Description
Technical field
The utility model relates to a kind of bolt, is specifically related to a kind of adjustable length bolt.
Background technique
Bolt is the fastening piece that daily life is commonly used, bolt head can be provided with hexangle type or cross groove, proper implements can be used to embed in these grooves bolt is carried out tightening or unscrewing, in routine use process, according to the demand of different use occasion, the effective length of bolt also can be different, the bolt that common occasion uses, mostly do not have strict to support the use specification, also the bolt obtaining the complete compound use of length is difficult to, bolt length is long then unsightly, dangerous, also can have influence on the fastening of bolt; If expose oversize, possible nut can not be engaged completely with screw rod.
Its helical pitch of conventional bolt and length are fixing, make a kind of rigid large, helical pitch is variable, and then the bolt making effective length variable, a bolt not only can be made to meet the user demand of multiple occasion, and can make better to be engaged according to use length between nut with screw rod, the fastening strength of strengthening stud.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of adjustable length bolt, and length and the helical pitch of the utility model bolt are variable, and a bolt can be made to meet the user demand of multiple occasion.
Following scheme is adopted in order to reach above-mentioned technical purpose the utility model:
A kind of adjustable length bolt, comprise fixing part and adjusting portion, described fixing part comprises bolt head and sleeve, bolt head is hexagon, bolt head is provided with through hole, and the lower end of bolt head is provided with columniform sleeve, and the axis of described bolt head, through hole and sleeve overlaps mutually; Described adjusting portion comprises adjusting head and screw rod, screw rod is provided with outside thread, described adjusting head is located at the top of screw rod, adjusting head is provided with hexangle type or cross groove, the inwall of described sleeve is provided with the internal thread matched with the outside thread on screw rod, described screw rod screws in downwards from the through hole of bolt head, the upper-end surface of adjusting head is concordant with the upper-end surface of bolt head, the lower end of sleeve is stretched out in the lower end of screw rod, and fixing part and the internal thread of adjusting portion on sleeve and the outside thread on screw rod match and spin.
Pass through technique scheme, of the present utility model can Changeable Lead bolt, be divided into fixing part and adjusting portion two parts, fixing part is the sleeve of a strap bolt head, bolt head with through hole can realize the screw-in of screw rod, during use, the adjusting head on screw rod only need be turned with screw-driver, screw rod is interior, move down in sleeve under externally threaded cooperation, this regulative mode, the effective length of bolt can be made elongated, the spiral shell journey exposed is elongated, a bolt not only can be made to meet the user demand of multiple occasion, and increase spiral shell journey and also can make between nut with screw rod according to use length be better engaged, the fastening strength of strengthening stud.
Further, the end of the novel described screw rod of this use is provided with and runs through screw rod and axially extended positioning hole, this axially extended through hole is mainly in order to coordinate the use of the nut of same belt transect positioning hole, after bolton, positioning hole on nut matches with the positioning hole on screw rod, use locating stud to run through nut and screw rod, the position of setscrew nut can be helped further, prevent bolt from use occurring getting loose; Positioning hole on screw rod uses axial extending design, makes this orientation type adjustable in circumferential direction, and location is more rationally firm.
Further, the length of the novel described screw rod of this use is length sleeve 1.2 ~ 1.8 times
The beneficial effects of the utility model are: 1. bolt head of the present utility model is provided with the hexagon bolt head that to match with electric screw driver, the rotation of bolt are installed more efficient and convenient.2. bolt of the present utility model is divided into fixing part and adjusting portion two parts, the screw-in that can realize adjusting portion screw rod of fixing part hollow, when the length of bolt needs to change, turn adjusting head, screw rod moves down under the cooperation of internal and external screw thread in sleeve, this regulative mode, the effective length of bolt can be made elongated, the spiral shell journey exposed is elongated, a bolt not only can be made to meet the user demand of multiple occasion, and increase spiral shell journey and also can make between nut with screw rod according to use length be better engaged, the fastening strength of strengthening stud.
