Abstract

The utility model relates to a ball head bolt. The ball head bolt comprises a screw, wherein a spherical block is arranged at one end of the screw, one end of the spherical block, which is far away form the screw, is provided with an installation platform which is perpendicular to the axial direction of the screw, a thread is arranged on the outer peripheral face of the other end of the screw, a rib with an orthohexagonal peripheral face is arranged on the outer peripheral face of the middle portion of the screw and serves as a screwing end, and a matching groove is arranged between the screwing end and the thread. According to the scheme, the ball head bolt is wide in application range.

Description

Ball stud

Technical field

The utility model relates to a kind of bolt, is specifically related to a kind of ball stud.

Background technique

Nowadays, progress and development along with industry, plain bolt generally has been applied to each technical field, common bolt is mainly used in being fastenedly connected two with the part of through hole, yet because growing industrial technology, traditional bolt can't satisfy current needed function and degree easy to use, particularly in automobile industry, need the ball-and-socket of bolt and bearing sheath body to constitute ball-and-socket joint.

Summary of the invention

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ball stud applied widely.

For achieving the above object, the utility model provides following technological scheme: comprise screw rod, it is characterized in that: an end of described screw rod is provided with spherical pieces, described spherical pieces is provided with the mountion plate perpendicular with screw axial away from an end of screw rod, the other end outer circumferential face of described screw rod is provided with screw thread, it is that orthohexagonal convex tendon conduct screws end that described screw rod middle part outer circumferential face is provided with side face, and described screwing between end and the screw thread is provided with fit.

By adopting technique scheme, spherical pieces can constitute ball-and-socket joint with the ball-and-socket of bearing sheath body, and the screw thread of the other end makes ball stud can lock other tapped hole, make the bulb screw thread have simultaneously this two kinds of functions, applied widely, it is convenient when the setting of mountion plate is installed the ball-and-socket of bulb piece and bearing sheath body, can not be subject to too large resistance, screwing end cooperates spanner can make more easily thread lock in other tapped hole, also the locking degree of depth in double thread hole limits, make installation more stable, fit makes thread lock can not be subject to the obstruction of screw rod in other tapped hole.

The utility model further is set to: the area of described mountion plate is less than the area of the maximum cross section of spherical pieces.

By adopting technique scheme, the area of mountion plate is less than both making spherical pieces be difficult for deviating from the ball-and-socket of bearing sheath body, and convenient when the ball-and-socket that makes bulb piece and bearing sheath body is installed, can not be subject to too large resistance, wherein when the area of mountion plate be that the area two/a period of time effect of maximum cross section is best.

The utility model further is set to: the spherical pieces on described screw rod and the screw rod, screw end and all make by No. 35 carbon constructional quality steels.

By adopting technique scheme, No. 35 carbon constructional quality steel has good plasticity and suitable intensity, technology capability is better, welding performance still can, be fit to very much the usage requirement of ball stud, and No. 35 carbon constructional quality steel uses 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 ball stud, comprise screw rod 1, one end of screw rod 1 is provided with spherical pieces 2, spherical pieces 2 is provided with and screw rod 1 axial perpendicular mountion plate 21 away from an end of screw rod, the other end outer circumferential face of screw rod 2 is provided with screw thread 5, it is that orthohexagonal convex tendon is as screwing end 3 that screw rod 1 middle part outer circumferential face is provided with side face, described screwing between end 3 and the screw thread 5 is provided with fit 4, spherical pieces 2 can constitute ball-and-socket joint with the ball-and-socket of bearing sheath body, and the screw thread 5 of the other end makes ball stud can lock other tapped hole, make the bulb screw thread have simultaneously this two kinds of functions, applied widely, it is convenient when the setting of mountion plate 21 makes bulb piece 2 install with the ball-and-socket of bearing sheath body, can not be subject to too large resistance, screwing end 3 cooperates spanner can make more easily thread lock in other tapped hole, also the locking degree of depth in double thread hole limits, make installation more stable, fit 4 makes thread lock can not be subject to the obstruction of screw rod in other tapped hole, the area of mountion plate 21 is less than the area of the maximum cross section of spherical pieces 2, the area of mountion plate 21 is less than both making spherical pieces 2 be difficult for deviating from the ball-and-socket of bearing sheath body, and convenient when bulb piece 2 is installed with the ball-and-socket of bearing sheath body, can not be subject to too large resistance, wherein when the area of mountion plate 21 be that the area two/a period of time effect of maximum cross section is best, spherical pieces 2 on screw rod 1 and the screw rod 1, screwing end 3 all makes by No. 35 carbon constructional quality steels, No. 35 carbon constructional quality steel has good plasticity and suitable intensity, technology capability is better, welding performance still can, be fit to very much the usage requirement of ball stud, and No. 35 carbon constructional quality steel uses extensively, be easy to buying and processing, bring very big facility to production.
