Description

Technical Field

[0001] The invention relates to the field of heat-insulating doors and windows, and in particular to a heat-insulating fireproof door and window sealing structure. Background Art

[0002] With the vigorous development of the construction industry, the requirements for the performance of doors and windows in different buildings are becoming more and more diverse; in ordinary building scenes, such as residential houses and conventional commercial buildings, cost is a key factor in the design and selection of doors and windows; on the basis of meeting the basic functions of wind and rain protection, lighting and ventilation, and fire protection and insulation, cost control can improve the product's cost performance and meet the public's economic expectations, so affordable door and window products are more popular.

[0003] However, in special places, the situation is completely different and cost is not the primary consideration.

[0004] For example, the fireproof doors and windows of a safe have a heavy responsibility. Not only must they have anti-theft and anti-destruction properties to protect valuables in the safe from theft and external damage, they must also build a safety line for the items in a fire to ensure that they remain intact.

[0005] To meet these special needs, the glass of fire-resistant doors and windows in these places is relatively firm during installation; but this also brings great difficulties to subsequent maintenance. Conventional disassembly methods and disassembly equipment are difficult to quickly disassemble such door and window glass; in actual work, maintenance personnel often have to spend a lot of time studying disassembly plans, and even need to use special large equipment, which not only reduces maintenance efficiency and increases costs, but also faces huge challenges in emergency situations; once the glass of fire-resistant doors and windows is suddenly damaged, its fire prevention and safety protection functions will fail. When a fire occurs, the fire will spread rapidly, posing a serious threat to the lives, assets and information security of people in the venue.

[0006] In these special scenarios, fire doors and windows such as glass need to be replaced as soon as possible when damaged; however, the existing technology has obvious deficiencies when dealing with the maintenance of fire doors and windows in special places; the present invention focuses on these problems and strives to develop while ensuring that the sealing of doors and windows meets the standards, while achieving rapid disassembly and installation, thereby improving the maintenance efficiency of fire doors and windows in special places and ensuring the stable operation of special places. Summary of the invention

DETAILED DESCRIPTION

[0040] The following combination Figures 1 to 20 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a heat-insulating and heat-preserving fireproof door and window sealing structure. The present application mainly realizes indoor heat preservation and fire prevention through the door and window sealing structure. It can improve the heat-preserving and fire-preventing capabilities of the glass by arranging double-layer fireproof glass and sealing the double-layer glass through a sealing structure, and then injecting inert gas between the glasses. In particular, when the glass needs to be replaced, the glass can be directly driven to rotate on the door frame so that the end face of one side of the glass directly corresponds to the operator. The operator can move the glass out of the installation groove without forcibly disassembling it, and then replace it with a new glass. In the process of replacing the glass, the door will automatically lock on the door frame and cannot be pushed, so as to prevent the operator from forgetting to lock the door and accidentally opening the door when replacing the glass, thereby causing safety hazards.

[0042] Example 1: Reference Figure 1 , Figure 2 and Figure 3 As shown, it includes a main frame 1, a door 10, a rotating shaft 11, a rotating unit 2 and a glass 12. The door 10 is hinged inside the main frame 1, and a closer (not shown, known technology) is provided at the hinge of the door 10 and the main frame 1. The door 10 can be opened in the main frame 1. When the door 10 is no longer subjected to force, the closer drives the door 10 to close. A rectangular groove is provided on the door 10, and the upper and lower inner walls of the rectangular groove are both rotatably inserted with a rotating shaft 11. A rotating unit 2 is provided between the rotating shafts 11, that is, the rotating unit 2 can be rotated in the rectangular groove through the rotating shaft 11, and the glass 12 is installed on the rotating unit 2 and is used to drive the glass 12 to rotate, and the glass 12 is made of fire-resistant material and has the characteristics of resisting flame baking without breaking in a fire. In addition, the main frame 1 and the door 10 are both made of fire-resistant materials, such as aluminum alloy, to enhance the fire resistance of the overall structure.

