Abstract

The utility model discloses a folder and in particular relates to a folder for folding a bicycle. The folder consists of a handgrip, a folder front edge, and a folder back edge. The handgrip is connected with the folder front edge through a handgrip rotating shaft; the folder front edge and the folder back edge are connected through a pin and are respectively welded on the bicycle; and the abutted surfaces of the two edges of the folder are abutted curved surfaces. Through simple in structure, the folder realizes all the functions of other folders; the folder can reach the functions of aligning and automatically positioning through the finely abutted curved surfaces when the folder is locked; and the stresses in all the directions are evenly diffused and weakened, thus increasing the strength of the folder and prolonging the service life of the folder. Meanwhile, the interior structure is simplified, so the folder is easy to process and simple to install. A rolling roller shaft housing arranged on the handgrip reduces damping caused by interference clamping, so the folder is simple for an operator to operate and is energy-saving and good in hand sense.

Description

Bicycle folder

Technical field:

The utility model relates to a kind of folder, particularly a kind of folder that is used for folding bicycle.

Background technology:

Bicycle occupies very consequence as the main vehicle of China always in people's daily life, in recent years, in order to save the space, conveniently deposit, and the bicycle that the bicycle of integral type is folded type gradually replaces.The bicycle of folded form then mainly utilizes a bicycle folder with bicycle folding or open.Folder becomes stressed maximum in folding bicycle, the longest and requisite again parts of the easiest damage of stressed time length.Material, force structure rationally, the degree of stability when folder rotates, all determined life-span of folder even bicycle.

Folder on the existing folding bicycle, as ZL200720052616.9, by flype, following flype, folding shaft and folding rod on the folder are made up, last flype is hinged by folding shaft and following flype, the folding rod of the last flype other end forms open and close type with following flype and is connected, described folding rod surface is provided with the recessed rail of spiral, dumbbell bar and one shape pin, cooperates capacity eccentric bearing, helical orbit pin, L type block and the open pore of flype setting down; With singlehanded rotary handle folder is opened, only be needed during closed folder close up bicycle mutually and get final product, folder is self-locking immediately.Solved the problem that is subjected to force intensity big like this, but design too complex and cost are wayward.

Also have some simple and easy folder, add buckle lock structure then usually because unbalance stress or contraposition are forbidden very easily to damage the Expected Results that the out of reach folding bicycle needs as directly folding.

Summary of the invention:

A kind of folder that is used for folding bicycle that the utility model is invented in order to address the above problem just, convenience simple in structure and superimposed the time automatic capturing, self-orientation, guarantee stressed evenly and disperse, improve the life-span greatly.

The utility model is achieved through the following technical solutions: bicycle folder, constitute by handle, folder leading edge and folder trailing edge, handle links to each other with the folder leading edge by arm pivot post, the folder leading edge is connected by bearing pin with the folder trailing edge and is welded on respectively on the bicycle, and the binding face of folder two edge adopts application of a surface.

The application of a surface face of described folder is a protruding curved surface and folder trailing edge one a recessed curved surface on the folder leading edge.Two applying curved surfaces are accurate fits, and curved surface can also be taked many application of a surface.

Also be provided with a push rod on the described handle, push rod one end is fixed on the push rod anchor shaft on the handle, and the other end is connected with drum shaft; Also be provided with a rotatable roller sleeve on the drum shaft; But the drum shaft close-fitting is pressed in two lugs of setting of folder leading edge.

Described handle upper ejector pin and push rod anchor shaft one end are by being threaded.

The utility model has been realized other folder all functions by simple structure, and when tightly locking, folder can directly reach the function of centering, self-orientation by the applying curved surface that precision is fitted, what make all directions simultaneously is stressedly spread uniformly and is decayed, increased the intensity of folder, prolonged the service life of folder. simplified inner structure simultaneously and made forming work relatively easy, assembling is simple; The roller sleeve of the rolling that is provided with on the handle reduces interference and clamps the damping that causes, makes operating personal simple to operate laborsaving, and feel is good.

Description of drawings:

Fig. 1 is the structural representation under the utility model locking situation.

Fig. 2 is an exploded view of the present utility model.

Identifier declaration among the figure: handle 1, push rod anchor shaft 2, push rod 3, roller sleeve 4, drum shaft 5, arm pivot post 6, folder leading edge 7, folder trailing edge 8, bearing pin 9.

Specific embodiment:

As shown in Figure 1, the face bonding of folder leading edge 7 and folder trailing edge 8 is on the car pipe, and when folder was tightly locked, bearing pin 9 flush fits were pressed in the folder leading edge 7, and 8 of folder trailing edges can rotate around bearing pin 9.Arm pivot post 6 is a tight fit in the folder leading edge 7, and 1 on handle can rotate around arm pivot post 6.Drum shaft 5 flush fits are pressed in two lugs of folder leading edge 7, and roller sleeve 4 skies are enclosed within drum shaft 5 and can rotate.The slot tail that push rod 3 passes in the handle is fixed on the push rod anchor shaft 2 by screw thread.In the hole of push rod anchor shaft 2 empty insertion handles.

As shown in Figure 1 and Figure 2, the process of opening is: clickwise handle 1, then push rod 3 can slip over the surface of drum shaft 4.Will overcome arm pivot post 6, drum shaft 5, the push rod anchor shaft 2 interference power on a line time this moment, also be coupling mechanism force.When handle 1 is thrown off roller sleeve 4 fully, folder leading edge 7, folder trailing edge 8 just can be opened.

The process of locking is: left-hand revolution handle 1, then push rod 3 can slowly slip over the surface of roller sleeve 4.Push rod anchor shaft 2 and arm pivot post 6 and push rod anchor shaft 2 and drum shaft 5 range difference between the two can reduce gradually, and the distance when arm pivot post 6, drum shaft 5, push rod anchor shaft 2 are on a line is minimum, 4 pressure maximums of push rod 3 and roller sleeve.Interference power reduces when slipping over this, and push rod 3 is understood a recovery of elasticitys part and pinned folder leading edge 7 and can not open with folder trailing edge 8.

As shown in Figure 2, when folder leading edge 7 and folder trailing edge 8 fit, there is curved surface to position, guarantees that control position is correct at vertical and horizontal.Have curved surface to correct when simultaneously folder leading edge 7 has dislocation with folder trailing edge 8, have curved surface when stressed power can be decomposed, reduced power size, change power direction, make stressed evenly.Because curved surface location and the stressed inner structure of having simplified are more prone to processing.

Although it is to be noted here the utility model is described in detail and describes, concerning the art technology staff, the similar or similar replacement of doing on the utility model all should belong to protection domain of the present utility model.
