[0033] An embodiment of the present application provides a side net structure for a cage truck. The side net structure for the cage truck includes a side net main body in a plate-like structure, and a first connecting portion for connecting with the vehicle frame of the cage truck is provided on the side net main body. The side net main body includes opposite first and second sides. A second connecting portion is provided on the first side, and a third connecting portion adapted to the second connecting portion is provided on the second side. The second connecting portion and the third connecting portion are sequentially distributed along the length direction of the top side edge of the side net main body. The following will be described in detail respectively.

[0034] Figure 1 Shown is a schematic structural diagram of an embodiment of the side net structure for a cage truck provided by an embodiment of the present application. As Figure 1 shown, the side net structure 100 for a cage truck includes a side net main body 110 in a plate-like structure, and a first connecting portion 120 for connecting with the vehicle frame of the cage truck is provided on the side net main body 110. By connecting the first connecting portion 120 of the side net structure 100 for a cage truck with the vehicle frame of the cage truck, the side net structure 100 for a cage truck can be installed on the vehicle frame of the cage truck. The specific structure of the first connecting portion 120 will be described in detail below and will not be elaborated here.

[0035] Among them, two side net structures 100 for a cage truck can be partially overlapped. When one side net structure 100 for a cage truck is not applicable to the vehicle frame (not shown in the figure) of a cage truck (not shown in the figure), two or more side net structures 100 for a cage truck can be partially overlapped to increase the overall size of the multiple side net structures 100 for a cage truck, so that the side net structure 100 for a cage truck can be applicable to various different specifications of cage truck structures.

[0036] Optionally, as Figure 1 shown, the side net main body 110 includes opposite first and second sides. A second connecting portion 130 is provided on the first side of the side net main body 110, and a third connecting portion 140 adapted to the second connecting portion 130 is provided on the second side of the side net main body 110. The second connecting portion 130 and the third connecting portion 140 are sequentially distributed along the length direction of the top side of the side net main body 110.

[0037] Thus, as Figure 5, Figure 6 As shown, the second connecting part 130 on the side net body 110 of a cage car side net structure 100 can be connected to the third connecting part 140 on the side net body 110 of another cage car side net structure 100, so that the two cage car side net structures 100 partially overlap in the length direction of the top side of the side net body 110, thereby combining to form a cage car side net structure 100 with a larger size, which not only has high strength but also can be applied to cage cars with larger sizes.

[0038] It should be noted that in the embodiment of the present application, three, four or more cage car side net structures 100 can also be partially overlapped, and the overlapping method can refer to the overlapping method of the above two cage car side net structures 100, which will not be elaborated here.

[0039] In addition, the adaptation of the second connecting part 130 and the third connecting part 140 means that the second connecting part 130 on one cage car side net structure 100 can be connected to the third connecting part 140 on another cage car side net structure 100, and this connection can be a fixed connection or a detachable connection.

[0040] Optionally, as Figure 2 and Figure 4 shown, the second connecting part 130 of the cage car side net structure 100 can include a clamping protrusion, and the third connecting part 140 can include a clamping groove adapted to the clamping protrusion. When the two cage car side net structures 100 are partially overlapped, the clamping protrusion on one cage car side net structure 100 can be inserted into the clamping groove on another cage car side net structure 100, so that the overlapping of the two cage car side net structures 100 is more convenient. When it is necessary to disassemble the two overlapped cage car side net structures 100, only need to make the clamping protrusions on the two cage car side net structures 100 disengage from the clamping grooves.

[0041] Specifically, the clamping protrusion on the cage car side net structure 100 can include a protruding part 131 protruding from the first side surface, and a clamping part 132 connected to one end of the protruding part 131 away from the first side surface, and the clamping part 132 extends out of the opposite sides of the protruding part 131. When the clamping protrusion is inserted into the corresponding clamping groove, the part of the clamping part 132 extending out of the protruding part 131 is hooked with the clamping groove, so that the connection between the two partially overlapped cage car side net structures 100 is more stable. Among them, the clamping groove can penetrate the side net body 110 to facilitate the processing of the clamping groove.

[0042] Of course, the clamping protrusions on one cage truck side net structure 100 and the clamping grooves on another cage truck side net structure 100 can also be clamped together by an interference fit. Alternatively, the second connecting portion 130 on one cage truck side net structure 100 and the third connecting portion 140 on another cage truck side net structure 100 are fixedly connected together by means such as pasting and welding.

