In the vertical respectively gripper shoe one that connects two correspondences of two sides in the lower surface of above-mentioned pedal 1, this gripper shoe one is the right-angled triangle plate body, its hypotenuse links to each other with the lower surface of pedal one, and this hypotenuse is identical with the long edge lengths of pedal one, the angle of the hypotenuse of described gripper shoe one and an angle A that right-angle side became is greater than the angle of the angle B that is become with another right-angle side, the right-angle side that forms angle A with hypotenuse is connected on the limit of pedal one, promptly the top on this limit is connected on the side of pedal one and epimere junction, and the angle of the angle A that above-mentioned hypotenuse and right-angle side form is generally 60 °.
The gripper shoe two that vertically connects two correspondences in the lower surface of pedal two near two sides respectively, described gripper shoe two is identical with the shape of gripper shoe one, be that gripper shoe two is the right-angled triangle plate body, its hypotenuse links to each other with the lower surface of pedal two, and this hypotenuse is identical with the long edge lengths of pedal two, the angle of the hypotenuse of gripper shoe two and an angle C that right-angle side became is greater than the angle of the angle D that is become with another right-angle side, the right-angle side that forms angle C with hypotenuse is connected on the limit of pedal two, and promptly the top on this limit is connected on the side of pedal two and epimere junction.
The hypotenuse of gripper shoe two equates with the angle A that right-angle side forms with gripper shoe one hypotenuse with the angle C that right-angle side forms.
For ease of depositing and taking care of, the distance between two gripper shoes one of above-mentioned pedal one lower surface is greater than the distance between two gripper shoes two of pedal two lower surfaces.
Pass through in the upper surface of pedal and epimere for ease of go-cart, avoid skidding, offer two chutes in the upper surface of two pedals and epimere, described chute is that the cross section is square slotted eye.
The utility model is to use like this:
This device is placed on the threshold, guarantee epimere be positioned at threshold directly over, two pedals are positioned at the both sides of threshold, the gripper shoe of pedal bottom plays the effect of supporting pedal, at this moment, the both sides of threshold form two gradients, and the user is when utilizing transported in hand truck fashion, trolley passes through threshold through pedal and epimere, and is very time saving and energy saving.When depositing, owing to be connected by rotatable mechanism between two pedals of this device and the epimere, can be with two pedal doublings, pedal one places the inside of pedal two, has reduced this device area occupied, is convenient to deposit.
The utlity model has following advantage:
(1) safe and reliable, be convenient to transportation.
(2) increase work efficiency, save the activity duration, reduce cost of transportation.
(3) be convenient to deposit and take care of installation, convenient disassembly.
(4) simple to operate, suitable application area is wide, is easy to promote, and cost of manufacture is low.
