Abstract
The utility model relates to a folding mechanism. The folding mechanism is characterized in that one end of a screw bolt is connected with a pressing block; a lower connection plate connected with the pressing block is provided with a groove matched with the pressing block; a tensioning mechanism is arranged on the screw bolt, tenses the pressing block to press towards the lower connection plate; the tensioning mechanism comprises an eccentric handle 1, a pin shaft 2, a plastic pad 3, a spring 4, the screw bolts 5 and the pressing block 6. The folding mechanism has the advantages of simple mechanism, small size, low cost and convenient operation, and is mainly used for folding frames, folding handles, folding front forks, etc. on folding bicycles.
Description
The utility model relates to be mainly used in a kind of fold mechanism on the folding bicycle, and this fold mechanism can be applicable to folding stand, Foldable handlebar, folding front fork etc.
Existing be used in the quick-release bolt assembly that bicycle uses and be applied to fold mechanism, need to increase some auxiliary mechanisies, for example: anchor plate unloads the lateral support axle of bolt and support holes seat etc.These mechanisms are complicated, and size is big, and the cost height uses inconvenient.
The purpose of this utility model just provides that mechanism is simple, and size is little, and cost is low, a kind of fold mechanism easy to use.
Solution of the present utility model is such: have bolt, an end of bolt is connected with briquetting, and the other end passes upper connecting plate and eccentric handle is hinged, has and the matched groove of briquetting on the lower connecting plate that joins with briquetting; There is tensioner mechanism tension briquetting to press to lower connecting plate on the bolt.Turn on the groove that blocks lower connecting plate when briquetting, during with tensioner mechanism tension briquetting, upper and lower fishplate bar is pressed connection.When briquetting turned to the position that discharges lower connecting plate, upper and lower fishplate bar can separate.
The utility model has the advantages that mechanism is simple, size is little, and cost is low, and is easy to use.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is first kind of structural representation of the present utility model.
Accompanying drawing 2 is A-A cutaway views.
Accompanying drawing 3 is second kind of structural representation of the present utility model.
Accompanying drawing 4 is that K is to view.
The utility model includes eccentric handgrip 1, jointed shaft 2, plastic pad 3, spring 4, bolt 5, pressing plate 6, upper connecting plate 7, lower connecting plate 8, jointed shaft 9.
This mechanism has bolt 5, and an end of bolt 5 is connected with briquetting 6, and it is hinged with eccentric handle 1 that the other end passes upper connecting plate 7, has and briquetting 6 matched grooves on the lower connecting plate 8 that joins with briquetting 6; There is tensioner mechanism tension briquetting 6 to press to lower connecting plate 8 on the bolt 5.Described tensioner mechanism is meant the eccentric handle 1 that is hinged on bolt 5, and eccentric handle 1 is to be connected with plastic pad 3.On bolt 5, be connected with the spring 4 that briquetting 6 is outwards ejected.
In the present embodiment, described spring 4 is to be socketed on the bolt 5.In the structure shown in the accompanying drawing 2, the screw thread of described bolt 5 is and being threaded of briquetting 6; Jointed shaft 2 is to adopt rivet.In accompanying drawing 3 described structures, the screw thread of described bolt 5 is being threaded on the jointed shaft 2 with eccentric handle 1.Briquetting 6 connects as one with bolt 5.Briquetting 6 is strip shapes, and the width of briquetting 6 is slightly less than the width that clamps the position notch on the lower connecting plate 8, makes briquetting 6 can pass in and out this notch flexibly, and the length of briquetting 6 clamps the width of notch greater than lower connecting plate 8, and can be connected across the both sides of notch.
Principle of work of the present utility model is: jointed shaft 9 is active joint with upper connecting plate 7, lower connecting plate 8 are hinged, and tensioner mechanism includes eccentric handle 1, bearing pin 2, plastic pad 3, spring 4, bolt 5, briquetting 6.Locking operation is in proper order: eccentric handle 1 is upwards rotated, again eccentric handle 1 is rotated, drive briquetting 6 and turn to the notch that its narrow direction is aimed at lower connecting plate 8, upper and lower fishplate bar closes, make briquetting 6 reach the lower surface of lower connecting plate 8, rotate eccentric handle 1, drive briquetting 6 and rotate an angle, the notch both sides that make the long end bay of briquetting 6 receive lower connecting plate 8 as shown in Figure 4, rotate eccentric handle 1, the eccentric edge compressing plastic pad 3 of eccentric handle 1, jointed shaft 2 is moved up, and briquetting 6 is pressed to lower connecting plate 8, and upper and lower fishplate bar is clamped.The order of opening operation and locking reversed in order.
It is to be used to adjust the clamping degree that the utility model adopts the effect of bolt 5, during operation, with wrench operated briquetting 6, briquetting 6 is rotated with respect to eccentric handle 1, briquetting 6 will move to the desired position along bolt 5, add the elastic reaction of plastic pad, the clamping degree of mechanism is adjusted to required requirement.
