Connecting structure used between objects

Abstract

The utility model discloses a connecting structure used between objects, which comprises at least two objects to be connected, the surfaces of the objects are provided with mounting holes, the objects are connected through flange bolts, spacer bushes and nuts, the flange bolts sequentially penetrate through the objects, the spacer bushes and the nuts, one end of each threaded sleeve is connected with the corresponding nut, and the other end of each threaded sleeve is connected with the bottom surface of the corresponding object. By the adoption of the flange face bolts, the spacer bushes and the flange nuts, objects can be firmly and stably installed. And the long bolt has better flexibility. And when various impact vibrations exist, the whole structure has better shockproof and anti-loosening effects and is more fatigue-resistant. Compared with a common bolt, the flange bolt has larger torque, so that objects are connected more firmly, and the flange bolt is suitable for thin objects through the spacer bush.

Description

Technical Field

[0001] The utility model relates to a connection structure used between objects. Background Art

[0002] When fastening the plates together, bolts plus flat washers, spring washers, nuts, or bolts plus flange locking nuts are generally used. The distance between the bolts and nuts is close, and the flexibility of the bolts is low. For example, in an environment with high strength requirements and frequent vibrations, the nuts are easily loosened and the bolts are fatigued and fractured. Therefore, when stronger fixation is required, flange bolts with greater torque are used. However, flange bolts are long bolts, and after the screw passes through the object, a long section of the screw is exposed, which is time-consuming and labor-intensive to tighten the nut. In addition, the upper section of the screw of most flange nuts is a smooth, threadless cylindrical structure, and the nut cannot be tightened. Therefore, it is not suitable for connections between thinner objects. Utility Model Content

[0003] The purpose of the utility model is to solve the above deficiencies in the prior art and provide a connection structure between objects.

[0004] A connection structure between objects includes at least two objects to be connected. The surfaces of the objects are provided with mounting holes. The objects are connected by flange bolts, spacers, and nuts. The flange bolts pass through the objects, spacers, and nuts in sequence. One end of the spacer is connected to the nut, and the other end is connected to the bottom surface of the object.

[0005] In order to ensure the fit between the spacer and the screw part of the flange bolt, the flange bolt includes a head and a screw, the bottom surface of the head is connected to one end of the screw, a gasket integrated with the head is provided at the connection between the head and the screw, the upper section of the screw is a smooth cylindrical structure, and the lower section of the screw is a cylindrical structure with threads.

[0006] In order to increase the force-bearing area and reduce the damage caused by excessive stress and torque, the nut is a flange nut.

[0007] Beneficial effects: Compared with the prior art, the utility model adopts flange bolts, spacers, and flange nuts to make the installation between objects firm and stable. Long bolts have better flexibility. When there are various impact vibrations, the entire structure has better shock and loosening resistance and is more resistant to fatigue. Flange bolts have greater torque than ordinary bolts, so the connection between objects is more secure, and the spacers make flange bolts suitable for thinner objects.
