The beneficial effect of the present invention is that during the assembly process of the logistics pallet, the assembly and fixing process of the pallet, the bottom frame and the pad is completed through the cooperation of the locking nail and the locking buckle. Since the locking nail and the locking buckle do not need thread cooperation, only the The nail tip of the lock nail is aligned with the center of the nail barrel of the lock and an external axial force is applied. Since the lock hook on the lock is elastically set according to the selection of the material, the nail tip of the nail is inserted into the lock barrel during the insertion process. Extend the lock hook outward until the lock hook slides to the hook groove of the lock nail. Under the action of elastic force, the lock hook returns inward and hooks in the hook groove to complete the positioning and fixing process.

In addition, in order to adapt to the installation range of multiple thicknesses, there are multiple hook grooves near the nail tip, so the lock hooks on the lock buckle are sequentially hooked in different under the axial force during the installation process. Hook groove, and finally stay in the appropriate hook groove to complete the fastening effect.

In addition, the lock of the lock can also be provided with a multi-layer hook structure, so in the compression installation of the lock nail and the lock, the lock can be hooked and locked by itself according to the relative position of the lock hook and the hook groove.

Since the logistics pallet is used for loading goods, the flatness of the top of the pallet and the bottom of the bottom frame are required. Therefore, the second opening and the third opening are respectively set at the end away from the pad as a counterbore; the first nail cap And the second nail cap is provided with a countersunk head, and lies in the sink of the second opening and the third opening respectively. Therefore, the first nail cap and the second nail cap are prevented from rising above the surface of the tray and the bottom frame.

In the above setting, in order to solve the problem of disassembling the logistics tray, since the lock nails and the locks are all docked and locked in the first opening, the second opening and the third opening, it is difficult to lock the lock. Hook to unlock. To this end, the first nail cap of the lock nail is set as an detachable structure, which is connected to the nail tip by a screw. Therefore, in the disassembly of the logistics tray, the first nail cap is removed by a screwdriver. After being restrained, the lock buckle can be pulled out of the third opening. During the pull-out process of the lock buckle, the hook nails are brought out together, thereby solving the problem of disassembling the logistics tray. The head of the first nail cap may be provided with a cross mouth, a flat mouth, an inner hexagonal mouth, and an inner hexagonal mouth.

In the above setting, in order to solve the problem of disassembly failure caused by the rotation of the nail tip and the first nail cap during the disassembly of the first nail cap, a hexagonal groove was set up at the nail tip portion without affecting the head of the locking hook. In addition, the hexagonal groove can be replaced by a hexagonal groove, a cross groove, and a flat groove. The definition of the specific shape is determined by the common tool characteristics. The so-called tool characteristics include the diameter of the tool shaft. , And length, so that the tool can smoothly pass through the hollow part of the lock and contact with the groove of the nail tip.

In the above setting, in order to compensate for the insufficient shear force of the lock nail and the lock, the large head portion of the buffer block is embedded in the first recess of the cushion block, and only the small head portion is exposed, so that the upper and lower ends are installed. The cushion block of the buffer block realizes the mortise lock structure. The second recesses on the supporting plate and the connecting beam are respectively matched with the small heads of the buffer blocks at the upper and lower ends of the cushion block. Because the side walls of the large head and the small head of the buffer block are tightly matched with the side walls of the first recess and the second recess, respectively, the lateral gap between the pallet and the pad, and between the bottom frame and the pad is eliminated. So as to strengthen the shearing force.

The buffer block may be provided in a solid or hollow manner. When it is solidly set, it can achieve the effect of shearing force buffering through the toughness and elasticity of its material; when it is hollowly set, when subjected to shearing stress, the buffering block can buffer the impact force through structural deformation.

In the above setting, in order to prevent the load-bearing logistics pallet from crushing the pad during the moving process. The connection between two adjacent connecting beams and the central position of a single connecting beam with the cushion block can better play the reinforcing effect of the connecting beam.

In the above setting, in order to avoid the damage caused by the collision between the connecting beam and the fork wall, the guide renting of the fork wall is realized by the oblique chamfer to prevent the hard collision between the fork wall and the outer side wall of the connecting beam.

In addition, the two vertical edges on the outside of the pad can also be used as a guide for the fork wall of the forklift, so it can also be set for oblique chamfering.

The upper and lower two walls of the first hemming are attached to the upper and lower sides of the pallet, and a gap is left between the outer side wall of the pallet and the inner side of the first hemming. This gap is used for the first hemming collision deformation zone. After the logistics pallet is impacted by an external force during transportation, the first hemming buffers the impact force through deformation, thereby protecting the pallet from being damaged by the impact force. The first hemming is designed to be replaceable, so when the first hemming is completely damaged, the service life of the logistics tray can be extended by replacing the first hemming with a new one. At the same time, you can control the cushioning strength by setting the material of the first hemming, such as stainless steel, rubber, and review materials.

Another second hemming is used to protect the inclined chamfer of the connecting beam to prevent the connecting beam from being damaged by the crushing friction of the forklift fork wall. At the same time, the second hemming of the metal or hard material can smooth the forklift fork wall. The guiding function is performed, so that the fork wall can be smoothly inserted into the gap of the logistics tray.

A concave surface is provided at the above-mentioned matching place of the first covering edge and the supporting plate and the matching place of the second covering edge and the connecting beam, and the depth of the small concave surface is consistent with the thickness of the corresponding first covering edge and the second covering edge, respectively. Therefore, when the supporting plate and the connecting beam are installed with the first and second hemmings respectively, the outer surfaces of the first and second hemming will not be higher than the surface of the supporting plate and the connecting beam, and the supporting plate and the connecting beam will be The connecting beam always has a flat external structure.

In order to install the first hemming and the second hemming more quickly, during the manufacturing process of the production line, the first hemming is first positioned around the pallet, and the teeth are punched by the punch of the stamping machine. The center of the plate is punched. The diameter of the punch is equal to or slightly smaller than the diameter of the crank hole, and the front end of the punch is set in a conical or spherical shape. During the punching process of the punch, it first contacts the head of the canine in the crank. The canine is curled and deformed downward, and rolled into the through-hole of the pallet. As the punch descends, the amplitude of each canine in the dental plate is increased until the tip of the head of the canine penetrates the penetration of the pallet. In the inner side wall of the hole, the first edging is firmly fixed on the periphery of the supporting plate with the cooperation of the canine teeth and the through hole. In the same way, the second hemming and the connecting beam are also fixed by stamping, thereby eliminating the tedious steps of screw installation and saving productivity investment.

In addition, when the supporting plate, the spacer and the connecting beam are made of wooden material, steel nail connections can be performed on the upper side of the supporting plate and the corresponding side of the spacer on the bottom side of the connecting beam. The steel nail is used to reinforce the cooperation of the lock nail and the lock buckle, thereby greatly improving the installation strength of the logistics pallet.
