Description

Technical Field

[0001] The embodiment of the present invention relates to the technical field of curtain wall ventilation, and in particular to a transmission device for opening and closing a ventilation panel of a unit curtain wall. Background Art

[0002] Curtain wall is the exterior wall maintenance of the building. It is non-load-bearing and is hung up like a curtain. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and supporting structure systems. It can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an external building enclosure structure or decorative structure that does not bear the effect of the main structure. Double-layer curtain wall or ventilated curtain wall is a more popular building external enclosure structure. In terms of ventilation method, it can be divided into two major systems: internal ventilation and external ventilation. The outer layer of the internal ventilation double-layer curtain wall is a closed structure. Ventilation is carried out in the space on both sides of the curtain wall. Usually, it requires the cooperation of a centralized forced ventilation system to exchange with nature and achieve the final effect. External ventilation uses the air outside the building to reasonably organize the airflow through the air inlet and outlet of the double-layer curtain wall to directly exchange with nature and achieve the final effect.

[0003] The vents of the open type external ventilation curtain wall can be opened and closed. The inner curtain wall of the open type external ventilation curtain wall is closed and uses hollow glass. The outer curtain wall uses single-layer glass and is equipped with air inlets and exhaust vents. The more popular vent design structure on the market is the electromagnetic design structure. This design is difficult to open without power, and it is easy to form electromagnetic shielding and cause functional failure, which is unstable. Therefore, a simple vent design that can meet the requirements of vent opening and closing and can operate stably to achieve the effect of continuous ventilation is an urgent problem to be solved.

[0021] In a feasible solution, the reset mechanism of the transmission device for opening and closing the unit curtain wall ventilation panel includes: a bottom frame, a spring and a rectangular ring;

[0022] The baffle plate is provided with a groove, and the rectangular ring is clamped in the groove;

[0023] One end of the spring is fixed to the bottom frame, and the other end of the spring is fixed to the rectangular ring. The spring is used to separate the baffle plate from the ventilation plate.

[0024] In a feasible solution, the transmission device for opening and closing the unit curtain wall ventilation panel also includes: a sliding rod;

[0025] The bottom frame is provided with a slide groove, the slide rod is located in the slide groove, and the slide rod can roll in the slide groove;

[0026] One end of the spring is sleeved on the rectangular ring, and the other end of the spring is fixed on the sliding rod.

[0028] The rubber sealing pad is fixed on the baffle plate, and the rubber sealing pad is located between the baffle plate and the ventilation plate.

[0029] In a feasible solution, the shift plate of the transmission device for opening and closing the ventilation panel of the unit curtain wall also includes a rubber head, and the rubber head is located at the end that abuts against the baffle.

[0030] In a feasible solution, the transmission device for opening and closing the ventilation panel of the unit curtain wall unit curtain wall further includes: a locking mechanism;

[0034] In a feasible solution, the cover plate, pressure plate, ventilation plate, paddle plate and baffle plate of the transmission device for opening and closing the ventilation panel of the unit curtain wall are all made of aluminum alloy.

[0035] Based on the above scheme, it can be known that the transmission device for opening and closing the ventilation plate of the unit curtain wall of the present invention includes: a rotating component, a transmission mechanism, a baffle and a unit curtain wall. The rotating component includes: a cover plate and a pressure plate, the unit curtain wall includes: a main structure and a ventilation plate, and the transmission mechanism includes: a dial plate and a pin. The ventilation plate is embedded in the main structure, and is fixed between the ventilation plate and the main structure by glass glue. A plurality of ventilation holes are provided on the ventilation plate. The pressure plate is located below the cover plate, and the pressure plate is fixed on the cover plate by threads.

