Embodiment
For can the utility model be illustrated more clearly in, below lifts preferred embodiment and coordinate accompanying drawing to elaborate.
Shown in please refer to the drawing 1 and Fig. 2, the lifting bolt of the utility model one preferred embodiment includes the collar 10, pad 20 and a screw rod 30.Wherein:
This collar 10 has a base portion 12 and and is positioned at ring portion 14 on this base portion 12.This base portion 12 have one first perforation 122, and this first perforation 122 with this ring portion 14 around regional connectivity.In addition, this ring portion and this first bore a hole 122 intersection be formed with a holding area 141.Moreover, the inwall of this first perforation 122 is formed around with a convex wall 123, and this convex wall 123 is the inclined-plane 123a that an ecto-entad tilts towards the surface of this ring portion 14 circle zone.
This pad 20 has support 22 and a pad portion 24.This support 22 has one second perforation 221, and the external diameter of this support 22 be slightly less than this convex wall 123 around the bore in region.24, this pad portion is arranged around this support 22, and this pad portion 24 external diameter is slightly less than the aperture of this first perforation 122.In addition, as seen from Figure 3, this support 22 section thickness H1 slightly larger than this first perforation 122 hole depth H2.
This screw rod 30 has bar head 32 and the shaft 34 be connected, and the centre at this bar head 32 top has a hexagonal groove 321, and the surface bottom this bar head 32 is an inclined-plane 322, and this inclined-plane 322 is corresponding with the inclined-plane 123a of this convex wall 123.In addition, the external diameter of this bar head 32 is greater than the external diameter of this shaft 34, and is slightly less than the bore of this ring portion 14 circle zone.This shaft 34 then has screw thread.
Thus, designed by said structure, in time assembling, just can by this pad 20 by the first perforation 122 of this collar 10 of lower loading, then, by the shaft 34 of this screw rod 30 by this ring portion 14 around region in penetrate in this first perforation 122 and this second perforation 221, and protrude into outside this collar 10, make support 22 part for this pad 20 between this shaft 24 and this convex wall 123, and make 32, this bar head be arranged in this holding area 141.Now, this convex wall 123 will between this bar head 32 and this pad portion 24.In addition, by the design slightly larger than the external diameter of this bar head 32 of the bore of this ring portion 14 circle zone, when this screw rod 30 will be made to insert in this collar 10, too much interference can not be subject to, and the inclined-plane 123a that on this convex wall 123, ecto-entad tilts also has guide effect, and this shaft 34 can more easily be penetrated in this first perforation 122 and this second perforation 221.
Thus, just the screw 110 of the shaft 34 stretched out outside this collar 10 with a mould 100 can be combined, and screw this screw rod 30 by being inserted in this hexagonal groove 321 by hexagon wrench (scheme depending on).After this screw rod 30 screws, the bar head 32 of this screw rod 30 will be pressed against the top of this support 22 in this holding area 141, and will be connected to the surface of this mould 100 bottom this pad 20, and then reaches the object connecting this mould 100.Then, ring portion 14 and a board (scheme depending on) just by this collar 10 are connected, and then reach the object be positioned by this mould 100 on this board.In addition, by the section thickness height H 1 of this support 22 a little more than the hole depth H2 of this first perforation 122 and this convex wall 123 and this bar head 32 have opposed facets 123a, 322 design, just can make this bar head 32 and leave a little gap between this both pad portion 24 and this convex wall 123, this collar 10 is freely rotated with this screw rod 30 relative to this pad 20 by this gap, and make user after this mould 100 is connected with board, still can adjust the angle of mould 100 easily, and then promote the efficiency of assembling and adjustment.
In addition, referring to Fig. 4, is the utility model second preferred embodiment, is that the surface on the convex wall 46 of its collar 40 is plane 461 with aforementioned difference, and the bottom surface of its screw rod 60 bar head 62 is then same corresponding plane 622.And by the above-mentioned design being all plane, power when this bolt 60 can be made to lock can be distributed in the support 54 of its pad 50 comparatively fifty-fifty, so promote this lifting bolt in conjunction with time reliability.
Certainly, on reality is implemented, be not limited to be combined with this mould 100, also can be incorporated into other as sliding weight of steelyard or other have on the article of screw, and the foregoing is only the better possible embodiments of the utility model, such as the equivalence that application the utility model specification and claim are done changes, and ought to be included in the scope of the claims of the present utility model.
