Description

Technical Field

[0001] This application relates to the field of installation equipment technology, and in particular to a limiting installation structure and equipment box. Background Technology

[0002] As rail transit vehicles become more functional, the amount of electrical equipment requiring installation in cabinets is increasing. To fully utilize the space within the cabinets, some electrical equipment is mounted on hinged mounting plates, similar to cabinet doors, allowing for multi-layered equipment arrangement. These mounting plates can also be easily opened for maintenance of other electrical equipment within the cabinet. Because these mounting plates house considerable weight and some electrical equipment, they need to be locked to ensure absolute stability during vehicle operation.

[0003] Currently, some similar cabinet structures use a fixing method where a positioning plate is welded to the cabinet's uprights, and a rectangular through-hole is drilled in the hinge-type equipment mounting plate. When the mounting plate is closed, the positioning plate inserts into the rectangular through-hole to achieve positioning. However, to ensure the positioning plate can smoothly insert into the rectangular through-hole even with manufacturing errors, the size of the rectangular through-hole is larger than the positioning plate. This allows the hinge-type equipment mounting plate to still move relative to the positioning plate, thus not providing a complete lock. When the vehicle is running, the hinge-type equipment mounting plate is not fully secured, causing some deformation and affecting the electrical components and wiring mounted on it.

[0004] Therefore, it is crucial to completely lock the hinged equipment mounting plate in order to ensure the stability of electrical components and the safety of vehicle operation. Summary of the Invention

[0005] Therefore, it is necessary to provide a limiting installation structure to address the above-mentioned problems.

[0006] The first aspect of this application provides a limiting installation structure, including:

[0007] First column and second column;

[0008] A first locking member is provided on one of the first column and the second column;

[0009] Mounting body, the mounting body being used to mount a device, the first side of the mounting body being movably connected to the other of the first column and the second column;

[0010] A second locking member is disposed on the second side of the mounting body. The second locking member can dock with the first locking member to limit the rotational stroke of the mounting body and limit the movement of the mounting body along the first direction.

[0011] In the aforementioned limiting installation structure, by placing the first locking member on either the first or second column, the mounting body is movably connected to the other of the first or second column. The second locking member is mounted on the mounting body and can rotate with it until the first locking member aligns with the second locking member mounted on the second column. The second locking member then restricts further rotation of the mounting body, thus achieving rotational limiting of the mounting body. Furthermore, when the first and second locking members align, the second locking member restricts movement of the mounting body along the first direction, further securing the mounting body. Throughout this process, the second locking member, through its cooperation with the first locking member, achieves rotational limiting and directional limiting of the mounting body. Additionally, the second locking member provides a locking surface for the installable door lock, forming a triple limiting mechanism.

[0012] In one embodiment, the limiting installation structure further includes a first door lock, which is disposed on the second locking member. The first door lock has a locked state connected to the first locking member and an unlocked state separated from the first locking member.

[0013] In the locked state, the bolt of the first door lock is locked with the first locking member;

[0014] In the unlocked state, the bolt of the first door lock is separated from the first locking member.

[0015] Thus, by setting a first lock on the second locking member, the bolt of the first lock can abut against the first locking member, thereby achieving the abutment between the first lock and the first locking member, which can lock the installation body. When it is necessary to separate the bolt of the first lock from the first locking member, the installation body can be unlocked.

[0016] In one embodiment, the second locking member includes a first stop portion and two second stop portions, the two second stop portions being spaced apart at opposite ends of the first stop portion along the first direction.

[0017] Thus, the second locking member cooperates with the first locking member to limit the movement through the first stop and the second stop. The second stop is inclined relative to the first stop. Therefore, when the second locking member cooperates with the first locking member, the first locking member can limit the second locking member in a first direction, thereby further restricting the movement of the second locking member and the mounting body connected to the second locking member.

[0018] In one embodiment, the first locking member includes a locking body, the locking body including a first limiting surface, a second limiting surface and a third limiting surface, the first limiting surface and the third limiting surface being disposed opposite to each other, and the second limiting surface being provided in two corresponding to the second stop portion;

[0019] In the locked state, the first limiting surface abuts against the first stop portion, each of the second limiting surfaces abuts against the corresponding second stop portion, and the third limiting surface abuts against the bolt of the first door lock.

[0020] In the unlocked state, the first limiting surface is separated from the first stop, each of the second limiting surfaces is separated from the corresponding second stop, and the third limiting surface is separated from the bolt of the first door lock.

[0021] Thus, the locking and unlocking operations of the installation body are achieved through the mutual cooperation between the first limiting surface and the first stop, the second limiting surface and the second limiting surface, and the third limiting surface and the first door lock.