In the transmission device for opening and closing the ventilation plate of the unit curtain wall of the embodiment of the present invention, the pressure plate is fixed below the cover plate, and when the cover plate and the main structure are in a gradually buckled state, the pressure plate applies a certain pressure to the dial plate, so that one end of the dial plate is pressed down, and because a pin is fixed in the middle of the dial plate, the dial plate can rotate in a plane, so the other end of the dial plate is lifted. During the process of lifting the other end of the dial plate, the other end of the dial plate abuts against the baffle plate, so that the position of the baffle plate gradually moves up and the baffle plate moves closer to the ventilation plate. Since the baffle plate is located between the dial plate and the ventilation plate, the baffle plate will fit with the ventilation plate under the action of the dial plate. Since the ventilation plate is provided with multiple ventilation holes, the ventilation holes are used for indoor and outdoor air exchange. When the baffle plate is pressed on the surface of the ventilation plate, the vents are also blocked, thereby achieving the effect of blocking air circulation. When the cover plate is gradually lifted, a gap is gradually formed between the cover plate and the main structure. As the cover plate is lifted, the position of the pressure plate gradually moves up. Since the dial plate is no longer under the pressure of the pressure plate, the dial plate naturally falls down under the influence of gravity. At the same time, the other end of the dial plate changes from abutting against the baffle plate at the beginning to a state of separation from the baffle plate. Without the abutment of the dial plate, the baffle plate is also offset to one side due to gravity and separated from the ventilation plate. At this time, the vent is opened and air exchange and circulation are circulated. This transmission device realizes indoor and outdoor air circulation through mechanical transmission. When the cover is lifted, the vent is opened and air is exchanged. When the cover is lowered, the vent is closed. It is simple to operate, easy to install, cost-saving and stable in state, ensuring the normal operation function of the vent as well as the thermal insulation and heat preservation performance.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0047] Figure 1 A three-dimensional diagram of a transmission device for opening and closing a unit curtain wall ventilation panel in an embodiment of the present invention; Figure 2 This is a schematic diagram of the unit curtain wall ventilation panel in an embodiment of the present invention in an open state; Figure 3 This is a schematic diagram of a closed state of a unit curtain wall ventilation panel in an embodiment of the present invention; Figure 4 It is a schematic diagram of the resetting mechanism of the transmission device for opening and closing the ventilation panel of the unit curtain wall in an embodiment of the present invention.

[0048] The transmission device for opening and closing the ventilation panel of the unit curtain wall in the present invention comprises: a rotating assembly 1, a transmission mechanism 2, a baffle 3 and a unit curtain wall 4. Figure 1 As shown, the rotating assembly 1 includes: a cover plate 11 and a pressure plate 12, the unit curtain wall 4 includes: a main structure 41 and a ventilation plate 42, and the transmission mechanism 2 includes: a dial plate 21 and a pin 22. The cover plate 11, the pressure plate 12, the ventilation plate 42, the dial plate 21 and the baffle 3 are all made of aluminum alloy. The aluminum alloy material has low density, high strength, good plasticity, and excellent electrical conductivity, thermal conductivity and corrosion resistance. As shown in Figure 3, the pressure plate 12 is fixed below the cover plate 11, the pressure plate 12 is perpendicular to the cover plate 11, the pressure plate 12 and the cover plate 11 are connected by threads, the dial plate 21 is located below the pressure plate 12, the pin 22 is located in the middle of the dial plate 21, and the dial plate 21 can rotate around the pin 22. The ventilation plate 42 is embedded in the main structure 41, and the ventilation plate 42 is fixed to the main structure 41 by glass glue. The baffle 3 is located between the dial plate 21 and the ventilation plate 42. The ventilation plate 42 is provided with a plurality of ventilation holes 421 for achieving indoor and outdoor air exchange. The baffle 3 is hingedly fixed to the main structure 41, so one end of the baffle 3 can rotate around the fixed end of the baffle 3.

[0049] like Figure 2When the cover plate 11 is buckled with the main structure 41, the pressing plate 12 will apply pressure to one end of the dial plate 21, so that one end of the dial plate 21 is pressed down. Since the dial plate 21 can rotate around the pin 22, the other end of the dial plate 21 is tilted, and the other end of the tilted dial plate 21 abuts against the baffle 3. Since the baffle 3 is located between the ventilation plates 42, the baffle 3 is close to the ventilation plates 42 under the pressure of the dial plate 21, and the ventilation holes 421 on the ventilation plates 42 can circulate air. When the baffle 3 is pressed against the ventilation plates 42, the baffle 3 blocks the ventilation holes 421, thereby cutting off the indoor and outdoor air, hindering the air circulation, and achieving the performance of heat preservation and heat insulation. When the cover plate 11 is gradually lifted, the pressure of the pressing plate 12 on one end of the dial plate 21 gradually decreases until it disappears, and the dial plate 21 will naturally become vertical under the action of gravity. As the other end of the dial plate 21 changes from tilting up to moving down, the effect of the other end of the dial plate 21 on the baffle 3 is also continuously reduced. Without the support of the dial plate 21, the baffle 3 also moves downward under the action of gravity, thereby opening the vent 421, and the indoor and outdoor air can be circulated and exchanged. The vent 421 is opened and closed by lifting and lowering the cover plate 11.

