Abstract
The utility model discloses a kind of engine connecting rod bolt, comprise hex head bolt head, screw rod, screw section and spiral shell head; One end of screw rod is provided with hex head bolt head, and the other end of screw rod is provided with screw section, and the middle part of described screw rod is also provided with projection; The described end face being provided with the screw rod of one end, screw section is also provided with receiving groove, described receiving groove comprises bottom and joint, joint is provided with tapered thread, described tapered thread coordinates with the tapered thread of spiral shell head, described spiral shell head comprises the end cap, joint and the elastic claw that set gradually, and the length of described elastic claw is greater than the degree of depth bottom receiving groove.The utility model effectively can be collected in screw rod precession process also to remove from the greasy dirt connecting-rod bolts pore area and take out of, and greasy dirt can be stoped to enter receiving groove.The utility model smart structural design, cleaning oil pollution is easy, conveniently causes the dismounting of connecting rod and connecting rod cap, installs, is convenient to carry out full maintenance to motor.
Description
Technical field
The utility model relates to a kind of engine connecting rod bolt.
Background technique
Engine connecting rod bolt is for connecting connecting rod and connecting rod cap, and its performance directly affects the quality of whole motor.No matter be engine operation, maintenance of still changing oil, among the environment being all inevitably in greasy dirt.Because the viscosity of oil product, dust easily and greasy dirt combine, and to be attached on connecting rod and connecting rod cap, to cause connecting rod and connecting rod cap to dismantle, again difficulty is installed, full maintenance cannot be carried out to motor.
Model utility content
The utility model, for solving the problems of the technologies described above, provides a kind of engine connecting rod bolt, and it has the advantages such as dust-proof, cleaning oil pollution is convenient.
To achieve these goals, the utility model adopts following technological scheme.
A kind of engine connecting rod bolt, comprises hex head bolt head, screw rod, screw section and spiral shell head; One end of screw rod is provided with hex head bolt head, and the other end of screw rod is provided with screw section, and the middle part of described screw rod is also provided with projection; The described end face being provided with the screw rod of one end, screw section is also provided with receiving groove, described receiving groove comprises bottom and joint, joint is provided with tapered thread, described tapered thread coordinates with the tapered thread of spiral shell head, described spiral shell head comprises the end cap, joint and the elastic claw that set gradually, and the length of described elastic claw is greater than the degree of depth bottom receiving groove.
As further improvement of the utility model, described elastic claw can be 2-4 sheet.
Working principle of the present utility model is, the connecting rod bolt holes arranged due to connecting rod and connecting rod cap is longer, the greasy dirt of its inside cannot be cleared up, when being connected again after connecting rod with connecting rod cap dismounting, time advance in screw section, greasy dirt on connecting rod bolt holes internal thread can be forced down, greasy dirt enters receiving groove, and the front can not advanced in screw section is assembled.After connecting-rod bolts screw, after spiral shell head is screwed in receiving groove, because the length of elastic claw is greater than the degree of depth bottom receiving groove, therefore, the base contact surface of elastic claw and receiving groove is long-pending to be strengthened, thus after spiral shell head exits, can be taken out of by the greasy dirt that elastic claw is collected when screwing in.Repeatedly screw in spiral shell head, can remove more greasy dirt, after last screw-in spiral shell head, the opening of receiving groove blocks by end cap, thus stops greasy dirt to enter receiving bore.
The beneficial effects of the utility model: the receiving groove of screw rod one end, can collect from the greasy dirt connecting-rod bolts pore area in screw rod precession process effectively, and meanwhile, the oil removal that receiving groove is collected can be taken out of by spiral shell head, and greasy dirt can be stoped to enter receiving groove.The utility model smart structural design, cleaning oil pollution is easy, conveniently causes the dismounting of connecting rod and connecting rod cap, installs, is convenient to carry out full maintenance to motor.Spiral shell head can be fixed on bolt after connecting-rod bolts screw, and with anti-lost, spiral shell head volume is relatively little, after screwing off, is convenient to carry out entirety cleaning.Meanwhile, spiral shell head can also prevent greasy dirt from entering receiving groove.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is screw rod and spiral shell head cooperating structure schematic diagram.
Wherein, 1, hex head bolt head; 2, screw rod; 3, screw section; 4, spiral shell head; 5, protruding; 6, receiving groove; 7, bottom; 8, joint; 9, tapered thread; 10, end cap; 11, elastic claw.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Figure 1-Figure 2, a kind of engine connecting rod bolt, comprises hex head bolt head 1, screw rod 2, screw section 3 and spiral shell head 4; One end of screw rod 2 is provided with hex head bolt head 1, and the other end of screw rod 2 is provided with screw section 3, and the middle part of described screw rod 2 is also provided with protruding 5; The described end face being provided with the screw rod 2 of one end, screw section 3 is also provided with receiving groove 6, described receiving groove 6 comprises bottom 7 and joint 8, joint 8 is provided with tapered thread 9, described tapered thread 9 coordinates with the tapered thread 9 of spiral shell head 4, described spiral shell head 4 comprises the end cap 10, joint 8 and the elastic claw 11 that set gradually, and the length of described elastic claw 11 is greater than the degree of depth of the bottom 7 of receiving groove 6.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
