Preferably, the interlocking face is cricoid inclined surface.

Preferably, the angle between the inclined surface and the threaded shank is 85 degree to 88 degree.

Preferably, the angle between the inclined surface and the threaded shank is 87 degree.

Preferably, the anti-loose screw structure is stainless steel material.

Preferably, the junction of the side wall of the radial outer in the interlocking face and the screw terminal forms chamfering.

In order to achieve the above-mentioned another object, the utility model provides a kind of device with screw structural, including first Component, second component and an at least anti-loose screw structure have fixation hole on the first component, have on the second component There are outer surface and through-hole corresponding with the fixation hole, the anti-loose screw structure is as described above, the threaded shank passes through institute It is fixed on the fixation hole after stating through-hole, the interlocking face is at least partly embedded in the second component by the outer surface.

Preferably, the device with screw structural is filter, the first component is cavity, the second component For the cover board being incorporated on the cavity.

Preferably, the second component is aluminium material.

Compared with prior art, surface of the utility model screw terminal towards threaded shank include from its radial outer inwardly by Gradually close to the interlocking face of the root of screw terminal, interlocking face is configured as at least partially embedded connecting object；It effectively avoids preventing whereby The case where structure of loosening the screw a little loosens, meanwhile, effectively prevent the increase of cost and the reduction of efficiency.

Specific embodiment

For the content, construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment And attached drawing is cooperated to be explained in detail.

Fig. 1 to Fig. 5 is please referred to, the utility model discloses a kind of anti-loose screw structures 100, including screw terminal 10 and company The threaded shank 20 in the screw terminal 10 is connect, surface of the screw terminal 10 towards the threaded shank 20 includes from its radial outer Inwardly move closer to the interlocking face 11 of the root of the screw terminal 10；The interlocking face 11 is configured as at least partially embedded connection Object, that is to say, that at least radial outside in interlocking face 11 is embedded in connecting object.Specifically, interlocking face 11 radial outer with The junction of the side wall of screw terminal 10 forms chamfering 13.

Surface of the utility model screw terminal 10 towards threaded shank 20 includes inwardly moving closer to screw from its radial outer The interlocking face 11 of first 10 root, interlocking face 11 are configured as at least partially embedded connecting object；Locking spiral shell is effectively avoided whereby The case where silk structure 100 loosens, meanwhile, effectively prevent the increase of cost and the reduction of efficiency.

Fig. 1 and Fig. 2 are please referred to, in some embodiments, the interlocking face 11 extends inwardly to the root of the threaded shank 20 Portion；That is, it is interlocking face 11 that surface of the screw terminal 10 towards threaded shank 20 is substantially all.Specifically, interlocking face 11 with The junction of the root of threaded shank 20 forms chamfering 14.Certainly, not limited to this, for example, in some other embodiment, it is described Interlocking face 11 can also include the inside level between of diameter for being connected to the root and the interlocking face 11 of the threaded shank 20 Face (not shown).

In a preferred embodiment, the interlocking face 11 is cricoid inclined surface.

In a preferred embodiment, the angle between the inclined surface and the threaded shank 20 is 85 degree to 88 degree；Whereby Reach more preferably interlocking effect, further enhances the soundness of connection.

In a more preferred embodiment, the angle between the inclined surface and the threaded shank 20 is 87 degree.

In some embodiments, the anti-loose screw structure 100 is stainless steel material.

Incorporated by reference to Fig. 3 to Fig. 5, the utility model provides a kind of device with screw structural, including the first component 30, Second component 40 and at least an anti-loose screw structure 100 have fixation hole 31, the second component on the first component 30 There is outer surface 41 and through-hole 42 corresponding with the fixation hole 31, the anti-loose screw structure 100 is as described above, institute on 40 It states threaded shank 20 and is fixed on the fixation hole 31 after the through-hole 42, the interlocking face 11 is at least partly by the outer surface The 41 insertion second components 40.

Surface of the utility model screw terminal 10 towards threaded shank 20 includes inwardly moving closer to screw from its radial outer The interlocking face 11 of first 10 root, interlocking face 11 are at least partly embedded in the second component by the outer surface 41 when in use 40；The case where effectively avoiding anti-loose screw structure 100 from loosening whereby, meanwhile, effectively prevent the increase and efficiency of cost Reduction.

In some embodiments, the second component 40 is aluminium material.
