Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
Referring to fig. 1 to 8, a mechanical lock with multiple unlocking modes includes:
a housing 1;
the lock cylinder assembly 2 is arranged in the shell 1 in a penetrating way and can rotate relative to the shell 1, and the lock cylinder assembly 2 comprises a knob shell 3, a mechanical lock cylinder 4 and a lock plate assembly 5, wherein part of the knob shell 3 is exposed out of the shell 1, the mechanical lock cylinder 4 is arranged in the knob shell 3 in a penetrating way, and the lock plate assembly 5 is assembled at the inner end of the mechanical lock cylinder 4;
an angle limiting piece is arranged between the knob casing 3 and the mechanical lock cylinder 4, and the angle limiting piece is an annular sheet body 6 which is sleeved on the mechanical lock cylinder 4 and is in clearance fit with each other;
the outer side of the annular sheet body 6 is provided with a convex point 6a, the inner side of the knob sleeve 3 is provided with a groove 3a, and the convex point 6a is clamped into the groove 3a, so that the annular sheet body 6 and the knob sleeve 3 are connected into a whole;
The above is the basic solution of the present invention, which adopts the annular sheet body 6 as the medium between the mechanical lock cylinder 4 and the knob housing 3, and realizes two opening functions stably and reliably, and the structure is simple enough. The specific working principle is as follows: 1. a user rotates the knob casing 3, at the moment, the annular sheet body 6 and the knob casing 3 rotate together and transmit the rotation to the mechanical lock cylinder 4 through abutting connection, so that the mechanical lock cylinder 4 drives the lock plate assembly 5 to move, and the unlocking or locking function is achieved; 2. a user directly inserts the mechanical lock cylinder 4 by a key and drives the mechanical lock cylinder 4 to rotate, and the annular sheet body 6 is provided with the rotation limiting groove 6b, so that the locking plate assembly 5 can be directly driven to move, and the unlocking or locking function is achieved.
Referring to fig. 5 to 6, the inside of the annular sheet body 6 is provided with a shoulder 6c, and the shoulder 6c can abut against the rotation stopper 4a and drive the mechanical lock cylinder 4 to rotate, so that the rotation casing can stably and reliably drive the mechanical lock cylinder 4 to rotate.
Referring to fig. 3, the mechanical lock cylinder 4 includes a key cylinder body 4b and a cylinder body sleeve 4c, a transmission column 4d is disposed at an end of the key cylinder body 4b, a transmission groove 4e is formed in the cylinder body sleeve 4c, the transmission column 4d is inserted in the transmission groove 4e, and a lock plate assembly 5 is assembled on the cylinder body sleeve 4 c. On one hand, the key core 4b can be rotated under the action of a key when inserted into the key, and meanwhile, the core sleeve 4c is driven to rotate; on the other hand, the knob housing 3 rotates the core cover 4c and thus also the key core 4b through the annular plate body 6.
Because the mechanical lock cylinder 4 and the knob sleeve 3 adopt a rotating mode when in use, and the rotating mode comprises forward rotation and reverse rotation, the misoperation condition of wrong steering can exist when a user uses the mechanical lock cylinder, and the mechanical lock cylinder cannot be unlocked or locked. Therefore, in order to limit the misoperation in time, the adopted method is as follows: referring to fig. 2, the locking plate assembly 5 has a flange 5a, and the housing 1 is provided with a turning stopper 1a, and the flange 5a can abut against the turning stopper 1a to form a limit fit. Once the operation direction is wrong, the flange 5a and the steering stop block 1a abut against each other and form interference when the rotation is less than one circle, so as to limit further rotation, and a user can correct the operation in time and quickly achieve the aim of correct operation.
Preferably, referring to fig. 6, the rotation limiting groove 6b is arranged at 90 degrees or 45 degrees or 180 degrees, and the arrangement modes at three angles can be adapted to the angle use requirements of most of the locks on the market. Of course, the rotation-restricting groove 6b may be set at other angles, and is not particularly limited.
Because the shape of the annular sheet body 6 is irregular and can be impacted by various external forces when in use, if the installation position is unstable, the annular sheet body can be dislocated, and the normal use effect is further influenced. Therefore, in order to allow a better working condition of the annular blade 6, the preferred mounting structure adopted is: the inner end of knob cover 3 is equipped with assembly groove 3b, cyclic annular lamellar body 6 inlay to be established assembly groove 3b in.
Example two

More specifically, referring to fig. 8, a rib 7d is disposed on the character wheel shaft 7a, and a code groove 7e corresponding to the correct code is disposed in the character wheel core 7 b.
The working principle when using does: when the character wheel core 7b is shifted to a correct password, the convex rib 7d is opposite to the password groove 7e, and the character wheel shaft 7a can be separated from the locking groove 3c under the action of the elastic piece 7c; when the character wheel core 7b is shifted to an incorrect password, the convex rib 7d is staggered with the password groove 7e and is abutted against the character wheel core 7b, and at the moment, the character wheel shaft 7a is continuously kept in the locking groove 3 c.
EXAMPLE III
The end of the knob housing 3 can be of various shapes, so that its mounting direction is not unique, in order to meet the individual requirements, in the following way: referring to fig. 3, the locking grooves 3c are uniformly distributed on the outer wall of the knob housing 3. During production, the character wheel shaft 7a can be matched with any one locking groove 3c, so that a multidirectional installation mode of the knob housing 3 is realized, and the requirements of various customers are met.
The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to utility model technical entity to any simple modification, change and the equivalent structure change of doing above embodiment, all still belong to the utility model discloses technical scheme's within the scope of protection.
