[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figure 1 - Figure 4 shown, in this embodiment, the diesel engine side cover for a micro-tiller includes a side cover body 1. One side of the side cover body 1 is provided with a first installation groove 5. The inner wall of the first installation groove 5 is clamped with a first sealing ring 2. One side of the first sealing ring 2 is provided with a plurality of through holes 4 penetrating therethrough. One side of the outer surface of the side cover body 1 is provided with a plurality of installation threaded holes 11. One side of each of the plurality of installation threaded holes 11 is in through communication with one side of the first installation groove 5. The other side of the side cover body 1 is provided with a second installation groove 6. The inner wall of the second installation groove 6 is clamped with a second sealing ring 3. By respectively clamping the second sealing ring 3 and the first sealing ring 2 in the second installation groove 6 and the first installation groove 5, and then fitting one side of the second sealing ring 3 and one side of the first sealing ring 2 to the connection port of the diesel engine, the first sealing ring 2 and the second sealing ring 3 form a labyrinth seal, improving the sealing performance between the diesel engine and the side cover body 1, reducing the leakage of engine oil or lubricating oil in the diesel engine, and increasing the service life of the diesel engine. Among them, installation grooves 5 and 6 are also provided at the connection port of the diesel engine, and the other sides of the first sealing ring 2 and the second sealing ring 3 are respectively located in the installation grooves 5 and 6 at the connection port of the diesel engine.

[0021] As Figure 1 and Figure 3 shown, a plurality of reinforcing ribs 7 are fixedly connected to the inner wall of the side cover body 1. Through the structural design of the reinforcing ribs 7, the strength of the side cover body 1 can be improved, and the service life of the side cover body 1 can be increased.

[0022] As Figure 1 - Figure 4As shown in the figure, on the other side of the outer surface of the side cover body 1, a plurality of adjustment boxes 8 are fixedly connected. Through holes are formed in the upper ends of the plurality of adjustment boxes 8, and fixing bolts 10 are threadedly connected to the inner walls of the plurality of adjustment through holes 13. Clamping plates 9 are slidably connected to the inner walls of the plurality of adjustment boxes 8. The upper ends of the plurality of clamping plates 9 are respectively in contact with one ends of the plurality of fixing bolts 10. By buckling the side cover body 1 on the connection port of the diesel engine, and then sequentially rotating the plurality of fixing bolts 10, during the process that the plurality of fixing bolts 10 respectively enter the interiors of the plurality of adjustment boxes 8, the plurality of clamping plates 9 are pushed to move, so that the clamping plates 9 position the side cover body 1 and the diesel engine. Then, the installation screws are passed through the installation threaded holes 11 and aligned with the threaded holes on the diesel engine, and the installation screws are rotated to install the side cover body 1 on the diesel engine. After the fixation is completed, the plurality of fixing bolts 10 are rotated again so that the clamping plates 9 are pressed against the surface of the diesel engine, realizing the rapid positioning and fixation of the side cover body 1, improving the installation efficiency, and the pressing of the fixing bolts 10 against the surface of the diesel engine can make the connection of the side cover body 1 more firm.

[0023] As Figure 3 shown, a plurality of friction grooves 12 are formed on one side of each of the plurality of clamping plates 9. Through the structural design of the friction grooves 12, the friction force of the clamping plates 9 after being pressed against the diesel engine can be increased, further improving the connection stability between the side cover body 1 and the diesel engine.

[0024] As Figure 3 and Figure 4 shown, guide blocks 14 are fixedly connected to both sides of each of the plurality of clamping plates 9, and guide grooves 15 are formed on both sides of the inner walls of the plurality of adjustment boxes 8. The inner walls of the plurality of guide grooves 15 are respectively slidably connected to the outer surfaces of the plurality of guide blocks 14. Through the structural design of the guide grooves 15 and the guide blocks 14, the clamping plates 9 can be positioned, and it can effectively prevent the clamping plates 9 from deforming due to their own weight after the side cover body 1 is buckled on the diesel engine, improving the stability of the clamping plates 9.

[0025] The present utility model provides a side cover for a diesel engine of a micro-tiller, and the specific working principle is as follows:

[0026] When installing the diesel engine side cover on the diesel engine connection port, first, snap the second sealing ring 3 and the first sealing ring 2 into the second installation groove 6 and the first installation groove 5 respectively. Then, fasten the side cover body 1 onto the connection port of the diesel engine. After that, turn multiple fixing bolts 10 in sequence. During the process that the multiple fixing bolts 10 enter the interiors of multiple adjusting boxes 8 respectively, push multiple clamping plates 9 to move, so that the clamping plates 9 position the side cover body 1 and the diesel engine. Then, pass the installation screw through the installation threaded hole 11 and align it with the threaded hole on the diesel engine, and turn the installation screw to install the side cover body 1 on the diesel engine. After the fixation is completed, turn the multiple fixing bolts 10 again to press the clamping plates 9 against the surface of the diesel engine, thus completing the installation.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
