Abstract
The utility model discloses an oil filling port cap seal ring which comprises a seal ring body with the cross section being round. A circle of grooves are formed in the circumference of the outer side of the seal ring body. Due to the fact that the circle of grooves are formed in the circumference of the outer side of the seal ring body, only small external force is needed to deform the seal ring. Therefore, screwing and loosening the oil filling port cap are enabled to be easy. In addition, due to the fact that the force acted on the seal ring becomes smaller, the seal ring is not prone to fatigue damage, and service life of the seal ring is prolonged.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to the seal ring that a kind of vehicle oil filler covers.
Background technique
At present, at the seal ring that vehicle oil filler covers, generally adopt solid O RunddichtringO.The O RunddichtringO is packed into behind the seal groove, under the effect of external force, resiliently deformable occurs, thereby causes contact to produce seal action at sealing contact surface.Because the O RunddichtringO is solid, must have larger external force that resiliently deformable could occur, this just caused filler cap tighten, very difficult when opening.
Chinese patent notice of authorization number: CN201739495U, notice of authorization day: 2011.02.09, a kind of seal ring is disclosed, comprise the first seal ring and the second seal ring that is used with described the first seal ring, described the first seal ring comprises upper bottom surface, bottom surface, the vertical side that links to each other with described upper bottom surface and the prism that links to each other with described vertical side with described bottom surface; Described the second seal ring comprises the first bottom surface, the second bottom surface, links to each other with described the first bottom surface, the second bottom surface.The sealing circle exists and tightens and open hard problem in use.
The model utility content
The purpose of this utility model is for solution is that hard problem is tightened and opened to the prior art automobile oil filler cap, provide a kind of make filler cap tighten, easy and convenient filler cap seal ring when opening.
The purpose of this utility model is achieved through the following technical solutions.A kind of filler cap seal ring comprises that shape of cross section is circular seal ring body, and the outer circumference face of described seal ring body is provided with a circle groove.Adopt this scheme, because the outer circumference face at the seal ring body is provided with a circle groove, resiliently deformable just can occur in external force seal ring that need only be less, this just so that filler cap tighten, pine lightens when opening, in addition, because the power that acts on the seal ring diminishes, so that the seal ring indefatigability is damaged, prolonged the working life of seal ring.
As preferably, described groove cross section be shaped as U-shaped.This scheme is simple in structure, easily processing.
As preferably, described groove cross section to be shaped as the wide narrow base of oral area trapezoidal.This scheme only needs just to make seal ring generation resiliently deformable with less power, makes to tighten and to open filler cap more easy and convenient.
As preferably, the degree of depth of described groove is 50% to 55% of seal ring body diameter of section, and the width of groove oral area is 35% to 40% of seal ring body diameter of section.If the degree of depth of groove and width are excessive, can reduce the elasticity of seal ring, reduce the voltage endurance capability of seal ring, thereby affect the sealability of seal ring.If the degree of depth of groove and width are too small, also must have larger external force that resiliently deformable could occur, filler cap tighten, still very difficult when opening.This preferred version be one than better suited structure.
The beneficial effects of the utility model are, filler cap tighten, easy and convenient when opening.

Fig. 2 is the sectional view that is installed on the filler cap of the present utility model;
Fig. 3 is plan view of the present utility model;
Fig. 4 is plan view of the present utility model;
Fig. 5 is the utility model embodiment 1 cross-sectional view;
Fig. 6 is the utility model embodiment 2 cross-sectional view.
Embodiment
The below is described in further detail the utility model in conjunction with the accompanying drawings and embodiments:
Embodiment 1: extremely shown in Figure 5 such as Fig. 1, a kind of filler cap seal ring, comprise that shape of cross section is circular seal ring body 2, outer circumference face at seal ring body 2 is provided with a circle groove 4, the shape of cross section of groove 4 is U-shaped, the degree of depth of groove 4 is 50% to 55% of seal ring body 2 diameter of sections, and the width of groove 4 oral areas is 35% to 40% of seal ring body 2 diameter of sections.Seal ring is contained in the root of filler cap 3 screw threads 1, screw thread 1 is connected with filler neck on the vehicle body, the rotation filler cap, seal ring is after being subject to the pressure that screw thread tightens, produce resiliently deformable, play the effect of sealing, resiliently deformable after occuring in seal ring, because being provided with groove at the outer circumference face of seal ring body 2, resiliently deformable just can occur in external force seal ring that need only be less, this with regard to so that filler cap tightening, pine lightens during unlatching, in addition, because the power that acts on the seal ring diminishes, so that the seal ring indefatigability is damaged, prolonged the working life of seal ring.
Embodiment 2: Fig. 6 has provided the another kind of cross-sectional view of seal ring, and other are identical with embodiment 1.The groove sectional shape of this scheme seal ring is the trapezoidal of the wide narrow base of oral area, only needs just can make seal ring generation resiliently deformable with less power, makes to tighten and to open filler cap more easy and convenient.
The above is the better embodiment of the utility model, is not to limit practical range of the present utility model with this.The utility model can also have other embodiment, is C shape such as the sectional shape of seal ring, and only otherwise deviate from spirit of the present utility model, no matter in form what kind of conversion all drops within the protection domain of the present utility model.
