Description

Technical Field

[0001] The utility model relates to the technical field of ventilation windows, in particular to a ventilation window which is easy to seal and disassemble and is used in a laboratory ventilation system. Background Art

[0002] Ventilation windows are also called breathing windows and air exchange windows. According to the principles of atmospheric aerodynamics, they adopt mechanical exhaust and negative pressure air intake design. Without opening the windows, the indoor polluted air can be quickly discharged to the outside, and the outdoor fresh air can be purified and naturally balanced to enter the room, forming an indoor and outdoor air flow exchange to maintain the air quality of the indoor space. In the comparative case, the publication number is CN214943805U. The utility model relates to the field of laboratory ventilation technology, and in particular to a ventilation window that is easy to seal and disassemble for a laboratory ventilation system. In response to the problems raised in the background technology, the following scheme is proposed, including a window body, a placement groove is provided at one end of the window, and a filter frame is inserted in the placement groove. A mounting mechanism is provided on one side of the filter frame, and the mounting mechanism includes a fixed frame, a spring rod welded to the four corners of the outer wall of one end of the fixed frame, a connecting frame welded to the end of the spring rod away from the fixed frame, and a fastening screw screwed to the inner walls on both sides of the fixed frame. The utility model avoids directly installing the filter screen inside the window by screws by inserting the filter frame equipped with the dustproof net inside the window and fixing it through the installation mechanism. Since the first sealing frame and the second sealing frame are respectively provided on both sides of the filter frame for sealing connection, the filter frame can be easily disassembled and assembled while ensuring the overall dustproof filtering effect of the window.

[0003] However, in the implementation of relevant technologies, it was found that the above-mentioned laboratory ventilation system with ventilation windows that are easy to seal and disassemble has the following problems. In the comparative case, the window body, placement slot, filter frame and installation mechanism are used in combination to achieve the function of sealing connection. The structure is complex and takes up space. Most of the existing laboratory ventilation windows are integrated and cannot be disassembled and repaired separately, which reduces the convenience of disassembling the laboratory ventilation windows.

[0004] Therefore, it is necessary to redesign the ventilation windows to effectively prevent the problem that most laboratory ventilation windows are integrated and cannot be disassembled and repaired individually. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, the utility model provides a ventilation window for a laboratory ventilation system that is easy to seal and disassemble, comprising:

[0024] Window frame 1;

[0025] The inner cavity of the window frame 1 is movably connected to the frame 2, and the front and back ends of the inner wall of the frame 2 are movably connected to the connecting mechanism 3 through the bearing seat;

[0026] The connecting mechanism 3 includes a synchronous wheel 31, a louver 32, a belt 33, a turning handle 34 and a block 35. The front end and the back end of the inner wall of the frame 2 are movably connected to the synchronous wheel 31 through a bearing seat, the inner side of the synchronous wheel 31 is fixedly connected to the louver 32, the surface of the synchronous wheel 31 is fixedly sleeved with a belt 33, and the synchronous wheel 31 is connected by a transmission belt 33. The top and the bottom of the inner wall of the frame 2 are movably connected to the turning handle 34 through the bearing seat, the top of the turning handle 34 passes through the top of the frame 2 and is fixedly connected to the block 35, and the top of the block 35 is slidably connected to the top of the inner wall of the window frame 1.

[0027] refer to Figure 1 The top and bottom of the inner wall of the window frame 1 are both provided with T-slots 4 , which are used in conjunction with the clamping blocks 35 .

[0028] As a technical optimization solution of the present invention, the provision of the T-slot 4 can assist the block 35 in its work and simultaneously play a role of limiting, thereby avoiding the block 35 from getting stuck during movement.

[0029] refer to Figure 3 The surface of the synchronous wheel 31 is provided with an annular groove 5 , which is used in conjunction with the belt 33 .

[0030] As a technical optimization solution of the present invention, the provision of the annular groove 5 can assist the synchronous wheel 31 in working and at the same time play a limiting role, thereby preventing the belt 33 from being separated from the surface of the synchronous wheel 31.

[0031] refer to Figure 1 A sealing ring 6 is fixedly connected to the surface of the frame 2, and the sealing ring 6 is used in conjunction with the frame 2.

[0032] As a technical optimization solution of the present invention, the provision of the sealing ring 6 can assist the frame 2 in working, thereby avoiding the phenomenon of air leakage caused by a gap between the window frame 1 and the frame 2.

[0033] refer to Figure 2 The number of the louver fans 32 is four and they are evenly distributed. The louver fans 32 are used in conjunction with the synchronous wheel 31.

[0034] As a technical optimization solution of the present invention, the provision of the louver fan 32 can assist the frame 2 in working, thereby preventing the frame 2 from being unable to seal and block the wind as a whole.

[0035] refer to Figure 4 The surface of the turning handle 34 is provided with anti-skid patterns 7, and the anti-skid patterns 7 are used in conjunction with the turning handle 34.

[0036] As a technical optimization solution of the present invention, the provision of the anti-slip grooves 7 can assist the turning handle 34 in working, while increasing the friction resistance, thereby avoiding the turning handle 34 from slipping during rotation.

[0037] The working principle and usage process of the present invention are as follows: when in use, manually rotate the handle 34 clockwise by 90 degrees, and the rotation of the handle 34 by 90 degrees drives the block 35 to rotate and change the angle. The block 35 cooperates with the T-slot 4 to rotate and change the position so that it can slide out of the window frame 1, and then manually pull the frame 2 outward. The frame 2 moves and drives the block 35 to disengage along the T-slot 4, so that the window frame 1 and the frame 2 are completely disassembled for inspection and replacement. Similarly, the frame 2 is installed inside the window frame 1, and the louver 32 is rotated. The rotation of the louver 32 drives the synchronous wheel 31 and the belt 33 to rotate synchronously. The synchronous wheel 31 cooperates with the belt 33 to rotate so that multiple groups of louvers 32 rotate synchronously and change the angle. The rotation of the louver 32 changes the angle so that the gap between them is expanded to achieve the effect of ventilation.

[0038] To sum up: the laboratory ventilation system uses ventilation windows that are easy to seal and disassemble, and is used in conjunction with the window frame 1, frame 2, connecting mechanism 3, synchronous wheel 31, louver fan 32, belt 33, handle 34 and block 35 to solve the problem that most existing laboratory ventilation windows are integrated and cannot be disassembled and repaired separately.
