Description

Technical Field

[0001] The present invention belongs to the technical field of doors and windows, and particularly relates to a new type of environmentally friendly and energy-saving door and window. Background Art

[0002] Doors and windows are one of the important components of building shapes. According to their different positions, doors and windows can be divided into enclosing components and partitioning components. With the development of economy and technology, people have higher and higher requirements for doors and windows, resulting in more and more functions of doors and windows. According to different design requirements, doors and windows can be divided into heat-insulating doors and windows, heat-insulating doors and windows, sound-insulating doors and windows, light-adjusting doors and windows, waterproof doors and windows, fireproof doors and windows, and ventilation doors and windows, etc. Among them, heat-insulating doors and windows and heat-insulating doors and windows belong to environmentally friendly and energy-saving doors and windows, which can prevent indoor heat or cold air from overflowing through the doors and windows, so as to achieve the purpose of energy conservation and environmental protection.

[0003] Existing new type of environmentally friendly and energy-saving doors and windows include an outer frame and an inner frame. The inner frame is rotatably installed in the outer frame, and energy-saving glass is arranged in the inner frame. Sound-absorbing cotton and sealing strips are respectively installed at the contact positions between the inner frame and the outer frame. During the process of the inner frame being retracted into the outer frame, the sealing strip on the inner frame will be mutually extruded with the sealing strip on the outer frame. Through the mutual extrusion method, the sealing strip can seal the gap between the outer frame and the inner frame, thereby realizing the heat-insulating function of the door and window.

[0004] However, the force generated by the mutual extrusion will cause the sealing strip to easily fall off from the outer frame or the inner frame. When the sealing strip in the falling-off state is mutually extruded, it not only cannot fully seal the gap between the outer frame and the inner frame, but also the force generated by the mutual extrusion will cause the sealing strip to be damaged and other phenomena. If it is not replaced or repaired in time, it will reduce the heat-insulating effect of the door and window, thus unable to meet the daily needs of users.

[0005] Therefore, in view of the above current situation, there is an urgent need to develop a new type of environmentally friendly and energy-saving door and window to overcome the deficiencies in current practical applications. Summary of the Invention

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the embodiment of the present invention is to provide a new type of environmentally friendly and energy-saving door and window to solve the problems in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0012] The other end of the sealing mechanism is connected to a limiting mechanism. One end of the limiting mechanism is fixed on one side of the fan frame close to the window frame. The other end of the limiting mechanism is respectively installed in the installation cavity and the installation groove;

[0013] When the fan frame is in the open state, the limiting mechanism controls the sealing piece to contract on the window frame by cooperating with the sealing mechanism; during the process of the fan frame rotating back to the window frame, the fan frame drives the sliding piece to slide through the first connecting piece, the sliding piece drives the rolling piece to move downward through the moving piece, the rolling piece drives the rotating piece to rotate by moving downward, the rotating piece drives the rack to move through the gear, the rack drives the first piston assembly to move through the second connecting piece, and the first piston assembly drives the second piston assembly to move by cooperating with the air storage tank and the inert gas;

The limiting mechanism releases the limit on the sealing mechanism by working. The second piston assembly drives the sealing mechanism to work through the inert gas.

[0019] As a further technical solution of the present invention, the limiting mechanism includes a control member, a deflecting member, a rotating shaft, a mounting seat, a protrusion, a limiting member, a fourth elastic member, a driving member, and a connecting seat. The control member is fixed on one side of the fan frame close to the window frame. The control member intermittently abuts against the deflecting member. The deflecting member is rotatably installed in the installation cavity through the rotating shaft. One end of the rotating shaft is connected to a third elastic member provided in the installation cavity. The other end of the rotating shaft is provided with a mounting seat. A protrusion that abuts against one end of the limiting member is fixed on the mounting seat. There are two groups of the limiting members. The two groups of the limiting members are staggered with each other and rotatably installed in the installation cavity. One ends of the two groups of the limiting members are movably connected through the fourth elastic member. The other ends of the two groups of the limiting members are intermittently matched with a card slot formed on the driving member. The driving member is slidably installed in the installation cavity.

[0021] As a further technical solution of the present invention, the driving member is a columnar structure, and the other end of the driving member extends outside the inspection panel and is equipped with a handle.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When the sash frame is in the open state or the ready-to-open state, the limiting mechanism limits and fixes the piston rod, so that the third piston in the delivery cylinder is at the end away from the sealing member. The third piston cooperates with the delivery cylinder to suck the inert gas in the sealing member into the delivery cylinder, so that the sealing member shrinks on the window frame. When the sash frame is opened or closed, the sealing member is not squeezed, thereby increasing the service life of the sealing member and further improving the practicality of the door and window.

