The present invention proposes a kind of Anti-loose fastener assembly, including bolt and coordinate with bolt workpiece is carried out spacing nut, the described nut coordinated with bolt opposite piece homonymy is at least two, including with the lower nut of absorption surface and the top nut spacing to lower nut, it is provided with one between said two nut and lower nut is carried out spacing positioning cap button, and positioning cap retaining ring is located on lower nut, described positioning cap button includes the cap of and corresponding nut coupling, and connected on cap buckles for clasping the curved of workpiece edge.The cap of positioning cap button is enclosed within the lower nut mated with its size, the galianconism of curved button clasps the edge placement of corresponding workpiece, it is positioned such that such as same back-up wrench buckled by cap, the pine limiting lower nut moves back, re-use screw time necessary to be fixed on workpiece through spacing hole, the lower nut fastened is carried out the most spacing, effectively prevents from loosening.
Description
Technical field
The present invention relates to bolt fixture field, particularly relate to a kind of Anti-loose fastener assembly.
Background technology
Thread connection is the removable connection utilizing thread part to constitute, and its simple in construction is convenient to mount and dismount, extensively
It is applied in various plant equipment.But under shock and vibration or varying load effect, or become at high temperature or temperature
Change relatively big in the case of, pretightning force in thread connection and frictional force can be gradually reduced or may momentary loss,
Cause coupling and lost efficacy.Thread connection once lost efficacy, and will have a strong impact on the normal work of machine, and even cause thing
Therefore.Therefore, in the design production process of engineering goods, often use nut check mechanism to ensure connection
Connect safe and reliable.Modal nut check mechanism is two, axle nut, by two spanner counter-rotatings,
Make two nuts mutually extrude, it is achieved the locking of strength, prevent couple to get loose.
But the mode of pairs of anti-loose nut not absolute stability, when shock and vibration load effect, nut with
Frictional force between workpiece may reduce and even disappears, the particularly vibration environment of some altofrequency high-amplitude
In, use the anti-loose structure of double nut still can get loose.So needing the one can be the most effective
Prevent the fastening assembly come off.
Summary of the invention
The present invention proposes a kind of Anti-loose fastener assembly, it is possible to when shock and vibration load effect to nut
Carry out spacing, effectively prevent nut loosening from coming off.
The technical scheme is that and be achieved in that: a kind of Anti-loose fastener assembly, including bolt and
Coordinate with bolt carries out spacing nut to workpiece, and the described nut that coordinates with bolt opposite piece homonymy is
At least two, including with the lower nut of absorption surface and the top nut spacing to lower nut, said two nut
Between be provided with one lower nut carried out spacing positioning cap button, and positioning cap retaining ring is located on lower nut, institute
State positioning cap button and include the cap of and corresponding nut coupling, and connected on cap is used for clasping
The curved of workpiece edge is buckled.
As preferably, described cap is that open at one end one end is closed, and uncovered interior shape is with limited
Lower nut shape size mates, and cap is closed the middle part of one end and had the through hole allowing corresponding bolt pass through.
As preferably, the vertical section of described curved button is L-shaped, including integrated long-armed and galianconism, its
On the sidewall of long-armed uncovered one end of connection cap, and the direction phase of the most long-armed overbending direction of galianconism and cap
Instead.
As preferably, have one in the middle part of the galianconism of described curved button for being fixed on workpiece by positioning cap button
Spacing hole.
As preferably, being provided with damping means between described lower nut and workpiece, described damping means is rubber blanket
Circle or spring washer.
As preferably, the curved latch portion thickness of described positioning cap button is not less than 3mm.
Compared with prior art, it is an advantage of the current invention that: the cap of positioning cap button is enclosed within and mates with its size
Lower nut on, the galianconism of curved button clasps the edge placement of corresponding workpiece, is positioned such that cap is buckled as same is solid
Determining spanner, the pine limiting lower nut moves back, and re-uses screw and be fixed on workpiece through spacing hole time necessary,
The lower nut fastened is carried out the most spacing, effectively prevents from loosening.Top nut again from top to fixed
Position cap is buckled and is fixed, and positioning cap button plays the effect being equivalent to a spring pad for top nut.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete
The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under work premise, broadly falls into the scope of protection of the invention.
Embodiment: seeing Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of Anti-loose fastener assembly, including bolt
6 and coordinate with bolt 6 workpiece 7 is carried out spacing nut, described with bolt 6 opposite piece 7 homonymy
The nut coordinated is at least two, including the lower nut 2 contacted with workpiece 7 with to spacing upper of lower nut 2
Nut 3, is provided with one and lower nut 2 carries out spacing positioning cap button 1, and location between said two nut
Cap is buckled 1 and is set on lower nut 2, and described positioning cap button 1 includes the cap 11 of and corresponding nut coupling,
And connected on cap 11 is for clasping curved button the at workpiece 7 edge.
As preferably, described cap 11 is closed for open at one end one end, and uncovered interior shape is with limited
