Judging from the laws of technological development in history, in the case of similar functions, simple and reliable things always replace complicated things, and it is the simple replacement of complicated things. Therefore, it is a popular practical new product, and it should replace the traditional disc-type mechanical combination lock and some electronic combination locks. Dial-type fully mechanical combination locks are widely used in safes, safes, filing cabinets, anti-magnetic fire cabinets, anti-theft doors, bank doors, warehouse doors, car doors, civil doors and mechanical blocking mechanisms. It can replace the existing traditional disc-type mechanical combination locks and some electronic combination locks. Provides an opportunity for some product updates.
Due to the popularity of electronic technology, many products are proud of using electronic structures. However, in some places, electronic products do not have absolute advantages, but mechanical products or electromechanical hybrid products are more practical. To give two examples: one is the ignition device of the gas stove. In the early days, the igniter of the transistor was all the rage, but it was not resistant to moisture, was easily damaged, and could not be separated from the battery. Over time, the mechanical (piezoelectric) ignition device that stores energy by twisting the knob by hand shows its superiority-simple and practical, and has become the mainstream of gas stove igniters. The second is the rearview mirror of the car and the rear door peep of the bus (single compartment), which were in danger of being replaced by electronic monitors, but people found that: the traditional rearview mirror and the ordinary rearview mirror above the bus driver , the observation effect is not worse than the electronic monitor, and it is simpler and more practical.
In fact, in traditional industries, it is also possible to find investment directions that are more secure than the so-called "new economy" but not less profitable. Combination lock is not a product that is frequently used, it can be said to be a semi-static product, and it is more practical to use mechanical methods. However, the amount of passwords in the electronic method is large, and people subjectively feel that it will be safer. The number of passwords of this patented product is close to that of electronic combination locks, and the operation is much faster than that of traditional mechanical combination locks. The dial-type fully mechanical combination lock is also a box-type mechanical combination lock, which is similar to the box-type mechanical combination locks of "Shajin" and "Legada" produced in the United States: they are all disc-type mechanical combination locks. , All have control lock tongue, all are coaxial operation to input password and open lock tongue. However, there is a big difference in the operation methods: the "Shajin" box-type mechanical password lock is connected to the active disk by the operation shaft, and then the active disk drives other password disks in turn. Therefore, when entering the password, the knob needs to be rotated forward several times and then reversed. After several circles, you can enter the password over and over again. The dial-type full-mechanical combination lock relies on a simple internal sequence dial to turn each password disc in turn. From the external operation point of view, it is similar to the operation of the old dial telephone: start from the starting point of the dial, turn the dial clockwise to a certain number, and then return to the starting point to enter a password. Repeat this until the last code is entered, and then turn the dial counterclockwise from the starting point to unlock the deadbolt.
