Specific embodiment

For that can be illustrated more clearly that the utility model, now lift preferred embodiment and be described in detail with the accompanying drawings as follows.It please join Shown in Fig. 1 to Fig. 3, be one first embodiment of the utility model lifting bolt 100, include a lantern ring 10, a screw rod 20, One fastener 30 and a spring 40.

The lantern ring 10 has the base portion 12 being connected and a ring portion 14.The base portion 12 has a perforation 122, for the spiral shell Bar 20 is worn；The ring portion 12 is located at the top of the base portion 12, and the space that the ring portion 12 is surrounded for such as suspension hook, lifting rope, hang Refining etc. passes through and is connected to ring portion 12.

The screw rod 20 is connect with the lantern ring 10, which has the head 22 being connected and a shaft 24, the bar First 22 top has one first holding section 222, and the shaft 24 is being fixed in an object (not shown).In this present embodiment, First holding section 222 be within for hex-shaped recess, the shaft 24 has screw thread, with for being bolted in the object On or connect the object indirectly.

Please coordinate together shown in Fig. 3 and Fig. 4, which has one second holding section 32 being connected and two arms 34.Second holding section 32 matches with first holding section 222, to be incorporated in first holding section in reversible manner On 222, which is separated with certain distance, and two arms 34 to the both sides that protrude out to the ring portion 14 respectively and in An abutment face 342 is respectively arranged on two arms 34 (with reference to Fig. 6).In this present embodiment, described second holding section 32 with The structure that two arms 34 are one of the forming, second holding section 32 are the hexagon posts to match with the interior hex-shaped recess； The end of two arms 34 bends inwards and adjacent to each other, and on two arms 34 between bending place and end respectively A lug boss 341 is formed with, which protrudes towards the direction close to second holding section 32, and two protrusions Portion 341 is respectively provided with the abutment face 342, and two 342 phases of abutment face are back to setting.

It please coordinate shown in Fig. 3 to Fig. 6, which is by taking compressed spring as an example, and the both ends of the spring 40 are respectively for socket The lug boss for being butted on two arms 34 is born against or hooks in the inner edge 42 on two arms 34, and at 40 both ends of spring On 341 abutment face 342.And when spring 40 is socketed on two arms 34, two arms 34 of the spring 40 and this are defined The annular space surrounding that will be centered around ring portion 14.

Wherein, by the design of aforementioned fastener 30, please coordinate together shown in Fig. 1, when 32 knot of the second holding section of fastener 30 It closes when on the first holding section 222 of screw rod 20, fastener 30 will be with screw rod 20 with two arms 34 that are dynamic, and working as the fastener 30 Respectively positioned at the both sides of the ring portion 14 of the lantern ring 10, if at this point, the ring portion 14 affected and toward revolving clockwise or counterclockwise When turning, which will be resisted against the one of which of two arms 34 of the fastener 30, since fastener 30 and screw rod 20 are same Dynamic relationship, and screw rod 20 is fixed, therefore, ring portion 14 can not further rotate the limitation of fastener 30, so as to reachable The effect of can not further being rotated to limitation lantern ring 10 relative to screw rod 20, is referred to as to reach limitation 10 rotation angle of lantern ring Effect.

In addition, the rotation of lantern ring 10 is not limited when user's lantern ring 10 to be caused can be rotated relative to screw rod 20 or When angle or amplitude, as long as the second holding section 32 of fastener 30 to be detached to the first holding section 222 of screw rod 20, such as Fig. 2 It is shown, fastener 30 can be hung in the ring portion 14 of lantern ring 10.It is noted that by the collocation of spring 40 and fastener 30, it can So that fastener 30 is hung in ring portion 14 and not easily to fall off or loss.In addition to this, by the lug boss 341 on fastener 30 against The design in face 342 may be such that spring 40 can firmly hook be on lug boss 341, and furthermore, the inner edge of spring 40 can Be held firmly against or hook and be butted on abutment face 342, so as to, spring 40 is just not easy by external force and the both arms 34 of self-clinching fastener 30 are detached from. For example, please coordinate shown in Fig. 6, even if when pullling of 40 under tension F of spring, the inner edge 42 of spring 40 will against or hook It is butted on abutment face 342, and can reach so that spring 40 is not easy the locating effect deviate from from arm 34.

It please coordinate shown in Fig. 7,50 top view of fastener of the lifting bolt for one second embodiment of the utility model, the fastener 50 is roughly the same with the fastener 30 of previous embodiment, and specifically, each lug boss 54 of the both arms 52 of the fastener 50 is all towards remote Direction projection from the second holding section of fastener 50 and go out, and respectively the lug boss 54 equally has an at least abutment face.

It is noted that aforementioned lug boss is not limited with protrusion in the same direction, it is described two in an embodiment Lug boss also can protrude to be formed toward different directions respectively, for example, the past direction close to the second holding section of fastener of the lug boss Prominent, another lug boss is protruded toward the direction far from second holding section.It is further mentioned that, the projection direction of aforementioned lug boss Also can be protrusion upward or downward, without being limited or with second embodiment to the lug boss 341 of inner process with first embodiment Outwardly protruding lug boss 54 be limited.

It please coordinate shown in Fig. 8,60 top view of fastener of the lifting bolt for one 3rd embodiment of the utility model, the fastener 60 is roughly the same with the fastener of previous embodiment, and specifically, the both arms 62 of the fastener 60, which are respectively formed with toward different directions, dashes forward Go out two lug bosses 64,66 to be formed, for example, wherein one lug boss 64 is to inner process, and another lug boss 66 is to evagination It rises, and an abutment face is all equipped in two lug bosses 64,66.

Other one is mentioned that, the generation type of aforementioned lug boss, also can be to be formed from the peripheral surface protrusion annular in shape of arm, and It is not limited with the lug boss formed towards single direction protrusion.

It please coordinate shown in Fig. 9, be 70 top view of fastener of the lifting bolt of one fourth embodiment of the utility model, particularly It is that both arms 72 are respectively provided with a sinuous portion 74, which extends to form, and wriggle in portion 74 in this from 72 complications of arm An at least abutment face, such as in this present embodiment is formed with, respectively this wriggles, and there are two abutment faces 741,742 for the formation of portion 74.

In addition, it is noted that the lug boss on the both arms of foregoing embodiments is not limited with symmetrical, citing For, in an embodiment, wherein the embodiment of first embodiment can be selected in the lug boss of the arm, and another arm is convex The embodiment of (such as selecting second embodiment) then can be selected other than first embodiment in the portion of rising, without having left and right pair with both arms The convex structure of title is limited.

The foregoing is merely the preferred possible embodiments of the utility model, all application the utility model specifications and right Equivalence changes carried out by claimed range ought to be included in the claims of the utility model.
