Abstract
The utility model relates to a hexagon stud which comprises a threaded rod. An orthohexagonal protruded rib is arranged on the outer circumferential face in the middle of the threaded rod and used as a head portion. First threads are arranged on the outer circumferential face of one end of the threaded rod from the end portion towards the head portion, and second threads are arranged on the outer circumferential face of the other end of the threaded rod from the end portion towards the head portion. Axial length of the first threads is bigger than that of the second threads. The outer circumferential face, located between the first threads and the head portion, of the threaded rod is provided with an annular check block. A locking cavity is formed between the annular check block and the head portion and enables a wrench to screw up the stud. Through the adoption of the scheme, the hexagon stud is convenient to use, and wide in application scope.
Description
Technical field
The utility model relates to a kind of bolt, is specifically related to a kind of hexagonal stud bolt.
Background technique
Nowadays, progress and development along with industry, hex head bolt and stud bolt generally have been applied to each technical field, it is main equipment that stud bolt mainly is used in main body, need installation accessories, such as visor, mechanical sealing base, deceleration frame etc., one end is screwed into main body, installs the other end band upper cap nut behind the annex, because annex is often dismounting, screw thread can wear and tear or damage, using stud bolt to change can be very convenient, and hex head bolt is mainly used in being fastenedly connected two with the part of through hole, yet, because growing industrial technology, these two kinds of bolts can't satisfy current needed intensity and degree easy to use.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of hexagonal stud bolt easy to use, applied widely.
For achieving the above object, the utility model provides following technological scheme: comprise screw rod, it is characterized in that: be provided with orthohexagonal convex tendon as head on the outer circumferential face at described screw rod middle part, described screw rod one end outer circumferential face is headward first screw thread that is provided with from the end, the other end outer circumferential face is headward second screw thread that is provided with from the end, described the first screw thread axial length is longer than the axial length of the second screw thread, the outer circumferential face of described screw rod between the first screw thread and head is provided with collar stop, consists of lock chambers between described collar stop and the head and screws bolt for spanner.
By adopting technique scheme, the hexagonal stud bolt has the function of hex head bolt and stud bolt simultaneously, and the setting of collar stop makes spanner can be resisted against collar stop and locks, make locking action convenient, and when the screw thread on both sides all is rotary with object, the lock chambers of also reserving collar stop stretches into for spanner stretches out, and the different axial lengths of the first screw thread and the second screw thread can make the hexagonal stud bolt be applicable to more and different occasions, and Applicable scope is wider.
The utility model further is set to: the hand of spiral of described the first screw thread and the second screw thread is opposite.
By adopting technique scheme, when making head be rotated by spanner on the contrary, the hand of spiral of the first screw thread and the second screw thread can lock the need locking object on both sides simultaneously, increase convenient degree, hexagonal stud bolt shell shell is connected between frame and the frame simultaneously, increases Applicable scope.
The utility model further is set to: described screw rod is made by the 40Cr steel.
By adopting technique scheme, the 40cr steel has certain toughness, plasticity and wear resistance after heat treatment, is fit to very much the usage requirement of hexagonal stud bolt, and the use of 40Cr steel extensively, is easy to buying and processing, brings very big facility to production.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment.
Embodiment
Such as Fig. 1-shown in Figure 2, the utility model discloses a kind of hexagonal stud bolt, comprise screw rod 1, be provided with orthohexagonal convex tendon as head 2 on the outer circumferential face at screw rod 1 middle part, screw rod one end outer circumferential face headward 2 is provided with the first screw thread 3 from the end, the other end is from headward second screw thread 4 that is provided with of end outer circumferential face, the first screw thread 3 axial lengths are longer than the axial length of the second screw thread 4, the outer circumferential face of screw rod 1 between the first screw thread 3 and head 2 is provided with collar stop 5, consist of lock chambers between collar stop 5 and the head 2 and screw bolt for spanner, the diameter of collar stop 5 is greater than or equal to head 2 diameters, the hexagonal stud bolt has the function of hex head bolt and stud bolt simultaneously, and the setting of collar stop 5 makes spanner can be resisted against collar stop 5 and locks, make locking action convenient, and when the screw thread on both sides all is rotary with object, the lock chambers 6 of also reserving collar stop stretches into for spanner stretches out, the different axial lengths of the first screw thread 3 and the second screw thread 4 can make the hexagonal stud bolt be applicable to more and different occasions, Applicable scope is wider, the hand of spiral of the first screw thread 3 and the second screw thread 4 is opposite, when making head be rotated by spanner on the contrary, the hand of spiral of the first screw thread 3 and the second screw thread 4 can lock the need locking object on both sides simultaneously, increase convenient degree, hexagonal stud bolt shell shell is connected between frame and the frame simultaneously, increase Applicable scope, screw rod is made by the 40Cr steel, the 40cr steel has certain toughness after heat treatment, plasticity and wear resistance, be fit to very much the usage requirement of hexagonal stud bolt, and the 40Cr steel uses extensively, be easy to buying and processing, bring very big facility to production.
