Description
Technical field
The present invention relates to the locking mechanism of mechanical connection, relate in particular to a kind of self-locking folder.
Background technology
Bicycle is as a kind of important vehicle, and is always welcomed by the people since coming out.Folding bicycle is deposited convenient transportation because volume after folding is little, has more preceence, so folding bicycle becomes people's one of important instrument with body-building of riding instead of walk gradually.General folding bicycle or battery-driven car are all to realize folding by folder, folder also claims hinge locking device, follow the development of folding bicycle, existing folder great majority adopt the device that is similar to clamping pin mechanism to realize fastening self-locking, but this device is when bicycle is sealed, motive force or propelling thrust between the vehicle body of front and back all concentrate on bayonet lock, bayonet lock is easily distortion under the concentrated load effect of such power, be not easy after folding to launch, after long-time the use, fasten the position and easily become lax, whole folder is not easy to launch and is folding.
How a kind of firmly self-locking folder is provided is the technical matters that industry needs to be resolved hurrily.
Summary of the invention
The objective of the invention is the defective for above-mentioned prior art existence, propose a kind of self-locking folder.
The technical solution used in the present invention is, design a kind of self-locking folder, comprise: the front connector that an end is hinged and rear joint, the hinged one handle of the free end of described rear joint, described handle top is provided with a locating dowel pin, a tight lifting pin is fixed in the bottom, described locating dowel pin passes the pipe link that a upper end is provided with keyhole, the described tight lifting pin of described pipe link lower end screw thread docking, also be provided with a hook with safety tong mechanism on pipe link, the free end of described front connector is provided with the self-locking boss, and this self-locking boss and hook with safety tong mechanism coordinate and realize the closed and locked of front connector and rear joint.
In one embodiment, described hook with safety tong mechanism comprises: be placed in a sleeve pipe on described pipe link, be provided with this sleeve pipe bottom square latch, be located at this square latch both sides with self-locking card described self-locking convex decometer lock, be located at a push button described sleeve pipe one side and that extend to the handle outside, be located in this sleeve pipe and be enclosed within a spring on described pipe link, the annular shaft shoulder on the inner circle bottom of sleeve pipe and pipe link is with the two ends restriction of this spring.
The setting corresponding to the self-locking card of self-locking boss in described front connector, the outside of self-locking boss is cambered surface; Have the groove that coordinates with square latch in the front connector of corresponding described square latch.
The lower end of described pipe link also is provided with the banking stop that the described square latch of restriction moves down.
Compared with prior art, the present invention adopts hook with safety tong mechanism is enclosed within on connecting rod, and a pair of self-locking card that is arranged on square latch both sides can fasten mutually with the self-locking boss.This structure stress is reasonable, self-locking is more reliable, and extend service life.Open in front connector groove make square latch embed wherein, and can not rotate, thereby guarantee that the self-locking card does not also rotate, so that self-locking card and self-locking boss accurately fasten.The lower end banking stop of being located at pipe link can also limit that square latch moves down for example, in order to guarantee that self-locking card and self-locking boss accurately fasten.The present invention can realize auto-lock function, and is simple in structure, easy to use.
Description of drawings
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is section-drawing of the present invention;
Fig. 3 is the structural representation of hook with safety tong of the present invention mechanism;
Fig. 4 is the structural representation of front connector of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1, 2, the self-locking folder that the present invention proposes comprises: front connector 1, rear joint 2 and handle 3, and wherein front connector 1 is hinged with rear joint 2, and handle 3 is hinged with the free end of rear joint 2.Handle 3 tops are provided with a locating dowel pin 4, a tight lifting pin 5 is fixed in the bottom, fix a pipe link between locating dowel pin 4 and tight lifting pin 5, locating dowel pin 4 passes the keyhole of pipe link 6 upper ends, pipe link 6 lower end screw thread docking tight lifting pins 5, and be arranged with a hook with safety tong mechanism, the self-locking catch 7 that the free end of front connector 1 is provided with, this self-locking catch 7 fasten hook with safety tong winding machine front connectors 1 and rear joint 2 closed and locked.
As shown in Fig. 3,4, hook with safety tong mechanism comprises that one is enclosed within the sleeve pipe 8 on pipe link 6, the bottom of sleeve pipe 8 is provided with square latch 801, the lower end of pipe link 6 is provided with the banking stop 9 that the square latch 801 of restriction moves down, be arranged with spring 10 on pipe link 6, the inner circle bottom of sleeve pipe 8 and the annular shaft shoulder 13 on pipe link 6 are with the two ends restriction of this spring 10; Square latch 801 both sides are provided with the self-locking card 11 with self-locking boss 7 kaysers, and cambered surface is adopted in the side 701 of self-locking boss 7.Have the groove 101 that coordinates with square latch 801 in the front connector 1 of corresponding square latch 801.Extending to handle 3 outsides on sleeve pipe 8 has a push button 12, and the side of handle 3 is provided with fluting and coordinates moving up and down of push button 12.
during concrete the use, consult Fig. 1, Fig. 2, first, folder from latching operation, front connector 1 and rear joint 2 are first folding, again handle 3 up times are upwards promoted, simultaneously pipe link 6 drives the self-locking card 11 of hook with safety tong mechanism along self-locking catch 7 cambered surface 701 upward slidings, also upwards promotion passively of whole hook with safety tong mechanism in sliding process, sleeve pipe 8 coordinates the annular shaft shoulder 13 Compress Springs, after slip puts in place, it is sealed that self-locking card 11 is moved down with self-locking boss 7 by the antagonistic force of spring 10, Latch lock is closed in front connector 1 and rear joint 2, after the groove 101 that handle 3 sides and square latch 801 snap in, before having limited, rear joint up and down mutual dislocation moves.The second, unfolded device operation, only need to upwards stir push button 12 this moment, and like this, self-locking card 11 breaks away from mutually with self-locking boss 7, and 3, handle can outwards swing the inverse time, thereby removes self-locking, unfolded device, whole simple operation.After unclamping, spring 10 is also stretched out, and at this moment, hook with safety tong mechanism down sliding breaks away from spring fully in order to prevent sleeve pipe 8, the downslide of the banking stop 9 square latches 801 of restriction of setting, and keep the proper height of hook with safety tong mechanism.
Above-described embodiment only is used for explanation the specific embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and variation, these distortion and variation all should belong to protection scope of the present invention.
