Detailed Implementation

[0073] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0074] like Figures 1 to 8 As shown, this embodiment proposes a sealed door structure, including a door panel 1, a bottom plate 4, a sealing part, a first sealing plate 5, a second sealing plate 6, a fixing part, and a locking part. The door panel 1 is installed inside the door frame 3 via a hinge 2, and the bottom plate 4 is installed at the lower part of the door frame 3. The bottom plate 4 and the door panel 1 are in a sealing fit.

[0075] The sealing part is installed inside the door frame 3 and cooperates with the door plate 1 to seal the door plate 1, and comprises the side strip 7, the sealing seat one 8, the sealing strip one 9, the connecting block one 10, the third sealing plate 11 and a sealing assembly. The side strip 7 is provided with two, which are symmetrically installed on the inner side of the door frame 3. The sealing seat one 8 is installed inside each side strip 7. The sealing strip one 9 is provided with two, one end of which is installed in the sealing seat one 8. The through slot is formed on the side of each side strip 7 close to the door plate 1, and the connecting block one 10 is slidably arranged inside each through slot. One end of the connecting block one 10 is connected with the sealing strip one 9, and the third sealing plate 11 is installed at the other end of each connecting block one 10. The sealing assembly is installed on the inner top side of the door frame 3 to seal the door plate 1.

[0076] Specifically, when sealing through the sealing door, the door plate 1 is first pushed to rotate along the hinge 2. When the door plate 1 contacts the bottom plate 4, the door plate 1 drives the first sealing plate 5 to contact the sealing strip one 9. Since the sealing strip one 9 is tubular and has a certain elasticity, it deforms when contacting the first sealing plate 5. The deformation of the sealing strip one 9 pushes the connecting block one 10 to move, thereby pushing the third sealing plate 11 to move through the connecting block one 10, so that the third sealing plate 11 is in close contact with the first sealing plate 5. In this way, the cooperation between the first sealing plate 5, the third sealing plate 11 and the sealing strip one 9 improves the safety of sealing, and the cooperation with the sealing assembly further improves the tightness of sealing, reduces the leakage of gas and liquid, and improves the safety of the equipment that needs to be sealed.

[0077] The sealing assembly comprises the top plate 12, the sealing seat two 13, the sealing strip two 14, the connecting block two 15 and the fourth sealing plate 16.

The connecting block two 15 is slidably arranged inside the square slot and connected with the sealing strip two 14. The fourth sealing plate 16 is installed on the lower side of the connecting block two 15.

[0078] Specifically, when sealing, the door plate 1 pushes the second sealing plate 6 to contact the sealing strip two 14. Since the sealing strip two 14 is tubular and has a certain elasticity, it deforms when contacting the second sealing plate 6, thereby pushing the connecting block one 10 to move through the sealing strip two 14. The connecting block one 10 pushes the fourth sealing plate 16 to move, so that the fourth sealing plate 16 is in close contact with the second sealing plate 6, thereby further improving the tightness of sealing.

[0079] The first sealing plate 5 is installed on both sides of the door plate 1 and cooperates with the sealing part; the second sealing plate 6 is installed on the upper part of the door plate 1 and cooperates with the sealing part; the fixing part is installed on one side of the door frame 3 and is used for fixing the position of the door plate 1 and avoiding the vibration of the door plate 1, and the fixing part comprises a casing 17, fixing holes one 18, fixing holes two 19, a fixing rod 20, a push plate 21, a first spring 22 and a transmission assembly; the casing 17 is installed on one side of the door frame 3 and is provided with a plurality of fixing holes one 18 equidistantly on the side close to the door frame 3; the door frame 3 is provided with through holes corresponding to the fixing holes one 18; the door plate 1 is provided with a plurality of fixing holes two 19 on the side close to the casing 17, and the fixing holes two 19 correspond to the fixing holes one 18 respectively; the fixing rod 20 is slidably arranged in each fixing hole one 18; the push plate 21 is installed on the end of the fixing rod 20 away from the door plate 1; the first spring 22 is sleeved on each fixing rod 20; and the transmission assembly is installed in the casing 17 and is used for transmitting power.

