Referring to fig. 1 to 4, an embedded anti-loosening fixing assembly disclosed in this embodiment includes a first cylindrical anti-loosening assembly 1 and a second cylindrical anti-loosening assembly 2. Wherein, a first external thread 3 is formed on the circumferential surface of the first cylindrical anti-loosening component 1, a first chamfer surface 4 and a second chamfer surface 5 are formed on one end surface of the first cylindrical anti-loosening component 1, and the first chamfer surface 4 and the second chamfer surface 5 are arranged in an included angle; a second external thread 6 is formed on the circumferential surface of the second cylindrical anti-loosening component 2, and the helix angle of the second external thread 6 is the same as that of the first external thread 3; a third chamfer 7 and a fourth chamfer 8 are formed on one end face of the second cylindrical anti-loosening component 2, and the third chamfer 7 and the fourth chamfer 8 are arranged at an included angle; when one end face of the first cylindrical anti-loosening component 1 is abutted against one end face of the second cylindrical anti-loosening component 2, the first chamfer 4 is abutted against the third chamfer 7, and the second chamfer 5 is abutted against the fourth chamfer 8; in this embodiment, the angle between the first chamfer 4 and the horizontal plane is larger than the lead angle of the first external thread 3. Because the included angle between the bevel and the horizontal plane is larger than the helix angle of the screw thread, the mechanical equipment is insufficient to drive the lower first cylinder anti-loosening component 1 to rotate simultaneously by friction force in the vibration process; the second cylindrical anti-loosening assembly 2 is blocked because the included angle is larger than the helix angle of the screw thread in the unscrewing process, the purpose that the screw cannot be rotated and lifted is achieved, and the effect that the whole embedded anti-loosening fixing assembly cannot be loosened is achieved.
It should be noted that the angle between the first chamfer 4 and the horizontal plane is the same as the angle between the second chamfer 5 and the horizontal plane; the first chamfer surface 4 and the second chamfer surface 5 are arranged in a crossing way, and the crossing line of the first chamfer surface 4 and the second chamfer surface 5 passes through the central line of the first cylindrical locking component 1 and the second cylindrical locking component 2. When one end surface of the first cylindrical locking component 1 is abutted against one end surface of the second cylindrical locking component 2, the ends of the first external thread 3 and the second external thread 6 are abutted against each other. Of course, in other embodiments, the angle of the two chamfer surfaces may be set differently, and the purpose of the present application may be achieved by only ensuring that the included angle between one of the chamfer surfaces and the horizontal plane is larger than the lead angle of the first external thread 3. Of course, the first chamfer 4 and the second chamfer 5 are arranged in a crossed mode, and the intersecting line of the first chamfer 4 and the second chamfer 5 passes through the center line of the first cylindrical anti-loosening assembly 1 and the center line of the second cylindrical anti-loosening assembly 2, so that the whole assembly can be machined simply and easily, the integrity is strong after installation, the stress is stable, and the structural stability and durability are high.
Further, the embedded anti-loosening fixing assembly of the embodiment further comprises a nested column 9, a first nested hole is formed in the middle of the first cylindrical anti-loosening assembly 1, and a second nested hole is formed in the middle of the second cylindrical anti-loosening assembly 2; when one end face of the first cylindrical anti-loosening component 1 is abutted against one end face of the second cylindrical anti-loosening component 2, the first nesting hole is communicated with the second nesting hole; the nesting posts 9 are operatively inserted into the first nesting holes and the second nesting holes; and part of the peripheral surface of the nesting column 9 is abutted against the inner surfaces of the first nesting hole and the second nesting hole.
In this embodiment, the cross section of the nesting column 9 is an equilateral triangle, and of course, the cross section of the nesting column 9 can be set to be any non-circular according to actual needs, and only the first nesting hole and the second nesting hole and the cross section are required to be matched with the cross section of the nesting column 9, so that when the nesting column 9 is inserted into the first nesting hole and the second nesting hole, the first cylindrical locking assembly 1 and the second cylindrical locking assembly 2 can be driven to synchronously rotate by the nesting column 9. Then, when the torque is applied to the sleeve column 9 anticlockwise to unscrew, the first cylindrical anti-loosening assembly 1 and the second cylindrical anti-loosening assembly 2 can be driven to synchronously rotate in the unscrewing process, so that the whole embedded anti-loosening fixing assembly is unscrewed, and the embedded anti-loosening fixing assembly is convenient to detach and reuse.
Further, referring to fig. 5 to 7, the side surface of the nest post 9 of the present embodiment is formed with a vent groove 10, and the vent groove 10 penetrates in the longitudinal direction of the nest post 9. The bottom of the nested column 9, which is located at the exhaust slot 10, is also formed with a chamfer 11. Through setting up exhaust duct 10, no matter screw up or screw up the in-process of loosening, embedded locking fixed subassembly is at the in-process of screwing in embedded silk groove, does not receive the resistance of silk inslot air pressure, and available nested post 9 inserts first nested hole and second nested hole, makes first nested hole screw up the in-process of loosening and the synchronous commentaries on classics of second nested hole, and reaches the purpose of unscrewing whole embedded locking fixed subassembly and overhauling or changing.
It is easy to understand that the specification parameters of the second external thread 6 of the present embodiment are the same as those of the first external thread 3; specification parameters include outer diameter, inner diameter, pitch, lead, and profile angle. And the length of the first cylindrical anti-loosening component 1 is half of that of the second cylindrical anti-loosening component 2.
The embedded locking fixed subassembly effect of this embodiment lies in:
the lead angle of the second external thread 6 of the present application is the same as the lead angle of the first external thread 3; when one end face of the first cylindrical anti-loosening component 1 is abutted against one end face of the second cylindrical anti-loosening component 2, the first chamfer 4 is abutted against the third chamfer 7, and the second chamfer 5 is abutted against the fourth chamfer 8; the included angle between the first chamfer 4 and/or the second chamfer 5 and the horizontal plane is larger than the helix angle of the first external thread 3, so that the included angle between the chamfer and the horizontal plane is larger than the helix angle of the thread, and the mechanical equipment is insufficient to drive the lower first cylinder anti-loosening component 1 to rotate simultaneously by friction force in the vibration process; the second cylindrical anti-loosening assembly 2 is blocked because the included angle is larger than the helix angle of the screw thread in the unscrewing process, the purpose that the screw cannot be rotated and lifted is achieved, and the effect that the whole embedded anti-loosening fixing assembly cannot be loosened is achieved.
