Description

U-shaped hoisting ring

Technical Field

The utility model relates to a lifting device technical field especially relates to a U-shaped rings.

Background

The U-shaped hanging ring is a hoisting tool which has wide application in transportation and mechanical industries and plays a role in connecting and transferring load between two connected pieces. The current U-shaped hanging ring is generally shown in fig. 1, one end of the U-shaped ring 01 is a threaded hole, the other end is a smooth hole, one end of a bolt 02 is screwed in the threaded hole of the U-shaped ring 01 to play a role in load transmission and positioning, and the other end of the bolt depends on surface contact between the bolt and the smooth hole of the U-shaped ring 01 to transmit load.

The U-shaped rings of above-mentioned structure have following drawback: in order to allow bolt 02 to pass through the unthreaded hole of U-shaped ring 01 smoothly without damaging the thread of bolt 02, the unthreaded hole of U-shaped ring 01 needs to be machined into a larger hole, so bolt 02 and the unthreaded hole of U-shaped ring 01 are in clearance fit, and when a load is transmitted, the threaded hole side of U-shaped ring 01 receives the load first and receives a relatively larger load, which may cause U-shaped ring 01 to deform, so that the axes of the threaded hole and the unthreaded hole do not coincide, and further cause early failure and fracture of U-shaped ring 01. The fracture failure is a dangerous working condition, and therefore, how to improve the safety of the U-shaped hanging ring becomes a technical problem to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a U-shaped rings, this U-shaped rings can effectively avoid the U-shaped ring to take place early failure and fracture, therefore has higher security.

In order to achieve the above object, the utility model provides a following technical scheme:

a U-shaped hanging ring comprises a U-shaped ring and a bolt, wherein mounting seats are arranged on two end heads of the U-shaped ring, threaded holes are formed in the two mounting seats, and the two threaded holes are coaxially arranged;

the bolt is arranged in the two threaded holes in a penetrating mode and is provided with two threaded sections, one threaded section is matched with one threaded hole, and the other threaded section is matched with the other threaded hole.

Preferably, in the U-shaped hanging ring, the mounting seat and the U-shaped ring are of an integral structure.

Preferably, in the U-shaped hanging ring, the mounting seat is connected with the U-shaped ring in a welding manner.

Preferably, in the U-shaped suspension ring, the two threaded holes have the same diameter and the same thread specification.

Preferably, in the U-shaped suspension ring, the bolt is a hexagon head bolt.

According to the technical scheme, the utility model provides an among the U-shaped rings, threaded hole has all been seted up to the mount pad on two ends of U-shaped ring, the coaxial setting of these two screw holes, and simultaneously, the bolt has two screw thread sections, when the bolt is worn to establish in two screw holes of U-shaped ring, one of them screw thread section and a screw hole cooperation, another screw thread section and another screw hole cooperation, like this, the mount pad of both sides can divide load simultaneously in step when the loading, can not arouse the axiality change of both sides screw hole, can not arouse that U-shaped ring unilateral warp too big yet, it is thus visible, the utility model provides a U-shaped rings can effectively avoid the U-shaped ring to take place early inefficacy and fracture, has higher security. In addition, compare with the unilateral screw-thread fit of traditional U-shaped rings, both sides are screw-thread fit and can play effectual locking effect.

Detailed Description

For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 2 to 4, fig. 2 is a schematic view of a U-shaped hanging ring provided by an embodiment of the present invention, fig. 3 is a left side view of fig. 2, and fig. 4 is a schematic view of the member 2 in fig. 2.

The U-shaped hanging ring provided by the embodiment of the utility model comprises a U-shaped ring 1 and a bolt 2, wherein, two ends of the U-shaped ring 1 are respectively provided with a mounting seat 11, two mounting seats 11 are respectively provided with a threaded hole (not marked in the figure), and the two threaded holes are coaxially arranged; the bolt 2 is arranged in the two threaded holes in a penetrating mode, the bolt 2 is provided with two threaded sections 21, one threaded section 21 is matched with one threaded hole, and the other threaded section 21 is matched with the other threaded hole.

Because the mount pad 11 on two ends of U-shaped ring 1 all seted up threaded hole, and the coaxial setting of these two screw holes, and bolt 2 has two screw thread section 21, one of them screw thread section 21 and a screw hole cooperation, another screw thread section 21 and another screw hole cooperation, so, the mount pad 11 of both sides can divide load equally simultaneously in step when loaded, can not arouse the axiality change of both sides screw hole, also can not arouse that U-shaped ring 1 unilateral warp too big, it is thus visible, the utility model provides a U-shaped rings can effectively avoid the U-shaped ring to take place early failure and fracture, has higher security. In addition, compare with the unilateral screw-thread fit of traditional U-shaped rings, both sides are screw-thread fit and can play effectual locking effect.

In a specific application, the mounting seat 11 and the U-shaped ring 1 may be an integral structure, for example, the mounting seat 11 may be formed by forging or extruding the end of the U-shaped ring 1. Of course, the mounting seat 11 and the U-shaped ring 1 may be welded together instead of being integrally formed.

For the sake of installation, the bolts 2 are usually designed as hexagon head bolts.

In this embodiment, the two threaded holes of the U-shaped ring 1 have the same diameter and the same thread specification. By "thread gauge is the same" it is meant that the fit and tolerance levels are the same. In other embodiments, the two threaded holes may be designed to have different diameters, and the bolt 2 may be designed to have a stepped shaft shape, in which the external thread of the shaft section having a large diameter is engaged with the threaded hole having a large diameter, and the external thread of the shaft section having a small diameter is engaged with the threaded hole having a small diameter.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
