Description
Technical field
The utility model relates to the provision for disengagement of screw, is specially adapted to the stripping attachment of door-plate deep hole screw.
Background technology
The device for dismounting screws such as fork spanner, double offset ring spanner, combination wrenches belong to conventional five metals device, for being embedded into door-plate (in door body or be embedded in the built-in plate of door, be different from the individual layer door-plate only having one deck, special finger compound door plant) deep hole hex bolts, then need to adopt special sleeve (sleeve bottom hollow, and the bolt head form fit of hollow profile and hex bolts).
Having there is a kind of deep hole stud in existing deep hole detent mechanism, by inserting a stud in deep hole, then adopts nut locking.Its Main Function utilizes the stud (still in deep hole) exceeding nut as an anchor point, if want to fix a certain object in the shop front, by relevant screwed pipe, can realize the connection of object and stud, thus be fixed in the shop front by object.
For fixed buildings, above-mentioned counterbore stud does not generally need to take out; But in recent years, market occurs between a large amount of mobile residences, locomotive, the Collapsible building such as portable communal bathroom, the move mode of these buildings is except overall consignment, and move mode is exactly first disassembled by whole building and then re-assembly to new place comparatively flexibly.Because each element of mobile building is standard component, can supplemental component nearby at any time, the assembly that will just not remove is transported to appointed place and assembles.But the prerequisite that its folding dress element of above-mentioned mobile building can reuse is that each assembly all adopts dismountable mode to connect.
Above-mentioned deep hole stud is also applied in Collapsible building, and the dismounting for deep hole stud is unsuitable for the electric drill adopting the existing band sleeve for hex bolts.Its concrete reason is, the degree of depth of its sleeve inner exceeds the length of nut not as good as described stud, and described sleeve cannot decline and stretch and nut place, causes sleeve cannot be connected with nut screw connection, is taken out by nut, and then stud also just can be stayed in deep hole always.
Utility model content
The utility model is intended to provide a kind of quick doornail driver-extractor being convenient to dismantle deep hole stud.
Quick doornail driver-extractor, comprise hand-held long handle and screw shell, the power end that described hand-held long handle top is handle or is connected with electric drill, it is threaded sleeve bottom hand-held long handle, and threaded sleeve outer wall is provided with the external screw thread be connected with screw shell inner thread, threaded sleeve inwall is provided with the internal thread be threaded with stud; The open slot that described screw shell is consistent with threaded sleeve being equipped with width, open slot length direction and screw shell and threaded sleeve axial consistent; Also comprise the scotch inserted in the lump in screw shell and threaded sleeve open slot, the width of described scotch is consistent with open slot.
Adopt the quick doornail driver-extractor of the utility model, there is following effect:
During concrete use, the utility model is threaded with screw shell, stud respectively by threaded sleeve, and scotch is inserted in screw shell and threaded sleeve open slot, between threaded sleeve with screw shell, relative rotation occurs for preventing;
Screw shell is put into deep hole bottom; Rotate threaded sleeve, stud is moved upward, and such stud is just separated gradually with nut, reaches the effect of dismounting.The utility model adopts two sections of thread segments to carry out height and regulates, screw shell first, second be threaded sleeve, both with the use of, compared with the screwed pipe of longer with single (threaded sleeve and screw shell length sum), whole stud can not enter in screwed pipe completely, is easy to stud to take out like this.
Further, threaded sleeve is provided with the uniform open slot of a plurality of circumference, and screw shell is provided with equal number and also circumferential uniform open slot; The quantity of scotch is identical with the quantity of threaded sleeve upper shed groove, each scotch upper end is connected on a ring set, hand-held long handle is provided with one group of locating hole vertically, and the spacing between adjacent positioned hole is equal with the helical pitch of threaded sleeve, and described ring set is positioned at locating hole place by tightening piece.
In order to each scotch being inserted in open slot corresponding to threaded sleeve, both screw shells position, need first the open slot of each threaded sleeve, screw shell to be aimed at, but for being threaded between threaded sleeve, screw shell, between threaded sleeve and screw shell while rotation, both also can move up and down, and threaded sleeve rotates a circle, threaded sleeve can move a helical pitch at axial location, the spacing of described locating hole is set to consistent with helical pitch value, makes scotch locate adjustment and matches with the rotation of threaded sleeve.
Explanation of nouns: helical pitch: the axial distance referring to adjacent two tooth corresponding points on same helix.Represent with code name S.It is different from pitch, and pitch refers to the axial distance of adjacent two tooth corresponding points on screw thread, and code name is P.Single threaded helical pitch equals pitch, and the helical pitch of multi start thread equals a number and takes advantage of in pitch.After threaded cylindrical or cylindrical shell rotate a circle, threaded cylindrical or cylindrical shell can move up or down the distance of a helical pitch.
Further, described tightening piece comprises top cover and heading, is provided with Compress Spring between described top cover and heading, and the interior profile of described locating hole is the cambered surface of mating with heading surface configuration, described ring set is provided with the through hole penetrated for tightening piece, and top cover is connected with described through hole whorl.
Press power between tightening piece and locating hole should not adopt the mechanical connection of rigidity, so adopt spring and spheroid, for the formation of elasticity compacting, is conducive to dismounting.
Further, the quantity of the open slot of described threaded sleeve and screw shell is two, and the quantity of described scotch is also two.
For the consideration of stress balance, the transmission that a meeting affects moment of torsion is only set.
