DETAILED DESCRIPTION

[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5A light automobile end cover is shown, comprising a cylinder head 1 and an end cover body 2. A guide structure 3 is provided on the cylinder head 1. The guide structure 3 comprises a plurality of connecting columns 4 installed on the cylinder head 1. A limit block 5 is fixedly installed on the connecting column 4. The limit block 5 is provided with a plurality of notches 6. The end cover body 2 is provided with a plurality of guide openings 7. A fixing block 8 used in conjunction with the limit block 5 is fixedly installed inside the guide opening 7. By setting the guide structure 3, a guiding effect can be provided when the end cover body 2 is installed on the cylinder head 1, so as to avoid the various sealing openings on the end cover body 2 from being worn and enlarged due to position offset, and the installation can be carried out quickly; the guide opening 7 on the end cover body 2 is aligned with the limit block 5 and inserted. During this installation process, the limit block 5 and the grooves between the multiple fixed blocks 8 are adapted and inserted until the fixed block 8 is inserted into the groove 6 and contacts the limit block 5. Then the cylinder head 1 and the end cover body 2 can be installed. This structure can quickly install the cylinder head 1 and the end cover body 2, and this installation method will not cause wear to the sealing holes on the end cover body 2, thereby avoiding water and air from entering the cylinder through the worn holes, thereby preventing leakage or damage.

[0023] like Figure 4 As shown, a connecting block 9 is fixedly installed at the bottom of the connecting column 4, and a plurality of mounting holes 10 adapted to the connecting block 9 are opened on the cylinder head 1, and a plurality of grooves are opened on the inner side of the mounting hole 10. By setting the connecting block 9, the mounting hole 10 and the groove, the connecting column 4 is adjusted so that the angle of the connecting block 9 is consistent with the mounting hole 10, and the connecting column 4 is inserted into the interior of the mounting hole 10, and then the connecting column 4 is rotated so that the connecting block 9 is stuck in the groove on the inner side of the mounting hole 10, and the connecting column 4 can be fixed on the cylinder head 1, and the connecting column 4 is rotated so that the connecting block 9 is disengaged from the groove. After disengagement, when the angle of the connecting block 9 is consistent with the mounting hole 10, the connecting column 4 can be pulled out, which is convenient for disassembly and replacement when the connecting column 4 is damaged.

[0024] like Figure 5 As shown, a closing cover 11 is provided on one side of the end cover body 2, and a plurality of clamping blocks 12 adapted to the guide openings 7 are fixedly installed on one end of the closing cover 11; after the cylinder head 1 and the end cover body 2 are installed, the closing cover 11 can be covered on the end cover body 2 by aligning the plurality of clamping blocks 12 with the plurality of guide openings 7, which can seal the end cover body 2 and prevent water and gas from entering the cylinder through the guide openings 7, or preventing gas from leaking inside the cylinder.

[0025] like Figure 5 As shown, a magnetic ring 13 is fixedly installed at one end of the closing cover 11, and a magnetic slot 14 magnetically connected to the magnetic ring 13 is opened on the end cover body 2; after the magnetic ring 13 is inserted into the magnetic slot 14 and attracted to each other, the closing cover 11 can be further fixed to prevent the closing cover 11 from loosening and falling off. Due to the characteristics of the magnetic ring 13 and the magnetic slot 14, the closing cover 11 can be removed by pulling it between them.

[0026] like Figure 3 As shown, a plurality of threaded holes 15 are provided on the limit block 5 and the fixed block 8, and the fixed block 8 and the limit block 5 are connected by bolts 16; after the limit block 5 and the fixed block 8 are fitted together, the bolts 16 are tightened into the threaded holes 15 until the limit block 5 and the fixed block 8 are fixed together, which can further improve the stability of the connection between the cylinder head 1 and the end cover body 2.

[0027] like Figure 5 As shown, a sealing ring 17 is fixedly installed at one end of the end cover body 2. Through the setting of the sealing ring 17, the connection between the cylinder head 1 and the end cover body 2 can be sealed to prevent water vapor from penetrating into the cylinder through the gap or air leakage in the cylinder.

[0028] like Figure 1 As shown, the surface of the end cover body 2 is provided with a chrome coating 18; since the chrome layer has extremely high hardness and good corrosion resistance, it can significantly improve the wear resistance of the end cover, and prevent the end cover body 2 from being damaged by corrosion and excessive friction, thereby affecting its normal use.

[0029] The working process of a light automobile end cover provided in this embodiment is as follows:

[0030] Align the guide opening 7 on the end cover body 2 with the limit block 5 and insert it. During the installation process, the limit block 5 is inserted into the grooves between the multiple fixing blocks 8 until the fixing block 8 is inserted into the groove 6 and contacts the limit block 5. The cylinder head 1 and the end cover body 2 can be installed. This structure can quickly install the cylinder head 1 and the end cover body 2, and this installation method will not cause wear to the sealing holes on the end cover body 2, thereby preventing water and air from entering the cylinder through the worn holes, preventing leakage or damage.

[0031] The above description shows and describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein.