[0043] Reference Figure 4 , Figure 5 and Figure 6 As shown, the rotating unit 2 is used to drive the glass 12 to rotate; specifically, the rotating unit 2 includes a rectangular frame plate 20, a rectangular block 21, an insertion groove 22 and a blocking block 23, two symmetrically distributed rectangular frame plates 20 are located in the rectangular groove, and rectangular blocks 21 are symmetrically arranged at the four corners and the middle between the two rectangular frame plates 20, and the rectangular block 21 in the middle is connected to the corresponding rotating shaft 11, that is, the two rectangular frame plates 20 are connected to each other through the rectangular blocks 21, and the rotating shaft 11 can also limit the rectangular frame plates 20 through the corresponding rectangular blocks 21, so that the rectangular frame plates 20 can move in the rectangular groove through the rotating shaft 11.

[0044] Insertion grooves 22 are symmetrically provided between the three corresponding rectangular blocks 21, and the glass 12 is inserted between the upper and lower corresponding insertion grooves 22. A blocking block 23 with an L-shaped cross-section is also provided on the inner wall of the rectangular frame plate 20. One side of the blocking block 23 is in contact with the surface of the glass 12. The glass 12 can be inserted between the rectangular blocks 21 through the upper and lower corresponding insertion grooves 22. There are two groups of upper and lower corresponding insertion grooves 22 in total, that is, two pieces of glass 12 can be inserted, further increasing the fire resistance. The blocking block 23 is used to block the gap between the glass 12 and the rectangular frame plate 20 to prevent foreign matter from entering the two glasses 12 from the corners of the rectangular frame plate 20 and the sides of the glass 12.

[0045] When installing the glass 12, first use external force to drive the rectangular frame plate 20 to flip ninety degrees in the rectangular groove through the limit of the rotating shaft 11, so that the insertion groove 22 corresponds to the installer, and then insert the glass 12 into the insertion groove 22 on the rectangular block 21 on one side to complete the installation of the glass 12. After the two pieces of glass 12 are installed, use external force again to drive the rectangular frame plate 20 to rotate to the initial position.

[0046] It should be noted that the insertion grooves 22 on the two upper and lower corresponding rectangular blocks 21 on one side pass through the outer walls on both sides thereof, while the two rectangular blocks 21 on the other side are provided with the insertion grooves 22 on one side and are blocked on the other side. In this way, after the glass 12 enters the interior of the rectangular block 21 from the insertion grooves 22 on one side, its side surface will contact the inner wall of the insertion grooves 22 on the rectangular block 21 on the other side, thereby preventing the glass 12 from being inserted too deeply and extending too much from the slot on the other side or falling off, causing damage to the glass 12.

[0047] Continue to refer to Figure 3 , Figure 7 and Figure 8 As shown, the door 10 is provided with sliding grooves 30 extending through its outer wall and the rectangular groove on all sides, and an inner sealing component 3 for sealing the gap between the glasses 12 is arranged in the sliding groove 30; specifically, the inner sealing component 3 includes a sliding groove 30, a strip plate 31, a sealing strip 32, a circular groove 33 and an avoidance groove 34, the strip plate 31 is slidably arranged inside the sliding groove 30, and a sealing strip 32 with an "E"-shaped cross-section is arranged on the side of the strip plate 31 facing the glass 12, that is, when the strip plate 31 is driven by an external force, the corresponding sealing strip 32 can be driven to move toward the direction of the two glasses 12, and finally the three extension sections of the sealing strip 32 will contact the opposite sides and opposite sides of the two glasses 12, and seal the gap between the two glasses 12, and because the sealing strip 32 is made of a flexible material, it can also play a certain buffering role after the glass 12 is impacted.

[0048] A circular groove 33 is formed on the upper and lower corresponding strip plates 31, and the rotating shaft 11 is located in the circular groove 33. An avoidance groove 34 is formed in the middle of the upper and lower sealing strips 32, and the corresponding sealing strips 32 are divided into two sections by the avoidance groove 34. Figure 3 As shown, the upper and lower ends of the main frame 1 both have a strip section extending into the corresponding sliding groove 30, and the rotating shaft 11 is rotatably inserted on the strip section, and the upper rotating shaft 11 is located in the circular groove 33. The circular groove 33 is used to avoid the rotating shaft 11 when the strip plate 31 moves, so as to prevent the strip plate 31 from colliding with the rotating shaft 11.

[0049] Since there is a rectangular block 21, a rotating shaft 11 and an extension section of the main frame 1 in the sliding groove 30 in the middle of the rectangular frame plate 20, the avoidance groove 34 is used to avoid them, so that after the sealing strip 32 is inserted between the glasses 12, its outer side can contact the corresponding rectangular block 21, and cooperate with the rectangular block 21 to seal the gap between the glasses 12, and the two extension sections before and after the sealing strip 32 cover the outer side of the glass 12, and then the corresponding blocking block 23 blocks the outer side of the glass 12, so as to further improve the sealing effect of the glass 12.