[0050] It is not difficult to find from the above content that the transmission device for opening and closing the ventilation plate of the unit curtain wall of the present invention includes: a rotating component 1, a transmission mechanism 2, a baffle 3 and a unit curtain wall 4. The rotating component 1 includes: a cover plate 11 and a pressure plate 12, the unit curtain wall 4 includes: a main structure 41 and a ventilation plate 42, and the transmission mechanism 2 includes: a dial plate 21 and a pin 22. The ventilation plate 42 is embedded in the main structure 41, and the ventilation plate 42 and the main structure are fixed by glass glue. A plurality of ventilation holes 421 are provided on the ventilation plate 42. The pressure plate 12 is located below the cover plate 11, and the pressure plate 12 is fixed on the cover plate 11 by threads. The dial plate 21 is located below the pressure plate 12, and the pin 22 is fixed on the dial plate 21, and the dial plate 21 can rotate in a plane around the pin 22. The baffle 3 is located between the dial plate 21 and the ventilation plate 42, and the baffle 3 is hinged to the main structure. In the transmission device for opening and closing the ventilation plate of the unit curtain wall of the embodiment of the present invention, the pressing plate 12 is fixed below the cover plate 11. When the cover plate 11 and the main structure 41 are in a gradually buckled state, the pressing plate 12 applies a certain pressure to the dial plate 21, so that one end of the dial plate 21 is pressed down. Since a pin 22 is fixed in the middle of the dial plate 21, the dial plate 21 can rotate in a plane, so the other end of the dial plate 21 is lifted. In the process of lifting the other end of the dial plate 21, the other end of the dial plate 21 abuts against the baffle 3, so that the position of the baffle 3 gradually moves up, and the baffle 3 moves toward the ventilation plate 42. Since the baffle 3 is located between the dial plate 21 and the ventilation plate 42, the baffle 3 will fit with the ventilation plate 42 under the action of the dial plate 21. Since the ventilation plate 42 is provided with a plurality of ventilation holes 421, the ventilation holes 421 are used for indoor and outdoor air exchange. When the baffle 3 is pressed on the surface of the ventilation plate 42, the vent is also blocked, thereby achieving the effect of blocking air circulation. When the cover plate 11 is gradually lifted, a gap is gradually formed between the cover plate 11 and the main structure 41. As the cover plate 11 is lifted, the position of the pressure plate 12 is gradually moved up. Since the plate 21 is no longer under the pressure of the pressure plate 12, the plate 21 naturally falls down under the influence of gravity. At the same time, the other end of the plate 21 changes from initially resisting the baffle 3 to being separated from the baffle 3. The baffle 3 is no longer resisted by the plate 21, and due to gravity, it shifts to one side and is separated from the ventilation plate 42. At this time, the vent is opened and air is exchanged and circulated. This transmission device realizes indoor and outdoor air circulation through mechanical transmission. When the cover plate 11 is lifted, the vent is opened and air is exchanged. When the cover plate 11 is lowered, the vent is closed. It is simple to operate, easy to install, cost-saving and stable in state, ensuring the normal working function of the vent as well as the thermal insulation and heat insulation performance.

[0051] Optionally, in this embodiment, the unit curtain wall 4 further includes a base 43. The base 43 is located on the left side of the cover plate 11. The base 43 is connected to the cover plate 11 through a rotating shaft. The cover plate 11 can rotate around the fixed end to facilitate the lifting and lowering of the cover plate 11. Since the cover plate 11 is fixed on the base 43, the cover plate 11 can be prevented from being lost during the lifting process.

