Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Central control brake system provided in an embodiment of the present invention is used for packaged type equipment, including：
First pedal 10, the second pedal 20, axis 30 and bevel gear set, structure are as shown in Figure 2；
Wherein, bevel gear set includes first bevel gear 41, second bevel gear 42 and third hand tap gear 43；First pedal 10,
First bevel gear 41 and axis 30 are relatively fixed；Second pedal 20 and second bevel gear 42 are relatively fixed, and the second pedal 20 can
It is rotated relative to axis 30；The both ends connection braking mechanism and castor 50 of axis 30 pass through operating pedal and bevel gear set transmission control
The rotation of axis 30 processed come realize brake, solution brake or the movement that takes the air line, concrete structure and principle reference the prior art, herein
It repeats no more；
It is linked by third hand tap gear 43 between first bevel gear 41 and second bevel gear 42, and rotation side between the two
To opposite.
When operator steps on the first pedal 10 by foot, and first bevel gear 41 is allowed to rotate, then axis 30 is driven to rotate in same direction,
Axis 30 then generates the action that brake either solves brake (or the movement that takes the air line) to the brake switch of castor 50.When the first pedal
10 when rotating down, and the second pedal 20 is rotated up simultaneously；Conversely, when operator steps on the second pedal 20,20 band of the second pedal
Dynamic second bevel gear 42, second bevel gear 42 drive 42 counter motion of second bevel gear, the second cone tooth by third hand tap gear 43
Wheel 42 then drives axis to rotate in same direction, and realizes that the brake of castor either solves brake (or the movement that takes the air line).
It can be seen from the above technical scheme that central control brake system provided in an embodiment of the present invention, due to using
Bevel Gear Transmission scheme, compared with using spur gear parallel axes in the prior art, entire Zhong Kong mechanisms are more compact, be periphery its
He has vacateed space at component setting.
Preferably, the second pedal 20 can be around 30 central axis of axis.It is relatively solid in view of the first pedal 10 and axis 30
Fixed, then it is around 30 central axis of axis to be equivalent to the first pedal 10 also, you can to allow the shaft of two pedal shafts to keep an axis
The heart can allow two pedals to have same movement locus, institute to be designed in order to peripheral structure, is also easier on the shape handles.Tool
Body, 42 coaxial line of first bevel gear 41 and second bevel gear at this time, both perpendicular to third hand tap gear 43.
In order to advanced optimize above-mentioned technical solution, first bevel gear 41 and second bevel gear 42 may be contained within first and step on
Between plate 10 and the second pedal 20, as shown in Fig. 2, third hand tap gear 43 be engaged in first bevel gear 41 and second bevel gear 42 it
Between, i.e., entire bevel gear set all concentrated settings are made into the structure of entire central control brake system more between two pedals
It is compact.
Central control brake system provided in an embodiment of the present invention further includes for the walking mounted on packaged type equipment
Holder device in mechanism；Walking mechanism is such as the chassis frame in trolley type movable equipment；
Third hand tap gear 43 is installed on holder device by bearing, to ensure its steady operation.Its structure is referred to Fig. 2
Shown, holder device is installed on longeron by crossbeam herein.
Further, the second pedal 20 is installed on holder device by bearing, and the second pedal 20 and second bevel gear 42 are solid
Fixed connection, second bevel gear 42 have gap coaxial sleeve to be set to axis 30.It is not connected between second bevel gear 42 and axis 30, is
Pass through the second pedal 20 or the driving rotation of third hand tap gear 43.
Fixed relation between multiple components can by being fixedly connected two-by-two in it, or by with other component
Between connection relation realize.
In the present embodiment, be directly fixedly connected between the second pedal 20 and second bevel gear 42, make it is compact-sized, specifically
Pin either key (or other modes) can be passed through.
Similar, the first pedal 10 is fixedly connected with first bevel gear 41, and first bevel gear 41 is fixedly connected with axis 30,
Make compact-sized.Preferably, either key (or other modes) fixes company by pin for the first pedal 10 and first bevel gear 41
It connects.By pin, either key (or other modes) is fixedly connected first bevel gear 41 with axis 30.
The embodiment of the present invention additionally provides a kind of trolley type movable medical equipment, including central control brake system,
Central control brake system is such as above-mentioned central control brake system.
This programme is described further with reference to specific embodiment：
The present invention uses bevel gear (or being bevel gear) transmission scheme, two pedals real by the bevel gear kind of drive
When now stepping on next pedal, for brake, brake for solution when stepping on another pedal.As shown in Figure 2：First pedal 10 and first is bored
By pin, either key (either other modes) is fixedly connected with the second pedal 20 to gear 41 and second bevel gear 42 passes through pin or key
(or other modes) are fixedly connected.Either key or other connection types fix company by pin for first bevel gear 41 and axis 30
It connects.Second bevel gear 42 and axis 30 can then be relatively rotated and (be not connected to, gap set).First bevel gear 41 and second bevel gear
Linkage is generated by third hand tap gear 43 between 42, and rotation direction between the two is exactly the opposite.When operator passes through foot
Step on the first pedal 10 allow first bevel gear 41 rotate when, then drive axis 30 to rotate in same direction, the then brake to castor 50 of axis 30
Switch generates the action that brake either solves brake (or the movement that takes the air line).When the first pedal 10 rotates down, the second pedal
20 are rotated up simultaneously；Conversely, when operator steps on the second pedal 20, the second pedal 20 drives second bevel gear 42, the second cone
Gear 42 drives 42 counter motion of second bevel gear, second bevel gear 42 then axis to be driven to turn in the same direction by third hand tap gear 43
It is dynamic, realize that the brake of castor either solves brake (or the movement that takes the air line).
In conclusion the embodiment of the invention discloses a kind of central control brake system, key problem in technology point is in castor
Prosecutor formula uses Bevel Gear Transmission, is fixed by a bevel gear and axis, another bevel gear relatively rotates with axis, and
By third gear drive between two bevel gears, to realize the middle control of castor.The present invention is as a result of Bevel Gear Transmission
Scheme, additionally, due to the structure of bevel gear, can allow the shaft of two pedal shafts to keep one so entire Zhong Kong mechanisms are more compact
A axle center can allow two pedals to have same movement locus；Institute designs in order to peripheral structure, also more holds on the shape handles
Easily.The embodiment of the invention also discloses a kind of trolley type movable medical equipments using above-mentioned central control brake system.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
