Abstract
The utility model discloses a spring turnover pin which belongs to the field of architectural formwork component. The utility model is characterized in that a pin base is a cylinder provided with a screw hole in the bottom center, the end of a screw thread section passes through the central hole of the pin base and is pressed at the pin base by a screw nut. The other section is a smooth section with a hollow chamber, one side of the smooth section is provided with a long hole, and the blade is dogged at the long hole after the blade turnover and a spring is arranged in the hollow chamber. The utility model has the advantages of that no directions have to be classified during operation, a diagonal draw rod can be easily connected, the turnover lock blade can be self-locked through the spring to prevent the diagonal draw rod from releasing, and the turnover lock blade can be easily extracted by slightly pressing the blade when disassembling. Further, the utility model has convenient usage and safety and reliability.
Description
Technical field
The utility model belongs to the construction formwork components range, particularly a kind of spring upset pin.
Background technology:
The most traditional fixing method of the drag link of original construction formwork support, scaffold and diagonal member is to bind with galvanized wire, original wide model uses clip to lock with bolt, the very trouble that operates, and diagonal member is loosening easily, cause and do over again, increase working strength of workers and incur loss through delay the duration.
Summary of the invention:
The purpose of this utility model provides a kind of spring upset pin, it is characterized in that, the key seat 5 of described spring upset pin has the cylinder of screw hole for end central authorities, screw rod 8 middle parts are provided with hexagon block 3, one end is a thread segment 9, pass key seat 5 medium pores after, be pressed on the key seat 5 by nut 4; Another section is the smooth section that cavity is arranged, and has slotted hole 7 in a side of smooth section, and blade 1 its blade hook 6 of upset back is stuck in the slotted hole 7, places spring 2 in cavity.
The beneficial effects of the utility model need not the branch direction when being operation, can be connected with diagonal member easily, and the tumble lock blade pass is crossed the spring automatic locking, prevents that diagonal member from getting loose, and the light blade of pressing can take out during dismounting, and the utility model is esy to use, safe and reliable.
