Technical Field

[0001] The utility model relates to the technical field of vehicle lamp bolts, in particular to a vehicle lamp bolt with a sealing and compacting function. Background Art

[0002] Headlights serve as the light source of a car and provide illumination for the car in low-light environments. Headlights are often connected and fixed to the car using bolts.

[0003] The existing bolts have poor anti-loosening ability. During the use of the car, there will be high-frequency vibration, which may cause the bolts and nuts to loosen, thereby loosening the headlights and causing the sealing of the headlights to decrease.

[0004] Therefore, in order to solve the above problems, a headlight bolt with a sealing and compacting function can be designed, and an anti-loosening mechanism can be added to the bolt body to prevent the vibration of the car from causing the bolt body to rotate, thereby ensuring a tight connection between the headlight and the car. Utility Model Content

[0005] In order to overcome the poor anti-loosening ability of most bolts, there will be high-frequency vibration during the use of the car. This vibration may cause the bolts and nuts to loosen, thereby loosening the headlights and causing the sealing of the headlights to decrease.

[0006] The technical solution of the utility model is as follows: a headlight bolt with a sealing and compacting function comprises a bolt body, a soft layer, a fixing seat, a reinforcing wire, a limit strip, a spring, a push rod, a toothed disc and a hexagonal seat; a soft layer is provided on the outside of the bolt body, the soft layer is made of a soft hydrophobic material, a fixing seat is provided above the bolt body, a toothed disc is provided above the bolt body, the toothed disc is located on the inner side of the fixing seat and is rotatably connected to the fixing seat, a limit strip is provided on the inner side of the fixing seat, the limit strip is rotatably connected to the fixing seat, the limit strip and the toothed disc are meshed with each other, a spring is provided on one side of the limit strip, a push rod is provided on one side of the limit strip, the push rod is slidably connected to the fixing seat, a hexagonal seat is provided above the toothed disc, a reinforcing wire is provided on the inner side of the hexagonal seat, the reinforcing wire is slidably connected to the hexagonal seat, and the reinforcing wire is fixedly connected to the fixing seat.

The spring pushes the limit bar and the toothed disc to engage with each other for limiting, so that the toothed disc and the fixing seat can only rotate in one direction, preventing the bolt body from rotating in the opposite direction due to vibration after connection and causing loosening. The reinforcing wire can further fix the hexagonal seat to the fixing seat to prevent the bolt body from rotating. Pressing the push rod can push the limit bar compression spring to release the limit on the toothed disc.

[0008] Preferably, a reinforcement groove is provided above the hexagonal seat, and three groups of reinforcement grooves are provided, and the reinforcement grooves run through from one side of the hexagonal seat to the opposite side.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-4 The utility model provides an embodiment: a headlight bolt with a sealing and compacting function, comprising a bolt body 1, a soft layer 2, a fixing seat 3, a reinforcing wire 4, a limiting strip 5, a spring 6, a push rod 7, a toothed disc 8 and a hexagonal seat 9; a soft layer 2 is provided on the outside of the bolt body 1, and the soft layer 2 is made of a soft hydrophobic material. A fixing seat 3 is provided above the bolt body 1, and a toothed disc 8 is provided above the bolt body 1. The toothed disc 8 is located inside the fixing seat 3 and is rotatably connected to the fixing seat 3. A limiting strip 5 is provided on the inside of the fixing seat 3, and the limiting strip 5 is rotatably connected to the fixing seat 3. The limiting strip 5 and the toothed disc 8 are meshed with each other. A spring 6 is provided on one side of the limiting strip 5, and a push rod 7 is provided on one side of the limiting strip 5. The push rod 7 is slidably connected to the fixing seat 3, and a hexagonal seat 9 is provided above the toothed disc 8. A reinforcing wire 4 is provided on the inside of the hexagonal seat 9. The reinforcing wire 4 is slidably connected to the hexagonal seat 9, and the reinforcing wire 4 is fixedly connected to the fixing seat 3.

[0023] See also Figure 2 In this embodiment, a reinforcement groove 101 is provided above the hexagonal seat 9. There are three groups of reinforcement grooves 101, which extend from one side of the hexagonal seat 9 to the opposite side. The reinforcement groove 101 is used to engage with the reinforcement wire 4 to prevent the hexagonal seat 9 from rotating.

[0024] See also Figure 3When the bolt 302 is in the unlock position, the bolt 302 is locked and the locking nut 301 is unlocked, so the bolt 302 can be locked in the unlock position when the bolt 302 is locked.

[0025] See also Figure 4 In this embodiment, a rotating shaft 502 is provided on the upper and lower sides of the limit bar 5, and the rotating shaft 502 passes through the fixed seat 3 and is rotatably connected to the fixed seat 3. A limiting tooth 501 is provided on one side of the limit bar 5, and the limiting tooth 501 is consistent with the tooth inclination direction of the tooth plate 8. The spring 6 and the limiting tooth 501 are arranged on the same side, and a top block 701 is provided at one end of the push rod 7. A first limiting ring 702 is provided on the outside of the push rod 7, and the first limiting ring 702 is located on the inner side of the movable bin 304. A second limiting ring 703 is provided on the outside of the push rod 7, and the second limiting ring 703 is located on the fixed seat 3 outer side; the rotating shaft 502 rotatably connects the limiting strip 5 with the fixing seat 3, and the limiting teeth 501 can mesh with the toothed disc 8, so that the toothed disc 8 can only rotate in one direction, and prevent loosening without affecting the connection of the bolt body 1. The push rod 7 can contact and push one side of the limiting strip 5 through the push block 701, so that the limiting strip 5 moves around the axis of the rotating shaft 502 and compresses the spring 6, so that the limiting teeth 501 are separated from the toothed disc 8 to release the limit on the toothed disc 8, so that the bolt body 1 can be removed. The first limiting ring 702 and the second limiting ring 703 clearly define the sliding stroke of the push rod 7.

[0026] During installation, screw the fixing screw 302 into the connection object, fix the fixing seat 3 to the connection object, and then thread the bolt body 1 to the connection object. During the connection process of the bolt body 1, the toothed disc 8 and the limiting tooth 501 engage with each other and rotate in one direction, so that the bolt body 1 can only rotate in one direction and enter the connection object. After the bolt body 1 is connected to the limit stroke, the bent end 401 of the reinforcing wire 4 is passed through a group of through holes 303 and the reinforcement groove 101, and after passing through another group of through holes 303, the bent end 401 is manually bent to complete the installation.

[0027] Through the above steps, after the connection between the bolt body 1 and the connected object is set, the soft layer 2 fills the gap between the bolt body 1 and the connected object during the connection process to enhance the connection sealing. The spring 6 pushes the limit bar 5 and the toothed disc 8 to engage with each other for limiting, so that the toothed disc 8 and the fixing seat 3 can only rotate in one direction, preventing the bolt body 1 from rotating in the opposite direction due to vibration after connection and causing loosening. The reinforcing wire 4 can further fix the hexagonal seat 9 to the fixing seat 3 to prevent the bolt body 1 from rotating. Pressing the push rod 7 can push the limit bar 5 to compress the spring 6 to release the limit on the toothed disc 8.
