Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of nut, especially lock nut's technical field.
[ background of the invention ]
The working principle of the nut is that the nut and the bolt are self-locked by friction force. But the reliability of such self-locking is reduced in dynamic loads. In some important occasions, some anti-loosening measures can be taken to ensure the locking reliability of the nut. One of the anti-loosening measures is a lock nut.
The existing lock nut is generally provided with a through threaded hole drilled from the outer circle surface to the inner circle thread surface of the nut for screwing in a small-diameter countersunk head screw, and aims to apply a force in a centripetal direction to the thread to prevent the lock nut from loosening. The existing locking nut is inconvenient to mount and dismount, and particularly, a great deal of time and energy are consumed when the locking nut is mounted in a narrow space.
[ Utility model ] content
The utility model discloses an aim at solving the problem among the prior art, provide a lock nut, can play fine locking effect, and the installation is all very convenient with the dismantlement.
For realizing the above-mentioned purpose, the utility model provides a lock nut, the nut comprises a nut body, be equipped with the screw thread through-hole on the nut body, the inboard of nut body is equipped with two fan-shaped grooves, be equipped with locking spring piece in the fan-shaped groove, locking spring piece includes middle chucking head, the both sides of chucking head are equipped with the hem, the outside of chucking head is connected with the support column, be equipped with the kelly on the support column, the nut body is equipped with the fluting with the corresponding side in fan-shaped groove, the fluting is linked together through hole and fan-shaped groove, the support column activity sets up in the through hole, grooved one side intercommunication has spacing draw-in groove.
Preferably, the clamping head is arc-shaped, the supporting column is provided with a spherical supporting head, and the supporting head is matched with the clamping head for installation.
Preferably, the tail end of the supporting column is provided with a four-corner groove for rotation.
Preferably, the clamping rod is positioned on one side of the supporting column close to the tail part.
The utility model has the advantages that: the locking spring piece is arranged on the inner side of the nut body, when the bolt and the nut are installed in a threaded mode, the screw can extrude the clamping head into the fan-shaped groove, and normal installation is not affected; after the installation, the chucking head of locking spring piece can correspond the ring channel that sets up on the chucking bolt, and the head of support column supports the chucking head, and the kelly butt of afterbody prevents that the chucking head from being extrudeed in the fan-shaped groove, plays fine locking effect on the spacing draw-in groove.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
[ description of the drawings ]
Fig. 1 is a schematic view of the locking state of the present invention;
fig. 2 is a schematic view of the installation state of the present invention;
fig. 3 is a schematic diagram of the slotting of the present invention;
fig. 4 is a schematic view of the lock spring plate of the present invention.
In the figure: the nut comprises a nut body 1, a threaded through hole 2, a sector groove 3, a locking spring piece 4, a support column 5, a slotted groove 6, a clamping head 41, a folded edge 42, a clamping rod 51, a spherical support head 52, a rectangular groove 53, a through hole 61 and a limiting clamping groove 62.
[ detailed description ] A
Referring to fig. 1, 2, 3 and 4, the utility model relates to a lock nut, including nut body 1, be equipped with screw thread through-hole 2 on the nut body 1, the inboard of nut body 1 is equipped with two fan-shaped grooves 3, be equipped with locking spring leaf 4 in the fan-shaped groove 3, locking spring leaf 4 includes middle chucking head 41, the both sides of chucking head 41 are equipped with hem 42, the outside of chucking head 41 is connected with support column 5, be equipped with kelly 51 on the support column 5, nut body 1 is equipped with fluting 6 with the corresponding side in fan-shaped groove 3, fluting 6 is linked together through hole 61 and fan-shaped groove 3, the activity of support column 5 sets up in through hole 61, one side intercommunication of fluting 6 has spacing draw-in groove 62, chucking head 41 is the arc, be equipped with spherical support head 52 on the support column 5, support head 52 with the installation is matchd to chucking head 41, the tail end of support column 5 is equipped with and is used for pivoted four corners groove 53, kelly 51 is located one side that support column 5 is close to the afterbody, spacing draw-in groove 62 is fan-shaped, two symmetry settings of 3.
When the locking nut is used, the nut is firstly installed on the bolt, when the installation is finished, the clamping heads on two sides can be clamped into the annular groove on the bolt, then the supporting column is rotated through a tool, the clamping rod is rotated into the limiting clamping groove, the nut is in a locking state, and the installation is finished; when needing to dismantle, rotate the support column through the instrument, make the kelly change over to fluting department, remove the locking state of nut, then with the nut dismantlement can.
