Bicycle has been subjected to people's welcome as a kind of important vehicle always 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 all are to realize folding by folder, folder also claims the hinge latching device, follow the continuous 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 fashionable at bicycle lock, motive force or propelling thrust between the vehicle body of front and back all concentrate on the bayonet lock, bayonet lock is easy deformation under the concentrated load effect of such power, be not easy after folding to launch, after long-time the use, fasten the position and become lax easily, whole folder is not easy to launch and is folding.
How a kind of firm self-locking folder is provided is the technical matters that industry needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is the defective that exists at above-mentioned prior art, proposes a kind of self-locking folder.
The technical solution adopted in the utility model is, design a kind of self-locking folder, comprise: the front connector that an end is hinged and back joint, the hinged one handle of free end of described back 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, described pipe link lower end screw thread docks described tight lifting pin, also be provided with a hook with safety tong mechanism on the 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 cooperate the closed and locked of realization front connector and back joint.
In one embodiment, described hook with safety tong mechanism comprises: be placed in a sleeve pipe on the described pipe link, be provided with this sleeve pipe bottom square latch, be located at these square latch both sides with self-locking card described self-locking boss kayser, 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 the described pipe link, the interior round bottom portion of sleeve pipe and the annular shaft shoulder on the pipe link limit the two ends of this spring.
The corresponding setting with the self-locking card of self-locking boss in the described front connector, the outside of self-locking boss is cambered surface; Have the groove that cooperates 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 hook with safety tong mechanism that the utility model adopts is enclosed within on the 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 prolong service life.Open in the 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, accurately fasten in order to guarantee self-locking card and self-locking boss.The utility model can be realized auto-lock function, and is simple in structure, easy to use.

Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is section-drawing of the present utility model;
Fig. 3 is the structural representation of hook with safety tong of the present utility model mechanism;
Fig. 4 is the structural representation of the utility model front connector.
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 utility model proposes comprises: front connector 1, back joint 2 and handle 3, and wherein front connector 1 is hinged with back joint 2, and handle 3 is hinged with the free end of back 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 the tight lifting pin 5, locating dowel pin 4 passes the keyhole of pipe link 6 upper ends, pipe link 6 lower end screw thread butt joint tight lifting pins 5, and being 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 mechanism and realize that front connector 1 is closed and locked with back joint 2.
Shown in Fig. 3,4, hook with safety tong mechanism comprises that one is enclosed within the sleeve pipe 8 on the 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 the pipe link 6, the interior round bottom portion of sleeve pipe 8 and the annular shaft shoulder 13 on the 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 cooperates with square latch 801 in the front connector 1 of corresponding square latch 801.Extending to handle 3 outsides on the sleeve pipe 8 has a push button 12, and the side of handle 3 is provided with fluting and cooperates 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 back joint 2 are folding earlier, again handle 3 up times are upwards promoted, pipe link 6 drives the self-locking card 11 of hook with safety tong mechanism along the 7 upwards slips of cambered surfaces 701 of self-locking catch simultaneously, also upwards promotion passively of whole hook with safety tong mechanism in the sliding process, sleeve pipe 8 cooperates the annular shaft shoulder 13 compression 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 back joint 2, behind the groove 101 that handle 3 sides and square latch 801 snap in, before having limited, back joint mutual dislocation up and down moves.The second, unfolded device operation, only need 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 on handle can outwards be swung the inverse time, thereby removes self-locking, the unfolded device, whole operation is convenient.After unclamping, spring 10 is also stretched out, and at this moment, hook with safety tong mechanism breaks away from spring to lower slider fully in order to prevent sleeve pipe 8, the downslide of the square latch 801 of banking stop 9 restrictions of setting, and keep the proper height of hook with safety tong mechanism.
Above-described embodiment only is used for the explanation specific embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
