Abstract
The utility model relates to a nut, in particular to a nut provided with a sealing ring. The nut provided with the sealing ring comprises a nut and is characterized in that the nut is in the shape of a step; the outer layer of the step is an oblate ring, the middle layer of the step is a sawtooth ring and the inner layer of the step is a fine and circular ring; the oblate ring, the sawtooth ring and the fine and circular ring are superposed as one concentrically; the inner circumferences of the oblate ring and the sawtooth ring are equal and provided with internal threads, the inner circumference of the fine and circular ring is larger, and a step is formed between the larger circumference and the smaller circumferences, a sealing ring is arranged on the step; the inner circumference of the fine and circular ring is provided with a turned edge that compresses the sealing ring on the step; and the sealing ring is a rubber product or a plastic product. As the sealing ring is arranged on the nut, the sealing ring can closely cling to the external thread of the bolt when the nut is screwed into the bolt and is tightly screwed on a connected part. Besides, the sealing ring can be tightly pressed on the surface of the part, thereby achieving better sealing effect.
Description
Technical field
The utility model is a kind of nut, particularly a kind of nut that is provided with seal ring.
Background technique
Nut is a kind of link that is used with bolt, has outside thread on the bolt, has internal thread on the nut, screw bolt and nut is used to be fastenedly connected two parts that have through hole, this Connecting format claims bolt to connect, and is more firm for bolt is connected, so all be furnished with pad on the bolt.In many actual conditionss, it is more firm not only to need bolt to connect, and has good sealability but also need bolt to connect.Existing bolt connects can be very firm, but sealability is very poor.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of existing its poor sealing performance of bolt connecting device, to invent a kind of nut that is provided with seal ring.
The purpose of this utility model realizes as follows: the described nut that is provided with seal ring, comprise a nut, it is characterized in that: nut is step-like, the skin of this step is oblate ring, the middle level is a saw-tooth ring, nexine is a fine circle, oblate ring, saw-tooth ring and fine circle are concentric is superimposed on one, the inner circumferences of wherein oblate ring and saw-tooth ring etc. are big, which is provided with internal thread, and the inner circumference of fine circle is bigger, make and form a step between big circumference and small circumference, be provided with seal ring on this step, the inner periphery of fine circle is provided with a crimping, and crimping is pressed on seal ring on the step.
Described seal ring is rubber product or plastic article.
Good effect of the present utility model is as follows: because nut is provided with seal ring, so when this nut is screwed into bolt and is tightened on the connected part, seal ring can be fitted on the outside thread of bolt closely, and seal ring can be pressed in the surface of part closely, reaches better sealing effect.
Description of drawings
Fig. 1 is the utility model structural drawing
Among the figure: nut 1, oblate ring 2, saw-tooth ring 3, fine circle 4, internal thread 5, seal ring 6, crimping 7.
Embodiment
As shown in Figure 1, the described nut that is provided with seal ring, comprise a nut 1, it is characterized in that: nut 1 is step-like, the skin of this step is oblate ring 2, the middle level is a saw-tooth ring 3, nexine is a fine circle 4, and oblate ring 2, saw-tooth ring 3 and fine circle 4 are concentric is superimposed on one, and the inner circumference of wherein oblate ring 2 and saw-tooth ring 3 etc. are big, which is provided with internal thread 5, the inner circumference of fine circle 4 is bigger, makes to form a step between big circumference and small circumference, is provided with seal ring 6 on this step, the inner periphery of fine circle 4 is provided with a crimping 7, and crimping 7 is pressed on seal ring 6 on the step.
Described seal ring 6 is rubber product or plastic article.The good effect of this technological scheme is that seal ring can be fitted on the outside thread of bolt closely, and is pressed in connected part surface closely, reaches better sealing effect.
During use, this nut is screwed into bolt and is tightened on the connected part, because nut is provided with seal ring, so seal ring can be fitted on the outside thread of bolt closely, and seal ring can be pressed in the surface of part closely, reached better sealing effect.
