Abstract

A handlebar folding device for bicycles comprises a left handlebar, a right handlebar, a middle seat, a connecting rod and a regulation screw, wherein a knob is arranged in front of the middle seat, a C-shaped sheet is driven through rotating the knob for pulling the connecting rod and a regulating screw rod to a locking position, and the connecting rod can be pushed away from a dead point through the C-shaped sheet when the knob is rotated towards the other direction, i.e. the handlebars can be folded.

Description

A kind of handgrip folder

Technical field

The utility model relates to the handgrip of a kind of bicycle or battery-driven car, three-wheel vehicle.

Background technology

Folding bicycle is easy to carry with it and saves the characteristics of parking space and be subjected to extensively liking of people.

Common folding bicycle is a folder to be installed the car beam is divided into two sections of front and back on the car beam, to reduce the length of bicycle; And a folder is installed on handle riser to reduce the height of bicycle.The folder of these two positions is used commonplacely, also comparative maturity.

But at some in particular cases, handgrip need be folded up, to reduce the width of bicycle; Still do not have ripe in the folding present industry to handgrip and desirable mode, common method such as Fig. 1 that adopts, there is a sleeve pipe 02 centre, and the driver inserts 01 and 04 from the two ends of sleeve pipe 02 respectively.Respectively establish a bullet pin 03 on handgrip, when

handgrip

01 and 04 was inserted into its fixed position, the bullet pin was in the knock hole of setting on the sleeve pipe, and handgrip comes off in the time of can preventing to ride.Must earlier bullet pin 03 be depressed when folding, then driver's handle be extracted out from sleeve pipe, as Fig. 2 (a); Between two

handgrips

01 and 02, link as the consequently folding defensive position of Fig. 2 (b) not coming off voluntarily with a tightrope 05.

This mode is simple in structure, but the action trouble is easily loosening.Use generally on Kickboard Scooter, some bicycles also have employing, but bicycle is to reduce to rock and at the two ends of sleeve pipe fluting and respectively add one group of fast disassembly type tube bank when adopting.Though reduced like this to rock, when folding action loaded down with trivial details, the aesthetic feeling of outward appearance is relatively poor, is difficult to promote.

Summary of the invention

In order to address the above problem, the utility model provides a kind of easy to operate, safe and reliable handgrip foldable structure.Its good rigidly, folding convenient, good looking appearance is generous.

Structure of the present utility model such as Fig. 3,

In seat 08 be a U-shaped spare, a pin-and-hole that runs through the U-shaped two sides is respectively arranged about it, wear a left bearing pin 07 and a right bearing pin 09 respectively; Left hand 06 and right handgrip 10 head connector positions a pin-and-hole is arranged near the position of above and below, left hand is connected 06 with middle 08 by left bearing pin 07, right handgrip 10 is connected with middle 08 by right bearing pin 09; Left hand is worn an adjusting screw(rod) 14 a pin 15 is arranged in the hole of 06 bottom in the cross-drilled hole on this pin; The hole of right handgrip bottom is connected with connecting rod 12 by pin 11; Link to each other with pin 13 between adjusting screw(rod) 14 and the connecting rod 12.Having in the middle of the adjusting screw(rod) 14 can be for the flat position of spanner clamping, and one on the screw thread at two is that left-handed other end is dextrorotation, and perhaps one is screw thread and the other end is a polished rod.

State shown in Figure 3 is the position that the utility model launches running condition.At this moment, adjusting screw(rod) 14 and the approximate straight line that is of the line at connecting rod 12 two ends, the seam of handgrip 06, handgrip 10 upper ends and middle seat 08 two ends push against mutually simultaneously, and two handgrips are stable not to have diastema, can not rock or rock very small.Both can change distance between pin 13 and the pin 15 by rotating adjusting screw(rod) 14, make when handgrip 06 and handgrip 08 top seam and middle 08 two ends push against, adjusting screw(rod) 14 is a straight line with connecting rod 12 end points lines, is positioned at " dead point " position, and two handgrip above-below directions all must not be taken action.

Desire is folding with two handgrips, the pin 13 that connects adjusting screw(rod) 14 and connecting rod 12 must be moved down, and makes adjusting screw(rod) 14 and connecting rod 12 become an angle by straight line, as Fig. 4 (a), both can easily two handgrips be folded into the state as Fig. 4 (b).

In Fig. 5, a bearing pin 16 is installed in a side of middle seat 08, and this bearing pin and screw 18 are fixed in knob 17 on the bearing pin 16 and can rotate around it; There is a pin 19 the off-center position on the knob 17, and pin also rotates around bearing pin 16 during turning knob.Respectively there is a hole at the position up and down of C matrix 20, and pin 19 is through in the hole of C shape sheet upper end, and pin 13 is through in the hole of C shape sheet lower end; By the adjusting of screw 21, when making pin 19 be positioned at first dead center, pin 13 just in time is positioned on the line of pin 11 and pin 15, makes mechanism be in safety position.During application of force turning knob 17, the position of pin 19 can be moved to (b) as Fig. 5 (a), (c); Simultaneously the position of pin 13 also can be made pin 13 become the position shown in (b) by the position shown in Fig. 7 (a) by to bottom offset, and

handgrip

06,10 just is easy to be folded into the position shown in Fig. 4 (b) downwards.Another side at middle seat 08 installation knob 17 is connected with vertical tube 23 by an extension pipe 22; Its outward appearance and operating process are: on the middle seat at two handgrips middle part a knob arranged, when to a direction turning knob, handgrip can be locked, when another one direction turning knob, then can untie locking, and handgrip is folding downwards.
