Description
Technical field
This practical technical field for being related to screw and locking, the in particular to switch of a kind of nut with quick locking screw
Back box
Background technique
At present lock screw be by screw and nut relative rotary motion to lock, be commonly used in switch on wall or
The lock-screw of socket is longer, and when locking is often required to have rotated one section of length, screw just can whole precessions go, it is time-consuming and laborious.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of screw nut switch bottom with quick locking screw
Box, it is time-consuming and laborious when solving the problems, such as long spiro nail locking in the prior art.
A kind of screw nut switch back box with quick locking screw, nut are made of the outline border of Jiong shape and the inside casing of Jiong shape,
The outline border and inside casing are integrally formed, and the midpoint of the inside casing is two ends of inside casing, two end be equipped with downwards and
Pars convoluta backwards, the centre of two pars convoluta are respectively equipped with semicircle orifice, on the outline border is corresponding with the circular hole that two halves circular hole forms
Equipped with screw perforation.
Further, the diameter of the screw perforation is 2mm-5mm bigger than the diameter of circular hole.
Further, the outline border and inside casing are made of steel disc or copper sheet integrated molding.
Further, the nut for being used for quick locking screw is set to switch bottom case: the switch bottom case is equipped with spiral shell
Female fixed frame, the top surface of the nut fixed frame is equipped with the second screw perforation corresponding with nut perforation, described to be used for quick locking
The nut of screw fills in nut fixed frame by interference fit, and the screw perforation is aligned with the second screw perforation.
The utility model has the beneficial effects that
It is practical by this, when carrying out locking straight angle screw, screw is passed through into perforation, pushes up to the both ends of inside casing, at this moment uses
Power presses screw down, and screw supports at the both ends of inside casing down, it is distracted in a flash, spiral shell ratio firmly by pressure rapidly down
Reach it is low, it is time saving and energy saving as long as carrying out being locked screw with screw knife here.

Specific embodiment
As shown in Figures 1 to 5, a kind of nut for quick locking screw, by the outline border 10 of Jiong shape and the inside casing of Jiong shape
20 compositions, the outline border 10 and inside casing 20 are integrally formed, and the midpoint of the inside casing 20 is two ends of inside casing, two end
It is equipped with downwards and pars convoluta 21 backwards, the centre of two pars convoluta 21 is respectively equipped with semicircle orifice 22, the outline border 10 and two halves
The circular hole of circular hole composition is corresponding to be equipped with screw perforation 11.
In embodiment, the diameter of the screw perforation is 2mm-5mm bigger than the diameter of circular hole, the outline border 10 and inside casing
20 are made of the flexible metal material integrated molding such as steel disc or copper sheet.
The quick locking of this practical straight angle screw 30 bigger than circular hole suitable for screw diameter, straight angle screw 30 is screw rod
It is columnar screw, when carrying out screw locking, screw is passed through into screw perforation 11, pushes up to the both ends of inside casing 20, at this moment uses
Power strikes screw down, and in firmly pressing, in a flash, straight angle screw 30 struts at the both ends of inside casing 20 down makes two and half
The separation of circular hole 22 is extremely also bigger than the diameter of the screw rod of screw, at this point, inside casing 20 is in M shape, screw is firmly rapid down by pressure
It reaches down to head of screw close to outline border, at this point, inside casing 20 restores original switch under the action of elastic force, two semicircle orifices just block
Screw rod has been lived, it is time saving and energy saving as long as carrying out being locked screw with screw knife here.
As shown in fig. 6, the nut 50 for being used for quick locking screw is set to switch bottom case 40: the switch bottom case 40
Equipped with nut fixed frame 41, the top surface of the nut fixed frame 41 is equipped with the second screw perforation 42 corresponding with nut perforation, described
Nut for quick locking screw fills in nut fixed frame 41 by interference fit, and the screw perforation 11 is worn with the second screw
Hole 42 is aligned.
When carrying out locking switch box cover, screw is passed through to through-hole, the perforation of box cover, top to the both ends of inside casing, firmly
Pressing in a flash, screw the both ends of inside casing are strutted down make two semicircle orifices separate to the screw rod than screw diameter also
Greatly, screw is firmly being reached down to head of screw close to switch enclosure cover rapidly by pressure down, will with screw knife as long as carrying out here
Screw locking, it is time saving and energy saving.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above, it is right
For those skilled in the art, it is clear that the present invention is not limited to the details of the above exemplary embodiments, and without departing substantially from
