Abstract
The utility model discloses a stay rod type loading vehicle for traveling on land and up or down stairs. The lower part of the vehicle frame adjacent to the vehicle wheels is provided with a stay rod which can rotate around a stay rod shaft or along with the stay rod shaft; the upper end of the stay rod is circular arc shaped; the length of the circular arc approximately equals to the distance from the wheel shaft to the stay rod shaft; a stay rod rack is arranged on a same shaft with the frame, and can rotate around the shaft into the folding state.
Description
The utility model is a kind of loading hand barrow that is applicable to stair or level walking.
In the prior art, the stairs and flat land dual purpose dolly generally is to be provided with two starframes that can rotate around the axis below vehicle frame, be equipped with on each starframe three or four wheels (see US4312-417, GB2073-111, US4264-082).Rely on the rotation of starframe and wheel, dolly just can be gone up downstairs.When level walking, dolly need be provided with lockout mechanism and starframe be pinned motionless, otherwise four wheels contact with ground simultaneously, and car is difficult for turning to.This shows, this vehicle structure complexity, volume is big, and manufacturing cost is higher.
The purpose of this utility model is to design a kind of travelling in widespread use at present some auxiliary parts of increase on the dolly basis, just can realize the dual-purpose barrow of stair or level walking function, and possess simple in structure, low cost of manufacture, can folding etc. characteristics.
The utility model is provided with near the wheel place below vehicle frame can be around rotation of strut axle or the strut that rotates together with the strut axle.The strut axle parallels with axletree.The strut upper end is circular arc, and its circular arc length is approximately equal to axletree to the interaxle distance of strut.The strut axle is fixed on the strut frame.Strut frame and framework are contained on the same axis, and can rotate around it into the folding state.Strut frame and framework are respectively equipped with locating piece, and locating piece can make them perpendicular to vehicle frame, so that dolly stair activity and lade.
The utility model is easy to carry owing to simple in structure, easy to manufacture, and easy to use, cost is low, and good reliability is for the people's carrying heavy goods that inhabits in the high-rise of not establishing elevator provides convenience.
Fig. 1 is the structural representation of dolly;
Fig. 2 is a dolly folding constitution diagram.
Embodiment of the present utility model is: vehicle frame (14) below is provided with two struts (3), and the distance between two struts is greater than the distance between the wheel.Strut is arcuation, and its upper end fuses for circular arc and with strut axle (6), can rotate together thereupon.The strut axle is connected with strut frame (9) by pipe link (4).In order to change the distance between strut axle and the axletree, the displacement of strut axle can be paid (8) with the nut of strut frame and regulate.Strut frame (9), framework (12) are contained on the axle (18), and can rotate to it.Rely on locating piece (10), (11), strut frame, framework can be respectively perpendicular to vehicle frames.During the car folding, the strut frame rotates to the vehicle frame top together together with strut, and framework forwards near vehicle frame, and an end of rope (13) catches on the pin (2) of strut side, keeps the folding state of framework, strut frame and strut with this.The car bearing goods is when level walking, and framework should put down, and with locating piece (10) location, strut frame, strut still are in the folding state.When car is gone upstairs, put down strut in advance, make dolly be in strut preceding, wheel after situation, locating piece (11) makes strut frame and vehicle frame perpendicular.Destroy strut frame and the perpendicular phenomenon of vehicle frame for fear of deadweight, be provided with the elastic hook (17) that can block vehicle frame at the upside of baffle plate (11) because of strut frame and strut.When the strut head contacted the root of stairway step face, the step vertical surface stoped the strut head to move forward, because people's pulling force makes dolly and strut thereof rotate around strut head fulcrum, so dolly is propped up, its total weight moves to strut by wheel and bears.After dolly arrived vertex, second step horizontal surface of circular arc outside face and stair of strut upper end contacted, and under the effect of pulling force, rolls, and touches this step horizontal surface up to wheel.At this moment, dolly weight all moves to wheel, and the arc-shaped surface of strut upper end is left step surface, and dolly is just finished an action upstairs, and returns to initial condition, begins to prepare next action upstairs.
Dolly can be considered negative actuation upstairs downstairs, and at this moment, wheel is preceding, strut after.Impact when going downstairs step in order to reduce car, strut frame front end is provided with backing block (5).Strut headgear (1) is to make with rubber or plastics, to increase the friction coefficient of strut head, in case of necessity, places pad in the strut headgear, can regulate the length of strut within the specific limits.
Hook (16) is used for articulating carrying rack of bicycle, and dolly can be travelled with bicycle.Dolly also can be disposed across above the carrying rack of bicycle, is fixed with hook (15).Spur soft rope (20), two spring holders (21) are withdrawed from from knock hole, handle (22) just can rotate folding down around axle (19).
Claims (6)
1, a kind of stairs and flat land dual purpose dolly that is made of vehicle frame (14) framework (12) and wheel is characterized in that:
Place near wheel is provided with rotary strut (3),
Strut one end is a circular arc, and its circular arc length is approximately equal to the distance of strut axle (6) to axletree,
The strut axle parallels with axletree.
2, dolly according to claim 1, the strut frame (9), the framework (12) that it is characterized in that being respectively equipped with locating piece (11) (10) are contained on the same axis (18), and can rotate around it.
3,, it is characterized in that the nut that the strut frame is equipped with scalable strut displacement pays (8) according to claim 1,2 described dollies.
4, dolly according to claim 3 is characterized in that strut frame front end is provided with backing block (5).
5, according to claim 1,2 described dollies, it is characterized in that strut is arcuation, distance is greater than the distance between the wheel between the strut.
6, dolly according to claim 2 is characterized in that a side of strut frame locating piece (11) is provided with the elastic hook (17) that can block vehicle frame.
