busbar body 1 where the power intake channel 14 is connected to the external space. An insulating support 151 is provided at the end of the sealing plate 15 near the power intake channel 14, and the insulating support 151 is engaged with the power intake channel 14. This invention uses the sealing plate 15 to separate the power intake channel 14 from the external space, thus providing a sealing effect. Simultaneously, the insulating support 151 in the sealing plate 15 engages with the power intake channel 14, supporting the power transmission section 13 within the same busbar body 1. This further ensures that the power transmission sections 13 are spaced apart and prevents them from falling out of the insulating sleeve 12 during transportation.

[0046] Preferably, the insulating support 151 adopts an arrow-shaped structure, that is, the insulating support 151 includes a support plate fixedly connected to the sealing plate 15, and the support plate is arranged perpendicular to the sealing plate. Two abutment plates are fixedly provided on the side of the support plate away from the sealing plate 15, and the two abutment plates are respectively in contact with the power transmission part 13. The arrow-shaped insulating support 151 can be easily inserted into the power extraction channel 14, and at the same time, it can be used to check whether the power transmission part 13 is installed in the corresponding position.

[0047] In a further optimized design, the transmission section 13 is a copper busbar, and the insulating sleeve 12 has grooves for accommodating the copper busbar. Copper has excellent conductivity, and in this embodiment, a copper busbar is used as the transmission section 13. The grooves on the insulating sleeve 12 are used to restrict the position of the copper busbar. Preferably, the busbar body 1 has multiple snap-fit ​​plates fixedly installed inside the conductive cavity 11 and at its ends. The insulating sleeve has grooves or protrusions that match the snap-fit ​​plates. This snap-fit ​​relationship enables a detachable connection between the conductive cavity 11 and the insulating sleeve 12. In this embodiment, the snap-fit ​​relationship between the copper busbar and the insulating sleeve 12 is not changed; only the cross-sectional area of ​​the copper busbar is changed to achieve different configurations of copper busbars for different power consumptions, realizing a stepped variation and saving overall costs.

[0048] The present invention also discloses a power distribution system for a power transmission bus, including a power transmission bus and a plug box 3. The plug box 3 and the power transmission bus are detachably connected. The plug box 3 is provided with a number of plugs 31 inside. The conductive end of the plug 31 is snapped into the power take-up channel 14, and the conductive end of the plug 31 abuts against two power transmission parts 13. The output end of the plug 31 is electrically connected to a plug 32.

[0049] In this embodiment, the plug-in box 3 is the power extraction device, a key structure for extracting power from the power transmission bus. In this embodiment, the conductive end of the plug 31 is snapped into the power extraction channel 14, and the conductive end of the plug 31 abuts against the two power transmission sections 13. Since the two power transmission sections 13 within the same conductive cavity 11 have opposite polarities, the plug 31 obtains the power transmitted from the two power transmission sections 13 through its conductive end, and transmits the obtained power out through the plug 32, which is electrically connected to its output end, thus completing the power extraction operation. Furthermore, since the power transmission bus has several independent but electrically conductive power transmission sections 13, the plug-in box 3 can be detachably connected to any position on the bus body 1, enabling power extraction without requiring a rearrangement of the workshop's power distribution system, thus adapting to situations such as the addition, removal, or relocation of workshop equipment.

[0050] In this embodiment, the connector 31 has two independent power transmission structures, which are electrically connected to two power transmission sections 13 within the same busbar body 1. In this embodiment, the connector 31 can transmit power between the connector 31 and the power transmission section 13 via wires, cables, or other structures. In a further optimized design, the connector 31 includes a second insulating partition 311. Two conductive abutment pieces 312 are respectively provided on both sides of the second insulating partition 311 near the power transmission section 13. The two conductive abutment pieces 312 abut against the two power transmission sections 13, and are electrically connected to the plug 32. In this embodiment, the power transmission section 13 is made of copper busbar, which has a plate-like structure. In this embodiment, power transmission is achieved by the conductive abutment pieces 312 abutting against the power transmission section 13, and the second insulating partition 311 insulates the two conductive abutment pieces 312, preventing short circuits caused by contact between the two conductive abutment pieces 312.

