Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flange nuts, in particular to a flange nut for an automobile chassis. Background Art
[0002] A flange nut is a nut that has a wide flange on one end that acts as an integrated washer. This serves to distribute the pressure of the nut across the component being secured, reducing the likelihood of component damage and making it less likely to loosen due to an uneven fastening surface. These nuts are mostly hexagonal in shape, made from hardened steel, and are usually zinc plated. Flange nuts are often used to secure components to the chassis of an automobile in order to reduce the risk of the nut spinning loose during the securing process.
[0003] In the application scenarios of flange nuts, there is a problem that water and dust penetrate into the joint between the nut and the stud, which in turn causes the nut to rust. In order to meet this challenge, the traditional approach is to install a protective cover on the outside of the nut to isolate it from moisture and impurities in the external environment. However, this method faces a significant defect in actual application: the protective cover is simply put on the nut, and the fixing effect is general. When the car is driving, due to uneven road conditions or the vibration of the vehicle itself, the protective cover may loosen and detach from the nut, thereby losing its due protective effect.

[0020] In one embodiment, Figure 1-4 As shown, a car chassis flange nut comprises a nut body 1, a protective cover 2 is movably sleeved on the upper end of the surface of the nut body 1, support blocks 3 are fixedly connected to the left and right sides of the top surface of the nut body 1, the top surfaces of the two support blocks 3 are respectively fitted with the left and right sides of the top surface of the inner wall of the protective cover 2, slots 4 are provided on the facing surfaces of the two support blocks 3 and near the bottom, connecting blocks 5 are fixedly connected to the left and right sides of the top surface of the inner wall of the protective cover 2, the two connecting blocks 5 are located between the two supporting blocks 3, and the bottom surfaces of the two connecting blocks 5 are fixedly connected to fixing components 6.
[0021] In order to fix the protective cover 2 and prevent the protective cover 2 from falling off the nut body 1, the fixing component 6 includes a connecting sleeve 61, the top surface of the connecting sleeve 61 is fixedly connected to the bottom surface of the connecting block 5, the side of the connecting sleeve 61 close to the support block 3 is movably sleeved with an insert block 62, the side of the insert block 62 away from the support block 3 penetrates into the inner cavity of the connecting sleeve 61, the side of the insert block 62 close to the support block 3 is inserted into the adjacent slot 4, the side of the insert block 62 away from the support block 3 is fixedly connected with a spring 63, and one end of the spring 63 is fixedly connected to the side of the inner wall of the connecting sleeve 61 away from the support block 3.
[0022] In order to facilitate the operation of moving the plug block 62 toward the inside of the connecting sleeve 61, so that the protective cover 2 can be removed from the nut body 1, a first connecting rod 64 is fixedly connected to the side of the plug block 62 away from the support block 3, and a spring 63 is sleeved on the surface of the first connecting rod 64 close to one end of the plug block 62. The end of the first connecting rod 64 away from the plug block 62 is movably sleeved on the side of the connecting sleeve 61 away from the support block 3 and passes through the outside of the connecting sleeve 61. The end of the first connecting rod 64 away from the plug block 62 is hinged with a second connecting rod 65. A through hole is opened at the top of the protective cover 2, and a push rod 66 is movably sleeved in the through hole. The lower end of the push rod 66 passes through the inner cavity of the protective cover 2, and the bottom surface of the push rod 66 is fixedly connected to the third connecting rod 67. The bottom surface of the third connecting rod 67 is fixedly connected to the end of the second connecting rod 65 away from the first connecting rod 64.
[0023] In order to block the through hole on the protective cover 2 and prevent dust and water from entering the protective cover 2 through the through hole, a sealing sleeve 68 is fixedly sleeved on the outer surface of the push rod 66, and the sealing sleeve 68 is movably sleeved in the through hole.
[0024] In order to prevent the plug block 62 from moving too much and completely entering into the connecting sleeve 61, or completely detaching from the connecting sleeve 61, the top and bottom surfaces of the inner wall of the connecting sleeve 61 are provided with sliding grooves 69, and the top and bottom surfaces of the plug block 62 and the side away from the support block 3 are fixedly connected with sliders 610, and the two sliders 610 are slidably connected in adjacent sliding grooves 69 on the side away from the plug block 62.
[0025] In order to increase the sealing effect between the nut body 1 and the automobile parts, a sealing gasket 7 is fixedly connected to the middle of the bottom surface of the nut body 1, and the outer surfaces of the nut body 1 and the protective cover 2 are coated with epoxy resin waterproof coating.
[0026] Working principle: When the utility model is used, first press the push rod 66 downward, the push rod 66 drives the third connecting rod 67 to descend, the third connecting rod 67 pushes the end of the second connecting rod 65 away from the first connecting rod 64 to move downward, and the end of the second connecting rod 65 close to the first connecting rod 64 moves in the direction away from the connecting sleeve 61, the second connecting rod 65 will pull the first connecting rod 64, the first connecting rod 64 pulls the plug block 62, so that the plug block 62 moves toward the inside of the connecting sleeve 61, and then the protective cover 2 is sleeved on the upper end of the nut body 1 until the top surface of the support block 3 fits with the top surface of the inner wall of the protective cover 2. The two plug blocks 62 are aligned with the slots 4 of the two support blocks 3 respectively, and then the push rod 66 is pulled upward, and the spring 63 pushes the plug block 62 to move toward the outside of the connecting sleeve 61, so that the plug block 62 is inserted into the slot 4 on the support block 3, so that the connecting sleeve 61 cannot move upward. Since the connecting sleeve 61 is connected to the protective cover 2 through the connecting block 5, the protective cover 2 cannot move upward, so that the protective cover 2 is sleeved on the nut body 1 and cannot move, avoiding the problem that the protective cover 2 may loosen and detach from the nut body due to uneven road surface or vibration of the vehicle itself when the car is driving, thereby losing its due protective function.
[0027] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
