Embedded multidirectional frame connection node for packing case

Abstract

The invention relates to an embedded multidirectional frame connection node for a packing case. The embedded multidirectional frame connection node for the packing case structurally comprises an embedded steel plate base, a multidirectional steel plate connection arm A, a multidirectional steel plate connection arm B and a multidirectional steel plate connection arm C, wherein the embedded steel plate base is hinged with the multidirectional steel plate connection arm A and the multidirectional steel plate connection arm C, and the multidirectional steel plate connection arm C is also hinged with the multidirectional steel plate connection arm B. The embedded multidirectional frame connection node for the packing case has the advantages that firstly the node is embedded into a tray of the packing case and is connected with an upright or an inclined strut, so that the packing case is smooth in the outer surface and is convenient to stack, load and unload and transport; secondly, the tray, the upright and the inclined strut are connected by an adjustable steering connection arm, so that the node has generality and is convenient to produce in a standardization manner; thirdly, the multidirectional connection arm has directional adjustable characteristics, and is low in demand on machining precision of a packing case member, and convenient to install and recover; and fourthly, the adjustable multidirectional connection node adopts a steel plate for connecting a wood member; the strength of the node of a heavy packing case is greatly enhanced, and the security and reliability of the packing case are enhanced.

Description

technical field [0001] The invention relates to a connection node of a large-scale heavy-duty electromechanical product packaging box, that is, a connection node of an embedded multi-directional frame packaging box, and belongs to the field of engineering technology. Background technique [0002] In the packaging of heavy mechanical and electrical products in my country, wood packaging accounts for about 80%, and consumes more than 10 million cubic meters of wood every year, accounting for about 1 / 6 of my country's commercial wood production, and most of them are high-quality wood. Due to the imperfect packing box design theory and backward design methods, overpacking (excessive packaging strength and rigidity) or underpackaging (insufficient packing box rigidity) caused by improper packing box design is very common, resulting in serious waste of resources or significant economic loss. According to data released by the Ministry of Commerce, my country’s export commodities l...

Problems solved by technology

[0004] The structural connection of traditional large-scale mechanical and electrical product wooden packaging boxes in my country is mostly connected by nails. This connection method has several fatal weaknesses: (1) The joint connection strength is small. During transportation, the packaging box is easily damaged due to constant shock and vibration. ; (2) The components of the nail connection node are staggered and overlapped, and the node structure is complex, which is not conducive to handling and stacking; (3) The nail connection will be loose due to the creep of the material and the vibration of the load; (4) The nail connection node has poor versatility and is not suitable Standardized production, difficult material recycling, resulting in a lot of waste of wood resources
