DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Combine the following Figure 1-Figure 7 A fixing device for an open-top box pallet according to an embodiment of the present invention is described, comprising: a first support rod assembly 100, the first support rod assembly 100 comprising a first positioning beam 110 and a connecting portion 120 and a limiting portion 130 fixed to the first positioning beam 110, the first positioning beam 110 is supported between a door column of a box body 300 and a corner piece 440 of a pallet 400 adjacent to a box door 310, the connecting portion 120 is used for connecting to the door column of the box body 300, and the limiting portion 130 is used for limiting the corner piece 440 of the pallet 400 adjacent to a box door 310.

[0030] Specifically, the door column is arranged on one side of the box door 310 of the box body 300. The number of the first support bar assemblies 100 is consistent with the number of the corner pieces 440 on the side of the tray 400 adjacent to the box door 310, and the first support bar assemblies 100 and the corner pieces 440 are arranged one by one, but in order to ensure the fixing effect of the fixing device, at least two first support bar assemblies 100 are arranged to fix the corner pieces 440 at both ends of the cross beam 420 of the tray 400. Generally, a rectangular tray 400 is installed with a corner piece 440 at each of its four corners, and a corner piece 440 is installed at each of the two ends of the side adjacent to the box door 310, so the number of the first support bar assemblies 100 is also two, and the tray 400 can be fixed in the box body 300 by connecting the corner pieces 440 and the box door 310 respectively, so that the tray 400 can be fixed in the box body 300 without moving.

[0031] The first positioning beam 110 of the first support rod assembly 100 is supported by a steel structure, and mainly serves to support and install the connecting portion 120 and the limiting portion 130. The connecting portion 120 is used to connect the door column, and the limiting portion 130 is used to limit the corner piece 440 of the pallet 400, thereby fixing the pallet 400.

[0032] When designing the size of the pallet 400, it is necessary to ensure that its size is smaller than the size of the top opening of the open top box, so that the pallet 400 can be placed from the top of the open top box into the open top box by hoisting. During the hoisting process, the first support rod assembly 100 can be placed on the pallet 400 (such as Figure 1 After the tray 400 is placed in the box 300, the first support rod assembly 100 is removed, the connecting portion 120 is connected to the door column of the box 300, and the corner piece 440 of the tray 400 near the door 310 is placed in the limiting portion 130 to limit its movement, so that the tray 400 is fixed in the box 300.

[0033] The embodiment of the present invention provides a fixing device for an open top box pallet, which reduces the size of the pallet 400 so that it can be placed in the box body 300 by hoisting. The connecting portion 120 is connected to the door column of the box body 300, and the corner piece 440 of the pallet 400 is placed in the limiting portion 130 accordingly to limit its movement, so that the pallet 400 is fixed in the box body 300. By using the fixing device for an open top box pallet of the embodiment of the present invention, the pallet 400 can be placed in the box by hoisting, and the pallet 400 can be stably fixed in the box, thereby improving the packing efficiency and safety.

[0034] The connecting portion 120 includes a strip square bolt 121 and a first square bolt fixing plate 122. The first square bolt fixing plate 122 is fixed to the end of the first positioning beam 110. The strip square bolt 121 is fixed to the first square bolt fixing plate 122. The strip square bolt 121 is used to be inserted into the groove 311 of the door column of the box body 300. Specifically, the groove 311 of the door column in this embodiment is a vertical groove 311. When in use, the strip square bolt 121 can be slid from the top of the groove 311 to the bottom of the groove 311, so that the strip square bolt 121 is clamped inside the groove 311 to limit the horizontal movement of the two. If the strip square bolt 121 needs to be taken out, the strip square bolt 121 is slid upward from the bottom of the groove 311 and taken out from the top of the groove 311. The first square bolt fixing plate 122 is used to fix the strip square bolt 121. The strip square bolt 121 can be fixed to the first square bolt fixing plate 122 by bolts.

