The first heavy hinges 3 are vertically arranged between the side nets 24 and the back net 23 at intervals in a connected mode, and the side nets 24 and the back net 23 are connected in a rotating mode.

Specifically, a plurality of first heavy hinges 3 are symmetrically arranged at the rear ends of the two side nets 24.

Referring to fig. 3, each first heavy duty hinge 3 includes a first rotating shaft 31, a fixing member 33 disposed on the back net 23, a rotating member 35 disposed on the side net 24, and two reinforcing members 37.

The fixing member 33 has two vertically spaced support plates 331 projecting therefrom and a connecting plate 333 connecting the two support plates 331. Wherein the support 331 is horizontal. The connecting plate 333 extends vertically and is welded to the outer wall of the bar of the back net 23. The rotor 35 has two vertically opposed rotor plates 351 and a connecting plate 353 connecting the two rotor plates 351. The connecting plate 333 is welded to the bars of the side net 24. The two rotating plates 351 extend between the two support plates 331 and are respectively attached to the support plates 331. The supporting plate 331 and the rotating plate 351 are provided with shaft holes in opposite directions, and the first rotating shaft 31 penetrates through the supporting plate 331 and the rotating plate through the shaft holes, so that the rotating plate 351 can rotate relative to the supporting plate 331 around the first rotating shaft 31.

Preferably, the first rotating shafts 31 of the first heavy hinges 3 on the same side of the side net 24 are of an integral structure, that is, the first heavy hinges 3 on the same side share one vertical first rotating shaft 31 for good coaxiality.

One reinforcing member 37 is connected between the two rotating plates 351, and the other reinforcing member 37 is connected between the lower side of the support plate 331 and the rod of the back net 23, thereby improving the structural strength and connection stability of the first heavy hinge 3.

In the present embodiment, the fixed member 33 and the rotating member 35 are each formed by integrally bending a metal plate member, and the support plate 331 and the rotating plate 351 have sufficient strength. In use, the side net is rotatable about the first rotation axis 31 by the rotation plate 351, and the support plate 331 can bear the vertical load transmitted from the first rotation axis 31, thereby ensuring that the side net 24 can bear the weight without deformation. In addition, a plurality of first heavy hinges 3 are connected between the rear end of the top net 22 and the top end of the back net 23 to form a stable rotating connection.

Referring to fig. 4, a plurality of second heavy hinges 4 are vertically spaced between the front nets 25 and the side nets 24 to rotatably connect the side nets 24 and the front nets 25.

Specifically, a plurality of second heavy hinges 4 are symmetrically arranged at the front ends of the two side nets 24.

Each of the second heavy hinges 4 is a double-hinge structure including a second rotating shaft 41, a mounting member 43 provided on the side net 24, and a hinge member 45 provided on the front net 25.

The mounting member 43 includes a mounting sleeve 431 rotatably fitted over the rod member of the side net 24 and two vertically opposed brackets 433 projecting from the outer peripheral wall of the mounting sleeve 431. Correspondingly, two retaining rings for limiting the up-and-down sliding of the mounting sleeve 431 are fixedly arranged on the rod piece along the axial direction. The hinge 45 is an integral bending plate, and includes a vertical plate 451 and hinge plates 453 protruding from upper and lower sides of the vertical plate 451, respectively. The two hinge plates 453 extend between the two support plates 433 and are respectively attached to the support plates 433, through holes are correspondingly formed in the support plates 433 and the hinge plates 453, and the second rotating shaft 41 penetrates through the through holes. In this way, the mounting member 43 can be rotated about the bar of the side net 24, while the hinge member 45 can be rotated about the second rotating shaft 41, so that the front net 25 can perform a 360-degree rotation function through the second heavy hinge 4. Also, the stay 433 can receive the vertical load transmitted from the second rotating shaft 41, thereby ensuring that the front net 25 can bear load without being deformed.

Further, a synchronizing bar 46 is provided. The synchronization rod 46 extends vertically to connect the mounting sleeves 431 of two upper and lower adjacent second heavy hinges 4, respectively, so as to ensure that a synchronization effect is achieved when the two second heavy hinges 4 are turned over.

Referring to fig. 5, the underframe 1 is used for carrying the total weight of the whole frame 2 and cargo. A plurality of rotating wheels 16 for walking are arranged below the underframe 1.

The base frame 1 includes a frame body 10, a supporting portion 13 provided on the frame body 10, and two corner posts 15 respectively provided at opposite ends of the frame body 10.

Referring to fig. 6, the frame 10 includes a front end beam 101 and side beams 102 bent and extended from both ends of the front end beam 101. The side members 102 are relatively distant from each other in the front-to-rear direction, so that the front end member 101 and the side members 102 enclose a housing chamber 103 having a rear opening. The diameter of the accommodating cavity 103 gradually increases from front to back. The accommodating cavity 103 is used for the chassis 1 of another cage car 100 to enter from the rear opening. When a plurality of cage cars 100 need to be stacked and transported, the bottom net 21 is turned right angle to the front of the back net 23, then the two side nets 24 and the two front nets 25 are turned inwards and placed in front of the bottom net 21, then the narrow opening end of the underframe 1 of one cage car 100 corresponds to the wide opening end of the underframe 1 of the other cage car 100, and the cage cars 100 can be sequentially stacked and arranged together by repeating the steps, so that the storage space is saved, and the transportation is convenient.

