As shown in FIG1 , the embodiment of the utility model provides a folding material rack suitable for transporting and packaging axles, comprising a base 1, a plurality of corner columns 2 and two support assemblies 3. The plurality of corner columns 2 are arranged at intervals along the circumference of the base 1 and protrude upward from the base 1. The two support assemblies 3 are respectively arranged on opposite sides of the base 1, and each support assembly 3 is rotatably connected to the corner column 2, so that the support assembly 3 can stand upright on the upper surface of the base 1. At this time, the base 1 and the two support assemblies 3 together form a box structure with a cavity, and the box structure is used to place the axle.

Furthermore, the support assembly 3 can also be rotated inwardly to be folded on the base 1. At this time, the rack can be folded up to reduce the occupied space.

For the convenience of description, the position where the support assembly 3 stands upright on the upper surface of the base 1 is defined as the first position, and the position where the support assembly 3 is rotated inwardly and folded on the base 1 is defined as the second position.

Continuing to refer to Fig. 1, the outer contour of the base 1 is rectangular. Specifically, the base 1 includes two cross beams 11 and two longitudinal beams 12, and the two cross beams 11 and the two longitudinal beams 12 are respectively staggered and connected end to end.

There are four corner columns 2, which are respectively arranged at the four corners of the base 1. Each corner column 2 is connected to the end of a horizontal beam 11 and a longitudinal beam 12 respectively.

Each support assembly 3 may include two connecting columns 31. The two connecting columns 31 of each support assembly 3 are rotatably connected to the corresponding two corner columns 2, so that each support assembly 3 can stand upright relative to the base 1, or each support assembly 3 can be rotated inward to be folded on the base 1.

As shown in FIG2 , the corner column 2 includes two side plates 21 connected at an angle and a baffle 22, and the upper ends of the two side plates 21 and the baffle 22 both extend upwardly beyond the upper surface of the base 1. The two side plates 21 are respectively fitted and fixed to two adjacent outer side surfaces of the base 1, that is, the two side plates 21 are respectively fitted and fixed to the end surfaces of the adjacent cross beam 11 and the end surfaces of the longitudinal beam 12.

The baffle 22 stands upright on the upper surface of the base 1 and is connected and fixed to one side plate 21 and is spaced apart from the other side plate 21. The baffle 22 and the two side plates 21 define a limiting cavity 23 with an opening, and the limiting cavity 23 is used to accommodate the bottom end of the limiting connection column 31.

For the convenience of description, the side plate 21 relatively spaced from the baffle 22 is defined as a first side plate 211 , and the side plate 21 fixedly connected to the baffle 22 is defined as a second side plate 212 .

When the support assembly 3 is in the first position, the bottom end of the connecting column 31 is received in the limiting cavity 23, and the top end thereof protrudes upward from the two side plates 21. When the rack is empty, the connecting column 31 only needs to be pulled vertically upward so that the bottom of the connecting column 31 exceeds the upper surface of the base 1 in the horizontal direction, and then the connecting column 31 is rotated inward, so that the support assembly 3 can be moved to the second position, and the purpose of folding and storing the rack can be achieved.

The connection column 31 and the corner column 2 can be connected in rotation in the following manner: a clamping hole 2111 is provided in the middle of the first side plate 211 of the corner column 2, a connecting hole is provided at the bottom of the connection column 31, and the connection column 31 is hingedly connected to the corner column 2 through an adapted fastener 311 passing through the clamping hole 2111 and the connecting hole. Thus, the connection column 31 and the corner column 2 are connected in rotation, and then the support assembly 3 is rotated inwardly relative to the base 1, and the material rack can be folded.