[0035] The limiting portion 130 includes a buffer pad 131 and a first limiting clamping plate 132, which are arranged along the axial gap of the first positioning beam 110 and form a first limiting groove 150 for limiting the angle piece 440. In this embodiment, the buffer pad 131 and the first limiting clamping plate 132 are used to limit and fix the angle piece 440, so that the angle piece 440 is in the first limiting groove 150, the first limiting clamping plate 132 and the angle piece 440 are in rigid contact, and the buffer pad 131 and the angle piece 440 are in elastic contact. The buffer pad 131 can be made of a rubber pad or a material with a certain elasticity.

[0036] The limiting portion 130 further includes a buffer pad fixing plate 133, which is fixed to the first positioning beam 110, and the buffer pad 131 is mounted on the buffer pad fixing plate 133. Specifically, the buffer pad fixing plate 133 in this embodiment is used to fix the buffer pad 131, and the buffer pad 131 can be fixed to the buffer pad fixing plate 133 by fixing screws.

[0037] Among them, a second limiting groove 160 extending along the axial direction of the first positioning beam 110 is formed between the first limiting card plate 132 and the first positioning beam 110, which is used to match the side beam installed on the tray 400. Specifically, the side beam of the tray 400 includes a cross beam 420 and a longitudinal beam 430. The second limiting groove 160 in this embodiment can be matched and installed with the longitudinal beam 430 of the tray 400, specifically: the longitudinal beam 430 is pushed into the second limiting groove 160 to ensure that the longitudinal beam 430 does not swing left and right in the second limiting groove 160, so that the first positioning beam 110 is parallel to the longitudinal beam 430, which can further ensure that the tray 400 is parallel and stably fixed inside the box body 300.

[0038] The limiting portion 130 further includes a reinforcing rib 134, one end of which is supported on the first positioning beam 110, and the other end is supported on the buffer pad fixing plate 133. The reinforcing rib 134 in this embodiment is used to strengthen the connection stability between the buffer pad fixing plate 133 and the first positioning beam 110, so as to ensure that the buffer pad fixing plate 133 does not shake easily.

[0039] The first support rod assembly 100 further includes a first reinforcing plate 140, one end of which is supported on the first square bolt fixing plate 122, and the other end is supported on the first positioning beam 110. The first reinforcing plate 140 in this embodiment is used to strengthen the connection stability between the first square bolt fixing plate 122 and the first positioning beam 110, so as to ensure that the first square bolt fixing plate 122 does not shake easily.

[0040] The fixing device for an open top container pallet of this embodiment further includes a second support bar assembly 200, which includes a second positioning beam 210, a receiving portion 220 and a positioning portion 230 fixed on the second positioning beam 210, the second positioning beam 210 is arranged between the end wall 330 of the box body 300 and the corner piece 440 of the pallet 400 adjacent to the end wall 330, and the receiving portion 220 faces the end wall 330 of the box body 300, and the positioning portion 230 is connected to the corner piece 440 of the pallet 400 adjacent to the end wall 330. The second support bar assembly 200 of this embodiment is arranged opposite to the first support bar assembly 100, that is, the first support bar assembly 100 is adjacent to the box door 310 of the box body 300, and the second support bar assembly 200 is adjacent to the end wall 330 of the box body 300 opposite to the box door 310. In this embodiment, the pallet 400 is fixed by setting at least four support rod assemblies (i.e., including two first support rod assemblies 100 and two second support rod assemblies 200). The number of the second support rod assemblies 200 is selected according to the same principle as the first support rod assemblies 100, and also matches the number of the corner pieces 440.

[0041] Specifically, the second positioning beam 210 of the second support rod assembly 200 is supported by a steel structure, and mainly serves the function of supporting and installing the receiving portion 220 and the positioning portion 230. The receiving portion 220 faces the end wall 330 of the box body 300. When the pallet 400 moves, it replaces the pallet 400 in contact with the end wall 330 of the box body 300, thereby avoiding direct contact between the pallet 400 and the end wall 330 of the box body 300 and causing damage to the pallet 400. The positioning portion 230 is used to position and connect with the corner piece 440 of the pallet 400, so that the second support rod assembly 200 and the pallet 400 are relatively fixed.

