Description

Technical Field

[0001] This utility model relates to the technical field of ventilation ducts, specifically a ventilation duct structure that is easy to assemble and disassemble. Background Technology

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases.

[0003] For example, a fire ventilation duct structure with authorization announcement number "CN216557505U" solves the problem that replacing the filter screen in existing fire ventilation duct structures is troublesome and requires a lot of labor and time. The above-mentioned structure uses the driving action of a drive motor to drive the rotating shaft to rotate. With the meshing action of the first gear and the second gear, the winding roller can rotate intermittently, thereby realizing the intermittent winding action of the winding roller on the filter screen. Considering that the existing fire ventilation duct structure uses a hanger to be directly installed on the fire ventilation duct and the ceiling, the operator needs to stand on a height to repeatedly operate the distance between the hanger, nut and hanger rod, which makes disassembly and assembly inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing fire ventilation duct structures require operators to repeatedly stand on heights to operate the distance between hangers, nuts and rods, resulting in inconvenience in disassembly and assembly. Therefore, this utility model proposes a ventilation duct structure that is easy to disassemble and assemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation duct structure that is easy to assemble and disassemble, comprising a ventilation duct and a fixing hole. The inner wall of the side end of the ventilation duct is machined with a fixing hole. The ventilation duct is fixedly connected to a collection box by bolts. The inner wall of the collection box is fixedly connected to a brush. The lower end of the brush is fixedly connected to a rubber strip. The outer wall of the ventilation duct is connected to an assembly and disassembly mechanism.

[0006] Preferably, the disassembly and assembly mechanism includes a square block, the outer wall of which is fixedly connected to the ventilation duct, the outer wall of which is inserted into the connecting frame, the outer wall of the connecting frame is fixedly connected to the hanger, and the outer wall of the hanger is inserted into the fixing member.

[0007] Preferably, the inner wall of the hanger abuts against the pin, the outer wall of the pin abuts against the fixing member, and the inner wall of the ventilation duct is connected to a cleaning mechanism.

[0008] Preferably, the cleaning mechanism includes a U-shaped strip, the outer wall of which is fixedly connected to the ventilation duct, the outer wall of which is slidably connected to the mounting frame, and a filter screen is installed inside the mounting frame.

[0009] Preferably, the inner wall of the fastener is machined with connecting holes.

[0010] Preferably, the mounting frame is fixedly connected to the ventilation duct by bolts.

[0011] The present invention proposes a convenient ventilation duct structure for easy assembly and disassembly. The beneficial effects are as follows: by pushing the connecting frame on the ventilation duct into the square block, the position of the connecting frame on the ventilation duct is restricted. The connection and disassembly between the pin and the hanger can be manually controlled. The ventilation duct can drive the connecting frame and the hanger to move left and right, so that the hanger can be hooked on the fixing part and the hanger can be connected or disassembled from the fixing part, thus realizing the quick assembly and disassembly of the ventilation duct and the ceiling.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-6In this embodiment, a ventilation duct structure that is easy to assemble and disassemble includes a ventilation duct 1 and a fixing hole 2. The fixing hole 2 is machined on the inner wall of the side end of the ventilation duct 1. The ventilation duct 1 is fixedly connected to the collection box 3 by bolts. The inner wall of the collection box 3 is fixedly connected to the brush 4. The lower end of the brush 4 is fixedly connected to the rubber strip 5. The outer wall of the ventilation duct 1 is connected to the disassembly and assembly mechanism 6.

[0022] The disassembly and assembly mechanism 6 includes a square block 601, which is inserted into the hanger 603 via a pin 7. The hanger 603 is fixed and separated from the fixing member 604, thereby realizing the disassembly and assembly of the ventilation duct 1 and the ceiling. The outer wall of the square block 601 is fixedly connected to the ventilation duct 1, the outer wall of the square block 601 is inserted into the connecting frame 602, the outer wall of the connecting frame 602 is fixedly connected to the hanger 603, and the outer wall of the hanger 603 is inserted into the fixing member 604.

