Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device. Background Technology

[0002] In data centers, power equipment, and communication equipment, electrical equipment is typically housed in dedicated server racks. Conventional rack mounting methods often employ top or bottom mounting, but these methods are not without their limitations. For example, when the rack's total weight is significant, top mounting relies entirely on the top frame, which has lifting points or holes. Since the top frame is primarily designed to support a lighter top cover rather than bear the overall weight, its structural strength is usually low, and the immense tensile force can lead to permanent deformation or even breakage. Bottom mounting, on the other hand, presents challenges due to the location of the lifting points or holes at the bottom of the rack. Utility Model Content

[0003] In view of this, the present invention provides a new hoisting device to solve the problems existing in the conventional hoisting methods.

[0004] This utility model embodiment provides a rack hoisting device for racking a server rack. The server rack includes a base, and the hoisting device includes four hoisting components. The four hoisting components are configured to connect to two sides opposite to the base, and each of the two sides connects two hoisting components. Each hoisting component includes an installation section and a hoisting section. The installation section is connected to the hoisting section, and the hoisting section has a first hoisting hole. The installation section is configured to connect to the base. Based on the connection between the installation section and the base, the orthographic projection of the first hoisting hole onto a reference plane is located outside the bottom surface of the base. The reference plane is the plane containing the bottom surface of the base.

[0005] In some optional embodiments, the bottom surface of the base is rectangular, and the bottom surface of the base includes a first side and a second side that are perpendicular to each other, the length of the first side being less than that of the second side; in the extending direction of the first side, the distance from the orthographic projection of the first mounting hole onto the bottom surface of the reference plane is greater than zero.

[0006] In some alternative embodiments, each of the lifting assemblies further includes a transition section, through which the lifting section is connected to the mounting section, and an angle exists between the transition section and the mounting section.

[0007] In some optional embodiments, the transition section includes a connecting plate and a plurality of reinforcing ribs. The connecting plate is perpendicular to the bottom surface of the base, and the reinforcing ribs are perpendicular to the connecting plate. The mounting section is connected to the hoisting section via the connecting plate. The reinforcing ribs include a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is located between the connecting plate and the hoisting section and is perpendicularly connected to both the connecting plate and the hoisting section. The second reinforcing rib is located between the connecting plate and the mounting section and is perpendicularly connected to both the connecting plate and the mounting section.

[0008] In some alternative embodiments, the lifting section of each lifting assembly is parallel to the installation section.

[0009] In some alternative embodiments, the hoisting section includes a hoisting plate and a reinforcing plate connected together, the hoisting plate being perpendicular to the bottom surface of the base, and the reinforcing plate being perpendicular to the hoisting plate.

[0010] In some alternative embodiments, the lifting device includes a lifting insert with a second lifting hole, the lifting insert being configured to be detachably mounted on the lifting section; the second lifting hole communicates with the first lifting hole based on the installation of the lifting insert on the lifting section.

[0011] In some alternative embodiments, the lifting device includes a variety of lifting plates, each with a different diameter of the second lifting hole.

[0012] In some alternative embodiments, the lifting device is configured such that the two mounting sections of the two lifting assemblies connected to the same side of the base are an integral structure.

[0013] In some alternative embodiments, the lifting section of each lifting assembly is at an angle to the mounting section.

[0014] In this embodiment of the invention, the rack hoisting device includes four hoisting components. These four components are configured to connect to two sides opposite the base, with two hoisting components connected to each side. Each hoisting component includes an installation section and a hoisting section, connected together. A first hoisting hole is provided on the hoisting section. The installation section is configured to connect to the base. Based on this connection, the orthographic projection of the first hoisting hole onto a reference plane lies outside the bottom surface of the base. The reference plane is the plane containing the bottom surface of the base. Leveraging the base's typically high structural strength as the overall load-bearing component of the rack, the base supports the rack's own weight, preventing permanent deformation and breakage of the rack's structural components. By arranging the four hoisting components on both sides of the base, the hoisting force is evenly distributed across the entire base, preventing damage to the base or rack due to stress concentration. By setting the first lifting hole to be projected onto the bottom surface of the base outside the reference plane, the first lifting hole is exposed outside the cabinet outline. The first lifting hole outside the cabinet outline can be used to conveniently hang lifting hooks or slings, thereby solving the inconvenience of lifting caused by the lifting point or lifting hole being located at the bottom of the cabinet.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction relationship between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] As mentioned earlier, current conventional hoisting methods are not yet perfect. When the total weight of the rack is large, top hoisting relies entirely on the top frame with hoisting points or holes. Since the top frame is primarily designed to support a lighter top cover rather than bear the overall weight, its structural strength is usually low, and the enormous tensile force may cause permanent deformation or even breakage. Bottom hoisting, on the other hand, presents inconvenience due to the location of the hoisting points or holes at the bottom of the rack.