[0024] During the process of the sash frame rotating back to the window frame, the sash frame drives the sliding member to slide via the first connecting member, the sliding member drives the rolling member to move downward via the moving member, the rolling member drives the rotating member to rotate by moving downward, the rotating member drives the rack to move via the gear, the rack drives the first piston to move via the second connecting member, the first piston can drive the second piston to move by cooperating with the gas storage tank and the inert gas, and the second piston squeezes the second elastic member;

[0025] When the sash frame rotates back into the window frame, the sash frame drives the limiting mechanism through the mounting groove, so that the limiting mechanism releases the limit on the piston rod. At this time, the second piston cooperates with the second elastic member to transport the inert gas from the connecting pipe to the connecting cylinder, so that the gas pressure in the connecting cylinder increases. The force generated by the gas pressure drives the third piston in the connecting cylinder to move. The third piston in the connecting cylinder drives the third piston in the delivery cylinder to move through the piston rod. The third piston in the delivery cylinder transports the inert gas to the sealing member by moving, so that the sealing member expands in the closed groove, thereby quickly sealing the gap between the window frame and the sash frame. Due to the characteristics of the inert gas, the thermal insulation performance of the doors and windows can be further improved, thereby achieving the purpose of energy saving and environmental protection of the doors and windows, and thus improving the practicality of the doors and windows.

The two ends of the air storage tank 51 are respectively installed with the first piston assembly 52 and the second piston assembly 53. The first piston assembly 52 is connected to the second connecting member 48. The air storage tank 51 is also connected to a sealing mechanism 7 distributed in the installation cavity 11. One end of the sealing mechanism 7 is communicated with a sealing member 76 installed on the window frame 1. The sealing member 76 cooperates with the sealing groove 21. The air storage tank 51 and the sealing mechanism 7 are both filled with inert gas;

[0045] The other end of the sealing mechanism 7 is connected to the limiting mechanism 6. One end of the limiting mechanism 6 is fixed to one side of the fan frame 2 close to the window frame 1, and the other end of the limiting mechanism 6 is respectively installed in the installation cavity 11 and the installation groove 12.

[0046] As Figure 8 shown, as a preferred embodiment of the present invention, the first piston assembly 52 includes a first piston 521, a first guide rod 522, and a first elastic member 523. The first piston 521 is slidably installed at one end of the gas storage tank 51 close to the control mechanism 4. One end of the first piston 521 is connected to the second connecting member 48, and a first guide rod 522 is fixed to the other end of the first piston 521. One end of the first guide rod 522 is slidably connected to the inner wall of the gas storage tank 51. A first elastic member 523 is installed on the first guide rod 522, and both ends of the first elastic member 523 are connected to the first piston 521 and the inner wall of the gas storage tank 51 respectively.

[0047] As Figure 9 shown, as a preferred embodiment of the present invention, the second piston assembly 53 includes a second piston 531, a second guide rod 532, and a second elastic member 533. The second piston 531 is slidably installed at the other end of the gas storage tank 51. The middle part of the second piston 531 is slidably matched with the second guide rod 532 fixed in the gas storage tank 51. A second elastic member 533 is installed on the second guide rod 532, and both ends of the second elastic member 533 are connected to the second piston 531 and the inner wall of the gas storage tank 51 respectively.

[0048] As Figure 8 and Figure 9 shown, as a preferred embodiment of the present invention, the outer walls of the first piston 521 and the second piston 531 are both in contact with the inner wall of the gas storage tank 51, and the gas storage tank 51 between the first piston 521 and the second piston 531 is communicated with the sealing mechanism 7 distributed in the installation cavity 11.

[0049] As Figure 4 and Figure 7 shown, as a preferred embodiment of the present invention, the sealing mechanism 7 includes a piston rod 71, a third piston 72, a delivery cylinder 73, a connection cylinder 74, and a connection pipe 75. The piston rod 71 is slidably installed in the installation cavity 11, and the piston rod 71 is connected to the limiting mechanism 6. Both ends of the piston rod 71 are provided with third pistons 72. One group of the third pistons 72 is slidably installed in the delivery cylinder 73. One end of the delivery cylinder 73 is communicated with the sealing member 76, and an inert gas is provided in the delivery cylinder 73. The other group of the third pistons 72 is slidably installed in the connection cylinder 74. One end of the connection cylinder 74 is communicated with the gas storage tank 51 through the connection pipe 75.

