Description

Technical Field

[0001] The present application relates to the technical field of air duct installation, and in particular to an air duct installation device. Background Art

[0002] The air duct is a system used for air delivery and distribution. There are two types: inorganic air duct. The air duct is made by applying (such as neutral glass glue) on the gaps such as the bite seam, rivet seam, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, the air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types. Among them, the circular air duct has the smallest resistance but the largest height dimension and is complex to make, so the rectangular air duct is mainly used. The air duct is generally suspended and fixed on the lower end surface of the top plate through a matching installation device, so as not to affect the use of the interior space of the building.

[0003] When installing existing air ducts, support brackets are generally pre-installed on the lower end surface of the structural top plate, and then the air duct is lifted and overlapped on the support brackets. This connection method allows the air duct and the support brackets to slide relative to each other. The support brackets themselves cannot play a positioning role for the air duct. After the air duct is overlapped, it is necessary to move it to adjust the position so that the currently installed air duct section is in a preset position. This adjustment process is relatively time-consuming and labor-intensive, and is not conducive to efficient installation of the air duct. Therefore, an air duct installation device is proposed to address the above problems. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides an air duct installation device that overcomes the shortcomings of the prior art and aims to solve the problem that the air duct support brackets lack guiding and positioning measures during the installation process, resulting in the air duct needing precise position adjustment after overlapping, making the installation more time-consuming and labor-intensive.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] The air duct installation device includes a support bracket and a ventilation duct main body erected therein, the lower end surface of the ventilation duct main body is welded with an end clamping strip, the support bracket includes a main support plate, the two ends of the upper end surface of the main support plate are fixedly provided with hangers, the two side surfaces of the main support plate are fixedly provided with hinge seats, side support plates are rotatably provided between the hinge seats via a rotating connecting shaft, the end of the rotating connecting shaft extends out of the hinge seat and is sleeved with a torsion spring, an upper fixed plate is slidably provided on the upper part of the hanger, lateral limit strips are fixedly provided on both sides of the lower end surface of the upper fixed plate, and the upper part of the hanger is located above the upper fixed plate and is threadedly connected with a fastening nut.

[0007] As a preferred technical solution of the present application, one end of the torsion spring is fixedly connected to the side surface of the side support plate, and the other end of the torsion spring is fixedly connected to the end of the rotating connecting shaft.

[0008] By adopting the above-mentioned technical solution, the side support plate can be in a raised state when not under the squeeze of the ventilation duct body, so that the width of the overall structure is reduced to a certain extent, and the space occupied by the overall installation structure can be reduced to a certain extent. At the same time, it is also convenient for the placement of the ventilation duct body, so that there is no need for more detailed positioning to ensure that the side support plates on both sides are located in the two end clips.

[0009] As a preferred technical solution of the present application, the lower side of the end of the side support plate is chamfered to form a full-length support plate groove.

[0010] By adopting the above technical solution, it is possible to prevent the corners of the side support plate, which are originally relatively sharp, from getting stuck when contacting the end clamping strip, thereby preventing the side support plate from rotating.

[0011] As a preferred technical solution of the present application, a card interface that matches the cross-sectional size of the suspension rod is opened on the side surface of one end of the upper fixing plate, and a reverse card interface is opened on the other end of the upper fixing plate.

[0012] By adopting the above technical solution, the post-installation of the upper fixing plate can be facilitated without having to sleeve it on the suspension rod in advance, which can facilitate the installation work.

[0013] As a preferred technical solution of the present application, the inner side of the bottom of the lateral limit strip is chamfered to form a continuous limit strip groove.

[0014] By adopting the above technical solution, the groove of the limit strip can play a guiding role. When installing the fixing plate, the groove of the limit strip can be used to guide the lateral limit strips to be stuck on both sides of the ventilation duct body, thereby improving the installation efficiency and fixing effect.

[0015] As a preferred technical solution of the present application, the end clip includes a clip body, the inner side of the bottom of the clip body is chamfered to form a full-length clip groove, and a rubber fixing layer is fixedly attached to the inner side of the clip body.

[0016] By adopting the above technical solution, the groove of the clamping strip can guide the side support plate, making it easier for the side support plate to enter the inner space of the end clamping strip, and the rubber fixing layer can play a supporting role by closely contacting the end of the side support plate through its own deformation, while not hindering its normal rotation.

[0017] As a preferred technical solution of the present application, a continuous reinforcing plate is welded along the length direction at the middle portion of the lower end surface of the main support plate.

[0018] By adopting the above technical solution, the overall load-bearing capacity of the main support plate can be enhanced, so that it can provide stable and reliable support for the ventilation duct body.

