Description

Technical Field

[0001] This invention relates to the field of armored door technology, specifically to a high airtight door frame for intelligent armored doors and its processing equipment. Background Technology

[0002] Intelligent armored doors, as a high-end entrance door product integrating anti-theft, fireproofing, sound insulation, and heat preservation, have been widely used in civil and commercial buildings in recent years. The door frame, as the load-bearing structure and sealing interface of the door leaf, directly affects the overall sound insulation, heat preservation, dustproofing, and waterproofing performance of the door.

[0003] In existing technologies, smart armored doors typically employ a single-seal structure for their frames, meaning a sealing strip is placed on the contact surface between the door frame and the door leaf. While this structure is simple and low-cost, it suffers from the following drawbacks during long-term use: Single sealing performance is easy to degrade: The single-seal structure relies on only one sealing strip to achieve a seal. When the gap between the door frame and the door leaf changes due to temperature difference, installation settlement or long-term opening and closing, the compression of the sealing strip changes and the airtightness decreases significantly.

[0004] Lack of dynamic compensation capability: Most of the existing door frame sealing strips are fixed installations and cannot be adaptively adjusted according to changes in gaps, making it difficult to maintain stable airtight performance over a long period of time.

[0005] Sealing strips are susceptible to contamination and damage: The contact surface between the door frame and the door leaf is directly exposed to the external environment, and impurities such as dust and sand can easily adhere to the surface of the sealing strip, accelerating its aging and wear, and further reducing the sealing effect.

[0006] Low assembly efficiency and difficulty in ensuring accuracy: The structure of high airtight door frames is usually quite complex. The assembly of the inner and outer frames relies heavily on manual operation, which results in problems such as poor fitting accuracy, low assembly efficiency, and easy damage to sealing components.

[0007] To address the aforementioned problems, some improvements have been made in existing technologies, such as installing multiple sealing strips on the door frame or using a hollow structure to enhance thermal insulation performance. However, most of these solutions still suffer from drawbacks such as complex structure, difficult assembly, and rapid degradation of sealing performance over time. Therefore, developing an intelligent armored door frame that achieves high airtightness, long-term stable sealing capability, and is easy to assemble efficiently, along with its dedicated processing equipment, has become an urgent technical problem to be solved in this field. Summary of the Invention

[0008] The purpose of this invention is to provide a high airtight door frame for intelligent armored doors and its processing equipment, so as to solve the problems mentioned in the background art.

[0009] The present invention provides a high airtight door frame for intelligent armored doors, comprising a wall-fixed outer frame, a retaining strip, a high airtight inner frame, a compensating seal, a thickened plate, and a thermal insulation cavity. The retaining strip on the wall-fixed outer frame is engaged with the retaining groove of the high airtight inner frame, and the compensating seal is installed on the high airtight inner frame. The internal space of the wall-fixed outer frame is divided into multiple thermal insulation cavities by the thickened plate.

[0010] Furthermore, the outer frame of the wall is an "L"-shaped hollow structure; the high airtightness inner frame is a three-step inner frame structure, and the compensation seal is provided at the upper sealing step surface of the high airtightness inner frame.

[0011] Furthermore, the high airtightness inner frame includes a three-step inner frame, a slot, an inner reinforcing plate, an upper sealing step surface, a middle sealing step surface, a lower sealing step surface, a hard sealing strip, a soft sealing strip, a compensation recess, and a dust-blocking platform. The back of the three-step inner frame is provided with a slot for assembly with the slot strip, and the inner reinforcing plate is integrally installed inside the three-step inner frame. The lower sealing step surface of the three-step inner frame is provided with a hard sealing strip, the middle sealing step surface of the three-step inner frame is provided with a soft sealing strip, and the upper sealing step surface of the three-step inner frame is provided with a dust-blocking platform, forming the compensation recess. The compensation sealing element is installed in the compensation recess of the upper sealing step surface.

