Description

Be convenient to the hand barrow of topping bar

The utility model relates to a kind of hand barrow of topping bar of being convenient to, and belongs to the People-Powered Vehicle field.

At present, hand barrow of the prior art is various, but most of hand barrows all exist the inconvenient shortcoming of topping bar, though and some hand barrow the time has been considered the problem of topping bar in design, but owing to exist shortcomings such as the rigidity of complex structure, cost of manufacture height, whole car and stability is not all bad, so still can not satisfy in actual use, people's needs.

The purpose of this utility model is: the hand barrow of topping bar of being convenient to that a kind of simple in structure, car load good rigidly is provided.

The utility model is to constitute like this: it is by vehicle frame (1), handle (2), front vehicle wheel (3), rear wheel (4), bearing pin (5), locking sliding sleeve (6), travel(l)ing rest (8), rotating shaft (9), torque spring (10) is formed, rear wheel (4) is contained on the fixed support (7) on the vehicle frame (1), front vehicle wheel (3) is contained on the travel(l)ing rest (8) of vehicle frame (1) front end, travel(l)ing rest (8) is connected with vehicle frame (1) with rotating shaft (9), torque spring (10) is housed in rotating shaft (9), the two ends of torque spring (10) are stuck on vehicle frame (1) and the travel(l)ing rest (8), handle (2) is connected with vehicle frame (1) with bearing pin (5), locking sliding sleeve (6) is enclosed within that handle (2) is gone up and can goes up at handle (2) and slide, an end of locking sliding sleeve (6) can be inserted in that vehicle frame (1) is gone up and handle (2) bonded assembly straight-bar on.

The utility model compared with prior art, because what vehicle frame (1) adopted is integral structure, connecting portion at vehicle frame (1) and handle (2) has locking sliding sleeve (6) to be fixed, so have simple in structure, car load good rigidly and advantage such as good stability in use.During use, if top bar, earlier with front vehicle wheel (3) perk, at this moment because step is run into front vehicle wheel, travel(l)ing rest (8) can turn round after an angle makes front vehicle wheel (3) get out of the way step, effect travel(l)ing rest (8) by torque spring (10) is got back to original position again automatically, front vehicle wheel (3) just can be placed on the upper class step like this, pushes away the car step of just climbing again forward, and so forth, just can push away car has topped bar.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is that the A of accompanying drawing 1 is to the position enlarged diagram.

Embodiment of the present utility model: vehicle frame (1), handle (2), bearing pin (5), locking sliding sleeve (6), travel(l)ing rest (8), rotating shaft (9), all adopt steel to make, front vehicle wheel (3), rear wheel (4), torque spring (10) can adopt the finished product assembling of selling on the market, rear wheel (4) is contained on the fixed support (7) on the vehicle frame (1), front vehicle wheel (3) is contained on the travel(l)ing rest (8) of vehicle frame (1) front end, travel(l)ing rest (8) is connected with vehicle frame (1) with rotating shaft (9), in the rotating shaft (9) on two travel(l)ing rests (8), adorn a torque spring (10) respectively, the two ends of torque spring (10) are stuck on vehicle frame (1) and the travel(l)ing rest (8), handle (2) is connected with vehicle frame (1) with bearing pin (5), the sliding sleeve (6) that will lock is enclosed within on the handle (2), when making locking sliding sleeve (6), it can go up be slided at handle (2), and make the one end can be inserted in that vehicle frame (1) is gone up and handle (2) bonded assembly straight-bar on get final product.
