Abstract
The utility model relates to a cone expansion anti-loosing unlocking bolt. The axial center of a bolt body is provided with a through hole (9), and a cone-shank shaft (2), a positioning pin (4), an anti-loosing nut (3) are arranged in the through hole. The anti-loosing nut is tightened to cause the cone body part of the cone-shank shaft to press a position changing claw (7) arranged on the end part of the bolt. Because of the action of a position changing slot (6), the position changing claw (7) is tightly inlaid in the threads of the nut to realize the goal of anti-loosing, and the position changing claw (7) can be unlocked by loosing the anti-loosing nut. The cone expansion anti-loosing unlocking bolt has the advantages of simple structure, convenient operation, reliable anti-loosing performance, easy fabrication, etc. The cone expansion anti-loosing unlocking bolt can bear continuous vibration impact force, so that the problems of automatic loosing of the bolt is solved.
Description
A kind of bolt, the especially locking release screw bolt of cone expanssion type, what relate to is the device technology field that fastening or fixed component of F16B or machine parts are used.
Bolt is a kind of fastening piece of extensive use.
In the public technology, the getting loose and be one of common disease of bolt.In order to prevent that bolt from getting loose, often adopt measures such as spring washer, pin.However, the harm that bolt looseness brought, the damage that has equipment, the generation that has accident.
So, bolt of the prior art, safety reliability is poor, and the consumption worker is consuming time during dismounting.
For overcoming deficiency of the prior art, the purpose of this utility model is to provide a kind of locking property reliable durable, and easy to use, the life-span is long, is easy to lock the locking release screw bolt of cone expanssion type with release.
Main technical schemes is:
Axial centre along axle key (1) is opened a through hole (9), and it is the taper-shank arbor (2) of screw thread for the taper shank the other end that an end is installed, and drives locating slot (5) at an end of the body of bolt (1), and displacement groove (6) forms displacement pawl (7).
The utility model can also reach by following other measures:
The taper shank of taper-shank arbor (2) is partly processed the difform cone of different amount;
At taper shank the locating stud (4) of multiple shape is installed partly, is fixed in the wherein groove of 2-16 locating slot (5).
Displacement groove (6) is processed into half garden shape of several odd numbers or even number, square, two interior shape, two profile, inside and outside all tangible;
The displacement pawl (7) of several odd numbers or even number is different amount, difform cone;
Lock nut (3) is to be tightened on the fastening bolt (8).
According to the utility model that technique scheme is implemented, have locking property reliable durable, easy to use, the life-span is long, be easy to lock and characteristics such as release.
Be the explanation of accompanying drawing of the present utility model and drawing below:
Fig. 1 is the front view of the locking release screw bolt of cone expanssion type;
Fig. 2 is that the A of bolt is to view;
Fig. 3 is the partial sectional view of bolt;
Fig. 4 is that the B of Fig. 3 is to view;
Fig. 5 is the front view of taper-shank arbor;
Fig. 6 is that the C of Fig. 5 is to view.
Wherein: 1 body of bolt, 2 taper-shank arbors, 3 lock nuts, 4 locating studs, 5 locating slots, 5 displacement grooves, 7 displacement pawls, 8 tightening nuts, 9 through holes.
The utility model is further described below in conjunction with drawings and Examples: car system one end is M36 * 63, and the other end is m30 * 72 metal single heads or stud bolt body (1), axially opens a φ 12 through holes (9) along it.
Passing the taper-shank arbor (2) of through hole (9), is different amount, difform cone, the garden shape of installation φ 3 on cone, locating stud (4).
After tightening nut (8) is tightened, tighten lock nut (3) more thereon, can arrive locking purpose, lock nut (3) is with No. 94114338.6 sour jujube tooth cone type jam nut patented products.
Loosening lock nut (3) gets final product release.