[0012] Furthermore, the three-step inner frame has a stepped structure, and its surface forms the upper sealing step surface, the middle sealing step surface and the lower sealing step surface. The lower sealing step surface is close to the ground and has an angle greater than 90 degrees with the horizontal plane. The upper sealing step surface is far from the ground. The upper sealing step surface and the middle sealing step surface are perpendicular to the horizontal plane.

[0013] Furthermore, the compensating seal includes a sealing part, a hard sealing part, and a compensating spring. The sealing part and the hard sealing part are integrally formed, and the hard sealing part is elastically slidably installed in the compensating recess by the compensating spring.

[0014] Furthermore, the sealing part is located below the dust-blocking platform, the dust-blocking platform is located above the opening of the compensation recess, the opening of the compensation recess is funnel-shaped, and the inner wall of the opening of the compensation recess is in close contact with the surface of the sealing part.

[0015] High airtightness door frame processing equipment includes a processing platform, support legs, a locking hydraulic cylinder, a limiting cylinder, a limiting end plate, a push plate, outer frame positioning strips, an inner frame placement platform, an inner frame horizontal limiter, an inner frame vertical limiter, and positioning protrusions. The processing platform is fixedly installed above the support legs, which are fixed to the ground. The locking hydraulic cylinder and the limiting cylinder are respectively installed at both ends of the processing platform. The limiting end plate is installed at the output end of the limiting cylinder, and the push plate is installed at the output end of the locking hydraulic cylinder. Two outer frame positioning strips are symmetrically installed on the upper surface of the processing platform. The positioning protrusions are provided on the end face of the inner frame placement platform installed on the upper surface of the processing platform. The inner frame horizontal limiter and the inner frame vertical limiter are installed on the processing platform.

[0016] Furthermore, the inner frame horizontal limiter includes a support plate, a pressing cylinder, a synchronization plate, a roller frame, and horizontal rollers. The support plate is vertically fixedly installed on the upper surface of the processing platform, and an inner frame vertical limiter fixing seat is installed on the side of the processing platform. The output ends of several pressing cylinders installed on the support plate are connected to the synchronization plate, and several horizontal rollers are rotatably installed on the roller frame installed on the synchronization plate.

[0017] Furthermore, the inner frame vertical limiter includes a fixed base, a drive shaft, a control motor, a lower pressure frame, a mounting groove, and vertical rollers. Two fixed bases are symmetrically fixed on the sides of the processing platform, and the drive shaft is rotatably mounted between the two fixed bases. The drive shaft is connected to the output end of the control motor mounted on one of the fixed bases. The lower pressure frame is fixedly mounted on the drive shaft, and the vertical rollers are rotatably mounted in the mounting groove of the lower pressure frame. The inner frame horizontal limiter and the inner frame vertical limiter are both mounted on both sides of the inner frame placement platform.

[0018] Furthermore, the inner frame placement platform has an "L" shaped structure. The inner frame placement platform is located away from the locking hydraulic cylinder and has a positioning protrusion on its end face near the limiting cylinder. The two outer frame positioning strips installed on the surface of the processing platform are parallel to each other and are located at one end of the inner frame placement platform, between the limiting cylinder and the positioning protrusion. The locking hydraulic cylinder can drive the push plate to move along the length direction of the inner frame placement platform and is parallel to the axis of the outer frame positioning strip. The push plate does not interfere with other structures.

