[0002] Chinese patent document CN218093718U discloses a cylinder head, relating to the field of cylinder technology, which includes a cover body, a liquid-blocking assembly, and at least three one-way valves. The cylinder head provided by this invention, by incorporating the cover body, liquid-blocking assembly, and at least three one-way valves, allows coolant to circulate inside the cover body through the inlet and outlet. During its flow, the coolant carries away heat from the cylinder head. Furthermore, the liquid-blocking assembly and the at least three one-way valves increase the time the coolant remains inside the cover body, thus extending the heat exchange time between the coolant and the cylinder head. Therefore, the cylinder head of this invention facilitates heat dissipation and is beneficial for the actual heat dissipation of the cylinder.

[0003] However, in the above-mentioned solutions and existing technologies, in order to achieve sound insulation and noise reduction of the cylinder head, a sound insulation cotton sleeve needs to be laid on the outside of the cylinder head. The sound insulation cotton sleeve is usually fixed by a buckle. As the cylinder head vibrates during use, the buckle is prone to loosening, which makes it impossible to ensure that the sound insulation cotton sleeve is stably attached to the cylinder head. Improvement and optimization are needed. Utility Model Content

[0024] The mounting block 2 is inserted into the mounting groove 4, exposing the slot 5. The U-shaped pressure plate 6 is snapped into the slot 5 and engages with the mounting block 2 on its inner side corner, thereby positioning and installing the U-shaped pressure plate 6 to press and limit the sound insulation cotton sleeve 3.

[0025] The U-shaped pressure plate 6 in the installation assembly is symmetrically connected with inserts 7 on its side wall. The side wall of the insert 7 has a limiting bead groove 8. The limiting frame 9 is sleeved with the two inserts 7. The two ends of the fixing block 10 are connected to the two side walls of the limiting frame 9.

[0026] After the U-shaped pressure plates 6 on both sides are installed, their ends are snapped together. The installation of the limiting frame 9 allows the inserts 7 on the U-shaped pressure plates 6 on both sides to be fitted into the grooves of the limiting frame 9, thereby fixing the position of the U-shaped pressure plates 6.

[0027] The fixed block 10 has a sliding bead groove 11, and a moving groove 12 is provided on the side wall of the sliding bead groove 11.