[0043] Optionally, as Figure 1 and Figure 3 shown, the number of the second connecting portions 130 can be multiple, and the multiple second connecting portions 130 are sequentially distributed along the length direction of the top side edge of the side net body 110. Thus, when two cage truck side net structures 100 are partially overlapped, one of the second connecting portions 130 on one cage truck side net structure 100 can be selected as needed to be connected to the third connecting portion 140 on another cage truck side net structure 100, so that the two partially overlapped cage truck side net structures 100 have different overall dimensions, thereby further improving the usage range of the cage truck.

[0044] Alternatively, the number of the third connecting portions 140 can also be multiple, and the multiple third connecting portions 140 are sequentially distributed along the length direction of the top side edge of the side net body 110. When two cage truck side net structures 100 are partially overlapped, one of the third connecting portions 140 on one cage truck side net structure 100 can be selected as needed to be connected to the second connecting portion 130 on another cage truck side net structure 100, so that the two partially overlapped cage truck side net structures 100 have different overall dimensions, thereby further improving the usage range of the cage truck side net structure 100.

[0045] It should be noted that the number of one of the second connecting portion 130 and the third connecting portion 140 on the cage truck side net structure 100 can be multiple, or the number of both the second connecting portion 130 and the third connecting portion 140 can be multiple. Of course, the latter can further improve the usage range of the cage truck side net structure 100.

[0046] Optionally, a plurality of second connecting portions 130 and a plurality of third connecting portions 140 are provided on the cage truck side net structure 100, and the plurality of second connecting portions 130 and the plurality of third connecting portions 140 are sequentially distributed along the direction from the top to the bottom of the side net body 110, so as to further improve the connection strength when two cage truck side net structures 100 are partially overlapped.

[0047] Specifically, as Figure 1 and Figure 3As shown, four second connection parts 130 and four third connection parts 140 are provided on the side net body 110 of the cage truck side net structure 100. Two of the second connection parts 130 and two of the third connection parts 140 are close to the top of the side net body 110 and are distributed in sequence along the length direction of the side edge at the top of the side net body 110. The other two second connection parts 130 and two of the third connection parts 140 are close to the bottom of the side net body 110 and are distributed in sequence along the length direction of the side edge at the bottom of the side net body 110.

[0048] Optionally, the first connection part 120 on the cage truck side net structure 100 can be used for detachably connecting with the vehicle frame of the cage truck. Thus, when the vehicle frame of the cage truck is damaged or the cage truck is not applicable, the cage truck side net structure 100 can be detached from the vehicle frame of the cage truck for recycling. In addition, when the cage truck side net structure 100 is damaged, it can also be conveniently detached from the vehicle frame for repair or replacement.

[0049] As Figure 1 and Figure 2 shown, the first connection part 120 can include a first sub-connection part 121 connected to the side edge of the side net body 110, and a second sub-connection part 122 rotatably connected to one end of the first sub-connection part 121 away from the side net body 110. The rotation axis of the second sub-connection part 122 is consistent with the extension direction of the corresponding side edge of the side net body 110, and a connection structure for detachably connecting with the first sub-connection part 121 is provided on the second sub-connection part 122.

[0050] When installing the cage truck side net structure 100 onto the vehicle frame of the cage truck, the second sub-connection part 122 of the cage truck side net structure 100 can be rotated so that the first sub-connection part 121 and the second sub-connection part 122 of the cage truck side net structure 100 are located on both sides of the connecting rod 200 of the vehicle frame, and the connection structure on the second sub-connection part 122 is connected to the first sub-connection part 121 to detachably connect the first connection part 120 with the connecting rod 200 of the vehicle frame.

[0051] Among them, a first clamping part 1211 can be provided on the first sub-connection part 121, and a second sub-clamping part for clamping with the first clamping part 1211 is provided on the second sub-connection part 122. After the first sub-connection part 121 and the second sub-connection part 122 of the cage truck side net structure 100 are located on both sides of the connecting rod 200 of the vehicle frame, the first clamping part 1211 on the first sub-connection part 121 can be clamped with the second clamping part 1221 on the second sub-connection part 122 to detachably connect the first connection part 120 of the cage truck side net structure 100 with the connecting rod 200 of the vehicle frame.

[0052] Optionally, the first clamping portion 1211 on the first sub-connection portion 121 is located at one end of the first sub-connection portion 121 away from the second sub-connection portion 122, and the second clamping portion 1221 on the second sub-connection portion 122 is located at one end of the second sub-connection portion 122 away from the first sub-connection portion 121. When the first sub-connection portion 121 and the second sub-connection portion 122 of the cage side net structure 100 are located on both sides of the connecting rod 200 of the vehicle frame, the second sub-connection portion 122 is clamped to the first clamping portion 1211 of the first sub-connection portion 121 through the second clamping portion 1221, so that the first sub-connection portion 121 and the second sub-connection portion 122 can clamp the connecting rod 200 more stably.