[0019] A method for assembling a high-airtightness door frame for a smart armored door using processing equipment includes the following steps: S1: Place the high airtightness inner frame as claimed in the claim inside the L-shaped inner frame placement platform; S2: The wall fixing frame in the claim is placed on the processing platform, and the wall fixing frame is limited by the two outer frame positioning strips. At the same time, the opening of the heat insulation cavity formed by the wall fixing frame engages with the positioning protrusion provided on the end face of the inner frame placement table. S3: Activate the limiting cylinder, the inner frame horizontal limiter, and the inner frame vertical limiter. The limiting cylinder drives the limiting end plate to move towards the wall-fixed outer frame and makes contact with the end face of the wall-fixed outer frame for limitation. At the same time, the inner frame horizontal limiter makes rolling contact with the stepped surface of the high airtight inner frame for limitation, and the inner frame vertical limiter makes rolling contact with the top surface of the high airtight inner frame for limitation. S4: Engage the hydraulic cylinder to drive the push plate forward, thereby moving the high airtight inner frame toward the wall-fixed outer frame; S5: The clips of the fixed outer frame of the wall are inserted into the slots of the high airtight inner frame until the two are fully assembled. Then the locking hydraulic cylinder, the inner frame horizontal limiter and the inner frame vertical limiter are reset. S6: The limiting cylinder is reset, and then the assembled wall fixing outer frame and high airtightness inner frame are removed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention employs a combination design of a three-step inner frame structure and a compensating seal to form a multi-level stepped sealing system. Specifically, the upper, middle, and lower steps are each equipped with a sealing strip of different hardness. The lower step has a hard sealing strip to initially block external dust and rainwater, the middle step has a soft sealing strip to achieve airtightness and sound insulation, and the upper step has a compensating seal for dynamic sealing. The three seals work together to form a "maze-like" sealing path, significantly extending the air permeation path and enabling the airtightness level to reach the highest national standard. Simultaneously, the compensating seal is elastically slidably installed in a compensating recess via a spring. When the gap between the door leaf and the door frame changes slightly due to temperature variations or long-term use, the spring automatically pushes the sealing part outward, maintaining a tight fit with the door leaf. This achieves dynamic adaptive compensation, effectively eliminating gap problems caused by door leaf deformation or installation settlement, ensuring stable sealing performance even after long-term use.

[0021] 2. This invention features targeted designs for dust protection and structural strength of the sealing component. A dust-blocking platform is provided above the compensation recess opening, which can effectively prevent dust, sand, and other impurities from entering the compensation recess, avoiding spring jamming or wear of the sealing part; the compensation recess opening is designed in a trumpet shape, making close contact with the sealing surface, further enhancing the dustproof effect and significantly extending the service life and reliability of the sealing component.

[0022] 3. The processing equipment provided by this invention achieves automated and precise assembly of door frames. This equipment integrates a locking hydraulic cylinder, a limiting cylinder, an inner frame horizontal limiter, and an inner frame vertical limiter. Through the coordinated action of multiple mechanisms, it replaces traditional manual operation, significantly improving assembly efficiency and accuracy. Specifically, the inner frame horizontal limiter uses a pressing cylinder to drive horizontal rollers, providing rolling contact and limiting on the stepped surface of the high-airtightness inner frame; the inner frame vertical limiter uses a control motor to drive vertical rollers, providing rolling contact and limiting on the top surface of the inner frame. This dual horizontal and vertical limiting ensures that the inner frame maintains the correct posture during insertion, avoiding skewing or jamming, and guaranteeing precise alignment of the locking strip and the locking groove. Simultaneously, both the horizontal and vertical rollers use rolling contact, preventing scratches or indentations on the inner frame surface while providing limiting, effectively protecting the precision-formed three-step surface and the sealing component mounting surface.

[0023] 4. This invention has significant advantages in assembly positioning accuracy and ease of operation. The outer frame positioning strip limits the positioning of the fixed outer frame against the wall, and the positioning protrusion engages with the opening of the insulation cavity to ensure the positional accuracy of the outer frame on the processing platform. The inner frame placement platform has an L-shaped structure that matches the shape of the inner frame, facilitating quick and accurate placement. The various positioning structures cooperate with each other to achieve precise positioning of the outer and inner frames before assembly, ensuring assembly consistency in mass production. Simultaneously, all functional modules are integrated into the processing platform, with hydraulic cylinders and pneumatic cylinders working together to automatically complete the entire assembly process through a preset program. Operators only need to load and unload materials, reducing operational difficulty and labor intensity. Attached Figure Description

