Description

Stud bolt

Technical Field

The utility model belongs to the mechanical equipment field, concretely relates to stud.

Background

At present, stud is used widely in the field of mechanical equipment, and stud cooperation nut is applicable to ordinary fastener and connects usually, has preset the bolt hole on the work piece, and stud's one end and bolt hole cooperation are connected, however, sometimes the work piece structure is too light or the hole of presetting on the work piece is unsatisfactory, only depends on the connecting hole on the work piece and stud's bolted connection, can't realize fastening connection, consequently, need to propose a new stud and solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the utility model provides a be equipped with the locating part in stud's one end, aim at solving among the relevant art stud and can't realize fastening connection's technical problem.

The utility model adopts the technical scheme as follows:

the utility model provides a stud, includes screw rod, cylinder axle and limiting plate, screw rod one end coaxial line is connected with the cylinder axle is equipped with the groove on the cylinder axle terminal surface, groove and external intercommunication are connected with rotatable on the groove lateral wall the limiting plate.

Preferably, a support column is inserted into the limit plate, two ends of the support column are respectively and fixedly arranged on two opposite side walls of the groove, and the limit plate is rotatably connected with the support column.

Preferably, a wrench groove is formed in the end face of one end, far away from the cylindrical shaft, of the screw rod; the screw rod is internally provided with a through hole, the upper part of the through hole is communicated with the groove, and the lower part of the through hole is communicated with the wrench groove.

Preferably, both ends of the limiting plate are arranged to be in a round angle structure.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, it is rotatable to be connected with on the groove lateral wall limiting plate, limiting plate can carry out spacing cooperation to the work piece from the one end of work piece and establish the nut at the other end of work piece and carry out fastening connection to the work piece.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

With reference to figures 1-4 of the drawings,

the utility model provides a stud, includes screw rod 1, cylinder axle 2 and limiting

plate

3, and 1 one end coaxial line of screw rod is connected with cylinder axle 2, is equipped with groove 4 on the 2 terminal surfaces of cylinder axle, and groove 4 communicates with the external world, is connected with rotatable limiting plate 3 on the 4 lateral walls in groove.

The limiting plate 3 is inserted with a supporting column 5, two ends of the supporting column 5 are respectively and fixedly arranged on two opposite side walls of the groove 4, and the limiting plate 3 is rotatably connected with the supporting column 5.

A wrench groove 6 is arranged on the end surface of one end of the screw rod 1 far away from the cylindrical shaft 2; the screw rod 1 is internally provided with a through hole, the upper part of the through hole 7 is communicated with the groove 4, and the lower part of the through hole is communicated with the wrench groove 6.

Both ends of the limiting plate 3 are arranged into a fillet structure.

The working principle of the utility model is as shown in fig. 4, when the stud bolt is fixed on the workpiece 8, the limiting plate 3 is adjusted to be coaxial with the screw rod 1, one end of the stud bolt close to the limiting plate 3 is inserted into the preset hole on the workpiece 8, and the groove 4 is inserted into the preset hole and is far away from one end of the wrench groove 6; if a gap exists between the preset hole and the outer diameter of the stud bolt, the stud bolt can be shaken to enable the limiting plate 3 to rotate to the horizontal position to limit the upper end of the stud bolt, and then the stud bolt is matched with a nut 9 arranged on one side, far away from the limiting plate 3, of the workpiece 8 to fasten the workpiece 8; if 1 chucking of screw rod is predetermineeing downthehole unable rocking, inserts the pin in through-hole 7, the pin touches the rotation in limiting plate 3 bottoms for limiting plate 3 rotates horizontal position and carries on spacingly to the stud upper end, then the cooperation is established and is kept away from nut 9 of nearly limiting plate 3 one side at work piece 8 and fasten work piece 8.

The both ends of limiting plate 3 set to fillet structure, make things convenient for the slender rod to touch the rotation in limiting plate 3 bottom.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
