[0033] Please see Figure 2 and 3The utility model provides a protective door assembly, including a first door body 100 and a second door body 200. The first door body 100 and the second door body 200 can be relatively slidably arranged, and the first door body 100 and the second door body 200 can move towards or away from each other.

[0034] Please see Figure 3 and 4 A first bending structure 101 is provided on the inner side of the first door body 100 close to the second door body 200, and a second bending structure 201 is provided on the inner side of the second door body 200 close to the first door body 100. When the first door body 100 and the second door body 200 are closed, the first bending structure 101 and the second bending structure 201 are buckled together to form a sealing structure for covering the gap between the first door body 100 and the second door body 200.

[0035] Among them, the first bending structure 101 includes a first vertical plate 110 connected to the first door body 100 and a first baffle 120 and a second baffle 130 connected to the first vertical plate 110. It can be understood that the first vertical plate 110 is vertically installed at one end of the first door body 100 close to the second door body 200.

[0036] Please see Figure 3 and 4 The second bending structure 201 includes a second vertical plate 210 connected to the second door body 200 and a third baffle 220 connected to the second vertical plate 210. The first baffle 120 and the second baffle 130 are both located on the board surface on the same side of the first vertical plate 110 to form a mask space. Specifically, the first baffle 120, the second baffle 130 and the first vertical plate 110 enclose a mask space with an opening on one side. The opening on one side of the mask space is shielded by the second bending structure 201. The first vertical plate 110, the second door body 200 and the second bending structure 201 enclose a sealed rectangular inner cavity. It can be understood that the second vertical plate 210 is vertically installed on the second door body 200, and the spacing distance between the first vertical plate 110 and the second vertical plate 210 matches the length of the third baffle 220.

[0037] Please see Figure 3 and 4When the first door body 100 and the second door body 200 are closed, the third baffle 220 extends into the mask space, and the third baffle 220, the first vertical plate 110, the second door body 200 and the second vertical plate 210 enclose a sealed rectangular inner cavity, and the sealed rectangular inner cavity is located in the mask space. The first vertical plate 110, the second vertical plate 210, the second baffle 130, and the third baffle 220 form a first isolation cavity A, and a first interface A1 of the first isolation cavity A is formed between the third baffle 220 and the first vertical plate 110, and the first baffle 120 at least partially blocks the first interface A1 of the first isolation cavity A.

[0038] It can be understood that when the first door body 100 and the second door body 200 are opened, an operator can perform loading and unloading operations through the passage between the first door body 100 and the second door body 200.

[0039] Please see Figure 3 and 4 , the first baffle 120 and the second baffle 130 are spaced and arranged in parallel, and the first baffle 120 and the second baffle 130 are both vertically connected to the first vertical plate 110; the third baffle 220 is parallel to the first baffle 120 and the second baffle 130, and the third baffle 220 is vertically connected to the second vertical plate 210. Thus, the first vertical plate 110, the second vertical plate 210, the second baffle 130, and the third baffle 220 form a first isolation cavity A, and at least part of the first baffle 120 blocks the first interface A1 of the first isolation cavity A.

[0040] When the first door body 100 and the second door body 200 are closed, the third baffle plate 220 abuts against the first vertical plate 110 to form the first interface A1 of the first isolation chamber A. It can be understood that the first baffle plate 120 blocks the first interface A1, thereby preventing cutting fluid from entering the first isolation chamber A from the first interface A1.

[0041] Please see Figure 4 The protective door assembly also includes a first stopper plate 140, which is fixed to the end of the second baffle plate 130 and extends toward the first baffle plate 120. The second baffle plate 130 is abutted against the second vertical plate 210 through the first stopper plate 140. By setting the stopper plate, the cutting fluid entering the first isolation chamber A can be better prevented from entering the second isolation chamber B from the second interface B1.

