Description
Technical field
This utility model relates to medical bedstead field, particularly a kind of telescopic screw mandrel for medical bedstead rocking handle.
Background technology
Medical bedstead is the required instrument of hospital and home care patients and heavy patient, can shake, to facilitate the nursing to patient at an even a few place as required.Method conventional is at present one or two rocking handle of installation at medical bedstead, is rotated shaken position medical bedstead needing lift by rocking handle.But because rocking handle is in outside the head of a bed, nursing staff can be hindered to walk about, even can trip nursing staff.For this reason, usually rocking handle handle is made the form being flexibly connected and can turning back, the used time does not turn up, in order to avoid affect walking about of nursing staff.
Some problems are but with in this flexible connection, are first strength problems, because be flexibly connected, intensity is not enough; Secondly, often can turn back because have forgotten, by the various dolly that moves back and forth or personnel's damaged in collision; In addition, folding rocking handle pulls out or retraction repeatedly due to needs, easily causes occurring dislocation between rocking handle and bearing, affects work efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of and uses convenient, safe medical bedstead bidirectional protective telescopic screw rod.
This utility model solves the technical scheme that its technical problem adopts:
A kind of bidirectional protective telescopic screw rod of medical bedstead; comprise gangbar and expansion link successively; described gangbar is built-in with trapezoidal screw; described expansion link is built-in with polygonal rod; connected by universal joint between the rear end of described trapezoidal screw and the front end of polygonal rod; polished rod face place, described trapezoidal screw rear end is set with bearing spider, and the front-end and back-end inside described bearing spider are respectively provided with a bearing.
As a preference, described gangbar is built-in with screw mandrel swivel nut, the front-end and back-end of described screw mandrel swivel nut have the interlaced cotter way in position, spacer pin is provided with in described cotter way, spring is provided with between described spacer pin and cotter way, be positioned at screw mandrel swivel nut front place inside described gangbar and be provided with inner side limiting-position annulus, described inner side limiting-position annulus has gangbar groove towards cotter way side, described screw mandrel swivel nut rear is provided with screw mandrel spacing collar, and described screw mandrel spacing collar has screw mandrel stopper slot towards cotter way side.
As a preference, the front and back ends of described bearing spider is disposed with the spacing collar respectively, avoids misplacing between trapezoidal screw and bearing spider, being shifted.
As a preference, between described gangbar and bearing spider, be connected with the dust cover that can surround and block trapezoidal screw, avoid dust to enter.
As a preference, described polygonal rod is hexagonal rod.
The beneficial effects of the utility model are: the bidirectional protective telescopic screw rod of this medical bedstead is by rational structural improvement; particularly at the bearing that the front-end and back-end of bearing spider are arranged respectively; the intensity of rocking handle is not only improve by duplex bearing; and duplex bearing design can utilize the bearing of bearing spider front end to assist the active force born when rocking handle pulls out more; by the bearing of bearing spider rear end assist bear rocking handle retraction time active force; disperse the stressed of bearing; realize the effect of rotational structure bidirectional protective, improve rocking handle service life.

Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is axonometric chart of the present utility model;
Fig. 2 is partial sectional view of the present utility model;
Fig. 3 is part-structure exploded view of the present utility model;
Fig. 4 is the partial enlarged drawing in Fig. 2.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3; a bidirectional protective telescopic screw rod for medical bedstead, comprises gangbar 1 and expansion link 2 successively, and expansion link 2 is also connected with rocking bar union joint 3 and crank handle 4; wherein gangbar 1 links with the lifting mechanism of medical bedstead, and expansion link 2 is as the telescopic body of rocking handle.Described gangbar 1 is built-in with trapezoidal screw 5, and the middle of the trapezoidal screw 5 wherein in general rocking handle is flank, and the two ends of trapezoidal screw 5 are polished rod face.Described expansion link 2 is built-in with polygonal excellent 6, and wherein as a preference, described polygonal excellent 6 is hexagonal rod, and its transmission effect is better.Expansion link 2 and polygonal excellent 6, for being slidably connected, ensures that expansion link 2 can stretch out or retraction as required.Connected by universal joint 61 between the rear end of described trapezoidal screw 5 and the polygonal front end of excellent 6, make rocking handle collapsible.Polished rod face place, described trapezoidal screw 5 rear end is set with bearing spider 7, and the front-end and back-end inside described bearing spider 7 are respectively provided with a bearing 71, and the bearing arrangement of trapezoidal screw 5 designs for duplex bearing.The front and back ends of described bearing spider 7 is disposed with the spacing collar 72 respectively as auxiliary fixing structure, avoids misplacing between trapezoidal screw 5 and bearing spider 7, being shifted.Be connected with the dust cover 53 that can surround and block trapezoidal screw 5 between described gangbar 1 and bearing spider 7, avoiding dust to enter affects the work of trapezoidal screw 5.The tail end of trapezoidal screw 5 is connected with sealing ring 13 by 14 pins.
With reference to Fig. 2, Fig. 4, described gangbar 1 is built-in with screw mandrel swivel nut 8, the front-end and back-end of described screw mandrel swivel nut 8 have the interlaced cotter way in position 81, spacer pin 9 is provided with in described cotter way 81, spring 91 is provided with between described spacer pin 9 and cotter way 81, be positioned at screw mandrel swivel nut 8 front place inside described gangbar 1 and be provided with inner side limiting-position annulus 11, described inner side limiting-position annulus 11 has gangbar groove 12 towards cotter way 81 side, described screw mandrel swivel nut 8 rear is provided with screw mandrel spacing collar 51, described screw mandrel spacing collar 51 has screw mandrel stopper slot 52 towards cotter way 81 side.When trapezoidal screw 5 rotate to enough deeply make the cotter way 81 at two ends stick into gangbar groove 12 and screw mandrel stopper slot 52 respectively time; trapezoidal screw 5 just can not continue to rotate relative to gangbar 1; namely trapezoidal screw 5 just can directly drive gangbar 1 to rotate; so just play from position limitation protection effect, avoid trapezoidal screw 5 revolve dark and damage.And only need trapezoidal screw 5 to rotate backward to exit, screw mandrel spacing collar 51 is and then exited, until one of them cotter way 81 unclamps from cotter way 81 or gangbar groove 12, spacingly just can to remove.Said structure improves the protective effect to screw mandrel further.
According to above-mentioned principle, this utility model can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, this utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
