Description
Technical field
The present invention relates to a kind of chek bolt, particularly a kind of 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 overturn downwards, 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.
Summary of the invention
The present invention seeks in order to overcome the deficiencies in the prior art provide a kind of take up room at ordinary times little and can work as general bolt use chek bolt.
For achieving the above object, the technical solution used in the present invention is: a kind of 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, 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; " I " portions of described two " L " shape switch blocks near, be contained in receiving groove; 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.
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 present invention compared with prior art has following advantages:
Chek bolt of the present invention, when not using, is as good as with the bolt generally used at ordinary times, takes up room little, portably use conveniently, and can also work as general bolt and use, a bolt is multiplex.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of chek bolt of the present invention;
Accompanying drawing 2 is another viewing angle constructions schematic diagram of chek bolt of the present invention;
Accompanying drawing 3 is the using state schematic diagram of chek bolt of the present invention;
Wherein: 1, " L " shape switch block; 2, bolt head; 3, screw rod; 4, horizontal groove; 5, fillet; 6, protruding; 7, receiving groove; 8, chute; 9, slide block; 10, sheet material.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Of the present invention a kind of chek bolt as shown in accompanying drawing 1,2, comprise bolt body and two " L " shape switch blocks 1, described bolt body is formed by connecting by bolt head 2 and screw rod 3, the upper surface of described bolt head 2 has horizontal groove 4, the bottom in " I " portion of described " L " shape switch block 1 is fillet 5, described " L " shape switch block 1 “ –-" portion's interior edge face is provided with array multiple protruding 6, is provided with receiving groove 7 in described screw rod 3; Described receiving groove 7 communicates with horizontal groove 4; When not using, " I " portions of described two " L " shape switch blocks 1 near, be contained in receiving groove 7; When " I " portion of described two " L " shape switch blocks 1 is contained in receiving groove 7, " –-" portion upper surface of described " L " shape switch block 1 is mutually concordant with bolt head 2 upper surface, and " –-" portion outer side surface of described " L " shape switch block 1 is mutually concordant with the outer side surface of bolt head 2; Gap is left bottom described protruding 6 underparts and horizontal groove 4; " I " portion of described two " L " shape switch blocks 1 can slide up and down in receiving groove 7; When " I " portion upward sliding of described two " L " shape switch blocks 1 is to extreme higher position, can overturn downwards, " I " portion of described " L " shape switch block 1 is positioned at horizontal groove 4, and " – " portion of described " L " shape switch block 1 is parallel with screw rod 3; In said structure, in described receiving groove 7, be provided with four annular grooves 8; The both sides in " I " portion of described " L " shape switch block 1 are provided with cylindrical slider 9; Because described slide block 9 slides in chute 8, " I " portion of " L " shape switch block 1 slides up and down in receiving groove 7, and when sliding into extreme higher position, can overturn downwards.
Of the present invention a kind of chek bolt as shown in Figure 3, during use, when screw rod 3 screws in after in sheet material 10, from gap, two " L " shape switch blocks 1 are pulled out rear upset, the underpart of protruding 6 is contacted with the both side surface of sheet material 10, 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, some precision equipment machining accuracies are made to be guaranteed especially, bolt is more prevented to deviate from the generation of tapped hole phenomenon, improve the Safety performance of machinery, but, when this bolt does not use, " I " portions of two " L " shape switch blocks near, be contained in receiving groove, when " I " portion of two " L " shape switch blocks is contained in receiving groove, " –-" portion upper surface of " L " shape switch block is mutually concordant with bolt head upper surface, " –-" portion outer side surface of " L " shape switch block 1 is mutually concordant with the outer side surface of bolt head, be as good as with the bolt generally used at ordinary times, take up room little, portably use conveniently, can also work as general bolt and use, a bolt is multiplex.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
