[0051] ​​In the following description, numerous specific details are set forth to provide a more thorough understanding of the present application. However, it will be apparent to one of skill in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present application.

[0052] Preferred embodiments of the present application will be described herein below with reference to the drawings. It should be noted that the terms "upper", "lower", and similar expressions used herein are for the purpose of illustration only and are not limiting.

[0053] In this document, ordinal numbers such as "first" and "second" cited in the present application are merely identifiers and have no other meaning, such as a specific order, etc.

[0054] For a more complete understanding of the present application, reference is made to the following description taken in conjunction with the accompanying drawings. It should be apparent to those skilled in the art that the following description is illustrative only and not in a limiting sense as numerous modifications and variations within the scope of the present application can be readily developed from this disclosure.

[0055] The present application provides a frame box. The frame box is provided with a support beam 140 and a cushion block 150 at the side portion, which can reduce the degree of downward bending deformation of the bottom side beam 111. In addition, when the frame box is transported, the cushion block 150 can be removed to avoid the bottom side beam 111 bending so that the cushion block 150 moves to the lower side of the bottom corner piece 162.

[0056] Please refer to Figures 1 to 6 The frame box includes a bottom frame 110, a stand column 120 and a top frame 130. The bottom frame 110 includes a bottom end beam and a bottom side beam 111. The bottom end beam and the bottom side beam 111 are connected to form a rectangular frame. The bottom side beam 111 is located at the side portion of the bottom frame 110. The bottom end beam is located at the end portion of the bottom frame 110. The top frame 130 includes a top end beam and a top side beam 131. The top end beam and the top side beam 131 are connected to form a rectangular frame. The top side beam 131 is located at the side portion of the top frame 130. The top end beam is located at the end portion of the top frame 130. The length direction of the stand column 120 is parallel to the vertical direction. The top end of the stand column 120 is connected to the top frame 130. The bottom end of the stand column 120 is connected to the bottom frame 110. In this way, the bottom frame 110, the stand column 120 and the top frame 130 form a substantially cuboid structure. The corner portion of the bottom frame 110 is provided with a bottom corner piece 162.

[0057] As Figure 1As shown, the frame box further comprises a support beam 140. The support beam 140 is located at the side of the frame box. The top end of the support beam 140 is detachably connected to the top side beam 131. The bottom end of the support beam 140 is detachably connected to the bottom side beam 111. The support beam 140 is spaced apart from the upright column 120. Thus, the strength of the frame box is large. In addition, the arrangement of the support beam 140 can disperse the stress of the bottom side beam 111, thereby reducing the degree of downward bending of the bottom side beam 111.

[0058] The support beam 140 is detachably arranged. In this way, during transportation of the frame box, a plurality of frame boxes are stacked. At this time, the support beam 140 is connected to the top side beam 131 and the bottom side beam 111. In this way, the strength of the side of the frame box is increased, and the degree of downward bending of the bottom side beam 111 is reduced, so that the frame box meets the requirements of the sea transportation standard and avoids crushing the frame box below.

[0059] After the frame box is transported to the destination, the frame box can be integrated with equipment. At this time, the support beam 140 can be detached to facilitate heat dissipation, maintenance, detection, etc. of the equipment integrated in the frame box.

[0060] As shown, Figures 1 to 3 The frame box further comprises a cushion block 150. The cushion block 150 is detachably connected to the bottom side beam 111. Part of the cushion block 150 is located below the bottom side beam 111. The cushion block 150 is attached to the lower surface of the bottom side beam 111. In this way, when the bottom side beam 111 is deformed by bending downward, the cushion block 150 can support the bottom side beam 111, thereby reducing the degree of downward bending of the bottom side beam 111.

[0061] The detachable connection of the cushion block 150 to the bottom side beam 111 allows the cushion block 150 to be detached during transportation of the frame box. In this way, the lower surface of the cushion block 150 can be prevented from moving below the bottom corner piece 162 when the bottom side beam 111 bends downward, and the minimum distance between the lower surface of the cushion block 150 and the bottom corner piece 162 is greater than the standard value specified in the sea transportation standard, so that the frame box meets the requirements of the sea transportation standard.

[0062] After the frame box is transported to the destination, the frame box needs to be fixedly arranged at the destination. At this time, the cushion block 150 is connected to the bottom side beam 111 to support the bottom side beam 111, thereby reducing the degree of downward bending of the bottom side beam 111. The cushion block 150 can be fixedly connected to a platform (such as the ground) on which the container is placed.

