Description

Technical Field

[0001] This utility model relates to the field of electrical maintenance technology, specifically to a hoisting fixture for electrical modules. Background Technology

[0002] Electrical modules are installed in electrical cabinets. When maintenance is required, they must be removed from the cabinet. However, in outdoor work sites (such as sandy or rocky ground), uneven ground makes it difficult to operate forklifts or install hoisting equipment stably. This forces operators to manually support the weight of the electrical modules and move them to temporary support points next to the electrical equipment before performing maintenance. While manual handling is manageable when the modules are low, higher modules require additional support, resulting in poor operational stability and safety hazards. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a hoisting fixture for electrical modules, which can hoist electrical modules on uneven ground using the existing structure on the top of the electrical cabinet, and the fixture structure is stable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical solution one relates to a hoisting fixture for an electrical module, wherein the electrical module is installed in an electrical cabinet, and the top of the electrical cabinet has a vertically spaced crossbeam and a support body on at least one side along a first direction. The crossbeam extends along a second direction perpendicular to the first direction and is higher than the support body. The hoisting fixture has a support base and a first latching part, a second latching part, and a hoisting part fixed to the support base. The first latching part is configured to abut against the inner side and bottom surface of the crossbeam, and the second latching part is configured to abut against the outer side and top surface of the support body. The hoisting part is used to hang the electrical module.

[0006] Technical Solution 2 based on Technical Solution 1: The height of the hoisting part is configured such that it is higher than the crossbeam when the first and second locking parts are installed in place.

[0007] Technical solution three based on technical solution two: The supporting base is provided with a first connecting part, which is configured to extend upward at an angle when the first snap-fit ​​part and the second snap-fit ​​part are installed in place; the first snap-fit ​​part and the hoisting part are respectively located at both ends of the first connecting part.

[0008] Technical Solution 4 based on Technical Solution 3: The supporting base is further provided with a second connecting part and a third connecting part; a connecting section is provided in the middle of the first connecting part; when the first snap-fit ​​part and the second snap-fit ​​part are installed in place, the second connecting part extends vertically and its two ends are respectively connected to the first snap-fit ​​part and the second snap-fit ​​part, and the third connecting part extends obliquely upward and its two ends are respectively connected to the second snap-fit ​​part and the connecting section.

[0009] Technical solution five based on technical solution four: The supporting base is further provided with two reinforcing parts; the first snap-fit ​​part extends along the second direction, the extension direction of the first connecting part is perpendicular to the second direction, the two reinforcing parts are symmetrically arranged on both sides of the first connecting part along the second direction, and the two ends of each reinforcing part are respectively connected to the connecting section and the end of the first snap-fit ​​part.

[0010] Technical Solution Six based on Technical Solution Five: The hoisting fixture includes a first support frame and a second support frame. The first support frame is provided with a first snap-fit ​​part, a hoisting part, a first connecting part, and two reinforcing parts. The second support frame is provided with a second snap-fit ​​part, a second connecting part, and a third connecting part. The connecting section of the first connecting part is inserted into the third connecting part, and the second connecting part is inserted into the first snap-fit ​​part.

[0011] Technical solution seven based on technical solution six: the second snap-fit ​​portion extends along the second direction and its length along the second direction is less than the length of the first snap-fit ​​portion along the second direction.

[0012] Technical solution eight based on technical solution six: The second support frame is further provided with a fourth connecting part, the fourth connecting part connecting the upper ends of the second connecting part and the third connecting part and being adapted to abut against the bottom surface of the first connecting part.

[0013] Technical solution nine based on technical solution six: the second connecting part is a C-shaped channel steel structure and the area of ​​the C-shaped channel steel opening is smaller than the area of ​​the bottom of the channel. The bottom of the first snap-fit ​​part is provided with a first insert block extending vertically and adapted to the inner cavity of the second connecting part. The bottom of the connecting section is provided with a second insert block extending vertically. The upper end of the third connecting part is provided with a slot extending vertically.

