Description

Technical Field

[0001] The utility model relates to the field of temporary indoor ventilation equipment, in particular to an air exchange device used for temporary indoor ventilation. Background Art

[0002] After indoor decoration is completed or disinfection and other operations that affect indoor air quality are carried out, ventilation equipment is usually used temporarily to circulate and replace the indoor air with the outside air quickly and for a long time, so that the air in the house can quickly return to normal in a short time.

[0003] Most of the existing temporary ventilation equipment uses a high-power fan placed in front of the window to transport indoor air outwards, and opens the air intake window at another location to complete indoor ventilation. However, there is usually not enough space in front of the window in the indoor environment to place the fan. Therefore, the placement of the fan is usually reluctant or auxiliary equipment is used to set it up. However, the fan itself will generate large vibrations during operation, and a certain amount of wind will naturally be generated in the process of quickly discharging the air in the house. Both of these may cause the fan to fall due to instability or even fall out along the window, posing a major safety hazard. Utility Model Content

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the present utility model is to solve the problems existing in the existing technology: when the placement conditions of the fan near the indoor window are not met or are poor, the fan may fall over or even fall outward due to vibration during operation, posing a great safety hazard.

[0005] In order to solve the problems of the existing technology, the technical solution of the utility model is as follows: it includes two parallel rod sleeves, each end of the rod sleeve is connected with a movable rod, and the two ends of the rod sleeve are rotatably connected with a control sleeve, the inner wall of the control sleeve is threadedly connected to the movable rod, and the end of the movable rod away from the rod sleeve is provided with a mounting seat, and a slide groove is provided on the top of the mounting seat, and fixed tiles and movable tiles are arranged facing each other inside the slide groove, and soft rubber pads are provided on the opposite sides of the fixed tiles and the movable tiles, and adjusting bolts are provided on the parts of the fixed tiles and the movable tiles located inside the slide groove, and a center plate is provided on the opposite sides of the two parallel rod sleeves, and a fan assembly is provided inside the center plate.

[0006] Furthermore, two rectangular sliding grooves that are larger at the top and lower at the bottom are provided in parallel on the surface of the mounting seat, wherein one end of the sliding groove is closed and the other end is communicated with the outside.

[0007] Furthermore, a trapezoidal block adapted to the slide groove is provided at the bottom of the movable shoe, and a threaded hole is opened on the surface along the axial direction of the slide groove and is threadedly connected to the adjusting bolt through the threaded hole. The movable shoe can be moved along the slide groove by rotating the adjusting bolt, ensuring that the movement of the movable shoe requires manual operation.

[0008] Furthermore, the fixed tile is connected to the closed part of the closed end of the slide groove. Both the fixed tile and the movable tile are arc-shaped plate structures. The fixed tile itself is fixed in position, and an arc-shaped cavity is left between the fixed tile and the movable tile to adapt to the deformable soft rubber pad.

[0009] Furthermore, the adjusting bolt passes through the trapezoidal block at the bottom of the movable shoe and is rotatably connected to the closed end of the slide groove.

[0010] Furthermore, the soft rubber pad is a semicircular rubber block with a plurality of vertically distributed friction lines on the surface, which increases the friction between the soft rubber pad and the contact surface and increases the contact area through deformation.

[0011] Compared with the prior art, the advantages of the present invention are as follows:

[0012] The utility model makes both ends of the rod sleeve retractable by inserting a movable rod into the rod sleeve. Then, by adjusting the length of the movable rod, it can adapt to window frames of different sizes and make the window frame be located between the fixed tile and the movable tile. The operator can make the movable tile close to the fixed bolt by turning the adjusting bolt. During this process, the soft rubber pad is deformed so that the window frame is clamped between the fixed tile and the movable tile. When the position of the rod sleeve is fixed, the fan assembly between the rod sleeves is also restricted to a fixed position. The fan assembly is fixed inside the window frame by the overall structure and there is no need for sufficient placement space indoors. When the fan assembly is working, the vibration is transmitted to the rod sleeve through the center plate and when the movable rod enters the fixed tile and movable tile position, the vibration is absorbed by the soft rubber pad where the fixed tile and movable tile contact the window frame, thereby preventing the vibration from affecting the structure of the window frame itself.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] like Figure 1-3 As shown, a ventilation device for temporary indoor ventilation includes two parallel rod sleeves 1, with movable rods 2 inserted at both ends of the rod sleeves 1, and control sleeves 3 rotatably connected at both ends of the rod sleeves 1. The inner wall of the control sleeve 3 is threadedly connected to the movable rod 2, and a mounting seat 4 is provided at the end of the movable rod 2 away from the rod sleeve 1. A slide groove 5 is provided on the top of the mounting seat 4. Two rectangular slide grooves 5 are parallel to the surface of the mounting seat 4, one end of which is larger than the other, and the other end is connected to the outside.

[0019] A fixed tile 6 and a movable tile 7 are arranged facing each other inside the chute 5. A soft rubber pad 8 is arranged on the facing side of the fixed tile 6 and the movable tile 7. The soft rubber pad 8 is a semicircular rubber block with a plurality of vertically distributed friction lines on the surface, which increases the friction between the soft rubber pad 8 and the contact surface and increases the contact area by deformation. The fixed tile 6 is connected to the closed part of the closed end of the chute 5. The fixed tile 6 and the movable tile 7 are both arc-shaped plate structures. The fixed tile 6 itself is fixed in position, and an arc-shaped cavity is left between the fixed tile 6 and the movable tile 7 to adapt to the deformable soft rubber pad 8.

[0020] The fixed shoe 6 and the movable shoe 7 are located inside the slide 5 and are provided with an adjusting bolt 9. The adjusting bolt 9 passes through the trapezoidal block at the bottom of the movable shoe 7 and is rotatably connected to the closed end of the slide 5. A trapezoidal block adapted to the slide 5 is provided at the bottom of the movable shoe 7. A threaded hole is provided on the surface along the axial direction of the slide 5 and is threadedly connected to the adjusting bolt 9 through the threaded hole. The movable shoe 7 can be moved along the slide 5 by rotating the adjusting bolt 9 to ensure that the movement of the movable shoe 7 requires manual operation. A center plate 10 is provided on the opposite side of the two parallel rod sleeves 1, and a fan assembly 11 is provided inside the center plate 10.

[0021] Explanation of the working principle: First, during use, the operator rotates the control sleeve 3 to extend the movable rod 2 in the rod sleeve 1 outward until the extended diameter of the movable rod 2 is slightly smaller than the diameter of the window frame, and then places the fixed tile 6 and the movable tile 7 on the surface of the mounting seat 4 at the end of the movable rod 2 on one side of the center plate 10 on both sides of the window frame respectively, and then the operator rotates the adjusting bolt 9 to move the movable tile 7 toward the fixed tile 6. During the movement, the distance between the fixed tile 6 and the movable tile 7 decreases and the surface soft rubber pad 8 contacts the window frame. The operator continues to rotate the adjusting bolt 9 until the movable tile 7 can no longer move forward to complete the clamping of the window frame, and then the operator repeats the above operation on the other side of the center plate 10. When the center plate 10 is fixed by clamping the window frame with the fixed tile 6 and the movable tile 7 on the surface of the mounting seat 4 at the end of the movable rod 2, the fan assembly 11 is started. At this time, the fan assembly 11 is located between the window frames, does not require indoor space for placement, and will not be affected by its own vibration and fall.

[0022] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