[0053] Specifically, the first clamping portion 1211 is a hook, and the second clamping portion 1221 is a hole. By inserting the hook into the hole and hooking the hook with the hole, the first sub-connection portion 121 and the second sub-connection portion 122 are clamped together. Of course, it is also possible that the first clamping portion 1211 is also a hook, and the second clamping portion 1221 can be a hole, which can also make the first sub-connection portion 121 and the second sub-connection portion 122 clamped together.

[0054] Optionally, after the first sub-connection portion 121 is clamped to the first clamping portion 1211 of the first sub-connection portion 121 through the second clamping portion 1221, a positioning hole can be formed between the first sub-connection portion 121 and the second sub-connection portion 122. The shape of the positioning hole is a through hole adapted to the cross-sectional shape of the connecting rod 200, so that the connection between the first connection portion 120 and the connecting rod 200 is more stable.

[0055] Specifically, as Figure 2 shown, the first sub-connection portion 121 can include a first connection section 1212 and a second connection section 1213 that are sequentially distributed along the direction away from the side net main body 110, and the second sub-connection portion 122 can include a third connection section 1222 and a fourth connection section 1223 that are sequentially distributed along the direction away from the first sub-connection portion 121. The first connection section 1212 and the fourth connection section 1223 extend in a straight line direction, and the second connection section 1213 and the third connection section 1222 are arc structures. When the first sub-connection portion 121 is clamped to the first clamping portion 1211 of the first sub-connection portion 121 through the second clamping portion 1221, there is a gap and they are parallel to each other between the first connection section 1212 and the fourth connection section 1223, and the second connection section 1213 and the third connection section 1222 form a circular hole in a straight line.

[0056] Thus, the first connecting portion 120 can be adapted to connecting rods 200 of different shapes. When the cross-section of the connecting rod 200 is circular, the connecting rod 200 can pass through the circular hole formed between the second connecting section 1213 and the third connecting section 1222. When the cross-section of the connecting rod 200 is rectangular, the connecting rod 200 can pass through the gap between the first connecting section 1212 and the fourth connecting section 1223.

[0057] Optionally, as Figure 1 , Figure 3 and Figure 6 shown, first connecting portions 120 can be provided on both side edges of the top and bottom of the side net body 110, so that the connection between the cage car side net structure 100 and the car frame of the cage car is more stable.

[0058] Among them, a plurality of first connecting portions 120 can be provided on the side edge of the top of the side net body 110, and the plurality of first connecting portions 120 on the side edge of the top of the side net body 110 are distributed in sequence along the extending direction of the side edge of the top of the side net body 110, so that the connection between the top of the cage car side net structure 100 and the corresponding connecting rod 200 is more stable.

[0059] Similarly, a plurality of first connecting portions 120 can also be provided on the side edge of the bottom of the side net body 110, and the plurality of first connecting portions 120 on the side edge of the bottom of the side net body 110 are distributed in sequence along the extending direction of the side edge of the bottom of the side net body 110, so that the connection between the bottom of the cage car side net structure 100 and the corresponding connecting rod 200 is more stable.

[0060] Optionally, the side net body 110, the first connecting portion 120, the second connecting portion 130 and the third connecting portion 140 of the cage car side net structure 100 can be integrally formed, so that the cage car side net structure 100 has higher strength and is more convenient to process.

[0061] Among them, the cage car side net structure 100 can be made of a mixture of polypropylene, polyethylene and glass fiber reinforced resin, so that the cage car side net structure 100 can meet the use temperature range of -40°C to 90°C, and the material processing cost is relatively low.

[0062] As Figure 1 and Figure 3 shown, the side net body 110 can be in a mesh structure to reduce the weight of the side net body 110. Specifically, the side net body 110 can include a plurality of parallel first cross bars 111 and a plurality of parallel second cross bars 112, and the plurality of first cross bars 111 and the plurality of second cross bars 112 intersect with each other to form the side net body 110 in a mesh structure.

[0063] Among the multiple through holes formed by the intersection of multiple first cross bars 111 and multiple second cross bars 112, support plates 113 are also filled at the through holes corresponding to the second connecting portion 130 and the third connecting portion 140, and the second connecting portion 130 and the third connecting portion 140 are respectively arranged on the corresponding support plates 113.

Since this cage cart adopts all the technical solutions of all the embodiments of the above cage cart side net structure, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.
