Description
Technical field
The utility model relates to a kind of automatic elastic chek bolt, and particularly a kind of automatic elastic chek bolt on sheet material, belongs to machanical fastener technical field.
Background technique
Bolt by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, for being fastenedly connected two mechanical parts with through hole.As bolt is screwed out, can make again these two parts separately, therefore bolt connection belongs to removably connect, and is widely used on sheet material.When machinery is run, unavoidably mechanical vibration can be produced, long-term mechanical vibration cause bolt to rock, cause thread abrasion, the fastening effect of bolt 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 tapped hole deviate from by bolt, thus cause mechanical failure.
As Chinese utility model patent " a kind of chek bolt ", application number is 201220497162.7, disclose a kind of chek bolt, after screw rod screws in the tapped hole of sheet material, " L " shape switch block is rotated down 90 °, described " L " shape switch block “ –-" interior edge face in portion contacts with sheet material both side surface, due to " L " shape switch block “ –-" portion's interior edge face is provided with array multiple projection, play the effect of increasing friction force, when machinery runs generation mechanical vibration, bolt not easily rocks, make screw thread not easy to wear, add fastening effect, improve service behaviour and the stability of machinery.But when this bolt is in general state constantly, " I " portion upper surface of " L " shape switch block is higher than the upper surface of bolt head, and the space taken is large, extremely inconvenient when portably using; And in use, " L " shape switch block overturns, " L " shape switch block “ –-" before portion's interior edge face contact with sheet material both side surface, sheet material can extrude the several projection in outside, causes protruding wearing and tearing or damage, has had a strong impact on the anti-loosing effect of bolt.
Model utility content
The utility model object is that to provide one to take up room at ordinary times little in order to overcome the deficiencies in the prior art, can work as general bolt and use and the good automatic elastic chek bolt of anti-loosing effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic elastic chek bolt, comprise bolt body and two " L " shape switch blocks, described bolt body is formed by connecting by bolt head and screw rod, the upper surface of described bolt head has horizontal groove, and 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, is provided with receiving groove in described screw rod; Described receiving groove communicates with horizontal groove; The bottom of described receiving groove is provided with the cylinder that flexible rod protrudes upward; The flexible rod end of described cylinder is provided with pushing block; The upper surface of described bolt head is provided with the switch of control cylinder; " I " portions of described two " L " shape switch blocks near, be contained in receiving groove, the bottom in " I " portion of described " L " shape switch block contacts with pushing block; When " I " portion of described two " L " shape switch blocks is contained in receiving groove, " –-" portion upper surface of described " L " shape switch block is mutually concordant with bolt head upper surface, and " –-" portion outer side surface of described " L " shape switch block is mutually concordant with the outer side surface of bolt head; Gap is left bottom described protruding underpart and horizontal groove; " I " portion of described two " L " shape switch blocks can slide up and down in receiving groove; When " I " portion upward sliding of described two " L " shape switch blocks is to extreme higher position, can overturn downwards, " I " portion of described " L " shape switch block is positioned at horizontal groove, and " – " portion of described " L " shape switch block is parallel with screw rod; Described " L " shape switch block “ – " portion comprises fixed block, contiguous block and elastic member; Described contiguous block is arranged on the inner end of fixed block; Described elastic member connection fixing block and contiguous block; Described projection is arranged on the interior edge face of contiguous block.
Preferably, four annular grooves are provided with in described 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.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Automatic elastic chek bolt of the present utility model, even if the several projection in outside is because causing wearing and tearing or damaging with web contact, elastic member can support wearing and tearing or damage projection and contact with the both side surface of sheet material, keep contact force and the frictional force of projection and both side surface, ensure the anti-loosening property of bolt; 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 bolt generally used at ordinary times, portably use conveniently, can also work as general bolt and use, a bolt is multiplex.
