Abstract
The utility model discloses a collapsible check bolt which is characterized in that it comprised a screw bolt body'a center through-hole disposed along the axial trace of the screw 'the tail end of which is provided with a cross recess. A threaded and a cap nut are also included, wherein the threaded is through the center through-hole of the screw'the upper part of which is slotted and with thread, the lower is of shape- pyramid. The cap nut cooperates with the thread part of the threaded. The utility model has the advantages that the structure is simple, it is convenient to use, and the anti-release capacity is strong. This invention is mainly used to the occasion that the connected member of blind hole, and the occasion of connecting through bolts is also available.
Description
Technical field
The utility model relates to a kind of standard fasteners, relates in particular to a kind of detachable chek bolt.
Background technique
Bolt Connection be connecting mode the most frequently used in the machinery.But,, often cause functions of the equipments to lose efficacy even damage because the influence of vibration of machinery causes bolt fastener loosening, even comes off in the occasion of many mechanical motion.At the bolt looseness problem, people take different locking measures, and as using spring washer etc., but it is unsatisfactory to be used on the bigger equipment of vibration its anti-loosing effect, and the accident that bolt looseness causes often has generation.Some chek bolt then adopts disposable locking measure, can not dismantle after the installation, gives to open and inspect to keep in repair and brings difficulty.
Summary of the invention
The utility model is a kind of detachable, the locking reliably detachable chek bolt that provides for the problem that overcomes existing bolt existence.
The technological scheme that the utility model is taked is: a kind of detachable chek bolt, be characterized in that comprise a bolt body, described bolt is provided with a central through bore along axis, and its tail end is provided with a cross recess; Also comprise a threaded and a nut; Described threaded is set in the central through bore of bolt, its top fluting, and epimere is threaded, and the bottom is a cone-shaped; The helical thread portion of described nut and described threaded is suitable.
Above-mentioned a kind of detachable chek bolt, wherein, described threaded slightly is longer than the length of bolt, and its cone-shaped is more smaller than bolt central through bore diameter with the diameter on top, can freely be set in the central through bore of bolt; The bottom of this threaded cone-shaped is than the slightly larger in diameter of bolt central through bore, and when this threaded was set in the central through bore of bolt, described cone-shaped had the central through bore oral area of part support at bolt.
The detachable chek bolt of the utility model is owing to adopted above technological scheme, threaded is passed center hole from the bolt tail end, it exposes the helical thread portion band upper cap nut of bolt head, after good coupled of Bolt Connection, with the nut screwing clamping of band on pin, again the threaded slotted head is partly used the instrument distending.Therefore, it compared with prior art has following tangible advantage and characteristics:
1. it is simple to overlap the chek bolt structural design, has very strong anti-loose ability.
2. be mainly used in coupled and be the occasion of blind hole, also can be used for wearing the occasion of Bolt Connection.
Description of drawings
Concrete structure of the present utility model is further provided by following indoor and accompanying drawing.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic representation of the detachable chek bolt of the utility model.
Fig. 2 is the worm's eye view of Fig. 1.
The structural representation that Fig. 3 is the detachable chek bolt of the utility model when coupled of blind hole form connects.
Embodiment
See also Fig. 1, Fig. 2.A kind of detachable chek bolt of the utility model comprises a bolt body 1, and described bolt body is provided with a central through bore 11 along axis, and its tail end is provided with a cross recess 12 (please cooperate referring to Fig. 2).Also comprise a threaded 2 and a nut 3; Threaded 2 slightly is longer than the length of bolt body 1, and its top is provided with fluting 21, and epimere is threaded 22, and the helical thread portion of described nut and described threaded is suitable.The bottom of threaded 2 is a cone-shaped 23.This threaded cone-shaped is more smaller than bolt body central through bore diameter D with the diameter d on top, can freely be set in the central through bore of bolt body; The base diameter of this threaded cone-shaped is than the slightly larger in diameter of bolt body central through bore, and when this threaded was set in the central through bore of bolt, some a support of described cone-shaped was at the central through bore oral area of bolt body.
See also Fig. 3, this is that the utility model is used for coupled the structural representation when being the blind hole form.Among the figure: A is a coupling, and B is coupled.Threaded 2 is passed central through bore 4 from bolt body 1 tail end, and the threaded top of threaded 2 is exposed bolt body 1 head, with threaded 2 helical thread portion band upper cap nuts 3.Behind the bolt body 1 fastening coupling, the nut on the threaded 23 is tightened, again threaded 2 slotted heads are partly used the instrument distending.During fastening nut 3, threaded 2 will produce pulling force at axial direction, because threaded 2 afterbodys are tapers, its diameter is greater than bolt body 1 center-hole diameter, so be screwed to certain position, threaded 2 afterbodys are bolt body 1 afterbody cross recess part distending, thereby have enlarged the threaded function diameter of bolt body 1 afterbody.The amount of exercise of the screw-in direction of nut 3 is many more, and the bottom functional diameter (FD) of bolt 1 screw thread is big more, thereby prevents the loosening of bolt body 1.If will pull down this chek bolt, slotted section need only be used the instrument clamping, unscrew nut, screw thread is withdrawed from getting final product.
The utility model is simple in structure, and is easy to use, reliable.
