Detailed Description

The present invention will be further described with reference to fig. 1 to 3.

The utility model relates to a can fix small handcart of object, it includes backup pad 11, and two pull rods 12 have been arranged to the trailing flank of backup pad 11, and pull rod 12 is the telescopic link. Two wheels 13 are arranged on the rear side of the support plate 11, and the two wheels 13 are respectively arranged on the two pull rods 12. The small handcart has simple structure and small occupied space.

The front side of the supporting plate 11 is a carrying surface, and a plurality of anti-slip strips are arranged on the carrying surface. The anti-slip strip is made of carborundum materials.

In some embodiments, after the object is placed on the supporting plate 11, the supporting plate 11 is fastened by the binding band, and the binding band is fixed to the supporting plate by the binding object. The binding band is a common structure, and is not described in detail.

An inclined surface 16 is formed at the bottom end of the pull rod 12, when the pull rod 12 is erected, the inclined angle of the inclined surface 16 relative to the horizontal plane is 45 degrees, and the trolley can be conveniently inclined from the erected state after an object is fixed.

It should be noted that when the pull rod 12 is erected, the wheel 13 is separated from the ground by the support of the bottom end of the pull rod 12, that is, the height of the center of the wheel 13 should be greater than the radius of the wheel 13. In the process of inclining the small handcart, due to the action of the supporting plate 11 and the binding belt, the object and the supporting plate 11 are inclined simultaneously, the small handcart and the goods can be inclined continuously before the wheels 13 contact the ground, so that the resultant force of the normal force vertical component and the friction force vertical component is provided for the object by the object carrying surface of the supporting plate 11, the lifting force is increased continuously, and then the object is lifted off the ground; meanwhile, before the wheels 13 contact the ground, the lower end of the supporting plate 11 and a part of the object are always in contact with the ground, and due to the action of the binding belt, the object is prevented from slipping or falling due to insufficient lifting force or unstable support in the tilting process. With the continuous inclination of the supporting plate 11 and the object, the lifting force is formed by the resultant force of the normal force vertical component and the friction force vertical component, so that the lifting force is continuously lifted, and the object can be lifted off the ground finally.

The two pull rods 12 are respectively provided with a support rod 17, and the two support rods 17 are used for supporting the trolley when the trolley is horizontally placed.

Swing arm components are installed respectively to the left side and the right side of backup pad 11, and the swing arm component includes first swing arm 14 and second support arm 15, and the one end of first swing arm 14 is articulated with the side middle part of backup pad 11, and the other end of first swing arm 14 is articulated with second support arm 15, and the articulated shaft perpendicular to year thing face between first swing arm 14 and the backup pad 11, the articulated shaft of first swing arm 14 and second support arm 15 is along the length direction of its first swing arm 14 in place.

The swing arm members have a folded state in which the first swing arm 14 is rotated to the middle upper portion of the corresponding side and the second support arm 15 is rotated to the upper side of the support plate 11, and a support state. After the binding belt binds the object on the object carrying surface, the swing arm component can be adjusted to a supporting state. In the supporting state, the first swing arm 14 rotates to the middle-lower part of the corresponding side edge, the second support arm 15 rotates to the side where the object carrying surface is located, and the second support arm 15 is perpendicular to the object carrying surface, so that the second support arm 15 can support an object when the trolley is pushed and pulled.

The specific use of the dolly is as follows: the trolley is erected, the object is fastened on the object carrying surface through the binding belt, the trolley is inclined, and then the swing arm component is adjusted to be in a supporting state, so that the operation is simple and convenient, and the towing is convenient.

The bottom end of the pull rod 12 is designed to have an inclination angle, so that the rotating radius of the small trolley during the inclination is effectively reduced, and the force analysis shows that in the inclination process of the small trolley, the lifting force formed by the resultant force of the normal force vertical component and the friction force vertical component provided by the object carrying surface when the object is just inclined along with the support plate 11 is small, and at the moment, the object is easy to slide or slide from the object carrying surface, so that the rotating radius of the support plate 11 is reduced to reduce the initial sliding distance of the object, and a larger inclination angle is obtained, so that a larger lifting force is obtained.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
