[0027] The following is combined with Figure 1 —6 Provide further details of this application.

[0028] The embodiment of the present application discloses an equipment maintenance door with strong sealing performance and easy installation.

[0029] Reference Figure 1 and Figure 2 A equipment maintenance door with strong sealing performance and easy installation, comprising a door frame 1, two symmetrical door hinges 3 are fixed on one side of the door frame 1, a door body 2 is arranged on the door frame 1, one side of the door body 2 is fixedly connected to the side of the two door hinges 3 away from the door frame 1, a sealing strip 4 is fixed on the door frame 1, a water retaining strip 5 is fixed on the door frame 1, an observation window 6 is fixed on the door body 2, two symmetrical fixing buckles 8 are fixed on the side of the door frame 1 away from the door hinge 3, two symmetrical fixing bolts 9 are rotatably connected to the side of the door body 2 away from the door hinge 3, and a resistance sealing mechanism 7 is arranged on the door body 2.

[0030] When using the equipment to inspect the door, first fix the door frame 1 to the corresponding door opening, then use the door hinge 3 to install the door body 2 on the door frame 1, and when closing the door body 2, directly let the door body 2 rotate under the support of the door hinge 3, let the door body 2 contact the sealing strip 4 on the door frame 1, and then let the fixing bolt 9 on the door body 2 be inserted into the fixing buckle 8 on the door frame 1 to complete the closing of the door body 2. The sealing strip 4 and the water retaining strip 5 between the door body 2 and the door frame 1 play a sealing role. The through window on the door body 2 can penetrate to the other side of the door body 2, and finally use the contact The sealing mechanism 7 moves on the door body 2, allowing the contact sealing mechanism 7 to contact the edge of the door frame 1 from the edge of the door body 2, allowing the contact sealing mechanism 7 to further contact and seal the gap between the door body 2 and the door frame 1. By closing the door body 2 and allowing the door body 2 to contact the sealing strip 4 on the door frame 1, the contact sealing mechanism 7 is moved on the door body 2, allowing the contact sealing mechanism 7 to contact the inner side of the door frame 1, thereby further sealing the door body 2 and the door frame 1, thereby improving the sealing performance of the inspection door, reducing the gap between the door body 2 and the door frame 1, and improving safety in use.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The contact sealing mechanism 7 includes two contact plates 71 symmetrically arranged on both sides of the door body 2. A movable groove 73 is opened on the side of the door body 2. The contact plate 71 is located in the contact groove and is slidably connected to the door body 2. A contact rubber strip 72 is fixed on the contact plate 71. A moving component 74 is arranged between the contact plate 71 and the door body 2. A vertical sealing component 75 is arranged on the door body 2.

[0032] After the door body 2 and the door frame 1 are put together, the moving assembly 74 is directly used to push the contact plate 71 to make the contact plate 71 slide in the movable groove 73, and the contact plate 71 drives the contact rubber strip 72 to contact the edge of the door frame 1, and the contact rubber strip 72 blocks the side gap between the door body 2 and the door frame 1. When the contact plate 71 moves, the contact plate 71 drives the vertical sealing assembly 75, and the vertical sealing assembly 75 blocks the gaps at the upper and lower ends of the door frame 1 and the door body 2. After the door body 2 and the door frame 1 are put together and the door body 2 contacts the sealing strip 4 on the door frame 1, the contact plate 71 is used to drive the contact rubber strip 72 to seal the side gap between the door body 2 and the door frame 1, and then the contact plate 71 drives the vertical sealing assembly 75 to seal the gaps at the upper and lower ends of the door body 2 and the door frame 1. Therefore, after the door body 2 contacts the sealing strip 4 on the door frame 1, the sealing effect between the door frame 1 and the door body 2 is further improved, thereby further improving the safety of the inspection door.

