Trouble, or even can not process and rivet.
The content of the invention
Technical problems to be solved in this application are the above-mentioned deficiencies overcome in the presence of the prior art, and provide a kind of knot
Structure is succinct, and reliability is high, the wide-angle turning structure of low manufacture cost.
Technical solution includes used by the application solves above-mentioned technical problem：A kind of wide-angle turning structure, is in integrally
Tubulose, it is characterized in that the wide-angle turning structure is by groove spring and cambered surface spring mutual sheathing（It is screwed on）Form, groove bullet
Spring is cross-linked with groove type by local arc and formed, and groove type is concave shape, and it is every that groove spring often encloses width+cambered surface spring
Width is enclosed to form in anteroposterior direction with cambered surface spring no more than the pitch of any one in groove spring, cambered surface spring, groove type
Recess hole, recess hole are arranged on the turning orientation of wide-angle turning structure cross section.
Herein described recess hole has two rows（Two to bending）Or four row（Four-way is bent）, recess hole along wide-angle turn tie
The circumferential uniformly configuration of structure.
The application is additionally provided with drawstring, and drawstring passes through one end of recess hole, then fixed pulling rope, pulls other the one of drawstring
Hold to drive turning mechanism to bend.
The local arc of herein described groove spring is corresponding with the periphery of cambered surface spring（Anteroposterior direction overlaps）.
Herein described groove spring, the pitch of cambered surface spring are all higher than that groove spring often encloses width and cambered surface spring often encloses
The sum of width 5 ~ 20%.
One end of herein described drawstring is fixed on one end of wide-angle turning structure, and the drawstring other end is pierced by wide-angle and turns
The other end of kinking structure.
Herein described groove type is connected and composed by three sections of arcs.
The application wide-angle turning structure using the above scheme after, improve efficiency, facilitate assembling and manufacture,
Cost has been saved, channel is provided for becoming more meticulous for product.

Embodiment
Referring to Fig. 1-Fig. 8, the embodiment of the present application wide-angle turning structure is made of two kinds of springs, the first spring is groove
Spring 1, including shown in groove spring 1 and Fig. 2 with corresponding two groove types 8 shown in Fig. 1 it is recessed with corresponding four two-by-two
The groove spring 1 of flute profile 8, the helically shape of groove spring 1, each circle is spiral-shaped is respectively provided with it is identical and corresponding（Along groove bullet
1 anteroposterior direction of spring axially corresponds in other words）；When groove type 8 has multiple in a circle, multiple groove types 8 are uniformly configured in often
The one spiral-shaped circumferential direction of circle, such as each circle shown in Fig. 1 is spiral-shaped is respectively provided with that two are identical and correspondence is circumferentially equal
The groove type 8 of even configuration, each circle shown in Fig. 2 is spiral-shaped to be respectively provided with four identical and circumferential uniformly configurations of correspondence
Groove type 8.Second of spring is cambered surface spring（Periphery is the coil spring of arc）2, groove spring 1 and cambered surface spring
2 suit connections form the wide-angle turning mechanism of a tubulose, between groove spring 1 and cambered surface spring 2 between composition anteroposterior direction
The recess hole 3 of disconnected property（Referring to Fig. 5 and Fig. 7）, can be used to wear drawstring 7.The main function of recess hole 3 is to constrain drawstring 7, is ensured
During the activity of drawstring 7 wide-angle turning mechanism can be driven movable together.
The embodiment of the present application groove spring 1 is cross-linked with groove type 8 by local arc 4 and formed, and groove type 8 is concave shaped
Shape（I.e. to the central fovea of local arc 4）, groove spring 1 often encloses width（The spiral-shaped width of each circle, similarly hereinafter.Here it is
The distance of local arc 4 or groove type 8 along the longitudinal direction）+ cambered surface spring 2 often encloses width（Loop 5 along the longitudinal direction away from
From）No more than the pitch of any one in groove spring 1, cambered surface spring 2（Two adjacent rings it is spiral-shaped along the longitudinal direction away from
From）, special case is groove spring 1, the pitch of cambered surface spring 2 is essentially identical and often encloses width+cambered surface spring slightly larger than groove spring 1
2 often enclose width, for example big by 5 ~ 20%.Drawstring 7 can use stainless steel or other materials for having some strength to be made, groove bullet
Spring 1 forms a tube-like structure after being rotatably connected with cambered surface spring 2, is adhesively fixed at both ends, after drawstring 7 passes through recess hole 3, Gu
Determine one end of drawstring 7（Can be in the end of wide-angle turning structure, can also be outside its one end）, pull drawstring 7 to be pierced by greatly
The other end of angle turning structure drives the activity of wide-angle turning mechanism, completes wide-angle and turns, referring to Fig. 8.
Structure shown in Fig. 4 is suitable for the application scenario that two corresponding directions are turned, and the structure shown in Fig. 6 is suitable for four
The application scenario that direction is turned.Need to be bent upwards, just wear a drawstring in a recess hole 3 above Fig. 4 or Fig. 6, it is necessary to
It is bent downwardly, just wears a drawstring, when needing left and right directions to turn, principle phase in a recess hole 3 below Fig. 4 or Fig. 6
Together, that is, bending direction is being needed（The turning orientation of wide-angle turning mechanism cross section）Recess hole 3 in wear a drawstring.
Simple deformation or the combination of every present techniques feature and technical solution, it is considered that fall into the protection of the application
Scope.
