Description

The steel wire hook

Technical field

The present invention relates to a kind ofly be fixed on a steel wire hook on the mounting plane to packing ring or Sealing and analog.Usually be used in baking box, refrigerator, microwave oven and some heating plants the door on Sealing on.

Background technique

Periphery at the door of baking box, refrigerator, microwave oven and some heating plants has the packing ring of tubulose, and these packing rings mainly seal but other purposes are also arranged.These packing rings are to be made up of the outer protective sleeve that the skeleton that favorable elasticity is arranged of metal wire rod braiding and insulating material weave.This structure has been proved and can in the self-cleaning baking box of continuous high temperature, have used, and still good sealing property can be provided although also be proved simultaneously oven door through for many years the packing ring of switch repeatedly.

The method that the packing ring that this pipe is adorned is installed on the heating plant door is accomplished by the independently hook that connects packing ring and door-plate usually.Hook has mutually perpendicular head and bottom to constitute.The bottom of hook weaves or is embedded in the packing ring, and head embeds the mounting hole on the oven door, thereby packing ring is installed on the oven door.

U. S. Patent NO5; 107; 623 provide a solution, but after being installed to hook in the packing ring, be difficult under the situation of not destroying packing ring hook are taken off, and take off by force then and can cause the sealing of damaging and having a strong impact on packing ring to the sheath of packing ring outer layer insulation material braiding.As take this solution then this hook can only pack into when the weaving fiberglass with machinery, in the braiding process, just mean scrapping of whole packing ring if any a hook generation problem.In addition, owing to be with flexible skeleton and other parts not to have any intersection or tie point, so skeleton very easily skids off or produces bigger displacement from outer sheath tube, must be fixed with another parts at whole packing ring two ends when adopting this solution for this reason.

U. S. Patent NO7; 124; 540 provide another kind of solution, and afterbody adhesion packing ring outer wall is very easily caused when the oval and hook of afterbody that has a weak point is on being installed to packing ring in this bottom, causes the depression of whole packing ring at this hook place; Thereby influence sealing, and this influence is fatal for the sealing of heated chamber thermal capacitance chamber; Also because the existence of this afterbody, the hand that operator can take place when being installed to packing ring on the oven door by the afterbody of perk stab maybe.And the hook that provides of this scheme is directly embedded in the packing ring when being difficult in the packing ring braiding.

It is circular also having the bottom of the solution that a kind of U. S. Patent NO2009/0144949 provides; Have one or several thrust on the chassis; Thrust plane, place and hook head portions plane parallel, the hook that this scheme provides occiput in being installed to packing ring can rotate along the axis of top and neck, and such rotation can bring operator very big puzzlement; And; The hook that this scheme provides because chassis wire end is squeezed and perk, still can't avoid chassis wire end to stab the generation of the probability of operator's hand in the as installed process on being installed to mounting plane the time.In addition; Because the bottom of the hook that this scheme provides is circular; After packing ring is installed on the mounting plane, because the diameter of hook bottom makes the cross section of packing ring become an irregular shape to the horizontal extruding of packing ring, and such distortion will directly cause the inefficacy of heated chamber thermal capacitance chamber sealing.

The solution that U.S. Patent number NO2008/0256793 A1 provides is that spirality is processed in the hook bottom; 2 ~ 3 circles are twined with wire in the hook bottom; Exist to be similar to the screw-shaped form, and have one along the circumferential direction or to the center of circle, chassis to extend the also afterbody of perk.The hook of this form since the wire of component chassis close up each other and do not have the gap, thereby the packing ring outer fabric is very easily damaged when causing being installed to packing ring, and the consequence that the breakage of packing ring outer fabric causes is exactly the inefficacy of heating container thermal capacitance chamber sealing.And the afterbody of perk can be stabbed operator's hand.

Summary of the invention

The purpose of this invention is to provide a kind of steel wire hook, this hook can prevent effectively that hook tail end in the installation process from stabbing the generation of operator's phenomenon, also can prevent to link up with that tail end and packing ring adhesion cause gasket deforms and the seal failure that causes simultaneously.

The technological scheme that realizes above-mentioned purpose is: a kind of steel wire hook; This hook comprises the head and the bottom of being processed by metal wire rod, and head and bottom link together, and head and plane, place, bottom are orthogonal; Head has the left side shoulder of the top of a band circular arc and the symmetry that metal wire rod extends to form, right shoulder downwards; The head lower end have one with bottom short pin in an angle, and short pin is to the top-direction perk, the bottom is similar to ellipse; And by metal wire rod coiled in the horizontal direction; The bottom has a terminal crooked long pin, and long pin end to hook base plane below and hook head portions place plane bending, has bigger gap between long pin end and the bottom section body simultaneously.

After adopting technique scheme, smooth bottom and can firmly and effectively packing ring be fixed on the attachment face to the short pin of top perk.Oval-shaped base and packing ring skeleton were at grade after hook was installed; Reclinate long pin end only is embedded into the half the of packing ring skeleton thickness; Effectively prevented hook tail end in the installation process to stab the generation of operator's phenomenon, also solved that hook afterbody and packing ring adhesion cause gasket deforms simultaneously and the seal failure that causes.Steel wire hook of the present invention has solved the problem of hook head portions rotation effectively, has also solved packing ring internal layer and outer field axial displacement phenomenon simultaneously.Also solved the problem that mechanical installation and manual installation can't realize on same model hook.
