[0001] The utility model relates to the technical field of metal processing equipment, and more particularly to a foldable material rack. Background technology:

[0002] Some existing metal castings need to be placed on a rack after processing for easy management;

[0003] Different products require different racks, which requires enough space to place the racks. When such products are not produced, these racks will be empty, and the racks themselves take up a relatively large space. If they are not used, space will be wasted, and the space cannot be reduced to facilitate the placement of other objects or the placement and use of racks with other objects, and the space utilization rate is greatly reduced. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a foldable material rack, which can be folded and folded when not in use, thereby reducing the space it occupies, so that the empty space can be used for other objects or other material racks with objects placed on them, meeting needs and having high flexibility.

[0008] The hook body is put into the sleeve hole formed at the end of the telescopic rod of the quick clamp by using the quick clamp to achieve fixation, so that the two ends of the horizontal support beam are pressed against and fixed on the two positioning blocks, thereby achieving support between the two upper vertical columns.

[0009] A vertically extending sleeve member is fixed on the vertical support column, and the sleeve member includes a vertical inner plate body, and side bending portions bent outward are formed on the front and rear sides of the vertical inner plate body, and the vertical inner plate body is tightly attached to the inner side wall of the corresponding vertical support column, and the side bending portions are located at the front and rear side walls of the corresponding vertical support column and are tightly attached to each other, and the top of the sleeve member extends out of the top of the vertical support column and is fixed at the lower part of the corresponding upper vertical column;

[0010] The bottom of the sleeve is movably connected to the corresponding vertical support column through a hinge;

[0011] The lower inner side wall of the upper vertical column is fixed to the upper part of the corresponding vertical inner plate body, and the upper part of the side bending part is fixed to the front side wall or the rear side wall of the lower part of the upper vertical column.

[0023] For example, see Figures 1 to 7 As shown, a foldable material rack comprises a horizontally arranged bottom frame 10, with vertical support columns 11 fixed at the four corners of the bottom frame 10, and an upper vertical column 12 movably connected to the vertical support column 11. Its specific structure is that a vertically extending sleeve member 13 is fixed to the vertical support column 11, and the sleeve member 13 comprises a vertical inner plate body, and the front and rear sides of the vertical inner plate body are formed with side bending portions bent outwardly, and the middle to the lower part of the vertical inner plate body is tightly attached to the inner side wall of the corresponding vertical support column 11, and the side bending portions are located at the front and rear side walls of the corresponding vertical support column 11 and are tightly attached to each other, and the top of the sleeve member 13 extends out of the top of the vertical support column 11 and is fixed to the lower part of the corresponding upper vertical column 12;

[0024] The bottom of the vertical inner plate of the sleeve 13 is movably connected to the inner side wall of the corresponding vertical support column 11 through a hinge;

[0025] The lower inner side wall of the upper vertical column 12 is fixed to the upper part of the corresponding vertical inner plate, and the upper part of the side bending portion is fixed to the front side wall or the rear side wall of the lower part of the upper vertical column 12.

[0026] The middle part of the two side bends 131 of the sleeve 13 is formed with a through hole extending forward and backward, which corresponds to and communicates with the through holes formed on the front and rear side panels of the upper part of the vertical support column 11, and the positioning pin rod 3 is inserted into the corresponding through hole and the through hole of the corresponding side bend 131 (at this time, the outer wall of the positioning pin rod 3 matches the inner wall of the through hole of the corresponding side bend 131, and the two are tightly attached to each other, so that after the positioning pin rod 3 is inserted, there is friction between it and the inner wall of the through hole to prevent the positioning pin rod 3 from slipping out. This pin hole connection method is a conventional structure and will not be described in detail here). One end of the positioning pin rod 3 extends out of the corresponding through hole and is installed with a ring body 4.

[0027] When folding, it is only necessary to pull out the positioning pin rod 3 , and then the sleeve member 13 and the corresponding upper vertical column 12 can be folded inwards and leaned against the bottom frame 10 .

[0028] Furthermore, at least one transverse connecting beam 20 is fixed between the two upper vertical columns 12 on the left, and at least one transverse connecting beam 20 is also fixed between the two upper vertical columns 12 on the right. In this embodiment, two aligned transverse connecting beams 20 are provided on each side, and the two ends of the upper transverse connecting beam 20 are fixed to the middle of the relative wall surfaces of the corresponding two upper vertical columns 12, and the two ends of the lower transverse connecting beam 20 are fixed to the corresponding side bending parts 131 of the sleeve parts 13 fixed on the lower parts of the corresponding two upper vertical columns 12.

[0029] Each transverse connecting beam 20 is movably connected to a side guardrail frame 30, which is located on the top surface of the corresponding transverse connecting beam 20. Latch pins 40 are installed on the outer side walls of the front and rear ends of the side guardrail frame 30. A corresponding stopper 1 is fixed to the outer side wall of the corresponding upper vertical column 12, and the end of the latch pin 40 is inserted into the slot on the corresponding stopper 1.