Through the cooperation of the clamping hole 2111, the connection hole and the fastener 311, the purpose of keeping the connection column 31 in the limiting cavity 23 of the corner column 2 can be achieved when the connection column 31 is lifted upward. Specifically, the clamping hole 2111 is waist-shaped and extends in the vertical direction, and the top of the clamping hole 2111 exceeds the upper surface of the base 1 in the horizontal direction. When the connection column 31 is lifted upward, the fastener 311 moves in the clamping hole 2111 until it abuts against the top of the clamping hole 2111. At this time, the connection column 31 cannot be further lifted upward, so that the connection column 31 is kept in the limiting cavity 23 of the corner column 2. In addition, when the connection column 31 is lifted upward to make the fastener 311 move to the top of the clamping hole 2111, the bottom end of the connection column 31 protrudes from the upper surface of the base 1. At this time, the connection column 31 can be rotated inward to move the support assembly 3 to the second position.

It should be noted that, in other embodiments, in addition to the fastener 311 being inserted into the connection hole formed in the connection column 31 , the fastener 311 may also be directly welded to the connection column 31 .

In one embodiment, a limiting groove 24 is provided at the upper end of the corner column 2, and a limiting block 312 adapted to the limiting groove 24 is provided at the connecting column 31. The limiting block 312 can be inserted into the limiting groove 24 to keep the support assembly 3 in an upright state. Specifically, the limiting groove 24 is provided at the upper end of the first side plate 211 of the corner column 2 and the upper end of the baffle 22. The limiting block 312 is provided on both side surfaces of the connecting column 31. When the support assembly 3 is located at the first position, the limiting block 312 is inserted into the limiting groove 24 to keep the support assembly 3 at the current position. When the support assembly 3 is changed from the first position to the second position, the connecting column 31 needs to be pulled upwards to disengage the limiting block 312 from the limiting groove 24, and then the connecting column 31 can be rotated inwards to move the support assembly 3 to the second position.

By providing the limiting block 312 to cooperate with the limiting groove 24, the support assembly 3 can be stably maintained in an upright state, thereby providing strong support for the subsequently placed vehicle axle.

It should be noted that, in other embodiments, the limit groove 24 may be opened only at the upper end of the baffle 22 or the first side plate 211. In this case, a limit block 312 adapted to the limit groove 24 needs to be set at the corresponding position of the connecting column 31. As long as the support assembly 3 can be located in the first position, the limit block 312 is clamped in the limit groove 24 to maintain the support assembly 3 in an upright state.

In one embodiment, a buckle cup 313 is provided at the top of the connecting column 31, and a foot 25 capable of accommodating the buckle cup 313 is provided at the bottom of the corner column 2. The cross section of the foot 25 is rectangular, and the cross section of the buckle cup 313 is also rectangular, that is, the foot 25 matches the shape of the buckle cup 313. Moreover, the cross-sectional area of the buckle cup 313 is smaller than the cross-sectional area of the foot 25, that is, the size of the foot 25 matches that of the buckle cup 313, so that the foot 25 can accommodate the buckle cup 313.

By providing the foot 25 and the buckle cup 313, the purpose of stacking multiple racks for loading axles can be achieved. Specifically, the foot 25 is a hollow cylindrical structure, and the foot 25 is gradually expanded from top to bottom. The buckle cup 313 includes an abutment ring 3131, which can be accommodated in the foot 25. Under the action of gravity, the abutment ring 3131 and the foot 25 are more tightly fitted, so that the stacked racks are not easy to shake.

When the support assembly 3 is in the second position, multiple racks can also be stacked. Specifically, the top outer dimensions of the corner column 2 are adapted to the foot 25, so that the top of the corner column 2 can also be accommodated in the foot 25. Therefore, through the cooperation between the corner column 2 and the foot 25, multiple folding racks when the support assembly 3 is in the second position can be stacked in the vertical direction, further reducing the area occupied by the warehouse.

As shown in FIG. 1 and FIG. 2 , the two support assemblies 3 are respectively located above the two cross beams 11 of the base 1 to support the ends of the axle. Specifically, the support assembly 3 also includes a connecting beam 32, a support platform 33 and two support frames 34. The connecting beam 32 is connected between the two connecting columns 31. The two support frames 34 are respectively arranged at the two ends of the connecting beam 32, and the two support frames 34 are respectively fixedly connected to the adjacent connecting columns 31, that is, the connecting beam 32 is connected to the connecting column 31 through the support frames 34. The support platform 33 is arranged on the connecting beam 32 and is fixedly connected to the support frame 34.