[0036] As attached Figure 1 To be continued Figure 4 As shown: The high airtight door frame for the intelligent armored door of the present invention includes a wall-fixed outer frame A1, a retaining strip A2, a high airtight inner frame A3, a compensating sealing element A4, a thickened plate A5, and a thermal insulation cavity A6. The retaining strip A2 provided on the wall-fixed outer frame A1 is engaged with the retaining groove 32 of the high airtight inner frame A3. The compensating sealing element A4 is installed on the high airtight inner frame A3. The internal space of the wall-fixed outer frame A1 is divided into multiple thermal insulation cavities A6 by the thickened plate A5. Specifically, the wall-fixing outer frame A1 is an "L"-shaped hollow structure, which is formed by bending and welding high-strength steel plate with a wall thickness of 2.0mm to 3.0mm. It is bent at a right angle and is used for fixed installation at the door opening in the wall. The high airtightness inner frame A3 is a three-step inner frame structure, which is formed by extrusion and welding of aluminum alloy profiles. It has the characteristics of being lightweight and high-strength. The compensation seal A4 is provided at the upper sealing step surface 34 of the high airtightness inner frame A3. The compensation seal A4 is used to elastically fit with the door surface when the door is closed to achieve dynamic sealing compensation.

[0037] Specifically, the high airtightness inner frame A3 includes a three-step inner frame 31, a slot 32, an inner reinforcing plate 33, an upper sealing step surface 34, a middle sealing step surface 35, a lower sealing step surface 36, a hard sealing strip 37, a soft sealing strip 38, a compensation recess 39, and a dust-blocking platform 30. The three-step inner frame 31 is integrally formed from aluminum alloy through extrusion welding. The slot 32 is formed along the length of its back side. The slot 32 has a dovetail or T-shaped cross-section and is used to snap onto the clip A2 on the wall-fixed outer frame A1, enabling a detachable connection between the high airtightness inner frame A3 and the wall-fixed outer frame A1. The inner reinforcing plate 33 is integrally formed inside the three-step inner frame 31. This inner reinforcing plate 33 extends along the length of the three-step inner frame 31, dividing the internal cavity of the three-step inner frame 31 into multiple independent chambers, significantly enhancing the overall rigidity and deformation resistance of the three-step inner frame 31. A hard sealing strip 37 is embedded on the lower sealing step surface 36 of the frame 31. The hard sealing strip 37 is made of EPDM rubber with a Shore A70 to A80 hardness and is fixed to the lower sealing step surface 36 by a dovetail groove structure. A soft sealing strip 38 is embedded on the middle sealing step surface 35 of the three-step inner frame 31. The soft sealing strip 38 is made of foamed rubber with a Shore A20 to A30 hardness and is also fixed to the middle sealing step surface 35 by a dovetail groove structure. A dust blocking platform 30 is integrally formed on the upper sealing step surface 34 of the three-step inner frame 31. The dust blocking platform 30 extends along the length of the upper sealing step surface 34 and together with the upper sealing step surface 34, forms the compensation recess 39. The compensation recess 39 extends along the length of the upper sealing step surface 34 and is used to accommodate the compensation seal A4. The compensation seal A4 is installed in the compensation recess 39 of the upper sealing step surface 34.

[0038] Specifically, the three-step inner frame 31 has a stepped structure, with the lower sealing step surface 36, the middle sealing step surface 35, and the upper sealing step surface 34 sequentially formed along the height direction on its surface. The three steps are arranged in a stepped manner. The lower sealing step surface 36 is located at the bottom of the three-step inner frame 31, close to the ground. The angle between the lower sealing step surface 36 and the horizontal plane is set to 92° to 95°, forming an outwardly inclined guide slope to facilitate the drainage of rainwater and dust. The upper sealing step surface 34 is located at the top of the three-step inner frame 31, away from the ground. The upper sealing step surface 34 and the middle sealing step surface 35 are perpendicular to the horizontal plane, that is, both are vertical planes to ensure good adhesion to the door surface.