[0023] The connecting frame 602 on the ventilation duct 1 is pushed into the square block 601, restricting the position of the connecting frame 602 on the ventilation duct 1. The connection and disconnection between the pin 7 and the hanger 603 are manually controlled. The ventilation duct 1 can drive the connecting frame 602 and the hanger 603 to move left and right, so that the hanger 603 can hook onto the fixing part 604. The hanger 603 is connected or disconnected from the fixing part 604, realizing the quick assembly and disassembly of the ventilation duct 1 and the ceiling.

[0024] The inner wall of the hanger 603 abuts against the pin 7, and the outer wall of the pin 7 abuts against the fastener 604. The inner wall of the ventilation duct 1 is connected to a cleaning mechanism 8. The mounting frame 802 and the filter screen 803 move downward in the ventilation duct 1, and the brush 4 on the collection box 3 cleans the surface of the filter screen 803, so that the dust on the surface of the filter screen 803 is cleaned. The cleaning mechanism 8 includes a U-shaped strip 801. The outer wall of the U-shaped strip 801 is fixedly connected to the ventilation duct 1, and the outer wall of the U-shaped strip 801 is slidably connected to the mounting frame 802. The mounting frame 802 is made of ABS resin with added flame retardant and UV-resistant properties. The filter screen 803 is installed inside the mounting frame 802. The filter screen 803 is made of nylon fiber synthetic resin. The inner wall of the fastener 604 is machined with a connecting hole 9. The mounting frame 802 is fixedly connected to the ventilation duct 1 by bolts.

[0025] Working principle:

[0026] First, external bolts are passed through the connecting holes 9 on the fixing member 604 to secure the fixing member 604 to the ceiling. Then, the connecting frame 602 on the ventilation duct 1 is pushed into the square block 601. The square groove machined on the surface of the connecting frame 602 and the square block 601 form an interlock, restricting the position of the connecting frame 602 on the ventilation duct 1. The ventilation duct 1 is lifted, causing the connecting frame 602 and the hanger 603 to move closer to the fixing member 604, so that the hanger 603 hooks onto the fixing member 604. At the same time, the pin 7 is inserted into the hanger 603, preventing the hanger 603 from detaching from the fixing member 604, thus achieving the installation between the ventilation duct 1 and the ceiling. When it is necessary to disassemble the ventilation duct 1, the pin 7 is manually pulled out to detach from the hanger 603, and the ventilation duct 1 is pushed to the left to detach the hanger 603 from the fixing member 604, achieving the effect of quick disassembly and assembly between the ventilation duct 1 and the ceiling.

[0027] When the filter screen 803 inside the ventilation duct 1 needs to be removed, loosen the bolts between the mounting frame 802 and the ventilation duct 1 to allow the mounting frame 802 and the filter screen 803 to move within the ventilation duct 1. Manually pull the mounting frame 802 downwards. The outer walls of the mounting frame 802 and the filter screen 803 will pass through the brush 4 on the collection box 3. The inner side of the brush 4 will rub against the mounting frame 802 and the filter screen 803, and the brush 4 on the collection box 3 will clean the surface of the filter screen 803, causing a large amount of dust on the surface of the filter screen 803 to fall into the collection box 3. At the same time, the mounting frame 802 and the filter screen 803 will also pass through the rubber strip 5 to prevent a large amount of dust from entering during the removal of the filter screen 803. The soil falls onto the dismantling personnel, ensuring their cleanliness. The new mounting frame 802 and filter screen 803 are then passed through the collection box 3 and rubber strip 5 from the bottom (the brush 4 and rubber strip 5 need to be cleaned before installation). The mounting frame 802 and filter screen 803 are pushed into the ventilation duct 1. The outer wall of the mounting frame 802 slides into the inner wall of the U-shaped strip 801, ensuring a seal between the mounting frame 802 and the U-shaped strip 801. The mounting frame 802 is then reinstalled and fixed to the ventilation duct 1 with bolts. Depending on the usage time, the bolts between the collection box 3 and the ventilation duct 1 can be loosened periodically to allow for cleaning of the dust inside the collection box 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
