Description

A kind of nut with seal groove
Technical field
This utility model relates to nut technical field, particularly relates to a kind of nut with seal groove.
Background technology
Nut generally with bolt with the use of, play the effect connecting fastening parts, lock using screw bolt and nut to coordinate During tight parts, in order to prevent loosening of nut, general first overlap on bolt after spring sealed packing ring again nut at spiral shell On bolt, rely on the elastic force of spring sealed packing ring to the frictional force increasing between nut and bolt, and then play and prevent nut loosening With the purpose sealed, but, owing to spring sealed packing ring is during using for a long time, the position of spring sealed packing ring is easily sent out Raw change, thus affect the sealing property of elastic seal ring.
Utility model content
The purpose of this utility model is to provide a kind of nut with seal groove, to solve proposition in above-mentioned background technology Problem.
The technical scheme that this utility model relates to:
A kind of nut with seal groove, by nut body, male member, groove, cannelure, elastic seal ring A, elasticity Sealing ring B, screwed hole, convex tendon, back-off part, chamfering A, chamfering B form.
Described nut body is provided with screwed hole.
One axial end of described nut body is provided with male member, and the other end of male member opposing nut body is provided with back-off Part.
Offer an annular groove on the inwall of described screwed hole, elastic seal ring B is installed in groove.
Offer cannelure on the lower surface of described nut body, elastic seal ring A is installed in cannelure.
Preferably, the top edge of described screwed hole is provided with chamfering A, and the lower limb of screwed hole is provided with chamfering B.
Preferably, the cross section of described groove is rectangle.
Preferably, the cross section of described cannelure is rectangle.
Compared with prior art, the beneficial effects of the utility model are: this has a nut of seal groove, simple in construction, set Meter rationally, by offering groove, is provided with elastic seal ring B in groove, increases by the elastic force of elastic seal ring B Nut matches with bolt the frictional force between screw thread, and then prevents the loosening, by offering cannelure, in annular of nut Elastic seal ring A is installed, it is possible to prevent the position of elastic seal ring A from producing dislocation, be effectively improved its sealing property in groove.
Accompanying drawing explanation
Fig. 1 is this utility model sectional structure schematic diagram when being fitted without elastic seal ring.
Fig. 2 is this utility model sectional structure schematic diagram when being mounted with elastic seal ring.
In figure: 1. nut body, 2. male member, 3. groove, 4. cannelure, 5. elastic seal ring A, 6. elastic seal ring B, 11. screwed holes, 12. convex tendons, 21. back-off parts, 111. chamferings A, 112. chamferings B.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of nut with seal groove, by nut body 1, male member 2, recessed for this utility model Groove 3, cannelure 4, elastic seal ring A5, elastic seal ring B6, screwed hole 11, convex tendon 12, back-off part 21, chamfering A111, Chamfering B112 forms.
Described nut body 1 is provided with screwed hole 11.
One axial end of described nut body 1 is provided with male member 2, the other end of male member 2 opposing nut body 1 It is provided with back-off part 21.
Offering an annular groove 3 on the inwall of described screwed hole 11, the cross section of groove 3 is rectangle, at groove 3 Elastic seal ring B6 is inside installed, by offering groove 3, elastic seal ring B6 is installed in groove 3, close by elasticity The elastic force of seal B6 increases the frictional force that nut matches between screw thread with bolt, and then prevents loosening of nut.
Offering cannelure 4 on the lower surface of described nut body 1, the cross section of cannelure 4 is rectangle, at cannelure 4 Elastic seal ring A5 is inside installed, by offering cannelure 4, elastic seal ring A5 is installed in cannelure 4, it is possible to be anti- Only the position of elastic seal ring A5 produces dislocation, is effectively improved its sealing property.
The top edge of described screwed hole 11 is provided with chamfering A111, and the lower limb of screwed hole is provided with chamfering B112, convenient Nut twists such as to enter in bolt.
Compared with prior art, the beneficial effects of the utility model are: this has a nut of seal groove, simple in construction, set Meter rationally, by offering groove 3, is provided with elastic seal ring B6 in groove 3, comes by the elastic force of elastic seal ring B6 Increase nut to match with bolt the frictional force between screw thread, and then prevent loosening of nut, by offering cannelure 4, Elastic seal ring A5 is installed in cannelure 4, it is possible to prevent the position of elastic seal ring A5 from producing dislocation, be effectively improved Its sealing property.
