Abstract
An anti-looseness machine washer comprises a machine washer body; a plurality of radial anti-looseness raised strips are arranged on each of the upper and the lower end surfaces of the machine washer body; and the radial anti-looseness raised strips on each end surface are distributed at equal intervals in the circumferential direction. The anti-looseness machine washer provided by the utility model has the advantages that since the plurality of radial anti-looseness raised strips are arranged on each of the upper and the lower end surfaces of the machine washer body, when a nut or a screw is screwed, namely when a nut or a screw head is compressed on the anti-looseness machine washer, the friction force between the nut or the screw and a connected part is increased under the action of the plurality of radial anti-looseness raised strips, further, the nut or the screw is prevented from loosening when under stronger vibration, and the requirement on locking is met.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of plain washer with locking function.
Background technique:
Plain washer is placed on nut or screw head usually and by between the union piece, its effect is to prevent that screw or nut from use becoming flexible.Mostly upper and lower two end faces of conventional plain washer are smooth plane, and this smooth plane makes itself and nut, screw head and very little by the frictional force between union piece, and when nut or screw received than strong vibration, nut or screw just were easy to take place to become flexible.
The model utility content:
The technical problem that the utility model will solve is, provides a kind of when nut or screw receive than strong vibration, can prevent better that nut or screw from loosening locking plain washer taking place.
The technical solution of the utility model is; A kind of locking plain washer with following structure is provided: comprise the plain washer body; Wherein, Be equipped with a plurality of radially locking raised items that move back on upper and lower two end faces of plain washer body, the radially locking raised item that moves back on each end face all is circumferentially equidistantly to distribute.
After adopting above structure; Compared with prior art; The locking plain washer of the utility model has the following advantages: since the plain washer body be equipped with a plurality of radially locking raised items that move back on two end faces up and down, therefore, behind nut or screw-driving; Be that nut or screw head are when being pressed on the locking plain washer of the utility model; Nut or screw and will under a plurality of radially locking effects of moving back raised item, be increased by the frictional force between union piece, thus effectively avoid nut or screw when receiving, to take place to become flexible than strong vibration, reach the requirement of locking.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the locking plain washer of the utility model.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the locking plain washer of the utility model is done further explain:
As shown in Figure 1; In this embodiment; The locking plain washer of the utility model comprises plain washer body 1, is equipped with a plurality of radially locking raised items 2 that move back on upper and lower two end faces of plain washer body 1, and the radially locking raised item 2 that moves back on each end face all is circumferentially equidistantly to distribute.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
Claims (1)
1. locking plain washer; Comprise plain washer body (1); It is characterized in that: be equipped with a plurality of radially locking raised items (2) that move back on upper and lower two end faces of said plain washer body (1), the radially locking raised item (2) that moves back on said each end face all is circumferentially equidistantly to distribute.