[0022] In one embodiment, the two second stops are respectively inclined toward the same side away from the first stop, so that the two second stops form an angle with the first stop, and each second limiting surface can be adapted to the inclination angle between the second stop and the first stop, so that the second limiting surface can fit with the second stop.

[0023] Thus, by setting the inclination angles of the second limiting surface and the second stop to be consistent, it is ensured that the second limiting surface can fully fit with the second stop, thereby ensuring the stability of the limiting effect between the second limiting surface and the second stop.

[0024] In one embodiment, at least two first locking members are provided, and the at least two first locking members are spaced apart along the length direction of the second column;

[0025] The second locking member is provided in at least two, and the at least two second locking members are all provided on the second side of the mounting body. The at least two first locking members can be connected to the at least two second locking members one by one.

[0026] Thus, at least two first locking members are provided at intervals along the length of the second column, and the second locking members are adapted to the first locking members to ensure that the first locking members can be adapted to the second locking members provided on each part of the second side of the mounting body, so as to avoid insufficient locking effect that may be formed by partial locking.

[0027] In one embodiment, the limiting installation structure further includes a door panel, which is movably connected to the first column and can cover the installation body.

[0028] In this way, the door panel covering the mounting body can effectively protect the safety of the devices installed on the mounting body.

[0029] In one embodiment, the limiting installation structure further includes a second door lock, which is disposed on the door panel;

[0030] The second side of the mounting body is also provided with a locking part, and the locking part is provided with a lock hole. The bolt of the second door lock can be inserted into the corresponding lock hole to lock the mounting body and the door panel.

[0031] Thus, the locking part is located at the interval between adjacent first locking members to avoid interference between the locking of the locking part and the locking of the first locking member. The locking part can also cooperate with the second door lock to ensure that the door panel and the mounting body can be locked together, preventing the door panel from opening during movement and thus exposing the components installed on the mounting body.

[0032] In one embodiment, the door panel is provided with an observation hole, which is used to correspond to the device.

[0033] Thus, the status of the devices installed on the mounting body can be observed through the observation hole set in the door panel without opening the door panel.

[0034] The second aspect of this application provides a device enclosure that employs a limiting installation structure described in the first aspect of this application.

[0035] Thus, the equipment box adopts the aforementioned limiting installation structure, and therefore also has the aforementioned advantages. Attached Figure Description

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] like Figure 1 As shown, an embodiment of this application provides a limiting installation structure, including a first column 10, a second column 20, a first locking member 40, a second locking member 50, and a mounting body 30. The first locking member 40 is disposed on one of the first column 10 and the second column 20; specifically, in this embodiment, the first locking member 40 is disposed on the second column 20. The mounting body 30 is used to install a device 90. Optionally, the mounting body 30 can be used to install electrical equipment, and a first side of the mounting body 30 is movably connected to the other of the first column 10 and the second column 20. Here, the first side of the mounting body 30 is hinged to the first column 10. The second locking member 50 is disposed on the second side of the mounting body 30. The second locking member 50 can rotate with the mounting body 30 around the first column 10 until the second locking member 50 mates with the first locking member 40. After the first locking member 40 and the second locking member 50 are mated, the first locking member 40 can restrict the rotational stroke of the mounting body 30. At the same time, the first locking member 40 can also restrict the movement of the second locking member 50 along the first direction. In this embodiment, the first direction is the length direction of the first column 10 and the second column 20.

[0050] like Figure 1 As shown, in one embodiment, the limiting installation structure includes a first door lock 53, which is disposed within the second locking member 50, specifically within a mounting hole 54 formed in the first stop portion 51. The first door lock 53 has a locked state connected to the first locking member 40 and an unlocked state separated from the first locking member 40. When in the locked state, the bolt of the first door lock 53 is locked to the first locking member 40; when in the unlocked state, the bolt of the first door lock 53 is separated from the first locking member 40. In this embodiment, the first door lock 53 is a compression door lock.

[0051] like Figure 2 and Figure 4As shown, in one embodiment, the second locking member 50 includes a first stop portion 51 and two second stop portions 52. The two first stop portions 51 are connected to the second stop portions 52, and the two second stop portions 52 are respectively disposed on opposite sides of the first stop portion 51 along a first direction. The second stop portions 52 are disposed facing the same side relative to the first stop portion 51, and the two second stop portions 52 face opposite directions, both facing away from the first stop portion 51. Thus, the two second stop portions 52 and the first stop portion 51 form an angle, so that the cross-section of the first stop portion 51 and the two second stop portions 52 are wedge-shaped.

[0052] Specifically, both the first stop portion 51 and the second stop portion 52 are plate-shaped structures, and the surfaces of the first stop portion 51 and the second stop portion 52 are set as planes.

