Description
Technical field
This utility model relates to machine components technical field, is specially a kind of adjustable bolt of bolt head.
Background technology
Bolt is machine components, the threaded securing member of cylinder of adapted nut.By bolt head and screw rod (with an externally threaded cylinder) class securing member dimerous, need to coordinate with nut or screwed hole, i.e. for being fastenedly connected two parts with through hole.
All offer flat recess, cross recess or hex slot on the most most bolt head, then utilize instrument (straight screwdriver, Phillips screwdriver or die nut) to be turned by this flat recess, cross recess or hex slot and unscrew or tighten.But in the case of a lot, this province structural strength problem due to bolt, or the bolt strength step-down that bolt causes through life-time service, cause screwdriver or die nut cooperation during rotating bolt in flat recess, cross recess or hex slot, the cell wall of flat recess, cross recess or hex slot is deteriorated, thus cause bolt cannot be rotated by screwdriver and die nut, impact to daily life and production.
A kind of bolt is disclosed for solving the Chinese invention patent that this question patent Authorization Notice No. is CN2037967055U, including bolt head and screw rod, described screw rod is provided with draw-in groove relative to the side of bolt head, the fixture block suitable with draw-in groove it is provided with on described bolt head, described fixture block is detachably fixed and is embedded in draw-in groove and described fixture block is circumferentially positioned with draw-in groove, this utility model provides a kind of removable bolt of bolt head, it is to avoid occur that the groove on bolt head is difficult to situation about unscrewing after being destroyed.Although this bolt solves the groove on bolt head and is destroyed the problem being difficult to unscrew, but it realizes the replaceable of bolt head only by draw-in groove and fixture block cooperation, cause its stress the most uniform, stress surface is less, during use, fixture block easily axis twisting resistance because being subject to is excessive and rupture, and brings certain trouble to the life of people.
Utility model content
The purpose of this utility model is to provide a kind of adjustable bolt of bolt head, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of adjustable bolt of bolt head, including bolt head and disk, the bottom of bolt head is integrally formed with screw rod, the top of described bolt head is integrally formed with three T-shaped pillars around setting, and define the draw-in groove of three inverted T-shapeds between three T-shaped pillars and bolt head, disc slots is defined between the medial surface of three T-shaped pillars, the middle part of described bolt head upper surface offers jack, this jack is positioned at the bottom surface of disc slots, and jack runs through the bottom of bolt head and extends to the inside of screw rod.
Described disk is positioned at the inside of disc slots, and the upper surface of disk offers flat recess, the bottom of disk integrally formed with inserted link, this inserted link and jack grafting, the side of disk is angularly provided with three card articles, and three card articles respectively with three draw-in groove clampings.
Preferably, the bottom surface of described draw-in groove, the bottom surface of disc slots are positioned in same level with the upper surface of bolt head.
Preferably, described draw-in groove all connects with disc slots with jack.
Preferably, 1/6th of a length of spiro rod length of described inserted link.
Compared with prior art, the beneficial effects of the utility model are: the adjustable bolt of this bolt head, the replacing to flat recess is realized by arranging single disk and disc slots, not only solve the groove on bolt head and be destroyed the problem being difficult to unscrew, but also there is antitheft function, three card articles are equidistantly positioned the side at disk, make disk when rotating, the axial torsion power that card article is subject to is the most uniform, it is not susceptible to fracture, draw-in groove serves the effect to card article location, and draw-in groove is set to T-shaped, disk is made to rotate the most clockwise or counterclockwise, card article can be fixed by T-shaped pillar, facilitate the use of people, inserted link coordinates with jack, avoid about when disk uses or front and back rock, use more stable.
