For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
As shown in Figures 1 to 5, hospital bed brake device for caster provided in this embodiment, comprising: castor 1 and arrestment mechanism 2,
The castor 1 is similar to the Castor structure of conventional hospital bed I, is made of idler wheel 11 and roller mount 12, is installed to disease by roller mount 12
Bed I leg on, it can be achieved that universal rotational, the difference is that the roller mount of the more conventional castor of roller mount 12 in the present embodiment
It grows, arrestment mechanism 2 is to be mounted in the roller mount 12 of 11 top of idler wheel, to brake to idler wheel 11.
Referring to Fig. 1 to Fig. 4, arrestment mechanism 2 includes: arrester hook 21, slide bar 22 and tension spring 23；Arrester hook 21 is by being connected to one
The crook 211 and lever portion 212 risen forms, and a side of crook 211 is recessed with the groove 213 being adapted to idler wheel 11, should
213 energy semi-surrounding idler wheel 11 of groove, lever portion 212 is connected to the upper end of crook 211 and extends outwardly from 213 side of groove,
The connecting portion of crook 211 and lever portion 212 is articulated in the roller mount 12 of 11 top of idler wheel, makes crook 211 with groove
The side of idler wheel 11 is arranged in 213 postures towards idler wheel 11；The slidable level of slide bar 22 is plugged in 21 top of arrester hook
In roller mount 12, and slide bar 22 is vertical with the axis of idler wheel 11；
It needs to guarantee simultaneously, when lift makes the circumference contact of the groove 213 of crook 211 and idler wheel 11 in lever portion 212, hook
The lowest point in shape portion 211 is flat not higher than the lowest point of idler wheel 11, to guarantee that the lowest point of crook 211 can be with ground face contact；And
When the pushing of lever portion 212 separates the groove 213 of crook 211 with idler wheel 11, the lowest point of crook 211 need to be higher than idler wheel 11
Lowest point, guarantee that the arrester hook 21 of discrete state will not influence the normal rolling of idler wheel 11.One end of tension spring 23 is connected to system
The end of the lever portion 212 of dynamic hook 21, the other end of tension spring 23 are fixed on the slide bar 22 of 212 extending direction side of lever portion,
On the slide bar 22 that is to say the top of idler wheel 11 far from 211 side of crook, so it is interior push away or draw outside slide bar 22, tension spring can be passed through
23 affect the lever portion 212 of arrester hook 21, and the crook 211 for agitating arrester hook 21 is separated or contacted with idler wheel 11.
In the present embodiment, above-mentioned arrestment mechanism 2 is respectively arranged one on two castors 1 of the same end hospital bed I, and will
The outer end of the slide bar 22 of two arrestment mechanisms 2 is connected by connecting rod 24, and then realizes that two-wheeled is braked simultaneously, increases the reliable of braking
Property；And pass through the connection of connecting rod 24, make to rotate with two castors 1 held with synchronous communicating, the movement and steering of hospital bed I is more
Add smooth；To the automatic of arrestment mechanism 2 and unlock operation, user inwardly pushes with foot or ticks outward connecting rod 24 can be real
Existing, the operation of braking and unlock is more convenient.
Above-mentioned hospital bed brake device for caster, when pushing slide bar 22 to the inside of hospital bed I, referring to Fig. 3, the drawing of slide bar 22 is drawn
Spring 23 makes to pull down shifting outside the lever portion 212 of arrester hook 21, and then crook 211 raises up and separates its groove 213 with idler wheel 11, makes
Castor 1 is in free state, does not influence the movement of hospital bed I.When hospital bed I needs fixed placement, referring to fig. 4, along the outside of hospital bed I
Direction pulls slide bar 22, and the upper fixed point of tension spring 23 is moved to the upper of 212 end of lever portion to the direction close to lever portion 212
Side, makes lever portion 212 raise up, and agitates crook 211 and moves down the circumference contact until groove 213 and idler wheel 11, to idler wheel 11
The friction catch of contact is formed, meanwhile, the lower end of crook 211 and ground face contact, by being in rolling contact for hospital bed I supporting leg and ground
It is converted into plane friction contact, hospital bed I stabilization is placed on fixed position.Above-mentioned 2 structure of arrestment mechanism is simple, does not have
Vulnerable part and frictional dissipation part, by the way of purely mechanic braking, braking is reliable, and can keep flexibly braking for a long time reliable
State；And the operation of braking and unlock, it can be achieved with by simply pushing and pulling slide bar 22, it is easy to use.
Referring to fig. 2 and Fig. 5, in the present embodiment, elasticity adjusting mechanism 3 is also provided in roller mount 12, the elastic adjusting
Mechanism 3 includes: friction member 31 and adjusting screw rod 32；As shown in figure 5, a cavity 121 is set in the roller mount 12 of 22 side of slide bar,
Friction member 31 is movably placed in the cavity 121, and adjusting screw rod 32 is bolted in cavity 121 in the roller mount 12 in outside, makes to adjust
The inner end of section screw rod spiral shell 32 can be projected into cavity 121 to be contacted with friction member 21, and handwheel 33 is arranged in the outer end of adjusting screw rod 32, with
Just adjusting screw rod 32 is rotated.
Above-mentioned elasticity adjusting mechanism 3 is set, the adjustable friction member 31 of rotation adjusting screw rod 32 and slide bar 22 are passed through
Contact pressure, and then dynamics needed for adjusting sliding slide bar 22, guarantee that slide bar 22 cannot be in the bullet of tension spring 23 in no external force state
Power lower slider guarantees that arrestment mechanism 2 keeps the braking or unlocked state that are formed under operator's external force, arrestment mechanism for a long time
2 movement is relatively reliable.In this implementation, elasticity adjusting mechanism 3 is respectively arranged one in the outside of two sides castor 1, two o'clock is simultaneously
The enabling power that the sliding of slide bar 22 needs is controlled, the movement of arrestment mechanism 2 is relatively reliable.
In conclusion hospital bed brake device for caster by adopting the above technical scheme, can keep for a long time to castor braking
Reliability, and it is easy to use.
