Abstract
A kind of novel trilobed wheel with obstacle detouring that turns to.Mainly comprise 3 nylon and make 18 little drums on the face at bull wheel, each bull wheel edge and triangle frame.Bull wheel is combined by half wheel that two panels is identical, and with rivet together.There are 18 grooves at each bull wheel edge, often has a duct to be connected between adjacent two grooves.Little drum is arranged in the groove at bull wheel edge, is worn connect and be fixed in groove by a steel wire.Bull wheel edge curved surface given prominence to by little drum, to realize bull wheel cross motion, reduces the frictional failure of ground in the face of bull wheel simultaneously, increases the bull wheel life-span.3 bull wheels are arranged in a triangle frame by wheel shaft.
Description
(1) technical field
The utility model relates to a kind of novel trilobed wheel with obstacle detouring that turns to, and especially can realize cross motion.
(2) technical background
At present, the wheel that existing medical stretcher, perambulator etc. use is all less single wheel, and employs cardan wheel, makes car body be convenient to turn to.And some stretchers conveniently travel, its four wheels is all set to cardan wheel.But, when it is on unfairness ground or when running into step, just can not travels well, have a strong impact on efficiency.
The device such as existing baggage container on market, some is using trilobed wheel mechanism as its trailing wheel, though existing structure is convenient to travel on irregular ground or run in the step of square, they are not easy to cross motion, turn to comparatively difficulty.
(3) summary of the invention
The object of the present invention is to provide a kind of novel trilobed wheel with obstacle detouring that turns to, to solve general doll carriage, the wheel of the devices such as medical stretcher turns to inconvenient problem.
The utility model solves the technical scheme that its technical matters adopts: this invention primarily of: bull wheel, triangle frame, little drum, ring like steel wire, rivet, large wheel shaft, triangle frame adapter shaft are formed.Its bull wheel, little drum is formed by the machined manufacture of nylon material, and iron triangle frame, ring like steel wire, rivet are selected by market.It is characterized in that, the slightly outstanding bull wheel edge surface of little drum, can rotate along perpendicular to bull wheel working direction.
There are 18 grooves at described bull wheel edge, the little drum that 1 slightly protrudes from bull wheel edge surface is mounted with in each groove, a circular duct is had between every two adjacent grooves, wear to make steel wire the little drum connected in each groove and be fixed in groove, described steel wire is simultaneously as the rotating shaft of little drum, and little drum rotation direction is vertical with bull wheel rotation direction.Bull wheel forms after being assembled by 2 identical half wheels, 18 little drums and 1 ring like steel wire.
The profile of described half wheel is the half profile after being split into two halves by bull wheel from the center line of its edge surface by bull wheel, and uniform 3 through holes on described wheel, circle centre position through hole is for connecting bull wheel and triangle frame.
The wheel of described composition bull wheel has 3 circular holes, its effect be to provide synthesis bull wheel use the duct of rivet.
The little drum that the present invention installs on described bull wheel edge curved surface, makes described bull wheel realize transverse shifting.
The present invention can be applicable to, on perambulator, medical stretcher, baggage container, baggage car etc., be more convenient for turning to and obstacle detouring to make device, thus realizes pulsation-free motion more.
(4) accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of novel trilobed wheel integral structure schematic diagram with obstacle detouring that turns to.
Fig. 2 is each bull wheel structural representation in Fig. 1.
In figure: 1. little drum, 2. rivet, 3. bull wheel, 4. large wheel shaft, 5. tween drive shaft, 6. spider, 7. groove, 8. manhole, 9. ring like steel wire, 10. circular aperture, 11. half take turns, 12. rivet holes, 13. large axle holes.
(5) detailed description of the invention
Embodiment 1, see Fig. 1 ~ 2, the present embodiment provides a kind of novel trilobed wheel with obstacle detouring that turns to, and it comprises 3 bull wheels (3), 18 little drums (1) on each bull wheel, two iron spiders (6).Bull wheel (3) is arranged on three angles of triangle frame (6) by large wheel shaft (4), and can with it for axle rotates.Bull wheel (3) is by two half identical wheel (11) synthesis, and rivets with rivet (2).Triangle frame is synthesized by two identical spiders (6), and by tween drive shaft (5) and large wheel shaft (4) fixing.In motion, trilobed wheel has two bull wheels (3) and earth surface, realizes transverse shifting by little drum (1).
18 little drums (1) on described each bull wheel edge curved surface give prominence to bull wheel edge curved surface 1 ~ 2mm, the method of little drum shown in Fig. 1 is installed, its object is to: little drum can rotate in the direction perpendicular to bull wheel (3), when the device installing trilobed wheel needs to turn to, only device lateral need be pulled, little drum (1) will lateral rotation, easier realizes turning to make device.Simultaneously, because trilobed wheel longitudinally can only rely on bull wheel (3), realize with laterally relying on little drum (1) rolling, so when device is stopped at out-of-level ground, as long as setting device park posture, make little drum not identical with direction, slope with the rotating direction of bull wheel, device just can be stablized parked.
The edge of half wheel (11) of described composition bull wheel there are 18 grooves (7), when two identical half wheels (11) are combined, the groove (7) at wheel (11) edge forms 18 grooves, separately relatively to provide the installing space of little drum (1).
When the present invention uses, only with tween drive shaft (5) for axle, need be placed in operative installations, this novel turning to of installation can be made to realize better turning efficiency and obstacle climbing ability with the device of the trilobed wheel of obstacle detouring, and when parking, stability is also better simultaneously.
As shown in Fig. 1 ~ 2, be that more detailed explanation is done to the bull wheel in embodiment 1 and spider.The detailed construction of bull wheel (3) and little drum (1) is as Fig. 2, wherein, there is a circular aperture (10) in the middle of little drum (1), between 18 grooves (7) in wheel (13), have a circular hole slot (8) to be connected.When two identical half wheels (11) are combined, circular trough (8) between 18 grooves (7) in wheel (11) will form the circular duct that connects two grooves (7), there is a ring like steel wire (9), its radius is slightly less than the circular aperture (10) of little drum (1), ring like steel wire (9) is through the circular aperture of 18 little drums, little drum (1) is worn and links up, and little drum (1) is fixed in 18 grooves at edge through circular duct by ring like steel wire 9, little drum (1) can with steel wire (9) for axle rotates simultaneously.
The present invention can be applicable on the devices such as perambulator, medical stretcher, baggage container, shelf, and it can be more prone to more pulsation-free and realize turning to, and crosses over the obstacle of such as stairway step one class.