[0033] Reference Figure 4 and Figure 5 The moving assembly 74 includes a moving gear 742 rotatably connected to the door body 2, and two symmetrical moving racks 741 are slidably connected to the door body 2. The two moving racks 741 are fixedly connected to the corresponding contact plate 71, and the two moving racks 741 are staggered with each other. The two moving racks 741 are meshed with the moving gear 742. A rotating disk 743 is rotatably connected to the door body 2, and the rotating disk 743 is fixedly connected to the moving gear 742. A fixing member 744 is arranged between the rotating disk 743 and the door body 2.

[0034] After the door body 2 is closed on the door frame 1, the rotating disk 743 is directly rotated to allow the rotating disk 743 to drive the moving gear 742 to rotate, and the moving gear 742 drives the moving rack 741. The moving rack 741 slides under the limit of the door body 2, so that the moving rack 741 pushes the contact plate 71, and the contact plate 71 drives the contact rubber strip 72 to contact the inner wall of the door frame 1. By directly rotating the moving gear 742, the moving gear 742 drives the moving rack 741, and the moving rack 741 pushes the contact plate 71, so that after the door body 2 and the door frame 1 are closed, the contact plate 71 can be easily moved in the movable groove 73.

[0035] Reference Figure 1 and Figure 5 The fixing member 744 includes a plurality of fixing holes 7441 which are circumferentially distributed and opened on the rotating disk 743 . The fixing holes 7441 penetrate the rotating disk 743 . A fixing threaded rod 7442 is threadedly connected to the door body 2 . The fixing threaded rod 7442 penetrates one of the fixing holes 7441 .

[0036] When rotating the rotating disk 743, first separate the fixed threaded rod 7442 from the door body 2, and when the rotating disk 743 drives the moving gear 742, the moving gear 742 drives the moving rack 741, and the moving rack 741 pushes the contact plate 71, insert the fixed threaded rod 7442 into the fixed hole 7441 corresponding to the rotating disk 743, and then make the fixed threaded rod 7442 threadedly connected with the door body 2 to fix the rotating disk 743. By fixing the rotating disk 743 with the fixed threaded rod 7442, the contact plate 71 can be kept stable when the contact rubber strip 72 on the contact plate 71 contacts the door frame 1.

[0037] Reference Figure 2 , Figure 3 and Figure 6The vertical sealing assembly 75 includes two contact plates 751 symmetrically arranged at the upper and lower ends of the door body 2. The two contact plates 751 are located in the movable groove 73 and are slidably connected to the door body 2. A contact rubber strip 752 is fixed on the two contact plates 751. Support inclined blocks 753 are fixed at both ends of the contact plate 751. Pushing inclined blocks 754 are fixed at both ends of the contact plate 1 71. The inclined surface of the pushing inclined block 754 conflicts with the inclined surface of the supporting inclined block 753. An auxiliary contact member 755 is provided on the supporting inclined block 753.

[0038] When the moving rack 741 pushes the contact plate 1 71 and the contact plate 1 71 drives the contact rubber strip 1 72 to contact the door frame 1, the contact plate 1 71 drives the pushing inclined block 754 to push the inclined block 754 to slide on the supporting inclined block 753, so that the supporting inclined block 753 pushes the contact plate 2 751, and the contact plate 2 751 drives the contact rubber strip 2 752, so that the contact rubber strip 2 752 blocks the upper and lower ends of the gap between the door frame 1 and the door body 2. When the contact plate 1 71 moves, the pushing inclined block 754 on the contact plate 1 71 pushes the supporting inclined block 753, so that the supporting inclined block 753 drives the contact plate 2 751, and the contact plate 2 751 drives the contact rubber strip 2 752 to contact the inner walls at the upper and lower ends of the door frame 1, thereby further improving the sealing of the door body 2 closed on the door frame 1 and improving the safety of use.

[0039] Reference Figure 2 and Figure 3 The auxiliary resistance member 755 includes a push rod 7552 slidably connected to the supporting inclined block 753 , the push rod 7552 penetrates the supporting inclined block 753 , and a resistance rubber block 7551 is fixed to one end of the push rod 7552 away from the pushing inclined block 754 .

