Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, and in particular to a ventilation device for building design. Background Technology

[0002] Architectural design refers to the process by which designers, before construction begins, comprehensively envision the problems that may exist or occur during the construction and use of a building, formulate solutions and plans, and express them in drawings and documents.

[0003] Ventilation equipment is a crucial part of building design. Ventilation, also known as air exchange, involves mechanically or naturally introducing sufficient fresh air into an indoor space to ensure air circulation. Currently, most ventilation equipment involves installing exhaust fans on buildings for ventilation operations, with filter plates installed at the air inlet of the exhaust fans. These filter plates filter the air entering the exhaust fans, preventing impurities from being drawn into the indoor space. In existing technology, bolts are typically used to install the filter screen and the exhaust fan. However, because the exhaust fan vibrates during operation, the bolts can easily loosen under continuous vibration, leading to a loosening of the filter screen and affecting its ability to intercept impurities in the air. Summary of the Invention

[0004] Therefore, it is necessary to provide a ventilation device for building design to address the problem that exhaust fans generate vibrations during operation, which can easily lead to loose bolts under continuous vibration, thereby loosening the filter screen and affecting the filter screen's ability to intercept impurities in the air.

[0005] The device includes: a ventilation duct with an exhaust fan installed at one end; a filter mechanism including a filter plate with two threaded holes on its surface; a ring fixedly connected to the end of the exhaust fan away from the ventilation duct; an installation groove on the end of the ring away from the exhaust fan; bolts threadedly connected to both sides of the inner wall of the ring; a round rod slidably connected to the inner wall of the bolts and nuts; a second magnetic block fixedly connected to one end of the round rod; and two limiting grooves on the surface of the ring with a first magnetic block fixedly connected to one end of the inner wall of each limiting groove.

[0006] In one embodiment, two fixing rings are fixedly connected to the surface of the circular ring. The two fixing rings and two bolts are located on the same axis, and the two bolts are located inside the two fixing rings respectively. The inner wall of the fixing ring has multiple grooves arranged in a ring. The grooves in the inner wall of the fixing ring increase the resistance to reverse rotation of the bolts during the fixing process, which helps to enhance the stability of the bolts during the fixing process.

[0007] In one embodiment, the surface of the round rod is provided with multiple annular grooves, which are evenly distributed horizontally. This increases the friction between the surface of the round rod and the inner wall of the bolt / nut and the inner wall of the limiting groove, thereby increasing the resistance to horizontal movement of the round rod, enhancing the stability when the first and second magnetic blocks are attracted, and ensuring the stability of the round rod when limiting the bolt.

[0008] In one embodiment, two locking blocks are fixedly connected to one end of the inner wall of the mounting groove, and two locking slots are formed on the surface of the filter plate. The locking slots and blocks help to limit the installation position of the filter plate in the mounting groove, facilitating the filter plate's entry into the mounting groove. The two threaded holes are respectively aligned with two bolts.

[0009] In one embodiment, the end of the locking block furthest from the mounting slot is curved, and one end of the slot is flared. This facilitates better insertion of the locking block into the slot.

[0010] In one embodiment, a retaining plate is fixedly connected to the lower end of the surface of the round rod, and a through groove is formed at the lower end of the surface of the fixing ring. The retaining plate and the through groove limit the movement of the round rod, preventing it from rotating during the limiting process and enhancing its stability.

[0011] In one embodiment, two tie rods are fixedly connected to the end of the filter plate away from the mounting groove, and the two tie rods are symmetrical about the center of the filter plate. When the filter plate is assembled or disassembled, the two tie rods provide a fulcrum for the operator to operate the filter plate, making it easier to put the filter plate in or take it out. Beneficial effects

[0012] 1. In the above-mentioned filtration mechanism, the filter plate is installed by bolts and threaded holes. When the bolts are threaded into the threaded holes, the groove opened on the inner wall of the fixing ring helps to increase the resistance to reverse rotation of the bolt during the fixing process. The round rod is engaged with the nut of the bolt and the corresponding limiting groove, which helps to limit the bolt and prevent the bolt from rotating during the fixing process. In addition, during the limiting process, the round rod is limited by the attraction of the first magnetic block and the second magnetic block, which helps to ensure the stability of the round rod when limiting the bolt. This ensures the stability of the bolt fixing the filter plate during the use of the device, prevents the filter plate from loosening, and thus ensures the filter plate's interception effect on impurities in the air.

[0013] 2. The annular groove on the surface of the round rod helps to increase the friction between the surface of the round rod and the inner wall of the bolt and nut and the inner wall of the limiting groove, thereby increasing the resistance to the horizontal movement of the round rod, strengthening the stability when the first magnetic block and the second magnetic block are attracted, and ensuring the stability of the round rod when limiting the bolt.

[0027] The following is combined Figures 1-5 This utility model describes a ventilation device for building design.

[0028] In one embodiment, a ventilation device for building design includes: a ventilation duct 100, with an exhaust fan 200 installed at one end of the ventilation duct 100; a filter mechanism 300, including a filter plate 310, the surface of the filter plate 310 having two threaded holes 311; a ring 320 fixedly connected to the end of the exhaust fan 200 away from the ventilation duct 100, the end of the ring 320 away from the exhaust fan 200 having an installation groove 321; bolts 330 threadedly connected to both sides of the inner wall of the ring 320; a round rod 350 slidably connected to the inner wall of the bolt 330 nut; a second magnet 351 fixedly connected to one end of the round rod 350; and two limiting grooves 322 opened on the surface of the ring 320, with a first magnet 323 fixedly connected to one end of the inner wall of the limiting groove 322.

