Description
The present invention relates to the locking device that a kind of screw threads for fastening connects.
As everyone knows, the screw threads for fastening connection is widely adopted already as a kind of Placement.However, be connected technical and in use still have some problems up at present this.For example, because vibration is moved back the original very tight nut pine that has twisted; Want one to be screwed into with detaining and to back-out in the disassembly process.The nut pine is withdrawn the membership and causes serious accident, causes personal injury and economic loss; Dismounting inconvenience brings the consumption of time, causes the waste of manpower and materials.
For addressing the above problem, put forward various plans.June 16 nineteen eighty-two, disclosed GB2088985A described a kind of lock nut.This nut has a garden annular resilient thin plate, and its outer garden loop section is fixed on the shoulder of tapped hole of nut one end, and its interior garden loop section camber extends internally, and is removed sub-fraction.When being screwed in this nut on the bolt, said elastic annular thin plate just tightly with the engagement of the external screw thread of bolt, play locking effect by the frictional force between them.Yet the shortcoming that this lock nut exists is, because the existence of annular resilient thin plate is arranged, nut is being screwed into when back-outing, this thin plate is in engagement with external screw thread all the time, and the frictional force when this has increased the nut dismounting undoubtedly wastes time and energy disassemble and assemble work more.In addition, this lock nut does not also reach very reliable degree aspect locking.
One object of the present invention is to provide a kind of novel locking device that is used for the binding thread connection.
Another object of the present invention is to provide a kind of cocksure locking device that binding thread connects that is used for dual locking functions.
Another purpose of the present invention is to provide a kind of binding thread that is used for that can fast assembling-disassembling to connect locking device.
The locking device that is used for the binding thread connection of the present invention is made up of male thread part and female threaded part, is characterized in that male thread part comprises external screw thread body and the locking body of external screw thread with identical screw thread; A garden cylindrical boss is arranged in the end of external screw thread body, a part of/4th of this garden its cross sectional area of cylindrical boss continues to extend upward, form a fan-shaped boss with 1/4th garden post cross-section areas, said garden cylindrical boss and fan-shaped boss are concentric, and the garden heart of the external screw thread of this garden heart and external screw thread body is eccentric; There is post hole, a garden inside of the locking body of external screw thread, this post hole, garden continues to extend upward with the area portions in its half garden, form a post hole with half garden of half area of post hole, garden, post hole, garden and post hole, half garden are concentric, and the garden heart of the external screw thread of this garden heart and the locking body of external screw thread is eccentric; The centripetal moment of two above-mentioned off-centre equates, so that the locking body of external screw thread is assembled on the external screw thread body; An opposite end that has post hole, garden at the locking body of external screw thread has a boss, and vertical outer surface of this boss is the cylinder of positive hexagonal, and this boss also can have the pit of a just interior hexagonal cylinder; Garden cylinder and the corresponding corresponding site on the cylinder of the interior garden in post hole, the garden of the locking body of external screw thread are driven the circular groove in one and half gardens respectively outside the post boss of the garden of external screw thread body, an opening snap ring is contained in this groove, makes the locking body of external screw thread body and external screw thread be assembled into parts; Female threaded part is made up of cover in tapered jacket and the taper; The longitudinal inner surface of tapered jacket is a taper, and vertically outer surface is positive hexagonal cylinder; Vertical outer surface of cover is the taper surface of matching with the longitudinal inner surface of tapered jacket in the taper, on the longitudinal inner surface of cover the female thread that can be meshed with the external screw thread of male thread part is arranged in the taper, and a longitudinal opening is arranged on the wall that overlaps in taper; Prevent that them from relatively rotating but the structure of slide relative, prevents the structure that they are separated from each other in addition but on the conical surface that the inside and outside cover of taper matches, have.
The structure that prevents that the inside and outside cover of taper from relatively rotating but can slide relative can be, vertical inner conical surface of tapered jacket is the interior hexagonal conical surface, and the male cone (strobilus masculinus) of cover is the outer-hexagonal conical surface in the taper, and the inside and outside hexagonal conical surface matches.
The structure that prevents that the inside and outside cover of taper from relatively rotating but can slide relative can be, vertical inner conical surface of tapered jacket is the garden conical surface, three uniform taper boss are set thereon, vertical male cone (strobilus masculinus) of cover is the garden conical surface in the taper, have three uniform taper grooves thereon, and the inside and outside garden conical surface and boss, groove mate with each other.
Prevent that the structure that the inside and outside cover of taper is separated from each other from can be, tapered jacket vertically in the little opening end of the hexagonal conical surface garden cylindrical groove is set, the diameter in this groove garden is greater than the diameter of the little opening end of the interior hexagonal conical surface, so that at shoulder of this place's formation; The smaller diameter end of the vertical outer-hexagonal conical surface that overlaps in taper is provided with one section thin walled structures, after cover installs in the tapered jacket in taper, the thin-walled portion of cover in the taper outwards is out of shape, thereby is lived by the constraint of the shoulder of tapered jacket.
Prevent that the structure that the inside and outside cover of taper is separated from each other from can be, in taper, overlap with vertical taper groove vertically outside the smaller diameter end of the garden conical surface one section thin walled structures is set, after cover installs in the tapered jacket in taper, the thin-walled portion of cover in the taper outwards is out of shape, thereby is lived by the constraint of the shoulder of the taper boss of tapered jacket.
Female threaded part can be a whole female member with vertically outer six sides surface.
Remarkable advantage of the present invention and good effect are, said whole female member is screwed on the said male thread part, its end face is pressed on the surface of fastener tightly, and the external screw thread engagement of the external screw thread body in its a screw thread part and the male thread part, the external screw thread engagement of the locking body of external screw thread in another part and the male thread part, when because vibration or other are former thereby when making described whole female member that loosening tendency be arranged, the female thread of this female member will drive the locking body of external screw thread by frictional force and rotate to the direction that pine moves back female member, because the center of rotation of the locking body of external screw thread and the center of external screw thread are eccentric, its turning radius is greater than the radius of external screw thread, at this moment, the moon in female member and external screw thread anti-release member, have great extruding force to produce at the maximum turning radius of the locking body of external screw thread place between the external screw thread, this extruding force will stop the female member pine to move back in the frictional force that garden Zhou Fangxiang is brought definitely effectively.
