Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
Referring to fig. 1 to 2, an embodiment of the present invention provides a multifunctional open-close deformable ceiling, which includes a rigid bracket 1, a first panel 2, a second panel 3, a swing arm 4, a telescopic sliding rail 5 and a locking device 6; the rigid support 1 is arranged on the building roof, a telescopic slide rail 5 is arranged between the back side of the first panel 2 and the rigid support 1 along the vertical direction, and the telescopic slide rail 5 is provided with a fixed section fixedly connected with the rigid support 1 and a telescopic section fixedly connected with the first panel 2, so that the first panel 2 is in sliding connection with the building roof through the telescopic slide rail 5; one side edge of the second panel 3 is hinged with the side edge of the first panel 2, and the first panel 2 and the second panel 3 are spliced into a complete panel in a tiled state; the back side of the second panel 3 is hinged with the bottom end of the swinging arm 4, and the upper end of the swinging arm 4 is hinged with the rigid bracket 1; a locking device 6 is arranged on the telescopic slide rail 5 or between the first panel 2 and the rigid support 1, so that the first panel 2 and the second panel 3 are locked and fixed when being tiled.
When closed, the first panel 2 and the second panel 3 are tiled and opened, and are spliced to form a complete ceiling surface. At this time, the locking device 6 locks the first panel 2 so that it does not slide downward by its own weight. When the access hole is required to be opened, the first panel 2 can be opened by sliding downwards along the vertical direction under the action of the telescopic sliding rail 5, then the second panel 3 can be opened under the action of the first panel 2 and the swinging arm 4, and finally the second panel 3 is vertical, so that an empty area with the same area as the second panel 3 is emptied. In the opening and closing process, the second panels 3 are linked through the mechanism, no manual special operation is needed, an operator only needs to operate the first panel 2, and the opening and closing linkage is smooth.
Such a variation may be applied to alter the shape of a suspended ceiling, as an access opening, or for fire fighting applications.
When used as an access opening, the second panel 3 is folded to leave an empty control area for access by an operator. Here, the areas of the first panel 2 and the second panel 3 are not limited, and the areas of the two may be unequal. Since the empty area of the access opening is equal to the area of the second panel 3 after opening, the area of the second panel 3 can be increased completely in order to strive for a larger access space. However, the area of the second panel 3 may be increased, which may increase the movement range of the first panel 2 during opening and closing, and may also increase the length of the swing arm 4.
Preferably, the swing arm 4 has a long rod shape, and its bottom end is hinged to two sides of the back side of the second panel 3. The use of a long bar as the swivel arm 4 can provide further material savings. In addition, the hinge point of the swing arm 4 and the second panel 3 is not necessarily located at the outer side of the second panel 3, and may be located at two sides of a certain position in the middle of the second panel 3. The resulting effects are: the length of the swinging arm 4 can be further shortened, and the movable stroke of the first panel 2 in the opening and closing process can be shortened; at the same time, it is also possible to extend a part of the second panel 3 above the frame after the second panel 3 has been opened. Therefore, the space occupation in the opening and closing process can be further saved.
After the second panel 3 is opened, the first panel 2 and the second panel 3 are arranged at a certain angle or even at a right angle to form a three-dimensional shape, so that the invention can also be applied to changing the appearance of the ceiling.
In addition, when the second panel 3 is folded and unfolded, the suspended ceiling and the roof of the building are in an open structure. When fire-fighting dangerous situations occur, the structure can be utilized to realize the discharge of smoke and reduce the smoke concentration in the building, thereby preventing the suffocation of personnel in the building to a certain extent and improving the survival chance of the personnel in the building. Specifically, the locking device 6 may be connected to a fire protection system, and when the fire protection system detects a fire, the fire protection system automatically controls the locking device 6 to open the first panel 2 and the second panel 3. Details of the specific technical scheme used for fire protection will be described in detail below.
The arrangement of the second panel 3 has two structures: one second panel 3 is hinged to one side of the first panel 2 to form a single-side overturning structure; or two second panels 3 are respectively hinged on two sides of the first panel 2 to form a two-side turnover structure.
