Anti-clearance structure for shifting peach of square core of lock body
By designing large torsion springs, upper paddles, lower paddles and paddle spring components in the lock body, the square core is scattered and tightened, which solves the problem of poor door opening feel caused by the gap between the square core and the paddle in the lock body, achieving a gapless fit and a better feel experience.

AI Technical Summary
Technical Problem
In the existing lock body slitting structure, there is a certain gap between the square core and slitting, which leads to a certain angle of idling when opening the door, which makes the hand feel poor.
Method used
A lock-body square core slitting and slitting gap prevention structure is designed. By setting a large torsion spring, upper paddle, lower paddle and slitting spring assembly in the box, the lower paddle and upper paddle rotate clockwise and counterclockwise through the spring action, and the square core is slid and slid, thereby eliminating the gap between the square core and slitting.
Benefits of technology
The square core and the peach are fitted without gap, eliminating the idle problem when holding down the pressure and improving the door opening feel.

Abstract
The invention provides a lock body square core shifting block anti-clearance structure which comprises a box body, an upper shifting piece, a lower shifting piece, a shifting piece spring assembly and a large torsional spring, a handle shifting block hole is formed in the box body, and the large torsional spring is arranged on the periphery of the handle shifting block hole; an upper plectrum hole is formed in the middle of the upper plectrum, a lower plectrum hole is formed in the middle of the lower plectrum, the upper plectrum and the lower plectrum are sequentially stacked on the handle plectrum hole, and the upper plectrum hole, the lower plectrum hole and the handle plectrum hole are correspondingly formed; the shifting piece spring assembly and the large torsional spring interact on the upper shifting piece and the lower shifting piece, the lower shifting piece is subjected to clockwise elastic force, the upper shifting piece is subjected to anticlockwise elastic force, the lower shifting piece rotates by a preset angle clockwise, and the upper shifting piece rotates by a preset angle anticlockwise, so that a lower shifting piece hole and an upper shifting piece hole are staggered, and the square core is clamped. And a gap between the square core and the shifting peach is eliminated. By utilizing the invention, the problem of poor hand feeling caused by idling door opening during door opening due to a certain gap between the square core and the shifting peach can be solved.
