The connection methods between the busway and the plug-in box include welding, bolt connection, etc. Welding, bolt connection, etc. ensure the connection strength between the busway and the plug-in box, but the installation process is complicated, the disassembly is difficult, which is not convenient for the installation of the plug-in box and the subsequent maintenance and repair. Therefore, there is an urgent need to provide a locking mechanism for the busway and the plug-in box that can be quickly disassembled and assembled. Summary of the Invention

[0003] The purpose of the present invention is to provide a locking mechanism for a busway and a plug-in box to solve the problems existing in the above-mentioned prior art.

[0004] To achieve the above purpose, the present invention provides a locking mechanism for a busway and a plug-in box, which includes a mounting plate, a pressing member, a driving member, and a self-locking assembly. The mounting plate is detachably connected to the plug-in box; there are two groups of pressing members, and both are slidably connected to the mounting plate. The two groups of pressing members are symmetrically arranged with respect to a first axis; the pressing member includes a pressing portion that abuts against and presses the busway; the driving member is slidably connected to the mounting plate, and the sliding direction of the two is the first axis direction. The connection parts of the pressing member and the driving member are a first connection surface and a second connection surface respectively.

[0008] Optionally, the self-locking element includes a first protrusion portion and a second protrusion portion. The first protrusion portion is detachably connected to the side of the driving member close to the pressing member. The first protrusion portion includes a first contact surface and a first sliding surface sequentially arranged from the first end to the second end. The distance between the first sliding surface and the driving member gradually decreases from the first end to the second end.

[0009] The second protrusion portion is slidably connected to the mounting plate, and the sliding direction of the second protrusion portion and the mounting plate is parallel to the rotation axis direction of the pressing member. The second protrusion portion is correspondingly arranged with the driving member. The second protrusion portion includes a second sliding surface and a second contact surface sequentially arranged from the first end to the second end. The distance between the second sliding surface and the driving member gradually decreases from the first end to the second end.

[0010] The self-locking assembly further includes a control member slidably connected to the driving member. Based on the control member abutting against the second protrusion portion, the position of the second protrusion portion relative to the mounting plate is controlled. When the self-locking element is in the first state, the first contact surface and the second contact surface are in abutting connection; when the self-locking element is in the second state, when the self-locking element is in the second state, the first contact surface and the second contact surface are arranged at intervals, and the first sliding surface and the second sliding surface are arranged at intervals or in sliding abutment; the first state and the second state of the self-locking element are switched through the control member.

[0011] Optionally, the control member includes a second sliding rod, the driving member is provided with a third through hole for the second sliding rod to move, and the third through hole is arranged corresponding to the second protrusion; the second protrusion is detachably connected to the third sliding rod on the side facing away from the driving member, the mounting plate is detachably connected to the second shell on the side facing away from the driving member, the second shell is provided with a fourth through hole for the third sliding rod to slide, and a second spring is sleeved on the outer side of the second sliding rod, and the two ends of the second spring are detachably connected to the second shell and the second protrusion respectively.

[0016] Compared with the prior art, the present invention has the following advantages and technical effects:

[0017] When the present invention is working, the driving member slides along the first axis direction, the second connecting surface applies a force perpendicular to the first connecting surface to the first connecting surface, and the pressing member slides along the sliding track direction and is connected to the mounting plate, and the sliding track of the pressing member is perpendicular to the first connecting surface, so the force applied by the second connecting surface to the first connecting surface drives the pressing member to move along the sliding track direction, and because the two groups of pressing members are symmetrically arranged about the first axis, under the action of the driving member, the distance between the pressing parts increases or decreases, so that the pressing parts of the pressing members abut against and press the bus duct or release the bus duct, thereby quickly realizing the disassembly and assembly work between the mounting plate and the bus duct. The self-locking element is detachably connected to the mounting plate and the driving member, and the self-locking element switches between the first state and the second state to control the position of the driving member relative to the mounting plate, thereby controlling the position change between the pressing part and the bus duct, and the position locking of the driving member is realized by the self-locking element, and the self-locking function of the pressing part and the bus duct abutting and pressing is further realized.