[0050] In this embodiment, when the fan frame 2 is in the open state or the to-be-opened state, the limiting mechanism 6 limits and fixes the piston rod 71 at this time, so that the third piston 72 in the conveying cylinder 73 is at the end far from the sealing member 76. The third piston 72 can suck the inert gas in the sealing member 76 into the conveying cylinder 73 by cooperating with the conveying cylinder 73, so that the sealing member 76 shrinks on the window frame 1. When the fan frame 2 is opened or closed, it will not squeeze the sealing member 76, thereby increasing the service life of the sealing member 76 and further improving the practicability of the doors and windows;

[0051] During the process of the fan frame 2 rotating back to the window frame 1, the fan frame 2 drives the sliding member 42 to slide through the first connecting member 41. The sliding member 42 drives the rolling member 44 to move downward through the moving member 43. The rolling member 44 drives the rotating member 45 to rotate by moving downward. The rotating member 45 drives the rack 47 to move through the gear 46. The rack 47 drives the first piston 521 to move through the second connecting member 48. The first piston 521 can drive the second piston 531 to move by cooperating with the gas storage tank 51 and the inert gas. The second piston 531 squeezes the second elastic member 533;

[0052] When the fan frame 2 rotates back into the window frame 1, the fan frame 2 drives the limiting mechanism 6 to work through the installation groove 12, so that the limiting mechanism 6 releases the limit on the piston rod 71. At this time, the second piston 531 transports the inert gas to the connecting cylinder 74 through the connecting pipe 75 by cooperating with the second elastic member 533, so that the gas pressure in the connecting cylinder 74 increases. The force generated by the gas pressure drives the third piston 72 in the connecting cylinder 74 to move. The third piston 72 in the connecting cylinder 74 drives the third piston 72 in the conveying cylinder 73 to move through the piston rod 71. The third piston 72 in the conveying cylinder 73 transports the inert gas into the sealing member 76 by moving, so that the sealing member 76 expands in the sealing groove 21, thereby quickly sealing the gap between the window frame 1 and the fan frame 2. And due to the characteristics of the inert gas, the heat preservation performance of the doors and windows can be further improved, so as to achieve the purpose of energy conservation and environmental protection of the doors and windows, and further improve the practicability of the doors and windows.

[0053] In a preferred embodiment, the sealing groove 21 is arranged on the fan frame 2 around the middle glass and connected end to end. When the sealing member 76 expands, its outer wall will fit on the inner wall of the sealing groove 21, so as to seal the gap between the fan frame 2 and the window frame 1;

[0054] The first connecting member 41, the second connecting member 48 and the rotating member 45 preferably adopt a rod-shaped structure;

[0055] The sliding member 42 and the moving member 43 preferably adopt a block-shaped structure;

[0056] The rolling member 44 preferably adopts a roller.

[0057] Both the first elastic member 523 and the second elastic member 533 preferably adopt a spring. The first elastic member 523 is for keeping the rolling member 44 in contact with the side wall of the moving member 43 all the time, while the second elastic member 533 is for cooperating with the second piston 531 to squeeze the gas in the air storage tank 51 into the connecting cylinder 74.

[0058] The sealing member 76 preferably adopts a tubular structure with an oval cross-section.

[0059] Such as Figure 6 and Figure 10 As shown, as a preferred embodiment of the present invention, the limiting mechanism 6 includes a control member 61, a deflecting member 62, a rotating shaft 63, a mounting seat 64, a protrusion 65, a limiting member 66, a fourth elastic member 67, a driving member 68 and a connecting seat 69. The control member 61 is fixed on one side of the fan frame 2 close to the window frame 1. The control member 61 intermittently contacts the deflecting member 62. The deflecting member 62 is rotatably mounted in the mounting cavity 11 through the rotating shaft 63. One end of the rotating shaft 63 is connected to a third elastic member arranged in the mounting cavity 11. The other end of the rotating shaft 63 is provided with a mounting seat 64. A protrusion 65 that contacts one end of the limiting member 66 is fixed on the mounting seat 64. There are two groups of the limiting members 66. The two groups of the limiting members 66 are staggered with each other and rotatably mounted in the mounting cavity 11. One ends of the two groups of the limiting members 66 are movably connected through the fourth elastic member 67. The other ends of the two groups of the limiting members 66 are intermittently engaged with a clamping groove 681 formed on the driving member 68. The driving member 68 is slidably mounted in the mounting cavity 11. One end of the driving member 68 is fixedly connected to a piston rod 71 distributed in the mounting cavity 11 through the connecting seat 69.

