Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to a ventilation device for weak current engineering construction. Background Art

[0002] In current weak current engineering construction practices, the installation and maintenance of ventilation systems often become key factors hindering project progress and cost control. Traditional ventilation system designs often focus on functionality while neglecting ease of installation and maintenance. This results in complex installation procedures and high time costs for construction workers. Furthermore, when equipment requires maintenance or component replacement, the tedious disassembly process not only increases the workload but can also cause unnecessary damage to the equipment itself, further increasing maintenance costs.

[0003] Furthermore, as a crucial component of weak-current engineering, the structural stability and safety of ventilation systems are directly linked to the stable operation of the entire system and the safety of users' lives and property. However, traditional ventilation systems often suffer from numerous structural deficiencies, such as insufficiently secure connections and a lack of protective measures. These issues can become increasingly apparent over long-term use, posing a potential threat to the normal operation of the equipment. Therefore, we have developed a ventilation system for weak-current engineering construction. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a ventilation device for weak current engineering construction, which more accurately solves the problems raised in the above background technology.

[0005] The utility model is achieved through the following technical solutions:

[0006] The utility model proposes a ventilation device for weak current engineering construction, comprising a ventilation frame, a mounting frame, and an exhaust fan fixedly mounted inside the ventilation frame. A fixing column is fixedly mounted on the periphery of the ventilation frame, and the end of the fixing column is connected to a protective net frame. A disassembly structure 1 is connected between the ventilation frame and the protective net frame; a disassembly structure 2 is connected between the ventilation frame and the mounting frame.

A limited slot is opened on the side of the L-row connecting rod, and the second arc block is inserted into the inner wall of the limited slot to limit the movement of the L-row connecting rod;

[0008] The second disassembly and assembly structure includes a limit socket opened on the periphery of the installation frame and a strip groove 1 opened on the ventilation frame. A limit rod is inserted at the end of the strip groove 1, which is used to be inserted into the inner wall of the limit socket to limit the separation of the ventilation frame and the installation frame.

[0009] Furthermore, the disassembly and assembly structure 1 also includes a transverse fixing rod fixedly connected between the two end walls of the strip groove 2, the outer sleeve of the transverse fixing rod is provided with a spring 2, the outer sliding sleeve of the transverse fixing rod is connected with a sliding sleeve block, the sliding sleeve block is slidably connected to the inner wall of the strip groove 2, and the surface is fixedly connected to the arc block 2.

[0011] Furthermore, the end of the fixing column is fixedly connected to a plug-in column, a plug-in hole is opened on the surface of the protective net frame, and the plug-in column is inserted into the inner wall of the plug-in hole.

[0012] Furthermore, after the protective net frame is placed on the end of the fixed column, the end of the L-row connecting rod contacts the inner bottom wall of the strip groove 1, which is used to push the arc block 1 and the limiting rod to move, thereby achieving the purpose of inserting the limiting rod into the inner wall of the limiting hole.

[0013] Furthermore, one end of the second spring is fixedly connected to the end wall of the second strip groove, and the other end of the second spring is fixedly connected to one end surface of the sliding sleeve.

[0014] Beneficial effects of the utility model:

[0015] The utility model realizes quick installation and disassembly of the ventilation device of the present invention by designing the disassembly structure one and the disassembly structure two; the disassembly structure one utilizes the cooperation of the L-shaped connecting rod, the arc block two and the sliding sleeve block, and the automatic reset function provided by the spring two, so that the protective net frame can be easily installed on the ventilation frame and remain stable; similarly, the disassembly structure two realizes quick connection and separation between the ventilation frame and the installation frame by the cooperation of the limiting plug rod, the arc block one and the spring one; this design not only simplifies the installation process and reduces the construction difficulty, but also facilitates subsequent maintenance and replacement work, thereby improving work efficiency.

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0023] Example

[0024] like Figure 1-Figure 4 As shown, an embodiment of the present invention proposes a ventilation device for weak current engineering construction, the core components of which include a ventilation frame 1, a mounting frame 2 and an exhaust fan 3. In order to enhance the safety and maintainability of the ventilation device, a disassembly and assembly structure 1 and a disassembly and assembly structure 2 are specially designed. The disassembly and assembly structure 1 cooperates with the strip groove 2 12 and the sliding sleeve 15 on the ventilation frame 1 through the L-shaped connecting rod 6 to achieve rapid installation and disassembly of the protective net frame 5. Specifically, the limiting slot 17 opened on the side of the L-shaped connecting rod 6 cooperates with the arc block 2 16 fixed on the sliding sleeve 15. When the arc block 2 16 is inserted into the limiting slot 17, the movement of the L-shaped connecting rod 6 can be limited, thereby fixing the protective net frame 5.

[0025] Furthermore, a transverse fixing rod 13 and a second spring 14 are added. The transverse fixing rod 13 is fixed between the two ends of the second strip groove 12, providing a stable sliding track for the sliding sleeve 15. The second spring 14 is mounted around the periphery of the transverse fixing rod 13 and connected between the sliding sleeve 15 and the end wall of the second strip groove 12. This design allows the second arc block 16 to automatically reset when inserted into or out of the retaining slot 17, improving the convenience and reliability of the assembly and disassembly structure.

[0026] Furthermore, the design of the second disassembly mechanism is intended to enable quick connection and disconnection between the ventilation frame 1 and the mounting frame 2. The end of the stop rod 9 is equipped with an arc-shaped block 10, which slides within the strip groove 18. A spring 11 is also provided around the periphery of the stop rod 9. When the protective net frame 5 is placed on the end of the fixing column 4, the L-shaped connecting rod 6 pushes the arc-shaped block 10 and the stop rod 9, allowing the stop rod 9 to insert into the stop hole 7 on the mounting frame 2, thereby securing the ventilation frame 1 to the mounting frame 2.

[0027] Furthermore, to further strengthen the connection between the protective net frame 5 and the ventilation frame 1, plug-in posts 18 are added to the ends of the fixing posts 4, and insertion holes 19 that match the plug-in posts 18 are opened on the surface of the protective net frame 5. When the protective net frame 5 is placed on the ends of the fixing posts 4, the plug-in posts 18 automatically insert into the insertion holes 19, forming an additional fixing point. The matching design of the plug-in posts 18 and the insertion holes 19 further improves the installation stability of the protective net frame 5 and enhances the structural strength of the entire ventilation device.

[0028] Furthermore, when the protective net frame 5 is pushed to the end of the fixing column 4, the end of the L-shaped connecting rod 6 contacts the inner bottom wall of the strip groove 1 8, pushing the arc block 10 and the limiting rod 9 to slide along the strip groove 1 8. As the L-shaped connecting rod 6 continues to advance, the limiting rod 9 is automatically inserted into the limiting hole 7 under the action of the spring 1 11, thus achieving a fixed connection between the ventilation frame 1 and the installation frame 2.

[0029] Furthermore, one end of the second spring 14 is firmly fixed to the end wall of the second strip groove 12, and the other end is connected to the end surface of the sliding sleeve 15. This connection ensures that the second spring 14 can function stably during the disassembly and assembly process, providing a reliable power source for the automatic reset of the second arc block 16.
