Description

A kind of linkage

Technical field

The utility model relates to a kind of device that is used for mechanical rotation, is specifically related to a kind of linkage.

Technical background

At present, the turning joint mechanism that uses always in the mechanical structure mostly is the single axle rotation hinge greatly, its whole linkage has only a center of rotation, and its problem that mainly exists is, because have only a force bearing point, cause being connected to each other two parts unbalance stress of rotation easily, influence the normal use of parts; In addition, also can be easy to generate the rotation dead angle because of the reason of angle, the rotation stuck phenomenon occur, in large-scale steel structure, this kind defective is particularly outstanding.

In sum, develop a kind of stressed evenly, assembling rationally, linkage that stability is strong, become the active demand of mechanical industry.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is intended to, and a kind of linkage is provided, and its rotation is flexible, simple in structure, join strength is high and good stability.

For achieving the above object, the utility model adopts following technological scheme:

A kind of linkage, at least comprise left hinge base, right hinge base, this linkage also includes the left crank assemblies that is articulated in respectively on described left hinge base, the right hinge base, right crank assemblies, described left crank assemblies and right crank assemblies are rotatably connected, described left hinge base is provided with the left limit device with described right crank assemblies coupling, and described right hinge base is provided with in the right limit device of described left crank assemblies coupling.

Described left limit device, right limit device are for being arranged at left limit chute, the right limit chute on described left hinge base, the right hinge base respectively.

Described left crank assemblies comprises a left crank at least, and an end of described left crank is articulated on the described left hinge base by a left rotary shaft, and its other end is movably connected on described right limit chute; Described right crank assemblies comprises a right crank at least, and an end of described right crank is articulated on the described right hinge base by a right spindle, and its other end is movably connected on described left limit chute.

The end that described left crank is connected with described right limit chute also is socketed with a left sliding axle; The end that described right crank is connected with described left limit chute also is socketed with a right sliding axle;

Described left crank and right crank pass through a rotation axis hinge joint.

Described left hinge base, right hinge base are provided with mounting hole.

The linkage that the utility model is set forth, its beneficial effect is: owing to adopt two rotating shafts, it rotates flexibly, and stability is strong; The utility model is simple in structure, can satisfy the connection needs of higher-strength.

Embodiment

Below, in conjunction with the accompanying drawings and embodiment,, be described further linkage of the present utility model:

As Fig. 1,2,3, be a kind of linkage of the present utility model, comprise left hinge base 1, right hinge base 2, its both structures are identical, and be symmetrical arranged, at the medial extremity of left hinge base seat 1, be provided with the two left cranks 3 that are fitted with setting parallel to each other in two grooves, 13, two grooves 13, two left cranks 3 are by running through its two and the left rotary shaft 5 of two grooves 13, the two is installed in the medial extremity of left hinge 1 with it, and thus, two left cranks 3 can rotate with respect to left hinge base 1.

Fig. 1,2 for another example, and in conjunction with Fig. 3, above-mentioned hinge base 2 medial extremitys comprise two grooves 23, its the two and above-mentioned two grooves 13 stagger mutually, plug-in mounting two right cranks, 4, two right cranks 4 parallel to each other change its two and the right spindle 6 of two grooves 23 by passing within it, and the two is installed in the medial extremity of right hinge 2 with it, thus, two right cranks 4 can rotate with respect to right hinge base 2; Because above-mentioned groove 13 staggers mutually with groove 23, then two left cranks 3 and two right crank 4 interlaced arrangements in left crank 3 and right crank 4 neutral positions, run through being connected with a pivot 7, two left cranks 3 and two right cranks 4 are hinged.

Referring to Fig. 3, one end of above-mentioned two left cranks 3 and left hinge base 1 articulate, be socketed with vertical and its two sliding axle 31 at the other end of two left cranks 3, on right hinge base 2, be provided with the chute 22 that clamps described sliding axle 31, and chute 21, the two left cranks 3 that are slidingly connected for two left cranks 3 are during according to the rotational of left rotary shaft 5, it is socketed with an end and the sliding axle of sliding axle 31, and the length direction according to chute 21, chute 22 slides respectively; Identical with it, two right crank 4 one ends and right hinge base 2 articulate, at its two the other end socket sliding axle 41, on left hinge base, be provided with the chute 11, the chute 12 that supply sliding axle 41 and two right cranks 4 to be slidingly installed, the sports rule of two right cranks 4, identical with above-mentioned left crank 3, do not do repeat specification here.

As shown in Figure 4, above-mentioned linkage is positioned at original state (rotation angle is 0), sliding axle 41 and sliding axle 31 all are positioned at the outer end with the chute of its coupling, as shown in Figure 5, for above-mentioned linkage turns to user mode (rotation angle is 90 degree), sliding axle 41 and sliding axle 31 all are positioned at the bottom with the chute of its coupling, it should be noted that at this, sliding axle 41 is mounted on the bottom with the groove of its coupling, sliding axle 41 can not be postponed again and the chute of its coupling slides, therefore the motion of right crank 4 is defined, and it can not be rotated with respect to right hinge base 2 according to right spindle 6 again; Same, this moment sliding axle 31 movable to the bottom of the chute of its coupling, the motion of left crank 3 is defined, thereby can not rotate with respect to left hinge base 1 according to left rotary shaft 5.

The left and right crank of above linkage, and the degree of depth of chute are to be 90 when spending at the maximum rotation angle that needs in the steel structure, design; According to general mechanical known theory, certainly at the degree of crook of above-mentioned crank, and the degree of depth of chute, design the linkage of different rotation angles.

In addition, on left hinge base, right hinge base, be respectively arranged with mounting hole, with equipped two members that are rotationally connected mutually.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technological scheme described above and design.