[0028] In this embodiment of the invention, the rack hoisting device includes four hoisting components. These four components are configured to connect to two sides opposite the base, with two hoisting components connected to each side. Each hoisting component includes an installation section and a hoisting section, connected together. A first hoisting hole is provided on the hoisting section. The installation section is configured to connect to the base. Based on this connection, the orthographic projection of the first hoisting hole onto a reference plane lies outside the bottom surface of the base. The reference plane is the plane containing the bottom surface of the base. Leveraging the base's typically high structural strength as the overall load-bearing component of the rack, the base supports the rack's own weight, preventing permanent deformation and breakage of the rack's structural components. By arranging the four hoisting components on both sides of the base, the hoisting force is evenly distributed across the entire base, preventing damage to the base or rack due to stress concentration. By setting the first lifting hole to be projected onto the bottom surface of the base outside the reference plane, the first lifting hole is exposed outside the cabinet outline. The first lifting hole outside the cabinet outline can be used to conveniently hang lifting hooks or slings, thereby solving the inconvenience of lifting caused by the lifting point or lifting hole being located at the bottom of the cabinet.

[0029] The hoisting device provided in this utility model embodiment will be described below with reference to the accompanying drawings. It should be noted that the various drawings in this utility model specification are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this utility model in any way, and are not necessarily drawn to scale.

[0030] like Figure 1-3 As shown, this embodiment of the utility model provides a hoisting device 100 for hoisting a server rack 200, which includes a base 210. The hoisting device 100 includes four hoisting components 110, configured to connect to two sides opposite to the base 210, with each side connecting two hoisting components 110. The base 210 may include a top surface, a bottom surface, and sides. The top surface connects to the cabinet body of the server rack 200, the bottom surface is typically in contact with the ground, and the sides are located between the top and bottom surfaces. The base 210 of the server rack 200 typically bears all the loads of the cabinet body and internal equipment, therefore, the structural strength of the base 210 is usually high. The four hoisting components 110 are configured to connect to two sides opposite to the base 210, allowing the structural strength of the base 210 itself to support the weight of the server rack 200, thus improving the safety and reliability of the hoisting process.

[0031] The hoisting assembly 110 includes an installation section 111 and a hoisting section 112, with the installation section 111 connected to the hoisting section 112. The hoisting section 112 has a first hoisting hole 1121. The installation section 111 is configured to connect to the base 210. Multiple bolt holes may be provided on the installation section 111, and multiple bolt holes may also be provided on the side of the base 210 of the cabinet 200. By using bolts passing through the bolt holes in the installation section 111 and the installation holes on the side of the base 210, the installation section 111 can be detachably connected to the side of the base 210. By detachably connecting the installation section 111 of the hoisting assembly 110 to the base 210, the hoisting assembly 110 can be removed from the base 210 after hoisting, without occupying additional space near the cabinet 200. Furthermore, the disassembled hoisting component 110 can be used for hoisting other cabinets 200, so that one hoisting device 100 can meet the hoisting needs of multiple cabinets 200, effectively reducing the cost of the hoisting device 100.

[0032] Based on the connection between the mounting section 111 and the base 210, the orthographic projection of the first lifting hole 1121 onto the reference plane is located outside the bottom surface of the base 210, where the reference plane is the plane containing the bottom surface of the base 210. That is, the portion of the lifting section 112 with the first lifting hole 1121 extends beyond the space enclosed by the planes containing the sides of the base 210. The bottom surface of the base 210 can be understood as the planar area enclosed by the outer contour of the bottom surface of the base 210. The lifting assembly 110 may include a main body formed by bending a thick steel plate of 10mm, 12mm, or 15mm thickness. The bent section of the main body can constitute the main body of the mounting section 111 and the lifting section 112, and the plate surface of the main body can be perpendicular to the bottom surface of the base 210. Reinforcing ribs or plates perpendicular to the main body can be welded to the main body to enhance the torsional resistance of the lifting assembly 110.

