Description

Technical Field

[0001] This application relates to the field of mechanical connection technology, specifically to a connection module and a non-detachable bolt component. Background Technology

[0002] In related technologies, connecting components such as copper busbars are generally installed and fixed using bolts. When disassembly and maintenance are required, the bolts are prone to falling off the connecting components. In some relatively confined environments, such as inverter cabinets, fallen bolts are often difficult to find. If left unattended, fallen bolts can easily cause abnormal noises inside the cabinet and may also pose safety hazards such as short circuits and damage to the machine.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In a first aspect, this application provides a connection module, including a connection component and a non-detachable bolt component. The connection component is provided with a first through hole. The non-detachable bolt component includes a connection bolt and a limiting member. The connection bolt includes a head and a rod portion. The rod portion is inserted into the first through hole and has a stepped surface facing the head. The limiting member is connected to the connection component and is used to abut against the stepped surface.

[0005] Optionally, the rod includes a thick neck section and a first thin neck section, the thick neck section being farther away from the head relative to the first thin neck section, and the stepped surface being disposed between the thick neck section and the first thin neck section.

[0006] Optionally, the thick neck section is provided with external threads.

[0007] Optionally, the non-detachable bolt component further includes a first washer disposed on the side of the head facing the connecting component.

[0008] Optionally, the limiting member is located on the side of the connecting member facing the head.

[0009] Optionally, the limiting member includes at least two limiting portions, each of which is connected to the connecting component, and the stepped surface of the same connecting bolt abuts against at least two of the limiting portions.

[0010] Optionally, each of the limiting parts is provided with a relief groove, and the projection of the bottom wall of the relief groove along the axial direction of the rod is at least partially located on the step surface.

[0011] Optionally, each of the limiting portions that abuts against the stepped surface of the same connecting bolt abuts against each other sequentially in the direction surrounding the same connecting bolt.

[0012] Optionally, the connecting module further includes a fixing bolt, and the limiting member is connected to the connecting component through the fixing bolt.

[0013] Secondly, this application also provides a non-detachable bolt component, installed on a connecting component, the non-detachable bolt component including a connecting bolt and a limiting member, the connecting bolt including a head and a shank, the shank having a stepped surface facing the head, the shank being configured to be inserted into a first through hole of the connecting component, the limiting member being configured to be connected to the connecting component, the limiting member being used to abut against the stepped surface.

[0014] After reading and understanding the accompanying diagrams and detailed descriptions, the other aspects can be understood.

[0015] In this embodiment, the connecting module includes a non-detachable bolt component, which comprises a connecting bolt and a limiting member. The connecting bolt is used to install and fix the connecting component, and the limiting member is installed on the connecting component and abuts against the stepped surface of the connecting bolt. Thus, when the connecting bolt is in a loose state, i.e., when the installation and fixation of the connecting component is released, the abutment between the limiting member and the stepped surface largely prevents the connecting bolt from detaching from the connecting component. This significantly reduces the likelihood of the connecting bolt falling off and becoming unrecoverable, thereby greatly minimizing the risk of abnormal noises and safety hazards caused by the unrecoverable connecting bolt, and ultimately ensuring the safe operation of the equipment.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0034] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0035] The directional terms mentioned in the embodiments of this application, such as "inner" and "outer", are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0036] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In related technologies, connecting components such as copper busbars are generally installed and fixed using bolts. When disassembly and maintenance are required, the bolts are prone to falling off the connecting components. In some relatively confined environments, such as inverter cabinets, fallen bolts are often difficult to find. If left unattended, during inverter operation, factors such as equipment vibration can cause fallen bolts to generate abnormal noise inside the cabinet. Furthermore, for grid-connected inverters, if fallen bolts come into contact with live parts inside the cabinet while powered on, they can easily cause short circuits and other malfunctions, posing a significant safety hazard.

[0038] To address this, this application provides a connection module comprising a connecting component and a non-detachable bolt component. The non-detachable bolt component includes a connecting bolt used to connect the connecting component to the mounting module, thereby achieving a secure connection between the connecting component and the mounting module. When disassembly and maintenance of the connection module is required, the connection between the connecting component and the mounting module can be released by tightening the connecting bolt, but the connecting bolt will not detach from the connecting component. This largely avoids the situation where the connecting bolt falls off and cannot be found, and consequently, it also largely avoids abnormal noises and safety hazards caused by the connecting bolt falling off and not being found, thus better ensuring the safe operation of the equipment.

[0039] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a connecting component.

