Abstract
A folding box for bike relates to a folding bike, particularly relating to the improvements for the folding device of the folding bike. An exterior box and an interior box of the folding box are connected by pins and a publicized quick release is arranged on the side wall of the interior box. A plurality of reinforced ribs and pins with springs stretching out to the opposite sides of the interior box are mounted on the interior wall of the interior box. During installation, the main tube of the frame should be cut off at a certain position to make the exterior surface of the interior and exterior box firmly connected with the end of the cut-off frame. When using, the operator can hold the frame with two hands to buckle the folding box and revolve the handle of the quick release to complete the installation of the folding box and the bike. The utility model is of simple structure, precise positioning of the pin, easy folding and installation operation as well as rapid, tightened and reliable lockup, which can reduce the size of the bike for the convenience of bringing and storage.
Description
Technical field
The utility model relates to a kind of to folding bicycle, particularly to folding the improvement of bicycle folding mechanism.
Background technology
Before the utility model is realized, because folding bicycle can fold, volume is dwindled greatly, and then the boot that can put into automobile carry, and well received.Though the fold mechanism of existing folding bicycle is fairly simple, more complicated operates.In the structure as shown in Figure 1, pin 1 is provided with boss 2, is provided with spring 4 between the reinforced rib 3 of inner box.The upper end of outer box is provided with the thin corresponding groove 5 of part with pin, and the diameter of this groove is greater than the diameter of thin part on the pin, less than the diameter of pin convex platform.When folded box was closed, direction was pinned pin in box, and the thin part of pin is snapped in the groove of outer box, and pin will be stuck in the groove under the pressure of spring, thereby closes folded box.When opening and folding of bicycle is installed, a hand that needs the operator buttress bicycle half in box, press pin, second half of another hand propelled bicycle, treat that folded box is closed after, the hand of pressing pin can unclamp.The said structure of background technology makes the operation of operator very inconvenient.
Technology contents
The purpose of this utility model is, by a kind of bicycle use folded box is provided, thereby actv. has solved the problem that exists in the above-mentioned background technology.
Technical solution of the present utility model is: be connected with pin between the outer box of folded box and the inner box, the side of inner box is provided with the quick detach in the known technology, the locating dowel pin that has spring that inside face is provided with reinforced rib and can be stuck in the relative both sides of inner box respectively.
Outer box upside is provided with and the corresponding groove of locating dowel pin, and the side is provided with and the corresponding groove of quick detach, and downside is provided with a locating plate with inclined surface, be provided with below the locating plate can with described locating dowel pin lower end corresponding positioning hole.
One end of described locating dowel pin is provided with handle, and the other end is semisphere, and centre portion passes the reinforced rib and the spring of inner box inside face.One end of described spring is supported on the back-up ring, and the other end is against the side of a reinforced rib.Another back-up ring is arranged at the another side of same reinforced rib.Described back-up ring all is fixed on the described pin.
During installation, the person in charge in position blocks with cycle frame, and the outside face of folded box inner box, outer box is captiveed joint with the end of cycle frame person in charge truncation part respectively.During use, only need to catch respectively the vehicle frame of bicycle with two hands, folded box is interlocked, pin will be under the combined action of locating plate inclined-plane and locating dowel pin upper spring, automatically insert in the knock hole, the screw portion of quick detach crouches in the groove of outer box side simultaneously, rotates the handle of quick detach then, quick detach is anchored on the side surface of outer box, can finishes the installation of folded box and bicycle.In the time of need folding, elder generation's rotation quick detach handle, to remove the fastening of the external box of quick detach, the simultaneously outside then handle that spurs locating dowel pin, one side is rotated the vehicle frame of bicycle, can open folded box, finishes the folding of bicycle.
Of the present utility model simple in structure, the locating dowel pin accurate positioning makes bicycle folding and fitting operation easy, and when locking is quick, fastening, reliable, can make the bicycle volume-diminished, and then easy to carry and store.
