Abstract
The utility model discloses a kind of connecting-rod bolts, comprise bolt head, screw rod, described bolt head and screw rod are integral type structure, one end connecting bolt head of described screw rod, the other end of described screw rod is provided with screw section, the intermediate portion of described screw rod is provided with two bumps, and described two bumps are front bump and rear bump.By being provided with the screw rod of two bumps, easily press-fit, long service life, middle concave section has the effect of storage wear debris, and head changes trapezoid shaped into by hexagonal, is conducive to fitting with connecting rod, attractive in appearance, and compact structure, there will not be interference situation to occur.
Description
Technical field
The utility model relates to a kind of bolt, specifically a kind of connecting-rod bolts of generator connecting rod crank mechanism.
Background technique
Connecting rod is that motor realizes work cycle, completes the major moving parts of transformation of energy.In power stroke, it is mechanical energy by the heat energy reciprocating motion of the pistons of fuel combustion generation, by crankshaft rotating movement transition, external outputting power; In other stroke, then rely on the rotator inertia of crank and flywheel, drive piston up-down by connecting rod, for work done creates conditions next time, connecting-rod bolts are used to connect crankshaft-and-connecting-rod, and its performance directly affects the quality of whole motor.Connecting-rod bolts are the unthreaded portions in bar portion is one section, not easily assembles, and presses fit into tie rod holes and easily weighs connecting rod wounded, and adopt external import in the past, but external import has a lot of inconvenience: one is supply not in time, two is that quality problems difficulty is coordinated, particularly torsion problem, three is expensive.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of connecting-rod bolts being provided with three sections of bar portions.
For achieving the above object, the utility model provides following technological scheme:
A kind of connecting-rod bolts, comprise bolt head, screw rod, described bolt head and screw rod are integral type structure, one end connecting bolt head of described screw rod, the other end of described screw rod is provided with screw section, the intermediate portion of described screw rod is provided with two bumps, and described two bumps are front bump and rear bump.
As further program of the utility model: the width of described front bump is two to three times of rear bump width.
As further program of the utility model: described front bump is rectangular circle.
As further program of the utility model: described bolt head is trapezoidal bolt head.
Compared with prior art, the beneficial effects of the utility model are: by being provided with the screw rod of two bumps, easily press-fit, long service life, middle concave section has the effect of storage wear debris, and head changes trapezoid shaped into by hexagonal, be conducive to fitting with connecting rod, attractive in appearance, compact structure, there will not be interference situation to occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left-hand view schematic diagram of the present utility model
Fig. 3 is that A of the present utility model is to schematic cross-section.
Fig. 4 is that B of the present utility model is to schematic cross-section.
In Fig. 1 ~ Fig. 4: screw rod 1, bolt head 2, screw section 3, front bump 4, rear bump 5, filtration plane 6.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, in the utility model embodiment, a kind of connecting-rod bolts, comprise bolt head 2, screw rod 1, described bolt head 2 and screw rod 1 are integral type structure, one end connecting bolt head 2 of described screw rod 1, the other end of described screw rod 1 is provided with screw section 3, the intermediate portion of described screw rod 1 is provided with two bumps, described two bumps are front bump 4 and rear bump 5, by being provided with the screw rod of two bumps, connecting-rod bolts coordinate with connecting rod when installing and are easier to press-fit, and middle concave section has and stores wear debris effect.
As further scheme: the width of described front bump 4 is two to three times of rear bump width 5, described front bump 4 is the position on main laminating connecting rod mounting hole, and required width could keep connecting bolt larger than rear bump width is stablized.
As further scheme: described front bump 4 is provided with filtration plane 6, chip can be discharged in filtration plane 6.
As further scheme: described bolt head 2 is trapezoidal bolt head, be conducive to fitting with connecting rod, attractive in appearance, compact structure, there will not be interference situation to occur.
Principle of the present utility model is: by being provided with the screw rod of two bumps, easily press-fit, long service life, middle concave section has the effect of storage wear debris, and head changes trapezoid shaped into by hexagonal, is conducive to fitting with connecting rod, attractive in appearance, compact structure, there will not be interference situation to occur.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
