Abstract
The utility model provides a bolt installation structure. The bolt installation structure comprises a connecting part fixed to an upper traction bar, a connecting part fixed to an upper traction bar support, a bolt, a nut and washers. The washers are Z-shaped lock washers, wherein each Z-shaped lock washer comprises two bent surfaces. One Z-shaped lock washer is arranged between a bolt head of the bolt and the connecting part of the upper traction bar support; with respect to the two bent surfaces of the Z-shaped lock washer, one is attached to the side face of the connecting part of the upper traction bar support, and the other is attached to the side face of the bolt head. The other Z-shaped lock washer is arranged between the nut and the connecting part of the upper traction bar; with respect to the two bent surfaces of the Z-shaped lock washer, one is attached to the side face of the connecting part of the upper traction bar, and the other is attached to the side face of the nut. The bolt installation structure can effectively reduce accidents caused by looseness of the bolt on the upper traction bar. When the bolt gets loose, the lock washers will deform, so that looseness of the bolt is easy to observe and find out, and measures can be taken in time to fasten the bolt. Besides, the bolt installation structure is simple in structure and convenient to use.
Description
Technical field
The utility model belongs to automotive field, relates to a kind of mounting structure, particularly a kind of bolt mounting structure.
Background technique
The installation of upper thrust rod now adopts fastening piece to install more, on upper thrust rod and upper thrust rod support, is all provided with joint, and joint is provided with through hole.Fastening piece comprises screw bolt and nut, and bolt is comprised of bolt head and screw rod two-part, coordinates with nut.When vehicle operating, unavoidably can produce mechanical vibration.Long-term mechanical vibration cause that bolt rocks, thread abrasion, make the fastening deleterious of bolt, have affected performance and the stability of vehicle.Because even rupturing, bolt looseness causes severe traffic accidents sometimes.
The anti-loose method adopting is in the market to adopt near on nut head to wear flat gasket and diagonal cut joint spring washer, utilize the resiliently deformable of spring washer, make the axial tensioning of screw pair, and it is locking to utilize keeping out of packing ring diagonal cut joint to act on, but in the frequent high vibration of automobile, anti-loosing effect is undesirable.Therefore need a kind of more effective mounting structure that prevents bolt looseness.
Model utility content
The utility model provides a kind of bolt mounting structure, and object is effectively to prevent that bolt from occurring to become flexible.
To achieve these goals, the technological scheme that the utility model is taked is:
Described bolt mounting structure, comprises bolt, the nut joint together with being bolted on, and also comprises Z-shaped lock washer, and described Z-shaped lock washer comprises two bending sides that stretch out in the opposite direction; One of them bending side is close to the side of described joint, and another bending side is close to bolt head side or the described nut side of described bolt.
Described Z-shaped lock washer has two, and one of them Z-shaped lock washer is located between described nut and described joint, and another Z-shaped lock washer is located between described bolt head and described joint.
Adopt technique scheme, can effectively reduce the accident that the bolt looseness because of upper thrust rod causes, saved maintenance cost, long service life.When bolt looseness, lock washer can be out of shape, and is easy to observe find to take to tighten up in time measure.And have simple in structure, easy to use, locking reliable advantage.

Fig. 2 is the structural representation of nut portion in structure shown in Fig. 1;
Fig. 3 is the structural representation of bolt head part in structure shown in Fig. 1;
Being labeled as in figure:
1, joint; 2, Z-shaped lock washer; 3, bolt head; 4, nut; 5, upper thrust rod; 6, upper thrust rod support; 7, bending side.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technological scheme.
As shown in Figure 1 to Figure 3, the utility model provides a kind of bolt mounting structure, comprises the joint 1, fastening piece and the packing ring that are separately fixed on upper thrust rod 5 and upper thrust rod support 6.Described fastening piece comprises screw bolt and nut 4, and packing ring is Z-shaped lock washer 2, and Z-shaped lock washer 2 comprises two bending sides 7.
Z-shaped lock washer 2 has two, and one is located between the bolt head 3 of bolt and the joint 1 of upper thrust rod support 6.7, one of two bending sides of this Z-shaped lock washer 2 are attached to the side of the joint 1 of upper thrust rod support 6, and another is attached to the side of bolt head 3.Prevent that bolt from rotating relative to upper thrust rod support 6.Another Z-shaped lock washer 2 is located between nut 4 and the joint 1 of upper thrust rod 5.7, one of two bending sides of this Z-shaped lock washer 2 are attached to the side of the joint 1 of upper thrust rod 5, and another is attached to the side of nut 4.Prevent that nut 4 from rotating relative to upper thrust rod 5.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