[0050] If the glass 12 needs to be replaced, the strip plate 31 is moved to the initial position by external force so that the sealing strip 32 is no longer inserted between the glasses 12. That is, the rectangular frame plate 20 is no longer limited by the sealing strip 32. The glass 12 can be taken out from the corresponding insertion groove 22 by rotating the rectangular frame plate 20.

[0051] Reference Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, an external sealing component 4 for sealing the gap between the door 10 and the main frame 1 is also provided in the sliding groove 30; specifically, the external sealing component 4 includes a clamping groove 40, a sliding plate 41, a clamping block 42 and a pushing rod 43. The clamping groove 40 is provided on the inner wall of the main frame 1, and there is no clamping groove 40 at the hinge between the main frame 1 and the door 10. The clamping groove 40 corresponds to the sliding groove 30, and a sliding plate 41 is provided in the sliding groove 30.

[0052] That is, the sliding plate 41 can reciprocate in the corresponding sliding groove 30 .

[0053] A clamping block 42 located in the corresponding clamping groove 40 is provided on one side of the sliding plate 41, and a sealing strip (not shown in the figure) is provided on the outer side of the clamping block 42, and a pushing rod 43 is provided between the sliding plate 41 and the inner wall of the corresponding sliding groove 30. In the initial state, the pushing rod 43 drives the clamping block 42 to press against the corresponding clamping groove 40 through the sliding plate 41, and seals the gap between the main frame 1 and the door 10 through the sealing strip, thereby improving the thermal insulation performance and preventing the leakage of cold air or hot air. In addition, the design of the pushing rod 43 and the sliding plate 41 also takes into account the wear problem caused by long-term use, and adopts high-strength materials and precise manufacturing processes to ensure that it can maintain a good working condition under frequent use. At the same time, the sealing strip adopts special materials that are resistant to high temperature, low temperature and aging, which further extends the service life.

[0054] When a person pushes the door 10, the pushing force will drive the clamping block 42 to move out of the corresponding clamping groove 40, so that the door 10 is no longer limited by the clamping block 42 and opens. Similarly, when the door 10 is closed, the clamping block 42 can also move back into the clamping groove 40 under the indirect push of the corresponding pushing rod 43, and continue to limit the door 10 in the main frame 1.

[0055] Reference Fig.13 and Fig.14 As shown, any one of the rectangular blocks 21 is provided with a gas replenishing component 5 for filling inert gas toward the space between the glasses 12; specifically, the gas replenishing component 5 includes a bending groove 50 and a one-way valve 51, the bending groove 50 is opened inside the rectangular block 21, and the two sides of the bending groove 50 respectively penetrate to the space between the glasses 12 and the outer wall of the rectangular block 21, the bending groove 50 is located on one side of the outer wall of the rectangular block 21 and a one-way valve 51 is inserted, and the opening direction of the one-way valve 51 is from outside to inside. When the glass 12 is installed and the inner sealing component 3 seals the side of the glass 12, it is connected to the air inlet of the one-way valve 51 through an external gas replenishing device (known technology, no further description), and inert gas, such as argon or krypton, is supplied toward the bending groove 50 through the one-way valve 51. The purpose of this step is to further enhance the thermal insulation, heat insulation and sound insulation performance of the glass 12.

[0056] Specifically, after the inert gas enters the bending groove 50 through the one-way valve 51, it will enter between the glasses 12, and the air pressure will drive the glasses 12 to move toward the front and rear sides, so that the glass 12 is in close contact with the sealing strip 32, thereby improving the air tightness. Since the opening direction of the one-way valve 51 is from outside to inside, it ensures that the gas can only enter but not easily flow out. The inert gas has low thermal conductivity and good sound insulation performance, which can effectively reduce heat transfer and sound transmission.

[0057] The rectangular block 21 is also provided with an air pressure sensor located between the glasses 12. The air pressure sensor will monitor in real time whether the air pressure between the glasses 12 is sufficient. If the inert gas leaks during use, a display screen is provided on the air pressure sensor to remind personnel to replenish the gas in time. The operator can also view the air pressure intensity at this time more intuitively through the glass 12 through the display screen and adjust the amount of gas replenishment.

