[0055] Example 1:

[0056] This embodiment provides a cage car, such as Figures 1 to 17 As shown, it includes: a bottom frame 1, a rear frame 2, a left frame 4, a front frame 3 and a right frame 5;

[0057] The bottom frame 1 is used to carry goods;

[0058] The adjacent two of the rear frame 2, the left frame 4, the front frame 3 and the right frame 5 are rotatably connected in sequence, and the right frame 5 is rotatably connected to the rear frame 2 to enclose and form a cargo space of the cage truck;

[0059] like Figure 11 As shown, one or more of the bottom frame 1, rear frame 2, left frame 4, front frame 3 and right frame 5 is provided with an isolation layer 9 on one side located in the cargo space of the cage vehicle; the isolation layers on the inner sides of the bottom frame 1, rear frame 2, left frame 4, front frame 3 and right frame 5 are detachably connected to form a sealed inner cavity with an upper end opening;

[0060] At least one of the rear frame 2, the left frame 4, the front frame 3 and the right frame 5 is connected to the bottom frame 1;

[0061] Both the left frame 4 and the right frame 5 include at least two sub-plates; the two adjacent sub-plates are rotatably connected, so that when the front frame 3 approaches or moves away from the rear frame 2, it drives the folding and unfolding of multiple sub-plates to realize the folding and unfolding of the cage car; the good foldability can save the storage space of the cage car when the cage car is not in use for storage; and in the process of unfolding and folding, only one of the movable frames, the rear frame 2 and the front frame 3, needs to be pulled to realize the folding or unfolding of the cage car, which is suitable for use on the front line of logistics and improves the experience and efficiency of logistics workers during use.

[0062] An outer flip plate 32 is rotatably connected to the front frame 3 and / or the rear frame 2. A connector for detachably connecting to another adjacent cage car is provided on the movable end of the outer flip plate 32 away from the front frame 3 and / or the rear frame 2. During implementation, the connector can also be used to maintain a closed and locked state between the outer flip plate 32 and the front frame 3 and / or the rear frame 2 on which it is installed.

[0063] In this embodiment, the outward turning plate 32 can be used as a movable door panel of the cage car, or simply as a cargo carrying and / or connecting structure extending outward from the cage car, or it can simultaneously perform the above functions; when used as a movable door panel, it can be turned outward to form a passage for goods to enter and exit the cargo space inside the cage car, and when folded, it forms a relatively closed cargo space inside the cage car, which is convenient for loading and unloading goods; after being turned outward to a relatively parallel position, it can be connected to another adjacent cage car to fix each other, preventing the cage cars inside the car from being relatively displaced and colliding due to road bumps during transportation, thereby ensuring transportation safety. At the same time, after being turned outward to a relatively parallel position, a cargo-carrying platform extending out of the cage car is formed, thereby increasing the cargo capacity of the cage car. In particular, considering that in the actual transportation process, if the cargo is randomly stacked in the car, it will greatly waste space utilization, and excessive stacking is not suitable for some cargo that cannot withstand heavy pressure. The outward turning plate 32 extends outward to form a load-bearing platform, which greatly solves this logistics pain point, avoids excessive pressure on the cargo below, and facilitates the neat stacking of the cargo to greatly improve the utilization rate of the limited car space. It has great positive economic significance and application prospects.

[0064] Further preferably, one of the front frame 3 and the rear frame 2 is rotatably connected to the inner flip plate 22, and the other of the front frame 3 and the rear frame 2 has a bearing member that can support the movable end of the inner flip plate 22 and / or the left frame 4 and the right frame 5 both have bearing members that can support both sides of the inner flip plate 22.