When used as an access opening or for fire fighting purposes, the second panel 3 naturally only needs to be mounted on one side of the first panel 2 to meet the requirements. However, if used to change the ceiling shape to effect the appearance change, a single second panel 3 is not necessarily required. The two second panels 3 are folded in a mirror direction at the two sides of the first panel 2, so that the appearance modeling can be more coordinated. Meanwhile, in order to ensure that the joint of the first panel 2 and the second panel 3 at the hinge side is more attractive after folding, preferably, the two side walls of the second panel 3 and the first panel 2 at the hinge side are respectively provided with chamfers matched with each other, so that the side walls of the second panel 3 cannot be propped up and dead when the second panel 3 rotates from the first panel 2, and the chamfers of the first panel 2 and the second panel 3 are mutually spliced to form a seamless appearance after folding.
In order to prevent the second panel 3 from being closed again, the swing arm 4 and the second panel 3 are completely straightened and topped up, preferably, the horizontal position of the hinge point at the upper end of the swing arm 4 is located within the side line of the hinge side of the first panel 2. When the second panel 3 is opened vertically, the swing arm 4 extends obliquely inwards, and forms a certain included angle with the second panel 3.
In order to facilitate the opening and closing operation of the second panel 3 when the door is used as an access opening, the locking device 6 is preferably a push-type rebound device, which can be opened by pushing and then closed by pushing. Therefore, the maintenance opening does not need to be provided with a handle and does not need to be opened or closed by other tools, and is a preferable manual control scheme.
Referring to fig. 3, the locking device 6 specifically includes a base 7, and a sliding block 8 slidably connected to the base 7; the base 7 is provided with a sliding groove 10 extending along the sliding direction, and the tail end of the sliding groove 10 is provided with a stop block 9 which divides the end part of the sliding groove 10 into an inlet groove 11 and an outlet groove 12; the stop block 9 is heart-shaped, the tip end of the stop block faces the middle direction of the sliding groove 10 and is biased to one side of the sliding groove 10, so that the tail end of the sliding groove 10 is opposite to a first inclined surface 13 on one side of the stop block 9, and the first inclined surface 13 is parallel to the inlet groove 11; the back side of the stop block 9 is provided with a second inclined plane 14 opposite to the tip end of the stop block 9, one side of the second inclined plane 14 away from the inlet groove 11 is provided with a second flange 17, the rear end of the inlet groove 11 extends obliquely inwards, and the tail end of the inlet groove is provided with a first flange 16 pointing to the middle part of the second inclined plane 14 of the stop block 9; a third inclined surface 15 positioned on the other side of the stop block 9 is parallel to the outlet groove 12, the rear end of the outlet groove 12 extends inwards and obliquely to be connected with the rear end of the inlet groove 11 and is opposite to the second inclined surface 14, and the front end of the outlet groove 12 is connected with the sliding groove 10; the sliding block 8 is provided with a clamping column 18 which can swing left and right on the sliding block 8, and the clamping column 18 slides along the guide of the sliding groove 10 and can swing along the inlet groove 11 and the outlet groove 12; the sliding block 8 and the base 7 are respectively fixedly connected with the fixed section and the telescopic section of the telescopic sliding rail 5.
The working principle is as follows: when the second panel 3 needs to be opened, the first panel 2 is pressed down, and the sliding block 8 is driven to slide upwards for a small distance, and the clamping column 18 originally locked between the second inclined surface 14 and the second blocking edge 17 of the stop block 9 slides along the outlet groove 12 and reenters the sliding groove 10, so that the sliding block can slide freely in the vertical direction.
When the second panel 3 needs to be closed, only the first panel 2 needs to be pushed upwards to drive the sliding block 8 to slide upwards, and the clamping column 18 slides upwards to the rearmost end along the sliding groove 10. With the pressing of the first panel 2 by the service personnel, the clamping post 18 slides to the inlet groove 11 under the guiding action of the first inclined surface 13 of the stop block 9. After the operator releases the pressing, the clamping post 18 slides to the surface of the second inclined plane 14 again along the inward inclination of the rear end of the inlet groove 11, and the clamping post 18 is clamped on the second flange 17 under the guidance of the second inclined plane 14, so that the whole first panel 2 is fixed.
