Abstract
The utility model discloses a kind of stop nut, include metal nuts body (1), described metal nuts body (1) includes thread segment (2) and construction section (3), elastomer (4) is provided with described construction section (3), internal thread (5) is provided with shown elastomer (4), described internal thread (5) gradually increases from thread segment (2) starting pitch；Can preferably solve the problems, such as that existing bolts and nuts fasten loosening caused by being given a shock；Metal nuts coordinate with bolt can get rusty for a long time, cause difficult the problems such as dismantling unsightly, and can prevent that cylindrical one end of nut from entering water, dust etc. plus the stop nut of nylon elastomer, can effectively reduce the problem of being got rusty after nut coordinates with bolt.
Description
Technical field
It the utility model is related to a kind of stop nut.
Background technology
General bolt, nut are easy to weaken by its adhesion when external impact and vibration, can unclamp easily, or even bolt
Can be completely disengaged with nut, bury the potential safety hazards such as the impaired of structure, collapse, due to frequent vibration cause fastening loosen into
For one it is universal the problem of.
Utility model content
The purpose of this utility model is to provide a kind of stop nut structure solve existing bolts and nuts due to being shaken
Loosening problem is fastened caused by dynamic：
A kind of stop nut, include metal nuts body, described metal nuts body includes thread segment and construction section, in institute
Elastomer is provided with the construction section stated, internal thread is provided with shown elastomer, described internal thread originates spiral shell from thread segment
Away from gradual increase.
The latch assembly for preventing that elastomer from rotating is provided with described construction section and elastomer.
Described latch assembly includes being arranged on the breach on elastomer and sets the block on metal nuts body, described
In the described breach of block insertion.
Described minor diameter of internal thread is less than thread segment internal diameter.
Described elastomer material is nylon material.
It is using nut its advantage of above structure：Nylon elastomer structure is novel simple, and cost is low, anti-loosing effect
It is good, it is easy for construction, it is non-maintaining；Nylon elastomer material wear-resistant, intensity is big, can Reusability；Nylon elastomer material is non-gold
Category can increase coefficient of friction with bolt, serve the locking effect that rubs；Nylon elastomer inner ring pitch changes locking
Tooth is rotated simultaneously when nut rotates with nut, and the locking teeth of pitch change will be intermeshed with the tooth of bolt, can form interference
Coordinate, produce powerful reaction force, substantially increase the frictional force between internal and external threads, make the cooperation of bolts and nuts more
To be close, while also provide the absolute resistance to vibration, can preferably solve existing bolts and nuts due to being given a shock and
The problem of caused fastening loosens；Metal nuts coordinate with bolt can get rusty for a long time, cause difficult the problems such as dismantling unsightly, and
Can prevent that cylindrical one end of nut from entering water, dust etc. plus the stop nut of nylon elastomer, can effectively reduce nut and
The problem of bolt gets rusty after coordinating.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is elastomer structure schematic diagram；
Fig. 3 is elastomer sectional view；
Fig. 4 is the utility model section view.
Embodiment
Stop nut as shown in Figure 1 includes metal nuts body 1, and metal nuts body 1 includes thread segment 2 and construction section
3, elastomer 4 is provided with construction section 3, elastomer 4 as shown in Figures 2 and 3 is provided with internal thread 5, and internal thread 5 is through elasticity
Body 4 and from thread segment 2 originate pitch gradually increase.In order to prevent screw loosen nut when elastomer 4 rotate, in construction section 3
The latch assembly 6 for preventing that elastomer 4 from rotating is provided with elastomer 4, latch assembly 6 includes the breach 6-1 being located on elastic component 4
With the block 6-2 being located on metal nuts body 1, block 6-2 can be caught in breach 6-1, can be hindered so in rotary course
Elastic component 4 ensures that bolt is capable of the internal thread 5 of precession elastomer 4 in the internal rotation of construction section 3, due to internal thread 5 be pitch be by
Gradual change, and be to originate pitch from thread segment 2 gradually to increase, as Fig. 4 rotates when nut rotates with nut simultaneously, pitch
The locking teeth of change will be intermeshed with the tooth of bolt, can be formed interference fit, be produced powerful reaction force, greatly increase
Frictional force between internal and external threads, makes the cooperation of bolts and nuts more close, while also provide the absolute resistance to vibration
Power, can preferably solve the problems, such as that existing bolts and nuts fasten loosening caused by being given a shock, it is more preferable in order to reach
Interference fit, the internal diameter of internal thread 5 is less than the internal diameter of thread segment 2.Elastic component 4 above-mentioned is made of nylon material, nylon
Elastomer structure is novel simple, and cost is low, and anti-loosing effect is good, easy for construction, non-maintaining；Nylon elastomer material wear-resistant, intensity
Greatly, can Reusability；Nylon elastomer material can increase coefficient of friction to be nonmetallic with bolt, and it is locking to serve friction
Effect.
