Description

Technical Field

[0001] The present invention belongs to the technical field of carrying trays, and particularly relates to a repairable tray. Background Art

[0002] Traditional logistics trays mostly adopt an integral structure, which is integrally formed by wooden boards, plastics or metal materials. Although such trays have a certain load-bearing capacity, they occupy a large space during unloaded transportation, resulting in high storage costs, and it is difficult to meet the flexible requirements of different sizes of goods. To solve this problem, detachable trays have emerged in the prior art, which are modularly assembled through connecting parts such as bolts and buckles. All of our current tray products are integral. During the tray design process, in order to meet the weight requirements of the carried objects, the tray panel is usually designed to be relatively thick to directly meet the usage requirements of the tray. However, during the use of this kind of tray, once a part is damaged, it will be discarded, resulting in serious waste.

[0003] Chinese Patent 201920201279.8 discloses a detachable tray, including longitudinally connected slats, laterally connected slats and foot blocks. The longitudinally connected slats and the laterally connected slats respectively have two continuous grooves along the length direction, and their edges are bent inward to form flanges; the foot block includes first support columns on both sides and a second support column in the middle. The first support columns and the second support column are arranged in parallel and have the same height; between the first support column and the second support column is a fixing groove, which cooperates with the groove of the longitudinally connected slat, and a fixed connection part is arranged at the bottom of the fixing groove; on the outer vertical surface of the first support column, there is a clamping groove for cooperating with the flange to clamp the longitudinally connected slat. The above device uses the physical clamping of the flange and the clamping groove, without an active locking mechanism. Under static load, the friction force can maintain the connection, but during transportation, impact or repeated loading and unloading, the contact surface between the flange and the clamping groove is prone to produce small displacements, which will cause the gap to expand after long-term accumulation, the connection to become loose, and the overall structural rigidity to decrease.

[0004] As a deficiency of the prior art, the overall connection of the transportation tray is not firm, and it is not easy to disassemble and repair when damaged. In the technical field of carrying trays, the prior art lacks a tray with high connection strength and capable of being quickly disassembled and repaired. Summary of the Invention

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "left side", "right side", "upper part", "lower part", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the components, so they should not be construed as limitations on the present invention. The specific dimensions adopted in this embodiment are only for illustrating the technical solution and do not limit the protection scope of the present invention.

[0053] This embodiment provides a repairable tray, which can effectively improve the connection strength of the tray and the disassembly and repair efficiency.

[0054] As Figures 1 - 17 shown, the repairable tray includes a panel connection part 11 provided at the bottom of the panel 10, a support top connection part 21 correspondingly provided at the top of the support bar 20. The panel connection part 11 and the support top connection part 21 are connected together to form a preliminary positioning in the vertical direction. A support bottom connection part 22 is provided at the bottom of the support bar 20, and a bottom bar connection part 32 is provided at the top of the support bottom plate 31 of the bottom bar 30. The support bottom connection part 22 is connected to the bottom bar connection part 32. The support bar 20 and the bottom bar 30 are arranged in a vertical staggered manner to form a grid-shaped load-bearing frame, enhancing the overall torsional resistance. Through holes are respectively opened on the panel connection part 11, the support top connection part 21, the support bottom connection part 22 and the bottom bar connection part 32 to form a panel connection lock hole 13, a support connection lock hole 23 and a bottom bar connection lock hole 33. A tray threaded connection structure 60 is embedded in the lock holes. The connecting rod 42 of the automatic lock head 40 is inserted into the lock holes. The threaded structure 43 on the outer side of the connecting rod 42 is screwed with the tray threaded connection structure 60 to vertically fix the panel 10, the support bar 20 and the bottom bar 30. A concave or convex serrated structure 44 is provided at the bottom of the connecting rod 42, which meshes with the tray convex or concave serrated structure 61 in the tray threaded connection structure 60. When rotating and locking, the concave or convex serrated structure 44 forms a mechanical interlock through engagement to prevent the thread from backing off caused by vibration.

[0055] Inside the panel connection part 11, the support top connection part 21, the support bottom connection part 22, and the bottom strip connection part 32, there are spider-web shaped reinforcing ribs, namely the panel web-shaped reinforcing ribs 211, the support web-shaped reinforcing ribs 221, and the bottom strip web-shaped reinforcing ribs 321. By means of a dense cross-grid, local stress is dispersed, and the compressive strength is improved. At the edges of the panel connection part 11, the support top connection part 21, the support bottom connection part 22, and the bottom strip connection part 32 and at the joint position of the support bottom plate 31, a cross-shaped reinforcing rib structure 70 is added to further strengthen the anti-bending ability of the vulnerable areas and prevent cracking at the joints.

