The utility model provides a gear box motor for lock, small, the mountable is in the lock core, directly drives the spring bolt, and the energy consumption is low.
Description
Technical Field
The utility model relates to an intelligence lock technical field, specifically speaking relates to a gear box motor and lock for lock.
Background
The thickness of the existing intelligent lock gear box on the market is about 24cm, and the intelligent lock gear box cannot be installed in the lock body due to the thick thickness to realize intelligent lock opening and closing, so that the installation space is large when the intelligent lock gear box is used, and the energy consumption is high due to the complex structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gear box motor for lock, it is small, the mountable in the lock core, directly drive the spring bolt, the energy consumption is low.
The utility model discloses a technical scheme that is used for gear box motor of lock and lock to adopt is:
the utility model provides a gear box motor for lock, includes the casing and installs the drive arrangement in the casing, drive arrangement includes motor, worm, skewed tooth group, drive gear and output gear, the worm is fixed in the drive shaft of motor, skewed tooth group and worm meshing, drive gear and skewed tooth group meshing, output gear and drive gear meshing, output gear is used for driving the spring bolt.
Preferably, the motor is a micro direct current motor.
Preferably, the skewed tooth group, the transmission gear and the output gear are all fixed in the shell through a fixing shaft.
Preferably, the shell comprises a left shell and a right shell which are connected in a clamping mode, and a cavity is formed between the left shell and the right shell.
A door lock comprises the gear box motor.
The utility model discloses a beneficial effect for gear box motor of lock is: after the motor drives the worm, the worm drives the helical tooth group, the helical tooth group drives the output gear through the transmission gear after realizing the adjustment of the torque and the rotating speed, and the output gear is used for directly driving the lock tongue. Because the driving part only comprises the motor, the worm, the helical tooth group, the transmission gear and the output gear, the driving part is relatively small in size and can be installed in the lock core, and the output gear directly drives the lock tongue, so that the energy consumption is low.
Drawings
Fig. 1 is an exploded view of the gear box motor for door lock of the present invention.
Fig. 2 is a schematic structural diagram of the gear box motor for door lock of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1 and 2, the gear box motor for the door lock comprises a housing 10 and a driving device 20 arranged in the housing, wherein the driving device 20 comprises a motor 22, a worm 23, a helical tooth group 24, a transmission gear 25 and an output gear 26, the worm 23 is fixed on a driving shaft of the motor 22, the helical tooth group 24 is meshed with the worm 23, the transmission gear 25 is meshed with the helical tooth group 24, the output gear 26 is meshed with the transmission gear 25, and the output gear 26 is used for driving the latch bolt.
After the motor drives the worm, the worm drives the helical tooth group, the helical tooth group drives the output gear through the transmission gear after realizing the adjustment of the torque and the rotating speed, and the output gear is used for directly driving the lock tongue. Because the driving part only comprises the motor, the worm, the helical tooth group, the transmission gear and the output gear, the driving part is relatively small in size and can be installed in the lock core, and the output gear directly drives the lock tongue, so that the energy consumption is low.
The motor is a micro direct current motor. The efficiency of the micro direct current motor is generally higher than that of other types of motors, so that the same output power is achieved, the energy consumption is lower, and the volume is smaller.
The helical set 24, the transmission gear 25 and the output gear 26 are all fixed in the housing by a fixed shaft 30.
The housing 10 comprises a left shell 14 and a right shell 12 which are connected in a clamping manner, and a cavity is formed between the left shell 14 and the right shell 12 and is used for placing the driving device 20. The left shell 14 and the right shell 12 are detachably connected, so that the assembly, detection and maintenance of the gearbox motor are facilitated.
A door lock comprises the gear box motor.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
