Description

Technical Field

[0001] This utility model belongs to the field of ventilation technology, and in particular relates to a ventilation damper opening and closing mechanism. Background Technology

[0002] According to the published patent CN205606814U, a rotary switch door and window ventilator includes a ventilator shell, a damper, a switch, and internal noise-reducing and heat-insulating foam. The feature is that the internal noise-reducing and heat-insulating foam wraps around the inner wall of the ventilator shell, except for the horizontally opposite air inlet and outlet, forming an O-shaped air duct area at the end face. The rotary switch is used to better adapt to the user's habit of using ventilators installed in a low position. However, it still has the following shortcomings.

[0003] During the use of the above-mentioned equipment, a large amount of air will pass through the inside of the casing during long-term use. During this period, the air will also carry a large amount of dust into the inside of the casing and accumulate there. It is difficult to directly clean the inside of the casing, and the cleaning efficiency is very low. Therefore, we propose a ventilation damper opening and closing mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation damper opening and closing mechanism. Through the quick-release mechanism and the opening and closing mechanism, the problem of a large amount of air passing through the inside of the outer shell during long-term use of the equipment, during which a large amount of dust carried by the air enters the inside of the outer shell and accumulates, making it difficult to directly clean the inside of the outer shell and resulting in very low cleaning efficiency is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a ventilation damper opening and closing mechanism, including a housing, an adjusting seat fixedly connected to the outer wall of the housing, and a quick-release mechanism provided on the top outer wall of the housing;

[0007] The quick-release mechanism includes a mounting base, the bottom outer wall of which is fixedly connected to the top outer wall of the outer casing. The inner wall of the mounting base has a mounting groove, and a protective mesh is slidably connected to the inner wall of the mounting groove. The outer wall of the mounting base is fixedly connected to the mounting groove, and a shaft seat is rotatably connected to the inner wall of the mounting groove. A rotating shaft is rotatably connected to the inner wall of the shaft seat, and a fixing frame is fixedly connected to the outer wall of the rotating shaft. Several connecting blocks are fixedly connected to the outer wall of the fixing frame, and each connecting block has a fixing groove on its inner wall. The inner wall of the adjusting base has several pin grooves, and a fixing pin is slidably connected to the inner wall of each pin groove. A push button is fixedly connected to the outer wall of each fixing pin.

[0008] Furthermore, a spring is fixedly connected to the outer wall of the fixing pin, and the outer wall of the spring is fixedly connected to the inner wall of the pin groove.

[0009] Furthermore, the inner wall of the outer casing is provided with an opening and closing mechanism, which includes a plurality of dampers. The outer walls of the dampers are rotatably connected to the inner wall of the outer casing, and the outer walls of the dampers are fixedly connected to the outer wall of the connecting rod.

[0010] Furthermore, a connecting block is rotatably connected to the outer wall of the connecting rod, and a sliding sleeve is fixedly connected to the outer wall of the connecting block.

[0011] Furthermore, a sliding rod is slidably connected to the inner wall of the sliding sleeve, and a displacement block is fixedly connected to the bottom outer wall of the sliding rod.

[0012] Furthermore, the inner wall of the displacement block is connected to a threaded rod, and the outer wall of the threaded rod is rotatably connected to the inner wall of the adjusting seat.

[0013] Furthermore, the threaded rod extends through the adjusting seat to the outer wall, and a knob is fixedly connected to the outer wall of the threaded rod.

[0014] Furthermore, the inner wall of the displacement block is slidably connected with several sliding rods, and the outer walls of the several sliding rods are fixedly connected to the inner wall of the adjusting seat.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a fixed frame that allows several push buttons to be squeezed inwards. Each push button causes a fixed pin to displace, disengaging from the fixed groove and compressing a spring. Once disengaged, the fixed pin no longer restricts the movement of the connecting block, allowing the fixed frame to be flipped towards the shaft seat. The protective net can then be lifted out of the mounting groove. After cleaning the inside of the casing, the protective net can be reinstalled. During this process, the fixed frame holds the protective net in place to prevent it from dislodging from the mounting groove. This design prevents large foreign objects from falling into the casing and affecting ventilation, while also allowing for quick and easy disassembly and replacement of the protective net, facilitating direct cleaning of the inside of the casing.

