Abstract
Description
[Technical field]
[0001] The present application belongs to the technical field of cargo carts, and in particular relates to a foldable cage cart. [Background technology]
[0002] Existing mesh cages are generally composed of a base, a base mesh, side support meshes and front and rear meshes. The base and the side support meshes and the front and rear meshes are directly pivotally mounted, and there is no limiting device around them. When the cages are stacked in a folded state, they are very prone to accidental collapse, and the safety is relatively poor. In addition, the side support meshes and the front and rear meshes of existing mesh cages are only surrounded by ordinary iron wires. When the cages are stacked in an open state, the pressure is concentrated at the connection between the side support meshes and the base. Due to the small contact area, the pressure generated is relatively large, thereby limiting the bearing capacity of the cage. [Contents of the utility model]

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0027] See also Figures 1 to 8 A foldable cage car includes a base frame 1, four support columns 2 arranged on the base frame 1, a side support frame 3 pivotally installed with the support columns 2 along the length direction of the base frame 1, and a front net support frame 4 and a rear net support frame 5 pivotally installed with the support columns 2 along the width direction of the base frame 1, and the support columns 2 limit the side support frames 3 from flipping outward.
[0028] The foldable cage car of the present application effectively enhances the structural stability and load-bearing capacity of the cage car by introducing a base frame, support columns, and pivotally mounted side support frames and front and rear net support frames. The introduction of the support columns limits the side support frames from flipping outward, thereby avoiding the potential safety hazard of the cage car collapsing when in a folded state. At the same time, by pivotally mounting the front and rear net support frames, the pressure is effectively dispersed, the problem of pressure concentration is reduced, and the load-bearing capacity of the cage car is improved.
[0029] Furthermore, as a preferred implementation of the present solution but not a limitation, the support column 2 is a U-shaped channel steel with an opening facing inward along the length direction of the base frame 1 .
[0030] In this embodiment, the design can effectively increase the connection stability between the support column and the base frame. Through the structural characteristics of the U-shaped channel steel, the support column can be more tightly fixed to the base frame, reducing the possibility of shaking and loosening of the connection part, thereby improving the structural stability of the entire cage car.
[0031] Furthermore, as a preferred embodiment of the present invention but not a limitation, the front mesh support frame 4 and / or the rear mesh support frame 5 include a lower mesh frame 41 pivotally mounted to the support column 2 and an upper mesh frame 42 hinged to the top of the lower mesh frame 41, and the height H of the upper mesh frame 42 and the height h of the lower mesh frame 41 are both smaller than the width D of the base frame 1.
[0032] In this embodiment, it can be configured so that only the front net support frame is divided into an upper net frame and a lower net frame, or only the rear net support frame is divided into an upper net frame and a lower net frame, or both the front and rear net support frames are divided into an upper net frame and a lower net frame, wherein the upper net frame and the lower net frame are connected by hinges, and their heights are both less than the width of the base frame. This design makes the entire net frame structure more flexible. Since the heights of the upper and lower net frames are both less than the width of the base frame, when the cage car is folded, the upper and lower net frames can be staggered and folded, which reduces the space occupied during stacking and improves the stacking efficiency.
[0033] Furthermore, as a preferred implementation mode of the present invention but not a limitation, at least one pin 411 is provided on the side of the lower grid 41, and a clamping block 31 is provided on the side support frame 3. A clamping slot matching the pin 411 is provided on the clamping block 31, and the pin 411 can be clamped in the clamping slot to limit the flipping of the lower grid 41 relative to the base frame 1.
[0034] In this embodiment, the stability and safety of the cage car during use are ensured, and the lower grid frame is prevented from accidentally flipping over when stacking goods, thereby avoiding damage to goods and injury to personnel. At the same time, the matching design of the pin and the slot is simple and effective, easy to operate, and improves the operability and convenience of the cage car.
[0035] Furthermore, as a preferred implementation mode of the present invention but not a limitation, at least one latch 421 is provided on the side of the upper grid 42, and the end of the latch 421 has a downwardly bent limit hook, and a limit block 32 is provided on the side support frame 3, and a lock hole matching the latch 421 is provided on the limit block 32, and the limit hook can be clamped on the inner side wall of the lock hole to limit the rotation of the upper grid 42 relative to the lower grid 41.
