Abstract
The invention discloses a lock bolt. The lock bolt comprises a bolt head and screw rod, wherein the bolt head and the screw rod are connected into a whole, and a through groove is formed in the upper surface of the bolt head; two L-shaped rotating blocks are symmetrically arranged in the through groove; the top ends of I-shaped parts of the L-shaped rotating blocks are rotatably connected with a side plate of the through groove; when the I-shaped parts of the L-shaped rotating blocks are located in the through groove, transverse-line-shaped parts of the L-shaped rotating blocks face the screw rod; the thicknesses of the L-shaped rotating blocks are equal to the width of the through groove; and a plurality of bosses are arrayed on the inner end faces of the transverse-line-shaped parts of the L-shaped rotating blocks. The lock bolt provided by the invention uneasily gets loose when a mechanical device works and generate mechanical vibration, so that the thread is uneasily abraded, the fastening effect is improved, the working performance and the stability of the mechanical device are improved, specifically the machining precisions of a plurality of precision devices are guaranteed, and phenomenon that the bolt is separated from a threaded hole is further prevented.
Description
Technical field
The present invention relates to a kind of chek bolt, relate in particular to a kind of chek bolt for connecting working table and side plate.
Background technique
Bolt is used for being fastenedly connected two with the mechanical parts of through hole by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous.As bolt is screwed out, can make again these two parts separately, be to belong to removably connect so bolt connects, be widely used in connecting working table and side plate.When machinery is moved, unavoidably can produce mechanical vibration, long-term mechanical vibration cause bolt to rock, cause thread abrasion, so that the fastening deleterious of bolt, affected service behaviour and the stability of machinery, particularly affected the machining accuracy of some precision equipments, also the phenomenon that bolt is deviate from tapped hole might occur, thereby cause mechanical failure.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of chek bolt of avoiding screw thread to wear and tear because of mechanical mechanical vibration.
Technical solution of the present invention is achieved in that a kind of chek bolt, comprises bolt head and screw rod, and described bolt head and screw rod connect into an integral body, and the upper surface of described bolt head has groove; Be arranged with two " L " shape switch blocks in the described groove; The top of " I " section of described " L " shape switch block is connected with the side plate of groove is rotatable; " I " of described " L " shape switch block when section was positioned at groove, "-" section of described " L " shape switch block was towards the direction of screw rod; The thickness of described " L " shape switch block is identical with the width of groove; "-" section interior edge face of described " L " shape switch block is provided with array a plurality of projections.
Preferably, when " I " section of described two " L " shape switch blocks is vertical with groove, the exterior edge face of " I " section of described two " L " shape switch blocks near.
Preferably, " I " of described " L " shape switch block when section is positioned at groove, and the lower surface of "-" section of described " L " shape switch block is positioned at the lower surface below of bolt head.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Chek bolt of the present invention, under the general state, " I " section of " L " shape switch block is vertical with groove, screw in the tapped hole of worktable and side plate when screw rod after, L " shape switch block half-twist; the interior edge face of "-" section of described " L " shape switch block contacts with lower surface with the upper surface of worktable; because "-" section interior edge face of " L " shape switch block is provided with array a plurality of projections are arranged; play the effect of increasing friction force; when the machinery operation produces mechanical vibration; bolt is difficult for rocking, so that screw thread is not easy to wear, has increased fastening effect, service behaviour and the stability of machinery have been improved, special so that some precision equipment machining accuracies are guaranteed, and have prevented that more bolt from deviating from the generation of tapped hole phenomenon, have improved the Safety performance of machinery.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of chek bolt of the present invention;
Accompanying drawing 2 is another visual angle of chek bolt of the present invention;
Accompanying drawing 3 is the use phase diagram of chek bolt of the present invention;
Wherein: 1, bolt head; 2, screw rod; 3, groove; 4, " L " shape switch block; 5, projection.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of chek bolt shown in accompanying drawing 1,2 comprises bolt head 1 and screw rod 2, and described bolt head 1 and screw rod 2 connect into an integral body, and the upper surface of described bolt head 1 has groove 3; Be arranged with two " L " shape switch blocks 4 in the described groove 3; The top of " I " section of described " L " shape switch block 4 is connected with the side plate of groove 3 is rotatable; " I " of described " L " shape switch block 4 when one was positioned at groove 3, "-" section of described " L " shape switch block was towards the direction of screw rod, and the lower surface of "-" section of described " L " shape switch block 4 is positioned at the lower surface below of bolt head 1; When " I " section of described two " L " shape switch blocks 4 and groove 3 are vertical, the exterior edge face of " I " section of described two " L " shape switch blocks 4 near; The thickness of described " L " shape switch block 4 is identical with the width of groove 3; "-" section interior edge face of described " L " shape switch block 4 is provided with array a plurality of protruding 5.
Of the present invention a kind of chek bolt as shown in Figure 3, under the general state, " I " section of " L " shape switch block 4 is vertical with groove 3, after screw rod 2 screws in the tapped hole of worktable and side plate, L " shape switch block 4 half-twists; the interior edge face of "-" section of described " L " shape switch block 4 contacts with lower surface with the upper surface of worktable; have a plurality of protruding 5 because "-" section interior edge face of " L " shape switch block 4 is provided with array; play the effect of increasing friction force; when the machinery operation produces mechanical vibration; bolt is difficult for rocking, so that screw thread is not easy to wear, has increased fastening effect, service behaviour and the stability of machinery have been improved, special so that some precision equipment machining accuracies are guaranteed, and have prevented that more bolt from deviating from the generation of tapped hole phenomenon, have improved the Safety performance of machinery.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