[0051] In this embodiment, the contact conductive sheet 312 is made of elastic material and has a continuous wavy structure, which improves the elasticity of the contact conductive sheet 312 and ensures that the contact conductive sheet 312 is in close contact with the power transmission part 13, thus ensuring power supply safety. In this embodiment, the connector 31 also includes a third insulating plate 313. There are two third insulating plates 313 in each set of connectors 31, which are respectively arranged on the side of the contact conductive sheet 312 away from the second insulating partition 311. The second insulating partition 311 and the third insulating plate 313 achieve insulation of the contact conductive sheet 312. A copper plate is provided between the third insulating plate 313 and the contact conductive sheet 312. The copper plate is detachably connected to a wire lug, which transmits the power obtained by the contact conductive sheet 312. In this embodiment, the third insulating plate 313 and the copper plate ensure that one end of the contact conductive sheet 312 is relatively fixed, further ensuring that the shape of the contact conductive sheet 312 does not change. Of course, the plug 32 in this embodiment is an industrial plug. In some embodiments, a switch, electrical components, etc. are also electrically connected between the connector 31 and the plug 32 to further ensure electrical safety.

[0052] In a further optimized design, a connecting plate 16 is fixedly installed on the side of the busbar body 1 facing away from the power extraction channel 14. The connecting plate 16 is detachably connected to the ceiling structure 4. During installation in this embodiment, workers design the route of the transmission busbar and various installation details based on the different workshops or actual installation spaces and the power requirements at different locations. The ceiling structure 4 is then installed on the top of the workshop or actual installation space. The transmission busbar is installed by detachably connecting the connecting plate 16 to the ceiling structure 4. Power can be extracted by detachably connecting the plug-in box 3 to any location on the busbar body 1 without needing to rearrange the workshop's power distribution system, thus adapting to situations such as the addition, removal, or relocation of workshop equipment.

[0053] Preferably, the plug-in box 3 and the busbar body 1 are slidably connected. A guide plate 33 is detachably connected to the side of the plug-in box 3 closest to the busbar body 1. The guide plate 33 is arranged along the extension direction of the busbar body 1, and two sets of guide plates 33 are respectively arranged on both sides of the busbar body 1. In this embodiment, the plug-in box 3 and the busbar body 1 are slidably connected. Since the power supply channel 14 extends in the same direction as the busbar body 1, the position of the plug-in box 3 on the busbar body 1 can be adjusted by sliding, and this process can be completed without power interruption. During installation, the two guide plates 33 are used to align and guide the plug-in box 3 and the busbar body 1, reducing the difficulty of installation. Preferably, the guide plate 33 is an elastic plate, and the distance between the guide plate 33 and the busbar body 1 gradually decreases from the busbar body 1 to the plug-in box 3, that is, the distance between the two guide plates 33 is the largest at the installation opening, ensuring the guiding function of the guide plate 33.

[0054] Further optimization of the scheme: the two ends of the plug-in box 3 are detachably connected to locking mechanisms, which include mounting plates 51, clamping members 52, and driving members 53; the mounting plates 51 are detachably connected to the ends of the plug-in box 3; two sets of clamping members 52 are provided, both of which are slidably connected to the mounting plates 51, and the two sets of clamping members 52 are symmetrically arranged about a first axis; the clamping members 52 include a pressing part 521 that abuts against and presses against the busbar body 1; the driving member 53 is slidably connected to the mounting plates 51, and the sliding direction of both is the direction of the first axis; the connection points of the clamping members 52 and the driving member 53 are the first connecting surface 522 and the second connecting surface 531, respectively; along the direction of the first axis toward the pressing part 521, the vertical distance between the first connecting surface 522 and the first axis gradually decreases; based on the sliding of the driving member 53, the second connecting surface 531 applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522, and the sliding trajectory of the clamping member 52 is perpendicular to the first connecting surface 522. In this embodiment, the busbar body 1 includes a protrusion that abuts and presses against the pressing part 521.