[0065] In this embodiment, the inner flip plate 22 can serve as a supporting structure after the cage car is unfolded, supporting the unfolded cage car and improving the mechanical stability and structural strength of the cage car; at the same time, it also serves as a partition plate and load-bearing platform for the cargo space inside the cage car, especially when there are fewer goods inside the cage car and the goods are multiple small and scattered packages, the partition plate can limit the movement space of the goods during logistics bumps, and prevent the goods from being damaged by violent collisions with each other inside the cage car due to excessive bumps; at the same time, when the goods inside the cage car are fragile packages that cannot withstand heavy pressure, the inner flip plate 22 acts as a load-bearing platform to share the pressure of the goods in the upper space of the cage car, avoiding heavy pressure on the goods in the lower space of the cage car and causing damage.

[0066] Further preferably, a side rotating plate 33 is rotatably connected to one side of the front frame 3 and / or the rear frame 2, and the side rotating plate 33 is rotated to open and close so that the cargo space inside the cage car is connected or separated. In this case, the side rotating plate 33 serves as a movable door of the cage car, which is convenient for loading and unloading cargo. As a first supplement, the side rotating plate 33 can also be hinged to the bottom of the front frame 3 and / or the rear frame 2; as a second supplement, the side rotating plate 33 can also be hinged to the middle of the front frame 3 and / or the rear frame 2, and when opened, it is pulled outward and upward to flip, and when closed, it is released to let the side rotating plate 33 droop naturally; as a third supplement, the side rotating plate 33 can be made of a flexible material, and one side of it can be connected to the front frame 3 and / or the rear frame 2; as a possible extension, the movable end of the side rotating plate 33 away from the front frame 3 and / or the rear frame 2 is provided with a connector to achieve self-closure and locking or connection with another adjacent cage car.

[0067] Example 2:

The fixed bottom plate 11 is fixedly arranged on the bottom frame 1, and the flip bottom plate 12 is rotatably connected to the bottom frame 1 and / or the fixed bottom plate 11; when the cage car is folded, the flip bottom plate 12 is attached to the front side of the front frame 3; when the cage car is unfolded, the flip bottom plate 12 is laid on the bottom frame 1.

[0069] Further preferably, a limiting angle iron 121 is provided on the side of the flip bottom plate 12 near the movable end; when the cage car is folded, the limiting angle iron 121 is located on both sides of the front frame 3 to limit the front frame 3; when the cage car is unfolded, the limiting angle iron 121 is located on both sides of the front frame 3 to limit the front frame 3.

[0070] In an embodiment of replacing the limiting angle iron 121, as Figure 16As shown, it includes a sliding limit bolt 15, which includes a fixing portion 151 and a sliding bolt 152. The fixing portion 151 is fixedly installed on the front frame 3 or the left frame 4 near the front frame 3 or the right frame 5 near the front frame 3. The sliding bolt 152 is slidably connected to the fixing portion 151. A limiting hole for inserting the sliding bolt 152 is provided on the bottom frame 1 or the flip bottom plate 12. The sliding bolt 152 cooperates with the limiting hole to keep the cage car in a stable unfolded state.

[0071] Further preferably, the bottom frame 1 is a trapezoidal frame structure, and the upper bottom end of the trapezoidal structure is located at the front of the bottom frame 1; a reinforcing rod 13 is provided on the inner side of the bottom frame 1.

[0072] Further preferably, casters 14 are provided at the bottom of the bottom frame 1 .

[0073] The rest of this embodiment is the same as that of embodiment 1, so it will not be described again.

[0074] Example 3:

[0075] Example 3 is implemented on the basis of Example 1, as shown in Figure 9 As shown, the bottom frame 1 is a movable bottom plate 7;

[0076] The inner bottom side of one of the rear frame 2 and the front frame 3 is rotatably connected to the movable bottom plate 7, and the other of the rear frame 2 and the front frame 3 and / or both of the left frame 4 and the right frame 5 have an inner step 8 to support the movable bottom plate 7; when the cage car is folded, the movable bottom plate 7 is retracted and abutted against the one of the rear frame 2 and the front frame 3 that is rotatably connected to the movable bottom plate 7; when the cage car is unfolded, the movable bottom plate 7 is unfolded and supported on the inner step 8.

[0077] The rest of this embodiment is the same as that of embodiment 1, so it will not be described again.