[0040] In some implementations, such as Figure 1 As shown, the connecting component 1000 can be a rigid-flexible composite plate, including two rigid connecting parts 1100 and a flexible connecting part 1200. The flexible connecting part 1200 is used to connect the two rigid connecting parts 1100.

[0041] The rigid connection 1100 is used for installation and fixation by connecting bolts, and can be easily drilled, which can improve the convenience of installation; the flexible connection 1200 can generate flexible deformation, and can easily adjust the relative position of the two rigid connection parts 1100, thereby adapting to installation applications in complex environments.

[0042] Here, the embodiments of this application do not limit the specific structural forms of the rigid connecting part 1100 and the flexible connecting part 1200 described above. In practical applications, those skilled in the art can make the settings according to specific needs. For example, the rigid connecting part 1100 can be a copper plate, while the flexible connecting part 1200 can be a copper braided wire.

[0043] It is understood that, in addition to the rigid-flexible combined plate mentioned above, in some other implementations of the embodiments of this application, the connecting component 1000 can also be entirely set as a rigid connecting part 1100, or the connecting component 1000 can also be entirely set as a flexible connecting part 1200, as long as it can meet the requirements of use.

[0044] In some implementations, it is still as follows Figure 1 As shown, the rigid connection part 1100 may also be provided with a first through hole 1110 and a threaded hole 1120. The functions of the first through hole 1110 and the threaded hole 1120 will be explained later. The threaded hole 1120 can be a through hole or a blind hole. In short, it can be provided with the required internal thread on its inner peripheral wall.

[0045] Please refer to Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of a connecting bolt; Figure 3 This is a schematic diagram of another type of connecting bolt.

[0046] In some implementations, such as Figure 2 As shown, the connecting bolt 2100 may include a head 2110 and a shank 2120, the shank 2120 being able to pass through the aforementioned first through hole 1110.

[0047] In detail, the rod portion 2120 may include a thick neck section 2121 and a first thin neck section 2122. The thick neck section 2121 is located away from the head 2110 relative to the first thin neck section 2122, and the thick neck section 2121 may be provided with external threads. The outer diameter of the thick neck section 2121 may be less than or equal to the inner diameter of the first through hole 1110. In actual installation, the thick neck section 2121 may also pass through the first through hole 1110 for threaded connection with the mounting module.

[0048] The rod portion 2120 may have a stepped surface 2123 formed between the thick neck section 2121 and the first thin neck section 2122. The stepped surface 2123 may be an annular surface, and the stepped surface 2123 may be oriented towards the head 2110. The stepped surface 2123 may be a plane, or it may be a conical surface, which is not limited here.

[0049] In this implementation, the shank 2120 of the connecting bolt 2100 only includes a thick neck section 2121 and a first thin neck section 2122. The external thread can be directly set in the thick neck section 2121, so that the overall structure of the connecting bolt 2100 can be relatively simple.

[0050] It is understood that the above description of the specific structural form of the connecting bolt 2100 is only a combination of the embodiments of this application. Figure 2 This is an exemplary description and should not be construed as limiting the scope of the connecting module and the non-detachable bolt component provided in the embodiments of this application. In some other implementations of the embodiments of this application, the connecting bolt 2100 may also adopt other structural forms, as long as they can meet the requirements of use. For example, see... Figure 3 The rod portion 2120 may further include a second narrow neck section 2124, which may be located on the side of the thick neck section 2123 facing away from the first narrow neck section 2122. In this implementation, the stepped surface 2123 may still be formed between the thick neck section 2121 and the first narrow neck section 2122, and the stepped surface 2123 may still be an annular surface, while the external thread may be provided on the second narrow neck section 2124. For example, the rod portion 2120 may include a rod body, and the outer wall surface of the rod body may be provided with at least one protrusion, the side of which faces the head 2110 may be the aforementioned stepped surface 2123. In this implementation, since the protrusion is not annular, the stepped surface 2123 is no longer an annular surface.

[0051] In some implementations, such as Figure 2 and Figure 3 As shown, the non-detachable bolt component 2000 may also include a first washer 2300.

[0052] The first washer 2300 and the rod portion 2120 may be located on the same side of the head 2110, and the first washer 2300 may be sleeved onto the rod portion 2120. Specifically, the first washer 2300 may be a flat washer, a spring washer, a disc washer, etc. The first washer 2300 is mainly used to increase the contact area, distribute stress, and reduce loosening.

[0053] For the same connecting bolt 2100, the number of first washers 2300 used can be one, or at least two, without limitation.

