[0002] The cylinder head is a key component of the engine. It is located on the upper part of the cylinder block. Its main function is to seal the upper part of the cylinder. Together with the piston and the cylinder wall, it forms a combustion chamber. In this combustion chamber, the mixture of fuel and air is ignited or compressed, generating power to push the piston to move. The cylinder head is usually equipped with a valve cover. When the valve cover is installed between the cylinder head, it is usually necessary to use multiple bolts to fix it to prevent the valve cover and the cylinder head from loosening and leaking. However, this fixing method requires twisting multiple bolts between the valve cover and the cylinder head during installation and maintenance and disassembly, resulting in low installation and maintenance efficiency.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figures 1 to 3 The utility model provides a technical solution: a cylinder head that is convenient for installing a valve chamber cover, comprising a cylinder head main body 1, and a valve chamber cover body 2 that is detachably mounted on the top of the cylinder head main body 1. The valve chamber cover body 2 can prevent impurities such as dust and moisture from entering the valve chamber and protect internal components. A dovetail block is fixedly connected to the valve chamber cover body 2, and a dovetail groove that matches the dovetail block is opened on the cylinder head main body 1. The dovetail block and the dovetail groove are connected to each other to achieve the docking between the cylinder head main body 1 and the valve chamber cover body 2, thereby improving the docking efficiency between the cylinder head main body 1 and the valve chamber cover body 2. A fastening bolt 10 is threadedly provided on the valve chamber cover body 2, and the fastening bolt 10 is threadedly connected to the cylinder head main body 1. After the cylinder head main body 1 and the valve chamber cover body 2 are connected, the fixing between the cylinder head main body 1 and the valve chamber cover body 2 can be achieved by tightening the fastening bolt 10, thereby preventing the valve chamber cover body 2 from sliding left and right.

[0016] Among them, the dovetail block includes a first dovetail block 6 and a second dovetail block 8, and the dovetail groove includes a first dovetail groove 7 and a second dovetail groove 9. The first dovetail block 6 and the first dovetail groove 7 cooperate. After the first dovetail block 6 and the first dovetail groove 7 cooperate, the edges of the cylinder head body 1 and the valve chamber cover body 2 can be docked. The first dovetail groove 7 and the second dovetail groove 9 cooperate to dock the middle of the cylinder head body 1 and the valve chamber cover body 2. There are two first dovetail blocks 6, which are distributed on both sides of the bottom of the valve chamber cover body 2, so that the edges on both sides of the cylinder head body 1 and the valve chamber cover body 2 can be quickly docked. The second dovetail block 8 is distributed in the middle of the valve chamber cover body 2.

[0017] Among them, a valve chamber is enclosed between the cylinder head body 1 and the valve chamber cover body 2. An intake valve seat 3 and an exhaust valve seat 4 are provided on the cylinder head body 1. The intake valve seat 3 and the exhaust valve seat 4 are connected to the valve chamber. The intake valve seat 3 is responsible for allowing the air and fuel mixture to enter the cylinder, and the exhaust valve seat 4 is responsible for discharging the exhaust gas after combustion. The normal operation of the valve is crucial to the intake and exhaust efficiency of the engine.

[0018] The cylinder head body 1 is provided with a coolant channel 5, which is used to circulate coolant to take away the heat generated by combustion and prevent the engine from overheating.

[0019] Specifically, align the first dovetail block 6 and the second dovetail block 8 with the first dovetail groove 7 and the second dovetail groove 9 respectively and then tighten the fastening bolts 10 to fix the cylinder head body 1 and the valve chamber cover body 2, thereby preventing the valve chamber cover body 2 from sliding left and right. The cylinder head body 1 and the valve chamber cover body 2 can be quickly installed. Loosen the fastening bolts 10 and push the valve chamber cover body 2 to separate the valve chamber cover body 2 from the cylinder head body 1.
