Abstract
The utility model discloses a kind of electric padlock not stall electric motor clutch, comprise motor, the eccentric wheel be connected with the output shaft of motor, projection on eccentric wheel stretches into lock bolt, and can rotate in lock bolt, lock bolt is provided with return spring, when projection rotation makes lock bolt be separated with lock bridge groove, return spring stress deformation, lock bridge ejection lock bolt is unblanks; When pressing down lock bridge and making lock bridge groove align with lock bolt, return spring resets to be and shuts, and its improvements are: on eccentric wheel, arrange the magnetic block of answering with external detection Switch Controller, lock bolt is arranged for the protruding idle running groove rotated.
Description
Technical field
The utility model belongs to electric padlock technical field, relates to a kind of electric padlock not stall electric motor clutch in this field specifically.
Background technology
Current electric padlock, clutch is all adopt electromagnet clutch structure, needs motor corresponding with it to have larger drive current; As stressed in electric motor clutch cannot normal switch lock, easily there is motor rotation blockage, cause the problems such as circuit burnout.
Utility model content
Technical problem to be solved in the utility model, is just to provide the little electric padlock of a kind of drive current not stall electric motor clutch.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electric padlock not stall electric motor clutch, comprise motor, the eccentric wheel be connected with the output shaft of motor, projection on eccentric wheel stretches into lock bolt, and can rotate in lock bolt, lock bolt is provided with return spring, when projection rotation makes lock bolt be separated with lock bridge groove, return spring stress deformation, lock bridge ejection lock bolt is unblanks; When pressing down lock bridge and making lock bridge groove align with lock bolt, return spring resets to be and shuts, and its improvements are: on eccentric wheel, arrange the magnetic block of answering with external detection Switch Controller, lock bolt is arranged for the protruding idle running groove rotated.
Further, described motor is reduction gearing motor.
Further, described projection is cylindrical protrusions.
The beneficial effects of the utility model are:
Electric padlock disclosed in the utility model is stall electric motor clutch not, when the magnetic block on eccentric wheel turn to align with external detection switch time, motor will stop operating, so ensure that the projection on eccentric wheel is each all at same position when unblanking; Lock bolt is free turn trough, even if under unlocking condition, projection also can normal rotation, and motor is stall never, realizes perfect clutch state.In addition, the structure that this electric motor clutch does relative to existing electromagnet clutch is improved, and the motor that it can be little with drive current is matched, and versatility is stronger.
Accompanying drawing explanation
Fig. 1 is the detonation configuration schematic diagram of electric padlock disclosed in the utility model embodiment 1 not stall electric motor clutch.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in Figure 1, present embodiment discloses a kind of electric padlock not stall electric motor clutch, comprise reduction gearing motor 1, the eccentric wheel 2 be connected with the output shaft of reduction gearing motor, cylindrical protrusions 21 on eccentric wheel stretches into lock bolt 4, and can rotate in lock bolt, lock bolt is provided with return spring 5, when needs are unblanked, reduction gearing motor will rotate, thus the cylindrical protrusions on band movable eccentric wheel is rotated in lock bolt, lock bolt is separated, now return spring stress deformation with lock bridge groove, lock bridge ejection lock bolt is unblanks; When pressing down lock bridge and making lock bridge groove align with lock bolt, return spring resets to be and shuts, and in addition, eccentric wheel arranges the magnetic block 3 of answering with external detection Switch Controller, lock bolt arranges the idle running groove 41 rotated for cylindrical protrusions.When the magnetic block on eccentric wheel turn to align with external detection switch time, motor will stop operating, so ensure that the projection on eccentric wheel is each all at same position when unblanking; Lock bolt is free turn trough, even if under unlocking condition, projection also can normal rotation, and motor is stall never, realizes perfect clutch state.
Claims (3)
1. an electric padlock not stall electric motor clutch, comprise motor, the eccentric wheel be connected with the output shaft of motor, projection on eccentric wheel stretches into lock bolt, and can rotate in lock bolt, lock bolt is provided with return spring, when projection rotation makes lock bolt be separated with lock bridge groove, return spring stress deformation, lock bridge ejection lock bolt is unblanks; When pressing down lock bridge and making lock bridge groove align with lock bolt, return spring resets to be and shuts, and it is characterized in that: on eccentric wheel, arrange the magnetic block of answering with external detection Switch Controller, lock bolt is arranged for the protruding idle running groove rotated.
