Technical field
The present invention relates to a kind of fixed component with claim 1 preamble feature.
Background technique
By the known fixed component of open source literature DE 40 30 498 A1, component can be made to be fixed on immobilizing foundation by it.Fixed component is particularly useful for the parts of fixing substructure on the alien invasion plate be made up of lithotome or pottery.This fixed component is made up of handle bar, expanding ring, plastic disk and nut as expanding parts, and handle bar has outside thread and bores by expanding the expanding body formed.On the outside thread of handle bar, make plastic disk top companding rise ring and expanding ring is shifted onto on expanding cone by rotating nut, make expanding ring expanding thus and fixed component is fixed on inside the boring in immobilizing foundation.The defect of known fixed parts is, must by user by torque wrench tightening nut when being mounted with parts, and for ensureing, expanding ring is at boring the inside sufficiently expanding.
Summary of the invention
The object of the invention is, advise a fixed component, it assembles simplification.
This object is realized by the fixed component with claim 1 feature according to the present invention.Have handle bar according to of the present invention for the fixed component of securing part on immobilizing foundation, handle bar has outside thread and expanding body.These expanding parts especially add on direction to be arranged on above handle bar and taper, formed with the diameter expanded forward." forward " here relate to and adding the fixed component front end on direction, i.e. this end, it is adding fixed component according to schedule to bottom at foot of hole during boring the inside.The handle bar of described fixed component is especially made up of the bolt with the expanding cone expanded forward.Handle bar axially movably arranges expanding parts.These expanding parts can utilize expanding body expanding, and its method is that expanding parts are inserted on expanding body.Here " expanding " refers to described expanding parts and is diametrically expanding compared with non-expanding state, thus described expanding parts in order to fixing top pressure the wall of a borehole or positive be full of cutting of boring.In addition, described fixed component has nut, and it has internal thread, and it is arranged on the outside thread of handle bar.This nut by apply moment of torsion and can rotate on outside thread and thus in the axial direction on handle bar along moving, utilize thus nut make expanding overlap axially top to be pressed on handle bar and on expanding body mobile also expanding thus.
According to the feature of fixed component of the present invention be, described internal thread and/or outside thread are formed like this, make internal thread depart from outside thread like this after expanding parts expanding, described nut can not rotated, substantially with axial motion after nut departs from outside thread on handle bar.Therefore without using torque wrench tightening nut, because user feels after expanding parts expanding, internal thread and outside thread depart from, that is, outside thread and internal thread no longer engage each other, and nut can rotate thus, there is no axial motion.Therefore user knows, expanding parts sufficiently expanding and terminate the installation process of fixed component.
The backstopping assembly being used for nut is preferably set on described fixed component, when expanding parts be inserted into expanding body make and according to schedule expanding time, described backstopping assembly suppresses nut to continue motion in the axial direction.If nut leans on backstopping assembly, then nut no longer can axially move along handle bar towards expanding body by continuing to rotate, make nut pass through to continue to be rotated on outside thread to be out of shape so forcibly thus, make internal thread depart from engagement and nut " sliding tooth ".First make the moment of torsion that will apply to be rotated through user bring up to Maximum Torque by imposed deformation, wherein Maximum Torque is when sliding tooth, declines when internal thread and outside thread depart from again always.Declined by moment of torsion and send signal to user, expanding parts sufficiently expanding therefore terminate installation process.Described backstopping assembly such as can by as around the backstop shaft shoulder that forms on handle bar of endless belt form.Can select, expanding and the expanding parts leaned on expanding body work as backstopping assembly.
In addition preferred, the nut of described fixed component is made of plastics.Plastics are flexible and relatively soft, therefore described nut when exceeding the moment of torsion determined by externally threaded whorl side surface expansion and can elastomeric radial.Preferably polyamide is used for described nut.
In addition the handle bar of described fixed component is preferably made up of a kind of material, and this material is harder than the plastics for the manufacture of nut.This is particularly useful for externally threaded screw thread sideway stance.The handle bar of such as described fixed component is formed from steel.According in this special expansion structure of fixed component of the present invention, the internal thread of described nut when exceeding Maximum Torque and handle bar outside thread depart from, because of the nut radial expansion of being made up of relatively soft plastics and the internal thread of nut cut by the outside thread of hard handle bar and damage at least in part, until internal thread and outside thread depart from and nut cofree at handle bar, substantially do not rotate with axial motion.Rotating freely property is felt as slide nut tooth by user, the moment of torsion that wherein will apply reduction compared with Maximum Torque.Therefore user knows, expanding parts now fully expanding and terminate assembly process.
Replace can being specified by the nut of backstop imposed deformation, described outside thread terminates on expanding body direction and handle shank diameter reduces like this at this position, nut can be rotated freely, namely do not have compulsory axial motion.
In addition preferred, setting dish integratedly on the nut according to fixed component of the present invention.This dish is made of plastics especially equally, such as, jointly make in Shooting Technique with nut.Described dish can be pad, Balance disc and/or seal disc.Described dish makes fixed component be bearing on immobilizing foundation, compensating roughness and/or make boring prevent from sealing with clamp-oning moisture from outside.Realized according to the simple structure of fixed component of the present invention and the processing of cost advantages by integrality.
