Technical Field

[0001] This utility model relates to the field of wooden pallet technology, specifically a wooden pallet with a reinforced foot post connection structure. Background Technology

[0002] In the fields of containerization, stacking, handling and transportation, wooden pallets are logistics carriers made from logs or plywood through processes such as drying, shaping, cutting and planing. They are widely used horizontal platform devices in logistics and warehousing. At the same time, nine wooden posts are usually fixedly installed on the back of the wooden pallet, distributed in the middle of the four sides and four corners of the wooden pallet, forming a stable support structure, making the wooden pallet more stable when carrying goods and less prone to tilting or tipping over.

[0003] Currently, the nine wooden legs on the back of existing wooden pallets are mainly secured with threaded nails / iron nails during long-term use. However, considering that wooden pallets are under dynamic loads and frequent operation during transportation, the wooden legs may easily loosen from the load-bearing panel and may detach due to impact, leading to local instability in the pallet's support and affecting its continued normal use. Therefore, a wooden pallet with a reinforced leg connection structure is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wooden pallet with a reinforced leg connection structure to solve the problem mentioned in the background art that when existing wooden pallets are used with multiple legs installed, the legs are prone to loosening of the connection with the load-bearing panel and are prone to loosening under impact.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wooden pallet with a reinforced leg connection structure includes a support plate, a leg body attached to the bottom of the support plate, a cross-shaped groove on the bottom surface of the leg body, a central chuck in the middle of the cross-shaped groove, a reinforcing strip fixedly connected to the outside of the central chuck, an opening on the surface of the reinforcing strip, a reinforcing aluminum tube attached to the top of the reinforcing strip covering the opening, a limiting stud fixedly connected to the top of the reinforcing aluminum tube, a pre-embedded sleeve fitted inside a reserved circular groove on the bottom surface of the support plate, a limiting pin inserted into the middle of the top of the pre-embedded sleeve, and a limiting rotating rod extending into the opening fixedly connected to the bottom of the reinforcing aluminum tube.

[0007] Preferably, the top of the bearing plate is provided with a groove, and a plurality of the grooves are arranged in an equidistant structure along the horizontal direction.

[0008] Preferably, the support column bodies are arranged in three rows of three, and a base plate is glued to the bottom of each support column body. There are three base plates in total, and the base plates and the supporting plate are arranged in parallel.

[0009] Preferably, the reinforcing strips fit snugly into the interior of the cross-shaped slots, and the four reinforcing strips and the central chuck are connected to form a cross-shaped structure.

[0010] Preferably, the central chuck has a central hole in the middle, and the inner side of the foot column body has a fixing hole in the middle, with the fixing hole and the central hole positioned vertically opposite each other.

[0011] Preferably, the reinforcing aluminum tube passes through a slot opened near the edge of the foot post body, and the four reinforcing aluminum tubes are arranged in a ring array structure along the center point of the central chuck. The outer diameter of the reinforcing aluminum tube is smaller than the length of the rotating rod. The reinforcing aluminum tube and the limiting stud are coaxially arranged, and the limiting stud is threadedly connected to the pre-embedded ferrule.

[0012] Preferably, the bottom of the pre-embedded sleeve and the bottom of the bearing plate are on the same horizontal line, and the bearing plate and the limiting pin are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the inclusion of reinforcing clips, a central chuck, a central hole, a reinforcing aluminum tube, a pre-embedded sleeve, a limiting pin, a limiting stud, a limiting rotating rod, and a pre-embedded sleeve facilitates the installation of the wooden pallet's legs during manufacturing. With the cross-shaped slot and pre-reserved slot, the pre-positioning structure, consisting of the reinforcing clips, central chuck, central hole, reinforcing aluminum tube, pre-embedded sleeve, limiting pin, limiting stud, and limiting rotating rod, along with the pre-embedded sleeve, pre-positions the individual leg body. This design, without affecting the normal installation of the individual leg body, also strengthens the connection between the leg body and the load-bearing plate after installation, increasing the tightness of the connection and preventing loosening or detachment of the leg body, thus avoiding localized instability in the pallet's support.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A wooden pallet with a reinforced leg connection structure includes a support plate 1, a leg body 2 attached to the bottom of the support plate 1, a cross groove 13 on the bottom surface of the leg body 2, a central chuck 5 fitted in the middle of the cross groove 13, a reinforcing strip 4 fixedly connected to the outside of the central chuck 5, an opening 14 on the surface of the reinforcing strip 4, a reinforcing aluminum tube 7 attached to the top of the reinforcing strip 4 covering the opening 14, a limiting stud 10 fixedly connected to the top of the reinforcing aluminum tube 7, a pre-embedded sleeve 8 fitted inside a reserved circular groove on the bottom surface of the support plate 1, a limiting pin 9 inserted into the middle of the top of the pre-embedded sleeve 8, and a limiting rotating rod 11 extending into the opening 14 fixedly connected to the bottom of the reinforcing aluminum tube 7.

