Description
Technical field
The utility model is related to a kind of mining anti-loosening hybrid bolt and nut structure, it is adaptable in mineral engineering field
The anti-loosening of plant equipment etc. use, it can also be used to anti-loosening equipment is used the need for association area.
Background technology
Bolts and nuts are widely used in the assembling and connection of multiple industry devices as very important part.
Mineral engineering field plant equipment is numerous, particularly subsurface environment complex, this stability and security to plant equipment
Influence is great, then the anti-loosening effect to bolt, nut just proposes higher requirement.
More than existing mining industry field using elastic force pad withstand nut realize it is anti-loosening, but under complicated, many surging conditions, according to
The loosening of bolts and nuts can not be so avoided, once bolts and nuts loosen, the stability of equipment will be substantially reduced, therefore can band
Carry out sizable potential safety hazard.
The high anti-loosening bolts and nuts structure of strong adaptability, stability is developed, meaning is notable.
The content of the invention
The purpose of this utility model is that there is provided a kind of simple in construction, effect for the shortcomings of the prior art to be overcome
Fruit more preferable mining anti-loosening hybrid bolt and nut structure.
To achieve the above object, one kind of the present utility model mining anti-loosening hybrid bolt and nut structure, including double
Screw bolt, bolt, left-handed nut, right-handed nut, nut outer cover.
The screw thread of described double thread bolt is combined type screw thread, i.e., be right-handed thread close to screw head section, outer section is left-handed
Screw thread;Described right-handed nut is matched with right-handed thread, and described left-handed nut is matched with left hand thread.
There is bolt hole described left-handed nut side.
There is bolt hole the side of described nut outer cover.
In use, first right-handed nut is tightened in the right-handed thread section of bolt, left-handed nut is being tightened in a left side for bolt
Revolve thread segment, the bolt of final holding two nut alignings, the then bolt hole and left-handed nut of cover top nut cover and nut cover
Hole is alignd, and finally installs and tighten the bolt matched with the bolt hole of nut cover.
By nut outer cover, left-handed nut and the equidirectional rotation of right-handed nut can be limited, it is if right-handed nut loosens, i.e., right
Spin nut anticlockwise, then must by nut outer cover drive left-handed nut anticlockwise, so during right-handed nut's anticlockwise, it is left-handed
Nut also anticlockwise this can cause right-handed nut and left-handed nut move toward one another, inherently phase between left-handed nut and right-handed nut
Mutually extrude and can not rotate, thus can reach the purpose of anti-bolt, nut loosening.
Beneficial effect:By adopting the above-described technical solution, mining anti-loosening hybrid bolt and spiral shell of the present utility model
Parent structure, can well adapt to the complex environment in mine, effectively improve anti-loosening effect, and processing, property easy to use, safe
Height, with preferable applicability and practical value.

Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings:
As shown in Fig. 1,2,3,4,5,6,7,8,9,10, a kind of mining anti-loosening hybrid bolt and nut structure, including
Double thread bolt 1, bolt 5, right-handed nut 2, left-handed nut 3, nut outer cover 4, are made by metal material.
The screw thread of described double thread bolt 1 is combined type screw thread, i.e., be right-handed thread 1a close to screw head section, outer section is a left side
Revolve screw thread 1b;Described right-handed nut 2 is matched with right-handed thread 1a, and described left-handed nut 3 is matched with left hand thread 1b.
There is bolt hole 3b the described side of left-handed nut 3, described bolt hole 3b is matched with bolt 5;Outside described nut
The side of cover 4 has bolt hole 4b, described bolt hole 4b to be matched with bolt 5.
In use, first right-handed nut 2 is tightened in 1a sections of the right-handed thread of double thread bolt 1, tightened left-handed nut 3
In 1b sections of the left hand thread of double thread bolt 1, final retaining nut 3 is alignd with nut 2, then cover top nut cover 4 and nut cover
4 bolt hole 4b aligns with the bolt hole 3b of left-handed nut 3, finally installs and tightens bolt 5.
By nut outer cover 4, right-handed nut 2 and the equidirectional rotation of left-handed nut 3 can be achieved, if right-handed nut 2 loosens,
That is the anticlockwise of right-handed nut 2, then the anticlockwise of left-handed nut 3 must be driven by nut outer cover 4, so right-handed nut 2 is left-handed
When turning, left-handed nut 3 also anticlockwise this can cause right-handed nut 2 and the move toward one another of left-handed nut 3, right-handed nut 2, left-handed nut
Inherently mutually extrude and can not rotate between 3, thus can reach the purpose of anti-bolt, nut loosening.
Such as Figure 11 is use schematic diagram of the present utility model, that is, passes through mining anti-loosening hybrid bolt and nut structure is real
Existing fastening apparatus top 6 and equipment bottom 7, and the loosening of equipment can be prevented.
By adopting the above-described technical solution, mining anti-loosening hybrid bolt and nut structure of the present utility model, can
To well adapt to the complex environment in mine, anti-loosening effect is effectively improved, and it is processing, easy to use, safe, with good
Good applicability and practical value.