[0063] In this embodiment, the side of the frame box is detachably provided with a support beam 140. During the transportation of the frame box, the support beam 140 is connected to the top side beam 131 and the bottom side beam 111, which increases the strength of the side of the frame box, reduces the degree of downward bending of the bottom side beam 111, and makes the frame box meet the requirements of the sea transportation standard. After the frame box is transported to the destination, the frame box can be integrated with the equipment. At this time, the support beam 140 can be detached to facilitate heat dissipation, maintenance, detection, and other work of the equipment integrated in the frame box. The bottom side beam 111 is provided with a pad 150. During the transportation of the frame box, the pad 150 can be detached, which can avoid the lower surface of the pad 150 moving below the bottom corner piece 162 when the bottom side beam 111 bends downward, and the minimum distance between the lower surface of the pad 150 and the bottom corner piece 162 is greater than the standard value specified by the sea transportation standard, so that the frame box meets the requirements of the sea transportation standard. After the frame box is transported to the destination, the frame box needs to be fixedly arranged at the destination, and the pad 150 is connected to the bottom side beam 111 to support the bottom side beam 111, thereby reducing the degree of downward bending of the bottom side beam 111.

[0064] Optionally, as shown in Figure 2 and Figure 3 , the pad 150 includes a vertical wall 151 and a horizontal wall 152. The vertical wall 151 and the horizontal wall 152 are both flat plates. The vertical wall 151 is perpendicular to the horizontal wall 152. The vertical wall 151 is located above the horizontal wall 152. The vertical wall 151 is connected to the horizontal wall 152. The vertical wall 151 is detachably connected to the bottom side beam 111. The horizontal wall 152 is located below the bottom side beam 111. The horizontal wall 152 is attached to the lower surface of the bottom side beam 111. Thus, the structure of the pad 150 is simple.

[0065] Further, the bottom frame 110 further includes a first connecting plate 170. The first connecting plate 170 is a flat plate. The bottom side beam 111 includes an upper wing plate 112, a lower wing plate 113, and a web plate 114. The upper wing plate 112 and the lower wing plate 113 are parallel and spaced apart. The web plate 114 is located between the upper wing plate 112 and the lower wing plate 113. The top end of the web plate 114 is connected to the upper wing plate 112. The lower end of the web plate 114 is connected to the lower wing plate 113.

[0066] The first connecting plate 170 is located between the upper wing plate 112 and the lower wing plate 113. The upper end of the first connecting plate 170 is connected to the upper wing plate 112. The lower end of the first connecting plate 170 is connected to the lower wing plate 113. The first connecting plate 170 is located on the outer side of the web plate 114 away from the center of the bottom frame 110. There is a gap between the first connecting plate 170 and the web plate 114. The first connecting plate 170 is parallel to the web plate 114. The first connecting plate 170 does not protrude from the outer edge of the upper wing plate 112 away from the center of the bottom frame 110.

[0067] The first connecting plate 170 is provided with a first mounting hole. The vertical wall 151 is provided with a second mounting hole. The vertical wall 151 is attached to the outer side of the first connecting plate 170 away from the center of the chassis 110. The frame box further comprises fasteners (e.g. bolts and nuts). The fasteners are threaded through the first mounting hole and the second mounting hole to detachably connect the vertical wall 151 to the first connecting plate 170. In this way, the connection of the cushion block 150 and the bottom side beam 111 is facilitated.

[0068] Alternatively, please return to Figure 1 , the length direction of one part of the support beam 140 is inclined to the vertical direction. The length direction of another part of the support beam 140 is parallel to the vertical direction. In this way, the strength of the box body can be further increased, and the degree of downward bending of the bottom side beam 111 can be reduced.

[0069] Alternatively, please refer to Figure 1 , Figures 4 to 6 , both ends of the support beam 140 have a second connecting plate 180. The frame box further comprises a connecting fastener 190. The connecting fastener 190 can be a bolt. The second connecting plate 180 is parallel to the horizontal direction. A first second connecting plate 180 is located below the lower surface of the top side beam 131. Part of the connecting fastener 190 is threaded through the top side beam 131 and the first second connecting plate 180, so that the top end of the support beam 140 is connected to the top side beam 131 through the first second connecting plate 180. A second second connecting plate 180 is located above the upper surface of the bottom side beam 111. Part of the connecting fastener 190 is threaded through the bottom side beam 111 and the second second connecting plate 180, so that the bottom end of the support beam 140 is connected to the bottom side beam 111 through the second second connecting plate 180. In this way, the support beam 140 is facilitated to be assembled and disassembled.

