Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of adjustable chek bolt.
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 in connecting working table and side plate.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, also the phenomenon that tapped hole deviate from by bolt likely occurs, there is potential safety hazard, particularly some automobile and launch vehicle threaten the life of people directly or indirectly.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of safe and reliable, long service life, strong adaptability, the adjustable chek bolt that using scope is wide.
For achieving the above object, the utility model provides following technological scheme: a kind of adjustable chek bolt, comprise bolt body, described bolt body center is vertically arranged with center hole, on the screw rod of described bolt body, at least symmetry offers two adjustment holes be communicated with center hole, each adjustment hole built-in type is provided with locking device, described locking device comprises limiting stopper, Returnning spring and contiguous block, described Returnning spring one end and contiguous block are welded and fixed, the Returnning spring the other end and limiting stopper are welded and fixed, described contiguous block is positioned at adjustment hole the inner, limiting stopper is positioned at adjustment hole outer end, and contiguous block is positioned at the curved structure in center hole portion, an adjustable lever is plugged with in described center hole, by adjustable lever, contiguous block is moved to adjustment hole outer end, Returnning spring is to the outside thrust of limiting stopper one, and limiting stopper deviates from Returnning spring end is wholely set limited location projection.
By adopting technique scheme, locking device and adjustable lever arrange rationally, when center hole inserts adjustable lever, contiguous block is moved to adjustment hole outer end, Returnning spring is to the outside thrust of limiting stopper one, make the internal thread groove clamping of the spacing preiection on spacing block set and existing bolt hole, thus play the effect of increasing friction force, when machine produces mechanical vibration, bolt not easily rocks, and makes screw thread not easy to wear, add fastening effect, improve stability, safe and reliable, long service life, strong adaptability, using scope is wide.
The utility model is set to further: described adjustable lever upper end has been wholely set positioning plate, and described positioning plate forms " T " character form structure together with adjustable lever, and described positioning plate and bolt body upper-end surface removably connect.By this setting, positioning plate arranges rationally, and positioning plate is connected with bolt body reliably, and mounting or dismounting are convenient.
The utility model is also set to further: described positioning plate is at least symmetrically arranged with two screw holes, be equipped with a lock screw in each screw hole, described bolt body upper-end surface is aimed at each screw hole location and is offered the attachment hole mated with lock screw.By this setting, positioning plate is connected with bolt body reliably, and mounting or dismounting are convenient.
The utility model is also set to further: described limiting stopper is formed by stainless steel material manufacture.By this setting, limiting stopper not easily gets rusty, reliable operation.
The utility model is also set to further: the screw rod upper and lower of described bolt body is symmetrical arranged two adjustment holes be communicated with center hole respectively, and each adjustment hole built-in type is provided with a locking device.By this setting, locking device quantity arranges rationally, and anti-loosing effect is good.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, locking device and adjustable lever arrange rationally, when center hole inserts adjustable lever, contiguous block is moved to adjustment hole outer end, Returnning spring is to the outside thrust of limiting stopper one, make the internal thread groove clamping of the spacing preiection on spacing block set and existing bolt hole, thus play the effect of increasing friction force, when machine produces mechanical vibration, bolt not easily rocks, make screw thread not easy to wear, add fastening effect, improve stability, safe and reliable, long service life, strong adaptability, using scope is wide.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