[0080] Specifically, after the door plate 1 is sealed, the door plate 1 needs to be fixed, first, the transmission assembly is started, the push plate 21 is pushed to move through the transmission assembly, the fixing rod 20 is driven to move by the push plate 21, the fixing rod 20 moves along the direction of the fixing hole one 18, the fixing rod 20 passes through the through hole and enters the fixing hole two 19, and the relative position of the door plate 1 and the door frame 3 is fixed through the cooperation between the fixing rod 20 and the fixing hole one 18 and the fixing hole two 19, thereby solving the problem that the door plate 1 cannot be closed tightly or even cannot be closed, reducing the influence of external factors on the sealing performance of the door plate 1, and when the equipment is completed and the door plate 1 needs to be opened, the transmission assembly is started again, the transmission assembly is separated from the push plate 21, the push plate 21 is pushed by the first spring 22, the fixing rod 20 is driven to move by the push plate 21, and thus the fixing rod 20 is separated from the fixing hole two 19, and the door plate 1 can be opened.

[0081] The transmission assembly comprises a rack 23, a driving gear 24, a plurality of incomplete gears 25, a cam 26 and a push piece 27; the rack 23 is slidably arranged in the casing 17; the driving gear 24 is rotatably installed in the casing 17 and is engaged with the rack 23; the plurality of incomplete gears 25 are rotatably installed in the casing 17 and are engaged with the rack 23; the cam 26 is installed on each incomplete gear 25; and the push piece 27 penetrates the casing 17 and is connected with the driving gear 24.

[0082] Specifically, when the position of the door panel 1 needs to be fixed, first hold the push piece 27 and twist the push piece 27 to drive the driving gear 24 to rotate, and the rotation of the driving gear 24 drives the rack 23 to slide inside the shell 17, the sliding of the rack 23 drives the incomplete gear 25 to rotate, the rotation of the incomplete gear 25 drives the cam 26 to rotate, and the rotation of the cam 26 drives the push plate 21 to move, thereby fixing the position of the door panel 1 by the fixing part. When the door panel 1 needs to be opened, only the push piece 27 needs to be twisted in the opposite direction, so that the cam 26 returns to the original position, and the fixed rod 20 is separated from the fixed hole two 19 through cooperation with the first spring 22.

[0083] The locking part is installed on the other side of the door frame 3, used for cooperation with the sealing part to improve the sealing effect, and the locking part comprises a rack 28, a plurality of electric cylinders 29, locking holes 30, connecting holes 31, locking blocks 32 and positioning assemblies. The rack 28 is installed on the other side of the door frame 3, the plurality of electric cylinders 29 are equidistantly installed inside the rack 28, the door frame 3 is provided with the locking holes 30 corresponding to the electric cylinders 29, the rack 28 is provided with the connecting holes 31 corresponding to the locking holes 30, and the locking block 32 is slidably arranged inside each locking hole 30. The locking block 32 is connected with the output end of the electric cylinder 29, and the positioning assembly is installed inside the connecting hole 31 to improve the stability during locking.

[0084] Specifically, before fixing the position of the door panel 1, it is necessary to ensure that the first sealing plate 5, the second sealing plate 6 and the third sealing plate 11 are uniformly and tightly attached. First, start the electric cylinder 29 to drive the locking block 32 to move along the direction of the connecting hole 31. The locking block 32 is in contact with the door panel 1 through the locking hole 30. Since the locking block 32 is a tapered structure, the door panel 1 can be slowly pushed during the movement of the locking block 32, so that the first sealing plate 5 and the second sealing plate 6 are more tightly attached to the third sealing plate 11 and the third sealing plate 11, thereby further improving the tightness.

[0085] The above-mentioned positioning assembly comprises a positioning groove 33, a second spring 34 and a positioning block 35. Each connecting hole 31 is provided with a positioning groove 33, each positioning groove 33 is provided with a second spring 34, and each positioning groove 33 is slidably provided with a positioning block 35. The positioning block 35 is connected with the second spring 34, and the output end of each electric cylinder 29 is provided with a positioning hole corresponding to the positioning block 35.

[0086] Specifically, when the locking block 32 moves to the set position, the positioning block 35 in the positioning groove 33 is pressed into the positioning hole of the output end of the electric cylinder 29 under the pressure of the spring, thereby fixing the position of the locking block 32 and improving the stability of the sealing.

