Embodiment

Referring to figs. 1 through Figure 10, a kind of bearing pin rotation connection structure of the present invention, comprise fixed end 1, be installed on the bearing pin 2 on fixed end 1, and be rotatably installed in the rotation end on bearing pin 2, described fixed end 1 is provided with the depressed area of indent, on the bi-side of depressed area, be provided with relative bayonet socket I 12 and bayonet socket II 11, depressed area is provided with restricted entry 13 on the bottom surface near bayonet socket II 11 1 sides, described bearing pin 2 left end portion are inserted in bayonet socket I 12, right end portion is inserted in bayonet socket II 11, described bearing pin 2 is provided with elastic bumps 21 near a side of bayonet socket II 11, described elastic bumps 21 can coordinate and snaps in restricted entry 13.

Described bearing pin 2 left end outer rims are provided with axial raised line 25, are provided with the half-moon groove 14 passing for axial raised line 25 in described bayonet socket I 12.Axially the cooperation of raised line 25 and half-moon groove 14 can be so that bearing pin 2 installation directions be accurate, and can not deflect after fixing.

Described rotation end comprises that the card that rotates main body 3 and be fastened in rotation main body covers 4, is provided with the middle cavity road 31 passing for bearing pin 2 in described rotation main body 3.On described middle cavity road 31, be provided with the screens groove 32 coordinating with axial raised line 25.In the time rotating an angle of end rotation, axially raised line 25 correspondences snap in different screens grooves 32, thereby make to rotate end, remain on this angle, reach the fixing object of multi-angle.

The dead slot inserting is installed for convenience of bearing pin 2 in bayonet socket II 11 rears of described fixed end 1 depressed area, and the left end of bearing pin 2 is penetrated in bayonet socket I 12 by bayonet socket II 11 rear sections by dead slot place.

The right-hand member end of described bearing pin 2 is provided with the block 23 coordinating with bayonet socket II 11 ear end faces.

On described block 23, be fixed with the spring section 24 of extending along bearing pin 2 axial directions left, in described spring section 24, be provided with and deviate from the elastic bumps 21 that bearing pin 2 central directions extend outwardly.The bottom of described fixed end 1 is provided with the groove coordinating with spring section 24, is provided with the restricted entry 13 coordinating with elastic bumps 21 in groove.Groove coordinates with spring section 24 like this, and elastic bumps 21 coordinates with restricted entry 13, to bearing pin 2 axially, circumferentially carry out spacingly, make the installation of bearing pin 2 firm, can not produce and come off, rock.

For the ease of bearing pin 2, insert in bayonet socket I 12, moving axially of bearing pin 2 limited simultaneously, the taper or the taper type that coordinate with bayonet socket I 12 are arranged in described bearing pin 2 left end ends.

For the ease of bearing pin 2, insert in bayonet socket I 12, described bearing pin 2 left end ends are provided with through slot 22, and bearing pin 2 left end ends are formed can the local elastic structure that draws in or expand.When bearing pin 2 inserts in bayonet socket I 12, bearing pin 2 left end ends are local draws in, and after bearing pin 2 inserts in bayonet socket I 12, life size is recovered in bearing pin 2 left end ends, thereby coordinate, is stuck in bayonet socket I 12.When rotating end, axially raised line 25 is deviate from from rotate the screens groove 32 of holding, the now left end end of bearing pin 2 extruding is shunk, bearing pin 2 rotates an angle, when axially raised line 25 enters in next screens groove 32, life size is recovered in the left end end of bearing pin 2, and axially raised line 25 snaps in new screens groove 32.

During installation, bearing pin 2 left ends are penetrated in bayonet socket I 12 by bayonet socket II 11,31 rear sections, middle cavity road from dead slot, now the spring section 24 on block 23 moves along groove, elastic bumps 21 in spring section 24 snaps in restricted entry 13, the left end end of bearing pin 2 is stuck in bayonet socket I 12, and axially raised line 25 snaps in screens groove 32 and half-moon groove 14, and block 23 cooperations of bearing pin 2 right-hand members are stuck in bayonet socket II 11 places, thereby bearing pin 2 is fixed, has limited it and circumferentially rotated and move axially.

Certainly, the present invention, except above-mentioned mode of execution, can also have other structural distortion, and these equivalent technical solutions also should be within its protection domain.
