Abstract
The invention relates to a quick release clamp which comprises a guide plate. The guide plate is of a square thin board structure. A central hole is formed at the center of the guide plate. A first compression chain link, a second compression chain link, a third compression chain link, a fourth compression chain link, a fifth compression chain link and a sixth compression chain link are sequentially and annularly formed along the edge of the central hole. Notches are horizontally formed at two ends of each compression chain link. A pin hole is vertically formed at each notch of the corresponding compression chain link. A guide shaft is disposed between the first compression chain link and the sixth compression chain link and between the third compression chain link and the fourth compression chain link. Connectors are disposed between the rest adjacent compression chain links. First through holes are formed at two ends of each connector which is located in the corresponding notch. The quick release clamp has the advantages that the defect that the clamp can only be applicable to small-aperture vacuum butt joint is overcome; the clamp can replace the existing threaded edge seal clamps in large-aperture vacuum part sealing; influence of vacuum part aperture on clamp sealing effect is small, and the quick release clamp can be widely applicable to sealing of large-aperture vacuum parts.

Embodiment
As Figure 1-5, a kind of Quick Release Hoop described in the embodiment of the present invention, comprise guide plate 1, described guide plate 1 is square plate structure, described guide plate 1 center is provided with center hole 101, on described guide plate 1, along center hole 101 edges successively annular, be provided with and compress chain link 1, compress chain link 23, compress chain link 34, compress chain link 4 401, compress chain link 5 301 and compress chain link 6 201, the equal level in two ends of described compression chain link is provided with notch 9, and described compression chain link is positioned at notch 9 places and is all vertically provided with pin hole 10; Between described compression chain link 1 and compression chain link 6 201 and compression chain link 34 and compression chain link 4 401, be all connected with the axis of guide 5, between all the other adjacent compression chain links, be all connected with link 8, described link 8 two ends are equipped with through hole one, and described link 8 is positioned at notch 9; The described axis of guide 5 middle parts are provided with boss 501, the described axis of guide 5 two ends are all fixedly connected with locking knob 504, on the described axis of guide 5, be positioned at boss 501 both sides and be respectively equipped with right-handed thread 502 and left-handed thread 503, in described right-handed thread 502 and left-handed thread 503, be all connected with straight pin 1, described straight pin one 7 middle part levels are provided with through hole two, are equipped with the internal thread matching with right-handed thread 502 or left-handed thread 503 in described through hole two; Described straight pin 1 is rotatably connected in the pin hole 10 of the compression chain link being connected with the described axis of guide 5, and the described axis of guide 5 is positioned at notch 9.
The two ends of described compression chain link 23 and compression chain link 5 301 are all rotatably connected with link 8 by straight pin, and described compression chain link 1, compression chain link 6 201, compression chain link 34 and compression chain link 4 401 are all rotatably connected with link 8 by coupling shaft 6.Described guide plate 1 is positioned at coupling shaft 6 belows and is equipped with long guiding hole 102, and the length direction of described long guiding hole 102 parallels with the shaft axis of the axis of guide 5.Described coupling shaft 6 middle parts are provided with limiting stopper, and described coupling shaft 6 bottoms are provided with nut, described coupling shaft 6 through long guiding hole 102 and described guide plate 1 between limiting stopper and nut.The inner side surface of described compression chain link is arc surface.The Si Ge corner of described guide plate 1 is equipped with fillet 103.
Because the screw thread on the axis of guide 5 is contrary, so when the axis of guide 5 rotates to a direction, the moving direction of two straight pins 1 that are threaded is with it inevitable contrary, or close, or away from; Accordingly, be connected with straight pin 1 two distances that compress chain links also can one change, thereby realize the fastening of clip and unclamp.
During assembling, not it should be noted that the nut of coupling shaft 6 bottoms is twisted too tightly, should keep can unrestricted motion between coupling shaft 6 and guide plate 1.
During use, the vacuum part that needs are tightly connected is put into the center hole 101 of clip, twist the locking knob 504 at the axis of guide 5 two ends, make two straight pins 1 being connected with the axis of guide 5 mutually close, and then two of making to be connected with straight pin 1 to compress chain links mutually close, and then drive all the other to compress chain links to center, to draw close, make locked clip device, reach that dense block is critical to be asked.In fastening process, along with the locking of clip, coupling shaft 6 is also drawn close to center gradually along the length direction of long guiding hole 102, makes respectively to compress chain link stressed evenly, there will not be because of the too concentrated undesirable situation of sealing effect that causes of force bearing point.If fastening amount is less, only need to rotate the locking knob 504 of an axis of guide 5; If fastening amount is larger, need to twist two axis of guides 5 simultaneously, prevent that fastening amount is excessive, when only 102 adjustings are not come by two long guiding holes, there is compressing the phenomenon of chain link unbalance stress.
During dismounting, unclamp the locking knob 504 at the axis of guide 5 two ends, take out vacuum part.
The Si Ge corner of guide plate 1 is equipped with fillet 103, both can prevent from scratching operator, can conveniently turn locking knob 504 again, prevents that the turning of guide plate 1 from encountering spanner.
Because Quick Release Hoop of the present invention comprises a plurality of compression chain links, add the design of long guiding hole 102 and the axis of guide 5, make whole clip stressed even when sealing, the requirement to tightness while connecting to meet heavy caliber vacuum.If vacuum part bore is too large, six compression chain links also cannot guarantee its sealing effect, can consider to increase the sealing effect that compression chain link further improves clip.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection scope of the present invention.
