Abstract

The invention discloses a bolt with an adjustable bolt head. The bolt comprises the bolt head and a disk. A screw rod is integrally formed at the bottom of the bolt head. Three T-shaped struts which are arranged in a surrounding mode are integrally formed at the top of the bolt head, and three inverted-T-shaped clamping grooves are formed between the three T-shaped struts and the bolt head. A disk groove is formed among the inner side faces of the three T-shaped struts. An inserting hole is formed in the middle of the upper surface of the bolt head. The inserting hole is located in the bottom face of the disk groove, and penetrates through the bottom of the bolt head to extend to the inside of the screw rod. According to the bolt with the adjustable bolt head, a straight groove can be replaced due to the arrangement of the independent disk and the disk groove, the problem that a groove in the bolt head is damaged and accordingly unscrewing is difficult is solved, and the anti-theft function is further achieved. Three clamping strips are arranged on the side face of the disk in an equidistant mode, so that axial torsional force borne by the clamping strips is uniform when the disk rotates, and breakage cannot happen easily.

Description

A kind of adjustable bolt of bolt head
Technical field
The present invention relates to machine components technical field, be 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, the present invention 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.
Summary of the invention
It is an object of the invention 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, the present invention provides following technical scheme: 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 invention has the beneficial effects as follows: 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.