[0054] Please refer to Figures 4-12 , Figure 4 This is a structural schematic diagram of a limiting component; Figure 5 This is a split structural diagram of the connecting bolts and the limiting components; Figure 6 This is a split structure diagram of the non-detachable bolt component; Figure 7 This is an assembly diagram of a component with non-detachable bolts; Figure 8 This is a schematic diagram of a connection module. Figure 9 This is a structural diagram of the connecting module and the mounting module, where the connecting bolts connect to the mounting module; Figure 10 for Figure 9 A diagram showing the relative positions of the connecting bolts and connecting components; Figure 11 This is a structural diagram of the connecting module and the mounting module, in which the connecting bolts are detached from the mounting module; Figure 12 for Figure 11 Diagram showing the relative positions of the connecting bolts and connecting components.

[0055] like Figures 4-8 As shown in the embodiment of this application, the non-detachable bolt component 2000 further includes a limiting member 2200. The limiting member 2200 is used to connect with the connecting component 1000 so that the limiting member 2200 can be fixed relative to the connecting component 1000. Furthermore, the limiting member 2200 can abut against the stepped surface 2123.

[0056] The connecting bolt 2100 can be in a connected state or a loose state.

[0057] Combination Figure 9 and Figure 10 In the connected state, the connecting bolt 2100 can be connected to the mounting module 200, and the connecting component 1000 can be pressed against the mounting module 200 through the head 2110. At this time, the stepped surface 2123 and the limiting member 2200 can be spaced apart along the axial direction of the connecting bolt 2100.

[0058] Combination Figure 11 and Figure 12In the loosened state, the connecting bolt 2100 can disengage from the mounting module 200. At this time, the limiting member 2200 can abut against the step surface 2123 to limit the connecting bolt 2100, so that the connecting bolt 2100 will not disengage from the connecting component 1000. This can largely avoid the situation where the connecting bolt 2100 falls off and cannot be found, as well as the abnormal noise and safety hazards caused by it.

[0059] In some implementations, such as Figure 6 and Figure 7 As shown, the non-detachable bolt component 2000 may also include a fixing bolt 2400.

[0060] Combination Figure 4 The limiting member 2200 may also be provided with a second through hole 2212. During installation, the second through hole 2212 can be positioned opposite to the aforementioned threaded hole 1120. The fixing bolt 2400 is configured to pass through the second through hole 2212 and connect to the threaded hole 1120, so that the limiting member 2200 is pressed against the connecting member 1000 by bolt connection. In this implementation, the assembly and disassembly of both the limiting member 2200 and the connecting member 1000 are relatively easy, allowing for convenient installation and replacement of the limiting member 2200.

[0061] In specific implementation, the non-detachable bolt component 2000 may also include a second washer 2500, which may be used in conjunction with the fixing bolt 2400. The specific type and usage of the second washer 2500 may be consistent with the aforementioned first washer 2300, and will not be repeated here.

[0062] It is understood that in some other implementations of the embodiments of this application, the limiting member 2200 and the connecting member 1000 can also be connected and fixed by other connection methods, as long as the requirements of use can be met; it should be noted that when the limiting member 2200 is not installed and fixed by the fixing bolt 2400, the aforementioned threaded hole 1120 does not need to be provided. For example, the limiting member 2200 and the connecting member 1000 can also be connected and fixed by snap-fit, riveting, welding, bonding and other connection methods.

[0063] In some implementations, the limiting member 2200 may be located on the side of the connecting member 1000 facing the head 2110.

[0064] Combination Figure 10By adopting the above scheme, when the connecting bolt 2100 is in the connected state, the gap between the stepped surface 2123 and the limiting member 2200 can be at least partially located in the first through hole 1110, and the axial dimension of the connecting bolt 2100 can be relatively small, which is beneficial to reducing the manufacturing and use cost of the connecting bolt 2100. Furthermore, in the above-mentioned connected state, the connecting bolt 2100 can also press the limiting member 2200 with its head 2110, which can further improve the connection reliability of the limiting member 2200.

[0065] It is understood that in some other implementations of the embodiments of this application, the limiting member 2200 may also be located on the side of the connecting member 1000 away from the head 2110. In this case, the axial dimension of the connecting bolt 2100 may be relatively long. In the connected state, the head 2110 may press the connecting member 1000, and the connecting member 1000 may press the limiting member 2200.

[0066] In some implementations, such as Figures 4-6 As shown, the limiting member 2200 may include at least two limiting portions 2210.

