Abstract
The utility model relates to an escape indicator, comprising a shell; a front panel of the shell is provided with a scanning window; and the rear part of the scanning window is provided with a laser head which is aligned with the scanning window and is fixed on a rotating shaft. The escape indicator is characterized in that the shell of the lower part of the rotating shaft is internally provided with a motor; the escape indicator also comprises a gear transmission mechanism positioned in the shell; the gear transmission mechanism comprises a driving shaft, a first driven shaft and a second driven shaft; the driving shaft is provided with a first incomplete gear; the first driven shaft is provided with a second incomplete gear; the second driven shaft is provided with a complete gear; the teeth parts of the first incomplete gear and the second incomplete gear are completely meshed with the complete gear; the driving shaft is also provided with a first transmission gear; the first driven shaft is also provided with a second transmission gear; the first transmission gear and the second transmission gear are meshed; the driving shaft is connected with an output shaft of the motor; and the rotating shaft is connected with the second driven shaft. The escape indicator adopts the gear transmission mechanism to drive the rotating shaft, and has smooth and stable operation.
Description
(1) technical field
The utility model relates to a kind of escape indicator.
(2) background technology
The warning when escape indicator is used for breaking out of fire and the indication of escape direction, generally comprise housing, offer on the front panel of housing and strafe window, the rear of strafing window is provided with radium-shine head, this radium-shine head is aimed at the described window of strafing, radium-shine head is fixed in the rotating shaft, comes back rotation by the drive mechanism rotating shaft, thereby reaches strafing of laser that radium-shine hair goes out.Existing driving mechanism is complicated, and stability is not enough, causes easily to rotate to lose efficacy.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing escape indicator, the utility model provides a kind of escape indicator of radium-shine stability of rotation.
The technical scheme in the invention for solving the technical problem is: a kind of escape indicator, comprise housing, offer on the front panel of described housing and strafe window, the described rear of strafing window is provided with radium-shine head, this radium-shine head is aimed at the described window of strafing, described radium-shine head is fixed in the rotating shaft, is provided with motor in the housing of the below of described rotating shaft; Also comprise the gear drive that is positioned at described housing, this gear drive comprises main drive shaft, first driven shaft and second driven shaft, described main drive shaft is provided with first partial gear, described first driven shaft is provided with second partial gear, described second driven shaft is provided with complete gear, complete tooth-formation of gear part of described first partial gear and second and described complete gearing mesh; Also be provided with first transmission gear on the described main drive shaft, also be provided with second transmission gear on described first driven shaft, described first transmission gear and the engagement of second transmission gear; Described main drive shaft is connected with the output shaft of described motor, and described rotating shaft is connected with described second driven shaft.
The utility model in use, the driven by motor main drive shaft rotates, under the effect of first transmission gear and second transmission gear, main drive shaft drives first driven shaft and rotates.When the main drive shaft and first driven shaft rotate, first partial gear and second complete gear rotate by driving second driven shaft with complete gear meshing transmission, and the direction of rotation of the rotation direction of first partial gear, second driven shaft during with gear matched transmission fully and second partial gear second driven shaft during with complete gear matched transmission.
The beneficial effects of the utility model are: adopt the gear drive countershaft to drive, operate steadily, stablize.
(4) description of drawings
Fig. 1 is the synoptic diagram of drive motor.
Fig. 2 is the structural representation of gear drive.
Fig. 3 is radium-shine head and the wiring layout of gear drive.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of escape indicator, comprise housing, offer on the front panel of described housing and strafe window, the described rear of strafing window is provided with radium-shine 1, aim at the described window of strafing for this radium-shine 1, described radium-shine 1 is fixed in the rotating shaft 2, is provided with motor 3 in the housing of the below of described rotating shaft 2; Also comprise the gear drive that is positioned at described housing, this gear drive comprises main drive shaft 4, first driven shaft 5 and second driven shaft 6, described main drive shaft 4 is provided with first partial gear 7, described first driven shaft 5 is provided with second partial gear 8, described second driven shaft 6 is provided with complete gear 9, the parts of tooth of described first partial gear 7 and second complete gear 8 and 9 engagements of described complete gear; Also be provided with first transmission gear 10 on the described main drive shaft 4, also be provided with second transmission gear 11 on described first driven shaft 5, described first transmission gear 10 and 11 engagements of second transmission gear; Described main drive shaft 4 is connected with the output shaft of described motor 3, and described rotating shaft 2 is connected with described second driven shaft 6.
The utility model in use, motor 3 drives main drive shafts 4 and rotates, under the effect of first transmission gear 10 and second transmission gear 11, main drive shaft 4 drives first driven shaft 5 and rotates.When the main drive shaft 4 and first driven shaft 5 rotate, first partial gear 7 and second complete gear 8 drive second driven shaft 6 by the engaged transmission with complete gear 9 and rotate, and the direction of rotation of first partial gear 7, second driven shaft 6 when the rotation direction of second driven shaft 6 cooperates transmission with second partial gear 8 with complete gear 9 when gear 9 cooperates transmission fully.