[0052] Optionally, in this embodiment, it also includes: a stopper 5. Figure 3 The stopper 5 and the base 43 are both provided with threaded holes, and the stopper 5 is fixed to the base 43 by screws. Since the cover 11 can rotate around the base 43, excessive rotation will affect the service life of the cover 11. After adding the stopper 5, when the cover 11 rotates to a certain angle, due to the effect of the stopper 5, the cover 11 cannot continue to rotate at a larger angle, thereby protecting the cover 11 and extending its service life.

[0053] Optionally, in this embodiment, the reset mechanism 6 is located below the dial plate 21. The reset mechanism 6 includes: a bottom frame 61, a spring 62 and a rectangular ring 63. The rectangular ring 63 is fixed to the baffle 3, the bottom frame 61 is fixed to the structural body by glass glue, one end of the spring 62 is fixed to the rectangular ring 63, and the other end is fixed to the bottom cross frame. When the dial plate 21 presses the baffle 3 against the ventilation plate 42 by abutting against the rectangular frame, the spring 62 is in a stretched state. When the dial plate 21 falls freely, the baffle 3 leaves the ventilation plate 42 due to the action of the spring 62, so that the ventilation hole 421 is opened. When the pressure of the dial plate 21 on the baffle 3 is reduced, the tension of the spring 62 can prevent the baffle 3 from not leaving the ventilation plate 42, causing the ventilation hole 421 to fail to open. If the spring 62 is directly fixed on the baffle 3, the tension of the spring 62 for a long time will cause damage to the surface of the baffle 3, so a groove can be provided on the surface of the baffle 3, and the rectangular ring 63 can be slidably engaged in the groove. When the rectangular ring 63 is damaged, the rectangular ring 63 can be directly taken out and reinstalled for continued use, which greatly extends the service life of the baffle 3.

[0054] Optionally, in this embodiment, it further includes: a slide bar 7. A slide groove 611 is provided in the bottom frame 61, and the slide bar 7 is placed in the slide groove 611, and the slide bar 7 can slide in the slide groove 611. One end of the spring 62 is fixed to the rectangular ring 63, and the other end is fixed to the slide bar 7. As the tension of the spring 62 gradually changes, the position of the slide bar 7 in the slide groove 611 also changes continuously. After the fixed connection between the spring 62 and the bottom frame 61 is converted into a sliding connection, the service life of the bottom frame 61 is extended. If the slide bar 7 is damaged, a new slide bar 7 can be directly installed, thereby avoiding the situation of replacing the bottom frame 61.

[0055] Optionally, in this embodiment, a rubber sealing pad 8 is fixed on the side of the baffle plate 3 that contacts the ventilation plate 42. Since the ventilation plate 42 and the baffle plate 3 are both made of aluminum alloy, the rubber sealing pad 8 can be installed on the baffle plate 3 to completely block air circulation when in contact.

[0056] Optionally, in this embodiment, one end of the paddle plate 21 is pressed down by the pressing plate 12, so that the other end of the paddle plate 21 is tilted so that the other end of the paddle plate 21 abuts against the rectangular ring 63. Since both the paddle plate 21 and the rectangular ring 63 are made of aluminum alloy, direct contact and pressure with the metal surface can easily cause damage to the metal surface, so a rubber head 211 is installed at the end of the paddle plate 21 abutting against the rectangular ring 63. The rubber head 211 has a certain buffering capacity and is soft and wear-resistant, which reduces the friction with the surface of the rectangular ring 63 and prolongs its service life.

[0057] Optionally, in this embodiment, the locking mechanism 9 is located on the surface of the main structure 41, and a protrusion 111 is provided on the surface of the cover plate 11, and the protrusion 111 is located on the left side of the locking mechanism 9. The locking mechanism 9 includes: a fixed block 91 and a locking ring 92. A through hole is provided in the middle of the fixed block 91, and the locking ring 92 passes through the through hole and is slidably connected with the fixed block 91. The protrusion 111 is located on the left side of the fixed block 91, and the locking ring 92 can be sleeved on the protrusion 111, so that the protrusion 111 is surrounded by the locking ring 92. The locking ring 92 can prevent the cover plate 11 from being lifted without knowing it, thereby maintaining the closed state of the ventilation hole 421 and preventing air from entering the room.

[0058] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact via an intermediate medium.

[0059] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
