Description
Technical field
The present invention relates to the locking mechanism of mechanical connection, more particularly to a kind of self-locking folding for being conveniently used for electric motor bicycle with folding
Folded device.
Background technology
Bicycle is constantly subjected to the welcome of people as a kind of important vehicles, since the advent of the world.Folding bicycle
Because volume after folding is small, deposit convenient transportation, with more superiority, so folding bicycle be increasingly becoming people ride instead of walk with
One of important instrument of body-building.General folding bicycle or electric motor bicycle with folding are all the foldings by being installed on the crossbeam of car
Device realizes the folding of front and back wheel.Folder is also referred to as hinge locking device, with the continuous development of folding bicycle, existing folding
Most of device realizes fastening self-locking using the device similar to clamping pin mechanism.As shown in figure 1, a kind of self-locking folder, it is wrapped
Include：The front connector 1 of the hinged tabular in side and rear joint 2, the middle part of the free side of rear joint are hinged one handle 3, should
The medial surface of handle is provided with a connecting rod 60, and the upper end of the connecting rod 40 is hinged by shipping and reselling on another market with handle, and the lower end of the connecting rod 60 passes through
One screw 101 50 is connected with another ship and resell on another market located at the middle part of the free side of front connector 1, and a Bolt with latching action 80 is cased with connecting rod.Should
Latch upper end is sleeve pipe, and the lower end of sleeve pipe extends flat inserted link, self-locking spring 70 is provided with sleeve pipe inner circle, the connecting rod 60
Bottom is provided with the back-up ring 100 for stopping that the Bolt with latching action 80 skids off downwards.Currently, rear joint 1,2 draws close folding, and up time rotates hand
Handle 3, Bolt with latching action 80 are slid and compress self-locking spring 70 upwards by resistance before this, and front connector is approximately perpendicular to when handle is gone to
During 1 plane, Bolt with latching action 80 slides downwards in the presence of the restoring force of self-locking spring 70, the flat of the lower end of Bolt with latching action 80
Inserted link will be inserted located at front connector 1 from lock crossbeam 90, so as to form self-locking.Set as long as being pulled axially upwards along connecting rod 60
In the pulling plug on sleeve pipe, the flat inserted link of lower end will exit front connector 1 from lock crossbeam 90 so that releasing self-locking, the inverse time turns
After fixed handle 3, it is possible to joint before and after opening.The Handleset of this structure is complicated, cumbersome for installation.Particularly when releasing self-locking
Afterwards, connecting rod 60 still connects forward and backward joint, i.e., connecting rod is also horizontal between forward and backward joint.This for needing relevant accessory,
Such as the demand in the cavity of the dynamic battery of electric car or maintenance tool and other items storage and girder, it can not just meet.
Therefore, a kind of simple in construction, installation facility how is provided, departing self-locking folder is industry to forward and backward joint again
Boundary's technical problem urgently to be resolved hurrily.
The content of the invention
In order to solve the defects of above-mentioned prior art is present, a kind of simple in construction, installation of proposition facilitates the present invention, forward and backward
The self-locking folder that joint can depart from.
A kind of self-locking folder for departing from angle adjustable proposed by the present invention, it includes：The be hinged front connector in side and
The be hinged handle of rear joint, one end and rear joint, the medial surface of the handle free end is held out against provided with one ships and resell on another market.Also include a spiral shell
Bar, its one end is shipped and resell on another market with described holding out against is threadedly coupled and can be held out against around this shaft core rotation of shipping and reselling on another market, and the other end of the screw rod is half
Bulb, the free side of the front connector is provided with a bulb groove, before rotational handle make it that the hemispherical head insertion of the screw rod is described
The bulb groove of joint is so that front connector and rear joint folding locking.
Preferably, the safety pin that can be moved back and forth axially along a screw is cased with described screw rod, when the half of the screw rod
When bulb is embedded in the bulb groove of the front connector, in the described bulb groove of described safety pin insertion.
Preferably, described safety pin includes：The outside being placed on the screw rod is provided with the sleeve pipe of pulling plug, sleeve pipe inner circle
In be provided with and be enclosed on self-locking spring on screw rod, the self-locking spring is limited to sleeve pipe inner circle bottom stage and described hold out against ships and resell on another market it
Between, the flat inserted link in the pluggable bulb groove is extended in one end of sleeve pipe, and the flat inserted link both sides are provided with self-locking fin；
The bulb groove side of the front connector is additionally provided with the boss that one side is circular arc, and rotational handle causes the self-locking of the inserted link both sides
Fin can slide with the arc surface of the boss and compress described self-locking spring, when the described ball of the hemispherical head insertion of the screw rod
During head groove, the sliding of described self-locking flaps down is stuck on the vertical plane of the boss.
Preferably, the other end of described sleeve pipe, which extends to be posted by, described holds out against the anti-rotation banking stop for shipping and reselling on another market cylindrical.
Preferably, the handle inner surface for holding out against the safety pin side shipped and resell on another market is provided with a back-moving spring against described
Screw rod.The medial surface corresponding position that one end and handle shipped and resell on another market is held out against described in screw rod stretching is provided with a confined planes.
Preferably, being provided with described handle confined planes can be against the adjusting screw of the screw rod external part.
Preferably, reduction torsion spring is cased with the rotating shaft that described handle is hinged with rear joint.
The screw rod that the present invention is set, its one end are threadedly coupled and the other end is hemispherical head with holding out against to ship and resell on another market, and rotational handle can
To cause in the bulb groove of hemispherical head insertion front connector, to reach a self-locking.It is front and rear to connect when rotational handle unlocks
Head completely disengages, and is connected between the two without connecting rod.At this moment facilitate and battery or maintenance tool and other items are put into the hollow of car
In girder.Safety pin is set on screw rod, and when the hemispherical head of screw rod is embedded in the bulb groove of front connector, safety pin is inserted
Enter in bulb groove, form secondary self-locking.Between safety pin is limited in the hemispherical head of screw rod and holds out against and ship and resell on another market, built-in spring,
So that it slides freely, will not fall off.The anti-rotation banking stop of the sleeve pipe of safety pin be posted by hold out against ship and resell on another market it is cylindrical, to prevent
Safety pin is around screw rod axis rotation.In the handle inner surface for holding out against both sides of shipping and reselling on another market, confined planes and adjusting screw and reset are set
Spring can be with the angle between adjusting screw rod and handle, and the bulb that front connector is fast and accurately embedded in so as to the hemispherical head of screw rod is recessed
In groove, self-locking is formed.Reduction torsion spring is cased with the rotating shaft that handle and rear joint are hinged, when unlocking, handle has certainly
The dynamic elastic force unclamped, quickly to open folding.The present invention can realize secondary auto-lock function, as long as Handleset is transferred to reset
Torsion spring just easily installs.The present invention is simple in construction, and easy to use, reasonable stress, self-locking are relatively reliable, and use the longevity
Life extends.
