It is easily controllable.
Problem to be solved in the utility model be realize one kind can easily realize castor all locking and can be same
When suitable for different size castor foot-operated brake mechanism 100.
Described in detail according to one of the utility model foot-operated brake mechanism 100 specific implementation with reference to Fig. 1 to Figure 10
Example.
Specifically, foot-operated brake mechanism 100 includes base assembly 1 (including chassis 11 and preceding prong 12), caster support
Block 7, latch assembly 4 (including treadle 41 and switching metal plate 42), guide support 422, pin, step on pipe support block 8, stopping means
(including anti-limited block 5 and multiple service brake limited blocks 6), castor 2 and two aviation castors 3 etc. are controlled in two.Footbrake machine
Controlled while structure 100 can be simple by way of depressing and unclamping treadle 41 four castors (including controlled in two castor 2 with
And two aviation castors 3, similarly hereinafter) locking and release, to realize the brake and movement of equipment (such as healing robot).
Treadle 41 for example steps on pipe, hexagon shaft section 4111 such as hexagonal bar, song by bar portion 411 such as transverse tube, pedal position 413
Handle 412, anti-limited block 5 etc. are constituted, and hexagon shaft section 4111 is welded on the left and right sides of bar portion 411, anti-limited block 5, pedal position
413 and crank 412 ecto-entad is welded in bar portion 411 successively, it is and symmetrical.Locked by way of trampling pedal position 413
Control castor 2 and aviation castor 3 in fixed, and the scope of activities of treadle 41 is limited by anti-limited block 5 and service brake limited block 6
System, it is ensured that foot-operated brake mechanism 100 stuck situation occurs using safe and anti-locking mechanism.
Switching metal plate 42 is mainly used in realizing the locking to aviation castor 3, is provided with the front position of switching metal plate 42
Raised 421.
Aviation castor 3 and middle control castor 2 are arranged in the front and rear both sides on chassis 11, and aviation castor 3 can be by extruding
The spring 31 of vertical direction realizes that locking, middle control castor 2 control castor in being driven by such as hexagon ring of the axis hole 211 in the middle of rotation
Brake cam mechanism inside 2 realizes locking, is partially placed into the lower positions such as sick bed to meet some device bottom needs
Portion, front and rear two size of wheel needs inconsistent, that is to say, that the size of aviation castor 3 and middle control castor 2 can be with unequal.
Castor 2 is controlled in being locked by way of trampling pedal position 413, is using the mode reality for rotating hexagon shaft section 4111
It is existing.Hexagon shaft section 4111 is welded on the left and right sides of pedal position 413, and with such as hexagon ring pair of axis hole 211 of middle control castor 2
Neat then to insert middle control castor 2, trampling pedal position 413 makes hexagon shaft section 4111 control castor 2 in being locked by rotating.
Aviation castor 3 is locked by way of trampling pedal position 413, is realized using linkage.On treadle 41
Crank 412 is welded on the both sides of pedal position 413 (inner side of such as U-tube), and switching metal plate 42 is connected by pin and crank 412,
Similar to slider-crank mechanism, when depressing pedal position 413 and hexagon shaft section 4111 is rotated relative to axis hole 211, branch is being oriented to
Metal plate 42 of being transferred under the limitation of such as fastener of support member 422 can be slided (for example slide along the longitudinal direction) in guide support 422,
When pedal position 413 is floored (extreme position), on switching metal plate 42 raised 421 just withstand the spring on aviation castor 3
31 lock aviation castor 3.
The scope of activities of treadle 41 is limited by anti-limited block 5 and service brake limited block 6, refers to being welded on pedal position
Anti- limited block 5 on 413 and the polyurethane service brake limited block being fixed on anti-limited block 6 can be by mechanical position limitations to treadle
41 scope of activities is limited, it is ensured that foot-operated brake mechanism 100 is using safety and to prevent foot-operated brake mechanism 100 from occurring stuck
Situation.
Foot-operated brake mechanism 100 according to the utility model embodiment, using treadle 41 and simple linkage, realizes
Locking to equipment whole castors, and suitable for the inconsistent situation of castor size.Compared with traditional braking mechanism, the machine
Structure is simple to operation, it is to avoid the inconvenience of locked castor is separated, while meet some device bottoms to need to be partially placed into sick bed
Deng lower position inside when the inconsistent situation of castor size.The mechanism employs mechanical position limitation simultaneously, greatly improves peace
Full property and the reliability for using.
The castor mentioned in the utility model is not limited only to middle control castor and aviation castor, and all can be turned by central shaft
The castor of dynamic locking all can be considered middle control castor, and all castors that can be locked by compressing uprighting spring are considered as aviation castor.
The utility model is not only applicable to medical industry, and all can be adapted to mechanism enters line-locked equipment and be equal to the machine

(extreme position), raised 421 springs 31 just withstood on aviation castor 3 on switching metal plate 42 lock aviation castor 3.
Fig. 9 and Figure 10 show mechanical stop limiter, by anti-limited block 5 and service brake limited block 6 to the movable model of treadle 41
Enclose and limited, the anti-limited block 5 being welded on pedal position 413 and the polyurethane service brake being fixed on anti-limited block 6 are spacing
Block can be limited the scope of activities of treadle 41 by mechanical position limitation, it is ensured that foot-operated brake mechanism 100 is using safety and prevents
Only there is stuck situation in foot-operated brake mechanism 100.
Describe the work of the foot-operated brake mechanism 100 according to the utility model embodiment in detail with reference to Fig. 1 to Figure 10
Process.
Foot-operated brake mechanism 100 according to the utility model embodiment, when treadle 41 is located at the locked position in locking
Control castor 2 simultaneously drives the switching locking aviation of metal plate 42 castor 3, and castor 2 is controlled simultaneously in release when treadle 41 is located at the off-position
Switching metal plate 42 is set to discharge aviation castor 3.
Specifically, when treadle 41 (such as pedal position 413) is stepped on, bar portion 411 can rotate with shaft hole 211, pass through
The brake cam further locks middle control castor 2；At the same time, switching metal plate 42 is connected by pin and crank 412, class
Slider-crank mechanism is similar to, when the drive rotation of bar portion 411 of treadle 41 is stepped on, switching metal plate 42 can be relative to guide support
422 forward slips along the longitudinal direction, the locking aviation castor 3 when raised 421 press with spring 31；When projection 421 and spring 31
Aviation castor 3 is discharged when staggering.Locked while castor 2 and aviation castor 3 are controlled in can so realizing.Unclamp (the example of treadle 41
Such as pedal position 413) be to be discharged while being capable of achieving centering control castor 2 and aviation castor 3, release process with locking process conversely,
Will not be repeated here.Thus, locked while being easily achieved centering control castor 2 and aviation castor 3 by latch assembly 4 and released
Put, it is easy to operate and easily controllable.
In addition, by setting stopping means on foot-operated brake mechanism 100, the stopping means includes：The He of anti-limited block 5
Multiple service brake limited blocks 6, can be while realizing limiting the scope of activities of treadle 41, the security that raising is used.Extremely
This completes the course of work of the foot-operated brake mechanism 100 according to the utility model embodiment.
