Problems solved by technology
But the defect of this combination lock is that it can only work normally when there is electricity; if the power is cut off, then they will lose their effect and bring unnecessary troubles to people.
However, the current mechanical combination locks have disadvantages such as complex structure, high cost, and easy damage.

Embodiment Construction
[0022] See figure 1 , a mechanical combination lock, the present invention is characterized in that it is composed of a lock sleeve, a combination disk put into the lock casing and an unlocker; wherein, the combination disk includes a disk body with a cylinder connected to a ring, sleeved on The inner sleeve core in the disc body, the slider between the disc body and the inner sleeve core, and the ring fixed on the inner sleeve core; the surface of the disc body is provided with an unlocking hole A and a scale line, and the top of the inner sleeve core is also There is an unlocking hole B that is as circular as the unlocking hole A on the surface of the disc body; there are at least three equal annular convex lines B on the ring fixed at the bottom of the inner core and at least three bayonets A on the outside; on the top surface of the slider A round pin hole with a step is opened in the longitudinal direction and a cylindrical round pin is inserted therein. There are at leas...

The invention discloses a mechanical coded lock. The coded lock is composed of a lock sleeve, a coded plate placed in the lock sleeve and an unlocking device. The coded plate comprises a disc body, an inner sleeve core, a slide block and a circular ring, wherein the disc body is provided with a barrel body and connected with the circular ring, the inner sleeve core is sleeved with the barrel body of the disc body, the slide block is arranged between the disc body and the inner sleeve core, and the circular ring is fixed onto the inner sleeve core; the lock sleeve is constituted by an outer sleeve and a lock sleeve inner wall fixed to the interior of the outer sleeve. The mechanical coded lock has the advantages that in the locking state, arc chutes in the bottoms of cylinder round pins and annular protruding strips B on the circular ring are not located on the same arc, due to the fact that it is designed in advance that a distance equivalent to the diameters of one or more unlocking holes exists between each side of each cylinder round pin and the corresponding end of the corresponding annular protruding strip B on the circular ring, and when the disc body is rotated to one end of each annular protruding strip B and in contact with one side of the corresponding cylinder round pin, corresponding unlocking holes A and unlocking holes B are staggered, thereby a code cannot be cracked.
Description
technical field [0001] The invention belongs to the field of locks, in particular to a mechanical combination lock. Background technique [0002] With the development of science and technology and the improvement of living standards, people's awareness of property protection is becoming stronger and stronger. The coded locks that people use are usually electronic coded locks at present, are made of lock body and controller, and people can carry out operations such as password verification on the controller. But the defective of this coded lock is: just can work normally under the situation that has electricity; If once cut off power, so they can lose effect, bring unnecessary trouble to people. The mechanical combination lock is not limited by electricity or other conditions. However, the current mechanical combination lock has disadvantages such as complex structure, high cost, and easy damage. Contents of the invention [0003] The present invention is designed to ove...