[0039] Specifically, the compensating seal A4 includes a sealing part 41, a hard sealing part 42, and a compensating spring 43. The sealing part 41 and the hard sealing part 42 are integrally injection molded from TPE or rubber material. The sealing part 41 is in the shape of a hollow bubble tube, which has good compression resilience. The hard sealing part 42 has a solid structure and is used to cooperate with the compensating spring 43. A spring mounting hole is opened at the bottom of the hard sealing part 42. The compensating spring 43 is a stainless steel compression spring, one end of which abuts against the bottom of the compensating recess 39, and the other end is inserted into the spring mounting hole of the hard sealing part 42. The hard sealing part 42 is elastically slidably installed in the compensating recess 39 by the compensating spring 43. The elastic force of the compensating spring 43 drives the sealing part 41 to always extend outward to maintain close contact with the door surface.

[0040] Specifically, the sealing part 41 is located below the dust blocking platform 30, that is, the dust blocking platform 30 covers the sealing part 41 in the vertical direction, forming a shielding structure; the dust blocking platform 30 is located above the opening of the compensation recess 39, and a gap of 0.5mm to 1.0mm is left between its lower surface and the upper surface of the sealing part 41, allowing the sealing part 41 to freely expand and contract under the action of the compensation spring 43; the opening of the compensation recess 39 is designed as a trumpet shape, that is, the opening gradually expands from the inside to the outside, and the inner wall of the trumpet-shaped opening forms a tight contact with the surface of the sealing part 41 when the sealing part 41 is extended, playing a dual role of auxiliary sealing and dust prevention, preventing dust, sand and other impurities from entering the interior of the compensation recess 39. Example

[0041] As attached Figure 5 To be continued Figure 9 As shown: The high airtightness door frame processing equipment of the present invention includes a processing platform B1, a support frame B2, a locking hydraulic cylinder B3, a limiting cylinder B4, a limiting end plate B5, a pushing plate B6, an outer frame positioning strip B7, an inner frame placement platform B8, an inner frame horizontal limiter B9, an inner frame vertical limiter B10, and a positioning protrusion B11. The processing platform B1 is fixedly installed above the support frame B2, and the support frame B2 is fixed to the ground. The locking hydraulic cylinder is installed at both ends of the processing platform B1. The machining platform B1 is equipped with cylinder B3 and limiting cylinder B4, wherein the output end of the limiting cylinder B4 is equipped with the limiting end plate B5, and the output end of the locking hydraulic cylinder B3 is equipped with the pushing plate B6; two outer frame positioning strips B7 are symmetrically installed on the upper surface of the machining platform B1, and the end face of the inner frame placement platform B8 installed on the upper surface of the machining platform B1 is provided with the positioning protrusion B11; the inner frame horizontal limiter B9 and the inner frame vertical limiter B10 are installed on the machining platform B1.

[0042] Specifically, the inner frame horizontal limiter B9 includes a support plate 11, pressing cylinders 12, a synchronization plate 13, a roller frame 14, and horizontal rollers 15. The support plate 11 is vertically fixed to the upper surface of the processing platform B1, using welding or bolt connections, and serves to support the components of the inner frame horizontal limiter B9. A fixing seat 21 for the inner frame vertical limiter B10 is installed on the side of the processing platform B1, and this fixing seat 21 is fastened to the side of the processing platform B1 by bolts. Several pressing cylinders 12 are horizontally mounted on the upper part of the support plate 11, and the output end of each pressing cylinder 12 is connected to a synchronization plate. The timing plate 13 is elongated and extends along the length of the inner frame placement platform B8. When the piston rod of the pressing cylinder 12 extends, it pushes the timing plate 13 to move closer to the inner frame placement platform B8. A roller frame 14 is fixedly installed on the timing plate 13. The roller frame 14 has multiple installation positions spaced along the length of the timing plate 13. A horizontal roller 15 is rotatably installed at each installation position. The horizontal roller 15 is made of polyurethane material. Its axis of rotation is perpendicular to the length of the inner frame placement platform B8. The wheel surface of the horizontal roller 15 is used to roll in contact with the stepped surface of the high airtight inner frame A3 to achieve horizontal limiting guidance.

