Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of height and weight testers, and in particular relates to a movable baffle locking mechanism for a height and weight tester. Background Art
[0002] The height and weight tester is a scientific device for measuring human height and weight parameters. Its application scenarios include but are not limited to primary and secondary schools, colleges and universities, hospitals and military units.
[0003] Currently, most height and weight testers on the market use a method where the baffle is moved to the top of the head to measure and count. After the baffle returns to its original position, it is generally fixed by a motor self-locking. In this way, when the equipment is not used for a long time, the motor is still working and consuming electricity, resulting in excessive motor power consumption. Utility Model Content
[0004] The utility model aims to provide a locking mechanism for a movable baffle of a height and weight tester, so as to solve the problem that the movable baffle of the existing height and weight tester is generally fixed by a motor self-locking after returning to a position, which leads to a large consumption of motor power.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A locking mechanism for a movable baffle of a height and weight tester comprises a fixed frame, a linear guide rail is mounted on the fixed frame, a sliding seat is clamped on the linear guide rail, a connecting seat is connected to the sliding seat, a movable baffle is connected to the connecting seat, and a locking mechanism is also provided. The locking mechanism comprises a mounting seat, an electromagnetic lock is provided at the bottom of the mounting seat beside the connecting seat, a micro switch is provided on the mounting seat above the movable baffle, an idler wheel is mounted on the fixed frame, and a stepping motor is also provided. A synchronous wheel is mounted on the output shaft of the stepping motor, and the synchronous wheel and the idler wheel are connected through a synchronous belt transmission. A movable plate is provided on the synchronous belt, and the movable plate is connected to the sliding seat. A main control MCU is also provided, and the electromagnetic lock, the stepping motor, and the micro switch are respectively connected to the main control MCU by electrical signals.
[0007] Furthermore, a connecting rib plate is provided between the movable baffle and the connecting seat.
[0008] Furthermore, the electromagnetic lock can be detachably mounted on the mounting seat.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0010] 1. The utility model comprises a fixed frame, a linear guide rail is installed on the fixed frame, a sliding seat is clamped on the linear guide rail, a connecting seat is connected to the sliding seat, a moving baffle is connected to the connecting seat, and a locking mechanism is also provided, the locking mechanism comprises a mounting seat, an electromagnetic lock is provided at the bottom of the mounting seat next to the connecting seat, a micro switch is provided on the mounting seat above the moving baffle, an idler wheel is installed on the fixed frame, and a stepping motor is also provided, a synchronous wheel is installed on the output shaft of the stepping motor, the synchronous wheel and the idler wheel are connected through a synchronous belt transmission, a moving plate is provided on the synchronous belt, the moving plate is connected to the sliding seat, and a main control MCU is also provided, and the electromagnetic lock, the stepping motor, and the micro switch are respectively connected to the main control MCU by electrical signals.
[0011] Through this setting, the synchronous wheel is installed on the output shaft of the stepper motor. The transmission system composed of the synchronous wheel, the synchronous belt and the idler wheel can drive the moving plate to move up and down, thereby driving the sliding seat to move up and down along the linear guide rail, and finally realizing the up and down movement of the moving baffle. When the moving baffle for measuring height moves upward through the electromagnetic lock, the lock tongue of the electromagnetic lock first retreats and then resets and rebounds, and the moving baffle contacts the top micro switch. After receiving the switch signal, the main control MCU controls the stepper motor to stop running. At this time, the moving baffle naturally drops under the action of gravity until the connecting seat is stuck by the lock tongue of the electromagnetic lock, and the descending action stops, thereby locking the moving baffle, greatly saving electric energy, and effectively solving the problem that the existing height and weight tester generally adopts motor self-locking to fix the moving baffle after returning to its position, resulting in large motor power consumption.
