Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile rust-proof bolt. Background Art

[0002] A car is made up of multiple parts and components. When connecting these parts, some of them need to use bolt assemblies. Bolts are mechanical parts. Bolts are a type of fastener consisting of a head and a screw (a cylinder with external threads). They need to be used with nuts to fasten and connect two parts with through holes. Bolts are the most used parts in cars, so bolts are particularly important for the safety of cars.

[0003] Existing automobile bolts have nuts screwed onto the screw rods after installation. As the car vibrates when driving on the road, this vibration is transmitted to the bolt, which may cause the nut to move slightly. As the car travels longer and longer mileage, the bolt and nut may become loose. Utility Model Content

[0023] In order to enable the connection plate 3 to be sleeved on the bolt body 1 , a movable hole 11 is opened in the middle of the connection plate 3 , and the upper end of the surface of the bolt body 1 is movably sleeved in the movable hole 11 .

[0024] In order to fix the connecting plate 3 on the bolt body 1 so that the connecting plate 3 cannot move up and down, the connecting assembly 5 includes a connecting block 51, the top surface and the bottom surface of the connecting block 51 are fixedly connected to the top surface and the bottom surface of the connecting groove 4 respectively, and the connecting block 51 is arranged between the bolt body 1 and the fixing rod 8. The middle part of the connecting block 51 is movably sleeved with a first plug rod 52, and one end of the first plug rod 52 close to the bolt body 1 is movably sleeved on a side of the connecting groove 4 close to the bolt body 1 and is inserted into the adjacent first socket 6.

[0025] In order to facilitate the removal of the first insertion rod 52 from the first insertion hole 6, the end face of the first insertion rod 52 away from the bolt body 1 is fixedly connected to a push block 53, and the front face of the push block 53 is fixedly connected to a toggle rod 54. Movable openings 12 are provided on the left and right sides of the front face of the connecting plate 3. The two movable openings 12 are respectively connected to the adjacent connecting grooves 4. The front end of the toggle rod 54 is movably sleeved in the adjacent movable openings 12 and penetrates to the outside of the front side of the connecting plate 3.

[0026] In order to fix the protective sleeve 7 and prevent the protective sleeve 7 from moving upward, the fixing assembly 9 includes a second plug rod 91, which is movably sleeved inside the connecting groove 4, and the end of the second plug rod 91 away from the bolt body 1 is movably sleeved on the side wall of the connecting plate 3 and penetrates to the outside of the connecting plate 3, and the end face of the second plug rod 91 away from the bolt body 1 is fixedly connected with a pull ring 92, and the second plug rod 91 is adapted to the second plug hole 10, and a fixing block 93 is fixedly sleeved on the surface of the second plug rod 91 near the middle of the bolt body 1, and a spring 94 is sleeved on the surface of the second plug rod 91, one end of the spring 94 is fixedly connected to the fixing block 93, and the other end of the spring 94 is fixedly connected to the side of the side wall of the connecting groove 4 away from the bolt body 1, and the end face of the second plug rod 91 away from the pull ring 92 conflicts with the side of the adjacent push block 53 away from the bolt body 1.

[0027] In order to enable the upper end of the bolt body 1 to pass through the upper end of the protective sleeve 7, a through hole 13 is opened at the top of the protective sleeve 7. The upper end of the bolt body 1 is movably sleeved in the through hole 13 and passes through to the outside of the top of the protective sleeve 7. A sealing rubber ring is fixedly connected to the bottom surface of the protective sleeve 7 and the through hole 13. The sealing rubber ring can improve the sealing performance of the protective sleeve 7.

[0028] In order to enable the fixing rod 8 to be inserted into the connecting groove 4, plug openings 14 are provided on the left and right sides of the top surface of the connecting plate 3. The two plug openings 14 are respectively connected to the two connecting grooves 4, and the lower ends of the two fixing rods 8 are respectively plugged into adjacent plug openings 14.

[0029] Working principle: When the utility model is used, first pull the two pull rings 92 to move the second plug rod 91 toward the outside, then push the two push rods 54 to make the two first plug rods 52 move away from each other and move out of the movable hole 11, then the connecting plate 3 is sleeved on the upper end of the bolt body 1 through the movable hole 11, and the pull ring 92 is released. Since the second plug rod 91 moves toward the outside, it will drive the fixing block 93 to move, so that the fixing block 93 squeezes the spring 94. At this time, the pulled pull ring 92 is released, and the restoring force of the spring 94 will push the fixing block 93 to move toward the fixing rod 8. The fixing block 93 drives the second plug rod 91 to move toward the fixing rod 8, so that the end surface of the fixing rod 8 contacts the push block 53, and pushes the first plug rod 52 into the first insertion hole 6, thereby fixing the connecting plate 3 on the bolt body 1. The first plug rod 52 cannot move out of the first insertion hole 6 by itself due to the elastic potential energy of the spring 94. Then the nut 2 is threadedly sleeved on the upper end of the bolt body 1, so that The bottom surface of the nut 2 fits with the top surface of the connecting plate 3, and then the protective sleeve 7 is sleeved on the upper end of the bolt body 1, so that the lower end of the fixing rod 8 is inserted into the plug-in opening 14, and then the two pull rings 92 are pulled downward again, and the protective sleeve 7 is pressed downward, and the protective sleeve 7 drives the fixing rod 8 to descend until the bottom surface of the fixing rod 8 fits with the bottom surface of the connecting groove 4, and then the pulled pull ring 92 is released, and the restoring force of the spring 94 makes the second insertion rod 91 move toward the fixing rod 8 and insert it into the second insertion hole 10, fixing the fixing rod 8 so that the protective sleeve 7 cannot move upward. At this time, the top surface of the inner cavity of the protective sleeve 7 fits with the top surface of the nut 2, so that the nut 2 can no longer move up and down on the surface of the bolt body 1, and prevents the bolt body 1 and the nut 2 from loosening due to vibration. At the same time, the nut 2 is sleeved in the protective sleeve 7, so that the nut 2 is isolated from the external environment, and the nut 2 is prevented from being rusted and corroded due to being exposed to the external environment for a long time.

[0030] The technical features of the above embodiments may be combined arbitrarily. 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.

[0031] 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.