[0029] In this embodiment, when using the device for ventilation, the end of the ventilation pipe 100 away from the exhaust fan 200 is installed to the wall. A commonly used installation method in the prior art can be adopted. After installation, when ventilation is performed, the exhaust fan 200 is started by the controller, so that the exhaust fan 200 sends the external air into the room.

[0030] The nut of bolt 330 has a hexagonal hole in the middle. The operator can use an Allen wrench that matches the hexagonal hole to turn bolt 330. When filter plate 310 is placed into mounting groove 321, the outer surface of filter plate 310 fits with the inner surface of mounting groove 321. Threaded hole 311 matches bolt 330. The connection between nut of bolt 330 and round rod 350 is located at the eccentric part of bolt 330.

[0031] When the two round rods 350 are inserted into the two limiting grooves 322 respectively, the surface of the round rods 350 is in contact with the inner wall of the limiting grooves 322, and the magnetic poles of the first magnetic block 323 and the corresponding second magnetic block 351 are opposite. Therefore, the first magnetic block 323 and the corresponding second magnetic block 351 will attract each other when they come into contact.

[0032] like Figure 3 and Figure 4 As shown, two fixing rings 340 are fixedly connected to the surface of the ring 320. The two fixing rings 340 and two bolts 330 are located on the same axis. The two bolts 330 are located on the inner side of the two fixing rings 340 respectively. The inner wall of the fixing ring 340 is provided with a plurality of annularly distributed grooves 341.

[0033] In this embodiment, the outer surface of the bolt 330 nut is in contact with the inner wall of the retaining ring 340, the groove 341 is a strip groove, and the center of the two bolts 330 coincides with the center of the two retaining rings 340 respectively.

[0034] like Figure 4As shown, the surface of the round rod 350 is provided with multiple annular grooves 352, which are evenly distributed in the horizontal direction.

[0035] In this embodiment, when the round rod 350 is inserted into the nut and limiting groove 322 of the bolt 330, the surface of the round rod 350 with the annular groove 352 contacts the inner wall of the nut and the inner wall of the limiting groove 322.

[0036] like Figure 3 Figure 5 As shown, two locking blocks 324 are fixedly connected to one end of the inner wall of the mounting groove 321, and two locking slots 312 are opened on the surface of the filter plate 310. The end of the locking block 324 away from the mounting groove 321 is curved, and the opening of one end of the locking slot 312 is funnel-shaped.

[0037] In this embodiment, when the filter plate 310 is placed into the mounting groove 321, the end of the slot 312 with the opening in the shape of a pull plate faces the block 324. When the block 324 enters the slot 312, the surface of the block 324 fits against the inner wall of the slot 312. And when the filter plate 310 cannot move further after entering the mounting groove 321, the two threaded holes 311 are respectively aligned with the two bolts 330.

[0038] It should be noted that when one of the card blocks 324 coincides with the corresponding card slot 312, the other card block 324 coincides with the other card slot 312.

[0039] like Figure 4 As shown, a clamping plate 360 ​​is fixedly connected to the lower end of the surface of the round rod 350, and a through groove 342 is provided on the lower end of the surface of the fixing ring 340.

[0040] In this embodiment, after the rotating bolt 330 completes the threaded connection with the corresponding threaded hole 311, the bolt 330 can no longer rotate. At this time, the connection between the nut of the bolt 330 and the round rod 350 is aligned with the corresponding limiting groove 322. Then, after the round rod 350 is inserted into the nut of the bolt 330 and the corresponding limiting groove 322, the retaining plate 360 ​​will enter the through groove 342. One end of the retaining plate 360 ​​is pressed against one end of the inner wall of the through groove 342, and both sides of the retaining plate 360 ​​are in contact with both sides of the inner wall of the through groove 342.

[0041] like Figure 2 As shown, two pull rods 313 are fixedly connected to the end of the filter plate 310 away from the mounting groove 321, and the two pull rods 313 are symmetrical about the center of the filter plate 310.

[0042] In this embodiment, when disassembling and assembling the filter plate 310, the operator can drive the filter plate 310 to move using two pull rods 313.

[0043] Working principle: When installing the filter plate 310, place the filter plate 310 into the mounting groove 321, and align the two slots 312 on the surface of the filter plate 310 with the two locking blocks 324 respectively. After alignment, push the filter plate 310 horizontally into the mounting groove 321. The locking blocks 324 engage with the slots 312, and the two threaded holes 311 align with the two bolts 330 respectively. At this time, the operator uses an Allen wrench to turn the bolts 330, so that the two bolts 330 are threadedly connected to the two threaded holes 311 respectively. When the bolts 330 are turned... After the threaded connection with the corresponding threaded hole 311 is completed, when the bolt 330 can no longer rotate, insert the two round rods 350 into the nuts of the corresponding bolt 330 and the corresponding limiting grooves 322 respectively. The round rods 350 limit the bolt 330. After the round rods 350 are inserted, the first magnetic block 323 and the corresponding second magnetic block 351 in the limiting groove 322 attract each other to limit the round rods 350. At this time, the installation of the filter plate 310 is completed. When the exhaust fan 200 performs ventilation operation, the filter plate 310 filters impurities in the air.

[0044] It should be noted that the exhaust fan 200 and other components mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the exhaust fan 200 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
