Abstract
The utility model relates to an anti-loose fastener comprising a nut body and a screw rod which are screwed with each other, wherein one end of the screw rod is provided with outer threads, while the other end of the screw rod is provided with a plug; the nut body is a regular polygon solid which is axially provided with an inner threaded through hole; the central zones of at least two opposite side surfaces in the nut body are respectively provided with an axial strip-shaped hole which is communicated the inner threaded through hole; the axial center lines of the two strip-shaped holes and the axis of the nut body are in the same plane; one end of the screw rod, provided with outer threads, is provided with a radial perforation through the axis; and a cotter pin is arranged in the strip-shaped hole at one side, the perforation and the other strip-shaped hole at the opposite side, so that the nut body is positioned on the screw rod. Two ends of the cotter pin, outside the nut body, are respectively sheathed with a gasket. The nut body is a regular polygon solid; the central zones of every two opposite side surfaces in the nut body are respectively provided with one axial strip-shaped hole which is communicated the inner threaded through hole; and the axial center lines of every two opposite strip-shaped holes and the axis of the nut body are positioned on the same plane. The anti-loose fastener does not loose due to shake in use.
Description
Technical field
The utility model relates to a kind of anti-loosening fastening piece.
Background technique
The existing fastening piece of being made up of screw bolt and nut is easy for installation, dismounting easily, use extensive.Because of employing is threaded, make nut loosening easily.At present, locking for described fastening piece, extensively adopt the simple structure of double nut or spring washer, though these structures have certain anti-loosing effect, but still have following deficiency: described fastening piece still can produce the phenomenon of nut loosening, so that its safety factor is lower when shaking acutely or use in the place that takes regular exercise, be prone to accidents, jeopardize and produce and personal safety.
The model utility content
Technical problem to be solved in the utility model provides a kind of anti-loosening fastening piece, and this anti-loosening fastening piece can not cause loosening because of reasons such as vibrations in use.
For solving the problems of the technologies described above, the utility model provides a kind of anti-loosening fastening piece, it comprises cap body and the screw rod that spins mutually, screw rod one end is provided with outside thread, the other end is provided with plug, the cap body is for axially having just many ribs block of internal thread through hole, the center region of at least two opposite flanks has an axial bar hole that communicates with internal thread through hole separately in the described cap body, and the longitudinal center line of two bar holes, the common plane of the axis of cap body, screw rod is provided with the radial perforation that an externally threaded end had axis, cotter pin is placed in the bar hole of a side, perforation, relatively in the bar hole of opposite side, so that the cap body obtains the location on screw rod.
For the purpose of the brief description problem, below the anti-loosening fastening piece of the utility model is all abbreviated as this fastening piece.
After adopting above structure, by being placed in the cotter pin in a side bar hole, perforation, the relative opposite side bar hole, make the cap body on screw rod, obtain the location, the relative position of cap body and screw rod is fixed, like this, even this fastening piece is when shaking acutely or use in the place that takes regular exercise, because the positioning action of cotter pin, the cap body can be at the screw rod top offset, thereby can not produce the loosening phenomenon of cap body, so that the safety factor of this fastening piece is higher, effectively avoids having an accident, and has improved and has produced and personal safety.
In sum, this fastening piece can not cause loosening because of reasons such as vibrations in use.
In addition, that this fastening piece also has is easy to use, easy processing, be fit to the advantage of large-scale production.
As optimization of the present utility model, cotter pin is in each suit one pad of the external two ends of cap.
The setting of two pads makes that cotter pin is difficult for passing and slippage from the bar hole of a side bar hole, perforation, relative opposite side, further improve the anti-loosening performance of this fastening piece.
As optimization of the present utility model, the cap body is positive six rib blocks, the center region of per two opposite flanks all has an axial bar hole that communicates with internal thread through hole separately in the cap body, and all common plane of axis of the longitudinal center line of relative per two bar holes, cap body.
Like this, utilize in perforation on the screw rod and the cap body bar hole on the two opposite side surfaces arbitrarily, can relatively easily settle cotter pin.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a stereogram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing mode of execution of the present utility model is specifically described:
Referring to Fig. 1, Fig. 2, this fastening piece comprises cap body 1 and the screw rod 2 that spins mutually, screw rod 2 one ends are provided with outside thread 21, the other end is provided with plug 22, cap body 1 is for axially having the positive six rib blocks of internal thread through hole, the center region of per two opposite flanks all has an axial bar hole 11 that communicates with internal thread through hole separately in the cap body 1, and the longitudinal center line of relative per two bar holes 11, the all common plane of the axis of cap body 1, the end that screw rod 2 is provided with outside thread 21 had the radial perforation 23 of axis, cotter pin 3 is placed in the bar hole 11 of a side, perforation 23, relatively in the bar hole 11 of opposite side, so that cap body 1 obtains the location on screw rod 2.Cotter pin 3 is in each suit one pad 4 of two ends outside the cap body 1.
Above-described only is a kind of mode of execution of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
