Description

Technical Field

[0001] This application relates to the field of flow equalization membrane air supply technology, and more specifically, to a safe and environmentally friendly flow equalization membrane air supply device. Background Technology

[0002] An air supply ceiling is a purification device that can rationally distribute airflow within a clean room and effectively control the air cleanliness of the space to meet the requirements of various surgeries. It can be widely used in clean operating rooms, clean wards, clean animal rooms, and other projects in hospitals. The air supply ceiling should be used in conjunction with a flow equalization membrane to distribute the supplied air evenly.

[0003] Currently, flow equalization membranes are mainly installed at the air outlet. When replacement is needed, staff usually disassemble and replace the flow equalization membrane along with its outer mounting frame. However, when only the flow equalization membrane needs to be replaced and the mounting frame can still be used, this results in a waste of resources and is not very environmentally friendly.

[0004] To address the aforementioned issues, this application provides a safe and environmentally friendly flow equalization membrane air supply device. Utility Model Content

[0005] One objective of this application is to provide a safe and environmentally friendly flow equalization membrane air supply device, including an air outlet. A ceiling is provided on the outer side of the air outlet. A mounting frame is provided at the bottom of the ceiling and on the outer side of the lower end of the air outlet. An installation groove is opened on the upper side of the inner wall of the mounting frame. The lower end of the air outlet is inserted into the installation groove. A flow equalization membrane body is provided between the air outlet and the mounting frame. Slots are symmetrically opened on the outer side of the lower end of the air outlet. Two moving grooves are symmetrically opened on the outer side of the mounting frame. Fixed plates are symmetrically fixedly connected inside the moving grooves. A bidirectional screw rod is rotatably connected between the two fixed plates on one side of the mounting frame. A crossbar is fixedly connected between the two fixed plates on the other side of the mounting frame. Moving plates are symmetrically slidably connected inside the moving grooves. Limiting grooves are symmetrically opened on the outer side of the mounting frame. Insertion holes are opened on the inner bottom wall of the limiting grooves. Limiting plates are provided inside the limiting grooves. The two ends of the limiting plates are fixedly connected to the moving plates. Two adjacent moving plates are symmetrically threaded onto the outer side of the bidirectional screw rod. Insertion rods are provided inside the insertion holes.

[0006] Furthermore, the limiting plate is arranged in a "U" shape, with its two ends slidably connected to the inside of two moving slots, and two moving plates located on the other side of the mounting frame symmetrically slidingly sleeved on the outside of the crossbar.

[0007] Furthermore, one end of the insertion rod extends into the interior of the slot, and the other end of the insertion rod is fixedly connected to the inner surface of the limiting plate.

[0008] Furthermore, both the fixed plate and the movable plate are arranged in a "U" shape, and the limiting plate is arranged inside the fixed plate and the movable plate, and the limiting plate is slidably connected to the inner wall of the movable groove.

[0009] Furthermore, the right end of the bidirectional lead screw extends to the surface of the fixed plate and is fixedly connected to a rotating handle. A limit hole is provided on the rotating handle, and a positioning bolt is inserted into the limit hole. A threaded groove is provided on the surface of the fixed plate near the right end of the bidirectional lead screw, and the positioning bolt is threaded into the inside of the threaded groove.

[0010] Furthermore, a second rubber pad is provided at the bottom of the ceiling and on the outside of the air outlet, and a first rubber pad is provided on the bottom side of the air outlet and the inner bottom wall of the mounting groove.

[0011] The beneficial effects of this application are:

[0012] 1. When it is necessary to disassemble and replace the flow equalization membrane body, tighten the positioning bolts to move them out of the threaded groove, thereby releasing the limitation on the rotating handle; then tighten the rotating handle to drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the two adjacent moving plates to move towards each other, thereby driving the two limiting plates to move towards each other, and then driving the insertion rod to move out of the slot, thereby releasing the limitation on the mounting frame. Then, the mounting frame is moved downwards, and the flow equalization membrane body inside the mounting frame can be disassembled. The flow equalization membrane body can then be removed and replaced directly, avoiding the waste of resources caused by replacing the flow equalization membrane body together with the frame.

[0013] 2. When the insert rod is inserted into the slot, the limiting hole on the rotating handle corresponds to the threaded groove. At this time, the positioning bolt inside the limiting hole is screwed into the threaded groove, thereby fixing the rotating handle and further improving the stability of the connection between the mounting frame and the air outlet.

[0026] Example:

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 This application discloses a safe and environmentally friendly flow equalization membrane air supply device, including an air outlet 2. A ceiling 1 is provided on the outer side of the air outlet 2. A mounting frame 3 is provided at the bottom of the ceiling 1 and on the outer side of the lower end of the air outlet 2. An antistatic film layer is provided on the outer side of the mounting frame 3, giving the mounting frame 3 an antistatic function and improving safety. A mounting groove 17 is opened on the upper side of the inner wall of the mounting frame 3. The lower end of the air outlet 2 is inserted into the mounting groove 17. A flow equalization membrane body 4 is provided between the air outlet 2 and the mounting frame 3. Slots 2 are symmetrically opened on the outer side of the lower end of the air outlet 2. 1. Two symmetrical movable slots 6 are opened on the outer side of the mounting frame 3. Fixing plates 8 are symmetrically fixedly connected inside the movable slots 6. A bidirectional screw rod 13 is rotatably connected between the two fixing plates 8 on one side of the mounting frame 3. When the flow equalization membrane body 4 needs to be installed, the flow equalization membrane body 4 is placed inside the mounting slot 17. Then, the mounting frame 3 is fitted onto the lower outer side of the air outlet 2 and located at the bottom of the ceiling 1. The bidirectional screw rod 13 is then turned to rotate the insertion rod 11 into the slot 21, thus completing the fixation of the mounting frame 3. Two... A crossbar 10 is fixedly connected between the fixed plates 8. Moving plates 9 are symmetrically slidably connected inside the moving grooves 6. Limiting grooves 31 are symmetrically opened on the outer side of the mounting frame 3. The two ends of the limiting grooves 31 are respectively connected to the two moving grooves 6. Insertion holes 12 are opened on the inner bottom wall of the limiting grooves 31. Limiting plates 5 are installed inside the limiting grooves 31. The two ends of the limiting plates 5 are fixedly connected to the moving plates 9. The two moving plates 9 near the front side of the mounting frame 3 are symmetrically threaded onto the outer side of the bidirectional screw 13. Insertion rods 11 are installed inside the insertion holes 12. When it is necessary to disassemble the flow equalization membrane body 4... When replacing, unscrew the positioning bolt 15 to release the limit on the rotating handle 14, and then unscrew the rotating handle 14 to drive the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 causes the two adjacent moving plates 9 to move towards each other, thereby driving the two limiting plates 5 to move towards each other, and then driving the insertion rod 11 to move, so that the insertion rod 11 moves out of the slot 21, thereby releasing the limit fixation on the mounting frame 3, and then driving the mounting frame 3 to move downward, so that the flow equalization membrane body 4 inside the mounting frame 3 can be disassembled, and then the flow equalization membrane body 4 can be directly removed and replaced separately.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The limiting plate 5 is arranged in a "U" shape. The two ends of the limiting plate 5 are slidably connected to the inside of the two moving slots 6 respectively. The two moving plates 9 located on the other side of the mounting frame 3 are symmetrically slidably sleeved on the outside of the crossbar 10. One end of the insertion rod 11 extends into the inside of the slot 21, and the other end of the insertion rod 11 is fixedly connected to the inner surface of the limiting plate 5. The fixed plate 8 and the moving plate 9 are both arranged in a "U" shape. The limiting plate 5 is located inside the fixed plate 8 and the moving plate 9. The limiting plate 5 is slidably connected to the inner wall of the moving slot 6.

[0029] Please see Figure 2 , Figure 3 and Figure 4 The right end of the bidirectional lead screw 13 extends to the surface of the fixed plate 8 and is fixedly connected to a rotating handle 14. A limit hole is provided on the rotating handle 14, and a positioning bolt 15 is inserted into the limit hole. A threaded groove 16 is provided on the surface of the fixed plate 8 near the right end of the bidirectional lead screw 13, and the positioning bolt 15 is threaded into the threaded groove 16. When the insert rod 11 is inserted into the slot 21, the limit hole on the rotating handle 14 corresponds to the threaded groove 16. At this time, the positioning bolt 15 inside the limit hole is screwed into the threaded groove 16, thereby fixing the rotating handle 14 and further improving the stability of the connection between the mounting frame 3 and the air outlet 2.

[0030] A second rubber pad 7 is provided at the bottom of the ceiling 1 and outside the air outlet 2. A first rubber pad 41 is provided on the bottom side of the air outlet 2 and the inner bottom wall of the mounting groove 17. The first rubber pad 41 on the upper side of the flow equalization membrane body 4 is located between the air outlet 2 and the flow equalization membrane body 4, which can fill the gap between the two, prevent airflow from leaking from the gap, and ensure that the incoming air can be evenly treated through the flow equalization membrane body 4, thereby improving the flow equalization effect and air supply efficiency. The first rubber pad 41 on the lower side of the flow equalization membrane body 4 is located between the inner bottom wall of the mounting groove 17 and the flow equalization membrane body 4, which can prevent air from escaping from the gap and make the airflow flow according to the design path.

[0031] During the air supply process, the airflow will generate a certain impact force and vibration on the flow equalization membrane body 4. The rubber pad has good elasticity, which can buffer the impact force of the airflow on the flow equalization membrane body 4, reduce the wear and fatigue caused by vibration, extend the service life of the flow equalization membrane body 4, and also reduce the noise generated during operation. The elastic compression of the first rubber pad 41 and the second rubber pad 7 can firmly fix the flow equalization membrane body 4, prevent the flow equalization membrane body 4 from being displaced or shaking under the action of airflow, ensure its stability during operation, and enable the flow equalization membrane body 4 to always be in the correct position to perform the flow equalization function.

[0032] The implementation principle of this application embodiment is as follows: when it is necessary to disassemble and replace the flow equalization membrane body 4, the positioning bolt 15 is screwed on so that the positioning bolt 15 is moved out from the inside of the threaded groove 16, thereby releasing the limitation on the rotating handle 14.

[0033] Then, turn the handle 14 to drive the bidirectional lead screw 13 to rotate. The rotation of the bidirectional lead screw 13 causes the two adjacent moving plates 9 to move towards each other, thereby driving the two limiting plates 5 to move towards each other, and then driving the insertion rod 11 to move, so that the insertion rod 11 moves out of the slot 21, thereby releasing the limiting fixation on the mounting frame 3. Then, the mounting frame 3 is moved downward, so that the flow equalization membrane body 4 inside the mounting frame 3 can be disassembled. Then, the flow equalization membrane body 4 can be directly removed and replaced separately, avoiding the waste of resources caused by replacing the flow equalization membrane body 4 together with the frame.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