[0014] Technical solution ten based on technical solution one: Both the first snap-fit ​​part and the second snap-fit ​​part are L-shaped structures.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] In technical solution one, the support body can be either a beam or a plate, and it has an outer surface and a top surface. When the electrical module needs maintenance, a hoisting fixture is first installed on top of the electrical cabinet. During installation, the support base is held by hand, and the first locking part is inserted obliquely into the vertical gap between the beam and the support body. Then, the support base is pressed down, causing it to rotate until the first locking part abuts against the inner and bottom surfaces of the beam, and the second locking part abuts against the outer and top surfaces of the support body. The electrical module is then pulled out of the electrical cabinet and mounted on the hoisting fixture, which lowers the module. After replacing the electrical module, it is mounted on the hoisting fixture and transported to the corresponding position before being installed back into the electrical cabinet. This completes the electrical module replacement operation. After replacement, by lifting the support base upwards, the support base rotates in the opposite direction, causing the first locking part to disengage from the inner side of the crossbeam. Then, by pulling the support base outwards, the second locking part disengages from the support body, and the lifting fixture can be disassembled. It can be seen that the installation and disassembly of the lifting fixture are relatively convenient and labor-saving.

[0017] In uneven outdoor work sites such as sandy or gravelly areas, traditional lifting forklifts or hoisting equipment cannot be stably deployed. This technical solution creatively utilizes the existing structure at the top of the electrical cabinet (vertically distributed beams and supports) as a load-bearing foundation. Through double contact between the first locking part and the inner and bottom surfaces of the beams, and double contact between the second locking part and the outer and top surfaces of the support, a four-way rigid constraint (inside and outside in the first direction, and up and down in the vertical direction) is formed. This eliminates the need for external mobile equipment or ground support, completely overcoming terrain limitations. The hoisting fixture achieves this through four... The surface contact achieves positioning, creating a stable suspension fulcrum for the lifting components (such as lifting rings and hooks) directly above the electrical module. When the electrical module is mounted on top of another electrical module, its weight pulls the supporting base outwards, causing the first locking part to rotate slightly outwards and the second locking part to rotate slightly inwards. This increases the normal pressure between the first locking part and the inner and bottom surfaces of the crossbeam, as well as the normal pressure between the second locking part and the outer and top surfaces of the support body, creating a tightening wedge-shaped constraint effect. This ensures the stability of the lifting fixture when assisting the electrical module. Operators can use lightweight tools such as hand-operated hoists and pulley systems attached to the lifting components to hang the electrical module, reducing the manual weight of the module. This is especially suitable for high-positioned electrical modules (such as those installed near the top of a cabinet), avoiding the risk of weight imbalance when climbing and raising the module, reducing maintenance accident rates, and allowing for single-person operation, significantly reducing maintenance costs.

[0018] In technical solution two, the height of the hoisting unit is higher than the crossbeam when installed, forming a high-level suspension fulcrum. This facilitates unobstructed operation of the hoisting unit above the cabinet top, avoiding interference between the hoisting ropes or electrical modules and the cabinet top structure (such as the crossbeam) during hoisting, ensuring the removal of electrical modules, and facilitating the hoisting of electrical modules near the cabinet top. Furthermore, the higher suspension fulcrum generates a greater torque due to the weight of the electrical modules, resulting in greater contact pressure between the first locking part and the crossbeam, and between the second locking part and the support body. This creates a tighter wedge-shaped constraint effect, further improving the stability of the hoisting fixture under load.

[0019] In technical solution three, the support base is provided with a first connecting part that extends upward at an inclination. The first snap-fit ​​part and the hoisting part are located at its two ends. The inclination of the first connecting part is conducive to forming a more effective force transmission path, reducing bending stress, improving the strength and durability of the support base, and within the design angle range (such as 35-50°), it can guide the tooling to automatically calibrate the horizontal position of the hoisting point during installation, reducing manual adjustment time.

[0020] In technical solution four, the first, second, and third connecting parts form a triangular stable system, constituting a space truss structure. The second connecting part (vertical) bears shear force and some compressive stress, while the third connecting part (inclined) provides an additional tension / compression transmission path, creating a redundant design that enhances reliability, effectively distributes loads, and improves overall stiffness and strength (especially bending and torsional resistance). Simultaneously, the truss structure reduces the weight of the tooling, facilitating manual transport to the vicinity of the electrical cabinet on uneven outdoor work sites such as sandy or gravelly ground. Furthermore, the connection between the third and first connecting parts at the middle section further helps avoid interference with the hoisting of the electrical modules.

