Description
Technical field
This utility model relates to a kind of castor lowering or hoisting gear and nursing bed.
Background technology
Nursing bed is one of the most common medical apparatus and instruments, numerous families also application more and more widely, become the common equipment of home care; Along with scientific and technological progress, the nursing bed structure is also continued to optimize and is upgraded, at present; Nursing bed is of a great variety, and its technology is also more and more ripe, yet; Existing all kinds of nursing bed majority improves the up-down of bed body, folding etc., and conventional art is but still adopted at the cabinet base position, and traditional cabinet base mainly contains two kinds; A kind of is to adopt fixing feet, and another kind is to adopt castor; Wherein, it is more steady to adopt the fixing feet mode that nursing bed is put, but it moves very inconvenience, can not move flexibly, needs manpower to remove, lift when moving, and causes and uses inconvenience; If adopt the castor mode; Then can move flexibly, but receive the influence of pulley rotating easily, it is not steady to cause nursing bed to be put; Easy generation is rocked; The effect of external force promptly possibly cause nursing bed integral body to be subjected to displacement a little, therefore easily result of use is produced harmful effect, and the device that does not have at present to make castor produce up-down is applied in nursing bed.
In sum, the nursing bed of prior art can not be taken into account and steadily put and move flexibly, has awkward technological deficiency.
The utility model content
This utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of castor lowering or hoisting gear that castor is gone up and down is provided.This utility model also provides a kind of nursing bed that comprises this castor lowering or hoisting gear, can make nursing bed move flexibly can stablize again and put, and result of use is better.
The technical scheme that the said castor lowering or hoisting gear of this utility model is adopted is: said castor lowering or hoisting gear comprises swivel joint and is installed in the castor of said swivel joint bottom; Said castor lowering or hoisting gear comprises that also lifting shaft, fixed hub, cross section are polygonal power transmission shaft, brake bar; Said power transmission shaft is horizontally through said fixed hub; Said brake bar and said power transmission shaft end secure fit; Said swivel joint top cooperates with said lifting shaft bottom is rotatable, and said lifting shaft stretches in the said fixed hub and said fixed hub clearance fit, and said fixed hub both sides are provided with the up-down driven unit; Said up-down driven unit comprises goods of furniture for display rather than for use, following goods of furniture for display rather than for use, connecting rod; The two side of said fixed hub has the up-down groove, and said connecting rod is horizontally through said lifting shaft and two ends and stretches out and is connected with said goods of furniture for display rather than for use down from the up-down groove of said fixed hub two side respectively, said on goods of furniture for display rather than for use one end and said power transmission shaft suitable; The other end and said goods of furniture for display rather than for use down flexibly connect; Said fixed hub outer wall secure fit has fixed support, and said fixed support is provided with limiting section, and the position that said upward goods of furniture for display rather than for use, following goods of furniture for display rather than for use flexibly connect is corresponding with said limiting section position.
Optimally, said castor lowering or hoisting gear also comprises the position limitation protection frame, the bottom secure fit of said position limitation protection frame and said lifting shaft.
Be fixed with some guide pillars on the said position limitation protection frame, fixed support is provided with some holes and said guide pillar is suitable, and said guide pillar periphery is combined with buffer spring, and said buffer spring is between said fixed support and said position limitation protection frame.
The technical scheme that nursing bed adopted that this utility model comprises said castor lowering or hoisting gear is: said nursing bed comprises a body, cabinet base support; Be provided with crane between said bed body and the said cabinet base support; Be installed with the feet of at least four hollow-core constructions on the said cabinet base support; Said castor lowering or hoisting gear is arranged on the inner space of said feet; The said fixed support in the said castor lowering or hoisting gear and the inwall of said feet are suitable and fixing, and said power transmission shaft passes said feet and is connected with said brake bar.
Said bed body all is equipped with head of a bed tailgate in two ends end to end, is provided with guardrail between the said head of a bed tailgate.
The bottom of said feet is equipped with anti-skidding cushion rubber.
The beneficial effect of this utility model is: said castor lowering or hoisting gear comprises that also lifting shaft, fixed hub, cross section are polygonal power transmission shaft, brake bar, fixed support, and in the time of need falling said castor, the application of force is depressed said brake bar; Said power transmission shaft then rotates; Drive simultaneously the last goods of furniture for display rather than for use of said fixed hub both sides and down goods of furniture for display rather than for use produce swing, and the said goods of furniture for display rather than for use of going up becomes greatly with angle between the following goods of furniture for display rather than for use, said connecting rod two ends receive said under the roof pressure effect of goods of furniture for display rather than for use; Up-down groove along said fixed hub moves downward; Thereby said lifting shaft is together moved downward, when the said connecting portion of going up goods of furniture for display rather than for use and following goods of furniture for display rather than for use moves to the limiting section that is provided with on the said fixed support, receive the barrier effect of said limiting section; The said goods of furniture for display rather than for use of going up then stops action with following goods of furniture for display rather than for use; And to said connecting rod maintenance roof pressure state, this moment, said lifting shaft dropped to enough distances, realized that thus said castor descends; The castor lowering or hoisting gear that this utility model provides can be controlled the lifting action of castor flexibly, and control procedure is convenient, fast.
In the said nursing bed of this utility model, be installed with the feet of at least four hollow-core constructions on the said cabinet base support, said castor lowering or hoisting gear is arranged on the inner space of said feet; The said fixed support in the said castor lowering or hoisting gear and the inwall of said feet are suitable and fixing, and said power transmission shaft passes said feet and is connected with said brake bar, when needs move nursing bed; To utilize said castor lowering or hoisting gear that said castor is fallen, and make said castor drop to the height that is lower than said feet, and utilize the limiting section that is provided with on the said fixed support to carry out spacing with following goods of furniture for display rather than for use the said goods of furniture for display rather than for use of going up; The decline state that keeps said castor, can easily move to desired location with nursing bed this moment, more laborsaving in the moving process, flexible; After nursing bed moved to desired location, be pulled upwardly said brake bar, said power transmission shaft reverse rotation; And drive said go up goods of furniture for display rather than for use and down goods of furniture for display rather than for use produce swing, and the said goods of furniture for display rather than for use of going up diminishes with angle between the following goods of furniture for display rather than for use, said connecting rod two ends receive said under the effect of goods of furniture for display rather than for use tractive; Up-down groove along said fixed hub moves upward, thereby said lifting shaft is together moved upward, and in the said fixed hub of retraction; Simultaneously said castor is upwards promoted; And in the said feet of retraction, at this moment, then play a supportive role by said feet; Support more steadily, avoid sliding.
