Description

Anti-fracture connecting rod bolt

Technical Field

The utility model belongs to the technical field of bolt equipment, more specifically say, relate to an anti-fracture connecting rod bolt.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

As a further improvement, the fastening nut upper end is provided with the mounting groove, installs the bearing in the mounting groove, bearing inner wall and stiffener upper end fixed connection.

As a further improvement, the fastening nut is fixedly provided with a pressing plate, and the lower end surface of the pressing plate is matched with the upper end surface of the bearing to be offset to the position of the bearing.

As a further improvement, the reinforcing rod is a stud rod, the lower end of the reinforcing rod penetrates through a through hole in the fixing nut, and the reinforcing rod stretches out of one end of the fixing nut and is provided with a clamping nut.

Compared with the prior art, the utility model has the advantages of:

1. the utility model discloses a set up the through-hole on setting up spacing groove and fixation nut on the screw rod, the supporting power that the screw rod can be strengthened to the cooperation stiffener avoids appearing cracked condition.

2. The utility model discloses be provided with the bearing, can make things convenient for the rotation of stiffener through the bearing, avoid taking place the condition that fastening nut and stiffener interfered when rotating fastening nut.

3. The utility model discloses a set the stiffener to the screw pole, can stretch out fixation nut's one end installation at the stiffener and step up the nut, when playing the purpose that increases the support, the connection stability of reinforcing bolt that can step forward, when the screw rod fracture appears, through the stiffener with step up being connected of nut, also can realize bolted connection's purpose.
