Specific embodiment
Further description is made to a specific embodiment of the invention below in conjunction with attached drawing 1-11.
Embodiment one, the technical solution solved is, including bolt 1, nut 2, which is characterized in that further include swivel nut 3, spiral shell
Line lid 4, internal pressure device 5；
The nut 2 is screwed on bolt 1, and swivel nut 3 has been screwed on the screw rod of 2 upper end of nut, the appearance of part on swivel nut 3
Face is equipped with external screw thread, and threaded cap 4 is screwed on the external screw thread of 3 upper end of swivel nut, in the swivel nut 3 between threaded cap 4 and screw rod
It is placed with internal pressure device 5, the internal pressure device 5 applies upward power after threaded cap 4 is tightened to threaded cap 4, right
Bolt 1 applies downward power.The embodiment when in use, will first be covered on screw, the screw above fastener by fastener
On screw nut 2, screw swivel nut 3 on the screw above nut 2, screw upper end be located in swivel nut 3 place internal pressure dress
5 are set, threaded cap 4 is screwed at the external screw thread on 3 top of swivel nut, tightens threaded cap 4, internal pressure device 5 is in own resilient
Apply downward power under effect to screw, applies upward power, screw connection point, the swivel nut 3 of screw and swivel nut 3 to thread cap
Screw connection point with threaded cap 4 is because the pressure stress that internal pressure device 5 applies increases to be held in position.
Compared to conventional nut, since conventional nut can be led when positioning elastic part (e.g. strain clamp drainage plate)
Cause elastic component deformation, unscrew and will lead to loose phenomenon, best torque can not be provided, or can not according to unified torque standard into
Row, because if will lead to elastic component deformation if unified torque standard is excessive.The pressure fastener device that the invention provides
It is to loosen to conventional nut, prevents conventional nut from retracting, when turning thread cap is transmitted the force to by spring
On the bolt and nut of lower part, the elastic component for needing to fasten at this time not by this pressure, therefore the invention use when can so that
Elastic fastener is unlikely to deform, and it can be made to fix fastening and be not easy to loosen, and since torque can be set as needed, because
This can make standard torque, be fastened according to standard to swivel nut by torque spanner.
Embodiment two, on the basis of example 1, the internal pressure device 5 are elastomeric element.The embodiment makes
Used time, swivel nut 3 is interior and side applies all objects of certain force up and down including that can be placed on for internal pressure device 5.

Used time, internal pressure device 5 can be located in the first spring 6 in swivel nut 3, and the size of spring force is according to circumstances selected
It selects.
Example IV, on the basis of embodiment three, 6 both ends of the first spring are equipped with upper stop piece 8 and lower stop piece 9.It should
Embodiment when in use, when internal pressure apparatus 5 is spring, is provided with baffle, baffle in the upper surface of spring and lower end surface
Touching screw upper end and emitting inner surface with screw thread makes to be more uniformly stressed.
Embodiment five, on the basis of example IV, upper stop piece 8 extends downwardly the guide rod being placed in the first spring 6
10, lower lever is extended with the guide sleeve 11 being slidingly fitted with guide rod 10 upwards.The embodiment when in use, in spring upper end
8 spring of upper stop piece in part extended downwardly guide rod 10, the part in 9 spring of lower stop piece of lower spring end is stretched upwards
There is guide sleeve 11 out, be slidably matched between guide sleeve 11 and guide rod 10, play the guiding role during spring-compressed, prevent bullet
Spring friction 3 inner wall of swivel nut.
Embodiment six, on the basis of example 1, the internal pressure device 5 is by upper air pressure set 12 and lower air pressure set 13
And constituted in upper air pressure set 12 and lower air pressure set 13, cooperation is slidingly sealed between upper air pressure set 12 and lower air pressure set 13.The reality
Example is applied when in use, during tightening thread cap, due to being slidingly sealed cooperation, upper air pressure set 12 between upper and lower air pressure set 13
Air between lower air pressure set 13 is compressed, and rear air pressure is twisted and pushes 13 separation of upper and lower air pressure set, under the action of atmospheric pressure
It is downwardly applied to power upwards, keeps the screw connection point, swivel nut 3 and the screw connection point of threaded cap 4 of screw and swivel nut 3 equal because in
The pressure stress that portion's pressure apparatus 5 applies increases to be held in position.
