Description

Technical Field

[0001] The utility model relates to a bolt, in particular to a riveted bolt connected in series with a copper bar. Background Art

[0002] Ordinary bolts are prone to slipping when connected in series with copper bars, the connection strength is not firm, and discharge is prone to occur at the connection. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides a riveted bolt connected in series with a copper busbar. The riveted connection method can achieve a firm connection between the stud and the copper busbar, improve the connection surface between the stud and the copper busbar, and prevent discharge from occurring on the connection surface.

[0004] The technical scheme of the utility model is: a riveted bolt connected in series with a copper bar, comprising a bolt head and a screw rod, wherein the root of the bolt head is connected with the bottom surface of the screw rod as a whole; and a circle of flower-shaped teeth is processed at the root of the screw rod.

[0005] Furthermore, the maximum outer diameter of the flower-shaped teeth is 4-6 mm larger than the maximum outer diameter of the screw body.

[0006] Furthermore, the flower-shaped teeth are formed by a plurality of blades evenly arranged along the circumference of the screw root.

[0007] Furthermore, the blade is an irregular trapezoid, the first side is a straight side and is connected to the root surface of the screw as a whole, the second side is a straight side perpendicular to the first side and is connected to the bottom surface of the bolt head as a whole, the third side is a straight side perpendicular to the second side and is shorter than the first side, the fourth side is an arcuate side with one end connected to the end of the third side and the other end connected to the end of the first side, and the angle formed between the fourth side and the third side is an obtuse angle, and the angle formed between the fourth side and the first side is an acute angle.

[0008] The beneficial effects of the utility model are as follows: compared with the existing structure, this bolt has a flower-shaped tooth added at the root, which is connected to the copper busbar by riveting, thereby increasing the connection area between the bolt and the copper busbar. After riveting, the torque of the stud can be increased, and there will be no slipping when the nut is tightened. The connection is firm so that no discharge will occur on the connection surface.

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] like Figure 2 As shown, a riveted bolt connected in series with a copper bar comprises a bolt head 1 and a screw rod 2, wherein the root of the bolt head 1 is connected to the bottom surface of the screw rod 2 as a whole. A circle of flower-shaped teeth 3 is processed at the root of the screw rod 2. The maximum outer diameter of the flower-shaped teeth 3 is 5 mm larger than the maximum outer diameter of the body of the screw rod 2. The flower-shaped teeth 3 are formed by a plurality of blades evenly arranged along the circumference of the root of the screw rod 2, and the blades are irregular quadrilaterals, the first side is a straight side and is connected to the root surface of the screw rod 2 as a whole, the second side is a straight side perpendicular to the first side and is connected to the bottom surface of the bolt head 1 as a whole, the third side is a straight side perpendicular to the second side and is shorter than the first side, and the fourth side is an arc-shaped side with one end connected to the end of the third side and the other end connected to the end of the first side, and the angle formed between the fourth side and the third side is an obtuse angle, and the angle formed between the fourth side and the first side is an acute angle.

[0016] This is Figure 2 The bolt shown in the figure has a flower-shaped tooth at the root, and is riveted to the bolt as shown in the figure. Figure 1 The copper busbar 4 shown is connected to form Figure 3 , 4 The structure shown in the figure increases the contact area between the bolt and the copper bar, and can increase the torque of the stud after riveting. There will be no slipping when the nut is tightened, and the connection is firm so that there will be no discharge on the contact surface.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
