The invention discloses an anti-loosing clamping bolt set, which can effectively prevent a nut from loosing and is relatively easy to process. The anti-loosing clamping bolt set consists of a bolt (1) and a nut (11), and is characterized in that: the bolt (1) is divided into two parts, namely a fixed section bolt and an anti-loosing section bolt; the diameter of the fixed section bolt is more than that of the anti-loosing section bolt; the rotation directions of fixed section bolt external screw threads (2) and anti-loosing section bolt external screw threads (4) are opposite; an anti-loosing nut sleeve (5) passes through the anti-loosing section bolt and then is sleeved on the nut (11); the inner bottom face of the anti-loosing nut sleeve tightly presses against a fixed section bolt end face (3); and an anti-loosing nut (12) is tightly screwed on the anti-loosing section bolt to fix the anti-loosing nut sleeve (5). Figure 3 is the attached drawing of the instruction and the abstract.
Description
Technical field
The present invention relates to a kind of bolt external member, particularly a kind of locking clamping bolt external member.
Background technique
In order to prevent that connecting fastening piece takes place to become flexible in vibration and impact process, it is locking to need locking device to carry out.In the prior art, Chinese patent number is 201110125077.8, and patent name is the invention of " locking clamping bolt assembly ", can prevent nut loosening effectively, and its deficiency is: when bolt hour, the processing bolt internal thread is difficulty.
Summary of the invention
The objective of the invention is to solve the problem that exists in the existing technology " locking clamping bolt assembly ", proposed a kind of locking clamping bolt external member, it not only can prevent nut loosening effectively, and when bolt hour, processing also is easier to.
The objective of the invention is to realize like this: a kind of locking clamping bolt external member, form by bolt, nut, it is characterized in that: bolt is divided into holding part bolt and two parts of locking section bolt, and the holding part diameter of bolt is greater than the locking section diameter of bolt; Holding part bolt outside thread is opposite with locking section bolt external thread rotary veer; The lock nut sleeve passes locking section bolt sleeve on nut, and lock nut sleeve inner bottom surface is pushed against on holding part bolt end face, and lock nut is tightened on the locking section bolt lock nut sleeve is fixed.
In order to make locking clamping bolt external member locking more reliable, adopt between lock nut and the lock nut sleeve bottom surface and smear binder, pad upper spring packing ring, the methods such as locking plate or employing welding that add fix together.
Owing to adopted such scheme, the present invention not only can prevent nut loosening effectively, when bolt hour, processing also is easier to, and technology maturation is reliable, is convenient to society generalization.

Embodiment
Below will combine accompanying drawing that the present invention is described in further detail.
First kind of mode of execution of the present invention
With reference to Fig. 1, Fig. 2, Fig. 3.In Fig. 1,1 is the locking bolt that tightens up in the external member, and bolt 1 is divided into holding part bolt and two parts of locking section bolt, and the holding part diameter of bolt is greater than the locking section diameter of bolt.2 for to be arranged on the holding part bolt outside thread on the bolt 1, is used for fixing nut.3 for being arranged on the holding part bolt end face on the bolt 1.4 is locking section bolt outside thread, in the opposite direction with holding part bolt outside thread 2 screw thread rotation.
In Fig. 2,5 is the lock nut sleeve, and the shape of lock nut sleeve 5 and size match with nut outer shape and size.6 is the lock nut sleeve openings, and 7 is lock nut sleeve bottom surface, and 8 is lock nut sleeve bottom hole.Lock nut sleeve 5 can be enclosed within on the nut of bolt through lock nut sleeve openings 6.
In Fig. 1, Fig. 2, Fig. 3, bolt 1 tightens up with nut 11 after passing down object 10, last object 9.Loosening in order to prevent nut 11; Ut socket 5 is enclosed within on the nut 11 through lock nut sleeve openings 6; And lock nut sleeve inner bottom surface and holding part bolt end face 3 are pushed against, be tightened on the locking section bolt outside thread 4 lock nut sleeve 5 is fixing with lock nut 12 then.Because holding part bolt outside thread 2 is in the opposite direction with locking section bolt outside thread 4 screw thread rotation, when nut 11 is loosening, can drive lock nut sleeve 5, lock nut 12 rotations, and that lock nut 12 rotate more is tight more, thereby has prevented that nut 11 from becoming flexible.When lock nut 12 is loosening, can drive lock nut sleeve 5, nut 11 rotates, and that nut 11 rotate more is tight more, thereby has stoped lock nut 12 to become flexible.
Frictional force when contacting with lock nut sleeve bottom surface 7 in order to increase lock nut 12 prevents that lock nut 12 is loosening, between lock nut 12 and lock nut sleeve 7, is coated with binder, makes whole locking system more reliable.
Second kind of mode of execution of the present invention
With reference to Fig. 1, Fig. 2, Fig. 4, the frictional force when contacting with lock nut sleeve bottom surface 7 in order to increase lock nut 12 prevents that lock nut 12 is loosening, between lock nut 12 and lock nut sleeve bottom surface 7, is provided with spring washer 13 and flat gasket 14.Second kind of mode of execution of the present invention except that above-mentioned different with first kind of mode of execution, other mode of execution and first kind of mode of execution are identical.
The third mode of execution of the present invention
With reference to Fig. 1, Fig. 2, Fig. 5; Frictional force when contacting with lock nut sleeve bottom surface 7 in order to increase lock nut 12; Prevent that lock nut 12 is loosening, between lock nut 12 and lock nut sleeve bottom surface 7, be provided with locking plate 15, loosening in order to prevent lock nut 12.The third mode of execution of the present invention except that above-mentioned different with first kind of mode of execution, other mode of execution and first kind of mode of execution are identical.
The 4th kind of mode of execution of the present invention
With reference to Fig. 1, Fig. 2, Fig. 6; Frictional force when contacting with lock nut sleeve bottom surface 7 in order to increase lock nut 12 prevents that lock nut 12 is loosening, between lock nut 12 and lock nut sleeve bottom surface 7, welds; Be provided with solder joint 16, loosening in order to prevent lock nut 12.Outside the 4th kind of mode of execution difference of the present invention, other mode of execution and first kind of complete formula mutually of mode of execution had both guaranteed locking reliability, had guaranteed again when dismounting, can not damage link and connected piece.
