Description

Technical Field

[0001] This utility model relates to the field of logistics packaging and transportation technology, and in particular to a shock-absorbing pallet that prevents displacement. Background Technology

[0002] With the development of high technology, more and more high-precision equipment on the market needs to use shock-absorbing pallets with standardized locking structures during transportation. Usually, the locking structure of shock-absorbing pallets is directly fixed with traditional bolts or screws, which leaves holes and grooves on the panel. When the supported items are heavy, the locking structure may puncture the panel and come into contact with the lower surface of the supported object, resulting in equipment damage.

[0003] To solve the above problems, there is an urgent need for a locking structure that prevents dislodgement, ensuring the support strength of the shock-absorbing tray without causing damage to the equipment. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a shock-absorbing tray that prevents displacement.

[0005] The technical solution of this utility model is a shock-absorbing tray for preventing displacement, which includes a panel for support and a support structure for support; the support structure includes a buffer, a crossbeam and a bottom beam;

[0006] The buffer is secured with fasteners; the crossbeam is connected to the bottom of the panel and then fixed to the top of the buffer; the bottom beam is fixed to the bottom of the buffer.

[0007] After the crossbeams and bottom beams are staggered, a cross structure is formed at the bottom of the panel; and a space is formed at the bottom of the panel to facilitate the insertion of forklifts; the forklift is inserted under the panel in a direction parallel to the bottom beam to lift the pallet.

[0008] Preferably, the upper surface of the panel is smooth and has no openings.

[0009] Preferably, multiple sets of crossbeams are arranged in parallel and evenly distributed on the bottom surface of the panel; the crossbeams are bonded and fixed to the panel.

[0010] Preferably, the buffer includes a first fixing block, a shock-absorbing block, and a second fixing block;

[0011] The first and second fixing blocks are located at the upper and lower ends of the damping block, respectively, and are glued and fixed to the damping block.

[0012] Preferably, the first fixing block, the shock-absorbing block, and the second fixing block are all provided with through holes; fasteners pass through the through holes to perform secondary fixing on the first fixing block, the shock-absorbing block, and the second fixing block.

[0013] Preferably, the fasteners include four-pronged screws, bolts, and spring washers;

[0014] The four-pronged screw is pre-embedded on the first fixing block and located at the through hole;

[0015] The spring washer is fitted onto the bolt; the bolt passes through the through holes of the second fixing block and the shock absorber in sequence, and is connected with the four-jaw screw thread to lock the buffer.

[0016] Preferably, the spring washer is an open ring.

[0017] Preferably, the bottom beam has a circular hole with a diameter larger than that of the spring washer; the head of the bolt is located inside the circular hole.

[0018] Preferably, the crossbeam has a circular hole with the same diameter as the bolt; after the crossbeam and the buffer are assembled, the circular hole presses down on the edge of the four-prong nut to form a limiting structure.

[0019] Preferably, the panel, crossbeam, first fixing block, second fixing block, and bottom beam are all made of plywood;

[0020] The damping block is a rubber damping block.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] This utility model modifies the existing shock-absorbing tray; optimizes the structure of the buffer and the connection method of the fasteners; the buffer is locked twice by the fasteners; and the connection of other parts is more secure; when supporting heavy objects, it effectively distributes the load on the panel evenly to each crossbeam, and then transfers it to the buffer through the crossbeams, and then to the bottom beam, thereby improving the load-bearing capacity of the entire panel.

[0023] Its special structural design allows each part of the cushioning component to work together to share the pressure when supporting heavy objects, effectively preventing the four-claw screws from jumping up. When goods are stacked on the panel, the cushioning component is compressed, ensuring that the bolts do not directly touch the objects below, thus avoiding damage to the supported items.

[0030] Example 1

[0031] like Figure 1 As shown, this utility model proposes an anti-displacement shock-absorbing pallet, including a panel 1 for support and a support structure for further support; the support structure includes a buffer, a crossbeam 2, and a bottom beam 6; the buffer is locked using fasteners 7; the crossbeam 2 is connected to the bottom of the panel 1 and fixed to the top of the buffer; the bottom beam 6 is fixed to the bottom of the buffer; the crossbeam 2 and the bottom beam 6 are staggered to form a cross structure at the bottom of the panel 1; and a space is formed at the bottom of the panel 1 for easy forklift insertion; the forklift is inserted under the panel 1 along a direction parallel to the bottom beam 6 to lift the pallet. Figure 1 As shown, the upper surface of panel 1 is smooth and without openings. In this embodiment, the bottom beam 6 provides support at the bottom, the buffer is set on the bottom beam 6, and the top crossbeam 2 forms a cross-shaped intersecting structure with the bottom beam 6, located between panel 1 and the buffer; this can effectively distribute the load on panel 1 evenly to each crossbeam 2, and then transfer it to the buffer through the crossbeam 2, and then to the bottom beam 6, thereby improving the load-bearing capacity of the entire panel 1.

