Abstract

The utility model discloses a kind of sealing nut, it comprises nut body and seal ring, the inner side of the afterbody of described nut body is dug and is agreed with groove for what install seal ring, and the ring of seal ring is thick is greater than the degree of depth of agreeing with groove, and described seal ring is provided with the internal thread consistent with the internal thread of nut body.Have the following advantages: seal ring and nut body adopt integrated sealing shaping, seal easier, sealing effect is more stable; The ring of seal ring is thick is greater than the degree of depth of agreeing with groove, i.e. some is outside exposed in the end of seal ring, nut install fastening after, the exposed part in nut outside of seal ring is extruded, and plays the seal action of rubber seal principle; Have additional the internal thread the same with nut at seal ring, further increase sealing effect, and easy extrusion-deformation when effectively prevent application O RunddichtringO, the Problem of Failure such as to break.

Description

A kind of sealing nut
Technical field
The utility model relates to a kind of sealing nut.
Background technique
In prior art, most final controlling element producer is that nut adds the sealing of O RunddichtringO.Easy squeezed distortion in O RunddichtringO installation process, the Problem of Failure such as to break, and then cause seal failure.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of sealing easier, reliable sealing nut.
For solving the problems of the technologies described above, a kind of sealing nut that the utility model provides, it comprises nut body and seal ring, the inner side of the afterbody of described nut body is dug and is agreed with groove for what install seal ring, the ring of seal ring is thick is greater than the degree of depth of agreeing with groove, and described seal ring is provided with the internal thread consistent with the internal thread of nut body.Seal ring and nut body adopt integrated sealing shaping, and seal easier, sealing effect is more stable; The ring of seal ring is thick is greater than the degree of depth of agreeing with groove, i.e. some is outside exposed in the end of seal ring, nut install fastening after, the exposed part in nut outside of seal ring is extruded, and plays the seal action of rubber seal principle; Have additional the internal thread the same with nut at seal ring, further increase sealing effect, and easy extrusion-deformation when effectively prevent application O RunddichtringO, the Problem of Failure such as to break.
As preferably, described in agree with groove and comprise circular groove, annular boss and mounting groove, described annular boss is between circular groove and mounting groove, and circular groove is positioned at the port of nut body afterbody, and the internal diameter of mounting groove is greater than the internal diameter of circular groove; Described seal ring exterior edge face offers groove, and the part being positioned at groove both sides is respectively the first boss and the second boss; First boss and circular groove shape cooperatively interact, and groove and annular boss shape cooperatively interact, and the second boss and mounting groove shape cooperatively interact.Be fixed on by seal ring in nut body, this structure is simple, easy for installation.
After adopting above structure, a kind of sealing nut of the present utility model compared with prior art, has the following advantages:
(1) seal ring and nut body adopt integrated sealing shaping, and seal easier, sealing effect is more stable;
(2) nut install fastening after, the exposed part in nut outside of seal ring is extruded, and plays seal action;
(3) have additional the internal thread the same with nut at seal ring, further increase sealing effect, and easy extrusion-deformation when effectively prevent application O RunddichtringO, the Problem of Failure such as to break;
(4) structure is simple, seals easier.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model nut body structural representation;
Fig. 3 is the utility model ring structure schematic diagram.
Wherein: 1, nut body, 1.1, circular groove, 1.2, annular boss, 1.3, mounting groove, 2, seal ring, 2.1, groove, the 2.2, first boss, the 2.3, second boss, 3, internal thread.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of sealing nut that the present embodiment provides, it comprises nut body 1 and seal ring 2, the inner side of the afterbody of described nut body 1 is dug and is agreed with groove for what install seal ring 2, the ring of seal ring 2 is thick is greater than the degree of depth of agreeing with groove, and described seal ring 2 is provided with the internal thread 3 consistent with the internal thread of nut body 1.
As Figure 2-3, the described groove that agrees with comprises circular groove 1.1, annular boss 1.2 and mounting groove 1.3, described annular boss 1.2 is between circular groove 1.1 and mounting groove 1.3, and circular groove 1.1 is positioned at the port of nut body afterbody, and the internal diameter of mounting groove 1.3 is greater than the internal diameter of circular groove 1.1; Described seal ring 2 exterior edge face offers groove 2.1, and the part being positioned at groove 2.1 both sides is respectively the first boss 2.2 and the second boss 2.3; First boss 2.2 cooperatively interacts with circular groove 1.1 shape, and groove 2.1 and annular boss 1.2 shape cooperatively interact, and the second boss 2.3 and mounting groove 1.3 shape cooperatively interact.
Seal ring uses 90 ° of shore hardness A rubber materials, also according to actual client's varying environment demand, can change the rubber materials such as other are corrosion-resistant, high-low temperature resistant.
