[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figures 1 to 3 In an embodiment of the utility model, an assembled plastic frame includes a trapezoidal plastic frame 1 having a frame body 101, and lifting grooves 102 are integrally formed on both sides of the frame body 101, and 7-shaped storage grooves 103 are integrally formed at both ends of the inner wall of the frame body 101, and the top of the 7-shaped storage groove 103 passes through the top and one end of the frame body 101;
[0028] The frame 101 and the 7-shaped storage slot 103 are provided with a limited support assembly 2, which includes a support unit and a reset unit.
[0029] The support unit in the expanded state is used to limit the two stacked frames 101 to prevent the upper frame 101 from contacting the goods inside the lower frame 101. The support unit in the collapsed state does not interfere with the connection of the two stacked frames 101. The reset unit is used to provide reset power and guidance for the support unit in the collapsed state.
[0030] The support unit includes a bottom plate 201, a rotating connecting member 203, and a 7-shaped support plate 204;
[0031] The bottom plate 201 is received inside the frame 101 and is close to the bottom of the inner wall of the frame 101. The rotating connecting members 203 are symmetrically fixed to the two ends of the bottom plate 201 in pairs and extend to the inside of the 7-shaped receiving groove 103.
[0032] The 7-shaped support plate 204 is received in the 7-shaped receiving groove 103 and is rotatably connected between the two rotating connectors 203 , and the top horizontal portion of the 7-shaped support plate 204 extends to the outer end of the frame 101 ;
[0033] An inclined surface is formed on the inner side of the corner of the 7-shaped support plate 204, and the inclined surface is in contact with the top edge of the 7-shaped storage groove 103. When the bottom plate 201 moves downward to pull the 7-shaped support plate 204 downward, the top edge of the 7-shaped storage groove 103 is squeezed by the inclined surface, so that the top lateral part of the 7-shaped support plate 204 rotates to the inside of the frame 101, so as to form support for the bottom of the frame 101 above;
[0034] The reset unit includes a plastic spring 202 and an inclined guide groove 205;
[0035] The plastic spring piece 202 is distributed between the bottom of the bottom plate 201 and the bottom of the frame 101, and the plastic spring piece 202 is used to provide a reset thrust for the bottom plate 201 after it moves downward;
[0036] The inclined guide groove 205 is symmetrically opened on both sides of the inclined surface of the 7-shaped support plate 204, and the limiting columns 104 are fixedly connected to both sides of the inner wall of the 7-shaped storage groove 103. The limiting columns 104 are inserted into the inner side of the inclined guide groove 205. The inclined guide groove 205 is slidably connected with the limiting columns 104 to provide guidance for the movable reset of the 7-shaped support plate 204.
[0037] In this embodiment, when no goods are placed in the plastic frame, the bottom plate 201 is at the highest point, and the 7-shaped support plate 204 is stored in the 7-shaped storage groove 103. When one frame 101 is placed in another frame 101, the 7-shaped support plate 204 will not block the placed frame 101, that is, the two adjacent frames 101 can be mutually nested and stored, effectively reducing the storage space;
[0038] When goods are placed in the plastic frame, the goods directly contact the bottom plate 201 and squeeze it, causing the bottom plate 201 to move downward to squeeze the plastic spring sheet 202 to shrink, and at the same time drive the 7-shaped support plate 204 to move downward. At this time, through the squeezing of the inner inclined surface of the corner of the 7-shaped support plate 204 and the top edge of the 7-shaped storage groove 103, and the guiding cooperation between the inclined guide groove 205 and the limiting column 104, the 7-shaped support plate 204 is rotated a certain angle toward the inside of the frame 101 with the rotating connecting piece 203 as the center. At this time, the top lateral part of the 7-shaped support plate 204 is located inside the frame 101. In this way, when another frame 101 is stacked on the top of this frame 101, the bottom of the other frame 101 is limited by the top lateral part of the 7-shaped support plate 204, that is, it will not cause squeezing of the goods inside the frame 101, effectively ensuring the safe storage of the goods.
[0039] Please refer to Figures 1 to 3 There are multiple plastic spring pieces 202 , and the total elastic force of the multiple plastic spring pieces 202 is greater than the total gravity of the bottom plate 201 , the rotating connecting piece 203 , and the 7-shaped supporting plate 204 .
[0040] In this embodiment: through this structure, after all the goods on the bottom plate 201 are taken away, the bottom plate 201, the rotating connecting piece 203, and the 7-shaped support plate 204 will move upward under the action of the restoring elastic force of the plastic spring piece 202, and the 7-shaped support plate 204 will rotate outward under the guidance of the inclined guide groove 205 and the limiting column 104, which is convenient for subsequent stacking and storage operations.
[0041] Please refer to Figures 1 to 3 A protrusion is formed at the bottom of one end of the top horizontal part of the 7-shaped support plate 204. After the 7-shaped support plate 204 moves downward, the protrusion is attached to the end surface of the outer wall of the frame 101.
[0042] In this embodiment, the protrusion is attached to the outer wall end surface of the frame 101 to provide a pulling force for the 7-shaped support plate 204 , so that the 7-shaped support plate 204 can provide sufficient supporting force for the frame 101 above.
[0043] Please refer to Figures 1 to 3 The outer wall size of the bottom plate 201 matches the inner wall size of the bottom of the frame 101 , and the outer wall size of the bottom of the frame 101 is larger than the inner wall size of the cross section of the frame 101 at the initial position of the bottom plate 201 .
[0044] In this embodiment: the bottom plate 201 can be smoothly moved downward by matching the outer wall size of the bottom plate 201 with the bottom inner wall size of the frame 101;
[0045] By making the outer wall size of the bottom of the frame 101 larger than the inner wall size of the cross section of the frame 101 at the initial position of the bottom plate 201, when the upper frame 101 is placed inside the lower frame 101, the bottom of the upper frame 101 will not contact the bottom plate 201 inside the lower frame 101.
[0046] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
