The utility model discloses further set up to, the quantity of bump is established to three, and is three bump circumference distribute in circle body.

The utility model discloses it is further set up to, three the bump equidistant distribution in circle body.

The utility model discloses further set up as, the height of bump is 0.3-0.5 mm.

The utility model discloses it further sets up to, the quantity of straightway is established to three, and is three straightway circumference distribute in circle body.

The utility model discloses it is further set up to, three the equidistant distribution of straight line section in circle body.

The utility model discloses further set up as, the length of straightway is 2-5 mm.

The utility model discloses further set up to, the bump with circle body is integrated into one piece structure.

The utility model discloses following beneficial effect has: because the supporting role of bump, at the peripheral clearance that forms of bump, make water flow out from the inboard of circle body, because the setting of straightway, make circle body and pipe fitting end form the clearance, make water flow out from the outside of circle body, and then provide an O shape circle, satisfied the compulsory leakage demand when the crimping is not pressed to the card pressure pipe fitting.

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.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

The embodiment of the utility model discloses O shape circle, as shown in fig. 1-3, include: the ring body 1 that is the O shape setting, the inboard of circle body 1 is equipped with at least one bump 2, is equipped with at least one straightway 3 on the circle body 1, and bump 2 is used for water to flow out from circle body 1 inboard, and straightway 3 is used for water to flow out from circle body 1 outside.

It should be noted that, because the supporting action of the salient points 2, a gap is formed around the salient points 2, so that water can conveniently flow out from the inner side of the ring body 1, and because the straight line sections 3 are arranged, the gap is formed between the ring body 1 and the end of the pipe fitting, so that water can conveniently flow out from the outer side of the ring body 1, and further an O-shaped ring is provided, so that the forced leakage requirement when the clamping and pressing pipe fitting is not in compression joint is met.

It should be further noted that, after the pipe fitting is crimped by the crimping tool, the deformation of the pipe fitting is greater than the reserved gap of the O-ring, so that the special shape effect of the O-ring is eliminated, the compression of the O-ring is kept at 25% -30%, the designed sealing performance is achieved, the market demand is met, and the product competitiveness is improved.

As shown in fig. 1 to 3, the number of the salient points 2 is three, and the three salient points 2 are circumferentially distributed on the ring body 1.

As shown in fig. 1-3, three salient points 2 are distributed on the ring body 1 at equal intervals.

As shown in fig. 1, the height of the bump 2 is 0.3-0.5 mm.

As shown in fig. 1, the number of the straight line segments 3 is three, and the three straight line segments 3 are circumferentially distributed in the ring body 1.

As shown in fig. 1-3, three straight line segments 3 are distributed on the ring body 1 at equal intervals. In the specific implementation process, three salient points 2 and three straight line segments 3 are arranged at intervals.

As shown in fig. 1-3, the length of straight segment 3 is 2-5 mm.

As shown in fig. 1-3, the salient point 2 and the ring body 1 are integrally formed.

The working principle is as follows: because the supporting role of bump 2, at the peripheral clearance that forms of bump 2, make things convenient for water to flow out from the inboard of circle body 1, because the setting of straightway 3 makes circle body 1 and pipe fitting end formation clearance, make things convenient for water to flow out from the outside of circle body 1, and then provide an O shape circle, satisfied the compulsory leakage demand when the crimping is not pressed to the card pressure pipe fitting.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
