Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust ventilation ducts, and in particular to an integrated device for connecting and installing air ducts. Background Art

[0002] Air ducts, also known as ventilation ducts, are piping systems used for air delivery and distribution. According to the cross-sectional shape, air ducts can be divided into circular ducts, rectangular ducts, oblate ducts, and many other types. Rectangular ducts are relatively simple to manufacture and have low costs. They are mostly used in supermarkets, indoor stadiums, cinemas, and other buildings. In the prior art, rectangular ducts are mostly connected by flanges.

[0003] In the prior art, during general air duct installation, workers who install and connect the air duct on the ceiling first pre-install the device for hanging the air duct on the ceiling, then connect the air duct on the ground, and then install the air duct on the hanging device. However, the air duct is long after being connected, which is not conducive to workers working in mid-air. Therefore, there are other installation methods, such as directly installing sections of air duct on the hanging device first, and then connecting the flanges with bolts, or connecting several sections of air duct into one section on the ground, and then installing this section of air duct on the hanging device for connection. However, these solutions require workers to stand on a lifting mechanism, rise to mid-air, and use hand-held tools to connect the flanges of the air duct with bolts.

[0004] This installation and connection method is acceptable on the ground, but in mid-air, when workers use bolts to connect flanges, there is little room for movement, so there will be problems with inconvenient operation, which in turn affects work efficiency. In addition, if maintenance is required in the future, workers will have to dismantle the problematic air duct for inspection. Moreover, since the two sections of the air duct need to be connected by flanges, disassembly will also cause inconvenience in repeated installation operations. Therefore, the existing air duct installation and connection has the problems of inconvenient operation and low installation and disassembly efficiency. Therefore, it is necessary to provide a solution to solve the above problems. Utility Model Content

[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 as well as Figure 3 As shown, according to an embodiment of the utility model, a duct connection and installation integrated device includes a rectangular sleeve 1000, and a plurality of plug-in components 3000 arranged around the four sides of the rectangular sleeve 1000 and the side wall of the air duct 2000, wherein the plug-in component 3000 is used to detachably install the air duct 2000 on the rectangular sleeve 1000; the two end faces of the rectangular sleeve 1000 are provided with card grooves for accommodating the ends of the air duct 2000, and sealing rings are provided in the card grooves; the middle part of the rectangular sleeve 1000 is connected to an installation component 1200 for fixing the rectangular sleeve 1000 on the ceiling. By using the above-mentioned mechanism, the installation and connection of the air duct 2000 are integrated. It is only necessary to first install the installation component 1200 under the ceiling, and then the air duct 2000 with the plug-in component 3000 at the end can be directly inserted into the rectangular sleeve 1000 suspended on the installation component 1200, and locked to complete the installation and connection of the air duct 2000 under the ceiling. This solves the problem of inconvenient operation and low installation and disassembly efficiency of the air duct 2000 connected by flanges in the prior art. Through the provided card slot and the sealing ring in the card slot, the end of the air duct 2000 is inserted into the card slot and abuts against the side of the sealing ring, thereby solving the sealing problem between the air ducts 2000.

[0027] Further, such as Figure 1 and Figure 3 As shown, each of the plug-in components 3000 includes a first plug-in mechanism and two second plug-in mechanisms, the two second plug-in mechanisms are arranged symmetrically with respect to the first plug-in mechanism, the first plug-in mechanism is fixedly mounted on the side of the rectangular sleeve 1000, and the two second plug-in mechanisms are respectively fixedly connected to the side walls of the two sections of the air duct 2000. By plugging the first plug-in mechanism and the second plug-in mechanism together, the flange connection of the prior art is replaced, and the connection method between the air ducts 2000 is simplified, thereby improving the connection efficiency.

[0028] Further, such as Figure 3 and Figure 4As shown, the first plug-in mechanism and the second plug-in mechanism both include a housing 3100, a cavity is provided in the housing 3100, one end of the housing 3100 of the second plug-in mechanism protrudes to form an insert block 3200, the insert block 3200 has a guide surface 3210, a first opening 3220 is further provided on the housing 3100, the first opening 3220 is adjacent to the guide surface 3210, so that the housing 3100, the first opening 3220 and the guide surface 3210 form a plug hole, and a second locking assembly is provided in the insert block 3200 of the second plug-in mechanism;

[0029] like Figure 3 and Figure 5 as well as Figure 7 As shown, at both ends of the first plug-in mechanism, there is a plug-in block 3200 with the same structure as the first plug-in mechanism. The two plug-in blocks 3200 of the first plug-in mechanism are centrally symmetrically arranged. The plug-in block 3200 of the first plug-in mechanism is also provided with a first locking assembly, such as Figure 5 As shown, the plug blocks 3200 of the first plug-in mechanism and the second plug-in mechanism can be slidably inserted into the plug holes of the other party along the guide surface 3210. Through the above mechanism, the plug blocks 3200 and the plug holes are respectively arranged in the first plug-in mechanism and the second plug-in mechanism, and a locking assembly is arranged between the plug blocks 3200. The plug blocks 3200 are inserted into the plug holes to complete the plug-in. The first and second locking assemblies fix the plug-in to ensure the stability between the air duct 2000 and the rectangular sleeve 1000. In addition, the plug blocks 3200 are arranged at both ends of the first plug-in mechanism to achieve a stable connection between the air ducts 2000 at both ends of the rectangular sleeve 1000.

