The novel sealing device comprises a lock bolt, a rubber sealing body and a broaching nut matched with the lock bolt, wherein the rubber sealing body is provided with a through hole, the lock bolt penetrates through the through hole, and the rubber sealing body is arranged between the bolt head of the lock bolt and the broaching nut.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of new type sealing device that the nose end mouth is sealed.
Background technique
At present generally adopt the parts such as Bowl Plug, conical plug, plug, steel ball to seal for the sealing of hole end surface on the component, this needs Sealing cooperating with the hole when hole sealed, to strict fit tolerance requirement is arranged between Sealing and the hole; It is not good that no person easily produces sealing effect, causes the problems such as leakage, and this preparation process that has just increased Sealing requires and cost of production.For example, China Patent Publication No. CN201095597, open day on August 6th, 2008, the name of innovation and creation is called sealing plug, this application case discloses a kind of sealing plug, the bottom of described sealing plug vertically is provided with at least two frustum structures, and described sealing plug bottom frustum structure sharp edge falls radius≤0.2.When the sealing plug of this scheme cooperates with the hole, same to strict fit tolerance requirement is arranged between Sealing and the hole.
On the other hand, present Sealing cooperates with the hole when hole sealed, and in order to improve sealing effect, usually requires seal surface is coated with sealer; But for oil channel sealing, scribble the Sealing of sealer, can bring oil contamination, reduce the quality of fluid.
The model utility content
The first purpose of the present utility model is in order to overcome existing Sealing when the hole is sealed, to strict fit tolerance requirement is arranged between Sealing and the hole, the preparation process requirement of Sealing and the problem of cost of production can have been increased, provide a kind of and can reduce the preparation process requirement, and then reduce production costs, and the new type sealing device of good sealing effect.
The second purpose of the present utility model is to be coated with sealer in order to improve sealing effect in seal surface in order to overcome existing Sealing, but sealer brings pollution can for the fluid in the oil duct, reduce the problem of Oil Quality, a kind of good sealing effect is provided, and can bring to the fluid in the oil duct new type sealing device of pollution.
The technical solution of the utility model is:
A kind of new type sealing device is located in the hole and is used for the closed hole port, comprises lock bolt, rubbery sealed body and the extruding nut that cooperates with lock bolt; Described rubbery sealed body is provided with a through hole, and described lock bolt passes this through hole; Rubbery sealed body is located between the bolt head and extruding nut of lock bolt.The seal arrangement of this programme is as follows to the sealing means that the nose end mouth seals: by tightening lock bolt, bolt head and extruding nut are pushed rubbery sealed body, make the rubber seal volumetric expansion, form reliably sealing between rubbery sealed body and the hole wall thereby make; In addition, the seal arrangement of this programme can also be different according to the pressure demand in the hole, adjust the dynamics that screws of lock bolt, reach good sealing effect.The seal arrangement of this programme is not to there being strict fit tolerance requirement between rubbery sealed body and the hole, even gapped between rubbery sealed body and the hole, can realize sealing to the nose end mouth and good sealing effect by tightening lock bolt too; Can greatly reduce the preparation process requirement of rubbery sealed body like this, and then reduce production costs.On the other hand, the seal arrangement of this programme does not need to be coated with sealer when sealing, just can reach good sealing effect, therefore can not bring pollution to the fluid in the oil duct.
As preferably, it is cylindric that rubbery sealed body is, and described through hole is circular hole and coaxial being located in the rubbery sealed body of through hole.
As preferably, the side of rubbery sealed body is provided with some annular protrusions coaxial with rubbery sealed body.At the rubber seal body side surface annular protrusion is set, when tightening lock bolt, in identical extruding force situation, can increases the dilatancy amount of annular protrusion, and then improve sealing effect.
As preferably, the lower surface of bolt head is a plane.The lower surface of bolt head is the end face that matches with the rubbery sealed body end face, and the lower surface of bolt head is a plane, can make and form good sealing between the lower surface of bolt head and the rubbery sealed body end face.
As preferably, be provided with a boss in the middle part of the end face of extruding nut, end face middle part relative with the extruding nut on the described rubbery sealed body is provided with first groove corresponding with boss.At the extruding nut when cooperating with rubbery sealed body, the boss that pushes nut end face can be embedded in first groove of end face of rubbery sealed body; When the operator tightened lock bolt, boss can push the first groove floor, and the end face that pushes simultaneously nut also can push the end face of rubbery sealed body; So that rubbery sealed body when being subjected to same extruding force, can increase the outside dilatancy amount of rubbery sealed body, strengthen the sealing effect between rubbery sealed body and the hole like this.On the other hand, the first groove arranges the consumption that can also reduce rubber, reduces cost.
As preferably, end face middle part relative with bolt head on the rubbery sealed body is provided with second groove corresponding with bolt head.The setting of the second groove not only can reduce consumption, the reduction cost of rubber; Can also so that bolt head sinks in the second groove, avoid forming in the exterior edge face of rubbery sealed body the bolt head of projection.
The beneficial effects of the utility model are: have good sealing effect, the preparation process requirement is low, cost of production is low, and can not bring to the fluid in the oil duct characteristics of pollution.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model embodiment 1.
Fig. 2 is a kind of structural representation of the utility model embodiment 2.
Among the figure: lock bolt 1, rubbery sealed body 2, extruding nut 3, step hole 4, annular protrusion 5.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Embodiment 1: as shown in Figure 1, a kind of new type sealing device comprises lock bolt 1, rubbery sealed body 2 and the extruding nut 3 that cooperates with lock bolt.Rubbery sealed body 2 is cylindric, and rubbery sealed body is provided with a through hole.Through hole is circular hole and coaxial being located in the rubbery sealed body of through hole.Described lock bolt 1 passes this through hole; Rubbery sealed body 2 is located between the bolt head and extruding nut of lock bolt.End face middle part relative with bolt head on the rubbery sealed body 2 is provided with second groove corresponding with bolt head.The lower surface of described bolt head is a plane, and this plane and the second groove floor fit.The one end face middle part of extruding nut is provided with a boss, and end face middle part relative with the extruding nut on the described rubbery sealed body is provided with first groove corresponding with boss.
The seal arrangement of the present embodiment is as follows to the sealing means that the nose end mouth seals: at first, the optimum structure in the hole that cooperates with the seal arrangement of this programme is the step hole 4 that the port in hole is provided with step, as shown in Figure 1.Then, will push nut and place on the step, and by tightening lock bolt, bolt head and extruding nut be pushed to rubbery sealed body, make the rubber seal volumetric expansion, form reliably sealing between rubbery sealed body and the hole wall thereby make.On the other hand, the seal arrangement of this programme can also be different according to the pressure demand in the hole, adjust the dynamics that screws of lock bolt, reach good sealing effect.
