Problems solved by technology

However, due to the asymmetrical elastic cantilever of the password wheel assembly of this structure, the force during forward and reverse rotation is inconsistent, so the force of forward and reverse rotation is different, and the user experience is not perfect; in addition, the structure of the elastic cantilever single-ended connection, in The connection is prone to mechanical fatigue, which affects the service life
In addition, in the existing cipher wheel assembly, the locating wheel usually forms linkage by arranging arc-shaped lugs on the peripheral edge to cooperate with the locating groove on the inner hole wall of the cipher wheel. Since the locating wheel is generally made of sheet metal, after Long-term use will increase the positioning gap, resulting in inaccurate positioning

specific Embodiment

[0010] Specific embodiment: the code wheel assembly includes an annular code wheel 1 , an annular positioning wheel 2 , and an elastic wheel 3 . Said annular positioning wheel 2 and elastic wheel 3 inner hole diameters are matched with the combination lock tube clearance, usually because the cross-sectional outline of the combination lock tube is not a complete circle, so the cross section of the elastic wheel 3 central through hole and the combination lock tube The outer contours are the same and clearance fit can achieve circumferential positioning connection. Such as Figure 1-3 As shown, the inner hole of the annular positioning wheel 2 and the elastic wheel 3 is provided with a gap matching with the protrusion of the combination lock plug, and the inner wall of the annular combination wheel 1 is evenly provided with several positioning grooves 101, and the end surface of the inner cavity is provided with The protruding linkage block 102, the linkage block 102 is preferab...

Abstract

The invention relates to a password wheel assembly of a password lock. The password wheel assembly comprises an annular password wheel, an annular locating wheel and an elastic wheel, a plurality of locating grooves are evenly formed in the inner wall of the annular password wheel, locating protrusions are arranged on the elastic wheel, notches are formed in the periphery of the elastic wheel along the arc, strip-shaped elastic strips are integrally arranged at the openings of the peripheries of the notches, the locating protrusions are arranged between the elastic strips, and the elastic strips on the two sides of the locating protrusions are symmetrically arranged. Due to the fact that the locating protrusions are arranged between the elastic strips, the elastic strips on the two sides of the locating protrusions are symmetrically arranged, and the locating protrusions are evenly stressed on the peripheries, when the annular password wheel is forwards and reversely rotated, feelings are the same, meanwhile, the two ends of the elastic strips are integrally connected to the elastic wheel, and the password wheel assembly is firm and durable.

Description

technical field [0001] The invention relates to a combination lock component, in particular to a combination wheel assembly of the combination lock. Background technique [0002] Traditional cipher wheel assembly is made up of annular cipher wheel, annular location wheel, annular reed seat wheel, reed. The reed is stuck in the slot on the reed seat wheel, the positioning wheel and the reed seat wheel are stacked and set in the code wheel and then set on the code lock tube together, wherein the positioning wheel and the code wheel are circumferentially positioned and connected. The reed seat wheel is connected with the password lock tube in the circumferential direction. The reed seat wheel and the inner ring of the positioning wheel are provided with a gap matching the protrusion of the code lock plug. When all the code wheels are rotated until the gap is in a straight line and consistent with the slot position When the combination lock plug is pulled out from the combinati...