[0060] Such as Figure 6 As shown, as a preferred embodiment of the present invention, the control member 61 is a special-shaped block structure. Both sides of the position on the control member 61 that contacts the deflecting member 62 are arc surfaces, and neither side of the arc surfaces on the control member 61 contacts the deflecting member 62.

[0061] Such as Figure 5 and Figure 10 As shown, as a preferred embodiment of the present invention, the driving member 68 is a columnar structure, and the other end of the driving member 68 extends outside the maintenance plate 3 and is provided with a pull handle 8.

[0062] In this embodiment, when the fan frame 2 is in the open state or the to-be-opened state, at this time, the limiting member 66 can cooperate with the convex 65 and the fourth elastic member 67 to cooperate with the card slot 681, thereby realizing the limitation and fixation of the driving member 68. The driving member 68 limits and fixes the piston rod 71, so that the third piston 72 in the conveying cylinder 73 is at the end far from the sealing member 76. The third piston 72 can suck the inert gas in the sealing member 76 into the conveying cylinder 73 by cooperating with the conveying cylinder 73, so that the sealing member 76 contracts on the window frame 1. When the fan frame 2 is opened or closed, it will not squeeze the sealing member 76, thereby increasing the service life of the sealing member 76 and further improving the practicability of the doors and windows;

[0063] When the fan frame 2 rotates back into the window frame 1, the fan frame 2 drives the control member 61 to rotate into the installation groove 12 and abuts against the deflecting member 62. The control member 61 drives the rotating shaft 63 to rotate through the deflecting member 62. The rotating shaft 63 drives the convex 65 to rotate through the mounting seat 64. The convex 65 is separated from the limiting member 66 by rotation. The fourth elastic member 67 drives the two limiting members 66 to cross-rotate through its own elastic force. The two limiting members 66 are cross-rotated, thereby releasing the limitation and fixation of the driving member 68, and further releasing the limitation of the piston rod 71, so that the sealing member 76 can expand in the sealing groove 21;

[0064] When the rotating shaft 63 rotates, it will also squeeze the third elastic member, so that the third elastic member is in a state of storing energy. When the fan frame 2 completely rotates back into the window frame 1, at this time, the control member 61 is separated from the deflecting member 62, and the third elastic member drives the rotating shaft 63 to rotate back through its own elastic force. The rotating shaft 63 drives the convex 65 to rotate back through the mounting seat 64; when the fan frame 2 rotates outward, the control member 61 drives the rotating shaft 63 to rotate in the reverse direction through the deflecting member 62. The rotating shaft 63 drives the convex 65 to rotate in the reverse direction through the mounting seat 64. The length of the convex 65 in the reverse rotation direction is greater than the length of the convex 65 in the forward rotation direction, so that when the convex 65 rotates in the reverse direction, it always abuts against the limiting member 66, making the limiting member 66 in a static state;

[0065] When the fan frame 2 is in the window frame 1 and the fan frame 2 needs to be opened, in order to prevent the fan frame 2 from damaging the sealing member 76 when it is opened, the user can drive the driving member 68 to move back through the handle 8. The driving member 68 drives the card slot 681 to move back, so that the card slot 681 moves back to the position where it cooperates with the limiting member 66. At this time, the fourth elastic member 67 drives the limiting member 66 to cooperate with the card slot 681 again through its own elastic force, thereby realizing the re-limitation and fixation of the driving member 68. When the driving member 68 moves back, it will drive the piston rod 71 to move back through the connecting seat 69, so that the inert gas in the sealing member 76 returns to the conveying cylinder 73 again, and then the sealing member 76 contracts on the window frame 1 again and is separated from the fan frame 2.

[0066] In a preferred embodiment, the deflecting member 62 preferably adopts a block-shaped structure;

[0067] The limiting member 66 preferably adopts a Z-shaped rod structure;

[0068] The third elastic member is preferably a spiral elastic sheet;

[0069] The fourth elastic member 67 is preferably an arc spring;

[0070] The driving member 68 preferably adopts a circular columnar structure.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
