Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
The automatic new-type stop nut of one of the present invention as shown in accompanying drawing 1,2, including nut body 1, has screwed hole 2 in described nut body 1, also includes two " L " shape switch blocks 3；The bottom in " I " portion of described " L " shape switch block 3 is fillet 4；The "-" portion inner face of described " L " shape switch block 3 is provided with array multiple protruding 5；On described nut body 1, symmetry has two level troughs 6；Described level trough 6 communicates with the external world；Described nut body 1 also has the vertical holding tank 7 communicated with each level trough 6；The bottom of described holding tank 7 is provided with the first cylinder 8 that expansion link protrudes upward；The expansion link end of described first cylinder 8 is provided with pushing block 9；The lower surface of described nut body 1 is provided with the first switch 10 controlling the first cylinder 8；" I " portion of described each " L " shape switch block 3 is contained in a holding tank 7, and the bottom in " I " portion of described " L " shape switch block 3 contacts with pushing block 9；When " I " portion of described " L " shape switch block 3 is contained in holding tank 7, " " portion of described " L " shape switch block is positioned at level trough 6, the "-" portion upper surface of described " L " shape switch block 3 and nut body 1 upper surface flush, the "-" portion lateral surface of described " L " shape switch block 3 is towards screwed hole 2 direction；The width of described level trough 6 is more than the width of " L " shape switch block 3；" I " portion of described " L " shape switch block 3 can slide up and down in holding tank 7；When " I " portion of described " L " shape switch block 3 slides up to extreme higher position, can downwardly turn over；" I " portion of described " L " shape switch block 3 is positioned at level trough 6, and " " portion of described " L " shape switch block 3 is parallel with the axis of screwed hole 2；In said structure, in described each holding tank 7, it is provided with two annular grooves 11；The both sides in " I " portion of described " L " shape switch block 3 are provided with cylindrical slider 12；Described slide block 12 slides in chute 11, and " I " portion of " L " shape switch block 3 slides up and down in holding tank 7, and when sliding into extreme higher position, can downwardly turn over；" " portion of described " L " shape switch block 3 includes fixed block 13, contiguous block 14 and the second cylinder 15；Described fixed block 13 inner face is provided with multiple second cylinder 15；The expansion link end of described second cylinder 15 is connected with contiguous block 14；Described protruding 5 inner faces being arranged on contiguous block 14；The lower surface of described nut body 1 is provided with the second switch 16 controlling the second cylinder 15；Leave gap due to bottom described protruding 5 bottoms and level trough 6, it is ensured that protruding 5 not with produces bottom level trough 6 to touch, it is to avoid projection 5 is worn.
nullSuch as accompanying drawing 3、The automatic new-type stop nut of one of the present invention shown in 4，During use，After the screw rod of bolt 17 inserts sheet material 18，Press the first switch 10，The expansion link of the first cylinder 8 stretches out，Drive pushing block 9 that " I " portion of two " L " shape switch blocks 3 is released holding tank 7，Then two " L " shape switch blocks 3 are overturn，" I " portion making " L " shape switch block 3 is positioned at level trough 6，Then nut body 1 is screwed on the screw rod of bolt 17，After screwing，Press second switch 16，Second cylinder 15 starts，The expansion link of the second cylinder 15 stretches out，Contiguous block 14 is driven to move to sheet material 18 direction，So that the protruding bottom of 5 contacts with the both side surface of sheet material 18，Play the effect of increasing friction force，When plant equipment runs generation mechanical vibration，Nut not easily rocks，Make screw thread not easy to wear，Add fastening effect，Improve service behaviour and the stability of plant equipment，So that some precision equipment machining accuracies are guaranteed，Bolt is more prevented to deviate from the generation of nut thread hole phenomenon，Improve the security performance of plant equipment；Time nut body screws on the screw rod of bolt, have gap between protruding and sheet material, it is to avoid protruding because of with web contact and cause abrasion or damage, simultaneously because the power of stretching out of cylinder, ensure that the protruding contact force with both side surface and frictional force, it is ensured that the anti-loosening property of nut；After use, unloading nut body, then press switch, the expansion link of cylinder shrinks, and " I " portion of two " L " shape switch blocks 1 is put into holding tank；When this nut does not use, " I " portion of " L " shape switch block is contained in holding tank, when " I " portion of " L " shape switch block is contained in holding tank, " " portion of " L " shape switch block is positioned at level trough, and the "-" portion lateral surface of " L " shape switch block is towards screwed hole direction, the "-" portion upper surface of " L " shape switch block and nut body upper surface flush, it is as good as with the nut generally used at ordinary times, takes up room little, carry easy to use, can also working as general nut to use, one is female multiplex.
The automatic new-type stop nut of the present invention, during use, the pushing block that " I " portion of two " L " shape switch blocks is connected by cylinder releases holding tank so that easy and simple to handle, reduces the labor intensity of operator, adds work efficiency.
Above-mentioned automatic new-type stop nut, when described each " L " shape switch block is arranged with two the second cylinders, stretches out power the best, and the anti-loosening property of nut is also best.
Above-described embodiment is only for illustrating technology design and the feature of the present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalences made according to spirit of the invention change or modify, and all should be encompassed in protection scope of the present invention.