[0042] The receiving portion 220 includes a rectangular square bolt 221 and a second square bolt fixing plate 222. The second square bolt fixing plate 222 is fixed to the end of the second positioning beam 210, and the rectangular square bolt 221 is fixed to the second square bolt fixing plate 222. The rectangular square bolt 221 of this embodiment has a larger receiving area than the strip square bolt 121.

[0043] The positioning portion 230 includes a second limiting clamp plate 231 and a third limiting clamp plate 232, which are arranged along the axial gap of the second positioning beam 210 and form a third limiting groove 250 for limiting the position of the corner piece 440. Different from the first support rod assembly 100, the second limiting clamp plate 231 and the third limiting clamp plate 232 of the second support rod assembly 200 are in rigid contact with the corner piece 440 and do not have a vibration reduction effect.

[0044] During the hoisting process, the second support bar assembly 200 can be placed on the pallet 400. After the pallet 400 is placed in the box 300, the second support bar assembly 200 is removed, and the corner piece 440 on the side of the pallet 400 adjacent to the end wall 330 is correspondingly placed in the positioning portion 230, so that the second support bar assembly 200 and the pallet 400 are relatively fixed. When the first support bar assembly 100 fails, the rectangular square bolt 221 of the second support bar assembly 200 can replace the pallet 400 to contact the inner wall of the box 300 to avoid damage to the pallet 400.

[0045] Furthermore, the second support rod assembly 200 further includes a second reinforcing plate 240, one end of which is supported on the second square bolt fixing plate 222, and the other end is supported on the second positioning beam 210. The second reinforcing plate 240 in this embodiment is used to strengthen the connection stability between the second square bolt fixing plate 222 and the second positioning beam 210, so as to ensure that the second square bolt fixing plate 222 does not shake easily.

[0046] Furthermore, a fourth limiting groove 260 extending axially along the second positioning beam 210 is formed between the second limiting card plate 231 and the second positioning beam 210, as well as between the third limiting card plate 232 and the second positioning beam 210, and is used to match the longitudinal beam 430 of the installation tray 400. Specifically, the longitudinal beam 430 is pushed into the fourth limiting groove 260 to ensure that the longitudinal beam 430 does not swing left and right in the fourth limiting groove 260, so that the second positioning beam 210 is parallel to the longitudinal beam 430, which can further ensure that the tray 400 is parallel and stably fixed inside the box body 300.

[0047] like Figure 1 , Figure 2 and Figure 7 As shown, this embodiment discloses a container assembly, including: a box body 300 (i.e., a container), a pallet 400, and a fixing device for an open top container pallet as in the above embodiment; wherein,

[0048] The box body 300 is formed by side walls 320, end walls 330 and a box door 310;

[0049] The tray 400 is placed in the box body 300 , and a lap plate 410 and a hanging seat 450 are provided on the tray 400 for lap-mounting the first support rod assembly 100 .

[0050] Furthermore, the box door 310 is provided with a groove 311 for the bar-shaped square bolt 121 to be pushed in, so that the connecting portion 120 is engaged with the box door 310 of the box body 300, and the horizontal movement of the two is restricted. It can be understood that the lap plate 410 and the hanging seat 450 can also be used to overlap and place the second support rod assembly 200. The lap plate 410 is arranged horizontally, and the hanging seat 450 and the lap plate 410 are used in conjunction to overlap the first positioning beam 110 and the second positioning beam 210.

[0051] The container assembly of this embodiment adopts a first support rod assembly 100 connected between the box door 310 of the box body 300 and the corner piece 440 of the pallet 400, so that the size of the pallet 400 meets the requirements of lifting, and the pallet 400 can be stably fixed in the box body 300, thereby improving the packing efficiency and safety.