[0053] like Figure 6 As shown, in one embodiment, the first locking member 40 includes a locking body 41, which is disposed on the second column 20. The locking body 41 has a countersunk hole 414, and the second column 20 has a fixing hole 21. When connecting the locking body 41 to the second column 20, the countersunk hole 414 is aligned with the fixing hole 21 and then the fixing member 42 is inserted to achieve a fixed connection between the locking body 41 and the second column 20. Thus, the countersunk hole 414 ensures that the fixing member 42 can be completely recessed into the first locking member 40, so as to ensure that the fixing member 42 does not occupy space, and at the same time avoids mutual interference between the fixing member 42 and the first door lock 53 on the first locking member 40.

[0054] Specifically, the locking body 41 includes a first limiting surface 411, a second limiting surface 412, and a third limiting surface 413. When in the locked state, the first limiting surface 411 abuts against the first stop 51, the second limiting surface 412 abuts against the second stop 52, and the third limiting surface 413 abuts against the bolt of the first door lock 53. When the mounting body 30 rotates around the first column 10 and mates with the first locking member 40 on it and the second locking member 50 on the second column 20, the first limiting surface 411 of the locking body 41 is flat and can completely fit with the contact surface of the first stop 51. Similarly, the second limiting surface 412 is also set as a plane so that the second limiting surface 412 can be completely fitted with the contact surface of the second stop portion 52. Since the second stop portion 52 is arranged on opposite sides of the first stop portion 51 along the first direction, the second limiting surface 412 corresponds to the second stop portion 52 so that the second limiting surface 412 is also arranged on opposite sides of the locking body 41 along the first direction, thereby realizing the limiting cooperation between the first limiting surface 411, the second limiting surface 412 and the first stop portion 51, the second stop portion 52.

[0055] More specifically, the second limiting surfaces 412 on both sides of the locking body 41 along the first direction are wedge-shaped slopes, and the contact surfaces of the second stop portions 52 on both sides of the second locking member 50 along the first direction are also wedge-shaped slopes. Therefore, when the mounting body 30 rotates in the forward direction (locking direction), that is, when the second locking member 50 and the first locking member 40 may have some error in the vertical direction, the wedge-shaped slopes allow the first locking member 40 and the second locking member 50 to move under the guidance of the wedge-shaped slopes until they are fully engaged to form a limit. Furthermore, even during vehicle operation, the mounting body 30 will not move relative to the first locking member 40 along the first direction, thereby achieving the limit between the first locking member 40 and the mounting body 30.

[0056] Furthermore, once the mounting body 30 is in full contact with the first locking member 40, it is necessary to restrict the rotation of the mounting body 30. Therefore, the first door lock 53 (compression lock) mounted on the mounting body 30 is rotated 90°. At this time, if the mounting body 30 rotates in the opposite direction (unlocking direction), the bolt of the compression lock will press against the third limiting surface 413 of the first locking member 40, thereby restricting the mounting body 30 from further rotating in the opposite direction. This achieves the limiting of the mounting body 30 and the first locking member 40 in the unlocking direction.

[0057] More specifically, when the third limiting surface 413 is locked to the bolt of the first door lock 53, the mounting body 30 is first rotated in the positive direction (locking direction) around the first column 10 so that the first limiting surface 411 and the first stop 51, and the second limiting surface 412 and the second stop 52 are fully engaged. Then, the outlet of the bolt of the first door lock 53 is located in the area behind the third limiting surface 413, and the area behind the third limiting surface 413 does not restrict the bolt of the first door lock 53 from extending. Therefore, when the first limiting surface 411 and the first stop 51, and the second limiting surface 412 and the second stop 52 are fully engaged, it can be ensured that the bolt of the first door lock 53 can extend smoothly, and the extended bolt can abut against the third limiting surface 413. Thus, the bolt can restrict the reverse rotation (unlocking direction) of the mounting body 30, and the first limiting surface 411 of the locking body 41 can restrict the continuous forward rotation of the mounting body 30. In turn, through the cooperation of the locking body 41 and the bolt, the rotation stroke of the mounting body 30 can be limited, thereby ensuring the stability of the position of the mounting body 30 after locking.

[0058] like Figure 1 and Figure 8 As shown, when the mounting body 30 is installed according to... Figure 1When the closing direction (locking direction) is shown, the second locking member 50 will come into contact with the corresponding first locking member 40. At this time, after the first limiting surface 411 of the locking body 41 of the first locking member 40 abuts against the first stop part 51, the mounting body 30 can be restricted from continuing to rotate in the direction shown in the figure, thereby achieving the purpose of restricting the mounting body 30 from rotating further.

