Description

Technical Field

[0001] The utility model relates to the technical field related to bolt connection, in particular to a flexible bolt connection structure. Background Art

[0002] Bolt is a general term for fasteners. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be used in conjunction with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, the bolt connection is a detachable connection.

[0003] However, most of the current bolt connection methods are in direct rigid contact with the installation workpiece, so the bolts will cause compressive damage to the installation workpiece, reduce the stability of the installation workpiece, and cannot flexibly absorb the vibration force at the connection between the installation workpiece and the bolt, and the stability of the actual connection operation is not ideal.

[0006] As a further preferred embodiment of the present technical solution, the flexible mechanism includes a circular plate No. 1 and a circular plate No. 2, and the circular plate No. 1 is distributed in parallel with the circular plate No. 2. A cross-shaped groove is concave inwardly on the circular plate No. 1, and a cross-shaped piece is protruded outwardly on the circular plate No. 2, and the cross-shaped piece is correspondingly engaged with the cross-shaped groove to engage the circular plate No. 1 with the circular plate No. 2, and a plurality of flexible pieces are hidden and distributed in the cross-shaped groove, so that the flexibility between the circular plate No. 1 and the circular plate No. 2 is improved by the flexible pieces.

[0007] As a further preferred embodiment of the present technical solution, the flexible part includes a buffer plate slidably installed at each edge of the cross-shaped groove, and a slideway cooperating with the buffer plate is opened in the cross-shaped groove, and a plurality of buffer springs are installed between the buffer plate and the bottom of the cross-shaped groove, and the flexibility between the No. 1 circular plate and the No. 2 circular plate is limited by the buffer plate and the buffer spring.

[0008] As a further preferred embodiment of the present technical solution, a No. 1 anti-skid pad is installed on the lower surface of the No. 1 circular plate, and a No. 2 anti-skid pad is installed on the upper surface of the No. 2 circular plate.

[0009] As a further preferred embodiment of the present technical solution, the No. 1 circular plate and the No. 2 circular plate are arranged in cooperation with the bolts, and through holes cooperating with the bolts are penetrated through the No. 1 circular plate and the No. 2 circular plate.

[0010] As a further preferred embodiment of the present technical solution, the bolt and the nut are arranged in cooperation with each other, and the position of the flexible mechanism can be limited by the bolt and the nut.

[0011] The utility model provides a flexible bolt connection structure, which has the following beneficial effects:

[0013] Since the cross-shaped piece can slide up and down in the cross-shaped groove and is flexibly limited by the buffer plate and the buffer spring, it can achieve flexible absorption of external vibration force. During use, it is only necessary to tighten the two flexible mechanisms with the corresponding loose nuts to limit the sliding amount of the flexible mechanisms, thereby limiting the deformation amount of the buffer spring and freely adjusting the flexibility. It can be adjusted and used for different installation workpieces and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
