Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the invention provides a kind of locking mechanism.Particularly, locking mechanism 10 comprises bar portion 11, head 12 and back-up ring 14.Bar portion 11 is located on the first installation foundation, and head 12 is arranged at the one end in bar portion 11, and the edge of head 12 protrudes from the edge in bar portion 11, and back-up ring 14 is fastened in bar portion 11, and the first installation foundation is between head 12 and back-up ring 14.
Because back-up ring 14 is fastened in bar portion 11, first installation foundation is between head 12 and back-up ring 14, back-up ring 14 blocks bar portion 12 and comes off from the first installation foundation, bar portion 12 is made to be located on the first installation foundation all the time, the i.e. structural stability of locking mechanism 10, is arranged on all the time on the first installation foundation and can not drops.
As depicted in figs. 1 and 2, the locking mechanism 10 in the preferred embodiments of the present invention also comprises guide portion 15, and namely locking mechanism 10 comprises bar portion 11, head 12, screw thread 13, back-up ring 14 and guide portion 15.
The outer surface in bar portion 11 has screw thread 13, and head 12 is positioned at the one end in bar portion 11, and the edge of head 12 protrudes from the edge in bar portion 11.Head 12 is with straight groove 19 or cross recess, can make cylindrical or handle shape, is convenient to hand and holds or screw with a word or Phillips screwdriver.The periphery of head 12 is provided with reticulate pattern, straight knurling or becomes polygonal, is convenient to manually screw without during instrument, can realizes quick locking, unclamp fast.Preferably, head 12 is cylindrical, and head 12 and bar portion 11 are coaxially arranged, and the diameter of head 12 is greater than the diameter in columniform bar portion 11.Bar portion 11 is arranged with packing ring 60, and packing ring 60, between the first installation foundation and head 12, can avoid the coating sassafras on the first installation foundation to hinder.Packing ring 60 is made up of the nonmetallic material such as rubber or plastics.
Guide portion 15 is arranged on the other end in bar portion 11, and guide portion 15 and head 12 lay respectively at the two ends in bar portion 11.Guide portion 15 has guiding and dilates function, and guide portion 15 can be designed as inverted round stage or inverted cone or the hemisphere that falls.
In above-described embodiment, locking mechanism 10 can select the structure that screw and back-up ring 14 match, namely the structure that bar portion 11 and head 12 combine can select screw, this screw is made by metal or nonmetallic material, and tool has good wearability and preferably intensity and rigidity.
As shown in Figure 1, screw thread 13 protrudes from the outer surface in bar portion 11, and preferably, the intermediate portion in bar portion 11 has screw thread 13.Head 12 is cylindrical, and the diameter of columniform head 12 is greater than bar portion 11.Such design, make just to define annular stop groove 18 between the bottom of the top of screw thread 13 and head 12, the diapire of this annular stop groove 18 is exactly the partial outer face in bar portion 11.Back-up ring 14 is sheathed in the annular stop groove 18 formed between screw thread 13 and head 12, back-up ring 14 is also be fastened in this annular stop groove 18 simultaneously, preferably, back-up ring 14 can rotate in this annular stop groove 18, and the first installation foundation is between head 12 and back-up ring 14.
As shown in Figure 2, back-up ring 14 has back-up ring hole 141 and circlip groove 142.Back-up ring hole 141 is arranged in annular stop groove 18, and circlip groove 142 is connected with back-up ring hole 141 and circlip groove 142 extends along the radial direction in back-up ring hole 141.Particularly, one end of circlip groove 142 is connected with back-up ring hole 141, and the other end of circlip groove 142 is closed end.
The diameter in back-up ring hole 141 is less than the diameter of screw thread 13, the diameter in back-up ring hole 141 is also less than the diameter of head 12 simultaneously, so back-up ring 14 is set in bar portion 11, namely back-up ring 14 to be set in annular stop groove 18 and to be stuck in this annular stop groove 18, and back-up ring 14 can not come off from the bar portion 11 of locking mechanism 10 or head 12.Preferably, the diameter in back-up ring hole 141 is greater than the diameter in bar portion 11 slightly, like this can so that the rotation in bar portion 11.Locking mechanism 10 is arranged on the first installation foundation, and the first installation foundation is between the head 12 and back-up ring 14 of locking mechanism 10, and whole locking mechanism 10 can not fall down from the first installation foundation.
Certainly, back-up ring 14 can be fixedly installed on the first installation foundation, also can not be fixedly installed, and is only be set in bar portion 11.
As shown in Figure 2, circlip groove 142 is uniform along the circumference in back-up ring hole 141, and the angle between two that is adjacent circlip grooves 142 is identical.Circlip groove 142 is 3 to 5, and preferably, circlip groove 142 is 4, and 4 circlip grooves 142 are uniform along the circumference in back-up ring hole 141, and 4 circlip grooves 142 are in crossing distribution.The existence of circlip groove 142 makes back-up ring hole 141 to be expanded, and then back-up ring hole 141 relies on elastic recovery again, so circlip groove 142 can make back-up ring 14 easily via screw thread 13 and sheathed and snap in annular stop groove 18.
Back-up ring 14 is made up of metal or nonmetallic material, it is offered back-up ring hole 141, the structure of circlip groove 142 makes back-up ring 14 possess certain deformability, namely have elasticity.Back-up ring 14 rotation set is in bar portion 11, and whole locking mechanism 10 is arranged on the first installation foundation can not be lost again.
As shown in Figure 1, the bottom of head 12 has the sticking part 16 protruding from head 12 edge, and the part that sticking part 16 protrudes from head 12 is transitional surface 17.Sticking part 16 and head 12 are wholely set, and sticking part 16 can be fitted on the first installation foundation.The effect of transitional surface 17 is, is convenient to hand-screw and twists head 12, hand is played to the effect of support.
As shown in Figure 3, the invention provides a kind of door lock assembly.
Door lock assembly is arranged between the first installation foundation and the second installation foundation, for locking and unlocking the first installation foundation and the second installation foundation.
