Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of stop nut with double locking mechanism provided in the present embodiment, including installation
Screw rod 4, the stop nut with double locking mechanism further includes the first lock nut 1, the second lock nut 2 and ball 3；The
One lock nut 1, the second lock nut 2 are socketed on installation screw rod 4, and are threadedly coupled with it, the one of the second lock nut 2
End cap is connected to the outside of the first lock nut 1, and the end face of the first lock nut 1 is abutted with the end face of the second lock nut 2；Ball
3 are located in the side wall of the first lock nut 1, and 3 side of ball is abutted with installation screw rod 4, the other side of ball 3 and the second locking
The inner sidewall of nut 2 abuts.3 material of ball uses copper material；During installation, when nut is twisted from top to bottom, spiral shell is locked by first
A part of mother 1 is screwed on installation screw rod 4, will then by ball 3 from the receiving hole 12 that 1 inner wall of the first lock nut is put into
First lock nut 1 is screwed on installation screw rod 4, and ball 3 protrudes from the lateral wall of the first lock nut 1 at this time, and will not drop out；
When nut is twisted from the bottom up, a pole first can be placed inside the first lock nut 1, ball 3 is then locked into spiral shell from first
In the receiving hole 12 that female 1 inner wall is put into, then the first lock nut 1 will be screwed into again on installation screw rod 4, and utilize installation screw rod 4
Pole is squeezed out, so that ball 3 is not fallen out during installation；And there is no extruding force between ball 3 and installation screw rod 4 at this time.So
The second lock nut 2 is screwed into installation screw rod 4 again afterwards, the clamping set 22 of the second lock nut 2 is located at the first lock nut 1
The conical grooves 231 in outside, and being screwed into the second lock nut 2, clamping set 22 are contacted with ball 3, and due to conical grooves 231
It is more smaller toward 2 middle position of the second lock nut, so that extruding force when the second lock nut 2 is screwed into ball 3 is gradually increased.
When the second lock nut 2 is abutted with the first lock nut 1, reach final locking state, reach the state needs torque by
The gradient of conical grooves 231 is determined with depth is screwed into.Installation screw rod 4 is squeezed eventually by ball 3, ball 3 is allowed to limit the
One lock nut 1 loosens, while 3 the second lock nut of oblique compression 2 of ball, so that the second lock nut 2 and installation spiral shell
Frictional force increases between bar 4, so that the second lock nut 2 firmly installs, then passes through the first lock nut 1 and the second lock nut
2 fit closely, and can also play mutual restrictive function each other, so that locking is stronger.
As shown in Fig. 4, Fig. 5, Fig. 6, the side wall of the first lock nut 1 is provided with receiving hole 12, and receiving hole 12 is close to first
One end of 1 lateral wall of lock nut is sphere hole 121, and sphere hole 121 is bonded with ball 3, and a part of ball 3 stretches out first
The lateral wall of lock nut 1.When the second lock nut 2 is not screwed into, the diameter of ball 3 is just equal to the straight of receiving hole 12
Diameter, ball 3 can be put into receiving hole 12 from inner sidewall, and by the setting of sphere hole 121 so that ball 3 will not drop out the
The lateral wall of one lock nut 1, so that easy for installation.
As shown in Figure 2 and Figure 3, one end of the second lock nut 2 is provided with clamping set 22, is provided with limit in clamping set 22
One end of slot 23, the first lock nut 1 is located in limiting slot 23.Pass through making so that the second lock nut 2 exists for limiting slot 23
After abutting with the first lock nut 1, the second lock nut 2 cannot be screwed into again, can avoid 2 mistake of the second lock nut well
Degree squeezes ball 3, avoids ball 3 and installation screw rod 4 damages.
As shown in Figure 2 and Figure 3, conical grooves 231 are configured on the outside of limiting slot 23, and conical grooves 231 are close to the second lock nut
It is osculum at 2 medium positions, the medial surface of conical grooves 231 is abutted with ball 3.It is arranged by conical grooves 231, so that the second locking
Nut 2 can be more easily screwed into, gradually increase the extruding force to ball 3 during being screwed into, while conical grooves 231 are set
It sets, so that the opposition that ball 3 gives the second lock nut 2 is also slanting, the existing axial direction of such second lock nut 2
Power has lateral force again, so that the frictional force between the second lock nut 2 and installation screw rod 4 is bigger, installs stronger.
Preferably, the other end of the second lock nut 2 is provided with installation base 21, and the inner sidewall of installation base 21 is provided with
The end face that screw thread, installation base 21 and limiting slot 23 connect is bearing surface, the abutting of the first lock nut 1 and installation base 21
Face abuts against.Further, the lateral wall of installation base 21 is configured to hexagon.It is set by the inner sidewall screw thread of installation base 21
Meter can cooperate with installation screw rod 4 well, while 21 lateral surface of installation base is set as hexagon, can be more convenient second
Lock nut 2 is screwed into.
Preferably, the lateral wall of the first lock nut 1 is provided with several non-slip grooves 11, and the first lock nut 1 opens up
There is the lateral wall of receiving hole 12 to be not provided with non-slip groove 11.Since 1 lateral surface of the first lock nut is provided in round, so that it is screwed into
When it is not convenient enough, therefore be provided with non-slip groove 11, the friction of 1 outer surface of the first lock nut can be increased by non-slip groove 11
Power allows the first lock nut 1 to twist tighter.
The utility model is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from this reality
In the case where with novel spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.This reality
It is not limited to the particular embodiment disclosed with novel, other embodiments fallen into claims hereof all belong to
In the range of the utility model protection.
