Abstract
Fast disassembly type without screw lever fixing apparatus, including:Sub- blind nut and female blind nut, the female blind nut and screw rod are integral type, and outside is equipped with pressing hole, and is internally hollow and has following symmetry strip gab, and the symmetry strip gab bottom does not open up.The sub- blind nut is built-in with safety elastic cramp, the safety elastic cramp is made of fore-set and compression spring, after screw rod is inserted in the hole in place, twist half circle blind nut, elastic fastening plate can be ejected from screw rod opening, play fixation, when not in use, shrapnel is depressed with hand purport, shrapnel is withdrawn reversion half-turn in screw rod by rear rock blind nut can extract screw rod out.Without screw lever fixing apparatus, when replacement, need not have fast disassembly type provided by the invention by assistant engineer, and one to insert be that one pulls out to go out, and effectively solves the problems, such as time-consuming and laborious.
Description
Technical field
The invention belongs to field of fixation devices, and in particular to a kind of fast disassembly type is without screw lever fixing apparatus.
Background technology
At present, the screw device of in the market, mostly there is the fixed form of screw rod structure, replace when generally require by
Instrument, it is difficult to be screwed out when replacing, and dismounting needs instrument time-consuming and laborious, a kind of fast disassembly type of offer regarding to the issue above without
Screw lever fixing apparatus.
The content of the invention
The present invention is a kind of without silk quick connection structure to provide, and one to insert be that one pulls out to go out, and without instrument, time saving and energy saving is fast
Formula is torn open without screw lever fixing apparatus.
To solve the above problems, the technical solution adopted by the present invention is：Fast disassembly type without screw lever fixing apparatus, including:Son
Blind nut and female blind nut, the female blind nut and screw rod are integral type, and outside is equipped with pressing hole, and is internally hollow and has following
Symmetry strip gab, the symmetry strip gab bottom do not open up.The sub- blind nut is built-in with safety elastic button
Piece, the safety elastic cramp is made of fore-set and compression spring, after screw rod is inserted in the hole in place, twists half circle blind nut,
Elastic fastening plate can be ejected from screw rod opening, play fixation, when not in use, shrapnel, rear rock blind nut be depressed with hand purport
Shrapnel, which is withdrawn reversion half-turn in screw rod, can extract screw rod out.
Preferably, pressing hole is left on the outside of new screw of the present invention.
Preferably, symmetry strip gab shape of the present invention is 0 shape mouth.
Without screw lever fixing apparatus, when replacement, need not have fast disassembly type provided by the invention by assistant engineer, and one to insert be that one pulls out i.e.
Go out, effectively solve the problems, such as time-consuming and laborious.
Brief description of the drawings
Fig. 1 is the front view of the present invention
Fig. 2 is the sub- blind nut top view of the present invention.
Embodiment
Fast disassembly type as shown in Figure 1 and Figure 2 without screw lever fixing apparatus, including:Sub- blind nut 3 and female blind nut 7, the mother
Blind nut 7 and screw rod 5 are integral type, and outside is equipped with pressing hole 6, and is internally hollow and has following symmetry strip gab, institute
The symmetry strip gab bottom stated does not open up.The sub- blind nut is built-in with safety elastic cramp 11, the safe bullet
Property cramp 11 be made of fore-set 1 and compression spring 2, after screw rod 5 is inserted in the hole 12 in place, twist half circle blind nut 3, elastic fastening plate
It can be ejected from screw rod opening, play fixation, when not in use, depress shrapnel 11 with hand purport, rear rock blind nut is shrapnel
Screw rod 5 can be extracted out by withdrawing 5 reversion half-turns in screw rod.