[0033] At least four first lifting holes 1121 can be provided by four lifting assemblies 110. During lifting, a sling can be installed in each lifting hole, or a sling can be installed in every two lifting holes. Alternatively, a lifting rod can be installed in every two lifting holes, with slings connected to both ends of the lifting rod. For specific implementation methods of lifting using slings or lifting rods, please refer to relevant technologies, which will not be elaborated here.

[0034] In this embodiment of the present invention, the hoisting device 100 of the cabinet 200 includes four hoisting components 110. The four hoisting components 110 are configured to connect to two sides opposite to the base 210, with two hoisting components 110 connected to each side. Each hoisting component 110 includes a mounting section 111 and a hoisting section 112. The mounting section 111 is connected to the hoisting section 112, and a first hoisting hole 1121 is provided on the hoisting section 112. The mounting section 111 is configured to connect to the base 210. Based on the connection between the mounting section 111 and the base 210, the orthographic projection of the first hoisting hole 1121 onto a reference plane is located outside the bottom surface of the base 210. The reference plane is the plane containing the bottom surface of the base 210. By utilizing the characteristic that the base 210, as the overall load-bearing component of the cabinet 200, typically has high structural strength, the base 210 of the cabinet 200 can bear the weight of the cabinet 200, preventing permanent deformation and breakage of the structural components of the cabinet 200. By arranging four lifting components 110 on both sides of the base 210, the lifting force can be evenly distributed throughout the base 210, preventing damage to the base 210 or the cabinet 200 due to stress concentration. By setting the first lifting hole 1121 to be located outside the bottom surface of the base 210 in the orthographic projection of the reference plane, the first lifting hole 1121 is exposed outside the outline of the cabinet 200. The first lifting hole 1121 outside the outline of the cabinet 200 allows for convenient attachment of lifting hooks or slings, thereby solving the lifting inconvenience caused by the lifting point or lifting hole being located at the bottom of the cabinet 200.

[0035] like Figure 2 and Figure 3 As shown, in some optional embodiments, the bottom surface of the base 210 is rectangular. The overall outline of the base 210 can be a cube with a height smaller than its length and width. Specifically, the width and length of the base 210 are the side lengths of the bottom surface of the base 210, and the height of the base 210 between its bottom and top surfaces is smaller than its width and length. The bottom surface of the base 210 includes a first side 211 and a second side 212 that are perpendicular to each other, and the length of the first side 211 is smaller than that of the second side 212. In the extending direction of the first side 211, the distance from the orthographic projection of the first lifting hole 1121 onto the bottom surface in the reference plane is greater than zero. The extending direction of the first side 211 can be understood as a direction parallel to the first side 211. The distance from the orthographic projection of the first lifting hole 1121 onto the bottom surface in the reference plane can be understood as the closest distance of that orthographic projection onto the bottom surface.

[0036] The side of the base 210 may include a first side parallel to a first side 211 and a second side parallel to a second side 212. A portion of the lifting section 112 of the lifting assembly 110 with a first lifting hole 1121 may extend to the outer side of the first side of the base 210, such that the distance from the first lifting hole 1121 projected onto the reference plane to the bottom plane in the extending direction of the first side 211 is greater than zero. In some optional embodiments, portions of the lifting sections 112 of two lifting assemblies 110 connected to the same side of the base 210 with the first lifting holes 1121 may extend to the outer sides of two second sides of the base 210, respectively. In other optional embodiments, portions of the lifting sections 112 of two lifting assemblies 110 connected to the same side of the base 210 with the first lifting holes 1121 may both extend to the outer side of the same second side of the base 210.

[0037] In this embodiment of the invention, the bottom surface of the base 210 is rectangular, and includes a first side 211 and a second side 212 that are perpendicular to each other. The length of the first side 211 is less than that of the second side 212. In the extending direction of the first side 211, the distance between the projection of the first lifting hole 1121 onto the reference plane and the bottom surface is greater than zero. By limiting the projection of the first lifting hole 1121 onto the narrower side (first side 211) of the base 210 to a distance greater than zero from the bottom surface of the base 210, the first lifting hole 1121, as a lifting point, extends outward in the narrower side direction of the cabinet 200. This provides a wider supporting torque in the narrower side direction, which is more sensitive to center of gravity stability, effectively counteracting possible swaying or tilting of the cabinet 200 in the narrower side direction. When the cabinet is a narrow cabinet where the first side 211 is less than the second side 212, the stability and safety of the cabinet lifting are effectively improved.

