The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Example one
Referring to fig. 1 to 3, the embodiment discloses a false locking prevention bolt, which includes a bolt head 1, a polished rod 2 and a screw rod 3, wherein the bottom surface of the bolt head 1 is sequentially and integrally connected with the polished rod 2 and the screw rod 3 to form a bolt, and the outer diameter of the polished rod 2 is smaller than the small diameter of the external thread of the screw rod 3;
be equipped with in the bolt and run through bolt head 1 and polished rod 2 and enter into the inside oil feed passageway 4 of screw rod 3, oil feed passageway 4 one end sets up at bolt head 1 top surface, and the other end sets up in screw rod 3, screw rod 3 is equipped with oil outlet 31, oil outlet 31 one end and the intercommunication of oil feed passageway 4, the other end setting is in 3 outer wall sides of screw rod.
As shown in fig. 1, the part 5 is fixed on the fixing member 6 by using the bolt, when the thickness of the part 5 is greater than the polish rod 3, the screw rod 3 passes through the through hole on the part 5 to enter the internal thread hole on the fixing member 6 and is in threaded fit with the internal thread hole, because the outer diameter of the polish rod 2 is smaller than the small diameter of the external thread of the screw rod 3, namely, the outer diameter of the polish rod 2 is smaller than the small diameter of the internal thread hole, the part of the polish rod 2 longer than the thickness of the part 5 can extend into the internal thread hole of the fixing member 6, and then the part 5 is effectively compressed and fixed on the fixing member 6 by using the bolt head 1, thereby preventing the false locking.
In addition, because the bolt is locked and fixed for a long time, the surface of the bolt is easy to rust, the bolt cannot be normally disassembled, and the bolt is easy to damage; the event is in be equipped with in the bolt and run through bolt head 1 and polished rod 2 and enter into 3 inside oil feed passageway 4 of screw rod and one end and oil feed passageway 4 intercommunication, the other end sets up the oil outlet 31 in 3 outer wall sides of screw rod, when the bolt surface rusts unable dismantlement, inject lubricating oil in the top surface oil feed passageway 4 of bolt head 1, lubricating oil flows into oil outlet 31 and enters into the internal thread hole of mounting 6 from oil feed passageway 4, play the lubrication action to 3 external screw threads of screw rod and the internal thread hole of mounting 6, can dismantle the bolt fast, and is not fragile bolt.
Furthermore, the end part of the polish rod 2 is in transition connection with the bolt head 1 and the screw rod 3 through fillets, so that stress rupture caused by stress concentration at two ends of the polish rod 2 can be effectively prevented.
The working principle of the embodiment is as follows: when the thickness of the part 5 is larger than that of the polish rod 3, the screw rod 3 penetrates through the through hole in the part 5 to enter the internal thread hole in the fixing part 6 and is in thread fit with the internal thread hole, because the outer diameter of the polish rod 2 is smaller than the small diameter of the external thread of the screw rod 3, namely, the outer diameter of the polish rod 2 is smaller than the small diameter of the internal thread hole, the part of the polish rod 2, which is longer than the thickness of the part 5, can extend into the internal thread hole of the fixing part 6, then the part 5 is effectively compressed and fixed on the fixing part 6 through the bolt head 1, the false locking phenomenon of the bolt is prevented, the aim of effectively locking the part is achieved, and the end part of the polish rod 2 is respectively in transition connection with the bolt head 1 and the screw rod 3.
In addition, when the bolt surface rusts and can not be disassembled, lubricating oil is injected into the top surface oil inlet channel 4 of the bolt head 1, the lubricating oil flows into the oil outlet hole 31 from the oil inlet channel 4 and enters the internal thread hole of the fixing part 6, the lubricating effect on the external thread of the screw rod 3 and the internal thread hole of the fixing part 6 is achieved, the bolt can be disassembled quickly, and the bolt is not easy to damage.
Example two
Referring to fig. 4 and 5, in the present embodiment, on the basis of the first embodiment, a groove 11 communicated with the oil inlet channel 4 is further disposed on the top surface of the bolt head 1, and a dust cover 7 is disposed in the groove 11.
The groove 11 is in a regular hexagonal shape, the dust cover 7 is in a regular hexagonal shape capable of being matched with the groove 11, and the top surface of the dust cover 7 is also provided with a drawing head 71 used for taking out the dust cover 7.
Specifically, after the bolt is fixed, the dust cap 7 is covered in the groove 11, so that dust is prevented from entering the oil inlet channel 4 to block the oil inlet channel, and the later-stage lubricating oil is inconvenient to be injected, and when the bolt is disassembled at the later stage, the dust cap 7 is taken out through the drawing head 71, the lubricating oil is injected into the oil inlet channel 4, and then the bolt is disassembled; when the outer surface of the bolt head 1 is worn and cannot be disassembled, the bolt can be disassembled by replacing the hexagon socket wrench which can be matched with the groove 11 in the shape of the regular hexagon.
EXAMPLE III
Referring to fig. 6 and 7, the difference between the present embodiment and the second embodiment is that the groove 11 is an internal thread groove, and the dust cap 7 is provided with an external thread matching with the internal thread of the groove 11.
The top surface of the dust cover 7 is provided with a square groove 72 for rotating the dust cover 7, so that the dust cover can be conveniently disassembled and assembled.
The direction of rotation of the internal thread of the groove 11 is opposite to the direction of rotation of the external thread of the screw 3.
Specifically, after the bolt is fixed, the dust cap 7 is covered in the groove 11, the dust cap 7 is rotated by inserting the screw driver into the square groove 72 and is connected with the groove 11 in a matched manner, so that dust is prevented from entering the oil inlet channel 4 to block the oil inlet channel, and later-stage lubricating oil is inconvenient to inject, and when the bolt is disassembled later, the dust cap 7 is taken out by rotating the dust cap 7 by inserting the screw driver into the square groove 72, then lubricating oil is injected into the oil inlet channel 4, and then the bolt is disassembled; when the outer surface of bolt head 1 wears and can't dismantle the bolt, can insert one in recess 11 with recess 11 internal thread fit's bolt, through rotating the bolt for the bolt locking is in recess 11 of bolt head 1, then continues to rotate the male bolt, because the internal thread direction of rotation of recess 11 is opposite with the direction of rotation of 3 external threads of screw rod, can make the male bolt drive the bolt rotation of being connected with mounting 6, thereby realizes the dismantlement to the bolt.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
