Technical Field
[0001] This utility model belongs to the field of pipeline protection technology, and specifically relates to a protective device for laying air purification pipelines. Background Technology
[0002] Air purification ducts are the core carriers for airflow delivery in environments with stringent air quality requirements, such as cleanrooms, medical operating rooms, and electronic semiconductor workshops. These ducts must possess extremely high levels of sealing, internal wall cleanliness, and structural stability. Problems during installation, such as port deformation, damage to the outer coating, intrusion of foreign objects, or failure of interface seals, can lead to leakage of clean airflow and infiltration of unclean air. Therefore, implementing targeted protective devices throughout the entire process of air purification duct installation—from transportation and storage to processing, hoisting, and connection—to ensure the integrity of the duct body and critical components, is a crucial prerequisite for ensuring the compliant operation of the purification system.
[0003] Currently, during the installation of air purification ducts, most ducts are fixed using only simple metal clips, plastic cable ties, or ordinary brackets. This type of fixing method can only limit the position of the duct and cannot cover the air purification duct. There are many working devices on the construction site, and when the working devices are adjusting their positions, they are prone to colliding with the exposed air purification duct, causing damage.

[0008] Furthermore, the first sliding assembly includes a slider, which is slidably connected inside the fixed base. The fixed base has a groove for the slider to slide in. A first spring is fixedly connected to the top of the slider, and a first inclined block is fixedly connected to the side of the slider. The upper end of the first spring is fixedly connected inside the fixed base.
[0009] Furthermore, the second sliding component includes a second inclined block, a sliding plate is fixedly connected to the outer surface of the second inclined block, a second spring is fixedly connected to the side of the sliding plate, one end of the second spring is fixedly connected to the inside of the sliding seat, the second inclined block and the sliding plate are both slidably connected inside the sliding seat, and the sliding directions of the first inclined block and the second inclined block are perpendicular to each other.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-8 As shown, this utility model is a protective device for laying air purification ducts, including a fastening component 1. The fastening component 1 has a first sliding component 2 and a second sliding component 3 respectively disposed inside it. The fastening component 1 is divided into two parts, and the two parts of the fastening component 1 are engaged by the first sliding component 2 and the second sliding component 3. The outer surface of the fastening component 1 is provided with a docking component 4, which is used to dock and fix multiple sets of fastening components 1.
[0031] After fixing the disassembled fastening assembly 1 to the indoor ceiling, install the air purification duct inside the upper half of the fastening assembly 1. Then, fasten the lower half of the fastening assembly 1 to the upper half. During the fastening process, the second sliding component 3 inside the lower half of the fastening assembly 1 is squeezed by the upper half of the fastening assembly, causing the second sliding component 3 to retract into the lower half of the fastening assembly 1 until it passes the hook of the upper half of the fastening assembly 1 and resets, completing the connection of the fastening assembly 1. Multiple sets of fastening assemblies 1 are connected by the interlocking components 4. The fastening assembly 1 is connected and fixed by interlocking. When it is necessary to disassemble the fastening assembly 1, push the lower half of the fastening assembly 1 to continue moving upward until the second sliding assembly 3 passes the first sliding assembly 2. Then pull the lower half of the fastening assembly 1 and drive the first sliding assembly 2 downward through the second sliding assembly 3 until the first sliding assembly 2 moves to the bottom. Then the second sliding assembly 3 can pass the first sliding assembly 2 and fasten the hook of the upper half of the fastening assembly 1, so that the lower half of the fastening assembly 1 is separated from the upper half. At this time, the air purification pipe inside the fastening assembly 1 can be inspected.
[0032] The two parts of the fastening component 1 of this utility model are fixed by the second sliding component 3. The air purification pipe is located inside the fastening component 1. The fastening component 1 protects the air purification pipe from the outside. When the equipment at the construction site is moved, it cannot cross the fastening component 1 and collide with the air purification pipe, thus avoiding damage to the air purification pipe.
[0033] In one embodiment, the fastening assembly 1 includes a fixing seat 101, a sliding seat 102 slidably connected inside the fixing seat 101, a first bent plate 103 fixedly connected to the outer surface of the fixing seat 101, and a second bent plate 104 fixedly connected to the outer surface of the sliding seat 102. The second bent plate 104 is inserted into the first bent plate 103. The fixing seat 101 and the sliding seat 102 are used to protect the air purification duct.
[0034] After the mounting base 101 is installed on the indoor ceiling, the air purification duct is laid inside the mounting base 101. The sliding base 102 is fastened to the mounting base 101, and the sliding base 102 drives the second bent plate 104 to insert into the first bent plate 103 on the mounting base 101. At this time, the mounting base 101 and the sliding base 102 cover the air purification duct, which can protect the air purification duct. At the same time, the setting of the first bent plate 103 and the second bent plate 104 can extend the path of outside air carrying dust into the mounting base 101 and the sliding base 102, thereby reducing the amount of dust entering the mounting base 101 and the sliding base 102.
