Description

A kind of folder

Affiliated technical field:

The utility model relates to the folder of a kind of folding bicycle or mother and sons' car, doll carriage, wheelchair, motion or tourism supplies

Background technology:

Folder relatively is widely used on bicycle or wheelchair, tourism and the sports equipment at present.By the fast folding of folder, can significantly reduce the parking space of equipment, be easy to carry; Therefore its range of use constantly enlarges.

Common folder structure as shown in Figure 1, first folded piece 01 and second folded piece 03 of this folder are through at bearing pin 02 altogether, and can rotate around bearing pin 02.When first folded piece 01 and second folded piece 03 merge, utilize quick detach 04 on bearing pin 02 opposite with their locking, connected piece is in work or running condition (as Fig. 1 a); If in the time of will be with its folding, must earlier quick detach 04 be unclamped and leave second folded piece 03 (as Fig. 1 b), then first folded piece 01 and second folded piece 03 are turned to state shown in (Fig. 1 c) around bearing pin 02, lacked much than the state shown in Fig. 1 a like this, be convenient to collection and carry.Present this folder is widely used on the folding bicycle.

Along with becoming increasingly abundant of people life, not only to folding bicycle, foldable wheelchair has bigger demand, and the sports equipment of some portable bands and tourism supplies are also extensively liked by people gradually, for folder provides development prospect widely.Folder provided by the utility model is compared with traditional folder, and is not only simple in structure, good looking appearance, and have very failure-free safety, and be not only applicable to folding bicycle, also be applicable to other many fields simultaneously.

Summary of the invention:

Main structure body of the present utility model is a male member and a female part that cooperatively interacts; An and quick detach bolt group.

The shape of male member 05 (as Fig. 2), its head are the flat body that stretches out, and also have the cylinder of a projection at the head end of this flat body, in the root both sides of flat body one groove are arranged respectively; There is an elongated hole to run through flat body, and one counterbore arranged in addition at an end of elongated hole.

The head of female part 06 is as a fork-shaped (as Fig. 3), and it has the outside groove of an opening, and the flat body thickness and the shape of this groove and male member 05 match.Head at two fork sheets respectively has a projection, in the bottom of groove one counterbore or through hole is arranged; On two fork sheets the through hole of an axis normal in the groove plane arranged respectively, this two through hole is coaxial, in the outside in hole one counterbore is arranged respectively.

Quick detach bolt 07 is common locking mechanism commonly used, but its difference is the bottom of sliding sleeve 08 depression is arranged, and deposit a spring 09 in the depression, and a boss (as Fig. 4) is with in the inboard of its nut 10.

The utility model unitized construction such as Fig. 5.The flat body of male member 05 places among the groove of female part 06, and the cylinder of the outstanding flat body head of male member 05 is inserted in the hole of bottom portion of groove of female part 06, and simultaneously, the projection of 06 liang of fork of female part sheet head end is inserted in the groove of male member 05 flat body root; Quick detach bolt group 07 from 06 liang of female part fork sheet two holes and the elongated hole on the male member 05 flat body run through and mistake, under quick detach bolt 07 locking state, spring 09 is compressed, and the boss of nut 10 inboards passes female part 06 fork sheet on one side, is deep in the counterbore on the flat body of male member 05.

Under the situation that quick detach bolt 07 unclamps, because the effect of spring 09, quick detach bolt 07 whole the group by bullet to right-hand, the boss of nut 10 inboards still is in the counterbore on the flat body of male member, stop male member 05 to move up, the cylinder of the flat body head end of male member 05 remains in the hole of female part 06 bottom portion of groove, and the projection of female part 06 fork sheet head also remains in the groove on the male member 05, folder can not meet accident foldingly in the case, plays security insurance effect (as Fig. 6).

When needing to fold, must add a power P inwardly by the handle of quick detach bolt 07 with hand, spring 09 is compressed like this, nut 10 and quick detach bolt 07 are moved to the left together, make the boss of nut 10 inboards leave on the flat body of male member 05 counterbore (a) as Fig. 7, upwards lift male member 05 then, make the cylindrical body of the flat body head end of male member 05 leave the hole of concave body bottom portion of groove, the projection of female part 06 fork sheet head also leaves the groove (as Fig. 7 b) on the male member simultaneously, with the rotational of male member 05, finish folding (see figure 8) then around quick detach bolt 07.
