Description
Technical field
The utility model relates to hardware fastening technical field, relates to the set screw nut on big bus link, particularly a kind of corner copper nut of anti-skidding gum-punching-preventing.
Background technique
The upper copper nut used of present big bus connecting rod (rocking arm) is circular copper nut, is roughly made up of (see Fig. 1) four parts: center tapped through hole 11, two ends round nut outer side surface 12, two ends round nut diametral plane 13 and middle circle connected in star 14 according to its structural feature.Need during production center tapped through hole 11 to be arranged on the fixing pin in rod mould, two ends round nut outer side surface 12 is formed with mould upper and lower surfaces respectively and coordinates; Like this, by the filling injection of plastic melt, in Injection Molding Products (big bus connecting rod 16), form an effective circular copper nut 15(see Fig. 3).Simultaneously, because two ends round nut diametral plane 13 have employed embossed technology technology, the outside of two ends round nut diametral plane 13 is made to form the tiny groove of a rule, two ends round nut diametral plane 13 after shaping contacts with plastic melt and can form certain frictional force and enclasping force, makes can not to be pulled out easily the circular copper nut 15 of pulling capacity and the less demanding product of torque force.But, existing circular copper nut also comes with some shortcomings: when ⑴Dang center tapped through hole 11 is arranged on the fixing pin in rod mould, because the lateral area of two ends round nut outer side surface 12 is too small, be easy to because the gap of mould cooperation is under the impact of injection pressure, in center tapped through hole 11, enter glue, affect the degree of adaptability of screw and nut.(2) minimum with the surface of contact of plastic melt after the tiny ditch Slot shaping that on two ends round nut diametral plane 13, embossed technology is formed, larger frictional force and enclasping force cannot be produced, can not meet the requirement compared with high pulling torque.(3) the cell body of middle circle connected in star 14 is more shallow, cannot meet the usage requirement of higher pulling capacity.(4) client uses rear reaction: circular copper nut and plastic casing enclasping force not, easily produce and loosen, affect quality of product.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of corner copper nut of anti-skidding gum-punching-preventing, and by structure is improved, it can make plastic melt can not enter in the tapped through hole of center when producing; Larger pulling capacity and torque force can be born after making copper nut and plastic melt forming.
For realizing above-mentioned object, the utility model have employed following technological scheme.
A kind of corner copper nut of anti-skidding gum-punching-preventing, containing center tapped through hole, two end nut outer side surfaces, two end nut diametral planes, middle circle connected in star, it is characterized in that, described two end nut outer side surfaces and two end nut diametral planes are tetragonal structure, form two ends square nut outer side surface and two ends square nut diametral plane, described two ends square nut outer side surface forms corner copper nut with described center tapped through hole with two ends square nut diametral plane together with middle circle connected in star.
Further, the width of described two ends square nut outer side surface is >=7mm.
The good effect of the corner copper nut of a kind of anti-skidding gum-punching-preventing of the utility model is:
(1) when Length x Width is equal, the area of corner copper nut both ends of the surface is larger than the area at circular copper nut two ends, can ensure that corner copper nut has enough areas and melt plastic contacts, add the frictional force between nut and plastics and enclasping force.
(2) effectively can ensure that plastic melt can not enter in the center tapped through hole of corner copper nut.
(3) processing technology is simple, is more applicable to usage requirement torque force and pulling capacity being required to high product (as big bus link).

Embodiment
Explain the embodiment of the corner copper nut of a kind of anti-skidding gum-punching-preventing of the utility model below in conjunction with accompanying drawing further, but it is noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 4.A kind of corner copper nut of anti-skidding gum-punching-preventing, two end nut outer side surfaces and two end nut diametral planes are made tetragonal structure, become two ends square nut outer side surface 22 and two ends square nut diametral plane 23, the width of described two ends square nut outer side surface 22 can be set to 7mm, center tapped through hole 21 is set in the centre of described two ends square nut outer side surface 22; Between two ends square nut diametral plane 23, middle circle connected in star 24 is set; Center tapped through hole 21 is made to form corner copper nut 25 with two ends square nut outer side surface 22 with middle circle connected in star 24 together with two ends square nut diametral plane 23.
Corner of the present utility model copper nut can adopt used technological scheme and material with on material or manufacture method.
Described corner copper nut 25 can be embedded in (see Fig. 6) on the rocking arm of big bus link.
The corner copper nut of a kind of anti-skidding gum-punching-preventing of the utility model advantage structurally compared with existing circular copper nut 15 is (see Fig. 3 and Fig. 6):
(1) diameter of two ends round nut outer side surface 12 is 7mm, and the width of two ends square nut outer side surface 22 is also 7mm, and this makes the length and width direction of two kinds of nuts equal but area does not wait (see Fig. 2, Fig. 5).The lateral area of two ends round nut outer side surface 12 is: 3.14 × 3.5 × 3.5=38.4mm
2; The lateral area of two ends square nut outer side surface 22 is: 7 × 7=49mm
2.Therefore, lateral area 49 mm of corner copper nut 25
2the lateral area 38.4mm of the circular copper nut 15 of >
2.Like this, the expansion of two ends square nut outer side surface 22 adds effective pressing of itself and upper and lower mould area, makes plastic melt be difficult to enter the center tapped through hole 21 of corner copper nut 25 when producing.
(2) after two ends square nut outer side surface 22 expands, the plastics of filling in described corner copper nut 25 middle circle connected in star 24 are than the filling of circular copper nut 15 middle circle connected in star 14 many (see Fig. 1, Fig. 4), like this, the frictional force of corner copper nut 25 and plastics and enclasping force are just larger, and corner copper nut 25 would not be pulled out in the vertical direction easily.
(3) two ends square nut diametral plane 23 planar friction and hold resistance tightly and be greater than the planar friction of the groove that two ends round nut diametral plane 13 is produced by embossed technology and hold resistance tightly, such corner copper nut 25 can meet the usage requirement compared with high pulling torque power, structurally ensure that corner copper nut 25 can not be back-outed from big bus connecting rod 26 when rotated easily and comes off.