[0024] like Figure 1 As shown, the top of the support plate 1 has a groove 12. Several grooves 12 are arranged at equal intervals along the horizontal direction. The arrangement of multiple grooves 12 forms an anti-slip structure on the upper surface of the support plate 1, increasing the anti-slip ability when the load is placed on the support plate 1 for transportation. The leg body 2 is arranged in three rows of three. The bottom of the leg body 2 is glued with a base plate 3. There are three base plates 3 in total. The base plates 3 are arranged parallel to the support plate 1. The arrangement of the base plates 3 connecting the three leg bodies 2 at the same time can make the connection between the three leg bodies 2 tighter.

[0025] like Figure 1 and Figure 2 As shown, the reinforcing clips 4 fit into the interior of the cross-shaped slot 13. The four reinforcing clips 4 and the central chuck 5 are connected to form a cross-shaped structure. This structure facilitates the precise insertion of multiple clips and the central chuck 5 into the interior of the cross-shaped slot 13.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a central hole 6 is provided in the center of the central chuck 5, and a fixing through hole 15 is provided in the center of the inner side of the foot column body 2. The fixing through hole 15 and the central hole 6 are positioned vertically opposite each other. The reserved setting of the fixing through hole 15 facilitates the fixed connection of the foot column body 2 and the bearing plate 1 by using long screws. The reinforcing aluminum tube 7 passes through the slot opened near the edge of the foot column body 2. The four reinforcing aluminum tubes 7 are arranged in a ring array structure along the center point of the central chuck 5. The outer diameter of the reinforcing aluminum tube 7 is smaller than the length of the rotating rod. The reinforcing aluminum tube 7 and the limiting stud 10 are coaxially set. The limiting stud 10 is threadedly connected to the pre-embedded sleeve 8. The reserved slot on the edge of the foot column body 2 facilitates the combination connection of the foot column body 2 with the pre-positioned part. The bottom of the pre-embedded sleeve 8 and the bottom of the bearing plate 1 are on the same horizontal line. The bearing plate 1 is threadedly connected to the limiting pin 9. The limiting pin 9 serves to fix the pre-embedded sleeve 8 into the circular groove structure at the bottom of the bearing plate 1.

[0027] Workflow: In this utility model, the transport vehicle needs to be used in conjunction with a forklift. Before use, during manufacturing, the carrying plate 1 is placed at an angle onto a similarly angled support platform. Since the pre-embedded sleeves 8 are pre-connected to the carrying plate 1 via limiting pins 9, the multiple reinforcing strips 4 and the central chuck 5 are inserted into the cross-shaped slot 13, allowing the reinforcing aluminum tube 7 to be inserted into the pre-reserved slot at the edge of the leg body 2. The limiting studs 10 extend upwards from the slot. Then, under the limiting action of the limiting pins 9, the structure of the pre-embedded sleeves 8 is aligned. After the leg body 2 is fitted into the pre-reserved installation area of ​​the carrying plate 1, the reinforcing aluminum tube 7 and the limiting studs 10 are adjusted by rotating the lever, thereby connecting the four limiting studs 10 and the four pre-embedded sleeves 8 together. This process is repeated for any necessary reinforcement. The individual leg body 2 is pre-positioned and connected to the back of the support plate 1. Then, it is fixed to the support plate 1 by using long screws that pass through the center hole 6 and the fixing through hole 15. At the same time, the pre-positioning structure composed of reinforcing clip 4, center chuck 5, center hole 6, reinforcing aluminum tube 7, pre-embedded sleeve 8, limiting pin 9, limiting stud 10 and limiting rotating rod 11 can strengthen the connection structure after the individual leg body 2 is installed without affecting the normal assembly and installation of the individual leg body 2, and increase the tightness of the connection between the individual leg body 2 and the support plate 1. Then, in the same way, three rows of nine leg bodies 2 are fixed to the back of the support plate 1 in sequence. Finally, the bottom plate 3 is glued to the bottom surface of one row of leg bodies 2 for transition and fixation. The manufacturing operation of a single wooden pallet is then completed.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
