Below with reference to Fig. 1 to Fig. 3, to describe according to the utility model embodiment's fastener assembly 100, this fastener assembly 100 can being connected and fixed for two or more workpiece.As shown in Figure 1, fastener assembly 100 comprises: bolt 10 and packing ring 20.
Particularly, as depicted in figs. 1 and 2, bolt 10 comprises head 11 and is located at the screw part 12 of the bottom surface of head 11, and the outer circumferential face of screw part 12 is provided with screw thread, and the bottom surface of head 11 is configured to the first helicoid 113.That is to say, as shown in Figure 1, head 11 is positioned at the upper end of screw part 12, and screw part 12 is positioned at the lower end of bolt 10.Wherein, the shape of head 11 can be countersunk head, square toes or round end etc.Screw part 12 is with externally threaded cylindrical body, and externally threaded tooth form can be V thread screw, square threaded form or trapezoidal thread etc.Alternatively, can be provided with outside thread in a part for the outer circumferential face of screw part 12, remaining part is smooth surface; Also can on the whole outer circumferential face of screw part 12, all be provided with outside thread.Thus, fastener assembly 100 goes for being connected and fixed of workpiece of different occasions.
As shown in Figure 1, Figure 2 and Figure 3, packing ring 20 is suitable for being positioned on parts 40 to be tightened, and packing ring 20 is enclosed within screw part 12 and fit in the bottom surface of the end face of packing ring 20 and head 11, and the end face of packing ring 20 is configured to the second helicoid 21 with the first helicoid 113 adaptations.Wherein, the first helicoid 113, second Hand of spiral of helicoid 21 are identical with the Hand of spiral of screw thread.That is to say, packing ring 20 is between head 11 and parts to be tightened 40, fits in the bottom surface of the end face of packing ring 20 and head 11, the upper surface laminating of the bottom surface of packing ring 20 and parts to be tightened 40.Wherein, packing ring 20 is provided with the through hole (scheming not shown) that runs through its center portion, thereby the free end of being convenient to screw part 12 is connected with parts 40 to be tightened through after through hole.
According to the utility model embodiment's fastener assembly 100, by head 11 bottom surfaces are configured to the first helicoid 113, and packing ring 20 end faces are configured to and the second helicoid 21 of the first helicoid 113 adaptations, thereby increased the frictional force between head 11 and packing ring 20, and then effectively prevented that fastener assembly 100 is loosening.
Therefore, simple in structure according to the utility model embodiment's fastener assembly 100, simple with parts 40 assemblings to be tightened, and be difficult for loosening.
Alternatively, head 11 can comprise the section of screwing 111 and locking section 112, and locking section 112 is positioned at the lower surface of the section of screwing 111, and the first helicoid 113 is positioned at the bottom surface of locking section 112.The cylindrical of locking section 112 is greater than the cylindrical of the section of screwing 111.Can increase like this area of contact of the first helicoid 113 and the second helicoid 21, thereby strengthen the frictional force of head 11 and packing ring 20, can realize being connected and fixed of fastener assembly 100 and parts 40 to be tightened by screwing the section of screwing 111.
Further, the radial dimension of the bottom surface of head 11 is identical with the radial dimension of packing ring 20.That is to say, the cylindrical of the bottom surface of head 11 is identical with the cylindrical of packing ring 20, like this, can make the first helicoid 113 and the second helicoid 21 obtain best fiting effect, thereby further prevents that fastener assembly 100 is loosening.
Further, as shown in Figures 2 and 3, packing ring 20 is provided with positioning hole 22, and fastener assembly 100 also comprises locating piece 30, and locating piece 30 runs through positioning hole 22 so that packing ring 20 is positioned on parts 40 to be tightened.In other words, by locating piece 30, packing ring 20 is positioned on parts 40 to be tightened in advance, one end of locating piece 30 is positioned on packing ring 20, and the other end of locating piece 30 is positioned on parts 40 to be tightened.Like this, as shown in Figures 2 and 3, during rotating bolt 10, the first helicoid 113 produces a power N perpendicular to the second helicoid 21 to packing ring 20, and the second helicoid 21 of packing ring 20 produces a reaction force N' perpendicular to the first helicoid 113 to bolt 10, it is identical that the direction of the component N1' of this reaction force and bolt 10 tighten direction, and packing ring 20 can not rotate owing to there being locating piece 30, thereby plays locking effect.
In specific embodiments more of the present utility model, positioning hole 22 and locating piece 30 can be multiple and corresponding one by one respectively.Thus, can further prevent that packing ring 20 from rotating, thereby further prevent that fastener assembly 100 is loosening.
Alternatively, positioning hole 22 was upwards uniformly distributed and is spaced apart from each other in week.Thus, can make packing ring 20 stressed even in circumferential direction, effectively prevent that packing ring 20 from rotating with respect to parts 40 to be tightened.
Further, positioning hole 22 can be configured to connect the through hole of packing ring 20 on the thickness direction of packing ring 20.Thus, locating piece 30 can be positioned at packing ring 20 on parts 40 to be tightened through through hole.Advantageously, locating piece 30 is interference fitted in through hole, thus, can prevent further that packing ring 20 from rotating relative to parts 40 to be tightened.
Alternatively, locating piece 30 can be locating stud.Wherein, a part for locating stud is in packing ring 20 positioning holes 22, and another part of locating stud is in parts 40 to be tightened, and the upper-end surface of locating stud can be concordant with the end face of packing ring 20.So, between the first helicoid 113 and the second helicoid 21, there is no gap, can make the first helicoid 113 coordinate closely with the second helicoid 21.
Further, the first helicoid 113, second helix angle of helicoid 21 are identical with the helix angle of screw thread.Like this, screw bolt 10 while rotating, the screw thread on the first helicoid 113, screw rod also can rotate equal angular, thus the first helicoid 113 and the second helicoid 21, and screw thread and nut can reach best fiting effect.Thus, can further prevent that fastener assembly 100 is loosening.
Further, the pitch of the pitch of the first helicoid 113, the second helicoid 21 can be the integral multiple of thread pitch.In other words, the pitch of the pitch of the first helicoid 113, the second helicoid 21 can be identical with thread pitch, can be also twice, three times of thread pitch etc.Thus, can make bolt 10 when screwing more smoothly, and then improve fastener assembly 100 efficiency of assembling.
According to the utility model second aspect embodiment's vehicle, comprise above-mentioned fastener assembly 100.Due to above-mentioned fastener assembly 100 have simple in structure, easy to assembly and difficult loosening advantage, therefore, according to the utility model embodiment's vehicle, have easy to assembly, the advantage of stable performance.
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiments or example.
