Described link assembly also comprises respectively drive link assembly movably on first connecting rod group and second connecting rod group of an end, and the other end of drive link assembly and described leading screw are hinged.
Preferably, described drive link assembly comprises two drive link that are symmetrically arranged in described leading screw both sides, can described first connecting rod group or of described second connecting rod group connect the collar that connecting rod moves and be fixed on the end of drive link, the other end of drive link and described leading screw are hinged.
Preferably, the other end of described drive link is connected by spherical hinge with described leading screw.
Preferably, two of described first connecting rod group or described second connecting rod group connect connecting rod, with the right-angle side of the described left clamp clip that is connected rod hinge connection or described right clamp clip and the line parallelograms between described two connection connecting rod other ends.
Preferably, described left clamp clip and described right clamp clip are parallel with the axis of described leading screw.
Preferably, be provided with the leading screw handle in the operating side of described leading screw, described leading screw passes supporting seat and links to each other with described link assembly.
The utility model utilize symmetrical parallelogram with the conversion of motion of leading screw for the unlatching of clamp clip with closed, kept under off working state, this clamping device relaxes, and the application of leading screw guaranteed the reliability that clamps, and apparatus structure is reasonable and succinct, easy to operate, practical.
Description of drawings
The structural representation of the tetragonal clamping device of a kind of symmetrical parallel that Fig. 1 provides for the utility model.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, the tetragonal clamping device of a kind of symmetrical parallel that the utility model provides comprises bearing 6, leading screw 5, leading screw handle 7, first connecting rod assembly 3, drive link assembly 4, second connecting rod group 8, right clamp clip 1 and left clamp clip 9.Leading screw 5 passes bearing 6, can control its precession and retreat by operation leading screw handle 7.Right clamp clip 1 and left clamp clip 9 rectangular triangles, and right clamp clip 1 and left clamp clip 9 are parallel with leading screw 5 axis.
First connecting rod assembly 3 and second connecting rod group 8 respectively are comprised of two identical connection connecting rods of length, and its structure is identical, and lays respectively at the both sides take leading screw 5 as symmetry axis.One end of two connection connecting rods in the first connecting rod assembly 3 is hinged on respectively the two ends of a right-angle side of right clamp clip 1, and an end of two connection connecting rods in the second connecting rod group 8 is hinged on respectively the two ends of a right-angle side of left clamp clip 9.The other end of the connection connecting rod in first connecting rod assembly 3 and the second connecting rod group 8 is hinged fixing.
First connecting rod group 8 or second connecting rod group 3 two connect connecting rods, with the right-angle side of the left clamp clip 9 that is connected rod hinge connection or right clamp clip 1 and two connection connecting rod other ends between the line parallelograms, namely the line between the line between end points a, end points b, end points c and the end points d and end points e, end points f, end points g and the end points h is distinguished parallelogram.
When the clamping device grip objects of using the utility model to provide, turn leading screw handle 7, leading screw 5 is by bearing 6, two drive link that are connected to leading screw 5 ends by spherical hinge are mutually close, the collar 2 that is cemented in the drive link other end is mobile at the connection connecting rod, first connecting rod group 8, second connecting rod group 3 change the diagonal angle with the parallelogram of right clamp clip 1 and left clamp clip 9 and bearing 6 formation under the drive of drive link, remain the shape of parallelogram.According to the difference of folded article, the angle of drive link opening and closing is different.Because the use of leading screw 5 can guarantee after grip objects, clamping force is stable, only when turn leading screw handle 7, just can unclamp object, clamps next time.
