[0032] 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.

[0033] Example 1, please refer to Figures 1 to 7 The utility model provides a technical solution: a quickly assembled marine engine cylinder head, comprising a cylinder head body 1, a plurality of positioning posts 101 fixedly mounted on the top of the cylinder head body 1, a sealing gasket 102 movably connected to the top of the cylinder head body 1, a plurality of positioning grooves 103 are provided inside the sealing gasket 102, a plurality of positioning posts 101 are movably embedded in the interior of the positioning grooves 103, a plurality of connecting pieces 104 are fixedly mounted on the outer surface of the cylinder head body 1, a plurality of connecting pieces 104 are provided with first threaded holes 105 inside the plurality of connecting pieces 104, a plurality of second threaded holes 106 are provided inside the sealing gasket 102, and a plurality of connecting pieces 104 are fixedly mounted on the outer surface of the cylinder head body 1. 04 is movably connected with bolts 107, and the outer surfaces of multiple bolts 107 are threadedly connected to the inner surface of the first threaded hole 105, and multiple bolts 107 are matched with the second threaded hole 106. A crankshaft connecting groove 110 is opened on the left side of the interior of the cylinder head body 1, and multiple reinforcing ribs 111 are provided on both sides of the outer surface of the cylinder head body 1. Handles 112 are fixedly installed on both sides of the bottom of the cylinder head body 1, and the outer surfaces of the two handles 112 are fixedly covered with anti-slip sleeves 113. Multiple spark plug grooves 108 are provided inside the cylinder head body 1, and rotating shaft connecting grooves 109 are opened on both sides of the interior of the cylinder head body 1.

[0034] In this embodiment, the personnel first pick up the gasket 102 and place it on the top of the cylinder head body 1, and then press the gasket 102 downward so that the positioning column 101 is embedded in the inside of the positioning groove 103, and the bottom of the gasket 102 is fitted against the top of the cylinder head body 1. Then the personnel grasps the handle 112 so that the palm is fitted against the anti-slip sleeve 113, and lifts the cylinder head body 1 by the handle 112, and places it on the top of the engine cylinder, while making the gasket 102 fit the engine and drive the positioning column 101 to be embedded into the inside of the engine cylinder connecting groove, and then the crankshaft is embedded into the inside of the crankshaft connecting groove 110, and the rotating shaft is embedded into the inside of the rotating shaft connecting groove 109, and the spark plug is embedded into the inside of the spark plug groove 108. Then the personnel tightens the bolts inside the forward connecting member 104 107, so that it slides downward inside the first threaded hole 105. After it slides to a certain extent, it will pass through the second threaded hole 106 on the gasket 102 and embed into the inside of the engine threaded hole. Personnel can weld reinforcing ribs 111 on the cylinder head body 1 to improve the strength of the cylinder head body 1. Through the arrangement of the gasket 102 and the bolt 107 structure, not only can the positioning column 101 and the positioning groove 103 be used to ensure that the gasket 102 is accurately positioned during installation, thereby reducing errors in human operation and ensuring good sealing between the cylinder head body 1 and the engine, but also through the arrangement of the bolt 107 and the second threaded hole 106 structure, when removing the gasket 102, personnel only need to loosen the bolt 107, thereby simplifying the disassembly process.

[0035] Example 2, as Figures 1 to 7 As shown, a placement groove 2 is opened inside the cylinder head body 1, and a cooling pipe 201 is fixedly embedded in the placement groove 2. A water inlet pipe 202 is fixedly installed on the right end of the cooling pipe 201, and a water outlet pipe 203 is fixedly installed on the other end of the cooling pipe 201. The outer surface of the water inlet pipe 202 is fixedly embedded in the right side of the interior of the cylinder head body 1, a plurality of air outlet seats 205 are provided on the front side of the interior of the cylinder head body 1, and a plurality of air inlet seats 204 are provided on the rear side of the interior of the cylinder head body 1. The outer surface of the water outlet pipe 203 is fixedly embedded in the left side of the interior of the cylinder head body 1.

[0036] In this embodiment, personnel can connect the intake pipe to the intake seat 204 and the outlet pipe to the outlet seat 205, so that the gas circulates inside the cylinder head body 1. At the same time, personnel can connect the water inlet pipe 202 to the water pipe, and transport the coolant through the water pipe, so that the coolant enters the cooling pipe 201 inside the placement tank 2 synchronously with the water inlet pipe 202. When the coolant enters the cooling pipe 201, it will circulate from right to left in the cooling pipe 201, thereby cooling the cylinder head body 1. At the same time, personnel can extract the coolant from the cooling pipe 201 through the water outlet pipe 203. The arrangement of the cooling pipe 201 and the water inlet pipe 202 structure not only enables the coolant to circulate effectively and quickly take away the heat of the cylinder head body 1 to prevent overheating and keep the engine cylinder at an ideal operating temperature, but also the design of the coolant flowing from right to left helps it to be evenly distributed inside the cooling pipe 201, thereby enhancing the cooling effect and reducing the risk of local overheating.

[0037] Working principle: When in use, the personnel first pick up the gasket 102 and place it on the top of the cylinder head body 1, and then press the gasket 102 downward so that the positioning column 101 is embedded in the positioning groove 103, and the bottom of the gasket 102 is fitted against the top of the cylinder head body 1. Then the personnel grasps the handle 112 so that the palm of the hand fits the anti-slip sleeve 113, and lifts the cylinder head body 1 through the handle 112, and places it on the top of the engine cylinder. At the same time, the gasket 102 fits the engine and drives the positioning column 101 to be embedded in the inside of the engine cylinder connecting groove. Then, the crankshaft is embedded in the inside of the crankshaft connecting groove 110, and the rotating shaft is embedded in the inside of the rotating shaft connecting groove 109. At the same time, the spark plug is embedded in the inside of the spark plug groove 108. Then, the personnel inserts the spark plug into the inside of the positive connecting member 104. The bolt 107 slides downward inside the first threaded hole 105. After sliding to a certain extent, it passes through the second threaded hole 106 on the gasket 102 and is embedded in the engine threaded hole. The personnel can weld the reinforcing rib 111 on the cylinder head body 1 to improve the strength of the cylinder head body 1. The arrangement of the gasket 102 and the bolt 107 structure can not only ensure that the gasket 102 is accurately positioned during the installation process through the cooperation of the positioning column 101 and the positioning groove 103, thereby reducing the error of human operation and ensuring a good seal between the cylinder head body 1 and the engine, but also can be arranged with the bolt 107 and the second threaded hole 106 structure, so that when removing the gasket 102, the personnel only need to loosen the bolt 107, thereby simplifying the disassembly process. During use, personnel can connect the air intake pipe to the air intake seat 204 and the air outlet pipe to the air outlet seat 205, so that the gas circulates inside the cylinder head body 1. At the same time, personnel can connect the water inlet pipe 202 to the water pipe and transport the coolant through the water pipe so that it can enter the cooling pipe 201 inside the placement tank 2 synchronously with the water inlet pipe 202. When the coolant enters the cooling pipe 201, it will circulate from right to left inside the cooling pipe 201, thereby cooling the cylinder head body 1. At the same time, personnel can extract the coolant inside the cooling pipe 201 through the water outlet pipe 203. The setting of the cooling pipe 201 and the water inlet pipe 202 structure not only enables the coolant to circulate effectively and quickly take away the heat of the cylinder head body 1 to prevent overheating and keep the engine cylinder at an ideal operating temperature, but also the design of the coolant flowing from right to left helps it to be evenly distributed inside the cooling pipe 201, thereby enhancing the cooling effect and reducing the risk of local overheating.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
