Embodiment
A kind of for bolted lock washer 1, its basic structure scheme as shown in Figure 1, its center is provided with a circular hole 2, the diameter of circular hole 2 is a bit larger tham the major diameter of thread of its bolt of wanting stop 3, with guarantee its be screwed into after and described bolt between form interference fit; Around the circular hole 2 along described circular hole (2) radially offer 6 grooves 4, circumferentially uniform along circular hole (2), thus thereby make and form 6 Deformable tooths 5 between the groove 4.Below be referred to as circular lock washer.
Such as Fig. 2, Fig. 3, lock washer 1 shown in Figure 5, it is the improvement project on the basis of as shown in Figure 1 basic structure scheme; Improvement is: 1, described lock washer (1) for circular symmetry ground prune about formed kidney-shaped behind two-part, wherein two of above-below direction grooves 4 are shorter than other groove 4, such as Fig. 2, shown in Figure 5; 2, lock washer (1) is the shape of intermediate projections, as shown in Figure 3.Below be referred to as the kidney-shaped lock washer.
With the supporting bolt (3) of lock washer 1 as shown in Figure 4, nut 8 is as shown in Figure 6.
The first bolt fastening structure: as shown in Figure 7, comprise two connected piece, bolt 3 and nuts 8 that have attachment hole, connected piece comprises the upper connected piece 6 that is positioned at the top and the lower connected piece 7 that is positioned at the below, bolt 3 passes two connected pieces, before being screwed into nut 8, first be screwed into or be pressed into aforesaid lock washer 1 to described lower connected piece 7 surfaces at described bolt 3, lock washer 1 can be selected circular lock washer or kidney-shaped lock washer; Described Deformable tooth 5 deforms and is embedded in the screw thread of described bolt 3, and bolt 3 is just limited, has reached the effect of stop, not play up.
The second bolt fastening structure: the first bolt fastening structure is done following improvement, and lower connected piece 7 lower surfaces are provided with deep gouge 9, and described lock washer 1 sinks to wherein during connection.Deep gouge 9 has and lock washer 1 corresponding shape.Lock washer 1 can be selected circular lock washer or kidney-shaped lock washer.But, select the kidney-shaped lock washer to have better stopping effect, as shown in Figure 8, select kidney-shaped lock washer 1, corresponding deep gouge 9 also is kidney-shaped, is positioned at wherein and can not rotates for kidney-shaped lock washer 1; So, bolt 3 is play up not only, nor can rotate along turning direction, and stopping effect is better.Certainly, lock washer 1 also can be selected other shape with deep gouge 9, as long as non-circular, has equally the effect that prevents its rotation.
Perhaps, described bolt 3 passes first the described connected piece 6 of wherein going up, and is screwed into or is pressed into aforesaid lock washer 1 supreme connected piece 6 at bolt 3, after pass again lower connected piece 7 and be screwed into nut 8, as shown in Figure 9, have same stopping effect.And has a following advantage: when upper connected piece 6 and lower connected piece 7 are that two enterprises are when making respectively rear assembling, the MANUFACTURER of upper connected piece 6 offers down-stream enterprise's general assembly after upper connected piece 6 can being assembled with bolt 3, lock washer 1, is convenient to sharing out the work and helping one another of supporting enterprise.
Figure 10-13 is the concrete Application Example schematic representation of the present invention at the car boot frame component, this roof rack luggage rack assembly comprises for its two ends 11 that are fixedly connected with automobile ceiling 10, its link comprises end 11, bolt 3, lock washer 1, and such as Figure 10, lock washer 1 is selected kidney-shaped; Each end 11 all has attachment hole position, 12, two ends of attachment hole lower surface and is provided with corresponding kidney-shaped deep gouge (9), sinks to wherein for kidney-shaped lock washer 1.During connection, bolt 3 passes end 11 from top to down from attachment hole, and its threaded end exposes sufficient length for being fixedly connected with item fluffy 10, is screwed into or is pressed into aforesaid lock washer 1 at the threaded end that exposes and sink in deep gouge (9), as shown in figure 11.Thereafter, this roof rack luggage rack assembly also needs to install upper end cap 13 additional in two end 11, as shown in figure 13, such as the supplier as the roof rack luggage rack assembly, this roof rack luggage rack assembly can be offered down-stream enterprise and finish itself and automobile ceiling 10 are linked and packed.
The linkage structure of this roof rack luggage rack assembly and automobile ceiling 10 as shown in figure 12, Figure 12 is that the axial location B of this roof rack luggage rack assembly bolt 3 when being fixedly mounted on automobile ceiling 10 state is to sectional drawing, main part comprises above-mentioned luggage frame component and automobile ceiling 10, be equipped with a casting lug thereon 15 that installs and fixes usefulness below the mounting base 14 of two ends 11 of this roof rack luggage rack assembly, mounting base 14 and casting lug thereon 15 are jointly as upper connected piece 6; The connection part of ceiling 10 is as lower connected piece 7.Because two ends 11 of this roof rack luggage rack are provided with casting lug thereon 15, the connection part of ceiling 10 also is provided with corresponding recesses; Concavo-convex cooperation like this can make it interconnect more firm stable, especially this means of transportation that is under steam vibrations of automobile.In addition, immerse in order to prevent rainwater, one deck waterproof foamed cotton layer 16 is set between the connection part of casting lug thereon 15 and ceiling 10.
As can be seen from Figure 12, if there is not the bolt chocking construction, when being screwed into nut 8, because still there is a segment distance on the top of bolt 3 from the inner roof wall of end cap 13, bolt 3 is play and rotate along turning direction up, so that the connection of roof rack luggage rack assembly and automobile ceiling 10 is very inconvenient, be difficult to it is tightened; And use this roof rack luggage rack assembly, the installation process of itself and automobile ceiling 10 is just very efficient and convenient, connection part at automobile ceiling 10 is to fill up foamed cotton layer 16 in the groove, this roof rack luggage rack assembly is placed on the connection part of automobile ceiling 10, the threaded end of the bolt 3 that will expose inserts in the attachment hole of ceiling 10, make the threaded end of bolt 3 will pass ceiling 10, just can in car, be screwed into easily nut 8, because the effect of kidney-shaped lock washer 1 and corresponding deep gouge 9, bolt 3 is play up not only, nor can rotate along turning direction, can like a cork it be tightened.
