Abstract

The utility model discloses a bicycle folder, comprising an upper folding bar, a lower folding bar and a folding mechanism, wherein the upper folding bar and the lower folding bar are hinged through a hinge mechanism. The bicycle folder is characterized in that the folding mechanism consists of a locking handle hinged on the upper folding bar, a semicircular clamping piece arranged on the lower folding bar and a handle safety locking buckle; a positioning plate is fixed in the locking handle, and is provided with an adjusting locking screw; a locking bolt for locking and adjusting the locking screw is arranged at one side of the positioning plate; the locking screw extends out of one side of the locking handle, and is locked by the handle safety locking buckle under a locking state; the semicircular clamping piece is arranged on a groove of a fixed block of the lower folding bar; a locking device is concealed in the locking handle to save space. The dual-locking structure ensures safer and more reliable use, and the bicycle folder can be widely applied in the field of bicycles.

Description

A kind of 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

At present, people's living standard is more and more higher, people are very high to the degree of utilization in living space, in order to save the space, conveniently deposit, the bicycle that the bicycle of integral type is folded type gradually replaces, and the bicycle of folded form mainly utilizes a bicycle folder with bicycle folding or open, folder becomes the longest and the easiest impaired parts of stressed time length in folding bicycle, the reasonableness of material, force structure can directly influence the service life of bicycle.

The folder of existing folding bicycle is made up of last folding, following two folded sheets and catch gear usually, upper and lower folded sheet is hinged with hinge, catch gear is installed on the folded sheet, on the following folded sheet adjust bar is installed, and adjust bar connects goes up folded sheet and catch gear; Constitute a four-bar mechanism by upper and lower folded sheet, adjust bar and catch gear, when two folded sheets folded into one, two folded sheets were locked; Such folder has the following disadvantages: one, catch gear is locked folded sheet by the dead point of four-bar mechanism, and there is fugitiveness in mechanism, and it is unreliable to work; Two, an adjust bar is set between folded sheet and the catch gear, under folded state, adjust bar still occupies certain space, the gathering of can not fitting fully; Three, the mechanism size structure motion theory of mechanics of folder is analyzed, discontinuity as can be known, and structure design is reasonable inadequately, causes the fracture damage of folder easily, the hidden danger that exists safe in utilization; Except that said structure, also have some simple folder, as direct folding fastener catch gear, common discontinuity, contraposition is inaccurate, damages easily, obviously the actual requirement of out of reach folding bicycle.

Summary of the invention

In order to overcome the deficiency of existing capability technology, the utility model provide a kind of locking firmly, reliable operation, the rational bicycle folder of foldable structure.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of bicycle folder comprises folding rod, following folding rod bar and fold mechanism, and described upward folding rod is hinged by linkage with following folding rod; It is characterized in that described fold mechanism is linked closely by the clamp handle that is articulated in folding rod, the semicircle Fastener that is installed on down folding rod and handle safety lock forms; Described clamp handle internal fixation installing and locating plate, the adjusting tie down screw is installed on the locating plate, being equipped with first of described locating plate is used to lock the lock bolt of regulating tie down screw, and lock bolt stretches out clamp handle first, and under locking state by the fastening of linking closely in the handle safety lock; Described semicircle Fastener is installed on down on the fixed block of folding rod.

The utility model further designs: be equipped with on the described fixed block and be used for positioning and locking handle dowel bolt; Described semicircle Fastener is provided with boss, and described with deciding the groove that piece is provided with ccontaining boss, described boss and groove are locked by fastening connection piece.

The beneficial effects of the utility model are: the utility model adopts installs the structure of regulating tie down screw in the clamp handle, regulate tie down screw and be clamped on the semicircle Fastener, and whole catch gear is hidden in the clamp handle, more saves the space, and simple in structure; Dowel bolt on the fixed block can make adjusting tie down screw and semicircle Fastener reach best gripping orientation, keeps reasonably from degree of tilt, and locking effect is more reliable; In addition, the handle safe locking is buckled further clamp handle, and the two-bolt lock locking structure is safety and reliability in use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the preferential embodiment of the utility model;

Fig. 2 is the structural representation after preferential embodiment folds;

Fig. 3 is the structure for amplifying scheme drawing of preferential embodiment clamp handle;

Fig. 4 is the structure for amplifying scheme drawing of preferential embodiment semicircle Fastener.

The specific embodiment

With reference to Fig. 1, Fig. 2, the preferential embodiment of a kind of bicycle folder comprises folding rod 1, following folding rod bar 2 and fold mechanism, and described upward folding rod 1 is hinged by linkage with following folding rod 2; Described fold mechanism is by the clamp handle 3 that is articulated in folding rod 1, the semicircle Fastener 4 that is installed on down folding rod 2, and the handle safety lock links closely and 5 forms.

The concrete once block construction of brief description: with reference to Fig. 3, described clamp handle 3 internal fixation installing and locating plates 31, described locating plate 31 is equipped with regulates tie down screw 32, being equipped with first of described locating plate 31 is used to lock the lock bolt 33 of regulating tie down screw 32, lock bolt 33 stretches out clamp handle 3 first, and under locking state by 5 fastenings of linking closely of handle safety lock.Described semicircle Fastener 4 is installed on down the same of folding rod 2 to be decided on the piece 21.Be equipped with on the described fixed block 21 and be used for positioning and locking handle 3 dowel bolts 22.Described handle safety lock links closely and 5 is installed on down on the folding rod 2, and the handle safety lock links closely 5 li and is provided with the clamping slot of the described adjusting lock bolt 33 of chucking.With reference to Fig. 4, described semicircle Fastener 4 is provided with boss 41, and described with deciding the groove that piece 21 is provided with ccontaining boss 41, described boss 41 is locked by fastening connection piece with groove.When described fold mechanism closes up; when rotating, clamp handle 3 downward folding rod 2 directions regulate the action that tie down screw 32 is prolonging the semicircular body track slip of semicircle Fastener 4; reach gripping orientation at last, the position of regulating tie down screw 32 reaches locking by dowel bolt 22 adjustings.

The beneficial effects of the utility model are: the utility model adopts the structure of regulating tie down screw 32 is installed in the clamp handle 3, regulating tie down screw 32 lock onto on the semicircle Fastener 4, whole catch gear is hidden in the clamp handle 3, more saves the space, and simple in structure; In addition, the handle safety lock 5 further clamp handles 3 that link closely, the two-bolt lock locking structure is safety and reliability in use.
