Embodiment 1

[0037] Refer to attached figure 1 : A keyless blind opening mechanical combination lock, comprising a vertical plate 1, a bottom plate 2, a turntable 6, an insertion disc 7 and a runner shaft 5, the vertical plate 1 and the bottom plate 2 are vertically connected to form a mounting bracket, and the turntable 6 and the insertion disc 7 are coaxial Set on the runner shaft 5, the runner shaft 5 is horizontally rotated and installed on the vertical board 1, specifically, one end of the runner shaft 5 passes through the vertical board 1, and the other end is fixedly connected to the backboard 14; one end of the runner shaft 5 passes through the vertical board 1 and The end rotating sleeve is equipped with a password runner 3; the inner end surface of the turntable 6 close to the plug-in disk 7 is provided with a horizontally arranged latch 12, and the plug-in disk 7 is correspondingly provided with a plurality of forward slots 703 and reverse slots 701; A positioning board 13 is pr...

Embodiment 2

[0057]The plug-in disc 7 can be provided with multiple groups of forward slots 703 and reverse slots 701 coaxially set inside and outside, and the outer peripheral end surface of the turntable 6 is correspondingly provided with multi-turn marking slots 601 . The inside of the turntable rib 603 is provided with a cavity, and the two sides of the turntable rib 603 are provided with adjustment slots 602 that allow the bolt 12 to move radially. The adjustment mechanism is a rack and pinion mechanism 8, including a gear 802 installed on the runner shaft 5 and a rack 801 vertically placed in the inner cavity of the turntable rib 603. The upper part of the rack 801 is fixedly connected to the pin 12, and the lower part engages the gear 802.

[0058] The runner shaft 5 is a hollow shaft, and the inner sleeve bolt of the runner shaft 5 adjusts the rotating shaft 4, and one end of the latch adjusting rotating shaft 4 stretches out the password runner 3, and the other end is connected to ...

Embodiment 3

[0061] Multiple groups of the turntable positioning mechanism 11 can be arranged around the turntable 6 , and each group is provided with an elastic positioning protrusion 1108 . The purpose of multiple sets of turntable positioning mechanisms 11 is to confuse the audience and mislead illegal unlockers. Multiple sets of turntable positioning mechanisms 11 adopt exactly the same structure, no matter which group is rotated, they will have the same feeling of jamming. If you know the password, you can't judge it by the touch of the operation. Only the user of the combination lock can find the correct insertion position of the latch 12 according to the pre-set mark card slot 601 by randomly selecting a group of turntable positioning mechanisms 11 under the premise of knowing the password. Connecting position, realize the correct insertion of latch 12 and slot, further improve the security of combination lock. Other settings and working principles are the same as in Embodiment 1. ...

Abstract

The invention discloses a keyless blind-opening mechanical coded lock, and belongs to the technical field of mechanical coded locks. The keyless blind-opening mechanical coded lock is characterized inthat a rotating disc (6) and an inserting connecting disc (7) coaxially sleeve a rotating wheel shaft (5), a password rotating wheel (3) sleeves one end of the rotating wheel shaft (5) in a rotatingmode, and the inner end part of the password rotating wheel (3) penetrates through a vertical plate (1) and is connected with the rotating disc (6); a horizontally-arranged bolt (12) is arranged on the rotating disc (6), a plurality of forward inserting grooves (703) and reverse inserting grooves (704) are correspondingly formed in the inserting connecting disc (7); a rotating disc positioning mechanism (11) is arranged on one side of the rotating disc (6), and marking clamping slots (601) which are in butt joint with the inner side of the positioning mechanism are arranged on the outer circumferential end surface of the rotating disc (6). According to the keyless blind-opening mechanical coded lock, the form that the rotating disc and the inserting connecting disc are coaxially overlappedand are connected in an inserting mode is adopted, the inserting grooves are divided into the forward inserting grooves and the reverse inserting grooves, and inserting pins enter the inserting grooves to drive the inserting connecting disc to rotate forwards or backwards, so that the difficulty of any opening of the coded lock is improved; and through cooperation of the positioning mechanism, the safety and the anti-theft performance of the coded lock can be improved again.

Description

technical field [0001] A keyless blind-opening mechanical combination lock belongs to the technical field of mechanical combination locks. Background technique [0002] At present, combination locks in the prior art are divided into electronic combination locks and mechanical combination locks, and electronic combination locks or smart locks include fingerprint locks, card locks, iris, and facial recognition. It is undeniable that all electronic combination locks or smart locks have a common drawback: the higher the degree of electronization, the lower the reliability. Such as fire, humid weather environment, fear of vibration and static shock, fear of electromagnetic interference; you need to consider the power supply of the mains or the battery. The tutorials and tools for technical unlocking are sold everywhere on the Internet, and criminals can easily master the ability of technical unlocking . To sum up, people can never predict when the electronic function will fail,...
