Abstract
The utility model discloses a high strength bolt which comprises a threaded rod, a driving head, a groove and screw threads, wherein the driving head is arranged at the top end of the threaded rod; the groove is formed in the external surface of the threaded rod; the screw threads are formed on the external surface between the groove and the tail end of the threaded rod; the cross section of the groove is of an indented rectangle shape; the longitudinal length of the groove is 1/5 to 1/3 of the longitudinal length of the threaded rod; and the driving head is of an outer hexagon shape. According to the high strength bolt, as the whole rigidity of the bolt is reduced and the flexibility of the bolt is improved, the bolt can effectively absorb passive shock waves; the lateral and longitudinal vibration loads borne in operation are reduced; the high tangential load bearing capacity of the bolt is improved when a railway track is subjected to brake at a high speed; in addition, the high strength bolt is convenient for mounting and dismounting; the laying and maintenance time for the railway track is shortened; working hours of operation personnel are shortened; and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of high-strength bolt.
Background technique
Fastening piece is also referred to as standard piece on market; Be that two or more parts (or member) are fastenedly connected the general name that becomes the one type of mechanical parts that is adopted when seeing integral body; Be characterized in that description is various; The performance purposes is different, and standardization, seriation, unitized strong.Fastening piece is most widely used mechanical basic part, on various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous.Fastening piece comprises bolt, double-screw bolt, screw, nut, packing ring, pin, back-up ring, weldering nail, rivet, auxiliary connection, wood screw, tapping screw etc.Because specification, size, tolerance, weight, performance, surface condition, the labeling method of each concrete Fastener products; And the specific requirement of projects such as acceptance, sign and packing; Be separate provision in several countries (industry) standard, English system, German system and made in U.S.A are for example arranged.Along with the accession to WTO of China calendar year 2001 and step into the ranks of international trade big country.The Fastener products that China's Fastener products exports to countries in the world, countries in the world in a large number also constantly pours in Chinese market.Fastening piece is as one of bigger product of China's import and export amount, realizes in line with international standardsly, goes to the world to promoting Chinese fastening piece enterprise, promotes fastening piece enterprise to participate in international cooperation comprehensively and competes, and all tool is with important demonstration meaning and strategic importance.
Bolt is by head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous; Need to cooperate with nut; Be used to be fastenedly connected two parts that have through hole; This bolt connection screws off nut from bolt, can make these two parts separately again, is to belong to removably connect so bolt connects.
In railway transport, railroad track is the important component part of rail track, and it comprises rail, sleeper, binding part, railway roadbed, anti-creep equipment, rail brace and track switch etc.As an integrity engineering structure, track laying plays the leading role of train operation on roadbed, directly bear the immense pressure of rolling stock and load thereof.Under the dynamic action of train operation, its each constituent element must have enough intensity and stability, guarantees train maximum speed according to the rules, operation safely, steadily and incessantly.And, not only need high tenacity as the bolt that connects each parts on the track, and also to have certain pliability and impact resistance, also anti-slip simultaneously, could provide safeguard for safety of railway transportation property.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of high-strength bolt, improved driven bearing loading capability, impact resistant power, survivability and pliability, simple in structure, easy for installation.
The disclosed a kind of high-strength bolt of the utility model; Comprise screw rod, drive head, groove and screw thread; Described drive head is located at the top of screw rod, and the outer surface of described screw rod is provided with groove, and the outer surface between described groove and the screw rod end is provided with screw thread.
A kind of improvement of the disclosed a kind of high-strength bolt of the utility model, the cross section of described groove are the indent rectangle.
A kind of improvement of the disclosed a kind of high-strength bolt of the utility model, described groove longitudinal length are 1/5 to 1/3 of screw rod longitudinal length.
Another improvement of the disclosed a kind of high-strength bolt of the utility model, described drive head are outer-hexagonal shape.
The disclosed a kind of high-strength bolt of the utility model through the groove that is provided with, has reduced the integral rigidity of bolt; Improved the pliability of bolt, made bolt can effectively absorb passive shock wave, reduced and born operating horizontal and vertical vibrational loading; The indent rectangular cross sectional shape of groove, the heavy burden load-carrying ability of high tangential when having improved bolt and bearing railroad track and brake at a high speed is through the outer-hexagonal shape drive head that is provided with; With respect to the drive head of circle, more anti-skidding, be easy for installation and removal; Reduce the laying and the maintenance time of railroad track, reduced operator's operating time, improved working efficiency.
