[0002] An engine is a machine that converts other forms of energy into mechanical energy. These include internal combustion engines, external combustion engines, jet engines, electric motors, and nuclear-powered engines. They are primarily used in vehicles such as automobiles, ships, and nuclear submarines. For example, the basic principle of a nuclear submarine's propulsion system is to use the heat generated by nuclear fission reactions in a nuclear reactor to heat water, generating steam, which drives a steam turbine to generate mechanical energy. The cylinder head is a key component of an engine and is typically bolted to the cylinder block. The constant movement of the piston rod within the cylinder generates friction, releasing numerous tiny impurities that are incorporated into the engine oil and can cause long-term damage to the engine. Therefore, operators must remove all bolts from the cylinder head to open the engine for internal inspection. However, removing and installing each bolt on the cylinder head requires operators to carry tools such as wrenches, which complicates and inconveniences the task. Furthermore, because each bolt is exposed, misoperation by unauthorized personnel is unavoidable, leading to safety accidents. Utility Model Content

[0021] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0022] refer to Figure 1 、 Figure 2 、 Figure 3 An engine cylinder head includes a cylinder block 1 and a cylinder head body 2. Four first mounting positions 101 are arranged around the cylinder block 1, and four second mounting positions 201 are arranged around the cylinder head body 2. Each first mounting position 101 corresponds to each second mounting position 201, and the second mounting position 201 is detachably connected to its corresponding first mounting position 101 through an anti-misoperation mechanism 3.

[0023] The anti-misoperation mechanism 3 includes a connecting column 31, a driving rod 32 and an operating handle 33. The second mounting position 201 is provided with a sliding groove 202 for the connecting column 31 to slide and connect. A travel ring 314 is provided on the upper part of the connecting column 31. The inner wall of the sliding groove 202 is provided with a travel groove 204 for the travel ring 314 to slide and connect, thereby preventing the connecting column 31 from detaching from the second mounting position 201.

[0024] The portion of the lower portion of the connecting post 31 extending out of the chute 202 is detachably connected to the first mounting position 101. Preferably, the first mounting position 101 is provided with a mounting hole 102 for the lower portion of the connecting post 31 to be threadedly connected.

[0025] An operating hole 203 is provided on the inner wall of the slide groove 202 and passes through the top of the cylinder head body 2. The drive rod 32 is telescopically and rotatably arranged on the operating hole 203. A reset elastic member 4 is provided between the drive rod 32 and the slide groove 202, so that the lower part of the drive rod 32 has a tendency to move downward.

[0026] The upper part of the connecting column 31 is provided with a coaxial driving groove 311 and a movable groove 312. The inner wall of the driving groove 311 is formed with a plurality of driving surfaces 313. The plurality of driving surfaces 313 are evenly distributed in a circular array. Preferably, the driving surfaces 313 are surrounded to form a regular hexagon.

[0027] The inner diameter of the movable groove 312 is larger than the outer diameter of the driving groove 311. The lower part of the driving rod 32 is fixedly connected to the driving part 321. The outer diameter of the driving rod 32 is smaller than the inner diameter of the driving part 321. The upper part of the driving rod 32 extends out of the operating hole 203 and is provided with an operating handle 33.

[0028] The top surface of the cylinder head body 2 is provided with a receiving groove 8 for accommodating the operating handle 33 at a position relative to the operating hole 203. An operating gap is formed between the inner wall of the receiving groove 8 and the operating handle 33. Under the action of the reset elastic member 4, the driving rod 32 translates downward so that the driving part 321 is located in the movable groove 312, so that the operating handle 33 enters the receiving groove 8. At this time, the driving part 321 is telescopically rotatably set in the movable groove 312, so that the driving part 321 drives the non-interfering connecting column 31, thereby avoiding misoperation by non-staff.

[0029] When the staff disassembles and assembles the cylinder body 1 and the cylinder head body 2, there is no need to carry tools. By holding the operating handle 33, the driving rod 32 is lifted to allow the driving part 321 to be inserted into the driving groove 311. When the driving part 321 is located in the driving groove 311, the outer wall of the driving part 321 and the inner wall of the driving groove 311 are in contact with each other. At this time, the staff can rotate the driving rod 32 by operating the handle 33, so that the driving part 321 drives the connecting column 31 to rotate to achieve detachable rotation between the connecting column 31 and the first mounting position 101, which is more convenient to operate.

[0030] Preferably, the part of the driving rod 32 extending into the slide groove 202 is sleeved with a first bearing member 5, the inner wall of the slide groove 202 is embedded with a second bearing member 6, the inner ring wall of the second bearing member 6 cooperates with the inner wall of the operating hole 203, the first bearing member 5 and the second bearing member 6 are coaxially arranged, and the outer ring of the first bearing member 5 and the outer ring of the second bearing member 6 are both provided with a mounting ring 7. The reset elastic member 4 is a spring structure and its two ends are respectively sleeved on the outer walls of the two mounting rings 7 to prevent the driving rod 32 from affecting the reset elastic member 4 when rotating.

[0031] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
