A brake mechanism is composed of a foot pedal, braking levers, braking connecting levers and casters, wherein the braking connecting levers are fixedly connected to a braking device for the casters; a parallel four-rod mechanism is composed of the braking connecting levers and the braking levers; the foot pedal is fixedly connected with the braking levers.
Description
Technical field
The utility model relates to a kind of sick bed castor brake system, refers to be used in a kind of sick bed castor brake system on the medical sick bed (braking described in the utility model comprises unclamping after castor brake and the castor braking) especially.
Background technology
In the prior art field, four bights are provided with four castors on the sick bed base, the castor place is provided with independent stop mechanism, when pressing down brake component, brake component contacts with brake hub on the castor, realizes braking function, when take-off the brake spare, the brake off state, this brake can only be carried out in that castor is other, and four castors can not synchronous brakings or are unclamped.The utility model provides a kind of later-model castor brake system, brake system in the field compared to existing technology, the utility model has realized that four castors brake simultaneously or unclamp simultaneously, stability and safety can improve greatly, and the supporting caster wheel of the utility model institute is cheaper than the supporting caster wheel cost of prior art field brake system institute, and structure is simpler.
The content of utility model
The utility model just provides a kind of castor brake system, and this castor brake system comprises can brake the brake system of four castors and the caster wheel brake equipment that matches with it simultaneously.
The utility model can be achieved by following scheme, and promptly a kind of sick bed castor brake system is characterized in that, comprises and can brake the brake system of four castors and supporting with it caster wheel simultaneously.
And stop mechanism is by foot-operated, brake lever, and brake connecting rod, castor are formed, and wherein brake connecting rod is to be connected in the castor brake gear, and brake connecting rod and brake lever are formed a parallelogram lindage, foot-operatedly are connected with brake lever.

The specific embodiment
The utility model 1 is realized by the following technical programs: the brake system (as shown in Figure 1) that can brake four wheels in a kind of novel sickbed castor brake system simultaneously is by foot-operated 22, brake lever 20, and brake connecting rod 21, castor 13 is formed.Wherein brake lever 20 is that the cross section is orthohexagonal hexagonal steel (seeing accompanying drawing 2), brake castor is provided with the castor brake equipment, as long as this brake equipment rotating certain angle, just can be castor 13 brakings (the castor braking principle is treated full and accurate explanation), the brake equipment that brake lever 20 connects on the castor, foot-operated 22 and brake lever 20 be that same axis is fixed, foot-operated 22 rotating certain angle, brake lever 20 is also with regard to rotating certain angle, brake lever 20 is rotated the brake equipment rotating certain angle that will drive castor 22, so just can realize braking function.Brake connecting rod 22 and brake lever 20 are formed a parallelogram lindage (seeing accompanying drawing 3), brake lever 20 is rotating certain angle under foot-operated 22 effect, just can be relayed on the another side caster wheel brake equipment by parallelogram lindage, be implemented in another side castor brake equipment rotating certain angle simultaneously, so just realized four castor synchronous brakings.
The utility model 2 is realized by the following technical programs: the full and accurate explanation of the castor brake apparatus that matches in a kind of novel sickbed castor brakes: the structure of castor brake apparatus (seeing accompanying drawing 4) is by 1: plastic solid reservation 2: eccentric 3: brake type cone 4: pressure spring 5: locking organizes 16: wheel axle 7: bearing 8: engaging tooth A 9: wheel frame 10: brake rim 11: eccentric arbor wheel 12: briquetting 13: wheel 14: skidding bar B 15: engaging tooth B 16: be welded and fixed seat 17: dome 18: locking organizes 2 19: skidding bar A forms. Wherein decentralizing device 2 and brake type awl 3 is mounted in plastics permanent seat 1, plastics permanent seat 1 is fixing with wheel axle 6 by locking group 15, drag bar A19 is mounted in wheel axle 6 the insides, engaging tooth A8 is cemented on the drag bar A19, wheel axle 6 and wheel frame 9 are fixed, welding permanent seat 16 is fixed equally with wheel frame 9, and engaging tooth B15 is fixed on the welding permanent seat 16.And drag bar B14 and drag bar A19 fix.Briquetting 12 and drag bar B14 fix, camshaft 11 and brake drum 10 are pivotallys attached, and brake drum 10 is mounted in wheel 13 inner chambers, and brake drum 10 inner chambers are equipped with brake rubber block.
The basic functional principle of castor brake equipment: the castor braking is made up of castor wheel shaft braking (seeing accompanying drawing 5) and castor wheel braking (seeing accompanying drawing 6).Braking of castor wheel shaft and castor wheel braking carry out synchronously.Brake lever 20 is connected with decentralizing device 2, when brake lever 20 rotating certain angle, decentralizing device 2 also rotates an angle immediately, the rotation of decentralizing device 2 just can be pushed certain distance to brake type awl 3, brake type awl 3 is a bonded assembly with drag bar A19, the awl of brake type like this 3 drives drag bar A19 and moves downward certain distance, and drag bar A19 and engaging tooth A8 fix, drag bar A19 just drives engaging tooth A8 and moves downward like this, reach the engaging tooth B15 that is fixed on the welding permanent seat 16 when engaging tooth A8 movement travel, engaging tooth A8 and engaging tooth B15 intermesh, so wheel axle 6 is braked.Drag bar A19 moves downward, drag bar B14 fixes with it, drag bar A19 drives drag bar B14 and moves downward, and briquetting 12 and braking brake bar B14 fix, same briquetting 12 also moves downward, and briquetting 12 and camshaft 11 are pivotallys attached, briquetting 12 can drive camshaft 11 rotating certain angle, camshaft 11 is pivotallys attached with brake drum 10, camshaft 11 rotating certain angle, the brake rubber block of brake drum 10 inner chambers just opens certain angle, increases wheel 13 inner chamber brake drums 10 and brake rubber block friction force, thereby reaches wheel 13 brakings.
