(II) technical scheme

The utility model discloses a following technical scheme realizes: the utility model provides a heavy automobile engine fender, including plate body and sealing ring pad, from having card limit and fabrication hole on the plate body, the shaping of four corners department has the counter sink on the plate body, the counter sink include counter sink groove and shaping in the via hole at counter sink groove lower extreme middle part, the counter sink inslot is provided with the sealing ring pad, the shaping is fluted on the peripheral lateral wall of sealing ring pad, the middle part shaping has the trepan boring in the sealing ring pad.

Through adopting above-mentioned technical scheme, the counter sink the seal ring pad and the design of recess can compensate the clearance between outside bolt and the plate body when this fender installation, prevents the infiltration of muddy water outside bolt mounted position in the use at this fender, has avoided getting rusty between outside bolt and this fender for the dismantlement of this fender is more convenient, and the maintenance of this fender of being convenient for, and the practicality is good.

Furthermore, the sealing ring gasket is bonded with the countersunk groove, and is made of rubber.

By adopting the technical scheme, the sealing ring gasket can be reliably fixed.

Further, the outer diameter of the sealing ring gasket is slightly smaller than the outer diameter of the countersunk head groove, and the thickness of the sealing ring gasket is slightly smaller than the height of the countersunk head groove.

Through adopting above-mentioned technical scheme, can make this fender when the installation, outside bolt fastening inseparabler.

Further, the size of the annular ring is the same as that of the via hole.

Through adopting above-mentioned technical scheme, can make outside bolt pass to realize the convenient installation of this fender.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

for there is the clearance between the fastening bolt of solving current heavy automobile engine fender installation and the fender, get into the clearance and cause the rust between fastening bolt and the fender because of muddy water easily, make fastening bolt dismantle comparatively inconvenient, increase the problem of the fender later stage maintenance degree of difficulty, the utility model discloses a counter sink, the design of seal ring pad and recess, clearance between outside bolt and the plate body when can compensateing this fender installation, prevent the infiltration of muddy water outside bolt mounted position in the use at this fender, avoided getting rusty between outside bolt and this fender, make the dismantlement of this fender more convenient, the maintenance of this fender of being convenient for, the practicality is good.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-4, the fender of the heavy-duty car engine in this embodiment includes a plate body 1 and a sealing ring pad 3, the plate body 1 has a clamping edge and a fabrication hole, so as to facilitate the pre-positioning of the plate body 1 during the installation, a countersunk hole 2 is formed at the four corners of the plate body 1, the countersunk hole 2 includes a countersunk groove 7 and a via hole 5 formed at the middle of the lower end of the countersunk groove 7, the sealing ring pad 3 is disposed in the countersunk groove 7, a groove 4 is formed on the peripheral sidewall of the sealing ring pad 3, a ring hole 6 is formed at the middle of the sealing ring pad 3, the design of the countersunk hole 2, the sealing ring pad 3 and the groove 4 can compensate the gap between the external bolt and the plate body 1 during the installation of the fender, prevent the penetration of muddy water to the installation position of the external bolt during the use of the fender, avoid the rusting between the external bolt and the fender, and make the disassembly of the fender, the maintenance of this fender of being convenient for, the practicality is good.