[0019] The beneficial effects of the present application are as follows: when installing the ventilation duct main body, the end clamping strips arranged on its lower end face are located outside the two outer support plates. When the ventilation duct main body is lowered, its gravity will squeeze the side support plates to rotate and finally be in a horizontal position, so that the ends of the side support plates on both sides just rest against the end clamping strips on both sides respectively. At this time, the ventilation duct main body cannot slide longitudinally. Subsequently, the upper fixing plate is installed so that the grooves of the limit strips are clamped on both sides of the ventilation duct main body. While clamping the ventilation duct main body, the ventilation duct main body is also prevented from sliding laterally. At this point, the installation of the ventilation duct main body is completed. This installation device can play an auxiliary positioning role while ensuring the firmness of the installation, and can significantly improve the installation efficiency.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Reference Figure 1-3The air duct installation device includes a support and hanger 2 and a ventilation duct body 1 erected therein, the lower end surface of the ventilation duct body 1 is welded with an end clamping strip 3, the support and hanger 2 includes a main support plate 21, and the two ends of the upper end surface of the main support plate 21 are fixedly provided with a hanger 22, and the two side surfaces of the main support plate 21 are fixedly provided with a hinge seat 23, and the hinge seat 23 is rotatably provided with a side support plate 24 through a rotating connecting shaft 241. The end of the rotating connecting shaft 241 extends out of the hinge seat 23 and is sleeved with a torsion spring 25. An upper fixed plate 26 is slidably provided on the upper part of the hanger 22, and lateral limit strips 27 are fixedly provided on both sides of the lower end surface of the upper fixed plate 26. The upper part of the hanger 22 is located on the upper part of the upper fixed plate 26. The square thread is connected with a fastening nut 28. When the ventilation duct main body 1 is lowered, its gravity will squeeze the side support plate 24 to rotate and finally be in a horizontal position, so that the ends of the side support plates 24 on both sides just rest against the end clamping strips 3 on both sides respectively. At this time, the ventilation duct main body 1 cannot slide longitudinally. Subsequently, the upper fixing plate 26 is installed so that the limiting strip groove 271 is clamped on both sides of the ventilation duct main body 1. While clamping the ventilation duct main body 1, it also prevents the ventilation duct main body 1 from sliding horizontally. At this point, the installation of the ventilation duct main body 1 is completed. This installation device does not require welding and can ensure the firmness of the installation, which can significantly improve the installation efficiency.

[0029] Reference Figure 2 One end of the torsion spring 25 is fixedly connected to the side of the side support plate 24, and the other end of the torsion spring 25 is fixedly connected to the end of the rotating connecting shaft 241. By adopting the above technical solution, the side support plate 24 can be in a tilted state when it is not squeezed by the ventilation duct main body 1, so that the width of the overall structure is reduced to a certain extent, and the space occupied by the overall installation structure can be reduced to a certain extent. At the same time, it is also convenient for the placement of the ventilation duct main body 1, so that there is no need for more detailed positioning to ensure that the side support plates 24 on both sides are located in the two end clamping strips 3.

[0030] Reference Figure 4 The lower side of the end of the side support plate 24 is chamfered to form a full-length support plate groove 242. By adopting the above technical solution, it is possible to prevent the original sharp corner of the side support plate 24 from getting stuck when contacting the end clamping strip 3 and hindering the rotation of the side support plate 24.

[0031] Reference Figure 5 A card interface 261 that matches the cross-sectional size of the suspension rod 22 is opened on the side of one end of the upper fixing plate 26, and a reverse card interface 261 is opened on the other end of the upper fixing plate 26, which can facilitate the post-installation of the upper fixing plate 26 without having to put it on the suspension rod 22 in advance, thereby facilitating the installation work.

[0032] Reference Figure 6The inner side of the bottom of the lateral limit strip 27 is chamfered to form a full-length limit strip groove 271. By adopting the above technical solution, the limit strip groove 271 can play a guiding role. When installing the fixing plate 26, the lateral limit strip 27 can be guided by the limit strip groove 271 to make the lateral limit strip 27 stuck on both sides of the ventilation duct body 1, thereby improving the installation efficiency and fixing effect.

[0033] Reference Figure 4 The end clip strip 3 includes a clip strip body 31, and the inner side of the bottom of the clip strip body 31 is chamfered to form a full-length clip strip groove 311, and the inner side of the clip strip body 31 is fixed with a rubber fixing layer 32. By adopting the above technical solution, the clip strip groove 311 can guide the side support plate 24, making it convenient for the side support plate 24 to enter the inner space of the end clip strip 3, and the rubber fixing layer 32 can deform itself to closely contact the end of the side support plate 24 to play a supporting role, and at the same time does not hinder its normal rotation.

[0034] Reference Figure 2 A full-length reinforcing plate 211 is welded along the length direction at the middle part of the lower end surface of the main support plate 21. This structural form can enhance the overall bearing capacity of the main support plate 21, so that it can provide stable and reliable support for the ventilation duct body 1.

[0035] Working principle: first fix the entire support bracket 2 under the top plate of the structure through the suspension rod 22, lift the ventilation duct main body 1 and start installation. When installing the ventilation duct main body 1, make the end clamping strip 3 set on its lower end face be located outside the side support plates 24 on both sides of the main support plate 21. When the ventilation duct main body 1 is lowered, its gravity will squeeze the side support plates 24 to rotate and finally be in a horizontal position, so that the ends of the side support plates 24 on both sides just rest against the end clamping strips 3 on both sides respectively. At this time, the ventilation duct main body 1 cannot slide longitudinally. Subsequently, the upper fixing plate 26 is installed so that the limiting strip groove 271 is stuck on both sides of the ventilation duct main body 1. While cooperating with the main support plate 21 to clamp the ventilation duct main body 1, it also makes the ventilation duct main body 1 unable to slide laterally. At this point, the installation of the ventilation duct main body 1 is completed. This installation device can play an auxiliary positioning role while ensuring the firmness of the installation, and can significantly improve the installation efficiency.
