Abstract
A bolt type electronic lock comprises a cylindrical cam and a bolt piece, wherein the cylindrical cam is in transmission connection with a driving end of a rotating motor, a spiral groove is formed in the outer surface of the cylindrical cam, and a starting end and an end of the spiral groove are communicated through a linear groove; the upper surface of the bolt piece is provided with a limiting boss which is connected in the spiral groove and the linear groove in a sliding mode. The utility model overcomes the defects of the prior art, and the starting point end and the terminal point end of the spiral groove are communicated through the linear groove, so that the limit boss on the bolt piece can move from the terminal point end of the spiral groove to the starting point end of the spiral groove through the linear groove through manual operation to complete the retraction stroke, thereby playing the unlocking role.
Description
Technical Field
The utility model relates to the technical field of electronic locks, in particular to a bolt type electronic lock.
Background
Most of the transmission parts of the electronic locks on the market are in the lock bodies, so the lock bodies for the electronic locks are generally called electronic lock bodies. The electronic lock body is internally provided with a motor, a travel switch, a transmission bolt and other accessories.
When the existing electronic lock works normally, the lock pin can normally stretch back and forth, and the lock pin needs to be manually unlocked under some special conditions (such as power failure). The basic requirement for how to realize a manual unlocking mechanism is that the lock pin can be pulled out under special conditions without interfering with normal extension and retraction of the lock pin, which is a problem to be solved at present.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a bolt type electronic lock which overcomes the defects of the prior art, is reasonable in design, and has the function of communicating the starting point end and the terminal point end of a spiral groove through a linear groove, so that a limiting boss on a bolt piece can move from the terminal point end of the spiral groove to the starting point end of the spiral groove through the linear groove through manual operation to complete a retraction stroke, and then the unlocking function is realized.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
a bolt type electronic lock comprises a cylindrical cam and a bolt piece, wherein the cylindrical cam is in transmission connection with a driving end of a rotating motor, a spiral groove is formed in the outer surface of the cylindrical cam, and a starting end and an end of the spiral groove are communicated through a linear groove;
the upper surface of the bolt piece is provided with a limiting boss which is connected in the spiral groove and the linear groove in a sliding mode.
Preferably, circular arc transition is adopted between the two ends of the linear groove and the starting end and the terminal end of the spiral groove.
Preferably, the linear groove is provided parallel to an axial direction of the cylindrical cam.
The utility model provides a bolt type electronic lock. The method has the following beneficial effects: when the cylindrical cam cannot be driven to rotate reversely by rotating the motor, the linear groove can be used for communicating the starting end and the terminal end of the spiral groove, so that the limiting boss on the bolt piece can move to the starting end of the spiral groove from the terminal end of the spiral groove through the linear groove through manual operation, the retraction stroke is completed, and the unlocking effect is achieved.

the reference numbers in the figures illustrate:
1. a cylindrical cam; 2. a latch member; 3. a spiral groove; 4. a linear groove; 5. and a limiting boss.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings.
As shown in fig. 1-3, a bolt type electronic lock comprises a cylindrical cam 1 and a bolt piece 2, wherein the cylindrical cam 1 is in transmission connection with a driving end of a rotating motor, a spiral groove 3 is formed in the outer surface of the cylindrical cam 1, and a starting end and an end of the spiral groove 3 are communicated through a linear groove 4;
the upper surface of the bolt piece 2 is provided with a limiting boss 5, and the limiting boss 5 is connected in the spiral groove 3 and the linear groove 4 in a sliding mode.
The working principle is as follows:
when the bolt is used, the driving end of the motor is rotated to drive the cylindrical cam 1 to rotate, so that the limiting boss 5 on the bolt piece 2 slides from the starting end of the spiral groove 3 to the end of the spiral groove 3, and an extending stroke is completed; then, the driving end of the rotating motor drives the cylindrical cam 1 to rotate reversely, and then the limiting boss 5 on the bolt piece 2 slides from the end point end of the spiral groove 3 to the starting point end of the spiral groove 3 to finish a retraction stroke;
and after the limiting boss 5 slides to the terminal end of the spiral groove 3, when the cylindrical cam 1 cannot be driven to rotate reversely by rotating the motor, the starting end and the terminal end of the spiral groove 3 can be communicated through the linear groove 4, so that the limiting boss 5 on the bolt piece 2 can move to the starting end of the spiral groove 3 from the terminal end of the spiral groove 3 through the linear groove 4 through manual operation, the retraction stroke is completed, and the unlocking effect is realized.
In the present embodiment, the two ends of the linear groove 4 and the start end and the end of the spiral groove 3 are in circular arc transition. Thereby playing a certain guiding role when the limiting lug boss 5 slides in the linear groove 4.
In the present embodiment, the linear groove 4 is provided parallel to the axial direction of the cylindrical cam 1. So as to ensure that the cylindrical cam 1 is not influenced when the limiting lug boss 5 moves horizontally in the linear groove 4.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
