Description

Plastic-steel hook

Technical Field

The utility model relates to a plastic steel couple.

Background

In order to increase corrosion resistance and strength, most of the existing mining cable hooks adopt a plastic-steel combination mode, and the existing mining plastic-steel cable hooks also have the defects of strength and cost, for example, the mining plastic-steel cable hook with the patent number of 201120100070.6 adopts the plastic-steel combination mode to enhance the strength, but when a plurality of hooks are combined and used from top to bottom in sequence, the connecting column connected with the next hook is easy to break due to the force born by the connecting column, and because the hooks are hung in the side direction relative to the direction of the hook heads, the whole row of hooks are easy to incline laterally, the acting force borne by the connecting column is further increased, so that the strength increase of the connecting column is the primary technical problem to be solved at present.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: provides a plastic steel hook with simple structure, high strength and low cost.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a plastic steel couple, body in body and the metal outside in the plastics outside the body was moulded plastics in the metal, the body is the sheetmetal of platykurtic in the metal, including connector, couple portion, spliced pole and gib head, be equipped with the connecting hole on the connector, the spliced pole is located couple portion lower extreme, and spliced pole one end is fixed on couple portion, and the spliced pole other end is unsettled, and the spliced pole cooperatees with the connecting hole of next couple, couple portion lower extreme side is equipped with the reinforcement piece, the reinforcement piece is fixed on couple portion to the laminating is in the spliced pole outside, gib head portion and couple portion integrated into one piece, gib head portion front end stretch out unsettled forward, gib head portion rear end and couple portion are connected, and the thickness direction of body is perpendicular mutually with the direction that gib head portion stretched out forward in the metal.

The utility model provides a couple's beneficial effect is: directly set up the spliced pole on the body in the metal, and strengthen the piece laminating in the spliced pole outside at spliced pole position local increase, the generation of body platykurtic sheetmetal in both can guaranteeing the metal is swift, and practice thrift manufacturing cost, can also be the local increase intensity in spliced pole position that the atress is the biggest simultaneously, and can not generate too high manufacturing cost, the structure is also comparatively simple reasonable, and the thickness direction of body is mutually perpendicular with the direction that the gib head portion stretches out forward in the metal, can make the body in the metal with width or length direction remove the effect of bearing the weight, in order to reach better intensity support.

Further, the connector lower extreme is equipped with connecting slot, the couple portion upper end is equipped with connects protrudingly, connect protrudingly and cooperate with connecting slot, connect protruding convex direction and the orientation of hook head portion and parallel, connecting slot is in on the perpendicular of hook head portion orientation, establishes connecting slot at the connector lower extreme, through draw-in groove and bellied cooperation, can make the connector with the joint column the direction of connection the same with hook head portion orientation, has avoided the phenomenon of whole row couple side direction slope effectively.

Furthermore, two reinforcing sheets are respectively arranged on two side edges of the lower end of the hook part, and the structure can meet the requirement of higher strength.

Furthermore, the reinforcing sheet is of a C-shaped structure, and the strength of the middle lower part of the metal inner body can be better borrowed by the reinforcing sheet of the C-shaped structure, so that a better strength effect is achieved.

Furthermore, all be equipped with a plurality of through-holes on couple portion and the hook head portion, it is more firm with the interior body coupling of metal to set up a plurality of through-holes and can pass the through-hole when the outer body injection moulding of plastics, also can further reach the materials of practicing thrift body in the metal simultaneously.

The plastic steel hook provided by the invention is further described in detail with reference to the accompanying drawings and embodiments.