[0021] In technical solution five, the symmetrical reinforcing section and the connecting section form a double-triangular stable system, which significantly improves torsional resistance and bending strength. Especially when the electrical module is hoisted off-center (not at the center of the tooling), it can effectively suppress the torsional deformation of the tooling. The reinforcing section connects the connecting section and the end of the first snap-fit ​​section, which distributes the load more evenly to the first snap-fit ​​section (especially along the second direction) and avoids stress concentration.

[0022] In technical solution six, the connecting section of the first connecting part and the third connecting part are plugged into each other, and the second connecting part and the first snap-fit ​​part are plugged into each other, making the assembly and disassembly of the first and second support frames simple and convenient, requiring no additional tools. The separate design of the first and second support frames helps maintain a small volume during lifting and transportation, facilitating transport to narrow or irregular work sites. Furthermore, when the spacing between the crossbeam and the support body is inconsistent, only the second support frame needs to be replaced (by adjusting the lengths of the second and third connecting parts) to adapt to different cabinet types, enhancing versatility. Simultaneously, in case of partial damage, only the corresponding support frame needs to be replaced, reducing maintenance costs.

[0023] In technical solution seven, the length of the second snap-fit ​​part is shorter than that of the first snap-fit ​​part, which is more conducive to making the second support frame occupy a smaller volume, thereby reducing the overall weight of the tooling and making it easier to carry. Despite its smaller size, the second snap-fit ​​part can still fully contact the outer side and top surface of the support body, ensuring sufficient contact area and restraint force.

[0024] In technical solution eight, the fourth connecting part forms an additional connecting node, making the second support frame a closed triangular frame, thus making the structure more stable. The fourth connecting part abuts against the bottom surface of the first connecting part, providing support for the insertion part and preventing loosening or deformation at the insertion point. This ensures connection stability, especially under heavy loads, and improves overall strength. This structure ensures that the second support frame itself has sufficient rigidity after separation and is further locked in place by contact with the first support frame.

[0025] In technical solution nine, the second connecting part is a C-shaped channel steel structure, and the area of ​​the slot opening of the C-shaped channel steel is smaller than the area of ​​the slot bottom. The bottom of the first snap-fit ​​part is provided with a first insert block extending vertically and adapted to the inner cavity of the second connecting part. This fully utilizes the structure of the second connecting part itself to form a slot. The design of the small slot opening and large slot bottom of the C-shaped channel steel ensures that the insert block is laterally restricted (locked) after insertion, providing additional mechanical interlocking. The vertical insertion ensures that the two support frames are accurately positioned after connection and will not produce horizontal deviation.

[0026] In technical solution ten, both the first and second snap-fit ​​parts are L-shaped structures. The L-shaped structure can be made by simply bending metal plates (or cutting profiles), resulting in low processing costs. The two vertical surfaces of the L-shape can simultaneously fit tightly against the inner / bottom (or outer / top) surface of the crossbeam, providing stable double-sided constraint.

[0043] See Figure 1-2 , Figure 1-2 A schematic diagram is shown of a hoisting fixture 100 for an electrical module being installed on an electrical cabinet 10. The electrical module (not shown) is installed in the electrical cabinet 10. Exemplarily, the electrical module can be pulled out into the installation channel 11 of the electrical cabinet 10 along a first direction. The top of the electrical cabinet 10 is provided with a vertically spaced crossbeam 12 and a support body 13 on at least one side along the first direction. The crossbeam 12 extends along a second direction perpendicular to the first direction and is higher than the support body 13. It should be understood that when both ends of the installation channel 11 are open along the first direction, the crossbeam 12 and the support body 13 can be provided on both sides of the top of the electrical cabinet 10 along the first direction. When only one end of the installation channel 11 is open along the first direction, the crossbeam 12 and the support body 13 are provided on the same side as the open side of the installation channel 11. The crossbeam 12 is a strip-shaped beam with standard geometric features, having a horizontal bottom surface and a vertical inner surface facing into the cabinet. The support 13 can be in the form of a crossbeam or a support plate, having a vertical outer surface facing outwards from the cabinet and a horizontal top surface. The structures of the crossbeam 12 and the support 13 can be the same or different. It should be understood that in this embodiment, the first direction and the second direction can be the length direction and the width direction of the electrical cabinet 10, respectively. The vertical direction is parallel to the direction of gravity, with the base mounting plane of the electrical cabinet 10 as the reference, and the horizontal plane is the plane parallel to the base plane.

