Description
Technical field
The present invention relates to a kind of automatic new-type check bolt, particularly a kind of new-type check bolt on sheet material, belongs to machanical fastener technical field.
Background technology
Bolt is by bolt head and screw rod (with an externally threaded cylinder) class securing member dimerous, for being fastenedly connected two machine components with through hole. As bolt is screwed out, can make again the two part separately, therefore bolt connection is belonging to removably connect, and is widely used on sheet material. When plant equipment is run, unavoidably can produce mechanical vibration, long-term mechanical vibration cause that bolt rocks, cause thread abrasion, the fastening effect making bolt is deteriorated, and have impact on the service behaviour of plant equipment and stability, particularly have impact on the machining accuracy of some precision equipments, it is also possible to occur bolt to deviate from the phenomenon of screwed hole, thus causing mechanical breakdown.
Such as Chinese utility model patent " a kind of check bolt ", application number is 201220497162.7, disclose a kind of check bolt, after screw rod screws in the screwed hole of sheet material, " L " shape switch block is rotated down 90 °, the inner face in the "-" portion of described " L " shape switch block contacts with sheet material both side surface, multiple projection is had owing to the "-" portion inner face of " L " shape switch block is provided with array, play the effect of increasing friction force, when plant equipment 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 plant equipment. 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 big, and it is extremely inconvenient to carry during use, and in use, " L " shape switch block overturns, before the "-" portion inner face of " L " shape switch block contacts with sheet material both side surface, sheet material can extrude the several projections in outside, causes protruding abrasion or damages, having had a strong impact on the anti-loosing effect of bolt.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art and provide one to take up room at ordinary times little, the automatic new-type check bolts that can prevent the several protruding abrasion in outside when general bolt uses or damage can be worked as.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of new-type check bolt, including 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, the bottom in " I " portion of described " L " shape switch block is fillet, and the "-" portion inner face of described " L " shape switch block is provided with array multiple projection, it is characterised in that: it is provided with holding tank in described screw rod; Described holding tank communicates with horizontal groove; The bottom of described holding tank is provided with the first cylinder that expansion link protrudes upward; The expansion link end of described first cylinder is provided with pushing block; The upper surface of described bolt head is provided with the first switch controlling the first cylinder; " I " portion of said two " L " shape switch block against, be contained in holding tank, the bottom in " I " portion of described " L " shape switch block contacts with pushing block; When " I " portion of said two " L " shape switch block is contained in holding tank, the "-" portion upper surface of described " L " shape switch block and bolt head upper surface flush, the "-" portion lateral surface of described " L " shape switch block and the lateral surface flush of bolt head; Gap is left bottom described protruding bottom and horizontal groove; " I " portion of said two " L " shape switch block can slide up and down in holding tank; When " I " portion of said two " L " shape switch block slides up to extreme higher position, can downwardly turning over, " 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; " " portion of described " L " shape switch block includes fixed block, contiguous block and the second cylinder; Described fixed block inner face is provided with multiple second cylinder; The expansion link end of described second cylinder is connected with contiguous block; Described projection is arranged on the inner face of contiguous block; The upper surface of described bolt head is provided with the second switch controlling the second cylinder.
Preferably, four annular grooves it are provided with in described holding tank; 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 holding tank, and when sliding into extreme higher position, can downwardly turn over.
Preferably, described cylinder is arranged with two.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The new-type check bolt of the present invention, " L " shape switch block overturns, before " " portion inner face of " L " shape switch block contacts with sheet material both side surface, sheet material will not touch the several projections in outside, avoid abrasion or the damage of projection, the power of stretching out of cylinder ensure that the protruding contact force with both side surface and frictional force, thus ensureing 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 holding tank so that easy and simple to handle; When not using, it is as good as with the bolt generally used at ordinary times, takes up room little, carry easy to use, additionally it is possible to when general bolt uses, a bolt is multiplex.
