Description

Bicycle folder

Affiliated field

The utility model relates to a kind of folder, especially for the folder of bicycle.

Technical background

Current, the folding of bicycle is by manufacturer's widespread use, and folding bicycle also is subjected to users to like that the bicycle folder technology reaches its maturity deeply, and style is various, competes more and more fierce.Make a general survey of existing bicycle folder, require existing safe and reliable structure, can operate convenient and simplely, also want simultaneously low cost of manufacture, elegant in appearance again, also out of reach far away.Therefore adopt new material, structure, design the bicycle folder that meets above-mentioned requirements, could improve its market competitiveness, satisfy people's demand.

Goal of the invention

The purpose of this utility model is to obtain a kind of reliable, with low cost, brief generous bicycle folder that uses.

Summary of the invention

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

A kind of bicycle folder, folder body before including, back folder body, hinge, pull bar, handle hinge, folder handle, to lock shaft, to lock screw, lock shaft, hinge support; Wherein, one end of preceding folder body passes through the lock shaft twisting with an end of back folder body, pull bar one end is hinged with the hinge support of the other end of back folder body by hinge, and the pull bar other end is hinged by handle hinge and handle, is provided with lock shaft in the handle.By handle, handle hinge and lock shaft combination, form the eccentric wheel (or adjustable type cam) of an adjustable eccentric distance.

The purpose of this utility model can also reach by following measure:

Lock shaft is provided with the lock screw, and preceding folder body, the back folder body twisting with bicycle folder becomes a pair of hinge reliably; The lock shaft that is installed in the handle adopts the mode that is threaded, and passes the pin jointed end of handle and pull bar and stretch out in handle, and the lock shaft outside face can be a screw rod, also can be screw thread; Handle can adopt plastic handle, and particularly adopting has engineering plastics suitable intensity, that be easy to be shaped to make, and can reduce production costs significantly, and leftover bits are few again, and yield rate is high again.

Bicycle folder of the present utility model, can be operated again at existing safe and reliable structure convenient and simplely, particularly adopts new material, structure, reduced manufacturing cost significantly, and elegant in appearance, can satisfy people's demand, have the cooresponding market competitiveness again.

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

Accompanying drawing 2 is assembling exploded views of the present utility model.

Accompanying drawing 3 is cutaway views of the present utility model.

Accompanying drawing 4 is the utility model folding process scheme drawings.

Accompanying drawing indicates explanation: preceding folder body 1, and back folder body 2, hinge 3, pull bar 4, handle hinge 5, folder handle 6 is to lock shaft 7, to lock screw 8, lock shaft 9, hinge support 10.

Specific embodiment:

Further set forth the utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is that preceding folder body 1, the back folder body 2 that will shape pass through lock screw 8 twistings; One end of pull bar 4 is hinged on by hinge 3 on the articulated stand 10 of back folder body 2 one ends, and the other end is then hinged by handle hinge 5 and folder handle 6; The lock shaft 9 that is installed in the folder handle 6 is threaded, and can be screw rod also, rotates through handle hinge 5, can hold out against the free end at back folder body 2 during locking, and the size of coupling mechanism force can be undertaken by the external part length of adjusting lock shaft 9.In fact, folder handle 6, handle hinge 3 and lock shaft 9 combinations, the eccentric wheel or the adjustable type cam of an adjustable eccentric distance of formation.Folder handle 6 adopts plastic materials, has certain suppleness, compares the metal handle, can be more easily and the Handle axis interference fit, and processing and manufacturing is easy, and cost is low.

More piece rod of likeness in form when bicycle folder of the present utility model launches, when using, forward and backward folder body is clamped in the bicycle folding place, folder handle 6 drives pull bar, the free end of preceding folder body 1 and back folder body 2 is locked together, just as fasten a stirrup to the bicycle folding place.Reliable for guaranteeing, the utility model has adopted two connecting rods to clamp self-locking structure, by the interference fit of handle hole and lock shaft, has played the locking function of lock shaft stop effectively, can carry out folding operation easily again.The engineering plastics of gorgeous colorful and difficult transformation color add much beauty to for the utility model again.

Be described in detail although it is pointed out that right the utility model here, with regard to this area staff, the similar modification of the class Sihe of making on this basis all should belong to protection domain of the present utility model.