[0042] The second vertical plate 210 is spaced apart from one end of the second door body 200 close to the first door body 100, and the second baffle 130, the first vertical plate 110, the second door body 200 and the second vertical plate 210 enclose a second isolation chamber B, and the first interface A1 of the first isolation chamber A is close to the first vertical plate 110, and the second interface B1 between the first isolation chamber A and the second isolation chamber B is close to the second vertical plate 210. When the second door body 200 and the first door body 100 are closed, the third baffle 220 abuts against the first vertical plate 110, and the third baffle 220 at least partially blocks the second interface B1. The first isolation chamber A can be formed by the third baffle 220, so that the cutting fluid remains in the first isolation chamber A, thereby sealing and protecting the second interface B1 well.

[0043] By staggeredly arranging the first interface A1 and the second interface B1 on the back of the first door body 100 and the second door body 200, cutting fluid from multiple directions can be prevented from escaping from the machine tool through the first interface A1 and the second interface B1, thereby ensuring the sealing of the machine tool protective door assembly.

[0044] Please see Figure 4 The protective door assembly also includes a second stop plate 230, which is fixed to the inner side of the second door body 200 close to the first door body 100 and extends toward the second baffle 130. The second stop plate 230 is closer to the first vertical plate 110 than the second vertical plate 210. When the third baffle 220 abuts against the first vertical plate 110, the second stop plate 230 abuts against the first vertical plate 110.

[0045] When the first door body 100 and the second door body 200 are closed, the first interface A1 of the first isolation cavity A and the third interface B2 of the second isolation cavity B away from the first isolation cavity A are both close to the first vertical plate 110. Since the first baffle 120 is fixedly installed on the first vertical plate 110, the first baffle 120 can better cover the first interface A1 and the third interface B2.

[0046] The second isolation chamber B is away from the third interface B2 of the first isolation chamber A and close to the first vertical plate 110, and at least part of the first baffle 120 also blocks the third interface B2 of the second isolation chamber B close to the first vertical plate 110. In this way, the third interface B2 can be blocked by the first baffle 120 and the surrounding wall of the first isolation chamber A, thereby ensuring the sealing between the first door body 100 and the second door body 200 when closed, thereby improving the waterproof performance of the protective door assembly.

[0047] Please see Figure 4The protective door assembly also includes a buffer seal 240, which is arranged between the first vertical plate 110 and the third baffle plate 220; and / or, the buffer seal 240 is arranged between the second baffle plate 130 and the second vertical plate 210. For example, the buffer seal 240 can be a waterproof rubber, which can improve the waterproofness between the first vertical plate 110 and the third baffle plate 220, and can also improve the waterproofness between the second baffle plate 130 and the second vertical plate 210.

[0048] The above-mentioned protective door assembly is provided with a first door body 100 and a second door body 200, wherein the first door body 100 and the second door body 200 can be relatively slidably arranged, and a first bending structure 101 is arranged on the inner side of the first door body 100 close to the second door body 200, and a second bending structure 201 is arranged on the inner side of the second door body 200 close to the first door body 100, wherein the first bending structure 101 includes a first vertical plate 110 connected to the first door body 100 and a first baffle 120 and a second baffle 130 connected to the first vertical plate 110, and the second bending structure 201 includes a second vertical plate 210 connected to the second door body 200 and a second baffle 120 and a second baffle 130 connected to the second vertical plate 210. There are three baffles 220, wherein the first baffle 120 and the second baffle 130 are both located on the board surface on the same side of the first vertical board 110 to form a mask space; when the first door body 100 and the second door body 200 are closed, the third baffle 220 extends into the mask space, and the first vertical board 110, the second vertical board 210, the second baffle 130, and the third baffle 220 form a first isolation cavity A, and a first interface A1 of the first isolation cavity A is formed between the third baffle 220 and the first vertical board 110, and the first baffle 120 at least partially blocks the first interface A1 of the first isolation cavity A, thereby improving the waterproof effect of the protective door assembly through the first baffle 120 and the first isolation cavity A.
