Description

Technical Field

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

[0002] The air duct is a piping system used for air transportation and distribution. There are two types: composite air duct and inorganic air duct. Composite air duct can be classified according to cross-sectional shape and material. The production of stainless steel air duct is to apply sealant (such as neutral glass glue) on the bite seams, rivet seams, flange corners and other gaps. 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. The air duct is widely used in construction projects, and the connecting and fixing structure is an indispensable structure during the splicing and installation of the air duct. However, the air duct in the prior art is prone to duct deviation during installation and fixation, resulting in unsatisfactory duct fixing effect.

[0003] Therefore, it is necessary to provide a new air duct installation and fixing device to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an air duct installation and fixing device.

[0005] The air duct installation and fixing device provided by the utility model comprises a base frame, both sides of the base frame are provided with installation cavities, and a rotatably connected lead screw is installed in each of the installation cavities, and the opposite ends of the two lead screws extend out of the two ends of the base frame respectively and are fixedly installed with a rotating knob;

[0006] Each of the lead screws is provided with a side plate, and each of the side plates is provided with a T-shaped elastic airbag, and a top pressure plate for pressing the T-shaped elastic airbag is provided between the two side plates;

[0007] A plurality of vertically arranged suspension rods are fixedly mounted on the top pressure plate, and a mounting plate is fixedly mounted on the suspension rods.

[0008] Preferably, a sliding block is fixedly installed at the bottom of the side plate, and the sliding block is sleeved on the lead screw and threadedly connected to the lead screw, and limit blocks are fixedly installed on both side walls of the sliding block, and the limit blocks on both sides of the sliding block are respectively inserted into side sliding grooves opened on both side walls of the installation cavity and are slidably connected to the side sliding grooves.

[0009] Preferably, a T-shaped cavity is opened on the side plate, and the T-shaped cavity openings on the two side plates are arranged opposite to each other, and the bottom of the T-shaped elastic airbag is fixedly mounted on the bottom of the T-shaped cavity opened on the side plate.

[0010] Preferably, a rear slide groove is provided on the rear end surface of the side plate, and a fastening screw arranged parallel to the rear slide groove is fixed on the back side of the side plate.

[0011] Preferably, T-shaped plates are fixedly mounted on both ends of the top pressure plate, and extension plates are fixedly mounted on the backs of the two T-shaped plates, and through holes are formed on the extension plates.

[0012] Preferably, the T-shaped plates on both sides of the top pressure plate are respectively pressed into the T-shaped cavities of the side plates on both sides, and the extended plates at the ends of the T-shaped plates pass through the rear slide groove and are sleeved on the fastening screws through the opened through holes.

[0013] Preferably, a fastening nut for fastening the epitaxial plate is sleeved on the fastening screw.

[0014] Compared with the related art, the air duct installation and fixing device provided by the utility model has the following beneficial effects:

[0015] After the fastening nut is sleeved onto the fastening screw rod, the fastening nut is rotated downward to tighten the fastening nut. As the two ends of the top pressure plate are pushed downward, the T-shaped plates on both sides of the top pressure plate press down the T-shaped elastic airbags, and the T-shaped elastic airbags expand after being squeezed, so that the T-shaped elastic airbags expand outward toward the opening of the T-shaped cavity. The expanded T-shaped elastic airbags quickly fill the gap between the side plates and the air duct, thereby greatly improving the stability of the side plates clamping the air duct. Since the expanded T-shaped elastic airbags are elastic structures, the amplitude of the air duct caused by the airflow conveyed by the air duct is reduced in terms of structural form.

[0016] The utility model rotates the knob at the end of the lead screw, and because the sliding block at the bottom of the side plate is restricted by the limit block, the side plate can be driven to slide along the lead screw after the knob is rotated. Therefore, when the air duct is placed on the base frame, the two side plates can clamp and limit the air duct by rotating the knobs on both sides. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 4 An embodiment of the utility model provides an air duct installation and fixing device, which includes: a base frame 1, a side plate 2, a T-shaped elastic airbag 3 and a top pressure plate 4.

[0025] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 , both sides of the base frame 1 are provided with mounting cavities 1a, and a rotatably connected lead screw 11 is installed in each of the mounting cavities 1a, and the opposite ends of the two lead screws 11 extend out of the two ends of the base frame 1 respectively and are fixedly installed with a knob 12, and each of the lead screws 11 is installed with a side plate 2, specifically,

[0026] A sliding block 21 is fixedly installed at the bottom of the side plate 2, and the sliding block 21 is sleeved on the lead screw 11 and threadedly connected to the lead screw 11. Limit blocks 211 are fixedly installed on both side walls of the sliding block 21, and the limit blocks 211 on both sides of the sliding block 21 are respectively inserted into the side sliding grooves 1b opened on the two side walls of the installation cavity 1a and are slidably connected to the side sliding grooves 1b.

