Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1; a kind of castor of medical hospital bed go-cart; comprise two wheel hubs 2, be arranged on the tire 3 of each wheel hub periphery, cover over cap 1 simultaneously outside wheel hub described in each; described two wheel hubs 2 are separately positioned on the left and right sides of trundle bracket by rotation shaft of wheel; described trundle bracket is provided with registration device, and described registration device is for adjusting the rolling orientation of wheel hub and only stopping of wheel hub.Described trundle bracket is provided with permanent seat and tight pulley 4, described permanent seat inner hollow, described permanent seat is one-body molded to be arranged on described tight pulley 4, described registration device comprises locating bush, rotating shaft 7, adjustment sheet 11, the second positioning teeth 6 being set in the first positioning teeth 8 in rotating shaft and being set on the first positioning teeth 8, permanent seat inside is stretched in described rotating shaft 7 lower end, ball is provided with between described rotating shaft 7 lower end base and described permanent seat interior bottom portion, arranging of this ball facilitates wheel to carry out 360 degree of rotations, described first positioning teeth 8 upper end is provided with 8 teeth 17, these 8 teeth are 4 one group, often organize the both sides that tooth is located at the first positioning teeth 8 respectively, the longer intervallum in one end is provided with between two groups of teeth, this intervallum will be longer than the spacing between each tooth, the teeth groove coordinated with described first positioning teeth 8 upper end is provided with inside described second positioning teeth 6, the teeth groove of described second positioning teeth 6 inside is provided with 8, the left and right sides is evenly distributed to be respectively one group with 4 teeth groove, described often group between teeth groove is provided with lug boss, under the effect of intervallum and lug boss, make the tooth of the first positioning teeth 8 when 0 degree and 180 degree, just in time can fall into the teeth groove of the second positioning teeth 6, and in other angles, due under the effect of intervallum and lug boss, then cannot engage, the teeth groove 18 matched with described second positioning teeth is provided with inside described locating bush, the limited post 12 that described permanent seat inner upper end edge is provided with reset post 13 and matches with described second positioning teeth tooth mouth, wherein reset post 13 is plastic return post, be provided with 3 altogether, each reset post 13 arranges uniformly at upper end-face edge, limited post 12 is iron prop, be provided with 2 altogether, carry out near arrangement with two in reset post respectively, in another reset post side near arranging connecting portion 10 of only stopping, described reset post lower end arranges elastomeric element, such as spring etc., under this design, described adjustment sheet 11 is located at locating bush place and can be promoted described second positioning teeth 6 and moves up and down along described rotating shaft 7, because the second positioning teeth 6 is locked on the first positioning teeth 8, after described second positioning teeth 6 moves up, described locating bush can entangle described second positioning teeth, therefore adjustment sheet 11 one end upwards swings certain angle, adjustment sheet 11 other end then moves up one end distance, thus make the second positioning teeth 6 compressed under the effect of reset post 13, move up a bit of distance, spring now under reset post 13 is still in half compressive state, then Mobile sickbed is passed through, make castor at 0 degree or 180 degree of places, the teeth groove engagement of end tooth 17 and the second positioning teeth 6 on first positioning teeth 8, now under the effect of reset post 13, continue a bit of distance that moves up, spring this moment under reset post 13 is in and returns to form, the teeth groove 18 of locating bush and the tooth of the second positioning teeth 6 engage.
In order to realize only stopping to castor, in described wheel hub 2, wheel side is evenly provided with latch, described registration device also comprises joint pin 10 of only stopping, arc seesaw 9 and portion 19 of only stopping, described joint pin 10 of only stopping is located at described permanent seat inner upper end edge, little spring is provided with between one end of described only stop joint pin 10 and described arc seesaw 9, the other end of described arc seesaw 9 arranges portion 19 of only stopping, described portion 19 of only stopping is provided with the latch coordinated with described latch, now, when adjustment sheet 11 regulates downwards, then the second positioning teeth 6 moves down, thus compress joint pin 10 of only stopping, joint pin 10 of only stopping drives one end of described arc seesaw 9 to move down by spring, under the effect of described arc seesaw 9 other end lever mode, upwards lift, thus by the latch engagement of wheel side in the latch in portion of only stopping and wheel hub 2, thus achieve only stopping to castor, and now the limited post 12 of the tooth mouth of the second positioning teeth 6 clamps, thus realize the control of the left-right rotation of castor.Design of the present invention is not only applicable to manual shift castor, be more suitable for electronic mode to regulate, a steering wheel 15 is designed especially by castor upper end, steering wheel 15 is provided with fixed column 16, this fixed column 16 contacts with rotating shaft 7 through steering wheel 15, by control line 14 connection control steering wheel 15 thus the angular adjustment of realization to adjustment sheet 11.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered as in scope.