[0078] Example 4:

[0079] Example 4 is implemented on the basis of Example 1, as shown in Figure 9 As shown, the bottom frame 1 is a movable bottom plate 7;

[0081] The rest of this embodiment is the same as that of embodiment 1, so it will not be described in detail.

[0082] Example 5:

[0083] Example 5 is implemented on the basis of any one of Examples 1 to 4. In one possible embodiment, it further includes a ceiling 6; the top of the rear frame 2 and the top of the front frame 3 are connected through the ceiling 6; the ceiling 6 includes rigid sheets connected in sequence by rotation / sliding; or the ceiling 6 includes a flexible covering material; the ceiling 6 includes a telescopic frame and a flexible covering material fixed on the telescopic frame.

[0084] The rest of this embodiment is the same as any one of Embodiments 1 to 4, so it will not be repeated here.

[0085] Example 6:

[0086] This embodiment provides a cage car, such as Figures 1 to 8 As shown, it includes: a bottom frame 1, a rear frame 2, a left frame 4, a front frame 3 and a right frame 5;

[0087] The bottom frame 1 is used to carry goods;

[0088] The rear frame 2, the left frame 4, the front frame 3 and the right frame 5 are rotatably connected in sequence, and the right frame 5 is rotatably connected to the rear frame 2 to enclose and form a cargo space of the cage truck;

[0089] Any one of the rear frame 2, the left frame 4, the front frame 3 and the right frame 5 is connected to the bottom frame 1;

[0090] The left frame 4 and the right frame 5 each include two or more sub-panels hinged in sequence; the left frame 4 and the right frame 5 are configured so that when the rear frame 2 and the front frame 3 move closer to or further away from each other, the multiple sub-panels are folded and unfolded, and the left frame 4 and the right frame 5 move closer to or further away from each other simultaneously;

[0091] The front frame 3 includes an outer flip plate 32, which is rotatably connected to the front frame 3. When the outer flip plate 32 is set to flip to a set position, the outer flip plate 32 can form an entrance and exit of the cargo space of the cage car and / or carry cargo and / or be detachably connected to another cage car.

[0092] In this embodiment, the rear frame 2, the left frame 4, the front frame 3 and the right frame 5 are hinged in sequence, and the rear frame 2 and the front frame 3 are arranged at intervals. Under this structure, the left frame 4 and the right frame 5 can be folded to bring the front frame 3 and the rear frame 2 closer together, so that the cage car can be folded when no cargo is loaded to save storage space; or the left frame 4 and the right frame 5 can be stretched to move the front frame 3 and the rear frame 2 away from each other to enclose and form an internal cargo space for the cage car, which is convenient and practical.

[0093] The front frame 3 is rotatably connected to an outer flip plate 32, which can be rotated to be nearly parallel to the bottom frame 1, forming an opening in the upper part of the cargo space inside the cage car for convenient loading and unloading of goods; the outer flip plate 32 can also be used to extend to the outside of the cage car and connect with another cage car to form a cargo platform to increase the cargo loading capacity and play a role in fixing each other; when the truck is not full of cage cars, the connection between the cage cars prevents the cage cars from moving and colliding with each other in the truck box during transportation, which may cause the center of gravity in the truck box to shift, the cage cars to be damaged or tipped over, thereby ensuring the safety of truck driving and cargo transportation; at the same time When there is not enough excess cargo to fill a cage truck, the cargo platform provided by the extended outer flip plate 32 can save a cage truck, especially considering that in the actual transportation process, if the cargo is stacked randomly in the compartment, it will greatly waste space utilization, and excessive stacking is not suitable for some cargo that cannot withstand heavy pressure. The outer flip plate 32 extends outward to form a load-bearing platform, which greatly solves this logistics pain point. It not only avoids excessive pressure on the cargo below, but also facilitates the neat stacking of cargo to greatly improve the utilization rate of limited compartment space, which has a positive effect on the economy of transportation and improving space utilization.

