Description

Technical Field

[0001] The utility model belongs to the technical field of pallet detection, and in particular relates to a strength detection device for a pallet. Background Art

[0002] Pallets are the medium that transforms static goods into dynamic goods, a cargo platform, and an active platform, or a movable ground. Even if the goods are placed on the ground and lose their flexibility, they will immediately become active and become flexible mobile goods once they are loaded on the pallet, because the goods loaded on the pallet are ready to be put into motion at any time.

[0003] For example, a Chinese patent with a publication number of CN220356827U discloses a strength detection tool for a pallet, including a device body and a connecting component arranged on the device body, the connecting component includes an adjusting part arranged in the middle section of the device body, the adjusting part is connected to a limiting part, and detection parts are arranged on both sides of the device body, and the spacing of the support base plates is adjusted by sliding the support base plate left and right, and the width of the support base can be adjusted according to different structures of the receiving plate; the push-pull force gauge fixedly connected to the front side of the rack plate moves, and the push-pull force rod arranged at the bottom of the push-pull force gauge moves accordingly, and the strength of the object to be tested can be detected. Through the transmission of the push-pull force rod, the force borne by the object to be tested is fed back to the display screen arranged on the front side of the push-pull force gauge for reading. The push-pull force gauge can effectively sense the real-time strength value of the pallet.

[0004] When the existing strength detection device for a pallet is used, the pallet is easily offset by force, resulting in a large error in the strength detection result of the pallet. In view of this, we propose a strength detection device for a pallet. Utility Model Content
