Further, an end of described screw rod coupling nut radially is provided with boss, and the diameter of described boss is less than the external diameter of nut, and described boss thickness is less than 1.5mm.Bolt material is selected low carbon steel or low alloy steel, satisfies 8.8 grade bolt requirement of strength.
Further, described bolt material satisfies 10.9 grade bolt requirement of strength.
Further, described thread rod part size satisfies each standard piece dimension of automobile.
Further, described bolt surface is done Zincing passivation and is processed.
Further, the thickness of described nut is less than or equal to 5mm.
Further, the radius of described spherical crown shape nut is less than or equal to 10mm.
Further, the outer surface of described screw rod is provided with the screw thread that mates with nut.
(3) beneficial effect
Technique scheme has following advantage: the bolt arrangement that the utility model provides, and it is the spherical crown shape that nut is set, and can effectively solve sharp-pointed, the outstanding higher problem of original bolt edge corner angle; By adopting embedded groove setting, can not expose with the tightening tool contact surface simultaneously, minimizing is got rusty, and improves the outer effect of decorating.
Description of drawings
Fig. 1 is the utility model embodiment bolt arrangement stereogram;
Fig. 2 is the utility model embodiment bolt arrangement side view.
Wherein: 1: screw rod; 2: nut; 3: boss; 11: plane domain; 12: groove.
Embodiment
The below describes embodiment of the present utility model in detail, and described embodiment's example is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment who is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " " center "; " vertically "; " laterally "; " on "; D score; " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only be for convenience of description the utility model and simplified characterization, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only are used for describing purpose, and can not be interpreted as indication or hint relative importance.
In description of the present utility model, need to prove, unless clear and definite regulation and restriction are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be to be fixedly connected with, and also can be to removably connect, or connect integratedly; Can be mechanical connection, also can be to be electrically connected; Can be directly to link to each other, also can indirectly link to each other by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
In addition, in description of the present utility model, except as otherwise noted, the implication of " a plurality of " is two or more.
Shown in Fig. 2-3, the utility model embodiment bolt arrangement comprises: screw rod 1 and connected nut 2, and nut 1 is the spherical crown shape, nut 2 edges of this spherical crown shape structure are round and smooth, and are sharp-pointed without corner angle, are difficult for causing scratch with the external world.The nut top of spherical crown shape has a plane domain 11, is provided with groove 12 in the described plane domain 11, and the shape of described groove 12 and tightening tool end shape are complementary.Groove 12 structures are arranged in the plane domain 11, and in the time of can guaranteeing that tightening tool acts on the bolt, the surface of contact of this bolt and tightening tool does not expose, and can effectively avoid bolt to get rusty, and prolongs the working life of bolt.Concrete, the shape of this groove 12 can be for " one " font, " ten " font, hexagonal is square or flower shape or other Common Shape.Shape and the tightening tool of this groove are complementary, and can guarantee that the power of twisting is balanced, is convenient to operate accordingly.
The thickness of this nut 2 is less than or equal to 5mm, and this thickness refers to the vertical height of nut, and the thickness of control nut 2 can guarantee that tightening tool has stronger Point of Strength on the one hand within 5mm, is convenient to the fixing of bolt; On the other hand, the thickness of this nut can farthest reduce the length of whole bolt, if too thick, putting forth effort lifting of tightening tool, but the entire length of this bolt is elongated, long bolt, so that the bolt after installing is exposed to be installed surface outward, easily get rusty, and easy scratch operator or other contact components, Security is caused certain threat.If too thin, so that the active force that tightening tool acts on the nut is less, be unfavorable for the fixed effect of bolt.The radius of spherical crown shape nut 2 is less than or equal to 10mm.Hexagonal flower shape sinking 2.4mm guarantees to tighten solid moment.
The outer surface of screw rod 1 is provided with the screw thread with the nut coupling.Concrete, this screw rod 1 screw thread is the M8 regular screw threads, cooperates the Q340B08 nut.
One end of screw rod 1 coupling nut 2 radially is provided with boss 3, and 3 diameters of described boss are less than the external diameter of nut 2.In assembly process, nut 2 does not contact with being mounted the part periphery like this, reduces the edge and draws the lacquer phenomenon.The thickness of this boss 3 is about 1mm, needing in the as installed can replace the extra plain washer of installing.
Bolt material is selected low carbon steel or low alloy steel, satisfies 8.8 grades or 10.9 grade bolt requirement of strength.The thread rod part size satisfies each standard piece dimension of automobile.
The bolt surface is done Zincing passivation and is processed, and perhaps this bolt surface can be done arbitrarily other processing according to the actual requirements, so that the practicability of bolt is expanded.
The utility model embodiment bolt arrangement be used for to be installed being connected between front pedal body and the vehicle body, perhaps needs other places of adopting bolt to connect.
The bolt arrangement that the utility model provides, it is the spherical crown shape that nut is set, and can effectively solve sharp-pointed, the outstanding higher problem of original bolt edge corner angle; By adopting embedded groove setting, can not expose with the tightening tool contact surface simultaneously, minimizing is got rusty, and improves the outer effect of decorating.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