[0094] like Figure 2 As shown in the figure, the two right sub-panels are hinged together to form the right frame 5. Two pin ears 01 are coaxially provided with a pair of pin holes, and a pin 02 extends through the pin holes to achieve a rotational connection between the two pin ears 01. The two pin ears 01 are located on the outer sides of the two right sub-panels, respectively. When the front frame 3 and the rear frame 2 approach each other, the two right sub-panels will abut against each other when rotating outward, preventing further outward rotation. This prevents the right frame 5 from bulging outward during folding, improving the convenience of folding the cage car. At the same time, when the cage car is extended and loaded, it can prevent the right frame 5 from bulging outward, ensuring the stability of the cage car's own structure and the restraint of the cargo inside the cage car. The left frame 4 and the right frame 5 are structurally identical and symmetrical, and the corresponding left and right sub-panels and the connecting structure between them are also identical and symmetrical.

[0095] Further optimized, the movable end of the outer flip plate 32 is provided with a first connecting structure, and the rear frame 2 and / or the front frame 3 and / or the left frame 4 and / or the right frame 5 are provided with a second connecting structure, and the first connecting structure can be detachably connected to the second connecting structure on another cage car.

[0096] like Figure 7 and Figure 8 As shown, the first connecting structure on the outer flip plate 32 is connected to the second connecting structure on another cage car through movement; and it is not limited to which side of the cage car the second connecting structure is located. In actual application, more combinations can be brought about, which is convenient for flexible use according to actual conditions.

[0097] Further optimization, such as Figure 6Also includes a front crossbar 31, a rear crossbar 21, the front crossbar 31 is disposed laterally on the front frame 3, as shown Figure 7 and Figure 8 As shown, the outer flip plate 32 is hinged to the front cross bar 31, and a first connecting structure is provided on the movable end of the outer flip plate 32; the rear cross bar 21 is transversely arranged on the rear frame 2; Figure 6 As shown, a second connection structure is provided on the front cross bar 31 and / or the rear cross bar 21; and the first connection structure can be detachably connected to the second connection structure of another cage vehicle.

[0098] Further optimization, such as Figure 6 and Figure 7 As shown, the cage car further includes an inner flip plate 22 , which is hinged to the rear cross bar 21 . The inner flip plate 22 can be flipped to partition the cargo space of the cage car and / or carry cargo.

[0099] The inner flip plate 22 can be flipped to a state that is nearly parallel to the bottom frame 1, and the movable end of the rear flip plate can be connected to the front cross bar 31 or the inner flip plate 22 is supported by the rear cross bar 21, etc.; it plays the role of partitioning the cargo space inside the cage car, stabilizing the cage car structure and preventing cargo from being crushed; firstly, when the cage car has a small cargo capacity or the cargo is loose, the partition of the inner flip plate 22 can stabilize the items in a smaller space, limit the range of movement of the cargo during bumps, and prevent the cage car from losing its center of gravity and tipping over due to bumpy movement of the cargo, which plays a role in protecting the cargo. The limiting protection function improves transportation reliability; secondly, when the inner flip plate 22 is flipped to the horizontal, its side can support the extended left frame 4 and the right frame 5, and the front and rear ends of the inner flip plate 22 also support the rear frame 2 and the front frame 3 accordingly to prevent the cage car from deforming. Structurally, the internal cargo space of the cage car formed by the rear frame 2, the left frame 4, the front frame 3, and the right frame 5 is stable; finally, when the inner flip plate 22 is flipped to the horizontal, a cargo carrying platform is formed to share part of the downward pressure of the cargo, which can prevent the cargo at the bottom of the cage car from being damaged due to the heavy pressure.

[0100] Further optimization, such as Figure 2 and Figures 6 to 8 , also includes a side turning plate 33, which is hinged to one side of the front frame 3. The side turning plate 33 below the front frame 3 can be opened sideways to form an opening for the lower section of the cargo space inside the cage car to facilitate loading and unloading of goods.