[0055] When the present invention is in operation, the driving member 53 slides along the first axis direction, the second connecting surface 531 applies a force perpendicular to the first connecting surface 522 to the first connecting surface 522, and the clamping member 52 slides along the sliding trajectory direction and is connected to the mounting plate 51. The sliding trajectory of the clamping member 52 is perpendicular to the first connecting surface 522. Therefore, the force applied by the second connecting surface 531 to the first connecting surface 522 drives the clamping member 52 to move along the sliding trajectory direction. Since the two sets of clamping members 52 are symmetrically arranged with respect to the first axis, the distance between the pressing parts 521 increases or decreases under the action of the driving member 53, so that the pressing part 521 of the clamping member 52 abuts against and clamps the busbar body 1 or releases the busbar body 1, thereby quickly realizing the disassembly and assembly work between the mounting plate 51 and the busbar body 1.

[0056] In a further optimized design, the clamping member 52 is provided with a first slide rail 523 along the extension direction of the first connecting surface 522. The first slide rail 523 and the driving member 53 are slidably connected. The first connecting surface 522 and the second connecting surface 531 are respectively the contact surfaces of the first slide rail 523 and the driving member 53 and the contact surfaces of the driving member 53 and the first slide rail 523. The clamping member 52 is provided with a first sliding groove 524 along its sliding trajectory direction. A first sliding rod 525 is slidably arranged in the first sliding groove 524. The first sliding rod 525 and the mounting plate 51 are detachably connected. In this embodiment, since the first slide rail 523 and the driving member 53 are slidably connected, the position of the driving member 53 relative to the first slide rail 523 will change when the driving member 53 slides along the first axis. That is, the contact area between the first connecting surface 522 and the second connecting surface 531 changes. However, under the constraint of the sliding connection, the second connecting surface 531 continuously applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522. Moreover, the clamping member 52 is constrained by the driving member 53, so the clamping member 52 cannot exert force. The clamping member 52 rotates, and the first sliding groove 524 and the first sliding rod 525 provide the clamping member 52 with a degree of freedom along the sliding trajectory. Therefore, under the force applied by the second connecting surface 531 to the first connecting surface 522, the clamping member 52 moves along the sliding trajectory. Since the two sets of clamping members 52 are symmetrically arranged about the first axis, the distance between the pressing parts 521 increases or decreases under the action of the driving member 53, so that the pressing part 521 of the clamping member 52 abuts against or releases the busbar body 1, thereby quickly realizing the disassembly and assembly of the mounting plate 51 and the busbar body 1. Of course, other methods can also be used in this embodiment to drive the clamping member 52 to move along the sliding trajectory, such as electric cylinders, pneumatic cylinders, etc. However, compared with the driving structure used in this application, no electric drive is required, and manual operation is sufficient, which is convenient and easy.

[0057] In this embodiment, the first connecting surface 522 and the second connecting surface 531 can adopt curved surface contact, planar contact, or non-linear surface contact. Preferably, the two ends of the movement trajectory of the driving member 53 are a first end and a second end, respectively: the first end is the end of the movement trajectory of the driving member 53 that is close to the pressing part 521. When the driving member 53 is located at the first end, the distance between the two pressing parts 521 is a first distance; when the driving member 53 is located at the second end, the distance between the two pressing parts 521 is a second distance, and the first distance is greater than the second distance; both the first connecting surface 522 and the second connecting surface 531 are planar, and the distance from the first connecting surface 522 to the first axis gradually increases from the first end to the second end. In this embodiment, by controlling the change in distance between the first connecting surface 522 and the first axis, the first connecting surface 522 and the first axis are at a certain angle, so that the first connecting surface 522 is arranged at an angle, ensuring that the first connecting surface 522 and the second connecting surface 531 are in inclined contact. When the driving member 53 slides along the direction of the first axis, the second connecting surface 531 applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522.

[0058] In this embodiment, when the driving member 53 is located at the first end, the distance between the two pressing parts 521 is a first distance; when the driving member 53 is located at the second end, the distance between the two pressing parts 521 is a second distance, and the first distance is greater than the second distance. Therefore, when the driving member 53 moves between the first end and the second end of the motion trajectory, the distance between the two pressing parts 521 also increases or decreases. The present invention can determine the position of the pressing part 521 according to the structure of the busbar body 1. In this embodiment, the pressing position of the busbar body 1 and the pressing member 52 is located between the two pressing members 52. Therefore, the pressing part 521 is arranged on the side of the pressing member 52 close to the first axis. When the driving member 53 is located at the first end, the busbar body 1 and the pressing member 52 are arranged at intervals; when the driving member 53 is located at the second end, the busbar body 1 and the pressing member 52 are in a pressing state.