Detailed implementation manners

[0029] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] As Figures 1-9 , the present invention provides a busbar trunking and plug-in box locking mechanism, which includes a mounting plate 51, a pressing member 52, a driving member 53 and a self-locking assembly; the mounting plate 51 is detachably connected to the plug-in box 3, there are two groups of pressing members 52 and both are slidably connected to the mounting plate 51, and the two groups of pressing members 52 are symmetrically arranged with respect to the first axis; the pressing member 52 includes a pressing portion 521 that abuts against and presses the busbar trunking 1; the driving member 53 is slidably connected to the mounting plate 51 and the sliding direction of the two is the first axis direction, the connection parts of the pressing member 52 and the driving member 53 are the first connection surface 522 and the second connection surface 531 respectively, along the direction of the first axis towards the pressing portion 521, the perpendicular distance between the first connection surface 522 and the first axis gradually decreases; based on the sliding of the driving member 53, the second connection surface 531 applies a force perpendicular to the first connection surface 522 to the first connection surface 522, and the sliding track of the pressing member 52 is perpendicular to the first connection surface 522.

[0031] The self-locking assembly is detachably connected to the mounting plate 51, the self-locking assembly includes a self-locking element detachably connected to the driving member 53, and the self-locking element includes a first state and a second state: when the self-locking element is in the first state, the pressing portion 521 and the busbar trunking 1 abut against and press 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 portion 521 and the busbar trunking 1 are arranged at intervals, and the driving member 53 can slide relative to the mounting plate 51.

[0032] When the present invention works, the driving member 53 slides along the first axis direction, and the second connecting surface 531 applies a force perpendicular to the first connecting surface 522 to the first connecting surface 522. The pressing member 52 is slidably connected to the mounting plate 51 along the sliding track direction, and the sliding track of the pressing 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 pressing member 52 to move along the sliding track direction. Since the two groups of pressing members 52 are symmetrically arranged with respect to the first axis, under the action of the driving member 53, the distance between the pressing portions 521 increases or decreases, so that the pressing portions 521 of the pressing member 52 abut against and press the busbar trunking 1 or release the busbar trunking 1, thereby quickly realizing the disassembly and assembly work between the mounting plate 51 and the busbar trunking 1. The self-locking element is detachably connected to the mounting plate 51 and detachably connected to the driving member 53. The self-locking element switches between the first state and the second state to control the position of the driving member 53 relative to the mounting plate 51, and further controls the position change between the pressing portion 521 and the busbar trunking 1. The position of the driving member 53 is locked by the self-locking element, and the self-locking function of the pressing portion 521 and the busbar trunking 1 abutting and pressing is further realized.

[0033] For a further optimized solution, a first sliding rail 523 is provided on the pressing member 52 along the extending direction of the first connecting surface 522. The first sliding rail 523 is slidably connected to the driving member 53. The first connecting surface 522 and the second connecting surface 531 are respectively the contact surfaces for the cooperation of the first sliding rail 523 and the driving member 53, and the contact surfaces for the cooperation of the driving member 53 and the first sliding rail 523. A first sliding groove 524 is provided on the pressing member 52 along its sliding track direction. A first sliding rod 525 is slidably arranged in the first sliding groove 524, and the first sliding rod 525 is detachably connected to the mounting plate 51. During the operation of this embodiment, since the first sliding rail 523 is slidably connected to the driving member 53, when the driving member 53 slides along the first axis, the position of the driving member 53 relative to the first sliding rail 523 will change, that is, the contact area between the first connecting surface 522 and the second connecting surface 531 changes. However, under the limiting effect of the sliding connection between the first connecting surface 522 and the second connecting surface 531, the second connecting surface 531 continuously exerts a force perpendicular to the first connecting surface 522 on the first connecting surface 522, and there is a constraint of the driving member 53 on the pressing member 52. Therefore, the pressing member 52 cannot rotate. At the same time, the first sliding groove 524 and the first sliding rod 525 provide the pressing member 52 with freedom in the sliding track direction. Therefore, under the action of the force exerted by the second connecting surface 531 on the first connecting surface 522, the pressing member 52 moves along the sliding track direction. And since the two groups of pressing members 52 are symmetrically arranged with respect to the first axis, under the action of the driving member 53, the distance between the pressing portions 521 increases or decreases, so that the pressing portions 521 of the pressing member 52 abut against and press the busbar chute 1 or loosen the busbar chute 1, thereby quickly realizing the disassembly and assembly work between the mounting plate 51 and the busbar chute 1. Of course, other methods can also be adopted in this embodiment to realize the driving member 53 to drive the pressing member 52 to move along the sliding track direction, such as driving structures such as electric cylinders and air cylinders. However, compared with the driving structure adopted in this application, it does not require electric drive and can be manually operated, which is convenient and fast.

