As shown in fig. 1 to 6, a lock bolt locking structure according to an embodiment of the present invention includes a body 1, a lock nut 3, and a lock member 4; the body 1 is a cylinder; one end of the body 1 is fixedly provided with a first end component 2; one side of the first end member 2 facing the body 1 is of a plane structure; the end member I2 is provided with a clamping structure I for clamping a tool; preferably, the first clamping structure is an outer hexagon or an inner hexagon, so that a common wrench can be used for clamping operation. In the embodiment, the body 1 and the end member one 2 are preferably integrally arranged, so that the structure is reliable and the processing is convenient.
The body 1 is provided with an external thread; the external thread is matched with the locking nut 3. The external thread covers the whole or part of the body 1.
The other end of the body 1 is provided with a threaded hole 1-1; the threaded hole 1-1 is coaxial with the body 1; the thread direction of the threaded hole 1-1 is opposite to the direction of the external thread, so that the loosening rotating direction of the locking nut 3 is opposite to that of the locking member 4, and when the locking member 4 and the locking nut 3 are tightly pressed through the blocking assembly 5, the locking nut 3 and the locking member 4 are not easy to rotate, so that the locking nut is not loosened.
The opening part of the threaded hole 1-1 is a taper hole structure 1-2; the taper hole structure 1-2 is provided with an annular groove 1-3; the annular groove 1-3 and the taper hole structure 1-2 are in smooth transition so that the annular bulge 4-11 can be easily entered.
The other end of the body 1 is divided into two fan-shaped ring structures 1-4; the two fan ring body structures 1-4 are symmetrically arranged by the central line of the body 1, so that the fan ring body structures 1-4 can be jacked outwards by the annular bulges 4-11 along the radial direction, and generate proper elastic deformation, and the looseness of the locking nut 3 can be effectively limited.
The locking nut 3 can be matched with the external thread and is connected with the external thread through the thread so as to lock the equipment needing to be locked on the body 1.
The loosening prevention member 4 includes: a screw 4-1 and an end member II 4-2; the second end component 4-2 is fixedly arranged at one end of the screw rod 4-1; in the present embodiment, the side of the second end member 4-2 facing the body 1 is preferably a plane structure to be pressed in contact with the lock nut 3 or the barrier assembly 5. The end component II 4-2 is provided with a clamping structure II for clamping a tool. The second clamping structure is an outer hexagon or an inner hexagon so as to facilitate clamping operation of a common wrench. And the first clamping structure and the second clamping structure are preferably the same in structure, so that the operation of an operator is facilitated.
A baffle component 5 can be selectively arranged between the second end component 4-2 and the locking nut 3; the blocking component 5 is sleeved on the body 1, one end of the blocking component 5 is propped on the locking nut 3, and the other end of the blocking component 5 is propped on the end member II 4-2; when the jam nut 3 is at the end of the body 1, the second end member 4-2 may be pressed directly against the jam nut 3, i.e. without the barrier assembly 5.
Preferably, the baffle assembly 5 includes: the clamping sleeve and the elastic gasket; the cutting sleeve is sleeved on the body 1; one end of the clamping sleeve is arranged on the locking nut 3; the elastic gasket is sleeved on the body 1 and positioned between the other end of the clamping sleeve and the second end member 4-2, so that the phenomenon that the locking member 4 and the locking nut 3 are not pressed tightly due to deformation caused by expansion with heat, contraction with cold and the like between the locking member 4 and the locking nut 3 is avoided. After the locking nut 3 is locked, the blocking assembly 5 is tightly pressed on the locking nut 3 through the anti-loosening component 4, so that the locking nut 3 and the anti-loosening component 4 realize rotation limitation, and reliable locking is realized. Further preferably, the ferrule is a tubular sleeve or nut structure. The tubular sleeve is convenient to install and low in cost. The nut structure can be directly additionally provided with a nut which is the same as the locking nut 3, and the operation is convenient.
Alternatively, the barrier assembly 5 comprises: a compression spring; the compression spring is sleeved on the body 1, one end of the compression spring is arranged on the locking nut 3 in a propping mode, and the other end of the compression spring is arranged on the end member II 4-2 in a propping mode, so that the locking nut 3 and the anti-loosening member 4 are kept in a pressing state all the time and are not easy to loosen.
The threaded holes 1-1 of the screw rods 4-1 are matched and connected through threads; the screw rod 4-1 and the end component II 4-2 are transited through a conical surface; an annular bulge 4-11 is arranged on the conical surface between the screw rod 4-1 and the end member II 4-2; after the screw rod 4-1 enters the threaded hole 1-1 to a preset position, the annular bulge 4-11 can be embedded into the annular groove 1-3; the diameter of the inner edge of the annular groove 1-3 is smaller than that of the outer edge of the annular bulge 4-11, so that after the annular bulge 4-11 is embedded into the annular groove 1-3, the two fan ring body structures 1-4 are expanded outwards to generate a proper amount of elastic deformation, and the locking nut 3 is prevented from loosening.
Preferably, the axial length of the fan-shaped ring body structure 1-4 is smaller than the depth of the threaded hole 1-1, so that the connection between the inside of the threaded hole 1-1 and the anti-loosening member 4 is reliable.
Preferably, the difference between the outer diameter of the body 1 and the inner diameter of the threaded hole 1-1 is 1/2-1/5 of the outer diameter of the body 1, so as to ensure the reliability of the body 1 and make the fan ring body structure 1-4 easily generate proper elastic deformation. Further preferably, the difference between the diameter of the inner edge of the annular groove 1-3 and the diameter of the outer edge of the annular protrusion 4-11 is 1/50-1/10 of the diameter of the taper hole structure 1-2 at the position of the annular protrusion 4-11, so that the elastic deformation of the fan-shaped ring body structure 1-4 is small, and the reliability of the body 1 is not affected.
Preferably, the taper of the taper between the screw rod 4-1 and the end member two 4-2 is larger than the taper of the taper hole structure 1-2 of the threaded hole 1-1, so that when the annular protrusion 4-11 is embedded into the annular groove 1-3 after the anti-loosening member 4 is connected with the body 1, the taper between the screw rod 4-1 and the end member two 4-2 can also be contacted with the taper hole structure 1-2, so as to increase the friction area and further reduce the possibility of loosening.