[0043] Specifically, the inner frame vertical limiter B10 includes a fixed base 21, a drive shaft 22, a control motor 23, a lower pressure frame 24, a mounting groove 25, and a vertical roller 26. Two fixed bases 21 are symmetrically fixedly installed on both sides of the processing platform B1, facing each other. The drive shaft 22 is rotatably mounted between the two fixed bases, extending horizontally along the width direction of the processing platform B1. One end of the drive shaft 22 is connected to the output end of the control motor 23 mounted on one of the fixed bases 21 via a coupling. The control motor 23 is a servo motor or a stepper motor, used to precisely control the rotation angle of the drive shaft 22. The lower pressure frame 24 is fixedly mounted on the drive shaft 22, and the lower pressure frame 24 is L-shaped or U-shaped, following the movement of the drive shaft. 22 rotates synchronously; the end of the lower pressure frame 24 is provided with a mounting groove 25, in which the vertical roller 26 is rotatably mounted via a rotating shaft. The vertical roller 26 is made of polyurethane material, and its wheel surface is used to roll in contact with the top surface of the high airtight inner frame A3; when the control motor 23 drives the drive shaft 22 to rotate, the lower pressure frame 24 drives the vertical roller 26 to swing up and down, thereby pressing or releasing the top surface of the high airtight inner frame A3; the inner frame horizontal limiter B9 and the inner frame vertical limiter B10 are both installed on both sides of the inner frame placement platform B8, wherein the inner frame horizontal limiter B9 is located on one side of the inner frame placement platform B8 for limiting from the side, and the inner frame vertical limiter B10 is located on both sides above the inner frame placement platform B8 for limiting from above.

[0044] Specifically, the inner frame placement platform B8 has an "L"-shaped structure with a right-angle bend in its cross-section, matching the L-shaped back of the high-airtightness inner frame A3, and is used to support and position the high-airtightness inner frame A3. The end of the inner frame placement platform B8 furthest from the locking hydraulic cylinder B3, i.e., the end closest to the limiting cylinder B4, has a positioning protrusion B11 on its end face. This positioning protrusion B11 matches the shape of the opening of the thermal insulation cavity A6 on the wall-fixing outer frame A1, and is used to engage and position with the opening of the thermal insulation cavity A6. Two outer frame positioning strips B7 are installed parallel to each other on the surface of the processing platform B1, with the distance between them matching the width of the wall-fixing outer frame A1, and are used to limit the wall-fixing outer frame A1 on both sides. The two outer frame positioning strips B7 are located at one end of the inner frame placement platform B8. The area between the limiting cylinder B4 and the positioning protrusion B11 ensures that after the outer frame A1 of the wall is positioned, the opening of its thermal insulation cavity A6 is directly opposite the positioning protrusion B11. The piston rod of the locking hydraulic cylinder B3 extends in a direction parallel to the length direction of the inner frame placement platform B8. The locking hydraulic cylinder B3 can drive the push plate B6 to reciprocate linearly along the length direction of the inner frame placement platform B8. The movement direction of the push plate B6 is parallel to the axis of the outer frame positioning strip B7, ensuring that when the push plate B6 pushes the high airtight inner frame A3, the inner frame can be accurately pushed into the outer frame in a straight line. The width of the push plate B6 is smaller than the width of the inner frame placement platform B8, and the movement trajectory of the push plate B6 is above the inner frame placement platform B8, without interfering with other structures, ensuring smooth and unobstructed pushing action.

