[0025] Specifically, in use, the first door 12 and the second door 15 are installed in the slots 11 opened on the frame 1. Then, the insert 13 at the end of the first door 12 is inserted into the slot 16 on the second door 15 to fix the first door 12 and the second door 15. When maintenance is required, the first door 12 and the second door 15 are separated, so that the insert 13 on the first door 12 is disengaged from the slot 16 on the second door 15. Then, the first door 12 and the second door 15 are slid to the top on the frame 1 to separate them. Then, the slide rod 24 in the fixing assembly 100 is pushed inward and inserted into the through slot 20 opened on the frame 1 to fix the first door 12 and the second door 15 at both ends of the frame 1.

[0026] In the above scheme, the first door 12 and the second door 15 are fixed by the frame 1. The plug 13 on the first door 12 is inserted into the slot 16 on the second door 15 to close the first door 12 and the second door 15. The first door 12 and the second door 15 are fixed by the fixing component 100 during maintenance. The first door 12 and the second door 15 are fixed in the normally open state by the slide rod 24 in the fixing component 100. The slide rod 24 is driven by the slide plate 23 on the slide rod 24 to unlock or fix the slide rod 24 in the first door 12 and the second door 15. The slide rod 24 is inserted into the through groove 20 when the first door 12 and the second door 15 are fixed.

[0027] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, side plates 21 are symmetrically arranged on the first door body 12 and the second door body 15. A predetermined gap is left between the two side plates 21 to form a slide groove 22, and the slide plate 23 is slidably arranged in the slide groove 22.

[0028] Specifically, the first door 12 and the second door 15 are unlocked from both sides of the frame 1, and the slide plate 23 is pulled to slide upward in the groove 22 between the side plates 21, thereby unlocking the first door 12 and the second door 15 from the frame 1.

[0029] As a further embodiment provided by this utility model, according to Figure 2 As shown, a predetermined gap is left between the slide plate 23 and the first door body 12 or the second door body 15 to form a placement groove 25, and a plurality of second elastic members 26 arranged in a linear array are provided in the placement groove 25.

[0030] Specifically, in the default state, multiple second elastic elements 26 release the elastic elements, push the slide plate 23 against it, and fix the first door 12 and the second door 15 onto the frame 1.

[0031] As a further embodiment provided by this utility model, according to Figure 2 As shown, the first door body 12 and the second door body 15 are provided with fixing bolts 28, which are located in the placement groove 25, and the slide plate 23 is provided with a hole groove 27.

[0032] Furthermore, the fixing bolt 28 has a threaded groove 29, and a screw 30 is movably disposed in the hole groove 27. The screw 30 passes through the hole groove 27 and is fixed in the threaded groove 29. A nut 31 is provided on the screw 30.

[0033] Specifically, when the first door body 12 and the second door body 15 are fixed to both ends of the frame 1, the nut 31 is turned to drive the screw 30 through the hole groove 27 into the threaded groove 29. The nut 31 is tightened, causing the screw 30 to move in the threaded groove 29, pushing the slide plate 23 inward and inserting the slide rod 24 into the through groove 20. At this time, the second elastic element 26 is under force. When unlocking, the nut 31 is loosened, causing the slide plate 23 to drive the slide rod 24 to move upward. At the same time, after the screw 30 is unlocked in the threaded groove 29, the second elastic element 26 releases force, unlocking the first door body 12 and the second door body 15.

[0034] As a further embodiment provided by this utility model, according to Figure 2 As shown, clamping plates 17 are symmetrically arranged inside the slot 16. A predetermined gap is left between the clamping plates 17 and the inner wall of the slot 16 to form a placement cavity 18. Multiple first elastic members 19 arranged in a linear array are arranged inside the placement cavity 18. A sealing block 14 is provided on the insert block 13.

[0035] Specifically, when the insert 13 is inserted into the slot 16, it will be pushed by the clamp 17. After the clamp 17 is pushed by the first elastic member 19, it fixes the insert 13 in the slot 16 and seals and fixes the first door body 12 and the second door body 15.

[0036] Working principle: The first door 12 and the second door 15 are installed in the slots 11 opened on the frame 1. Then, the insert 13 at the end of the first door 12 is inserted into the slot 16 on the second door 15, fixing the first door 12 and the second door 15. When maintenance is required, the first door 12 and the second door 15 are separated, allowing the insert 13 on the first door 12 to disengage from the slot 16 on the second door 15. Then, the door 12 is slid to its apex on the frame 1, separating the first door 12 and the second door 15. When the two doors 15 are fixed at both ends of the frame 1, rotating the nut 31 causes the screw 30 to pass through the slot 27 and enter the threaded slot 29. Tightening the nut 31 causes the screw 30 to move within the threaded slot 29, pushing the slide plate 23 inward and inserting the slide rod 24 into the through slot 20. At this time, the second elastic element 26 is under force. Then, the slide rod 24 in the fixing assembly 100 is pushed inward and inserted into the through slot 20 on the frame 1, fixing the first door 12 and the second door 15 at both ends of the frame 1. When unlocking, loosening the nut 31 causes the slide plate 23 to move the slide rod 24 upward. At the same time, after the screw 30 is unlocked within the threaded slot 29, the second elastic element 26 releases its force, unlocking the first door 12 and the second door 15.
