Embodiment Construction

[0011] figure 1 in and figure 2 The combined mechanism of intermittent transmission and connecting rod shown in has: a movable frame (18) and a breathing part (2). Among them, the movable frame (18) is equipped with a motor 1, a rotating cylinder (9), an adjustment plate (10), a rotary shaft (12), a pin wheel (16), a sheave (15), and a connecting rod (17). The bearing (13) and the guide rod (7) define the movement route of the frame; the breathing part (2) is driven by the motor 2, the gear (4) and the rack (5), and moves along the guide post (6).

[0012] Rotary cylinder (9) is fixed on the adjusting disc (10), and adjusting disc (10) is fixed on the rotating shaft (12) through cylindrical pin (11); One end of rotating shaft (12) is fixed with a sheave (15), and the groove Wheel (15) fits with the pin wheel (16) fixed on the motor 1; the round pin (19) on the pin wheel (16) is sleeved on the connecting rod (17); one end of the connecting rod (17) passes through the connect...

Abstract

The invention provides a combined mechanism of intermittent drive and connecting bar and the application thereof. The combined mechanism has a movable stander (18) and a breathing part (2), wherein, the movable stander (18) is provided with an electrical motor 1, a revolving drum (9), an adjusting plate (10), a rotor (12), a pin wheel (16), a scored pulley (15) and a connecting bar (17), movement route of the stander is defined by a direct bearing (13) and a leader (7); the breathing part (2) is driven by an electrical motor 2, gear (4) and rack (5), and moves along a guide pole (6).

Description

technical field [0001] The invention relates to a mechanical structure, in particular to an improvement of the internal mechanical structure of medical teaching equipment. technical background [0002] In the existing simulated abdominal palpation practice equipment for medical teaching, the structure between the liver and gallbladder model group located in the chest cavity and the abdominal parts is very compact. When replacing the model, the model group must withdraw from the physiological position (or avoid the liver and gallbladder model group by the abdominal mechanism) before the model can be replaced; then return the model group (or the abdominal mechanism) to its original position. Usually, the avoidance action between the model group and the abdominal parts and the replacement of the model are respectively driven by two motors, and the replacement of the model is often driven by flexible transmission such as a chain. However, the alternate action of the two motors ...
