Description
Technical field
The present invention relates to cycle arm, specifically, it is a kind of rotatable cycle arm assembly.
Background technology
Existing bicycle, the handle installing bicycle handle bar stands one end and connects firmly with handlebar, the other end and vertical tube of front fork screw
Fastening.There is a gland to push down vertical vertical upper end, in gland, have a screw to be connected with " heronsbill " nut in front fork, for adjusting
Front fork bowls group gap.
Because handlebar is vertical with frame, the front positioned at handlebar, the width of car load is exactly the length of handlebar for brake,
Take up space when depositing or packing larger.
Content of the invention
The technical problem to be solved is to provide the rotatable bicycle that a kind of structure is simple and convenient to operate
Vertical assembly, handlebar is made to can rotate to and vehicle body parallel, and the lower section rotation to handlebar of braking, thus greatly reducing car load
Width, is easy to deposit and packs.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of rotatable cycle arm group
Part, including the pipe spreader of the bowl group upper end being arranged on bicycle head tube, vertical and handlebar, pipe spreader is provided with fastening seat, fastening
There is one section of fluting in the middle of seat, so that pipe spreader is connected with vertical tube of front fork with trip bolt, vertical front end is provided with for clamping handlebar
Hinge type Camlock clamp ring, inserts pipe spreader vertical rear end, and vertical inside is provided with an adjusting screw rod, and adjusting screw rod two ends are respectively
Threaded two withstanding tight blocks, one of hold out against to block and pipe spreader wall contacts, another piece of withstanding tight block passes through locking clamp ring
On through hole contact with handlebar, when compressing handlebar by locking clamp ring, handlebar promotes two withstanding tight blocks to the movement of vertical rear end
Compression pipe spreader, is having for the convenient opening adjusting adjusting screw rod making end, adjusting screw rod two ends are respectively provided with left-right rotary
Screw thread.
Described pipe spreader upper end exceeds vertical, has a gland to push down pipe spreader in pipe spreader upper end, has a screw in gland
It is connected with " heronsbill " nut in vertical tube of front fork, for adjusting front fork and bowl group gap.
Withstanding tight block in the vertical and pipe spreader and handlebar position that cooperates there is anti-skidding straight burr groove.
Described pipe spreader is divided into two sections being connected up and down, and the diameter of the epimere with anti-skidding straight burr groove is more straight than smooth hypomere
Footpath is little, so that vertical one end is enclosed within the epimere with anti-skidding straight burr groove, and the platform being formed by the epimere of pipe spreader, hypomere props up
Support, the epimere with anti-skidding straight burr groove is matched with another withstanding tight block with straight burr groove, simultaneously on the top with straight burr groove for the handlebar end
Tight block is matched with handlebar band straight burr groove location.
The invention has the beneficial effects as follows：Rotary bicycle can be facilitated vertical, so that handlebar is can rotate to and vehicle body parallel, and with
When brake rotation to handlebar lower section, thus greatly reducing the width of car load, being easy to deposit and packing.
Brief description
Fig. 1 is the rotating state diagram of the present invention rotatable cycle arm assembly.
Fig. 2 is the structure cross-sectional schematic of the present invention rotatable cycle arm assembly.
Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further detail：
As shown in Figure 1, 2, the rotatable cycle arm assembly of the present invention, including the bowl being arranged on bicycle head tube 1
Organize the pipe spreader 3 of 2 upper ends, vertical 4 and handlebar 5, pipe spreader 3 is provided with fastening seat 6, has one section of fluting 7, use in the middle of fastening seat 6
Trip bolt 8 makes pipe spreader 3 be connected with vertical tube of front fork 9, and vertical 4 front ends are provided with the hinge type Camlock for clamping handlebar 5
Clamp ring 10, vertical 4 rear end insertion pipe spreaders 3, is provided with an adjusting screw rod 11 standing, screw thread connects respectively at adjusting screw rod two ends inside 4
Connect two withstanding tight blocks 12, one of hold out against to block 12 and pipe spreader 3 wall contacts, another piece of withstanding tight block 12 passes through locking clamp ring
Through hole on 10 is contacted with handlebar 5, and when compressing handlebar 4 by locking clamp ring 10, handlebar 5 promotes two withstanding tight blocks 12 to vertical
4 rear ends are moved, and compress pipe spreader 3, and vertical 4 lower ends are being had for the convenient opening 13 adjusting adjusting screw rod 11, adjusting screw rod 11
Two ends are respectively provided with left-right rotary screw thread 14.Rotating adjusting screw rod 11 can make two withstanding tight blocks 12 move forward and backward simultaneously, thus scalable
Two withstanding tight blocks 12 and the thrust of handlebar 5 and pipe spreader 3.
Described pipe spreader 3 upper end exceeds vertical 4, has a gland 15 to push down pipe spreader 3 in pipe spreader 3 upper end, in gland 15
A screw 16 is had to be connected with " heronsbill " nut 17 in vertical tube of front fork 9, for adjusting front fork 18 and bowl group 2 gap.
Withstanding tight block 12 in vertical and pipe spreader 3 and handlebar 5 position that cooperates there is anti-skidding straight burr groove 19.
Described pipe spreader 3 is divided into two sections being connected up and down, and the diameter of the epimere with anti-skidding straight burr groove 20 ratio is under smooth
Section diameter is little, so that vertical 4 one end is enclosed within the epimere with anti-skidding straight burr groove 20, and is formed by the epimere of pipe spreader 3, hypomere
Platform 21 supports, and the epimere with anti-skidding straight burr groove is matched with another withstanding tight block 12 with straight burr groove, simultaneously in handlebar 5 end band
The withstanding tight block 12 of straight burr groove is matched with handlebar band straight burr groove location.
During use, at opening 13, adjust adjusting screw rod 11, make two withstanding tight blocks 12 loose with pipe spreader 3 and handlebar 5 respectively
Open, so that handlebar 5 is can rotate to and vehicle body parallel, and carrousel handle simultaneously, make brake the underface of rotation to handlebar.
Embodiment described above is merely to illustrate technological thought and the feature of the present invention, its object is to make in the art
Technical staff it will be appreciated that present disclosure and according to this implement it is impossible to only to limit the patent model of the present invention with the present embodiment