The outward edge of described dish preferably direction turns forward and is thin-walled adding.Described dish especially outwards, is namely retracted to tip diametrically to be parallel to the fixed component longitudinal axis that adds direction for benchmark.Because this expansion structure makes outward edge be resilient flexibility, this compensation for dish and/or sealing function are favourable.
According in another embodiment of fixed component of the present invention, described expanding parts are covers, have and are adding the expanding lug that direction is pointed to forward.By be made up of cover expanding parts realize, when described expanding lug according to schedule expanding time, expanding parts lean on expanding body on the position determined, make cover no longer continue to move on expanding body forward thus.Described in this position, the backstopping assembly overlapped as nut works, and nut directly or indirectly, such as passes through dish contact sleeve.Owing to being prevented nut axial motion generation nut from before sliding tooth, obviously increasing for the moment of torsion needed for rotating nut on outside thread by backstop, with the moment of torsion decline that will apply.Described cover is preferably formed as closed ring, and basic cover of getting rid of is due to the expanding when being improved moment of torsion by user of the axial force by nut effect thus.
Accompanying drawing explanation
Embodiment shown in utilizing below in the accompanying drawings explains the present invention in detail.
Accompanying drawing illustrates:
Fig. 1 is according to the axial section of fixed component of the present invention in non-expanding state; With
Fig. 2 is according to the side view of fixed component of the present invention in part expanding state.
Embodiment
Illustrate according to fixed component 1 of the present invention in fig 1 and 2, for fixing unshowned component at same unshowned immobilizing foundation.Fixed component 1 is made up of handle bar 2, expanding parts 3 and nut 4, forming disk 5 integratedly on nut.
Handle bar 2 is made up of cone bar, and have cylindrical section, it extends and has outside thread 6 on fixed component 1 longitudinal axis L direction, connects forward expanding body 7 adding on the E of direction thereon.Expanding body 7 is shaped by taper type cone, and it is diametrically expanding adding on the E of direction.Expanding parts 3 are covers 8, and it forms the ring closed, and arranges the expanding lug 9 of sheet thereon integratedly, and its free end forms the front end of expanding parts 3.Expanding lug 9 rounding and have perforate 10 respectively on its front end, its Central places is arranged in the surface of each expanding lug 9.Not only handle bar 2 but also expanding parts 3 are all formed from steel.
Nut 4 and the dish 5 that is wholely set on nut 4 are said be made up by plastics, accurately of polyamide, and the material that the handle bar 2 of fixed component 1 plastics of making nut 4 by a kind of ratio are harder is thus made.Nut 4 has forward hollow cylinder engaged section adding on the E of direction, and its external diameter reduces, and this external diameter corresponds to the external diameter of expanding body 7 and the expanding parts 3 of non-expanding thus.The dish 5 of connecting ring band shape in engaged section 11, it is radially beyond engaged section 11.The rearward end of nut 4 forms turning effort measure 12, and it is made up of outer six ribs with wrench faces 13.Dish 5 by around, the endless belt of ring forms, it extends orthogonally with longitudinal axis L on radial R.Dish 5 is formed adding under side, the front end fovea superior on the E of direction at it, makes the outward edge 14 of dish 5 turn forward thus and is thin-walled.Outward edge 14 is also outwards retracted to tip, and it can be easily deformable thus, coils also plane earth thus and leans on the immobilizing foundation of injustice.Nut 4 has internal thread 15, and it is connected with outside thread 6 function of handle bar 2, and nut 4 can be travelled forward adding on the E of direction by be rotated on handle bar 2 on sense of rotation D thus.
Expanding parts 3 are axially arranged on handle bar 2 movably along longitudinal axis L.By applying moment of torsion in the turning effort measure 12 of nut 4, nut 4 can be screwed on outside thread 6 adding on the E of direction, and wherein expanding parts 3 move towards expanding body 7.Making expanding parts 3 be inserted on expanding body 7 by continuing rotating nut 4, making expanding parts expanding thus, wherein the free end radial outward movement of expanding lug 9, as seen in fig. 2.After expanding, expanding parts 3 plane earth leans on the expanding body 7 of taper, and expanding parts 3 also can not continue to move adding on the E of direction by continuing rotating nut 4 thus.Lean on expanding body 7 and the expanding parts 3 of expanding in this expanding state and form backstopping assembly 16 for nut 4, it prevents nut 4 from continuing motion adding on the E of direction.The continuation of nut 4 on handle bar 2 rotates and first causes increasing for the moment of torsion needed for rotating nut 4.Be out of shape in the nut semi-finals that this is relatively softer than handle bar 2, such as, expand, internal thread 15 is damaged by outside thread 6, and internal thread 15 and outside thread 6 depart from so thus, and nut 4 is not rotated substantially with axial motion on handle bar 2.After internal thread 15 and outside thread 6 depart from, the moment of torsion that will apply for rotating nut 4 can decline with feeling, this sends signal to user, and fixed component 1 conforms with the regulations, earth anchor is connected on inside immobilizing foundation the complete expanding of expanding parts 3.Therefore, compared with fixed component that is known, that must pass through torque wrench expanding at present, the assembling according to fixed component 1 of the present invention is significantly simplified.
