Abstract

The utility model discloses a handcart capable of climbing stairs. The utility model is composed of a wheel assembly of the handcart, and a handcart frame which is arranged on the wheel assembly of the handcart and is designed according to different purposes. The wheel assembly of the handcart is formed in the mode that the two ends of the wheel shaft of the handcart near to the shaft end point are respectively provided with strip-shaped wheel frames of the handcart which can be rotated round the wheel shaft of the handcart, the two ends of the wheel frame of the handcart are symmetrically provided with wheel shafts, handcart wheels are arranged on the wheel shafts, and the shaft ends of the wheel shaft of the handcart are separately provided with transitional wheels and the diameter of the transitional wheel is smaller than the diameter of the handcart wheel. The utility model overcomes the disadvantages of unstable operation, strong impact, and complicated track type structure of the planet wheeled type handcart existing in the prior art. The utility model has the advantages of simple structure, stable operation and convenient operation. Labor is saved.

Description

Handcart cabable for climbing stairs

The utility model relates to a kind of hand barrow, especially a kind of hand barrow of energy stair climbing.

Known to the contriver, existing hand barrow, baggage car that can stair climbing mainly contain with Chinese patent 90210130.7 and are the planet gear type structure of representative and are the track structure of representative with Chinese patent 90209459.9.

Chinese patent 90210130.7 disclosed " planet gear type is stepped on the building and made things convenient for car " adopts the planet gear type traveling gear, and is simple in structure, but operation is unstable, beats the operating difficulties effort during upper and lower stair; Chinese patent 90209459.9 disclosed " crawler type handcart capable of travelling up stairs " traveling gear mainly is made up of the crawler type crawl device, operate steadily, but complex structure, cost is higher.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provides a kind of simple in structure, operates steadily, easy to operate, laborsaving hand barrow that can stair climbing.

The purpose of this utility model can realize by following measure:

A kind of hand barrow of energy stair climbing, form with the vehicle frame that designs according to different purposes mounted thereto by wheel set, wheel set is near axial end the strip shape vehicle wheel frame that can rotate around axletree to be installed respectively at the axletree two ends, be symmetrically installed with wheel shaft at the vehicle wheel frame two ends, wheel is installed on the wheel shaft; Also be separately installed with the transition wheel of diameter at the axletree axle head less than wheel.

The utility model is in operation, and runs into obstacles such as similar stair, and front-wheel stops operating, because the effect of tractive force, wheel set is that central whole is stirred with the front wheel spindle, and transition wheel is when crossing the stair summit, can reduce resistance and tractive force, steadily finish the action of going upstairs; Transition wheel can reduce vibrations when going downstairs, and makes and operates steadily.

The utility model has following advantage compared to existing technology:

1, simple in structure, manufacturing is easy for installation, cost is low;

2, owing to adopt the transition wheel structure, make operate steadily, easy to operate, laborsaving.

The utility model accompanying drawing drawing is described as follows:

1-vehicle wheel frame 2-axletree 3-wheel shaft 4-wheel 5-transition axis

Fig. 2 is the lateral plan of Fig. 1

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, 2, by wheel set (1,2,3,4,5) and the vehicle frame that designs according to different purposes mounted thereto form can stair climbing hand barrow, wheel set (1,2,3,4,5) is near axial end the strip shape vehicle wheel frame (1) that can rotate around axletree (2) to be installed respectively at solid drawn pipe axletree (2) two ends, vehicle wheel frame (1) but the center bearing set; Be symmetrically installed with wheel shaft (3) at vehicle wheel frame (1) two ends, wheel shaft (3) can be selected the solid drawn pipe suit for use or be welded on the vehicle wheel frame (1), wheel shaft (3) is gone up wheel (4) is installed, also be separately installed with the transition wheel (5) of diameter at axletree (2) axle head, wheel (4) and transition wheel (5) cylindrical jacket rubber less than wheel (4).

Claims

1, a kind of hand barrow of energy stair climbing, form by wheel set (1,2,3,4,5) and vehicle frame mounted thereto, it is characterized in that: described wheel set (1,2,3,4,5) is near axial end the strip shape vehicle wheel frame (1) that can rotate around axletree (2) to be installed respectively at axletree (2) two ends, be symmetrically installed with wheel shaft (3) at vehicle wheel frame (1) two ends, wheel (4) is installed on the wheel shaft (3); Also be separately installed with the transition wheel (5) of diameter at axletree (2) axle head less than wheel (4).
