Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model provides a combination gasket for preventing bolt is not hard up, including ring gear 3 and locking plate 2, the center of locking plate 2 begin to be equipped with the round hole that is used for the bolt to pass, the locking plate on the equipartition have the breach, the quantity of breach is more than 2 times of the stupefied face number of bolt head; one surface of the locking plate is a smooth surface, and the other surface of the locking plate is provided with a bulge; the hole in the center of the toothed ring 3 is used for a bolt to pass through, sawteeth are uniformly distributed on one surface of the toothed ring, and a recess corresponding to the protruding position on the locking plate 2 is formed in the other surface of the toothed ring.
In some embodiments, the locking piece 2 is ring-shaped.
In some embodiments, the annular locking piece has an area larger than an area of the bolt head.
In some embodiments, a plurality of protrusions are uniformly distributed on one surface of the locking piece 2.
In some embodiments, the number of notches is 2 times the number of bolt head faces.
In some embodiments, the protrusions on one side of the locking piece 2 are located on the same circumference.
As shown in fig. 1, when the head 1 of the bolt (for example, a right-hand screw) is rotated in a right-hand outward and left-hand inward direction, the bolt shank 5 gradually enters the inner depth of the connecting member 4 downward while being rotated. The bolt head 1 gradually compresses the locking plate 2 and the gear ring 3 and drives them to rotate in the same direction. Hereinafter, the rotation in this direction is referred to as forward rotation. Namely, the forward rotation is to tighten the bolt and the reverse rotation is to loosen the bolt.
As shown in fig. 3 and 4, the locking plate 2 is annular, and notches with the number of the ridges of the bolt head being 2 times or more integer times are cut equally to form spare areas with the number of the ridges being 2 times or more integer times that of the bolt head and available for locking (for a hexagon bolt, 12 notches are cut at minimum to form 12 spare areas). The surface of the locking plate 2 matched with the bolt head 1 is a smooth surface. The other surface is provided with a bulge (1 bulge is enough if the strength is enough, otherwise a plurality of bulges are uniformly distributed along the periphery, 4 bulges are shown in figures 3 and 4) and the corresponding concave pit on the toothed ring 3 are matched with each other, so that the locking plate 2 and the toothed ring 3 can not rotate relatively under the screwing state.
As shown in fig. 5 and 6, the surface of the toothed ring 3 which is matched with the locking plate 2 is smooth and provided with a pit. The surface matched with the connecting piece 4 is provided with sawteeth. When the bolt is tightened, part or all of the teeth of the toothed ring 3 will be embedded in the surface of the connecting piece 4.
As shown in fig. 2 and 7, after the bolt is tightened, there are 2 positions between the head 1 and the locking piece 2: the first is that the angle of the bolt head 1 is positioned on the slit of the locking plate 2; the second is that the angle of the bolt head 1 is located between the slit of the locking plate 2. For the case shown in fig. 2: all 12 spare areas can be tilted up for locking. For the case shown in FIG. 7: of the 12 spare areas, 6 can be tilted for locking. It can be seen that there are no fewer than 6 spare areas that can be tilted up for locking in any case.
In one embodiment of the present invention, when the bolt is tightened, the inclination angle of the teeth of the toothed ring plays a role in guiding and leading the toothed ring along with the forward rotation of the bolt. In addition, even if the relative rotation is not generated between the locking piece and the toothed ring and between the toothed ring and the connecting piece, the forward rotation of the bolt is not prevented, namely the bolt is not prevented from being tightened. Because the bolt head 1 and the locking plate 2 matched one side are smooth surfaces, the friction is small, and the bolt can not be more strenuous than screwing a conventional bolt.
The utility model discloses an in the embodiment after the bolt is screwed up, the inclination of sawtooth plays the prevention effect to the ring gear antiport, guarantees to screw up back ring gear 3 and can not the antiport. After being screwed down, the locking plate 2 and the toothed ring 3 can not rotate relatively, so that the locking plate 2 can not rotate reversely after being screwed down.
The utility model discloses an embodiment is after the bolt tightening, will be used to optional one of the regional a in the spare area of locking, c, e or regional b, d, f in both, along bolt head 1's stupefied line edge, will select 3 regional perks and paste its stupefied line edges, promptly to bolt head 1, every stupefied edge just forms one and prevents its pivoted hindrance, can reliably guarantee to tighten the back bolt and do not take place not hard up.
The utility model discloses an embodiment is when needs are dismantled, at first the perk region of locking plate is levelled, then with spanner counter-rotation bolt can. Because the matching surfaces of the bolt and the locking plate are smooth surfaces, the friction force is small, and the bolt and the locking plate are easy to disassemble. At the moment, even if the relative rotation between the locking plate and the toothed ring and between the toothed ring and the connecting piece is not generated, the reverse rotation of the bolt is not prevented just as the forward rotation of the bolt is not prevented.
The utility model has two anti-loosening functions, simple structure and convenient processing, and requires toughness for the key point of the lock piece 2; the hardness of the saw teeth is required for the gear ring 3, and the gear ring is reliable in looseness prevention and convenient to assemble and disassemble.
