Description
Technical field
The utility model relates to a kind of machanical fastener, particularly a kind of quick-release sphere supporting plate self-locking fastener that moves about.
Background technique
Since mechanical industry was come out, nut had just produced, and nut is with a long history, has become the fastening of a kind of extensive utilization
Part is as being extensive use of invariably on the instruments such as railway, bridge, electric power, mine, aircraft, tank, automobile.But plain nut in use, and particularly under alternation vibrations and high-frequency vibration, the fastening effect of nut can weaken, thereby loose voluntarily
Take off, easily have an accident.Institute thinks and prevents that nut from getting loose, reduce potential safety hazard, method commonly used at present is, the double nut back of the body is tight, increase spring washer or on nut method such as bayonet lock solve, these methods have not only increased the consumption of material, time-consuming, and of long duration still can get loose, fastening effect is still unreliable, there is potential safety hazard, often can't uses nut to connect in some occasion simultaneously, as nut being placed on desired area in narrow space, this situation occurring generally all is to pass through drilling and tapping, directly screw rod is screwed in then, such connection is prone to the phenomenon that produces stripped thread because of tapping position screw thread is less or along with vibrating the phenomenon that screw rod comes off voluntarily, it is very unreliable to connect.
The model utility content
The purpose of this utility model is, a kind of quick-release sphere supporting plate self-locking fastener that moves about is provided, and solving existing nut by the utility model does not have self-lock ability, more easily comes off and technical problem such as is inconvenient to be connected.
The technical solution of the utility model: a kind of quick-release sphere supporting plate self-locking fastener that moves about, it is by self-locking fastener (1), spherical surface body (2) and supporting plate (3) are formed, on self-locking fastener (1), be provided with six cylinders and interior threaded hole (6), and on six ribs of six cylinders of self-locking fastener (1), all offer the straight trough (4) that its interior threaded hole is closed up, be provided with the interior concaved circular cambered surface that cooperates with spherical surface body (2) in the bottom of self-locking fastener (1), be provided with the boss (5) of two symmetries in the outside, lower end of self-locking fastener (1), self-locking fastener (1) is buckled on the supporting plate (3) by boss (5), spherical surface body (2) is arranged between self-locking fastener (1) and the supporting plate (3), and the sphere of spherical surface body (2) contacts with the interior concaved circular cambered surface of self-locking fastener (1) bottom.
Go up and interior threaded hole (6) corresponding position offers through hole (7) greater than interior threaded hole (6) aperture in spherical surface body (2).
Corresponding position last at supporting plate (3) and interior threaded hole (6) offers the through hole (8) greater than interior threaded hole (6) aperture.
Through hole (8) both sides in supporting plate (3) also offer two positioning holes (9).
Compared with the prior art, the utility model is combined by self-locking fastener, spherical surface body and supporting plate, self-locking fastener is by slotting on hexahedral six interfaces, then its upper end-hole is pushed closing in, the screw of its epimere is diminished, the port generation resiliently deformable that when screw rod screws in, is extruded, increase the frictional force between screw thread, form self-lock force, sphere can make self-locking fastener freely move about in the above, the binding energy of going up lower peripheral surface simultaneously make between self-locking fastener and the link be positioned with certain between
The crack reaches self-centering action, and in the process that anti-system is become flexible, can slow down impact.Supporting plate is a carrier of the present utility model, and he links together self-locking fastener and spherical surface body, and the positioning hole on the supporting plate can be fixed on the utility model and need the screw rod connection part in advance simultaneously, can use at the position that fastening pieces such as nut can't be connected.Simultaneously self-locking fastener, spherical surface body and supporting plate are combined, can be mounted and dismounted simultaneously, exempt the similar operations such as pad, compression spring of setting level, so the utility model can be popularized and applied to various mechanical industries, good economic benefits and social benefit are arranged.