[0059] Preferably, the clamping member 52 has a pressure head 526 on the side near the busbar body 1, and an elastic sleeve 527 is sleeved on the outside of the pressure head 526. In this embodiment, when the busbar body 1 and the clamping member 52 are in contact and pressed together, the pressure head 526 is in contact and pressed together with the busbar body 1, and the pressure head 526 is the part of the clamping member 52 that applies pressure to the busbar body 1. The elastic sleeve 527 is made of elastic material, and the side of the elastic sleeve 527 near the busbar body 1 is serrated, so as to protect the busbar body 1.

[0060] In this embodiment, the friction between the mounting plate 51 and the driving member 53 can cause the driving member 53 to remain at any position on its movement trajectory. Preferably, in this embodiment, the locking mechanism further includes a self-locking assembly detachably connected to the mounting plate 51. The self-locking assembly includes a self-locking element detachably connected to the driving member 53. The self-locking element has a first state and a second state: when the self-locking element is in the first state, the pressing part 521 and the busbar body 1 abut and press against each other, and the position of the driving member 53 relative to the mounting plate 51 is fixed; when the self-locking element is in the second state, the pressing part 521 and the busbar body 1 are spaced apart, and the driving member 53 can slide relative to the mounting plate 51. In this embodiment, the self-locking element is detachably connected to the mounting plate 51 and the driving element 53. The self-locking element switches between the first state and the second state to control the position of the driving element 53 relative to the mounting plate 51, thereby controlling the positional change between the pressing part 521 and the bus body 1. The self-locking element locks the position of the driving element 53, further realizing the self-locking function of pressing the pressing part 521 and the bus body 1 together.

[0061] In this solution, the self-locking element can be a linkage component or a separate component. When the self-locking element is a separate component, it can be a limiting rod. The mounting plate 51 has a first limiting hole at the corresponding position of the first and second ends of the driving component 53, and the driving component 53 also has a second limiting hole. When the driving component moves to the first or second end, the first and second limiting holes are aligned, and the limiting rod is inserted into the first and second limiting holes to lock the driving component 53. However, the drawback of this technical solution is that it requires manual judgment to determine whether the first and second limiting holes correspond.

[0062] The design is further optimized so that the self-locking component includes a first protrusion 54 and a second protrusion 55. The first protrusion 54 is detachably connected to the side of the driving member 53 near the clamping member 52. The first protrusion 54 includes a first abutting surface 541 and a first sliding surface 542 arranged sequentially from a first end to a second end. The distance between the first sliding surface 542 and the driving member 53 gradually decreases from the first end to the second end. The second protrusion 55 is slidably connected to the mounting plate 51, and the sliding direction of the second protrusion 55 and the mounting plate 51 is parallel to the rotation axis of the clamping member 52. The second protrusion 55 is correspondingly arranged to the driving member 53. The second protrusion 55 includes a second sliding surface 551 and a second abutting surface 552 arranged sequentially from a first end to a second end. The distance between the second sliding surface 551 and the driving member 53 gradually decreases from the first end to the second end.

[0063] The self-locking assembly also includes a control component slidably connected to the drive member 53. Based on the control component abutting against the second protrusion 55, the position of the second protrusion 55 relative to the mounting plate 51 is controlled. When the self-locking element is in the first state, the first contact surface 541 and the second contact surface 552 are in contact connection. When the self-locking element is in the second state, the first contact surface 541 and the second contact surface 552 are arranged at intervals, and the first sliding surface 542 and the second sliding surface 551 are spaced apart or in sliding contact. The first state and the second state of the self-locking element are switched by the control component.

