[0002] In the laboratory, the fume hood is one of the important equipment. However, the traditional fume hood usually cannot flexibly adjust the internal space, and its internal space is usually designed to be large. When exhausting air, the negative pressure formed in the cabinet is small, and there is a risk of internal harmful gas leakage. Therefore, it is necessary to design a fume hood with adjustable side panels to solve the above defects. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and proposes to design a fume hood with adjustable side panels. The size of the internal space of the cabinet can be adjusted by adjusting the side panels. The internal space of the cabinet is reduced, so that the negative pressure in the cabinet is increased under the same exhaust volume, effectively avoiding the risk of internal harmful gas leakage.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A fume hood with adjustable side panels comprises a cabinet body, a top panel is arranged on the top of the cabinet body, a movable side panel is arranged below the top panel, the top of the movable side panel is connected to the top panel, and the bottom is connected to the inner lining panel arranged on the side of the cabinet body; the movable side panel adopts a telescopic structure; the top of the movable side panel can make a linear motion on the top panel along the length direction of the cabinet body and / or the bottom can make a linear motion on the inner lining panel in the vertical direction. The above structural arrangement can adjust the inclination angle of the movable side panel relative to the inner lining panel, thereby realizing the size adjustment of the internal space of the fume hood, making it fully utilized, and avoiding the problem of harmful gas leakage caused by too small negative pressure inside the cabinet.

[0006] Furthermore, the top plate is provided with a horizontal slide in the length direction of the cabinet, a pulley is installed on the horizontal slide, and a connecting piece is installed on the pulley; the connecting piece is hinged to the top of the movable side plate, so that the top of the movable side plate can rotate relative to the top plate, and can also move linearly along the horizontal slide through the pulley.

[0007] Furthermore, the connecting piece may be a hook, a hinge, etc.

[0008] Furthermore, the top plate is provided with two parallel horizontal slideways in the length direction of the cabinet.

[0009] Furthermore, a vertical slide is provided on the inner lining plate, bolts are installed on the vertical slide, and the bottom of the movable side plate can slide up and down along the vertical slide and be fixed by bolts.

[0010] Furthermore, the movable side panel comprises two overlapping movable panels, on which a slide groove is provided, the slide grooves on the two movable panels correspond to each other, bolts are installed in the slide grooves, the two movable panels are fixed by the bolts, and the relative positions of the two movable panels can be adjusted to realize the extension and retraction of the entire movable side panel.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is clearly and completely described below in conjunction with the accompanying drawings of the specification.

[0022] Embodiment 1:

[0023] like Figure 1-4 As shown, this embodiment relates to a fume hood with adjustable side panels, which includes a cabinet body 1, a top panel 2, a movable side panel 3 and an inner lining panel 4.

[0024] The cabinet 1 is provided with a top plate 2 on the top, and two movable side plates 3 are provided below the top plate 2, namely a left movable side plate and a right movable side plate. The bottom of the left movable side plate is mounted on the inner lining plate 4 on the left side of the cabinet 1, and the bottom of the right movable side plate is mounted on the inner lining plate 4 on the right side of the cabinet 1. The movable side plate 3 adopts a telescopic structure. Specifically, Figure 5 As shown, the movable side panel 3 includes two overlapping movable panels, and the movable panels are provided with slide grooves 9, the slide grooves 9 on the two movable panels correspond to each other, and bolts 8 are installed in the slide grooves 9, and the two movable panels are fixed by the bolts 8. The relative positions of the two movable panels can be adjusted to achieve the extension and retraction of the entire movable side panel 3. Specifically, the slide groove 9 is provided with more than one, and preferably two in this embodiment, which is convenient for production and can better ensure the overall stability of the movable side panel 3.

[0025] The top of the movable side panel 3 is connected to the top panel 2. Specifically, the top panel 2 is provided with two parallel horizontal slideways 5 in the length direction of the cabinet 1, and a pulley 6 with a hook is installed on the horizontal slideway 5, and the hook is connected to the top of the movable side panel 3, so that the top of the movable side panel 3 can rotate relative to the top panel 2, and can also make a linear motion along the horizontal slideway 5 through the pulley 6.

[0026] The bottom of the movable side panel 3 is connected to the inner lining panel 4 arranged on the side of the cabinet 1. Specifically, a vertical slide 7 is arranged on the inner lining panel 4, and a bolt 8 is installed on the vertical slide 7. The bottom of the movable side panel 3 can slide up and down along the vertical slide 7 and be fixed by the bolt 8, so that the bottom of the movable side panel 3 can make a linear motion in the vertical direction on the inner lining panel 4. Among them, as a feasible embodiment, a slider is hinged on the side of the movable side panel 3 near the bottom, and the slider is placed in the vertical slide 7. The bolt 8 is fastened under the movable side panel 3 to clamp and fix the movable side panel 3. As another feasible embodiment, a slider is hinged on the bottom of the movable side panel 3, and the slider is placed in the vertical slide 7. The bolt 8 is fastened under the slider to clamp and fix the slider.

[0027] Working principle: When the utility model is used, the operator can adjust the size of the internal space of the cabinet 1 according to the actual use situation. When adjusting the internal space, first, the pulley 6 with hook is connected to the movable side panel 3, and the pulley 6 with hook can make a linear motion in the horizontal slide 5; second, the movable side panel 3 includes two movable panels that can move relative to its slide groove 9, and they are connected and fixed by bolts 8 to realize the expansion and contraction of the movable side panel 3; third, the movable side panel 3 can also move up and down relative to the vertical slide 7 of the inner lining plate 4 of the fume hood, and is connected and fixed with bolts 8. The above three adjustment methods can be selected at the same time, or two of them can be selected arbitrarily, and the inclination angle of the movable side panel 3 relative to the inner lining plate 4 can be adjusted by manual operation to realize the size adjustment of the internal space of the fume hood. Under the same exhaust volume conditions, the smaller the internal space, the higher the negative pressure, which is more conducive to preventing the overflow of harmful gases. Under the same negative pressure conditions, the smaller the internal space, the smaller the exhaust volume, the lower the energy consumption, and the lower the noise.

[0028] The above-mentioned specific implementation methods are only specific cases of the present utility model. The patent protection scope of the present utility model includes but is not limited to the above-mentioned specific implementation methods. Any appropriate changes or modifications made to them by ordinary technicians in the relevant technical field in accordance with the claims of the present utility model shall fall within the patent protection scope of the present utility model.