[0038] Optionally, the center of the projection set formed by the orthographic projections of all the first lifting holes 1121 on the reference plane can be located within the bottom surface of the base 210. When a lifting hole is provided on each lifting assembly 110, the orthographic projection points of the four first lifting holes 1121 on the reference plane will form the vertex of a regular geometric shape, such as the vertex of a rectangle, and the geometric center of this geometric shape is the center of the projection set. The base 210 of the cabinet 200 is usually rectangular. In some optional embodiments, the four lifting assemblies 110 can be symmetrically installed on the two opposite sides of the base 210 with the plane between the two opposite sides as the plane of symmetry. Furthermore, the lifting assemblies 110 installed on each of the two opposite sides can be symmetrically arranged about the centerline of that side, so that the first lifting holes 1121 of the two lifting assemblies 110 installed on each side are symmetrically arranged about the centerline of that side. It should be understood that the centerline of the aforementioned side refers to the centerline perpendicular to the bottom surface on that side. With this symmetrical and uniform layout, the center of the projection set formed by the orthographic projection of all the first hoisting holes 1121 on the reference plane will be located inside the bottom surface of the base 210 and will coincide with or be very close to the geometric center of the rectangular bottom surface of the base 210.

[0039] In this embodiment of the invention, the center of the projection set formed by the orthographic projections of all the first lifting holes 1121 on the reference plane is located within the bottom surface of the base 210. This allows the center of the lifting point set formed by all the first lifting holes 1121 to be close to the vertical line where the center of gravity of the cabinet 200 is located when the cabinet 200 is lifted through the first lifting holes 1121. This reduces the torque difference between each first lifting hole 1121 and the center of gravity of the cabinet 200, thereby distributing the weight of the cabinet 200 more evenly to each first lifting hole 1121 and improving the stability of the lifting.

[0040] like Figure 2 As shown, in some optional embodiments, each hoisting assembly 110 further includes a transition section 113. The hoisting section 112 is connected to the mounting section 111 via the transition section 113. An angle exists between the transition section 113 and the mounting section 111, meaning the transition section 113 is not parallel to the mounting section 111. By providing a transition section 113 connected to the mounting section 111 at an angle, the hoisting assembly 110 can be bent at the end of the mounting section 111, guiding the hoisting section 112 from a position close to the side of the cabinet 200 to an open space. This provides greater freedom in the arrangement of the hoisting section 112 and improves the applicability of the hoisting assembly 110. For example, as... Figure 2As shown, there may be a reinforcing plate 1123 at the edge of the side of the base 210 that is perpendicular to the bottom surface. This reinforcing plate 1123 will block the installation component from extending along the side. By setting a transition section 113 that has an angle with the installation section 111, the reinforcing plate 1123 can be bypassed, thereby solving the limitation of the reinforcing plate 1123 on the installation space of the installation component.

[0041] like Figure 2 As shown, in some optional embodiments, the lifting section 112 of each lifting assembly 110 is parallel to the mounting section 111. By setting the lifting section 112 of each lifting assembly 110 to be parallel to the mounting section 111, when the mounting section 111 is connected to two first sides parallel to the first side 211, the lifting section 112 connected to the mounting section 111 can extend along a direction parallel to the first side 211 toward the side of the second side away from the base 210, that is, extend along a direction perpendicular to the second side toward the side of the second side away from the base 210. Compared with lifting pipes in other directions, it is possible to extend a longer distance toward the side of the second side away from the base 210 with the same size, thereby improving the utilization rate of the extended section.