[0058] Example 2: Reference Fig.15 , Fig.16 , Fig.17 , Fig.18 and Fig.19 As shown, on the basis of the first embodiment, in order to drive the rotating frame to flip, a driving unit 6 is provided on the sliding groove 30; specifically, the driving unit 6 includes a driving rack 60, a transmission shaft 61, a transmission gear 62, a rotating cylinder 63, a transmission cylinder 64, a worm wheel 65, a worm 66, a structural groove 67, an extension shaft 68, a transmission belt 69, a driving groove 610, a screw 611, a driving key 612 and a hexagonal groove 613. The driving rack 60 is arranged on one side of the strip plate 31, and a transmission shaft 61 is provided on the inner wall of the sliding groove 30 through a torsion spring rotation. A transmission gear 62 meshing with the corresponding driving rack 60 is provided on the outer side of the transmission shaft 61. In the initial state, the corresponding torsion spring drives the transmission gear 62 through the transmission shaft 61 to drive the driving rack 60 and the strip plate 31 to move toward the direction of the glass 12, so that the sealing strip 32 is inserted between the glasses 12 to seal them.

[0059] A rotating cylinder 63 and a transmission cylinder 64 are rotatably arranged on the upper and lower inner walls of the sliding groove 30 on one side. A worm wheel 65 is sleeved on the outer side of the rotating shaft 11, and a worm 66 meshing with the worm wheel 65 is sleeved on the outer side of the rotating cylinder 63. When the rotating cylinder 63 is driven by an external force, the worm 66 will be driven to rotate, so that the worm 66 can drive the rotating shaft 11 to rotate through the worm wheel 65, and then drive the rotating unit 2 to rotate.

[0060] The four corners of the door 10 are also provided with structural grooves 67, and an extension shaft 68 is rotatably arranged in the structural groove 67. A transmission belt 69 is sleeved between the transmission cylinder 64, the transmission shaft 61 and the extension shaft 68. When the transmission cylinder 64 is driven by an external force, it can drive several transmission shafts 61 to rotate through the transmission belt 69 and the extension shaft 68, so that the transmission shaft 61 can indirectly drive the strip plate 31 to move in a direction away from the glass 12, so that the glass 12 is no longer sealed, and the rectangular frame plate 20 will not be limited by the sealing strip 32. At this time, the corresponding rotating shaft 11 is driven to rotate, which can drive the rotating unit 2 to rotate, and the glass 12 can be disassembled or installed.

[0061] After installation, the rectangular frame plate 20 is first rotated to the initial position, and then the driving cylinder 64 is driven to rotate in the opposite direction, so that the corresponding torsion spring can indirectly drive the sealing strip 32 to be inserted between the glasses 12 and limit the rectangular frame plate 20 to prevent it from rotating.

[0062] A driving groove 610 is also provided on the inner wall of the rotating cylinder 63 and the transmission cylinder 64, and a screw rod 611 is also provided on one side of the door 10 by threading, and one side of the screw rod 611 is inserted into the rotating cylinder 63 and the transmission cylinder 64, and a driving key 612 located in the corresponding driving groove 610 is provided on the outer side of the screw rod 611, and a hexagonal groove 613 is provided on the side of the screw rod 611 facing the outside of the door 10, that is, the hexagonal rod is inserted into the hexagonal groove 613 to drive the screw rod 611 to rotate , and the screw 611 will move downward during the rotation process, so that the driving key 612 on its outside can first drive the transmission cylinder 64 to rotate through the driving groove 610, so that the sealing strip 32 moves and is no longer inserted between the glasses 12, and then the driving key 612 will move into the driving key 612 on the inside of the rotating cylinder 63. At this time, the screw 611 can synchronously drive the transmission cylinder 64 and the rotating cylinder 63 to rotate through the driving key 612, so that the rectangular frame plate 20 rotates.

[0063] Although the sealing strip 32 is no longer inserted between the rectangular frame plates 20, it will continue to move until the rectangular frame plates 20 are rotated ninety degrees. The hexagonal rod is kept stationary, the glass 12 is replaced, and then the screw 611 is driven in the reverse direction by the hexagonal rod to rotate, so that the rectangular frame plates 20 are rotated to the initial position. When the rectangular frame plates 20 move to the initial position, the driving key 612 only drives the screw 611 to rotate, so that the sealing strip 32 can be inserted into the rectangular frame plates 20 to limit them.

