Embodiment Construction

[0025] Such as Figure 1 to Figure 7 As shown, a hand-cranked alarm includes a support 1. The support 1 is set in the shape of a bracket with a small upper width and a large lower width. A transmission box 3 is connected. Specifically, the circumferential side of the transmission box 3 and the upper surface of the support 1 can be connected by detachable connection methods such as pins. The transmission box 3 is set as a hollow cylindrical structure, and the axis of the transmission box 3 is along the horizontal The direction is set, and the input shaft 5 is coaxially rotatable through one side end surface of the transmission box 3, and the crank handle 2 is fixedly connected to the end surface of the transmission box 3 coaxially with the input shaft 5, and the outer circumferential surface of the crank handle 2 is provided with anti-slip protrusions , so that when the power is input through the rotation of the crank handle 2, the hands and the surface of the rocker handle 2 w...

Abstract

The invention discloses a hand-operated alarm. The hand-operated alarm comprises a support, the upper end of the support is connected with a transmission case, an input shaft is coaxially and rotatably arranged on one end face penetrating through the transmission case, a rocking handle is coaxially and fixedly connected with the input shaft, the other end of the input shaft is coaxially and fixedly connected with a driving disc, two planet wheels are arranged on the end face of the driving disc, the planet wheels can rotate along the axes of the planet wheels, meanwhile, a gear ring is arranged to be meshed with the two planet wheels, a sun wheel is arranged to be meshed with the two planet wheels, a transmission shaft is coaxially and fixedly connected to the end face of the sun wheel, abuzzer box is coaxially and fixedly arranged on the other side end face of the transmission case, multiple buzzer blades are uniformly distributed on the side end face of the transmission shaft penetrating through the buzzer box, multiple air outlets are formed in the circumferential side face of the buzzer box, and multiple air inlets are formed in the end face of the buzzer box. According to thehand-operated alarm, by arranging a planet gear transmission system, the power transmission efficiency is improved, the overall size is reduced, the operation is time-saving and labor-saving, and thealarm effect of the alarm is guaranteed.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to a hand-cranked alarm. Background technique [0002] Hand siren is a tool that can provide effective alarm without power support. It is mostly used for emergency warning when emergencies occur in civil defense, military forces, mines, airports, oil depots and other places. However, the existing hand siren The alarm needs to be shaken to a certain speed to achieve the ideal alarm effect. Due to the poor transmission efficiency of the transmission system, it is time-consuming and laborious to operate by hand, and the entire manual alarm device is too large to be carried easily. At the same time, the existing hand-operated The clutch device of the alarm is generally converted into linear motion through the hand rocker to realize the connection of the clutch device. Here, the conversion of linear motion through rotary motion reduces the utilization of energy. Contents of the inventio...