[0042] When the hoisting section 112 of the mounting assembly is parallel to the mounting section 111, the mounting section 111 can be connected to two first sides parallel to the first side 211. Based on the parallelism of the two first sides, the mounting section 111 and the hoisting section 112 connected to the two first sides are also parallel to each other. The mounting assembly connected to the two first sides can be symmetrical about the plane of symmetry of the second side 212, which is a plane perpendicular to the second side 212 and passing through its midpoint. In this case, the hoisting section 112 of the mounting assembly connected to the two first sides extends the same length away from the base 210 relative to the second side. The two lifting sections 112 extending away from the base 210 on the same second side are opposite each other in the direction of extension of the second side 212, and the center line connecting the first lifting holes 1121 on the two lifting sections 112 is parallel to the second side 212. This makes it easier for the same sling or lifting rod to pass through the first lifting holes 1121 on the two lifting sections 112 at the same time, thereby reducing the difficulty of binding the sling or installing the lifting rod during lifting.

[0043] like Figure 2 As shown, in some optional embodiments, the transition section 113 includes a connecting plate 1131 and a plurality of reinforcing ribs. The connecting plate 1131 is perpendicular to the bottom surface of the base 210, and the reinforcing ribs are perpendicular to the connecting plate 1131. The mounting section 111 is connected to the hoisting section 112 through the connecting plate 1131.

[0044] The reinforcing ribs include a first reinforcing rib 1132 and a second reinforcing rib 1133. The first reinforcing rib 1132 is located between the connecting plate 1131 and the hoisting section 112, and is perpendicularly connected to the connecting plate 1131 and the hoisting section 112. The second reinforcing rib 1133 is located between the connecting plate 1131 and the mounting section 111, and is perpendicularly connected to the connecting plate 1131 and the mounting section 111.

[0045] Optionally, the connecting plate 1131 includes a first surface and a second surface. A first reinforcing rib 1132 can be connected to the first surface of the connecting plate 1131 and the lifting section 112, and a second reinforcing rib 1133 can be connected to the second surface of the connecting plate 1131 and the mounting section 111. The first reinforcing rib 1132 and the second reinforcing rib 1133 can be parallel to the bottom surface of the base 210, and the number of both the first reinforcing rib 1132 and the second reinforcing rib 1133 can be two. The two first reinforcing ribs 1132 can be connected to two sides of the first surface of the connecting plate 1131 parallel to the bottom surface of the base 210 to increase the distance between the two first reinforcing ribs 1132 and improve their bending resistance. Similarly, the two second reinforcing ribs 1133 can be connected to two sides of the second surface of the connecting plate 1131 parallel to the bottom surface of the base 210.

[0046] In this embodiment of the invention, the transition section 113 includes a connecting plate 1131 and multiple reinforcing ribs. The connecting plate 1131 is perpendicular to the bottom surface of the base 210, and the reinforcing ribs are perpendicular to the connecting plate 1131. The mounting section 111 is connected to the hoisting section 112 via the connecting plate 1131. The reinforcing ribs include a first reinforcing rib 1132 and a second reinforcing rib 1133. The first reinforcing rib 1132 is located between the connecting plate 1131 and the hoisting section 112, and is perpendicularly connected to both. The second reinforcing rib 1133 is located between the connecting plate 1131 and the mounting section 111, and is perpendicularly connected to both. The first reinforcing rib 1132 and the second reinforcing rib 1133 can enhance the structural strength of the transition section 113, as well as the strength of the connection nodes between the transition section 113 and the mounting section 111, and between the transition section 113 and the hoisting section 112.

[0047] like Figure 2 As shown, in some optional embodiments, the lifting section 112 includes a connected lifting plate 1122 and a reinforcing plate 1123. The lifting plate 1122 is perpendicular to the bottom surface of the base 210, and the reinforcing plate 1123 is perpendicular to the lifting plate 1122. Optionally, the lifting section 112 may include two reinforcing plates 1123 parallel to the bottom surface of the base 210. The two reinforcing plates 1123 are respectively connected to two edges of the lifting plate 1122 that are parallel to the bottom surface of the base 210, forming a channel-shaped or I-shaped lifting section 112.

[0048] In this embodiment of the utility model, by setting the hoisting section 112 including a hoisting plate 1122 and a reinforcing plate 1123 connected together, the hoisting plate 1122 is perpendicular to the bottom surface of the base 210, and the reinforcing plate 1123 is perpendicular to the hoisting plate 1122. Compared with setting only the hoisting plate 1122, the bending stiffness and deformation resistance of the hoisting section 112 can be enhanced, and the local deformation caused by excessive force during hoisting can be effectively prevented.