[0030] A transverse support beam 50 is installed between the two corresponding upper vertical columns 12 on the left and right. The two ends of the transverse support beam 50 are pressed against the positioning blocks 121 fixed on the inner walls of the corresponding upper vertical columns 12. A quick clamp 60 is installed at the end of the transverse support beam 50. A hook body 2 is fixed to the positioning block 121 or the upper part of the inner wall of the upper vertical column 12 (in this embodiment, the hook body 2 is fixed to the upper part of the inner wall of the upper vertical column 12), and the hook body 2 is sleeved in the sleeve hole 62 formed at the end of the telescopic rod 61 of the quick clamp 60.

[0031] Furthermore, a support block 111 is fixed to the bottom end of the vertical support column 11. An upwardly extending socket is formed in the middle of the bottom surface of the support block 111, which mates with the top end of the upper vertical column 12. This structural arrangement allows two of the present embodiments to be stacked, with the top end of the lower upper vertical column 12 inserted into the socket of the upper support block 111 and pressed against the top end of the socket, thereby achieving stacking.

[0032] Furthermore, a plurality of bent placement blocks 21 are fixed to the top surface of the inner side of the transverse connecting beam 20, and a plurality of inner positioning blocks 32 are fixed on the inner wall of the side guardrail frame 30. A vertical card groove 33 running through the inner wall of the inner positioning block 32 is formed, and the vertical card groove 33 corresponds to the placement groove on the top surface of the corresponding bent placement block 21.

[0033] Furthermore, the bottom surface of the side guardrail frame 30 rests on the top surface of the corresponding transverse connecting beam 20, and a hinge shaft portion 34 is fixed on the outer outer wall of the side guardrail frame 30, and the middle part of the hinge shaft portion 34 is inserted into the sleeve portion fixed on the outer wall of the transverse connecting beam 20 below it.

[0034] Furthermore, two guide sleeves 35 are fixed to the outer wall of the front or rear end of the side guardrail frame 30. A latch 40 is inserted into the corresponding two guide sleeves 35. One end of the latch 40 extends out of one guide sleeve 35 and is inserted into the corresponding slot of the stopper 1. This end of the latch 40 is bent to form a vertical bend 41, which extends vertically downward and is located on the lower side of the end surface of the corresponding guide sleeve 35. The other end of the latch 40 extends out of the other guide sleeve 35 and is fixed with a vertical bend on one side of a hand-held bend 42. The end of the vertical bend on the other side of the hand-held bend 42 is welded to the middle of the latch 40 and is located between the two corresponding guide sleeves 35. The vertical distance between the top and bottom surfaces of the vertical bend 41 of the latch 40 is less than the distance between the top and bottom surfaces of the slot on the stopper 1.

[0035] Furthermore, the quick clamp 60 includes a connecting seat 63, which is fixed to the inner side wall of the end of the corresponding transverse support beam 50. The connecting seat 63 is movably connected to a pull rod 64 through a hinge shaft. The middle part of the pull rod 64 is movably connected to one end of a telescopic sleeve 65 through a hinge shaft. The telescopic sleeve 65 is inserted into the corresponding connecting seat 63. A telescopic through hole is formed in the middle of the end plate of the other end of the telescopic sleeve 65. The telescopic rod 61 is inserted into the telescopic through hole. The outer end of the telescopic rod 61 extends out of the corresponding telescopic through hole and is formed with a fixed width greater than the telescopic through hole. The positioning plate 66 has a sleeve hole 62 that runs through the front and back in the middle of the positioning plate 66. A guide plate 67 is fixed to the inner end of the telescopic rod 61. The extended guide portions at the upper and lower ends of the guide plate 67 are inserted into the left and right extending guide grooves formed on the upper and lower wall plates of the telescopic sleeve 65. A buffer spring 68 is inserted into the telescopic rod 61. One end of the buffer spring 68 focuses on the guide plate 67 and the other end focuses on the inner wall surface of the end plate corresponding to one end of the telescopic sleeve 65. At this time, the buffer spring 68 is compressed, and one side of the hook body 2 is pressed against the inner wall of the corresponding sleeve hole 62 to achieve compression.

[0036] When the present embodiment is in use, the latch 40 can be flipped upwards, and the vertical bending portion 41 of the latch 40 can be removed from the slot on the corresponding limiting member 1. At this time, the side guardrail frame 30 can be flipped outwards.

[0037] When the present embodiment is not in use, it can be folded by pulling the pull rod 64 of the quick clamp 60 to move the telescopic sleeve 65 outward. At this time, the buffer spring 68 elastically recovers, and at this time, one side of the hook body 2 no longer presses against the inner wall of the corresponding sleeve hole 62, so that the positioning plate 66 of the telescopic rod 61 can be removed from the hook body 2, and the corresponding transverse support beam 50 can be removed. Then, the four positioning pins 3 are pulled out, and the sleeve part 13 and the corresponding upper vertical column 12 can be folded inward, thereby realizing the folding and folding of the components on the left and right sides, which greatly reduces the space occupied by the present embodiment. At the same time, the present embodiments of the same specifications and size can be stacked up and placed, which is very convenient.

[0038] The saved space can be used to place other objects or other racks with materials, meeting needs and providing high flexibility of use.
