Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

See fig. 1 and 2. For simplicity, more than two components are numbered, and only one is indicated.

The utility model discloses a kerbstone trolley, which comprises a trolley body and a clamping mechanism;

the clamping mechanism comprises two clamping plates 1 and two clamping arms 2 which are hinged and connected through a hinge shaft 3 to form an X shape, the hinge shaft 3 is used as a boundary, the upper parts of the two clamping arms 2 are used as clamping handles 21, the lower parts of the two clamping arms 2 are used as clamping heads 22, the vehicle body is connected with a lever 6, and the clamping handles 21 of the two clamping arms 2 are connected to the front end of the lever 6 through lifting ropes 11;

the clamping heads 22 of the two clamping arms 2 are respectively composed of a transition section 221 and a clamping section 222 which are mutually connected into an L shape, and the two clamping plates 1 are respectively hinged on the clamping sections 222 of the clamping heads 22 of the two clamping arms 2.

The utility model clamps the curb through the clamping mechanism, lifts the curb through the lever, and realizes walking transportation through the vehicle body;

during the use, the chuck card of two arm lock is at the top of curb 18, then slowly press down the rear end of lever, the front end of lever is taking the lifting rope to rise like this, the clamp handle of two arm lock will be close to each other and shrink, and because two arm lock become the X-shaped articulated, the chuck of two arm lock also is close to each other and shrinks simultaneously like this, thereby can clip the curb, along with the curb leaves ground, the weight of curb turns into the static friction of splint with the curb surface, this static friction is enough to bear the weight of curb, it is very firm, push the automobile body at last, transport the assigned position with the curb, lift the rear end of lever again, fixture falls and can loosen the curb naturally.