[0087] On the basis of the foregoing, the sealing door body is further provided, and the sealing door body comprises an observation window 36, a water baffle 37 and thermal insulation cotton 38.

[0089] In summary, when the sealing door is used, the door plate 1 is first pushed to rotate along the hinge 2, and when the door plate 1 contacts the bottom plate 4, the door plate 1 drives the first sealing plate 5 to contact the sealing strip one 9. Since the sealing strip one 9 is tubular and has a certain elasticity, the sealing strip one 9 deforms when it contacts the first sealing plate 5. The deformation of the sealing strip one 9 drives the connecting block one 10 to move, thereby driving the third sealing plate 11 to move through the connecting block one 10, so that the third sealing plate 11 tightly contacts the first sealing plate 5. In this way, the cooperation among the first sealing plate 5, the third sealing plate 11 and the sealing strip one 9 improves the safety of the sealing.

[0090] Furthermore, the second sealing plate 6 is driven by the door plate 1 to contact the sealing strip two 14. Since the sealing strip two 14 is tubular and has a certain elasticity, the sealing strip two 14 deforms when it contacts the second sealing plate 6, thereby driving the connecting block one 10 to move through the sealing strip two 14. The connecting block one 10 drives the fourth sealing plate 16 to move, so that the fourth sealing plate 16 tightly contacts the second sealing plate 6, thereby further improving the tightness of the sealing, reducing the leakage of gas and liquid, and improving the safety of the equipment that needs to be sealed.

[0091] Before fixing the position of the door plate 1, it is necessary to ensure that the first sealing plate 5, the second sealing plate 6 and the third sealing plate 11 are uniformly and tightly attached, first, the electric cylinder 29 is started, the locking block 32 is pushed to move by the electric cylinder 29, the locking block 32 moves along the direction of the connecting hole 31, the locking block 32 is in contact with the door plate 1 through the locking hole 30, since the locking block 32 is a tapered structure, the door plate 1 can be slowly pushed during the movement of the locking block 32, so that the first sealing plate 5 and the second sealing plate 6 driven by the door plate 1 are more tightly attached to the third sealing plate 11 and the third sealing plate 11, when the locking block 32 moves to the set position, the positioning block 35 in the positioning groove 33 is pressed into the positioning hole of the output end of the electric cylinder 29 under the pressure of the second spring 34, so that the position of the locking block 32 is fixed, and the stability and tightness of the sealing are improved.

[0092] After the door plate 1 is sealed, the door plate 1 needs to be fixed, first, hold the knob 27 and twist the knob 27, drive the driving gear 24 to rotate through the knob 27, drive the rack 23 to slide in the shell 17 through the rotation of the driving gear 24, drive the incomplete gear 25 to rotate through the sliding of the rack 23, drive the cam 26 to rotate through the rotation of the incomplete gear 25, drive the push plate 21 to move through the rotation of the cam 26, drive the fixing rod 20 to move through the movement of the push plate 21, the fixing rod 20 moves along the direction of the fixing hole one 18, the fixing rod 20 passes through the through hole and enters the fixing hole two 19, the relative position of the door plate 1 and the door frame 3 is fixed through the cooperation between the fixing rod 20 and the fixing hole one 18 and the fixing hole two 19, so that the problem that the door plate 1 cannot be tightly closed or even cannot be closed is solved, and the influence of external factors on the sealing performance of the door plate 1 is reduced.

[0093] When the equipment work is completed and the door plate 1 needs to be opened, only the knob 27 needs to be twisted in the reverse direction, so that the cam 26 returns to the original position, under the cooperation of the first spring 22, the first spring 22 pushes the push plate 21, the fixing rod 20 is driven to move through the push plate 21, so that the fixing rod 20 is separated from the fixing hole two 19, and the door plate 1 can be opened.

[0094] Through the setting of the water baffle 37, the impurities in the outside are separated, the tightness of the observation window 36 is ensured, through the setting of the thermal insulation cotton, the loss of the equipment during the working process can be reduced, and the influence of the temperature in the outside on the inside of the equipment can also be reduced.