[0049] like Figure 2 As shown, in some optional embodiments, the lifting structure includes a lifting insert 120 with a second lifting hole 1201, the lifting insert 120 being configured to be detachably mounted on the lifting section 112. Based on the installation of the lifting insert 120 on the lifting section 112, the second lifting hole 1201 communicates with the first lifting hole 1121. The lifting insert 120 can be located between two reinforcing plates 1123, detachably connected to the lifting plate 1122 by bolts. The lifting insert 120 mounted on the lifting plate 1122 can be parallel to the lifting plate 1122, thereby serving as a reinforcing plate for the lifting plate 1122 and increasing the structural strength of the lifting section 112. The orthographic projection of the second lifting hole 1201 onto the lifting insert can be located within the first lifting hole 1121, so that slings or lifting rods passing through the second lifting hole 1201 are not obstructed by the first lifting hole 1121.

[0050] like Figure 2 As shown, the first lifting hole 1121 can be a rectangular hole, and the second lifting hole 1201 can be a circular hole or an oblong hole. Therefore, when using a sling for lifting via the lifting device 100, the sling can be directly installed through the first lifting hole 1121 without the lifting insert 120, facilitating the unfolding of the strip-shaped sling within the first lifting hole 1121 and preventing stress concentration at the contact point between the sling and the first lifting hole 1121. When using a circular lifting rod for lifting via the lifting device 100, the lifting rod can be installed through the second lifting hole 1201 with the lifting insert 120 installed, facilitating full contact between the circular rod and the inner wall of the second lifting hole 1201, avoiding stress concentration points between the rod and the first lifting hole 1121. Of course, the first lifting hole 1121 and the second lifting hole 1201 can also be other shapes. When lifting with slings through the lifting device 100, the slings can also be installed through the second lifting hole 1201 when the lifting insert 120 is loaded. Alternatively, when lifting with a lifting rod through the lifting device 100, the lifting rod can also be installed through the first lifting hole 1121 when the lifting insert 120 is not loaded. This application does not limit the specific use of the first lifting hole and the second lifting hole.

[0051] In this embodiment of the present invention, the hoisting structure includes a hoisting insert 120 with a second hoisting hole 1201. The hoisting insert 120 is configured to be detachably mounted on the hoisting section 112. Since the hoisting insert 120 is mounted on the hoisting section 112, the second hoisting hole 1201 communicates with the first hoisting hole 1121. Therefore, hoisting can be performed using the second hoisting hole 1201 in addition to the first hoisting hole 1121, allowing the hoisting device 100 to be applicable to more hoisting tools and expanding its scope of application.

[0052] In some optional embodiments, the lifting structure includes a variety of lifting inserts 120, each with a different diameter of its second lifting hole 1201. This allows the second lifting hole 1201 to be adapted to a wider range of lifting devices, thereby further expanding the applicability of the lifting device 100. For example, the second lifting hole 1201 can be a circular hole, and the second lifting hole 1201 of each lifting insert 120 can be configured to mount lifting rods of different diameters.

[0053] In some alternative embodiments, the lifting device 100 is configured such that the two mounting sections 111 of the two lifting assemblies 110 connected to the same side of the base 210 are integrated into one structure. By setting the two mounting sections 111 of the two lifting assemblies 110 connected to the same side of the base 210 as an integrated structure, the integrity of the lifting assembly 110 can be enhanced, thereby improving the structural strength of the lifting assembly 110 and reducing the risk of deformation of the lifting assembly 110.

[0054] In some optional embodiments, the lifting segment 112 of each lifting assembly 110 forms an angle with the mounting segment 111, meaning that the lifting segment 112 and the mounting segment 111 of each lifting assembly 110 are not parallel. Exemplarily, the lifting segment 112 of each lifting assembly 110 can be perpendicular to the mounting segment 111, which can be configured to connect to the aforementioned second side. Based on the mounting segment 111 being connected to the second side, and the lifting segment 112 being perpendicular to the second side, the lifting segment 112 extends from the mounting segment 111 in a direction perpendicular to the second side, thereby reducing the cost of moving the first lifting hole 1121 on the lifting segment 112 away from the base 210. By setting an angle between the lifting segment 112 and the mounting segment 111 of each lifting assembly 110, the combination of the lifting segment 112 and the mounting segment 111 can be more flexible and adaptable to the needs of more usage scenarios.
