Description
Technical field
The present invention relates to mechanical structure, specifically refer to a kind of improvement of medical teaching device interior mechanical structure.
Technical background
In the simulation abdominal touch exerciser of existing medical teaching, the liver and gall model group and the structure between the belly parts that are positioned at the thoracic cavity are very compact.When changing model, model group must withdraw from physiological location (or liver and gall model group dodged by the belly parts) just can carry out the replacing of model; Send model group (or belly parts) back to original position more afterwards.Usually, the action of dodging between model group and belly parts is adopted two motor driving respectively with the model replacing, and model is changed flexible transmissions such as often adopting chain.Yet two motor alternating movements are not only lost time, and also can cause parts damaged in collision accident because of signal fault; Or rock the damage that causes Detecting element because of chain.
In addition, during simulated respiration, model group also will rise and fall with belly and does corresponding displacement (close when air-breathing, during expiration away from), could meet human body physiological characteristics more.Existing equipment is not an afunction, is exactly complex structure.
Summary of the invention
The objective of the invention is to overcome the deficiency that said structure exists, the combined mechanism of a kind of intermittently-driving and connecting rod is provided, it has: two motors, a pin wheel, a sheave, a rotating cylinder, a connecting rod, a connecting pin, a respiratory component, several trough; Round pin on the pin wheel begins to be rotated counterclockwise from start bit under motor driving, and the supporting effect by connecting rod pushes away respiratory component with this mechanism; After round pin enters the radial groove of sheave, turn over a fixing corner by turning axle, straight pin, adjustment dish, drive rotating cylinder; After round pin is deviate from the radial groove of sheave, by the traction action of connecting rod that this mechanism is multiple to original position again.Because connecting rod one end is enclosed within on the round pin of pin wheel, the connecting pin of the other end is by the translot of fixed frame and the curvilinear groove together support on the respiratory component, when respiratory component is done elevating movement, top curvilinear groove will drive whole intermittent drive mechanism reciprocating action by the stay bolt effect of connecting pin and connecting rod.
According to the application of the combined mechanism that the invention allows for this intermittently-driving and connecting rod, be used for the replacing of medical teaching equipment internal organ model.By the rotation of rotating cylinder, the internal organ model that is fixed on the rotating cylinder is changed the position; Cooperate the motion of respiratory component by the supporting effect of connecting rod, reach the purpose of simulation human body physiological characteristics.
The invention has the beneficial effects as follows: the combination of (1) the present invention first Application intermittently-driving and connecting rod in like product, use a motor driving, in one-period, finished the stepping down of model, replacing and homing action continuously.Action is accurately coordinated, and has avoided the damage of electromechanical device, also can save a motor and shorten the operating time.(2) this mechanism utilizes the effect of curvilinear groove and connecting rod, has realized that internal organs models such as liver, courage, spleen with breathing ventrad near when air-breathing () or away from the displacement action of (during expiration), meet human body physiological characteristics more.
Description of drawings
As accompanying drawing
Accompanying drawing 1 is the whole profile of this mechanism, wherein (1) translot (2) respiratory component (3) curvilinear groove
(4) gear (5) tooth bar (6) guide pillar (7) guide rod (15) sheave (16) pin wheel (19) round pin (20) radial groove
Accompanying drawing 2 is whole plan views of this mechanism, wherein (8) connecting pin (9) rotating cylinder (10) adjustment dish (11) straight pin (12) turning axle (13) guide bearing (14) fixed frame (15) sheave (16) pin wheel (17) connecting rod (18) movable machine frame (19) round pin
Specific embodiment
Reach the intermittently-driving shown in Fig. 2 and the combined mechanism of connecting rod among Fig. 1, have: (18) respiratory components of movable machine frame (2).Wherein movable machine frame (18) is equipped with motor 1, rotating cylinder (9), adjustment dish (10), turning axle (12), pin wheel (16), sheave (15), connecting rod (17), has been stipulated the moving line of frame by guide bearing (13) and guide rod (7); Respiratory component (2) is driven by motor 2, gear (4), tooth bar (5), moves along guide pillar (6).
Rotating cylinder (9) is fixed on the adjustment dish (10), and adjustment dish (10) is fixed on the turning axle (12) by straight pin (11); One end of turning axle (12) is fixed a sheave (15), and sheave (15) agrees with the pin wheel (16) that is fixed on the motor 1; Round pin (19) on the pin wheel (16) is sleeved on the connecting rod (17); One end of connecting rod (17) is nested in the curvilinear groove (3) of translot (1) on the fixed frame and respiratory component (2) by connecting pin (8).Various internal organ models are fixed on the rotating cylinder (9), accurately replace with implementation model.
When respiratory component (2) was in extreme lower position and break-off, the pin wheel on the motor 1 (16) began to be rotated counterclockwise.Since the supporting effect of connecting pin (8), round pin (19) drivening rod (17) swing on the pin wheel (16), and the whole model group (containing the spleen model component) that is fixed on the movable machine frame (18) is withdrawed to the right; In round pin (19) enters the radial groove of sheave (15), when (20), begin to stir sheave (15) and turn clockwise, deviate from during to the next position.Finished the internal organ model and changed this moment, and round pin (19) remains in operation, and sends whole model group to working position again.