[0035] In one embodiment, the first sliding component 2 includes a slider 201, which is slidably connected to the inside of the fixed base 101. The fixed base 101 has a groove for sliding the slider 201. A first spring 202 is fixedly connected to the top of the slider 201, and a first inclined block 203 is fixedly connected to the side of the slider 201. The upper end of the first spring 202 is fixedly connected to the inside of the fixed base 101.
[0036] In one embodiment, the second sliding component 3 includes a second inclined block 301, a sliding plate 302 is fixedly connected to the outer surface of the second inclined block 301, a second spring 303 is fixedly connected to the side of the sliding plate 302, one end of the second spring 303 is fixedly connected to the inside of the sliding seat 102, the second inclined block 301 and the sliding plate 302 are both slidably connected to the inside of the sliding seat 102, and the sliding directions of the first inclined block 203 and the second inclined block 301 are perpendicular to each other.
[0037] During the process of fastening the sliding seat 102 inside the fixed seat 101, the sliding seat 102 drives the second inclined block 301 to move. The second inclined block 301 is squeezed by the fixed seat 101, which causes the second inclined block 301 to drive the sliding plate 302 to compress the second spring 303 until the second inclined block 301 passes the hook of the fixed seat 101. Then the second spring 303 pushes the second inclined block 301 to return to its original position. At this time, the sliding seat 102 is released, and the sliding seat 102 is locked inside the fixed seat 101 by the second inclined block 301. When it is necessary to separate the sliding seat 102 and the fixed seat 101, pushing the sliding seat 102 causes the second inclined block 301 to continue moving upward. The second inclined block 301 causes the first inclined block 203 and the slider 201 to slide upward. After the slider 201 moves to its limit position, the second inclined block 301 is squeezed by the first inclined block 203, causing the second inclined block 301 to compress the second spring 303 and retract into the sliding seat 102. Continuing to push the sliding seat 102 causes the second inclined block 301 to move past the first inclined block 203. At this time, the second spring 303 pushes the second inclined block 301 back to its original position, and then the sliding seat 102 is pulled again. 2. The second inclined block 301 moves downward. After the second inclined block 301 moves the first inclined block 203 and the slider 202 downward to the limit position, the bottom surface of the first inclined block 203 fits with the hook of the fixed seat 101. The slider 102 continues to be pulled to move. The second inclined block 301 inside the slider 102 is squeezed by the first inclined block 203, causing the second inclined block 301 to retract into the slider 102. At this time, the second inclined block 301 no longer limits the slider 102, and the slider 102 can be removed from the fixed seat 101 to facilitate the maintenance of the air purification pipe inside the fixed seat 101.
[0038] In one embodiment, the docking assembly 4 includes a first ear plate 401 and a second ear plate 402. The outer surface of the first ear plate 401 is fixedly connected with a fixing bolt 403, and the outer surface of the second ear plate 402 is provided with a connection hole 404. The first ear plate 401 and the second ear plate 402 are both fixedly connected to the side of the fixing base 101.
[0039] When the first ear plate 401 on the outer surface of one set of fixing base 101 is inserted into the second ear plate 402 on the outer surface of another set of fixing base 101, the fixing bolt 403 on the outer surface of the first ear plate 401 enters into the connecting hole 404 on the outer surface of the second ear plate 402, and the connection and fixing are completed by installing a nut on the outer surface of the fixing bolt 403.
[0040] In one embodiment, the fixing seat 101 is internally threaded with a connecting bolt 5, and the fixing seat 101 is fixedly connected with a clip 6 by the connecting bolt 5.
[0041] The clip 6 is a flexible clip. After the clip 6 is opened, the air purification pipe is placed into the clip 6. Releasing the clip 6 to reset it can limit the air purification pipe and allow the air purification pipe to be installed in the fixed seat 101.
[0042] In one embodiment, the fixing seat 101 described above has a positioning bolt 7 internally threadedly connected to it.
[0043] The positioning bolt 7 penetrates the fixing seat 101 and extends into the wall. The fixing seat 101 can be fixed to the indoor ceiling by the positioning bolt 7.
[0044] Through the above technical solution, 1. The two parts of the fastening component 1 are locked together by the second sliding component 3. The air purification pipe is located inside the fastening component 1, and the fastening component 1 protects the air purification pipe from the outside. When the equipment is moved at the construction site, it cannot cross the fastening component 1 and collide with the air purification pipe, thus avoiding damage to the air purification pipe; 2. When the second inclined block 301 is located between the hook of the fixing seat 101 and the first inclined block 203, the second inclined block 301 and the hook of the fixing seat 101 are in planar contact. At this time, the first... The two inclined blocks 301 prevent the sliding seat 102 from coming out of the fixed seat 101. They push the sliding seat 102 and the second inclined block 301 upward, so that the second inclined block 301 passes the first inclined block 203. Then, they pull the sliding seat 102 to move the second inclined block 301 and the first inclined block 203 downward until the second inclined block 301 passes the first inclined block 203 and the hook of the fixed seat 101. This releases the connection between the sliding seat 102 and the fixed seat 101, making it easier to separate the sliding seat 102 and the fixed seat 101, and providing convenience for subsequent maintenance.
