[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-5 As shown, this utility model provides a technical solution:

[0021] A lower left bracket for a car rear cover includes a bracket body 1. A ball head pin 2 is fixedly connected to the bracket body 1 by riveting. An mounting ring 3 is fixedly connected to the bracket body 1. A protective sleeve 4 is fixedly connected to the top of the mounting ring 3. A connecting ring 5 is fixedly connected to the top of the protective sleeve 4. A protective cover 6 is provided on the top of the connecting ring 5. A locking component is provided on the protective cover 6. The protective cover 6 is connected to the connecting ring 5 on the protective sleeve 4 through the locking component. The protective cover 6 and the protective sleeve 4 cover the ball head pin 2. The protective cover 6 and the protective sleeve 4 can effectively prevent dust, sand and other impurities from contacting the ball head pin 2 during the transportation of the parts.

[0022] The locking assembly includes a first connecting block 7, which is fixedly connected to the top of the protective cover 6. Telescopic holes 8 are provided on both sides of the first connecting block 7 that are far apart from each other. A limit rod 9 is slidably connected to the inner wall of each telescopic hole 8. A spring 10 is sleeved around the outer periphery of the limit rod 9. A second connecting block 11 is fixedly connected to one side of the limit rod 9. A pin 12 is fixedly connected to the bottom of the second connecting block 11. A limit block 13 is fixedly connected to the bottom of the pin 12. A pressing plate 14 is fixedly connected to the top of the second connecting block 11. Multiple anti-slip strips 15 are fixedly connected to the side of the pressing plate 14 away from the first connecting block 7. A pair of through slots 16 are provided on the protective cover 6, each slot 16 being adapted to the pin 12. A sealing gasket 17 is provided at the bottom of the protective cover 6. Multiple connecting holes 18 are provided on the connecting ring 5. The radius of the pin 12 is smaller than the radius of the connecting hole 18, and the size of the limit block 13 is slightly smaller than the radius of the connecting hole 18, so that the pin 12... Pin 12 can be inserted into connecting hole 18, and limiting block 13 can pass through connecting hole 18. Spring 10 pushes pin 12 to press against one end of through groove 16 through connecting block 2 11, so that limiting block 13 is offset from connecting hole 18. Connecting hole 18 can prevent pin 12 from slipping out of connecting hole 18. At this time, sealing gasket 17 is compressed, and protective cover 6 and protective sleeve 4 are sealed together. When protective cover 6 needs to be removed, connecting block 2 11 is moved by pressing plate 14. Connecting block 2 11 drives limiting rod 9 to slide into telescopic hole 8.

[0023] The bracket body 1 is provided with a main positioning reference hole 19 and a secondary positioning reference hole 20, and the bracket body 1 is connected to the vehicle body through the main positioning reference hole 19 and the secondary positioning reference hole 20.

[0024] The working principle of this utility model is as follows:

[0025] The radius of the pin 12 is smaller than the radius of the connecting hole 18, and the size of the limiting block 13 is slightly smaller than the radius of the connecting hole 18, so that the pin 12 can be inserted into the connecting hole 18 and the limiting block 13 can pass through the connecting hole 18. The spring 10 pushes the pin 12 tightly against one end of the through groove 16 through the connecting block 11, so that the limiting block 13 is offset from the connecting hole 18. The connecting hole 18 can prevent the pin 12 from slipping out of the connecting hole 18. At this time, the sealing gasket 17 is compressed, and the connecting ring 5 on the protective cover 6 and the protective sleeve 4 are sealed together. The protective cover 6 and the protective sleeve 4 cover the ball head pin 2. The protective cover 6 and the protective sleeve 4 can effectively prevent dust, sand and other impurities from contacting the ball head pin 2 during the transportation of the parts, which greatly reduces the risk of wear of the ball head pin 2 due to the intrusion of impurities during subsequent installation and extends its service life.

[0026] When the ball head pin 2 is connected to the ball seat, the pressing plate 14 drives the connecting block 11 to move. The connecting block 11 drives the limiting rod 9 to slide into the telescopic hole 8, and the spring 10 is further compressed. At the same time, the connecting block 11 drives the pin 12 to press against the other end of the through groove 16. At this time, the limiting block 13 corresponds to the connecting hole 18. The pressing plate 14 can drive the pin 12 to be pulled out from the connecting hole 18. The pin 12 drives the limiting block 13 to pass through the connecting hole 18, so that the protective cover 6 and the connecting ring 5 are separated. The connecting ring 5 can be connected to the ball seat through the connecting hole 18. The protective sleeve 4 continues to provide protection for the ball head pin 2.

[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