[0017] 2. This utility model, by setting a displacement block, allows for a larger gap between several dampers during ventilation, thus increasing the space available for airflow. To adjust the gap between several dampers, the knob can be turned counterclockwise. The knob will rotate the threaded rod, which in turn will move the displacement block. The displacement block will then move the sliding rod, which will move the sliding sleeve, which will then move the connecting block. The connecting block will then rotate several connecting rods, which in turn will rotate the dampers. This allows for the opening and closing of the dampers and the free adjustment of their angles to indirectly control the amount of airflow allowed, satisfying most ventilation requirements.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The quick-release mechanism 2 includes a mounting base 201, the bottom outer wall of which is fixedly connected to the top outer wall of the outer casing 1. An mounting groove 202 is formed on the inner wall of the mounting base 201, and a protective net 203 is slidably connected to the inner wall of the mounting groove 202. The mounting groove 202 mainly serves to limit the sliding movement of the protective net 203, allowing the protective net 203 to slide within the mounting groove 202 at a fixed angle. The mounting groove 202 is fixedly connected to the outer wall of the mounting base 201, and a bearing 204 is rotatably connected to the inner wall of the mounting groove 202. A rotating shaft 205 is rotatably connected to the inner wall of the bearing 204, and a fixing frame 206 is fixedly connected to the outer wall of the rotating shaft 205. The bearing 204 mainly serves to limit the rotation of the rotating shaft 205. The shaft 205 can only rotate in a fixed position within the shaft seat 204. Several connecting blocks 207 are fixedly connected to the outer wall of the fixed frame 206. The inner walls of the connecting blocks 207 are provided with fixing grooves 208. The inner wall of the adjusting seat 101 is provided with several pin grooves 209. The fixed frame 206 mainly serves to fix and limit the connecting blocks 207. The connecting blocks 207 can only be fixed in a fixed position on the fixed frame 206. The inner walls of the pin grooves 209 are slidably connected with fixing pins 210. The outer wall of the fixing pins 210 is fixedly connected with push buttons 211. The shape of the push buttons 211 is convenient for users to hold and push directly. When the push buttons 211 move, they will drive the fixing pins 210 to move as well.

[0031] A spring 212 is fixedly connected to the outer wall of the fixing pin 210. The outer wall of the spring 212 is fixedly connected to the inner wall of the pin groove 209. An opening and closing mechanism 3 is provided on the inner wall of the outer shell 1. The opening and closing mechanism 3 includes several dampers 301. The spring 212 mainly supports and limits the fixing pin 210. The fixing pin 210 will be supported in a fixed position by the spring 212 without external force. After the fixing pin 210 is displaced, it will be driven back to its original position by the spring 212. The outer walls of the several dampers 301 are rotatably connected to the inner wall of the outer shell 1. The outer walls of the several dampers 301 are all fixedly connected to the outer wall of the connecting rod 302. The outer shell 1 mainly limits the rotation of the several dampers 301. The several dampers 301 can only rotate in a fixed position inside the outer shell 1.

[0032] A connecting block 303 is rotatably connected to the outer wall of the connecting rod 302. A sliding sleeve 304 is fixedly connected to the outer wall of the connecting block 303. A sliding rod 305 is slidably connected to the inner wall of the sliding sleeve 304. A displacement block 306 is fixedly connected to the bottom outer wall of the sliding rod 305. The displacement block 306 mainly serves to fix and support the sliding rod 305. When the displacement block 306 moves, it will drive the sliding rod 305 to move as well. A threaded rod 307 is drivenly connected to the inner wall of the displacement block 306. The outer wall of the threaded rod 307 is rotatably connected to the inner wall of the adjusting seat 101. The threaded rod 307 passes through the adjusting seat 101 to the outer wall. The adjusting seat 101 mainly serves to limit the rotation of the threaded rod 307. The threaded rod 307 can only rotate in a fixed position within the adjusting seat 101. A knob 308 is fixedly connected to the outer wall of the threaded rod 307. Several sliding rods 309 are slidably connected to the inner wall of the displacement block 306. The outer walls of the sliding rods 309 are fixedly connected to the inner wall of the adjusting seat 101. The threaded rod 307 mainly serves to limit the rotation of the knob 308. The shape of the knob 308 makes it easy for the user to pinch and rotate it. When the knob 308 rotates, it will drive the threaded rod 307 to rotate as well.

[0033] One specific application of this embodiment is:

[0034] When the equipment is needed, after installation in a suitable position, air will flow through the gaps between several dampers 301 inside the outer casing 1. The protective net 203 prevents large foreign objects from falling into the outer casing 1. If the protective net 203 needs to be removed separately for cleaning the inside of the outer casing 1, several push buttons 211 can be squeezed inward. Each push button 211 will cause the fixing pin 210 to move, and the fixing pin 210 will disengage from the fixing groove 208 while squeezing the spring 212. After the fixing pin 210 disengages from the fixing groove 208, the movement of the connecting block 207 will no longer be restricted. The fixing frame 206 can then be flipped towards the shaft seat 204. The protective net 203 can then be lifted out of the mounting groove 202. After cleaning the inside of the outer casing 1, the protective net 203 can be reinstalled. During this process, the fixing frame 206 will press down on the protective net 203 to prevent it from... After detaching from the mounting slot 202, several fixing pins 210 will be inserted into the fixing slot 208 to indirectly fix the frame 206. When ventilation is performed, the larger the gap between the several dampers 301, the larger the space for airflow to pass through. If it is necessary to adjust the gap between the several dampers 301, the knob 308 can be turned counterclockwise. The knob 308 will drive the threaded rod 307 to rotate, the threaded rod 307 will drive the displacement block 306 to move, the displacement block 306 will drive the sliding rod 305 to move, the sliding rod 305 will drive the sliding sleeve 304 to move, the sliding sleeve 304 will drive the connecting block 303 to move, the connecting block 303 will drive several connecting rods 302 to rotate, and the several connecting rods 302 will drive the dampers 301 to rotate. During the rotation of the dampers 301, the gap for airflow to pass through will increase or decrease. When the several dampers 301 are rotated to the same horizontal line, the airflow will not be able to pass through the outer casing 1.
