Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
The utility model cap structure, as shown in Figure 1, 2, comprise and the cutting graftage part 2 of oil filler 6 adaptation and the cap 1 be located on cutting graftage part 2, side, cutting graftage part 2 is provided with Elastic buckle 4; As shown in Figure 3, Elastic buckle 4 upper end is connected with cutting graftage part 2, is provided with gap between dual-side and cutting graftage part 2, and bottom is provided with the fixture block 41 of protrusion; As shown in Figure 4, oil filler 6 bottom surface is provided with the spiral chute 61 coordinating clamping with fixture block 41.
Elastic buckle 4 is provided with symmetrical two, and spiral chute 61 is provided with two with the clamping of fixture block 41 difference phase.As shown in Figure 2, can be regarded as on cutting graftage part 2, to be provided with two symmetrical flutings, Elastic buckle 4 is placed in fluting, Elastic buckle 4 width is slightly less than the groove width of cutting graftage part 2, therefore leave certain gap between Elastic buckle 4 and cutting graftage part 2, to protect Elastic buckle, there is certain elastic telescopic, be convenient to stretch.
In order to better sealing, upper end, cutting graftage part 2 be provided with the mounting groove 3 installing seal ring 5.O type circle selected by seal ring 5, seal ring 5 internal diameter is slightly less than the external diameter of cap mounting groove, guarantee that seal ring 5 and oil filler are stamped certain magnitude of interference, by rotation ensure seal ring that oil filler covers along valve chamber cover downwards and oil filler wall effectively compress, to reach sealing effect, ensure that oil can not ooze out between seal ring 5 and cap.
As shown in Figure 5, the upper-end surface of oil filler 6 is provided with the flange 62 of protrusion, and cap 1 is also provided with bump.When cap is tightened, these two flanges 62 are just in time corresponding with protuberance, can play and tighten mark action, user can be pointed out to tighten position, more convenient use, shorten the installation time.Cap 1 is also provided with the adjustment lever 11 being convenient to turn, conveniently tightens or take off.For the ease of opening and installing, adjustment lever 11 can be distributed in the same direction with symmetrical Elastic buckle 4.
Cutting graftage part 2 of the present utility model and oil filler are tubular body structure, play certain leading role, are convenient to grafting.Cutting graftage part 2, cap 1 and Elastic buckle 4 are the integral structure of molding and forming.
As shown in Figure 6,7, the assembling condition of cap and oil filler, fixture block 41 comprises end face 411 and side 412, spiral chute 61 helically structure, is convenient to tighten and turn on.Under being in tight condition, the end face 411 of fixture block 41 fits with the end face of spiral chute 61, and side 412 fits with the sidewall 611 of spiral chute 61.After cap is tightened, the end face 411 on fixture block 41 coordinates with end face at the end of the spiral chute 61 of valve chamber cover oil filler bottom surface, and guarantee is axially tightened fixing.The side 412 of fixture block 41 coordinates with the sidewall 611 of valve chamber cover oil filler spiral chute 61, ensures that circumference is tightened fixing.In like manner, the end face that the end face 411 of another fixture block 41 and side 412 are also corresponding with the spiral chute 61 of valve chamber cover oil filler bottom surface respectively and side-fit, ensure that the axial and circumferential of cap are tightened further.When need take off, counterrotating can discharge fixture block 41, takes off cap.
Cap divides two-part: top is cap 1, and bottom is the cutting graftage part 6 of tubulose; Upper end, cutting graftage part 2 is provided with the mounting groove 3 of seal ring 5, symmetrical Elastic buckle 4 on the cutting graftage part 6 that mounting groove 3 is downward, oil filler 6 bottom surface is provided with two sections of spiral chutes 61, when cap is tightened by the rotation of axially downward power, the fixture block 41 of Elastic buckle 4 coordinates clamping with the spiral chute 61 of valve chamber cover oil filler 6 bottom surface, ensures that the axial and circumferential of oil filler are tightened.Seal ring 5 coordinates with valve chamber cover oil filler inwall the effect playing sealing.
The utility model cap structure, establishing in the side of cutting graftage part 2 can the Elastic buckle 4 of elastic telescopic, when cap is by when axially downward power inserts oil filler 6, inwardly shrink by oil filler 6 inner wall pressure, coordinate clamping when arrival bottom does not stress to eject with spiral chute 61, ensure that cap axial and circumferential are tightened fixing; Seal ring 5 coordinates with the inwall of valve chamber cover oil filler 6 effect playing sealing.Owing to adopting Elastic buckle 4 to coordinate with the spiral chute 61 bottom oil filler 6, only need simple and quick rotation angle just can ensure effective sealing, structure is simple, and installing/dismounting is convenient, has stronger practicability.
By reference to the accompanying drawings the utility model is exemplarily described above; but the utility model is not limited to aforesaid way; as long as adopt method of the present utility model is conceived and technological scheme is carried out the improvement of various unsubstantialities or directly apply to other occasion, all drop in protection domain of the present utility model.