[0056] The anti-slip protrusions 12 on the top of the panel 10 increase the friction force during cargo stacking. On the outer sides of the bottoms of the panel connection part 11 and the support top connection part 21, guiding arrows 14 are marked to indicate the direction of lock hole alignment. On the top of the support bottom plate 31 of the bottom strip 30, a guiding arrow 34 is provided, and the inclined surface guides the support bottom connection part 22 of the support strip 20 to slide into the bottom strip connection part 32, reducing the requirements for assembly accuracy.

[0057] Detachable support rods 50 can be installed at the bottom of the panel 10. Both ends of the tubular support body 51 of the support rod 50 are closed by plugs 52, and a pin 53 is provided. The pin 53 is inserted into the reserved hole positions on the side wall of the support strip 20 to form a transverse support network to share the vertical load.

[0058] The vertical staggered arrangement of the support strip 20 and the bottom strip 30 forms a uniformly stressed grid. Combined with the transverse reinforcement of the support rods 50, the dynamic load of the pallet is enhanced.

[0059] As Figure 5 、 Figure 6 and Figure 7 shown, the panel 10 is the top load-bearing component of the repairable pallet, directly contacting the cargo, responsible for evenly distributing the load and providing an anti-slip surface. The panel 10 bears and disperses the weight of the cargo to the support strip 20 and the bottom strip 30. By setting anti-slip protrusions 12 on the surface of the panel 10, the sliding of the cargo is prevented. The panel 10 is quickly locked with the support strip 20 to support disassembly and repair.

[0060] The panel connection part 11 is located at the bottom of the panel 10 and is a structure of multiple protrusions or grooves, which is connected to the support top connection part 21 at the top of the support strip 20. A panel connection lock hole 13 is opened in the center of the panel connection part 11, penetrating the thickness of the panel 10, for inserting an automatic lock head 40 to complete the vertical fixation. At the position of the panel connection part 11 on the top of the panel 10, an array of anti-slip protrusions 12 is provided corresponding to the anti-slip protrusions 12. The anti-slip protrusions 12 are integrally injection-molded with the panel and are made of wear-resistant materials such as high-density polyethylene to extend the service life.

[0061] On the outer bottom of the panel connection part 11 of the guiding arrow 14, a guiding arrow 14 is printed or molded, with the arrow pointing towards the center direction of the lock hole 13, indicating the insertion direction of the support bar 20 during installation, reducing the alignment difficulty and improving the assembly efficiency. Inside the panel connection part 11, a spider-web-like panel mesh reinforcing rib 211 with dense intersections is arranged to enhance the local compressive strength. At the joint where the edge of the panel connection part 11 is joined to the support bottom plate 31, a cross-shaped reinforcing rib 70 is added to further disperse stress and prevent edge cracking.

[0062] As Figure 8 and Figure 9 shown, the support bar 20 is the core load-bearing framework of the repairable tray, located between the panel 10 and the bottom bar 30, responsible for evenly transmitting the cargo load to the bottom bar and dispersing it to the ground. The support bar 20 bears the vertical pressure of the panel 10 and transmits it to the bottom bar 30 through the support bottom connection part 22. The support bar 20 and the bottom bar 30 are vertically staggered to form a grid-like framework, enhancing the overall bending and torsion resistance performance, and quickly locking with the panel 10 and the bottom bar 30 through standardized interfaces, supporting local replacement and repair.

[0063] As Figure 4 and Figure 8 shown, two types of device installation parts 24 with different specifications and sizes are added to the support bar 20 for placing devices such as locators, providing sufficient accommodation space for auxiliary devices.

[0064] The support top connection part 21 is located at the top of the support bar 20 and is connected to the panel connection part 11 of the panel 10; the support bottom connection part 22 is located at the bottom of the support bar 20, and its structure matches the bottom bar connection part 32 of the bottom bar 30 to ensure accurate vertical alignment. A support connection lock hole 23 is opened in the center of the support top connection part 21 and the support bottom connection part 22, penetrating the thickness of the support bar, for inserting an automatic lock head 40 to complete vertical fixation; inside the support top connection part 21 and the support bottom connection part 22, a dense cross-shaped panel mesh reinforcing rib 211 and a support mesh reinforcing rib 221 are arranged to enhance the compressive strength of the connection part. At the joint edge between the support bar 20 and the bottom bar 30, a cross-shaped reinforcing rib 70 is added to disperse stress through radial ribs and prevent cracking at the end of the support bar; the support bar 20 and the bottom bar 30 are arranged vertically and staggered to form a grid-like load-bearing framework, increasing the load capacity limit of the tray.