[0030] Further, such as Figures 3 to 9 As shown, the middle of the guide surface 3210 is recessed into the cavity of the housing 3100 to form a limiting semicircular ring 3211, and the first locking assembly and the second locking assembly both include a return spring 3212 and a semicircular rotating block 3213, and the semicircular rotating block 3213 is rotatably installed in the limiting semicircular ring 3211. Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the two semicircular rotating blocks 3213 of the first plug-in mechanism are provided with limiting protrusions 3214, and the two limiting protrusions 3214 are connected via a return spring 3212. Figure 6As shown, the second locking assembly further includes a control rod 3215, one end of which is fixedly connected to the semicircular rotating block 3213 of the second locking assembly, and the other end of which extends out of the housing 3100 of the second plug-in mechanism. One end of the return spring 3212 of the second plug-in mechanism is connected to the inner wall of the housing 3100 of the second plug-in mechanism, and the other end is connected to the middle of the control rod 3215; Figure 8 and Fig. 9 As shown, the limiting semicircular ring 3211 is provided with a second opening 3116 for the limiting protrusion 3214 and the control rod 3215 to move. Figure 6 As shown, the housing 3100 is provided with a third opening 3110 for the control rod 3215 to move.

[0031] like Figure 5 and Figure 6 As shown, by utilizing the return of the spring, the semicircular rotating block 3213 can be provided with the function of returning to its original position after being pushed, and at the same time, a limiting protrusion 3214 is provided that passes through the limiting semicircular ring 3211 and is slidably connected to the limiting semicircular ring 3211 to limit the semicircular rotating block 3213 to slide inside the limiting semicircular ring 3211. The two ends of the return spring 3212 connect the two semicircular rotating blocks 3213 in the first plug-in mechanism, which simplifies the structure while allowing the two semicircular rotating blocks 3213 in the first plug-in mechanism to interfere with each other's rotation, so that the two semicircular rotating blocks 3213 can obtain a greater return-to-original-position force after being pushed and rotated by the semicircular rotating blocks 3213 in the second plug-in mechanism, thereby increasing the locking effect of the locking assembly.

[0032] like Figure 6 As shown, a control rod 3215 is also provided on the second locking assembly of the second plug-in mechanism. By toggling the control rod 3215, the rotation of the semicircular rotating block 3213 in the second locking assembly can be operated, thereby synchronously controlling the first locking assembly inside the first plug-in mechanism to release the locking state between the first and second locking assemblies. In this way, the air duct 2000 can be pulled out of the first plug-in mechanism to complete the disassembly, thereby achieving the effect of simple installation and disassembly of the air duct 2000.

[0033] Further, such as Figure 5 , Figure 6 to Figure 7 As shown, the return springs 3212 of the first locking assembly and the second locking assembly are both in a stretched state in the initial state. Figure 5 The semicircular rotating block 3213 shown in the figure all protrudes from the limiting semicircular ring 3211, so that when the first plug-in mechanism and the second plug-in mechanism slide toward each other, the semicircular rotating block 3213 is subjected to the force of the plug-in block 3200 and rotates. Figure 7 As shown, the semicircular rotating block 3213 is rotated so that the semicircular rotating block 3213 is partially inserted into a partial area of ​​another relative limiting semicircular ring 3211, and the locking assembly can be locked by the mutual locking.

[0034] Further, such as Figure 1 , Figure 3 and Fig.10 As shown, the installation assembly 1200 includes a top plate 1210 and a connecting rope 1220 vertically fixed to the top plate 1210. The top plate 1210 is also provided with bolts and screw holes. The top plate 1210 is fixedly connected to the lower surface of the ceiling by bolts. One end of the connecting rope 1220 is fixed to the lower bottom surface of the top plate 1210, and the other end is fixed to the side of the rectangular sleeve 1000 relative to the top plate 1210. During the installation process, since the ports of the air duct 2000 where the first plug-in mechanism rectangular sleeve 1000 and the second plug-in mechanism are installed have forward plug blocks 3200, the connecting rope 1220 is selected to connect the top plate 1210 with the rectangular sleeve 1000. The flexibility of the connecting rope 1220 allows the air duct 2000 to be connected and installed in an integrated manner. While being stably connected to the ceiling, it can also appropriately change its position relative to the air duct 2000, so that the positions of the two plug-in mechanisms will not interfere with each other and affect the plug-in, which is convenient for the workers' work and can also provide a shock-absorbing effect.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