[0044] See Figure 1The hoisting fixture 100 is provided with a support base 20 and a first latching part 31, a second latching part 32, and a hoisting part 33 fixed to the support base 20; see also Figure 3-6 The first latching part 31 is configured to abut against the inner side and bottom surface of the crossbeam 12, and the second latching part 32 is configured to abut against the outer side and top surface of the support body 13. Both the first latching part 31 and the second latching part 32 are L-shaped structures and extend along a second direction. The length of the second latching part 32 along the second direction is less than the length of the first latching part 31 along the second direction. In this embodiment, the horizontal section of the L-shaped structure of the first latching part 31 is in the form of a reinforcing beam to form higher strength. The lifting part 33 is used to hang the electrical module. The lifting part 33 can be a structure such as a lifting ring, a hook, or a through hole. In practical applications, it can be connected to a lifting tool such as a hand chain hoist 60 to lift the electrical module.

[0045] See Figure 6-7 The support base 20 also includes a first connecting portion 34, a second connecting portion 35, a third connecting portion 36, a fourth connecting portion 37, and two reinforcing portions 38. The first connecting portion 34 is configured to extend upwards at an angle when the first engaging portion 31 and the second engaging portion 32 are in place; the first engaging portion 31 and the lifting portion 33 are respectively located at both ends of the first connecting portion 34. See also... Figure 1 The height of the hoisting part 33 is higher than the crossbeam 12 when the first snap-fit ​​part 31 and the second snap-fit ​​part 32 are installed in place.

[0046] See also Figure 6-7 The first connecting portion 34 extends perpendicularly to the second direction, and a connecting section 341 is provided in the middle of the first connecting portion 34. When the first snap-fit ​​portion 31 and the second snap-fit ​​portion 32 are installed in place, the second connecting portion 35 extends vertically and its two ends are respectively connected to the first snap-fit ​​portion 31 and the second snap-fit ​​portion 32. The third connecting portion 36 extends obliquely upward and its two ends are respectively connected to the second snap-fit ​​portion 32 and the connecting section 341. Similarly, the extending direction of the third connecting portion 36 is perpendicular to the second direction. The fourth connecting portion 37 connects the upper ends of the second connecting portion 35 and the third connecting portion 36 and is adapted to abut against the bottom surface of the first connecting portion 34. Two reinforcing portions 38 are symmetrically arranged on both sides of the connecting portion along the second direction, and the two ends of each reinforcing portion 38 are respectively connected to the end of the connecting section 341 and the end of the first snap-fit ​​portion 31.

[0047] In this embodiment, see Figure 8The lifting fixture 100 adopts a split design, comprising a first support frame 40 and a second support frame 50. The first support frame 40 is provided with the aforementioned first locking part 31, lifting part 33, first connecting part 34, and two reinforcing parts 38. The second support frame 50 is provided with the aforementioned second locking part 32, second connecting part 35, third connecting part 36, and fourth connecting part 37. For the connection between the first support frame 40 and the second support frame 50, see [reference needed]. Figure 6 The connecting section 341 of the first connecting part 34 is inserted into the third connecting part 36, and the second connecting part 35 is inserted into the first snap-fit ​​part 31. The first connecting part 34, the second connecting part 35, the third connecting part 36, the fourth connecting part 37, and the two reinforcing parts 38 are all C-shaped channel steel structures, with the area of ​​the channel opening smaller than the area of ​​the channel bottom. The bottom of the first snap-fit ​​part 31 has a first insert 311 extending vertically and adapted to the inner cavity of the second connecting part 35. The bottom of the connecting section 341 has a second insert 342 extending vertically. The upper end of the third connecting part 36 has a slot 361 extending vertically. When the first support frame 40 and the second support frame 50 are inserted into place, the portion excluding the first snap-fit ​​part 31, the second snap-fit ​​part 32, and the lifting part 33 forms the support base 20. When the lifting fixture adopts a split design (i.e., including the first support frame 40 and the second support frame 50), in addition to the plug-in method, the two can also be fixed by other means, such as bolt locking, magnetic fixing, and rotating buckle fixing. It should be noted that those skilled in the art can flexibly select or combine the above connection methods according to actual working conditions (such as load-bearing capacity, frequency of disassembly and assembly, environmental corrosivity, etc.) without departing from the core utility model concept of this application. Such modifications should be considered to fall within the protection scope of this application.