[0101] Further optimization, such as Figures 6 to 8 As shown, it also includes ribs 03 and panels 04; the ribs 03 are respectively arranged on the rear frame 2, the left frame 4, the right frame 5, the outer flip plate 32, the inner flip plate 22, and the side turn plate 33; the panels 04 are fixedly installed on the rear frame 2, the left frame 4, the right frame 5, the outer flip plate 32, the inner flip plate 22, and the side turn plate 33, and / or the panels 04 are connected to the ribs 03.

[0102] The ribs 03 further enhance the structural strength of the rear frame 2, left frame 4, right frame 5, outer flip plate 32, inner flip plate 22, and side turn plate 33. They also support and secure the enclosure 04, preventing it from deforming due to external forces or compression from the cargo within the cage. The enclosure 04 thus restrains and protects the cargo within the cage vehicle.

[0103] Further optimization, such as Figure 1 and Figures 5 to 7 As shown, it also includes a fixed bottom plate 11 and a flip bottom plate 12. The fixed bottom plate 11 is provided at the rear section of the top surface of the bottom frame 1. When the front frame 3 is brought closest to the rear frame 2, the front frame 3, the left frame 4 and the right frame 5 are all located above the fixed bottom plate 11. The flip bottom plate 12 is hinged to the front end of the fixed bottom plate 11. When the front frame 3 is retracted to be closest to the rear frame 2, the flip bottom plate 12 flips upward to abut against the front frame 3.

[0104] When the cage trolley is folded, the flip bottom plate 12 can be flipped upward to fit against the folded front frame 3, further improving the foldability of the cage trolley. In the actual situation of folding the cage trolley for storage, the storage space may be used to stack other items. After flipping the flip bottom plate 12 upward, the bottom frame 1 and the empty part in the middle of the frame are exposed, which can be used more effectively according to the actual situation.

[0105] Further optimization, such as Figure 4 As shown, a limiting angle iron 121 is provided on the front side of the flip base plate 12; the limiting angle iron 121 is configured to contact the left frame 4 and / or the right frame 5 to limit the front frame 3 from being located directly above the flip base plate 12 when the front frame 3 is away from the rear frame 2 to the maximum distance.

[0106] Further optimization, such as Figure 5 As shown, the base frame 1 has a trapezoidal structure, with the upper bottom end of the trapezoidal structure located at the front of the base frame 1. A reinforcement rod 13 is provided at the front of the base frame 1, and casters 14 are provided at the bottom of the base frame 1. The reinforcement rod 13 strengthens the structural strength of the base frame 1 and also provides more support for the tilting base plate 12 when bearing weight, preventing deformation of the front and rear ends of the tilting base plate 12 due to an excessive support span. The casters 14 can be either universal wheels or fixed wheels depending on the actual situation.

[0107] Further optimization also includes a roof 6; the roof 6 is arranged on the open top of the cage car, and the roof 6 and the cage car can be fixedly connected or detachably connected.

[0110] The two ends of the telescopic / folding frame 62 are respectively connected to the front frame 3 and the rear frame 2 , or the two ends of the telescopic frame are respectively connected to the left frame 4 and the right frame 5 .

[0111] The telescopic / folding frame 62 used can be a telescopic rod with multiple telescopic sections that extend and retract in sequence, or it can be a movable structure folding structure similar to an umbrella frame.

[0112] Another optional implementation method, such as Figure 13 and Figure 14 As shown, the roof 6 includes a flexible covering material 61 and a fixing rod 63. The edge of the flexible covering material 61 is connected to the top of the fixing rod 63. The bottom of the fixing rod 63 is provided with a fixing device 631 for connecting to any one of the rear frame 2, left frame 4, front frame 3 and right frame 5. Figure 14 It can be seen that the fixing device 631 is a semi-ring clamp that can be clamped on the outer wall of the circular vertical rod of the rear frame 2, left frame 4, front frame 3 and right frame 5. However, this is not a limitation of the structure. It is only used as a schematic diagram. The structure and type of the fixing device 631 can be diverse to adapt to the specific structure of the rear frame 2, left frame 4, front frame 3 and right frame 5.
