Wherein, 1, a boss; 2. a bushing; 3. a screw; 4. binding the tail of the bolt; 5. a first flange; 6. a gasket; 7. a bolt head; 8. a second flange; 9. a threaded rod.
Detailed Description
In order to achieve the above objects, features and advantages of the present invention and to make the same more comprehensible, the present invention is described in detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and fig. 2, the present embodiment provides a bushing bolt, which includes a bolt head 7, a boss 1 is disposed at one end of the bolt head 7, a screw 3 extends from one end of the boss 1 facing away from the bolt head 7, a threaded rod 9 extends from one end of the screw 3 facing away from the boss 1, a cross-sectional area of the threaded rod 9 is greater than a cross-sectional area of the screw 3, a bushing 2 is sleeved on the screw 3, the bushing 2 includes a first flange 5 and a second flange 8, a cross-sectional area of the first flange 5 is greater than a cross-sectional area of the second flange 8, and a washer 6 is sleeved on the bushing 2.
Furthermore, the surface of the screw rod 3 is smooth, the bushing 2 is in sliding connection with the screw rod 3, and because the cross section area of the threaded rod 9 is larger than that of the screw rod 3, when the bushing 2 slides downwards, the first flange 5 is abutted to one end, close to the screw rod 3, of the threaded rod 9, so that the bushing 2 can only slide on the screw rod 3, and the bushing 2 is prevented from falling off from the screw rod 3.
Further, the bolt head 7, the screw rod 3 and the threaded rod 9 are all made of steel, aluminum or copper materials.
Further, the gasket 6 is made of rubber or other elastic materials.
Further, the bolt head 7, the screw rod 3 and the threaded rod 9 are coaxial.
Further, the outer surface of the threaded rod 9 is provided with threads, one end of the threaded rod 9, which is far away from the threaded rod 3, is provided with a thread beam tail 4, and the cross-sectional area of the thread beam tail 4 is smaller than that of the threaded rod 9.
Further, the cross-sectional area of the boss 1 is larger than the cross-sectional area of the bolt head 7, and the cross-sectional area of the boss 1 is smaller than the cross-sectional area of the first flange 5.
Further, both ends of the threaded rod 9 are provided with chamfers.
During the use, with bush 2 cover at screw rod 3, receive strong effort when owing to bush 2 installation, less deformation can take place for first flange 5, makes first flange 5 can pass threaded rod 9 cover at screw rod 3, then first flange 5 resumes original state. The bush 2 slides from top to bottom at the screw rod 3, and the top of 2 sliding position of bush is that the up end of first flange 5 is inconsistent with boss 1, and the bottom of 2 sliding position of bush is that the lower terminal surface that first flange 5 is close to screw rod 3 is inconsistent with the upper end of threaded rod 9, because the cross-sectional area of threaded rod 9 is greater than the cross-sectional area of screw rod 3 for bush 2 can only slide on screw rod 3, is difficult to drop from screw rod 3.
After the installation, the bush 2 is sleeved with the gasket 6, and the cross-sectional area of the first flange 5 is larger than that of the second flange 8, so that even if the gasket 6 is greatly deformed, the gasket 6 can be abutted against the first flange 5, and the gasket 6 is prevented from falling off from the bush 2. The workpiece is installed between the gasket 6 and the second flange 8, one end of the workpiece is in contact with the gasket 6, the other end of the workpiece is in contact with the second flange 8, and when the workpiece vibrates and shakes, the gasket 6 has a buffering effect, so that the effects of vibration prevention, noise reduction and the like are achieved.
The scope of the present invention is not limited to the above embodiments, and any modifications, equivalent substitutions, improvements, etc. that can be made by those skilled in the art within the spirit and principle of the inventive concept should be included in the scope of the present invention.