[0065] As Figure 10 and Figure 11As shown, the bottom bar 30 is the underlying load-bearing structure of the repairable tray, directly contacting the ground and undertaking the final transmission of the load. At the same time, it provides a stable installation base for the support bar 20. The bottom bar 30 disperses the vertical load transmitted by the support bar 20 to the ground, and forms a grid-like framework perpendicular and staggered with the support bar 20 to enhance the overall bending and torsion resistance of the tray. The installation process of the support bar 20 is simplified through the guiding arrow 34 and the bottom bar connection lock hole 33; the support bottom plate 31 is the main part of the bottom bar 30. The guiding arrow 34 is located at the top edge of the support bottom plate 31, used to guide the support bottom connection part 22 of the support bar 20 to slide into the bottom bar connection part 32, reducing the difficulty of assembly alignment; the bottom bar connection part 32 is located at the top of the support bottom plate 31, and is distributed at intervals along the length direction of the bottom bar 30. A bottom bar connection lock hole 33 is opened in the center of the bottom bar connection part 32, passing through the support bottom plate 31 and aligning with the support connection lock hole 23 for the automatic lock head 40 to be inserted and locked; dense and cross-shaped bottom bar mesh reinforcing ribs 321 are arranged inside the bottom bar connection part 32 to enhance the local compressive strength. A cross-shaped reinforcing rib is arranged at the joint edge of the bottom bar connection part 32 and the support bottom plate 31, and the stress is dispersed through the radial ribs to prevent cracking at the joint.

[0066] As Figure 14 shown, in one embodiment, an annular recessed serrated structure 44 is machined at the bottom of the connecting rod 42 at the bottom of the threaded structure 43, and an annular protruding serrated structure 61 is arranged on the inner wall of the tray threaded connection structure 60. The tooth shape is complementary to the recessed serration 44. When in use, when the automatic lock head 40 is tightened, the threaded structure 43 meshes with the tray threaded connection structure 60. When the thread reaches the bottom, the recessed serrated structure 44 and the protruding serrated structure 61 are meshed by rotation to form a mechanical interlock. When the locking head 41 is rotated counterclockwise, a self-locking force is generated on the serrated inclined surface to prevent loosening.

[0067] In another embodiment, an annular protruding serrated structure 44 is machined at the bottom of the connecting rod 42 at the bottom of the threaded structure 43, and an annular recessed serrated structure 61 is arranged on the inner wall of the tray threaded connection structure 60. The tooth shape is complementary to the protruding serrated structure 44. When in use, the threaded structure 43 provides the main locking force. When the automatic lock head 40 is rotated to the bottom, the protruding serration 44 is embedded in the recessed serration 61, and a radial pressing force is generated on the tooth surface. In a vibrating environment, the meshing surface of the serrations resists backward movement through friction, and the anti-loosening effect is remarkable.

[0068] As Figure 15 and Figure 16As shown, the tubular support body 51 of the support rod member 50 is a hollow cylindrical structure. As a transverse reinforcement member, it shares the vertical load and improves the overall torsional resistance of the tray. The outer diameter of the plug 52 matches the inner diameter of the tubular support body 51 and is press-fitted into both ends of the tube body by interference fit. The pin 53 is a cylindrical pin. The diameter of the pin hole reserved on the side wall of the support bar 20 into which the pin 53 is vertically inserted matches the pin, and it is fixed by threads or a circlip to prevent falling off. The support rod member 50 is horizontally erected at the bottom of the panel 10, and the pin 53 is inserted into the side hole of the support bar 20 to form a grid-shaped support network. The gravity of the goods is transmitted from the panel 10 to the support rod member 50, and then shared by the support bar 20 on both sides, reducing the single-point stress concentration. The pin 53 can be manually pulled out for easy maintenance or adjustment of the tray size. The automatic lock head 40 is inserted into the panel connection lock hole 13, the support connection lock hole 23, and the bottom bar connection lock hole 33. The threaded structure 43 is screwed with the tray threaded connection structure 60 to provide an axial pre-tightening force. When the thread is screwed to the bottom, the recessed serrations 44 engage with the protruding serrations 61, and the rotational torque generates a radial pressing force on the tooth surface to form a mechanical interlock to resist the backlash caused by vibration.

