Description
Technical field
The present invention relates to a kind of automatic new-type lock nut, particularly a kind of automatic new-type lock nut on sheet material, belongs to machanical fastener technical field.
Background technique
Nut is exactly nut, is used for the part played the role of fastening with bolt or screw rod together with being screwed in, and is fastenedly connected two mechanical parts with through hole for playing.As bolt is screwed out nut, can make again these two parts separately, therefore this connection belongs to removably connect, and also can be widely used on sheet material.When machinery is run, unavoidably mechanical vibration can be produced, long-term mechanical vibration cause nut to rock, cause thread abrasion, fastening effect is deteriorated, have impact on service behaviour and the stability of machinery, particularly have impact on the machining accuracy of some precision equipments, also likely there is the phenomenon that nut thread hole deviate from by bolt, thus cause mechanical failure.
Summary of the invention
The present invention seeks to overcome the deficiencies in the prior art that to provide one to take up room at ordinary times little, the automatic new-type lock nut that can prevent the several projection wearing and tearing in outside when general nut uses or damage can be worked as.
For achieving the above object, the technical solution used in the present invention is: a kind of automatic new-type lock nut, comprises nut body, have tapped hole in described nut body, also comprise two " L " shape switch blocks; The bottom in " I " portion of described " L " shape switch block is fillet; Described " L " shape switch block “ –-" portion's interior edge face is provided with array multiple projection; On described nut body, symmetry has two horizontal slots; Described horizontal slot communicates with the external world; Described nut body also has the vertical receiving groove communicated with each horizontal slot; The bottom of described receiving groove is provided with the first cylinder that flexible rod protrudes upward; The flexible rod end of described first cylinder is provided with pushing block; The lower surface of described nut body is provided with the first switch of control first cylinder; " I " portion of described each " L " shape switch block is contained in a receiving groove, and the bottom in " I " portion of described " L " shape switch block contacts with pushing block; When " I " portion of described " L " shape switch block is contained in receiving groove, " – " portion of described " L " shape switch block is positioned at horizontal slot; " –-" portion upper surface of described " L " shape switch block is mutually concordant with nut body upper surface, and " –-" portion outer side surface of described " L " shape switch block is towards tapped hole direction; The width of described horizontal slot is greater than the width of " L " shape switch block; " I " portion of described " L " shape switch block can slide up and down in receiving groove; When " I " portion upward sliding of described " L " shape switch block is to extreme higher position, can overturn downwards; " I " portion of described " L " shape switch block is positioned at horizontal slot, " – " portion of described " L " shape switch block and the axis being parallel of tapped hole; Described " L " shape switch block “ – " portion comprises fixed block, contiguous block and the second cylinder; Described fixed block interior edge face is provided with multiple second cylinder; The flexible rod end of described second cylinder is connected with contiguous block; Described projection is arranged on the interior edge face of contiguous block; The lower surface of described nut body is provided with the second switch of control second cylinder.
Preferably, two annular grooves are provided with in described each receiving groove; The both sides in " I " portion of described " L " shape switch block are provided with cylindrical slider; Described slide block slides in chute, and " I " portion of " L " shape switch block slides up and down in receiving groove, and when sliding into extreme higher position, can overturn downwards.
Preferably, gap is left bottom described protruding underpart and horizontal slot.
Preferably, described second cylinder is arranged with two.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Automatic new-type lock nut of the present invention, projection can not touch sheet material, avoids protruding wearing and tearing or damage, and the power of stretching out of cylinder can ensure contact force and the frictional force of projection and both side surface, thus ensures the anti-loosening property of nut; During use, the pushing block that " I " portion of two " L " shape switch blocks is connected by cylinder releases receiving groove, makes easy and simple to handle; When not using, be as good as, take up room little with the nut generally used at ordinary times, portably use conveniently, can also work as general nut and use, one is female multiplex.