[0067] Each limiting part 2210 can be connected to the connecting member 1000. Furthermore, the stepped surface 2123 of the same connecting bolt 2100 can abut against at least two limiting parts 2210. In this way, the limiting member 2200 can limit the abutment of the connecting bolt 2100 at different positions in the direction surrounding the rod 2120, which can improve the reliability of the abutment and limit, and thus further prevent the connecting bolt 2100 from falling off the connecting member 1000.

[0068] Each limiting part 2210 may be provided with a relief groove 2211, which is used to avoid the rod part 2120, so that more area in the limiting part 2210 can be arranged close to the rod part 2120, thereby achieving better contact and limiting of the step surface 2123. Along the axial direction of the rod part 2120, the projection of the bottom wall of the relief groove 2211 can be located on the step surface 2123. In this way, all the plate segments in the limiting part 2210 used to form the relief groove 2211 can abut against the step surface 2123, which can increase the contact area between the limiting part 2210 and the step surface 2123, thereby improving the contact reliability between the limiting part 2210 and the step surface 2123.

[0069] The aforementioned clearance groove 2211 can be an arc-shaped groove, or it can be a V-shaped groove, U-shaped groove, or other shapes of groove. There are no limitations on this, as long as it can meet the requirements of use.

[0070] Combination Figure 4Each limiting portion 2210 that abuts against the stepped surface 2123 of the same connecting bolt 2100 can abut against each other sequentially in the direction surrounding the same connecting bolt 2100. In this way, in the direction surrounding the same connecting bolt 2100, two adjacent limiting portions 2210 can form an abutment limit against each other, reducing the swaying of each limiting portion 2210, and allowing for connection and fixation of each limiting portion 2210 using a smaller number of fixing bolts 2400. For example, see... Figure 6 and Figure 7 Each limiting part 2210 only needs to be installed and fixed by a single fixing bolt 2400, so the structure can be relatively simple.

[0071] In each limiting part 2210 that abuts against the stepped surface 2123 of the same connecting bolt 2100, the bottom wall surfaces of the clearance grooves 2211 of two adjacent limiting parts 2210 can be connected in the direction surrounding the same connecting bolt 2100. In this way, at various positions in the direction surrounding the same connecting bolt 2100, there can be abutment between the limiting part 2210 and the stepped surface 2123, which can greatly improve the reliability of the abutment and limiting of the connecting bolt 2100.

[0072] It is understood that the above description of the specific structural form of the limiting member 2200 is merely an exemplary illustration made in conjunction with the accompanying drawings of the embodiments of this application, and should not be construed as limiting the scope of implementation of the connecting module 100 and the non-detachable bolt component 2000 provided in the embodiments of this application. In some other implementations of the embodiments of this application, the limiting member 2200 may also adopt other structural forms. For example, the limiting part 2210 may not be provided with the clearance groove 2211. For another example, in the direction surrounding the same connecting bolt 2100, two adjacent limiting parts 2210 may be spaced apart. For another example, in the direction surrounding the same connecting bolt 2100, the bottom wall surfaces of the clearance grooves 2211 of two adjacent limiting parts 2210 may not be connected to each other. For another example, along the axial direction of the connecting bolt 2100, the projection of the bottom wall surface of the clearance groove 2211 may only be partially located on the step surface 2123. For another example, the limiting member 2200 may also include only one limiting part 2210.

[0073] This application embodiment also provides a non-detachable bolt component 2000, including a connecting bolt 2100 and a limiting member 2200. The limiting member 2200 is installed on the connecting component 1000. The connecting bolt 2100 is used to connect the connecting component 1000 to the mounting module 200. The limiting member 2200 is also used to limit the connecting bolt 2100 when it is detached from the mounting module 200, so as to prevent the connecting bolt 2100 from falling off the connecting component 1000.

[0074] The specific structural forms of the connecting bolt 2100 and the limiting component 2200 can be referred to the aforementioned implementation methods, and will not be repeated here.

[0075] In this embodiment, the non-detachable bolt component 2000 only requires the addition of a limiting member 2200 to achieve the anti-detachment design for the connecting bolt 2100. The structure is relatively simple and the cost is low. Furthermore, the connecting bolt 2100 is not fixed to the connecting component 1000; therefore, if the connecting bolt 2100 suffers damage such as stripping, only the connecting bolt 2100 needs to be replaced, without replacing the entire connecting module 100, thus keeping the operating cost of the connecting module 100 relatively low.

[0076] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
