For the technical problem of supportive existing in the prior art difference, the purpose of this utility model is to provide circular steel Pipe lifting hook.

The technical solution that the utility model is taken is：

Round steel pipe suspension hook, is provided with hanging ring through hole at the top of hook body, hook body is arranged to " L " shape integral type knot Structure, extends in parallel setting supporting block, supporting block is arranged to weighted spherical ball a, supporting rod and matches somebody with somebody along the horizontal inner side wall of hook body The structure that heavy ball b is connected in sequence from left to right, the inside circulation arrangement of supporting rod are provided with support component, and support component is The arrangement that is centrosymmetric of adjacent " P " font reinforcing rib sets the structure that forms, and " P " font reinforcing rib is by " O " shape steel ring and perpendicular Allotment dagger sets up and forms, and each pair " O " the shape steel ring submission misphase in support component cuts arrangement.

Further, the weighted spherical ball a is consistent with the diameter of weighted spherical ball b, and weighted spherical ball a, the diameter of weighted spherical ball b are all higher than propping up The diameter of strut.

Further, the distance between vertical support column adjacent in the support component is less than two " O " shape steel rings The sum of diameter.

Further, it is described that the vertical madial wall arrangement of hook body is provided with wear-resistant block.

Further, the wear-resistant block along it is longitudinally disposed be resistance to grinding column, on the lateral wall of resistance to grinding column equidistantly outwards Protrusion is provided with curved surface convex block.

Further, transverse axis reinforcing bar is provided with along at horizontal center line axis in the curved surface convex block.

Further, the open end of the hook body is provided with barb.

The beneficial effects of the utility model are：

Supporting block in the utility model plays good support effect, and weighted spherical ball plays support and spacing effect, Hanging piece is avoided to come off；Support component plays stability of strutting system by support column, and two " O " shape steel rings can distinguish buffer level direction With the pressure of vertical direction, support performance is improved, compressive resistance is strong；The resistance to grinding column of wear-resistant block is strong along the support force of vertical direction, The phenomenon to deform is avoided, curved surface convex block can alleviate the frictional resistance that hanging piece forms the side wall of coupler body, to a certain extent Snap-in function is formed to hanging piece, is conducive to prolong the service life, it is applied widely.

Embodiment

The utility model is further illustrated below in conjunction with the accompanying drawings.

Embodiment 1

As depicted in figs. 1 and 2, round steel pipe suspension hook, hanging ring through hole is provided with the top of hook body, and hook body is set For " L " shape integral structure, setting supporting block is extended in parallel along the horizontal inner side wall of hook body, supporting block is arranged to counterweight The structure that ball a, supporting rod and weighted spherical ball b are connected in sequence from left to right, the inside circulation arrangement of supporting rod are provided with support Component, support component set the structure that forms, " P " font reinforcing rib for the arrangement that is centrosymmetric of adjacent " P " font reinforcing rib Set up and formed by " O " shape steel ring and vertical support column, each pair " O " the shape steel ring submission misphase in support component cuts arrangement.

When specifically used, hook body is hung by hanging ring through hole, the open end of hook body is used to hang It is located on corresponding hanging piece, when hanging piece is fastened on the openend of hook body, supporting block plays good support effect, matches somebody with somebody The hook body that the special construction of heavy ball a and weighted spherical ball b makes plays stability of equilibrium, and weighted spherical ball a and counterweight to a certain extent The diameter of ball b is consistent, and weighted spherical ball a, the diameter of weighted spherical ball b are all higher than the diameter of supporting rod.Supporting block forms the knot of medial recess Structure, makes its hanging piece link up with the firm position for being fastened on supporting rod, and weighted spherical ball plays support and spacing effect, avoids hanging piece from taking off Fall；Support component in supporting rod takes full advantage of inner space, plays stability of strutting system by support column, phase in support component The distance between adjacent vertical support column is less than the sum of diameter of two " O " shape steel rings, therefore two " O " shape steel rings interlock up and down Formula is arranged, and either vertical direction, which is also horizontally oriented, can form good closely extruding contact action, inner space Utilization rate design is reasonable, and " O " shape steel ring can distinguish the pressure of buffer level direction and vertical direction, improves support performance, resistance to compression Power is strong, is conducive to prolong the service life.

Embodiment 2

On the basis of embodiment 1, different from embodiment 1, as shown in figure 3, being arranged along the vertical madial wall of hook body Cloth is provided with wear-resistant block.

Wear-resistant block along it is longitudinally disposed be resistance to grinding column, it is equidistantly outwardly on the lateral wall of resistance to grinding column that to be provided with curved surface convex Block.Resistance to grinding column is strong along the support force of vertical direction, the phenomenon for avoiding hook body from deforming when bearing larger pressure, bent For face convex block due to lateral wall structure in curved surface, frictional resistance is smaller, can be formed and alleviate the friction that hanging piece forms the side wall of coupler body Resistance, while curved surface convex block is equally arranged, the concavo-convex spatial arrangement form staggeredly of curved surface convex block, to a certain extent to hanging Part forms snap-in function, and transverse axis reinforcing bar is provided with along at horizontal center line axis in curved surface convex block, is played a supporting role, and surface is bent Face convex block deforms.

The open end of hook body is provided with barb, after hanging piece is hung, can be carried out by barb spacing, avoid hanging piece Fall off phenomenon.

Round steel pipe Suspension hook structure is novel, easy to use, has not only saved production cost, the work for reducing worker is strong Degree, and the deformation of hook body is prevented, reduce correcting process, it is applied widely.

The above is not the limitation to the utility model, it should be pointed out that：For the ordinary skill people of the art For member, on the premise of the utility model in essence scope is not departed from, some variations, modifications, additions or substitutions can also be made, These improvements and modifications also should be regarded as the scope of protection of the utility model.