The support portion 13 includes two support plates 131 oppositely disposed at the front end of the frame body 10, two parallel cross bars 133, and two limit bars 134. The two support plates 131 are respectively arranged on the left and right sides of the frame body 10 in a turnable manner, and can be rotated to the outer side of the frame body 10 to be unfolded; the overturning design of the supporting plate 131 can facilitate the supporting plate 131 to rotate inwards to be folded inside the frame body 10 when the cage car 100 is transported, and the supporting plate 131 cannot interfere with the frame bodies 10 of other cage cars 100. One end of the support plate 131 is provided with a bent and raised flange 132, and the flange 132 is used for abutting and limiting the bottom net 21 and the side net 24 and preventing the bottom net 21 and the side net 24 from sliding out of the support plate 131. Each cross bar 133 is arranged at the left side and the right side of the frame body 10, and two sets of spaced shaft holes are oppositely arranged on the two cross bars 133; one end of each support plate 131 is provided with a hinge shaft, the hinge shaft is rotatably inserted into the same set of shaft holes, and the support plate 131 can be supported by the frame body 10 when being unfolded outwards around the hinge shaft. Two position-limiting rods 134 are arranged in the gap between the two hinge shafts at intervals, the position-limiting rods 134 are connected with the two cross rods 133, and the support plate 131 is lapped on the position-limiting rods 134 when rotating inwards. In this way, the support plate 131 can transmit the gravity applied by the bottom net 21 and the side net 24 to the frame body 10 below, and prevent the deformation of the bottom net 21 due to an excessive force.

The corner upright posts 15 are arranged at the rear end of the frame body 10 and are used for being connected and fixed with the bottom of the back net 23. The corner upright post 15 comprises a vertical plate 151 vertically protruded on the frame body 10 and wing plates 152 bent and extending from two sides of the vertical plate 151; the two wings 152 are oppositely provided with fixing holes. The vertical plate 151 is provided with a through hole for rotatably connecting a rod piece at the rear end of the bottom net 21.

Referring back to fig. 2, the back net 23 has two side flaps 231 respectively extending forward and bending.

The wing 231 can be accommodated between the wing plates 152 and fixed to the wing plates 152 by bolts. The fixing member 33 is provided at the front end of the side flap 231, that is, the side flap 231 is hinged to the side net 24 by the first heavy hinge 3. The two side wings 231 and the back net 23 enclose a storage space behind the bottom frame 1. The bottom net 21 can be turned backward with respect to the corner posts 15 to stand upright in the storage space. Meanwhile, the side net 24 can be turned inward to enter the storage space when folded, so that it cannot be folded without interference with the bottom net 21.

In the related art, the goods that the cage car transported are more miscellaneous, can set up the intermediate layer board according to the demand. Staff often find that the middle layer plate is needed after half of the goods are loaded, and then the middle layer plate can be installed only by detaching the goods loaded before, so that the loading efficiency is influenced.

Referring to fig. 7 and 8 together, in order to solve the above problem, the cage 100 of the present embodiment is further provided with a novel object carrier 5 that can be drawn out at any time in the cargo state.

The carrier 5 is provided at an intermediate position inside the frame 2, and vertically divides a space inside the frame 2.

Two insertion plates 26 used for connecting the luggage carrier 5 are oppositely arranged in the middle parts of the two side wings 231 of the back net 23, each insertion plate 26 is provided with a groove 202 extending along the vertical direction and a clamping groove 201 communicated with the upper end of the groove 202, and the clamping groove 201 is communicated with the groove 202 to form a through groove in an L-shaped structure.

The rack 5 comprises a rack body 51, a plurality of bolts 52 distributed on the periphery of the rack body 51, and a handle 53 arranged at the front end of the rack body 51. In use, the latches 52 at the front end of the carrier rack 5 are respectively telescopically extended and engaged with the ribs of the two side nets 24. The bolts 52 at the rear end are inserted into the slots 201 to make the carrier 5 horizontal, so that the carrier 5 can carry upper cargo. When the luggage carrier 5 is transported or does not need to be used, a worker can hold the handle 53 to lift upwards, and the bolt 52 slides downwards along the groove 202, so that the whole luggage carrier 5 can be turned downwards relative to the back net 23 and erected in the storage space, and the transportation requirements of different goods are met.

Referring to fig. 9 to 11, the cage 100 further includes two top supporting structures 6 respectively disposed on the top of the two side nets 24.

Each top support structure 6 has a support 61 protruding out, and the support 61 can support the top net 22 upwards, so as to improve the bearing strength of the top net 22, and a part of goods can be placed on the top net 22, thereby improving the transportation efficiency of the goods.