[0069] As Figure 17 shown, the repairable trays can be stacked together during recycling, reducing the space occupied by the repairable trays. Anti-slip protrusions 12 are provided on the top of the panel 10 of the lower tray, which cooperate with the guiding arrow 34 of the bottom bar 30 of the upper tray. The inclined surface of the guiding arrow 34 guides the bottom bar connection part 32 of the bottom bar 30 of the upper tray to slide into the panel connection part 11 of the panel 10 of the lower tray to achieve quick alignment. Guide arrows 14 are marked on the sides of the panel 10 and the bottom bar 30 to indicate the stacking direction of the upper and lower trays, ensuring that the vertical staggered layout of the support bar 20 and the bottom bar 30 remains aligned during multi-layer stacking.

[0070] The panel connection lock holes 13, the support connection lock holes 23, and the bottom bar connection lock holes 33 of each layer of the tray are aligned vertically during stacking. The gravity of the goods on the upper tray is transmitted to the bottom bar 30 of the upper tray, and then to the panel 10, the support bar 20, and the bottom bar 30 of the lower tray, and finally transmitted to the ground. The panel mesh reinforcing ribs 211, the support mesh reinforcing ribs 221, and the bottom bar mesh reinforcing ribs 321 and the cross-shaped reinforcing ribs 70 at the edge disperse the stress to ensure uniform load-bearing of each layer of the tray. When stacking, the support rod member 50 is inserted into the side holes of the support bar 20 of each layer of the tray to form a cross-layer transverse support network to prevent lateral tilt. The recessed or protruding serration structures 44 at each locking point match the protruding or recessed serration structures 61 of the tray, and are engaged by rotation to resist the loosening of the connection caused by stacking vibration and ensure the stability of the locking force.

[0071] When stacking, first align the guiding arrow 34 of the bottom strip 30 of the upper tray with the anti-slip protrusion 12 of the lower tray panel 10. The anti-slip protrusion 12 of the panel 10 is positioned and matched with the reinforcing rib at the bottom of the bottom strip 30, and they are mutually locked to achieve safe and efficient multi-layer stacking, which is applicable to high-density warehousing and logistics transportation scenarios, making the best use of vertical space and ensuring stability.

[0072] Working principle: The repairable tray realizes high-efficiency load-bearing and anti-loosening through the modular snap connection of the panel 10, the support strip 20, and the bottom strip 30 and the screw-sawtooth double locking mechanism of the automatic lock head 40. Among them, the panel connection part 11 at the bottom of the panel 10 is snap-fitted with the support top connection part 21 at the top of the support strip 20 in a matching shape. The support bottom connection part 22 at the bottom of the support strip 20 slides into the bottom strip connection part 32 along the guiding arrow 34 of the bottom strip 30 to form a preliminary vertical positioning; the panel connection lock hole 13, the support connection lock hole 23, and the bottom strip connection lock hole 33 are embedded with the tray threaded connection structure 60. The connecting rod 42 of the automatic lock head 40 is inserted into the lock hole, and the threaded structure 43 on its outer side is screwed with the threaded connection structure 60 to provide an axial pre-tightening force. At the same time, the concave or convex sawtooth structure 44 at the bottom of the connecting rod 42 is rotationally engaged with the complementary tray convex or concave sawtooth structure 61 in the tray threaded connection structure 60 to form a mechanical interlock, using the self-locking of the trapezoidal or triangular tooth-shaped inclined plane to resist the thread back-off caused by vibration; the panel mesh reinforcing ribs 211, the support mesh reinforcing ribs 221, and the bottom strip mesh reinforcing ribs 321 inside the panel connection part 11, the support top connection part 21, the support bottom connection part 22, and the bottom strip connection part 32 and the cross-shaped reinforcing ribs 70 at the edge disperse the stress concentration of the tray and improve the compressive and flexural strength; the anti-slip protrusions 12 on the top of the panel 10 increase the friction of the goods, and the guiding arrows 14 on the outer side of the bottom are used to guide the quick alignment with the guiding arrow 34 of the bottom strip 30; the detachable support rod member 50, the tubular support body 51, the plug 52, and the pin 53 form a transverse reinforcement network by inserting the pin 53 into the side hole of the support strip 20. Combining with the vertical staggered layout of the support strip 20 and the bottom strip 30, a grid-shaped load-bearing framework is formed, and the dynamic load is improved. In summary, through modular connection, double locking, structural strengthening, and guiding design, the coordinated optimization of high load-bearing, anti-vibration, quick disassembly and assembly, and low-cost maintenance is achieved.

[0073] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
