Detailed Description

The following disclosure provides many different embodiments or examples for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

The fastener is used as a mechanical basic part for fastening connection, and the fastener has wide application industries including energy, electronics, electrical appliances, machinery, chemical engineering, metallurgy, dies, hydraulic pressure and the like. On new energy vehicles, fasteners are often used in conjunction with bushings to effect the connection of the sheet metal cover and the bottom shell. However, in the actual use process, the bushing is easy to fall off from the fastener, and certain potential safety hazards exist. In order to improve the reliability of bush and bolted connection, the technical scheme of this application provides metal sheet insert bush bolt sub-assembly. The technical scheme is as follows:

the present application is described in further detail below with reference to fig. 1-5.

As shown in fig. 1 and 2, the application provides a metal plate insert bushing bolt assembly, which comprises a bolt body 1 and a bushing 2, wherein the bolt body 1 comprises a bolt head 3 and a stud 4 which are coaxially fixedly connected, the bushing 2 is slidably sleeved on the stud 4, a radial gap is arranged between the bushing 2 and the stud 4, and a riveting structure 5 is arranged at one end, far away from the bolt head 3, of the bushing 2.

As shown in fig. 2, the outer wall of the stud 4 close to the bolt head 3 is provided with a smooth section 41, and the outer wall of the stud 4 far from the bolt head 3 is provided with a threaded section 42. The anti-dropping part is fixedly sleeved on the stud 4 and is an anti-dropping ring 6, the anti-dropping ring 6 and the stud 4 are integrally formed, and the anti-dropping ring is positioned at the junction of the threaded section 42 of the smooth section 41. The inner wall of the bush 2 is provided with a blocking part, and the anti-drop ring 6 and the blocking part form interference fit.

Referring to fig. 2 and 3, in the present embodiment, the blocking portion is a straight wall section 7, and the straight wall section 7 is integrally formed with the inner wall of the liner 2. In a specific implementation, the blocking portion may also be a convex point 8, and the convex point 8 is formed by recessing the bushing 2 towards the center line of the bushing 2.

During the actual use, earlier be connected bush 2 through riveted structure 5 and panel beating shroud, then, be connected stud 4 and bottom casing, realized being connected of panel beating shroud and bottom casing. At this moment, because the anti-drop ring 6 is in interference fit with the blocking part, the lining 2 is limited, the possibility that the lining 2 drops from the fastener is reduced, and the stability and the reliability of connection are improved.

As shown in fig. 1 and 2, in order to further improve the retaining effect of the bush 2, a retaining knurl 9 is formed on the outer wall of the retaining ring 6, and the retaining knurl 9 is a straight knurl. In addition, the end face of the anti-drop ring 6, which is far away from the bolt head 3, is a conical surface, so that an operator can conveniently sleeve the bushing 2 on the bolt body 1 before installation.

As shown in fig. 2, the riveting structure 5 includes a riveting ring 10 coaxially connected to the bushing 2, in this embodiment, a solid knurl 11 and a groove 12 are provided on the riveting ring 10, and an end surface of the riveting ring 10 far away from the bushing 2 is in a flanging shape.

Referring to fig. 4 and 5, in a specific implementation, the riveting structure 5 can also be a riveting ring 10 provided with a solid knurling 11 or a riveting ring 10 provided with a groove 12.

The specific implementation principle of the application is as follows: during the actual use, earlier be connected bush 2 through riveted structure 5 and panel beating shroud, then, be connected stud 4 and bottom casing, realized being connected of panel beating shroud and bottom casing. At this moment, because the anti-drop ring 6 is in interference fit with the blocking part, the lining 2 is limited, the possibility that the lining 2 drops from the fastener is reduced, and the stability and the reliability of connection are improved. Meanwhile, the radial clearance between the bush 2 and the stud 4 can eliminate the positioning error caused by the processing of the sheet metal cover cap and the bottom shell, and further improves the connection reliability.