When the support assembly 3 is in the first position, the support assembly 3 plays the role of supporting the axle. At this time, the support assembly 3 is in an upright state as a whole, and the end of the axle is clamped on the support platform 33. And the connecting beam 32 can abut against the crossbeam 11 of the base 1, so that the support assembly 3 can stably support the axle. When the support assembly 3 is in the second position, the purpose of folding the material rack can be achieved. At this time, the connecting column 31 and the support frame 34 are folded inwardly on the base 1, so that the support assembly 3 can be folded on the base 1.

It can be understood that in the example of the present application, the setting of the support frame 34 can, on the one hand, enhance the structural strength of the support assembly 3, so that the connection beam 32 and the connection column 31 are reliably connected. On the other hand, it can facilitate the setting of the two inclined plates 322 of the support platform 33 and improve the supporting strength of the support platform 33, as described below.

It should be noted that in other embodiments, the support frame 34 may not be provided, or only one support frame 34 may be provided. When the support frame 34 is not provided, the connecting beam 32 is directly connected to the connecting column 31, and the support platform 33 is provided on the upper surface of the connecting beam 32. When only one support frame 34 is provided, the support frame 34 may be connected to one end of the connecting beam 32 and connected to the adjacent connecting column 31, and the support platform 33 is provided on the connecting beam 32 and can be connected to the support frame 34.

Referring to Fig. 3, the support platform 33 is formed with a receiving groove 331 with an opening facing upward, and the receiving groove 331 is gradually expanded in the vertically upward direction. The receiving groove 331 is used to clamp the end of the axle to achieve more stable support of the axle. Specifically, the support platform 33 includes two inclined plates 332, and the two inclined plates 332 are arranged at an angle relative to the vertical direction. The two inclined plates 332 are arranged relative to each other to form the receiving groove 331. Among them, one end of one inclined plate 332 is fixedly connected to the connecting beam 32, and the other end is fixedly connected to a supporting frame 34. One end of the other inclined plate 332 is fixedly connected to the connecting beam 32, and the other end is fixedly connected to the other supporting frame 34. And the two connection points formed by the two inclined plates 332 being respectively connected to the connecting beam 32 can be a certain distance apart.

When the end of the axle is placed on the receiving groove 331, it is equivalent to that the two circumferential sides of the end of the axle are respectively in contact with the two inclined plates 332. Under the action of gravity, the axle can be better clamped in the receiving groove 331 formed by the two inclined plates 332, so that the support platform 33 can better stably support the axle and make it difficult for the axle to move up and down. In addition, because the two ends of the axle are usually cylindrical, the diameters of the ends of the axles of different models are different, so the receiving groove 331 is set in a gradually expanding shape, so that the receiving groove 331 can be used to place axles of different models, with better compatibility and stronger practicality.

Referring to FIG. 3 , one inclined plate 332 forms an angle α with the vertical direction, and the angle α may be 41°; the other inclined plate 332 forms an angle β with the vertical direction, and the angle β may be 54°. In this example, the angle between the two inclined plates 332 is 95°, which can be adapted to support the ends of axles of most sizes. Moreover, the two inclined plates 332 have different inclination angles, which can better adapt to supporting axles whose center of gravity is biased toward one side of the central axis at both ends of the axle. Therefore, the folding rack of the present application can be better suitable for the placement of axles of different models and stably support each axle.

In other embodiments, the two inclined plates 332 may also be arranged at other angles with the vertical direction. Furthermore, the angles formed by the two inclined plates 332 with the vertical direction may be the same.

Preferably, a buffer pad 4 may be provided on each inclined plate 332 , and the buffer pad 4 has a buffering and shock-absorbing effect to better protect the axle.

Referring to Figures 2 and 4, the base 1 is provided with a bearing portion, which is used to support the middle part of the axle. Specifically, the middle part of the axle usually has a protrusion. The bearing portion is used to abut against the protrusion to play a supporting role.

