[0022] Reference Figure 1-5 The utility model embodiment is a rear bracket of an engine lower guard plate, which includes a mounting frame 1 of a U-shaped structure, a movable groove 2 is provided inside the mounting frame 1, two connecting plates 3 are slidably connected inside the movable groove 2, the bottom of the connecting plate 3 is fixedly connected with a bottom plate 5 slidably connected to the bottom of the mounting frame 1, and a top plate 4 is installed on the top of the connecting plate 3, a threaded groove is provided inside the connecting plate 3, and through holes are provided inside the top plate 4 and the bottom plate 5, and two connecting rods 8 slidably connected to the corresponding connecting plates 3 and both of which are set as T-shaped structures are symmetrically fixedly connected at the bottom of the top plate 4, a plurality of positioning holes 6 are symmetrically provided inside the top side of the mounting frame 1 and on both sides of the movable groove 2, and a positioning block 7 is fixedly connected to the bottom of the top plate 4 and on one side close to the positioning hole 6, and the positioning block 7 is plugged into the adjacent positioning hole 6;

[0023] When the connecting plate 3 moves inside the movable groove 2, the top plate 4 and the bottom plate 5 at the upper and lower ends can limit the connecting plate 3 well, and the top plate 4 is connected to the connecting plate 3 by the connecting rod 8, so as to realize the up and down movement of the top plate 4. When the top plate 4 moves upward, the positioning block 7 is driven to separate from the positioning hole 6, and the connecting plate 3 is moved to the corresponding position according to the position of the connecting hole of the different lower guard plates. The connecting hole of the lower guard plate is connected with the threaded groove of the connecting plate 3 by bolts, so as to complete the connection work between the lower guard plate and the mounting frame 1. When the bolts are tightened, the top plate 4 is driven to move downward so that the positioning block 7 is matched with the positioning hole 6 for connection, thereby ensuring the stability of the connecting plate 3, so as to ensure the stable connection between the lower guard plate and the mounting frame 1. By adjusting the position of the connecting plate 3 on the mounting frame 1, the mounting frame 1 can adjust the position of the connecting plate 3 according to the model of the lower guard plate, so as to adapt to different types of engine lower guard plates, and has strong practicality.

[0024] Both ends of the mounting frame 1 are slidably connected with a mounting plate 10 with an internal hollow structure. The mounting plate 10 is provided with an adjustment component connected to the end of the mounting frame 1. The adjustment component includes a screw 11 rotatably connected to the inner wall of the hollow structure of the mounting plate 10 and away from the side of the mounting frame 1, an operating portion 12 opened in the mounting plate 10 and close to the side of the screw 11 rotatably connected, and a hexagonal groove 13 opened at one end of the screw 11 close to the operating portion 12. The end of the screw 11 close to the operating portion 12 penetrates the mounting plate 10 and extends into the operating portion 12. The end of the screw 11 close to the mounting frame 1 is threadedly connected to the inside of the mounting frame 1. The inside of the operating portion 12 can be used for the movement of a hexagonal wrench. After the hexagonal wrench is connected to the hexagonal groove 13, the screw 11 can be driven to rotate by operating the hexagonal wrench. Under the action of the rotating screw 11, the protruding length of the mounting frame 1 inside the mounting plate 10 can be adjusted, thereby adjusting the horizontal distance between the connecting plate 3 and the mounting plate 10, so as to better adjust the position of the connecting plate 3 according to different types of guard plates for connection work.

[0025] A flange nut 14 is provided at the top of the mounting frame 1 close to the operating portion 12, and anti-slip teeth are provided on the bottom side of the flange nut 14.

The mounting frame 1 of the complete structure not only improves the strength of the mounting frame 1, but also simplifies the manufacturing process. The folded edges of the mounting frame 1 are fixedly connected with reinforcing ribs 9, which can increase the cross-sectional area of ​​the mounting frame 1 at the folded edges, provide additional support and stability, and make the mounting frame 1 more durable when subjected to impact and vibration from the road surface.

[0027] Working principle: When the connecting plate 3 moves inside the movable groove 2, the top plate 4 and the bottom plate 5 at the upper and lower ends can well limit the connecting plate 3, and the top plate 4 is connected to the connecting plate 3 by the connecting rod 8, so that the top plate 4 can be moved up and down. When the top plate 4 moves upward, it drives the positioning block 7 to separate from the positioning hole 6, and moves the connecting plate 3 to the corresponding position according to the position of the connecting hole of the different lower guard plates. The connecting hole of the lower guard plate is connected with the threaded groove of the connecting plate 3 by bolts, so that the connection work between the lower guard plate and the mounting frame 1 can be completed, and the bolts are tightened while driving the top plate 4 to move downward so that the positioning block 7 is matched and connected with the positioning hole 6, thereby ensuring the stability of the connecting plate 3 and ensuring the stable connection between the lower guard plate and the mounting frame 1;

[0028] After the hexagonal wrench is connected to the hexagonal groove 13, the screw rod 11 can be driven to rotate by operating the hexagonal wrench. Under the action of the rotating screw rod 11, the extension length of the mounting frame 1 inside the mounting plate 10 can be adjusted, so that the horizontal distance between the connecting plate 3 and the mounting plate 10 can be adjusted to better adjust the position of the connecting plate 3 according to different types of guard plates for connection work;

[0029] By adjusting the position of the connecting plate 3 on the mounting frame 1, the mounting frame 1 can adjust the position of the connecting plate 3 according to the model of the lower guard plate, which is convenient for adapting to different models of engine lower guard plates and has strong practicality.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