[0059] Simultaneously, the second limiting surfaces 412 provided on opposite sides of the locking body 41 along the first direction can abut against the second stop portion 52 of the second locking member 50. Furthermore, to ensure that the second limiting surface 412 of the locking body 41 can fully abut against the second stop portion 52, the second limiting surface 412 of the locking body 41 can be adapted to the tilt angle of the first stop portion 51 and the second stop portion 52. This ensures that when the locking body 41 contacts the second stop portion 52, the second stop portion 52 can fully fit against the second limiting surface 412. At this time, the first locking member 40 can limit the second stop portion 52, thereby achieving the limitation of the mounting body 30 in the first direction.

[0060] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting body 30 and the first locking member 40 can be welded together to form a whole. Three notches can be provided on the second side of the mounting body 30, the size of which is adapted to the shape of the second locking member 50, so as to facilitate welding the second locking member 50 to the mounting body 30. After the mounting body 30 and the second locking member 50 are welded together to form a whole, the first stop portion 51 and the second stop portion 52 of the second locking member 50 can form a groove. When the first locking member 40 and the second locking member 50 are mated, the first locking member 40 can be embedded into the groove formed by the second locking member 50, so that the first locking member 40 and the second locking member 50 can cooperate and be hidden in the groove. Therefore, the cooperation of the first locking member 40 and the second locking member 50 will not affect the device 90 installed on the mounting body 30 or the internal space.

[0061] like Figure 5 As shown, in one embodiment, at least two first locking members 40 are provided, and the at least two first locking members 40 are spaced apart along the length direction of the second column 20. Second locking members 50 are provided in a one-to-one correspondence with the first locking members 40. In this embodiment, three first locking members 40 are provided, and the three first locking members 40 are spaced apart. Therefore, three second locking members 50 are also provided, and the three second locking members 50 are located on the second side of the mounting body 30 corresponding to the positions of the first locking members 40. Furthermore, the first locking members 40 are mounted on the second column 20, and the mounting positions of the first locking members 40 are laser-marked on the second column 20 to ensure the accuracy of the mounting position of the first locking members 40 on the second column 20.

[0062] like Figure 3 As shown, in one embodiment, the second side of the mounting body 30 is further provided with at least two locking parts 60, each locking part 60 being disposed between two adjacent first locking members 40, and each locking part 60 being provided with a lock hole 61 so that the corresponding lock tongue can be inserted therein to achieve locking.

[0063] Specifically, the locking part 60 is positioned on the second side of the mounting body 30 corresponding to the position of the first locking member 40 on the second post 20. Therefore, the locking part 60 can be spaced apart from the first locking member 40 to avoid interference between the locking part 60 and the first locking member 40 during the docking process of the mounting body 30 and the first locking member 40.

[0064] like Figure 7 As shown, in one embodiment, the limiting mounting structure further includes a door panel 70, which is hinged to one of the first column 10 and the second column 20 via a hinge member 80. The door panel 70 is hinged to the first column 10, and the hinge member 80 can be a hinge. That is, the door panel 70 can rotate around the first column 10 so that the door panel 70 can completely cover the mounting body 30. Optionally, the size of the door panel 70 can be set to be greater than or equal to the size of the mounting body 30 to achieve protection for the equipment installed on the mounting body 30.

[0065] like Figure 3 and Figure 7 As shown, in one embodiment, the door panel 70 is also provided with a second door lock 71. The bolt of the second door lock 71 can be inserted into the lock hole 61 opened on the corresponding locking part 60 to realize the locking operation between the mounting body 30 and the door panel 70.

[0066] like Figure 7 As shown, in one embodiment, the door panel 70 is also provided with an observation hole 72. The position of the observation hole 72 corresponds to the position of the device 90 installed on the mounting body 30, so that the operator can obtain the status of the device 90 through the observation hole 72.

[0067] like Figure 8As shown, after the mounting body 30 is locked, the door panel 70 can rotate around the first column 10 via the hinge 80 to cover the mounting body 30. When the door panel 70 is rotated to the position where it completely covers the mounting body 30, the second door lock 71 on the door panel 70 can be rotated so that the bolt of the second door lock 71 extends and inserts into the lock hole 61 of the locking part 60, thereby locking the door panel 70. This structural design allows operators to inspect and maintain the devices 90 installed on the mounting body 30 by opening only the door panel 70. If inspection and maintenance of the equipment behind the mounting body 30 is required, the mounting body 30 can be opened again to access the equipment behind the mounting body 30. This structural design not only allows for the simultaneous arrangement of multiple layers of equipment and makes full use of space, but also meets the inspection and maintenance needs of each layer of equipment while ensuring the protection and visibility of the outer layer of equipment.
