DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] like Figures 1 to 4As shown, a car tailgate leg cylinder includes a cylinder body 1, an output end of the cylinder body 1 is fixedly connected to a support pad 2, the width of the support pad 2 is greater than the diameter of the cylinder body 1, and a protective sleeve 3 is fixedly connected to the top side of the support pad 2. The protective sleeve 3 can be used to protect the cylinder body 1, which can greatly avoid the cylinder body 1 from directly colliding with other objects. Two rotating grooves are provided on one side of the support pad 2, and the inner walls of the two rotating grooves are rotatably connected to rotating blocks 4. One end of the two rotating blocks 4 is fixedly connected to an extension pad 5, and the width of the extension pad 5 is adapted to the width of the support pad 2. The protective sleeve 3 The outer surface of the adjusting plate 6 is fixedly connected to two adjusting plates 6, and a plurality of first fixed sockets 7 are provided on one side of the adjusting plate 6. The plurality of first fixed sockets 7 are evenly distributed on one side of the adjusting plate 6. A fixing bolt 8 is threadedly connected to the inner wall of a first fixed socket 7. An adjusting slot 9 is provided on the top side of the two adjusting plates 6. The first fixed socket 7 is connected to the adjusting slot 9. The inner walls of the two adjusting slots 9 are slidably connected with a slide plate 10. A second fixed socket 11 is provided on one side of the two slide plates 10. A movable plate 12 is fixedly connected to one side of the two slide plates 10 adjacent to the second fixed socket 11. The movable plate 12 is attached to one side of the adjusting plate 6. The movable plate 12 is slidably connected to the adjustment plate 6. The two movable plates 12 are fixedly connected to the first hinge seat 13 on one side away from the slide plate 10. The two first hinge seats 13 are hinged on one side with a connecting rod 14. The two connecting rods 14 are hinged on one end away from the first hinge seat 13 with a second hinge seat 15 fixedly connected to the extension pad 5. The bottom sides of the two extension pads 5 are fixedly connected with a number of anti-skid particles 16. When the tailgate leg cylinder is used on a softer ground, the fixing bolt 8 is separated from the first fixed socket 7 and the second fixed socket 11, and then the movable plate 12 drives the slide plate 10 to move downward. At this time, the first hinge seat 13 and the connecting rod 14 are connected to the second hinge seat 15. Under the action of the connecting rod 14 and the second hinge seat 15, the extension pad 5 drives the rotating block 4 to rotate, so that the extension pad 5 fits the ground, and is connected to the first fixed socket 7 and the second fixed socket 11 at the appropriate position through the fixing bolt 8 to fix the slide plate 10. At this time, the cylinder body 1 is supported by the supporting pad 2 and the extension pad 5 together, and is connected to the first fixed socket 7 and the second fixed socket 11 at the appropriate position through the fixing bolt 8, so that the extension pad 5 can be fixed at an inclined angle. The extension pad 5 at the inclined angle can fit with the ground with an inclined surface, thereby better ensuring the stability of the extension pad 5.

[0023] As an optional technical solution of the present invention, the outer surface of the protective sleeve 3 is fixedly connected to a mounting block 17, and a fixed anchor rod 18 is inserted on one side of the mounting block 17. The side of the extension pad 5 away from the rotating block 4 is fixedly connected to a fixing plate 19, and a fixing socket 20 is provided on one side of the fixing plate 19. After the extension pad 5 is fit into the ground, the fixing anchor rod 18 is separated from the mounting block 17, and then the fixing plate 19 is passed through the inside of the fixing socket 20 and inserted into the inside of the ground, and the end of the fixing anchor rod 18 is fit into the fixing plate 19, thereby fixing the fixing plate 19 and the extension pad 5.

[0024] As an optional technical solution of the present invention, a part of the cylinder body 1 is located inside the protective sleeve 3, and the maximum diameter of the cylinder body 1 is smaller than the inner diameter of the protective sleeve 3, so that the protective sleeve 3 interferes with the cylinder body 1 during the movement, so that the protective sleeve 3 can move smoothly.

[0025] As an optional technical solution of the present invention, the position of the fixing bolt 8 corresponds to that of the second fixing hole 11, and the size of the fixing bolt 8 is adapted to that of the second fixing hole 11, so that the fixing bolt 8 can be smoothly connected to the second fixing hole 11.

[0026] As an optional technical solution of the present invention, the shapes of the slide plate 10 and the adjustment groove 9 are both T-shaped, and the size of the slide plate 10 is adapted to the size of the adjustment groove 9, so that the slide plate 10 will not separate from the adjustment plate 6 during the movement.

[0027] As an optional technical solution of the present invention, the anti-slip particles 16 are made of rubber, and several anti-slip particles 16 are evenly distributed on one side of the extended pad 5. The bottom side of the anti-slip particles 16 and the bottom side of the supporting pad 2 are on the same horizontal plane. The anti-slip particles 16 can increase the friction between the extended pad 5 and the ground, thereby avoiding the situation where the extended pad 5 is easy to move.

[0028] As an optional technical solution of the present invention, the cross-sectional shape of the fixing anchor rod 18 is T-shaped, and the minimum diameter of the fixing anchor rod 18 is adapted to the diameter of the fixing socket 20 , so that the fixing anchor rod 18 can smoothly pass through the inside of the fixing socket 20 .

[0029] A car tailgate outrigger oil cylinder, the working principle is as follows:

[0030] When the tailgate leg cylinder is used on a soft ground, the fixing bolt 8 is separated from the first fixing socket 7 and the second fixing socket 11, and then the movable plate 12 drives the slide plate 10 to move downward. At this time, under the action of the first hinge seat 13, the connecting rod 14 and the second hinge seat 15, the extension pad 5 drives the rotating block 4 to rotate, so that the extension pad 5 is in contact with the ground, and is connected to the first fixing socket 7 and the second fixing socket 11 at the appropriate position by the fixing bolt 8 to fix the slide plate 10. At this time, the cylinder body 1 is supported by the support pad 2 and the extension pad 5.

[0031] In summary, the tailgate support leg oil cylinder of the automobile expands the supporting area of ​​the bottom of the tailgate support oil cylinder of the automobile through the coordinated arrangement of the supporting pad 2, the protective sleeve 3, the rotating block 4, the extending pad 5, the adjusting plate 6, the first fixed socket 7, the fixing bolt 8, the adjusting chute 9, the slide plate 10, the second fixed socket 11, the moving plate 12, the first hinge seat 13, the connecting rod 14, the second hinge seat 15 and the anti-skid particles 16, which greatly avoids the unstable support of the bottom of the tailgate support oil cylinder of the automobile when encountering a softer ground. The tailgate of the automobile can be stably supported, thereby ensuring the practicability of the tailgate leg cylinder. By coordinating the mounting block 17, the fixing anchor rod 18, the fixing plate 19 and the fixing socket 20, the extension pad 5 can be fixed when encountering a softer ground, thereby avoiding the positional displacement of the extension pad 5, so that the extension pad 5 and the supporting pad 2 can better support the cylinder body 1, further ensuring the stability of the tailgate support provided by the tailgate leg cylinder.