[0045] The method for assembling a high-airtightness door frame for a smart armored door according to the processing equipment includes the following steps: S1: Place the high airtight inner frame A3 of claim 1 inside the L-shaped inner frame placement platform B8; S2: Place the wall fixing frame A1 in claim 1 on the processing platform B1, limit the wall fixing frame A1 by the two outer frame positioning strips B7, and at the same time, the opening of the heat insulation cavity A6 formed by the wall fixing frame A1 engages with the positioning protrusion B11 provided on the end face of the inner frame placement platform B8 for positioning. S3: Activate the limiting cylinder B4, the inner frame horizontal limiter B9, and the inner frame vertical limiter B10. The limiting cylinder B4 drives the limiting end plate B5 to move towards the wall-fixed outer frame A1 and makes contact with the end face of the wall-fixed outer frame A1 for limitation. At the same time, the inner frame horizontal limiter B9 makes rolling contact with the stepped surface of the high airtight inner frame A3 for limitation, and the inner frame vertical limiter B10 makes rolling contact with the top surface of the high airtight inner frame A3 for limitation. S4: The hydraulic cylinder B3 is engaged, which drives the push plate B6 to move forward, thereby driving the high airtight inner frame A3 to move towards the wall-fixed outer frame A1. S5: The locking strip A2 of the fixed outer frame A1 of the wall is inserted into the slot 32 of the high airtight inner frame A3 until the two are fully assembled. Then the locking hydraulic cylinder B3, the inner frame horizontal limiter B9 and the inner frame vertical limiter B10 are reset. S6: The limiting cylinder B4 is reset, and then the assembled wall fixing outer frame A1 and high airtight inner frame A3 are removed.

[0046] First, the high airtight inner frame A3 is placed inside the L-shaped inner frame placement platform B8. The L-shaped cross-section of the inner frame placement platform B8 matches the shape of the back of the high airtight inner frame A3, which plays a supporting and initial positioning role for the high airtight inner frame A3.

[0047] Next, the wall fixing frame A1 is placed on the processing platform B1. Two parallel outer frame positioning strips B7 limit the wall fixing frame A1 from both sides. At the same time, the opening of the heat insulation cavity A6 of the wall fixing frame A1 engages with the positioning protrusion B11 on the end face of the inner frame placement platform B8, so that the wall fixing frame A1 is precisely fixed in both the horizontal and vertical directions.

[0048] Next, the limiting cylinder B4 is activated, which drives the limiting end plate B5 to move towards the wall-fixed outer frame A1. The limiting end plate B5 contacts the end face of the wall-fixed outer frame A1 and applies a limiting force to prevent the wall-fixed outer frame A1 from shifting during subsequent assembly. At the same time, the inner frame horizontal limiter B9 and the inner frame vertical limiter B10 are activated. The pressing cylinder 12 of the inner frame horizontal limiter B9 pushes the synchronous plate 13, causing the horizontal roller 15 to roll into contact with the stepped surface of the high airtight inner frame A3, thus limiting and guiding the high airtight inner frame A3 in the horizontal direction. The control motor 23 of the inner frame vertical limiter B10 drives the drive shaft 22 to rotate, which drives the lower pressure frame 24 to move, causing the vertical roller 26 to roll into contact with the top surface of the high airtight inner frame A3, thus limiting and guiding the high airtight inner frame A3 in the vertical direction.

[0049] Then, the locking hydraulic cylinder B3 is activated, which drives the push plate B6 to move forward along the length of the inner frame placement platform B8. The push plate B6 pushes the high airtight inner frame A3 toward the wall-fixed outer frame A1. Under the rolling limit guidance of the horizontal roller 15 and the vertical roller 26, the high airtight inner frame A3 maintains the correct posture and moves in a straight line.

[0050] Subsequently, as the high airtight inner frame A3 continues to move forward, the clip A2 set on the wall fixing outer frame A1 is gradually inserted into the slot 32 on the back of the high airtight inner frame A3. The dovetail or T-shaped section of the slot 32 forms a snap-fit ​​with the clip A2 until the high airtight inner frame A3 and the wall fixing outer frame A1 are completely assembled together.

[0051] Finally, the hydraulic cylinder B3, the inner frame horizontal limiter B9, and the inner frame vertical limiter B10 are reset, and the limit cylinder B4 is reset, allowing the assembled door frame to be removed from the processing equipment. When the door is closed, the hard sealing strip 37, the soft sealing strip 38, and the compensating seal A4 on the high airtight inner frame A3 sequentially contact the door surface. The compensating spring 43 of the compensating seal A4 automatically adjusts the extension of the sealing part 41 according to the gap between the door and the door frame, always maintaining a tight fit with the door surface, achieving multiple dynamic seals.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
