[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1 The present invention provides an easy-to-use fume hood, comprising: a fume hood body 1 and a fixing structure 3. Several storage devices 6 are installed inside the fume hood body 1 by means of the fixing structure 3. A glass plate 5 is installed inside the fume hood body 1. Three ventilation rings 7 are installed inside the glass plate 5. Two cabinet doors 2 are installed inside the fume hood body 1. The fixing structure 3 is provided inside the fume hood body 1. A limiting structure 4 is provided on one side of the fume hood body 1.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 The fixing structure 3 includes a fixing plate 301, which is fixedly connected to the fume hood body 1. The inner wall of the fixing plate 301 has several limiting grooves 302. A connecting plate 303 is slidably connected to the inner wall of each limiting groove 302. A connecting plate 305 is fixedly connected to the lower surface of the connecting plate 303. A base plate 306 is fixedly connected to the side of the connecting plate 305 closest to the fixing plate 301. A connecting column 314 is fixedly connected to the lower surface of the base plate 306. The connecting column 314 is fixedly connected to the storage device 6. The inner wall of the connecting plate 303 has... The connecting groove 315 and the positioning groove 307 are interconnected. A fixing rod 311 is fixedly connected to the inner wall of the limiting groove 302. The fixing rod 311 is slidably connected to the connecting groove 315 and the positioning groove 307. A positioning plate 308 is slidably connected to the arc surface of the fixing rod 311. The positioning plate 308 is slidably connected to the positioning groove 307. A spring 312 is sleeved on the arc surface of the fixing rod 311. The two ends of the spring 312 are fixedly connected to the positioning plate 308 and the fixing rod 311, respectively. When personnel need to fix the storage device 6 inside the fume hood body 1, they can move the storage device 6 to slide the connecting plate 303 into the inner wall of the limiting groove 302 until the positioning plate 308 slides into the inner wall of the positioning groove 307. This allows for quick and easy fixing of the storage device 6, improving installation efficiency. The arc surface of the spring 312 is fitted with a bellows 313, with both ends of the bellows 313 fixedly connected to the fixing rod 311 and the positioning plate 308, respectively. The bellows 313 protects the spring 312 and effectively reduces the impact of environmental factors on the spring 312. Two guide blocks 304 are fixedly connected to the side of the connecting plate 303 away from the connecting plate 305. The guide blocks 304 guide the connecting plate 303, making it easy for personnel to slide the connecting plate 303 into the inner wall of the limiting groove 302. Two pull rings 309 with circular cross-sections are fixedly connected to the upper surface of the positioning plate 308. The pull ring 309 facilitates the movement of the positioning plate 308, improving operational convenience. The arc-shaped surface of the pull ring 309 is fitted with an anti-slip sleeve 310, which has a hollow circular cross-section. The anti-slip sleeve 310 increases the friction between the user's hand and the pull ring 309, preventing slippage during movement.

[0033] In the embodiments of this utility model, please refer to Figure 5The limiting structure 4 includes two fixed blocks 401 and two auxiliary plates 403. The two auxiliary plates 403 are fixedly connected to the fume hood body 1. The fixed blocks 401 are fixedly connected to the cabinet door 2. The inner wall of the fixed blocks 401 is provided with a slot 402. The inner wall of the auxiliary plates 403 is provided with a sliding groove 404. The inner wall of the sliding groove 404 is slidably connected to a moving block 408 and a connecting rod 405. The connecting rod 405 is fixedly connected to the moving block 408 and slidably connected to the auxiliary plates 403. The arc surface of the connecting rod 405 is fitted with a compression spring 407. The two ends of the compression spring 407 are fixedly connected to the moving block 408 and the sliding groove 404 respectively. The side of the moving block 408 away from the fume hood body 1 is fixedly connected to a connecting block 409. The lower surface of the connecting block 409 is fixedly connected to a locking block 410. When personnel need to open the cabinet door 2 to maintain the interior of the fume hood body 1, the door 2 can be limited by the locking block 410 and the locking groove 402. This prevents the door 2 from rotating due to external factors, thus improving personnel efficiency and allowing maintenance work to proceed smoothly. Two limiting rods 406 are fixedly connected to the inner wall of the slide groove 404, and these limiting rods 406 are slidably connected to the moving block 408. The limiting rods 406 limit the moving block 408, preventing it from becoming misaligned during sliding along the inner wall of the limiting groove 302.

[0034] The working principle of the easy-to-use fume hood provided by this utility model is as follows: When personnel need to fix the storage device 6 inside the fume hood body 1 for use, personnel can first move the storage device 6. The storage device 6 drives the connecting column 314 to move closer to the fixed plate 301. The connecting column 314 drives the base plate 306 to move closer to the fixed plate 301. The base plate 306 drives the connecting plate 305 to move closer to the fixed plate 301. The connecting plate 305 drives the connecting plate 303 to move closer to the fixed plate 301. The connecting plate 303 moves towards the fixed plate 301, causing the two guide blocks 304 to move closer to the fixed plate 301. The guide blocks 304 guide the connecting plate 303, facilitating its sliding into the inner wall of the limiting groove 302. This continues until the guide blocks 304 and the connecting plate 303 are fully inserted into the limiting groove 302. At this point, the base plate 306 slides on the lower surface of the fixed plate 301. During the sliding of the guide blocks 304 within the limiting groove 302, the two guide blocks 304... The inclined surface of 04 will abut against the positioning plate 308, causing the positioning plate 308 to move upward. The positioning plate 308 will then move the two pull rings 309 upward. The positioning plate 308 will also cause the spring 312 and the bellows 313 to retract. The bellows 313 can protect the spring 312 and effectively reduce the impact of environmental factors on the spring 312. Then, the pull rings 309 will also move the anti-slip sleeve 310 upward. At this time, the fixing rod 311 slides on the inner wall of the connecting groove 315 until the connecting plate 304... 5. When the positioning plate 308 abuts against the fixed plate 301, the positioning plate 308 abuts against the positioning groove 307. Then the spring 312 rebounds, causing the positioning plate 308 to move closer to the positioning groove 307 until the positioning plate 308 slides into the inner wall of the positioning groove 307. The pull ring 309 allows personnel to easily move the positioning plate 308, improving the ease of operation. The protective sleeve increases the friction between the personnel's hands and the pull ring 309, preventing slippage during the movement of the pull ring 309.

[0035] Additionally, when personnel need to maintain the interior of the fume hood body 1, they can first rotate the cabinet door 2. The cabinet door 2 will cause the fixing block 401 to rotate, moving it closer to the connecting block 409 until the fixing block 401 abuts against the inclined surface of the locking block 410. Then, the fixing block 401 will move the locking block 410 upwards, which in turn will move the connecting block 409 upwards. The connecting block 409 will then move the moving block 408 upwards, which in turn will move the connecting rod 405. As the moving block 408 moves upward, it also stretches the compression spring 407. The moving block 408 slides on the arc surface of the two limiting rods 406. The limiting rods 406 can limit the moving block 408 and prevent it from being misaligned during the sliding process on the inner wall of the limiting groove 302 until the slot 402 corresponds to the locking block 410. At this time, the compression spring 407 rebounds and drives the locking block 410 to move closer to the slot 402 until the locking block 410 slides into the inner wall of the slot 402.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