[0048] It should be understood that in other embodiments, the lifting fixture 100 may also be an integral structure.

[0049] In this embodiment, when the electrical module needs maintenance, a hoisting fixture 100 is first installed on the top of the electrical cabinet 10. During installation, the support base 20 is held by hand, and the first snap-fit ​​part 31 is inserted obliquely into the vertical gap between the crossbeam 12 and the support body 13. Then, the support base 20 is pressed down, causing it to rotate until the first snap-fit ​​part 31 abuts against the inner and bottom surfaces of the crossbeam 12, and the second snap-fit ​​part 32 abuts against the outer and top surfaces of the support body 13. The electrical module is then pulled out of the installation channel 11 and hung on the hoisting part 33, which lowers the electrical module. After replacing the electrical module, it is hung on the hoisting part 33 and transported to the corresponding installation channel 11 via the hoisting part 33, before being pushed into the installation channel 11. In this way, the replacement operation of the electrical module is completed. After replacement, by lifting the support base 20 upwards, the support base 20 rotates in the opposite direction, causing the first locking part 31 to disengage from its contact with the inner side of the crossbeam 12. Then, by pulling the support base 20 outwards, the second locking part 32 disengages from its contact with the support body 13, and the lifting fixture 100 can be disassembled. It can be seen that the installation and disassembly of the lifting fixture 100 are relatively convenient and labor-saving.

[0050] In uneven outdoor work sites such as sandy or gravelly areas, traditional lifting forklifts or hoisting equipment cannot be stably deployed. This technical solution creatively utilizes the existing structure at the top of the electrical cabinet 10 (vertically distributed crossbeams 12 and support bodies 13) as a load-bearing foundation. Through the double contact of the first locking part 31 with the inner and bottom surfaces of the crossbeams 12, and the double contact of the second locking part 32 with the outer and top surfaces of the support bodies 13, a four-way rigid constraint (inside and outside in the first direction, and up and down in the vertical direction) is formed. This eliminates the need for external mobile equipment or ground support, completely overcoming terrain limitations. The hoisting fixture 100... The four-sided contact achieves positioning, allowing the lifting part 33 (such as lifting rings and hooks) to form a stable suspension fulcrum directly above the electrical module. When the electrical module is mounted on the electrical module, the weight of the electrical module pulls the supporting base 20 outward, causing the first locking part 31 to rotate slightly outward and the second locking part 32 to rotate slightly inward. This increases the positive pressure between the first locking part 31 and the inner and bottom surfaces of the crossbeam 12, and simultaneously increases the positive pressure between the second locking part 32 and the outer and top surfaces of the support body 13, forming a wedge-shaped constraint effect that tightens as it is pulled, thus ensuring the stability of the lifting fixture 100 when assisting the electrical module. Operators can use lightweight tools such as hand-operated hoists 60 and pulley blocks attached to the lifting part 33 to hang the electrical module, thereby reducing the weight of the module that needs to be supported manually. This is especially suitable for high-positioned electrical modules (such as those installed near the top of the cabinet), avoiding the risk of imbalance of the operator's center of gravity when climbing and raising the module, reducing the maintenance accident rate, and allowing for operation by a single person, significantly reducing maintenance costs.

[0051] In this embodiment, the height of the hoisting part 33 is higher than that of the crossbeam 12 when it is installed in place, forming a high-level suspension support point. This facilitates the creation of an unobstructed operating space for the hoisting part 33 above the cabinet top, avoiding interference between the hoisting ropes or electrical modules and the cabinet top structure (such as the crossbeam 12) during hoisting, ensuring the removal of electrical modules, and facilitating the hoisting of electrical modules near the cabinet top. In addition, the torque generated by the weight of the electrical modules at the high-level suspension support point is greater, resulting in greater contact pressure between the first locking part 31 and the crossbeam 12, and between the second locking part 32 and the support body 13. This is more conducive to forming a tighter wedge-shaped constraint effect, further improving the stability of the hoisting fixture 100 under load.