In one embodiment, the bearing part includes a support beam 13, and the two ends of the support beam 13 are respectively connected to the two cross beams 11. When the folding rack is fully opened and the axle is placed on the support assembly 3, the protruding part of the axle is placed on the support beam 13. Since the middle part of the axle of different vehicle models is arranged differently, the support beam 13 and the longitudinal beam 12 of the base 1 may also bear the middle part of the axle at the same time.

Alternatively, in other embodiments, the support beam 13 may not be provided, and the longitudinal beam 12 of the base 1 may serve as a load-bearing portion capable of supporting the middle portion of the axle.

Therefore, the folding rack of the present application has a more flexible and more versatile support method for the middle part of the axle. That is, according to the axle structure of different vehicle models, the middle part of the axle can be supported on the support beam 13 or the longitudinal beam 12, or the middle part of the axle can be supported on the support beam 13 and the longitudinal beam 12 at the same time.

Preferably, the bearing part also includes a positioning block 14, which is arranged in the middle of the support beam 13 to bear the middle of the axle. The positioning block 14 is protrudingly arranged on the upper surface of the support beam 13, and it can have a certain height. Since the middle of the axle of different vehicle models is arranged differently, the positioning block 14 can be arranged to ensure that the bearing part can be against the middle of the axle to better support the axle. For example, when the heights of the structures on both sides of the middle of the axle are different, the high side can be against the positioning block 14, and the low side can be against the longitudinal beam 12. Thereby, the base 1 and the bearing part thereon can better support the middle of the axle and prevent the axle from tipping over due to movement.

Preferably, a buffer pad 4 is provided on the positioning block 14 and in the middle of the longitudinal beam 12 , and the buffer pad 4 has a buffering and shock-absorbing effect to better protect the axle.

It can be understood that when the support assembly 3 moves to the second position, the buffer pad 4 on the longitudinal beam 12 also has the function of blocking the direct collision between the connecting column 31 and the longitudinal beam 12, thereby effectively extending the service life of the material rack.

As shown in FIG. 2 , a notch 3321 is provided on an inclined plate 332 of the support assembly 3. When the support assembly 3 is turned to the second position, the notch 3321 can avoid the support beam 13, so as to prevent the inclined plate 332 from interfering with the support beam 13. Specifically, when the support assembly 3 is turned to the second position, the support beam 13 will interfere with an inclined plate 332. A notch 3321 is provided at the interference position of the inclined plate 332, so that the support beam 13 can be accommodated in the notch 3321. This ensures that the connecting column 31 of the support assembly 3 can smoothly abut against the longitudinal beam 12 of the base 1 without hindrance, so as to better complete the folding of the rack.

As shown in FIG. 3 , the base 1 is also provided with forklift holes 15 along the circumferential direction, and the forklift holes 15 are for forklift tines to enter so that the forklift can move the entire folding rack.

As shown in FIG. 2 and FIG. 4 , a hook 16 is also provided on the outer side of each corner column 2 , so that a sling can be hooked on the hook 16 to realize the lifting of the rack.

By providing the forklift hole 15 and the hook 16, the material rack can be lifted and transported by a forklift, as well as hoisted and transported, which is conducive to flexible transportation of the material rack.

As shown in FIG4 , a gasket 5 is further provided on the longitudinal beam 12 and the support beam 13 of the base 1. The gasket 5 has a buffering and shock-absorbing effect to protect the folding rack and extend the service life of the folding rack. When the support assembly 3 moves to the second position, the support frame 34 and the connecting column 31 of the support assembly 3 abut against the base 1 under the buffering effect of the gasket 5, thereby avoiding damage to the support assembly 3 or the base 1.

The folding rack further includes a rib plate 6 to enhance the bearing strength of the folding rack. Specifically, the rib plate 6 includes but is not limited to being provided at the connection between the support frame 34 and the connecting column 31, and can also be provided at the connection between the inclined plate 332 and the support frame 34, the connection between the baffle plate 22 and the second side plate 212, etc., as long as the bearing strength of the folding rack can be enhanced.

The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive.
