Abstract

The invention discloses an eyebolt arranged on an object, and the eyebolt comprises a lantern ring, a gasket and a screw. The lantern ring comprises a base and a ring part on the base; the base is opened with a first punching hole, and the first punching hole is connected to the region surrounded by the ring part; the gasket is located in the first punching hole of the lantern ring and is opened with a second punching hole; moreover, the thickness of cross section of at least one part of the gasket is greater than the hole depth of the first punching hole; the screw comprises a screw head and a screw body connected together, the screw body is provided with the thread and passes through the first punching hole and the second punching hole. When the screw body is combined with the screw hole on the object, the gasket props against the surface of the object, the screw head presses the gasket and the lantern ring can rotate corresponding to the gasket and the screw.

Description

Lifting bolt

Technical field

The present invention is relevant with bolt arrangement; Refer to a kind of lifting bolt especially.

Background technique

Generally as plastic injection molding machine platform replaces mould for convenience, when arranging mould, after the lifting bolt normally utilizing a first top to have the collar is combined with mould, the collar of recycling bolt end head is incorporated into object board reaching mould location.But aforesaid orientation type is after lifting bolt screws, mould will be made to be fixed on a certain special angle, and cannot the carrying out of angle adjust, and rotate die angle if force, getting loose easily causing mould on lifting bolt.

For improving above-mentioned shortcoming, then dealer is had to research and develop lifting bolt (eyebolt) as described in U.S. Publication No. 5690457 patent, it is the design by the collar is separated with bolt, after bolt is combined with mould, the collar at top still can reach the object of adjustment die angle by screws relatively.

But though previous designs can reach the object of adjustment die angle, its bolt is torqued-up to a certain degree, and its head may be pressed against on the collar, and make the collar be forced to and not easily rotate, and then cause assembling location and the inconvenience in adjustment.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of lifting bolt, its collar, still can its bolt rotary freely relative after bolt screws.

For achieving the above object, lifting bolt provided by the invention in order to be arranged on an object, and comprises a collar, a pad and a screw rod.Wherein, this collar has a base portion and and is positioned at ring portion on this base portion; This base portion have one first perforation, and this first perforation with this ring portion around regional connectivity; This pad is arranged in the first perforation of this collar, and has one second perforation; In addition, the section thickness at least one position of this pad, is greater than the hole depth of this first perforation; This screw rod has the bar head and a shaft that are connected, and the external diameter of this bar head is greater than the external diameter of this shaft, and this shaft has screw thread, and through this first perforation and this second perforation.

Thus, when the screw of this shaft on this object in conjunction with time, this pad is connected to the surface of this object, and this bar head is pressed against on this pad, and this collar can this pad and this bolt rotary relatively.

Embodiment

For being illustrated more clearly in the present invention, lift preferred embodiment and coordinate accompanying drawing to be described in detail as follows, refer to shown in Fig. 1 and Fig. 2, the lifting bolt of a preferred embodiment of the present invention 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, the section thickness H of this support 22 ₁slightly larger than the hole depth H of this first perforation 122 ₂.

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 the effect of guiding, 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, the ring portion 14 just by this collar 10 is connected with a board (not shown), and then reaches the object be positioned by this mould 100 on this board.In addition, by the section thickness height H of this support 22 ₁a little more than the hole depth H of this first perforation 122 ₂, 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 present invention 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 present invention, such as the equivalence that application specification of the present invention and claim are done changes, and ought to be included in right of the present invention.