[0032] like Figure 2 As shown, in this embodiment, multiple sets of crossbeams 2 are arranged in parallel and evenly distributed on the bottom surface of panel 1; the crossbeams 2 are bonded and fixed to panel 1; after the panel 1 supports a heavy object, the pressure generated will press the panel 1 and the crossbeams 2 together, and with the adhesive, the connection between the panel 1 and the crossbeams 2 will be more secure; when using a forklift to move pallets and items, since the forklift is inserted below the crossbeams 2, the contact surface between panel 1 and crossbeams 2 is always subjected to the pressure of the items during the entire transportation process, maintaining a tight connection.

[0033] like Figure 3 As shown, in this embodiment, the buffer includes a first fixing block 3, a shock-absorbing block 4, and a second fixing block 5. The first fixing block 3 and the second fixing block 5 are respectively located at the upper and lower ends of the shock-absorbing block 4 and are glued and fixed to the shock-absorbing block 4. The first fixing block 3, the shock-absorbing block 4, and the second fixing block 5 are all provided with through holes; the fastener 7 passes through the through holes to perform secondary fixation on the first fixing block 3, the shock-absorbing block 4, and the second fixing block 5.

[0034] like Figure 4 As shown, the fastener 7 includes a four-pronged screw 71, a bolt 72, and a spring washer 73. The four-pronged screw 71 is pre-embedded in the first fixing block 3 and located at the through hole. The spring washer 73 is fitted onto the bolt 72. The bolt 72 passes through the through holes of the second fixing block 5 and the shock absorber block 4 in sequence, and is threadedly connected to the four-pronged screw 71 to lock the buffer. The spring washer 73 is an open ring. The bottom beam 6 has a circular hole with a diameter larger than that of the spring washer 73. The head of the bolt 72 is located in the circular hole. The crossbeam 2 has a circular hole with the same diameter as the bolt 72. After the crossbeam 2 is assembled with the buffer, the circular hole presses down on the edge of the four-pronged nut 71 to form a limiting structure.

[0035] In this embodiment, when using fastener 7 to lock the buffer component a second time, holes are first drilled in the first fixing block 3, the shock-absorbing block 4, and the second fixing block 5; and a processing device is used to pre-press the four-pronged screw 71 into the through hole of the first fixing block 3, ensuring that the four-pronged screw 71 is in a compacted state; then, the bolt 72 with spring washer 73 is passed through the through holes on the second fixing block 5 and the shock-absorbing block 4 in sequence, and connected with the threaded four-pronged screw in the first fixing block 3 to maintain a fixed state; the spring washer 73 can prevent the threaded connection from loosening; and the bottom beam 6 is provided with a diameter greater than The spring washer 73 has a circular hole of the same diameter. During installation, the bottom beam 6 is pre-glued to the second fixing block 5, so the larger circular hole facilitates bolt installation and also provides sufficient space for maintenance. The crossbeam 2 has a circular hole of the same diameter as the bolt 72. After the crossbeam 2 is assembled with the buffer, the circular hole presses down on the edge of the four-prong nut 71, forming a limiting structure. Utilizing the weight of the panel 1 and the supporting object, the four-prong nut 71 is prevented from jumping out. When goods are stacked on the panel 1, the buffer is compressed, ensuring that the bolt does not directly contact the lower object. The upper and lower fixing blocks effectively provide stability.

[0036] As a preferred embodiment, panel 1, crossbeam 2, first fixing block 3, second fixing block 5, and bottom beam 6 are all made of plywood; shock-absorbing block 4 is a rubber shock-absorbing block. Plywood is low-cost and easy to manufacture, and can be made into appropriate sizes as needed; the rubber shock-absorbing block is a rigid shock-absorbing block that provides support while being deformable to provide cushioning. This allows for easy separation of the cushioning component from the panel or bottom beam if any part is damaged during transportation, enabling replacement of the damaged part; the cushioning component is reusable.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