[0052] In this embodiment, the support base 20 is provided with a first connecting part 34 extending upward at an incline, and the first snap-fit ​​part 31 and the hoisting part 33 are respectively located at its two ends. The inclined first connecting part 34 is conducive to forming a more effective force transmission path, reducing bending stress, improving the strength and durability of the support base 20, and within the design angle range such as (35-50°), it can guide the tooling to automatically calibrate the horizontal position of the hoisting point of the hoisting part 33 during installation, reducing manual adjustment time.

[0053] In this embodiment, the first connecting part 34, the second connecting part 35, and the third connecting part 36 form a triangular stable system, constituting a spatial truss structure. The second connecting part 35 (vertical) bears shear force and part of the compressive force, while the third connecting part 36 (inclined) provides an additional tension / compression transmission path, creating a redundant design, enhancing reliability, effectively distributing loads, and improving overall stiffness and strength (especially bending and torsional resistance). Simultaneously, the truss structure reduces the weight of the tooling, facilitating manual transport to the vicinity of the electrical cabinet 10 on uneven outdoor work sites such as sandy or gravelly ground. Furthermore, the connection between the third connecting part 36 and the connecting section 341 in the middle of the first connecting part 34 further helps avoid interference with the hoisting of the electrical module.

[0054] In this embodiment, the symmetrical reinforcing part 38 and the connecting part form a double-triangular stable system, which significantly improves the torsional resistance and bending strength. Especially when the electrical module is hoisted off-center (not in the center of the tooling), it can effectively suppress the torsional deformation of the tooling. The reinforcing part 38 connects the connecting section 341 and the end of the first snap-fit ​​part 31, so as to distribute the load more evenly to the first snap-fit ​​part 31 (especially along the second direction) and avoid stress concentration.

[0055] In this embodiment, the connecting section 341 of the first connecting part 34 is inserted into the third connecting part 36, and the second connecting part 35 is inserted into the first snap-fit ​​part 31, making the assembly and disassembly of the first support frame 40 and the second support frame 50 simple and convenient, without the need for additional tools. The separate design of the first support frame 40 and the second support frame 50 helps to maintain a small volume during the transportation of the hoisting fixture 100, making it easy to carry to narrow or irregular work sites. Moreover, when the spacing between the crossbeam 12 and the support body 13 is inconsistent, only the second support frame 50 needs to be replaced (by adjusting the lengths of the second connecting part 35 and the third connecting part 36) to adapt to different cabinet types, enhancing versatility. At the same time, in case of partial damage, only the corresponding support frame needs to be replaced, reducing maintenance costs.

[0056] In this embodiment, the length of the second latching portion 32 is less than the length of the first latching portion 31, which is more conducive to making the second support frame 50 occupy a smaller volume, thereby reducing the overall weight of the tooling and making it more convenient to carry. Despite its smaller size, the second latching portion 32 can still fully contact the outer side and top surface of the support body 13, ensuring sufficient contact area and restraint force.

[0057] In this embodiment, the fourth connecting part 37 forms an additional connecting node, making the second support frame 50 form a closed triangular frame, which makes the structure more stable; the fourth connecting part 37 abuts against the bottom surface of the first connecting part 34, providing support for the insertion part, preventing the insertion part from loosening or deforming, especially maintaining connection stability under heavy load, and improving overall strength; this structure ensures that the second support frame 50 itself has sufficient rigidity after separation, and is further locked by contact with the first support frame 40 when installed in place.

[0058] In this embodiment, the second connecting part 35 is a C-shaped channel steel structure, and the area of ​​the opening of the C-shaped channel steel is smaller than the area of ​​the bottom of the channel. The bottom of the first snap-fit ​​part 31 is provided with a first insert 311 extending vertically and adapted to the inner cavity of the second connecting part 35. The structure of the second connecting part 35 itself is fully utilized to form a slot 361. The design of the small opening and large bottom of the C-shaped channel steel makes the insert laterally restricted (locked) after insertion, providing additional mechanical interlocking. The vertical insertion ensures that the two support frames are accurately positioned after connection and will not produce horizontal deviation.

[0059] In this embodiment, both the first snap-fit ​​portion 31 and the second snap-fit ​​portion 32 are L-shaped structures. The L-shaped structure can be made by simply bending a metal plate (or cutting a profile), resulting in low processing costs. The two vertical surfaces of the L-shape can simultaneously fit tightly against the inner / bottom (or outer / top) surface of the crossbeam, providing stable double-sided constraint.

[0060] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