[0064] When the self-locking element switches from the first state to the second state, the control member abuts against the second protrusion 55, controlling the position of the second protrusion 55 relative to the mounting plate 51. This causes the second sliding surface 551 and the second contact surface 552 of the second protrusion 55 to move to the side of the mounting plate 51 away from the drive member 53. Without the restriction of the second protrusion 55, the drive member 53 moves along the motion trajectory. The first contact surface 541 and the second contact surface 552 are arranged at intervals, and the first sliding surface 542 and the second sliding surface 551 are spaced apart or slide against each other, ensuring that the drive member 53 can move along the motion trajectory. When the self-locking element switches from the second state to the first state, in the initial state, the first sliding surface 542 and the second sliding surface 551 are arranged opposite each other, that is, they are close to each other. The driving member 53 moves along the motion trajectory, and the first sliding surface 542 and the second sliding surface 551 begin to contact each other. The first sliding surface 542 applies a force perpendicular to the second sliding surface 551 to the second sliding surface 551. Since the second protrusion 55 is slidably connected to the mounting plate 51, and the sliding direction of the second protrusion 55 and the mounting plate 51 is parallel to the rotation axis of the pressing member 52, under this force, the second protrusion 55 begins to move away from the driving member 53 until the self-locking element switches to the first state, that is, the first contact surface 541 and the second contact surface 552 are in contact and connected. The driving member 53 cannot move along the motion trajectory, thus realizing the locking function of the driving member 53, and further realizing the self-locking function of the pressing part 521 and the bus body 1 abutting and pressing.

[0065] In a further optimized design, the control component includes a second sliding rod 561. The driving component 53 has a third through hole for the movement of the second sliding rod 561, and the third through hole is arranged corresponding to the second protrusion. The second protrusion 55 is detachably connected to the third sliding rod 553 on the side opposite to the driving component 53. The mounting plate 51 is detachably connected to the second housing 554 on the side opposite to the driving component 53. The second housing 554 has a third through hole for the sliding of the third sliding rod 553. A second spring 555 is sleeved on the outside of the second sliding rod 561, and the two ends of the second spring 555 are detachably connected to the second housing 554 and the second protrusion 55, respectively.

[0066] The second protrusion 55, under the action of the third sliding rod 553 and the fourth through hole, can only slide along a preset path, and the direction of the preset path is parallel to the rotation axis of the clamping member 52. Under the elastic action of the second spring 555, the second protrusion 55 extends out of its opening to the space between the mounting plate 51 and the driving member 53. When the self-locking element switches from the first state to the second state, the second sliding rod 561 is controlled to pass through the third through hole and abut against the second protrusion 55, controlling the position of the second protrusion 55 relative to the mounting plate 51, so that the second sliding surface 551 and the second abutting surface 552 of the second protrusion 55 move to the side of the mounting plate 51 away from the driving member 53. Without the restriction of the second protrusion 55, the driving member 53 moves along the motion trajectory.

[0067] In a further optimized design, the mounting plate 51 is detachably connected to a fixing plate 57, which is slidably connected to the driving component 53. In this embodiment, the fixing plate 57 is slidably connected to the driving component 53, but the driving component 53 still moves along the first axis direction. The fixing plate 57 and the mounting plate 51 enclose the driving component 53 and the clamping component 52, thus protecting the internal components.

[0068] Preferably, the fixing plate 57 has a first sliding hole along the first axis direction, and the driving member 53 includes a sliding part 532 that is slidably connected to the first sliding hole. In this embodiment, the sliding connection between the first sliding hole and the sliding part 532 is achieved, and during operation, the driving member 53 moves along the first axis direction through the sliding part 532 relative to the first sliding hole.

[0069] Preferably, the first sliding hole is a through hole structure. The sliding part 532 passes through the first sliding hole and is detachably connected to the drive plate 533. In this embodiment, the drive plate 533 drives the sliding part 532 relative to the first sliding hole, thereby realizing the movement of the drive member 53 along the first axis direction. In some embodiments, the drive plate 533 has a mounting hole, which is correspondingly set with the third through hole. A pressing plate 563 is slidably set in the mounting hole. The pressing plate 563 is fixedly connected to the second sliding rod 561. A first spring 562 is sleeved on the outside of the second sliding rod 561. The two ends of the first spring 562 are detachably connected to the pressing plate 563 and the drive member 53, respectively. When the self-locking element switches from the first state to the second state, pressing the pressing plate 563 controls the second sliding rod 561 to pass through the third through hole and abut against the second protrusion 55. After the state switch is completed, under the action of the first spring 562, the second sliding rod 561 moves between the pressing plate 563 and the drive member 53 to prevent the second sliding rod 561 from obstructing the movement of the second protrusion 55.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