[0064] After the sealing strip 32 moves out of the glass 12, the end of the driving rack 60 will correspond to the inner side of the sliding plate 41. That is, when the external force is applied again, the sliding plate 41 will contact the end of the driving rack 60 and cannot move, so that the clamping block 42 cannot move out of the clamping groove 40, so that the door 10 is always limited on the main frame 1, preventing the door 10 from being accidentally opened when the operator replaces the glass 12.

[0065] Example 3: Reference Fig. 20As shown, on the basis of the second embodiment, in order to fix the door 10 in the main frame 1 in daily use so that it cannot be opened, a locking assembly 7 is provided on the door 10; specifically, the locking assembly 7 includes a fixing rod 70 and a handle 71, a threaded groove is opened on one side of the door 10 and passes through the corresponding sliding groove 30, and a fixing rod 70 is threadedly inserted in the threaded groove, one side of the fixing rod 70 corresponds to the inner side of the corresponding sliding plate 41, and a handle 71 is provided on the side of the fixing rod 70 located outside the door 10.

[0066] The handle 71 can be used to drive the fixing rod 70 to move in the direction of the sliding groove 30, so that the fixing rod 70 corresponds to the inner side of the sliding plate 41. When the door 10 is driven by an external force, the sliding plate 41 is blocked by the fixing rod 70, so that the door 10 cannot be opened. The fixing rod 70 is made of plastic, that is, in the event of a fire, if the door 10 is limited by the fixing rod 70 at this time, the fixing rod 70 will melt in a high temperature environment and will no longer limit the door 10, so that the door 10 can be opened directly. In an emergency, a person can directly kick the door 10 to break the fixing rod 70 and open the door 10, thereby saving the time of releasing the limit of the door 10 through the handle 71.

[0067] During operation: In the first step, the door 10 is in a closed state, and the clamping block 42 of the external sealing assembly 4 is pressed against the clamping groove 40 of the inner wall of the main frame 1 by the action of the push rod 43, and the gap between the main frame 1 and the door 10 is sealed by the sealing strip 32 to prevent cold air or hot air from leaking out, while improving the thermal insulation performance.

[0068] In the second step, the strip plate 31 of the inner sealing component 3 drives the sealing strip 32 to contact the glass 12 under the action of the torsion spring and the transmission gear 62, so as to seal the gap between the glasses 12, and the sealing strip 32 can play a buffering role when the glass 12 is impacted.

[0069] In the third step, the air supply component 5 fills inert gas (such as argon or krypton) between the glasses 12 through the one-way valve 51 via the external air supply equipment to enhance the thermal insulation, heat insulation and sound insulation performance of the glasses 12. The air pressure sensor monitors the air pressure between the glasses 12 in real time and reminds the personnel to replenish it when it is insufficient.

[0070] In the fourth step, when the door 10 needs to be opened, the person pushes the door 10, and the pushing force drives the clamping block 42 to move out of the clamping groove 40, and the door 10 is no longer restricted and can be opened; after the door 10 is closed, the clamping block 42 returns to the clamping groove 40 under the action of the pushing rod 43, and continues to limit the door 10 in the main frame 1.

[0071] The fifth step is to replace the glass 12 by rotating the screw 611 through the hexagonal rod, and the driving key 612 first drives the transmission cylinder 64 to rotate, so that the strip plate 31 moves, and the sealing strip 32 is no longer inserted between the glasses 12. At this time, when the door 10 is subjected to external force, the sliding plate 41 contacts the end of the driving rack 60 and cannot move, and the clamping block 42 cannot be moved out of the clamping groove 40, and the door 10 is limited; then the driving key 612 drives the rotating cylinder 63 to rotate, so that the rotating shaft 11 rotates, and drives the rotating unit 2 to rotate, and the glass 12 can be taken out from the insertion groove 22.

[0072] Step 6. When installing the glass 12, first insert the glass 12 into the insertion groove 22 of the rectangular block 21, then reversely rotate the screw 611 through the hexagonal rod to rotate the rectangular frame plate 20 to the initial position, and reinsert the sealing strip 32 between the glasses 12 and limit the rectangular frame plate 20 to prevent it from rotating.

[0073] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