It should be noted that the sliding block 8 and the base 7 are mutually acted, and the fixed section of the telescopic sliding rail 5 can achieve the above effects and are equivalent in principle no matter being connected with the sliding block 8 or the base 7. The whole locking device 6 is not limited in material, and can be manufactured by a mold in theory using a plastic material, so that the cost is low.
Example two
The embodiment mainly introduces the technical scheme details of the invention when the fire-fighting device is used for fire-fighting functions.
In order to cooperate with the fire fighting function, it may also be preferable to provide a smoke evacuation system (not shown) between the first panel 2 and the roof of the building. When the first panel 2 and the second panel 3 are opened for fire protection, the smoke evacuation system will be opened to cooperate with the smoke evacuation. The smoke exhaust system can be a fan structure for actively exhausting air, and can also be in other structural forms, and the specific structure is not described herein.
The use of a push-down type rebound device as the locking means 6 as in the first embodiment is applicable to manual solutions. If the fire protection function is to be satisfied, an automatic unlocking action can be realized under the control of a power failure or an electronic system, and the locking device 6 is preferably an electromagnetic lock 22. Referring to fig. 4 to 5, a magnet block 23 matched with the electromagnetic lock 22 is disposed on the first panel 2 or the telescopic section of the telescopic slide rail 5, so that the electromagnetic lock 22 is electrified to attract the magnet block 23. The electromagnetic lock 22 has the advantages of high suction force and low power consumption. In normal use, the electromagnetic lock 22 is energized and attracted, thereby locking the first panel 2. When fire-fighting dangerous situations occur, the fire-fighting system can actively control the power-off, or under the condition that the extremely severe circuit system is completely powered off, the electromagnetic lock 22 is powered off to unlock, and the first panel 2 slides downwards under the action of dead weight, so that the second panel 3 is opened, and the fire-fighting smoke discharging effect is achieved.
When the first panel 2 falls, it is typically required to be manually pushed to reclose it. In order to automate the lifting of the first panel 2, in particular when the first panel 2 is reset to the closed position after falling, the invention preferably also comprises an electric lifting system. The electric lifting system comprises a motor, a synchronous shaft 19, a belt pulley 20, a driving belt 21 and a connecting member; the synchronizing shafts 19 are provided with an upper synchronizing shaft and a lower synchronizing shaft, the motor is in transmission connection with one synchronizing shaft 19, the synchronizing shafts 19 are in transmission connection with belt wheels 20, the belt wheels 20 on the same side are in winding connection with a driving belt 21, and the connecting members are connected between the driving belt 21 and the first panel 2, so that the driving belt 21 can drive the first panel 2 to slide up and down.
The motor rotates to finally drive the driving belt 21 to rotate, and the driving belt 21 which is in up-down winding connection can drive the first panel 2 to move up and down, so that the automation degree of the invention is further improved. In addition, if a plurality of groups of multifunctional open-close deformed ceilings of the invention are installed in the whole suspended ceiling system, the linkage among a plurality of groups of first panels 2 can be completely realized.
The multifunctional open-close deformed ceiling provided by the invention has multiple functions, and can be used as a ceiling access opening, change the shape of the ceiling or be used for fire-fighting functions. When the ceiling access opening is used as the ceiling access opening, the occupied space in the opening and closing process is smaller, interference with other parts is not easy, and access of access personnel is facilitated. The unique pressing locking structure makes the outer parts have no handles and other members, and the appearance of the ceiling is easy to keep consistent with that of a common ceiling, and the ceiling has high aesthetic degree. The folded structure can also be used to change the shape of the ceiling to give the appearance of two forms. Can be opened when a fire disaster dangerous case occurs, which helps smoke discharge, improves the survival chance of personnel in the building and realizes the fire-fighting function. And has two structures of manual operation and automatic operation, thereby meeting different requirements.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
