Description
The utility model relates to a kind of shutoff device of restrict body or belt body, especially a kind of belt fastener or rope Quick Connect Kit with friction lock.
At present, sold on the market by the sealed belt of friction self-tightening mode (as Chinese patent 94224471.0) be to slide in the chute of the arc of the dual-side setting of belt fastener or inclination by a slide-bar, the slide-bar of tooth of synchronous belt leaves the belt release when being in low level, and the friction by belt when it is in a high position is locked.Its shortcoming is that slide-bar skids when using or in the chute of being everlasting, otherwise be exactly lock too tight release difficulty, the wearing and tearing of chute and slide-bar are very fast, make slide-bar locate or to deviate from and to lose efficacy after the wearing and tearing.
Chinese patent 92205464.9 have announced any adjustable type belt fastener of a kind of eccentric wheel, its main structure is at the belt fastener main body side lock body that an eccentric wheel constitutes to be installed, the piece that eccentric wheel one side is provided with a projection is pressed to belt body or is broken away from belt body as lever operated eccentric wheel and realizes padlock or release, this scheme needs hand rotation eccentric wheel locking belt body after inserting belt, because inconvenience operated in button by the protruding handle on the eccentric wheel and because the restriction of its size causes its releasing force limited.
The purpose of this utility model is just in order to solve the deficiency of the said goods and patent, and a kind of very strong coupling mechanism force that has is proposed, long service life, reliability is high and easy to operate, shutoff device simple in structure, the nothing that it can be used for belt is padlock extremely fast, also can be used for the quick connection or the locking of general rope, and dead bolt can be pressed to the belt body of padlock or the body and have automatic adjusting play one to adapt to the belt body or the rope body of different thickness or wearing and tearing of restricting automatically.
The purpose of this utility model is achieved in that the adjustable shutoff device of a kind of self-tightening that rubs, mainly comprise and withhold main body, withhold folding sheet, dead bolt, it is characterized in that: it is horizontal in withholding main body that elasticity is hinged with the axostylus axostyle of dead bolt, and the one or both ends of axostylus axostyle outside withholding main body are embedded with the folding hold down gag that dead bolt is rotated thereupon.
Described dead bolt is the special-shaped cam of cam or approximate triangle, has in the one side to have open slot on the diametral surface of axis hole one end and cause the both sides of groove to form the ears in tape spool hole.The face that cam contacts with belt body or rope body has and belt body or adaptive surface and the profile of tooth texture of rope body profile.
Described dead bolt can also be that the both sides bending is that U-shaped has the steel disc dead bolt that connects ears, and it connects ears and is provided with axis hole with the axostylus axostyle socket, and it is provided with the profile of tooth texture with belt body or restrict body profile adaptive arc-plane or concave surface.
Described withhold main body and dead bolt correspondence withhold main body also relative set for and belt body or rope body profile adaptive plane or arc-plane or semicircle, can also there be the profile of tooth texture on its surface for strengthening friction, and the low semicircular arc in preceding high back has the effect that stops the dead bolt excessive deflection.
Described closing device be the two ends of the square axostylus axostyle of cup head outside withholding main body with a folding of withholding main body socket outside withhold the sheet two ends that be provided with square hole or the nested realization of cylindrical void square axostylus axostyle coupling.Dead bolt on the horizontal square axostylus axostyle in withholding main body also is to realize by square opening and prism that is provided with on its ears and axostylus axostyle interlocking, and the square hole of lock tongue and the square axostylus axostyle that are nested on the square axostylus axostyle have the front and back free deflection approximately less than 45 elastic gap of spending.Square axostylus axostyle between the dead bolt ears is provided with an end and is wrapped in steel disc spring or the torsion spring that the elastic steel sheet on the square axostylus axostyle is made.One end of spring acts on and makes its stressed padlock main body of pressing on the dead bolt.The taper pin that the square axostylus axostyle other end is withheld sheet external application band cup head in folding is fixed or is riveted.
Described closing device can also be that the axostylus axostyle two ends of cup head square neck that is provided with and a folding of the withholding main body socket outside square hole or the cylindrical void that mate with the axostylus axostyle square neck of withholding that the sheet two ends are provided with is nested, section in the middle of the axostylus axostyle is circular, the circular shaft hole that circular axostylus axostyle is connected with dead bolt on the ears is hinged, folding withhold the sheet both sides below near dead bolt, connect a stull or inwardly establish a projection the limit it it can promote dead bolt and together rotates when causing the folding sheet to rotate, cylinder torsion spring one end that is provided with on the axostylus axostyle acts on the dead bolt, and the other end is stuck in the stull of withholding the setting of main body relevant position.The axostylus axostyle other end is fixed or is riveted at the taper pin of external application band cup head.
Described closing device can also be that axostylus axostyle end outside withholding main body becomes 90 degree to be fixed with an end of a folding plectrum, axostylus axostyle and folding plectrum junction be provided with one with axostylus axostyle on the hinged nested square neck in dead bolt one end square shaft hole, be with an end on the circular axostylus axostyle and act on cylinder torsion spring on the dead bolt, the other end of this spring is stuck in to be withheld in the stull that the main body relevant position is provided with.The axostylus axostyle other end passes the axis hole of withholding the main body other end and fixes or rivet at the taper pin of external application band cup head.
Also an end of the square axostylus axostyle of cup head is chimeric fixing by square shaft and the square hole of withholding main body one side relative set for described closing device, the square shaft bar other end is provided with one section section and is circular axostylus axostyle, this section circular shaft bar end that can on circular shaft bar rotate of pivot bush unit through withholding main body opposite side connecting hole and inserting outside fixedly installs the square shaft bar of a folding plectrum, dead bolt be hinged in two axis holes on the axostylus axostyle one be the circular hole that can on fixing square shaft, rotate or be nested in have on the square axostylus axostyle can make institute's tongue on square shaft before and after free deflection approximately less than the square hole in the gaps of 45 degree, another axis hole of dead bolt is the nested square hole of square shaft with rotary band folding plectrum, square axostylus axostyle between the dead bolt ears is provided with an end and is wrapped on the square axostylus axostyle steel disc spring by elastic steel sheet made adaptive with the axostylus axostyle profile, the other end of steel disc spring acts on and makes its stressed padlock main body of pressing on the dead bolt, and square shaft passes the axis hole of withholding the main body other end and fixes or rivet at the taper pin of external application band cup head.Certainly, the mode of establishing hole or groove installation cylinder torsion spring on axostylus axostyle of above-mentioned spring assembly also is fit to this example.
