Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a new energy bolt with a locking screw hole. Background Technology

[0002] Fasteners, also known as standard parts in the market, are mechanical components that can mechanically fix or bond two or more parts together. They are characterized by a wide variety of types and specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used basic mechanical components, with a large demand. New energy bolts are one type of fastener.

[0003] Existing new energy bolts use a sealing ring at the nut to lock the bolt hole, thus preventing water from entering and corroding the bolt hole or the bolt body. However, current new energy bolts (bolts installed on new energy vehicles) can loosen as the vehicle moves and vibrates, causing the nut to fail to tighten the sealing ring. Utility Model Content

[0004] In view of the problems existing in a new energy bolt with a locking screw hole, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a new energy bolt with a locking screw hole, which solves the problem of existing new energy bolts that lock the screw hole by setting a sealing ring at the nut, thereby preventing water from entering the screw hole and corroding the screw hole or the bolt body; however, current new energy bolts (bolts installed on new energy vehicles) may loosen due to the movement of the vehicle, resulting in the bolt nut not being able to tighten the sealing ring.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A new energy bolt with a locking screw hole includes a bolt body, an integrally formed nut at the end of the bolt body, a first sealing ring fitted on the bolt body, a through hole on the bolt body, a support block welded to the center of the through hole, a locking structure installed on the support block, and a second sealing ring fitted on the bolt body.

[0008] As a preferred embodiment of the new energy bolt with locking screw hole described in this utility model, the locking structure includes a first spring welded to the support block, a first limiting locking block welded to the end of the first spring away from the support block, and the first limiting locking block being slidably connected to the inner wall of the through hole.

[0009] As a preferred embodiment of the new energy bolt with locking screw hole described in this utility model, the locking structure further includes a second spring welded to the support block, and a second limiting locking block is welded to the end of the second spring away from the support block. The second limiting locking block is slidably connected to the inner wall of the through hole.

[0010] As a preferred embodiment of the new energy bolt with locking screw hole described in this utility model, a metal gasket is bonded to the bottom of the second sealing ring.

[0011] As a preferred embodiment of the new energy bolt with locking screw hole described in this utility model, the bolt body is provided with a window, the window is connected to the through hole, and the support block is located inside the window.

[0012] Compared with existing technologies:

[0013] By setting a through hole on the bolt body and setting a locking structure inside the through hole, when the bolt body passes through two workpieces, the first limiting locking block and the second limiting locking block in the locking structure are located below the workpieces, thereby limiting the bolt body from loosening and ensuring that the first sealing ring and the second sealing ring are locked to the screw hole.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] This utility model provides a new energy bolt with a locking screw hole. Please refer to [link / reference]. Figure 1-4The device includes a bolt body 1, with a nut 2 integrally formed at the end of the bolt body 1. A first sealing ring 3 is fitted on the bolt body 1. A through hole 12 is formed on the bolt body 1. A support block 7 is welded to the center of the through hole 12. A locking structure is installed on the support block 7. A second sealing ring 4 is fitted on the bolt body 1. A metal gasket 5 is adhered to the bottom of the second sealing ring 4. The metal gasket 5 supports the second sealing ring 4 to ensure that the second sealing ring 4 fits tightly with the workpiece. A window 6 is formed on the bolt body 1. The window 6 communicates with the through hole 12. The support block 7 is located inside the window 6. The support block 7 can be welded to the bolt body 1 through the window 6.

[0021] The locking structure includes a first spring 8 welded to the support block 7, and a first limiting locking block 10 welded to the end of the first spring 8 away from the support block 7. The first limiting locking block 10 is slidably connected to the inner wall of the through hole 12.

[0022] The locking structure also includes a second spring 9 welded to the support block 7. A second limiting locking block 11 is welded to one end of the second spring 9 away from the support block 7. The second limiting locking block 11 is slidably connected to the inner wall of the through hole 12. The ends of the first limiting locking block 10 and the second limiting locking block 11 are both arc-shaped, so that during the process of the bolt entering the workpiece, the first limiting locking block 10 and the second limiting locking block 11 can automatically enter the through hole 12 under the reaction force of the workpiece.

[0023] In practical use, when the bolt body 1 passes through two workpieces to be fastened, the first limiting locking block 10 and the second limiting locking block 11 are squeezed by the workpieces and enter the through hole 12. At the same time, the first spring 8 and the second spring 9 are compressed. When the bolt body 1 has completely passed through the two workpieces, the second sealing ring 4 and the metal gasket 5 are put on the bolt body 1 from the bottom. At this time, the second sealing ring 4 and the metal gasket 5 are located below the workpieces and above the first limiting locking block 10 and the second limiting locking block 11. The first sealing ring 3 and the second sealing ring 4 are squeezed, and the first sealing ring 3 and the second sealing ring 4 achieve the sealing and locking of the screw hole.

[0024] Under the limiting action of the first limiting locking block 10 and the second limiting locking block 11, the bolt body 1 is prevented from loosening and moving up and down, ensuring the stable and effective locking of the screw hole.

[0025] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
