[0033] The outer part of the clamping head 2 is sleeved with a spring 5, which is designed as a key role to provide elastic force. The bottom of the spring 5 is fixedly connected with an extrusion shaft 6, which is designed as a transmission component to convert the elastic force of the spring 5 into actual fixed force. The outer part of the extrusion shaft 6 is slidingly connected in the inner part of the butt joint 1 and the outer part of the clamping head 2. The inner part of the extrusion shaft 6 is provided with an extrusion groove 7, which is designed as a certain space and guide for the movement of the clamping column 3. The inner part of the clamping column 3 is provided with a sliding groove 8, which is designed as a space and constraint for the sliding of the clamping column 3 in the clamping head 2. The outer part of the clamping ball 4 is clampedly connected in the inner part of the sliding groove 8. The bottom of the butt joint 1 is fixedly connected with a heat insulation assembly for engine heat insulation

[0034] Referring to Figure 1 , Figure 4 The heat insulation assembly comprises a heat insulation pad body 9, which is designed as a connecting part between the heat insulation assembly and the connecting structure. The top of the heat insulation pad body 9 is fixedly connected with the bottom of the plurality of clamping columns 3. The bottom of the heat insulation pad body 9 is fixedly connected with a fire-retardant layer 12, which is designed as a protection for the engine cover in fire prevention. The material of the fire-retardant layer 12 is rock wool, and the fire-retardant layer 12 can prevent fire spreading. The bottom of the fire-retardant layer 12 is fixedly connected with a low thermal conductivity layer 11, which is designed to reduce the conduction efficiency of heat as much as possible. The bottom of the low thermal conductivity layer 11 is fixedly connected with a corrosion-resistant layer 10. The material of the low thermal conductivity layer 11 is expanded perlite, and the low thermal conductivity layer 11 can reduce the efficiency of heat transfer. The corrosion-resistant layer 10 is designed to resist corrosion, so that the heat insulation assembly can maintain a good state in the harsh engine compartment environment. The material of the corrosion-resistant layer 10 is glass wool, and the corrosion-resistant layer 10 can resist the corrosion of oil substances in use.

[0035] Working principle: when the engine cover of the automobile needs to be quickly installed, the plurality of butt joints 1 are attached to the engine cover, the extrusion shaft 6 is pressed to extrude the spring 5, at this time the clamping columns 3 on the heat insulation pad body 9 are butted into the fixed clamping head 2 in the butt joint 1, at this time the extrusion shaft 6 is released, the spring 5 releases the elastic force to push the extrusion shaft 6, the plurality of clamping balls 4 are extruded to be clamped with the sliding groove 8, so that the clamping columns 3 are fixed, thereby realizing quick butt joint installation, and achieving quick butt joint installation of the engine cover of the automobile, effectively improving the installation efficiency and ensuring the stability of the installation.

The low-thermal-conductivity layer 11 uses expanded perlite as the material. The expanded perlite contains a large number of small closed pores, which form a good heat insulation space. The fire-retardant layer 12 uses rock wool as the material. The rock wool is an inorganic non-combustible material, which will not burn in a high-temperature environment and has a high melting point. When encountering a flame or a high-temperature heat source, the rock wool can absorb a large amount of heat and undergo physical and chemical changes during the temperature rising process, such as thermal decomposition to produce some non-combustible gases. These gases can dilute the oxygen concentration in the surrounding air, thereby inhibiting the continuous combustion reaction.
