Abstract
The utility model pertains to a metal part of a connecting and tightening machinery and relates to an anti-loosing self-locking washer of hardware products. The utility model is characterized in that the anti-loosing self-locking washer is provided with teeth forms on the upper face and the lower face; one face is provided with a big teeth form of 8 to 30 teeth; the angel Alpha of each tooth is larger than the angel Beta opposite to the thread of a bolt; the other face is provided with a small teeth form of 20 to 100 teeth. As the same two utility models which are adopted at the same time are a set with the faces of the two big teeth forms engaged with each other and the faces of the two little teeth forms contacting with the bolt or the nut and the tightened connector to screw up the bolt or the nut and to tighten the connector. When vibration appears, the two faces of the big teeth forms rotate relatively against each other; as angel Alpha is larger than angel Beta, the washer inflates to lock the bolt or the nut to prevent loosing and ensure the effects of tightening the connector of anti-vibration, anti-loosing and tightening. The utility model is characterized by reasonable design, simple structure and high practicability, etc., and can be used in combination with the traditional bolts and nuts, thus having wide applicability.
Description
Technical field the utility model belongs to metal and connects the fastening machines part, relates to the anti-loosening self-locking packing ring of a kind of hardware products.
Background technique is present, it is bolt, nut and gasket assembly that the metal that domestic tradition is used connects the fastening machines part, penetrate in the link by bolt, be equipped with nut screwing clamping by common circular washer or split ring packing ring and fix and constitute, the effect of packing ring is to prevent that bolts and nuts from getting loose.This fastening structure assembly very easily causes bolt, nut in the fastening structure to get loose under the situation that high temperature, dither impact, and produces the generation of device damage and accident, or brings the difficulty in the maintenance.
The summary of the invention the purpose of this utility model is can not become flexible under the situation that dither impacts for metal connection fastening machines equipment provides a kind of, but a kind of anti-loosening self-locking packing ring that repeated disassembled and assembled is used.
The anti-loosening self-locking packing ring of the utility model content Description:
The anti-loosening self-locking packing ring of the utility model is characterized in that: anti-loosening self-locking packing ring is that upper and lower faces has profile of tooth, and one side is big profile of tooth, and the number of teeth is 8～30, and the angle [alpha] of each tooth is greater than the β angle with respect to bolt thread; Another side is little profile of tooth, and the number of teeth is 20～100.
The anti-loosening self-locking packing ring of the utility model is because identical in use two form a cover, two big toothed surface are meshed relatively, two little toothed surface reach with fastened link with bolt (or nut) and contact, (or nut) fastening connection piece tights a bolt, when vibration occurring, relatively rotate between two big toothed surface, because the α angle makes this cover packing ring produce expansive force pinning bolt (or nut) greater than the β angle and makes it and can not become flexible, guaranteed the locking fastening effect of fastening connection piece antivibration.The utlity model has characteristics reasonable in design, simple in structure, practical, can be widely applicable with traditional supporting use of bolt, nut.
Description of drawings Fig. 1 is anti-loosening self-locking pad coil structures schematic representation
Fig. 2 is anti-loosening self-locking packing ring canine tooth shape face structural representation
Fig. 3 is the little toothed surface structural representation of anti-loosening self-locking packing ring
Among the figure: 1 is that anti-loosening self-locking packing ring, 2 is that anti-loosening self-locking packing ring canine tooth shape face, 3 is the little toothed surface of anti-loosening self-locking packing ring.
The anti-loosening self-locking packing ring of embodiment the utility model is achieved in that sees that Fig. 1, anti-loosening self-locking packing ring 1 are upper and lower faces, the last profile of tooth that has in two sides.See Fig. 2, the big toothed surface 2 of anti-loosening self-locking packing ring, the diameter of bore φ=10mm of anti-loosening self-locking packing ring, the number of teeth is 12, the angle [alpha] of each tooth is greater than the β angle with respect to bolt thread.See Fig. 3, be little toothed surface 3, the number of teeth is 48.Form a cover for identical in use two, two big toothed surface are meshed relatively, two little toothed surface reach with fastened link with bolt (or nut) and contact, (or nut) fastening connection piece tights a bolt, when vibration occurring, relatively rotate between two big toothed surface, because the α angle makes this cover packing ring produce expansive force pinning bolt (or nut) greater than the β angle and makes it and can not become flexible, guaranteed the locking fastening effect of fastening connection piece antivibration.
