In the disassembly process of the perspective window, a force towards the clamping end 202 is applied to the insertion end 201 of the perspective window, and the perspective window can be separated from the mounting hole under the action of the external force. The perspective window is simple in structure, does not need additional mounting tools and dismounting tools, can be mounted and dismounted by only applying external force, reduces the mounting difficulty and the dismounting difficulty of the perspective window, and is beneficial to saving the production cost and the mounting cost.

It can be appreciated that the first sealing ring 300 is in interference fit with the hole wall of the mounting hole 101, and the first sealing ring 300 can be utilized to compress the insertion end 201 of the perspective window 200, so that the insertion end 201 is fixed in the mounting hole 101 in a sealing manner; the second sealing ring 400 is in interference fit with the hole wall of the mounting hole 101, and the second sealing ring 400 can be utilized to press the clamping end 202 of the perspective window, so that the clamping end 202 is fixed in the mounting hole 101 in a sealing manner.

It will be appreciated that the window is inserted into the mounting hole 101 in a first direction, with the snap-in end 202 of the window facing the insertion end 201 of the window. Accordingly, the mounting hole 101 is pulled out from the perspective window along a second direction, which is opposite to the first direction, and the second direction faces the clamping end 202 of the perspective window along the insertion end 201 of the perspective window.

In some embodiments, as shown in connection with fig. 2 and 4, the second circumferential groove 204 includes an inclined sidewall 2041 proximate to the insertion end 201, the inclined sidewall 2041 extending toward the side of the insertion end 201 to engage the second seal ring 400 to compress the viewing window 200.

At the same time, the sealing effect on the see-through window 200 can be improved.

In some embodiments, the second plate 104 is provided with a second through hole through which the second stepped portion 206 is adapted to pass, the second through hole having an inner diameter that is greater than the diameter of the second stepped portion 206.

So configured, the second step 206 is facilitated to pass through the second plate 104 and cooperate with the second seal ring 400 to secure and seal the second step 206. The second through hole has an inner diameter larger than that of the second stepped portion 206, so that the second stepped portion 206 is conveniently installed, the second stepped portion 206 smoothly passes through the second through hole, and the position of the perspective window 200 is conveniently adjusted.

In some embodiments, as shown in connection with fig. 4, the side of the second plate body 104 facing the first plate body 103 is provided with a support steel plate 106, and the support steel plate 106 is configured with a third through hole through which the second stepped portion is adapted to pass, the inner diameter of the third through hole being equal to the inner diameter of the second stepped portion 206.

Through setting up supporting steel plate 106, can support mounting hole periphery plate body and perspective window, avoid the sunken deformation of mounting hole periphery plate body, improve the reliability of the door body. The inner diameter of the third through hole is equal to the diameter of the second step part 206, which is favorable for limiting the second step part 206, and further prevents the second step part 206 from being installed askew.

The perspective window 200 is installed on the premise that the first plate 103, the second plate 104, and the supporting steel plate 106 are assembled and foamed. At this time, the first sealing ring 300 and the second sealing ring 400 are mounted on the transparent window 200, and then the assembly of the three is inserted into the mounting hole 101 of the assembly along the first direction, when the sealing ring passes through the aperture minimum portion, a proper force needs to be applied to pass through the sealing ring, and finally the assembly effect as shown in fig. 4 is achieved, that is, the transparent window 200 is clamped at a proper position due to the elastic action of the first sealing ring 300 and the second sealing ring 400 and cannot be flicked, so that the effects of quick and effective assembly and difficult looseness are achieved. The disassembly process is to apply a force to the perspective window 200 Shi Jiayan in the second direction to separate the perspective window from the mounting hole 101, so as to achieve the purpose of quick disassembly and replacement. The structure has the advantages of simple structure, lower cost and the like.