[0034] In this embodiment, the first connection surface 522 and the second connection surface 531 can adopt curved surface contact, plane contact or dissimilar surface contact. Preferably, the two ends of the movement trajectory of the driving member 53 are respectively a first end and a second end: the first end is the end of the movement trajectory of the driving member 53 close to the pressing portion 521. When the driving member 53 is located at the first end, the distance between the two pressing portions 521 is a first distance; when the driving member 53 is located at the second end, the distance between the two pressing portions 521 is a second distance, and the first distance is greater than the second distance; both the first connection surface 522 and the second connection surface 531 are planes, and the distance from the first connection surface 522 to the first axis gradually increases from the first end to the second end. In this embodiment, by controlling the change in the distance from the first connection surface 522 to the first axis, an angle is formed between the first connection surface 522 and the first axis, so that the first connection surface 522 is arranged obliquely, ensuring that the first connection surface 522 and the second connection surface 531 are in oblique contact. When the driving member 53 slides along the first axis direction, the second connection surface 531 exerts a force perpendicular to the first connection surface 522 on the first connection surface 522.

[0035] In this embodiment, since the distance between the two pressing portions 521 is a first distance when the driving member 53 is located at the first end; the distance between the two pressing portions 521 is a second distance when the driving member 53 is located at the second end, 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 movement trajectory, the distance between the two pressing portions 521 also increases or decreases. The present invention can determine the position of the pressing portion 521 according to the structure of the busbar groove 1. In this embodiment, the abutting and pressing position of the busbar groove 1 and the pressing member 52 is between the two pressing members 52. Therefore, the pressing portion 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 groove 1 and the pressing member 52 are arranged at intervals; when the driving member 53 is located at the second end, the busbar groove 1 and the pressing member 52 are in an abutting and pressing state.

[0036] Preferably, a pressing head 526 is arranged on the side of the pressing member 52 close to the busbar groove 1, and an elastic sleeve 527 is sleeved outside the pressing head 526. When the busbar groove 1 and the pressing member 52 are in abutting and pressing in this embodiment, the pressing head 526 abuts and presses against the busbar groove 1, and the pressing head 526 is the pressing portion of the pressing member 52 against the busbar groove 1. The elastic sleeve 527 is made of an elastic material, and the side of the elastic sleeve 527 close to the busbar groove 1 is serrated to protect the busbar groove 1 through the elastic sleeve 527.

[0037] It further includes a self-locking component detachably connected to the mounting plate 51. The self-locking component 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 portion 521 abuts and presses against the busbar groove 1, 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 portion 521 and the busbar groove 1 are arranged at intervals, 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 member 53. The self-locking element switches between the first state and the second state to control the position of the driving member 53 relative to the mounting plate 51, and further control the position change between the pressing portion 521 and the busbar groove 1. The position of the driving member 53 is locked by the self-locking element, and the self-locking function of the pressing portion 521 abutting and pressing against the busbar groove 1 is further realized.

[0038] In this solution, the self-locking element can be a linkage member or a separate component; when the self-locking element is a separate component, the self-locking element can be a limiting rod. The mounting plate 51 is provided with a first limiting hole at the positions corresponding to the first end and the second end of the driving member 53, and the driving member 53 is also provided with a second limiting hole. When the driving member moves to the first end or the second end, the first limiting hole and the second limiting hole are correspondingly arranged, and the limiting rod is inserted into the first limiting hole and the second limiting hole to lock the position of the driving member 53. However, the disadvantage of this technical solution is that it is necessary to manually judge whether the pair of the first limiting hole and the second limiting hole corresponds.

[0039] In a further optimized solution, the self-locking element includes a first convex portion 54 and a second convex portion 55. The first convex portion 54 is detachably connected to the side of the driving member 53 close to the pressing member 52. The first convex portion 54 includes a first abutting surface 541 and a first sliding surface 542 arranged in sequence from the first end to the 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 convex portion 55 is slidably connected to the mounting plate 51, and the sliding direction of the second convex portion 55 and the mounting plate 51 is parallel to the rotation axis direction of the pressing member 52. The second convex portion 55 is correspondingly arranged with the driving member 53. The second convex portion 55 includes a second sliding surface 551 and a second abutting surface 552 arranged in sequence from the first end to the 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.

[0040] The self-locking component further includes a control member slidably connected to the driving member 53. Based on the contact between the control member and 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 member.

[0041] When the self-locking element switches from the first state to the second state, by contacting the second protrusion 55 through the control member, the position of the second protrusion 55 relative to the mounting plate 51 is controlled, so that the second sliding surface 551 and the second contact surface 552 of the second protrusion 55 all 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 movement track, so that 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, ensuring that the driving member 53 can move along the movement track. When the self-locking element switches from the second state to the first state, at the starting state, the first sliding surface 542 and the second sliding surface 551 are arranged opposite to each other, that is, they are close to each other. The driving member 53 moves along the movement track, and the first sliding surface 542 and the second sliding surface 551 start to contact each other. The first sliding surface 542 exerts a force perpendicular to the second sliding surface 551 on 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 direction of the pressing member 52, under this force, the second protrusion 55 starts to move to the side 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 connection, and the driving member 53 cannot move along the movement track, realizing the locking function of the driving member 53 and further realizing the self-locking function of the pressing portion 521 and the busbar groove 1 being in contact and pressed.

[0042] In a further optimized solution, the control member includes a second sliding rod 561. A third through hole for the movement of the second sliding rod 561 is provided on the driving member 53, and the third through hole is arranged corresponding to the second protrusion. A third sliding rod 553 is detachably connected to the side of the second protrusion 55 away from the driving member 53. A second housing 554 is detachably connected to the side of the mounting plate 51 away from the driving member 53. A third through hole for the sliding of the third sliding rod 553 is provided on the second housing 554. A second spring 555 is sleeved on the outer side of the third sliding rod 553, and both ends of the second spring 555 are detachably connected to the second housing 554 and the second protrusion 55 respectively.

[0043] The second protrusion 55 can only slide along a preset path under the action of the third sliding rod 553 and the fourth through hole, and the direction of the preset path is parallel to the rotation axis direction of the pressing member 52. Under the elastic action of the second spring 555, the second protrusion 55 extends out of the opening where it is located to between the mounting plate 51 and the driving member 53. When the self-locking element switches from the first state to the second state, control the second sliding rod 561 to penetrate through the third through hole and abut against the second protrusion 55, and control 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 all 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 movement track.

[0044] In a further optimized solution, the mounting plate 51 is detachably connected with a fixing plate 57, and the fixing plate 57 is slidably connected with the driving member 53. In this embodiment, the fixing plate 57 is slidably connected with the driving member 53, but the driving member 53 still moves along the first axis direction, and the driving member 53 and the pressing member 52 are wrapped by the fixing plate 57 and the mounting plate 51 to protect the internal components.

[0045] Preferably, the fixing plate 57 is provided with a first sliding hole 571 along the first axis direction, and the driving member 53 includes a sliding portion 532 slidably connected with the first sliding hole 571; in this embodiment, it is realized by the sliding connection between the first sliding hole 571 and the sliding portion 532, and during operation, the driving member 53 moves along the first axis direction through the sliding portion 532 relative to the first sliding hole 571.

[0046] Preferably, the first sliding hole 571 is a through hole structure, and after the sliding portion 532 penetrates through the first sliding hole 571, it is detachably connected with a driving plate 533. In this embodiment, the driving plate 533 drives the sliding portion 532 relative to the first sliding hole 571, thereby realizing the movement of the driving member 53 along the first axis direction. In some embodiments, the driving plate 533 is provided with a mounting hole, the mounting hole and the third through hole are correspondingly arranged, a pressing plate 563 is slidably arranged in the mounting hole, the pressing plate 563 is fixedly connected with the second sliding rod 561, and a first spring 562 is sleeved outside the second sliding rod 561. The two ends of the first spring 562 are respectively detachably connected with the pressing plate 563 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 penetrate through the third through hole and abut against the second protrusion 55 by pressing the pressing plate 563. After the state switching is completed, under the action of the first spring 562, the second sliding rod 561 moves between the pressing plate 563 and the driving member 53 to prevent the second sliding rod 561 from interfering with the movement of the second protrusion 55.