[0040] When the contact plate 71 drives the contact bevel block to slide on the supporting bevel block 753, the contact bevel block directly contacts the push rod 7552, allowing the push rod 7552 to slide on the supporting bevel block 753, allowing the push rod 7552 to push the contact rubber block 7551, allowing the contact rubber block 7551 and the contact rubber strip 72 on the contact plate 71 to contact the inner wall of the door frame 1 together; when the pushing bevel block 754 moves, the pushing bevel block 754 pushes the push rod 7552, allowing the push rod 7552 to push the contact rubber block 7551, allowing the contact rubber block 7551 and the contact rubber strip 72 to contact the door frame 1 together, thereby further sealing the gap between the door frame 1 and the door body 2.

[0041] Reference Figure 2 and Figure 3The end of the push rod 7552 away from the abutting rubber block 7551 is semicircular and corresponds to the push inclined block 754. When the push inclined block 754 slides on the supporting inclined block 753, the inclined surface of the push inclined block 754 abuts against the semicircular end of the push rod 7552, and then the push inclined block 754 pushes the push rod 7552. By making the end of the push rod 7552 close to the abutting inclined block semicircular, it is convenient to make the abutting inclined block abut the push rod 7552, reducing the possibility of the push rod 7552 getting stuck on the push inclined block 754.

[0042] Reference Figure 2 and Figure 6 The door body 2 has pulling grooves 756 at both ends, and reset springs 757 are arranged in the two pulling grooves 756. Both ends of the reset springs 757 are fixedly connected to the second contact plate 751 and the door body 2. When the support inclined block 753 supports the second contact plate 751 to approach the door frame 1, the second contact plate 751 directly pulls the reset springs 757. When the contact plate 1 71 drives the contact inclined block to reset, the reset springs 757 directly pull the second contact plate 751 to reset the second contact plate 751. By limiting the second contact plate 751 with the reset springs 757, the possibility that the second contact plate 751 does not reset and affects the opening and closing of the door body 2 can be reduced.

[0043] Working principle: When using the equipment to repair the door, first fix the door frame 1 on the corresponding door opening, and then use the door hinge 3 to install the door body 2 on the door frame 1. When closing the door body 2, directly let the door body 2 rotate under the support of the door hinge 3, let the door body 2 contact the sealing strip 4 on the door frame 1, and then let the fixing bolt 9 on the door body 2 be inserted into the fixing buckle 8 on the door frame 1 to complete the closing of the door body 2. The sealing strip 4 and water retaining strip 5 between the door body 2 and the door frame 1 play a sealing role, and the through window on the door body 2 can penetrate to the other side of the door body 2.

[0044] After the door body 2 is closed on the door frame 1, the rotating disk 743 is directly rotated to allow the rotating disk 743 to drive the moving gear 742 to rotate, and the moving gear 742 drives the moving rack 741, and the moving rack 741 slides under the limit of the door body 2, so that the moving rack 741 pushes the contact plate 1 71, and the contact plate 1 71 drives the contact rubber strip 1 72 to contact the inner wall of the door frame 1, and the contact plate 1 71 drives the contact rubber strip 1 72 to contact the door frame 1, while the contact plate 1 71 drives the pushing inclined block 754, and the inclined block 754 slides on the supporting inclined block 753, and the supporting inclined block 753 pushes the contact plate 2 751, and the contact plate 2 751 drives the contact rubber strip 2 752, and the contact rubber strip 2 752 blocks the gaps at the upper and lower ends of the door frame 1 and the door body 2.

[0045] When the contact plate 71 drives the contact bevel block to slide on the supporting bevel block 753, the contact bevel block directly contacts the push rod 7552, allowing the push rod 7552 to slide on the supporting bevel block 753, allowing the push rod 7552 to push the contact rubber block 7551, allowing the contact rubber block 7551 and the contact rubber strip 72 on the contact plate 71 to contact the inner wall of the door frame 1 together, and finally insert the fixed threaded rod 7442 into the fixed hole 7441 corresponding to the rotating disk 743, and then allow the fixed threaded rod 7442 to be threadedly connected to the door body 2, so that the rotating disk 743 is fixed, and the sealing between the door body 2 and the door frame 1 is completed.
