[0024] The prior art generally insulates and sounds the engine and the equipment in the front cabin of the car by laying two heat-insulating and sound-proofing pads on the top of the engine for fixing. However, there will be a gap in the middle when the two pieces of heat-insulating and sound-proofing pads are spliced together, and heat and sound will dissipate through the gap, making it impossible to effectively isolate the engine. Therefore, a heat-insulating and sound-proofing pad splicing mechanism is needed that can block the heat and sound emitted from the gap of the car heat-insulating and sound-proofing pad.
[0025] like Figure 1-2 As shown, the device includes a cushion body 1, a connecting mechanism 2 is arranged outside the cushion body 1, and an installation mechanism 3 is arranged outside the connecting mechanism 2. The gap between two cushion bodies 1 is connected by the connecting mechanism 2 to prevent heat from escaping from the gap, and the installation mechanism 3 can stack the two cushion bodies 1 to achieve better heat insulation and sound insulation effects.
[0026] First, the specific structure of the connecting mechanism 2 is disclosed. The connecting mechanism 2 includes a connecting sleeve 201. A mounting hole is opened inside the connecting sleeve 201. A connecting block 202 is arranged inside the mounting hole. A clamping member 203 is installed at the bottom of the connecting block 202. The clamping member 203 can clamp the bottom of the cushion body 1. A threaded column 204 is fixedly installed on the top of the connecting block 202. A fixing sleeve 205 is threadedly connected to the outer surface of the threaded column 204. The fixing sleeve 205 is attached to the top of the connecting sleeve 201. The fixing sleeve 205 and the clamping member 203 clamp and connect the two cushion bodies 1 inside the connecting sleeve 201.
[0027] Two cushion bodies 1 are provided, and the two cushion bodies 1 are butt-jointed inside the connecting sleeve 201 .
[0028] The clamping member 203 includes a connecting column 2031, which is fixedly installed at the bottom of the connecting block 202. A support plate 2032 is installed at the bottom of the connecting column 2031, and the support plate 2032 is attached to the bottom of the connecting sleeve 201. The connecting block 202 installed between the connecting column 2031 and the threaded column 204 can be placed and clamped to the sides of the two cushion bodies 1.
[0029] The threaded column 204 and the connecting column 2031 installed on the top and bottom of the connecting block 202 are inserted into the mounting hole of the connecting sleeve 201, and the abutment plate 2032 abuts against the bottom of the connecting sleeve 201. The sides of the two cushion bodies 1 are docked on both sides of the connecting block 202 inside the connecting sleeve 201, and then the fixing sleeve 205 is screwed on. The sides of the two cushion bodies 1 are docked inside the connecting sleeve 201 for fixed clamping, and the gap between the two cushion bodies 1 is filled, so as to achieve the effect of splicing the gap between the two cushion bodies 1, avoid the heat and sound emitted by the engine from emitting through the gap to affect the driver in the car, and soundproof and heat-insulate the engine in the front cabin of the car.

[0033] By installing the second fixing sleeve 3011 on the threaded column 204, when the two layers of the cushion body 1 are installed in a stacked manner, the second layer of the cushion body 1 is placed on both sides of the threaded column 204 in the connecting sleeve 201, and the second fixing sleeve 3011 is screwed on. The second layer of the cushion body 1 is clamped and fixed on the connecting sleeve 201 by the limiting rod 3012 on the second fixing sleeve 3011, and two limiting rods 3012 are provided, so that the two cushion bodies 1 on both sides of the threaded column 204 can be fixed and installed, thereby achieving the effect of fixing and installing the double-layer cushion body 1, so that the sound insulation and heat insulation pad is provided with multiple layers, and the sound insulation and heat insulation effects are better.
[0034] The improvement of this embodiment is that through the structure of the second fixing sleeve 3011 and the limiting rod 3012, the double-layer sound insulation and heat insulation pad can be fixedly installed, which solves the problem of the double-layer sound insulation and heat insulation pad being difficult to install and fix in the prior art.
[0035] In summary, the working principle of this solution is as follows:
