Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, a core skeleton for casting sand box, comprising a body 1, wherein a fixing component 2 is arranged on the body 1, the fixing component 2 comprises a fixing block 21, a rotary drum 22 is fixedly connected on the fixing block 21, the rotary drum 22 is rotationally connected with the body 1, a fixing hole 24 is arranged on the fixing block 21, a fixing rod 23 is arranged in the rotary drum 22, the fixing rod 23 is a bolt, the fixing hole 24 is a threaded hole, threads are arranged in the rotary drum 22, the number of the threads of the rotary drum 22 is five at most, when the rib frames are stored after being manufactured by a production line, an operator places one rib frame on the ground, then places the other rib frame on the top of the previous rib frame, simultaneously turns the fixing block 21 on four corners where the two rib frames are contacted, and when turning, the fixing block 21 is turned by rotating the fixing rod 23, taking one angle of two rib skeletons as an example, an operator turns over two fixing blocks 21 to enable one ends of the upper fixing block 21 and the lower fixing block 21 to face the outer side of the body 1, the fixing blocks 21 at the other three angles are similar, finally the operator inserts a fixing rod 23 into a fixing hole 24 of the two fixing blocks 21 to finish fixing, the two rib skeletons are fixed together, displacement falling damage caused by external touch is avoided, the fixing rod 23 is a bolt and can be screwed into the rotary drum 22 to form a whole with the rotary drum 22, the turnover of the fixing blocks 21 is convenient to control, meanwhile, the fixing rod 23 can be screwed out from the rotary drum 22, when the fixing rod 23 is screwed out, the operator only needs to stop fingers in the turnover direction of the fixing block 21 to be driven by the operator, the fixing rod 23 is prevented from driving the fixing block 21 to rotate when the fixing rod 23 is screwed out, the fixing block 21 cannot be screwed out, and the rotation is prevented when the fixing rod is screwed out is similar, the operator blocks the fixed rod 23 to drive the fixed block 21 to rotate with fingers to prevent the fixed block 21 from rotating, finally the rotated fixed rod 23 is inserted into the fixed holes 24 of the outer parts of the two fixed blocks 21 positioned on the body 1, the two rib frames are screwed and fixed, the two rib frames are fixed together in real time and cannot slide relatively, the safety accident caused by collapse due to external interference is avoided, meanwhile, the operation is repeated, a plurality of rib frames are stacked and fixed together, the occupied area is saved, and the operation is simple and convenient.
