Embodiment Construction

[0017] like Figure 1-4 The shown multi-dial combination lock cylinder includes a first dial mechanism, a second dial mechanism and a third dial mechanism that are set through the central axis 1, and a compression spring 2 is pressed on the bottom of the first dial mechanism . Wherein, the first dial mechanism includes a first telescopic upper shaft 32, a first telescopic lower shaft 31 and a first driven cam 33, ten first grooves 36 are arranged on the bottom surface of the first telescopic lower shaft 31 along the circumferential direction, On the upper end surface of the first driven cam 33, ten first convex points 35 are arranged along the circumferential direction; The shaft 31 and the first driven cam 33 are sleeved on the central shaft 1 sequentially from top to bottom. The upper end of the compression spring 2 is located in the sinking groove 38 of the first driven cam 33. The shafts 31 are engaged with each other by convex-concave gaps, and the ten first grooves 36 ...

Abstract

The invention discloses a coded lock cylinder with multiple drive plates, which at least comprises a first drive plate mechanism and a second drive plate mechanism. A center shaft penetrates through the first drive plate mechanism and the second drive plate mechanism, the second drive plate mechanism is sleeved outside the first drive plate mechanism in a stacked manner, a pressure spring is disposed at the bottom of the first drive plate mechanism, a digital drive plate is combined with a telescopic shaft consisting of a lower telescopic shaft and an upper telescopic shaft, the digital drive plate with the larger volume is placed on the upper portion of the center shaft in a stacked manner, a plurality of driven cams with small volumes are placed on the middle lower portion of the center shaft in a stacked manner, the pressure spring is used for providing friction force for the driven cams simultaneously, during usage, the lower telescopic shaft and the upper telescopic shaft can axially move, and radial rotation is not affected. The coded lock cylinder is small in volume, simple in structure, simple and convenient in operation and convenient in locking and unlocking, and has at least two codes and many code combinations, the quantity of the codes is high, and safety is also high.

Description

technical field [0001] The invention belongs to the technical field of locks, in particular to a multi-dial combination lock cylinder. Background technique [0002] Combination locks with traditional structures include the following two types: one is that one combination disk controls multiple sets of internal turntables at the same time, resulting in a complicated process of opening and closing the lock; the other is that multiple combination disks are arranged in sequence with the corresponding internal turntables, thereby increasing The volume of the combination lock is increased. Therefore, there is a lack of a combination lock product that can place a plurality of combination dials on the same side in the market, and has the advantages of opening and closing the lock and resetting the combination. Contents of the invention [0003] The object of the present invention is to provide a multi-dial combination lock cylinder with convenient locking and unlocking, large num...
