Abstract
The utility model relates to a looseness -prevention bolt, including pole portion, set up the head in pole portion one end, be equipped with the external screw thread in the pole portion, be equipped with a plurality of antiskid tooth on the medial surface of head, its characterized in that: the head upwards be equipped with plastics rings week, the medial surface of plastics rings on extend flexible piece, the flexure strip set up for the medial surface slope of plastics rings. The present invention uses the technical scheme, the utility model provides a looseness -prevention bolt, it externally shakes when great, has buffering effect well to reduce anti -skidding tooth and by the wearing and tearing between the fixture, prolong its life -span.
Description
Technical field
The utility model is related to fastener areas, more particularly to a kind of check bolt.
Background technology
Existing check bolt, includes bar portion, is arranged on the head of one end of the rod, and bar portion is provided with external screw thread, head
Medial surface be provided with several anti-slop serrations, so bolt installation after, the anti-slop serrations on head can well prevent head
Skidding is produced between fixation body, so as to play locking effect.But, the check bolt of this structure, in exterior vibration
When larger, wear and tear between anti-slop serrations and fixation big, be easily damaged anti-slop serrations, service life is short.
The content of the invention
The purpose of this utility model：In order to overcome the defect of prior art, the utility model to provide a kind of check bolt,
It, with buffering effect well, so as to reduce the abrasion between anti-slop serrations and fixation, extends when exterior vibration is larger
Its life-span.
The technical solution of the utility model：A kind of check bolt, includes bar portion, is arranged on the head of one end of the rod, bar
Portion is provided with external screw thread, and the medial surface of head is provided with several anti-slop serrations, it is characterised in that：Set in the circumference of described head
There is a plastic hoop, be extended with flexure strip on the medial surface of described plastic hoop, the medial surface of described flexure strip relative to plastic hoop
It is obliquely installed.
Using above-mentioned technical proposal, after bolt installation, when exterior vibration is larger, flexure strip can play certain
Cushioning effect, can reduce the abrasion between anti-slop serrations and fixation, extend its life-span；In addition, flexure strip can be produced when mounted
The certain crimp of life, so as to give bolt certain thrust so that the anti-loosing effect of bolt is more preferable.
Further setting of the present utility model：Described plastic hoop includes ring body, sets on the inner ring face of described ring body
There is annular boss, flexure strip is arranged on the medial surface of ring body, the circumference of described head is provided with annular groove, described ring
Shape boss is arranged in annular groove.
Using above-mentioned further setting, the plastic hoop set-up mode of this structure, its more stable, simple structure of positioning.
It is of the present utility model further to arrange：Annular boss is moulded in annular groove the company for forming plastic hoop and head
Connect.
Further arranged using above-mentioned, plastic hoop is integrated with the head injection of bolt, processes convenient, and connection is more
Plus it is firm.
It is of the present utility model further to arrange again：Described flexure strip includes connection sheet, substrate, connection sheet one end with
The medial surface connection of ring body, the other end is connected with substrate, and described connection sheet is obliquely installed relative to the medial surface of ring body, substrate
It is arranged in parallel with the medial surface of ring body.
Further arranged again using above-mentioned, the substrate of setting can cause contact surface between flexure strip and fixation
Greatly, buffering effect is more preferable, and, the elastic-restoring force for installing rear connecting piece generation is more stable, and anti-loosing effect is more preferable.
It is of the present utility model further to arrange again：The medial surface of described substrate is provided with some sawtooth, and described is anti-
The tapered setting of slip teeth, sawtooth.
Further arranged again using above-mentioned, can cause that skidding will not be produced between substrate and fixation；Separately
Outer this anti-slop serrations, sawtooth set-up mode, good antiskid effect.
Description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is bolt shank, head construction figure in the utility model specific embodiment；
Fig. 3 is plastic hoop, flexure strip structure chart in the utility model specific embodiment.
Specific embodiment
As Figure 1-3, a kind of check bolt, includes bar portion 1, is arranged on the head 2 of the one end of bar portion 1, sets in bar portion 1
The medial surface for having external screw thread 11, head 2 is provided with several anti-slop serrations 3, and the circumference of described head 2 is provided with plastic hoop 4, institute
Flexure strip 5 is extended with the medial surface of the plastic hoop 4 stated, described flexure strip 5 is inclined relative to the medial surface of plastic hoop 4 and set
Put.After bolt installation, when exterior vibration is larger, flexure strip 5 can play certain cushioning effect, can reduce anti-slop serrations
Abrasion between 3 and fixation, extends its life-span；In addition, flexure strip 5 can produce when mounted certain crimp, from
And can give bolt certain thrust so that the anti-loosing effect of bolt is more preferable.
In the utility model specific embodiment, described plastic hoop 4 includes ring body 41, the inner ring face of described ring body 41
Annular boss 42 is provided with, flexure strip 5 is arranged on the medial surface of ring body 41, the circumference of described head 2 is provided with annular recessed
Groove 21, annular boss 42 is moulded in annular groove 21 connection for forming plastic hoop 4 and head 2.The plastic hoop 4 of this structure sets
Mode is put, its more stable, simple structure of positioning；Plastic hoop 4 is integrated with the injection of head 2 of bolt, processes convenient, even
Connect more firm.
In the utility model specific embodiment, described flexure strip 5 includes connection sheet 51, substrate 52, connection sheet 51 1
End is connected with the medial surface of ring body 41, and the other end is connected with substrate 52, the medial surface of described connection sheet 51 relative to ring body 41
It is obliquely installed, substrate 52 be arranged in parallel with the medial surface of ring body 41.Can cause flexure strip 5 and be consolidated by the substrate 52 for arranging
Contact surface is big between earnest, and buffering effect is more preferable, and, the elastic-restoring force for installing the generation of rear connecting piece 51 is more stable, prevents
Loose effect is more preferable.
In the utility model specific embodiment, the medial surface of described substrate 52 is provided with some sawtooth 521, and described is anti-
The tapered setting of slip teeth 3, sawtooth 521.So can cause that skidding will not be produced between substrate 52 and fixation；Separately
Outer this anti-slop serrations 3, the set-up mode of sawtooth 521, good antiskid effect.