[0036] In this embodiment, it is ensured that the upper grid frame will not rotate accidentally during the use of the cage truck, effectively preventing the misalignment of the goods and the unstable stacking, thereby improving the safety and stability of the transportation process. At the same time, the matching design of the latch and the lock hole is simple and effective, easy to operate, so that users can conveniently perform loading and unloading operations.
[0037] Furthermore, as a preferred implementation mode of the present invention but not a limitation thereof, when the folding cage trolley is in the unfolded state, the pin 411 is engaged with the card slot and the latch 421 is engaged with the lock hole to limit the side support frame 3 from flipping inward; when the folding cage trolley is in the folded state, the lower grid 41 flips inward relative to the base frame 1, the upper grid 42 flips outward relative to the lower grid 41, and the side support frame 3 flips inward relative to the base frame 1, and the distance S between the side support frame 3 and the support column 2 and the bottom of the base frame 1 is greater than the thickness B when the upper grid 42 and the lower grid 41 are stacked.
[0038] In this embodiment, when the folding cage trolley is in the unfolded state, the pin is engaged with the slot and the latch is inserted into the lock hole, which limits the inward flipping of the side support frame, and cooperates with the support column to limit the outward flipping of the side support frame, thereby ensuring the structural stability of the cage trolley; in the folded state, the lower grid flips inward, the upper grid flips outward, and the side support frame flips inward, and the distance from the side support frame to the support column hinge to the bottom is greater than the thickness of the upper grid and the lower grid when they are stacked. This design makes the cage trolley more compact when stacked, saves storage space, and improves storage efficiency.
[0039] Furthermore, as a preferred implementation mode of the present invention but not a limitation, a support tube 6 is provided between the two support columns 2 pivotally connected to the side support frame 3 , and the support tube 6 is in contact with the bottom of the side support frame 3 .
[0040] In this embodiment, the provision of the support tube enhances the connection stability between the side support frame and the support column, effectively reducing the possibility of shaking and loosening at the connection, thereby improving the structural stability and safety of the entire cage car. Secondly, the fitting design between the support tube and the bottom of the side support frame makes the side support frame more stable during folding and unfolding, avoiding structural loosening and tilting caused by loose connections, and further ensuring the reliability of the cage car during use. In addition, the addition of the support tube can also effectively disperse the pressure on the side support frame, reduce the load on the connection point, and extend the service life of the cage car.
[0041] Furthermore, as a preferred embodiment of the present invention but not a limitation, four foot posts 7 are provided at the bottom of the base frame 1, and a latch 71 is provided at the bottom of the foot posts 7. When multiple folding cage carts are stacked in an unfolded state or a folded state, the latch 71 can be latched at the top of the corresponding side support frame 3.
[0042] In this embodiment, a foot column is provided at the bottom of the base frame, and a clamping position is designed at the bottom of the foot column, so that when multiple folding cage carts are stacked in an unfolded or folded state, the clamping position can be easily clamped on the top of the corresponding side support frame. At the same time, the establishment of the clamping position also makes the stacking operation of the cage carts simpler and faster, and improves the stacking efficiency. In summary, the solution of providing foot columns and designing clamping positions at the bottom of the base frame provides a stable and reliable connection for the stacking of multiple folding cage carts, enhancing storage efficiency and convenience of operation.
[0043] Furthermore, as a preferred implementation mode of the present invention but not a limitation, four limit members 8 are provided on the top of the side support frame 3. When a plurality of folding cage carts are stacked in an unfolded state, the limit members 8 fit snugly with the foot posts 7 to limit the relative displacement movement of adjacent folding cage carts.
[0044] In this embodiment, the position stability of the folding cage car during the stacking process is ensured, the sliding and misalignment between adjacent cage cars is prevented, and the stacking is effectively kept neat and stable. At the same time, the fitting design of the limiter and the foot column also makes the stacking operation of the cage car easier and faster, and improves the stacking efficiency.
[0045] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the base frame 1 is provided with a limit stopper 9 for limiting the front net support frame 4 and / or the rear net support frame 5 from flipping outward relative to the base frame 1 .
[0046] In this embodiment, the stability of the front and rear net support frames in the unfolded state is ensured, and the structural instability and safety hazards caused by accidental overturning are prevented. The setting of the limit stopper effectively protects the structural integrity and stability of the trolley during use, and improves its reliability and safety.
[0047] The working principle of this embodiment is as follows:
[0048] The foldable cage car of the present application effectively enhances the structural stability and load-bearing capacity of the cage car by introducing a base frame, support columns, and pivotally mounted side support frames and front and rear net support frames.