The top support structure 6 comprises a support 61, a rotation member 62 connected to the support 61, two stop blocks and two fixing sleeves 64.

Specifically, the rotating member 62 is a sleeve structure, and the mounting sleeve 431 is rotatably sleeved on the rod member at the top of the side net 24 to drive the supporting member 61 to rotate towards the inside or the outside of the frame 2. The supporting member 61 is a rectangular hollow structure formed by bending a rod member, and has two connecting ends 611 with the outer peripheral wall of the rotating member 62. The supporting member 61 can rotate toward the inside of the frame 2 through the rotating member 62 to support the top net 22 upward and fold on the outside of the side net 24 after being turned to the outside by 270 degrees, thereby reducing the occupied space. The two limit blocks are fixed on the same rod of the side net 24 at intervals through a fixed sleeve 64 and are respectively positioned at two sides of the rotating member 62. The limiting block is in a protruding shape. The two limit blocks can be respectively abutted against the two connecting ends 611 of the support 61 when the support 61 rotates inwards to support the top net 22, so that the support 61 is prevented from rotating downwards under the gravity of the top net 22, and the support 61 is kept in a nearly horizontal supporting state.

Referring to fig. 12 to 14, the cage 100 further includes two rotation handles 7 for preventing the cage from expanding.

The two rotary handles 7 are provided on the left and right sides of the top net 22. The rotary handle 7 is rotatably arranged below the top net 22, and after the rotary handle is transversely arranged, the top net 22 can be prevented from being jacked up by express loaded inside the frame 2.

Each of the rotary handles 7 includes a handle body 71, an elastic member 72 provided at an upper end of the handle body 71, and a fixing nut 73. The fixing nut 73 is provided on the top net 22, and has a groove 701 opening downward. The handle body 71 is telescopically provided below the top net 22 by an elastic member 72. In this embodiment, the elastic member 72 is a compression spring. The handle body 71 has protrusions 711 protruding upward at both ends thereof. When the handle body 71 is placed transversely (i.e. perpendicular to the side net 24), one of the protrusions 711 is used for extending into the groove 701, and the other protrusion 711 is used for abutting against the outer side of the rod of the side net 24 for tightly locking the top net 22 on the top of the side net 24. When the handle body 71 is pulled down and the handle body 71 is rotated by 90 degrees, the locked state of the handle 53 is released, and the handle body 71 is spaced parallel to the side net 24. Thus, the rotating handle 7 can avoid the situation that the top net 22 is not flat due to excessive loading or the cage 100 can not enter the carriage of the transport vehicle as a whole due to the protrusion of the box-expanding top net 22.

In summary, the cage car 100 provided by the invention at least has the following advantages and positive effects:

first, the base frame 1 is provided with a support plate 131, and the support plate 131 can support the bottom net 21 and the side net 24 to improve the bearing performance of the bottom net 21 and ensure that the bottom net 21 is not deformed. Meanwhile, the support plate 131 can transmit the vertical load applied to the side net 24 to the base frame 1, thereby improving the stress state of the side net 24.

Secondly, a plurality of first heavy hinges 3 are respectively connected and arranged between the two ends of the two side nets 24 and the back net 23. Each of the first heavy hinges 3 includes a first rotating shaft 31, a fixed member 33, and a rotating member 35. The fixed member 33 and the rotating member 35 are integrally formed bent metal plates, and the support plate 331 and the rotating plate 351 have sufficient strength. In use, the side net 24 is rotatable about the first rotation axis 31 via the rotation plate 351, and the support plate 331 can bear the vertical load transmitted from the first rotation axis 31, thereby ensuring that the side net 24 can bear the weight without deformation.

Then, a carrier rack 5 which can be drawn out at any time in the loading state is added. The rack 5 comprises a rack body 51, a plurality of bolts 52 distributed on the periphery of the rack body 51, and a handle 53 arranged at the front end of the rack body 51. In use, the latches 52 at the front end of the carrier rack 5 are respectively telescopically extended and engaged with the ribs of the two side nets 24. The bolts 52 at the rear end are inserted into the slots 201 to make the carrier 5 horizontal, so that the carrier 5 can carry upper cargo. When the luggage carrier 5 is transported or does not need to be used, a worker can hold the handle 53 to lift upwards, and the bolt 52 slides downwards along the groove 202, so that the whole luggage carrier 5 can be turned downwards relative to the back net 23 and erected in the storage space, and the transportation requirements of different goods are met.

Finally, a top support structure 6 is provided on each side of the top net 22. The top supporting structure 6 is provided with a support member 61 protruding out, and the support member 61 can upwards support the top net 22, so that the bearing strength of the top net 22 is improved, a part of goods can be placed on the top net 22, and the transportation efficiency of the goods is improved. In addition, the support member 61 can be turned over to occupy no space after being folded and folded, so that the folding of the whole cage 100 is not interfered with each other.