[0027] It should be noted that: by turning the knob 12 at the end of the lead screw 11, and because the sliding block 21 at the bottom of the side plate 2 is limited by the limit block 211, the side plate 2 can be driven to slide along the lead screw 11 after the knob 12 is turned, so that when the air duct is placed on the base frame 1, the knobs 12 on both sides can be turned to allow the two side plates 2 to clamp and limit the air duct;

[0028] Since the two side panels 2 are independent of each other, the air duct at the fixed position can be adjusted left and right according to the arrangement of the air duct, so that the air duct can be adjusted more flexibly.

[0029] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 , a T-shaped elastic airbag 3 is installed on each of the side panels 2, specifically, a T-shaped cavity 2a is opened on the side panel 2, and the openings of the T-shaped cavities 2a on the two side panels 2 are arranged opposite to each other, the bottom of the T-shaped elastic airbag 3 is fixedly installed on the bottom of the T-shaped cavity 2a opened on the side panel 2, and a rear slide groove 2b is opened on the rear end surface of the side panel 2, and a fastening screw 22 arranged parallel to the rear slide groove 2b is fixed on the back of the side panel 2;

[0030] A top pressure plate 4 for pressing the T-shaped elastic airbag 3 is arranged between the two side plates 2, and a T-shaped plate 41 is fixedly installed at both ends of the top pressure plate 4, and an extension plate 42 is fixedly installed on the back of the two T-shaped plates 41, and a through hole is opened on the extension plate 42, and the T-shaped plates 41 on both sides of the top pressure plate 4 are respectively pressed into the T-shaped cavity 2a of the two side plates 2, and the extension plate 42 at the end of the T-shaped plate 41 passes through the rear slide groove 2b and is sleeved on the fastening screw 22 through the opened through hole, and the fastening screw 22 is sleeved with a fastening nut 5 for fastening the extension plate 42;

[0031] It should be noted that: after the two side plates 2 clamp the air duct to a limited position, the T-shaped plates 41 on both sides of the top pressure plate 4 are pressed into the T-shaped cavities 2a of the side plates 2 on both sides, and the extended plates 42 at the ends of the T-shaped plates 41 pass through the rear slide groove 2b and are sleeved on the fastening screws 22 through the opened through holes. Subsequently, the fastening nuts 5 are sleeved on the fastening screws 22 and then rotated downward to tighten the fastening nuts 5. Since the two ends of the top pressure plate 4 are subjected to a downward pushing force, the T-shaped plates 41 on both sides of the top pressure plate 4 press down the T-shaped elastic airbags 3, and the T-shaped elastic airbags 3 expand after being squeezed, so that the T-shaped elastic airbags 3 expand outward toward the opening of the T-shaped cavity 2a, and the expanded T-shaped elastic airbags 3 quickly fill the gap between the side plates 2 and the air duct, thereby greatly improving the stability of the side plates 2 clamping the air duct, and since the expanded T-shaped elastic airbags 3 are an elastic structure, the amplitude of the air duct caused by the air flow conveyed by the air duct is reduced in structural form.

[0032] In the embodiments of the present invention, please refer to Figure 1 A plurality of vertically arranged suspension rods 6 are fixedly mounted on the top pressure plate 4, and a mounting plate 61 is fixedly mounted on the suspension rod 6. The mounting plate 61 can be fixed to the top wall of the house by screws.

[0033] The working principle of the air duct installation and fixing device provided by the utility model is as follows:

[0034] The knob 12 at the end of the lead screw 11 is turned, and since the sliding block 21 at the bottom of the side plate 2 is limited by the limit block 211, the side plate 2 can be driven to slide along the lead screw 11 after the knob 12 is turned. When the air duct is placed on the base frame 1, the knobs 12 on both sides can be turned to clamp the air duct to limit the position of the two side plates 2. Since the two side plates 2 are independent of each other, the air duct at the fixed position can be adjusted left and right according to the air duct layout line, so that the air duct can be adjusted more flexibly.

[0035] After the two side plates 2 clamp the air duct to a limited position, the T-shaped plates 41 on both sides of the top pressure plate 4 are pressed into the T-shaped cavities 2a of the two side plates 2 respectively, and the extended plates 42 at the ends of the T-shaped plates 41 pass through the rear slide groove 2b and are sleeved on the fastening screws 22 through the opened through holes. Subsequently, the fastening nuts 5 are sleeved on the fastening screws 22 and then rotated downward to tighten the fastening nuts 5. Since the two ends of the top pressure plate 4 are subjected to a downward pushing force, the T-shaped plates 41 on both sides of the top pressure plate 4 press down the T-shaped elastic airbags 3, and the T-shaped elastic airbags 3 expand after being squeezed, so that the T-shaped elastic airbags 3 expand outward toward the opening of the T-shaped cavity 2a, and the expanded T-shaped elastic airbags 3 quickly fill the gap between the side plates 2 and the air duct, thereby greatly improving the stability of the side plates 2 clamping the air duct, and since the expanded T-shaped elastic airbags 3 are an elastic structure, the amplitude of the air duct caused by the air flow conveyed by the air duct is reduced in structural form.

[0036] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