[0070] Further, as shown in Figures 4 to 6 , the second connecting plate 180 has a mounting hole 181 and a positioning hole 184. The axial direction of the mounting hole 181 is parallel to the height direction of the chassis 110. The axial direction of the positioning hole 184 intersects with the axial direction of the mounting hole 181. For example, the axial direction of the positioning hole 184 is parallel to the horizontal direction. The mounting hole 181 comprises a first hole section 182 and a second hole section 183 in communication. The hole diameter of the second hole section 183 is larger than the hole diameter of the first hole section 182. The positioning hole 184 communicates with the second hole section 183.

[0071] The connecting fastener 190 comprises a head 191 and a rod portion 192. The rod portion 192 has an external thread. The outer diameter size of the head 191 is larger than the outer diameter size of the rod portion 192. The rod portion 192 is threaded through the first hole section 182. The head 191 is located in the second hole section 183. The outer peripheral surface of the head 191 has a flat surface.

[0072] The frame box includes a positioning member 160. Positioning member 160 can be a bolt. The end of the rod of positioning member 160, away from the head, serves as an abutment end. The rod of positioning member 160 is inserted into positioning hole 184. The abutment end passes through positioning hole 184 and extends into second hole section 183, located to the side of the plane. This abutment end blocks the plane, thereby preventing the connection fastener 190 from rotating and preventing the connection fastener 190 from leaving the second connecting plate 180.

[0073] Optionally, there are at least two positioning holes 184. The axial directions of some positioning holes 184 are parallel to the length direction of the base frame 110. The axial directions of some positioning holes 184 are parallel to the width direction of the base frame 110. This facilitates the processing of the positioning holes 184.

[0074] Furthermore, if Figure 5 and Figure 6 As shown, the plane includes a first plane 193 and a second plane 194 that are parallel and spaced apart. The outer peripheral surface of the head 191 also includes a connecting surface. The connecting surface can be an arcuate surface 195. The arcuate surface 195 has a first connecting end 196 and a second connecting end 197 that face each other. The first connecting end 196 is connected to the first plane 193. The second connecting end 197 is connected to the second plane 194. The angle α between the line connecting the projection of the first connecting end 196 on the projection plane and the center of the projection of the head 191 on the projection plane, and the line connecting the projection of the second connecting end 197 on the projection plane and the center of the projection of the head 191 on the projection plane.

[0075] It can be understood that in an embodiment not shown, the connecting surface may also be a plane.

[0076] The positioning hole 184 and the mounting hole 181 are communicated through the communication port 185. At least two positioning holes 184 are circumferentially spaced around the axis of the mounting hole 181. There are at least two communication ports 185. The at least two communication ports 185 and the at least two positioning holes 184 are one-to-one corresponding. The positioning hole 184 communicates the mounting hole 181 through the corresponding communication port 185. The at least two communication ports 185 are circumferentially spaced around the axis of the mounting hole 181. In the circumferential direction around the axis of the mounting hole 181, the included angle between the center of the projection of the adjacent two communication ports 185 on the projection plane and the center of the projection of the inner wall surface of the mounting hole 181 on the projection plane is β. Specifically, in the circumferential direction around the axis of the mounting hole 181, the adjacent two communication ports 185 include a first communication port and a second communication port. The line between the center of the projection of the first communication port on the projection plane and the center of the projection of the inner wall surface of the mounting hole 181 on the projection plane is a first line. The line between the center of the projection of the second communication port on the projection plane and the center of the projection of the inner wall surface of the mounting hole 181 on the projection plane is a second line. The included angle between the first line and the second line is β. The projection plane is perpendicular to the axial direction of the mounting hole 181. β>α. Thus, when part of the communication port 185 is blocked by the arc surface 195, the other communication ports 185 are directed towards the first plane 193 or the second plane 194, so that the positioning member 160 and the locking member 161 described below can be arranged, facilitating installation.

[0077] As shown in Figure 5 and Figure 6 , the abutting end of the positioning member 160 has a radial through hole. The frame box further comprises a locking member 161. The locking member 161 can be a split pin. The locking member 161 is arranged in the radial through hole. Thus, the positioning member 160 can be locked in the positioning hole 184, preventing the positioning member 160 from leaving the positioning hole 184.

[0078] Please refer to Figure 3 , the transverse wall 152 of the cushion block 150 has a platform hole 153. The platform hole 153 is located on the outer side of the vertical wall 151 away from the center of the chassis 110. After the frame box reaches the destination, the frame box can be placed on the platform. The fastener can pass through the platform hole 153 to be connected to the platform, thereby fixing the frame box to the platform.

[0079] As shown in Figure 1 , when the cushion block 150 is connected to the bottom side beam 111, the lower surface of the transverse wall 152 is not lower than the position of the lower surface of the bottom corner piece 162. Thus, the structure of the platform is simple.
